Abstract
Description
Technical Field
[0001] The present invention relates to the field of rubber wheel disassembly, and in particular to a rubber wheel disassembly tool. Background Art
[0002] Rubber wheels are one of the important components of floor scrubbers. Their main function is to provide support for the floor scrubber, making it easier for operators to push the floor scrubber to move and clean the floor. Compared with wheels made of other materials, rubber wheels have the advantages of providing stable friction, reducing noise and vibration, protecting the floor, and extending the life of the equipment. However, rubber wheels also have disadvantages in actual use. Rubber outer rings are prone to aging, hardening, and cracking due to long-term exposure to the sun and rain.
[0003] In order to meet the normal use of the floor scrubber, the aged rubber wheel needs to be replaced. However, the rubber outer ring of the rubber wheel is thicker, and the hook of the conventional puller is too short. If the puller is used to remove the rubber wheel, the hook cannot be hooked on the metal inner ring of the rubber wheel, but can only act on the rubber outer ring of the rubber wheel. Since the rubber is easily deformed under force, the hook of the puller is easy to be unhooked, making it difficult to remove the rubber wheel from the floor scrubber.
[0004] Therefore, the common method of disassembling the rubber wheel is to cut off the rubber ring of the rubber wheel with a knife, and then use the puller hook to hook the metal inner ring of the rubber wheel to remove the wheel. However, there are many floor scrubbers in the workshop, and the rubber outer ring and the metal inner ring of the rubber wheel are tightly bonded. The process of cutting off the rubber outer ring piece by piece with a knife takes a long time, has low work efficiency, and affects the replacement progress. In addition, in the process of cutting off the rubber outer ring of the rubber wheel with a knife, the operator is at risk of being scratched, which poses a great safety hazard. Utility Model Content

[0032] refer to Figure 1 and Figure 2 An embodiment of the present disclosure provides a rubber wheel disassembly tool for removing a rubber wheel from a wheel axle 6 , wherein the rubber wheel is composed of an inner ring 51 and a rubber outer ring 52 which is sleeved on the outer periphery of the inner ring 51 .
[0033] The rubber wheel disassembly tool includes a push rod 1, a cross rod 2 and two hook arms 3. The push rod 1 has a threaded section 11, and the first end of the push rod 1 is configured to abut against the end of the wheel axle 6. The cross rod 2 includes a matching seat 21 and two rod bodies 22, the threaded section 11 passes through the matching seat 21 and is threadedly matched with the matching seat 21, and one end of the two rod bodies 22 is connected to the outer periphery of the matching seat 21. The two hook arms 3 are arranged corresponding to the two rod bodies 22, each hook arm 3 includes an arm body 31 and a pull hook 32, the hook arm 3 is connected to the corresponding rod body 22 through the arm body 31, and the pull hook 32 is arranged at one end of the arm body 31 away from the rod body 22 and extends in a direction close to the axis of the push rod 1, so that the pull hook 32 can hook the axial side of the inner ring 51 away from the cross rod 2.
[0034] Optionally, the inner ring 51 is made of metal material. Optionally, the two rod bodies 22 are coaxially arranged. Optionally, the hook 32 extends along the radial direction of the push rod 1.
[0035] The working process of the rubber wheel removal tool provided by the embodiment of the present disclosure is as follows.
[0036] One end of the wheel axle 6 is usually provided with a threaded fastener to limit the axial movement of the rubber wheel along the wheel axle 6. Before disassembling the rubber wheel, the threaded fastener is removed from the wheel axle 6.
[0037] The first end of the push rod 1 is pressed against the end of the wheel shaft 6, and the hook 32 of the hook arm 3 is extended to the side of the inner ring 51 axially away from the cross bar 2. The push rod 1 is rotated relative to the matching seat 21 around its own axis, and the cross bar 2 gradually moves away from the first end of the push rod 1 along the axial direction of the push rod 1 until the hook 32 can hook the inner ring 51.
