Description

Technical Field

[0001] This invention relates to the field of power steel pipe pole transportation technology, specifically a support device for transporting power steel pipe poles. Background Technology

[0002] Power steel pipe poles are the preferred choice for power transmission construction because they occupy a small area, generally about 1 / 3 the size of a self-supporting iron tower. Power steel poles are made of steel materials such as polygonal steel pipes and round steel pipes, and are treated with hot-dip galvanizing or hot-spray zinc (and zinc alloy) coating for corrosion protection. They are mainly used for power line erection.

[0003] Existing power steel pipe poles are usually transported by trucks. After being placed in the truck bed, the poles are secured with chains, ropes, and other tools. However, this method of securing them is not very tight. When the truck travels on bumpy roads, the shaking of the truck bed causes the secured power steel pipe poles to loosen, resulting in them colliding with each other or hitting the truck bed, causing damage or even falling off, thus affecting the subsequent transportation efficiency.

[0004] Chinese patent CN110834800A discloses an auxiliary mechanism for transporting power steel pipe poles. The device includes a base plate, a supporting base frame, a first side frame, a second side frame, a first inner frame, a first horizontal bar, a third side frame, a fourth side frame, a second inner frame, a second horizontal bar, etc. While this patent achieves a more secure clamping effect by installing a first clamping structure and a second clamping structure on the front and rear sides of the upper end of the base plate, simultaneously clamping and fixing the power steel pipe pole from both ends of the base plate, thus ensuring stability during transport and facilitating the transport of the power steel pipe pole, it still has the following drawbacks: the contact area with the power steel pipe pole is small, and its clamping effect needs improvement; furthermore, the user needs to frequently rotate the handwheel to complete the clamping action, making the operation relatively complex.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0031] Please see Figures 1-7 The present invention provides a support device for transporting power steel pipe poles, including a base plate 1, and a support assembly 2, a side clamping assembly 3, an upper clamping assembly 4 and a linkage mechanism 5 installed on the base plate 1; these are the main components of the support device.

[0032] The base plate 1 has symmetrically arranged columns 11 at both ends of its top, and side plates 12 are provided at both ends of the base plate 1. The support assembly 2 includes a support member 21 and mounting seats 22 symmetrically arranged at both ends of the support member 21. The two mounting seats 22 are respectively mounted on the two columns 11, and the support member 21 has a V-shaped groove 23V. In use, two support devices can be placed in the transport vehicle according to the length of the electric steel pipe pole. The support members 21 of the two support devices support and support the two ends of the electric steel pipe pole respectively. After the electric steel pipe pole is placed on the support member 21, its two ends are located in the center of the V-shaped groove 23V of the support member 21. The V-shaped groove 23V abuts against the outer wall to restrict the rolling of the electric steel pipe pole and ensure its transport stability.

[0033] The side clamping assembly 3 is located on one side of the supporting assembly 2. The side clamping assembly 3 includes clamping parts 31 symmetrically arranged at both ends of the top of the base plate 1. The clamping parts 31 have a vertical clamping surface on opposite sides. The bottom end of the clamping part 31 is provided with a sliding seat that slides with the base plate 1. The sliding seat can only slide along the length of the base plate 1. When the power steel pipe pole is placed on the supporting assembly 21, the sliding seats of the two clamping parts 31 can slide relative to each other on the top of the base plate 1, thereby clamping the side of the power steel pipe pole through the two clamping parts 31 to ensure its transportation stability.

[0034] The upper clamping assembly 4 includes clamping rods 42 symmetrically mounted on the mounting base 22 directly above the supporting member 21 via a rotating shaft 41. The clamping rods 42 can rotate in the vertical plane around the rotating shaft 41. When the two clamping parts 31 clamp the side of the power steel pipe pole, the two clamping rods 42 can rotate around their rotating shaft 41 and form symmetry with the V-shaped groove 23V of the supporting member 21. The V-shaped groove 23V cooperates with the power steel pipe pole to form a clamp on the upper part of the power steel pipe pole, ensuring its transportation stability.

