[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-2 This utility model provides a technical solution:

[0023] A charging trolley for tunnel excavation includes a frame 1. A track 2 is connected to the lower end of the frame 1. The track 2 is adaptable to the harsh road environment inside the tunnel, and the tracked transmission structure enables rapid movement, meeting the need for rapid evacuation of equipment during blasting. A first fixed platform 3 is connected to the frame 1. The first fixed platform 3 is a fixed structure. A first pull-out platform 4 is slidably connected to the first fixed platform 3. A first folding platform 5 is rotatably connected to the first pull-out platform 4. A ladder platform 11 is connected to the upper end of the frame 1. Construction personnel can move to the ladder platform 11 using the end lifting platform 10. Construction personnel can clean the tunnel ceiling from the ladder platform 11 to prevent falling debris and safety accidents. A lifting mechanism is connected to the frame 1 to lift and lower the construction personnel.

[0024] Specifically, such as Figure 2 As shown, a top protective canopy 9 is slidably connected to the walkway platform 11. The top protective canopy 9 can move along the walkway platform 11 and can play a good protective role.

[0025] Specifically, such as Figure 2 As shown, a hydraulic lift 15 is connected to the first fixed platform 3, and a second lifting platform 6 is connected to the upper end of the hydraulic lift 15. By controlling the hydraulic lift 15, the second lifting platform 6 can be raised to a certain height.

[0026] Specifically, such as Figure 1 As shown, a second-layer pull-out platform 7 is slidably connected to the second-layer lifting platform 6, and a second-layer folding platform 8 is rotatably connected to one end of the second-layer pull-out platform 7. The segmented pull-out design can improve the extensibility of the work platform, and the liftable second-layer lifting platform 6 can avoid the wind belts in the tunnel when the equipment moves, thus improving the adaptability of the equipment to various working environments.

[0027] Specifically, such as Figure 1 As shown, the first-layer folding platform 5 is connected to the first-layer platform plug-in guardrail 13, and the second-layer folding platform 8 is connected to the second-layer platform plug-in guardrail 12. The installation of guardrails can improve the safety of operation.

[0028] Specifically, such as Figure 2 As shown, an escalator 14 is connected to the first fixed platform 3, which facilitates the movement of construction workers to the first fixed platform 3.

[0029] Specifically, such as Figure 2 As shown, the lifting mechanism includes an end lifting platform 10, and a motor reducer 16 is connected to the frame 1. The end lifting platform 10 is connected to the motor reducer 16 via a chain 17. The end lifting platform 10 is slidably connected to the frame 1. The motor reducer 16 can quickly drive the end lifting platform 10 to lift.

[0030] In summary, the charging trolley for tunnel excavation provided in this embodiment allows construction workers to move to the first fixed platform 3 via the ladder 14 when drilling holes, charging explosives, and hanging mesh on the tunnel outline during face excavation. The first pull-out platform 4 and the first folding platform 5 improve the extensibility of the first fixed platform 3, making it easier for construction workers to access the tunnel wall and facilitate construction on uneven areas after face blasting.

[0031] Construction workers can also move to the second-level lifting platform 6 and lift the workers to a certain height by controlling the hydraulic lift 15 to carry out the installation of the hanging mesh at a higher position in the tunnel. The second-level lifting platform 6 also adopts a segmented pull-out design, which increases the working range.

[0032] Construction personnel can move directly to the end lifting platform 10. The control motor reducer 16, in conjunction with the chain 17, drives the construction personnel to move upward. The walking track 2 allows the construction personnel to approach one end of the tunnel. The track structure can adapt to complex excavation surfaces and can retreat from the blasting face after the explosives are loaded, ensuring the safety of equipment and personnel. The space under the frame 1 is open, allowing other vehicles or equipment to pass.

[0033] The top is equipped with a longitudinally movable top protective canopy 9, which can be moved away to provide space during top construction and can prevent falling rocks and ensure construction safety at other times. The protective net on it is diamond-shaped.

[0034] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
