Abstract
The utility model relates to spreading car technical field, specifically relates to a kind of spreading car chain tensioning device.Comprise slider shaft holder, U-shaped support, U-shaped internal stent both sides are provided with the guide rail run for slider shaft holder, slider shaft holder is provided with mount pad near the side of U-shaped support closed end, screw bolt passes from the closed end of U-shaped support and stretches in mount pad, the end that screw bolt is placed in mount pad is connected by self-locking screw, the length direction of screw bolt and the slider shaft holder service direction keeping parallelism on guide rail.Drive slider shaft holder to move by tightening, loosering a bolt, the position of adjustment sprocket wheel, realize chain tension adjustment.This spreading car chain tensioning device structure is simple, firmly, is easy to manufacture, reduces the dismounting number of times of bearing seat, be easy to the degree of tension debugging chain.And can ensure that the chain moment is in suitable tensioning state, the phenomenon such as stop chain climbing tooth, come off, extend the service life of spreader.
Description
Technical field
The utility model relates to spreading car technical field, specifically relates to a kind of spreading car chain tensioning device.
Background technology
What current spreading car carried feed to adopt is chain-driving material scraping plate, and sprocket wheel is connected with axle by flat key.Axle is fixed by bearing seat and envelope.For ensureing that chain has certain degree of tension in installation process, need to regulate the length needs of chain.And in use for some time, the stressed generation deformation of chain, length can increase, and needs the length of adjustment chain in good time.If adjust not in time, material scraping plate can be caused to be squeezed by forage curved, and then chain is broken.
The scheme that the degree of tension of existing adjustment chain adopts offers slotted eye on envelope adapter plate, need by the position of moving shaft holder thus the position of adjustment sprocket shaft, but each adjustment needs pine remove the bolt of fastener shaft bearing, needs repeated disassembled and assembled, wastes time and energy.
Utility model content
For the technical matters existed in prior art, the purpose of this utility model be to provide a kind of structure simple, regulate easy spreading car chain tensioning device.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of spreading car chain tensioning device, comprise slider shaft holder, U-shaped support, U-shaped internal stent both sides are provided with the guide rail run for slider shaft holder, slider shaft holder is provided with mount pad near the side of U-shaped support closed end, screw bolt passes from the closed end of U-shaped support and stretches in mount pad, the end that screw bolt is placed in mount pad is connected by self-locking screw, the length direction of screw bolt and the slider shaft holder service direction keeping parallelism on guide rail.
In this spreading car chain tensioning device, described mount pad flare shape, its peristome is covered on the side of described slider shaft holder.
In this spreading car chain tensioning device, the closed end of described U-shaped support is connected with hexagonal nut, screw bolt, through this hexagonal nut, rotates screw bolt and drives slider shaft holder to run on guide rail.
In this spreading car chain tensioning device, described U-shaped support is provided with several for the affixed mounting hole of itself and spreading car body.
Spreading car chain tensioning device of the present utility model, its beneficial effect shows:
Drive slider shaft holder to move by tightening, loosering a bolt, the position of adjustment sprocket wheel, thus realize chain tension adjustment.This spreading car chain tensioning device structure is simple, firmly, is easy to manufacture, reduces the dismounting number of times of bearing seat, be easy to the degree of tension debugging chain.And can ensure that the chain moment is in suitable tensioning state, the phenomenon such as stop chain climbing tooth, come off, extend the service life of spreader.
When U-shaped support does not arrange hexagonal nut, rotate in the tapped bore of screw bolt in U-shaped support, thus the position of adjusting slider bearing seat.When U-shaped support arranges hexagonal nut, the hole walked for screw bolt in this U-shaped support can be common through hole, can reduce the wearing and tearing of U-shaped support like this, improves the service life of U-shaped support further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spreading car chain tensioning device.
Detailed description of the invention
For further describing the utility model, below in conjunction with drawings and Examples, the utility model is described in further detail.A kind of spreading car chain tensioning device shown in Fig. 1, comprises slider shaft holder 1, U-shaped support 3, and the inner both sides of U-shaped support 3 are provided with the guide rail 2 run for slider shaft holder 1.
Slider shaft holder 1 is provided with mount pad 8 near the side of U-shaped support 3 closed end, and screw bolt 4 passes from the closed end of U-shaped support 3 and stretches in mount pad 8, and mount pad 8 flare shape, its peristome is covered on the side of slider shaft holder 1.
The end that screw bolt 4 is placed in mount pad 8 is connected by self-locking screw 6, the length direction of screw bolt 4 and the slider shaft holder 1 service direction keeping parallelism on guide rail 2.
The closed end of U-shaped support 3 is connected with hexagonal nut 5, screw bolt 4, through this hexagonal nut 5, rotates screw bolt 4 and drives slider shaft holder 1 to run on guide rail 2.
U-shaped support 3 is provided with several for the affixed mounting hole 7 of itself and spreading car body.
Above content is only to design example of the present utility model and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
