When the wire rope breaks, the pressure sensor detects that the tension on the wire rope has changed greatly, and it will send a signal to the control at the first time. device, and then through the control device to control the second telescopic device to work, the second telescopic device can drive the limit locking block to clamp the lifting slide rail body in time under the cooperation of the limit support plate and the support prism, and fix the limit on it. Avoid the phenomenon of the frame body falling.

During the lowering process of the frame body, it is necessary to control the first telescopic device to drive the limit rod to move with the cooperation of the moving support plate, and push the support bearing plate out of the second groove through the limit rod, and then the electric hoist drives one end of the wire rope to descend. , after descending to the specified position, the first telescopic device drives the limit pull bar away from the support bearing plate under the cooperation of the moving support plate. With the cooperation of the plug-in rod, push the support bearing plate into the second groove, and then cooperate with the electric hoist and the wire rope to continue to drive the frame body down slightly until the circular limit protrusion is inserted into the circular limit groove. After connecting and matching, the supporting load plate can support and lift the limit support block. Similarly, during the lowering process of the frame body, the steel wire rope will bear the tension through the wire rope connecting ring, connecting rod, sliding limit plate and The U-shaped fixed connection seat cooperates and transmits to the pressure sensor for real-time monitoring. When the wire rope breaks, the pressure sensor detects a large change in the tension on the wire rope and will send a signal to the control device immediately. The difference in the rising process is that the control device will control the first telescopic device and the second telescopic device to work at the same time, and the first telescopic device will drive the limit pull bar away from the supporting plate with the cooperation of the moving support plate, so that the spring will Under the cooperation of an arc-shaped guide plug-in rod and a second arc-shaped guide plug-in rod, the support bearing plate is pushed into the second groove, and the second telescopic device is driven by the cooperation of the limit support plate and the support prism The limit locking block clamps the body of the lifting slide rail and fixes the limit to prevent the frame body from falling.
