Description

Technical Field

[0001] This invention relates to the technical field of steel pipe towers, and more particularly to a steel pipe tower node assembly platform device. Background Technology

[0002] Steel pipe towers are lattice-type towers mainly composed of steel pipes and structural steel. They serve as support structures for overhead transmission lines, supporting conductors and lightning protection wires. They ensure that conductors meet distance requirements to the ground and ground features, and can withstand the loads of the conductors, lightning protection wires, and their own components, as well as external loads. They possess significant advantages such as high cross-sectional stiffness, good cross-sectional stress characteristics, simple stress distribution, and aesthetically pleasing appearance, leading to their widespread adoption in lines of varying voltage levels. They are particularly prevalent in long-span structures and urban power grid tower structures.

[0003] K-type or star-shaped connection nodes are the main node types in power transmission steel pipe towers, and their safety is an important guarantee for the safety of the entire tower structure. K-type or star-shaped nodes mostly use connecting plates to connect the main pipe and branch pipes. Before connection, the connecting plate is welded to the side wall of the main pipe, and the end of the branch pipe is welded with a slotted plate. The slotted plate is fixed to the connecting plate with bolts, thus completing the splicing between the main pipe and the branch pipe.

[0004] Regarding the aforementioned prior art, the inventors believe that the assembly and welding of the connecting plate and the main pipe is often carried out by manual marking and positioning, which is not only inconvenient to operate, but also prone to skewing of the connecting plate due to the influence of welding stress, affecting the subsequent assembly accuracy.

[0029] This invention discloses a steel pipe tower node assembly platform device.

[0030] Reference Figure 1 and Figure 2 A steel pipe tower node assembly platform device includes a track platform 2 and a main pipe support device 3, a connecting plate splicing auxiliary device 4, a branch pipe rotation fixing device 5, a branch pipe support device 6, and a flange splicing device 7 installed on the track platform 2.

The worm gear and worm wheel are engaged in transmission, and the worm wheel is coaxially fixed with one end of the chuck 72. When welding and assembling the main pipe 1 and the flange, one end of the main pipe 1 is brought into contact with the flange. The height of the main pipe 1 is adjusted by the first lifting cylinder 32 so that the main pipe 1 and the flange are coaxial, and then welding is performed between the flange and the main pipe 1.

[0034] Reference Figure 3 and Figure 4 The connecting plate splicing auxiliary device 4 is installed on the main pipe 1. The connecting plate splicing auxiliary device 4 includes a first arc plate 41, a second arc plate 42 and a positioning and clamping assembly 46. A hinge 43 is provided at one end of the arc length direction of the first arc plate 41 and the second arc plate 42. The first arc plate 41 and the second arc plate 42 are hinged by the hinge 43. The inner wall curvature of the first arc plate 41 and the second arc plate 42 is the same as the outer wall curvature of the main pipe 1, so that when the first arc plate 41 and the second arc plate 42 are sleeved on the outside of the main pipe 1, they can keep in close contact with the outer wall of the main pipe 1.

[0035] Reference Figure 3 and Figure 4 The first arc plate 41 and the second arc plate 42 have the same arc length; a first mounting plate 44 is provided on the side of the first arc plate 41 away from the hinge 43, and a second mounting plate 45 is provided on the side of the second arc plate 42 away from the hinge 43.

The two first bidirectional lead screws 461 are located at both ends of the length direction of the first mounting plate 44. Each first bidirectional lead screw 461 passes through the first clamping plate 462 and the second clamping plate 463. The first clamping plate 462 and the second clamping plate 463 are threadedly connected to the first bidirectional lead screw 461, and the threads of the two plates are opposite in direction. One end of each first bidirectional lead screw 461 passes through the first mounting plate 44 and is fixed with a synchronous sprocket 464. The two synchronous sprockets 464 are connected by a chain 465. One end of one of the first bidirectional lead screws 461 passes through the corresponding synchronous sprocket 464 and is connected with a knob.

