Abstract
The utility model relates to an isolating switch safety lock used for a coal mining working face. The existing eight-combined switch can not ensure that the same person cuts off the power and supplies the power. The isolating switch safety lock used for the coal mining working face comprises a lock body, a lock pin, and a coded lock; wherein a main body of the lock body is in a flat cuboid shape and is provided with a longitudinal pinhole and a vertical through hole, an axis of the longitudinal pinhole and an axis of the vertical through hole are vertically intersected; an internal diameter of the vertical through hole is greater than an external diameter of a transmission shaft of a matched isolating switch, the lock pin is locked by the coded lock after being inserted into the longitudinal pinhole of the lock body; when a power supply of the eight-combined switch needs to be stopped, a professional serviceman disconnects the eight-combined switch, then inserts the isolating switch safety lock used for the coal mining working face into a lower side of a flange end of the correlated switch, and enables the transmission shaft of the isolating switch to pass through the vertical through hole on the lock body, then inserts the lock pin, and finally uses the coded lock to fix the lock body and the lock pin together. The isolating switch safety lock of the utility model has the advantages of simple structure and convenient use, and is used in combination with the matched isolating switch, thus the isolating switch safety lock is suitable for being used by various coal mines.
Description
Technical field
The utility model relates to a kind of coal-face isolating switch safety lock.
Background technology
1674 work planes are the first thin coal bed fully-mechanized mining face of Beisu mine, eight stacked switches of when coordinative composition of equipments, having selected Tianjin Huaning company to produce, this switching manipulation is simple, easy to use, anyone can both operate, have many gears pooling feature, its handle arrangement can, the said firm patent documentation CN201237996Y disclosed referring on May 13rd, 2009.
In order to ensure " who have a power failure, who send electricity " system, avoid maloperation to occur, need to design and produce a cover blocking device for eight stacked switches, accomplish really who has a power failure must whom send electricity, the such device of shortage in the prior art.
The utility model content
The technical problems to be solved in the utility model is the defects that how to overcome prior art, and a kind of coal-face isolating switch safety lock is provided.
For solving the problems of the technologies described above, this coal-face comprises lock body, lock pin and coded lock with the isolating switch safety lock, wherein the lock body main body is prolate side's bodily form, have vertical pin-and-hole and vertical through hole on it, the two intersect vertical axis, wherein vertically the through hole internal diameter is greater than the power transmission shaft external diameter of adapted isolating switch, and lock pin is locked by coded lock after inserting vertical pin-and-hole of lock body.So design, when situations such as running into maintenance, maintenance, maintenance need to be stopped eight combined switch electric powers, the specialized maintenance personnel disconnect eight stacked switches, then this coal-face is inserted the flange end below of related switch with the isolating switch safety lock, and the power transmission shaft that makes isolating switch passes the vertical through hole on the lock body, then, plug lock pin, with coded lock lock body and lock pin being fixed together at last gets final product.
As optimization, described coded lock is padlock, and the lock pin end is provided with tailgate, be equipped with flat board on the relevant position of lock body, all have the padlock hole on tailgate and the flat board, after lock pin inserts vertical pin-and-hole of lock body, the padlock hole of tailgate and flat board is overlapping, and coded lock just is locked in the padlock hole.So design is simple in structure.
As optimization, the padlock hole on tailgate and the flat board is three.So design can be gone up three coded locks simultaneously, and all the coded lock handle of all opening the locking of just can closing send electricity.
The utility model coal-face has advantage simple in structure, easy to use with the isolating switch safety lock, be used in combination with supporting keeping apart, can guarantee that " whose power failure; who send electricity " system is effectively implemented, avoid occuring maloperation, be the desirable corollary apparatus of eight stacked switches that existing isolating switch, particularly Tianjin Huaning company produce, be fit to various collieries and use.
Description of drawings
Below in conjunction with accompanying drawing this coal-face is described further with the isolating switch safety lock:
Fig. 1 is the locking states structural representation that this coal-face is used the isolating switch safety lock;
Fig. 2 is the decomposition texture schematic diagram that this coal-face is used the isolating switch safety lock.
Among the figure: 1 is that lock body, 2 is that lock pin, 3 is that coded lock, 4 is that vertical pin-and-hole, 5 is that vertical through hole, tailgate, 7 are that flat board, 8 is the padlock hole.
The specific embodiment
Embodiment one: as shown in Figure 1, 2, this coal-face comprises lock body 1, lock pin 2 and coded lock 3 with the isolating switch safety lock, wherein lock body 1 main body is prolate side's bodily form, have vertical pin-and-hole 4 and vertical through hole 5 on it, the two intersect vertical axis, wherein vertically through hole 5 internal diameters, are locked by coded lock 3 after lock pin 2 inserts vertical pin-and-hole 5 of lock body greater than the power transmission shaft external diameter of adapted isolating switch.
Described coded lock 3 is padlock, and lock pin 2 ends are provided with tailgate 6, is equipped with dull and stereotyped 7 on the relevant position of lock body, all have padlock hole 8 on the tailgate 6 and dull and stereotyped 7, after lock pin 2 inserted vertical pin-and-hole 5 of lock body 1, the padlock hole 8 on the tailgate 6 and dull and stereotyped 7 was overlapping, and coded lock 3 just is locked in the padlock hole 8.Padlock hole 8 on the tailgate 6 and dull and stereotyped 7 is three.
Claims (3)
1. coal-face isolating switch safety lock, it is characterized in that: comprise lock body, lock pin and coded lock, wherein the lock body main body is prolate side's bodily form, have vertical pin-and-hole and vertical through hole on it, the two intersect vertical axis, wherein vertically the through hole internal diameter is greater than the power transmission shaft external diameter of adapted isolating switch, and lock pin is locked by coded lock after inserting vertical pin-and-hole of lock body.
2. coal-face as claimed in claim 1 isolating switch safety lock, it is characterized in that: described coded lock is padlock, the lock pin end is provided with tailgate, be equipped with flat board on the relevant position of lock body, all have the padlock hole on tailgate and the flat board, after lock pin inserted vertical pin-and-hole of lock body, the padlock hole of tailgate and flat board was overlapping, and coded lock just is locked in the padlock hole.
