Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing:

[0015] A cuboid support for epoxy cloth profiles, including four inner columns 1 of epoxy cloth profiles with rectangular cross sections, four outer columns 2 of epoxy cloth profiles with rectangular cross sections, and six epoxy cloth profiles with trapezoidal cross sections The beam 4 and the vertical beam 11 connected in the shape of a square are all provided with an inner post 1 of an epoxy cloth profile on the four corners of the cuboid support, and the long side of the cross section of the inner column 1 of the epoxy cloth profile is arranged along the front and rear horizontal directions. The entire support can well resist the vibration and impact of the front and rear directions, and avoid the front and rear impact on the insulating support on the car caused by the front and rear shaking of the underground mine car when it moves. Three dovetail-shaped slots 3 are arran...

Abstract

The invention discloses a cuboid support adopting epoxy cloth profiles, and solves the problem about multi-direction impact shock resistance of a support of a mining explosive-proof and intrinsically safe type chained static var generator in an underground explosive-proof box. The cuboid support is characterized in that an epoxy cloth profile inner column (1) is arranged on each of four corners of the cuboid support, three dovetail-shaped clamp slots (3) are formed in the outer side surface of each epoxy cloth profile inner column (1) at intervals, and epoxy cloth profile beams (4) with trapezoidal cross sections are clamped with the dovetail-shaped clamp slots (3); an epoxy cloth profile outer column (2) with a rectangular cross section is propped against the outer side surface of each epoxy cloth profile inner column (1), and a through connecting bolt (9) sequentially penetrates through the epoxy cloth profile inner column (1), the corresponding epoxy cloth profile beam (4) and the epoxy cloth profile outer column (2) to be connected with a through connecting bolt nut (10). According to the arrangement mode, the impact load in all directions can be borne, the structure is compact, and the limitation requirements of the explosive-proof box are met.

Description

technical field [0001] The invention relates to a rectangular parallelepiped-shaped bracket, in particular to a bracket for supporting and placing a power unit of a chain-type static var generator for mining flameproof and intrinsically safe. Background technique [0002] Mine explosion-proof and intrinsically safe chain-type static var generator is a power supply system used in coal mines, so that the non-function required by the underground load can be dynamically compensated on the spot, which can improve the power factor of the underground power grid and reduce the power of lines and transformers. Reduce loss, improve power supply efficiency, achieve energy saving and consumption reduction, improve power supply quality, and promote mine safety production. Its core component is a cascaded power unit. The power unit uses a 1700V IGBT inside. The IGBT of this voltage level is not insulated, and the power unit will be charged during operation. It is necessary to solve the pr...
