Description

A type of track-mounted car stop for mining Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a mining track-type vehicle stopper. Background Technology

[0002] A cage is a hoisting container used for the safe hoisting of materials, equipment, and personnel in a vertical shaft. Car arresters are crucial devices in the hoisting system, used for transporting ore, materials, and various equipment and facilities by mine cars. It is essential to ensure that mine cars or flatbed cars cannot move along the tracks inside the cage. Therefore, safe and reliable car arresters must be installed at both ends of the tracks inside the cage. These arresters must be safe, reliable, convenient, quick, and easy to use.

[0003] In actual use, iron blocks or grooves in the track are generally used to ensure the reliability of vehicle blocking. However, the process of creating grooves in the track is time-consuming and laborious, and the use of iron blocks to block vehicles results in a large impact from rigid collisions, which poses certain safety hazards and can easily lead to safety accidents. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a mine track-type vehicle stopper, which solves the problems of time-consuming and labor-intensive installation and lack of safety of existing vehicle stoppers.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A mine track-type car stopper includes a track, a support base plate installed on the side of the track by fasteners, a support side plate installed on the side perpendicular to the support base plate, a main shaft movably inserted into the support side plate, a limit ring provided after a crank is movably sleeved on one end of the main shaft, and an anti-detachment component provided on the other end of the main shaft, a car-blocking block provided on the side of the crank near the anti-detachment component, and a sliding groove adapted to the top of the track is opened at the bottom of the crank and the car-blocking block.

[0007] A buffer spring is movably sleeved on one end of the main shaft where the anti-detachment component is installed. One end of the buffer spring abuts against the side of the support side plate, and the other end of the buffer spring rests against the anti-detachment component.

[0008] The car-sheltering section of the car-sheltering block is an arc shape adapted to the mine car wheel.

[0009] A handle is provided on the back of the crank.

[0010] The fasteners include fixing bolts and fixing nuts. The fixing bolts pass through the fixing base plate and the side of the track in sequence and are then fitted with fixing nuts.

[0011] The fastener also includes a washer, and the fastening bolt is fitted with the washer and then the fixing nut is installed.

[0012] One end of the spindle is provided with an external thread for mounting the anti-detachment component. The anti-detachment component includes a retaining ring and an anti-detachment nut. After the retaining ring is sleeved on the spindle, the anti-detachment nut is fitted onto the external thread of the spindle.

[0013] The anti-loosening nut is a slotted nut, and a positioning hole is provided on the main shaft at any position corresponding to the slot of the slotted nut. A cotter pin is installed between the slot of the slotted nut and the positioning hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: a mine track-type car stop.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a buffer spring movably sleeved at one end of the main shaft with an anti-detachment component. When the mine car wheel impacts the car-stopping block, the buffer spring effectively absorbs the impact force. Compared to traditional methods using iron blocks or grooves in the track, the buffer spring can elastically compress according to the magnitude of the impact force from the mine car, transforming rigid collisions into flexible buffering. This not only reduces the thrust of the mine car wheel but also significantly reduces damage to the mine car, the car-stopping block itself, and the track, extending the service life of the equipment and effectively reducing the probability of safety accidents.

[0017] 2. A handle is installed on the back of the crank, allowing operators to easily turn the crank to open and close the car stop by simply holding the handle. This design changes the complex and labor-intensive operation method in the previous loading and unloading process, greatly reducing labor intensity, shortening the loading and unloading time of mine cars, and significantly improving the production efficiency of mining operations;

[0018] 3. One end of the main shaft where the anti-detachment component is installed has an external thread. The anti-detachment component includes a retaining ring and an anti-detachment nut. After the retaining ring is fitted onto the main shaft, the anti-detachment nut is fitted onto the external thread of the main shaft. The anti-detachment nut is a slotted nut, which engages with the positioning hole on the main shaft through a cotter pin. The multiple anti-detachment structures work together to form a robust anti-detachment system. Compared with the single anti-detachment design in existing vehicle stoppers, it can more effectively prevent the main shaft from falling off the support side plate. Even in the complex working environment of the mine and under frequent use, it can ensure the stability and reliability of the overall structure of the vehicle stopper, further ensuring the safety of mine transportation operations.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] A mine track-type car stopper includes a track 1. A support base plate 3 is mounted on the side of the track 1 via fasteners 2. A support side plate 4 is mounted on the side perpendicular to the support base plate 3. A main shaft 5 is movably inserted into the support side plate 4. A crank 6 is movably fitted onto one end of the main shaft 5, and a limit ring 7 is provided thereon. An anti-detachment component 8 is provided at the other end of the main shaft 5. A car-shielding block 9 is provided on the side of the crank 6 near the anti-detachment component 8. A sliding groove 10 adapted to the top of the track 1 is formed at the bottom of the crank 6 and the car-shielding block 9. A buffer spring 11 is movably fitted onto the end of the main shaft 5 where the anti-detachment component 8 is located. One end of the buffer spring 11 abuts against the side of the support side plate 4, and the other end of the buffer spring 11 abuts against the anti-detachment component 8. The car-shielding part 901 of the car-shielding block 9 is arc-shaped and adapted to the mine car wheel. A handle 12 is provided on the back of the crank 6. The fastener 2 includes a fixing bolt 201 and a fixing nut 202. The fixing bolt 201 passes through the support base plate 3 and the side of the track 1 in sequence before the fixing nut 202 is installed. The fastener 2 also includes a washer 203. The fixing bolt 201 is fitted with the washer 203 before the fixing nut 202 is installed. One end of the main shaft 5 that is equipped with the anti-detachment component 8 has an external thread 13. The anti-detachment component 8 includes a retaining ring 801 and an anti-detachment nut 802. The retaining ring 801 is fitted onto the main shaft 5, and the anti-detachment nut 802 is installed on the external thread 13 of the main shaft 5. The anti-detachment nut 802 is a slotted nut. A positioning hole is opened on the main shaft 5 at any position corresponding to the slot of the slotted nut. A cotter pin 803 is installed between the slot of the slotted nut and the positioning hole.

[0025] When using:

[0026] When a mine car is about to enter the cage or needs to stop at a designated location, the operator grasps the handle 12 on the back of crank 6 and rotates crank 6, causing crank 6 to rotate the car shield block 9, so that the sliding groove 10 at its bottom engages with the top of the rail 1. At this time, the car shield block 9 is in a ready-to-work state. When the mine car wheel moves to the car shield block 9, the mine car wheel applies an external force to the car shield block 9. The car shield block 9 transmits this torque to crank 6, crank 6 drives the main shaft 5 to slide on the support side plate 4, thereby compressing the buffer spring 11. The compression of the buffer spring 11 effectively reduces the thrust of the mine car wheel, achieving safe and reliable blocking of the mine car.

[0027] When the mine car needs to continue passing, the operator holds handle 12 and turns crank 6 counterclockwise to disengage the car cover block 9 from the mine car wheels, allowing the mine car to pass smoothly.

[0028] Through the above installation and usage process, the mine track-type car stopper described in this utility model can effectively achieve safe and reliable blocking of mine cars and convenient operation, meeting the actual needs of mine operations.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
