Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Such as Figure 1 to Figure 4 As shown, the CRH5A type EMU fifth-level repair electrical cabinet transportation device of the present invention is made of carbon steel as a whole, and the overall height is 300mm. The transportation device includes two longitudinal beams 1, two beams 2, six roller bars 3, four L-shaped support plates 4 and four universal wheels 5; two longitudinal beams 1 and two beams 2 are vertically welded in pairs A rectangular underframe, six grooves 1-1 are arranged at equal intervals on the inner sides of two longitudinal beams 1, and the two ends of the rotating shafts of the six roller bars 3 are correspondingly placed in twelve grooves 1-1. The beam 1 is connected by rolling; the four L-shaped support plates 4 are respectively located at the four corners of the rectangular underframe, and are correspondingly welded on the out...

Abstract

The invention discloses a transporting device for a CRH5A motor train unit fifth-level-overhaul electrical cabinet and belongs to the technical field of electrical cabinet transportation. The transporting device comprises two longitudinal beams, two cross beams, six rolling bars, four L-shaped supporting plates an four universal wheels. The two longitudinal beams and the two cross beams are perpendicularly welded in a pairwise manner to form a rectangular bottom frame. Six grooves are formed in the inner side of each of the two longitudinal beams at equal intervals. The two ends of rotating shafts of the six rolling bars are arranged in the twelve grooves correspondingly. The rolling bars are connected with the longitudinal beams in a rolling manner. The four L-shaped supporting plates are located at the four corners of the rectangular bottom frame correspondingly and are correspondingly welded to the outer sides of the two longitudinal beams. The four universal wheels are fixed to the lower surfaces of the four L-shaped supporting plates correspondingly. The upper surfaces of the six rolling bars and the upper surfaces of the four L-shaped supporting plates are located in the same horizontal plane and are higher than the upper surface of the rectangular bottom frame. By the adoption of the transporting device, the labor intensity of operators is lowered, the production efficiency is improved, and operation risks are avoided.

Description

technical field [0001] The invention belongs to the technical field of electrical cabinet transportation, and in particular relates to a transportation device for the electrical cabinet of the fifth-stage maintenance of a CRH5A type EMU. Background technique [0002] The electrical cabinet of CRH5A EMU needs to get off the vehicle for maintenance, and the electrical cabinet is relatively heavy. The heaviest QEL cabinet is 243 kg. At present, three operators use rollers to transport the electrical cabinet from the first end to the second end. The transportation distance is about 25m. During the transportation, the electrical cabinet has the risk of tipping over, causing personal injury to the operators. To sum up, the use of rollers to transport electrical cabinets is labor-intensive, with low production efficiency and operational risks. Contents of the invention [0003] In order to solve the technical problems of high labor intensity, low production efficiency and operat...
