Abstract
The utility model provides a mining feeder switch safety blocking device which comprises a locking plate installed on a locking rod fixing frame, wherein the lower end of the locking rod fixing frame is provided with a lock sleeve, one end of the lock sleeve is connected with the locking plate through a padlock, and the other end of the lock sleeve is abutted against a switch power out and on handlebar. The mining feeder switch safety blocking device uses the lock sleeve, the locking plate and the padlock to belock a feeder switch, and is simple in structure and convenient to use. Before the operation of switching on the feeder switch is carried out, the padlock needs opening, the problem that operating personnel carries out erroneously power transmission due to carelessness is solved, power failure and transmission principles of who lock, who list, who delist, who unlock and who power transmission are achieved, and using effect is good.
Description
Technical field
The utility model belongs to special equipment field under the coal mine, is specifically related to a kind of underground mine use feeding switch and prevents the electric external safety interlock system of misdelivering.
Background technology
The electric flame-proof type switch in colliery mainly uses each operating area in the down-hole, the startup of each consumer of major control, stops, and makes things convenient for the operation of various device.This kind explosion-proof feeding switch also can be used ground coal preparation plant, well head machine room and mine explosion-proof field.
In normal productive process, because rhythm of production is nervous, flameproof feed switch institute on-load electric fixtures breaks down and needs maintenance or move when setting grade equipment cable, the operating personnel is sometimes because careless and inadvertent console switch stops sending the electric hand handle, cause the misdelivery electricity, cause electric shock accidents, the deadlock lever in the deadlock lever fixed mount revolves not in place sometimes, can't split to close down and send electric hand playing position-limiting action, also easily cause the danger of electric shock accidents.
Summary of the invention
The purpose of this utility model is to provide a kind of mining feed switch safety interlock system.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise the locking plate that is arranged on the deadlock lever fixed mount, the lower end of described deadlock lever fixed mount is provided with lock tube, and an end of lock tube links to each other with locking plate by padlock, and the other end withstands on switch and stops sending electric hand upper.
Offer strip hole on the described lock tube, lock tube is enclosed within on the locking plate by strip hole, offers on the locking plate for the hole that connects padlock.
Described locking plate is T-shaped.
Described lock tube is L-type.
Mining feed switch safety interlock system described in the utility model utilizes lock tube, locking plate and padlock with the feeding switch locking, simple in structure, easy to use, before feeding switch carried out closing operation, need to open padlock, solved the operating personnel because the problem of careless and inadvertent misdelivery electricity, realized " who has a power failure, who locks, who lists, who is delisted, who unblanks, who send electricity " stop send electric principle, result of use is good.
Description of drawings
Fig. 1 is result of use figure of the present utility model;
Fig. 2 is the structural representation of locking plate described in the utility model, and wherein, Fig. 2 (a) is top view, and Fig. 2 (b) is lateral view;
Fig. 3 is the structural representation of lock tube described in the utility model, and wherein, Fig. 3 (a) is top view, and Fig. 3 (b) is lateral view;
Among the figure: locking plate 1, deadlock lever fixed mount 2, lock tube 3, switch stop sending electric hand 4, padlock 5.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises the locking plate 1 that is arranged on the deadlock lever fixed mount 2, the lower end of described deadlock lever fixed mount 2 is provided with lock tube 3, one end of lock tube 3 links to each other with locking plate 1 by padlock 5, and the other end withstands on switch and stops sending electric hand on 4, offers strip hole on the described lock tube 3, lock tube is enclosed within on the locking plate 1 by strip hole, offer on the locking plate 1 for the hole that connects padlock 5, described locking plate 1 is T-shaped, and described lock tube 3 is L-type.
During maintenance, stop sending electric hand getting to gate-dividing state on switch, T-shaped locking plate is inserted the deadlock lever fixed mount, put the L-type lock tube in T-shaped locking plate bottom, locking in the hole after passing the strip hole of T-shaped locking plate from the L-type lock tube on T-shaped locking plate gets final product.
Embodiment
Be exclusively used in (the XXX--200A (400A)/1140(660) of explosion-proof feeding switch under the coal mine
Type) external blocking device is comprised of T-shaped locking plate, L-type lock tube, common padlock three parts.
This external blocking device is to utilize switch to stop sending electric hand the usefull space at power failure position and deadlock lever fixed mount, with thick steel plate design processing one cover external mechanical latching, i.e. T-shaped locking plate and the L-type lock tube of 6mm.When the operating personnel needs operation switch stopped sending electric hand beating to the position that has a power failure, vertically insert in the deadlock lever fixed mount with T-shaped locking plate, put again the L-type lock tube, utilize on the L-type lock tube bight portion to withstand switch and stop sending the electric hand handle, put at last common padlock pinning and get final product.
The utility model beneficial effect and technical characterictic:
1, draw materials conveniently, process simple.
2, light and flexible, easy to carry.
3, simple to operate, practical, safety factor is high.
4, more safe and reliable realization " who has a power failure, who locks, who lists, who is delisted, who unblanks, who send electricity " stop send electric principle, avoided the danger of misdelivery electricity, obtained good effect.
