[0002] As an important part of modern transportation facilities, tunnels refer to three-dimensional passage buildings built through the interior of the stratum or underwater areas. Their main structure includes the load-bearing tunnel section and the tunnel portal structure that serves as a enclosure. During the construction period or maintenance power outage stage, due to the lack of natural light introduction, it is necessary to rely on artificial auxiliary lighting systems to maintain the construction environment. Although the mobile lighting brackets currently used in tunnel projects have basic advantages such as convenient operation and better economy, the limitations of their structural design lead to scattered light effects, which are not easy to move and adjust to a suitable height.

[0003] The existing announcement number CN220228948U discloses a mobile bracket device for tunnel construction lighting, which includes a device body and a mobile power supply; a first adjustment slot is symmetrically opened on the top wall of the device body, and a mobile power supply is fixedly arranged on the front side wall of the device body, and the mobile power supply is located between the first adjustment slots on the left and right sides; it also includes: a universal wheel, which is a plurality of universal wheels and is respectively fixedly arranged on the four corners of the bottom wall of the device body; an adjustment motor, which is a plurality of adjustment motors and is respectively fixedly arranged on the left and right side walls of the device body, and an adjustment shaft is fixedly arranged after the output end of the adjustment motor passes through the device body, and the inner end of the adjustment shaft is rotatably arranged in the inner side wall of the first adjustment slot, and the adjustment motor is electrically connected to the mobile power supply through a wire; an adjustment plate, which is a plurality of adjustment plates and is sleeved and fixed on the adjustment shaft; a mounting seat, which is a plurality of mounting seats and is fixedly arranged on the top wall of the adjustment plate; a lighting lamp, which is a plurality of lighting lamps and is fixedly arranged on the arc surface of the mounting seat at equal intervals, and the lighting lamp is electrically connected to the mobile power supply through a wire.

[0004] The prior art has the following technical defects:

[0005] The overall structure of the above technical solution is bulky. When the lighting lamp is lifted and rotated, its overall center moves upward, the overall stability is insufficient, and it is easy to topple over, thereby affecting the safety of workers on the construction site and affecting the construction progress. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a mobile bracket for tunnel construction lighting.

[0011] The X-shaped base is provided with a fixing pin, and the adjusting wheel seat is provided with a pin hole corresponding to the fixing pin, and the adjusting wheel seat can be quickly reset and fixed through the pin hole.

[0012] The angle adjustment component includes a rotating column and a rotating groove symmetrically arranged on the lighting lamp holder. The lighting board is provided with a rotating hole corresponding to the rotating column and a fixed column adapted to the rotating groove. An elastic limiting rod is provided in the rotating groove. The lighting board can rotate with the rotating column as the center. The fixed column on the lighting board slides in the rotating groove.

When the lighting lamp needs to be raised or lowered to a higher position, the position can be adjusted by adjusting the adjusting wheel seat at the bottom of the X-base, thereby increasing the stability of the X-shaped base and avoiding the risk of tipping over due to the increased center of gravity.
