[0024] The grinding machine clamping device for upward angle operation includes: base 1, lifting mechanism 2, and grinding machine positioning mechanism 3.

[0025] The base 1 is equipped with a lifting mechanism 2 and a handrail 11. During operation, the base 1 provides stable support for the trolley, ensuring that it does not tilt or shake during operation. The operator grips the handrail 11 to perform the grinding operation.

[0026] The lifting mechanism 2 includes a column sleeve 21, a detachable hydraulic jack 22, a lifting column 23, and a lifting control console 223. The column sleeve 21 is mounted on the base 1, and the lifting column 23 is located inside the column sleeve 21. The output end of the cylinder 221 of the detachable hydraulic jack 22 is connected to the bottom end of the lifting column 23. A lifting platform 24 is mounted on the top of the lifting column 23, and a grinding machine positioning mechanism 3 is mounted on the lifting platform. One end of the lifting platform has a hole. The oil pump 222 of the detachable hydraulic jack 22 is placed on the lifting control console 223.

[0027] During operation, the hydraulic jack pump 222 drives the lifting column 23, which cooperates with the column sleeve 21 to adjust the grinding machine positioning mechanism 3 to the required height and fix it in place. The hydraulic jack has powerful performance and stable operation, which can easily drive the lifting mechanism 2 to achieve smooth lifting and lowering of the lifting platform 24, thereby adjusting the height of the lifting platform 24 to meet the grinding operation needs at different heights.

[0028] The grinding machine positioning mechanism 3 includes a grinding machine clamping mechanism 32 and a grinding machine pressing mechanism 31.

[0029] The grinding machine clamping mechanism 32 includes a base plate 321, an arc-shaped pressure plate 322, and a locking structure. One end of the base plate 321 is movably connected to the lifting platform 24, preferably hinged, and the other end is fitted with a stud 311 of the grinding machine clamping mechanism 31. In the grinding machine clamping mechanism 32, the base plate 321 is an obtuse-angled folded plate, consisting of a flat plate and an inclined plate; the end of the inclined plate of the base plate 321 is movably connected to one end of the lifting platform 24, and the end of the flat plate of the base plate 321 is elastically connected to the other end of the lifting platform 24 by the grinding machine clamping mechanism 31.

[0030] The arc-shaped pressure plate 322 has an arc-shaped protrusion that matches the shape of the grinder handle. One end of the arc-shaped pressure plate 322 is movably connected to the base plate 321, preferably hinged, while the other end is detachably connected for opening and locking. A screw 323 and a handle 324 are preferred, similar to the screw 323 and handle 324 structure of a mechanical vise, facilitating operation and ensuring secure locking. One end of a stud 311 is fixed below the flat end of the base plate 321, and a pin 313 is installed at the other end of the stud 311 that protrudes from the lifting platform 24. A spring 312 is fitted around the outer periphery of the stud 311, with one end acting below the base plate 321 and the other end acting above the lifting platform 24.

[0031] In the grinding machine clamping mechanism 31, the base plate 321 and the lifting platform 24 are connected at one end with a movable connection and at the other end with an elastic connection. The base plate 321 and the lifting platform 24 can elastically open and close around the movable connection. The inclined plate of the base plate 321 is hinged to one side of the arc-shaped pressure plate 322 through the pressure plate hinge 325. The other side of the arc-shaped pressure plate 322 is detachably connected to the base plate 321. The grinding machine clamping mechanism 31 consists of a spring 312, a stud 311, and a pin 313. The spring 312 is sleeved on the stud 311. The upper end of the stud 311 is fixed to the base plate 321 of the grinding machine clamping mechanism 32. The lower end of the stud 311 passes through the hole 310 on the lifting platform 24. The pin 313 passes through the stud 311 and is fixed.

[0032] During operation, the operator places the grinder on the base plate 321, covers it with the arc-shaped pressure plate 322 and locks it, moves the device to the required position, so that the grinder contacts the surface to be grinded, and the clamping mechanism 31, under the action of the spring 312, presses the grinder against the surface to be grinded for grinding.

[0033] Based on the structure of the pressing mechanism 31 of this grinding machine, one end of the base plate 321 is movably connected to the lifting platform. The angle of the base plate 321 of the pressing mechanism 31 of the grinding machine can be adjusted within the stroke of the spring 312. When in use, push the handle 11, and the grinding machine contacts the surface to be ground and is subjected to force, compressing the spring 312, so that the grinding machine can adjust the angle according to the different grinding surfaces and maintain its contact with the surface to be ground under the pressure of the spring 312.

