Description

Technical Field

[0001] The utility model relates to the technical field of hinge clamp repair tools, in particular to a hinge clamp wheel rim and wheel core disassembly tool. Background Art

[0002] The three bridges and six wheel sides of the articulated truck are the final components for power output to achieve movement and braking. The wheel moves by rotating on the two large and small bearings of the wheel core, and brakes are achieved by the wheel side piston pushing the brake pad, so it is a wearing part. Once the debris of the brake pad falls off partially and is mixed in the wheel core bearing, it will cause the bearing to wear more severely, the service life to be shortened, and the wheel core to leak oil. The wheel core and wheel side need to be disassembled to check, clean, replace the bearings or process the bearing positions to restore them to use. At this stage, the wheel side and wheel core need to be disassembled to move the wheel side to the disassembly frame. The disassembly frame is made of Q355 steel plate with a 40mm thick base, two 16mm thick side plates supporting the wheel side shell, two 1m long solid pipes that overhead and fix the wheel side shell, and a support frame that supports the jack at the top. When the wheel After the wheel rim is lifted off, it is necessary to separate the wheel rim from the wheel core by squeezing the jack and the upper fixing frame. During this process, through analysis of the splitting time, since the splitting frame is fixed at the designated work location and cannot be moved, the time for forward and backward transportation accounts for a large proportion, and the staff are also required to lift and raise the wheel rim, which is not only a physical labor, but also requires a high degree of coordination and skills. Especially at the vehicle maintenance site, the operating space may be limited, making the lifting operation more complicated and time-consuming, increasing the maintenance cost and extending the repair time.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-6 The present invention provides an embodiment of a tool for disassembling the wheel core of an articulated wheel, comprising a base plate 1 and a hydraulic jack 2 mounted on the top of the base plate 1, wherein a support 3 is mounted on the top of the piston rod of the hydraulic jack 2, a cross-angle frame 6 is detachably mounted on the top of the support 3, four arc-shaped hook plate claws 7 extending vertically downward are slidably mounted on the top of the cross-angle frame 6 at equal intervals, the arc-shaped hook plate claws 7 are used to hook with the lower end of the articulated wheel side shell, and a screw rod diameter adjustment structure 8 for controlling the horizontal position of the arc-shaped hook plate claws 7 is mounted on the outer wall of the cross-angle frame 6;

[0020] When the arc-shaped hook plate claws 7 hook the wheel side shell, the multiple arc-shaped hook plate claws 7 can stably connect the wheel side shell, reducing the shaking and instability of the wheel side shell during the separation process;

[0021] Hydraulic jacks 2 generally have a high load capacity and stability, which enables them to safely bear the weight of the vehicle's wheel hub shell while maintaining stability during operation and being less likely to deflect or lose control;

[0022] An external threaded head 4 is fixed to the top of the support 3, and an internal threaded disc 5 for threaded cooperation with the external threaded head 4 is integrally formed at the center of the cross-angle frame 6. The cross-angle frame 6 can be threadedly installed and disassembled through the internal threaded disc 5 and the external threaded head 4, thereby realizing the rapid assembly function of the tool, which is convenient for staff to assemble and use on site in the workshop;

[0023] The cross-angle frame 6 includes four support arms 601 integrally formed at equal intervals on the outer wall of the internally threaded disk 5. The support arms 601 are provided with rectangular slide grooves 602 for the horizontal sliding of the arc-shaped hook plate claw 7. Rectangular anti-slip edges 701 are fixed on both sides of the surface of the arc-shaped hook plate claw 7. The distance between the two rectangular anti-slip edges 701 is equal to the thickness of the cross-angle frame 6.

[0024] The screw diameter adjustment structure 8 includes a C-shaped shaft bracket 801 fixed to the outer wall of one side of the support arm 601, a one-way screw 802 rotatably mounted inside the C-shaped shaft bracket 801, and a nut pair 804 installed at a threaded portion on one end of the one-way screw 802. The top of the nut pair 804 is fixed with a connecting plate 805 for interconnecting with the outer wall of one side of the arc-shaped hook plate claw 7. A dovetail guide rail 803 is fixed to the inner wall of one side of the C-shaped shaft bracket 801, and the nut pair 804 slides in cooperation with the dovetail guide rail 803.

[0025] The staff manually rotates the one-way screw 802 to drive the nut pair 804, the connecting plate 805 and the arc-shaped hook plate claw 7 to slide horizontally. During this process, the rectangular slide groove 602 and the dovetail guide rail 803 guide and support the sliding of the arc-shaped hook plate claw 7 and the nut pair 804, so that the position of the arc-shaped hook plate claw 7 can be quickly adjusted to meet the disassembly operation of wheel side shells and wheel cores with different diameter specifications.

[0026] When the embodiment of the present application is in use, the staff first places the wheel rim shell of the wheel rim and wheel core to be disassembled on the ground, and uses a crane to lift the cross-angle frame 6 in the disassembly tool so that the cross-angle frame 6 is suspended in the center position above the wheel rim shell, and then lowers the cross-angle frame 6, hydraulic jack 2, base plate 1 and other components until the base plate 1 contacts the top center position of the wheel core inside the wheel rim shell. After the initial adjustment of the tool is completed, the staff manually operates each screw diameter adjustment structure 8, and adjusts the position of the arc-shaped hook plate claw 7 on the cross-angle frame 6 through the screw diameter adjustment structure 8 until the hook at the bottom end of the arc-shaped hook plate claw 7 hooks the lower part of the wheel rim shell. When the arc-shaped hook plate claw 7 stably hooks the wheel rim shell, the staff manually pressurizes the hydraulic jack 2 so that the piston rod of the hydraulic jack 2 drives the support 3, the cross-angle frame 6 and the arc-shaped hook plate claw 7. The hook plate claw 7 and other components move upward. At this time, the wheel side shell is subjected to the up and down pulling force of the hydraulic jack 2, the support 3, the arc-shaped hook plate claw 7 and other components, and the wheel core inside the wheel side shell is subjected to the downward thrust of the bottom plate 1 and the hydraulic jack 2, so that the wheel core and the wheel side shell are separated by the pressure jack. In this process, the size of the pressure and the force applied can be precisely controlled according to needs, so as to more effectively separate the wheel side shell and the wheel core. The cross-angle frame 6 and the arc-shaped hook plate claw 7 are hooked to the wheel side shell, so that the hydraulic jack 2 can achieve smoother force transmission during operation, reducing the risk of damage to the wheel side shell or wheel core due to uneven force. At the same time, there is no need to move the wheel side shell to the specified position and perform lifting, positioning and other operations during operation, making the maintenance tool more flexible and convenient at the maintenance site, and improving the efficiency of separating the wheel side and wheel core.
