Description

Technical Field

[0001] The utility model belongs to the technical field of rolling mills for precious metal alloy materials, and particularly relates to a turnover device for conveniently installing or removing precious metal coils on a rolling mill tensioner. Background Art

[0002] In the prior art, during the process of processing precious metal thick plates into precious metal strip materials, as the length of the precious metal strip material increases with multi-stage rolling, precious metal coils are usually wound with the help of tensioners at both ends of the rolling mill and formed. The precious metal coils need to be turned over and transported into the warehouse between different rolling mills; in the prior art, the turnover of precious metal coils usually relies on overhead crane lifting or forklift transportation. For overhead crane lifting, the lifting rope or hook is arranged in the inner hole of the core shaft of the precious metal coil. When using a forklift for transportation, the fork is inserted into the inner hole of the core shaft of the precious metal coil; precious metal coils are characterized by large weight (up to hundreds of kilograms per roll) and a strip width smaller than the coil diameter, and the inner diameter of the core shaft of the precious metal coil is basically the same as the outer diameter of the rolling mill tensioner; combined with Figure 2 it can be seen that the lifting rope or hook of the overhead crane and the fork of the forklift occupy the installation position of the tensioner. It is necessary to first remove the lifting rope, hook or fork, and then manually install the precious metal coil on the tensioner; if you want to remove the precious metal coil from the tensioner, since the layout space of the lifting rope, hook or fork is occupied by the tensioner, it is also necessary to manually remove it first and then transport it by overhead crane lifting or forklift; due to the large weight of the precious metal coil and the lack of a suitable gripping position, manual installation and removal are not only laborious and have low production efficiency, but also pose a certain danger; therefore, it is necessary to develop a turnover device for conveniently installing or removing precious metal coils on a rolling mill tensioner. Content of the Utility Model

[0003] To overcome the deficiencies in the installation or removal of precious metal coils on the rolling mill tensioner and the turnover during the rolling process of precious metal strip materials in the prior art, the purpose of the utility model is to provide a turnover device for conveniently installing or removing precious metal coils on a rolling mill tensioner. By using this device, the installation or removal of precious metal coils on the rolling mill tensioner can be quickly implemented, and at the same time, it is convenient for the turnover of precious metal coils between different rolling mills.

[0004] The object of the present utility model is achieved as follows. The turnover device for conveniently installing or removing precious metal coils on a rolling mill comprises a bottom plate and a bearing groove. The bearing groove is formed by two side groove plates, and the side opening is in a U-shape, V-shape or an isosceles trapezoid with a larger upper part and a smaller lower part. The groove body is used to carry and support the precious metal coil. The bearing groove is arranged on the upper surface of the bottom plate. One side opening of the bearing groove corresponds to one side of the bottom plate, and the other side opening of the bearing groove corresponds to an anti-tipping baffle vertically arranged on the bottom plate. The plane of the anti-tipping baffle faces the side opening of the bearing groove. There is an upward U-shaped opening on the plane of the anti-tipping baffle, and the area of the upward U-shaped opening is smaller than the cross-sectional area of the side opening of the groove body of the bearing groove. On the front and rear sides of the lower surface of the bottom plate, 2 multi-stage lift-limiting support rods are symmetrically arranged on each side, and the bottom of the support rod has a roller. Or a guide groove for inserting the forklift fork is arranged on the lower surface of the bottom plate. The length direction of the guide groove is the same as the axial direction of the precious metal coil, and the internal height of the guide groove is greater than the thickness of the fork. The guide groove is equipped with a limit block that can be inserted and matched with it, and the limit block can be inserted between the surface of the fork and the inner wall of the guide groove.

[0005] In the turnover device of the present utility model, the bottom plate and the bearing groove form a platform for carrying and transporting precious metal coils. The height of the bottom plate is adjusted by the liftable support rods or the forklift, which is convenient for the inner hole of the core shaft of the precious metal coil to be coaxially corresponding to the tensioner. When removing the precious metal coil from the tensioner, adjust the height of the bottom plate so that the plane of the bottom plate is flush with or slightly lower than the lower end surface of the precious metal coil, and manually translate the precious metal coil to disengage from the tensioner and fall into the bearing groove on the bottom plate. When installing the precious metal coil on the tensioner, adjust the height of the bottom plate so that the inner hole of the core shaft of the precious metal coil in the bearing groove is coaxially corresponding to the tensioner, and manually translate the precious metal coil and sleeve it on the tensioner.

[0006] When the turnover device carries and transports the precious metal coil, although the two side groove plates of the bearing groove can prevent the precious metal coil from rolling, since the width of the strip of the precious metal coil is smaller than the diameter of the coil, there is a problem of easy front and rear tipping, especially at the starting stage of the turnover device transportation. For this reason, an anti-tipping baffle is arranged at the rear side of the bearing groove of the turnover device to prevent the precious metal coil from tipping backward. At the same time, if multi-stage lift-limiting support rods are arranged on the lower surface of the bottom plate, adjust the height of the symmetric support rods corresponding to the bearing groove to be higher than the state of the other symmetric support rods, so as to prevent the precious metal coil from tipping forward. If a guide groove is arranged on the lower surface of the bottom plate, after the fork is inserted into the guide groove, insert the limit block from the opening at one end of the guide groove corresponding to the bearing groove, and make the limit block located between the upper wall inside the guide groove and the upper surface of the fork, so that one end of the bottom plate corresponding to the bearing groove is lifted relatively, and the precious metal coil can also be prevented from tipping forward.

