Description

Technical Field

[0001] This utility model relates to the field of mine car pin technology, specifically a mine car with a pin device. Background Technology

[0002] Mining cars are narrow-gauge railway vehicles used in mines to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches. Mining cars are classified into five main categories according to their structure and unloading method: stationary mining cars (material cars, flatbed cars), tipper mining cars, single-sided curved rail side-discharge mining cars, bottom (side) discharge mining cars, and shuttle mining cars.

[0003] When transporting minerals in mining areas, mine cars need to be connected together using components such as pins and chain links to form a train. During use, the pulling force causes wear between the components of the pin assembly, which in turn affects the stable connection of the pins. To address this issue, we propose a mine car with a pin device. Utility Model Content

[0004] The purpose of this utility model is to provide a mining car with a pin device to solve the problem mentioned in the background art that when a mining car is transporting minerals in a mining area, the pulling force will cause wear between the components of the pin assembly, which will affect the stable connection of the pin.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine car with a pin device, comprising a mine car one, a mine car two, and a pin assembly. The mine car one and mine car two are respectively provided with a first fastener and a second fastener, which are connected by the pin assembly. The pin assembly includes a pin sleeve and an inner sleeve. The outer surface of the pin sleeve is provided with uniformly spaced through-hole grooves in an annular shape. The lower end of the inner sleeve is provided with a piston sleeve, and a piston rod is movably inserted into the piston sleeve. A conical block is provided below the piston rod. The conical block is annularly located inside the pin sleeve, and a limiting rod is provided on the outer side of the conical block. A second spring is movably sleeved on the limiting rod. A limiting bolt is threadedly connected to the lower end of the pin sleeve.

[0006] Preferably, the piston rod is located above the limiting bolt, and the piston rod and the limiting bolt are collinear.

[0007] Preferably, the inner sleeve is glued to the inside of the pin sleeve, and the inner side of the inner sleeve and the outer side of the pin sleeve are in contact.

[0008] Preferably, the limiting bolt and the piston rod are in movable contact.

[0009] Preferably, the piston rod is in the shape of an "I" and a spring is movably sleeved on the piston rod.

[0010] Preferably, the spring is located on the outside of the piston sleeve, and the center of the spring and the piston rod are collinear.

[0011] Preferably, the conical block is arranged in a ring outside the limiting bolt, and the conical block and the side wall of the pin sleeve are spaced apart.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This type of pin device for mine cars, after the pin device is inserted into the first and second snap fasteners, rotates the limiting bolt, causing the limiting bolt to insert into the pin sleeve. This provides an upward driving force to the piston rod, compressing the second spring and inserting the piston rod into the piston sleeve. This compresses the gas inside the inner sleeve, causing the inner sleeve to bulge outward and position itself at the through-hole groove. Because there is no restriction, the inner sleeve can bulge outward from the through-hole groove and contact the second snap fastener. This facilitates the insertion of the pin assembly while allowing the insertion assembly to roll into contact with the first and second snap fasteners, effectively reducing the contact friction of the pin assembly and improving the stability of the connection between the mine cars.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figure 1-4This utility model provides a technical solution: a mine car with a pin device, mainly addressing the problem that wear and tear between the components of the pin assembly occurs when the mine car is transporting minerals in a mining area due to the pulling force, thus affecting the stable connection of the pin. The specific solution is as follows: it includes a mine car 101, a mine car 102, and a pin assembly 2. The mine car 101 and the mine car 102 are respectively equipped with a first fastener 3 and a second fastener 4, which are connected by the pin assembly 2.

[0017] Please see Figure 1 , Figure 3 and Figure 4 The pin assembly 2 includes a pin sleeve 21 and an inner sleeve 23. The inner sleeve 23 is glued to the inside of the pin sleeve 21, and the inner surface of the inner sleeve 23 is in contact with the outer surface of the pin sleeve 21. The inner sleeve 23 is made of flexible rubber, which facilitates its deformation. In its initial state, as... Figure 1 As shown, the inner sleeve 23 is not deformed and is square in the main view.

