[0049] The utility model provides a tool for replacing wheels of a sintering ring cooling machine trolley, specifically as follows Figure 1 As shown, the replacement tool includes a wheel removal device 10 and a lifting device 20, wherein the wheel removal device 10 includes a top seat 11, and the left and right sides of the top seat 11 are respectively provided with a first clamping slot and a second clamping slot that can clamp the wheel 100, and the middle part of the top seat 11 is provided with a top rod 12 for supporting the wheel axle and being able to extend and retract along the axial direction of the wheel axle; the lifting device 20 includes a support frame 21, a boom 22 and a winch 23, wherein the first end of the boom 22 is fixedly connected to the support frame 21, the second end of the boom 22 extends in a horizontal direction, and the winch 23 is rotatably set on the support frame 21, and a steel wire rope 231 is wound on the winch 23, and the first end of the steel wire rope 231 passes around the second end of the boom 22 and extends downward, and a clamp 30 is provided at the first end of the steel wire rope 231.

[0050] The beneficial effect of the tooling for replacing the wheel of the sintering ring cooling machine trolley of the present invention is that, first, when disassembling the wheel, the top seat 11 of the wheel disassembly device 10 is clamped on the wheel 100, that is, the left side of the wheel 100 is clamped by the first clamping groove located on the left side of the top seat 11, and the right side of the wheel 100 is clamped by the second clamping groove located on the right side of the top seat 11, and then the wheel axle is supported by the top rod 12 set in the middle of the top seat 11, so that the top seat 11 can be supported to move away from the wheel axle through the extension of the top rod 12, and the top seat 11 will drive the wheel 100 to move together, and then the wheel 100 can be pulled out from the wheel axle to complete the disassembly of the wheel; therefore, compared with the method of manually knocking the wheel for disassembly in the prior art, the present invention can greatly reduce the labor intensity of disassembling the wheel, and improve the disassembly efficiency, saving time and effort.

[0051] When installing a new wheel, first connect it to the wheel through the clamp 30 set at the first end of the wire rope 231, that is, hold the wheel surface with the clamp 30, and then lift the wheel by rotating the winch 23. When the mounting hole on the wheel is at the same height as the wheel axle, align the mounting hole on the wheel with the wheel axle for installation. Since the utility model is connected to the wheel surface by the clamp and then lifted, it can ensure that the wheel is subjected to balanced force during lifting, and further ensure that the wheel will not be skewed during lifting, making it easier to adjust and install the wheel when installing it on the wheel axle, thereby improving the accuracy and convenience of installation.

[0052] Specifically, such as Figure 1 As shown, in order to ensure the safety of wheel removal, the wheel to be removed can also be connected to the lifting device 20 when removing the wheel, that is, the wheel to be removed can be pre-grasped by the lifting device 20 to prevent the wheel from falling directly to the ground when being removed from the wheel axle, causing safety risks to the construction workers.

[0053] Specifically, such as Figure 1 As shown, a handle 232 is provided on the winch 23. When the winch 23 is rotated, the winch can be rotated by holding the handle 232. In other optional embodiments, a drive motor can be provided on the support frame 21, which is connected to the winch through the drive motor. When working, the winch 23 can be driven by the drive motor to rotate.

[0054] Preferably, Figure 2As shown, in this embodiment, the top seat 11 includes a base plate 111, a first pull rod 112 and a second pull rod 113, and the first pull rod 112 and the second pull rod 113 are fixedly arranged on the left and right sides of the base plate 111 respectively. Specifically, the first pull rod 112 is provided with a first boss 1121 and a second boss 1122 extending in a direction close to the second pull rod 113, and the first boss 1121 and the second boss 1122 are arranged at intervals, and the interval between the first boss 1121 and the second boss 1122 forms the first clamping groove; similarly, the second pull rod 113 is provided with a third boss 1131 and a fourth boss 1132 extending in a direction close to the first pull rod 112, and the third boss 1131 and the fourth boss 1132 are arranged at intervals, and the interval between the third boss 1131 and the fourth boss 1132 forms the second clamping groove; specifically, the top rod 12 is fixedly arranged in the middle of the base plate 111. Specifically, in this embodiment, the push rod 12 is a hydraulic push rod, for example, a hydraulic jack.

