Description

Technical Field

[0001] This utility model relates to the field of asbestos board production technology, specifically to a trolley for asbestos board production. Background Technology

[0002] In the production, processing, and transportation of asbestos boards, trolleys serve as indispensable transportation tools, playing a crucial role in the efficient and safe transfer of asbestos boards between different production stages. While existing trolleys for asbestos board production can basically meet the transportation needs in terms of structure and function, many problems still exist in actual use that urgently need to be solved. These problems not only affect production efficiency but also adversely impact the service life of the equipment and the labor intensity of the operators.

[0003] After the asbestos boards are placed on the trolley, their position may be slightly off. To ensure the balance of the asbestos boards during transportation and prevent them from tipping over due to a shift in the center of gravity, their position needs to be fine-tuned. However, current conventional trolley designs do not have a convenient operating structure specifically for fine-tuning the position of the asbestos boards. When adjusting the position of the asbestos boards, operators usually need to manually lift them and then place them back in the appropriate position. Since the asbestos boards themselves have a certain weight and large size, lifting them requires a lot of physical strength from the operators. This is especially true in scenarios where asbestos boards are frequently transferred, which greatly increases the labor intensity of the operators and reduces overall production efficiency.

[0004] If operators choose not to lift the asbestos sheet and instead push it directly onto the cart to adjust its position, this method, while seemingly labor-saving, will severely damage the lifespan of the cart. When moving the asbestos sheet, the wheels under the cart need to withstand lateral forces. However, the existing cart wheel design is mainly designed to withstand vertical weight and friction during straight forward or backward movement. It lacks an effective design to handle lateral forces. Long-term exposure to lateral forces will cause wear at the connection between the wheel and the axle, accelerating wheel damage and leading to problems such as inflexible rotation, jamming, or even detachment of the wheels. This not only affects the normal use of the cart but also increases the maintenance cost and replacement frequency of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a trolley for asbestos board production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trolley for asbestos board production, comprising: a trolley board, a handle, and casters. A handle is fixedly connected to one end of the upper surface of the trolley board, and casters are fixedly connected to the lower surface of the trolley board. A material support assembly is provided inside the trolley board, and multiple anti-slip blocks are evenly installed on the upper surface of the trolley board. The anti-slip blocks are connected to the trolley board through an installation assembly.

[0007] Preferably, the material support assembly includes: a support plate located inside the vehicle platform; multiple uprights uniformly fixed to the upper surface of the support plate; a slotted seat installed at the top of each upright; first bolts inserted into the four corners of the upper surface of the slotted seat, the first bolts penetrating the slotted seat and threadedly connected to the uprights; a first ball bearing slidably engaged at the top of the slotted seat; multiple openings for the uprights to pass through on the surface of the vehicle platform; and a pair of diagonal rods hinged to the lower surface of the support plate, the bottom ends of the diagonal rods hinged to a threaded cylinder, the inner wall of the threaded cylinder being threaded... The device is equipped with a double-ended screw, which is rotatably connected to the vehicle plate via ball bearings. A support block is fixedly connected to the bottom end of the threaded cylinder, and a sliding rod is provided on the inner wall of the support block. Both ends of the sliding rod are fixedly connected to the contact surface of the vehicle plate. A housing is fixedly connected to one end of the vehicle plate, and the output shaft of a servo motor installed inside the housing is fixedly connected to the double-ended screw. A control switch is installed on one side of the handle, and the control switch is electrically connected to the servo motor inside the housing via a connecting wire. A wiring groove is fitted on the outside of the connecting wire, and the wiring groove is fixedly connected to the vehicle plate.

[0008] Preferably, the slide rod passes through the support block via a cross cylinder, and a plurality of second ball bearings are slidably engaged inside the slide cylinder, with the second ball bearings in contact with the contact surface of the slide rod.

[0009] Preferably, a roller is fixed to the bottom end of the support block, and the roller ball is in contact with the inner bottom end of the vehicle plate.

[0010] Preferably, the mounting assembly includes: a groove formed at the center of the upper surface of the anti-slip block, a retaining plate pressed against the bottom of the groove, a second bolt inserted into the upper surface of the retaining plate, the second bolt passing through the retaining plate and a portion of the anti-slip block and threadedly connected to the vehicle panel.

