Abstract
The utility model discloses a kind of automobile-used insulator crossarm, it comprises the insulator crossarm being connected with wire pillar; Insulator crossarm and the stressed joint of cross-arm bracket clamp; The lower end of cross-arm support is provided with the plug socket of band pin-and-hole; Plug socket overlaps corresponding grafting with the grafting at fixing plug top, and grafting is put and is provided with the pin-and-hole mutually corresponding with plug socket and is fixed by bearing pin; Fixing plug is provided with the bolt hole corresponding with arm installing hole, and its grafting is fixed by bolt.Because cross-arm support bottom is provided with the plug socket of band pin-and-hole, and plug socket overlaps mutual corresponding grafting with the grafting at fixing plug top, then is fixed by bearing pin, can ensure to be connected between cross-arm support with fixing plug fastening; In the fixing pluggable arm installing hole on insulation bucket arm dolly of plug, and its mutual grafting fixed by bolt, can ensure being fastenedly connected of fixing plug and the little workshop of insulation bucket arm, whole process one people can operate, and operating efficiency significantly improves.
Description
technical fieldthe utility model belongs to tools for live working technical field, be specifically related to a kind of can be arranged on aerial lift device with insulated arm be used for charged vertical rod, remove the automobile-used insulator crossarm of the work such as bar.
background technologyat present, the requirement of Guo Wang company to power supply reliability progressively improves, also more and more stricter to the service criterion requirements of client to power supply enterprise, and reduce user have a power failure area, reduce the most feasible modes such as customer outage hours and carry out live line working exactly; Live line working is that with high content of technology, a safe skill requires strictly, and the line maintenance method of remarkable in economical benefits, by the research of live line working Method and kit for and improvement, undoubtedly to raising live line working efficiency, expand charged job area, good effect can be played.Cross-arm is one of critical piece of overhead transmission line, insulator crossarm of the prior art needs unclamped by the insulator crossarm be replaced and be moved down into correct position before installing, then the installation of new insulator crossarm can be carried out, need during installation to be fixed by metal hinge, and installation process is complicated, need two people's cooperations to carry out, and needs the wire on original insulator crossarm upwards to turn to insulator crossarm after installation; Staff's multiple-contact live wire in operation process, the dangerous spot of existence is more, and labour intensity is large, is unfavorable for safety in production; Further, cross-arm fixes the effect as temporary support wire on online bar or other objects, and it is very inconvenient to use, and staff often can stand on aerial lift device with insulated arm and carry out operation, therefore needs a kind of Novel insulated crossarm that can be fixed on aerial lift device with insulated arm.
summary of the inventionthe purpose of this utility model solves prior art existence to need the inconvenience of many people coordinating operation, fixed form and ineffective technical problem, provides a kind of automobile-used insulator crossarm, overcome the deficiencies in the prior art.
To achieve these goals, a kind of automobile-used insulator crossarm of the utility model, it comprises insulator crossarm; Described insulator crossarm is connected with wire pillar; Described insulator crossarm and top are with the cross-arm bracket clamp stressed joint of snap ring; Its main points are plug sockets that the lower end of described cross-arm support is provided with band pin-and-hole; Described plug socket overlaps corresponding grafting with the grafting at fixing plug top, and grafting is put and is provided with the pin-and-hole mutually corresponding with plug socket and its grafting fixed by bearing pin; Described fixing plug is provided with the bolt hole mutually corresponding with the arm installing hole of insulation bucket arm dolly, and its grafting is fixed by bolt.
The utility model is rational in infrastructure, easy to use, because cross-arm support bottom is provided with the plug socket of band pin-and-hole, and plug socket overlaps mutual corresponding grafting with the grafting at fixing plug top, then be fixed by bearing pin, can ensure to be connected between cross-arm support with fixing plug fastening; In the fixing pluggable arm installing hole on insulation bucket arm dolly of plug, and its mutual grafting fixed by bolt, can ensure being fastenedly connected of fixing plug and the little workshop of insulation bucket arm, whole process one people can operate, and operating efficiency significantly improves.The utility model solves prior art existence and needs the inconvenience of many people coordinating operation, fixed form and ineffective technical problem.
accompanying drawing explanationaccompanying drawing is structural representation front view of the present utility model.
In figure 1, wire pillar 2, insulator crossarm 3, snap ring 4, plug socket 5, bearing pin 6, fixing plug 7, insulation bucket arm dolly 8, bolt 9, grafting cover 10, cross-arm support
embodimentwith reference to accompanying drawing, the utility model it comprise insulator crossarm 2; Described insulator crossarm 2 is connected with wire pillar 1; Described insulator crossarm 2 is in clamping connection with the cross-arm support 10 of top with snap ring 3; The lower end of described cross-arm support 10 is provided with the plug socket 4 of band pin-and-hole; Described plug socket 4 overlaps 9 corresponding grafting with the grafting at fixing plug 6 top, and grafting cover 9 is provided with the pin-and-hole mutually corresponding with plug socket 4 and its grafting is fixed by bearing pin 5; Described fixing plug 6 is provided with the bolt hole mutually corresponding with the arm installing hole of insulation bucket arm dolly 7, and its grafting is fixed by bolt 8.
The utility model reasonable in design, novelty, practical, use this automobile-used insulator crossarm, very convenient using aerial lift device with insulated arm charged vertical, when removing line bar, substantially reduce the activity duration, improve economic benefit.
