[0033] An anti-rope-off blocking rod 64 is detachably installed between two adjacent brackets 52. By setting the anti-rope-off blocking rod 64, the anti-rope-off blocking rod 64 can effectively prevent the first main steel wire rope 53 and the second main steel wire rope 54 from being loosened and thus coming off the steel wire rope drum 51.

The anti-rope-off stopper rod 64 is fixed between two adjacent brackets 52 by the mounting bolt 642 and the mounting nut 643. By setting the mounting bolt 642, the waist groove 641 and the mounting nut 643, the anti-rope-off stopper rod 64 can be conveniently fixed between the two brackets 52. At the same time, the setting of the waist groove 641 makes it easy to adjust the installation height of the anti-rope-off stopper rod 64.

[0035] The tensioning assembly 7 includes a plurality of steel wire rope screws 71, one end of which penetrates the vehicle loading plate 3, and one end of the first auxiliary steel wire rope 41 and the second auxiliary steel wire rope 42 are respectively fixedly mounted on the other end of the corresponding steel wire rope screw 71. By setting the steel wire rope screw 71, when the steel wire rope screw 71 descends on the vehicle loading plate 3, the first auxiliary steel wire rope 41 and the second auxiliary steel wire rope 42 can be pulled, so that the tension of the first auxiliary steel wire rope 41 and the second auxiliary steel wire rope 42 can be adjusted; Two first nuts 72 are installed on the middle thread of the wire rope screw 71, and a cushion block 76 is fixedly installed on the lower surface of the vehicle loading plate 3. The upper surface of the first nut 72 is in active contact with the lower surface of the cushion block 76. By setting the first nut 72, when the first nut 72 is threadedly rotated and raised on the wire rope screw 71, it is pressed against the lower surface of the cushion block 76, thereby fixing the wire rope screw 71, and further limiting the tension of the adjusted No. 1 auxiliary wire rope 41 and No. 2 auxiliary wire rope 42; One end of the wire rope screw 71 is threadedly rotatably installed with two second nuts 73, one end of the wire rope screw 71 is sleeved with a tension spring 74, one end of the tension spring 74 is fixedly connected to the lower surface of the cushion block 76, and the other end of the tension spring 74 is fixedly connected to a fixing seat 75, the wire rope screw 71 passes through the fixing seat 75, and the fixing seat 75 is located between the second nut 73 and the first nut 72. By arranging the first nut 72, the second nut 73, the tension spring 74 and the fixing seat 75, when the second nut 73 is threadedly rotated on the wire rope screw 71 During lifting, the degree of contraction or extension of the tension spring 74 can be adjusted through the fixed seat 75. When the No. 1 auxiliary steel wire rope 41 and the No. 2 auxiliary steel wire rope 42 are in the winding operation, the No. 1 auxiliary steel wire rope 41 and the No. 2 auxiliary steel wire rope 42 pull the vehicle loading plate 3 up through the wire rope screw 71, and the wire rope screw 71 contracts the tension spring 74 through the first nut 72, the second nut 73 and the fixed seat 75. When the tension spring 74 contracts to the maximum value, the vehicle loading plate 3 rises again, so that the vehicle loading plate 3 has a certain buffer space when it starts to rise.

[0036] The alarm assembly 8 includes a plurality of U-shaped frames 81, a plurality of spring detection switches 82 and a plurality of pulleys 83. One end of the U-shaped frame 81 can be detachably mounted on the longitudinal beam 2, the spring detection switch 82 is fixedly mounted on one end of the inner wall of the U-shaped frame 81, and the pulley 83 is rotatably mounted on one end of the spring detection switch 82. The No. 1 auxiliary steel wire rope 41 and the outer wall of the pulley 83 are in active contact. By setting the spring detection switch 82 and the pulley 83, the spring detection switch 82 is an integrated device. When the No. 1 auxiliary steel wire rope 41 is tensioned, the tensioning force of the No. 1 auxiliary steel wire rope 41 itself compresses the spring of the spring detection switch 82, so that the switch of the spring detection switch 82 is closed, and the vehicle can operate normally at this time. When the No. 1 auxiliary steel wire rope 41 is loose, under the action of the spring of the spring detection switch 82 itself, the switch of the spring detection switch 82 is disconnected, an alarm is realized, and the operation is stopped to prevent the vehicle loading plate 3 from tilting.

[0037] Working principle: when the vehicle loading plate 3 needs to be lifted or lowered, the driving motor 6 is first started, and the driving shaft of the driving motor 6 rotates the driving sprocket 61, and cooperates with the action of the chain 63 to rotate the driven sprocket 62, and the driven sprocket 62 rotates the wire rope drum 51, and the wire rope drum 51 reels and unwinds the No. 1 main wire rope 53 and the No. 2 main wire rope 54, and the No. 1 main wire rope 53 and the No. 2 main wire rope 54 synchronously rewind and unwind the No. 1 auxiliary wire rope 41 and the No. 2 auxiliary wire rope 42 through the No. 2 wire rope clamp group 55, the wire rope connecting seat 48 and the No. 1 wire rope clamp group 49, and the No. 1 auxiliary wire rope 41 and the No. 2 auxiliary wire rope 42 control the vertical lifting of the vehicle loading plate 3 through the wire rope screw 71 during the rewinding and unwinding process; During the lifting process of the vehicle loading plate 3, when the No. 1 auxiliary steel wire rope 41 and the No. 2 auxiliary steel wire rope 42 pull the vehicle loading plate 3 up or down through the steel wire rope screw 71, the steel wire rope screw 71 contracts or stretches the tension spring 74 through the first nut 72, the second nut 73 and the fixing seat 75. When the tension spring 74 contracts or stretches to the maximum value, the vehicle loading plate 3 is lifted and lowered again, so that the vehicle loading plate 3 has a certain buffer space when it starts to lift and lower. At the same time, during the lifting and lowering process of the vehicle loading plate 3, when the No. 1 auxiliary steel wire rope 41 is tensioned, the tensioning force of the No. 1 auxiliary steel wire rope 41 itself compresses the spring of the spring detection switch 82, so that the switch of the spring detection switch 82 is closed, and it can operate normally at this time. If the No. 1 auxiliary steel wire rope 41 becomes loose, under the action of the spring of the spring detection switch 82 itself, the switch of the spring detection switch 82 is disconnected, an alarm is triggered, and operation is stopped to prevent the vehicle loading plate 3 from tilting.