[0011] Preferably, a plug is inserted above the interior of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This asbestos board production trolley has the following advantages over traditional technology: By coordinating the platform, handle, casters, anti-slip blocks, and material support assembly, the asbestos board to be transported is first placed on the upper surface of the platform, where it adheres tightly to the anti-slip blocks. Pushing the handle activates the casters, enabling transport. For fine-tuning the asbestos board's position, pressing the control switch powers the servo motor via the battery. The output shaft drives the double-headed screw to rotate, bringing the two threaded cylinders closer together. Through a diagonal transmission, the support plate moves upward, and the first ball bearing lifts the asbestos board, separating it from the anti-slip blocks. Closing the switch allows for minor adjustments to the asbestos board with minimal force, causing the first ball bearing to roll. This significantly reduces the physical exertion of operators when fine-tuning the asbestos board's position and avoids the lateral force exerted on the casters when moving the board after locking them, thus promoting the long-term normal use of the trolley.

[0013] Through the cooperation between the vehicle board, handle, casters, anti-slip blocks, and mounting components, if the anti-slip blocks on the upper surface of the vehicle board become severely worn during long-term use, the operator can rotate the second bolt in the groove on the surface of the severely worn anti-slip block counterclockwise. Once the second bolt separates from the vehicle board, the severely worn anti-slip block can be replaced to ensure that there is sufficient frictional resistance on the upper surface of the vehicle board, which facilitates the stable transportation of asbestos boards.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6 This utility model provides a technical solution: a trolley for asbestos board production, including: a trolley plate 1, a handle 2 and casters 3. The handle 2 is fixedly connected to one end of the upper surface of the trolley plate 1, and the casters 3 are fixedly connected to the lower surface of the trolley plate 1. The interior of the trolley plate 1 is provided with a material support assembly. Multiple anti-slip blocks 4 are evenly installed on the upper surface of the trolley plate 1. The anti-slip blocks 4 are connected to the trolley plate 1 through an installation assembly.

[0019] In the specific implementation process, it is worth noting that the vehicle platform 1 is made of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure that it has sufficient load-bearing capacity and structural stability, and can withstand the weight of the asbestos board and various external forces that may be encountered during transportation. The shape of the vehicle platform 1 is designed as a rectangle, and its size is customized according to actual production needs and the specifications of the asbestos board to ensure that the asbestos board can be placed stably. The handle 2 facilitates the application of force to move the vehicle platform 1. The outer side of the universal wheel 3 is fitted with high-quality rubber ring material, which has good wear resistance and shock absorption performance. The wheels are equipped with precision bearings to ensure flexible rotation and smooth movement on different ground surfaces, adapting to the complex working environment in the workshop.

[0020] Furthermore, the material support assembly includes: a support plate 5, located inside the vehicle platform 1; multiple uprights 6 are uniformly fixed to the upper surface of the support plate 5; a slot seat 7 is installed at the top of the uprights 6; first bolts 8 are inserted into the four corners of the upper surface of the slot seat 7; the first bolts 8 penetrate the slot seat 7 and are threadedly connected to the uprights 6; a first ball bearing 9 is slidably engaged at the top of the slot seat 7; multiple openings 10 are provided on the surface of the vehicle platform 1 for the uprights 6 to pass through; a pair of diagonal rods 11 are hinged to the lower surface of the support plate 5; a threaded cylinder 12 is hinged to the bottom end of the diagonal rods 11; and a double-ended screw 1 is threadedly connected to the inner wall of the threaded cylinder 12. 3. The double-ended screw 13 is rotatably connected to the car plate 1 via ball bearings. The bottom end of the threaded cylinder 12 is fixedly connected to the support block 14. The inner wall of the support block 14 is provided with a slide rod 15. Both ends of the slide rod 15 are fixedly connected to the contact surface of the car plate 1. One end of the car plate 1 is fixedly connected to the housing 16. The output shaft of the servo motor installed inside the housing 16 is fixedly connected to the double-ended screw 13. A control switch 25 is installed on one side of the handle 2. The control switch 25 is electrically connected to the servo motor inside the housing 16 via a connecting wire 26. A wiring groove 27 is fitted on the outside of the connecting wire 26. The wiring groove 27 is fixedly connected to the car plate 1.

