Description
Technical field
The utility model relates to excavation face in coal mine transport field, specifically a kind of fully-mechanized digging machine second conveyor.
Background technology
Technique of producing coal in the digging laneway of existing colliery mainly relies on fully-mechanized digging machine first conveyor to second conveyor (second conveyor utilizes connecting axle and fully-mechanized digging machine 1 to link together), and then second conveyor overlap joint belt conveyer 2 completes operation of producing coal (as shown in Figure 1).
The length of second conveyor is about 18 meters, is divided into six joint middle frames 3, and the junction of every two joint middle frames 3 is all use the brace 4 of regular length to connect.When running into upward slope in actual tunneling process, second conveyor height goes up a slope with fully-mechanized digging machine 1 and improves constantly, and causes middle frame 3 to contact with back, causes second conveyor normally not run, there is great potential safety hazard.When running into descending in tunneling process, second conveyor height constantly reduces with fully-mechanized digging machine 1 descending, causes middle frame 3 to contact with the belt conveyer 2 of its overlap joint, causes second conveyor and belt conveyer 2 all can not normally run, and impact is produced.Mainly change the height that brace 4 adjusts second conveyor at present.During replacing, use bottle gouard moved by hands to be lifted by crane at the two ends of middle frame 3, personnel dismantle former brace in the below of middle frame 3, and the height then adjusting middle frame 3 changes suitable brace, personnel have many unsafe factors when middle frame 3 times operations, and waste time and energy.
Summary of the invention
The utility model, in order to solve the inconvenience using at present and exist in second conveyor process, provides a kind of fully-mechanized digging machine second conveyor.
The utility model is achieved through the following technical solutions: fully-mechanized digging machine second conveyor, comprise six joint middle frames, be connected by brace between adjacent two middle frames, holder is respectively equipped with below first segment middle frame and second section middle frame, telescopic oil cylinder is hinged with between two holders, telescopic oil cylinder is provided with hydraulic lock, the fully-mechanized digging machine be connected with second conveyor is provided with three position four-way directional control valve and operates the control stick of hydraulic system, described three position four-way directional control valve is connected by high-pressure rubber pipe with between hydraulic lock.
During concrete use, the hydraulic power supply provided by fully-mechanized digging machine drives three position four-way directional control valve work, and operating personnel realize second conveyor middle frame hydraulic lifting function by operation three position four-way directional control valve and telescopic oil cylinder.When fully-mechanized digging machine is in tunnel uphill, downhill section, frequent demolition, installation when the belt conveyer that second conveyor and back and its overlap contacts, are not needed to change brace again.Only need operating personnel just can be adjusted the height of middle frame in real time by control stick, for fully-mechanized digging machine provides favourable condition by when uphill, downhill section and other the abnormal geological structures smoothly, improve driving progress, avoid potential safety hazard.The hydraulic control of three position four-way directional control valve, hydraulic lock and telescopic oil cylinder is that those skilled in the art easily realize.
Fully-mechanized digging machine second conveyor described in the utility model compared with prior art, has following beneficial effect:
1) meet the demands: improved second conveyor solve former second conveyor in tunnel uneven place transport difficult on the impact of driving speed, the demand to transport when meeting the digging laneway under second conveyor what geological conditions in office;
2) easy to operate: during operation, only to need driver of roadheader manipulation bar to control the telescopic oil cylinder length on second conveyor;
3) potential safety hazard and labour intensity: eliminate the place that former second conveyor is upper and lower at geological conditions base plate and convex-concave is more anxious, utilize personnel to carry out demolition, installation and change the hidden danger brought of brace, greatly reduce the labour intensity of personnel's demolition, installation simultaneously;
4) efficient: drivage efficiency is by the bad place of original geological conditions, and 0.2 meter ∕ work rises to 0.4 present meter ∕ work, improves 200%;
5) cost: the transformation of fully-mechanized digging machine second conveyor all uses waste and old Hydraulic Elements, and the leftover pieces etc. scrapping steel process, and significantly reduce cost, has saved a large amount of funds.
