[0029] like Figures 1 to 9 As shown, the present application provides a locking device for an endless rope continuous traction vehicle, comprising a vehicle body 100 and a steel wire rope 200, and further comprising a support cylinder 300 and a locking assembly, wherein the support cylinder 300 is fixed at the bottom end of the vehicle body 100, and the steel wire rope 200 passes through the support cylinder 300, and a locking assembly is arranged between the support cylinder 300 and the vehicle body 100, and the locking assembly comprises a primary hook assembly 400 and a secondary pressing assembly 500;

[0030] The primary hook assembly 400 includes a J-shaped hook 410 movably arranged inside the support tube 300, and a hook groove 420 is arranged on the J-shaped hook 410. In the initial stage, the wire rope 200 is movably arranged in the hook groove 420 of the J-shaped hook 410. The support tube 300 is provided with a through groove 430 for the J-shaped hook 410 to pass through. A power piece 440 is fixed to the top of the J-shaped hook 410, and the power piece 440 is fixed to the bottom end of the vehicle body 100. The power piece 440 adopts an electric telescopic rod, which is fixed to the bottom end of the vehicle body 100. A connecting piece is fixed to the free end of the electric telescopic rod. The bottom end of the connecting block is fixedly connected to the J-shaped hook 410. The power piece 440 is used to drive the J-shaped hook 410 to move up and down. An arc-shaped locking piece 450 is arranged at the bottom end of the vehicle body 100 corresponding to the position of the J-shaped hook 410, and a pressure sensor 600 is arranged on the arc-shaped locking piece 450.

[0031] The secondary pressing assembly 500 includes an arc-shaped pressing member 510, on which a driving member 520 is disposed, and the driving member 520 is fixed to the bottom end of the vehicle body 100. The driving member 520 adopts an electric telescopic rod, which is fixed to the bottom end of the vehicle body 100. The free end of the electric telescopic rod is fixedly connected to the arc-shaped pressing member 510. Both sides of the top end of the support tube 300 are provided with through openings 530 that are connected to the inside of the support tube 300 and for the arc-shaped pressing member 510 to pass through. The pressure sensor 600 and the driving member 520 are electrically connected.

[0032] Further specific description: Through the design of the first-level hook assembly 400 and the second-level pressing assembly 500, the steel wire rope 200 in the support tube 300 can be locked in two stages, and the locking can be strengthened to ensure the safe use of the vehicle body 100, avoid the phenomenon of collision between the front and rear vehicles, enhance safe operation, and reduce safety accidents; the pressure sensor 600 and the driving member 520 are electrically connected, and when the pressure sensor 600 senses the set pressure value, the signal is transmitted to the driving member 520, and the driving member 520 operates.

[0033] Specifically, the arc-shaped locking member 450 and the arc-shaped pressing member 510 have the same size and are both compatible with the steel wire rope 200 .

[0034] Specifically, a plurality of insert cones 511 are fixed to the bottom end of the arc-shaped pressing member 510 .

[0035] To further explain in detail: the bottom end of the arc-shaped pressing member 510 is provided with an insert cone 511 to enhance the pressing effect.

[0036] Specifically, a U-shaped fixing frame is fixed to the bottom end of the vehicle body 100 , the bottom end of the U-shaped fixing frame is fixedly connected to the top end of the arc-shaped locking member 450 , and the pressure sensor 600 is installed on the inner wall surface of the U-shaped fixing frame.

[0037] Specifically, the J-shaped hook 410 is movably connected in the through slot 430 , and a slot 431 is formed at the top of the through slot 430 .

[0038] To be further described in detail: the J-shaped lifting hook 410 extends to the top of the support tube 300 through the through groove 430 and the slot 431 on the support tube 300, and drives the wire rope 200 in the hook groove 420 to move up to the arc-shaped locking piece 450, and the wire rope 200 is locked through the cooperation of the J-shaped lifting hook 410 and the arc-shaped locking piece 450.

[0039] Specifically, the arc-shaped locking member 450 is movably connected in the hook groove 420 of the J-shaped hook 410 .

[0040] Further specific description: Through the above structural design, it is convenient for the arc-shaped locking member 450 to enter the inner side of the J-shaped lifting hook 410 and lock and press the wire rope 200 inside the J-shaped lifting hook 410.

[0041] Specifically, connection blocks are fixed on both sides of the support tube 300 , and the top end of the connection block is fixedly connected to the bottom end of the vehicle body 100 .

[0042] When the locking device of the endless rope continuous traction vehicle of the embodiment of the present application is actually used: the power member 440 is started, the free end of the electric telescopic rod of the power member 440 contracts, driving the J-shaped hook 410 to move upward, the J-shaped hook 410 hooks and pulls the wire rope 200 upward, lifts the wire rope 200, and the wire rope 200 moves upward to contact the arc-shaped locking member 450. As the free end of the electric telescopic rod continues to contract, the arc-shaped locking member 450 locks and presses the wire rope 200 into the hook groove 420. At the same time, the arc-shaped locking member 450 is resisted by the wire rope 200. When the arc-shaped locking member 450 senses pressure and the pressure value of the pressure sensor 600 on the arc-shaped locking member 450 reaches the set value, a signal is transmitted to the electric telescopic rod of the driving member 520, and the free end of the electric telescopic rod is extended, driving the arc-shaped pressing member 510 to move downward, pressing the wire rope 200 in the support tube 300, thereby enhancing the locking effect and further preventing the wire rope 200 from slipping off between the J-shaped hook 410 and the arc-shaped locking member 450. In addition, there is a cone 511 at the bottom end of the arc-shaped pressing member 510 to enhance the pressing effect.

[0043] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
