Description
Technical field
The utility model relates to colliery driving assistive device technical field, is specifically related to a kind of U-shaped canopy tunnel New pipe subrack.
Background technology
At present, existing U-shaped steel arch shape collapsible timbering is relatively simple for structure, and supporting capacity is large, and contractibility is better, because of but use extensive in coal roadway tunneling.But the various pipelines such as the airduct used in tunnelling process, water pipe, utilize iron wire to be bundled on support and are fixed.The pipeline that the method is fixed is uneven, and leaves iron wire head, and work is not accomplished to become more meticulous, and there is potential safety hazard.
Utility model content
The purpose of this utility model is for existing U-shaped steel arch shape collapsible timbering structure Problems existing and deficiency, provides a kind of follow-on U-shaped canopy laneway pipe subrack.
The technical solution of the utility model: a kind of U-shaped canopy tunnel New pipe subrack, comprise top board, vertical connector, crossbearer and stationary fixture, riser is welded with downwards in the middle part of described top board, described vertical connector comprises base plate and side plate, base plate is vertical with side plate, wherein be bolted between base plate and described riser, and the hole of erection bolt is vertical bar hole, top board two ends arrange two fixing holes; The upper and lower solid welding respectively of side plate of described vertical connector has upper crossbearer and lower cross frame, and in the middle part of upper crossbearer and lower cross frame, be respectively provided with two installing holes respectively, in often pair of installing hole, Matching installation has stationary fixture.Described stationary fixture is U-shaped card, is connected with nut in two end thread of U-shaped card.Or described stationary fixture is elastic u-shaped card, there is gear platform in two end arranged outside of elastic u-shaped card.
The beneficial effects of the utility model: U-shaped canopy tunnel of the present utility model New pipe subrack changes the fixed form of traditional iron wire binding, and mounting means is easy, specification, and efficiency is high, good fixing effect, can Reusability.Can save cost of materials, 10 meters of iron wires can be saved in 1 meter of tunnel, and annual advance coal road about 4000 meters can save 40000 meters of iron wires.The utility model moves to correct position under loosen nut state, and then clamp nut, and in incomplete dismounting situation, realize diverse location move fixing, result of use is good, and efficiency is high.
Through use after a while, on-the-spot reflection effectiveness comparison is good, and this bracket support area is large, and support force strand is large, under various geological conditions, can use smoothly and reclaim.U-shaped canopy canopy leg transverse metal pull bar fixture clip two ends are utilized to expose screw rod, easy to operate, rapidly, structure is ingenious, significantly reduces labour hour in construction, significantly reduce worker's labour intensity, detail is raised labour efficiency, and plays effective guarantee to tunnel safety looks, and this pipe grid is safe and reliable, save money laborsaving, can promote within the scope of full ore deposit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, label 1 is top board, and 2 is fixing hole, and 3 is vertical connector, and 31 is vertical connector base plate, and 32 is vertical connector side plate, and 4 is upper crossbearer, and 5 is lower cross frame, and 6 is U-shaped card, and 7 is riser, and 8 is adjusting bolt, and 9 is vertical bar hole.
Detailed description of the invention
Embodiment 1: a kind of U-shaped canopy tunnel New pipe subrack, see Fig. 1, be welded with riser downwards in the middle part of top board, vertical connector 3 comprises base plate and side plate, and base plate is vertical with side plate.Wherein be bolted between base plate and described riser 7, and to install the hole of adjusting bolt 8 be vertical bar hole 9, thus can the height adjustment of vertical connector 3.Top board 1 two ends arrange two fixing holes 2.The upper and lower solid welding respectively of side plate of vertical connector 3 has upper crossbearer 4 and lower cross frame 5, two installing holes are respectively provided with respectively in the middle part of upper crossbearer 4 and lower cross frame 5, in often pair of installing hole, Matching installation has U-shaped card 6 as stationary fixture, is connected with nut in two end thread of U-shaped card 6.
Particularly, top board 1 is with 10mm is thick, 270mm is long, the wide steel plate of 50mm makes, and steel plate is beaten two circles that diameter is 20mm, and the distance between two circles is 200mm.
Vertical connector 3 angle iron of 300mm length.
Upper and lower crossbearer 10mm is thick, 50mm is long, the wide steel plate of 20mm makes, and steel plate is beaten two circles that diameter is 6mm, and the distance between two circles is 30mm.Bottom surface is each 1 pair of 50mm place upwards, is just pushing up 1 pair.
U-shaped card 6 adopts diameter 6mm, long 100mm round steel is made, and the long 30mm of two outer end screw rods joins corresponding nut.
U-shaped canopy canopy leg transverse metal pull bar fixture clip two ends are utilized to expose screw rod during work, the top board of New pipe subrack 1 two circles put on rear use nut be fixed firm, again pipe is put on first, second crossbearer by water pipe, airduct order, then puts U-shaped card 6 nut tightening.
Embodiment 2: content is substantially the same manner as Example 1, unlike, stationary fixture adopts elastic u-shaped card, has gear platform in two end arranged outside of elastic u-shaped card.
