Description

Technical Field

[0001] This utility model belongs to the field of block transfer and hoisting technology, specifically relating to a manual lever lifting and moving device for installing blocks. Background Technology

[0002] In road construction and maintenance, the handling and installation of curb stones is crucial and labor-intensive. According to statistics, when manually handling and installing curb stones, workers bend over an average of 50-80 times per hour. Prolonged bending and exertion easily lead to fatigue and injury. With the expansion of project scale and increasing efficiency requirements, existing simple tools such as forklifts and rope hoists have many shortcomings. The former lacks flexibility and is costly, with a simple forklift costing approximately 30,000-50,000 yuan. The latter is complex to operate and has low safety. Currently, there is a lack of specialized tools that are easy to operate, low-cost, highly efficient, safe, and capable of precisely controlling the handling and installation of curb stones. This makes it difficult to meet the demands of modern road construction for rapid and accurate curb stone installation. Therefore, the development of such a device has become an urgent need for municipal engineering projects.

[0003] Currently, an existing curbstone transfer and hoisting device with announcement number CN215793821U includes tires, crossbeams, trusses, lifting rods, hooks, lifting rings, lifting clamps, fixtures, and anti-loosening rods. The two handles of the fixtures are provided with connecting holes in the middle, which are used to connect the anti-loosening rods. By adjusting the extension or retraction of the anti-loosening rods, the clamping force of the anti-slip pads on the curbstones can be adjusted, thereby achieving the clamping or loosening of the curbstones and effectively reducing potential safety hazards during construction.

[0004] However, there is also a problem: the clamping mechanism of the device is too complicated, requiring manual adjustment of the anti-loosening rod, which is very troublesome. Utility Model Content

[0005] This solution provides a manual lever lifting and moving device for installing blocks, which solves the problem of overly complicated operation when clamping curb stones.

[0006] This solution provides a manually operated lever lifting and moving device for installing blocks, including a chassis;

[0007] Rollers: The rollers are rotatably connected to the chassis;

[0008] Support column: The support column is fixedly connected to the chassis;

[0009] Lifting rod: The lifting rod is fixedly connected to the support column, and the lifting rod is equipped with a lifting bracket;

[0010] Clamping mechanism: The clamping mechanism cooperates with the lifting rod and is used to clamp the curb stone;

[0011] The clamping and lifting mechanism includes:

[0012] The lifting ring, clamp number one, and wire rope are provided, with the lifting ring connected to the lifting support.

[0013] The first clamp includes a long rod and a clamping plate. The long rod includes a first long rod and a second long rod. The first long rod and the second long rod are connected crosswise by bolts and are rotatably connected.

[0014] The clamping plate includes a first clamping plate and a second clamping plate. The first clamping plate is fixedly connected to a first long rod, and the second clamping plate is fixedly connected to a second long rod. The first clamping plate and the second clamping plate cooperate with the curb stone.

[0015] The wire rope passes through the lifting ring, with one end of the wire rope fixedly connected to the first long rod and the other end fixedly connected to the second long rod.

[0016] The principle of this solution is as follows: the operator pushes the support column to make the roller rotate, which drives the entire equipment to move to the curb. Then, the operator adjusts the distance between the clamping arms of the conveying mechanism according to the curb specifications to clamp the object. The entire adjustment process can be completed within 1 minute. Next, by rotating the lifting rod, the long rod and clamping plate are loosened and opened, placing the curb between the two long rods and clamping plates.

[0017] Rotate the lifting boom to lift the curbstone. At this point, the long boom and clamping plate will automatically clamp together under the tension of the steel cable and the weight of the curbstone. Then, move it above the installation area, operate the hand support to adjust the height, and use the fine-tuning device to adjust the curbstone's posture.

[0018] Finally, the curbstone was precisely placed in the preset position and plastered to fix it, completing the installation. Each step was closely connected, efficient and orderly.

[0019] The beneficial effects of this solution are: it simplifies the gripping process, and the long pole and clamping plate automatically clamp and release due to the gravity of the curb stone itself, thereby improving gripping efficiency.

[0020] Furthermore, the roller includes a front wheel and a rear wheel, the front wheel being larger than the rear wheel, the front wheel cooperating with the rear wheel, and the front wheel being used for load-bearing.

