Abstract
The utility model relates to a handcart propelling mechanism for handcart type high-tension switch cabinets, which is composed of a pair of connecting rods, a manual lever, a fulcrum shaft of which is arranged on a switch cabinet body and a guide bar of a handcart, wherein, the connecting rods are respectively hinged on the both sides of the handcart; the manual lever is divided into two parts from a fulcrum, and the two parts are a handle and a turn arm; the turn arm and the connecting rods are hinged with each other by a pin shaft; one end of the guide bar of the handcart is connected with the switch cabinet body, and the other end of the guide bar of the handcart is placed in a guide sleeve of the handcart. When the manual lever rotates around the fulcrum shaft of the manual lever, the handcart can be propelled or pulled out rapidly and smoothly by the connecting rods.
Description
The utility model belongs to mechanical translation mechanism, specifically a kind of handcart advancing mechanism of handcart type high-voltage switch cabinet.
The main electric component of handcart type high-voltage switch cabinet and movable contact are first-class to be installed on the handcart, so how to guarantee that switch cubicle be pulled out and be pushed to handcart can flexibility and reliability is one of important step of this type of switch cubicle operate as normal.At present, the propulsive mechanism of handcart switch cabinet mainly contains feed screw nut formula, Worm-gear type and the lever that lands.The fltting speed of feed screw nut formula and Worm-gear type is slow, and the operating time is long, and effort, and structure is complicated, and manufacturing cost is higher.Feed screw nut's formula also is prone to " getting stuck " phenomenon, and particularly its resistance obviously increases in the process of dynamic and static contact contact, easily causes driving member distortion, the asynchronous and medium partially problem of handcart.Land lever propulsive mechanism and handcart split, handcart into and out of not steady, top easily produces the hypsokinesis phenomenon, and the insertion depth instability of moving contact, operation is also inconvenient.
Task of the present utility model provides the handcart advancing mechanism of a kind of fltting speed handcart type high-voltage switch cabinet fast and easy and simple to handle.
Task of the present utility model is to realize by following approach: the handcart advancing mechanism of the handcart type high-voltage switch cabinet that is provided is positioned at hand lever on the switch cabinet body by a pair of connecting rod, the fulcrum shaft that is hinged on the handcart both sides respectively and the guide post of handcart is formed, wherein hand lever is divided into handgrip and connecting lever two parts from fulcrum, this connecting lever and aforesaid connecting rod are hinged by bearing pin, one end of handcart guide post links to each other with switch cabinet body, and the other end places among the fairlead of handcart.When hand lever when its fulcrum shaft rotates, by connecting rod handcart is moved, thereby realize the propelling of handcart or pull out.
The utility model is simple in structure, owing to adopt lever, and drive handcart by the connecting rod of handcart both sides, so transmission link is few, fltting speed is quick and labour-saving, is provided with the handcart guide post in addition, make moving steadily of handcart, and better to neutrality, guaranteed the reliable contact of contact.
Below in conjunction with accompanying drawing content of the present utility model is described in detail.
Fig. 1 is the structure diagram of an embodiment of the utility model.
Fig. 2 is the structure chart of hand lever fulcrum shaft part among Fig. 1.
As shown in Figure 1: each hinged connecting rod 2 of the both sides of handcart 1, each connecting rod 2 is hinged with a connecting lever 3 respectively again.Connecting lever 3 is connected as a single entity with handgrip 4, constitutes a hand lever 5, and the two ends of its fulcrum shaft 6 are inserted in the both sides of switch cabinet body 7.One end of handcart guide post 8 is inserted among the handcart fairlead 9, and the other end is fixed on the support 10 of fulcrum shaft 6 with thread connecting mode.When upwards promoting handgrip 4, connecting lever 3 inhour is downwards swung, and moves to right by connecting rod 2 drive handcarts 1, and the position of handcart is shown in double dot dash line among the figure at this moment.This position is handcart " test " position.Handcart 1 moves to left when handgrip 4 rotates clockwise, until " service position " of handcart.Pin joint when handcart is in " service position " between connecting rod 2 and the connecting lever 3 cross two fulcrum shaft lines 11 some, its position is limited by the guide vane end stop 12 of connecting lever 3, can prevent like this handcart when the service position because of retreated by electrodynamic effect.
For flexibly connecting, its structure as shown in Figure 2 between the fulcrum shaft 6 of previous manual lever 5 and the cabinet 7.The fulcrum shaft 6 of hand lever is contained in by one that hollow shaft 13 on the support 10, two axially insert slip lock pin 14 in this hollow shaft and the operating mechanism of this lock pin is formed.Wherein the connecting lever 3 of hand lever connects firmly on this hollow shaft 13 by pin; Lock pin 14 operating mechanisms are enclosed within hollow shaft 13 outer sliding sleeve 15 and actuating linkages 16 by two and form, two sliding sleeves 15 connect firmly (being connected with pin) with two slip lock pins 14 respectively, and the while is that the center symmetry is hinged on the actuating linkage 16 with the fulcrum shaft 17 of actuating linkage respectively again; The part that lock pin 14 stretches out hollow shaft 13 is inserted in the seat hole 18 of switch cabinet body 7.For sliding sleeve 15 is slided flexibly, sliding sleeve is unsuitable oversize, and therefore each has fixed the extension of a fishplate bar 19 as sliding sleeve 15 on two sliding sleeves 15, and then fishplate bar 19 is hinged on the actuating linkage 16.Promote actuating linkage 16 sliding sleeve 15 is moved, stretch, contract thereby drive lock pin 14.Certainly on hollow shaft 13, also need offer lock pin is connected pin 20 with sliding sleeve chute 21.After lock pin 14 stretches out and inserts cabinet seat hole 18, handle the handgrip 4 on the hollow shaft 13, hollow shaft 13 is rotated, and drive connecting lever 3, realize the propelling of handcart or pull out.After lock pin 14 withdrawals, promptly to separate with cabinet 7, can together pull out switch cubicle together with support 10 with handcart and overhaul this moment.
