Description
Technical field
The present invention relates to a kind of stretching device, especially a kind of stretching device for apron conveyor.
Background technology
Along with economic development, Automatic Conveying level is in continuous improve, and people are to producing the requirement of running velocity and the traveling comfort thereof carried also in continuous raising.The vibration produced in the operational process of apron conveyor also makes plate chain loosen accordingly, and this just improves accordingly to the requirement of tensioning.In prior art, the stretching device of apron conveyor adopts pull-type mostly, easily damages.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of stretching device for apron conveyor, make the conveying of plate-type conveying chain plate more stable, structure is simpler, and regulate more convenient, it is easier to operate.
According to technical scheme provided by the invention, the described stretching device for plate-type conveying chain, comprises tensioning frame; It is characterized in that: on described tensioning frame top by supporting the symmetrical installation of channel-section steel two groups of sliver adapter plates, sliver adapter plate is made up of upper sliver adapter plate and lower sliver adapter plate, upper sliver adapter plate installs guide rail, lower sliver adapter plate installs lower guideway, between the upper rail and lower guideway of both sides, tensioning shaft assembly is installed; Described tensioning shaft assembly comprises tensioning shaft, and slide bearing is installed at the two ends of tensioning shaft respectively, and the slide of slide bearing arranges screw rod, and during bolt rotary, slide bearing can move linearly along screw rod; Described tensioning shaft installs idler sprocket, and the slide of slide bearing is arranged between the upper rail of tensioning frame and lower guideway.
Further, between described idler sprocket and slide bearing, locating bush is set.
Further, described upper sliver adapter plate and lower sliver adapter plate favour horizontal surface and arrange, and screw rod is arranged towards one end that upper sliver adapter plate is higher, and slide bearing is arranged towards one end that lower sliver adapter plate is lower.
Further, the lower sliver adapter plate of described lower guideway one end arranges backstand.
Further, described screw rod is provided with stop nut.
The present invention has the following advantages: (1) the present invention uses the structure of pushing-type, and in using for a long time, slide block is not fragile; (2) the present invention is when making, and the structure that the structural rate of pushing-type is pull-type is simple, makes easily; (3) direction that idler sprocket of the present invention pushes away when promoting conveyer chain is downward, simple and convenient during operation, laborsaving; (4) the present invention is simple and reliable for structure, easy to maintenance.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the structural representation of described tensioning shaft assembly.
Fig. 4 is the birds-eye view of Fig. 3.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1 to 4: the described stretching device for apron conveyor comprises tensioning frame 1, supports channel-section steel 2, upper sliver adapter plate 3, lower sliver adapter plate 4, upper rail 5, lower guideway 6, tensioning shaft 7, slide bearing 8, screw rod 9, idler sprocket 10, locating bush 11, backstand 12, stop nut 13 etc.
As shown in Figure 1 and Figure 2, the present invention includes tensioning frame 1, on tensioning frame 1 top by supporting the symmetrical installation of channel-section steel 2 two groups of sliver adapter plates, sliver adapter plate is made up of upper sliver adapter plate 3 and lower sliver adapter plate 4, upper sliver adapter plate 3 installs guide rail 5, lower sliver adapter plate 4 installs lower guideway 6, between the upper rail 5 and lower guideway 6 of both sides, tensioning shaft assembly is installed; As shown in Figure 3, Figure 4, described tensioning shaft assembly comprises tensioning shaft 7, and slide bearing 8 is installed at the two ends of tensioning shaft 7 respectively, the slide of slide bearing 8 is arranged screw rod 9, and when screw rod 9 rotates, slide bearing 8 can move linearly along screw rod 9; Described tensioning shaft 7 installs idler sprocket 10, locating bush 11 is set between idler sprocket 10 and slide bearing 8; The conveyer chain winding of apron conveyor is on idler sprocket 10, and the slide of slide bearing 8 is arranged between the upper rail 5 of tensioning frame 1 and lower guideway 6.During work, when in screw rod 9 rotary course, slide bearing 8 moves linearly along upper rail 5 and lower guideway 6, and along with the movement of slide bearing 8, idler sprocket 10 also moves together, thus conveyer chain can be strained, and makes the operation of conveyer chain more steady.
Described upper sliver adapter plate 3 and lower sliver adapter plate 4 favour horizontal surface and arrange, and upper rail 5 and lower guideway 6 are also inclined to set, thus more convenient operation, uniform force.Described screw rod 9 is arranged towards one end that upper sliver adapter plate 3 is higher, and slide bearing 8 is arranged towards one end that lower sliver adapter plate 3 is lower; Thus in the course of the work, when idler sprocket 10 promotes conveyer chain, direction is downward, simple and convenient during operation, laborsaving.
The lower sliver adapter plate 4 of described lower guideway 6 one end arranges backstand 12, screw rod 9 is provided with stop nut 13, backstand 12 and stop nut 13 can block idler sprocket 10, play position-limiting action.
When the present invention is by adopting screw rod to rotate, promote the slide of slide bearing, it is easier than drawing of prior art to operate, more convenient operation, and tensioning process is more succinct, and structure is simpler.
