Abstract
The utility model discloses a board support structure for placing a tensioning board of an oil cylinder for a heading machine. One end of a slide rod (2) is fixedly connected with a support (1) while the other end of the slide rod (2) is fixedly connected with a retaining rod (3). The support (1) is in threaded or welded fixation with the slide rod (2). The slide rod (2) is also in threaded or welded fixation with the retaining rod (3). The support (1) has two structures respectively for welding and bolt connecting conditions. The utility model provides the board support structure, wherein the tensioning board of the oil cylinder can not only draw materials nearby and the stroke of tension of the oil cylinder of the heading machine is adjusted, but also solve the problem that the board support structure is easy to lose in long-term use. The board support structure is simple and reasonable in structural design and strong in practicality, and the using performance of the tensioning board of the oil cylinder can be improved, the work efficiency is improved, the time is saved and the waste is reduced.
Description
Technical field
The utility model relates to a kind of clamp seat structure, particularly relates to the clamp seat structure that a kind of development machine is placed oil cylinder tensioning clamp.
Background technology
At present, the tightening device that domestic first conveyer of digging machine adopts all adopts double lead-screw tensioning or two oil cylinder tensioning.For the development machine that uses the oil cylinder tensioning, existing type is temporarily without the clamp seat structure; And long-term use uneven because of load, cause two chain degree of tightness immoderation or stretched length not to wait situation to happen occasionally in the course of the work, needs often to adjust the oil cylinder stroke of tension, increase and decrease oil cylinder tensioning clamp; Because the down-hole situation is complicated, the oil cylinder tensioning clamp of increase and decrease is difficult for access, easily loses, and affects the operation and maintenance of machine.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of in cylinder tensioning device increase and decrease oil cylinder tensioning clamp situation, and simplicity of design, the development machine that easy for installation, cost is low, safe and reliable are placed the clamp seat structure of oil cylinder tensioning clamp.
In order to solve the problems of the technologies described above, the development machine that the utility model provides is placed the clamp seat structure of oil cylinder tensioning clamp, and slide bar one end is fixedly connected with bearing, and the other end of described slide bar is fixedly connected with lever.
Described bearing adopts screw thread or is welded and fixed with described slide bar and is connected, and described slide bar adopts screw thread or is welded and fixed with described lever and is connected.
Described bearing is welded structure formula bearing or flange arrangement formula bearing.
The diameter of described slide bar is less than the diameter of tensioning hydro-cylinder cylinder bar, and greater than the clamp opening size, the length of described slide bar is greater than the stroke of tensioning hydro-cylinder.
Described lever is set to described lever to the stroke of described bearing distance greater than tensioning hydro-cylinder described slide bar is upper.
The angular range that described slide bar becomes with horizontal surface is to 180 degree for 0 degree.
Adopt the clamp seat structure of the development machine placement oil cylinder tensioning clamp of technique scheme, utilize the skew of the deadweight of tensioning clamp or center of gravity to make the clamp can be because of non-artificial movement landing from the clamp seat structure, fast changeable tensioning clamp, realize more timely the chain tension adjusting, improve the service life of tightening device, reduce fault rate.
The novel development machine of this use is placed the clamp seat structure of oil cylinder tensioning clamp, has following characteristics:
1, structure design is simple, reasonable, easy for installation, reliable, practical;
2, prevent the clamp loss, be convenient to clamp and change, reduce the maintenance and repair difficulty, save cost, promote work efficiency.
In sum, the utility model is to make oil cylinder tensioning clamp can not only realize drawing materials nearby in time to adjust development machine oil cylinder stroke of tension, and can avoid the clamp seat structure of easy problem of losing in long-term use procedure.Structure design is simple, and is rationally practical, can improve the in-use performance of tensioning hydro-cylinder clamp, increases work efficiency, and saves time, and cuts the waste.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, slide bar 2 one ends are fixedly connected with bearing 1, the other end of slide bar 2 is fixedly connected with lever 3, bearing 1 adopts screw thread or is welded and fixed with slide bar 2 and is connected, slide bar 2 adopts screw thread or is welded and fixed with lever 3 and is connected, the diameter of slide bar 2 is less than the diameter of tensioning hydro-cylinder cylinder bar, size greater than the opening 5 of clamp 4, the length of slide bar 2 is greater than the stroke of tensioning hydro-cylinder, to the stroke of bearing 1 distance greater than tensioning hydro-cylinder, the centerline direction of lever 3 is level to lever 3 at the upper lever 3 that is set to of slide bar 2.
Referring to Fig. 7, this programme for clamp 4 types as shown in Figure 7, require K＜D1.The outer ring of clamp 4 can be circle, polygon or circle and the shape such as is combined with polygon, and the outer ring maximum gauge of clamp 4 is Dmax.
Referring to Fig. 8 and Fig. 9, the diameter D＜D1 of slide bar 2, the maximum diameter d＜K of lever 3, the center of gravity of slide bar 2 gets distance H to fixture〉Dmax/2, effectively place the stroke that clamp space length L is not less than tensioning hydro-cylinder.
Referring to Figure 10, during installation, slide bar 2 is that 0 degree is to 180 degree with the scope of horizontal plane angle α.
By aforesaid operations, development machine is worked under complex working condition, and clamp 4 loss that can not come off reaches and prevents that clamp 4 from losing, and is convenient to clamp 4 and changes, and reduces the maintenance and repair difficulty, saves cost, promotes work efficiency.
