Description

A mounting shaft disassembly table Technical Field

[0001] This utility model relates to the field of steel manufacturing, and specifically to a mounting shaft disassembly and assembly table. Background Technology

[0002] In steel bar production lines, nylon rollers are commonly used as conveying carriers to protect the surface of the bars from scratches during transport. Nylon rollers are typically designed with a circumferential groove, and are rolled over by fitting onto a central shaft and mounting bearings. However, due to the significant weight of the bars, nylon rollers require high mechanical strength and wear resistance, resulting in a substantial increase in their size and weight. After wear, the central shaft needs to be pressed out of the inner hole of the nylon roller.

[0003] The existing disassembly and assembly setup typically involves installing a hydraulic cylinder at the top of the frame. This cylinder vertically presses the shaft of the nylon roller resting on the support plate into or out. However, due to the varying lengths of the nylon rollers, and the fact that different nylon rollers also have different shaft lengths, the existing disassembly and assembly platform cannot adjust the height of the support plate to accommodate nylon rollers with different shaft lengths. Furthermore, the support plate cannot adaptively adjust the support position of the nylon roller during the center shaft installation and alignment.

[0004] Therefore, a mounting shaft disassembly and assembly table that can be easily adjusted is needed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a mounting and disassembling platform for a nylon roller that can adjust the distance between the nylon roller to be disassembled and the upper hydraulic cylinder as needed, so as to ensure that nylon rollers of different shaft lengths can be used without using a very long hydraulic cylinder. The support position of the nylon roller can be adjusted by setting an adjustment device to adjust the spacing between the support rods, so as to meet the usage requirements.

[0006] This utility model is achieved through the following technical solution:

[0007] A mounting shaft assembly / disassembly platform includes a frame. A vertically downward-facing hydraulic cylinder is fixedly connected to the upper part of the frame. A pressure head is installed at the telescopic end of the hydraulic cylinder. Two support rods are symmetrically arranged below the hydraulic cylinder. The two ends of the support rods rest on a support plate. A lifting rod of a screw jack is fixedly connected to the lower surface of the support plate. The ends of the support rods are connected by an adjustment device to adjust the distance between the two support rods.

[0008] Furthermore, the adjustment device includes an L-shaped bracket fixed to the support plate, an adjustment screw with a horizontal threaded connection to the bracket, and a connecting block rotatably connected to one end of the adjustment screw. The connecting block is hinged to the ends of the two support rods through a pair of hinged connecting plates A and B, respectively.

[0009] Furthermore, the end of the adjusting screw away from the connecting block is provided with a manually operated handle.

[0010] Furthermore, a drive motor is provided on one side of the frame, and the drive motor synchronously drives two screw jacks through a transmission rod.

[0011] Furthermore, a limit switch is provided on the frame, and the limit switch is triggered when the lifting rod of the screw jack is raised to the limit height.

[0012] Furthermore, a control console is provided on one side of the frame.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention incorporates a screw jack, which allows the nylon roller to be placed on the support rod in a suitable manner, avoiding the need for an excessively long hydraulic cylinder. The adjustable spacing of the support rod ensures that the support roller can be positioned correctly to meet usage requirements.

[0015] By rotating the connecting block at the end of the adjusting screw in the adjusting device to hinge the connecting plate A and the connecting plate B respectively, both ends of the support rod can be freely adjusted to ensure that the spacing they are set meets the usage requirements.

[0016] For ease of operation, a handle is provided on the adjusting screw.

[0017] By using the same motor to drive the screw jack, the horizontal stability of the support rod can be ensured when supporting the screw.

[0018] Limit switches are used to prevent the screw jack from exceeding its lifting limit.

[0019] The control console allows for easy and intuitive control of the devices on the assembly / disassembly platform. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] As shown in Figures 1 and 2, a shaft mounting and disassembly platform includes a frame 10. A vertically downward-facing hydraulic cylinder 101 is fixedly connected to the upper part of the frame 10. A pressure head is installed at the telescopic end of the hydraulic cylinder 101. Two support rods 102 are symmetrically arranged below the hydraulic cylinder 101. The two ends of the support rods 102 rest on a support plate 20. The lower surface of the support plate 20 is fixedly connected to the lifting rod 311 of the screw jack 31. The ends of the support rods 102 are connected by an adjustment device 30 to adjust the distance between the two support rods 102.

[0025] Specifically, two support rods 102 are provided, respectively located on both sides of the frame 10. The two ends of the support rods 102 rest on the support plate 20, which allows the support rods 102 to be moved easily, thereby adjusting the support position for the nylon roller.

[0026] Furthermore, the adjustment device 30 includes an L-shaped bracket 301 fixed to the support plate 20, an adjustment screw 302 that is horizontally threaded through the bracket 301, and a connecting block 303 rotatably connected to one end of the adjustment screw 302. The connecting block 303 is hinged to the ends of the two support rods 102 through a pair of hinged connecting plates A304 and B305 respectively.

[0027] Furthermore, to facilitate the rotation of the adjusting screw 302, a manually operated handle 3021 is provided at the end of the adjusting screw 302 away from the connecting block 303.

[0028] Furthermore, in order to facilitate the control of the two screw jacks 31, a drive motor 103 is provided on one side of the frame 10, and the drive motor 103 synchronously drives the two screw jacks 31 through the transmission rod 1031.

[0029] Furthermore, a limit switch 104 is provided on the frame 10. When the lifting rod 311 of the screw jack 31 is lifted to the limit height, the limit switch 104 is triggered. Specifically, when the screw jack 30 is lifted to the limit height, the support plate 20 presses the limit switch 104 to prevent the screw jack 31 from exceeding its stroke.

[0030] Furthermore, a control console 40 is provided on one side of the frame 10. The control console 40 integrates the operation buttons and status display module of the hydraulic cylinder 101 and the drive motor 103.

[0031] Specifically, in use, first adjust the adjusting screw 302 to adjust the distance between the two support rods 102 to a suitable distance, then place the nylon roller to be disassembled on the support plate 20, then adjust the lead screw lift 31 to a suitable position, and drive the extension end of the hydraulic cylinder 101 to press down to perform the relevant disassembly and assembly operations.
