Problems solved by technology

At present, since there is no special adjustment tool, it is very difficult for the operator to fine-tune the verticality and horizontal displacement after the installation unit lifts this type of power equipment into place. The common method is to use a wooden hammer or a crowbar to hit After adjustment, the installation accuracy after splicing often cannot meet the requirements, which increases the difficulty of the later work such as busbar lapping and switch knife debugging.

Embodiment Construction

[0011] see figure 1 . This device mainly includes a hydraulic mechanism composed of a main oil cylinder, an oil return cylinder and an oil storage cylinder arranged in the shape of an overall horizontal "one". The seal forms a solid axial unit whose cross-section forms a square. Among the inner cavities of the three, a piston is arranged in the inner cavity of the oil return cylinder, and its piston rod 11 is used as a work implement, and stretches out the end of the oil return cylinder forward. Considering the sealing problem, a connection seat is provided at the end of the oil return cylinder 9, and the sealing nut 10 is screwed on the connection seat, and the sealing surface of the outer wall of the piston rod 11 is prevented from leaking through the seal. The oil return cylinder inner cavity at the piston rear portion communicates with the oil storage cylinder 13 inner cavity through the oil passage on the main oil cylinder 7, and the on-off of the oil passage is control...

Abstract

The invention relates to a portable device assisting a switch cabinet to get in position. The device comprises a hydraulic mechanism consisting of a main oil cylinder, a return oil cylinder and an oil storage cylinder which are integrally arranged in a horizontal '-' shape; one end of a piston rod of a piston installed in the return oil cylinder extends out of the end part of the return oil cylinder, the main oil cylinder is provided with a manual power element; the tail part of the oil storage cylinder is provided with a joint which is connected with extension rods by bolts, the tail part ofthe extension rod is provided with a skid-proof seat; the piston rod is a hollow tube which is screwed with an adjusting screw rod through internal screw threads, extension rods are all hollow tubes and are connected into a whole by the bolts. The invention plays an assistant role for installing large electric devices, installation persons can very conveniently adjust the horizontal displacementsof the large electric devices, such as centrally-mounted switch cabinets, a protection screen and the like, thereby the installation quality of the electric device is ensured and potential safety hazards are eliminated.

Description

【Technical field】 [0001] The invention belongs to a device for assisting the installation of electric equipment, in particular to a portable device for assisting the positioning of a switch cabinet. 【Background technique】 [0002] Central switch cabinets, protective screens, etc. are large-scale electrical equipment, and the weight is mostly between 200 and 1000kg. At present, since there is no special adjustment tool, it is very difficult for the operator to fine-tune the verticality and horizontal displacement after the installation unit lifts this type of power equipment into place. The common method is to use a wooden hammer or a crowbar to hit After adjustment, the installation accuracy after splicing often cannot meet the requirements, which increases the difficulty of later work such as busbar lapping and switch knife debugging. 【Content of invention】 [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention aims to pr...
