Abstract
The utility model discloses an H-shaped steel top beam supporter, which is composed of a beam clamping frame, a supporting roller, a locking block, a horizontal wedge, etc. When in use, the top beam supporter is fixed on the non-moving H-shaped steel top beam of one pair of top beams, making the supporting roller arranged under the top beam to be moved in the shape of a cantilever, the H-shaped steel top beam to be moved is fallen and rested on the supporting roller, and the H-shaped steel top beam is moved forwards by manpower. The utility model which is favorable for safe production has the advantages of labor intensity alleviation, beam moving time saving and labor productivity enhancement.
Description
The utility model belongs to a kind of mobile device of coal mine work area supporting back timber, is suitable for moving farm labourer's word steel cap of coal wall.
According to the provisions of the relevant regulations issued by the State, should use four pairs of eight long girder steel supportings in termination, longwell conventional face both sides, to improve the supporting intensity and the stability of termination.But, since the long 3～4m of long girder steel, heavily about 100kg, and it is very inconvenient to move.Moving a beam at the scene needs the workman more than three to operate simultaneously, and four girder steels are moved in termination of every circulation needs about one and a half hours, need stop transporter about 1 hour, has influenced normally carrying out of producing.
To be that design is a kind of can replace the artificial idler pulley device of girder steel pickaback to the purpose of this utility model, and the girder steel that utilizes idler pulley to hold to lower is by manually passing forward.
The h beam cap Bracket for supporting roof beam that the utility model proposes is made of card roof beam structure and idler pulley.During use, every pair of h beam cap step type is moved, and one when mobile, another root is as articulating beam, will block roof beam structure and hang over and articulate on the beam, makes idler pulley be the cantilever-shaped below of waiting to move i iron that places, again h beam cap to be moved is fallen frame on idler pulley, rely on and manually h beam cap is passed forward.
The h beam cap Bracket for supporting roof beam of the utility model design has the following advantages:
1, can alleviate working strength of workers, manually shoulder from the past and move girder steel and change into by idler pulley and hold girder steel, manually pass forward, move a girder steel and only need 2 people.
2, raise labour productivity, move the time that girder steel needs, from about 20 minutes of past, reduce to 7～8 minutes that use behind the Bracket for supporting roof beam, and direct push-and-pull back timber, do not need the face transporter that quits work, avoided influencing production, increased the production time because of lifting beam.
3, improve workmanship, helped safety in production.

The use schematic diagram of accompanying drawing 3 h beam cap holder devices
The use schematic diagram of accompanying drawing 4 h beam cap holder devices
The utility model is further described with embodiment below in conjunction with accompanying drawing:
The h beam cap Bracket for supporting roof beam that the utility model proposes is made of card roof beam structure 2 and idler pulley 3, card roof beam structure 2 top corner ends have the claw 4 of inclined-plane folder mouthful shape, be with a movable locking piece 5 on the horizontal arm of card roof beam structure 2, latch segment 5 can be fixed on the horizontal arm of card roof beam structure by horizontal wedge 6, idler pulley 3 is installed in the lower end of the upright arm of card roof beam structure, has a gripper shoe 7 between the horizontal arm of card roof beam structure and the upright arm, as shown in Figure 1.During use, 2 Bracket for supporting roof beam can be used in each termination of work plane, four pairs of girder steels be arranged as four leading, four hysteresis, after coal-face advances one meter, before prop drawing, earlier the claw 4 of Bracket for supporting roof beam is blocked in a pair of girder steel the not cutting edge of a knife or a sword limit of the lower cross plate of mobile girder steel, the horizontal arm of latch segment 5 along the card roof beam structure advanced, the lower cross plate cutting edge of a knife or a sword limit of blocking steel I-beam is injected the wedge mouth to horizontal wedge 6 more again, tight with beating, Bracket for supporting roof beam is fixed on the not mobile girder steel 8, and idler pulley is the cantilever-shaped below of waiting to move steel I-beam 9 that places, and two joist framves one in front and one in back, fall to being placed on steel I-beam to be moved on the idler pulley, the moving girder steel that drops on the Bracket for supporting roof beam is tried hard to recommend in personnel selection, makes it to move forward reposefully to put in place, as Fig. 2, Fig. 3 and shown in Figure 4.
