Abstract
The invention discloses a hoister screw tensioning mechanism which comprises a rack, a tensioning plate and a tensioning screw. The tensioning screw penetrates through the upper end of the rack, the tensioning screw and the upper end of the rack are tightly locked through matching of an upper nut which is located on the upper side of the upper end of the rack and a lower nut which is located on the lower side of the upper end of the rack, the bottom end of the tensioning screw is connected with a drag barrel, the drag barrel is fixed on the tensioning plate, and the left side of the tensioning plate and the right side of the tensioning plate are respectively provided with a rib plate which is connected with the drag barrel. According to the hoister screw tensioning mechanism, the tensioning screw drives the tensioning plate to move downward, so that a tail pulley which is connected with the tensioning plate and a mounting base on the tensioning plate through a tail shaft moves downward and a material conveyor belt is tensioned. Compared with a gravity tensioning mechanism, the hoister screw tensioning mechanism is smaller in size, smaller in occupied space and capable of meeting the requirement for being simple and convenient to use.
Description
Technical field
The present invention relates to a kind of gig screw rod stretching device.
Background technology
The stretching device of gig is for carrying out tensioning to the load-transfer device of gig.And the gig using at present mostly adopts gravity tensioning, and gravity tensioning mechanism is furnished with because of it weight box that volume is large, weight is larger, makes machine become heavy, and make the volume of whole machine also very large, thereby cannot accomplish to save space, make gig be inconvenient to use at narrow space place.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of gig screw rod stretching device that utilizes screw rod to carry out tensioning.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of gig screw rod stretching device, comprise frame, tensioning plate and tensioning screw, described tensioning screw is through the upper end of frame, this tensioning screw by be positioned at frame upper end upside upper nut and be positioned at the cooperation of lower nut and the upper end locking of frame of upper end downside of frame, the bottom of described tensioning screw and one drags cylinder to be connected, the described cylinder that drags is fixed on described tensioning plate, tensioning plate be each side provided with one with the described gusset that is connected of cylinder that drags.
Further, between the upper nut of upper end upside of described frame and the upper end of frame, be also provided with backing plate.
Further, be also provided with press strip in described frame, two of the left and right side of tensioning plate is slidably arranged at respectively between frame and press strip.
Further, the middle part of described tensioning plate is provided with a mount pad.This mount pad is for installing the tailing axle of gig.
Further, the end of described tensioning screw is provided with a jam nut, this jam nut by tensioning screw with described in drag cylinder locking.
The invention has the beneficial effects as follows: the present invention moves down tensioning plate by tensioning screw, make to move down with the tail wheel that the mount pad on tensioning plate and tensioning plate is connected by tailing axle, thereby material conveyer belt is carried out to tensioning.Than gravity tensioning mechanism, screw rod stretching device of the present invention has less volume, takies less space, has realized succinctly designing requirement easily.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, a kind of gig screw rod stretching device, comprise frame 1, tensioning plate 2 and tensioning screw 3, described tensioning screw 3 is through the upper end of frame 1, this tensioning screw 3 by be positioned at frame 1 upper end upside upper nut 4 and be positioned at the cooperation of lower nut 5 and the upper end locking of frame 1 of the upper end downside of frame 1, the bottom of tensioning screw 3 is inserted one and is dragged in cylinder 6, be connected, and the end of tensioning screw 3 is provided with a jam nut 11 with dragging cylinder 6.This jam nut 11 by tensioning screw 3 with described in drag cylinder 6 lockings.The described cylinder 6 that drags is fixed on described tensioning plate 2.Tensioning plate 2 be each side provided with one with described drag cylinder 6 gussets that are connected 7.Gusset 7 can strengthen dragging the firmness between cylinder 6 and tensioning plate 2.
In order to make to be connected more firmly between tensioning screw 3 and frame 1 upper end, between the upper nut 4 of the upper end of frame 1 upside and the upper end of frame 1, be also provided with backing plate 8.
In frame, be also provided with press strip 9, two of the left and right side of tensioning plate 2 is slidably arranged at respectively between frame 1 and press strip 9.Tensioning plate 2 can metastablely slide between frame 1 and press strip 9.
Furtherly, the middle part of tensioning plate 2 is also provided with a mount pad 10.This mount pad 10 is for installing the tailing axle of gig.
When concrete use, unscrew upper nut 4 and lower nut 5 on tensioning screw 3, then adjust the height and position of tensioning screw 3, the tensioning plate 2 being connected with tensioning screw 3 is moved down, and then the elongated hole 12 that the tailing axle being connected with tensioning plate 2 is provided with along casing is moved down, the tail wheel of installing on tailing axle moves down, thereby to material conveyer belt tensioning.When completing after tensioning, the upper nut on tensioning screw 34 and lower nut 5 are tightened respectively, make to lock between tensioning screw 3 and frame 1 upper end.Stretching device of the present invention not adopts gravity as tensile force, but utilizes tensioning screw 3 and upper nut 4 and the mutual fricative friction force of lower nut 5 to do tensile force.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification sheets of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