[0018] Furthermore, a circular, uniformly distributed through-hole groove 22 is provided on the outer surface of the pin sleeve 21, wherein the through-hole groove 22 communicates with the interior of the pin sleeve 21. A piston sleeve 24 is provided at the lower end of the inner sleeve 23, and the inner sleeve 23 and the piston sleeve 24 are fixedly installed. A piston rod 25 is movably inserted into the piston sleeve 24, and a tapered block 27 is provided below the piston rod 25.

[0019] Furthermore, the conical block 27 is arranged in a ring inside the pin sleeve 21, and a limiting rod 28 is provided on the outside of the conical block 27. A spring 29 is movably sleeved on the limiting rod 28. Through the setting action of the spring 29, the limiting rod 28 can be retracted into the pin sleeve 21 in the initial state, thereby facilitating the insertion of the pin assembly 2.

[0020] Furthermore, a limiting bolt 20 is threadedly connected to the lower end of the pin sleeve 21. The piston rod 25 is located above the limiting bolt 20, and the piston rod 25 and the limiting bolt 20 are collinear. The limiting bolt 20 and the piston rod 25 are in movable contact. After rotating the limiting bolt 20, it can be inserted into the pin sleeve 21, thereby providing an upward driving force to the piston rod 25, compressing the second spring 29, and inserting the piston rod 25 into the piston sleeve 24, compressing the gas inside the inner sleeve 23, causing the inner sleeve 23 to bulge outward and be positioned at the through-hole groove 22. Due to the lack of restriction, the inner sleeve 23 can bulge outward from the through-hole groove 22 and contact the second snap fastener 4, facilitating the insertion of the pin assembly 2 while allowing the pin assembly 2 and the second snap fastener 4 and the first snap fastener 3 to roll in contact, effectively reducing the contact friction of the pin assembly 2 and preventing loosening during the connection process.

[0021] In this embodiment, the piston rod 25 is I-shaped, and a spring 26 is movably sleeved on the piston rod 25. The spring 26 is located on the outside of the piston sleeve 24, and the centers of the spring 26 and the piston rod 25 are collinear. A conical block 27 is annularly located on the outside of the limiting bolt 20, and the conical block 27 and the side wall of the pin sleeve 21 are spaced apart. The elastic action of the spring 26 ensures that the piston rod 25 remains at the lower end of the piston sleeve 24.

[0022] It is worth noting that the inner sleeve 23 is filled with gas. When the piston rod 25 is inserted into the piston sleeve 24, the gas is compressed, causing the inner sleeve 23 to bulge outward and be placed at the through hole groove 22. This allows the pin assembly 2 and the second and third fasteners to roll into contact, effectively reducing the contact friction of the pin assembly 2 and preventing loosening of the pin assembly 2 during the connection process.

[0023] Working principle: This type of pin device used in mine cars, in its initial state, such as... Figure 3 As shown, in this state, the insertion of the pin assembly 2 is convenient. After the pin assembly 2 is inserted into the snap fastener 3 and snap fastener 4, the limiting bolt 20 can be inserted into the pin sleeve 21 by rotating the limiting bolt 20. This provides an upward driving force to the piston rod 25, compressing the spring 29 and inserting the piston rod 25 into the piston sleeve 24. This compresses the gas inside the inner sleeve 23, causing the inner sleeve 23 to bulge outward and be positioned at the through-hole groove 22. Since there is no restriction, the inner sleeve 23 can bulge outward from the through-hole groove 22 and contact the snap fastener 4. This facilitates the insertion of the pin assembly 2 while allowing the pin assembly 2 to roll into contact with the snap fastener 4 and snap fastener 3, effectively reducing the contact friction of the pin assembly 2 and improving the stability of the connection between the mine car and the mine car.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
