Description
Technical field
The utility model belongs to the concrete sprayer field, is specifically related to a kind of colliery and stirs the hydraulic concrete spraying machine with wet type.
Background technology
Tunnel under the coal mine is the safe space that integrates colliery transportation, pedestrian, ventilation, escaping function.So to the safety support in tunnel be necessary also be very important.The roadway support mode has a variety of: wooden supporting, steel lining, and bracket support, bolt support, bolting with wire mesh and concrete ejection supporting etc., and safe, the most reliable, the most general support pattern still is the supporting of sprayed mortar.At present, the machinery that the colliery is used for concrete spraying support is to have continued to use nearly 30 years PZ type rotator type pulp shooting machine substantially, and its advantage is that volume is little, in light weight, cheap, uses simple to operately, and the workman is easy to grasp; Shortcoming is that the work plane dust is big, and is big to worker's occupational hazards.Rotator type wet shot machine had appearred in recent years, this equipment is on PZ type basis, has set up priming apparatus at the pulp shooting machine feeding mouth, and the work plane dust can decrease in theory, but owing to be to adopt the deadly defect of pressing the wind delivering concrete, cause occurring frequent plugging in the course of work, injection work can not normally be carried out, and the workman follows the line of least resistance, dislikes trouble in real work, often also seldom add water, even do not add water, under this operating mode, job site still dust is filled the air.
Reason and the present situation of the pneumoconiosis that causes because of sprayed mortar: the dust of sprayed mortar association mainly is that respirable size is below 10 μ m, the cement grit that contains free silicon about 10%, this is one of main dust source in the mine manufacturing process, this dust very easily causes serious occupational hazards, i.e. pneumoconiosis.According to domestic part mining area field actual measurement results, the operating area mean dust concentration is generally 20～50mg/m in the sprayed mortar operation process
3About, concrete batching place and injector head place dust concentration are about 150～200mg/m
3, around the spraying machine and material loading place dust concentration even can be up to 400～1000mg/m
3More than.As seen, the dust concentration that produces of sprayed mortar national standard (10mg/m head and shoulders above
3).Make for a long time so, the miner very easily suffers from dirt (silicon) pulmoary occupation disease.According to interrelated data statistics, the Chinese coal industry is because dust pollution causes practitioner's the improper personnel reduction even more than the improper personnel reduction that causes owing to particularly serious accidents such as gas explosion, roof fall, floods; And the dust concentration that China's bolt-spary supports operation produces is also considerably beyond the dust concentration of mining and driving face produces.
What the underground mine use concrete sprayer all adopted is that wind send concrete mode, and all adopts dry type (or damp formula) wind to send technology.Thus, jetting material not only very easily produces dust, and very high concentrations, not only grievous injury miner healthy, and the working environment dust fills the air, and is extremely abominable.Because now compress the intrusion of sealing surface abrasive material and abominable operating mode with equipment, pulp shooting machine sealing plate well damage belongs to and very easily decreases accessory, the generation dust that not only leaks out, and also maintenance is frequent, the expense height.
The power source of concrete pump is motor or diesel-driven oil pump systems substantially at present.This dynamical system integrated level height is convenient to whole the movement, is applicable to field work, and is used under the coal mine just inapplicable.Lane space is narrow and small under the coal mine, and integrated level height, bulky integral device both can't be laid, and also is not easy to the artificial mobile condition of work of mining face under mine.
In recent years, along with the fast development of coal industry, the incidence of disease and the occupational health hygienic issues that reduce miner's pneumoconiosis have caused the great attention of leaders at different levels and authorities, and the dust concentration that reduces the working site significantly then is the basic outlet of dealing with problems.
