A ladder for climbing to the top of the carriage is fixedly installed at one end of the carriage. A lifting guardrail is installed on the top of the carriage to prevent people from falling. A liftable tool tray is installed on the lifting guardrail.

[0005] As a further improvement, the lifting guardrail includes a horizontally set fence, with multiple vertically extending inner tubes fixedly installed at the bottom of the fence, and an outer tube corresponding to each of the inner tubes fixedly installed at the top of the carriage. The inner tubes are vertically slidably installed inside the outer tubes, and a first hydraulic cylinder for driving the fence to rise and fall is also installed at the top of the carriage.

[0006] As a further improvement, the multiple outer tubes are arranged in a rectangular pattern along the top edge of the carriage, and a crossbeam is fixedly installed between the upper ends of two adjacent outer tubes.

[0007] As a further improvement, a lifting adjustment assembly is provided between the tool tray and the lifting guardrail. The lifting adjustment assembly includes two support rods arranged in an X-shape, namely a first rod and a second rod, with the middle portions of the first rod and the second rod hinged to each other. A slider is horizontally slidably mounted on the tool tray. The lower end of the first rod is hinged to the lifting guardrail, and the upper end is hinged to the slider. A second hydraulic cylinder is mounted on the lifting guardrail. The piston rod of the second hydraulic cylinder extends horizontally. The upper end of the second rod is hinged to the tool tray, and the lower end is hinged to the piston rod of the second hydraulic cylinder. The distance between the lower ends of the first rod and the lower ends of the second rod is adjusted by extending and retracting the second hydraulic cylinder.

[0008] As a further improvement, a laterally extending support beam is fixedly installed inside the carriage, and the support beam is supported on the inner side of the top wall of the carriage.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1 to 5 As shown, the self-made special platform tool cart includes a carriage 1, which has a seating space to facilitate the carrying of workers. Carriage doors 2 are also slidably installed on the left and right sides of carriage 1. Wheel sets 3 are installed at the bottom of carriage 1, which cooperate with the rails in the tunnel to facilitate the movement of carriage 1. In addition, a braking assembly is also provided at the bottom of carriage 1.

[0015] like Figure 2 As shown, a ladder 4 for climbing to the top of the carriage 1 is welded to the rear end of the top. A lifting guardrail 5 is installed on the top of the carriage 1 to prevent personnel from falling, and a liftable tool tray 6 is mounted on the lifting guardrail 5. When inspecting and maintaining the tunnel facilities, workers can climb to the top of the carriage 1 via the ladder 4 to perform work at height. The lifting guardrail 5 prevents workers from falling from the top of the carriage 1, improving work safety. In addition, the top of the carriage 1 can also transport tools and materials used for facility inspection and maintenance, eliminating the need for workers to move materials during inspection and maintenance, thus improving work efficiency.

[0016] like Figure 3 As shown, the lifting guardrail 5 includes a horizontally arranged fence 7, which is a rectangular frame. The shape of the fence 7 matches the shape of the top of the carriage 1. Multiple vertically extending inner tubes 8 are welded to the bottom of the fence 7, and outer tubes 9, corresponding one-to-one with the inner tubes 8, are welded to the top of the carriage 1. The inner tubes 8 are vertically slidably installed inside the outer tubes 9 to adjust the height of the fence 7. In this embodiment, the multiple outer tubes 9 are rectangularly distributed along the top edge of the carriage 1, and a crossbeam 10 is welded between the upper ends of two adjacent outer tubes 9. A first hydraulic cylinder 11 for lifting and lowering the fence 7 is also installed on the top of the carriage 1. The cylinder body of the first hydraulic cylinder 11 is fixedly installed on the top of the carriage 1 with bolts, and the piston rod of the first hydraulic cylinder 11 passes upward through the crossbeam 10 and is fixedly installed on the fence 7 with bolts. In the initial state, the first hydraulic cylinder 11 is in a retracted state and the railing 7 is in a lowered state, thereby improving the stability of the carriage 1 when it moves, and also making it easier for workers to climb over the railing 7 to the top of the carriage 1. When carrying out maintenance work, after the workers climb to the top of the carriage 1, the first hydraulic cylinder 11 extends and drives the railing 7 to rise, thereby the railing 7 plays a protective role and effectively prevents the workers from falling from the top of the carriage 1.

[0017] like Figure 5 As shown, a lifting adjustment component is provided between the tool tray 6 and the lifting guardrail 5. In this embodiment, a set of lifting adjustment components is provided between the left and right ends of the tool tray 6 and the lifting guardrail 5, thereby improving the stability of the lifting of the tool tray 6. The lifting and adjusting assembly includes two support rods arranged in an X-shape. The two support rods are a first rod 12 and a second rod 13. The middle parts of the first rod 12 and the middle parts of the second rod 13 are hinged to each other by a laterally extending pin 14. The left and right ends of the tool tray 6 are respectively fixed with horizontally extending slide rails 15. A slider 16 is slidably installed in the slide rails 15. A laterally extending connecting shaft 17 is installed on the side of the slider 16 away from the tool tray 6. The lower end of the first rod 12 is tilted backward and hinged to the guardrail 7, and the upper end is tilted forward and hinged to the connecting shaft 17. The left and right sides of the tool tray 6 are respectively fixed with bolts to the guardrails 7. The piston rod of the second hydraulic cylinder 18 extends horizontally backward. A laterally extending mounting shaft 19 is installed on the piston rod of the second hydraulic cylinder 18. The upper end of the second rod 13 is tilted backward and hinged to the tool tray 6, and the lower end is tilted forward and hinged to the corresponding mounting shaft 19.

[0018] The distance between the lower ends of the first rod 12 and the second rod 13 is adjusted by extending and retracting the second hydraulic cylinder 18. Specifically, when the second hydraulic cylinder 18 extends, it causes the lower ends of the first rod 12 and the second rod 13 to move closer together, thereby causing the first rod 12 and the second rod 13 to raise the tool tray 6 relative to the fence 7; conversely, when the second hydraulic cylinder 18 retracts, it causes the lower ends of the first rod 12 and the second rod 13 to move further apart, thereby causing the first rod 12 and the second rod 13 to lower the tool tray 6 relative to the fence 7.

[0019] In practical use, tools and materials for facility inspection and maintenance can be placed in tool tray 6; when workers climb to the top of carriage 1 and railing 7 rises, as... Figure 4 As shown, when the second hydraulic cylinder 18 extends, the tool tray 6 rises relative to the fence 7, thereby facilitating workers to take tools and materials from the tool tray 6 and further improving work efficiency.

[0020] The carriage 1 is welded with transversely extending support beams 20. Several support beams 20 are provided and support the inner side of the top wall of the carriage 1, thereby improving the load-bearing capacity of the top of the carriage 1.
