Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel lighting lamp bracket. Background Art

[0002] Tunnel construction refers to the process of excavating tunnels and laying various equipment and facilities during the excavation process. During the tunnel construction process, because the light inside is dim, it is necessary to use lighting to facilitate construction.

[0003] When pushing the lighting lamp in the tunnel construction section, if the lighting lamp is extended to the top of the tunnel through a telescopic rod for construction lighting, because the lighting lamp is at a high place, its center of gravity will shift to the side where the lamp is set. And because of the potholes on the road surface in the construction section, when the lighting lamp is pushed to illuminate the top of the tunnel, the shaking caused by the potholes in the road surface during movement will cause the lighting lamp extended to the top to tilt toward the place where the center of gravity is offset, making the lighting lamp easy to topple over, resulting in difficulty in stable support when pushed. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a tunnel lighting lamp bracket to solve the problem that when the lighting lamp is pushed to illuminate the top of the tunnel, the shaking during movement caused by potholes in the road surface will cause the lighting lamp extended to the top to tilt toward the center of gravity offset, making the lighting lamp easy to tip over, resulting in poor stable support when pushed. When the bracket top plate is driven to contact the tunnel top, the anti-skid pad first contacts the tunnel top wall, and then when the bracket top plate continues to be moved, the anti-skid pad is deformed and compressed into the top plate groove, thereby improving the stability of the bracket top plate when contacting the tunnel top wall through the anti-skid pad, and at the same time, the height of the lighting lamp can be adjusted by adjusting the height of the bracket top plate.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a tunnel lighting lamp bracket, comprising a frame assembly, an installation assembly, and a bracket assembly, the frame assembly comprising a bracket column, a supporting arm, and a positioning side plate, the inner side of the bracket column is provided with a side slot, the inner wall of the side slot is provided with a column through hole, the inner side of the supporting arm is provided with a supporting arm slot, the inner side of the positioning side plate is provided with a side plate slot, one end of the supporting arm is connected with a supporting arm block, the installation assembly comprises a mounting back plate and a lighting lamp, one end of the mounting back plate is connected with a connecting plate, the bracket assembly comprises a bracket top plate and a bracket bottom plate, a limiting screw is provided at the lower end of the bracket top plate, a fixing nut is provided at the outer ring of the limiting screw, a connecting riser is provided at the top of the bracket bottom plate, a connecting riser is provided at the outer ring of the connecting riser, and a connecting sleeve is provided at the inner ring of the connecting sleeve.

When the position of the support top plate is adjusted, the fixing nuts arranged at the upper and lower ends of the limit screw with the support bottom plate as the symmetrical point are first rotated and loosened in turn. At this time, the fixing nuts are released from contact with the support bottom plate, and then the position of the support top plate is adjusted.
