Description
technical fieldthe utility model belongs to substation equipment maintenance and repair technical field, is specifically related to a kind ofly to complete the dismounting of handcart circuit breaker Mume flower contact, the specific purpose tool of installation fast in switch cubicle upkeep operation.
background technologyin prior art, when overhauling switch cubicle, needing to check whether handcart circuit breaker Mume flower contact exists oxidation, discharging and the vestige such as to burn, if oxidation serious, have and discharge or burn marks, need to change Mume flower contact.
At present, transformer station's 10kV/35kV power distribution equipment mainly adopts intermediate switchgear cabinet, due to the difference of material, manufacturing process, the quality of mid-set switch cubicle handcart circuit breaker Mume flower contact, and there is some difference with the insertion depth, contact area etc. of bus bar side fixed contact, along with running time is elongated, the phenomenons such as oxidation is serious, contact resistance increases and electric discharge is burnt can be produced, even proximity switch cabinet such as to burn at the accident, brings potential safety hazard to the operation of equipment.
Because contact is mainly stuck in the draw-in groove of handcart circuit breaker conducting rod by anchor ear spring by Mume flower contact, if there is no specific purpose tool, be not easy to dismounting, install, and misoperation can damage contact, therefore, can not fast, economy, high-qualityly complete maintenance task.
summary of the inventionthe purpose of this utility model solves prior art to there is the bothersome unhandy technical problem of handling, provides a kind of Mume flower contact fast assembling-disassembling specific purpose tool, overcome the deficiencies in the prior art.
To achieve these goals, a kind of Mume flower contact fast assembling-disassembling of the utility model specific purpose tool, it comprises handle; Its main points are that one end of described handle is flexibly connected with the side of disc base; The opposite side of described disc base is fixed with disk draw-in groove; Groove on described disk draw-in groove external diameter and the mutual clamping in rear end of some fingertips; Described fingertip distributes ringwise around disk draw-in groove; The outer of described fingertip rear end is arranged with the annular anchor ear be fixedly connected on disc base; The rear end of described fingertip is carried out spacing under the common clamping of annular anchor ear and disk draw-in groove; Described its inside of the fingertip distributed ringwise is a cone-shaped cavity, and the inside of cone-shaped cavity is provided with the cone-shaped end of corresponding frictional connection mutual to it; The rear portion of described cone-shaped end is fixedly connected with one end of pushing ram; The other end of described pushing ram is connected with advance seat with disc base through disk draw-in groove; Described advance seat is flexibly connected with handle respectively by movable rod.
In order to adjust the advance distance of pushing ram, described pushing ram and the mutual silk of advance seat connect fastening.
The interspersed place of described pushing ram and disk draw-in groove is provided with one end and is fixed on the back-moving spring that the disk draw-in groove other end is fixed on pushing ram.
Reset for the ease of fingertip, the external diameter of described fingertip front and back end is respectively equipped with anchor ear spring.
The front end of described annular anchor ear is provided with the limiting card mutually corresponding with the draw-in groove on fingertip external diameter.
Described handle is provided with insulation rubber sleeve.
The utility model is rational in infrastructure, easy to use, and because fingertip distributes ringwise around disk draw-in groove, and rear end is by the common clamping lower limit of annular anchor ear and disk draw-in groove; The cone-shaped cavity corresponding frictional connection mutual to cone-shaped end of fingertip inside, and one end of pushing ram is connected the active force of the other end by handle with cone-shaped end, therefore can promote cone-shaped end to move, thus promotion fingertip is that petal type extends out unlatching, each contact jack-up dismounting of Mume flower contact the most at last.The utility model solves prior art and there is the bothersome unhandy technical problem of handling.
accompanying drawing explanationfig. 1 is structural representation of the present utility model;
Fig. 2 is using state reference diagram of the present utility model.
In figure 1, anchor ear spring 2, fingertip 3, annular anchor ear 4, disk draw-in groove 5, back-moving spring 6, movable rod 7, insulation rubber sleeve 8, handle 9, pushing ram 10, advance seat 11, groove 12, disc base 13, limiting card 14, draw-in groove 15, cone-shaped end 16, Mume flower contact
embodimentwith reference to accompanying drawing, the utility model it comprise handle 8; One end of described handle 8 is flexibly connected with the side of disc base 12; The opposite side of described disc base 12 is fixed with disk draw-in groove 4; Groove 11 on described disk draw-in groove 4 external diameter and the mutual clamping in rear end of some fingertips 2; Described fingertip 2 distributes ringwise around disk draw-in groove 4; The outer of described fingertip 2 rear end is arranged with the annular anchor ear 3 be fixedly connected on disc base 12; The rear end of described fingertip 2 is carried out spacing under the common clamping of annular anchor ear 3 and disk draw-in groove 4; Described its inside of fingertip 2 distributed ringwise is a cone-shaped cavity, and the inside of cone-shaped cavity is provided with the cone-shaped end 15 of corresponding frictional connection mutual to it; The rear portion of described cone-shaped end 15 is fixedly connected with one end of pushing ram 9; The other end of described pushing ram 9 is connected with advance seat 10 with disc base 12 through disk draw-in groove 4; Described advance seat 10 is flexibly connected with handle 8 respectively by movable rod 6; Described pushing ram 9 and advance seat 10 mutually silk connect fastening; Described pushing ram 9 is provided with one end with the interspersed place of disk draw-in groove 4 and is fixed on the back-moving spring 5 that disk draw-in groove 4 other end is fixed on pushing ram 9; The external diameter of described fingertip 2 front and back end is respectively equipped with anchor ear spring 1; The front end of described annular anchor ear 3 is provided with the limiting card 13 mutually corresponding with the draw-in groove 14 on fingertip 2 external diameter; Described handle 8 is provided with insulation rubber sleeve 7.
Operation principle: fingertip distributes ringwise around disk draw-in groove, and the corresponding clamping of groove of rear end and disk draw-in groove external diameter, by spacing for the rear end of fingertip connection under the common clamping of annular anchor ear and disk draw-in groove, the anchor ear spring on the external diameter of fingertip front and back end gathers to allow fingertip regain; The tapered cavity in middle part of fingertip, be connected with pushing ram with the cone-shaped end of its frictional connection, the other end of pushing ram is flexibly connected with handle by advance seat and movable rod, when firmly hold with a firm grip handle time, pushing ram can move forward, thus promote cone-shaped end and move, and finally to contact fingertip be that petal type extends out unlatching, contacts Mume flower contact 16 and extend out and take out.
The rear end of fingertip is clamped in intermediate position by the annular anchor ear in the utility model and disk draw-in groove, places it and departs from; Limiting card can carry out spacing to the maximum opening angle of fingertip, and clamping corresponding to the draw-in groove on fingertip external diameter; Back-moving spring can carry out elastic reset to pushing ram; Advance seat and the mutual silk of pushing ram connect, and are convenient to the displacement adjusting pushing ram, thus the displacement of the adjustment cone-shaped end also final opening angle size controlling fingertip, easy to use.
