Abstract
The utility model discloses a kind of frame stretch-forward beam and strengthen suspension device, comprise steel I-beam, at the front end of steel I-beam, be provided with U-shaped open stand, in U-shaped open stand, be provided with installing hole, at installing hole, be provided with corresponding steady pin.The utility model adopts the front end of steel I-beam to be provided with the structure of U-shaped open stand, utilize steady pin that U-shaped open stand and a frame stretch-forward beam are closely connected together, reached extending bracket front canopy support scope, improve the requirement of support front canopy support effect, can effectively allow the basis of support at original supporting length 3650mm, adding 700mm, having reached supporting length is 4350mm.
Description
Technical field
The utility model relates to mechanical field, and especially a kind of frame stretch-forward beam strengthened suspension device.
Background technology
At present, what the fully-mechanized mining working of a lot of mines of Yong your company adopted is all not stay Triangle Coal cutting coal method, this has just caused after the complete circulation of coal mining machine cut, and frame head and tail just there will be large-area empty top, and adopt face end support to get extensible canopy, just there will be supporting situation not in place.The Jiaozishan colliery horizontal well 9706 total purchase work planes of just take are example, and because horizontal well 9706 fully-mechanized mining working trends of design length in Jiaozishan colliery are 760m, tendency length is 180m, and work plane is installed 143 of ZY2100/11/22 type shields altogether.Because adopting end to cut sth. askew, 9706 fully-mechanized mining workings do not stay Triangle Coal feed mode, so work plane has often cut a cutter coal, the termination of the frame head and tail of 9706 working faces (1# support, 2# support and 142#, 143# support) support stretches out after the extensible canopy of 600mm length, the unsupported back span that head and tail still always have more 600mm at least from, in a lot of situations, because roof pressure is larger, the coal seam of adhering to top board is easy to occur wall caving, and unsupported back span is from reaching 600mm 1200mm.For this reason, Jiaozishan coal mine fully-mechanized mining two teams, in order to prevent roof accident, once adopt DW18-30/100 or DW20-30/100 type individual prop to coordinate DJB1200 type hinged girder to set a pair of monomer supporting shed along work plane tendency, strengthen end support.But this method, there will be construction sequence many, and construction environment is dangerous, withdraw individual prop and hinged girder labour is large, affect the problems such as regular work cycle of fully-mechanized mining working.So coal-face two ends occurs that empty top problem does not obtain basic solution, this has brought very large unsafe factor for the safety in production of fully-mechanized mining working two ends.
Summary of the invention
The purpose of this utility model is: provide a kind of frame stretch-forward beam to strengthen suspension device, and its energy extending bracket front canopy support scope, the requirement that improves support front canopy support effect, to overcome the deficiencies in the prior art.
The utility model is achieved in that frame stretch-forward beam strengthens a suspension device, comprises steel I-beam, at the front end of steel I-beam, is provided with U-shaped open stand, in U-shaped open stand, is provided with installing hole, at installing hole, is provided with corresponding steady pin.
It between U-shaped open stand and steel I-beam, is welding.
Owing to having adopted technique scheme, compared with prior art, the utility model adopts the front end of steel I-beam to be provided with the structure of U-shaped open stand, utilize steady pin that U-shaped open stand and a frame stretch-forward beam are closely connected together, reached extending bracket front canopy support scope, improved the requirement of support front canopy support effect, can effectively allow the basis of support at original supporting length 3650mm, adding 700mm, having reached supporting length is 4350mm.The utility model is except procedure is simple, usability is strong, steadiness is high, and required material is also very simple, and the economic benefit of bringing also has significant benefit in fully-mechanized mining working.Two frame stretch-forward beams are strengthened to suspension devices and be fixed on one frame stretch-forward beam, can effective support top board, prevent frame head and tail generation roof fall accident, improved the safety factor of work; Prop up frame stretch-forward beam reinforcement suspension device very flexible simultaneously, can regulate supporting scope and length according to the stroke of extensible canopy, be conducive to work plane safety management.Also the safety management for other fully-mechanized mining workings provides safety management approach; And improving can work plane operating efficiency, after coal-winning machine coal cutting, can directly stretch out forestope and carry out supporting, does not affect and carries out other work, has reduced unnecessary " tapping " work, transportation individual prop and hinged girder work and the work of beating hinged girder canopy.According to down-hole Practical Calculation, average each cutter coal, the temporary lining of only beating frame head and tail just needs 30 minutes, and every bottom class is calculated by three cutter coals, just needs 90 minutes consuming time, and need 180 minutes every day, within one month, needs 90 hours.The 3rd, save a large amount of labours and drop into.This U-shaped opening steel I-beam supporting used time is short, work efficiency is large, can effectively save labour's input, has greatly accelerated the speed of construction, the carrying out that has accelerated to work regular work cycle, and the easy change of this technological innovation is new, popularization face is more extensive, has very large Applied economy to be worth.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: the structure of a frame stretch-forward beam reinforcement suspension device as shown in Figure 1, comprise that a length is 800mm, width is 120mm, be highly that the waste and old i iron of 90mm is as steel I-beam 1, used thickness is 16mm, length is that the steel plate of 400mm welds, front end at steel I-beam 1 is welded into a U-shaped open stand 2, the width of opening is 50mm, head end distance according to hole on ZY2100/11/22 type shield forestope 5 with a frame stretch-forward beam 5, in U-shaped open stand 2, apart from the 300mm place of steel I-beam 1 front end, produce installing hole 3, itself and a frame stretch-forward beam 5 are matched, and make one for the steady pin 4 of installing hole 3.
In use, utilize steady pin 5 to pierce into installing hole 3, with nut tightening steady pin 5, U-shaped open stand 2 and a frame stretch-forward beam 5 are closely connected together.
