[0012] This utility model provides a transportation and installation device for roadbed curbs, including a mobile frame and clamping claws disposed at the front end of the mobile frame for clamping the roadbed curbs. The mobile frame includes a travel wheel 1, a main shaft 2, a main frame 3, a foot support 4, a handle 5, a crossbar 6, and a structural reinforcing rod 7. The travel wheel 1 is rotatably connected to both ends of the main shaft 2 via bearings and can rotate flexibly. The main frame 3 is inclinedly mounted on the main shaft 2 and the handle 5 is mounted on its upper end. The foot support 4 is fixedly welded to the main frame 3. The crossbar 6 is fixedly mounted at the center of the main frame 3, and the structural reinforcing rod 7 is fixedly connected between the crossbar 6 and the main frame 3. It also includes an anti-sway mechanism disposed on the crossbar 6 to prevent the roadbed curbs from shaking and an opening mechanism for opening the clamping claws. The upper handle 5 is for the operator to hold, and the lower foot support 4 can be balanced by applying pressure by stepping on it. The structural reinforcing rod 7 enhances the connection strength between the crossbar 6 and the main frame 3.

[0013] The clamping claw includes two swing arms 8, a first pin 9, a second pin 10, a first connector 11, and a second connector 12. The two swing arms 8 are symmetrically arranged and their upper ends are hinged together by the first pin 9. The first pin 9 is horizontally arranged and fixed to the front end of the crossbar 6 by a suspension rope. The first connector 11 and the second connector 12 intersect each other and are hinged together by the second pin. The upper ends of the first connector 11 and the second connector 12 are respectively hinged to the lower ends of the two swing arms 8. The lower ends of the first connector 11 and the second connector 12 form clamping parts for clamping both sides of the roadbed curb. Each clamping part is provided with rubber anti-slip parts, and the anti-slip parts on the first connector 11 and the second connector 12 are arranged opposite to each other. The clamping claw consists of two symmetrical swing arms and a first connector and a second connector that are cross-hinged. The upper end of the swing arm 8 is hinged together by the first pin 9, and the lower end is respectively hinged to the upper end of the first connector 11 and the second connector 12. The intersection of the first connector 11 and the second connector 12 is hinged together by the second pin 10, and the lower end forms the clamping part. When there is no external force applied to the clamping part, the cross-connecting parts will naturally close under the action of the weight of the curb or the self-resetting force of the connector, so that the clamping part is tightly attached to both sides of the curb, thus achieving clamping. The opening mechanism includes two fixed pulleys 16, two pull ropes 18, and vertical rods 13 symmetrically arranged on both sides of the horizontal rod 6. Each vertical rod 13 is equipped with an arc-shaped slide rail 14 and a straight groove 15. A first pin 9 is movably installed between the arc-shaped slide rails 14 of the two vertical rods. A second pin 10 is slidably connected within the two straight grooves 15 and extends to the outside of the vertical rods 13 at both ends. The two fixed pulleys 16 are respectively installed on the outer walls of the two vertical rods 13. A guide cylinder 17 is provided at the top of the horizontal rod 6. One end of each of the two pull ropes 18 has a pull ring 19, and the other ends pass through the inner wall of the guide cylinder 17 and are respectively wound around the two fixed pulleys 16 and connected to the second pin 18. The two ends of 0 are fixedly connected; the opening mechanism realizes the opening of the clamping claw through the cooperation of the pull rope 18, the fixed pulley 16, the pin and the slide groove. The straight slide groove 15 on the vertical rod 13 restricts the movement trajectory of the second pin 10, and the arc-shaped slide rail 14 restricts the range of motion of the first pin 9; when the pull ring 19 is pulled, the pull rope 18 changes the direction of the force through the fixed pulley 16, driving the second pin 10 to slide upward along the straight slide groove 15, forcing the crossed first and second connecting parts to rotate around the second pin 10, and its lower clamping part opens. When the pull ring 19 is released, the second pin 10 moves downward along the slide groove under the action of gravity or the restoring force of the connecting parts, and the clamping part closes.

[0014] The anti-sway mechanism includes two support members 20 symmetrically arranged on both sides of the crossbar 6. Each support member 20 includes an integrally formed vertical part and an inclined part located at the bottom of the vertical part. A spring telescopic rod 21 is horizontally arranged at the end of the inclined part, and a pressure plate 22 is installed on the movable section of the spring telescopic rod 21. The anti-sway mechanism of the curb is achieved by the elastic pressure of the spring telescopic rod 21.

[0015] The specific operation process of this utility model is as follows: The operator checks the status of each component of the device, pushes the device to the side of the curb to be transported by gripping lever 5, adjusts the angle of the main frame 3 so that the clamping claw is aligned with the top of the curb, and the foot support 4 is in contact with the ground to keep the device stable. The operator pulls the pull ring 19, and the pull rope 18 drives the second pin 10 to slide upward along the straight slide groove 15 of the vertical rod 13 after passing through the guide cylinder 17 and the fixed pulley 16. When the second pin 10 moves upward, the first connecting piece 11 and the second connecting piece 12 rotate around the second pin 10, and the clamping part at its lower end opens. At this time, the first pin 9 slides adaptively in the arc-shaped slide rail 14 with the swing rod 8, cooperating with the opening action of the clamping claw.

[0016] Adjust the position of the device so that the open clamping part is aligned with both sides of the curb. Slowly release the pull ring 19. Under the action of the weight of the curb and the reset force of the connecting parts, the second pin 10 moves down along the straight slide groove 15. The clamping parts of the first and second connecting parts gradually close and clamp tightly against both sides of the curb. At the same time, the spring telescopic rod 21 of the anti-sway mechanism is squeezed and contracted by the curb. The pressure plate 22 of its movable section is tightly against both sides of the curb under the action of elasticity, forming a stable limit.

[0017] The operator holds the handle 5 and pushes the device to move via the travel wheel 1. During transportation, the crossbar 6 is in an inclined state, and the spring telescopic rod 21 of the anti-sway mechanism can continuously provide elastic pressure. One side of the curb is always in close contact with the pressure plate 22 to counteract the shaking caused by road bumps or inertia. If the road surface is uneven, the device can be balanced by stepping on the foot pedal bracket 4 to ensure the stability of the curb.

[0018] After the device is moved to the installation position, the operator pulls the pull ring 19 again to repeat the opening action of the clamping stage: the pull rope 18 drives the second pin 10 to move upward, and the clamping part opens; the height and angle of the device are slowly adjusted so that the curb is accurately placed in the installation position; the pull ring 19 is released, and the clamping part closes naturally. At this time, the curb has been placed in place, and the clamping part separates from the curb; finally, the device is pushed away from the installation point to complete one transportation and installation operation.
