[0018] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0019] As Figure 1-2 shown, the present invention discloses a trailer rope reel for emergency towing, including a steel wire rope 10 and a steel wire rope reel 20 installed on a vehicle frame 50. One end of the steel wire rope 10 is connected to the vehicle frame 50 and the other end is connected to a drag soft rope 30. The main body of the steel wire rope 10 is constrained within the steel wire rope reel 20. The steel wire rope reel 20 is equipped with a rope releasing device 40, and the rope releasing device 40 is connected to the drag soft rope 30. When the drag soft rope 30 is pulled, the rope releasing device 40 is opened. When the rope releasing device 40 is opened, the steel wire rope reel 20 releases the constraint on the steel wire rope 10, and the drag soft rope 30 drags the steel wire rope 10.

[0020] During use, before the equipment vehicle enters the dangerous area, one end of the drag soft rope 30 is fixed in the safe area. When the equipment vehicle enters the dangerous area, the drag soft rope 30 is released, so that the drag soft rope 30 follows the equipment vehicle into the dangerous area for operation. One end of the steel wire rope 10 is fixed on the vehicle frame 50 of the equipment vehicle, and the other end of the steel wire rope 10 is connected to the drag soft rope 30. The main body of the steel wire rope 10 is constrained by the steel wire rope reel 20 and will not scatter. When the equipment vehicle breaks down and needs to be towed, the operator in the safe area pulls the drag soft rope 30. After the drag soft rope 30 is pulled, the rope releasing device 40 is opened. After the rope releasing device 40 is opened, the main body of the steel wire rope 10 is no longer constrained by the steel wire rope reel 20, and the steel wire rope 10 is in a loose state. At this time, when the drag soft rope 30 is pulled, the drag soft rope 30 will drag the steel wire rope 10, drag the steel wire rope 10 to the safe area, and then the equipment vehicle can be towed to the safe area through personnel and equipment.

[0021] It should be noted that for the above solution, the force required to activate the rope releasing device 40 needs to be reasonably set so that when the equipment vehicle is operating normally, the movement of the equipment vehicle during operation will not affect the dragging soft rope 30, causing the rope releasing device 40 to be accidentally activated.

[0022] Furthermore, the wire rope reel 20 includes a reel shaft 21 connected to the vehicle frame 50. A reel wall 22 is installed on one side of the reel shaft 21 close to the vehicle frame 50, and a rope releasing device 40 is installed on the other side of the reel shaft 21. The main body of the wire rope 10 is located between the reel wall 22 and the rope releasing device 40 and is wound around the reel shaft 21.

[0023] In the solution, the axis of the reel shaft 21 can be parallel to the working surface of the equipment vehicle or intersect downward with the working surface. The direction of the reel shaft 21 should be conducive to the release of the wire rope 10 when it is dragged. Winding the wire rope 10 around the reel shaft 21 can keep the wire rope 10 restricted by the wire rope reel 20 when it is not released, preventing the wire rope 10 from spreading.

[0024] Furthermore, when the rope releasing device 40 is activated, it is used to release the restraint on the wire rope 10, and there are various ways to achieve this. One of them can be to open a positioning groove 211 at the place where the rope releasing device 40 is installed on the reel shaft 21. The rope releasing device 40 includes a clamp 41 and symmetrically structured clamping plate one 42 and clamping plate two 43; Clamping plate one 42 is provided with a reel shaft clamping interface one (not shown in the figure) and a wire rope clamping interface one 422. Clamping plate one 42 is connected to a sleeve one 423. Clamping plate two 43 is provided with a reel shaft clamping interface two 431 and a wire rope clamping interface two (not shown in the figure). Clamping plate two 43 is connected to a sleeve two 433; When clamping plate one 42 and clamping plate two 43 are used in combination, the reel shaft clamping interface one and the reel shaft clamping interface two 431 are combined and clamped in the positioning groove 211. The wire rope clamping interface one 422 and the wire rope clamping interface two are combined and the wire rope 10 is clamped in the middle. The sleeve one 423 and the sleeve two 433 are combined and the clamp 41 locks the sleeve one 423 and the sleeve two 433; The clamp 41 is connected to the dragging soft rope 30, and when the dragging soft rope 30 pulls the clamp 41, the clamp 41 is opened.

[0025] In the above solution, the structures of clamping plate one 42 and clamping plate two 43 are symmetric. The clamp 41 keeps clamping plate one 42 and clamping plate two 43 combined by locking sleeve one 423 and sleeve two 433. When clamping plate one 42 and clamping plate two 43 are combined, the wire rope 10 is restricted by the wire rope clamping interface one 422 and the wire rope clamping interface two and will not disperse. The reel shaft clamping interface one and the reel shaft clamping interface two 431 are combined and clamped in the positioning groove 211 to keep the relative position of clamping plate one 42 and clamping plate two 43 fixed relative to the reel shaft 21 and not slide. At the same time, anti-rotation and positioning devices corresponding to the reel shaft clamping interface one and the reel shaft clamping interface two 431 can also be set in the positioning groove 211 to keep the positions of clamping plate one 42 and clamping plate two 43 fixed and not rotate.

