[0002] In mining operations, a cage is a common conveying device for transporting personnel and ore materials. The cage door curtain on the cage is a protective curtain used to protect the safety of materials or personnel during the lifting process of the hoisting equipment in the coal mine shaft.

[0003] Existing protective door curtains are usually provided with rings at both ends of the railing and are placed on a vertically arranged slide bar and opened by manual lifting (such as Figure 5 As shown), during the use of this type of door curtain, when the mine car enters the cage, the cage door curtain is not raised and collides with the railing. After the collision, the railing of the cage door curtain will be deformed, making it difficult to lift. At the same time, due to the working environment, the cage door curtain will rust, resulting in greater friction, which makes it very difficult to lift. It is very easy to cause safety accidents, resulting in immeasurable consequences for people or objects, and some unnecessary economic expenses. In addition, it is very cumbersome to replace the railing, and the labor intensity of the operator will be increased. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0021] like Figure 1As shown, a cage door curtain for mines comprises a cage body 1 and an entrance and exit on one side thereof, L-shaped slideways 3 are respectively arranged on both sides of the entrance and exit of the cage body 1, a lubrication assembly is arranged on the outer side of the corresponding L-shaped slideway 3, a plurality of pulleys 4 are slidably connected in the corresponding L-shaped slideway 3, a cage door curtain is supported between two corresponding pulleys 4, the cage door curtain is composed of a plurality of adjustable railings 2, and a traction assembly for raising and lowering the cage door curtain is connected and fixed to the cage door curtain.

[0022] like Figure 1 , 2 As shown in Figure 3, the railing 2 includes a connecting rod 5 connected and fixed to the corresponding pulley 4, and a pre-change rod 6 is slidably supported between the connecting rods 5. The connection between the connecting rod 5 and the pre-change rod 6 is arranged on a boss and a groove that match each other. A countersunk hole 19 is arranged on the contact surface of the boss and the groove and a tension spring 17 is arranged inside. Arc-shaped spring pieces 18 for clamping the boss are connected and fixed on both sides of the inner wall of the groove.

[0023] like Figure 4 As shown, the lubrication assembly includes an oil storage tank 11 fixed at the lower part of the corresponding L-shaped slide 3, a filter plate 12 that can be pulled out and replaced is arranged on the upper part of the oil storage tank 11, an oil delivery pipe 13 is connected to the bottom of the oil storage tank 11, the oil delivery pipe 13 extends upward to communicate with the oil filling box 15, the oil filling box 15 is connected and fixed to the L-shaped slide 3 and a plurality of oil filling holes 16 are opened on the L-shaped slide 3.

[0024] like Figure 1 As shown, the traction assembly includes a plurality of fixed pulleys 9 fixed on both sides of the cage body 1, a traction rope 8 is wound around the fixed pulley 9, one end of the traction rope 8 is fixed to the railing 2 at the lower end of the cage door curtain, and the other end is connected and fixed to a counterweight block 10.

[0025] like Figure 1 , 3 As shown, the corresponding groove opening faces the outside of the cage body 1.

[0026] like Figure 1 As shown, adjacent railings 2 are hinged and fixed via support rods.

[0027] like Figure 1 , 4 As shown, an oil injection pump 14 is installed on the oil delivery pipe 13.

[0028] A pluggable pin shaft 7 is provided at the lower portion of the corresponding L-shaped slideway 3 .

[0029] The implementation principle of a cage door curtain for a mine in the embodiment of the present application is:

[0030] When the cage body is being transported, the railing 2 is pulled down to pull the cage door curtain, and the counterweight 10 will generate downward gravity. When the cage door curtain is pulled, the oil filling pump 14 is started, and the oil filling pump 14 will input the lubricating oil in the oil storage tank 11 into the oil filling box 15 along the oil delivery pipe 13. After being input into the oil filling box 15, the lubricating oil will slowly flow from the oil outlet 16 to the side wall in the L-shaped slideway. When the cage door curtain moves, the pulleys 4 on both sides will reduce the friction with the L-shaped slideway 3, so that the movement is smoother. When the cage door curtain is pulled to the corresponding position, the pin shaft 7 is inserted to prevent the cage door curtain from being pulled up again by the counterweight 10;

[0031] When transporting a mine car, if the mine car collides with the railing, the pre-change rod 6 will slide and produce a corresponding gap with the connecting rod 5, and the tension spring 17 will be stretched to produce a rebound force. When the mine car is unloaded, the pre-change rod 6 will be pulled back under the action of the rebound force of the spring and fit into the groove of the connecting rod again, thereby preventing the railing from being deformed by the mine car, better ensuring the integrity of the cage door curtain, and preventing a series of problems caused by the deformation of the cage door curtain, and reducing the labor intensity of the operator;

[0032] If the cage door curtain is to be opened, the pin shaft 7 is pulled out, and after being pulled out, the cage door curtain will be pulled up while the counterweight block falls, thereby opening the cage door curtain. The whole process saves time and effort, better completes the opening and closing work of the cage door curtain, and better ensures the safe production of the enterprise.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
