Abstract
The invention provides a novel self-moving roadway advance support bracket which is suitable for advance support of two roadways of a coal mining working face in a well. The existing advance support for two roadways of a coal mining working face of a well worker is supported by a single hydraulic prop and an n-shaped steel beam and is carried by manpower, which not only influences the advancing degree of the working face, but also is unsafe. However, each time the two self-moving roadway advance support brackets are pushed for one cycle, the top plate of the whole advance support part is repeatedly supported once, so that the manual damage to the roadway top plate is serious, and the self-moving roadway advance support bracket is not applicable to a roadway with a general top plate which is not particularly hard. The invention provides a self-moving roadway advance support bracket shown in figure 1, which keeps the support space and the support strength formed by the existing support form in the roadway, the forward movement of the self-moving roadway advance support bracket is not like the existing self-moving roadway support bracket, the advance is carried out from the top of the rear frame one frame, but the frame positioned at the tail end is directly moved to the front end through a circulating hanging rail, and simultaneously, the support of the middle frames is kept still, thereby not only achieving the self-moving, but also realizing the ideal working condition that only one time of supporting the top plate is carried out in each self-moving process, and being suitable for various top plate conditions.
Description
The present invention relates to a kind of novel self-moving type lame advanced supporting rack, be applicable to the advance support in well worker coal mining work plane two lanes.
At least 20 meters all need add strong supporting in advance before the well worker coal mining work plane two lane work planes, and existing support form is hydraulic prop and supports the supporting of II section steel beam.Along with the propelling of work plane, need the workman to dismantle hydraulic prop and II section steel beam, and be transported to front supporting again, belong to heavy manual labor, both influenced the propelling degree, dangerous again.Two kinds of lame advanced supporting racks of nearest domestic-developed are though solved the problem of a dead lift.But, step pitch of every propelling, the support in these 20 meters advance support sections all need unload, moves forward, support once again, and top board is caused repeatedly support repeatedly, to herein originally just more unsettled top board cause artificial destruction, limited to its range of application greatly.
The purpose of this invention is to provide a kind of tunnel hydraulic support that can move certainly, close substantially with existing support form, both guaranteed the space and the supporting intensity in original tunnel do not need artificial unloading, carrying again, and its reach to be the systemic circulation reach.During reach, the support of art end moves forward to foremost by the circulation hanger rail and supports, and top board is not supported repeatedly, destroys, and can adapt to various more abominable geological conditionss.
Lame advanced supporting rack of the present invention as shown in Figure 1, by some shown in part 1 support and circulation actuator as shown in Figure 2 form.20 meters long tunnels of every group of supporting, according to roof condition, determine frame spacing size after, determine every group frame number.Each frame supports a girder steel by two hydraulic props as shown in Figure 3, and this root girder steel is by hinged the forming of three joints.When reach unloading, but part 2, part 3 vertical drops reduce length, so that move forward in other support, are with two rotatable Hanging roller spares 4 on the part 1, and during support work, Hanging roller is sagging, hang the circulation hanger rail; When support unloading, hanger rail reach, Hanging roller upset and drive support are hung on circulation hanger rail glide path, make support can follow the reach of ring hanger rail.The circulation actuator mainly is made up of motor shown in two circulation hanger rails shown in the part among Fig. 21, the part 2 and the circulation anchor chain shown in the part 3.The sprocket wheel of anchor chain is fixed on the two ends of two circulation hanger rails, when posterior bracket is prepared reach, unloading earlier, then along hanger rail rear end semicircle slideway change be hung in the hanger rail glide path down after, anchor chain tangles support, drives to move forward.Support move on to hanger rail foremost after, forward hanger rail top to along the semicircle slideway of hanger rail end, the stent support top board is finished a circulation then.
Description of drawings:
Fig. 1 is a structural representation of the present invention, also is front view;
Fig. 2 is a circulation actuator vertical view of the present invention;
Fig. 3 is the cross-sectional view of the present invention in the tunnel, and dotted line is depicted as a pack support and receives the schematic diagram of hanging after leaning on the circulation hanger rail when column among the figure.
Claims (5)
1, a kind of novel self-moving type lame advanced supporting hydraulic support, one group is total to supporting 20m tunnel, can adopt 500mm, 600mm, different frame spacings such as 700mm, 1000mm according to the back condition, determine one group frame number, these supports supporting simultaneously back.Hang two circulation hanger rails under the support, along with the propelling of coal-face, the support of least significant end falls and is hung on the circulation hanger rail, is drawn by anchor chain to move on to this pack support supporting roof foremost, forms the passing of systemic circulation formula and advances.
2, be with two rotatable Hanging rollers on the crossbeam of every support, during the stent support top board, it is used for hanging the circulation hanger rail, and support falls frame when moving frame, and its drives the glide path that support is rolled to the circulation hanger rail, moves forward along hanger rail.
3, a pack support is equipped with two circulation hanger rails, the hanger rail cross section is the up and down slideway of I-shaped die, sliding way is that hanger rail is hung under the support of roof supporting, the support of reach is to be hung on the glide path of hanger rail to move forward, the two ends of hanger rail are semicircle slideways, upper and lower slideway is connected together sleekly, form annular hanger rail.
4, each frame of support supports a crossbeam by two root posts, and crossbeam is by hinged the forming of three joints, and during upright supports, three joint beams become rigidity; During unloading, two ends pipe nipple and column vertical drop reduce length, so that move forward between other supports.
5, establish a circulation anchor chain between two circulation hanger rails, hang on the circulation anchor chain traction reach by motor-driven, the support of falling reach.
