Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a curbstone transport vehicle. Background Technology

[0002] In municipal road construction, urban renewal and landscaping projects, curb stones are key components that define road surfaces, sidewalks and green belts. Their installation is an important part of the project. Curb stones are usually made of materials such as concrete and stone. The weight of a single stone is generally between 30 and 80 kg, and some large stone curb stones can weigh more than 100 kg. They also have a regular rectangular structure and a certain degree of brittleness.

[0003] Because curb stones are large and heavy, using large machinery such as cranes and forklifts for short-distance transport is inflexible and inefficient. Therefore, the installation and short-distance transportation of curb stones currently rely on manual labor. However, due to the large size and weight of the curb stones, multiple people are needed to move them, which is time-consuming, labor-intensive, and prone to causing injuries to hands and feet, resulting in poor safety. To address these issues, we propose a curb stone transport vehicle. Summary of the Invention

[0031] Example 1

[0032] Please see Figure 1-6 This utility model shows a curbstone transport vehicle, including a support arm 1 and a frame 12. The bottom of the frame 12 is provided with wheels. The support arm 1 is installed on the frame 12 through a support frame 6. One end of the support arm 1 is equipped with a handle 4, and the other end of the support arm 1 is suspended by a lifting clamp 9.

[0033] The frame 12 is the load-bearing foundation of the equipment, used to support the overall weight, while the wheels at the bottom provide the equipment with mobility. The support arm 1 is the core of force transmission and control. One end is connected to the handle 4 for the operator to apply force to control the direction, and the other end is suspended from the lifting clamp 9 to carry the curb stone. Through the force transmission path of "handle-support arm-clamp", heavy objects can be easily and effortlessly moved by 1-2 people.

[0034] The wheel 13 is preferably a swivel wheel with a braking mechanism and is equipped with a braking mechanism.

[0035] The working principle of this utility model is as follows: First, the worker suspends the hoisting clamp 9 at the right end of the support arm 1. Then, the worker can hold the handle 4 and push the frame 12 to move. When the hoisting clamp 9 moves above the curbstone, the worker can gently move the handle 4 upwards. Then, the hoisting clamp 9 will fall above the curbstone. Then, the worker can move the handle 4 downwards, and the hoisting clamp 9 can firmly clamp and lift the curbstone. Then, the worker can push the device to move by holding the handle 4.

[0036] Example 2

[0037] In this embodiment, the handle 4 is adjustablely connected to the support arm 1 via the movable plate 3. The support arm 1 has a groove 14 for accommodating the movable plate 3. The surface of the movable plate 3 has a set of first adjustment holes 13 arranged at equal intervals. The support arm 1 is fixedly installed with a limiting component 2, which is used to limit the movement of the movable plate 3 within the groove 14.

[0038] The slide 14 is an adjustment track, which is opened at one end of the support arm 1 near the handle 4 and is set along the length of the support arm 1. Its cross-section can be configured as a rectangular groove, and its size is adapted to the moving plate 3 to ensure that the moving plate can slide smoothly along the groove and avoid deviation.

[0039] The movable plate 3 is the connecting medium between the handle 4 and the support arm 1. The movable plate 3 is a rectangular metal plate that is adapted to the slide groove 14. One end of it is fixed to the handle 4 by welding, bolts or other means, and the other end extends into the slide groove 14. The position of the handle 4 along the length of the support arm can be adjusted by sliding, so as to adapt to the force application posture of operators of different heights, or the need to adjust the torque when different working scenarios, such as different curb stone lifting heights and weights, are required.

[0040] The limiting component 2 is used to prevent the moving plate 3 from sliding, especially to prevent the moving plate 3 from becoming loose during the handling of curb stones, thereby ensuring the stability of the force applied by the operator and reducing safety risks. It can be fixed by bolts in the existing technology, or by the following methods.

[0041] Specifically, the limiting component 2 includes a limiting spring 202, a lever 201 is fixedly installed on the top of the limiting spring 202, and a limiting pin 203 is fixedly installed on the bottom surface of the lever 201. The bottom ends of the limiting pins 203 pass through the first limiting hole 17 and extend into the interior of the slide groove 14. The limiting pins 203 can engage with the first adjusting hole 13 to restrict the movement of the moving plate 3.

