Although this patent has the advantage of easily lifting the spherical stone block by placing a V-shaped fork at the bottom of the spherical stone block and using the lever principle with the traveling wheels as the fulcrum by pressing the handling support tube, the technical solution of this patent still has the following defects in actual use: After the device lifts the spherical stone block, because the V-shaped fork has no protective device, the spherical stone block is prone to movement when moving, which may cause it to fall and affect personnel safety. Utility Model Content

[0004] The purpose of this utility model is to provide a stone block handling mechanism to solve the problem that when a spherical stone block is raised, it is easy for the stone block to move and fall, affecting personnel safety, because the V-shaped fork has no protective device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stone block transport mechanism, including a movable frame, a fixed seat fixedly connected to the top of the movable frame, a support component being lifted and lowered on one side of the fixed seat, the support component including a lifting platform, and two front shovels fixedly connected to one side of the lifting platform; The two front shovels are fitted with fixing components on their outer sides. The fixing components include a first fixing sleeve and a second fixing sleeve. The first fixing sleeve and the second fixing sleeve are each provided with an arc-shaped guard plate on their opposite sides. A spherical stone block is held between the two arc-shaped guard plates.

[0006] In a preferred embodiment, the top ends of the first fixing sleeve and the second fixing sleeve are respectively connected to a first fixing block and a second fixing block. A fixing rod is fixed to the side of the second fixing block near the first fixing sleeve. An arc-shaped guard plate is fixedly connected to one end of the fixing rod. A clamping screw is provided on the side of both the first fixing sleeve and the second fixing sleeve.

[0007] In a preferred embodiment, a slide rod is slidably installed inside the first fixing block, with both ends of the slide rod passing through the first fixing block. Additionally, an arc-shaped guard plate is fixed to one end of the slide rod near the second fixing block, and a push plate is fixed to the other end of the slide rod.

[0008] In a preferred embodiment, the first fixing block has a through groove for the slide rod to slide through, and a clamping screw is threaded on the top of the first fixing block. The bottom end of the clamping screw extends into the through groove and presses against the surface of the slide rod.

[0009] In a preferred embodiment, the fixed base has a rotating groove on the side near the lifting platform, and a lead screw is rotatably connected between the two ends inside the rotating groove. A lifting block is threaded onto the outside of the lead screw, and the lifting block is fixedly connected to the lifting platform.

[0010] In a preferred embodiment, sliding grooves are provided on both sides of the rotating groove. The two sliding grooves are opened on one side of the fixed base, and two sliding blocks are fixedly connected to one side of the lifting platform. The two sliding blocks are slidably installed inside the corresponding sliding grooves.

[0011] In a preferred embodiment, the four corners of the bottom of the mobile frame are provided with moving wheels, the top of the fixed base is fixedly connected to a servo motor, the drive shaft of the servo motor is fixedly connected to a lead screw, and an auxiliary handle is fixed on the side of the fixed base away from the lifting platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This stone block handling mechanism features two adjustable arc-shaped guard plates forming a clamping structure specifically designed for spherical stone blocks. The curvature of the arc-shaped guard plates matches the outer edge of the stone block, and together with the inner elastic buffer layer, it can achieve a tight clamping of the stone block. At the same time, the clamping distance can be flexibly adjusted according to the size of the stone block through the cooperation of the sliding rod and fixing screws, ensuring that spherical stone blocks of various sizes can be stably fixed, effectively solving the problem of stone blocks easily slipping and bumping in traditional handling methods.

[0013] This stone block handling mechanism allows for flexible adjustment of its position on the front shovel via tightening screws. The clamping distance can be adjusted by using a sliding rod to drive the arc-shaped guard plate, enabling the device to adapt to spherical stone blocks of various diameters. This eliminates the need for dedicated handling equipment for stone blocks of different sizes, reducing construction costs. Additionally, the fixed components can be used to assist in moving the spherical stone blocks on the front shovel or to place the fixed components on the ground to clamp and fix the spherical stone blocks.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figure 1 and Figure 3 This utility model provides a stone block transport mechanism, including a mobile frame 1, a fixed seat 2 fixedly connected to the top of the mobile frame 1, a support component that is lifted and lowered on one side of the fixed seat 2, the support component including a lifting platform 5, and two front shovels 6 fixedly connected to one side of the lifting platform 5; In this embodiment, the mobile frame 1 is a rectangular frame structure made of high-strength steel to ensure the load-bearing capacity and stability of the overall structure. The top of the mobile frame 1 is fixedly connected to the fixed seat 2 by welding. The fixed seat 2 is a vertically arranged rectangular plate structure, and the connection part between it and the mobile frame 1 is provided with reinforcing ribs to further improve the connection strength. The two front shovels 6 are symmetrically distributed, and their cross-sections are L-shaped. The shovel head of the front shovel 6 adopts a rounded transition design to avoid scratching the surface of the stone block when shoveling it. The front shovel 6 is made of wear-resistant alloy steel to extend its service life.

[0019] Please see Figure 1 and Figure 2 The fixed base 2 has a rotating groove 4 on the side near the lifting platform 5. A lead screw is rotatably connected between the two ends inside the rotating groove 4. A lifting block is threaded on the outside of the lead screw. The lifting block is fixedly connected to the lifting platform 5. The four corners of the bottom of the movable frame 1 are equipped with movable wheels 15 (the movable wheels 15 are wheels with built-in brake pads and are existing products). The top of the fixed base 2 is fixedly connected to a servo motor 3. The drive shaft of the servo motor 3 is fixedly connected to the lead screw. An auxiliary handle 14 is fixed on the side of the fixed base 2 away from the lifting platform 5.