[0007] After rolling is completed, when the precious metal coil taken off from the tensioner is placed in the carrying groove and transported to the warehouse, since the upper U-shaped opening corresponding to the groove body of the carrying groove is provided on the plane of the anti-tilting baffle, both ends of the inner hole of the core shaft of the precious metal coil are in an open state, and the arrangement of the lifting rope or hook of the overhead crane or the insertion of the forklift fork during the warehousing operation will not be affected.

[0008] It can be seen that the turnover device described in the present invention has the characteristics of being simple, fast, labor-saving and efficient in installing or removing the precious metal coil by the mill tensioner compared with the prior art, and is safe and reliable during the transportation process.

[0012] The present invention will be further described below with reference to the drawings, but the present invention is not limited in any way. Any transformation or replacement based on the teachings of the present invention falls within the protection scope of the present invention.

[0013] As shown in the attached Figure 1 、 2 , the turnover device for facilitating the installation or removal of the precious metal coil by the mill tensioner includes a bottom plate 2 and a carrying groove 1; the carrying groove 1 is formed by two side groove plates with a U-shaped, V-shaped or isosceles trapezoidal groove body with a larger upper part and a smaller lower part, and the groove body is used to carry and support the precious metal coil; the carrying groove 1 is arranged on the upper surface of the bottom plate 2, one side opening of the carrying groove 1 corresponds to one side of the bottom plate 2, and the other side opening of the carrying groove 1 corresponds to the anti-tilting baffle 5 vertically arranged on the bottom plate 2; the plane of the anti-tilting baffle 5 faces the side opening of the carrying groove 1, and the upper U-shaped opening corresponding to the groove body of the carrying groove 1 is provided on the plane of the anti-tilting baffle 5, and the area of the upper U-shaped opening is smaller than the cross-sectional area of the side opening of the groove body of the carrying groove 1; two symmetrically arranged multi-stage lift-limiting support rods ( Figure 1 、 2 not shown) are respectively arranged symmetrically at the front and rear of the lower surface of the bottom plate 2, and rollers are provided at the bottom of the support rods; or guide grooves ( Figure 1 、 2(not shown), the length direction of the guide groove is the same as the axial direction of the precious metal coil, and the inner height of the guide groove is greater than the thickness of the forklift fork. The guide groove is provided with a limit block that can be inserted and matched with it, and the limit block can be inserted between the surface of the forklift fork and the inner wall of the guide groove.

[0014] With the above structure, the loading groove 1 is used to place the precious metal coil. The bottom plate 2 can adjust its height by means of a liftable support rod or with the help of a guide groove by a forklift, so that the inner hole of the core shaft of the precious metal coil corresponds coaxially with the tensioner, facilitating the installation of the precious metal coil on the tensioner or the removal from the tensioner; the front end of the loading groove 1 corresponds to the direction of the tensioner, and the anti-tipping baffle 5 provided at the rear end of the loading groove 1 can prevent the precious metal coil from tipping backward; if support rods are provided on the lower surface of the bottom plate 2, by adjusting the height, the height of the symmetric support rods corresponding to the loading groove 1 is higher than that of the other symmetric support rods, thus preventing the precious metal coil from tipping forward; if guide grooves are provided on the lower surface of the bottom plate, after the forklift forks are inserted into the guide grooves, the limit blocks are inserted through the openings at one end of the guide groove corresponding to the loading groove, and the limit blocks are located between the upper inner wall of the guide groove and the upper surface of the forklift forks, so that one end of the bottom plate corresponding to the loading groove is lifted relatively, and the precious metal coil can also be prevented from tipping forward; since the plane of the anti-tipping baffle 5 has an upward U-shaped opening corresponding to the groove body of the loading groove 1, the arrangement of the lifting ropes or hooks of the overhead crane or the insertion of the forklift forks will not be affected, facilitating the warehousing operation of the precious metal coil.

[0015] The end of the loading groove 1 corresponding to one side of the bottom plate 2 at the side of the loading groove 1 is flush with the side of the bottom plate 2; the end of the loading groove 1 corresponding to one side of the bottom plate 2 at the side of the loading groove 1 is located on the bottom plate 2, and the distance between the end of the loading groove 1 and the side of the bottom plate 2 is less than the outward extension length of the tensioner on the rolling mill; combined Figure 2 it can be seen that such an arrangement will not affect the correspondence between the loading groove 1 and the tensioner.

[0016] The two side plates of the loading groove 1 are fixedly arranged on the bottom plate 2; one side plate or both side plates of the loading groove 1 are slidably arranged on the bottom plate 2, and the opening degree of the lateral opening of the loading groove 1 can be adjusted by the relative sliding of the side plates; with such an arrangement, a loading groove 1 with a fixed or variable size of the groove body can be obtained to adapt to precious metal coils with different diameters.

