Description

Technical Field

[0001] The utility model relates to the technical field of leveling machines, in particular to a lower leveling roller assembly structure which is convenient for maintenance. Background Art

[0002] The leveling machine is also called a leveling machine, a flat plate machine, a flatter machine, etc. It is mainly used in conjunction with a uncoiler. For metal plates with large elastic-plastic bending, the roller steel plate leveling machine uses the "Bausinger effect" of the material to bend the plate repeatedly multiple times, gradually reducing the deflection and finally leveling the plate.

[0003] The applicant has previously applied for an oxide scale cleaning component and a leveling machine using the cleaning component, with patent number CN202220539833.5. The frame structure is adopted, and an upper leveling roller 22 is arranged at the upper end of the frame structure, and a lower leveling roller 23 is arranged at the lower end. The upper leveling roller can be raised and lowered and tilted at an angle to adapt to the leveling of plates of different thicknesses, and the lower leveling roller is directly fixed on the lower base of the frame 21. This device solves the problem of removing the oxide scale generated during leveling. However, in actual use, the inventor also found that due to the fact that multiple lower leveling rollers are fixed to the lower base, and the presence of the upper leveling rollers will also compress the operating space above the lower leveling rollers, so that during installation, the staff needs to enter the frame structure of the frame to operate, and if one or several lower leveling rollers in the middle have problems, the leveling rollers can only be disassembled or the staff can only reach into the frame for maintenance. Due to the small space of the frame structure, sometimes the upper leveling roller needs to be disassembled to expand the operating space, which increases the difficulty of installation and maintenance, and the staff and the frame are prone to collision, which is more dangerous. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a lower leveling roller assembly structure which is convenient for maintenance.

[0005] The technical solution of this utility model is as follows:

[0006] A maintenance-friendly lower leveling roller assembly structure comprises a frame, wherein the frame is arranged in a frame shape, a lower base is arranged at the bottom of the frame, and a mounting groove is opened in the middle of the lower base along the length direction, and one end of the mounting groove passes through one side of the frame;

[0007] The lower base is provided with a mounting seat, the upper end of which is provided with a lower leveling roller, and the mounting seat can slide along the lower base and be fixed to the lower base by being driven by a driving assembly;

[0008] A limiting block is arranged at the middle position of the bottom of the mounting seat, and the limiting block extends into the mounting groove and can slide along the mounting groove along with the mounting seat.

[0009] The fixing method of the mounting seat is that a plurality of slots are provided on both sides of the moving direction of the mounting seat, and the mounting seat is fixed to the lower base by bolts at the slots.

[0010] In order to improve the stability of the mounting seat after being fixed in the frame, the length of the mounting seat along its sliding direction is greater than the distance between the two inner walls of the frame in this direction.

[0011] The specific design of the driving assembly is that the driving assembly includes a pulling handle installed on one side of the mounting seat, and the pulling handle is installed on a side surface perpendicular to the sliding direction of the mounting seat.

[0012] In order to facilitate the multi-mounting seat to apply force, it is pulled out of the rack along the lower base, and the pulling handle is provided with two strips along the plane of the mounting seat.

[0013] The drive assembly can also be designed as follows: the drive assembly includes a lead screw arranged in the installation groove, and one end of the lead screw is rotatably connected to the bottom of the installation groove through a bracket, and the other end passes through the frame and is connected to a handle;

[0014] The lead screw passes through the limiting block and is threadedly connected thereto.

[0015] In order to improve the stability of the movement of the mounting seat, guide rails are arranged on the lower bases on both sides of the mounting groove, and the mounting seat is slidably connected to the guide rails.

[0016] In order to support the mounting seat that slides out of the frame so that the lower leveling roller can be disassembled or repaired when the mounting seat slides to any position, a support assembly is movably installed at the bottom of one end of the mounting seat away from the handle and can be supported on the ground.

[0017] The specific design of the support component is that the support component includes an L-shaped groove opened at the bottom of the mounting seat, and the higher end of the L-shaped groove is hinged with a support column through a hinge seat, and the support column can be rotated to the lower end of the L-shaped groove.

[0018] In order to improve the stability of the support column, the support column is fixed to the hinge seat in the vertical direction by a locking bolt.

