Abstract
The utility model relates to a mounting instrument for a switch-on spring of a vacuum circuit breaker, which consists of a crow bar (1), a connecting rod (6), a stress rod (4) and a support frame (5), wherein one end of the crow bar is a U-shaped crow plate (2) while the other part is a handle (3), one end of the connecting rod (6) is connected with the crow bar (1) by welding while the other end is connected with the stress rod (5) through a shaft pin (4), and the support frame (5) is arranged at the tail end of the stress rod (4). The mounting instrument has the advantages of strong practicability, simple operation, time-saving and labor-saving properties and low cost, and the works of mounting and dismantling the switch-on spring can be completed only by one person.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker Installation and Debugging instrument, relates in particular to a kind of erecting tools of vacuum circuit-breaker switching-in spring, specifically a kind of middle installation, adjustment instrument of pressing vacuum circuit-breaker operating mechanism energy-stored spring.
Background technology
Switching-in spring claims to release the energy spring again, it is the core component in the vacuum circuit-breaker, the conventional method of its installation and removal is with iron wire the one end to be sling admittedly earlier, prizes forward with the iron rod insertion spring space end of a lever character then, elongates desired location and is fixed with bolt; Can discharge very big strength because of spring during its dismounting, can not directly dismantle the bolt of an end, need with iron wire the one end to be sling admittedly earlier, tear bolt again open, slowly switching-in spring be put down.This installation method is wasted time and energy, need a plurality of staff's cooperation just can finish, not enough or error occurs as staff's active force when the operation, release can spring do not move to the position again bounce-back go back, because of releasing the huge energy of energy spring, cause operating personnel injured easily.
The utility model content
For solving the defective that above-mentioned technology exists, the utility model provides a kind of erecting tools of vacuum circuit-breaker switching-in spring, this kind erecting tools is practical, simple to operate, time saving and energy saving, with low cost, and one man operation just can be finished the work of installation and removal switching-in spring.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of erecting tools of vacuum circuit-breaker switching-in spring, form by sledge thick stick (1), connecting rod (6), force rod (4), bracing frame (5), it is characterized in that: sledge thick stick one end is that U-shaped skid plate (2), remainder are handle (3), connecting rod (6) one ends are connected with sledge thick stick (1) by welding, the other end is connected with force rod (5) by pivot pin (4), and the tail end of force rod (4) is equipped with bracing frame (5).
The utility model material is all the metal steel.
Advantage of the present utility model:
1. simple in structure, practical.
2. cheap for manufacturing cost.
3. simple to operate, time saving and energy saving, one man operation just can be finished the work of installation and removal switching-in spring, has improved operating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a vertical view cutaway drawing of the present utility model;
Fig. 3 is a fundamental diagram of the present utility model.
Marginal data:
Crowbar (1), handle (3), U-shaped skid plate (2), pivot pin (4), force rod (5), bracing frame (6), connecting rod (7), switching-in spring (8), mechanism (9).
Embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings.
One end of switching-in spring (8) is installed on mechanism's connecting lever by bolt, U type skid plate of the present utility model (2) will be inserted into the gap of switching-in spring (8) other end then, bracing frame (6) is placed on the top of mechanism (9) framework upper limb inboard, manually hold handle (3) application of force downwards, the position that switching-in spring (8) is moved to required mount, insert to be fixed with fixing pivot pin again and get final product, the whole operation process is simply laborsaving.
Claims (1)
