Abstract
The utility model relates to a side double-chain scraper conveyer tail synchronous tension chain device, while traditional side double-chain conveyer tail tension chain device uses nut and lead screw to directly tension chain, with large force and non-uniform tension force caused by asynchronous tensioning process. The utility model comprise two worm wheel worm rod decelerators, two lead screws, a spline sleeve and two baffle rings, wherein one end of each lead screw is connected with two sliding bearing bases of the tail chain wheel component, while another end forms screw transmission with the worm wheel, the decelerators are fixed at the back of the tail, the worm rods of the decelerators are connected via the spline sleeve, while two ends of the spline sleeve are clamped by the baffle rings to avoid left-and-right running. User can rotate one worm wheel worm rod decelerator to synchronously rotate another decelerator via the spline to rotate the worm wheels of same angles on the lead screw to displace the tail chain wheel components of same distance to synchronously tension chain.
Description
Technical field
The utility model relates to the colliery with the tight chain technology of slat conveyer, the synchronous chain tension adjusting device of specifically a kind of limit double chain conveyor tail.
Background technology
Traditional limit double-chain conveyor tail chain tension adjusting device generally adopts the directly tight chain of nut screw.Not only tight chain effort but also inconsistent because of the tight asynchronous chain tension that causes of chain easily.
Summary of the invention
The purpose of this utility model provides the synchronous chain tension adjusting device of a kind of limit double chain conveyor tail, but the chain tension adjusting device of laborsaving synchronous tension limit double-chain conveyor tail when this installs tight chain, conveyor chain is carried out synchronous tension regulate, avoid the jumping chain that conveyer causes because of chain tension is inconsistent, the problem of taking off chain and chain inordinate wear.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model is made of two worm type of reduction gearings, two leading screws, a spline housing, two back-up rings etc.Two plain bearing housings of two leading screw one ends and tail chain wheel assembly link together, and the other end and worm gear constitute the screw thread transmission, and worm and gear is installed in the reducing gearbox, and retarder is fixed on the tail rear portion.The worm screw of two worm type of reduction gearings links together by spline housing, and blocks the spline housing two ends by back-up ring, prevents its left and right sides play.
During use, rotate any one worm type of reduction gearing,, another retarder is rotated synchronously, make worm gear on leading screw, rotate identical angle, thereby make the tail chain wheel assembly that identical displacement be arranged, and reach the purpose of synchronously tight chain by spline housing.Owing to drive the leading screw rotation by worm type of reduction gearing, can reach the labour-saving purpose.
The beneficial effects of the utility model are, the reliability height is laborsaving, can tight synchronously chain, be adapted at working mal-condition under, and can avoid the jumping chain that conveyer causes because of chain tension is inconsistent, the problem of taking off chain and chain inordinate wear.

Fig. 1 is an integral structure work scheme drawing of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the utility model local structure scheme drawings.
The specific embodiment
Among the figure: 1. tail, 2. plain bearing housing, 3. leading screw, 4. worm gear, 5. worm screw, 6. reducing gearbox, 7. tail-wheel assembly, 8. back-up ring, 9. spline housing.
As Fig. 1, Fig. 2, shown in Figure 3, plain bearing housing (2) is assembled together with tail-wheel assembly (7), can slide front and back on tail, and leading screw (3) one ends are connected with plain bearing housing (2), worm gear (4) worm screw (5) is installed in the reducing gearbox (6), and is fixed together with tail (1).Worm gear (4) hollow constitutes the screw thread transmission with the leading screw (3) that passes wherein, when worm gear (4) rotate, leading screw (3) but just crank motion, thereby drive plain bearing housing (2) slides on tail with tail-wheel assembly (7).Worm gear (4) worm screw (5) has been formed worm type of reduction gearing with reducing gearbox (6), by rotary worm (5), can drive guide screw movement in the labour-saving.Two worm screws (5) link together by spline with spline housing (9), and block spline housing (9) two ends by back-up ring (8), prevent spline housing (9) play, so just make two worm screws (5) total energy keep identical rotatablely moving.Because in leading screw (3), worm gear (4), the worm screw (5), with a kind of part identical parameter is arranged, so during tight chain, as long as rotate any one worm screw (5), will make two worm gears (4) go up the identical angle of rotation at leading screw (3), thereby make leading screw (3) drive two plain bearing housings (2) and produce the same displacement amount, make parallel the moving of tail-wheel assembly (7) and reach the purpose of synchronously tight chain.
Claims (2)
1. the synchronous chain tension adjusting device of limit double chain conveyor tail comprises that plain bearing housing (2) and tail-wheel assembly (7) are assembled together, and is characterized in that being made up of two worm type of reduction gearings, two leading screws, a spline housing, two back-up rings etc.; Two plain bearing housings (2) of two leading screw (3) one ends and tail chain wheel assembly link together, and the other end and worm gear (4) constitute the screw thread transmission; Worm gear (4) worm screw (5) is installed in the reducing gearbox (6), and retarder is fixed on tail (1) rear portion, and the worm screw of two worm type of reduction gearings (5) links together by spline housing (9), and blocks spline housing (9) two ends by back-up ring (8).
2. the synchronous chain tension adjusting device of a kind of limit double chain conveyor tail as claimed in claim 1 is characterized by the described leading screw other end and worm gear and constitutes the screw thread transmission, is meant worm gear (4) hollow, and leading screw (3) passes and wherein constitutes the screw thread transmission.
