Description

Technical Field

[0001] This utility model relates to a mobile lighting device for coal mining areas. Background Technology

[0002] During coal mining, temporary lighting needs to be added along the way as the tunneling progresses. After the mine shaft is reinforced with concrete in the later stages, permanent lighting will be installed.

[0003] In the existing technology, this temporary lighting uses emergency lights, which are supported by a pole at the bottom. The direction of the lighting is changed by adjusting the orientation of the emergency light.

[0004] However, during the mining process, the ground vibrates, making these conventional, fixed emergency lights very prone to falling over, which can damage the light source.

[0005] Therefore, we have designed a mobile lighting device specifically for use in coal mining areas that can be stably placed. Utility Model Content

[0031] See Figure 1 The illustrated mobile lighting device for coal mining areas includes a flashlight 1, a bracket 2, and a support rod 3. The bottom of the support rod 3 is supported on the ground, and the upper end of the bracket 2 is supported on the top surface of the mine tunnel. The flashlight 1 is mounted on the bracket 2.

[0032] In the above technical solution, the matching position of the support rod 3 and the bracket 2 can be adjusted to adapt to mine tunnels of different heights.

[0033] Flashlight 1 is a rechargeable flashlight that can provide illumination.

[0034] See Figure 2 As shown, a connecting sleeve 21 is welded to the top of the bracket 2, and an anchor rod 22 is rotatably installed through the connecting sleeve 21.

[0035] The anchor bolt 22 is conical, with its diameter gradually decreasing upwards, and acts on the top surface of the mine tunnel through the top of the anchor bolt 22.

[0036] In the above technical solution, the top of the mine tunnel is held in place by the anchor rod 22, and the bracket 2 can rotate along the positioning held in place by the anchor rod 22, thereby adjusting the direction of the flashlight 1.

[0037] See Figure 2 As shown, a first connecting sleeve 23 is welded to the inner top position of the bracket 2. A universal ball 27 is installed inside the first connecting sleeve 23. A fixing cap 24 is screwed into the bottom of the first connecting sleeve 23. A portion of the universal ball 24 extends to the outside of the fixing cap 24. The fixing cap 24 is screwed on and locked to the universal ball 27. A connecting rod 25 is machined at the position where the universal ball 27 is exposed outside the fixing cap 24. A plug sleeve 26 is provided at the end of the connecting rod 25. The flashlight 1 is inserted into the plug sleeve 26.

[0038] In the above technical solution, the orientation of the insert 26 can be adjusted by rotating the universal ball 27, so that the angle of the light direction of the flashlight 1 can be adjusted to meet the lighting needs during mining.

[0039] See Figure 3 As shown, a magnet 101 is glued and fixed to the end of the flashlight 1, and an iron plate that attracts the magnet 101 is provided inside the sleeve 26.

[0042] An adjustable sliding sleeve 32 is fitted on the support rod 3. A hand-tightening screw 33 is installed between the sliding sleeve 32 and the support rod 3. The upper end of the support rod 3 is inserted upward into the interior of the bracket 2 and fitted with a limit cap 34. A spring 35 is fitted on the support rod 3. The spring 35 acts between the bracket 2 and the sliding sleeve 32.

[0043] An operating handle 221 is provided on the outside of the bracket 2.

[0044] The operation method of the above technical solution is as follows:

[0045] First, adjust the position of the sliding sleeve 32 so that when the spring 35 is relaxed, the height of the bracket 2 and the support rod 3 combined is higher than the height of the mine shaft.

[0046] Then, at the location where lighting is needed, press down on bracket 2 to compress spring 35, keep bracket 2 upright, and then release bracket 2. At this time, spring 35 rebounds, so that the upper end of bracket 2 presses against the top of the mine tunnel, while the base plate 31 is supported on the ground, keeping the device firmly set up in the mine tunnel and providing stable lighting.
