Abstract
The present invention relates to hydraulic prop technical field, disclose a kind of hydraulic prop with top support, including top cover, live post, described live post is set in outer shell, is provided with handle body at the top of described outer shell, described handle body is provided with triple-use valve, described top cover upper end is provided with criss-cross support, and described support is telescopic rod.The present invention has installed criss-cross support additional in the There of individual prop, during use criss-cross support expansion can play a part of face support, can preferably be acted on for machine road empty situations such as pushing up；Hydraulic prop can also be supported at the support of expansion in addition, multiple pillars can be with collective effect, more securely and reliably.
Description
Technical field
The present invention relates to hydraulic prop technical field, more particularly to a kind of hydraulic prop with top support.
Background technology
At present, the positive modernization maximization direction of China's coal-mine mining machinery is developed, and super high seam is once adopted complete large-scale
Hydraulic support is come out one after another and come into operation, the matched high working face hydraulic prop demand for termination gib
It is significantly increased.Current hydraulic prop is acted on a little, and support can not be effectively played when running into when machine road is empty to be pushed up
Effect, many individual prop collective effects are generally required, the congestion in space can be also caused while adding cost, influences work
Make the current of personnel.
The content of the invention
The shortcomings that present invention is for hydraulic prop supporting power weakness in the prior art, there is provided one kind carries top support
Hydraulic prop.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
A kind of hydraulic prop with top support, including top cover, live post, described live post is set in outer shell, described
Outer shell bottom is provided with handle body, and described handle body is provided with triple-use valve, and described top cover upper end is provided with criss-cross support, institute
The support stated is telescopic rod.
Preferably, described outer shell bottom is additionally provided with long joining section and base.
Preferably, the length of described cross bracket is 0.4m when not deployed, it is 0.8m after expansion.
The present invention has significant technique effect as a result of above technical scheme：In the There of individual prop
Installed criss-cross support additional, during use criss-cross support expansion can play a part of face support, for empty top in machine road etc.
Situation can be acted on preferably；Hydraulic prop can also be supported at the support of expansion in addition, multiple pillars can be made jointly
With more securely and reliably.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
The toponym that each number designation is referred in accompanying drawing is as follows：1-live post, 2-outer shell, 3-long joining section, 4-hand
Body, 5-triple-use valve, 6-support, 7-base, 8-top cover.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of hydraulic prop with top support, as illustrated, being arranged including top cover 8, live post 1, described live post 1
In outer shell 2, the described bottom of outer shell 2 is provided with handle body 4, and described handle body 4 is provided with triple-use valve 5, on described top cover 8
End is provided with criss-cross support 6, and described support 6 is telescopic rod；The described bottom of outer shell 2 is additionally provided with long joining section 3 and base
7.The length of described cross bracket 3 is 0.4m when not deployed, is 0.8m after expansion.
After installing hydraulic prop, support 6 is fixed on top cover 8, the situation selection supported as needed extends
The size that bar extends, live post 1, which rises, after fluid injection pushes up support 6 advance opening position.If the local pressure of support is excessive, can
Separately to take the other positions of hydraulic prop supporting support；Multiple pillars support criss-cross support 6 simultaneously, not only support
More firmly, accept also evenly, additionally it is possible to the use number of individual prop is reduced, it is simple and convenient.
In a word, presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent be the foregoing is only
Change and modification, it should all belong to the covering scope of patent of the present invention.