[0034] The base 1 is equipped with casters 12 and a braking device.

[0035] During operation, the operator can move and turn the entire device flexibly between different work areas, allowing the operator to easily move the device to the required work location. Before moving, release the brakes. Device Move it to the desired position and then secure the braking device.

[0036] The device can be equipped with a dust collection device.

[0037] The device is equipped with a lighting system.

[0038] The device is equipped with a protective gear storage box.

[0039] The 22 vertical split hydraulic jack can be operated manually or electrically.

[0040] The height of the lifting control console 223 is the same as the height of the handrail 11, which facilitates operation.

[0041] The grinding machine clamping mechanism 32 contains rubber / sponge.

[0042] Methods for performing grinding operations using this device include S1, move the device to the area where the operation needs to be carried out.

[0043] In the preferred embodiment of installing the caster wheel 12, the brake device is released, the handle 11 is pushed, the device is moved to the area where the work needs to be carried out, and the brake device is used to fix it.

[0044] S2, the grinder is installed on the grinder positioning mechanism 3 via the grinder clamping mechanism 32.

[0045] Open the arc-shaped pressure plate 322 of the grinding machine clamping mechanism 32, place the grinding machine on the base plate 321 of the grinding machine clamping mechanism 32, close the arc-shaped pressure plate 322, and clamp the grinding machine through the locking mechanism.

[0046] S3. Operate the hydraulic jack oil pump 222 on the lifting control console 223, which acts on the lifting column 23 through the oil cylinder 221. The lifting column 23 rises, driving the lifting platform 24 to rise until the grinder contacts the working area. When the height of the preferred lifting platform 24 is consistent with that of the handrail 11, and the brake is released, it is easy to operate the handrail 11 moving device with one hand to approach the area to be polished, while the other hand controls the hydraulic jack oil pump 222 to adjust the height of the lifting platform 24 so that the polisher is close to the surface to be polished.

[0047] S4. Continue to operate the hydraulic jack oil pump 222 on the lifting control console 223 to make the lifting platform 24 continue to rise. The reaction of the working area on the grinder causes the grinder to compress the base plate 321 downwards. Then the spring 313 provides elastic force to adjust the grinding disc of the grinder to a suitable working angle. S5. Push the handle 11, align the grinding disc of the grinder with the area to be ground, fix the brake device, and start the grinder to perform the grinding operation. S6. After the operation is completed, operate the hydraulic jack oil pump 222 on the lifting control console 223 to lower the lifting column 23 back to its original position, thereby driving the lifting platform 24 and the grinder to descend.

[0048] Based on the structure of the pressing mechanism 31 of this grinding machine, one end of the base plate 321 is movably connected to the lifting platform 24. The angle of the base plate 321 of the pressing mechanism 31 of the grinding machine can be adjusted within the stroke range of the spring 312. When in use, the operator pushes the handle 11, and the grinding machine contacts the surface to be ground and is subjected to force. The base plate 321 compresses the spring 312 and deforms, so that the grinding machine can adjust the angle according to the different grinding surfaces and maintain its contact with the surface to be ground under the pressure of the spring 312.

[0049] This device effectively solves the problems of traditional angle grinding operations, such as reliance on manual handling, high labor intensity, and poor operational stability, through the coordinated design of the base, lifting mechanism, and grinding machine positioning mechanism. The base is equipped with casters with brakes and a handrail, enabling flexible movement and stable fixation of the device. The lifting mechanism uses a separate hydraulic jack to drive the lifting column, which can precisely adjust the height of the grinding machine to adapt to different working areas. In the grinding machine positioning mechanism, one end of the obtuse-angled folding plate base is movably connected to the lifting platform, and the other end is connected to the elastic clamping mechanism through studs, springs, and pins. This allows it to open and close elastically around the movable end. Combined with the inner arc-shaped pressure plate with rubber / sponge (which can be detachably locked through a screw and handle), it can stably clamp the grinding machine and automatically adapt to the grinding angle during operation using the spring force. When in operation, the device can be started by moving the fixed device, clamping the grinder, hydraulically adjusting the height, and elastically adapting the angle. The entire process does not require manual lifting of the grinder, which greatly reduces the labor intensity of the operator and improves the safety of operation. At the same time, the precision of the hydraulic lifting and the angle adaptability of the elastic mechanism ensure the stability and grinding quality of the grinding operation. It is especially suitable for high-efficiency and high-quality upward angle grinding scenarios, which significantly optimizes the construction experience and work efficiency of upward angle operation.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
