Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a quick disassembly device for a support roller grinding wheel. Background Technology

[0002] Currently, the support roller grinding wheels in support roller grinding machines are large in size and heavy in weight. When disassembling them, the operator needs to use a lifting tool to lift the grinding wheel and then disassemble it by pulling it outward or using a pry bar.

[0003] This method of disassembling the grinding wheel is quite laborious, increasing the workload of the operator. Moreover, it poses a significant safety risk during operation, as the grinding wheel may fall off and injure people or damage equipment. Utility Model Content

[0004] To address the technical problems of the laborious and dangerous grinding wheel disassembly process in existing technologies, which increases the workload of operators and poses significant safety risks such as grinding wheel detachment causing injury or equipment damage, this utility model provides a quick disassembly device for grinding wheels on support roller grinding machines.

[0005] The present invention provides a quick-release device for the grinding wheel of a support roller grinding machine, which adopts the following technical solution: A quick-release device for a grinding wheel on a support roller grinding machine includes a boom; it also includes a lifting lug fixedly installed on the top of the boom, the lifting lug being connected to a lifting device; a disassembly mechanism for disassembling the grinding wheel is provided at the bottom of the boom; and a reinforcing mechanism for supporting the grinding wheel upwards is provided at the bottom of the disassembly mechanism.

[0006] By adopting the above technical solution: when disassembling the grinding wheel, the lifting equipment lifts the boom through the lifting lugs, which reduces the friction between the bottom of the grinding wheel and the spindle. The grinding wheel is disassembled by connecting the disassembly mechanism to the grinding wheel. The bottom of the grinding wheel is supported upward by the reinforcing mechanism, which reduces the pressure of the grinding wheel on the disassembly mechanism and prevents the grinding wheel from falling off the disassembly mechanism during the disassembly process.

[0007] Furthermore, the boom is an L-shaped structure welded from I-beams.

[0008] By adopting the above technical solution, the crane arm provides support and force transmission for the entire device, possessing sufficient strength and rigidity to ensure that no deformation occurs during the lifting process. Furthermore, the disassembly mechanism includes two fixed beams symmetrically welded to both sides of the bottom of the boom; an arc-shaped beam disposed at the end of the fixed beam; an installation hole is provided at the end of the two fixed beams away from the boom, and a fixing screw is slidably disposed in the installation hole; it also includes a long screw with a central hole provided at the center position of the bottom of the boom, and the long screw is screwed into the central hole.

[0009] By adopting the above technical solution: the stability of the device is increased by the arc beam, and the fixing screw is locked in the screw hole of the grinding wheel flange after passing through the mounting hole, so that the device is fixedly connected to the grinding wheel. By rotating the long screw into the center hole, the long screw presses against the spindle at the center of the grinding wheel. As the long screw is continuously screwed in, the ejection force gradually increases, and finally the grinding wheel is ejected from the spindle, thus completing the quick disassembly of the grinding wheel.

[0010] Furthermore, one end of the arc-shaped beam is welded and fixed to the end of the fixed beam, and the other end is welded and fixed to the side of the boom.

[0011] By adopting the above technical solution, the curved beam is fixedly connected to the fixed beam and the boom, thereby increasing the stability of the device during use.

[0012] Furthermore, the reinforcing mechanism includes an extension arm disposed at the bottom of the fixed beam. The top of the extension arm has a limiting plate, and a connecting hole is provided at the upper part of the fixed beam. The extension arm extends downward after passing through the connecting hole. The limiting plate at the upper part of the extension arm stops the downward extension position of the extension arm at the upper part of the connecting hole.

[0013] By adopting the above technical solution, the limiting plate stops at the top of the connecting hole, and the extension arm is hoisted at the bottom of the fixed beam.

[0014] Furthermore, it also includes a support block that is slidably set at the bottom of the extension arm to support the grinding wheel upwards.

[0015] By adopting the above technical solution, the grinding wheel is supported upward by the support block.

[0016] Furthermore, the extension arm has a slide rail at its bottom, and a connecting plate is located at one end of the slide rail away from the extension arm. The support block is slidably connected to the slide rail. One end of the support block extends outward after passing through the bottom sidewall of the extension arm, and a spring is connected between the other end of the support block and the connecting plate.