[0021] The larger front wheels, primarily used for load-bearing, can support the majority of the equipment's weight. The boom rotates via the front wheels, ensuring a more stable distribution of the equipment's center of gravity, thus improving overall stability. The larger front wheels provide a greater contact area and better traction. This results in smoother start-up, stopping, and turning, enhancing the operator's sense of control, especially in situations requiring precise movement.

[0022] Larger front wheels allow for easier passage over obstacles or uneven terrain, improving the equipment's off-road capability and enabling its use in more diverse environments, such as construction sites and outdoor areas. Smaller rear wheels are typically used for steering, making steering more agile. Although the front wheels bear the main load, the smaller rear wheels can respond quickly to steering commands, improving the overall maneuverability of the equipment.

[0023] Furthermore, it also includes steel reinforcement bracing, one end of which is fixedly connected to the support column and the other end is fixedly connected to the chassis.

[0024] The steel reinforcement bracing connects the support column and the chassis, forming a stable triangular structure. This significantly enhances the lateral stability of the entire equipment, preventing tilting or tipping during operation, especially when working on uneven or sloping ground.

[0025] The steel reinforcement bracing transfers part of the vertical load on the support column to the chassis. This effectively distributes the total weight of the equipment, reduces the load on individual components, and thus improves the overall load-bearing capacity and durability of the structure.

[0026] By connecting the support columns and the chassis, the steel reinforcement bracing increases the overall torsional stiffness of the equipment. This makes the equipment more stable when subjected to external torques (such as the torsional force generated when moving heavy objects), reducing the possibility of deformation. The steel reinforcement bracing can absorb and disperse earthquake or other external impacts, improving the equipment's seismic resistance in emergency situations and ensuring its stability and safety.

[0027] Furthermore, it also includes a steel reinforcement fence ring, through which the lifting rod and the support column are fixedly connected. The steel reinforcement fence ring firmly connects the lifting rod and the support column together, significantly enhancing the connection strength between the two, ensuring that the lifting rod will not loosen or detach under heavy loads, and improving the reliability of the overall structure. The steel reinforcement fence ring provides additional support points for the lifting rod, distributing the pressure on the lifting rod when lifting heavy objects, reducing the risk of deformation or damage caused by excessive force at a single point, and extending the service life of the equipment.

[0028] By connecting the lifting rod and the support column, the steel fence ring forms a closed, rigid ring structure. This enhances the overall rigidity of the equipment, enabling it to remain stable under external impacts or vibrations and reducing the possibility of structural deformation.

[0029] Furthermore, the lifting ring is an arc-shaped lifting ring. The arc-shaped design allows it to grip the lifting rod or connection point more firmly. Compared to traditional straight lifting rings, the arc-shaped structure provides a larger contact area and better wrapping, thereby enhancing the gripping force and ensuring the stability and reliability of the connection.

[0030] The arc-shaped structure of the bow-shaped lifting ring effectively distributes the load pressure applied to it. This reduces the risk of excessive stress at a single point, avoids damage caused by localized stress concentration, and extends the service life of the lifting ring and related components. Bow-shaped lifting rings are typically designed with open or closed mechanisms for easy and quick installation and removal. This simplifies the connection process between the lifting ring and the lifting rod or other components, reduces maintenance costs and time, and improves work efficiency.

[0031] Furthermore, it also includes a second clamp, which replaces the first clamp. The second clamp includes a square steel block, a U-shaped plate, and a steel handle. The square steel block is fixedly connected to the lifting ring. The U-shaped plate includes a first U-shaped plate and a second U-shaped plate, both of which are rotatably connected to the square steel block and are designed to cooperate with each other.

[0032] The steel handle includes a first steel handle and a second steel handle. The first steel handle is fixedly connected to a first U-shaped plate, and the second steel handle is fixedly connected to a second U-shaped plate. The first steel handle and the second steel handle cooperate with each other.

[0033] The operator installs clamp number two onto the equipment, ensuring the square steel block is securely connected to the lifting ring. Based on the shape and size of the object to be clamped, the operator manually adjusts the positions of the first and second U-shaped plates to ensure they are appropriately spaced. The object is placed between the first and second U-shaped plates, and then the U-shaped plates are closed and clamped by pulling or pushing the steel handle. After ensuring the clamp is securely holding the object, the operator can lift the entire device using the lifting ring to safely transport the object to the target location. Once at the designated location, the operator fine-tunes the device height to ensure the object's posture is correct, and finally releases the steel handle, releasing the U-shaped plates and placing the object smoothly.

