Abstract
The utility model discloses a kind of freeze tunnel chain stretching device, comprises frame, and the side of described frame arranges sprocket wheel sliding feet, and described sprocket wheel sliding feet is rolled with the guidepost be fixed in described frame by the roller arranged and is connected; The front side of described sprocket wheel sliding feet is provided with sprocket wheel, is provided with anchor shaft on rear side of it; Described anchor shaft is set with tensioning spring, and the rear end of described tensioning spring is provided with spring perch; Described frame is also provided with a tension adjustment assembly that can be connected on described spring perch.Tightening device in the utility model is even at whole chain upper pulling force, can not cause de-chain on a large scale, make Operation and Maintenance convenient.The dynamics of tensioning simultaneously easily adjusts, and the stretching life-span of distribution conveyer chain is lengthened greatly, improves the useful life of chain.
Description
Technical field
The utility model relates to a kind of freeze tunnel chain stretching device.
Background technology
At present, all need to arrange tightening device in the distribution of freeze tunnel multilayer conveyer chain.Existing tightening device has two kinds: a kind of is the tightening device installing single-wheel or two-wheel composition; Another kind forms an all-in-one-piece tightening device whole passive sprocket wheels exactly.For the first form, its automatic adjustment remaining is less than normal, usually needs service personnel to carry out inspection adjustment.The all-in-one-piece tightening device of the second then in contrast, due to while tensioning the chain number of plies too many, and tensioning dynamics not easily adjusts to suitable size, easily causes de-chain accident to occur.
Utility model content
The utility model object is that the defect existed for prior art provides a kind of freeze tunnel chain stretching device.
The utility model for achieving the above object, adopt following technical scheme: a kind of freeze tunnel chain stretching device, comprise frame, the side of described frame arranges sprocket wheel sliding feet, and described sprocket wheel sliding feet is rolled with the guidepost be fixed in described frame by the roller arranged and is connected; The front side of described sprocket wheel sliding feet is provided with sprocket wheel, is provided with anchor shaft on rear side of it; Described anchor shaft is set with tensioning spring, and the rear end of described tensioning spring is provided with spring perch; Described frame is also provided with a tension adjustment assembly that can be connected on described spring perch.
Further, described tension adjustment assembly comprises a screw and an adjusting nut matched with this screw.
The beneficial effects of the utility model: the tightening device in the utility model is even at whole chain upper pulling force, can not cause de-chain on a large scale, make Operation and Maintenance convenient.The dynamics of tensioning simultaneously easily adjusts, and the stretching life-span of distribution conveyer chain is lengthened greatly, improves the useful life of chain.
Accompanying drawing explanation
The structural representation of Fig. 1 front view of the present utility model.
The structural representation of Fig. 2 birds-eye view of the present utility model.
Detailed description of the invention
Shown in Fig. 1, Fig. 2, relate to a kind of freeze tunnel chain stretching device, comprise frame 7, the side of this frame 7 is provided with sprocket wheel sliding feet 2, and sprocket wheel sliding feet 2 is rolled with the guidepost 5 be fixed in frame 7 by the roller 3 arranged and is connected; The front side of sprocket wheel sliding feet 2 is provided with sprocket wheel 1, is provided with anchor shaft 4 on rear side of it; Anchor shaft 4 is set with tensioning spring 41, the rear end of tensioning spring 41 is provided with spring perch 6; Frame 7 is also provided with a tension adjustment assembly 8 that can be connected on spring perch 6.Wherein, described tension adjustment assembly 8 comprises a screw and an adjusting nut be used in combination with this screw.
During use, the chain on freeze tunnel chain load transfer device is arranged on the sprocket wheel 3 by this device.When chain works, sprocket wheel sliding feet 2 horizontally slips along guidepost 5 by roller 3, sprocket wheel sliding feet 2 provides tensile force by the tensioning spring 41 that anchor shaft 4 is arranged, and the tensile force of spring can be regulated by the tension adjustment assembly 8 be arranged in frame 7, so just can keep tension uniform on whole chain, de-chain on a large scale can not be caused, make Operation and Maintenance convenient.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
