Detailed description of the invention
Generally, the utility model reclaims to combine on mud stone base plate adopts fully mechanized coal face support, support unit erection capplce is utilized to safeguard the support pattern of top board by original at sector belt place, change into the support pattern at sector belt place crib building, support unit auxiliary shoring, the supporting intensity of sector belt place top board can be increased thus.
Specifically, Fig. 2 illustrates and adopts hydraulic support of top-coal saving face withdraw sector belt supporting schematic diagram according to of the present utility model combining.As shown in Figure 2, basic support can be withdrawn from by round-link chain.Often withdraw from this support of stylobate, just a grillage is set in the origin-location of this this support of stylobate.Typically, grillage can adopt sleeper form, and its size can be 1200mm × 150mm × 150mm or 1500mm × 150mm × 150mm, and the quantity of sleeper is about 50.
The process that basic support is withdrawn from by round-link chain can be described below:
First, basic Bracket setting to be withdrawn has passing case, and the first shield support is also provided with passing case, employing is unloaded button and is coordinated round-link chain (such as, Φ 26 round-link chain) the passing case of the passing case and shield support waiting to withdraw basic support is linked together, then basic support to be withdrawn is dropped to suitable height, site operation human users support, adopt support to move forward from the mode of moving;
Subsequently, when the back timber of basic support to be withdrawn is moved to ad-hoc location (such as, apart from coal side specific range, especially, distance about 1m) time, site operation personnel install grillage (being such as " # " font grillage) under support original position, and install a post of attaching the names of pre-determined candidates (quantity and the position of propping up the post that sets up an office are determined according to field condition, and some post preferably forms certain angle in an opposite direction relative to direction, goaf) in grillage front;
Then, adjustment ceiling location, after top board has adjusted, basic support to be withdrawn has continued from moving to ad-hoc location (such as, till coal side 0.3m), adopt work plane tuning winch directly to connect the passing case of the basic support withdrawn, to this basic support tuning, holder orientation to be ajusted (in the case, can complete by individual prop, but necessary remote-controlled operation), haul support to point of loading with work plane tuning winch, entrucking is transported to ground.Thus, the process that withdraws of basic support will complete.Now, top board will be that a main pylon of attaching the names of pre-determined candidates is set to and auxiliaryly carries out roof timbering with grillage.
Basic support is withdrawn from by return channel, and return channel can be set to long 300 meters, wide 4.4 meters, high 4 meters.Generally, return channel can be arranged to enough large size, so that basic support can successfully be withdrawn from along round-link chain.
As described above, need to use shield support when basic rack restoring.Generally, shield support supports and safeguards return channel, prevents roof caving, and cooperation installs grillage and safeguards that sector withdraws hydraulic support.Three shield supports (first, second, third shield support) have been shown in Fig. 2.Hereinafter by the concrete operations mode of concrete analysis shield support.
As shown in Figure 2, three, the second, first shield support is taken a step slowly point to draw for three times and is moved on to position and (draw and move order: the three-the second-the first), the delayed first shield support certain distance of second shield support (such as, the distance of 1.75 meters), the 3rd shield support is concordant with the second shield support base;
Subsequently, before pulling shield support, first the winch gib head in return channel and the 3rd shield support are passed case to link together, be then drilled into operation in shield support by site operation personnel and fall frame, use winch draw the reach of this shield support or adopt support to move forward from the mode of moving; And pull the mode of other shield supports identical with pulling the mode of the 3rd shield support;
Then, the mode of loosing core can be adopted to withdraw support, in this case, often take out two framves and draw and move a cover frame; Also order can be adopted to withdraw support, and in this case, first, second shield support is often taken out two framves and is drawn and move once, and the 3rd shield support is often taken out a frame and drawn and move once.
As described above, often withdraw from a basic support, just can set up a grillage in the origin-location of basic support.Therefore, now supporting roof by crib protection.In the case, because grillage itself has relatively large floor space, therefore when running into mud stone base plate, grillage also can not bore ground, thus effectively increases the supporting intensity of supporting roof.
Certainly, the not pure grillage that adopts of the utility model supports supporting roof.While grillage supports, also adopt individual prop to carry out auxiliary shoring simultaneously.Such as, individual prop, up to 3.15 meters, also adopts " beam column " structure, and its crossbeam adopts the girder steel of long 0.8 meter-1.2 meters.But because grillage plays main support action, even if therefore when running into mud stone base plate, monomer supporting also can not bore ground.
Machine lane and air way is also shown in Fig. 2.Machine lane is also called Belt transport tunnel, is mainly used in carry coal, is also intake simultaneously.Air way is then return aircourse.Thus, machine lane air intake, air way return air, machine lane and air way, work plane form a system.
The utility model utilizes support unit erection capplce to safeguard the support pattern of top board by original at sector belt place, change into the support pattern at sector belt place crib building, individual prop auxiliary shoring, add the contact area with base plate, thus prevent individual prop from boring ground, and be easy to reclaim, and then reduce staff labor intensity, ensure that safe construction.
Those skilled in the art will also be appreciated that protection domain of the present utility model is not limited in above-described embodiment, allly all drop in scope of the present utility model equivalents of the present utility model.
