Description

Technical Field

[0001] This utility model relates to the field of agricultural power grid construction technology, and in particular to a heavy pole transportation device. Background Technology

[0002] With the development of electricity, utility poles are an essential component and are in high demand. In many areas where large vehicles cannot access, the transportation work is mostly done manually, requiring a large number of personnel to move the poles to the foundation pit, which is time-consuming and labor-intensive.

[0003] Existing utility pole transfer equipment, in order to ensure relative stability, has changed from the traditional one set of wheels to two sets, guaranteeing transport stability. At the same time, to improve steering flexibility during movement, one set of wheels is a swivel caster. In this type of transfer equipment, curved clamps are typically used to restrain the utility poles. However, this means that the poles are not effectively secured when placed on the equipment for transport, making them prone to relative slippage or rolling during transit. This not only affects the stability of the transfer operation but also causes the utility poles to exert a large bending moment on the curved clamps, leading to deformation and damage to the components that drive the clamps.

[0038] The lead screw 28 assembly includes a lead screw 28, an angular contact bearing housing 27, a thrust bearing 15, an angular contact bearing 18, a thrust bearing housing 26, and a bearing spacer 17. The thrust bearing housing 26 is mounted on the lifting bracket 13, the thrust bearing 15 is mounted on the thrust bearing housing 26, and the angular contact bearing housing 27 is mounted on the thrust bearing housing 26.

The bearing spacer 17 is sleeved on the lead screw 28 and is located between the thrust bearing 15 and the angular contact bearing 18.

[0039] The jaw clamping mechanism 4 includes a first spring 31, a first jaw 30, a second jaw 29, a second spring 32, a jaw first rotating component 35, and a jaw second rotating component 36. The first jaw 30 and the second jaw 29 are respectively hinged to the lifting bracket 13 through the jaw first rotating component 35 and the jaw second rotating component 36.

The second jaw 29 and the second jaw rotating shaft 47 are rotatably connected.

[0041] Working principle: The drive mechanism 5 rotates the wheel set, adjusts the position of the jaw clamping mechanism 4 so that the extension direction of the heavy rod 6 is towards the area between the first jaw 30 and the second jaw 29, and continues to drive the wheel set to move, so that the heavy rod 6 passes through the area between the first jaw 30 and the second jaw 29. After reaching the clamping position, the drive wheel set is stopped, and the motor 14 is started. The motor 14 drives the lead screw 28 to rotate, and the rotation of the lead screw 28 drives the lifting nut 23 to move axially along the lead screw 28 (restricted by the first slider 21 and the second slider 22). The lifting nut 23 drives the lifting nut seat 24 to move. The first slider 21 and the second slider 22 restrict the movement of the lifting nut seat 24 along the extension direction of the first guide rail 19 and the second guide rail 20. At the same time as the lifting nut seat 24 moves, the first jaw 30 and the second jaw 29 are driven, so that the first jaw 30 and the second jaw 29 move together. 9 rotates around the first jaw rotation axis 50 and the second jaw rotation axis 29 respectively. The ends of the first jaw 30 and the second jaw 29 away from the lifting wire seat 24 move closer to each other, completing the initial clamping of the heavy rod 6. The motor 14 continues to drive the lead screw 28 to rotate until the first jaw 30 and the second jaw 29 lift the heavy rod 6, and then stops running, completing the clamping of the heavy rod 6. The wheel set (walking mechanism 5) is driven to walk again and transport it to the corresponding position. During the transportation process, the heavy rod 6 will swing due to gravity. This application utilizes the swing part design of the rotating mechanism 1. When the heavy rod 6 swings, the lifting bracket 13 will also swing. The swing of the lifting bracket 13 will drive the rotating bracket 8 to swing around the rotation axis, so that the moving mechanism 2 will not be subjected to bending moment, protecting the entire transportation system from damage by the heavy rod 6 and improving transportation efficiency.