[0034] This mechanism achieves flexible adjustment of the two U-shaped plates according to the shape and size of the object by rotating the first and second U-shaped plates to the square steel block. This ensures that the clamp can adapt to objects of different shapes and sizes, improving the clamping flexibility and applicability.

[0035] When the first and second U-shaped plates are closed, their interlocking design creates a self-locking mechanism. After clamping an object, the U-shaped plates automatically lock in position to prevent accidental loosening due to external forces, ensuring clamping stability. The square steel block serves as a base, not only fixedly connected to the lifting ring but also supporting the U-shaped plates and steel handles. The U-shaped structure is more suitable for small curb stones compared to the long rod type.

[0036] The rigidity and strength of the square steel block effectively disperse the pressure borne by the fixture during operation, reduce local stress concentration, and extend the service life of the fixture.

[0037] Furthermore, the steel handle is a U-shaped handle. The U-shaped steel handle makes it less likely for the curb stone to fall off.

[0038] Furthermore, it also includes an anti-sway mechanism, which comprises a connecting rod, a guide block, and a guide rail. The guide rail is fixedly connected to the support column. One end of the connecting rod is hinged to a long rod, and the other end is hinged to the guide block. The guide block is slidably connected to the guide rail. When transporting and grabbing curb stones, strong winds or steep slopes often cause the clamping mechanism to sway, resulting in the curb stone falling off or unstable clamping. This mechanism reduces the sway range of the clamping mechanism through the connecting rod, and the presence of the guide rail does not affect the vertical movement of the clamping mechanism.

[0043] As attached Figure 1 As shown:

[0044] This solution provides a manual lever lifting and moving installation device for paving blocks, including a chassis 8; rollers: the rollers are rotatably connected to the chassis 8; a support column 7: the support column 7 is fixedly connected to the chassis 8; a lifting rod 1: the lifting rod 1 is fixedly connected to the support column 7, and a lifting bracket 4 is provided on the lifting rod 1; a clamping mechanism: the clamping mechanism is used to clamp the curbstone; the clamping mechanism includes: a lifting ring, a first clamp, and a steel wire rope 14, the lifting ring being connected to the lifting bracket 4; the first clamp includes a long rod and a clamping plate, the long rod including a first long... The first long rod 15 and the second long rod 17 are cross-connected by bolts 12 and are rotatably connected; the clamping plate includes a first clamping plate 19 and a second clamping plate 18, the first clamping plate 19 is fixedly connected to the first long rod 15, and the second clamping plate 18 is fixedly connected to the second long rod 17; the wire rope 14 passes through the lifting ring, one end of the wire rope 14 is fixedly connected to the ring 13 on the first long rod 15, and the other end is fixedly connected to the ring 13 on the second long rod 17.

[0045] It also includes a steel bar brace 11, one end of which is fixedly connected to the support column 7 and the other end is fixedly connected to the chassis 8.

[0046] The steel reinforcement diagonal brace 11 connects the support column 7 and the base plate 8, forming a stable triangular structure. This significantly enhances the lateral stability of the entire equipment, preventing tilting or overturning during operation, especially when working on uneven or sloping ground.

[0047] The steel reinforcement brace 11 transfers part of the vertical load on the support column 7 to the chassis 8. This effectively distributes the total weight of the equipment, reduces the load on individual components, and thus improves the overall load-bearing capacity and durability of the structure.

[0048] By connecting the support column 7 and the chassis 8, the steel reinforcement brace 11 increases the overall torsional stiffness of the equipment. This makes the equipment more stable when subjected to external torques (such as the torsional force generated when moving heavy objects), reducing the possibility of deformation. The steel reinforcement brace 11 can absorb and disperse earthquake or other external impact forces, improving the equipment's seismic resistance in emergency situations and ensuring its stability and safety.

[0049] It also includes a steel reinforcement ring 6, through which the lifting rod 1 and the support column 7 are fixedly connected. The steel reinforcement ring 6 firmly connects the lifting rod 1 and the support column 7 together, significantly enhancing the connection strength between the two, ensuring that the lifting rod 1 will not loosen or detach under heavy loads, and improving the reliability of the overall structure. The steel reinforcement ring 6 provides additional support points for the lifting rod 1, distributing the pressure on the lifting rod 1 when lifting heavy objects, reducing the risk of deformation or damage caused by excessive force at a single point, and extending the service life of the equipment.

