Abstract
The utility model relates to a substation car torque crank, belonging to the technical field of power supply equipment. The technical scheme is that the substation car torque crank comprises a torque wrench (1), a handle (2), a ratchet head (4) and a car crank sleeve port (5), the handle (2) is arranged on the upper part of the torque wrench (1) and is fixedly connected with the torque wrench (1) by welding, the ratchet head (4) is arranged on the lower part of the torque wrench (1), and the car handle sleeve port (5) can be inserted into the ratchet head (4). The substation car torque crank has the advantages that the structure is simple, the cost of operation and maintenance is low, the use of the substation car torque crank is simple and clear, the moment magnitude of a substation car crank can be controlled, the damage of a substation car switch cabinet mechanical transmission device caused by different forces of different operators is prevented, and the safe operation of substation equipment is ensured.
Description
Technical field
The utility model relates to a kind of transformer station dolly moment of torsion crank, belongs to the power supply unit technical field.
Background technology
At present the 10kV of transformer station of power supply enterprise electric pressure great majority adopt trolley types, and it is also more and more that 35kV electric pressure trolley type switch cubicle is used, thus transformer station has a power failure or during maintenance the number of times of operation car switch cabinet more and more.Operation car switch cabinet dolly must be used crank.Because now the dolly crank all is manual operation, so in the grasp of the dynamics of crank, because operating personnel's difference and bad student's difference.The car switch cabinet can produce catching phenomenon owing to reason or mechanical latching reason are installed in the process of operation dolly crank, if this moment is firmly excessive, can cause damage to car switch cabinet-type air conditioner tool transmission device.
The utility model content
The utility model purpose provides a kind of transformer station dolly moment of torsion crank, by adopting the crank that to control transformer station's dolly crank moment, avoid excessive car switch cabinet-type air conditioner tool transmission device being caused damage because exerting oneself, solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: a kind of transformer station dolly moment of torsion crank, comprise torque wrench, handle, ratchet head and dolly crank running-on, described handle is arranged on the top of torque wrench, be fixedly connected by welding with torque wrench, ratchet head is arranged on the bottom of torque wrench, and dolly crank running-on is arranged in the ratchet head insertedly.
Also comprise direction conversion ring, described direction conversion ring is arranged between torque wrench and the ratchet head.
The beneficial effects of the utility model are: simple in structure, operation and maintenance cost is low, use simple and clear, can control the moment size of transformer station's dolly crank, prevent from exerting oneself different because of different operating personnel, cause transformer station's car switch cabinet-type air conditioner tool transmission device is caused damage, thus the safe operation of assurance substation equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: torque wrench 1, handle 2, direction conversion ring 3, ratchet head 4, dolly crank running-on 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of transformer station dolly moment of torsion crank, comprise torque wrench 1, handle 2, ratchet head 4 and dolly crank running-on 5, described handle 2 is arranged on the top of torque wrench 1, be fixedly connected by welding with torque wrench 1, ratchet head 4 is arranged on the bottom of torque wrench 1, and dolly crank running-on 5 is arranged in the ratchet head 4 insertedly.
Also comprise direction conversion ring 3, described direction conversion ring 3 is arranged between torque wrench 1 and the ratchet head 4.
In use, set the moment size by torque wrench 1, proofread and correct direction of the present utility model by direction conversion ring 3, dolly crank running-on 5 inserts ratchet head 4, the other end of dolly crank running-on 5 inserts transformer station's car switch cabinet dolly jack, shake handle 2, dolly is operated, when dolly runs into mechanical clamping stagnation, when moment surpasses torque wrench 1 set point, torque wrench 1 sends " click is rattled away ", and each rings, and prompting the utility model has surpassed the moment of normal need, needs operating personnel to check whether dolly is unusual.
Claims (2)
1. transformer station's dolly moment of torsion crank, it is characterized in that: comprise torque wrench (1), handle (2), ratchet head (4) and dolly crank running-on (5), described handle (2) is arranged on the top of torque wrench (1), be fixedly connected by welding with torque wrench (1), ratchet head (4) is arranged on the bottom of torque wrench (1), and dolly crank running-on (5) is arranged in the ratchet head (4) insertedly.
