Abstract
The utility model relates to an automatic tension device, in particular to an automatic tension device applicable to equipment such as a scraper conveyor, an en masse conveyor, a submerged chain conveyor and the like. The automatic tension device comprises a tension frame, a tension shaft bearing block, a tension spring, a jack and a slider, wherein slide guides are arranged on two sides of the tension frame respectively; a bottom plate at two ends of the tension spring is fixedly connected with the tension shaft bearing block and the jack respectively; the sliders are fixed respectively on two sides of the bottom plate connected with the jack and can slide on the slide guides; and the jack presses to enable the tension spring to be in a compressed state, and then the tension shaft bearing block is pushed to move so as to achieve a tension effect. According to the automatic tension device, pre-tension is performed on a scraper chain constantly by using the compression performance of the spring, so that the problems of chain stick-slip, unstable initial tension, operational impact and the like are solved effectively.
Description
Technical field
The utility model relates to a kind of tightening device, specifically a kind of automatic takeup that is applicable to the equipment such as slat conveyer, embedded scraper transporter, dragveyer.
Background technology
Slat conveyer is in operational process, and the free tightness of scraper chain, weares and teares, jumps chain, the decisive relation of impacting, collided with to itself and sprocket engagement.Because elasticity can not be adjusted automatically, so often occur to jump chain, the phenomenon of impacting, collide with, cause equipment to change in early days, and accelerate because tension causes sprocket wheel degree of wear.
Utility model content
Scraper chain elasticity for prior art middle scraper conveyer can not be adjusted automatically, the problem that chain, the phenomenon of impacting, collide with often occur to jump, the utility model provides a kind of automatic takeup that is applicable to the equipment such as slat conveyer, embedded scraper transporter, dragveyer.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automatic takeup, comprise tensioning frame, tensioning shaft bearing seat, tensioning spring, jack and slide block, the both sides of described tensioning frame are respectively equipped with slide rail, the base plate at tensioning spring two ends is fixedly connected with jack with tensioning shaft bearing seat respectively, the both sides of the base plate being wherein connected with jack are fixed with respectively slide block, slide block can slide on slide rail, and jack has been pressed and made tensioning spring in compressive state, and then promotion tensioning shaft bearing seat moves to reach tension effects;
Described tensioning spring is parallel with slide rail;
Described jack is fixed on jack pad assembly.
The beneficial effects of the utility model:
The utility model utilizes the performance of tensioning spring compression, scraper chain is carried out to pretension constantly, efficiently solve scraper chain and climb chain, initial tension shakiness, the problems such as operational shock, during work, jack has been pressed certain altitude to make tensioning spring in compressive state, tensioning spring promotion tensioning shaft bearing seat moves backward and reaches the object of tensioning, because spring is all the time in tensioning state, when chain fluffs, spring promotion tensioning shaft automatically moves back, thereby reach the object of auto-tensioning, only need jack have been pressed to one section every a period of time, easy to operate, be easy to safeguard, long service life.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
1, tensioning frame, 2, slide rail, 3, tensioning shaft bearing seat, 4, tensioning spring, 5, jack, 6, jack pad assembly, 7, slide block.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is further elaborated.
As shown in the figure: a kind of automatic takeup, comprise tensioning frame 1, tensioning shaft bearing seat 3, tensioning spring 4, jack 5 and slide block 7, the both sides of described tensioning frame 1 are respectively equipped with slide rail 2, the base plate at tensioning spring 4 two ends is fixedly connected with jack 5 with tensioning shaft bearing seat 3 respectively, the both sides of the base plate being wherein connected with jack 5 are fixed with respectively slide block 7, slide block 7 can slide on slide rail 2, jack 5 has been pressed and has been made tensioning spring 4 in compressive state, and then promotion tensioning shaft bearing seat 3 moves to reach tension effects; Described tensioning spring 4 is parallel with slide rail 2; Described jack 5 is fixed on jack pad assembly 6.
Tensioning spring 4 is fixed between tensioning shaft bearing seat 3 and jack 5, the slide block 7 being connected with the base plate of tensioning spring 4 can slide on slide rail 2, during work, jack 5 has been pressed certain altitude to make tensioning spring 4 in compressive state, tensioning spring 4 promotes tensioning shaft bearing seat 3 and moves backward and reach the object of tensioning, because tensioning spring 4 is all the time in tensioning state, when chain fluffs, tensioning spring 4 promotes tensioning shaft and automatically moves back, thereby reach the object of auto-tensioning, only need jack 5 have been pressed to one section every a period of time.
