Abstract
The invention discloses an upright hydraulic system with an auxiliary liquid supply pipeline. A hydraulic pipeline educed from a multipass block is connected with the upright of a hydraulic support through a pilot valve and an upright one-way lock in sequence, the auxiliary liquid supply pipeline with a PTO multipass block is connected with the hydraulic pipeline, and the PTO multipass block is arranged at the external of the hydraulic support. Accordingly, it is guaranteed that lifting movement of the hydraulic support can be conducted in a convenient and safe mode under the condition of transportation, that is, under the lowest position.
Description
Technical field
The present invention relates to a kind of hydraulic system of coal-mine hydraulic support, particularly relate to a kind of column hydraulic system with auxiliary liquid feeding pipeline.
Background technology
Along with exploitation coal resources being had to planning, the hydraulic support being applicable to various coal seam occurs like the mushrooms after rain, and is able to rapid popularization.Hydraulic support for low coal seam, as the term suggests, be the support apparatus of mine research and development thinner for coal seam specially.The minimum altitude of current Bracket in Thin Coal Seam is only 0.5 meter, therefore when hydraulic support is in minimum state, consider the demand reason of supporting structure and actual client, maybe cannot connect main feed liquor, lead back liquid high-pressure rubber pipe, or because of the hidden descending operation that cannot carry out support in position of operating valve, descending operation cannot be carried out under causing support under minimum state or operation very difficult or abnormally dangerous (causing wound, residual, the accident such as to die).
As shown in Figure 1, the feed flow form of hydraulic support for low coal seam of the prior art is not with the how logical block of PTO, can only by realizing the operation of operating valve at the descending operation of extreme lower position to support.As shown in Figure 2, if support minimum altitude is very low, cause support cannot rise under travel position at all frame or crane operation very difficult.
Support in working order under, cannot operate support at all, have a strong impact on operating efficiency, even have Personal Risk.
Summary of the invention
The object of this invention is to provide and a kind ofly can ensure that support carries out conveniently under extreme lower position, the column hydraulic system of liquid feeding pipeline assisted by the band of the crane action of safety.
The object of the invention is to be achieved through the following technical solutions:
The column hydraulic system of liquid feeding pipeline assisted by band of the present invention, the fluid pressure line of drawing from many logical blocks is connected with the column of hydraulic support by control valve, column individual event lock successively, described fluid pressure line is connected with auxiliary liquid feeding pipeline, and the outside of described hydraulic support is located at by the control device of described auxiliary liquid feeding pipeline.
As seen from the above technical solution provided by the invention, the column hydraulic system of liquid feeding pipeline assisted by the band that the embodiment of the present invention provides, fluid pressure line due to column is connected with auxiliary liquid feeding pipeline, the outside of hydraulic support is located at by the control device of auxiliary liquid feeding pipeline, can ensure that support is under travel position, the crane action of convenience, safety namely under extreme lower position, can be carried out.
Accompanying drawing explanation
Fig. 1 is the structural representation of column hydraulic system of the prior art;
Fig. 2 is the structural representation of hydraulic support in travel position (extreme lower position);

In figure:
The how logical block of 1-, the how logical block of 2-PTO, 3-pipeline fittings, 4-operating valve, 5-column one-way lock, 6-column.
Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
The column hydraulic system of liquid feeding pipeline assisted by band of the present invention, its preferably detailed description of the invention be:
The fluid pressure line of drawing from many logical blocks is connected with the column of hydraulic support by control valve, column individual event lock successively, and described fluid pressure line is connected with auxiliary liquid feeding pipeline, and the outside of described hydraulic support is located at by the control device of described auxiliary liquid feeding pipeline.
The control device of described auxiliary liquid feeding pipeline is the how logical block of PTO.
Described fluid pressure line comprises main water influent pipeline and main liquid back pipe road.
Described auxiliary liquid feeding pipeline is connected with described many logical fluid pressure lines between block with control valve.
Described auxiliary liquid feeding pipeline and described control valve lock with column individual event between fluid pressure line be connected.
The column hydraulic system of liquid feeding pipeline assisted by band of the present invention, adopt PTO how logical block, be mainly to solve and cannot connect main feed liquor master after support drops to travel position and return sol pipe or affect because operating valve position relationship cannot operate operating valve the problem that support rises frame.By the how logical block of PTO, can ensure that support is under travel position, the crane action of convenience, safety namely under extreme lower position, can be carried out.Increase work efficiency, be also the embodiment of hommization simultaneously.
Specific embodiment one:
As shown in Figure 3, convenient and safe operation can be carried out to operating valve but main feed liquor master cannot be connected return sol pipe;
Specific embodiment two:
As shown in Figure 4, be another kind of form, it mainly solves and cannot operate operating valve and a kind of form designed.
Increase PTO how logical block in bracket hydraulic pipe-line system loop, the how logical block of PTO is placed on stent outer, ensure support under travel position the how logical block of PTO in effective opereating specification.By giving the how logical block feed flow of PTO, accompanying drawing 1 and accompanying drawing 2 two kinds of forms can carry out support descending operation to support under minimum state.This scheme effectively can solve support and cannot connect main feed liquor master return sol pipe and maybe cannot operate operating valve and affect the problem that support rises frame under travel position.
The beneficial effect that technical solution of the present invention is brought:
The how logical block of PTO mainly solves support cannot connect main feed liquor, lead back sol pipe problem and cannot operate operating valve and affect the problem that support rises frame under travel position (i.e. support minimum state).Can be widely used in all kinds of Bracket in Thin Coal Seam, not limit by support height, can say, no matter design how low hydraulic support, as long as need, this kind of feed flow form can be applied, this kind of innovative design of feed flow genomorph.And the minimum altitude restriction of Bracket in Thin Coal Seam, cause the crane problem of support when minimum altitude be design in a difficult problem, this kind of feed flow form that so my company designs goes out cannot carry out the support of crane operation under minimum altitude state for those, can be described as timely.Therefore, there is wide market prospects and economic benefit.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
