Description

Technical Field

[0001] The utility model belongs to the technical field of road construction auxiliary tools, in particular to a curbstone transporting and clamping device. Background Art

[0002] With the acceleration of urbanization, road construction and maintenance have become an important part of urban infrastructure construction. Curbstones are the definition and protection facilities of road edges, and their installation quality directly affects the overall appearance and driving safety of the road.

[0003] In the process of transporting curbstones, the role of clamping devices is crucial. They not only ensure the smooth transportation, but also protect the curbstones from damage during movement. However, the clamping devices widely used in the market are mostly two-point clamping designs. Although this design meets the basic transportation needs to a certain extent, during the clamping process, the clamping force is often mainly concentrated on these two points, while other parts of the curbstone may be subject to less or almost no clamping force. The uneven distribution of clamping force is particularly obvious when transporting curbstones with heavy weight, irregular shape or fragile surface material. In extreme cases, such as bumps, vibrations or sudden acceleration and deceleration during transportation, the two-point clamping device may not be able to effectively disperse and balance the clamping force, resulting in the clamping force being relatively concentrated in certain areas. The concentrated force may cause excessive pressure on the local part of the curbstone, and even cause damage, cracks or surface wear. Therefore, it needs to be improved and optimized. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a curbstone handling and clamping device, which solves the problem of uneven clamping force.

[0007] Preferably, the two opposite clamping rods are provided with mounting grooves on their adjacent sides, and two sliders are provided in the middle of the two opposite clamping rods.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, the utility model provides a curbstone handling and clamping device, comprising a cylinder 1, a mounting block 2 fixedly mounted at the bottom of the cylinder 1, two clamping grooves 3 provided at the bottom of the mounting block 2, and clamping mechanisms respectively provided inside the two clamping grooves 3;

[0025] The clamping mechanism includes two round rods 8 rotatably installed in the clamping groove 3, and two clamping rods 1 9 are fixedly sleeved on the outer walls of the two round rods 8. The bottoms of the two clamping rods 1 9 are respectively hingedly installed with clamping rods 2 10.

[0026] Through the precise cooperation of the two clamping rods 1 9 and the clamping rod 2 10, a more stable clamping system is constructed. The clamping rod 1 9 moves flexibly following the rotation of the rotating rod 6. This linkage mechanism then drives the clamping rod 2 10 and the clamping plate 15 fixed thereon to accurately approach or move away from the curb. The clamping plate 15, as the interface in direct contact with the curb, successfully disperses the clamping force evenly and widely to the outer wall of the curb with its large contact area, effectively avoiding the problems of excessive local pressure and curb damage that may be caused by single-point concentrated clamping. Compared with the traditional single-point clamping method, this multi-point dispersed clamping design significantly improves the balance and safety of clamping, reduces the risk of damage to the curb during clamping, and realizes both stable and delicate clamping and release operations of the curb.

[0027] like Figure 5As shown, the adjacent sides of the two opposing clamping rods 10 are respectively provided with mounting grooves 12, and the middle of the two opposing clamping rods 10 are respectively provided with two sliders 13, and the corresponding sliders 13 are elastically connected to the corresponding mounting grooves 12 through spring damping rod assemblies 14, and the outer walls of the two sliders 13 on the same side are respectively fixedly installed with clamping plates 15, and the corresponding sliders 13 are slidably connected to the corresponding mounting grooves 12.

[0028] By passing the spring damping rod assembly 14 between the slider 13 and the mounting groove 12, the elastic force of the spring provides stable support for the slider 13, so that during transportation, even if it encounters bumps or vibrations, the slider 13 can maintain a relatively stable position, thereby ensuring that the clamping plate 15 stably clamps the curbstone, preventing the curbstone from slipping or loosening during transportation. The sliding connection between the slider 13 and the mounting groove 12 also gives the clamping device a certain degree of adaptability. Since the slider 13 can slide freely in the mounting groove 12, the clamping device can automatically adjust according to different curbstone sizes to ensure the stability and reliability of the clamping.

[0029] like Figure 6 As shown, a motor protection shell 4 is fixedly mounted on the outer wall of the mounting block 2, a motor 5 is fixedly mounted on the inner wall of the motor protection shell 4, a rotating rod 6 is fixedly mounted on the output shaft of the motor 5, and the end of the rotating rod 6 away from the motor 5 passes through the two clamping grooves 3 and is rotatably connected to the inner wall of one of the clamping grooves 3.

