Description

Technical Field

[0001] This invention relates to the field of roller conveyor maintenance technology, and in particular to an auxiliary platform for roller conveyor maintenance and a method for using the platform. Background Technology

[0002] When repairing the rollers on the hot rolling production line, it is necessary to use the overhead crane in the workshop to lift the rollers to be repaired to the ground for repair. However, due to the high demand for the use of the overhead crane in the workshop, when the repair of one roller is completed and the repair of the next roller is needed, the repair time of the roller table is often extended because the overhead crane is occupied, which affects the normal production and processing of the workshop.

[0003] In order to improve the maintenance efficiency of the roller conveyor, multiple rollers that need to be maintained can be disassembled and placed on the ground at one time using a crane. However, lifting multiple rollers to the ground at one time not only occupies a lot of floor space in the workshop, but also poses a risk of injury due to the rolling of the rollers.

[0004] In addition, both of the above maintenance methods involve disassembling the rollers and bringing them to the ground for maintenance. However, since the rollers need to be rotated and flipped during maintenance, hoisting them to the ground is not convenient for maintenance work, which leads to a longer maintenance time for the roller conveyor. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an auxiliary platform for convenient roller maintenance of roller conveyors.

[0006] The present invention adopts the following technical solution:

[0007] This invention provides an auxiliary platform for the maintenance of roller conveyors, comprising a main frame and a sub-frame. The main frame has a vertically accommodating space and is equipped with a lifting device. The sub-frame is disposed within the accommodating space of the main frame and is hinged to both sides of the main frame in the width direction. The lifting end of the lifting device contacts the sub-frame. A pair of support members are arranged parallel to each other at both ends of the main frame in the width direction. The roller is horizontally mounted on the two support members. A pair of flipping members for supporting and turning the roller is arranged parallel to each other on both sides of the sub-frame in the width direction of the main frame. The two flipping members are located directly below the roller.

[0008] Preferably, an adjustment support plate is installed on the sub-frame, and the sub-frame contacts the lifting end of the lifting device through the adjustment support plate. The adjustment support plate has a threaded hole at a position away from the lifting device.

[0009] Preferably, the support member is a fixed plate with a V-shaped groove on the top, and the roller is horizontally mounted in the V-shaped groove on the two support members.

[0010] Preferably, the flipping component is a plate with two pulleys installed at a distance from the top, and the roller is horizontally mounted on the two flipping components, with the two pulleys simultaneously abutting against the roller.

[0011] Preferably, the bottom of the main frame is provided with movable rollers, which can roll back and forth along the length of the main frame.

[0012] Preferably, it also includes a storage rack set on a horizontal ground. The storage rack is a U-shaped frame structure with one end open. The storage rack is divided into a damaged roller stacking area and a good roller stacking area. The main frame is set in the opening space of the storage rack and can move back and forth along its own length direction. The damaged roller stacking area and the good roller stacking area are set along the length direction of the main frame, and both the damaged roller stacking area and the good roller stacking area are higher than the height of the support member.

[0013] Preferably, the storage rack has a fixing thread fixed to a horizontal ground in the opening space, and an adjusting screw is threaded through the fixing thread. The adjusting screw is connected to the main frame along the length direction of the main frame, and the main frame limits the axial movement of the adjusting screw.

[0014] Preferably, four long straight rods are vertically installed on the storage rack at intervals, the four long straight rods enclosing the good roller stacking area, and the area where the long straight rods extend towards the opening of the storage rack body is the damaged roller stacking area.

[0015] The present invention also provides a method for using the roller conveyor roller maintenance auxiliary platform as described in any of the preceding claims, comprising the following steps:

[0016] S1: Using an overhead crane in the workshop, multiple rollers awaiting repair on the roller conveyor are hoisted together and transported to the damaged roller stacking area on the storage rack;

[0017] S2: Move the main frame to the damaged roller stacking area, adjust the flipping parts on the sub-frame to be directly below a roller to be repaired, lift the sub-frame using the lifting device, lift the roller to be repaired and place it horizontally on the two flipping parts.

[0018] S3: Remove the main frame from the storage rack, adjust the lifting device to lower the sub-frame and place the roller to be inspected horizontally on the two support members of the main frame;

[0019] S4: Inspect the rollers to be inspected that are horizontally mounted on two support members;

[0020] S5: The rollers that have completed the repairs are hoisted to the storage area for intact rollers by the overhead crane in the workshop;

[0021] S6: Repeat steps S2-S5 until all the rollers to be repaired in the damaged roller stacking area have been repaired.

[0022] Preferably, in step S4, if it is necessary to flip the roller to be inspected, the sub-frame is lifted by the lifting device so that the roller to be inspected is horizontally mounted on the two flipping parts and flipped. Then the lifting device is adjusted to lower the sub-frame so that the roller to be inspected is still horizontally mounted on the two support parts of the main frame and the inspection continues.

