Description

Technical Field

[0001] The utility model relates to the technical field of gold mine transport vehicles, in particular to a stabilizing structure for a mine vehicle. Background Art

[0002] During the gold mining process, gold ore needs to be transported by rail trolleys, which are gold mine carts. Gold mine carts are the main tools for transporting mined ore from underground to the ground. Their efficient transportation capacity directly affects the production efficiency of gold mines.

[0003] At present, the Chinese utility model with the announcement number: CN213801629U discloses a transportation device for gold mining. This utility model belongs to the field of transportation equipment for gold mining, especially a transportation device for gold mining. In view of the problems that the existing rail trolley for transporting gold ore has poor shock absorption performance, which causes the gold ore to easily fall out of the transport container due to vibration, has poor practicality, and the operations required for disassembling and assembling the transport container are cumbersome, inconvenient to replace the transport container, and poor convenience, the following solution is proposed, which includes a base, a rail wheel is installed at the bottom of the base, and a shock-absorbing box is fixed on the top wall of the base. The four corners of the top wall of the shock-absorbing box are provided with movable holes, and the gaps in the movable holes are fitted with support columns. The bottom ends of the four support columns extend to the interior of the shock-absorbing box and are fixedly connected with shock-absorbing plates. The utility model has a novel design, strong shock absorption performance, and less vibration during transportation, which can prevent the gold ore from falling out of the transport container due to vibration. It is highly practical, convenient to disassemble and assemble the transport container, convenient to replace the transport container, and highly convenient.

[0004] When existing mine cars are used to transport gold ore, their tunnels are narrow, the terrain is undulating, and the transportation route is long, which inevitably causes large vibrations. As a result, the ore is easily dropped from the mine car due to the vibration, and the fallen fine ore and particles fall onto the surface of the mine car track, which affects the flatness of the mine car track, and then causes the mine car wheels to vibrate when passing. When the vibration amplitude is too large, the mine car will be at risk of overturning. At the same time, the ore powder and slag adhere to the wheels, which will change the shape and weight distribution of the wheels, affect the rolling performance of the wheels, and make the mine car unstable when moving. This will not only reduce transportation efficiency, but also increase safety hazards. Therefore, a stabilizing structure for a mine car is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a stabilizing structure for a mine car, which aims to solve the problem that the existing mine cars, when used to transport gold ore, inevitably experience large vibrations due to their narrow tunnels, uneven terrain, and long transportation routes, which causes the ore to easily fall from the mine car due to the vibrations. The fallen fine ore and particles fall onto the surface of the mine car track, which affects the flatness of the mine car track and further causes the mine car wheels to vibrate when passing. When the vibration amplitude is too large, the mine car will be at risk of overturning. At the same time, the ore powder slag adhering to the wheels will change the shape and weight distribution of the wheels, affecting the rolling performance of the wheels, making the mine car unstable when moving, which not only reduces transportation efficiency but also increases safety hazards.

[0014] Preferably, a torsion sleeve is fixedly connected to the top of the screw rod, and the torsion sleeve is U-shaped.

[0015] In the technical solution of the utility model, a track cleaning assembly is provided. When the mine car is traveling on the track, the track cleaning assembly is located at the front and rear sides of the mine car body and contacts the track surface. As the mine car moves, the fine ore and particles on the track are scraped or swept to both sides of the track, keeping the track surface flat, thereby reducing the vibration generated when the mine car wheels pass, reducing the risk of rollover, and greatly improving the safety during transportation. The scraper wheel assembly is also installed at the front and rear sides of the mine car body, close to the wheel position. When the wheel rotates, the scraper wheel assembly contacts the wheel surface and scrapes off the ore powder and slag adhered to the wheel.

