Abstract
The utility model relates to a stepless rope winch, in particular to a novel overwinding protection switch of the stepless rope winch. The novel overwinding protection switch solves the problems that an existing overwinidng protection switch is too close to a rail and is prone to being damaged, and a mechanical toggle switch is not flexible in triggering. The novel overwinding protection switch of the stepless rope winch comprises a protective switch body, a base of the protective switch body is fixedly connected with a U-bar, one end of the U-bar is vertically and fixedly connected with the rail, the U-bar is connected with a steel rib which is rotatable and parallel with the U-bar, the end, close to the protective switch body, of the steel rib is provided with flat iron I in a welded mode, the flat iron I is connected with a mechanical switch of the protective switch body through an iron wire, the end, close to the rail, of the steel rib is provided with flat iron II, and the top of the flat iron II is arc-shaped and higher than the upper surface of the rail. Compared with the prior art, the distance from the novel overwinding protection switch to the rail is proper, a device capable of automatically control the mechanical switch is arranged, and therefore the problems that the overwinidng protection switch is too close to the rail and is prone to being damaged, and the mechanical toggle switch is not flexible are solved.
Description
Technical field
The utility model relates to endless rope winch, specifically a kind of new endless rope winch overtravel protection switch.
Background technology
The auxiliary conveying equipments of using under mine at present is mainly endless rope winch.Along with the lifting of mine capacity, transportation volume is also along with continuous increase.The overtravel protection switch that endless rope winch is used is KHGJ0.5/24 mining intrinsic safety type pulleying switch.This switch is comprised of two switches, and one is the infrared probe switch, and one is mechanical toggle switch.These two switch in parallel realize the overtravel protection to continuous rope.
This overtravel protection switch existing problems:
1) the overtravel protection switch leaves the right or normal track too closely, in transportation, is easy to be broken;
2) mechanical toggle switch touches dumb.
Summary of the invention
The utility model leaves the right or normal track and is too closely easily broken in order to solve existing overtravel protection switch, and mechanical toggle switch touches inflexible problem, and a kind of new endless rope winch overtravel protection switch is provided.
In order to address the above problem; the utility model is taked following technical scheme: a kind of new endless rope winch overtravel protection switch; comprise protection switch; the protection switch base is fixedly connected with channel-section steel; one end of channel-section steel is fixedly connected with track is vertical; be connected with rotatable on channel-section steel and be parallel to the reinforcing bar of channel-section steel; reinforcing bar is welded with band iron I near protection switch one end; band iron I is connected with the mechanical switch of protection switch by iron wire; reinforcing bar is welded with band iron II near track one end, and band iron II top is circular-arc and higher than the upper surface of track.
The base of protection switch is more than or equal to 900mm apart from the outer rim of track.Make keeping the distance of protection switch and track.
The junction of reinforcing bar and band iron I is provided with spring.Spring, for pulling band iron, facilitates mechanical switch to reset.
Be welded with limiting device between channel-section steel and band iron II.Prevent that band iron II from being damaged by pressure.
Compared with the prior art, the utility model and orbital distance are moderate, and are provided with the device of robot brain tool switch, thereby solved the overtravel protection switch, leave the right or normal track and are too closely easily broken, and mechanical toggle switch touches inflexible problem.
The accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the protection switch schematic diagram;
Fig. 3 is the utility model left view;
1-band iron II in figure, 2-track, 3-channel-section steel, 4-reinforcing bar, 5-protection switch, 6-mechanical switch, 7-band iron I.
The specific embodiment
As shown in Figure 1; a kind of new endless rope winch overtravel protection switch; comprise protection switch 5; protection switch 5 bases are fixedly connected with channel-section steel 3; one end of channel-section steel 3 is fixedly connected with track 2 is vertical; be connected with rotatable on channel-section steel 3 and be parallel to the reinforcing bar 4 of channel-section steel 3; reinforcing bar 4 is welded with band iron I7 near protection switch 5 one ends; band iron I7 is connected (mechanical switch is shown in Fig. 2) by iron wire with the mechanical switch 6 of protection switch 5; reinforcing bar 4 is welded with band iron II1 near track 2 one ends, and band iron II1 top is circular-arc and higher than the upper surface (see figure 3) of track 2.
The base of protection switch 5 is more than or equal to 900mm apart from the outer rim of track.
Reinforcing bar 4 is provided with spring with the junction of band iron I7.
Be welded with limiting device between channel-section steel 3 and band iron II1.
When endless rope winch process band iron II1, band iron II1 is depressed, thereby makes band iron I also be depressed the driving mechanical switch opens by reinforcing bar 4.After endless rope winch leaves band iron II1, spring automatically resets band iron I7, thereby drive band iron II1, resets.
Claims (4)
