Description
Technical Field
The invention relates to the technical field of maintenance of power transmission and transformation power equipment, in particular to a locking device for a door handle of a converter transformer substation cabinet.
Background
In the current conversion transformer substation, there are a large amount of cabinets, and some cabinets are equipped with the handle, and the cabinet door can be opened to rotatory handle, but some cabinets can not be opened at will, if the maintainer is in the maintenance in-process, opens electrified cabinet at will, probably causes accidents such as personnel's electric shock or equipment tripping operation.
Disclosure of Invention
The invention aims to provide a locking device for a cabinet door handle of a converter transformer substation, which can effectively prevent a person from rotating the cabinet handle at will to open a cabinet door under the condition of locking, and has the advantages of simple structure and convenience and reliability in use.
In order to solve the technical problem, the invention adopts the following technical scheme:
the invention relates to a locking device for a door handle of a converter substation cabinet, which comprises an L-shaped first component and an L-shaped second component, wherein one end of the first component is hinged with one end of the second component, the end of the first component, which is far away from the hinged end, is a bent end, which enables the first component to form an L shape, the bent side end of the second component is provided with a first lock hole, and a second lock hole is arranged at the position, opposite to the first lock hole, of the first component; the bending end of the first component is also provided with a U-shaped groove for facilitating the tail of the door handle to pass through, and the second component is also provided with a plurality of screw holes for fixing.
Furthermore, the first lock hole and the second lock hole are respectively arranged on the folded plate at the corresponding positions of the first part and the second part.
Further, the folded plate is formed by bending or fixed by welding.
Furthermore, the second part is provided with 3 evenly distributed screw holes for fixing.
Further, the first part and the second part are connected by a hinge.
Furthermore, the first component and the second component are both made of stainless steel.
Compared with the prior art, the invention has the beneficial technical effects that:
the device can lock and fix the door handle of the cabinet, prevent personnel from opening the cabinet door at will and achieve the purpose of preventing the personnel from getting an electric shock or equipment tripping accidents caused by mistaken opening of the cabinet door. The device is simple to install, convenient to maintain, durable and high in practicability.
Drawings
The invention is further illustrated in the following description with reference to the drawings.
Fig. 1 is a schematic structural diagram of a locking device of a cabinet door handle of a converter transformer substation according to the present invention;
description of the reference numerals: 1. a first member; 2. a second component; 3. loose leaves; 4. a first lock aperture; 5. a second lock aperture; 6. a U-shaped groove; 7. a screw hole; 8. and (5) folding the board.
Detailed Description
As shown in fig. 1, a converter substation cabinet door handle locking device includes an L-shaped first part 1 and an L-shaped second part 2, both of which are made of stainless steel, wherein one end of the first part 1 is hinged to one end of the second part 2 through a hinge, and meanwhile, one end of the first part 1, which is away from the hinged end, is a bent end (bent at 90 degrees) for forming the L-shape of the first part 1, a first lock hole 4 is formed at a bent side end of the second part 2, and a second lock hole 5 is formed at a position of the first part 1, which is opposite to the first lock hole 4; the bending end of the first component 1 is also provided with a U-shaped groove 6 for facilitating the tail of the door handle to pass through, and the second component 2 is also provided with 3 screw holes 7 for fixing.
First tool to lock hole 4 and second tool to lock hole 5 set up respectively in folded plate 8 on first part 1 and the corresponding position of second part 2, folded plate 8 is buckled the shaping or welded fastening, and it is in order to guarantee that two folded plates are parallel relatively for setting up perpendicularly.
The specific implementation steps are as follows:
the second part 2 and the first part 1 are connected together through a loose leaf, and after the second part 2 and the first part 1 are connected, the second part 2 and the first part 1 rotate through the loose leaf;
the second component 2 is fixed below the door handle through screws, rivets or super glue, and when the second component 2 is fixed, the distance between the first component 1 and the door handle is adjusted, so that the tail part of the door handle passes through the U-shaped groove 7 of the first component 1, and the second component 2 and the lockset hole of the first component 1 are overlapped;
when the door handle is in normal operation, a lockset passes through the lockset holes of the second component 2 and the first component 1 to be locked, and the door handle cannot be rotated to open the door because the door handle is clamped by the U-shaped groove of the first component 1; when the maintenance work, take off the tool to lock, put down first part 1 through the loose-leaf for the U-shaped groove of first part 1 can not block the door handle, thereby can rotate the door handle and open the door.
The above-described embodiments are only intended to illustrate the preferred embodiments of the present invention, and not to limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
