Description

Technical Field

[0001] The present application belongs to the technical field of disassembly and assembly tools, and in particular relates to an auxiliary disassembly and assembly device. Background Art

[0002] Roller mill refers to the mechanical equipment used in the process of rolling steel from raw materials to finished products. It has the advantages of high mill rigidity, high strip quality, and time-saving and labor-saving roll changing. Roller mills generally include several units consisting of a rolling mill and a series of auxiliary equipment; the roll mill needs to be disassembled and replaced during maintenance. During the disassembly and assembly process, the roll mill head needs to be lifted to the specified position. The current lifting method is for one person to lift the head by hand. Since the weight of the head is 20KG to 30KG, there are safety risks such as squeezing hands and feet during the lifting process. At the same time, the labor intensity of handling is high, and it is not convenient to lift. Utility Model Content

[0003] In order to solve the technical problem that the sleeve of the current rolling mill is difficult to lift during the disassembly and assembly process, the present application provides an auxiliary disassembly and assembly device.

[0004] In order to solve the above technical problems, this application adopts the following technical solutions:

[0005] A first aspect of an embodiment of the present application provides an auxiliary disassembly and assembly device for assisting in lifting a sleeve during the disassembly and assembly process of a rolling mill. The auxiliary disassembly and assembly device comprises: a connecting rod, one end of which is provided with a threaded portion, and the threaded portion is connected to a bolt hole on the sleeve; a handle connected to the other end of the connecting rod, and after the connecting rod is connected to the sleeve, the sleeve is lifted for transportation by lifting the handle.

[0006] In some embodiments, the auxiliary disassembly and assembly device further includes a locking assembly, and the locking assembly is used to reinforce the connection between the connecting rod and the sleeve.

[0007] In some embodiments, the locking assembly includes a first locking nut, which is sleeved on the threaded portion. When fixed, the first locking nut abuts against the inner wall of the sleeve.

[0008] In some embodiments, the locking assembly includes a second locking nut, which is sleeved on the threaded portion. When fixed, the second locking nut abuts against the outer wall of the sleeve.

[0009] In some embodiments, the connecting rod is vertically connected to the middle portion of the handle.

[0010] In some embodiments, the handle is provided with anti-slip textures.

[0011] In some embodiments, the length of the connecting rod is 18 cm to 25 cm, and the length of the threaded portion is 5 cm to 10 cm.

[0022] See also Figure 1 .

[0023] Figure 1 It is a structural schematic diagram of an auxiliary disassembly and assembly device in an embodiment of the present application. As shown in the figure, the device is used to assist in transporting a sleeve 30 during the disassembly and assembly process of a rolling mill. The auxiliary disassembly and assembly device includes: a connecting rod 10, one end of which is provided with a threaded portion 11, and the threaded portion 11 is connected to the bolt hole on the sleeve 30; a handle 20, which is connected to the other end of the connecting rod 10. After the connecting rod 10 is connected to the sleeve 30, the sleeve 30 is lifted up for transportation by lifting the handle 20. By setting a connecting rod 10 and a bolt hole on the sleeve 30 for fixed connection, and then lifting the sleeve 30 through the handle 20, the original lifting operation is changed to a hand-carrying operation. At the same time, another operator holds up the sleeve 30 from below. After the sleeve 30 is lifted, the two people cooperate to install the roller changing tool, and then use the locking bolt to replace it. While facilitating the operation, it changes the operation that can only be done by one person to that which can be done by two people, reducing the labor intensity of the operators and effectively eliminating the safety risks of squeezing hands, hitting feet, etc. in the process of disassembling and assembling the sleeve 30. It has universal applicability and promotion significance.

[0024] In some embodiments, a locking bolt hole is provided on the sleeve 30. During disassembly or assembly, the bolt in the locking bolt hole is removed, and the threaded portion 11 of the connecting rod 10 is screwed into the threaded hole for fixing.

[0025] See also Figure 2 , Figure 2 It is a schematic diagram of the structure of an auxiliary disassembly and assembly device after the locking component is installed in an embodiment of the present application.

[0026] like Figure 2 As shown, in some embodiments, the auxiliary disassembly and assembly device further includes a locking assembly, and the locking assembly is used to reinforce the connection between the connecting rod 10 and the sleeve 30.

[0027] In some embodiments, the locking assembly includes a first locking nut 41, which is sleeved on the threaded portion 11. When fixed, the first locking nut 41 abuts against the inner wall of the sleeve 30. By providing the first locking nut 41, thread slippage is prevented when the connecting rod 10 is connected to the sleeve 30.

[0028] In some embodiments, the locking assembly includes a second locking nut 42, which is sleeved on the threaded portion 11. When fixed, the second locking nut 42 abuts against the outer wall of the sleeve 30. By providing the second locking nut 42, the second locking nut 42 cooperates with the first locking nut 41 to further strengthen the connection between the connecting rod 10 and the sleeve 30.

[0029] In some embodiments, the connecting rod 10 is vertically connected to the middle of the handle 20, which can ensure uniform force when lifting.

[0030] In some embodiments, the handle 20 is provided with anti-skid patterns to prevent the hand from slipping when the sleeve 30 is lifted.

[0031] In some embodiments, the length of the connecting rod 10 is 18 cm to 25 cm, and the length of the threaded portion 11 is 5 cm to 10 cm.

[0032] In some embodiments, the length of the handle 20 is 22 cm to 30 cm.

[0033] In some embodiments, the handle 20 and the connecting rod 10 are both made of Q345B steel or Q460 steel. The disassembly and assembly device is made of high-strength material and is strong and durable.

[0034] In some embodiments, connecting parts are provided at both ends of the handle 20, and the handle 20 can be lengthened by connecting the connecting parts to the sleeves.

[0035] Specifically, the connection portion can be configured as a connecting thread, and the sleeve rod is connected through the connecting thread. When a relatively heavy sleeve head 30 is encountered, the handle 20 is lengthened by the connection portion, and two people can carry the sleeve head 30 for operation.

While facilitating the operation, it changes the operation that can only be done by one person to that of two people, reducing the labor intensity of the operators, and effectively eliminating the safety risks of squeezing hands, hitting feet, etc. in the process of disassembling and assembling the sleeve, and has universal applicability and promotion significance.