[0050] By connecting the lifting rod 1 and the support column 7, the steel reinforcement fence ring 6 forms a closed, rigid ring structure. This enhances the overall rigidity of the equipment, enabling it to remain stable under external impacts or vibrations and reducing the possibility of structural deformation.

[0051] The lifting ring is an arc-shaped lifting ring 5. The design of the arc-shaped lifting ring 5 allows it to grip the lifting rod 1 or the connection point more firmly. Compared with the traditional straight lifting ring, the arc-shaped structure provides a larger contact area and better wrapping, thereby enhancing the gripping force and ensuring the stability and reliability of the connection.

[0052] The arc-shaped structure of the bow-shaped lifting ring 5 effectively distributes the load pressure applied to it. This reduces the risk of excessive stress at a single point, avoids damage caused by localized stress concentration, and extends the service life of the lifting ring and related components. The bow-shaped lifting ring 5 is typically designed with an open or closed mechanism for easy and quick installation and removal. This simplifies the connection process between the lifting ring and the lifting rod 1 or other components, reduces maintenance costs and time, and improves work efficiency.

[0053] The system also includes a torque-extending cable support rod 2 and a torque-extending cable 3, which is connected to both ends of the lifting rod 1. One end of the torque-extending cable support rod 2 supports the torque-extending cable 3, and the other end is fixedly connected to the lifting rod 1. The operator installs the torque-extending cable support rod 2 onto the lifting rod 1, ensuring a secure connection. The torque-extending cable 3 is then connected to both ends of the lifting rod 1, ensuring a secure and loose connection. By pulling or pushing the torque-extending cable 3, the operator can easily lift or move the lifting rod 1 using its leverage effect and gear transmission mechanism. During operation, the torque-extending cable support rod 2 provides stable support, ensuring smooth and safe operation. After the object is moved or installed, the operator can release the torque-extending cable 3 to loosen the lifting rod 1, safely completing the task.

[0054] The torque extender cable 3 amplifies the small force applied by the operator into a large output torque through the lever principle and gear transmission mechanism. This allows the operator to easily lift or move heavy objects with less force, greatly improving work efficiency, especially in situations requiring high torque output.

[0055] The moment-increasing cable support rod 2 transfers part of the load on the lifting rod 1 to its own structure. This effectively disperses the pressure on the lifting rod 1, reduces the risk of excessive stress at a single point, and extends the service life of the lifting rod 1 and other related components.

[0056] The design of the torque extender cable support rod 2 simplifies the installation and disassembly process between the torque extender cable and the lifting rod 1. This facilitates the assembly, disassembly, and maintenance of the equipment, reduces maintenance costs and time, and improves the maintainability of the equipment.

[0057] As attached Figure 1 , Figure 2 As shown:

[0058] It also includes an anti-sway mechanism, which comprises a connecting rod, a guide block, and a guide rail. The guide rail is fixedly connected to the support column 7. One end of the connecting rod is hinged to a long rod, and the other end is hinged to the guide block. The guide block is slidably connected to the guide rail. When transporting and grabbing curb stones, strong winds or steep slopes often cause the clamping mechanism to sway, resulting in the curb stone falling off or unstable clamping. This mechanism reduces the sway range of the clamping mechanism through the connecting rod, and the presence of the guide rail does not affect the vertical movement of the clamping mechanism.

[0059] As attached Figure 1 , Figure 3 As shown:

[0060] It also includes a second clamp, which replaces the first clamp. The second clamp includes a square steel block 21, a U-shaped plate, and a steel handle. The square steel block 21 is fixedly connected to the lifting ring. The U-shaped plate includes a first U-shaped plate 22 and a second U-shaped plate 24. Both the first U-shaped plate 22 and the second U-shaped plate 24 are rotatably connected to the square steel block 21, and the first U-shaped plate 22 and the second U-shaped plate 24 are the same size.

[0061] The steel handle includes a first steel handle 23 and a second steel handle 20. The first steel handle 23 is fixedly connected to the first U-shaped plate 22, and the second steel handle 20 is fixedly connected to the second U-shaped plate 24. When the first steel handle 23 and the second steel handle 20 are closed, they can just frame the curb stone.

