Description

A mobile generating set with a liftable lighting tower

technical field

The invention relates to the field of generator sets, in particular to a mobile generator set with a liftable lighting tower.

Background technique

When working in emergency, disaster relief, construction and other occasions at night, large-area, high-brightness temporary light source equipment is required to provide lighting. At present, the commonly used solution is to temporarily set up lighthouses and install lamps, but this method not only takes a long time to build, but also has poor adaptability to the site. If there is no power supply near the site, cables need to be pulled over long distances, and it is difficult to adjust the lighting height and angle.

In the prior art, it is usually necessary to use a pneumatic pump or other starting devices to make the light pole flat and upright, which increases the manufacturing and purchase costs; and the lighting equipment can only provide lighting at one angle and direction, and if the lighting angle needs to be adjusted, the trailer needs to be moved The location and adjustment of the lighting angle are complex.

In the traditional generator set, the muffler is arranged inside the generator set cover, which leads to heat accumulation in the generator set cover and poor heat dissipation effect, resulting in excessively high temperature inside the generator set cover, which reduces the reliability and stability of the generator set operation.

Contents of the invention

The lighting tower structure includes a light pole front support, a retractable light pole, a light pole retractable winch, and a light pole vertical winch; the light pole front support is located outside the generator set box cover, and the bottom of the light pole front support connected to the chassis.

The light pole retractable winch is connected with the retractable light pole, and the light pole retractable winch rotates to make the retractable light pole shrink or extend along the length direction of the light pole so that the retractable light pole stretches.

The retractable light pole is sleeved in the outer sleeve of the light pole, and the outer sleeve of the light pole rotates around the front support of the light pole.

Lighting fixtures are arranged on the top of the retractable light pole.

The lamp pole upright winch is arranged on the front part of the chassis, and the lamp pole upside down winch rotates to make the outer sleeve of the lamp pole rotate around the front support of the lamp pole to realize the vertical state and power generation of the retractable lamp pole and the generator box cover. Switches the state where the case covers are parallel.

It can be seen from the above technical solutions that the retractable light pole of the present invention realizes the expansion and contraction of the retractable light pole by operating the light pole shrinkage winch, which has a simple structure, low cost, easy operation and strong reliability; The vertical state and parallel state of the pole and the generator box cover are switched, and the locking pin is used to realize the relative static of the light pole outer sleeve and the light pole front support, so that the upright of the retractable light pole is more reliable; the lower part of the retractable light pole A ring structure with holes is fixedly connected, and the ring structure is located at the position where the retractable light pole and the outer sleeve of the light pole are connected. A spring pin is connected to the outer sleeve of the light pole, and the spring pin and the ring structure The holes set on the top match, so that the retractable light pole and the outer sleeve of the light pole can do relative rotational movement. When the lighting angle is adjusted to a suitable position, the spring pin matches the hole set on the ring structure, so that the retractable The light pole and the outer casing of the light pole stop moving, and the angle of the lighting can be adjusted conveniently by adopting this structure.
