Auxiliary frame of special electric vehicle

Abstract

The invention discloses an auxiliary frame of a special electric vehicle. The auxiliary frame is arranged on a vehicle chassis and is used for bearing and installing a ring main unit. The auxiliary frame comprises front longitudinal beams, rear longitudinal beams, a front cross beam and a rear cross beam; the front cross beam is connected between the two front longitudinal beams to form a front structure of the auxiliary frame, the rear cross beam is connected between the two rear longitudinal beams to form a rear structure of the auxiliary frame, and the front structure and the rear structureare connected together to form an integral structure. The front structure is used for bearing and installing a ring main unit, and the rear structure is used for arranging power operation tools; thelength of the front crossbeam is greater than the width of the ring main unit, the length of the rear crossbeam is equal to the width of the chassis frame, and the length of the front cross beam is greater than the length of the rear cross beam. The height of the whole electric special vehicle formed by refitting the second-class chassis can be reduced, so that the height limiting requirements ofmost existing garages are met; meanwhile, the bearing capacity of the electric special vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of electric special vehicles, in particular to a subframe of electric special vehicles. Background technique [0002] As a special vehicle for emergency repair engineering, electric power vehicles are mainly used for power companies to respond in time and quickly repair power equipment when power failures occur or when power equipment is routinely replaced, so as to ensure less or no power outages, which requires Electric personnel and electric equipment can be quickly transported to the job site and put into operation. However, because the existing electric special vehicle needs to carry a large number of special equipment for electric work, some of which are large electric equipment, such as ring main unit, transformer, generator set, etc., this requires the chassis to have a large space and carrying capacity, so the existing Most of the special electric vehicles are converted into special electric vehicl...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: 1. Occupying the roads in the community, affecting the passage of pedestrians and vehicles; 2. Since some cables are connected to 10kV high-voltage lines, there are potential safety hazards, so a large number of safety protection measures and special personnel need to be set up on the job site to prevent pedestrians Danger due to proximity; 3. Cables need to be dragged into the basement power distribution room for a long distance, which is time-consuming, laborious and inefficient; 4. Some electrical operations are noisy, and the noise disturbs the residents because the vehicles are parked close to residential buildings
