Description
Technical Field
The utility model relates to a five-prevention lockset for a coal mine underground high-explosion switch, and belongs to the technical field of five-prevention locksets for coal mine underground high-explosion switches.
Background
China is a large country for coal production in the world, and the coal yield occupies the first place in the world. With the expansion of the high-yield and high-efficiency production scale of the coal mine, comprehensive mechanical and intelligent coal mining processes are applied, underground coal mine electrical equipment is more and more, and according to related regulation requirements such as coal mine safety regulations, a five-prevention lock is required to be configured for a high-explosion switch, and an operator is forced to correctly overhaul the electrical equipment according to a given safe operation sequence by the lock, so that electric shock accidents caused by misoperation are avoided. When the existing five-prevention lock for the high-explosion switch adopts a shielding plate mode, when the electric overhaul is performed, only an operator opens the lock by using a special key to lift the shielding plate, the screw of the end cover of the high-explosion switch can be exposed, the screw is screwed off, and after the end cover is taken off, the overhauling operation can be performed on the side of the power supply and the load side of the high-explosion switch, but because the underground environment of a coal mine is severe, the existing five-prevention lock is fixedly combined with the surface of the end cover of the high-explosion switch in a pasting mode, and after a period of use, the lock falls off or loosens, the service life is short, so that the five-prevention lock cannot have the due safety effect.
Disclosure of Invention
The utility model aims to provide a five-prevention lockset for a coal mine underground high-explosion switch, which is safe, reliable, free from falling and long in service time.
In order to achieve the above object, the present utility model includes: padlock, connecting piece, fastening screw, the connecting piece sets up to the groove structure, and open respectively at the both ends of connecting piece has the lockhole of wearing, and open in the middle of the recess of connecting piece has the wire hole of wearing, and fastening screw passes the wire hole of wearing, and the padlock passes two lockholes of wearing and locks on the connecting piece.
The two ends of the connecting piece are arranged to be arc-shaped structures.
When the explosion-proof end cover is used, firstly, the padlock is opened by using a key, then a fastening screw is screwed in a screw hole on the explosion-proof switch end cover by using a screwing tool, so that the end cover and the explosion-proof switch are integrated, then the padlock is locked on a connecting piece by penetrating through a locking hole, and finally, the explosion-proof switch end cover is respectively arranged at two opposite angles on the explosion-proof switch end cover, so that the whole explosion-proof switch end cover mounting work is completed. Because the padlock blocks the fastening screw, an operator can open the end cover to overhaul equipment only by using a special key and a screwing tool, so that the damage to personnel and equipment caused by misoperation of other personnel is effectively prevented, and the device has the characteristics of safety, reliability, no falling, long service time and the like.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic front view of the connector of the present utility model;
FIG. 3 is a schematic left-hand structural view of the connector of the present utility model;
fig. 4 is a schematic top view of the connector of the present utility model.
The reference numerals are explained as follows:
1-padlock; a 2-connector; 3-fastening a screw; 4-penetrating a lock hole; 5-threading holes.
Description of the embodiments
The utility model is described in further detail below with reference to the accompanying drawings.
As can be seen from fig. 1, 2, 3 and 4, the present utility model includes: padlock 1, connecting piece 2, fastening screw 3, the connecting piece sets up to the groove structure, can adopt the steel sheet shearing press forming. The two ends of the connecting piece are respectively provided with a penetrating lock hole 4, and the size of the penetrating lock hole is matched with the diameter of the lock ring of the padlock so that the lock ring can smoothly penetrate. A threading hole 5 is formed in the middle of the groove of the connecting piece, the fastening screw penetrates through the threading hole, the size of the threading hole is matched with that of the fastening screw, the rod body thread part of the fastening screw can pass through the threading hole, the large end of the fastening screw cannot pass through the threading hole, and the rod body thread part of the fastening screw is matched with the screw hole on the end cover of the high-explosion switch. The lock ring of the padlock passes through the two through lock holes to be locked on the connecting piece, the padlock can block the large end of the fastening screw, the protection effect is achieved, and the padlock cannot be opened without a special key. The two ends of the connecting piece are arranged into arc structures, so that injuries of rough edges and corners to hands can be avoided.
In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed" and "mounted" are to be construed broadly, and may be, for example, fixed or removable; the specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
All other embodiments, modifications, equivalents, improvements, etc., which are apparent to those skilled in the art without the benefit of this disclosure, are intended to be included within the scope of this utility model.
