Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connecting rods for mining cars, in particular to an anti-collision hard connecting rod for mining cars. Background Art
[0002] Mine cars are narrow-gauge railway vehicles used to transport bulk materials such as coal, ore, and waste rock in mines. They are generally pulled by a locomotive or winch. Mine cars are divided into five main categories based on their structure and unloading method: fixed mine cars (material cars, flatbed cars), dump mine cars, single-side curved track side-dump mine cars, bottom (side) dump mine cars, and shuttle mine cars.
[0003] Connecting rods are required when connecting mine cars, but some existing connecting rods for mine cars have relatively simple structures and do not have a buffering effect. When the mine cars collide, the connecting rods cause greater damage to the mine cars. Therefore, the present application provides an anti-collision hard connecting rod for mine cars to meet the needs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an anti-collision hard connecting rod for a mine car to solve the problem that the existing connecting rods for some mine cars have a relatively simple structure and do not have a buffering effect. When the mine car collides, the connecting rod causes great damage to the mine car.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] A collision-proof hard connecting rod for a mining car comprises: a first steel sleeve and a second steel sleeve, wherein a buffer mechanism is provided inside the first steel sleeve and the second steel sleeve, and the buffer mechanism comprises a buffer component and a connecting component, wherein the buffer component is located inside the first steel sleeve or the second steel sleeve, and the connecting component is located outside the first steel sleeve or the second steel sleeve.
[0007] In some examples, the buffer assembly includes a mounting block, which is fixedly connected to the inside of the first steel sleeve or the second steel sleeve, a first buffer spring is provided on the side of the mounting block away from the outside of the first steel sleeve or the second steel sleeve, a connecting block is provided on the side of the first buffer spring away from the mounting block, a second buffer spring is provided on the side of the connecting block away from the first buffer spring, and buffer pads are provided between the first buffer spring and the second buffer spring and the connecting block, and the buffer pads are made of high molecular polyester material.
[0008] In some examples, a movable block is provided at one end of the second buffer spring away from the connecting block. The movable block is movably connected to the first steel sleeve or the second steel sleeve, and a movable ring is sleeved on the outside of the movable block.
[0009] In some examples, the first buffer spring and the second buffer spring are each equipped with a damper.
[0010] In some examples, the connecting assembly includes a connecting rod, which is fixedly connected to the side of the movable block away from the second buffer spring. A rotating rod is provided inside the connecting rod, and the rotating rod is rotatably connected to the connecting rod. Side blocks are provided at both ends of the rotating rod, and positioning blocks are provided on the sides of the side blocks. A positioning hole is opened in the middle of the positioning block.
[0011] In some examples, a limit rod is provided on the surface of the connecting rod, and a plurality of limit blocks are provided on the outer surface of the side block, and the limit blocks are matched and connected with the limit rod.
[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. The two buffer assemblies are respectively placed in the first steel sleeve and the second steel sleeve, and the mounting blocks of the two buffer assemblies are respectively welded to the first steel sleeve and the second steel sleeve, and then the first steel sleeve and the second steel sleeve are welded to form a whole device. The device is connected to the mine car through the positioning block and the positioning hole, so that the mine car is connected. When the mine car collides, the positioning block transmits the collision force to the connecting rod and the movable block, so that the movable block moves inside the steel sleeve and squeezes the second buffer spring, so that the second buffer spring and the damper of the second buffer spring reduce the impact force. The remaining impact force is secondary reduced by the first buffer spring and the damper of the first buffer spring, thereby avoiding the impact of the impact force on the mine car and improving the practicality of the device.
[0015] Second, the positioning block and the side block can be rotated by the provided rotating rod, and the rotation angle of the positioning block and the side block can be limited by the limit block and the limit rod, thereby making the installation between the connecting assembly and the mine car more convenient and making the impact force transmission of the device when the mine car collides more smooth.

[0029] What needs to be further explained in this embodiment is that the buffer assembly includes a mounting block 31, which is fixedly connected to the inside of the first steel sleeve 1 or the second steel sleeve 2. By placing the two buffer assemblies in the first steel sleeve 1 and the second steel sleeve 2 respectively, and welding the mounting blocks 31 of the two buffer assemblies to the first steel sleeve 1 and the second steel sleeve 2 respectively, and then welding the first steel sleeve 1 and the second steel sleeve 2, the device is formed into a whole. A first buffer spring 32 is provided on the side of the mounting block 31 away from the outside of the first steel sleeve 1 or the second steel sleeve 2, a connecting block 34 is provided on the side of the first buffer spring 32 away from the mounting block 31, and a second buffer spring 35 is provided on the side of the connecting block 34 away from the first buffer spring 32.

The first buffer spring 32 and the second buffer spring 35 are both equipped with dampers. The device is connected to the mine car through the positioning block 3702 and the positioning hole 3703, thereby connecting the mine car. When the mine car collides, the positioning block 3702 transfers the collision force to the connecting rod 3701 and the movable block 36, so that the movable block 36 moves inside the steel sleeve and squeezes the second buffer spring 35, so that the second buffer spring 35 and the damper of the second buffer spring 35 reduce the impact force.

[0034] The two buffer components are placed in the first steel sleeve 1 and the second steel sleeve 2 respectively, and the mounting blocks 31 of the two buffer components are welded between the first steel sleeve 1 and the second steel sleeve 2 respectively, and then the first steel sleeve 1 and the second steel sleeve 2 are welded together to form a whole device. The device is connected to the mine car through the positioning block 3702 and the positioning hole 3703, so that the mine car is connected.
