Abstract
The invention relates to an installation tool for a high-voltage switching device, in particular to an installation tool for a contact arm retainer ring of a handcart switch cabinet. The installation tool comprises a pair of parallel baseplate and top plate, wherein both sides of the baseplate and the top plate are connected with each other through a pair of guide posts; a pressure plate is arranged between the baseplate and the top plate; both sides of the pressure plate are matched with the pair of guide posts through a guide hole and can move up and down along the guide posts; a lower positioning concave cavity is formed on the baseplate; an upper positioning concave cavity opposite to the lower positioning concave cavity is formed below the pressure plate; the center of the upper positioning concave cavity is provided with a through hole for the upper end of an insertion rod of a plug-in contact to pass through; the top plate is matched and connected with a screw rod in a vertical direction through a screw hole; and the lower end of the screw rod is pressed against the pressure plate. The installation tool has the advantages of simple structure, easy manufacturing and capability of conveniently installing the plug-in contact on the end part of the contact arm of the handcart switch cabinet and improving installation efficiency.
Description
Technical field
The present invention relates to the erecting tools of high voltage switchgear, specifically is a kind of installation tool for contact arm retainer ring of handcart switch cabinet.
Background technology
In the handcart switch cabinet, conduct electricity by the straight line inserting mode between the stationary contact arm in acting arm on the handcart and the cabinet and be connected, therefore the contact of plug-in type will be installed at the contact arm front end, common plug-in type contact generally includes the contact of paired setting and is pressed in the stage clip in the contact outside, contact, stage clip and in the contact arm end between the contact by cross-under on the cross-under bar, the end of cross-under bar is installed back-up ring and is carried out spacing to the stage clip of inboard.In this structure, because the stage clip of plug-in type contact has certain precompression after installation, need first compression press spring when therefore installing, the annular groove that makes the cross-under boom end be used for installing back-up ring exposes, and back-up ring could be snapped in annular groove then, finishes the installation of back-up ring.Because stage clip has bigger spring force, compression press spring was very difficult when the assembler installed back-up ring, and specific purpose tool carries out auxiliary operation to the installation of back-up ring and still do not have preferably at present, thereby made troubles for the installation of contact arm.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of can carry out auxiliary operation to plug-in type contact and being connected of contact arm end, and simple in structure, easy to operate installation tool for contact arm retainer ring of handcart switch cabinet.
Installation tool for contact arm retainer ring of handcart switch cabinet of the present invention includes the base plate and the top board of pair of parallel, the both sides of base plate and top board are connected by the guide pillar of pair of parallel, be provided with a pressing plate between base plate and the top board, the pressing plate both sides cooperate with a pair of guide pillar by pilot hole and can move along guide pillar is upper and lower; Be provided with down the location cavity above the base plate, the cross-under boom end of plug-in type contact contact below and stage clip end all can be placed in down in the cavity of location; Be provided with below the pressing plate and down the location cavity relative go up the location cavity, the stage clip end of plug-in type contact contact top can be placed in the cavity of location, on locate the cavity center and have the through hole that passes on can cross-under bar for the plug-in type contact; Described top board is connected by the screw rod of a screwed hole and a vertical direction, and the lower end of screw rod withstands on the pressing plate.
The present invention is simple in structure, be easy to make, it easily the plug-in type contact of rival car formula switch cubicle contact arm end install, improved installation effectiveness.
