The work causes serious potential safety hazards to daily mutual inductor verification work of a metering room, and causes the accidents of slight injury of multiple persons and appearance damage of the mutual inductor at present. The working efficiency and the laboratory safety index of the mutual inductor are seriously influenced. Therefore, in order to solve the problems, a mutual inductor hoisting device is urgently needed to be developed, and personal and equipment safety is guaranteed.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a laboratory mutual-inductor stone tongs uses with the cooperation of indoor hoisting equipment, is applicable to the high-voltage transformer hoist and mount of different grade type, different shapes.

The utility model discloses a realize like this, a laboratory mutual-inductor stone tongs, including motor case and the splint of rotationally symmetrical connection in motor case both sides, motor incasement portion sets up the motor, stretches out the axis of rotation on the motor, and the axis of rotation stretches out from the motor case lower extreme, and is equipped with 2 at least winding grooves on the axis of rotation, twines the rigidity rope respectively in the winding groove, and the other end of rigidity rope is connected with two splint inboards respectively, between two splint and motor case surface, connects the supporting spring respectively, is used for supporting splint; the splint is L-shaped.

Furthermore, the motor case is connected with the position of the supporting spring, and is respectively provided with a guide fixing groove, the supporting spring is arranged in the guide fixing groove, and the guide fixing groove is obliquely arranged upwards.

Furthermore, a switch is arranged on the motor box to control the starting and the closing of the motor, and a storage battery is arranged in the motor to supply power to the motor.

Furthermore, a hanging ring is fixed at the top end of the motor box and used for being connected with hoisting equipment.

Further, the fixture is far away from a fixing baffle at the edge of one end of the motor box and used for preventing the mutual inductor from sliding off in the clamping process.

Compared with the prior art, the utility model has the advantages of: in the process of detecting the mutual inductor in a laboratory, the mutual inductor can be safely and reliably lifted to a laboratory bench from the ground, so that labor is saved, and danger is prevented.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and embodiments:

fig. 1 is a schematic structural view of the state of the mutual inductor which is not clamped by the utility model;

fig. 2 is the utility model discloses press from both sides the structure schematic diagram of getting the mutual-inductor state.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, the utility model provides a laboratory mutual inductor stone tongs, including motor case 1 and splint 2 rotationally and symmetrically connected in motor case 1 both sides, motor 3 is fixed to be set up in motor case 1, the axis of rotation stretches out on motor 3, the axis of rotation stretches out from motor case 1 lower extreme, and is equipped with 2 kinking grooves 5 on the axis of rotation, twine rigid rope 6 respectively in kinking groove 5, the other end of rigid rope 6 is connected with two splint 2 inboard respectively, between two splint 2 and motor case 1 surface, connect supporting spring 7 respectively, be used for supporting splint 2; the splint 2 is L-shaped.

When the mutual inductor is identified in a laboratory, the novel transformer is connected with hoisting equipment, when the novel transformer is lowered to the position of the mutual inductor, the motor 3 is opened, the motor 3 drives the rotating shaft to rotate, the rigid rope 6 is wound on the rotating shaft in the rotating process of the rotating shaft, so that the two clamping plates 2 are drawn close, 2 winding grooves 5 are arranged in the embodiment, in order to prevent the two clamping plates 2 from being unevenly stressed due to the fact that the rigid rope 6 is not arranged in the center of the clamping plates 2 in the pulling process, the number of the winding grooves 5 and the rigid rope 6 can be 4, each clamping plate 2 is pulled through the two rigid ropes 6, the other ends of the two clamping plates 2 extend into the lower parts (refer to figure 2) of two primary terminals of the mutual inductor, after the clamping, the clamping device clamps together with the mutual inductor are clamped by the hoisting equipment, after the mutual inductor is placed on a laboratory bench, the motor 3 drives the rotating shaft to rotate, the two clamping plates 2 are sprung up, thereby releasing the instrument transformer.

In order to prevent that supporting spring 7's position is difficult to fixed, unable normal bounce splint 2, as technical scheme's improvement, on motor case 1 connects supporting spring 7's the position, set up direction fixed slot 8 respectively, supporting spring 7 sets up in direction fixed slot 8, and direction fixed slot 8 sets up in the slant. The bottom ends of the supporting springs 7 are connected in the guide fixing grooves 8, and other positions are only attached to the guide fixing grooves 8 and are not connected.

In order to realize the control of the motor 3, preferably, a switch is arranged on the motor box 1 to control the starting and the closing of the motor 3, and a storage battery is arranged in the motor 3 to supply power to the motor 3.