[0030] The power is directly transmitted to the rotating rod 6 through the output shaft of the motor 5. By controlling the forward and reverse rotation of the motor, the opening and closing action of the clamping rod or the clamping plate can be easily realized. The design of the rotating rod 6 passing through the two clamping grooves 3 enables the clamping device to flexibly adapt to the needs of handling curbs of different sizes and shapes, thereby improving the versatility and adaptability of the equipment.

[0031] like Figure 4 As shown, tooth grooves 91 are respectively formed on the outer walls of the four clamping rods 9, and two tooth grooves 91 close to each other are meshed.

[0032] When the clamping rods 9 are brought close to each other during operation to clamp the curb, the tooth grooves 91 on their outer walls will engage with each other, forming a self-locking mechanism, which not only enhances the stability of the clamping, but also ensures that even if vibration or external force impact is encountered during transportation, the clamping device can maintain a stable clamping state to prevent the curb from slipping or loosening.

[0033] like Figure 4 As shown, two gears 7 are fixedly sleeved on the outer wall of the rotating rod 6 , and both gears 7 are engaged with adjacent tooth grooves 91 .

[0034] Through the engagement of the gear 7 and the tooth groove 91, the rotational movement of the rotating rod 6 can be accurately converted into the opening and closing action of the clamping mechanism, ensuring the synchronization and accuracy of the clamping action, and avoiding the problems of unstable clamping or curb slipping caused by transmission errors.

[0035] like Figure 1 As shown, two connecting rods 11 are hingedly installed inside the two clamping grooves 3, and the bottoms of the four connecting rods 11 are hingedly connected to the adjacent clamping rods 10.

[0036] Through the hinged structure of the connecting rod 11 and mechanical drive, the clamping rod 2 10 can be moved synchronously and evenly, so that the two clamping plates can clamp the curb more tightly and stably. Even if there are bumps or vibrations during transportation, they can maintain a stable clamping state to ensure that the curb will not fall off or shake.

[0037] like Figure 1 As shown, an anti-slip groove 16 is respectively formed on one side of the two clamping plates 15 that are close to each other, and the area of ​​the anti-slip groove 16 is consistent with the area of ​​the clamping plates 15 .

[0038] The design of the anti-slip groove 16 significantly improves the friction between the clamping plate and the curbstone, ensuring that during the transportation process, no matter how the road conditions change or whether it encounters bumps, tilts, etc., the curbstone can be firmly clamped and is not easy to slip or shake, thereby greatly improving the safety and stability of the transportation operation.

[0039] The working principle and use process of this utility model:

[0040] Start the motor 5 in the motor protection shell 4, and the output shaft of the motor 5 begins to rotate to drive the rotating rod 6 to rotate. The rotation of the rotating rod 6 is transmitted to the tooth groove 91 on the clamping rod 9 through the two gears 7 fixed on its outer wall. The engagement of the gear 7 and the tooth groove 91 ensures that the clamping rod 9 can rotate accurately with the rotation of the rotating rod 6. The corresponding two clamping rods 9 begin to move synchronously under the guidance of the tooth groove 91 and the gear 7. Since the bottom of the clamping rod 9 is respectively hingedly installed with the clamping rod 2 10, the movement of the clamping rod 19 will drive the clamping rod 2 10 to move accordingly. As the clamping rod 2 10 moves, the slider 13 thereon slides in the installation groove 12 and is kept stable by the elastic connection of the spring damping rod assembly 14. The movement of the slider 13 drives the clamping plate 15 to approach the curb until the clamping plate 15 is in close contact with the curb. The clamping plate 15 is held in place by the With its larger contact area, the clamping force is evenly and widely dispersed to the outer wall of the curb. The design of the anti-skid groove 16 increases the friction between the clamping plate 15 and the curb, ensuring the stability of the clamping. The hinged structure of the connecting rod 11 ensures that the two clamping plates 15 can move synchronously and evenly, further enhancing the stability of the clamping. Under the continuous drive of the motor 5, the clamping device maintains a firm clamp on the curb and starts the transportation process. During the transportation process, the adaptive ability and anti-skid design of the clamping device ensure that the curb will not slip or be damaged during transportation. When the curb needs to be placed in the specified position, the motor 5 is controlled to reverse and the rotating rod 6 is rotated in the opposite direction. The reverse rotation of the rotating rod 6 drives the clamping rod 1 9 and the clamping rod 2 10 to move in the opposite direction through the engagement of the gear 7 and the tooth groove 91, and the clamping plate 15 then moves away from the curb to complete the release action.