[0038] The push rod 1 continues to rotate around its own axis relative to the matching seat 21, and the cross bar 2 continues to move away from the first end of the push rod 1 along the axial direction of the push rod 1, and drives the hook 32 to apply a pulling force to the inner ring 51, so that the rubber wheel gradually moves away from the end of the axle 6 along the axial direction of the axle 6 until the rubber wheel is removed from the axle 6.
[0039] The rubber wheel removal tool provided in the embodiment of the present disclosure can act on the inner ring of the rubber wheel. By using the rubber wheel removal tool, the operator does not need to cut off the rubber outer ring of the rubber wheel with a knife, and can remove the rubber wheel from the wheel axle as a whole. Therefore, the removal efficiency of the rubber wheel of the floor scrubber can be improved, thereby improving the replacement progress of the rubber wheels of multiple floor scrubbers in the workshop, and can avoid the risk of scratches on the operator, thereby reducing the safety hazards in the process of removing the rubber wheel.
[0040] With reference to the above working process, the rubber wheel disassembly tool provided in the embodiment of the present disclosure can not only disassemble the rubber wheel of the floor scrubber, but also disassemble the bearings, gears and other similar structures.
[0041] In some embodiments, the hook 32 has a supporting surface 320 , and the hook 32 is configured to hook the inner ring 51 by supporting the inner ring 51 through the supporting surface 320 when the push rod 1 is against the inner ring 51 . The supporting surface 320 is a plane facing the rod body 22 .
[0042] By providing the abutting surface 320 , the contact between the hook 32 and the inner ring 51 is in a surface-to-surface contact, so that the inner ring 51 can be hooked more stably.
[0043] In some embodiments, the hook 32 is in an elongated strip shape, and the abutting surface 320 is a side surface of the hook 32 .
[0044] Optionally, the cross section of the hook 32 perpendicular to its length direction is rectangular.
[0045] In some embodiments, the arm body 31 of each hook arm 3 is rotatably connected to the corresponding rod body 22 around the axis of the corresponding rod body 22 .
[0046] Taking into account the space between the rubber wheel and the body of the floor scrubber, that is, the relatively narrow operating space required for the hook 32 to hook the inner ring 51, when using the rubber wheel removal tool of the above embodiment to remove the rubber wheel, the arm body 31 of at least one hook arm 3 can be first rotated around the axis of the rod body 22 to a position away from the rubber wheel, and after the first end of the push rod 1 is pressed against the end of the wheel axle 6, the arm body 31 is rotated around the axis of the rod body 22 to the gap between the body and the rubber wheel of the floor scrubber, and then the push rod 1 is rotated, and the relative positions of the push rod 1 and the cross bar 2 are adjusted so that the hook 32 hooks the inner ring 51 of the rubber wheel to remove the rubber wheel.
[0047] The rubber wheel removal tool of the above embodiment can avoid structural interference between the rubber wheel and the vehicle body during the removal process by providing a movable hook arm, thereby improving the convenience of the removal operation and facilitating the rapid removal of the rubber wheel.
[0048] In some embodiments, the arm body 31 is provided with a through hole, and the rod body 22 passes through the through hole and forms a shaft-hole matching structure with the arm body 31 .
[0049] In the above embodiment, considering that the arm body 31 is movably connected to the rod body 22, the matching form of the arm body 31 and the rod body 22 can ensure that the arm body 31 can rotate relative to the rod body 22. During the process of removing the rubber wheel, the hook arm 3 can be stably stressed, so that the hook 32 can stably hook the inner ring 51 of the rubber wheel.
[0050] In some embodiments, the rubber wheel removal tool further includes a limiting portion 4 , which is configured to limit the hook arm 3 from being separated from the rod body 22 .
[0051] In the above embodiment, the limiting portion 4 limits the hook arm 3 from being separated from the rod body 22 during the process of removing the rubber wheel, so that the pull hook 32 can stably hook the inner ring 51 of the rubber wheel.
