Description

Technical Field

[0001] The present application relates to the technical field of equipment lighting, and in particular to a laneway lamp lifting device. Background Art

[0002] At present, in the field of coal mine equipment lighting, the height setting of tunnel lights has become a major factor affecting production work. For a long time, underground coal mines have adopted the installation of a tunnel light at intervals of 5-15 meters to meet the lighting needs for underground tunnel lighting, so as to improve the safety of operations. With the upgrading of coal mine equipment, the design sections of various tunnels are constantly increasing, and the height is between 3.5-5m. Most tunnels have a certain angle. Generally, telescopic ladders are used to climb up to inspect or replace tunnel lights. In this way, there is a great risk of falling for personnel who inspect tunnel lights, which brings great pressure to mine safety production. In addition, since the location of the tunnel lights is usually high, it is difficult to adjust the height of the tunnel lights. The existing technology often fixes the tunnel lights at a certain height according to the lighting intensity required for the current work and the on-site conditions, but this method has limitations. When different work is performed at this position, the required lighting height may change. At the same time, due to the progress of lighting work, the current tunnel lights have aging problems. The lighting intensity will be weakened. At this time, the height of the tunnel lights needs to be adjusted. The fixed installation method is difficult to meet such conditions, affecting the normal operation of production work. Utility Model Content

[0044] In an optional embodiment of the present application, the first lifting rope 21 is an electric wire, and the first end of the first lifting rope 21 is installed on the top plate 11. The second end of the first lifting rope 21 passes through the first pulley 221 and the second pulley 222 and is connected to the lamp 30, thereby driving the lamp 30 to rise and fall while providing power to the lamp 30.

[0045] A sliding track is provided on the top plate 11 , and the first pulley 221 and the second pulley 222 are both connected with sliding members, so that the first pulley 221 and the second pulley 222 slide along the sliding track through the sliding members.

[0046] like Figure 5 As shown, the driving part includes a screw 31 and a driving member 32 for driving the screw 31 to rotate forward or reversely; the first pulley 221 and the second pulley 222 are both drivingly connected to the screw 31 to perform linear motion of sliding toward or away from each other through the rotation of the screw 31.

[0047] In an optional embodiment of the present application, the screw 31 is a screw with reverse threads at both ends. The first pulley 221 and the second pulley 222 are respectively located at the two opposite ends of the screw 31, and slide along the length direction of the screw 31 through the threads that cooperate with the screw 31.

During the lifting process, the operator can operate the driving member 32 to drive the lead screw 31 to rotate forward, thereby driving the first pulley 221 and the second pulley 222 to slide toward each other to lower the lamp 30, and the operator can operate the driving member 32 to drive the lead screw 31 to rotate reversely, thereby driving the first pulley 221 and the second pulley 222 to slide away from each other to raise the lamp 30.

The top plate 11 is installed on the top of the tunnel, and the first pulley 221 and the second pulley 222 make linear motions of sliding toward or away from each other on the top plate 11 through the lead screw 31. The operator operates the driving member 32 to drive the lead screw 31 to rotate forward or reverse to drive the first pulley 221 and the second pulley 222 to slide toward or away from each other, so that the first lifting rope 21 drives the lamp 30 to be lifted and lowered.
