Problems solved by technology

[0003] When installing the mine flameproof transformer in the mine, keep a distance from the ground. During installation, the user needs to lift the flameproof transformer, and install and fix it through the bolts through the support frame and the external frame. However, due to the large size of the flameproof transformer , requires the cooperation of multiple people to install, which is relatively time-consuming, labor-intensive, and reduces work efficiency

Embodiment 1

[0027] Such as Figure 1-3 As shown, a mine explosion-proof transformer includes a transformer main body 5, a hook 1 is fixed in the middle of the upper end of the transformer main body 5, the left and right sides of the hook 1 are located at the upper end of the transformer main body 5 and a connection port 2 is fixed, and the right end of the transformer main body 5 is fixed There is a support frame 3, and the lower end of the transformer main body 5 is inlaid with an auxiliary support device 4. The auxiliary support device 4 includes an adjustment bolt 41, a disc seat 42, a support mechanism 43 and a card slot 44, and the middle part of the upper end of the disc seat 42 is provided with a card slot 44. Adjusting bolts 41 are spirally connected to the front and rear ends of the disc seat 42, and the lower end of the disc seat 42 is evenly connected to a support mechanism 43. The support mechanism 43 includes a cover plate 431, a fixing bolt 432 and a telescopic plate 433, and...

Embodiment 2

[0030] Such as Figure 4 As shown, a mine flameproof transformer, the auxiliary support device 4 includes a fixed rotating shaft 45, an inlay groove 46 and a limit mechanism 47, the bottom surface of the disc seat 42 is evenly provided with an inlay groove 46, and the left and right ends of the inlay groove 46 The upper side is fixed with a fixed rotating shaft 45 , and the lower end of the inlay groove 46 is positioned at the bottom middle of the disc seat 42 to fix a limit mechanism 47 .

[0031] In specific implementation, the supporting mechanism 43 is connected to the position of the inlay groove 46 through the fixed rotating shaft 45, so that the supporting mechanism 43 can be rotated through the fixed rotating shaft 45 when not in use, folded and placed in the inlaid groove 46, and limited by the limit mechanism 47. position, reduce the occupied space of the auxiliary support device 4, and facilitate placement and storage. During use, the support mechanism 43 rotates th...

Embodiment 3

[0033] Such as Figure 5 As shown, a mining explosion-proof transformer, the limit mechanism 47 includes a limit slide plate 471, a chute 472, an installation box 473, a spring 474 and a pull block 475, and the outer end of the installation box 473 is evenly connected to the limit slide plate 471, The surface of the installation box 473 is uniformly provided with a slide groove 472 , the middle part of the slide groove 472 is inlaid with a pull block 475 , and the lower end of the pull block 475 is located on the upper side of the installation box 473 and is connected with a spring 474 inside.

Abstract

The invention provides a mining explosion-proof transformer, which relates to the field of transformers and comprises a transformer main body. An auxiliary support device is embedded at the lower endof the transformer main body. A user places the transformer main body laterally, embeds the disc seat at the lower end of the transformer main body through the clamping groove, rotates through two adjusting bolts to be in contact with the transformer main body in the clamping groove, fixes the disc seat on the transformer main body, adjusts and stretches out the disc seat through the three supporting mechanisms according to the mounting height, and pulls the telescopic plate out of the sleeve plate; a telescopic plate in the sleeve plate abuts against and is fixed through rotation of the fixing bolts, the other two similar operations are conducted, the transformer body plate body is supported in a triangular shape through the three supporting mechanisms, a user does not need to carry and support the transformer manually, and the user can conveniently and fixedly install the supporting frame and a fixing frame in a mine channel through bolts. Time and labor are relatively saved, manpower is saved, installation efficiency is improved, and the auxiliary supporting device can be taken down and repeatedly used after being installed.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a mine flameproof transformer. Background technique [0002] Mining explosion-proof transformers are used in places with explosion hazards in mines. This kind of transformer is mostly made of dry type. The main structural feature is that all the joint surfaces of the box shell are made according to the flameproof requirements, and can withstand the internal pressure of 0.8 MPa. It includes: the main body of the mining transformer, the high voltage head of the high voltage side inlet terminal And the low-voltage head at the outlet of the low-voltage side. [0003] When installing the mine flameproof transformer in the mine, keep a distance from the ground. During installation, the user needs to lift the flameproof transformer, and install and fix it through the bolts through the support frame and the external frame. However, due to the large size of the flameproof transformer , requi...
