Description

A maintenance support device for the upper blade holder of a shearing machine Technical Field

[0001] This utility model relates to the field of shearing machine maintenance technology, and in particular to a shearing machine upper blade holder maintenance support device. Background Technology

[0002] When the shearing machine on the main line of plate rolling mill is under maintenance, the upper blade holder is positioned at the top of the opening and requires support with sleepers to prevent it from falling and causing equipment failure or safety accidents. The original method of supporting the upper blade holder requires multiple people to add sleepers, and the process involves coordination among various trades, which is time-consuming and labor-intensive. There is an urgent need for an innovative support device that is simple to operate, saves time and labor, and meets on-site requirements. Therefore, this application proposes a maintenance support device for the upper blade holder of a shearing machine. Summary of the Invention

[0003] To solve the above technical problems, this utility model provides a maintenance support device for the upper blade holder of a shearing machine. When the shearing machine needs maintenance, the first and second cantilever arms can be pushed, pulled, and deflected to allow the maintenance support column to extend into the shearing machine for support. It is a simple, convenient, and safe support device suitable for preventing the upper blade holder from falling during maintenance.

[0004] The shearing machine tool holder maintenance support device in this solution includes a support and a first cantilever rotatably connected thereto. A second cantilever is rotatably connected to the end of the first cantilever away from the support, and a support cylinder is connected to the second cantilever. A maintenance support column is movably inserted into the support cylinder. The rotation axes of the first and second cantilever are both vertically arranged. The maintenance support column is vertically movably inserted into the support cylinder, and the maintenance support column has multiple first positioning holes along its height direction. At least one first positioning hole has a first positioning pin inserted into it, and the outer end of the first positioning pin extends to the upper edge of the support cylinder.

[0005] The further defined technical solution of this utility model is:

[0006] Furthermore, the maintenance support is a cylindrical structure.

[0007] Furthermore, a support plate is connected to the upper and / or lower ends of the maintenance support.

[0008] Furthermore, a second positioning pin is inserted into the support, and a second positioning hole adapted to the second positioning pin is provided on the first cantilever.

[0009] Furthermore, the support has four positioning screw holes running through it.

[0010] The beneficial effects of this utility model are: the shearing machine upper blade holder maintenance support device provided by this utility model can be installed on the outside of the shearing machine. When the shearing machine needs maintenance, the first and second cantilever arms can be pushed and pulled to allow the maintenance support to extend into the shearing machine for support. It is a simple, convenient and safe support device suitable for preventing the upper blade holder from falling during maintenance. At the same time, during non-maintenance periods, this device can be pushed and pulled back to its original position, which can be easily stored away, saving time and effort.

[0014] As shown in Figure 1, the shearing machine tool holder maintenance support device provided in this embodiment includes a support 1 and a first cantilever 2 rotatably connected thereto. A second cantilever 3 is rotatably connected to the end of the first cantilever 2 away from the support 1, and a support cylinder 4 is also connected to the end of the second cantilever 3. A cylindrical maintenance support column 5 is vertically inserted into the support cylinder 4. An upper support plate 7 and a lower support plate 8 are respectively connected to the upper and lower ends of the maintenance support column 5. In this application, the rotation axes of the first cantilever 2 and the second cantilever 3 are both vertically arranged. The maintenance support column 5 has three first positioning holes along its height direction, and a first positioning pin 6 is inserted into the uppermost first positioning hole. The outer end of the first positioning pin 6 can extend to the upper edge of the support cylinder 4. When the device is idle, the first positioning pin 6 is inserted into the first positioning hole, so that the outer bottom of the first positioning pin 6 is locked on the upper edge of the support cylinder 4, so that the maintenance support column 5 can be erected on the support cylinder 4.

[0015] In this embodiment, a second positioning pin 9 is vertically inserted into the support 1, and a second positioning hole (not shown in the figure) adapted to the second positioning pin 9 is provided on the first cantilever 2. When the second positioning pin 9 is inserted downward into the second positioning hole, the first cantilever 2 remains fixed in the state shown in Figure 1. The support 1 also has four positioning screw holes, which can be used with matching bolts to fix the support 1 to the outside of the left and right archway columns of the shearing machine for use.

[0016] Figure 2 shows a top view of the maintenance support device for the upper blade holder of the shearing machine according to this application. The dotted lines represent different states of the first cantilever 2 or the second cantilever 3. When the device is in use, as shown on the right side of Figure 2, the first cantilever 2 extends to the right, and the second positioning pin 9 fixes the first cantilever 2. At this time, the second cantilever 3 deflects from the solid line state to the dotted line state, so that the second cantilever 3 and the support cylinder 4 extend into the shearing machine. The maintenance support column 5, which can be extended up and down, supports the upper blade holder of the shearing machine, and the operator can continue to maintain the shearing machine. After the maintenance is completed, the first cantilever 2 and the second cantilever 3 can be deflected and folded to the dotted line state on the left side of Figure 2 for storage, and the upper blade holder of the shearing machine can perform normal up and down shearing operations.

[0017] It is understood that the shearing machine upper blade holder maintenance support device of this application can be installed on the outer wall of the left and right arch columns of the shearing machine. When the shearing machine needs maintenance, the first cantilever 2 and the second cantilever 3 can be pushed and pulled to extend the maintenance support 5 into the lower part of the upper blade holder inside the shearing machine to support the upper blade holder. After maintenance, the first cantilever 2 and the second cantilever 3 can be retracted to reduce the space occupied and make it very convenient to use.

[0018] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
