Abstract
The utility model discloses a fast dismounting tool for a bar straightener collar, which belongs to the technical field of steel rolling machinery service equipment and is used for fast dismounting a bar straightener collar. The technical scheme is that the fast dismounting tool for the bar straightener collar is composed of a collar contacting arm, connecting arms, a hydraulic cylinder fixing frame, a hydraulic cylinder and a piston barrel; wherein the collar contacting arm is in a semicircular shape, and is vertically placed; the two ends of the semicircle are respectively connected with one end of each of the two horizontally placed connecting arms; the hydraulic cylinder fixing frame is connected between the other ends of the two connecting arms; the hydraulic cylinder is mounted on the hydraulic cylinder fixing frame and is placed between the hydraulic cylinder fixing frame and the collar contacting arm; the piston barrel is arranged in the hydraulic cylinder; and the inner ring diameter of the collar contacting arm is greater than the outer diameter of a straightener roll shaft, and the outer diameter of the collar contacting arm is smaller than the outer diameter of a dismounting collar. The fast dismounting tool provided by the utility model can dismount the bar straightener collar through the relative movement of the piston barrel of the hydraulic cylinder and the collar contacting arm, is suitable for collars with different hole shapes and different diameters, has the advantages of simple structure, low manufacture cost, low work intensity, safety, convenience and high work efficiency.
Description
Technical field
The utility model relates to a kind of extracting tool of section straightener collars, belongs to rolling machinery maintenance of equipment technical field.
Background technology
In the steel rolling production process, section straightener is necessary production equipment.During section straightener, the collars of section straightener mostly is the artificial unloading in maintenance, in, heavier, maximum the reached 500kg of heavy section steel straightener collars, artificial unloading's labour intensity is very big, and safety coefficient is lower.When collars is installed, have certain interval between roll collar inner hole and axle center, if larger load is arranged during work, plastic deformation can occur in roll collar inner hole and axle surface, and dismantle collars this moment will be more difficult.Common 900 straighteners are changed a collars needs 12 workmans to use sledgehammer work 1 hour, as runs into the collars of living plastic deformation, needs the longer time.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, safe and reliable, facilitate the field personnel to operate, raise the efficiency, reduce the instrument of the quick-detachment section straightener collars of labor strength.
The technical scheme that solves the problems of the technologies described above is:
A kind of instrument of quick-detachment section straightener collars, it is comprised of collars contact arm, linking arm, hydraulic cylinder fixed mount, hydraulic cylinder, piston cylinder, the collars contact arm is semi-circular, the vertical placement, semiorbicular two ends are connected respectively with an end of the linking arm of two horizontal positioned, connecting fluid cylinder pressure fixed mount between the other end of two linking arms, and hydraulic cylinder is arranged on the hydraulic cylinder fixed mount, between hydraulic cylinder fixed mount and collars contact arm, piston cylinder is arranged in hydraulic cylinder.
The instrument of above-mentioned quick-detachment section straightener collars, the interior ring diameter of described semi-circular collars contact arm are greater than straightener roll shaft external diameter, and the outer ring diameter of semi-circular collars contact arm is less than dismounting collars external diameter.
The instrument of above-mentioned quick-detachment section straightener collars, the central axis of the piston cylinder of described hydraulic cylinder is parallel, equidistant with two linking arms, and in same plane.
The beneficial effects of the utility model are:
The utility model is applicable to the collars of different shaped jet holes, different-diameter by piston cylinder and the collars contact arm relative motion dismounting straightener collars of hydraulic cylinder.The utlity model has simple in structure, cost of manufacture is relatively low, the easy advantage of row, high efficiency of, the labour intensity that can reduce workman large to tearing open collars accommodation, safety.Common 900 straighteners are changed a collars needs 12 workmans to use sledgehammer work 1 hour, and after using this instrument, changing a collars needs 3 workmans to work 10 minutes, and labour intensity reduces greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the side view of Fig. 1.
In figure, mark is as follows: collars contact arm 1, hydraulic cylinder 2, hydraulic cylinder fixed mount 3, linking arm 4, piston cylinder 5.
The specific embodiment
The utility model is comprised of collars contact arm 1, linking arm 4, hydraulic cylinder fixed mount 3, hydraulic cylinder 2, piston cylinder 5.
Show in figure, collars contact arm 1 is semi-circular, the vertical placement, and the interior ring diameter of semi-circular collars contact arm 1 is greater than straightener roll shaft external diameter, and the outer ring diameter of semi-circular collars contact arm 1 is less than dismounting collars external diameter.
Show in figure, the semiorbicular two ends of collars contact arm 1 are connected respectively with an end of the linking arm 4 of two horizontal positioned, connecting fluid cylinder pressure fixed mount 3 between the other end of two linking arms 4, hydraulic cylinder 2 is arranged on hydraulic cylinder fixed mount 3, between hydraulic cylinder fixed mount 3 and collars contact arm 1, piston cylinder 5 is arranged in hydraulic cylinder 2, and the central axis of piston cylinder 5 is parallel, equidistant with two linking arms 4, and in same plane.
With overhead traveling crane, the utility model is sling during work, piston cylinder 5 centers and straightener roll shaft center superposition, collars contact arm 1 are enclosed within the collars inboard, and primer fluid cylinder pressure 2 oil pumps are by piston cylinder 5 and the collars contact arm 1 relative motion dismounting straightener collars of hydraulic cylinder 2.
