Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering auxiliary tools, specifically a device for disassembling a wheel hub, flange, and wheel as a whole. Background Technology

[0002] In the maintenance and repair of heavy-duty trucks and engineering vehicles, disassembling the wheel hubs, tires, and flanges is a common and necessary operation. However, in practice, due to corrosion and other reasons between the axle and the wheel hub flange assembly, the axle and wheel hub flange assembly often become stuck after the wheel hub bolts are removed, making them difficult to separate. This phenomenon is particularly prominent in large vehicles, mainly due to component deformation caused by long-term high-load operation, insufficient lubrication, or corrosion, as well as the possibility that the axle and wheel hub flange assembly may partially use an interference fit design.

[0003] Traditional disassembly methods typically rely on manual operation or simple mechanical tools. Due to the large weight of the assembly and the situation where the axle and wheel hub flange assembly are stuck together, existing technologies usually use pry bars and hammers to disassemble it, which is a relatively primitive method. There are also specific tooling tools used for disassembly, such as the non-destructive disassembly tool for automobile wheel rims with patent number CN222903888U. The tooling tool uses an internal gear ring to rotate on one side of a fixed plate, which in turn drives the first gear to rotate on the outer surface of the shaft. At the same time, the gear plate drives the movable rod to slide inside the fixed part, thereby causing the chisel head to slowly move towards the connection between the wheel rim assembly flange and the wheel hub flange. By applying pressure, the wheel rim assembly is separated, avoiding vibration that could damage internal parts during disassembly. For example, a tool for removing brake wheel hubs from dump trucks, patent number CN222329377U, uses a movable base frame to fit against the outside of the wheel hub to be removed, and a hook claw rod to limit the movement of the wheel hub. When the reaction frame with hydraulic jack extends, the wheel hub, which is restrained by the wheel ring, moves outward under the pull of the hook claw rod to limit the movement of the wheel hub, thereby achieving the function of removing the wheel hub. This not only saves manpower and reduces labor intensity, but also ensures production safety.

[0004] However, in the existing technology, although the above two disassembly methods using specific tooling can save the operator's labor intensity when separating the axle and the wheel hub flange assembly to a certain extent, they cannot directly support the wheel, wheel hub flange assembly, wheel hub and other parts when they are removed from the vehicle body, nor can they directly separate the wheel hub flange assembly from the axle when the wheel hub flange assembly is stuck to the axle, which is time-consuming and labor-intensive.

[0005] Therefore, the challenge of safely and efficiently separating the axle from the wheel hub flange assembly while smoothly removing components such as wheels, flanges, and hubs has greatly troubled maintenance personnel. This not only increases the difficulty and labor intensity of operation, but may also lead to damage to the axle or wheel hub flange assembly due to improper operation, or even cause personal safety accidents.

[0006] To address this, a device for the overall disassembly of the hub, flange, and wheel is proposed. Summary of the Invention

[0007] The purpose of this utility model is to provide a device for disassembling a wheel hub, flange, and wheel as a whole. This device addresses the problems in the prior art where the heavy weight of the wheel hub flange assembly makes disassembly difficult, and where the assembly sticks to the axle, increasing the difficulty of disassembly and increasing the risk of damage to parts due to improper operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A device for disassembling a hub, flange, and wheel as a whole includes a hydraulic forklift, a receiving frame, an ejector frame, an ejector cylinder, a stabilizing rope, and an adjusting component. The receiving frame and the ejector frame are slidably connected to the hydraulic forklift from left to right. The receiving frame and the ejector frame are fixedly connected. The ejector cylinder is connected to the ejector frame through the adjusting component, which is used to adjust the height of the ejector cylinder. The stabilizing rope is fixedly connected to the ejector cylinder.

[0010] Preferably, the receiving frame and the ejector frame are provided with threaded holes on their sides, and the receiving frame and the ejector frame are detachably connected to the hydraulic forklift through the engagement of the threaded holes and bolts.

[0011] The purpose of the above design is to provide threaded holes on both sides of the receiving frame and the ejector frame so that when the tire needs to be removed, the receiving frame and the ejector frame can simply be placed on the hydraulic forklift and then bolted to the hydraulic forklift. When the receiving frame and the ejector frame need to be disassembled and used separately on the hydraulic forklift, the receiving frame and the ejector frame can be removed from the hydraulic forklift simply by loosening them.

[0012] Preferably, the adjustment component includes an adjustment frame, an adjustment column, an adjustment slot, and an adjustment pin. The adjustment frame is fixedly connected to the center of the upper end of the ejector frame. The adjustment column is slidably connected to the adjustment frame. The ejector cylinder is fixedly connected to the upper end of the adjustment column. Multiple adjustment slots are provided, and the multiple adjustment slots are longitudinally distributed on the side of the adjustment column. The adjustment pin is connected to the side wall of the adjustment frame, and the adjustment pin cooperates with the adjustment slot.