[0052] In some embodiments, the limiting portion 4 and the hook arm 3 are detachably mounted on the rod body 22 .
[0053] Taking into account the space between the rubber wheel and the body of the floor scrubber, that is, the operating space required for the hook 32 to hook the inner ring 51 is relatively narrow, when using the rubber wheel removal tool of the above embodiment to remove the rubber wheel, at least one limit portion 4 can be removed from the rod body 22 first, and then the corresponding hook arm 3 can be removed from the rod body 22, and the removed hook arm 3 can be extended into the gap between the body and the rubber wheel of the floor scrubber, and then the hook arm 3 can be installed on the rod body 22, and then the top rod 1 is rotated, and the relative positions of the top rod 1 and the cross bar 2 are adjusted so that the hook 32 hooks the inner ring 51 of the rubber wheel to remove the rubber wheel.
[0054] The rubber wheel removal tool of the above embodiment is provided with a detachable hook arm, which can avoid structural interference between the rubber wheel and the vehicle body during the removal process, improve the convenience of the removal operation, and facilitate the rapid removal of the rubber wheel.
[0055] In some embodiments, a screw hole is provided at one end of the rod body 22 away from the mating seat 21 , and the limiting portion 4 includes a bolt, which cooperates with the screw hole to prevent the hook arm 3 from separating from the rod body 22 .
[0056] The limiting part 4 composed of the bolt is detachable. When the bolt is in the screw hole, the head and tail of the bolt can block the hook arm 3 to prevent the hook arm 3 from being separated from the rod body 22. When the bolt is removed from the screw hole, the hook arm 3 can also be removed from the rod body 22. The structure of the bolt and the screw hole is easy to process, has strong versatility, and is low in cost.
[0057] In order to enable the hook 32 to hook the inner ring 51 of the rubber wheel, in some embodiments, the radial dimension of the hook 32 along the push rod 1 is configured to be larger than half of the difference between the outer diameter and the inner diameter of the rubber outer ring 52 .
[0058] For different models of floor scrubbers, the rubber wheels are universal parts. For example, for a common type of rubber wheel, the diameter of the inner ring 51 is 16 cm, the inner diameter of the rubber outer ring 52 is 16 cm, and the outer diameter is 20 cm. Half of the difference between the outer diameter and the inner diameter of the rubber outer ring 52, that is, the thickness of the rubber outer ring 52 is 2 cm.
[0059] In some embodiments, the radial dimension of the hook 32 along the push rod 1 is greater than 2 cm.
[0060] Optionally, the radial dimension of the pull hook 32 along the push rod 1 is 8 cm, and the distance between the end of each rod body 22 of the cross bar 2 away from the matching seat 21 and the axis of the push rod 1 is 15 cm.
[0061] In some embodiments, the position of the hook arm 3 along the axial direction of the corresponding rod body 22 is adjustable.
[0062] Optionally, the hook arm 3 is movably arranged along the axial direction of the corresponding rod body 22. In the above embodiment, when removing the rubber wheel, the position of the hook arm 3 along the axial direction of the corresponding rod body 22 can be adjusted to adjust the distance between the two hook arms 3 along the direction, so that the rubber wheel removal tool can remove rubber wheels of different specifications.
[0063] In some embodiments, the top rod 1 has a hexagonal prism segment 12 , and the hexagonal prism segment 12 is disposed at the second end of the top rod 1 .
[0064] The hexagonal column section 12 is used to match with a common spanner, an adjustable spanner or an inner hexagon socket, for example, the hexagonal column section 12 can match with a No. 10 spanner or an inner hexagon socket. The common spanner, adjustable spanner or inner hexagon socket can apply force to the screw rod through the hexagonal column section 12, so that the top rod 1 rotates around its own axis relative to the cross rod 2.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution for protection requested by the present disclosure.
