Abstract
The utility model relates to the field for mining equipment, particularly to an interlocking device of pneumatic curved rail and pneumatic railroad switch of endless rope winch, which solves the problem of the current endless rope winch that the pneumatic curved rail and the pneumatic railroad switch are easy to cause manual misoperation so as to drive the endless rope winch to collide without the possibility of passing through, which finally squeezes the steel rope to be broken, and comprises a railroad switch air cylinder connected with the railroad switch and arranged between the two sleepers and a curved rail air cylinder connected with the curved rail and arranged between two sleepers, and the device also comprises a three-position four-way valve, the two input ends of the three-position four-way valve are connected with an air pipe and a hydraulic oil pipe, wherein one output end is connected with the air inlet of the railroad switch air cylinder through a pipeline AB, the other output end is connected with the air inlet of the curved rail air cylinder through a pipeline CD, the air outlet of the railroad switch air cylinder is communicated with the pipeline CD through a pipeline EF, and the air outlet of the curved rail air cylinder is communicated with the pipeline AB through a pipeline GH. The utility model has the advantages of simple structure, easy operation, low cost and excellent effect as proved through practice.
Description
Technical field
The utility model relates to the mining equipment field, is specially pneumatic bend of a kind of endless rope winch and pneumatic track switch interlock system.
Background technology
At present, pneumatic track switch and pneumatic bend be not before interlocking, pneumatic track switch and pneumatic bend are the mechanisms that two three-position four-way valves drive two cover independent operatings of two cylinder operations, in actual use, when straight way transports, at first to pull pneumatic track switch, pull pneumatic bend again, bend and bend are disconnected, purpose be convenient to endless rope winch meet and discuss by, realize transporting safely.When vehicle when bend runs to straight way and is convenient to use endless rope winch, pull pneumatic track switch once more and pull pneumatic bend again, bend is formed path, could realize transporting safely with endless rope winch.But, when workman's practical operation often when bend transportation makes the transportation of endless rope winch straight way into, pull pneumatic track switch and forgotten to pull pneumatic bend, like this when endless rope winch is met and discussed by bend, thus since bend be closed can't be with regard to causing endless rope winch to meet and discuss by squeezing off steel rope.
Summary of the invention
The utility model does not have interlock system in order to solve existing pneumatic track switch of endless rope winch and pneumatic bend, easily cause artificial incorrect operation and cause endless rope winch to be met and discussed and to provide pneumatic bend of a kind of endless rope winch and pneumatic track switch interlock system by squeezing off the problem of steel rope.
The utility model is to adopt following technical scheme to realize: pneumatic bend of endless rope winch and pneumatic track switch interlock system, comprise with track switch and being connected, and the track switch cylinder between two sleepers and be connected with bend, and the bend cylinder between two sleepers, innovative point of the present utility model is also to comprise a three-position four-way valve, two input ends of three-position four-way valve respectively with airduct, hydraulic oil pipe connects, one of them mouth is connected with the admission port of track switch cylinder by pipeline AB, another mouth is connected with the admission port of bend cylinder by pipeline CD, the air extractor duct of track switch cylinder EF by the road is communicated with pipeline CD, and the air extractor duct of bend cylinder GH by the road is communicated with pipeline AB.Described three-position four-way valve is existing known products, and its structure and principle of work are that those of ordinary skill in the art is known.
Adopt structure design of the present utility model, move simultaneously by a three-position four-way valve switch with follow up movement cylinder and bend cylinder, constitute a cover operating unit, be different from original two cover independent operating mechanisms, when pulling pneumatic track switch, pneumatic bend moves simultaneously, effectively prevent to squeeze off the phenomenon of endless rope winch steel rope because of artificial incorrect operation, and simple in structure, easy and simple to handle, cost is lower, through facts have proved, result of use is very good, is applicable to any place that needs installation of endless rope winch under the coal mine.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-track switch; The 2-sleeper; 3-track switch cylinder; The 4-bend; 5-bend cylinder; The 6-three-position four-way valve; The 7-airduct; 8-track switch cylinder admission port; 9-bend cylinder admission port; 10-track switch cylinder air extractor duct; 11-bend cylinder air extractor duct; The 12-steel rope; The 13-cylinder.
The specific embodiment
Pneumatic bend of endless rope winch and pneumatic track switch interlock system, as shown in Figure 1, comprise with track switch 1 and being connected, and the track switch cylinder 3 between two sleepers 2 and be connected with bend 4, and the bend cylinder 5 between two sleepers 2, it is characterized in that also comprising a three-position four-way valve 6, two input ends of three-position four-way valve 6 respectively with airduct 7, hydraulic oil pipe connects, one of them mouth is connected with track switch cylinder admission port 8 by pipeline AB, another mouth is connected with bend cylinder admission port 9 by pipeline CD, track switch cylinder air extractor duct 10 EF by the road is communicated with pipeline CD, and bend cylinder air extractor duct 11 GH by the road is communicated with pipeline AB.
In actual use, no matter be to be used for the straight way transportation, bend and bend are disconnected or be used for the bend transportation, bend and bend are formed path, only need to handle the action that three-position four-way valve can be realized two cylinders synchronously, make two cylinders alternately be in different station (or push away or draw).Below being to be in the station that pushes away with the track switch cylinder, is that example illustrates the whole system operation process and the bend cylinder is in the station that draws:
High-pressure blast successively by the road AB, track switch cylinder admission port enter in the track switch cylinder, promote piston, piston rod travels forward, and moves thereby promote track switch, high-pressure blast is back to three-position four-way valve through track switch cylinder air extractor duct, pipeline EF, pipeline CD again, recycles; Meanwhile, GH, bend cylinder air extractor duct enter in the bend cylinder high-pressure blast by the road successively, promotion piston, piston rod move backward, thereby promoting bend moves, moving direction is opposite with the track switch moving direction, high-pressure blast is back to three-position four-way valve through bend cylinder admission port, pipeline CD again, recycles.
