DETAILED DESCRIPTION

[0020] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0022] In order to prevent adjacent carriages from detaching from each other, a connecting device needs to be set between the carriages to ensure normal power transmission. The connecting device includes at least two parts, which are locked and limited by a positioning pin.

[0023] The locating pin is inserted between the two connecting parts under the action of gravity. During the operation of the mine car, the locating pin may be detached due to unreasonable fastening methods, improper installation and maintenance, and material fatigue. Or the mine car may collide or hit during use, which may also cause the locating pin to be damaged and fall off, causing the mine car to be unable to operate. In severe cases, it may cause production accidents.

[0024] In order to solve the above problems, in order to prevent the mine car from being unhooked during operation, an anti-slip ring is designed at the connection of the mine car, and a structure is added to the positioning pin to prevent the positioning pin from falling off and causing the mine car to be unable to run.

[0025] Specifically; see attached Figure 1 -Attached Figure 4 , an anti-falling mine car, comprises at least two carriages 100 and a connecting device 200 installed between the two carriages 100, the connecting device 200 comprises a connecting component 1 210 and a connecting component 2 220, the side wall of the connecting component 220 is provided with a connecting protrusion 221, the side wall of the connecting component 1 210 is provided with a connecting groove 211 adapted to the connecting protrusion 221, a positioning pin 400 is installed between the connecting protrusion 221 and the connecting groove 211, and an anti-falling ring 300 is also installed on the upper end of the connecting component 1 210, and an opening for the positioning pin 400 to pass through is formed in the middle of the anti-falling ring 300, and an opening for the positioning pin 400 to pass through is also provided between the connecting component 1 210 and the connecting component 2 220. By passing the positioning pin 400 through the corresponding opening, the connecting component 1 210 and the connecting component 2 220 can be locked and limited, thereby ensuring the stability of the connection between the two and ensuring the normal operation of the mine car.

[0026] A transversely arranged anti-slip channel 310 is opened in the middle position of the side wall of the anti-slip ring 300, an installation channel 311 is opened at the first end of the anti-slip channel 310, and a sunken limiting area 312 is set at the second end. An anti-slip rod 410 adapted to the limiting area 312 is fixed to the side wall of the positioning pin 400.

[0027] During the installation process, the positioning pin 400 is controlled to move along a predetermined trajectory, that is, the anti-slip rod 410 is controlled to move downward through the installation channel 311 first, and then the positioning pin 400 is controlled to rotate to drive the anti-slip rod 410 to move horizontally, and finally the anti-slip rod 410 can enter the limiting area 312. The sinking design of the limiting area 312 here can effectively lock and limit the anti-slip rod 410, thereby ensuring the stability of the anti-slip rod 410; the positioning pin 400 can be locked and limited by the anti-slip rod 410, which can effectively prevent the positioning pin 400 from detaching from the opening.

[0028] The bottom of the anti-slip channel 310 here can be set to a downward inclined structure to facilitate the movement of the anti-slip rod 410 toward the limiting area 312; the limiting area 312 here is sunken, which can limit the anti-slip rod 410, and the bottom of the anti-slip rod 410 can be set to the arc shape shown in the accompanying drawing, which can increase the contact area with the anti-slip rod 410 and ensure the stability of the limitation.

[0029] Preferably, the anti-slip channel 310 and the anti-slip rod 410 are symmetrically arranged in two groups. The symmetrical design of the anti-slip rod 410 here can effectively limit the positioning pin 400 as a whole from both sides, ensuring the stability of the positioning pin 400 in the opening.

[0030] A locking rod 420 is detachably installed on the side wall of the positioning pin 400. The locking rod 420 is staggered with the anti-slip rod 410. By setting the locking rod 420, the positioning pin 400 can be further locked and limited. When the positioning pin 400 is limited, the vertical freedom of the positioning pin 400 can be limited to prevent the positioning pin 400 from driving the anti-slip rod 410 to shake in the limiting area 312, thereby avoiding frequent shaking with excessive amplitude leading to local fatigue damage.

[0031] A threaded hole is provided on the side wall of the positioning pin 400, and the locking rod 420 is threadedly connected to the threaded hole. The locking rod 420 here can be threadedly connected to the positioning pin 400. When the positioning pin 400 needs to be removed, the locking rod 420 is removed first, and then the anti-detachment rod 410 is controlled to move in the opposite path, so that the positioning pin 400 and the anti-detachment rod 410 can be separated as a whole.

[0032] The locking rod 420 includes a threaded connection portion and a locking portion. The locking portion is in the shape of a cone. During the process of continuously rotating the locking rod 420 toward the positioning pin 400, the locking portion in the cone state can gradually approach the inner wall of the limiting area 312, and finally the locking rod 420 is tightly pressed against the limiting area 312, ensuring that the anti-slip rod 410 and the locking rod 420 are tightly pressed against the inner wall of the limiting area 312, thereby ensuring the stability of the overall structure.

[0033] The locking rod 420 here is located on the side of the anti-slip rod 410 away from the connecting component 210, that is, in the installed state, the locking rod 420 is located above the anti-slip rod 410. Through the above-mentioned structural design, when the positioning pin 400 is placed in a stable state, the anti-slip rod 410 is tightly pressed against the bottom of the limiting area 312 under the action of gravity, which facilitates the quick installation of the locking rod 420.

[0034] Elastic buffer pads are fixed to the outer walls of the anti-slip rod 410 and the locking rod 420. The buffer pads can be selected as rubber sleeves, which can reduce the rigid contact between the metal materials while ensuring the tight state.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
