Mobile lighting tower based on chain drive

Abstract

A mobile lighting tower based on chain drive comprises a mobile trailer and a guide wheel assembly, wherein a tow rod is arranged at the front end of the mobile trailer; the guide wheel assembly comprises a support, a lifting mechanism, a wheel shaft, wheels, a motor and a chain; the support comprises a base body and supporting arms connected with the base body; the lifting mechanism comprises a guide cylinder, a sliding rod, a lead screw and a rocker; the guide cylinder is fixed to the tow rod; the sliding rod is installed inside the guide cylinder and can slide along the inner wall of the guide cylinder; a screw hole is formed in one end of the sliding rod; the other end of the sliding rod is in rotary connection with the support; the guide cylinder is arranged at one end of the lead screw in a rotating and penetrating mode, the end, where the guide cylinder is arranged, of the lead screw and the screw hole are screwed together; the rocker and the other end of the lead screw are fixedly connected; the rocker drives the lead screw to rotate; the wheel shaft penetrates through the supporting arms in a rotary mode; the wheel shaft is fixedly sleeved with a first chain wheel; the wheels are fixedly arranged on the wheel shaft in a sleeved mode; a drive shaft of the motor is provided with a second chain wheel; the chain is arranged on the first chain wheel and the second chain wheel in a sleeved mode, so that the second chain wheel drives the first chain wheel to rotate through the chain. The mobile lighting tower not only can move at a long distance conveniently, but also can move at a short distance conveniently.

Description

[0001] 【Technical field】 [0002] The invention relates to a mobile lighting tower, in particular to a chain-driven mobile lighting tower. [0003] 【Background technique】 [0004] When working in field operations, night rescue and disaster relief, building construction, firefighting, news interviews and other places, high-brightness temporary light sources and temporary energy equipment are usually required. The traditional solution is to temporarily build lighthouses, install lamps, and then Local cables are installed to solve the electricity problem, and the height and lighting angle of temporary lighthouses cannot be adjusted, nor can they be moved quickly, which is time-consuming and laborious, and the solution cycle is long. Therefore, technicians have begun to develop mobile lighting towers, and the mobile lighting towers are towed by external power vehicles for long-distance movement. [0005] However, it is inconvenient to use an external power vehicle to tow the mobil...

Problems solved by technology

[0005] However, when moving short distances, it is inconvenient to use an external power vehicle to tow the mobile lighting tower. At this time, it is necessary to use manpower to push the mobile lighting tower. However, due to the heavy weight of the mobile lighting tower itself, it is time-consuming and laborious to push.
