Description

Technical Field

[0001] This utility model relates to the field of bridge inspection devices, and in particular to a climbing device for a bridge inspection vehicle that facilitates entry into the compartment. Background Technology

[0002] Traditional bridge inspection vehicles lack dedicated climbing devices on their inspection platforms. When inspecting long-span, variable-section bridges, inspectors often need to enter the box girder compartment for inspection. In the past, they would carry a portable stool to assist in climbing or step on the steel crossbeams of the inspection platform to "laboriously" enter the compartment. Furthermore, all inspection equipment had to be passed hand-to-hand to be brought into the compartment smoothly, which was laborious, time-consuming, and unsafe. This process also placed certain demands on the agility and physical strength of the inspectors. Utility Model Content

[0003] The purpose of this utility model is to provide a climbing device for bridge inspection vehicles that facilitates entry into the inspection chamber. By setting up a pedestrian ladder inside the inspection platform, it is convenient for maintenance personnel to climb.

[0004] To solve the above technical problems, the following technical solution is adopted:

[0005] This utility model provides a climbing device for a bridge inspection vehicle to facilitate entry into the chamber, including a pedestrian ladder and a track installed inside the inspection platform. The track is installed on both sides of the inner bottom of the inspection platform, and the pedestrian ladder is installed on the track and moves on the track.

[0006] Optionally, the bottom of the pedestrian staircase is provided with pulleys that cooperate with the track.

[0007] Optionally, four pulleys are provided, with every two pulleys located on one side of the bottom of the pedestrian staircase.

[0008] Optionally, the pulley is provided with a pulley positioning hole, the track is provided with a track positioning hole, and the positioning device is installed on the pulley positioning hole and the track positioning hole to fix the position of the pedestrian staircase.

[0009] Optionally, the positioning device includes a pin, one end of which is provided with a protruding ring.

[0010] Optionally, a plurality of the pulley positioning holes are evenly and circumferentially arranged on the pulley, and a plurality of the track positioning holes are evenly and spaced apart on the track.

[0011] Optionally, the height of the pedestrian staircase is less than that of the side railing of the detection platform.

[0012] Optionally, a magnet is provided on the side of the pedestrian staircase without steps, and the magnet is used to attract the pedestrian staircase to one end face of the detection platform.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0014] 1. This utility model provides a climbing device installed on a bridge inspection vehicle, which is convenient to use. The pedestrian ladder moves on the track, and its position can be easily located. The pedestrian ladder can be moved directly below the entrance of the chamber, and the inspection personnel can enter the chamber through the ladder to carry out the inspection, which improves the safety of maintenance and is labor-saving and efficient.

[0015] 2. This utility model uses pins to pass through the track positioning holes on the track and the pulley positioning holes on the pulley in sequence to fix the walkway in one position for use, preventing it from moving when maintenance personnel climb it. A magnet is provided at one end of the walkway. When the walkway is not in use, it can be fixed to one end face inside the maintenance platform, ensuring the usable space inside the maintenance platform and preventing the walkway from moving and interfering with the work of the staff inside when the maintenance platform is driven.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1

[0025] like Figure 1 As shown, this embodiment provides a climbing device for a bridge inspection vehicle that facilitates entry into the chamber, including a pedestrian ladder 2 and a track 3 installed inside the inspection platform 1. The track 3 is installed on both sides of the bottom of the inspection platform 1, and the pedestrian ladder 2 is installed on the track 3. The pedestrian ladder 2 can move on the track 3, making it convenient to move the pedestrian ladder 2 to a designated location.

[0026] The climbing device provided in this embodiment is installed in the pedestrian ladder 2 inside the testing platform 1, which facilitates maintenance personnel to climb into the box chamber to work.

[0027] Example 2

[0028] This embodiment provides a climbing device for a bridge inspection vehicle that facilitates entry into the chamber, based on Embodiment 1. Four pulleys 4 are provided at the bottom of the pedestrian stairway 2. Every two pulleys 4 are located on one side of the bottom of the pedestrian stairway 2 and cooperate with the guide rail on one side of the inspection platform 1. The pedestrian stairway 2 can be moved conveniently and quickly by moving the pulleys 4 on the track 3.

[0029] like Figure 3As shown, the pulley 4 is provided with several pulley positioning holes 41, which are evenly spaced around the circumference. The track 3 is provided with several track positioning holes 31, which are evenly spaced on the track 3. When the pedestrian stairway 2 is moved to the designated position for use, the pin 5 is passed through the track positioning holes 31 and the pulley positioning holes 41 to position the pulley 4 on the track 3, so as to prevent the pedestrian stairway 2 from moving during use and ensure the safety of the pedestrian stairway 2.

[0030] like Figure 3 , Figure 4 As shown, a protruding ring 51 is provided at one end of the pin 5, and no protruding ring 51 is provided at the other end of the pin 5. The end of the pin 5 without the protruding ring 51 passes through the track positioning hole 31 and the pulley positioning hole 41. The protruding ring 51 is provided to prevent the pin 5 from sliding out of the positioning hole.

[0031] like Figure 2 As shown, a magnet 6 is installed on the end face of the pedestrian staircase 2 without steps. The magnet 6 is attached to the railing on the end face of the detection platform 1, thereby fixing the pedestrian staircase 2 in place. This prevents the pedestrian staircase 2 from moving arbitrarily when the detection platform 1 is driven, thus avoiding interference with the work of personnel inside.

[0032] The height of the pedestrian staircase 2 is less than the height of the side railing of the detection platform 1 to ensure personnel safety when climbing.

[0033] When in use, the staff enters the testing platform 1, and the testing platform 1 moves to the bottom of the chamber. The staff moves the pedestrian staircase 2 inside the testing platform 1 so that the pedestrian staircase 2 is directly below the entrance of the chamber. One end of the pin 5 is inserted into the corresponding pulley positioning hole 41 and track positioning hole 31 of the four pulleys 4 to fix the position of the pedestrian staircase 2. The staff enters the chamber to work through the pedestrian staircase 2.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