[0055] Furthermore, considering that the wheel 100 has a wheel sleeve in its mounting hole, the prior art mainly removes the wheel sleeve by gas cutting, which is time-consuming and labor-intensive. Figure 2 As shown, in this embodiment, a sleeve top plate 120 that matches the wheel sleeve is detachably connected to the push rod 12, that is, the diameter of the sleeve top plate 120 is the same as the outer diameter of the wheel sleeve. After the wheel is removed from the wheel axle, the sleeve top plate 120 is connected to the push rod 12, that is, the piston rod of the hydraulic push rod, and the sleeve top plate 120 is pressed against the wheel sleeve. Then, the wheel sleeve is pushed out of the mounting hole of the wheel by extending the push rod 12. Therefore, compared with the prior art of removing by gas cutting, the dismantling method of the utility model is simple to operate, convenient to dismantle, and highly efficient. Specifically, as Figure 1 As shown, in order to facilitate the installation and removal of the shaft sleeve top plate 120 , a screw is welded and fixed on both the left and right sides of the shaft sleeve top plate 120 .

[0056] Preferably, Figure 3 As shown, in this embodiment, the clamp 30 includes an upper clamp 31 and a lower clamp 32, and the upper clamp 31 and the lower clamp 32 are connected by bolts. With this structural design, the clamp 30 is easy to install and remove when connected to the wheel 100, and the wheel can be effectively clamped and fixed by tightening the bolts. Figure 1 As shown, in this embodiment, a lifting lug 310 is provided on the upper half hoop 31 , and the first end of the steel wire rope 231 is connected to the lifting lug 310 .

[0057] Preferably, Figure 1As shown, in this embodiment, the support frame 21 includes a base 211 and a support column 212 fixedly disposed on the base 211. The first end of the lifting arm 22 is fixedly connected to the support column 212. Specifically, a roller 2110 is provided at the bottom of the base 211. By providing the roller 2110 on the base 211, the lifting device 20 can be moved and relocated as needed, which is convenient for use.

[0058] Preferably, in order to enhance the stability of the support frame 21, Figure 1 As shown, a reinforcing rib plate 213 is fixed between the base 211 and the support column 212. Further, in order to improve the stability of the lifting device 20 when lifting the wheel, as shown in FIG. Figure 1 As shown, a counterweight 40 is further provided on the support frame 21 .

[0059] Preferably, to improve the safety of the lifting device 20 when lifting the wheel 100, in this embodiment, a self-locking mechanism is provided on the lifting device 20. The self-locking mechanism is used to limit the loosening of the wire rope toward the first end of the wire rope. The provision of the self-locking mechanism can prevent the lifting device 20 from suddenly falling downward when lifting the wheel, thereby improving the safety of the operation.

[0060] Specifically, in some embodiments, the self-locking mechanism may be a wire rope self-locking device. Since the wire rope self-locking device is a conventional structure in the prior art, for example, it may be a wire rope self-locking device disclosed in Patent No. ZL202321539158.7, so it will not be described in detail here.

[0061] Specifically, in some embodiments, the self-locking mechanism can be a ratchet mechanism, that is, the ratchet mechanism includes a ratchet provided on the winch 23 and a pawl provided on the support column 212 and cooperating with the ratchet. The cooperation between the ratchet and the pawl can only make the winch rotate in a single direction clockwise. When the winch rotates clockwise, it winds the wire rope 23 to lift the first end of the wire rope 231. The cooperation between the ratchet and the pawl can limit the counterclockwise rotation of the winch, thereby limiting the first end of the wire rope 231 from pulling the winch downward to unwind, thereby preventing the first end of the wire rope from suddenly falling downward when lifting the wheel. When the winch needs to rotate counterclockwise, the pawl can be manually opened relative to the ratchet.

[0062] In summary, the tooling for replacing the wheels of the sintering ring cooler trolley of the present invention can greatly reduce the labor intensity of wheel disassembly, improve disassembly efficiency, and save time and effort. Through the lifting device of the present invention, there is no need to rely on a hand winch, and the wheel will not be tilted or lifted when it is lifted for installation, which improves the accuracy and convenience of installation. The number of people required for the operation can be reduced from 10 to the current 4, and the time required to replace a trolley wheel is reduced from 3 hours to 1 hour, which greatly reduces labor costs and time costs. Therefore, the present invention effectively overcomes the various shortcomings of the existing technology and has a high industrial utilization value.

[0063] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
