Description
Technical field
The utility model relates to a kind of self-locking track switch of surging that is applicable to railway under coal mine, belongs to equipment technology field of transport.
Background technology
At present, the railroad turnout that China's coal-mine down-hole is used has multiple, each has something to recommend him on properity, according to the mode of pulling of track switch, can be divided into manual, electronic and Pneumatic rail switch.The arranged outside of hand-operated points has a rocking arm, and on rocking arm, operated by rotary motion has weight, the operation that has coordinated track switch of inertia with manpower by weight drop.The shortcoming of this track switch is that operation easier is larger, and the physical qualification of operating personal, operation skill and skill level are had relatively high expectations, and workman's labour intensity is larger.Electronic and Pneumatic rail switch can be handled on control desk, its responsiveness is very fast, contributes to improve railway transportation efficiency, but due to narrow space under coal mine and track switch quantity more, central control system is installed unactual, and needs the cost of input higher.
In a word, the track switch that under existing coal mine, railway is used is all undesirable, is necessary to design a kind of novel track switch that is applicable to railway under coal mine.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of and takes up room littlely, and laid down cost is low, self-locking track switch under easy to operate, safe coal mine.
Problem described in the utility model realizes with following technical proposals:
Self-locking track switch under a kind of coal mine, formation comprises track switch, hydraulic actuating cylinder and hand-operated three-position, described hydraulic actuating cylinder is fixed on track switch one side, its piston rod is connected with track switch, the P mouth of described hand-operated three-position connects static pressure water coolant inlet pipe, T mouth connects static pressure water return water pipe, and its A mouth and B mouth connect respectively two static pressure water interfaces at hydraulic actuating cylinder two ends.
Self-locking track switch under above-mentioned coal mine, is provided with shutoff valve on the static pressure water coolant inlet pipe being connected at the P mouth with hand-operated three-position.
Self-locking track switch under above-mentioned coal mine is provided with filter between the P of hand-operated three-position mouth and shutoff valve.
Self-locking track switch under above-mentioned coal mine is provided with compression indicator between shutoff valve and filter.
Self-locking track switch under above-mentioned coal mine, described hydraulic actuating cylinder is two-way hydraulic cylinder, the stroke of its piston rod is 150mm.
The utility model is usingd down-hole static pressure water as propulsion source, by hand-operated three-position, control the action of track switch, not only simple in structure, easy to operate, safety, and do not need to drop into power plant, there is the advantages such as little, the economical and efficient of taking up room, be particularly suitable for using in underground transportation system.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, each label is: 1, track switch, 2, shutoff valve, 3, compression indicator, 4, filter, 5, hand-operated three-position, 6, hydraulic actuating cylinder, I, water inlet, O, water outlet.
The specific embodiment
Referring to Fig. 1, the utility model comprises track switch 1, shutoff valve 2, compression indicator 3, filter 4, hand-operated three-position 5 and hydraulic actuating cylinder 6.In Fig. 1, I is the water inlet of static pressure water, and the pressure of static pressure water is 4.5MPa left and right, as propulsion source.Each in figure section water pipe all adopts the high-pressure rubber pipe of Ф 10mm15MPa; Structure and the weighted points of track switch 1 are basic identical, are exactly weight and weight armed lever are removed, and the intermediate rod of track switch is connected by chuck bearing pin with hydraulic actuating cylinder 6, realize linkage function; Shutoff valve 2 is for controlling being connected of hydraulic tubing and static pressure water, and the installation of shutoff valve 2 makes the replacing of parts convenient; Compression indicator 3 is arranged on hydraulic tubing by threeway, and normally whether, the range of compression indicator 3 is 0-15MPa for its effect is convenient operation person observes pressure; Filter 4, for the impurity of static pressure water is filtered, prevents that hand-operated three-position 5 from stopping up; Hand-operated three-position 5 is for controlling hydraulic actuating cylinder 6, select the benefit of hand valve to have three: the first, with hand valve, replace electric-control system and control, be conducive to reduce costs, second, easy to operate, only need pull gently hand change over valve gets final product complete operation, the 3rd, three position four-way directional control valve is to control the flexible of hydraulic actuating cylinder by the sway of spool, realize deciliter action of track switch, when valve body turns back midway location (being zero-bit), can realize the self-locking of hydraulic actuating cylinder; It is the two-way hydraulic cylinder of Ф 90 * 150 that hydraulic actuating cylinder 6 is selected specification, and its forced stroke is 150mm, has met the required distance of switch travel.O is water outlet, i.e. the reclaim line of hydraulic pressure water outlet.
Operating mode of the present utility model is as follows:
Headstock stops before track switch, run rider gets off, and confirms whether shutoff valve 2 is opened, if do not opened, the position that shutoff valve is forwarded to open, the pointer of confirmation compression indicator 3, behind 4.5MPa left and right, is controlled the action of hydraulic actuating cylinder 6 by hand-operated three-position 5, the piston rod of hydraulic actuating cylinder 6 drives track switch 1 to move, after track switch operation puts in place, operating personal is pulled middle zero-bit by hand-operated three-position 5, realizes locking, completes single job.
Feature of the present utility model is:
This self-locking track switch of surging adopts down-hole static pressure water as propulsion source, and large lane, down-hole is all furnished with static pressure water, can gather materials on the spot, and has reduced the input of power plant; Operating personal is hidden little cave and is pulled weight without entering, and easy to operate, safety has solved the manual problem that track switch labour intensity is large of pulling; Hand-operated three-position 5 has auto-lock function, can effectively prevent from rebounding after track switch from putting in place, causes mine car falling rut.