[0019] The beneficial effects of the utility model are as follows: the utility model is a lower leveling roller group assembly structure that is easy to maintain. First, the lower leveling roller installed in the frame can cooperate with the existing upper leveling roller to realize the leveling function of the plate; secondly, different from the existing design, the lower driving roller is installed on the mounting seat in the present scheme, and the mounting seat can slide with the lower base, replacing the existing form in which the lower leveling roller is directly installed on the fixed lower base, so that the lower leveling roller can slide out of the frame along with the mounting seat, which is convenient for the staff to install or repair the lower leveling roller outside, expands the operating space, greatly reduces the difficulty of operation, and is more conducive to the staff to observe multiple lower leveling rollers; finally, the screw of the driving component is cooperated with the limit block to facilitate the movement of the roller group and the mounting seat with heavier weight, and the support component can be used to support the mounting seat at any position when it slides out of the frame, avoiding the situation where the mounting seat needs to be dragged out of the frame for local maintenance, thereby improving the flexibility of installation and maintenance of the lower leveling roller.

[0029] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] As mentioned in the background technology, although the leveling machine previously used by the inventor solved the problem of oxide scale generated during the leveling process, during long-term use, since the frame 1 is a frame structure and the lower leveling roller 5 is installed on a fixed base, the operating space is small when disassembling or repairing the lower leveling roller 5. The staff needs to reach into the frame 1, but there is an upper leveling roller (not shown in the figure) above the frame 1, which further compresses the operating space, makes the operation more difficult, and is prone to bumps. Therefore, the inventor made improvements on the basis of the existing leveling machine and designed a new assembly structure of the lower leveling roller 5, which is explained in detail below with reference to the drawings.

[0032] This embodiment provides a lower leveling roller assembly structure that is easy to maintain, see Figure 1 , including a frame 1, and the frame 1 is set in a frame shape, that is, the four sides of the frame 1 are all open, a lower base 2 is set at the bottom of the frame 1, and a mounting groove 3 is opened in the middle of the lower base 2 along the length direction, one end of the mounting groove 3 passes through one side of the frame 1, that is, one end is set to an opening, a mounting seat 4 is set on the lower base 2, and the width of the mounting seat 4 is consistent with the width of the lower base 2, and a plurality of lower leveling rollers 5 are installed on the upper end of the mounting seat 4. The installation and fixing of the lower leveling rollers 5 can be achieved by adopting the existing technology. A plurality of lower leveling rollers 5 are arranged in parallel along the width direction of the mounting seat 4, and an upper leveling roller (not shown in the figure) is arranged at the upper end of the frame 1, but no improvement is made to the upper leveling roller, and the existing technology can be adopted, and no unnecessary details are given.

[0033] As one of the main design points of this scheme, Figure 3 The mounting seat 4 can slide along the lower base 2 and can be fixed to the lower base 2 through the drive of the driving assembly 6. A plurality of lower driving rollers are installed on the mounting seat 4 that can slide along the lower base 2, replacing the existing form of directly installing the lower leveling roller 5 directly on the fixed lower base 2. The mounting seat 4 can drive the plurality of lower leveling rollers 5 to move out of the frame 1, which facilitates the inspection or installation and disassembly of the lower leveling rollers 5 on the outside of the frame 1.

[0034] During the leveling operation of the lower leveling roller 5, the mounting seat 4 is fixedly connected to the lower base 2 to improve the stability of the lower leveling roller 5. Specifically, a plurality of slots 8 are provided on both sides of the moving direction of the mounting seat 4, and threaded holes 11 are provided in the slots 8. The mounting seat 4 and the lower base 2 are fixed by bolts at the slots 8, and a plurality of threaded holes 11 are provided at corresponding positions on both sides of the upper end surface of the mounting seat 4. Bolts are installed at the slots 8 to fix the mounting seat 4 and the lower base 2. In order to further ensure the stability of the fixing of the mounting seat 4, the length of the mounting seat 4 along its sliding direction is greater than the distance between the two inner walls of the frame 1 in this direction, so that the side frame of the frame 1 can limit the mounting seat 4 to improve stability.