[0017] A cross beam 4 is horizontally extended and arranged on the side of the anti-tipping baffle 5 away from the loading groove 1, and the cross beam 4 is fixedly connected with a reinforcing rod 3 vertically fixed on the bottom plate 2; since the weight of the precious metal coil is large and the width of the strip is less than the diameter of the coil, and in order to prevent the precious metal coil from tipping forward, the bottom plate 2 is inclined and adjusted. During transportation, the precious metal coil is basically in a state of falling toward the anti-tipping baffle 5; with such an arrangement, the support strength of the anti-tipping baffle 5 can be improved.

[0018] At one end of the bearing groove 1 corresponding to the side of the bottom plate 2, rubber ropes with hooks 7 are symmetrically arranged on the outer sides of the two side plates of the bearing groove 1 or on the bottom plate 2 corresponding to the two side plates. The symmetrically arranged rubber ropes with hooks 7 can cross and extend to the rear of the anti-tilting baffle 5 and be detachably connected to the hook fixing holes 6; combined with Figure 1 , 2 it can be seen that the rubber ropes with hooks 7 can play a role in assisting in fixing the precious metal coil.

[0019] A plurality of hook fixing holes 6 are provided, which is convenient for the rubber ropes with hooks 7 to assist in fixing precious metal coils with different diameters to obtain a more suitable tension.

[0020] The hook fixing holes 6 are arranged on the cross beam 4 or the reinforcing rod 3.

[0021] When a support rod is provided on the lower surface of the bottom plate 2, a handle or a pushing frame is arranged on the side of the bottom plate 2 away from the bearing groove 1 for easy pushing.

[0022] Working principle: In the device of the present utility model, the bearing groove 1 is arranged at one side edge of the bottom plate 2, which is convenient for installing the precious metal coil on the tensioner or receiving the precious metal coil removed from the tensioner; the two side plates of the bearing groove 1 limit the rolling of the precious metal coil. With the aid of the anti-tilting baffle 5 and the inclination adjusting mechanism under the bottom plate 2, the precious metal coil is in an inclined state towards the anti-tilting baffle 5 during the transfer process, ensuring the stability of the precious metal coil during the transfer process; the upward U-shaped opening of the anti-tilting baffle 5 makes both ends of the inner hole of the precious metal coil core shaft in an open state, which is convenient for arranging the hoisting rope or hook of the overhead crane or inserting the forklift.

[0023] Application method:

[0024] A. When receiving the precious metal coil removed from the tensioner, align the bearing groove 1 end of the turnover device with the tensioner, adjust the height of the bottom plate 2 so that the plane of the bottom plate 2 is flush with or slightly lower than the lower end face of the precious metal coil, and manually translate the precious metal coil to disengage from the tensioner and fall into the bearing groove 1 on the bottom plate 2; by adjusting the height of the support rod under the bottom plate 2, the bottom plate 2 is inclined towards the anti-tilting baffle 5, or by means of the limit block, the bottom plate 2 carried by the forklift is inclined towards the anti-tilting baffle 5; then move the turnover device to the next tensioner station or the warehousing station.

[0025] B. When installing the precious metal coil on the tensioner, the bearing groove 1 of the turnover device carries the precious metal coil and moves to the position corresponding to the tensioner, adjust the height of the bottom plate 2 so that the plane of the bottom plate 2 is flush with or slightly lower than the lower end face of the precious metal coil, and manually translate the precious metal coil to sleeved on the tensioner; during the transfer process in the rolling mill, repeatedly execute A and B.

[0026] C. When the precious metal coil is stored in the warehouse, the bearing groove 1 of the turnover device bears the precious metal coil and moves it to the warehousing station. If it is lifted by a gantry crane, the lifting rope or hook of the gantry crane is arranged in the inner hole of the core shaft of the precious metal coil, and the anti-tilting baffle 5 with an upward U-shaped opening will not affect the arrangement of the lifting rope or hook. After reliable arrangement, it can be lifted and transferred to the warehousing position. If it is transported by a forklift, the upward U-shaped opening of the anti-tilting baffle 5 facilitates the deeper insertion of the forklift forks, and the precious metal coil can be safely transferred to the warehousing position.

[0027] Since the precious metal coil is heavy and not easy to grasp, not only multiple people are required to cooperate in the transfer process by manual means, but also it is extremely easy to fall off. At the same time, there are also problems of inconvenient alignment and low efficiency when installing the precious metal coil on the tensioner. When using a gantry crane or forklift to handle the precious metal coil, when the precious metal coil is installed or removed, the inner hole of the core shaft of the precious metal coil is occupied by the previous operation, and manual installation or removal is still required. Relatively speaking, the turnover device of the present utility model can be operated by one person (at most two people cooperate) to implement the installation (including alignment during installation), removal, transfer of the precious metal coil, and cooperation with the gantry crane or forklift. The operation is simple, efficient, and safer.
