[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Example: Figure 1 —— Fig. 9 A self-service installation ladder vehicle for overhead leaky cables of a high-speed railway bridge is shown, comprising:

[0033] Car body 1;

[0034] The second car body 2 is connected to the first car body 1 by bolts; a handrail 13 is connected between the first car body 1 and the second car body 2. Figure 1 As shown, a handrail 13 is provided between the vehicle body 1 and the vehicle body 2. When the vehicle body 1 and the vehicle body 2 need to be moved, the handrail 13 can be pushed to move the vehicle body 1 and the vehicle body 2 simultaneously on the cement board 23. In this embodiment, the cement board 23 refers to the guardrail of the bridge at the work site.

[0035] The working platform 3 is connected to the vehicle body 1 through a lifting assembly, and the height of the working platform 3 is adjusted by the lifting assembly. A guardrail 22 is detachably installed on the working platform 3. Figure 1 , Figure 2 As shown, in order to prevent the workers standing on the working platform 3 from falling from a height, a guardrail 22 is added above the working platform 3, which can provide a certain degree of protection for the workers. Similarly, the guardrail 22 is connected to the working platform 3 by bolts, and after use, the workers can choose to remove the guardrail 22 from the working platform 3.

[0036] A pedal 4 is fixedly mounted on the work platform 3, and one or more protrusions in the shape of a triangle, a sphere, a rectangle or a trapezoid are arranged on the pedal 4. Figure 3As shown, a pedal 4 can be set above the working platform 3, and protrusions of various shapes can be selectively set on the upper surface of the pedal 4, such as triangle, sphere, rectangle or trapezoid, as well as other irregular shapes such as hexagon known to those skilled in the art. The purpose of this is that when the staff stands on the pedal 4, the friction between the pedal 4 and the sole is increased by the set protrusions, thereby preventing the staff from slipping from the working platform 3 and playing a protective role.

[0037] At least four moving wheels 5, two of which are rotatably mounted on the vehicle body 1, and the remaining two moving wheels 5 are rotatably mounted on the vehicle body 2;

[0038] There are two stabilization components, and the two stabilization components can be detachably installed on vehicle body 1 and vehicle body 2 respectively.

[0039] like Figure 1 — Figure 3 As shown, when in use, the car body 1 and the car body 2 are connected together by bolts, and the moving wheels 5 on the car body 1 and the car body 2 fall on the cement board 23 respectively. The staff stands on the working platform 3 to install the leaky cable. The height of the working platform 3 can be adjusted by the lifting component, so that the leaky cable at different heights from the ground can be installed. In the process of installation, the car body 1 and the car body 2 can be pushed to move, so that the moving wheels 5 move on the cement board 23 to change the installation position. In addition, after use, the bolts on the car body 1 and the car body 2 can be removed, and the car body 1 and the car body 2 can be collected and transported respectively, reducing the transportation space. The function of the stabilization component is to reduce the shaking amplitude of the car body 1 and the car body 2 and the working platform 3 during the movement of the car body 1 and the car body 2, so as to prevent the staff standing on the working platform 3 from falling.

[0040] One end of two escalators 7 are rotatably mounted on the working platform 3, and the other end of the escalator 7 is slidably matched with the vehicle body 1.

[0041] like Figure 1 — Figure 3 As shown, when the staff needs to climb onto the working platform 3 to work, the staff first stands on the vehicle body 1, and then climbs onto the working platform 3 through the escalator 7.

[0042] The lifting assembly includes at least one lifting cylinder 6, which is fixedly installed on the vehicle body 1. The protruding end of the lifting cylinder 6 is fixedly connected to the working platform 3. The lifting cylinder 6 is used to control the distance of the working platform 3 relative to the vehicle body 1.

[0043] like Figure 1 — Figure 3As shown, when it is necessary to adjust the distance of the working platform 3 relative to the vehicle body 1 (i.e., the distance of the working platform 3 relative to the ground), the lifting cylinder 6 fixedly installed on the vehicle body 1 is started, so that the protruding end of the lifting cylinder 6 drives the working platform 3 to rise or fall, thereby completing the height adjustment of the working platform 3. In the process of rising and falling of the working platform 3, since the escalator 7 is rotatably installed on the working platform 3, the angle between the escalator 7 and the vehicle body 1 will change. On the one hand, the escalator 7 can always be made convenient for the staff to climb, and on the other hand, the escalator 7 is prevented from interfering with the rising and falling of the working platform 3.

[0044] The lifting assembly also includes two symmetrically arranged rotating rods 8, one end of which is rotatably mounted on the vehicle body 2, and the other end of which is slidably matched with one end of the rotating rod 11, and the other end of the rotating rod 11 is rotatably mounted on the vehicle body 1.

