DETAILED DESCRIPTION

[0021] In order to more clearly and completely illustrate the technical scheme of the utility model, the utility model will be further described below in combination with the drawings.

[0022] EMBODIMENT

[0023] As Figures 1-4 shown, an embodiment of the utility model proposes a high-altitude operation platform vehicle convenient for subway tunnel construction, mainly comprising fixed frame 1, pedal plate 2, standing plate 3, moving wheel 16 and pedal platform plate 4 and the like components. Fixed frame 1 is used as the support structure of the whole platform vehicle, and pedal plate 2 is installed on it for construction personnel to stand. The upper side of fixed frame 1 is fixedly connected with standing plate 3, and pedal platform plate 4 is installed between the two standing plates 3 through sliding connection mode, so as to adapt to the construction demand of different heights. At the same time, the side of standing plate 3 is also provided with a protection structure, so as to improve the safety in the construction process.

[0024] Among them, the protection structure comprises T-shaped sliding groove 7 opened on the surface of standing plate 3, T-shaped sliding rod 8 is slidingly connected in T-shaped sliding groove 7, and guardrail 9 is fixedly connected on T-shaped sliding rod 8. Construction personnel can adjust the position of guardrail 9 according to the need, so as to provide necessary protection. In addition, reset assembly is also connected between standing plate 3 and guardrail 9, which is used for automatically resetting after the movement of guardrail 9.

[0025] Further, in order to ensure that the stepping platform plate 4 stably slides between the standing plates 3 and does not slide excessively, the two opposite surfaces of the two standing plates 3 are transversely fixedly connected with U-shaped plates 5, and the stepping platform plate 4 can be slid into the U-shaped plates 5 to be fixed. At the same time, the opposite surfaces of the standing plates 3 are also fixedly connected with limiting blocks 6 to prevent the stepping platform plate 4 from moving excessively during the sliding process.

[0026] In order to limit the other end of the stepping platform plate 4, the ends of the two guardrails 9 are connected with limiting components. The limiting components include a connecting frame 10 fixedly connected to the end of the guardrail 9, and a limiting baffle 11 fixedly connected transversely in the connecting frame 10. When the stepping platform plate 4 is completely slid into the U-shaped plate 5, the other end of the stepping platform plate 4 abuts against the limiting baffle 11, thereby achieving limiting. Through the above limiting and connecting design, the sliding of the stepping platform plate 4 between the standing plates 3 is more stable and reliable, and the position can be adjusted as needed to adapt to the construction requirements of different heights. At the same time, the setting of the limiting component effectively prevents the excessive movement and accidental falling of the stepping platform plate 4, thereby improving the safety during the construction process.

[0027] Further, the reset assembly includes a strip-shaped groove 12 vertically formed in the surface of the standing plate 3, and a standing rod 13, a spring 14 and a sliding sleeve block 15 arranged in the strip-shaped groove 12. The standing rod 13 is fixedly connected between the two end walls of the strip-shaped groove 12 and serves as the support and guide of the spring 14 and the sliding sleeve block 15. The spring 14 is sleeved around the standing rod 13 and has two ends connected with the end wall of the strip-shaped groove 12 and the sliding sleeve block 15, respectively. The sliding sleeve block 15 is slidably connected in the strip-shaped groove 12 and has a surface fixedly connected with the guardrail 9.

[0028] When the guardrail 9 is moved, the sliding sleeve block 15 moves along with it and compresses the spring 14. When the external force disappears, the spring 14 releases the stored energy and pushes the sliding sleeve block 15 to reset, thereby driving the guardrail 9 back to the initial position. The design of the reset assembly enables the guardrail 9 to automatically reset to the initial position after being moved, without manual intervention, thereby improving the convenience and efficiency of the construction operation. At the same time, the buffering effect of the spring 14 also effectively protects the reset mechanism from damage caused by external impact, thereby prolonging the service life of the equipment.

[0029] Further, the limiting component mainly consists of the connecting frame 10 and the limiting baffle 11. The connecting frame 10 is fixedly connected to the end of the guardrail 9, and the limiting baffle 11 is fixedly connected transversely to the inner wall of the connecting frame 10. The limiting baffle 11 cooperates with the side edge of the stepping platform plate 4, and when the stepping platform plate 4 is completely slid into the U-shaped plate 5, the side edge of the stepping platform plate 4 abuts against the limiting baffle 11, thereby achieving limiting.

[0030] The limiting part is simple and effective in design, and can reliably limit the sliding range of the treading platform plate 4, preventing it from moving excessively or falling off accidentally. Meanwhile, the limiting baffle 11 is tightly matched with the side edge of the treading platform plate 4, improving the stability and safety during construction.

[0031] Further, the sliding sleeve block 15 is slidingly connected at the inner wall of the strip-shaped groove 12, and its surface is fixedly connected with the guardrail 9. This connection mode enables the sliding sleeve block 15 to move smoothly in the strip-shaped groove 12 and drive the guardrail 9 to move together. Meanwhile, the vertical solid rod 13 serves as a guide and support structure for the sliding sleeve block 15, ensuring its stability and accuracy during movement.

[0032] Further, the sliding sleeve block 15 is slidingly connected at the inner wall of the strip-shaped groove 12, and its surface is fixedly connected with the guardrail 9. This connection mode enables the sliding sleeve block 15 to move smoothly in the strip-shaped groove 12 and drive the guardrail 9 to move together. Meanwhile, the vertical solid rod 13 serves as a guide and support structure for the sliding sleeve block 15, ensuring its stability and accuracy during movement.

[0033] Further, the upper end of the spring 14 is fixedly connected to the lower end surface of the sliding sleeve block 15, and the lower end is fixedly connected to the end wall of the strip-shaped groove 12. When the guardrail 9 is moved, the sliding sleeve block 15 will move and compress the spring 14. The spring 14 will store energy when compressed and release energy to push the sliding sleeve block 15 back to its original position when the external force disappears.

[0034] Further, the upper end of the spring 14 is fixedly connected to the lower end surface of the sliding sleeve block 15, and the lower end is fixedly connected to the end wall of the strip-shaped groove 12. When the guardrail 9 is moved, the sliding sleeve block 15 will move and compress the spring 14. The spring 14 will store energy when compressed and release energy to push the sliding sleeve block 15 back to its original position when the external force disappears.
