Abstract
The utility model discloses a chain tensioning device used for sewage treatment equipment. The chain tensioning device used for the sewage treatment equipment comprises a support, a support rod and a chain wheel. The support is fixedly arranged on the sewage treatment equipment; one end of the support rod is fixedly connected with the support; the other end of the support rod is fixed to the chain wheel through a hinge pin; the chain wheel is connected with a chain. Preferably, two slides are formed in the support; one end of the support rod is fixedly connected with the support through two fixed bolts passing through the two slides; when the fixed bolts are screwed off, the support rod can move along the slide direction in position. The chain tensioning device disclosed by the utility model has the beneficial effect that the tension of a chain is adjusted through the chain wheel which can be moved in position, and is suitable for various working conditions in the sewage treatment equipment; the slide structure of the chain tensioning device is simple, safe and reliable. The chain tensioning device has the technical advantages of being continuous in operation, long in service life and maintenance-free.
Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, relates in particular to a kind of chain stretching device for sewage disposal device.
Background technique
In sewage disposal device, non-metallic component is due to corrosion-resistant and extensive use, and nonmetal chain transmission parts, in sewage disposal device, comprise in scraper and being used widely.In nonmetal chain transmission, chain tension is one of key guaranteeing the normal operation of whole sewage disposal device system, nonmetal chain transmission is different from conventional chain, its pitch and engagement system have difference, need to have special chain stretching device to support the use with it.
Summary of the invention
The purpose of this utility model is to provide a kind of chain stretching device for sewage disposal device, comprise: bearing, pole, sprocket wheel, described bearing is fixed on described sewage disposal device, one end of described pole is fixedly connected with described bearing, the other end of described pole is fixed with described sprocket wheel by bearing pin, and described sprocket wheel is connected with described chain.
Preferably, have two slideways on described bearing, one end of described pole is fixedly connected with described bearing by two fixing bolts through described two slideways, and when described fixing bolt is unscrewed, the position of described pole can be moved along slideway direction.
Preferably, one end of described bearing pin is fixedly connected with described pole, and its other end is used cotter pin to fix through the center hole of described sprocket wheel.
The beneficial effects of the utility model are, the utility model carrys out the tensioning degree of adjusting chain by sprocket wheel that can mobile position, be applicable to various operating modes in sewage disposal device, its slideway structure is simple and safe and reliable, has continuous operation, long lifetime, non-maintaining technical advantage.
Accompanying drawing explanation
Fig. 1 is structural representation a of the present utility model;
Fig. 2 is structural representation b of the present utility model;
In figure, 1-bearing, 2-slotted hole, 3-fixing bolt, 4-pole, 5-sprocket wheel, 6-bearing pin.
Embodiment
In order to make the purpose of this utility model, technological scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the utility model provides a kind of chain stretching device for sewage disposal device, comprise: bearing, pole, sprocket wheel, described bearing is fixed on described sewage disposal device, one end of described pole is fixedly connected with described bearing, the other end of described pole is fixed with described sprocket wheel by bearing pin, and described sprocket wheel is connected with described chain.
Preferably, have two slideways on described bearing, one end of described pole is fixedly connected with described bearing by two fixing bolts through described two slideways, and when described fixing bolt is unscrewed, the position of described pole can be moved along slideway direction.
In the utility model, described bearing can be fixed on sewage disposal device, also can be fixed on sewage pool wall, as long as favorably situated place can.The shape of described pole is not limit, it can be galleyproof type, can be irregularly shaped, one end and the bearing of pole are fixed, the other end is fixed with a sprocket wheel, sprocket wheel can contact with the chain in equipment, and bearing is provided with the slideway of oval hole shape, can be one, can be two, can be multiple, the fixing one end of pole and bearing is provided with fixed hole, and described fixed hole and described slotted hole, by standard piece, can be that bolt is fixed, slotted hole is in a situation, pole is fixing shaky, and when slotted hole is plural, pole is fixing comparatively solid.The shape of slideway can be slotted hole shape, can be also rectangular, and the setting party of multiple slideways is to unanimously.Preferably, one end of described bearing pin is fixedly connected with described pole, and its other end is used cotter pin to fix through the center hole of described sprocket wheel.
When using, when chain is lax compared with demand, sprocket wheel need to be moved and holds out against chain to chain direction, in this time, unclamp the bolt that bearing is connected with pole, after mobile sprocket wheel satisfies the demands, clamping bolt; Otherwise, unclamp the bolt that bearing is connected with pole, after moving sprocket wheel away from chain direction and satisfying the demands, clamping bolt.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some and retouching, these improvements and modifications also should be considered as protection domain of the present utility model.
