Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine equipment, and in particular relates to an auxiliary wire rope coiling device for a mine winch. Background Art

[0002] In the process of underground production and transportation in coal mines, mining winches are an indispensable auxiliary transportation equipment. Their working principle is as follows: the motor drives the winch drum to rotate through the reducer (or directly), one end of the wire rope is fixed on the drum, and the other end is wound around the drum, and then the container is suspended and lifted by the derrick sheave. As the drum rotates, the container is raised and lowered. In the actual underground coal mine environment, the wire rope of the mining winch is relatively humid, with heavy coal dust and variable loads. When lifting or lowering materials, the wire rope can normally rotate and wind with the drum under the force of the load. However, when the material is lifted or lowered, the wire rope has no external force. During the recovery and winding process, there are often situations such as messy winding, squeezing of the lower and upper layers, winding on one side of the drum, and large swing of the wire rope. On the one hand, it will affect the service life of the wire rope and increase costs, and it may also cause production safety accidents.

[0003] Currently known wire rope winding devices are all utility model designs for specific workplaces for collecting and recycling wire ropes, such as the "Automatic Wire Rope Winding Device" applied for and published by Chen Shuai, Chen Yuefei, and Lu Jiahao in 2022, with publication number CN217626829U, which is used to solve the technical problems of convenient disassembly and assembly of wire rope winding drums, neat winding, and prevention of wire rope swing. Zhang Shaofei applied for and published "A Mining Wire Rope Winding Device" in 2021, with publication number CN215666327U, which is used to solve the problem that the existing winding devices use manual recycling, the workload is large, and the wire rope is prone to slippage during the recycling process, which affects the recycling work.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 As shown, the utility model is a wire rope auxiliary winding device for a mining winch, comprising a fixed bracket 101, a fixed front leg 102 installed below the fixed bracket 101, a rotatable support plate 104 at the bottom of the fixed front leg 102, a rotatable rotating rear leg 103 connected to the fixed bracket 101 and the fixed front leg 102, a gear 105 installed between the fixed front leg 102 and the rotating rear leg 103, a bayonet 106 installed on the rotating rear leg 103, and a clamp 107 installed at the bottom of the rotating rear leg 103. During operation, the fixed front leg 102 is fixed in front of the mining winch, and the support plate 104 at the bottom thereof is rotatable, so the fixed front leg 102 can be applied to a relatively inclined ground, and the working stability is increased. In addition, by adjusting the number of teeth of the gear 105 using the bayonet 106, the rotation angle of the rotating rear leg 103 can be adjusted, so that the angle between the fixed front leg 102 and the rotating rear leg 103 changes, thereby adjusting the height of the bracket to adapt to winches of different heights.

[0026] The driving device installed on the side of the bracket includes a driving motor 108, a motor gear 109 is installed on the top of the driving motor 108, a screw gear 112 is connected by a chain 110, the screw gear 112 is connected to a coupling 111, and the rear end of the coupling 111 is connected to a screw 114, and the screw 114 is installed in the cross bar above the fixed bracket 101, and the two ends of the screw 114 pass through a screw bearing 115 for fixing the screw and rotating continuously. The above-mentioned driving motor 108, motor gear 109, chain 110, coupling 111 and screw gear 112 are all installed inside the explosion-proof housing 113. When working, the electric control system 112 controls the driving motor 108 to rotate, driving the motor gear 109 to rotate, and the chain 110 connecting the two sets of gears starts to move, driving the screw gear 112 to rotate, the coupling rotates accordingly, and the screw 114 rotates accordingly, thereby driving the screw base 123 on the screw to move left and right.

[0027] The screw 114 is installed inside the crossbar of the fixed bracket 101. The two ends of the screw pass through a bearing 105. The bearing is fixed in position. The screw rotates inside it. The screw converts the rotational motion into linear motion through the ball and the screw base, so the screw base 123 can move back and forth. The screw has high motion accuracy. Therefore, after being converted into linear motion, it drives the screw base 123 to move with precise distance and extremely small positioning error.

[0028] like Figure 3 As shown, first pass the bearing fixing rod 203 through the bearing transverse screw 202, then install a traveling bearing 201, then pass through another bearing fixing rod in turn, then install the second bearing, and finally pass through the third bearing fixing rod, thus forming a group of traveling wheels that can roll horizontally on the fixed bracket. According to this principle, the vertical rolling traveling wheel group is installed. The horizontal and vertical traveling wheel groups are installed around the inner position of the traveling box 122, the cross bar above the fixed bracket is closely surrounded by the traveling wheel group inside the traveling box 122, and driven by the screw base 123, the traveling wheel group moves back and forth along the cross bar.

[0029] The travel sensors 119 installed on both sides of the fixed bracket 101 are used to monitor the real-time position of the traveling box 122, so as to adjust the direction of movement of the traveling box according to the position of the wire rope during the rotation of the winch drum and the direction of winding the next circle of wire rope. The wire rope passes through the rope drum 116 and rotates under the support of the drum base 117, thereby assisting the rope winding.

[0030] The camera 118 installed on the side of the traveling box 122 is used to monitor the rotation state of the winch drum and the working process of the wire rope winding on the drum in real time. In addition, an intelligent camera can be installed to automatically identify the rotation direction and rotation speed of the winch drum, and feed the identification information back to the electronic control system. After computer calculation processing, the drive motor 108 is controlled, thereby controlling the running direction and travel speed of the traveling box 122 to achieve automatic auxiliary rope winding.