[0021] In the specific implementation process, it is worth noting that the support plate 5 is made of high-strength steel plate to ensure that it can withstand the weight of the asbestos board and the stress generated during lifting. The column 6 is made of solid metal rod, which has high strength and rigidity and can stably support the slot seat 7. The slot seat 7 is made of engineering plastic material, which has a certain degree of elasticity and wear resistance. Its internal design has a groove that matches the first ball bearing 9, ensuring that the first ball bearing 9 can roll freely and will not fall off. The first ball bearing 9 is made of high-precision steel ball, and its surface is polished to reduce the friction between it and the asbestos board. The size of the opening 10 is precisely designed according to the diameter of the column 6 to ensure that the column 6 can pass smoothly. The design ensures smooth operation without wobbling. The diagonal rod 11 is connected by a metal hinge, allowing for flexible rotation. The threaded cylinder 12 has high internal thread precision and fits tightly with the double-ended screw 13, ensuring accurate transmission. The support block 14 is made of metal and has internal sliding holes that match the slide rod 15, ensuring smooth sliding. The housing 16 houses a servo motor and a rechargeable battery assembly. The control switch 25 is waterproof and dustproof, easy to operate, and can accurately control the start, stop, and direction of the servo motor. The connecting cable 26 uses wear-resistant and interference-resistant wires to ensure stable signal transmission. The cable tray 27 is made of plastic to fix and protect the connecting cable 26, preventing damage from external forces.

[0022] Furthermore, the slide rod 15 passes through the support block 14 via the cross cylinder 17, and multiple second balls 18 are slidably engaged inside the slide cylinder 17, with the second balls 18 in contact with the contact surface of the slide rod 15.

[0023] In the specific implementation process, it is worth noting that the cross cylinder 17 is made of metal and its internal surface is precision machined to ensure the matching accuracy with the second ball 18. The second ball 18 is made of high-precision steel ball, and the contact surface with the slide bar 15 is specially treated to reduce friction and make the support block 14 slide more smoothly on the slide bar 15. This design can effectively reduce the resistance when the support block 14 moves, improve the working efficiency of the material support assembly, and extend the service life of each component.

[0024] Furthermore, a roller 19 is fixed to the bottom end of the support block 14, and the roller 19 fits against the inner bottom end of the car plate 1.

[0025] In the specific implementation process, it is worth noting that the roller 19 is composed of a wheel frame and a wheel body. The wheel body is rotatably connected to the wheel frame through an axle. The top of the wheel frame is fixedly connected to the support block 14. The wheel body fits against the inner bottom of the car plate 1, which can reduce the burden on the double-headed screw 13.

[0026] Furthermore, the mounting components include: a groove 20, which is formed at the center of the upper surface of the anti-slip block 4; a retaining plate 21 is pressed against the bottom of the groove 20; a second bolt 22 is inserted into the upper surface of the retaining plate 21; the second bolt 22 passes through the retaining plate 21 and a part of the anti-slip block 4 and is threadedly connected to the vehicle plate 1.

[0027] In the specific implementation process, it is worth noting that the anti-slip plate 21 is made of metal, which has a certain elasticity and strength. It can evenly distribute the pressure of the second bolt 22 on the anti-slip block 4, preventing the anti-slip block 4 from being damaged due to excessive local stress. This installation method can make it convenient and quick to replace the anti-slip block 4, improving the maintenance efficiency of the trolley.

[0028] Furthermore, a plug 23 is inserted into the upper part of the inside of the groove 22.

[0029] In the specific implementation process, it is worth noting that the plug 23 is made of rubber, which has a certain degree of elasticity and sealing performance. Its shape matches the opening of the groove 22, allowing it to be tightly inserted into the groove 22. The function of the plug 23 is to prevent dust, debris, etc. from entering the interior of the groove 22, protecting the second bolt 22 and the abutment 21 from corrosion and damage. At the same time, it makes the appearance of the trolley cleaner and more aesthetically pleasing, and also prevents the second bolt 22 from abrading the asbestos board. When it is necessary to disassemble the anti-slip block 4, simply remove the plug 23 for operation.