[0023] Compared with the prior art, the present invention has significant progress:

[0024] The roller maintenance auxiliary platform of the present invention can provide lateral support for the roller to be maintained by a pair of support members on the main frame. When it is necessary to flip the roller to be maintained, the sub-frame can be lifted by the lifting device, so that the roller to be maintained is laterally supported on a pair of flipping members on the sub-frame. After the roller to be maintained is flipped by the flipping members, the roller to be maintained is then laterally supported on a pair of support members on the main frame by the lowering lifting device. This provides great convenience for the maintenance of the roller and improves the maintenance efficiency of the roller conveyor.

[0025] The method of using the roller conveyor maintenance auxiliary platform of the present invention assists in the maintenance of roller conveyors. After the overhead crane hoists multiple rollers to be maintained on the roller conveyor to the damaged roller stacking area on the storage rack, the rollers only need to be hoisted to the intact roller stacking area for storage after maintenance is completed. At other times, the overhead crane is no longer needed, reducing the demand for overhead crane use and the cumulative waiting time for the overhead crane. At the same time, the rollers to be maintained and the rollers that have been maintained are stored in the damaged roller stacking area and the intact roller stacking area on the storage rack, respectively, which reduces space occupation, facilitates the "6S" management of the workshop environment, and also reduces the risk of roller injury.

[0037] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0038] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0041] like Figures 1 to 2 The image shows an embodiment of the roller conveyor maintenance auxiliary platform of the present invention.

[0042] It should be noted that, in this embodiment, the width direction of the main frame 1 is... Figure 1 The direction indicated by arrow A in the diagram is the length direction of the main frame 1. Figure 1 The direction indicated by arrow B in the diagram.

[0043] See Figure 1 and Figure 2The auxiliary platform for roller maintenance in this embodiment includes a main frame 1 and a secondary frame 2. The main frame 1 has a vertically oriented accommodating space 11 and a lifting device 12 is installed thereon. The secondary frame 2 is located within the accommodating space 11 of the main frame 1 and is hinged to both sides of the main frame 1 in the width direction. The lifting end of the lifting device 12 contacts the secondary frame 2. A pair of support members 13 are arranged parallel to each other at both ends of the main frame 1 in the width direction. The roller is horizontally mounted on the two support members 13. A pair of flipping members 21 for supporting and turning the roller are arranged parallel to each other on both sides of the secondary frame 2 in the width direction of the main frame 1. The two flipping members 21 are located directly below the roller.

[0044] The roller maintenance auxiliary platform of this embodiment can provide lateral support for the roller to be maintained by a pair of support members 13 on the main frame 1. When it is necessary to flip the roller to be maintained, the sub-frame 2 can be lifted by the lifting device 12 so that the roller to be maintained is laterally supported on a pair of flipping members 21 on the sub-frame 2. After the roller to be maintained is flipped by the flipping members 21, the roller to be maintained is then laterally supported on a pair of support members 13 on the main frame 1 by the lowering lifting device 12. This provides great convenience for the maintenance of the roller and improves the maintenance efficiency of the roller conveyor.

[0045] Preferably, in this embodiment, the lifting device 12 is a jack.

[0046] Preferably, see Figure 1 and Figure 2 An adjusting support plate 22 is installed on the sub-frame 2. The sub-frame 2 contacts the lifting end of the lifting device 12 through the adjusting support plate 22. The adjusting support plate 22 has a threaded hole at a position away from the lifting device 12. Considering the safety risk of the rollers suddenly falling when the lifting device 12 malfunctions, a screw rod 23 can be screwed into the threaded hole of the adjusting support plate 22 so that the screw rod 23 abuts against the main frame 1, thereby preventing safety accidents.

[0047] Preferably, see Figure 2 The support member 13 is a fixed plate with a V-shaped groove on the top, and the roller is horizontally mounted in the V-shaped groove on the two support members 13. The V-shaped groove allows the roller to be stably mounted horizontally on the two support members 13.

[0048] Preferably, see Figure 2 The flipping component 21 is a plate with two pulleys installed at a distance from the top. The roller is horizontally mounted on the two flipping components 21, and the two pulleys simultaneously abut against the roller. After the roller is horizontally mounted on the two flipping components 21, since the two pulleys on each flipping component 21 abut against the roller, the roller can rotate on the flipping component 21, thereby achieving the support and flipping of the roller.

[0049] Preferably, see Figure 1 and Figure 2 The bottom of the main frame 1 is provided with a movable roller 14, which can reciprocate along the length of the main frame 1. When using the roller maintenance auxiliary platform of this embodiment to assist in the maintenance of the roller to be maintained, the main frame 1 can be pushed close to the traveling trolley that is moving toward the roller maintenance auxiliary platform, thereby shortening the traveling trolley travel time and speeding up the maintenance efficiency of the roller.

