Abstract
The utility model discloses a support self-moving device without a repeated supporting unit, wherein a first walking support arm is hinged on a support base, and the front end of the first walking support arm is hinged with a second walking support arm; a first pulling and moving jack is arranged between the support base and the first walking support arm, and a second pulling and moving jack is arranged between the first walking support arm and the second walking support arm. The front end of the second walking support arm is bent downwards. The first pulling and moving jack and the second pulling and moving jack are respectively provided with an operating valve. The two groups of pulling jacks are controlled by the control valve, and the walking support arm is extended forwards, swung downwards and pulled back, so that the self-moving function of the unit support is realized.
Description
Technical Field
The utility model relates to a hydraulic support is strutted to colliery working face crossheading especially relates to a support of no support unit is from moving device repeatedly.
Background
The research of working face crossheading support technology and equipment has been developed greatly in recent years, and various types of forepoling supports are successfully developed by a plurality of production and research units and are applied, so that the forepoling of about 20 meters is realized on a plurality of modern mine working faces. The large advance supports all adopt a queuing type gradually-advancing support moving mode, so that the roof is inevitably repeatedly supported, the damage to the roof is easily caused, and the maintenance is difficult, therefore, the advance support hydraulic supports can not be completely adopted in a gateway mining stress influence area (usually about 50 meters), only backward support modes such as a multi-row single hydraulic support and shed beam mode can be adopted beyond 20 meters of the advance support, the efficiency is low, and the safety of pedestrians and operators in a roadway is difficult to completely guarantee.
In the prior art, the existing moving frame mode of a unit bracket is as follows:
1) a monorail crane is arranged on the top plate of the crossheading, and the rear frame can move forwards through the monorail crane.
2) The bracket is pulled to move forwards through a winch.
3) Through the support carrier, realize the removal mode that the after-poppet becomes the fore-stock.
At present, in a small-working-resistance light unit bracket of a small coal mine, a bracket moving mode of changing a rear bracket into a front bracket is realized through a suspension sliding mode, but the mode is only suitable for the small-working-resistance light unit bracket, and a large bracket needs to be researched and searched for a completely different bracket moving mode.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a there is not support unit support from moving device repeatedly.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a support self-moving device without a repeated supporting unit, wherein a first walking support arm is hinged on a support base, and the front end of the first walking support arm is hinged with a second walking support arm;
a first pulling and moving jack is arranged between the support base and the first walking support arm, and a second pulling and moving jack is arranged between the first walking support arm and the second walking support arm.
By the above-mentioned the technical scheme provided by the utility model, the embodiment of the utility model provides a no support unit support that relapse moves device certainly pulls through two sets of jacks that move, with walking support arm protraction-lower hem-pullback, realizes the function of moving certainly of unit support.

Fig. 2a, fig. 2b, and fig. 2c are flow charts of the self-moving type support frame moving without the repeated supporting unit according to the embodiment of the present invention.
In the figure:
1. the device comprises a first walking support arm, a second walking support arm, a first pulling and moving jack, a second pulling and moving jack and a first walking support arm, wherein the first walking support arm 2 is connected with the second walking support arm, the second walking support arm 3 is connected with the first pulling and moving jack, and the second pulling and moving jack is connected with the second walking support.
Detailed Description
Embodiments of the present invention will be described in further detail below. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
The utility model discloses a no support unit support from moving device relapses, the concrete implementation mode of its preferred is:
a first walking support arm is hinged to the support base, and a second walking support arm is hinged to the front end of the first walking support arm;
a first pulling and moving jack is arranged between the support base and the first walking support arm, and a second pulling and moving jack is arranged between the first walking support arm and the second walking support arm.
The front end of the second walking support arm is bent downwards.
And the first pulling and moving jack and the second pulling and moving jack are respectively provided with an operating valve.
The utility model discloses a there is not support element support from moving device repeatedly, through to complicated geological conditions, have the investigation and the mechanism research of the circumstances such as strike mine pressure, broken roof, soft bottom plate, through to strutting equipment, moving a mode, moving research, experiment of a equipment etc. realize continuous no support element support equipment repeatedly's from moving the function.
The specific embodiment is as follows:
as shown in FIG. 1, the self-moving type non-repetitive supporting unit bracket of the present invention is provided with two sets of pulling and moving jacks and bracket walking support arms on the bracket base, and controls the two sets of pulling and moving jacks through the control valve to pull the walking support arms forward, swing down and pull back, thereby realizing the self-moving function of the unit bracket.
The utility model discloses the hinge point of accessible adjustment jack stroke, walking support arm length and relevant connected key element to the speed requirement that moves of unit support is required down to adapt to different work condition, in order to satisfy the support normal use requirement.
As shown in fig. 2a, 2b and 2c, it is a flow chart of the self-moving type support moving without repeated supporting unit.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