[0035] The present invention, through the cooperation of the supporting component 2, the side clamping component 3 and the upper clamping component 4, can adapt to the six-point clamping operation of power steel pipe poles of different sizes, ensuring the stability of their transportation.

[0036] To quickly complete the clamping work at six points before transporting the power steel pipe pole, in this invention, the mounting base 22 slides with the corresponding column 11 and can only slide in the vertical direction; a torsion spring (not shown) is provided on the rotating shaft 41; the linkage mechanism 5 includes a return spring 51 for providing elastic damping when the mounting base 22 slides downward, and hydraulic transmission components symmetrically arranged at both ends of the base plate 1. The hydraulic transmission components include a first hydraulic telescopic part 52, a second hydraulic telescopic part 53, a third hydraulic telescopic part 54, and a fourth hydraulic telescopic part 55. The fixed end of the first hydraulic telescopic part 52 is fixedly connected to the base plate 1, and the telescopic end of the first hydraulic telescopic part 52... The first hydraulic telescopic part 52 is fixedly connected to the mounting base 22. The fixed end of the second hydraulic telescopic part 53 is fixedly connected to the side plate 12. The telescopic end of the second hydraulic telescopic part 53 is fixedly connected to the fixed end of the third hydraulic telescopic part 54. The telescopic end of the third hydraulic telescopic part 54 is fixedly connected to the clamping part 31. The fixed end of the fourth hydraulic telescopic part 55 is hinged to the mounting base. The telescopic end of the second hydraulic telescopic part 53 is hinged to the clamping rod 42. An oil pipe 56 is connected between the cylinders of the first hydraulic telescopic part 52 and the second hydraulic telescopic part 53. A metal hose 57 is connected between the third hydraulic telescopic part 54 and the fourth hydraulic telescopic part 55. A valve 58 is provided on the metal hose 57.

[0037] Before the power steel pipe pole is placed on the support device, under the action of the return spring 51 and the first torsion spring, the mounting base 22 is at the top of the column 11, and the clamping rod 42 is in a vertical state. At this time, the lengths of the first hydraulic telescopic part 52 and the third hydraulic telescopic part 54 are at their longest, and the lengths of the second hydraulic telescopic part 53 and the fourth hydraulic telescopic part 55 are at their shortest.

[0038] After the workers place the power steel pipe pole onto the support member 21 of the support device using a crane, under the weight of the power steel pipe pole, the support member 21 slides downward on the column 11 via the mounting base 22. At this time, the first hydraulic telescopic part 52 is compressed, and the hydraulic oil inside is introduced into the second hydraulic telescopic part 53 through the oil pipe 56. The second hydraulic telescopic part 53 extends, which drives the third hydraulic telescopic part 54 and the clamping part 31 to move together toward one side of the power steel pipe pole. As the support member 21 continues to move, the third hydraulic telescopic part 54 and the clamping part 31 continue to move toward one side of the power steel pipe pole. When the clamping part 31 contacts the power steel pipe pole, the continued downward movement of the support member 21 will compress the third hydraulic telescopic part 54. When the third hydraulic telescopic part 54 is compressed, the hydraulic oil inside will be introduced into the fourth hydraulic telescopic part 55 through the metal hose 57, causing the fourth hydraulic telescopic part 55 to extend. The extension of the fourth hydraulic telescopic part 55 will push the clamping rod 42 to rotate around its rotation axis 41 toward the power steel pipe pole. When the clamping rod 42 contacts the power steel pipe pole, the clamping rod 42 can no longer rotate in the direction of the power steel pipe pole, that is, the third hydraulic telescopic part 54 cannot be compressed, and the clamping part 31 cannot move further in the direction of the power steel pipe pole, that is, the second hydraulic telescopic rod cannot extend further, thereby fixing the mounting base 22 in this position. At this time, the operator only needs to close the valve 58 to complete the clamping work of the power steel pipe pole.

