A through hole (not shown) for the upper part of the button to pass through is provided on the upper plate, and the diameter of the through hole is smaller than the diameter of the middle part.

[0044] The rope hanging assembly includes a rope hanging plate 31, a sleeve 32 is provided at the center of the rope hanging plate, the rope hanging plate can rotate around the sleeve, a first torsion spring 33 is sleeved on the sleeve (under the action of the first torsion spring 33, the rope hanging plate will press the wire rope when in use), and a torsion spring groove 34 is provided on the rope hanging plate for placing one end of the first torsion spring; a hanging hole 35 is provided at the bottom end of the rope hanging plate for placing an external hanger; a rotating shaft 36 is provided on the bottom plate to match the sleeve, and the rope hanging plate is sleeved on the rotating shaft through the sleeve. A groove 37 is provided on the top of the rope hanging plate, and several reinforcing ribs 38 are provided in the groove (by providing the reinforcing ribs, the force between the rope and the rope during use is increased). After the rope grabbing assembly is connected to the wire rope, the rope grabbing assembly can slide along the wire rope without hindrance under its own weight. When a person falls accidentally, the bottom of the rope hanging plate presses the wire rope under force adjustment, thereby achieving locking to ensure that the person does not fall.

[0045] The L-shaped mounting seat is arranged on the bottom plate, one end of the L-shaped mounting seat is provided with the adjusting shaft 41, the adjusting shaft is provided with a second torsion spring 42, and the L-shaped mounting seat is also provided with a column 43 matched with the second torsion spring, and the two ends of the second torsion spring are located on the column and the side wall of the L-shaped mounting seat. A positioning block 44 is provided on the L-shaped mounting seat, and one end of the first torsion spring is located between the positioning block and the side wall of the L-shaped mounting seat.

[0046] The anti-inversion assembly includes a button slot 51 arranged on the L-shaped mounting seat for placing the button, a column slot 52 connected to the button slot and located below the button slot, and an anti-inversion column 53 arranged in the column slot; a locking slot 54 matched with the anti-inversion column is formed between the bottom and the middle. The bottom of the button is installed in the button slot through a spring 55.

[0047] It also includes a matching wire rope support, which includes an L-shaped mounting column 61 and a wire rope loop 62 arranged on the L-shaped mounting column. The bottom of the L-shaped mounting column is vertical, and the bottom of the L-shaped mounting column is provided with a mounting hole 64. The vertical part of the L-shaped mounting column is installed with the wire rope loop, and the wire rope loop is vertically arranged. The wire rope loop is parallel to the bottom of the L-shaped mounting column, and the side wall of the wire rope loop is provided with a threaded groove 64 for the wire rope to be inserted.

[0048] The specific use steps of the utility model are as follows: Figure 1 and Figure 2 As shown, in actual use, the device is placed in the correct position [vertically placed in the accurate position, with the pulley at the top], and the button is pressed at this time to release the restriction on the locking plate 21. At this time, the end of the locking plate with the pulley is pressed down, and the upper edge of the locking plate is away from the rope groove 14. At this time, the rope groove 14 is facing the wire rope, and the wire rope is located in the groove of the pulley. The force on the end of the locking plate is released, and the locking plate returns to the initial position under the action of the second torsion spring. The locking plate blocks the rope groove to prevent the wire rope from running out during use, thereby ensuring safety in use.

[0049] When in use, the external hook is hung on the hanging hole 35. During use, the top of the hanging rope plate is close to the steel wire rope and squeezed under the action of its own gravity. Due to the presence of the reinforcing ribs 38, the effect of the hanging rope plate and the steel wire rope is increased, further improving the safety performance during use.

[0050] At the same time, if Figure 3 , Figure 4 As shown, in actual use, due to the accurate position, the anti-inverted hanging column 53 is at the bottom of the column groove 52 under the action of its own gravity, that is, away from the button, and the button can be pressed normally.

[0051] When the device is taken, the position is reversed. Figure 5 At this time, the anti-inverted hanging column 53 moves into the locking groove 54 of the button under the action of its own gravity. At this time, the button cannot be pressed, which prevents the device from being installed with the wire rope, thereby avoiding inverted installation and further improving the safety of the device.

[0052] At the same time, since the steel wire rope may shake during actual use, in order to solve the above problem, the device is equipped with a steel wire rope support. The L-shaped mounting column 61 is fixed to an external fixture through the mounting hole 63, and then the rope is wrapped around the threaded notch 64 and inserted into the steel wire rope sleeve 62, thereby ensuring the stability of the steel wire rope. Figure 6 .

[0053] Through the above method, the utility model provides a rope grabbing device, which forms a placement groove for the rope to pass through by bending one side of the bottom plate into a semi-cylindrical shape, and cooperates with one side of the upper plate, and uses a rope locking assembly composed of a locking plate, a pulley and a button to lock the placement groove to prevent the rope from running out, thereby achieving the purpose of rapid installation of the rope grabbing device and quality of use of the rope grabbing device.

[0054] The above is only a preferred embodiment of the rope grabbing device disclosed in the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all belong to the protection scope of the utility model.
