Liftable self-propelled type steering travelling box type device

Abstract

The invention discloses a liftable self-propelled type steering travelling box type device. The liftable self-propelled type steering travelling box type device comprises a travelling mechanism, a perpendicular lifting mechanism and a box body, wherein the travelling mechanism comprises a beam; one end of the beam is fixedly connected with a rear travelling bridge; the other end of the beam is hinged with two steering oil cylinders, and is rotatably connected with a front travelling bridge; the two ends of the rear travelling bridge are equipped with travelling wheels; the two ends of the front travelling bridge are equipped with caterpillar band travelling devices; mounting bases are arranged on the caterpillar band travelling devices; extending-out ends of the two steering oil cylindersare hinged with the two mounting bases separately; the beam is connected to the box body through the perpendicular lifting mechanism; a battery pack, a controller and a hydraulic power station are arranged in the box body; and drive motors for providing power to the caterpillar band travelling devices are arranged in the caterpillar band travelling devices. Needed special equipment can be modifiedby mounting a distribution network inside the box body according to the needs, so that automatic get-on and get-off of a transportation vehicle is realized, and the problems of transferring the box body, traveling turning and water accumulating after a rainstorm under a narrow road condition are solved.

Description

technical field [0001] The invention relates to the application field of special box-type equipment for non-road walking, in particular to a liftable self-propelled steering and walking box-type device. Background technique [0002] At present, with the continuous deepening of the transformation of my country's urban distribution network and people's higher and higher requirements for power supply reliability, more and more special equipment for bypass is used in the transformation of distribution network, so as to realize the process of distribution network transformation. In case of power failure, the prerequisite for the normal use of bypass special equipment is to be close to the work site to reduce the auxiliary work time. [0003] In order to make bypass special equipment closer to the work site, the power system requires smaller and smaller dimensions of these bypass special equipment to achieve the purpose of crossing streets and alleys to reach the work site.

Problems solved by technology

[0003] In order to make bypass special equipment closer to the work site, the power system requires smaller and smaller dimensions of these bypass special equipment to achieve the purpose of crossing streets and alleys to reach the work site. At present, the power system generally uses mobile boxes to convert cars , mobile ring network cabinet vehicles and other special vehicles modified with second-class chassis to bypass distribution network operation equipment to solve the power outage problem caused by distribution network transformation. Special vehicles modified with second-class chassis are limited by the size of the car chassis. When passing through urban areas or residential areas, it is either impossible to pass due to the influence of external dimensions, or affects the passing space around it, which is likely to cause complaints and complaints

[0004] At present, in order to meet the needs of distribution network transformation in a small space, the power system generally chooses modular box-type equipment, transports it to the site by a flatbed truck, and transfers it to the work site by a forklift or crane. The equipment occupies a small space, but the disadvantage is that the operation mode of transportation by flatbed truck, forklift or crane transfer takes up more resources. For the interior of the residential area, it cannot be operated because there is no operating space for transfer vehicles. At the same time, these equipment are stored on site. Once In the event of heavy rain and water, water ingress will cause short circuit of the equipment, resulting in a wider power outage, and there are hidden dangers; another way is to choose trailer-type equipment, and pull the trailer-type equipment to the job site by towing the vehicle. The advantage lies in the trailer The size of the trailer-type equipment is small, and it can also be moved by manpower in a small area, and it occupies a small space. However, for the trailer-type equipment, although it generally does not need to be loaded and unloaded, it cannot be realized by a tractor for small radius turns; Towing requires the trailer-type special equipment to have a license plate, and there are many unsafe factors in the process of towing

[0005] Therefore, no matter whether modular equipment or trailer-type equipment is used, it is to solve the problem of small storage space on the job site, and cannot solve the problem of these devices passing to the job site under the narrow road space. The technical difficulties in solving such problems lie in: 1) special-purpose The problem of self-propelled and steering of equipment; 2) The problem of autonomous loading and unloading of special equipment to reach the site; 3) The problem of how to prevent rain and water when the equipment is stored on site for a long time
