Description
Technical field
The utility model relates to a kind of new and effective extension spring frock.
Background technology
Primary cut-out is responsible for the overload of power equipment in high-voltage power supply and distribution system, the protection such as short circuit and the important task controlled, at present, in 6-24kV indoor high-voltage circuit breaker is manufactured, dominant position is accounted for the circuit breaker that VS1 mechanism is operating mechanism, thus each circuit breaker manufacturing enterprise is classified as the improvement of the optimization of mechanism and mechanism's assembly technology as the most important thing, the main method adopted of present stage VS1 mechanism combined floodgate spring assembling is: the one end first fixing combined floodgate spring, by wear hook or iron wire on frame process hole after, the other end of combined floodgate spring is moved to the method for fixing again steady pin position with lever or small-sized machine, the method has following deficiency: 1, time-consuming, in normal assembling, when hanging combined floodgate spring, first at non-stiff end hook or iron wire to be twined, being hung over by the fabrication hole on framework exerts all one's strength on lever or apparatus again, whole process duration, 2, require great effort, whole extension spring operates a people and cannot complete, and needs to assist, and what more have can not complete on normal streamline, just can complete under needing to forward specific region or line week to, 3, security reliability is poor, because iron wire or to link up with drawing brake spring all just complementary, occurs unavoidably breaking off relations or the situation of iron wire fracture, more likely hurt operating personnel, therefore, be necessary to improve in drawing brake spring process.
Utility model content
The technical problem that the utility model solves: a kind of new and effective extension spring frock is provided, adopt lever principle, bracket inserts combined floodgate spring lower end from after the gap that port 2-3 encloses, upwards lifting handle makes handle by bracket, combined floodgate spring lower end is pulled to installation site centered by hinged place, steady pin afterwards by being equipped with block card is installed fixing, structure is simple, easy to operate, time saving and energy saving, alleviate working strength and the operating pressure of operating personnel, maintain the integrality of streamline simultaneously, greatly save installation cost.
The technical solution adopted in the utility model: new and effective extension spring frock, comprise support bar, handle and bracket, end, described handle upper end is fixedly connected with bracket, described handle upper end is provided with wins in succession and one end of winning in succession is fixedly connected with handle, the described other end and the post upper of winning in succession is articulated as one by articulated elements, described support bar lower end is provided with the connector that large bent plate inwall supports with framework, lift after handle makes combined floodgate spring lower end aim at fixed position on described bracket insertion combined floodgate spring lower end is backward from the gap that port 2-3 encloses and by the steady pin that block card is housed, combined floodgate spring lower end is fixed.
Wherein, in described bracket, top is shaped with U-shaped mouth and its lower end is connected with handle upper end end winding support.
Further, described connector is holding screw or fastening bolt, and described support bar lower end is shaped with screwed hole and connector and screwed hole screw and stretch out screwed hole.
Further, described articulated elements is pin or bolt.
The utility model advantage compared with prior art:
1, adopt the involutory brake spring lower end of lever principle to carry out installation to fix, alleviate working strength and the operating pressure of staff, time saving and energy saving;
2, bracket is shaped with U-shaped mouth, substantially increases the reliability that bracket inserts combined floodgate spring, eliminate the possibility of bracket slippage, simple and compact for structure, safe and reliable;
3, combined floodgate spring installs convenient fixing fast, and whole installation process completes on normal streamline, installs, ensure that the integrality of streamline, greatly saved assembly cost under being forwarded to specific region or line its week.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure left view.
Embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
New and effective extension spring frock, comprise support bar 1, handle 2 and bracket 3, end, described handle 2 upper end is fixedly connected with bracket 3, described handle 2 upper end be provided with win in succession 4 and 4 one end of winning in succession be fixedly connected with handle 2, described 4 other ends and support bar 1 upper end of winning in succession is articulated as one by articulated elements 7, described support bar 1 lower end is provided with the connector 5 that large bent plate inwall supports with framework, described bracket 3 insert combined floodgate spring lower end backward from the gap that port 2-3 encloses on lift after handle 2 makes combined floodgate spring lower end aim at fixed position and by the steady pin that block card is housed, combined floodgate spring lower end fixed, in described bracket 3, top is shaped with U-shaped mouth 6 and its lower end is connected with handle 2 upper end end winding support, described connector 5 is holding screw or fastening bolt, and described support bar 1 lower end is shaped with screwed hole and connector 5 and screwed hole screw and stretch out screwed hole, described articulated elements 7 is pin or bolt.
During use, first combined floodgate spring upper end is fixed on the energy-storage crank arm in framework, then to put into after block card and steady pin being installed on chassis base and to be located at side, combined floodgate spring installation site, afterwards bracket 3 is inserted combined floodgate spring lower end from the gap that port 2-3 encloses, finally support bar 1 lower end is supported on the large bent plate inwall of framework, afterwards handle 2 is upwards lifted, utilize lever principle, support bar 1 and handle 2 hinged place move downward to bracket 3, in the process of motion, combined floodgate spring is pulled to installation site downwards, after combined floodgate spring is aimed at the installation site of framework bottom surface, be fixed by steady pin, complete the installation of combined floodgate spring, structure is simple, operating personnel are easy to operation, and installation process is time saving and energy saving, while improve efficiency of assembling, alleviate working strength and the operating pressure of operating personnel, also the integrality of streamline is maintained, greatly save assembly cost.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