[0017] By adopting the above technical solution: during the disassembly of the grinding wheel, the support block moves to the bottom of the grinding wheel under the elastic force of the spring, providing upward support for the grinding wheel.

[0018] Furthermore, it also includes a limiting shaft at the end of the support block. The limiting shaft passes through the connecting plate and has a baffle at its end. The spring is sleeved on the outside of the limiting shaft, and the baffle at the end of the limiting shaft stops against the outer wall of the connecting plate.

[0019] By adopting the above technical solution: the baffle at the end of the limiting shaft stops the movement of the support block by blocking the outer wall of the connecting plate, thus limiting the maximum distance of movement of the support block and preventing the support block from sliding off the slide rail. Furthermore, the sliding position of the support block can be adjusted by pulling the baffle.

[0020] In summary, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a lifting arm, lifting lugs, and a disassembly mechanism, allows for the rapid disassembly of the grinding wheel. First, the lifting equipment is connected to the lifting lugs. The fixing screws are then inserted into the mounting holes and tightened into the threaded holes on the grinding wheel flange, ensuring a secure connection between the device and the grinding wheel. Next, the lifting equipment is activated, and the lifting arm is used to lift the grinding wheel upwards, reducing the friction between the bottom of the grinding wheel and the spindle. Then, a long screw is passed through the center hole and pressed against the spindle at the center of the grinding wheel. As the long screw is continuously screwed in, the ejection force gradually increases, eventually pushing the entire grinding wheel off the spindle, completing the rapid disassembly of the grinding wheel. This device, through its mechanical structure design, achieves rapid, labor-saving, and safe disassembly of the grinding wheel on a roller grinder, reducing the operator's workload. Furthermore, the grinding wheel is less likely to detach from the device during disassembly, minimizing safety risks.

[0021] 2. By setting up a reinforcing mechanism, when disassembling the grinding wheel, the baffle is pulled outward to move the support block in the reinforcing mechanism to the side wall of the extension arm, preventing the support block from interfering with other parts of the grinding machine during the installation of this device. Then, the device is installed on the grinding wheel flange. Finally, the baffle is released, allowing the support block to move to the bottom of the grinding wheel under the elastic force of the spring to support the grinding wheel upward. This structural design reduces the pressure of the grinding wheel on the fixing screws, preventing the fixing screws from breaking due to excessive force during the disassembly of the grinding wheel, thus preventing the grinding wheel from falling off and posing a safety hazard.

Detailed Implementation

[0024] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0025] The first embodiment of this utility model, referred to... Figure 1 As shown, a quick disassembly device for a support roller grinding machine grinding wheel is disclosed, including a lifting arm 1, which is an L-shaped structure welded from I-beams. The lifting arm 1 provides support and force transmission for the entire device, and has sufficient strength and rigidity to ensure that it will not deform during the lifting process. A lifting lug 2 is fixedly installed on the top of the lifting arm 1. The lifting lug 2 is made of high-strength alloy steel and is connected to a lifting device, which lifts the lifting arm 1 through the lifting lug 2. A disassembly mechanism 3 is provided at the bottom of the lifting arm 1, which is connected to the grinding wheel to disassemble the grinding wheel.

[0026] Specifically, refer to Figure 1 and Figure 2 As shown, the disassembly mechanism 3 includes two fixed beams 31 symmetrically welded to both sides of the bottom of the boom 1. One end of each fixed beam 31, away from the boom 1, has a mounting hole 311. A fixing screw 33 is slidably disposed within the mounting hole 311. When disassembling the grinding wheel, the fixing screw 33 passes through the mounting hole 311 and locks into the screw hole of the grinding wheel flange, thus fixing the device to the grinding wheel. An arc-shaped beam 32 is provided at the end of the fixed beam 31. One end of the arc-shaped beam 32 is welded to the end of the fixed beam 31, and the other end is welded to the side of the boom 1. The arc-shaped beam 32 increases the stability of the device during lifting. It also includes a long screw 34, with a central hole 11 at the center of the bottom of the boom 1. The long screw 34 is screwed into the central hole 11. In use, by rotating the long screw 34 into the central hole 11, the long screw 34 presses against the spindle at the center of the grinding wheel. As the long screw 34 is continuously screwed in, the ejection force gradually increases, eventually ejecting the entire grinding wheel from the spindle, thus completing the quick disassembly of the grinding wheel.

