Description
Technical field
The utility model relates to a kind of comprehensive mining hydraulic bracket supporting quality supervising device, specifically, relates to a kind of supporting quality monitor that is applied in the comprehensive mining hydraulic bracket on the comprehensive mechanical coal mining workplace of colliery.
Background technology
At colliery comprehensive mechanical coal mining workplace, in order to guarantee supporting quality and the production safety of comprehensive mining hydraulic bracket to top board, base plate, the national regulation comprehensive mining hydraulic bracket must be that vertical top board, base plate carry out supporting to the supporting of top board, base plate, and its angle of inclination deviation can not be above ± 5 °.But in real work, people's naked eyes are to be difficult to judge whether comprehensive mining hydraulic bracket exceeds ± 5 ° the range of control that skews, comprehensive mining hydraulic bracket has the slight phenomenon of toppling over, people are difficult to find, but untimely again adjustment after the slight dip deviation appears, the comprehensive mining hydraulic bracket inclined degree will strengthen gradually, until the passive situation that frame, roof fall occur falling, cause being forced to stop production and rectifying.Especially at the fully mechanized coal face of high spud angle, problem is more outstanding, in order to overcome the above problems, prevent that comprehensive mining hydraulic bracket occurring at fully mechanized coal face falls the generation of frame, improve the supporting quality of comprehensive mining hydraulic bracket, on-the-spot under coal mine, usually adopt " tilt gauge " that comprehensive mining hydraulic bracket is carried out manual measurement and calculate the comprehensive mining hydraulic bracket dip deviation degree of this fully mechanized coal face with this, as shown in Figure 2, under the perfect condition, comprehensive mining hydraulic bracket 8 should be vertical with base plate with top board 7 respectively, but in the reality, comprehensive mining hydraulic bracket 8 has the perfect condition that departs from himself in various degree, from geometric angle, be not difficult to draw, dip deviation angle γ equals the angle β that the fully-mechanized mining working gradient or inclination alpha deduct comprehensive mining hydraulic bracket 8 and vertical direction under the virtual condition, or the angle β that dip deviation angle γ equals comprehensive mining hydraulic bracket under the virtual condition 8 and vertical direction deducts the fully-mechanized mining working gradient or inclination alpha, i.e. γ=β-α; If actual measuring and calculating back finds that dip deviation angle γ has exceeded the regulation requirement, will in time adjust comprehensive mining hydraulic bracket, guarantee production safety.Though above method is feasible, in real work, there is following shortcoming in this method: 1, need carry out data reduction, and pretty troublesome; 2, need to determine in advance the value of the fully-mechanized mining working gradient or tilt angle gamma, certain degree of difficulty is arranged; 3, under coal mine, each fully-mechanized mining working at least 80 group comprehensive mining hydraulic bracket, organizing 150 at most more, in the real work, for the dip deviation angle γ that makes calculating accurately and representative, need monitor workplace reconnaissance (if per 5 groups be a measuring point), like this, workload is very big, trouble, and have the fully mechanized coal face of certain slope, the large inclination working surface monitor staff shakiness of standing particularly, comprehensive mining hydraulic bracket has certain height again, all makes data acquisition that great difficulty is arranged, and causes the data of manual measurement not accurate enough.In real work, also there is same problem in other monitoring method, just because of this, in most colliery, country is to the requirement of comprehensive mining hydraulic bracket supporting quality and fail to obtain the especially fine execution of its production unit of coal mining enterprise, this makes most coal mining enterprise have technical management aspect problem not in place aspect the comprehensive mechanical coal mining of colliery, thereby brings the adverse consequences and the serious problems of fully mechanized coal face productive technology management.
