Abstract
The utility model discloses a closing coil overhaul support which mainly solves the problems that when a closing coil of an electromagnetic mechanism is replaced, because an iron core and an outer shell of the closing coil are heavy iron pieces with irregular shapes, a proper acting point of the closing coil is difficult to find and disassembly and assembly waste time and labor. The closing coil overhaul support comprises a supporting platform and a hydraulic lifter, wherein a groove is formed in the bottom of the hydraulic lifter, the top of the lifting part of the hydraulic lifter is arranged in the groove and connected with the supporting platform, and the hydraulic lifter comprises a base, a large oil cylinder, a large piston, a small oil cylinder, a small piston, an oil storage tank, a handle, a large oil cylinder one-way valve, a small oil cylinder one-way valve and an oil return valve rod. When the closing coil needs replacing, a worker only needs to place an auxiliary support under the outer shell of the closing coil, close an oil return valve, and lift up and press down the handle of the hydraulic lifter to make the large piston ascend and drive the supporting platform to ascend to the closing coil, and then the heavy outer shell of the closing coil can be easily disassembled and assembled. The closing coil overhaul support is simple in structure, convenient to use and low in cost, saves labor and improves the replacement speed.
Description
Technical field
The utility model relates to a kind of closing coil repairing auxiliary device, specifically a kind of closing coil maintenance support.
Background technology
Circuit breaker is a kind of of on-load switch, has short circuit and overload protection function, and its short-circuit protection function is realized by closing coil.Perfect because of its defencive function, maintenance, easy to use, so be widely used in electric system.
Closing coil is the core component of electric switch-on in primary cutoff part, uses the hollow cylindrical coil that has that copper cash is coiled into.But, at primary cutoff, burn out need to change electromagnetic mechanism closing coil time, because closing coil iron core and shell are that ironware weight is large and shape is lofty, while causing changing, to put forth effort nowhere, dismounting is relatively wasted time and energy.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of closing coil maintenance support, can solve the problem wasting time and energy when existing closing coil is changed.
The technical scheme in the invention for solving the technical problem is: a kind of closing coil maintenance support, it is characterized in that, comprise support platform and hydraulic pressure lifting device, described support platform bottom is provided with groove, and the lifting part top of described hydraulic pressure lifting device is arranged in groove and is connected with support platform;
Described hydraulic pressure lifting device comprises base, large tank, large piston, small oil tank, valve piston, petrol storage tank, handle, large tank check valve, small oil tank check valve and oil return valve rod; The described large tank that is provided with large piston is separately positioned on base with the small oil tank that is provided with valve piston, in described large tank shell, is provided with petrol storage tank; Described petrol storage tank is communicated with small oil tank check valve by pipeline, and is unilaterally connected from petrol storage tank to small oil tank; Described small oil tank is communicated with large tank check valve by pipeline, and is unilaterally connected from small oil tank to large tank; Between described large tank and petrol storage tank, be provided with oil return line, described oil return valve rod one end is connected with the valve of oil return line, and the other end is arranged on base exterior; Described handle is anterior to be connected with valve piston top, and the front end strong point is arranged on large tank shell.
Preferably, described support platform is square platform.
The beneficial effects of the utility model are: adopt after said structure, when needs are changed closing coil, only auxiliary stand described in the utility model need be placed under closing coil shell, close oil return valve, lift up and down and press the handle of hydraulic pressure lifting device make large piston increase and drive support platform to be increased to coil place, coil is placed in support platform, can the larger coil case of light dismounting weight.The utility model is not only simple in structure, easy to use, and cost is low, saves manpower, has accelerated replacing speed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1 support platform, 2 hydraulic pressure lifting devices, 201 bases, 202 large tanks, 203 large pistons, 204 small oil tanks, 205 valve pistons, 206 petrol storage tanks, 207 handles, 208 large tank check valves, 209 small oil tank check valves, 210 oil return valve rods.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of closing coil maintenance support of the present utility model, it comprises support platform 1 and hydraulic pressure lifting device 2, described support platform 1 bottom is for being provided with the square platform of groove.Described hydraulic pressure lifting device 2 comprises base 201, large tank 202, large piston 203, small oil tank 204, valve piston 205, petrol storage tank 206, handle 207, large tank check valve 208, small oil tank check valve 209 and oil return valve rod 210; The described large tank 202 that is provided with large piston 203 is separately positioned on base 201 with the small oil tank 204 that is provided with valve piston 205, in described large tank 202 shells, is provided with petrol storage tank 206; Described petrol storage tank 206 is communicated with small oil tank check valve 209 by pipeline, and to small oil tank 204, is unilaterally connected from petrol storage tank 206; Described small oil tank 204 is communicated with large tank 202 check valves by pipeline, and to large tank 202, is unilaterally connected from small oil tank 204; Between described large tank 202 and petrol storage tank 206, be provided with oil return line, described oil return valve rod 210 one end are connected with the valve of oil return line, and the other end is arranged on base 201 outsides; Described handle 207 is anterior to be connected with valve piston 205 tops, and the front end strong point is arranged on large tank 202 shells; The top of described large piston 203 is arranged in groove and is connected with support platform 1.
When needs are changed closing coil, only auxiliary stand described in the utility model need be placed under closing coil shell, close oil return valve 201, upwards lift the handle 207 of hydraulic pressure lifting device, thereby make valve piston 205 upward movements form parital vacuum, fluid is inhaled into small oil tank 204 from petrol storage tank 206 by small oil tank check valve 209, then pressing down handle 207 presses down valve piston 205, hydraulic oil in small oil tank 204 is pressed in large tank 202 by large tank check valve 208, thereby promote the moving support platform 1 of shipper pole on large piston 203 and be increased to coil place, coil is placed in support platform 1, can the larger coil case of light dismounting weight.After changing closing coil, reverse back fuel tap bar 210, be communicated with large tank 202 and petrol storage tank 206, large tank inner fluid directly flows back to petrol storage tank 206, and large piston 203 falls, thereby support platform 1 is fallen after rise.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
