Design and manufacture of screen locking device for rapid replacement of rotary vibrating screen

In the current rotary vibrating screen, the connection of each layer of the screen grid is fastened by a ring and a bolt. The main method is to weld a bolt nose and a bolt buckle to the two ends of the opening of the beam ring. The bolt nose and the bolt buckle are equipped with screws. And its nuts. This structure requires a wrench when connecting or disassembling each layer of screen grids. If it is a larger type of rotary vibrating screen, two people are required to complete it, and the loading and unloading is very laborious and time-consuming. The purpose of the utility model is to design a fast locking device of the rotary vibrating screen beam ring which is fast in loading and unloading and labor-saving. 

The technical solution of the utility model is completed in the following way. It includes a tie ring, a screw rod and a nut. It is characterized in that an elastic bolt holder with the end prying outward is fixed on the outside of both ends of the tie ring opening. The frame is fixed on the side of the beam ring with a clamp with a lower port pressed against the outer surface of the beam ring. One of the bolt frames is pivotally connected to an automatic wrench, and the inner side of the shaft end of the automatic wrench is provided with a rotating shaft to connect a movable chuck. 

The middle slot of the shaft end of the automatic wrench is equipped with a spring piece that is fixed at one end to the movable chuck and can lock or loosen the automatic wrench by the cooperation of the step and the elbow with the groove. The other end of the movable chuck can be locked with the screw. Tighten or loosen the opening groove of the screw head, and a fork shaft on the screw shaft is connected to the bolt frame at the other end of the beam ring opening. The fork shaft on the screw can be arranged on an extension wire sleeve integrated with the nut, and the length of the screw can be effectively adjusted by rotating the nut. Using this device without any tools, one person can complete the assembly and disassembly of the rotary vibrating screen grid, and greatly shorten the assembly and disassembly time. Fig. 1 is a schematic diagram of the structure of the utility model; Fig. 2 is a 4-way view of the automatic wrench and self-locking spring sheet in Fig. 1; Fig. 3 is an 8-way view of the bezel and the locking clip in Fig. 1. In the figure, 1. lashing ring, 2. automatic wrench, 3. self-locking spring plate, 4. rotating shaft of automatic wrench and movable clamp, 5. movable chuck, 6. screw, 7. fork shaft, 8. adjusting nut , 9. Elastic bolt frame, 10. Clamping. 

The utility model is an improvement on the existing beam ring of a rotary vibrating screen. The main purpose of the utility model is to fix an elastic bolt frame 9 on the outside of both ends of the opening of the beam ring 1. The clamp 10 is fixed on the side with a lower port pressed on the outer surface of the beam ring. One of the bolt holders is axially connected with an automatic wrench 2. The inner side of the shaft end of the automatic wrench is provided with a rotating shaft to rotate and connect a movable chuck 5. The middle slot of the wrench shaft end is equipped with a self-locking spring plate 3 that is fixed at one end to the movable chuck and can lock or loosen the automatic wrench with the step and elbow. The other end of the movable chuck has a screw 6 In conjunction with the opening groove that can clamp or loosen the screw head, a fork shaft 7 on the screw is axially connected to the bolt frame at the other end of the beam ring opening. The fork shaft on the above-mentioned screw is arranged on an extension wire sleeve integrated with the nut, and the length of the screw can be effectively adjusted by rotating the nut. 

Design and manufacture of screen locking device for rapid replacement of rotary vibrating screen

The fork shaft on the above-mentioned screw is arranged on an extension wire sleeve integrated with the nut, and the length of the screw can be effectively adjusted by rotating the nut. The operation steps of using this device are as follows. When installing, first adjust the adjusting nut by hand to make the lock distance on the screw match the opening distance of the tie ring, and then press down the automatic wrench by hand. The self-locking spring is from the shaft end of the automatic wrench. Pass through the groove, press the wrench by the step and the elbow, the opening at the end of the movable chuck clamps the screw head to lock the two ring openings, and the screen grid is fixed. When disassembling, press down the self-locking spring sheet by hand and pull the automatic wrench upwards. The movable chuck is opened and automatically falls and separates from the screw head to complete the disassembly work. 1. Rotary vibrating screen beam ring quick locking device, which includes a beam ring, a screw rod, and a nut. It is characterized in that an elastic bolt frame with ends being picked up is fixed on the outside of both ends of the beam ring opening. 

On the side of the beam ring is fixed a clamp with a lower port pressed against the outer surface of the beam ring. One of the bolt holders is connected to an automatic wrench. The inner side of the shaft of the automatic wrench is provided with a rotating shaft to connect a movable chuck and automatic wrench shaft. The middle slot at the end is equipped with a spring piece that is fixed at one end to the movable chuck and one end is matched with the step and elbow to lock or loosen the automatic wrench. The other end of the movable chuck can be locked or loosened with the screw. The open slot of the screw head is opened, and a fork shaft on the screw is axially connected to the bolt frame at the other end of the beam ring opening. 2. The quick-locking device for the ring of a rotary vibrating screen according to claim 1, wherein the fork shaft on the screw can be set on an extension wire sleeve integrated with the nut. 

The fast locking device for the beam ring of the rotary vibrating screen, which includes a beam ring, a screw rod and a nut, is characterized in that an elastic bolt frame whose ends are pried outward are respectively fixed on the outer sides of the two ends of the beam ring opening, and the bolt frame rests on the beam The ring side is fixed with a clamp with a lower port pressed against the outer surface of the beam ring. One of the bolt holders is connected to an automatic wrench. The inner side of the shaft end of the automatic wrench is provided with a rotating shaft to connect a movable chuck. 

The middle of the shaft end of the automatic wrench The slotted hole is equipped with a spring leaf that is fixed at one end to the movable chuck and one end is matched with the step and elbow to lock or loosen the automatic wrench. The other end of the movable chuck is matched with the screw to lock or loosen the screw. The opening groove of the head, the screw rod is provided with a fork shaft which is connected to the bolt frame at the other end of the beam ring opening. Using this device without any tools, one person can complete the assembly and disassembly of the rotary vibrating screen grid, and can greatly shorten the time for assembly and disassembly of the rotary vibrating screen.
