Abstract
The utility model discloses a stretching device for the screen of a vibration screen, comprising a draw plate clasped and jointed with the draw hook of the screen. A draw rod axially passing through a support seat is fixed on the draw plate and is provided with adjusting nuts. A sleeve pipe for protecting the screw thread at the end of the draw rod is arranged on the free end of the draw rod beyond the adjusting nuts, and a displacement adjusting device is also provided with a locking device for preventing the adjusting nuts from loosing. The utility model, which can be used for the stretching of the screen of the vibration screen of the engineering machinery, solves the problem that the stretching device of the screen is easy to be ground by the materials and can not work normally, and enhances the operational reliability of the vibration screen.
Description
Technical field
The utility model relates to a kind of take-up device, relates in particular to the screen cloth take-up device of a kind of engineering machinery with vibratory sieve.
Background technology
The fast development of building along with highway in China, the demand of Stabilized Soil, cement concrete and the bituminous concrete that road surface pavement is used is increasing, and quality requirement is also more and more higher.On the engineering, these several concrete adopt plant mix equipment production mostly, and vibratory sieve is one of critical component wherein.Because vibratory sieve is operated in the abominable operating mode such as dust, high temperature and vibration, as the normal because wearing and tearing of material of the take-up device of tension screen cloth and cisco unity malfunction, the effort of taking a lot of work when causing maintenance and adjusting screen cloth; Or owing to vibration makes the displacement adjustment device of take-up device loosening, thereby cause screen cloth loose, the screening effect of vibratory sieve is reduced.
Summary of the invention
For the take-up device that solves screen cloth is worn and torn and the problem of cisco unity malfunction by material easily, the purpose of this utility model is: provide a kind of being not easy to be worn and torn by material, service-strong vibrating screen mesh take-up device.
For achieving the above object; the technical solution of the utility model is: the vibrating screen mesh take-up device; comprise: with the arm-tie of screen cloth drag hook clasp joint; on the screen cloth tension direction of arm-tie, be provided with displacement adjustment device; described displacement adjustment device comprises the pull bar that is installed on the arm-tie; pull rod shaft is to passing supporting seat and be provided with adjusting nut on pull bar; the free end that exceeds adjusting nut at pull bar is provided with the sleeve pipe of protecting the tie rod end screw thread, and described displacement adjustment device also has the locking device that prevents that adjusting nut is loosening.
After having adopted technique scheme, because the free-ended screw thread that exceeds adjusting nut of pull bar is subjected to the protection of sleeve pipe, the material screw thread that directly do not wear and tear, thus guaranteed the dependability of displacement adjustment device.
As a kind of improvement, for solving owing to vibration makes the displacement adjustment device of take-up device loosening, thereby cause screen cloth loosening, make the problem of the screening effect reduction of vibratory sieve, socket spring on pull bar between supporting seat and the adjusting nut, it is reliable that spring is compressed the elasticity stable of back generation, and adjusting nut is difficult for becoming flexible, thereby effectively guarantee the operate as normal of vibratory sieve.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings; the vibrating screen mesh take-up device; arm-tie 2 and screen cloth drag hook 1 clasp joint; on arm-tie 2, set firmly pull bar 7; pull bar 7 axially passes supporting seat 3 and be provided with adjusting nut 5 on pull bar 7; the free end that exceeds adjusting nut 5 at pull bar 7 is provided with the sleeve pipe 6 of protecting pull bar 7 end thread, socket compression spring 4 on the pull bar 7 between supporting seat 3 and the adjusting nut 5.
Because the free-ended screw thread that exceeds adjusting nut 5 of pull bar 7 is subjected to the protection of sleeve pipe 6, the material screw thread that directly do not wear and tear, thus guaranteed the dependability of take-up device.It is reliable that socket spring 4 on the pull bar 7 between supporting seat 3 and the adjusting nut 5, spring are compressed the elasticity stable of back generation, more is difficult for making adjusting nut 5 loosening than other locking devices such as lock washers, thereby effectively guarantee the operate as normal of vibratory sieve.
Claims (2)