[0050] Preferably, see Figure 1 The auxiliary platform for roller maintenance in this embodiment also includes a storage rack 3 set on a horizontal ground. The storage rack 3 is a U-shaped frame structure with one end open. The storage rack 3 is divided into a damaged roller stacking area F and a good roller stacking area E. The main frame 1 is set in the opening space of the storage rack 3 and can move back and forth along its own length direction. The damaged roller stacking area F and the good roller stacking area E are set along the length direction of the main frame 1, and both the damaged roller stacking area F and the good roller stacking area E are higher than the height of the support member 13.

[0051] When there are multiple rollers requiring maintenance on the roller conveyor, all rollers to be maintained can be hoisted and placed in the damaged roller stacking area F of the storage rack 3 at once by the overhead crane in the workshop. This avoids the need to wait for the overhead crane to finish its use before it can be hoisted, thus improving the efficiency of roller maintenance. At the same time, the rollers to be maintained in the damaged roller stacking area F can be moved out and maintained by moving the main frame 1 and raising or lowering the lifting device 12. After maintenance, the maintained rollers can be hoisted to the intact roller stacking area E by the overhead crane, reducing space occupation, facilitating the "6S" management of the workshop environment, and reducing the risk of roller injury.

[0052] Preferably, see Figure 1 and Figure 2 The storage rack 3 has a fixing screw 31 fixed to the horizontal ground in the opening space. An adjusting screw 32 is threaded through the fixing screw 31. The adjusting screw 32 is connected to the main frame 1 along the length direction of the main frame 1, and the main frame 1 limits the axial movement of the adjusting screw 32. The main frame 1 can be moved along the length direction by rotating the adjusting screw 32 clockwise or counterclockwise, making the movement of the main frame 1 more effortless.

[0053] Preferably, in this embodiment, the main frame 1 axially limits the adjusting screw 32 by means of a positioning nut.

[0054] Preferably, see Figure 1 Four long straight rods 33 are vertically installed on the storage rack 3 at intervals. The four long straight rods 33 enclose the intact roller stacking area E, and the area where the long straight rods 33 extend towards the opening of the storage rack 3 is the damaged roller stacking area F.

[0055] This embodiment also provides a method for using a roller conveyor roller maintenance auxiliary platform, including the following steps:

[0056] S1: Using an overhead crane in the workshop, multiple rollers awaiting repair on the roller conveyor are hoisted together and transported to the damaged roller stacking area E on the storage rack 3;

[0057] S2: Move the main frame 1 to the damaged roller stacking area F, adjust the flipping part 21 on the sub-frame 2 to be directly below a roller to be repaired, lift the sub-frame 2 by the lifting device 12, lift the roller to be repaired and set it horizontally on the two flipping parts 21.

[0058] S3: Remove the main frame 1 from the storage rack 3, adjust the lifting device 12 to lower the secondary frame 2 and make the roller to be repaired horizontally mounted on the two support members 13 of the main frame 1;

[0059] S4: Inspect the rollers to be inspected that are horizontally mounted on the two support members 13;

[0060] S5: The rollers that have completed the repairs are hoisted to the intact rollers storage area E by the overhead crane in the workshop for storage;

[0061] S6: Repeat steps S2-S5 until all the rollers to be repaired in the damaged roller stacking area F have been repaired.

[0062] The method of using the roller conveyor maintenance auxiliary platform in this embodiment assists in the maintenance of roller conveyors. After the overhead crane hoists multiple rollers to be maintained on the roller conveyor to the damaged roller stacking area F on the storage rack 3, the rollers only need to be hoisted to the intact roller stacking area E for storage after maintenance is completed. At other times, the overhead crane is no longer needed, reducing the demand for overhead crane use and the cumulative waiting time for the overhead crane. At the same time, the rollers to be maintained and the rollers that have been maintained are stored in the damaged roller stacking area F and the intact roller stacking area E on the storage rack 3, respectively, which reduces space occupation, facilitates the "6S" management of the workshop environment, and also reduces the risk of roller injury.

[0063] Preferably, in step S4, if it is necessary to flip the roller to be inspected, the sub-frame 2 is lifted by the lifting device 12 so that the roller to be inspected is horizontally mounted on the two flipping parts 21 and the roller to be inspected is flipped. Then the lifting device 12 is adjusted to lower the sub-frame 2 so that the roller to be inspected is still horizontally mounted on the two support parts 13 of the main frame 1 and the inspection continues.

[0064] The method of using the roller conveyor maintenance auxiliary platform in this embodiment greatly improves the maintenance efficiency of roller conveyors and avoids the uncontrollable downtime of the main line due to the problem of untimely maintenance of spare parts. At the same time, it greatly reduces the time occupied by the overhead crane in the workshop, creating favorable conditions for other maintenance operations and spare parts hoisting operations in the workshop.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
