Description

Mining transformer closing device

Technical Field

The utility model relates to a mining transformer closing device.

Background

The mining transformer is a complete set of movable power supply and transformation devices used in mines, the existing mining transformer is lack of a fixing device in the length direction, so that the transformer is easy to loosen in the length direction, the passing rate of an emergent short circuit test is low, the safety and reliability are low, and further improvement is needed.

SUMMERY OF THE UTILITY MODEL

To the current situation of above-mentioned prior art, the utility model aims to solve the technical problem that a can prevent that the transformer from taking place not hard up in order to improve the passing rate and the fail safe nature of proruption short circuit test, and convenient operation's mining transformer closing device in length direction side is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the mining transformer pressing device is characterized by comprising a body and rivets; the rivet comprises four rivets, wherein the four rivets are arranged in a pairwise symmetrical manner and are detachably arranged in a body, four through holes which are distributed in a pairwise symmetrical manner are formed in the body, a vertically distributed slotted hole is formed in the inner wall of the upper side of each through hole, convex edges which are symmetrically and vertically distributed are outwards formed on the left side and the right side of each slotted hole, and an inclined plane is formed at the lower end of each convex edge; the outer diameter of the threaded end of the rivet is matched with the width of the groove hole, and the outer diameter of the head of the rivet is matched with the inner diameter of the through hole.

Preferably, the left side and the right side of the body are both outwards formed with flanging which are symmetrically distributed mutually.

Compared with the prior art, the utility model has the advantages of: the utility model discloses can be simple quick fix the transformer in order to prevent that the transformer from taking place not hard up in length direction side at length direction to improve the throughput rate and the fail safe nature of proruption short circuit test, and convenient operation.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1-4, the mining transformer pressing device comprises a body 2 and a rivet 3; the four rivets 3 are symmetrically arranged in pairs and detachably arranged in the body 2, two flanges 21 which are symmetrically distributed with each other are outwards formed on the left side and the right side of the body 2 to increase the strength, four through holes 22 which are symmetrically distributed with each other in pairs are formed in the body 2, a vertically distributed slotted hole 23 is formed in the inner wall of the upper side of each through hole 22, two symmetrical and vertically distributed convex edges 24 are outwards formed on the left side and the right side of each slotted hole 23, and an inclined plane 25 is formed at the lower end of each convex edge 24; the outer diameter of the threaded end of the rivet 3 is matched with the width of the slot 23, and the outer diameter of the head of the rivet 3 is matched with the inner diameter of the through hole 22.

One end of each of the four rivets 3 is fixed on one length side of the transformer 1 in advance, the positions of the four rivets 3 are matched with the positions of the four through holes 22, when the transformer is used, one body 2 is vertically arranged outside one side of the transformer 1, the four through holes 22 are sleeved outside the four rivets 3 respectively, then the body 2 is slowly pressed down to vertically slide down, two inclined planes 25 at each through hole 22 are inserted into the inner sides of the heads of the rivets 3, finally, the two convex edges 24 are inserted into the inner sides of the heads of the rivets 3, the rivets 3 are pushed out by the heads of the rivets 3 to clamp the left side and the right side of the transformer 1, the threaded ends of the rivets 3 are inserted into the slotted holes 23, and therefore, one body 2 is detachably fixed on one side of the transformer 1, and then, the other body 2 is fixed according to the same principle; during disassembly, the body 2 is lifted up, so that the head of the rivet 3 slides away from the flange 24 until the threaded end of the rivet 3 enters the through hole 22 from the slot 23.

The utility model discloses can be simple quick fix the transformer in order to prevent that the transformer from taking place not hard up in length direction side at length direction to improve the throughput rate and the fail safe nature of proruption short circuit test, and convenient operation.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
