Technical Field
[0001] The utility model relates to the technical field of lighting devices, in particular to a lighting device used for rail vehicle maintenance. Background Art
[0002] In order to improve the safety of rail transportation, rail vehicles need to be regularly inspected and maintained. When inspecting the bottom of rail vehicles, lighting devices are needed to provide supplementary light. Traditional lighting devices need to be carried by workers themselves, which is cumbersome to operate and not easy to adjust.
[0003] Publication No. CN215722722U discloses a searchlight lighting device for rail vehicle maintenance, comprising a disc box and a protective shell, wherein the outer edge of the disc box is provided with a protective shell, and the protective shell is rotatably connected to the disc box, the edge of the disc box is evenly provided with lamp slots, and an irradiation lamp is elastically rotatably installed inside the lamp slot by a torsion spring, a main control circuit board is installed inside the disc box, and the main control circuit board is electrically connected to the irradiation lamp, an adjustment mechanism for adjusting the angle of the irradiation lamp is installed inside the disc box, and a broken slot is provided on the surface of the protective shell at a position corresponding to the lamp slot. The device is a disc-shaped structure as a whole, which saves more space and is more convenient to use. By evenly distributing the irradiation lamps and adjusting the angle thereof in conjunction with the adjustment mechanism, the irradiation range can be adjusted to meet the user's needs for maintenance lighting at different positions, and the operation is relatively convenient. In addition, the device adopts a protective shell for outsourcing protection and has a long service life. However, the following problems still exist in the actual use of this patent:
[0004] In order to save space, the above-mentioned device has a disc-shaped structure as a whole. However, since the area of the bottom of the carriage is usually large, installing only a single independent fixed light source can easily create shadow blind spots far away from this light source, which in turn makes it impossible for staff to directly observe the situation of the vehicle body. If multiple light sources are installed at the bottom of each carriage, the lighting cost will increase.
[0005] A lighting device for rail vehicle maintenance is proposed to solve the above-mentioned problems. Utility Model Content
[0006] The purpose of the present utility model is to provide a lighting device for rail vehicle maintenance, so as to solve the problem that the above-mentioned device proposed in the above-mentioned background technology has a disc-shaped structure as a whole in order to save space. However, since the area of the bottom of the car is usually large, only a single independent fixed light source is installed, which easily produces shadow blind spots far away from the light source, thereby making it impossible for staff to directly observe the car body. If multiple light sources are installed at the bottom of each car, it will cause the problem of increased equipment lighting costs.
[0007] To achieve the above-mentioned object, the present utility model provides the following technical solution: a lighting device for rail vehicle maintenance, comprising a mobile assembly mounted on the bottom surface of the vehicle;
[0008] The movable assembly includes a threaded sleeve slidably mounted on the bottom surface of the carriage, an illuminating assembly is provided at the bottom of the threaded sleeve, and the illuminating assembly includes a lamp holder, a lamp tube is fixedly mounted on the bottom of the lamp holder, a battery compartment is fixedly mounted on one side of the top surface of the lamp holder, a T-shaped bar is fixedly connected to the other side of the top surface of the lamp holder, a suspension shell is fixedly connected to the bottom surface of the threaded sleeve, a baffle is fixedly connected to the middle of the top surface of the lamp holder, a connecting column is plugged into the side of the baffle, and the connecting column passes through one side of the suspension shell and is fixedly connected to a ball;

[0017] 1. By inserting the T-shaped bar into the stepped groove, as the lamp holder is pushed, the T-shaped bar slides in the stepped groove. When the suspension shell moves to the end of the T-shaped bar, the connecting column is inserted into the suspension shell, and the ball squeezes the movable plate to move. At this time, the movable plate squeezes the roller to rotate the bending rod, thereby causing the splint to clamp the connecting column.

It only needs to be temporarily installed during inspection, saving equipment costs. It can also be left unremoved at other times. It only needs to light up the lamp tube when inspecting the bottom of the car, making this device more convenient to use. Moreover, the lamp tube can be quickly disassembled and maintained at this time. Moreover, the length of the lamp tube is larger than that of an independent bulb, and the movement of the lamp tube can effectively illuminate the inspection area of the bottom of the car, reducing the existence of blind spots in lighting.
