Problems solved by technology

[0004] However, the safety protection performance of the existing maintenance platform is low, so that the maintenance personnel often lack certain safety protection measures when performing maintenance on the tunnel top wall, which causes the maintenance personnel to fall from the maintenance platform, causing serious damage to the life safety of the maintenance personnel. Threat, and because of the special environment in the subway tunnel, that is, the light is dark, it is difficult for maintenance personnel to check the surrounding environment during operation, and it is more likely to cause maintenance personnel to fall from the maintenance platform;
[0005] In view of the above, we provide a movable protective device for rail transit construction, which is used to solve the problem that the maintenance personnel who are in the high work are easy to fall when they are doing maintenance work on the tunnel roof

Embodiment 1

[0044] Embodiment 1, this embodiment provides a kind of protective device for mobile rail transit construction, refer to the attached figure 1 As shown, the track inspection car 1 is included and the inspection box 3 is vertically slidably installed on the track inspection car 1. figure 1 It is a schematic diagram of the track inspection vehicle 1 traveling in the tunnel 2, with figure 2 It is a schematic diagram when the track inspection car 1 is in the maintenance state (at this time, the inspection box 3 is in the raised state), the track inspection car 1 is equipped with a lifting mechanism and the inspection box 3 is lifted by the lifting mechanism, it is characterized in that, refer to the attached Figure 9 As shown, the inspection box 3 is divided into upper and lower two compartments through a partition 5, and the upper end surface of the partition 5 is connected with a vertically sliding bearing plate 6 installed in the inspection box 3 through a telescopic spring 4...

Embodiment 2

[0049] Embodiment 2, on the basis of embodiment 1, with reference to appended Figure 7 As shown, the bottom of the maintenance box 3 is horizontally spaced and fixedly equipped with a slide bar 15 and the track inspection car 1 is equipped with a slide tube 16 that is vertically slidingly matched with the slide bar 15 (the slide bar 15 and the slide tube 16 that cooperate with each other make the overhaul box 3 Move vertically under the action of the lifting mechanism to complete the lifting process of the inspection box 3), refer to the attached figure 2 As shown, a locking block 17 is laterally slid on the sliding tube 16 and a locking hole 18 matching the locking block 17 is provided on the sliding rod 15, and a locking spring 19 is connected between the locking block 17 and the sliding tube 16. A lifting plate 20 is vertically slidably installed in the expansion plate 14, and a lifting spring 21 is connected between the lifting plate 20 and the expansion plate 14. A pres...

Embodiment 3

[0051] Embodiment 3, on the basis of Embodiment 2, how the micro-control processor controls the withdrawal of the locking block 17 from the locking hole 18 that cooperates with it will be described in detail in this embodiment. 17 is connected with the locking spring 19 and one side is fixed with an iron piece and an electromagnet is fixed on the sliding cylinder 16 corresponding to the iron piece. The loop is controlled by a microcontroller processor;

[0052]When the protective device was in a normal state, that is, when the maintenance personnel did not fall, the voltage stabilized power circuit was in a disconnected state under the control of the microcontroller processor, that is, the locking block 17 was not attracted by the magnetic force from the electromagnet (the electromagnet No electricity and no electromagnetic force), when the inspection box 3 is not lifted by the lifting mechanism, the locking block 17 is in contact with the wall of the slide bar 15 that is vert...

Abstract

The invention relates to a movable protective device for construction of rail transit. The existing problem that maintenance personnel is prone to falling from a high place and the safety of the maintenance personnel cannot be guaranteed when the maintenance is carried out on the top wall of a subway tunnel is effectively solved. According to the technical solution, a bearing plate and arc-shapedhoardings are arranged so that when the maintenance personnel is falling from a maintenance box, a buffer plate is triggered to unfold and used for catching the maintenance personnel, and an expansionplate is further installed on the buffer plate. When the buffer plate is fully unfolded, the expansion plate slides out of the buffer plate, so that an area for accepting the maintenance personnel isfurther increased, and the risk of the maintenance personnel falling directly on the tunnel ground is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of protection devices, in particular to a protection device for movable rail transit construction. Background technique [0002] Rail transit, such as general railway, high-speed rail, light rail, subway, etc., they play an important role in the transportation field, and ensuring the normal operation of rail transit depends on the construction, maintenance and repair of rail transit-related facilities. The work involves personnel safety, especially the related work in the subway tunnel. The subway tunnel wall bears the weight of the soil layer above it, and its safety performance is directly related to the safe operation of the subway. Therefore, the subway tunnel wall It needs to be inspected and maintained on a regular basis to prevent the overall protection performance of the tunnel wall from being reduced due to cracks; [0003] When inspecting the area where the inner wall of the subway tunnel is below...