[0027] When disassembling the grinding wheel, first connect the lifting equipment to the lifting lug 2, insert the fixing screw 33 into the mounting hole 311 and tighten it into the threaded hole on the grinding wheel flange to securely connect the device to the grinding wheel. Next, start the lifting equipment and lift the lifting arm 1 through the lifting lug 2 to raise the grinding wheel upwards, reducing the friction between the bottom of the grinding wheel and the spindle. Then, pass the long screw 34 through the center hole 11 and press it against the spindle at the center of the grinding wheel. As the long screw 34 is continuously screwed in, the ejection force gradually increases, eventually pushing the entire grinding wheel off the spindle, completing the rapid disassembly of the grinding wheel. This device, through its mechanical structure design, achieves rapid, labor-saving, and safe disassembly of the grinding wheel on the support roller grinding machine, reducing the labor intensity of operators. Furthermore, the grinding wheel is less likely to fall out of the device during disassembly, reducing safety risks during the process.

[0028] To increase the robustness of this device during use, a second embodiment is proposed, as described above. Figure 1 As shown, a reinforcing mechanism 4 is provided at the bottom of the disassembly mechanism 3. When disassembling the grinding wheel, the reinforcing mechanism 4 provides upward support to the bottom of the grinding wheel, reducing the pressure of the grinding wheel on the fixing screw 33 in the disassembly mechanism 3. This prevents the grinding wheel from breaking due to excessive force on the fixing screw 33 during disassembly, thus avoiding the safety hazard of the grinding wheel falling off.

[0029] Specifically, refer to Figures 3-5 As shown, the reinforcing mechanism 4 includes an extension arm 41 disposed at the bottom of the fixed beam 31. Preferably, the extension arm 41 has a limiting plate 413 at its top and a connecting hole 312 at the upper part of the fixed beam 31. The extension arm 41 extends downward after passing through the connecting hole 312. The limiting plate 413 at the upper part of the extension arm 41 stops at the upper part of the connecting hole 312 to limit the downward extension position of the extension arm 41. A support block 42 is slidably disposed at the bottom of the extension arm 41 to support the grinding wheel upward. Preferably, the bottom of the extension arm 41 has a slide rail 411, and the end of the slide rail 411 away from the extension arm 41 has a connecting plate 412. The support block 42 is slidably connected to the slide rail 411. One end of the support block 42 extends outward after passing through the bottom side wall of the extension arm 41, and a spring 44 is connected between the other end of the support block 42 and the connecting plate 412. During the disassembly of the grinding wheel, the support block 42 moves to the bottom of the grinding wheel under the elastic force of the spring 44 to support the grinding wheel upward. A limiting shaft 421 is provided at the end of the support block 42. After passing through the connecting plate 412, a baffle 423 is provided at its end. The spring 44 is sleeved on the outside of the limiting shaft 421. The baffle 423 at the end of the limiting shaft 421 stops the movement of the support block 42 by stopping it against the outer wall of the connecting plate 412, thereby limiting the maximum distance of movement of the support block 42 and preventing the support block 42 from sliding off the slide rail 411. The sliding position of the support block 42 can be adjusted by pulling the baffle 423.

[0030] When disassembling the grinding wheel, pull the baffle 423 outward to move the support block 42 to the side wall of the extension arm 41 to prevent the support block 42 from interfering with other parts of the grinding machine during the installation of this device. Then, install this device on the grinding wheel flange. Finally, release the baffle 423 so that the support block 42 moves to the bottom of the grinding wheel under the elastic force of the spring 44 to support the grinding wheel upward. This structural design reduces the pressure of the grinding wheel on the fixing screw 33 and prevents the fixing screw 33 from breaking due to excessive force during the disassembly of the grinding wheel, which could cause the grinding wheel to fall off.