[0020] In this embodiment, the caster wheel 15 is a universal wheel with a braking mechanism, which makes it easy for the operator to push the device to change the direction of movement flexibly, and can fix the device in a designated position through the braking structure during operation to prevent slippage. The auxiliary handle 14 has a U-shaped structure and its surface is covered with a non-slip sponge sleeve, which makes it easy for the operator to hold. Together with the caster wheel 15, the overall movement and direction adjustment of the device can be realized. The drive shaft of the servo motor 3 is fixedly connected to the top of the lead screw through a coupling, providing stable power for the rotation of the lead screw. The servo motor 3 is equipped with a controller and a reducer. The controller can realize the forward and reverse rotation control of the servo motor 3, thereby controlling the lifting action of the lifting platform 5. The reducer can reduce the output speed of the servo motor 3 and increase the torque, ensuring that the lifting platform 5 can stably drive the stone block to rise and fall.

[0021] Please see Figure 1 and Figure 4 Two front shovels 6 are fitted with fixing components on their outer sides. The fixing components include a first fixing sleeve 7 and a second fixing sleeve 8. An arc-shaped guard plate 12 is provided on the opposite side of the first fixing sleeve 7 and the second fixing sleeve 8. A spherical stone block is held between the two arc-shaped guard plates 12. The top ends of the first fixing sleeve 7 and the second fixing sleeve 8 are respectively connected to a first fixing block 10 and a second fixing block. A fixing rod is fixed on the side of the second fixing block near the first fixing sleeve 7. One of the arc-shaped guard plates 12 is fixedly connected to one end of the fixing rod. A clamping screw 9 is provided on the side of the first fixing sleeve 7 and the second fixing sleeve 8. An elastic buffer layer is fixedly connected on the opposite side of the two arc-shaped guard plates 12. A slide rod 11 is slidably installed inside the first fixing block 10. Both ends of the slide rod 11 pass through the first fixing block 10. Another arc-shaped guard plate 12 is fixed to one end of the slide rod 11 near the second fixing block. A push plate 16 is fixed to the other end of the slide rod 11. The first fixing block 10 has a through groove for the slide rod 11 to slide through. A fixing screw 13 is threaded on the top of the first fixing block 10. The bottom end of the fixing screw 13 extends into the through groove and presses against the surface of the slide rod 11.

[0022] In this embodiment, the push plate 16 is a plate-shaped structure with a diameter larger than that of the slide rod 11, making it easier for the operator to push the slide rod 11 to move. After adjusting the position of the slide rod 11 by the push plate 16, tightening the fixing screw 13 will fix the slide rod 11 in the current position, thereby keeping the two arc-shaped guard plates 12 in a stable clamping state on the spherical stone block.

[0023] Both sides of the rotating groove 4 are provided with sliding grooves. The two sliding grooves are opened on one side of the fixed base 2, and two sliding blocks are fixedly connected to one side of the lifting platform 5. The two sliding blocks are slidably installed in the corresponding sliding grooves.

[0024] Working principle: Move the entire mechanism to the vicinity of the stone block to be moved, then start the servo motor 3 to rotate the lead screw, and then the lifting platform 5 drives the front shovel 6 to descend. According to the size of the spherical stone block to be moved, loosen the clamping screws 9 on the first fixed sleeve 7 and the second fixed sleeve 8, and adjust the position of the first fixed sleeve 7 and the second fixed sleeve 8 on the front shovel 6 so that the initial distance between the two arc-shaped guard plates 12 is slightly larger than the diameter of the stone block. After the adjustment is completed, tighten the clamping screws 9 again to fix the first fixed sleeve 7 and the second fixed sleeve 8 on the front shovel 6. At the same time, loosen the fixing screws 13 on the first fixed block 10 so that the slide rod 11 is in a sliding state.

[0025] Pushing the push plate 16 causes the slide rod 11 to slide along the through groove of the first fixing block 10 towards the stone pier. The slide rod 11 causes the corresponding arc-shaped guard plate 12 to move synchronously until the two arc-shaped guard plates 12 are tightly attached to the outer surface of the stone pier, thus clamping and fixing the stone pier. At this time, tighten the fixing screw 13 on the first fixing block 10 to fix the slide rod 11 and prevent the arc-shaped guard plate 12 from loosening.

[0026] By turning the servo motor 3 counterclockwise, the drive screw moves the lifting block upward, which in turn drives the front shovel 6 and the fixed stone block to be lifted synchronously through the lifting platform 5, raising them to a suitable height for subsequent movement.

[0027] In the above scheme, it should be noted that: the servo motors 3 in this application are all existing products, and the specific structure, electrical connection method (circuit layout) and working principle of the servo motors 3 are all existing publicly disclosed technical means. At the same time, the servo motors 3 can be turned on or off manually, which will not be described in detail here. It should also be noted that this application is also equipped with an existing power supply structure (e.g., a battery) for use. The power supply structure (e.g., a battery) can be used to power the servo motor 3. The power supply structure (e.g., a battery) and the charging method both adopt mature and publicly available technical means in this field, which will not be described in detail here.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