[0026] Preferably, the rope releasing device 40 can also adopt a plug-in structure. The whole rope releasing device 40 is plugged into the top of the reel shaft 21, and the rope releasing device 40 is separated from the reel shaft 21 when being pulled by the drag soft rope 30.

[0027] Furthermore, the clamp 41 includes a first hoop body 411, a second hoop body 412, a buckle 413 and an elastic hook piece 414. One end of the first hoop body 411 is connected to the buckle 413, and the other end is rotatably connected to the second hoop body 412. One end of the second hoop body 412 is connected to the elastic hook piece 414. The buckle 413 is connected to the drag soft rope 30, and the buckle 413 is provided with a latch block (not shown in the figure). When the clamp 41 is used to lock the first sleeve 423 and the second sleeve 433, the hook piece 414 hooks and presses the latch block. When the drag soft rope 30 pulls the buckle 413, the latch block disengages from the hooking pressure of the hook piece 414.

[0028] In the solution, the hook piece 414 has elasticity, and the magnitude of its elasticity can be set as required. The contact surface of the latch block pressed by the hook piece 414 should have a smooth surface, so that when the buckle 413 is pulled by the drag soft rope 30, the latch block can be driven to squeeze the hook piece 414, so that the latch block gets rid of the hooking pressure of the hook piece 414. After the latch block is separated from the hook piece 414, the first hoop body 411 and the second hoop body 412 rotate and open, releasing the locking of the first sleeve 423 and the second sleeve 433. At this time, the first sleeve 423 and the second sleeve 433 are not fixed and fall under the drive of the steel wire rope 10, thereby releasing the restraint on the steel wire rope 10.

[0029] Furthermore, the clamp 41 is connected to the first clamping plate 42 and the second clamping plate 43 through a tether 80. The first clamping plate 42 and the second clamping plate 43 can be dragged to a safe area by the drag soft rope 30 along with the clamp 41 for recycling.

[0030] Furthermore, the tether 80 can be connected to the first clamping plate 42 and the second clamping plate 43 by connecting the first clamping plate 42 to a first supporting plate 424. The first supporting plate 424 is provided with a first through hole 4241, and the tether 80 passes through the first through hole 4241 and is fixed by a knot between the tether 80 and the first through hole 4241. The second clamping plate 43 is connected to a second supporting plate, and the second supporting plate is provided with a second through hole. The tether 80 passes through the second through hole and is fixed by a knot between the tether 80 and the second through hole.

[0031] The first supporting plate 424 can simultaneously provide support for the first sleeve 423, and the second supporting plate can simultaneously provide support for the second sleeve 433, facilitating the fitting of the first sleeve 423 and the second sleeve 433.

[0032] Furthermore, when the drag soft rope 30 is stored, it is placed in a soft rope drum 60, and the soft rope drum 60 is movably connected to the vehicle frame 50.

[0033] When working in a non - hazardous area, the flexible rope drum 60 is placed on the equipment vehicle, and the towing flexible rope 30 is placed inside the flexible rope drum 60. The equipment vehicle can be equipped with a box for storing the flexible rope drum 60. When the equipment vehicle enters the hazardous area for work, the flexible rope drum 60 is taken out from the equipment vehicle and placed in a safe area. After the work is completed, the flexible rope drum 60 can use the rope - winding device to wind up the towing flexible rope 30.

[0034] Furthermore, the vehicle frame 50 is equipped with a trailer hitch 70, and one end of the steel wire rope 10 is connected to the trailer hitch 70. By setting a fixed trailer hitch 70 on the vehicle frame 50 of the equipment vehicle, one end of the steel wire rope 10 can be firmly fixed, and the trailer hitch 70 is set at the stress point of the equipment vehicle suitable for being towed.

[0035] Principle of the present invention: The present invention discloses an emergency towing rope reel for use in rescue when an unmanned equipment vehicle breaks down in a hazardous area during mine tunnel operations. The present invention connects a towing flexible rope 30 to the steel wire rope 10 and installs a rope - releasing device 40 on the wire rope reel 20. When an unmanned equipment vehicle is trapped in a hazardous area due to a fault, an operator in a safe area can activate the rope - releasing device 40 through the pre - reserved towing flexible rope 30, then drag one end of the steel wire rope 10 to the safe area, and then implement the rescue through personnel and equipment.