[0062] The operator installs the second clamp onto the equipment, ensuring the square steel block 21 is securely connected to the lifting ring. Based on the shape and size of the object to be clamped, the operator manually adjusts the positions of the first U-shaped plate 22 and the second U-shaped plate 24 to ensure they are at an appropriate distance. The object is placed between the first U-shaped plate 22 and the second U-shaped plate 24, and then the U-shaped plates are closed and clamped by pulling or pushing the steel handle. After ensuring the clamp is securely holding the object, the operator can lift the entire device using the lifting ring to safely transport the object to the target location. Upon reaching the designated location, the operator fine-tunes the device height to ensure the object's posture is correct, and finally releases the steel handle, releasing the U-shaped plates and placing the object stably.

[0063] This mechanism rotatably connects the first U-shaped plate 22 and the second U-shaped plate 24 to the square steel block 21, allowing the two U-shaped plates to be flexibly adjusted according to the shape and size of the object. This ensures that the clamp can adapt to objects of different shapes and sizes, improving the clamping flexibility and applicability.

[0064] When the first U-shaped plate 22 and the second U-shaped plate 24 are closed, their interlocking design forms a self-locking mechanism. After clamping the object, the U-shaped plates automatically lock in position to prevent accidental loosening due to external forces, ensuring clamping stability. The square steel block 21 serves as a base, not only fixedly connected to the lifting ring but also supporting the U-shaped plates and steel handle. The U-shaped structure is more suitable for small curb stones compared to the long rod type.

[0065] The rigidity and strength of the square steel block 21 effectively disperse the pressure borne by the fixture during operation, reduce local stress concentration, and extend the service life of the fixture.

[0066] The steel handle is a U-shaped handle. The U-shaped steel handle makes it less likely for the curb stone to fall off.

[0067] As attached Figure 1 , Figure 2 , Figure 3 As shown:

[0068] The principle behind this solution is:

[0069] The operator pushes the support column 7 to rotate the rollers, which in turn moves the entire device to the curb. Then, the operator adjusts the distance between the clamping arms of the handling mechanism according to the curb specifications to clamp the object. The entire adjustment process can be completed within 1 minute. Next, by rotating the lifting rod 1, the front wheel 10 remains stationary and is used for load bearing, while the rear wheel 9 is raised and rotated, causing the long rods and clamping plates to loosen and open, placing the curb between the two long rods and clamping plates.

[0070] Rotate the lifting boom 1 to lift the curbstone. At this time, the long boom and clamping plate will automatically clamp together under the pull of the steel wire rope 14 and the weight of the curbstone. The gripping time is about 1-2 minutes. Then, move it above the installation area, operate the hand support to adjust the height, and use the fine-tuning device to adjust the posture of the curbstone. The adjustment process takes 2 minutes.

[0071] Finally, the curbstone was precisely placed in the preset position and plastered to fix it, completing the installation. Each step was closely connected, efficient and orderly.

[0072] When transporting and grabbing curb stones, strong winds or steep slopes often cause the clamping mechanism to sway, resulting in the curb stone falling off or becoming unstable. This mechanism reduces the swaying range of the clamping mechanism through connecting rods, and the presence of guide rails does not affect the vertical movement of the clamping mechanism.

[0073] The beneficial effects of this solution are as follows: 1. This process has significant advantages. Firstly, it is easy to operate; workers can become proficient after simple training, lowering the technical threshold. Secondly, it is inexpensive; the device structure is simple, materials are common, and manufacturing and maintenance costs are low, approximately 1000-2000 yuan, effectively controlling project costs. Thirdly, it is highly efficient and fast; close coordination between each stage reduces handling and installation time, increasing construction efficiency by 30%-50% compared to traditional methods. Fourthly, it has high precision; the fine-tuning device can precisely control the position and posture of the curbstone, ensuring installation quality, making the road edge neat and aesthetically pleasing, reducing later maintenance costs, and improving the overall quality and service life of the road, making it highly valuable in the field of road engineering. 2. The anti-sway mechanism prevents the clamping mechanism from swaying in strong winds or steep slopes, thus preventing curbstone detachment or unstable clamping. 3. This solution simplifies the gripping steps; the curbstone's own weight causes the long rod and clamping plate to automatically clamp and release, improving gripping efficiency.

[0074] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