[0030] Working principle: Asbestos board handling principle: When transporting asbestos boards, the operator first places the asbestos board to be transported steadily on the upper surface of the cart 1. At this time, the anti-slip block 4 set on the upper surface of the cart 1 will fit tightly against the asbestos board, effectively preventing the asbestos board from sliding during the transport process by increasing the friction of the contact surface. Then, the operator holds the handle 2 and applies a pushing force. The universal wheels 3 at the bottom of the cart 1 start to roll under the action of the pushing force, thereby driving the entire cart and the asbestos board placed on the cart to move together, realizing the transport operation of the asbestos board. The design of the universal wheels 3 allows the cart to move flexibly in different directions to adapt to various transport path requirements.

[0031] The principle of fine-tuning the position of asbestos boards: After the asbestos board is placed on the cart, if a deviation in its position is found, the position of the asbestos board needs to be fine-tuned to improve the overall balance of the cart. At this time, the material support assembly plays a key role. The operator presses the control switch 25, triggering the battery pack inside the housing 16 to power the servo motor. After the servo motor is powered on, its output shaft begins to rotate clockwise, which in turn drives the connected double-ended screw 13 to rotate clockwise synchronously. During the rotation of the double-ended screw 13, the two threaded cylinders 12, due to their threaded engagement with the double-ended screw 13, will tend to move closer to each other. The movement of the threaded cylinders 12 is transmitted through the inclined rod 11, which converts the linear motion of the threaded cylinders 12 into the upward movement of the support plate 5. When the support plate 5 moves upward, it will drive the column 6, the slot seat 7, and the components installed on it. The first ball bearings 9 in the slot 7 move upward together. When the multiple first ball bearings 9 rise to contact the asbestos board and lift it up, separating the asbestos board from the anti-slip block 4, the operator closes the control switch 25, the servo motor stops running, and the tray 5, the first ball bearings 9, and the asbestos board also stop moving upward. At this time, since the first ball bearings 9 on the lower surface of the asbestos board can roll freely inside the slot 7, the operator only needs to apply a small force to the asbestos board to easily make a fine adjustment of its position in the horizontal direction. This design not only greatly reduces the physical exertion of the operator when fine-tuning the placement of the asbestos board, but also effectively avoids the intensity of the lateral force on the universal wheel 3 when pushing the asbestos board after the universal wheel 3 is locked, thereby extending the overall service life of the trolley and ensuring its long-term normal use.

[0032] The principle of resetting the asbestos board after fine-tuning: After the asbestos board position is fine-tuned, press the control switch 25 to rotate the servo motor output shaft counterclockwise, moving the support plate 5, column 6, slot seat 7 and first ball bearing 9 downwards to reset them. After the first ball bearing 9 is inside the opening 10, stop pressing the control switch 25. At this time, the lower surface of the asbestos board is no longer supported by the first ball bearing 9, and the lower surface of the asbestos board is once again in contact with the anti-slip block 4, completing the reset operation after the asbestos board fine-tuning.

[0033] Anti-slip block replacement principle: During prolonged use of the trolley, the anti-slip blocks 4 on the upper surface of the trolley panel 1 may experience severe wear, affecting their anti-slip effect on the asbestos sheets. In this case, the mounting assembly provides a convenient way to replace the anti-slip blocks. The operator simply needs to rotate the second bolt 22 counterclockwise in the groove 20 on the surface of the severely worn anti-slip block 4. As the second bolt 22 rotates, the threaded connection between it and the trolley panel 1 gradually loosens. Once the second bolt 22 is completely separated from the trolley panel 1, the operator can easily remove the severely worn anti-slip block 4 from the trolley panel 1. Then, the operator places the new anti-slip block 4 in the appropriate position, passes the second bolt 22 through the hole in the groove 20 on the surface of the anti-slip block 4, and then rotates the second bolt 22 clockwise to tightly connect it to the trolley panel 1. This method allows for quick and convenient replacement of the anti-slip blocks, ensuring sufficient frictional resistance on the upper surface of the trolley panel 1, thereby guaranteeing the stability of the asbestos sheets during handling and achieving stable transportation of the asbestos sheets.