[0013] In the above scheme, when it is necessary to adjust the height of the ejector cylinder so that the telescopic shaft of the ejector cylinder is aligned with the axle at the center of the wheel, it is only necessary to pull out the adjusting pin, so that the adjusting pin is pulled out of the adjusting slot, and then drive the adjusting column to slide on the adjusting frame, so as to adjust the position and height of the ejector cylinder on the adjusting column.

[0014] Preferably, the upper center of the receiving frame is provided with a centering groove, which is used to keep the center of the wheel aligned with the ejector frame when the wheel is placed on the receiving frame.

[0015] In the above scheme, the purpose of the centering groove design is that when the wheel is removed from the vehicle and placed on the receiving frame, the centering groove in the center of the receiving frame can fix the wheel in the center of the receiving frame. This makes it possible to separate the wheel hub flange assembly from the axle using the ejector cylinder, which only requires adjusting the position of the ejector cylinder, reducing the difficulty of the operator's work and improving work efficiency.

[0016] Preferably, the stabilizing ropes are provided in two sets, and the two sets of stabilizing ropes are symmetrically arranged on the front and rear sides of the ejector cylinder.

[0017] In the above scheme, the stabilizing rope can further stabilize the wheel, so that when the ejector cylinder separates the hub flange assembly from the axle, the stabilizing rope can provide a reaction force to the hub flange assembly, so that when the ejector cylinder ejects, it can drive the hub flange assembly and the hydraulic forklift to move relatively away from the axle, so that the hub flange assembly can be smoothly separated from the axle.

[0018] Preferably, the ejector frame is provided with a fixing plate.

[0019] In the above scheme, the fixed plate can be set so that when the hydraulic forklift drives the receiving frame to receive the wheel, the left end of the fixed plate contacts the wheel, and then the hydraulic forklift can be operated to lift it up so that the wheel being removed can be accurately placed into the centering groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This application, by installing a support frame on a hydraulic forklift, makes it faster, more convenient, and less labor-intensive to disassemble or clamp wheels, hubs, and flanges. When the hub flange assembly sticks to the axle, by installing an ejector cylinder, adjusting components, and stabilizing ropes, it is easier and less labor-intensive to separate the hub flange assembly from the axle, and also ensures stability during separation.

[0028] Example

[0029] Please see Figures 1 to 4 A device for disassembling a wheel hub, flange, and wheel as a whole is provided. The device includes a hydraulic forklift 1, a support frame 2, an ejector frame 3, an ejector cylinder 4, a stabilizing rope 6, and an adjusting component 7. The support frame 2 and the ejector frame 3 are slidably connected to the hydraulic forklift 1 from left to right. The support frame 2 and the ejector frame 3 are fixedly connected. The ejector cylinder 4 is connected to the ejector frame 3 through the adjusting component 7. The adjusting component 7 is used to adjust the height of the ejector cylinder 4. The stabilizing rope 6 is fixedly connected to the ejector cylinder 4.

[0030] Specifically, the hub, flange, and wheel of this application are hereinafter referred to as the hub-flange assembly.

[0031] Please see Figure 1 The receiving frame 2 and the ejector frame 3 are provided with threaded holes on their sides. The receiving frame 2 and the ejector frame 3 are detachably connected to the hydraulic forklift 1 through the engagement of the threaded holes and bolts. The purpose of this design is that, by providing threaded holes on both sides of the receiving frame 2 and the ejector frame 3, when it is necessary to remove the tire, simply place the receiving frame 2 and the ejector frame 3 on the hydraulic forklift 1, and then tighten the receiving frame 2 and the ejector frame 3 to the hydraulic forklift 1 with bolts; when it is necessary to remove the receiving frame 2 and the ejector frame 3 to use the hydraulic forklift 1 alone, simply loosen the bolts at the receiving frame 2 and the ejector frame 3, and the receiving frame 2 and the ejector frame 3 can be removed from the hydraulic forklift 1 by the operator.

[0032] Please see Figure 2 The adjustment component 7 includes an adjustment frame 71, an adjustment column 72, an adjustment slot 73, and an adjustment pin 74. The adjustment frame 71 is fixedly connected to the center of the upper end of the ejector frame 3. The adjustment column 72 is slidably connected to the adjustment frame 71. The ejector cylinder 4 is fixedly connected to the upper end of the adjustment column 72. When working, the ejector cylinder 4 can be extended and retracted by the operator, so that the ejector cylinder 4 can separate the wheel hub flange assembly from the axle. The ejector cylinder 4 can be an Airtac cylinder, or it can be replaced with a retractable hydraulic cylinder, as long as it can achieve control of extension and retraction. Multiple adjustment slots 73 are provided, longitudinally distributed on the side of the adjustment column 72. Adjustment pins 74 are connected to the side wall of the adjustment frame 71. The adjustment pins 74 engage with the adjustment slots 73. This engagement means that when it is necessary to adjust the height of the ejector cylinder 4 so that its telescopic shaft is aligned with the axle head at the center of the wheel hub flange assembly, simply pull out the adjustment pin 74, causing it to exit the adjustment slot 73. This then allows the adjustment column 72 to slide on the adjustment frame 71, thus adjusting the position and height of the ejector cylinder 4 on the adjustment column 72. Once the ejector cylinder 4 is aligned with the center of the wheel hub flange assembly, simply reinsert the adjustment pin 74 into the corresponding adjustment slot 73. For a more stable connection between the adjustment pin 74 and the adjustment frame 71, the adjustment pin 74 can be threaded into and out of the adjustment frame 71 via a connecting post.