[0035] In this embodiment, combined with Figure 2 The driving assembly 6 is designed in a relatively simple implementation mode, including a pulling handle 61 installed on one side of the mounting seat 4, and the pulling handle 61 is installed on the side perpendicular to the sliding direction of the mounting seat 4, that is, it is installed on the front side in the direction in which the mounting seat 4 slides out of the frame 1, and in order to facilitate the application of force by both hands or multiple people, two pulling handles 61 are installed on the side. When the lower leveling roller 5 needs to be pulled out, the bolts fixing the mounting seat 4 are unscrewed, and the pulling handle 61 is held to slide the mounting seat 4 out along the lower base 2.

[0036] Based on the above structure, combined with Figure 3 A limiting block 7 is provided at the middle position of the bottom of the mounting seat 4, and the limiting block 7 extends into the mounting groove 3, and can slide along the mounting groove 3 with the mounting seat 4. By providing the limiting block 7 and limiting the limiting block 7 by the mounting groove 3, it can be ensured that the mounting seat 4 can slide along a straight line to avoid deviation during sliding.

[0037] Embodiment 2

[0038] The difference from the first embodiment is that the Figure 4In this embodiment, a more labor-saving driving assembly 6 is adopted, and other designs are consistent with those in the first embodiment. The driving assembly 6 of this embodiment can reduce the input of personnel to move out the mounting seat 4, and can also reduce labor intensity. Specifically, the driving assembly 6 includes a lead screw 62 arranged in the mounting groove 3, and one end of the lead screw 62 is rotatably connected to the bottom of the mounting groove 3 through a bracket. The bracket can be arranged on one side of the opening end of the mounting groove 3, that is, a bracket for supporting the lead screw 62, which is not shown in the figure, and the connection method of the existing technology can be adopted. The other end passes through the frame 1 and is connected to a handle 63, that is, the lead screw 62 It is arranged horizontally in the mounting groove 3, and the lead screw 62 passes through the limit block 7 and is threadedly connected thereto, so that when the lead screw 62 rotates, under the action of the thread, the limit block 7 can slide along the mounting groove 3, which greatly reduces the driving strength compared to the design of the driving component 6 in Example 1. In order to further improve the stability of the mounting seat 4 sliding along the lower base 2, guide rails 9 are provided on the lower base 2 on both sides of the mounting groove 3. The mounting seat 4 is slidably connected to the guide rails 9, and the guide rails 9 play a guiding and limiting role for the mounting seat 4, further ensuring that the mounting seat 4 slides along a straight line to avoid displacement during movement.

[0039] On the basis of the above structure, when repairing or overhauling the lower leveling roller 5, it is sometimes not necessary to move the entire mounting seat 4 out of the frame 1, and only a partial repair is required. In order to support the front end of the mounting seat 4 in the sliding direction at any position on the path of sliding out of the frame 1, so as to facilitate the overhaul work, a support assembly 10 is movably installed at the bottom of the end of the mounting seat 4 away from the handle 63, which can be supported on the ground, that is, at the bottom of the front end in the sliding direction. In order to improve the supporting effect, at least two groups of support assemblies 10 are symmetrically arranged at the bottom of the mounting seat 4. When the front end of the mounting seat 4 slides out of the frame 1, the support assembly 10 automatically falls down and contacts the ground for support.

[0040] Specific, combined Figure 5The support assembly 10 includes an L-shaped groove 101 opened at the bottom of the mounting seat 4. The L-shaped groove 101 is divided into two parts, one part is a vertical end, which is higher and is used to install the hinge seat 102, and the other part is a horizontal end, which is lower and relatively long. The higher end (vertical end) of the L-shaped groove 101 is hinged with a support column 103 through the hinge seat 102. The support column 103 can be rotated into the lower end (horizontal end) of the L-shaped groove 101. When in a non-supporting state, the support column 103 is rotated into the L-shaped groove 101, and the support column 103 is rotated into the L-shaped groove 101, and the support column 1 The thickness of 03 does not exceed the L-shaped groove 101. When the mounting seat 4 is on the lower base 2, the end of the support column 103 away from the hinge seat 102 falls onto the lower base 2. In the process of sliding the mounting seat 4 out of the lower base 2, when the support column 103 completely leaves the lower base 2, it automatically rotates downward and is supported on the ground. In order to fix the rotation position when it is supported on the ground, the locking bolt 104 is screwed into the screw hole pre-opened at the hinge seat 102. The rotation of the hinge seat 102 is limited, so that the support column 103 is in a vertical state to improve the supporting effect.
