Abstract
The utility model relates to a scraper conveyer telescopic tail used for underground mining working faces in a coal mine, in particular to a scraper conveyer hydraulic telescopic tail positioning device, which comprises a tail frame body and a fixed frame body at the lower end of the tail frame and a locating pin shaft, and is characterized in that: an extended section is connected in the center of the bottom part at the rear end of the fixed frame body, a group of locating lugs is fixed on the extended section, and locating pin holes are arranged in the locating lugs; and the utility model can ensure the safe, simple and convenient operation of the working face scraper conveyer telescopic tail, and can also effectively reduce the tail height, and meet the requirements on mining in thin seams.
Description
Technical field
The utility model relates to a kind of flexible tail of slat conveyer that colliery pit mining driving surface is used that is used for, and especially relates to a kind of slat conveyer hydraulically extensible tail registration device.
Background technology
At present, colliery pit mining slat conveyer scraper chain is crossed pine can cause jumping chain accident, and tension can increase the wearing and tearing of conveyer, reduces the service life of slat conveyer, so the general tail that stretches that adopts is regulated in the tensioning of scraper chain.The locate mode of traditional flexible tail is in the both sides of drive end unit dowel hole in groups to be set.When carrying out the adjusting of scraper chain, tail stretch or contract fixing realize that by the bearing pin of dismounting both sides when actual condition operate, the power part bottom space of old man's side was little, operation is quite difficult.And the danger of wall caving being arranged in the rib side, there is great personal safety hidden danger in the installing and locating pin.On thin seam mining, because mining height is low, conveyer tail section need provide low and mild orbit for coalcutter, and to avoid the leaving triangle coal or coalcutter cut branch frame in service back timber causes the accident, original technology can't structurally satisfy above-mentioned requirements.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of driving surface slat conveyer tail safety of operation, simple, convenient that stretches that both can guarantee is provided, can effectively reduce the tail height again, satisfy the slat conveyer hydraulically extensible tail registration device that the exploitation of girdle requires.
The utility model is realized in the following way:
A kind of slat conveyer hydraulically extensible tail registration device, the fixing bracket body and the alignment pin that comprise tail support body and aircraft tail shelf lower end, it is characterized in that: be connected with an extension in this fixing bracket body rear end bottom centre, on this extension, fix one group of location otic placode, on every group of location otic placode, be equipped with dowel hole;
Respectively weld one group at fixing bracket body with tail support body both sides and be connected otic placode, connect on the otic placode and be fixed with hydraulic ram, an end of this hydraulic ram by described alignment pin be connected with described fixing bracket body, the other end is connected with the tail support body;
Bearing pin location between described tail support body and the fixing bracket body is arranged on the rear end of tail support body;
Described dowel hole is many knock holees of two rows structure.
The utility model has following effect:
1) structure uniqueness: be positioned at the aircraft tail shelf rear end between the fixed body of the utility model aircraft tail shelf body and aircraft tail shelf lower end, and adopted the bearing pin location, knock hole is many knock holees of two rows structure, realize the flexible multistage adjustment of tail, the flexible hydraulic ram that adopted between the fixed body of tail support body and lower end.
2) location is reliable: the utility model has been broken flexible in the past tail structure, and fixing bracket body rear end bottom centre is extended, and welds one group of location otic placode in the extension according to flexible stroke, has two to line up the group dowel hole on the otic placode; Fixing bracket body respectively welds one group with tail support body both sides and is connected otic placode, hydraulic ram one end is connected with fixing bracket body by bearing pin, the other end is connected with the tail support body, the tail support body is during along the fixing bracket body telescopic moving, by the location of the locating dowel pin between the otic placode of extension, bottom location, thereby guaranteed the reliability of the rearmounted location structure of flexible tail.
3) easy for operation: the utility model structure, when the scraper chain tensioning is regulated, only need take off the bearing pin on the otic placode of location, extension, bottom, fixing bracket body rear end, scraper chain is adjusted to appropriate length, reinstall bearing pin and get final product.
4) can effectively solve on the girdle coal winning technology and the orientation problem of the flexible tail of safe in operation upper scraping plate conveyer, improved the service life of conveyer simultaneously: the flexible stroke of the flexible tail both sides of the utility model hydraulic ram and the maximum adjustable amount coadaptation mutually of fixing bracket body location otic placode pin-and-hole can be provided with arbitrarily according to flexible stroke; Location otic placode extension and contraction control amount is adjustable, according to the each regulated quantity of scraper chain 10～20mm is set.