[0042] There are at least two ways in which the limiting spring 202 and the limiting pin 203 can be matched:

[0043] Method 1: The limiting pin 203 can rotate inside the first limiting hole 17. The distance between the outer surface of the limiting pin 203 and the central axis is different. When it rotates to a certain angle, the moving plate 3 can be released from the limitation of the limiting pin 203 and slide. When the moving plate 3 is adjusted to a suitable position, the limiting pin 203 is released. Under the deformation force of the limiting spring 202, the limiting pin 203 returns to engagement, thereby restricting the movement of the moving plate 3.

[0044] Method 2: The limiting pin 203 can be inserted and removed relative to the first limiting hole 17. When the limiting pin 203 is pulled out, the moving plate 3 can slide away from the limitation of the limiting pin 203. When the moving plate 3 is adjusted to a suitable position, the limiting pin 203 is released. Under the deformation force of the limiting spring 202, the limiting pin 203 returns to the inserted state, thereby restricting the movement of the moving plate 3.

[0045] Example 3

[0046] In this embodiment, as Figure 2-3As shown, a self-weight lifting clamp 9 is used, which is a clamp that can rely on the weight of the curb stone itself to achieve clamping. The lifting clamp 9 includes a jaw body 91, a movable rod 92, two clamping arms 93, and two linkage rods 94.

[0047] Two clamping arms 93 are set on both sides of the gripper body 91. One end of the movable rod 92 is connected to the lifting ring, and the other end of the movable rod 92 passes through the gripper body 91 and is hinged to one end of the two clamping arms 93. One end of the two linkage rods 94 is hinged to the gripper body 91, and the other end of the two linkage rods 94 is respectively hinged to the middle section of the two clamping arms 93.

[0048] The principle of the lifting clamp 9 is as follows: when gripping the curb stone, the movable rod 94 moves upward and drives one end of the two clamping arms 93 that are hinged to it to rise synchronously. Since the middle section of the clamping arm 93 is hinged to the two linkage rods 94, the two clamping arms 93 will move closer to each other and retract inward with the connection point of the clamping arm 93 and the linkage rod 94 as the fulcrum, so as to clamp and fix the curb stone.

[0049] When the curbstone is released, the movable rod 94 moves downward, and the downward movement of the movable rod 94 drives one end of the two clamping arms 93 that are hinged to it to open and close synchronously. The two clamping arms 93 move away from each other and open, thereby releasing the clamp.

[0050] Example 4

[0051] In this embodiment, a first reinforcing rod 5 and a second reinforcing rod 7 are fixedly installed on both sides of the support frame 6, respectively. The top end of the first reinforcing rod 5 is fixedly installed to the bottom surface of the support arm 1, and the top end of the second reinforcing rod 7 is fixedly installed to the bottom surface of the support arm 1. The long reinforcing rod 5 and the short reinforcing rod 7 respectively reinforce the left and right ends of the support arm 1, which can prevent the support arm 1 from deforming.

[0052] Example 5

[0053] In this embodiment, the support frame 6 is movably connected to the vehicle frame 12 via a height adjustment mechanism, which is used to adjust the height of the support frame 6 relative to the vehicle frame 12. The height adjustment mechanism can be a structure found in the prior art, or it can use the following structure.

[0054] Specifically, the top of the frame 12 is provided with a limiting frame 11, the outer surface of the support frame 6 is slidably connected to the inner wall of the limiting frame 11, the outer surface of the limiting frame 11 is provided with a second limiting hole 18, and the outer surface of the support frame 6 is provided with a set of equally spaced second adjusting holes 16. It also includes bolts 10, which pass through the second limiting hole 18 and extend to the outside of the limiting frame 11 before being fixed by the bolts 10. The bolts 10 can engage with the second adjusting holes 16 to restrict the movement of the support frame 6.

[0055] Example 6

[0056] In this embodiment, a limiting rod 8 is fixedly installed on the support arm 1 to prevent the lifting clamp 9 from falling. Multiple limiting rods 8 are configured to achieve more adjustments in distance and torque.
