[0002] Cement poles are a kind of infrastructure composed of cement and steel bars, mainly used for supporting power lines, communication lines, etc., which are widely used in urban and rural areas, and can stably bear the weight of the lines and the impact of the wind. In addition, cement poles have many other uses, such as erecting dustproof nets, serving as monitoring columns, and equipment support columns in substations, etc. After the cement poles are manufactured, they will be transported to the designated installation site by trucks according to customer requirements. After the truck arrives, in order to ensure that the movement of the truck is not limited by the road surface of the installation site, the transport personnel will choose a spacious and suitable open space to unload the cement poles. However, cement poles are usually long and heavy, and are prone to rolling during unloading and handling, which may cause safety hazards.

[0007] 2. The cement pole carrying anti-rolling loading and unloading frame is provided with an anti-rolling storage device. The V-shaped rubber pad and the V-shaped bracket form a V-shaped groove area to store the cement pole in a bottom supporting mode, preventing the cement pole from rolling to the sides when the top cement pole pushes the bottom cement pole to the sides, causing safety hazards.

The limiting square plate moving with the square sleeve simultaneously covers and protects the top area of the surface of the threaded long rod that is not wrapped by the wave-shaped ring piece. When the wave-shaped ring piece is compressed by the square sleeve, the wrapping area continuously decreases, causing the area on the surface of the threaded long rod away from the wave-shaped ring piece on the side of the square sleeve to easily accumulate ash particles and be difficult to handle. The two inclined push plates fix the cement pole from the two sides of the V-shaped rubber pad, preventing the cement pole stored inside the V-shaped rubber pad from sliding out of the V-shaped groove area of the V-shaped rubber pad and causing safety hazards. The electromagnetic lock is arranged on the top of the inclined push plate to intercept and lock the top area of the V-shaped rubber pad, preventing the cement pole placed inside the V-shaped rubber pad from being affected by external forces and causing safety hazards.

Multiple sets of return springs 5102 and limiting rods 5103 are evenly distributed on the inner wall of the hollow air cushion 5101 to stabilize its shape. When the inclined push plate 509 moves with the square sleeve 505, causing the hollow air cushion 5101 to gradually move away from the cement pole, the hollow air cushion 5101 loses its compressive force. At this time, the return spring 5102 pushes the hollow air cushion 5101 to collide and recover through its extension force. By installing multiple return springs 5102 inside the hollow air cushion 5101, the hollow air cushion 5101, having lost its compressive force, undergoes assisted expansion and recovery.

[0015] In operation, the cement poles are placed in the anti-roll storage device 4 using a crane. Once the cement poles are completely within the anti-roll storage device 4, the internal pressure fixing device 5 secures them from both sides using an internal pressure locking mechanism. After securing the cement poles, the tripod 1 can be pushed to move the casters 2 to the destination. The crane then places the cement poles inside the V-shaped rubber pad 403 at the top of the tripod 1. Simultaneously, the V-shaped bracket 401 and bottom connecting rod 402 on the outer side of the V-shaped rubber pad 403 support its bottom. The V-shaped groove area formed by the V-shaped rubber pad 403 and the V-shaped bracket 401 provides a bottom-supported storage for the cement poles. The anti-slip V-shaped rubber pad 403, located inside the V-shaped bracket 401, directly contacts the cement poles. A rectangular elongated hole 404 is made inside the V-shaped rubber pad 403, penetrating the V-shaped bracket 401, to facilitate the discharge of mortar particles adhering to the cement pole. An inclined fixing plate 405 is installed on the outside of the V-shaped bracket 401 to reinforce the V-shaped bracket 401 with the rectangular elongated hole 404. After the cement pole is placed inside the V-shaped rubber pad 403, the rocker handle 504 is manually turned to rotate the threaded rod 503. When the threaded rod 503 rotates, it moves the square sleeve 505, which is threadedly engaged with it and limited by the top limiting square plate 507. The square sleeve 505, threadedly engaged with the threaded rod 503, moves towards the corrugated ring 506, causing the top limiting square plate 507, the top inclined plate 508, the inclined push plate 509, and the elastic compression mechanism to move. As the mechanism 510 moves together, the square sleeve 505 pushes and compresses the corrugated ring 506 as it moves towards the corrugated ring 506. The corrugated ring 506, positioned between the two square sleeves 505, constantly wraps and protects the area of ​​the threaded rod 503 located between the two square sleeves 505. Simultaneously, the limiting square plate 507, moving with the square sleeves 505, covers and protects the top area of ​​the threaded rod 503 not covered by the corrugated ring 506. As the inclined push plate 509 moves with the square sleeves 505, it drives the elastic compression mechanism 510 on one side to elastically compress and contact the cement rod inside the V-shaped rubber pad 403. The two inclined push plates 509 internally press and fix the cement rod from both sides of the V-shaped rubber pad 403. After the inclined push plate 509 internally presses and fixes the cement rod inside the V-shaped rubber pad 403, the electric push rod 512 pushes the two electromagnetic locks 513 to move towards each other until they contact each other, thereby sealing the top of the V-shaped rubber pad 403. By setting the electromagnetic locks 513 on the top of the inclined push plate 509, the top area of ​​the V-shaped rubber pad 403 is intercepted and sealed. When the inclined push plate 509 moves with the square sleeve plate 505, it drives the hollow air cushion 5101 on one side to move together. When the hollow air cushion 5101 moves with the inclined push plate 509 and contacts the cement rod inside the V-shaped rubber pad 403, it is squeezed and compressed by the pushing force, which compresses the internal return spring 5102 and pushes the internal limit rod 5103 to move towards the inclined push plate 509.The cement rod is elastically contacted by setting the elastically compressible hollow air cushion 5101 on one side of the inclined push plate 509, the reset spring 5102 is internally supported and shape stabilized by setting the limiting through rod 5103 penetrating the inclined push plate 509 at the position of the inner wall of the hollow air cushion 5101 inside the reset spring 5102, the hollow air cushion 5101 is shape stabilized by setting multiple groups of reset springs 5102 and limiting through rods 5103 evenly distributed on the inner wall of the hollow air cushion 5101, when the hollow air cushion 5101 gradually moves away from the cement rod along with the square sleeve plate 505, the hollow air cushion 5101 loses the extrusion force, at this time the reset spring 5102 pushes the hollow air cushion 5101 to collide and restore by the extension force, multiple reset springs 5102 are set inside the hollow air cushion 5101 to assist the hollow air cushion 5101 losing the extrusion force to expand and restore.
