Abstract
A scraper chain adjusting device comprises a chain wheel, a chain wheel shaft, a large rocker arm, a fixing block, a small rocker arm, a rocker arm shaft and a hydraulic cylinder. The chain wheel is installed on the chain wheel shaft, the chain wheel shaft is installed on the large rocker arm, one end of the large rocker arm is connected with the chain wheel shaft, and the other end of the large rocker arm is connected with the rocker arm shaft, the rocker arm shaft is installed on the fixing block, the fixing block is fixed to a bottom plate, one end of the small rocker arm is installed on the chain wheel shaft, the other end of the small rocker arm is connected with the hydraulic cylinder, and the hydraulic cylinder is fixed to the bottom plate. The scraper chain adjusting device achieves the purpose of adjusting a scraper chain by driving the chain wheel to move up and down through the stretching and retracting of the hydraulic cylinder, and is simple in structure, safe, reliable and capable of greatly assisting the stable operation of the scraper chain, and the service life of the scraper chain is prolonged.
Description
Technical field
Scraper chain control apparatus of the present invention relates to coal mine scraper conveyor, is widely used in coal industry.
Background technology
Slat conveyer is widely used in driving face and the coal-face of underground coal mine.Scraper chain is when virgin work, and because the gap between adjacent chute joint is very little, slat conveyer can safe operation.But to stretch reasons such as producing elastic elongation owing to being subject to scraper chain in the plastic deformation in scraper chain use procedure and wearing and tearing, operational process, scraper chain will extend.The scraper chain extended will be piled up in the place that tension force is minimum, thus produces chain, accident such as jumping chain or card chain rupture etc.In order to ensure the safe operation of slat conveyer, the generation of Accident prevention, carries out tight chain with regard to necessary to the scraper chain extended.
The maximum adjustment scraper chain of current application has two large classes.One class is telescopic tail device, also claim automatically to adjust chain apparatus (being called for short AVK or ACTS), be exactly, at the drive end unit of scraper chain, hydraulic actuating cylinder is installed, stretching by regulator solution cylinder pressure, the degree of tightness of scraper chain can be adjusted manually or automatically in slat conveyer runs, be conducive to the working condition improving scraper chain, reduce starting power, but system be unstable.Two classes adopt chain tension adjusting device.Chain tension adjusting device strains scraper chain exactly, and what application was maximum at present is ratchet chain tensioner sheet, and structure is simple, easy to operate.Concrete details are with reference to the patent No.: 201120099448.5.If but for the larger slat conveyer of power, then after tight chain because the pressure between ratchet and slotting pawl is very large, make to move hand time dangerous.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention proposes a kind of scraper chain control apparatus.
A kind of scraper chain control apparatus, comprises sprocket wheel, sprocket shaft, large rocking arm, fixed block, small rocker, rocker shaft, hydraulic actuating cylinder.Described sprocket wheel is arranged on sprocket shaft axle; Described sprocket shaft is arranged on large rocking arm; Described large rocking arm end one end is connected with sprocket shaft, and one end is connected with rocker shaft; Described rocker shaft is arranged on fixed block; Described fixed block is fixed on base plate; Described small rocker one end is arranged on sprocket shaft, and one end is connected with hydraulic actuating cylinder; Described hydraulic actuating cylinder is fixed on base plate.
Described sprocket wheel adopts alloy steel material, is arranged on the centre of sprocket shaft, connects with bearing, can rotate around sprocket shaft, and two ends are fixing to limit its sway; Described sprocket shaft two ends symmetry connects large rocking arm and fixes.
Scraper chain control apparatus of the present invention has the following advantages:
(1) machinery is combined with hydraulic pressure, safe and reliable.
(2) can realize regulating scraper chain elasticity, not need to increase workman's labor content.
(3) dynamical element is hydraulic actuating cylinder, and transmission safely, fast.
(4) the present invention is with low cost, structure is simple, durable practicality, simple to operate.
Accompanying drawing explanation
Fig. 1 is the integral arrangement figure of scraper chain.
Fig. 2 is structural representation of the present invention.
Fig. 3 is that rocker shaft arranges schematic diagram.
Fig. 4 is sprocket wheel chain gear intention.
Fig. 5 is chain sprocket structure schematic diagram.
In figure: 1-head, 2-scraper chain, 3-tail, 4-base plate, 5-chain tension adjusting device, 501-sprocket wheel, 502-sprocket shaft, the large rocking arm of 503-, 504-fixed block, 505-rocker shaft, 506-hydraulic actuating cylinder, 507-small rocker.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described, should be understood that following examples only for illustration of the present invention but not for limiting the scope of the invention.
During use, as shown in the figure, chain tension adjusting device 5 is fixed on below head 1, spacing is left between scraper chain 2 and sprocket wheel 501, sprocket wheel 501 is placed with inductive switch, when scraper chain 2 is in relaxed state, the bagged scraper chain 2 of chain-drive section can contact with sprocket wheel 501, inductive switch on sprocket wheel 501 is triggered, hydraulic actuating cylinder 506 starts, hydraulic actuating cylinder extends, small rocker 507 and rocker shaft 505 is driven to rotate counterclockwise, rocker shaft 505 drives large Rocker arm 5 03 to rotate counterclockwise, large Rocker arm 5 03 drives sprocket shaft 502 and sprocket wheel 501 upward movement, now lax scraper chain 2 is held out against, switch closes, reach the object of tight chain,
More than show and describe this groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood; this the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the scope of protection of present invention.Application claims protection domain is defined by appending claims and equivalent thereof.
