[0002] Shuttle cars, with their advantages of continuous unloading, large carrying capacity, high unloading efficiency, and no ore or slag settling at the bottom, have significant advantages in tunnel engineering projects with tight schedules, high slag removal efficiency, and low transportation costs. However, traditional shuttle cars lack loading and hoisting systems. In the later stages of tunnel construction, the surface soil of the track can only be removed manually, and then the rails and sleepers are dismantled one by one and transported out of the tunnel. This construction process makes it difficult to fully utilize the advantages of shuttle cars and results in low safety for construction workers, high labor intensity, low construction efficiency, and affects the overall project progress. Summary of the Invention

[0003] The purpose of this invention is to provide a shuttle mine car with a remote-controlled loading and hoisting system and its construction method to solve the problems existing in the prior art.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-2 As shown, the present invention provides a shuttle mine car with a remote-controlled loading and hoisting system, including...

[0026] A shuttle car module, comprising a shuttle car body 10 that moves along the tunnel;

[0027] The mini excavator loading system is located at the rear of the shuttle car body 10. The mini excavator loading system includes an excavator boom 6 and a loading system hydraulic power station 9. The excavator boom 6 is installed on a pre-reserved base at the rear of the shuttle car body 10 and is used to transfer excavated soil into the shuttle car body 10. The loading system hydraulic power station 9 is connected to the excavator boom 6 through hydraulic pipelines.

[0028] The hoisting system consists of two sets of hoisting systems arranged on both sides of the shuttle car body 10. The hoisting system includes a cantilever support 2, a telescopic boom 3, and a rail bracket 8. The cantilever support 2 is supported on the outer wall of the shuttle car body 10. The telescopic boom 3 extends and retracts linearly within the cantilever support 2 under the drive of a gear reducer. The outer end of the telescopic boom 3 is equipped with a boom hook 4. An electric hoist is connected to the boom hook 4 via a wire rope. The boom hook 4 is used to hoist the rail 5 and place the rail 5 on the rail bracket 8 on the shuttle car body 10 as the telescopic boom 3 moves.

[0029] Specifically, two hoisting systems are arranged on both sides of the shuttle car body 10. The fixed ends 1 of the booms on both sides are connected to the front of the shuttle car body 10 by flanges. The cantilever support 2 is supported on the outer wall of the middle position of the shuttle car body 10, and the cantilever support 2 is connected to the shuttle car body 10 by flanges. The telescopic boom 3 can extend and retract linearly in the cantilever support 2 under the drive of the gear reducer. The boom hook 4 moves linearly with the telescopic boom 3. The electric hoist is connected to the boom hook 4 through a wire rope. The steel rail 5 to be hoisted is located at the rear of the shuttle car body 10. The steel rail 5 can be hoisted and placed on the rail bracket 8 by the hoisting system.

[0030] A mini excavator loading system is installed at the rear of the shuttle car body 10. Figure 2The excavator boom 6 is equipped with an excavator slewing bearing flange 7 at its base. The excavator slewing bearing flange 7 mounts the excavator boom 6 onto a pre-reserved base at the rear of the shuttle car body 10. The excavator boom 6 has slewing, telescopic, and limiting functions (the implementation of each function of the excavator boom 6 is based on existing mature technology and will not be elaborated further here). The loading system hydraulic power station 9 is placed at the bottom of the middle position of the shuttle car body 10. The loading system hydraulic power station 9 is connected to the shuttle car body 10 by a flange. The top end cap of the loading system hydraulic power station 9 is parallel to the bottom slope of the shuttle car body 10.

[0031] The mini excavator loading system and hoisting system are operated in stages, with the latter controlled separately by wireless remote controllers. In the final stage of tunnel construction, the mini excavator loading system first transfers the excavated soil into the shuttle mine car body 10. After loading, the excavator boom 6 is adjusted to be horizontal with the tunnel axis. The hoisting system is then activated, and the telescopic booms 3 on both sides and the boom hooks 4 are controlled by wireless remote controllers to hoist the rails 5 into the rail brackets 8. After hoisting, the telescopic booms 3 are retracted.

[0032] A construction method for a shuttle mine car with a remote-controlled loading and hoisting system includes the following steps:

[0033] The shuttle mine car body 10 is driven to the bottom of the tunnel. The loading system of the mini excavator is controlled by remote control. The hydraulic power station 9 of the loading system provides driving force to the excavator arm 6 through hydraulic pipelines. The excavator arm 6 moves to transport the slag from the tunnel surface into the shuttle mine car body 10. At the same time, the hoisting system is controlled by remote control. The gear reducer is turned on, and the telescopic booms 3 on both sides of the shuttle mine car body 10 extend from the cantilever support 2 under the drive of the gear reducer. The electric hoist drives the boom hook 4 at the end of the wire rope to move up and down. The boom hook 4 at the end of the telescopic boom 3 lifts the rail 5. Then, the telescopic boom 3 is retracted under the drive of the gear reducer. When the rail 5 moves with the telescopic boom 3 to the rear position of the shuttle mine car body 10, the electric hoist drives the boom hook 4 at the end of the wire rope to lower and place the rail 5 on the rail bracket 8.

[0034] The shuttle mine car of the present invention, which has a remote-controlled loading and hoisting system, has the following advantages:

[0035] 1. The rear of the shuttle mine car body 10 integrates the excavator arm 6, and the corresponding loading system hydraulic power station 9 is integrated at the bottom of the middle position of the shuttle mine car body 10, cleverly integrating the excavator loading system onto the shuttle mine car.

[0036] 2. The top end cover of the hydraulic power station 9 of the loading system adopts an inclined arrangement. The inclination angle is consistent with the inclination angle of the shuttle mine car, which innovatively achieves a high degree of integration between the hydraulic power station 9 of the loading system and the shuttle mine car body 10.

[0037] 3. The multi-functional shuttle mine car loading system and hoisting system involved are all remotely controlled; the loading system, hoisting system and shuttle mine car are highly integrated, which greatly improves the efficiency of tunnel excavation.

[0038] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