[0039] The present invention only requires placing the power steel pipe pole on the supporting member 21 of the support device, and the clamping part 31 and the clamping rod 42 can automatically complete the corresponding clamping work, thereby completing the clamping work of six clamping points for power steel pipe poles of different sizes. This not only reduces the labor intensity of workers, but also improves the loading efficiency of power steel pipe poles.

[0040] In addition, when it is necessary to remove the power steel pipe pole, simply open valve 58 and use a crane to lift the power steel pipe pole upwards, and the power steel pipe pole can be removed from the support device.

[0041] In a specific embodiment of the present invention, the supporting member 21 is V-shaped in general, including a central column 211, inclined columns 212 connected to both ends of the central column 211, and a connecting column 213 connected to one end of the inclined column 212 away from the central column 211. The clamping part 31 includes a clamping column 311 and movable columns 312 connected to both ends of the clamping column 311. A clamping plate 32 is rotatably provided on the inclined column 212, the clamping rod 42 and the clamping column 311, and the clamping plate 32 is provided with a rubber pad.

[0042] Based on the above design, when clamping the power steel pipe pole, the clamping plate 32 can deflect accordingly from the inclined column 212, the clamping rod 42, and the clamping column 311 to increase the contact area with the power steel pipe pole in the axial direction (the reason is that the outer circumference of the power steel pipe pole is conical, and if a flat clamp is used, the contact area with the power steel pipe pole is small). Furthermore, when the power steel pipe pole moves axially due to inertia after braking, the flipping plate can flip and further increase the clamping force on the power steel pipe pole, thereby preventing the power steel pipe pole from axially shifting on the support device.

[0043] In a specific embodiment of the present invention, the first hydraulic telescopic part 52 includes a first hydraulic cylinder 521, a first piston 522 slidably disposed in the first hydraulic cylinder 521, and a first movable rod 523 vertically disposed on the top of the first piston 522. The bottom end of the first hydraulic cylinder 521 is fixedly connected to the base plate 1, the top end of the first movable rod 523 is fixedly connected to the bottom of the mounting base 22, and the reset spring 51 is disposed between the first hydraulic cylinder 521 and the mounting base 22.

[0044] In a specific embodiment of the present invention, the second hydraulic telescopic part 53 includes a second hydraulic cylinder 531 vertically fixed on the side plate 12, a second piston 532 slidably disposed in the second hydraulic cylinder 531, and a second movable rod 533 vertically disposed on the side of the second piston 532 away from the side plate 12. One end of the oil pipe 56 is connected to the bottom end of the first hydraulic cylinder 521, and the other end of the oil pipe 56 is connected to the side of the second hydraulic cylinder 531 near the side plate 12.

[0045] In a specific embodiment of the present invention, the third hydraulic telescopic part 54 includes a fixing bar 541 fixed to one end of the second movable rod 533 away from the second piston 532. The bottom end of the fixing bar 541 is fixedly connected to the movable seat. A piston cavity 542 is provided inside the fixing bar 541. A third piston 543 is provided inside the piston cavity 542. The clamping part 31 is provided on the side of the fixing bar 541 away from the side plate 12. The connecting seat of the clamping part 31 extends and is fixedly connected to the third piston 543.

[0046] In a specific embodiment of the present invention, the fourth hydraulic telescopic part 55 includes a fourth hydraulic cylinder 551, a fourth piston 552 slidably disposed within the fourth hydraulic cylinder 551, and a fourth movable rod 553 vertically disposed on the top of the fourth piston 552. One end of the fourth hydraulic cylinder 551 away from the fourth movable rod 553 is hinged to the top of the mounting base 22. One end of the fourth movable rod 553 away from the fourth piston 552 is hinged to the clamping rod 42. One end of the oil pipe 56 is connected to the end of the fourth hydraulic cylinder 551 away from the fourth movable rod 553, and the other end of the oil pipe 56 is connected to the side of the piston chamber 542 away from the clamping part 31.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