[0028] The utility model provides a stabilizing structure for a mine car, which aims to solve the problem that the existing mine car, when used to transport gold ore, inevitably experiences large vibrations due to its narrow tunnels, uneven terrain, and long transportation routes, causing the ore to easily fall from the mine car due to the vibrations. The fallen fine ore and particles fall onto the surface of the mine car track, which affects the flatness of the mine car track and further causes the mine car wheels to vibrate when passing. When the vibration amplitude is too large, the mine car will be at risk of overturning. At the same time, the ore powder residue adhering to the wheels will change the shape and weight distribution of the wheels, affecting the rolling performance of the wheels, making the mine car unstable when moving, which not only reduces transportation efficiency but also increases safety hazards.

[0029] like Figure 1-5 As shown, an embodiment of the present invention provides a stabilizing structure for a mine car, comprising a mine car body 1, wheels 2 are provided on the front and rear sides of both sides of the mine car body 1, track cleaning assemblies 3 are provided on the front and rear sides of both sides of the mine car body 1, scraper assemblies 4 are provided on the front and rear sides of both sides of the mine car body 1, and stabilizing support assemblies 5 are provided on both sides of the mine car body 1;

[0030] The stabilizing assembly 5 includes a fixed block 501 bolted to both sides of the mine car body 1 respectively, the bottom of the fixed block 501 is bolted to an upper sleeve 502, the interior of the upper sleeve 502 is torsionally connected to a hydraulic spring rod 503, the bottom of the hydraulic spring rod 503 is torsionally connected to a lower sleeve 504, the bottom of the lower sleeve 504 is bolted to a frame 505, and the interior of the frame 505 is rotatably connected to a stabilizing shaft wheel 506.

[0031] In the technical solution of the present invention, by arranging the track cleaning assembly 3, the scraper assembly 4 and the stabilizing assembly 5, when the mine car is traveling on the track, the track cleaning assembly 3 is located on the front and rear sides of the mine car body 1 on both sides, in contact with the track surface, and as the mine car moves, the fine ore and particles on the track are scraped or swept to both sides of the track, keeping the track surface flat, thereby reducing the vibration generated when the mine car wheels 2 pass, reducing the risk of rollover, and greatly improving the safety during transportation. At the same time, the scraper assembly 4 is also installed on the front and rear sides of the mine car body 1 on both sides, close to the wheel 2. When the wheel 2 rotates, the scraper assembly 4 contacts the surface of the wheel 2 and scrapes off the ore powder and slag adhered to the wheel 2. The scraper assembly 4 can be designed according to the shape and size of the wheel 2 to ensure that it can be fully The powder and residue on the surface of the wheel 2 are cleaned to prevent the shape and weight distribution of the wheel 2 from changing, thereby ensuring the stable rolling performance of the wheel 2 and further enhancing the safety of the mine car's travel. In addition, the upper sleeve 502 is fixed to both sides of the mine car body 1 through the fixed block 501 in the stabilizing assembly 5, and the hydraulic spring rod 503 can automatically adjust the length according to the changes in the terrain to play a role in buffering and shock absorption. The lower sleeve 504 is connected to the frame 505, and the stabilizing shaft wheel 506 in the frame 505 is in contact with the ground during the travel of the mine car to provide additional support force. When the mine car passes through an undulating road surface, the hydraulic spring rod 503 and the stabilizing shaft wheel 506 can work together to maintain the stability of the mine car, reduce shaking and tilting, and thus effectively prevent the mine car from shaking too much and rolling over.

This ensures stable rolling performance of the wheels 2, making the mine car move more smoothly and improving transportation efficiency and safety.

[0035] Please refer to Figure 4 The bottom of the scraper 402 is curved and made of a rubber material. In this embodiment, the curved bottom of the scraper 402 can better fit the surface of the wheel 2, increasing the contact area with the wheel 2 and improving the scraping effect of the powder residue. The rubber material is soft and elastic, and will not scratch the wheel 2 during the scraping process, thus protecting the wheel 2 surface and extending the service life of the wheel 2. At the same time, the rubber material also has a certain degree of wear resistance and can withstand long-term friction.

[0036] Also, please refer to Figure 1 The front and rear sides of the mine car body 1 are bolted with push-pull handles 6, which have a rotation function.