[0045] The first rotating rod 8 is provided with a positioning hole 9 , and the second rotating rod 11 is provided with a plurality of linearly arranged center holes 12 , and the positioning hole 9 is connected to the center hole 12 via a latch 10 .

[0046] like Figure 4 —— Figure 6 As shown, when adjusting the height of the working platform 3, that is, when the working platform 3 is raised or lowered, the rotating rod 2 11 connected to the working platform 3 will move with the working platform 3. Since the rotating rod 2 11 and the rotating rod 1 8 are in sliding cooperation, the rotating rod 1 8 will rotate on the vehicle body 2 2. Since the rotating rod 1 8 and the rotating rod 2 11 are in sliding cooperation, the rotating rod 1 8 and the rotating rod 2 11 will slide relative to each other during this process without causing interference. After the height adjustment of the working platform 3 is completed, the latch 10 is inserted into the positioning hole 9 and the center hole 12 to complete the locking of the rotating rod 1 8 and the rotating rod 2 11, thereby improving the stability of the working platform 3. A plurality of center holes 12 are provided on the rotating rod 2 11 to adapt to the positioning of the working platform 3 at different heights. In addition, the rotation connection between the rotating rod 1 8 and the vehicle body 2 2, and the connection between the rotating rod 2 11 and the vehicle body 1 1 can be set as a detachable structure, such as providing a rotating seat at the connection, and the rotating seat is connected to the vehicle body 1 or the vehicle body 2 2 by bolts, so that it is easy to disassemble and transport after use.

[0047] The stabilization component includes a rectangular plate 17, on which one end of a rocker arm 18 is rotatably mounted, and the other end of the rocker arm 18 is rotatably connected to an arc block 19, on which two symmetrically arranged counterweight blocks 20 are fixedly mounted, and an arc groove 21 is provided on the rectangular plate 17, which slides in cooperation with the arc block 19.

[0048] The stabilization component includes two symmetrically arranged connecting rods 14, one end of the connecting rod 14 is rotatably connected to the rectangular plate 17, and the other end of the connecting rod 14 is rotatably connected to the U-shaped block 15. The U-shaped block 15 is provided with a U-shaped groove 16, and the U-shaped groove 16 is provided with a plurality of rotatably mounted steel balls.

[0049] like Figure 1 , Figure 2 , Figure 4 ,like Figure 7 —— Fig. 9 As shown, when the positions of the car body 1 and the car body 2 are fixed, the state of the swing rod 18 is vertically downward. When the leakage cable installation at one place is completed, it is necessary to turn left (by Figure 2 When the vehicle body 1 and the vehicle body 2 are pushed to change their working positions, due to the existence of inertia, the person standing on the working platform 3 will tend to move to the right relative to the vehicle body 1 and the vehicle body 2 moving to the left. At this time, the vertical downward swing rod 18 will also swing to the right due to inertia, so that the end of the swing rod 18 connected to the arc block 19 will swing to the right, so that the counterweight block 20 on the arc block 19 will swing to the right along the arc groove 21 along with the arc block 19. In this way, the inertial force generated when the vehicle body 1 and the vehicle body 2 move suddenly can be offset by the swing rod 18 and the counterweight block 20, thereby reducing the shaking caused by the sudden movement of the vehicle body 1 and the vehicle body 2, thereby ensuring the personal safety of the staff standing on the working platform 3. In the actual working process, in order to avoid the staff from climbing up and down repeatedly, a staff member is often reserved on the ground during the working process to move the vehicle body 1 and the vehicle body 2. Therefore, it is necessary to solve the safety problem of the staff standing on the working platform 3 when the vehicle body 1 and the vehicle body 2 move.

[0050] The U-shaped groove 16 is just in close contact with the three adjacent surfaces of the cement board 23. In the process of pushing the vehicle body 1 and the vehicle body 2 to move, the U-shaped block 15 will move along the cement board 23, stabilizing the moving wheel 5, and the steel ball on the U-shaped groove 16 can reduce the friction force, making the movement of the vehicle body 1 and the vehicle body 2 more gentle. If the friction force is too large, the force used to drive the vehicle body 1 and the vehicle body 2 to move will inevitably increase. When the vehicle body 1 and the vehicle body 2 suddenly start to move, the risk of shaking of the staff standing on the working platform 3 will increase.

[0051] As an optional method, the rectangular plate 17 can be connected to the car body 1 and the car body 2 2 by means of bolts. After use, the bolts between the rectangular plate 17 and the car body 1 and the bolts between the rectangular plate 17 and the car body 2 2 can be removed and cut.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present invention as above, which are not provided in detail for the sake of simplicity. Although the present invention has been described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the above embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
