Embodiment Construction

[0014] In order to better understand the technical solution of the present invention, the following will be described in detail through specific examples:

[0015] see figure 1 , an array bolt hoisting chassis of the present invention, comprising a chassis base.

[0016] The chassis base is a rectangular frame structure, which is divided into front bearing side, rear bearing side and two sides. The top plate 2, the bearing top plate 1 and the side top plate 2 are supported on the bottom plate through the support plate 3, the height of the bearing top plate 1 is higher than that of the side top plate 2, and the contact parts of the two are tailor-welded. The inner side of the bearing top plate 1 is provided with triangular support ribs 4 for supporting the bearing top plate 1 on the bottom plate. The bearing top plate 1 is provided with a support platform knot 11 bent toward the side top plate, and the support platform 11 is supported on the side top plate 2 through the suppo...

Abstract

The invention discloses an array bolt hoisting underframe. An underframe base is of a rectangular frame structure, wherein a bearing top plate and a side top plate are supported on the underframe through supporting plates, and the bearing top plate is higher than the side top plate; hook-shaped connecting plates are arranged at the two ends of the bearing top plate correspondingly and fixedly connected with the bearing top plate through array bolts, and a hoisting tool is welded to each hook-shaped connecting plate; and bearing supporting tables are arranged at the two ends of the side top plate correspondingly, and the bearing supporting tables are higher than the bearing top plate. The array bolt hoisting underframe is high in mechanical structural strength, a motor is supported stably,overall hoisting operation of the motor can be achieved, and the array bolt hoisting underframe is suitable for narrow operation space where the motor is difficult to disassemble and assemble.

Description

technical field [0001] The invention relates to an array bolt hoisting chassis used in the field of electrical engineering. Background technique [0002] Conventional large-scale seated bearing motors cannot be hoisted directly due to their large overall weight. The bottom frame is prone to plastic deformation, resulting in the deviation of the gap between the stator and the rotor, and affecting the performance of the motor. Therefore, after the motor is debugged, it needs to be disassembled and packed separately. It is assembled after being transported to the site, which consumes a lot of manpower and material costs. In addition, in some application scenarios, such as marine motor application scenarios, due to limited installation and construction conditions, it is usually not possible to perform separate disassembly and assembly operations, and the entire motor including the chassis needs to be hoisted in for installation. In case of special working conditions such as t...