[0033] Please see Figure 2 The upper center of the receiving frame 2 is provided with a centering groove 5. The purpose of the centering groove 5 is to fix the hub flange assembly in the center of the receiving frame 2 when the hydraulic forklift 1 lifts the receiving frame 2. This makes it easier to separate the hub flange assembly from the axle using the ejector cylinder 4. This reduces the difficulty of the operator's work and improves work efficiency.

[0034] Please see Figure 2The adjusting frame 71 is fixed with stabilizing ropes 6 on both the front and rear sides. There are two sets of stabilizing ropes 6, which are symmetrically arranged on the front and rear sides of the ejector cylinder 4. The principle of the stabilizing ropes 6 is similar to that of a measuring tape. For specific measuring tape models, please refer to Delixi household measuring tapes for easier understanding. A hook is provided at the end of the stabilizing rope 6 near the fixing plate 31. When it is necessary to use the ejector cylinder 4 to separate the wheel hub flange assembly from the axle, the operator can first pull the hook so that the hook is hooked on the wheel hub hole of the wheel hub flange assembly. After hooking, the stabilizing rope 6 connected to the hook will naturally tighten. Then the operator can fix and lock the stabilizing rope 6, so that the hook can no longer move closer to or away from the adjusting frame 71. Thus, when the ejector cylinder 4 is working, after the extended end of the ejector cylinder 4 contacts the axle, when the ejector cylinder 4 continues to extend, it can drive the wheel hub flange assembly to move away from the axle under the fixation of the stabilizing rope 6, thereby realizing the separation of the wheel hub flange assembly from the axle.

[0035] Working principle: When disassembling the wheel hub flange assembly of a heavy truck or engineering vehicle, the operator first lifts the part to be disassembled with a jack, then moves the hydraulic forklift 1 to below the wheel hub flange assembly to be disassembled, so that the receiving frame 2 on the hydraulic forklift 1 moves to below the wheel hub flange assembly. The left end of the fixing plate 31 on the receiving plate is in contact with the right end of the wheel hub flange assembly. Then the operator controls the hydraulic forklift 1 to lift, so that the hydraulic forklift 1 drives the receiving frame 2 and the ejector frame 3 to lift, so that the centering groove 5 of the receiving frame 2 is in contact with the wheel hub flange assembly and supports the wheel hub flange assembly. Then the hydraulic forklift 1 is pulled, so that the hydraulic forklift 1 drives the receiving frame 2 to pull out the supported wheel hub flange assembly, thus realizing the disassembly of the wheel hub flange assembly.

[0036] When removing the wheel hub flange assembly from the vehicle, if the assembly sticks to the axle and cannot be directly removed, the operator only needs to adjust the position of the ejector cylinder 4 so that it is aligned with the center of the wheel hub flange assembly on the axle. To adjust the position of the ejector cylinder 4, simply pull out the adjusting pin 74, causing it to move out of the adjusting slot 73. Then, the adjusting column 72 will slide on the adjusting bracket 71, thus adjusting the height of the ejector cylinder 4 on the adjusting column 72. After adjusting the ejector cylinder 4 to be aligned with the axle, simply reinsert the adjusting pin 74 into the corresponding adjusting slot 73. After adjusting the position of the ejector cylinder 4, to make the separation of the wheel hub flange assembly safer and more stable, the operator only needs to hook the hook onto the hole in the wheel hub, then keep the stabilizing rope 6 taut and lock it, and finally control the ejector cylinder 4 to work, so that the telescopic shaft of the ejector cylinder 4 extends and approaches the axle at the center of the wheel hub flange assembly, until the ejector cylinder 4 moves away from the axle under the reaction force of the axle. This causes the hydraulic forklift 1 to move the wheel hub flange assembly away from the axle together with the stabilizing rope 6, thereby achieving the separation of the wheel hub flange assembly from the axle, making the separation of the wheel hub flange assembly from the axle more labor-saving, safe and stable.

[0037] After detaching the hub flange assembly from the axle, the operator controls the telescopic shaft of the ejector cylinder 4 to retract and reset. Then, simply unlocking the securing rope 6 and removing the hook from the hole in the hub allows the hub flange assembly to be removed from the support frame 2. When the hydraulic forklift 1 needs to be used independently, the operator simply loosens the bolts at the support frame 2 and the ejector frame 3, loosening the support frame 2 and the ejector frame 3 from the hydraulic forklift 1, allowing the support frame 2 and the ejector frame 3 to be removed from the hydraulic forklift 1, thus enabling the hydraulic forklift 1 to be used independently.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
