Abstract
The invention relates to a small-winch overwinding safety device which is used for the field of coal mining conveying, and belongs to a control system. According to the technical scheme, the small-winch overwinding safety device comprises a winch control combined switch, a winch with a front frame rope wheel, a tramcar and a steel wire rope, and further comprises a normally-closed contact connected with a switch terminal of the winch control combined switch in series, a base of the normally-closed contact is additionally arranged on the front frame rope wheel of the winch, a 45-degree included angle is formed between the base and the front frame rope wheel, and the normally-closed contact is located on an unwinding and winding path of the steel wire rope. The small-winch overwinding safety device has the advantages that the stop terminal is remotely controlled by a QBZM switch to be connected with the normally-closed contact in series to form a winch stop control loop, when a winch driver breaks rules to nap and carries out wrong operation, the winding rope of the winch is disordered and the steel wire rope is twisted into a brake strap, the tramcar is in contact with the normally-closed contact, and the winch switch will be immediately powered off to stop running. By means of the small-winch overwinding safety device, the necessary devices are simply and additionally installed on an original device, the safety protection aim is achieved, and cost is low.
Description
Technical field
This patent relates to a kind of puffer overwinding safety gears, for transport field of mining, belongs to a kind of control system.
Background technology
Due to the winch pulleying that the safety hazard (mechanical breakdown) of Unsafe behavior (operation against rules) and thing causes, it is the difficult problem that management transported safely by puffer.Because hoistman energy does not concentrate maloperation, cause the winch rope that breaks to take out people, damage winch, mine car happens occasionally, not only cause economic loss, and the personal safety of serious threat hoistman.
Summary of the invention
The object of this invention is to provide a kind of puffer overwinding safety gears, realize the overtravel protection problem that winch is in operation.
For achieving the above object, the technical solution used in the present invention is:
A kind of puffer overwinding safety gears; comprise winch switchgroup, winch, mine car and steel rope with side arm rope sheave; it is characterized in that; also comprise the normally closed contact of connecting with the switch terminal of winch switchgroup; winch side arm rope sheave adds the base of normally closed contact; described base and side arm rope sheave are 45 degree of angles, and described normally closed contact is positioned at the releasing of steel rope with on recovery path.
According to described puffer overwinding safety gears, it is characterized in that, described winch switchgroup is QBZM type.
The invention has the advantages that, it is sharp that QBZM switch Long-distance Control is stopped terminal series-shunt normally closed contact by us, form winch and stop control loop, when hoistman occur violating the regulations dozing off, maloperation, winch flake down disorderly, steel rope climb into situations such as the strap of the brakes time, mine car contacts normally closed contact, and winch switch will shut down immediately in power-off.This device simply installs necessaries additional on existing equipment, and realize safety guard-safeguard object, cost is low, and benefit and safe effect promote obviously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is electrical wiring schematic diagram of the present invention.
In accompanying drawing: 1, track; 2, mine car; 3, steel rope; 4, normally closed electric shock; 5, side arm rope sheave; 6, winch; 7, winch switchgroup; 8, series connection local circuit; 9, base.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as shown in Figure 1,
A kind of puffer overwinding safety gears; comprise winch switchgroup 7, winch 6, mine car 2 and steel rope 3 with side arm rope sheave 5; it is characterized in that; also comprise the normally closed contact 4 of connecting with the switch terminal of winch switchgroup 7; winch side arm rope sheave 5 adds the base 9 of normally closed contact 4; described base 9 and side arm rope sheave 5 are in 45 degree of angles, and described normally closed contact 4 is positioned at the releasing of steel rope 3 with on recovery path.
According to described puffer overwinding safety gears, it is characterized in that, described winch switchgroup 7 is QBZM type.
QBZM switch Long-distance Control is stopped terminal series-shunt normally closed contact by us, forms winch and stops control loop.6mm steel plate is adopted to make safety basement, be arranged on winch side arm rope sheave by 45 ° of angles, when hoistman occur violating the regulations dozing off, maloperation, winch flake down disorderly, steel rope climb into situations such as the strap of the brakes time, mine car contacts normally closed contact, and winch switch will shut down immediately in power-off.
Through onsite application situation, fundamentally solve the difficult problem that winch pulleying jeopardizes personal security, rapid power-off when having accomplished pulleying, maloperation, mechanical breakdown, reaches the Expected Results of design.Decrease shipping accident rate, thoroughly eradicated these major safety risks of winch pulleying, ensure that Lifting Convey safety, the annual fund input 2.0 ten thousand yuan of saving indirectly.
Embodiment recited above is only be described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; under the prerequisite not departing from design concept of the present invention; the various modification that in this area, common engineering staff make technical scheme of the present invention and improvement, all should fall into protection scope of the present invention.