[0038] Reference Figure 3 and Figure 4 When assembling the connecting plate 12 and the main pipe 1, the connecting plate 12 is placed in the spacer groove between the first clamping plate 462 and the second clamping plate 463, and one side of the connecting plate 12 abuts against the outer wall of the main pipe 1. By rotating the knob, the first bidirectional lead screw 461 is driven to rotate, so that the first clamping plate 462 and the second clamping plate 463 move synchronously towards each other, thereby clamping and fixing the connecting plate 12 between the first clamping plate 462 and the second clamping plate 463, ensuring that the axis of the main pipe 1 is located in the plane of the connecting plate 12, and the connecting plate 12 is not prone to tilting. Then, the connecting plate 12 and the main pipe 1 are welded. Under the fixing action of the positioning clamping assembly 46, the connecting plate 12 will not be twisted or deflected under the action of welding stress, improving the connection convenience and installation accuracy of the connecting plate 12 and the main pipe 1. In order to facilitate welding operations between the connecting plate 12 and the main pipe 1, welding elongated holes 466 are provided on the side of the first mounting plate 44 near the first arc plate 41 and the side of the second mounting plate 45 near the second arc plate 42, so as to facilitate the insertion of the welding gun.

[0039] Reference Figure 2 and Figure 5 The branch pipe rotation and fixing device 5 includes a second base 51, a second lifting cylinder 52, a rotating platform 53, and a fixing mechanism 54. The second lifting cylinder 52 is bolted to the second base 51. The rotating platform 53 is fixedly connected to the telescopic rod of the second lifting cylinder 52. The fixing mechanism 54 is rotatably connected to the rotating platform 53. The fixing mechanism 54 clamps and fixes the branch pipe 11, and the rotatable connection between the fixing mechanism 54 and the rotating platform 53 facilitates the adjustment of the angle of the branch pipe 11, improving the installation convenience between the branch pipe 11 and the main pipe 1.

[0040] Reference Figure 2 and Figure 5The fixing mechanism 54 includes a base plate 541, clamping blocks 544, and a second bidirectional lead screw 543. The base plate 541 is rotatably connected to the rotary table 53. An adjustment groove 542 is provided on the base plate 541. The second bidirectional lead screw 543 is rotatably inserted into the adjustment groove 542. Two clamping blocks 544 are provided. The bottom of the clamping blocks 544 is slidably connected to the adjustment groove 542. The second bidirectional lead screw 543 passes through the bottom of the clamping blocks 544 and is threadedly connected to the clamping blocks 544. The threaded connections between the two clamping blocks 544 and the second bidirectional lead screw 543 are in opposite directions. A "V"-shaped clamping groove is provided on the side of the clamping blocks 544 that is close to each other, which facilitates clamping of branch pipes 11 of different diameters. A second guide groove 22 is provided on the track platform 2. A second slider 55 adapted to the second guide groove 22 is welded to the bottom surface of the second base 51. The second slider 55 is slidably connected in the second guide groove 22. The structure of the branch pipe support device 6 is the same as that of the main pipe support device 3, so it will not be described in detail. Four rollers are installed at the bottom of the branch pipe support device 6 to facilitate the movement of the branch pipe support device 6 and thus facilitate the adjustment of the angle of the branch pipe 11.

[0041] The working principle of a steel pipe tower node assembly platform device according to an embodiment of the present invention is as follows: First, the main pipe 1 is hoisted onto the main pipe support device 3, and the flange is clamped on the chuck 72; when welding and assembling the main pipe 1 and the flange, one end of the main pipe 1 is brought into contact with the flange, and the height of the main pipe 1 is adjusted by the first lifting cylinder 32 so that the main pipe 1 and the flange are coaxial, and then the welding between the flange and the main pipe 1 is carried out. The connecting plate splicing auxiliary device 4 is installed on the main pipe 1. When assembling the connecting plate 12 with the main pipe 1, the connecting plate 12 is placed in the gap between the first clamping plate 462 and the second clamping plate 463, and one side of the connecting plate 12 abuts against the outer wall of the main pipe 1. By rotating the knob, the first bidirectional lead screw 461 is driven to rotate, so that the first clamping plate 462 and the second clamping plate 463 move synchronously towards each other, thereby clamping and fixing the connecting plate 12 between the first clamping plate 462 and the second clamping plate 463, ensuring that the axis of the main pipe 1 is located in the plane of the connecting plate 12, and the connecting plate 12 is not prone to tilting. Then the connecting plate 12 and the main pipe 1 are welded. Under the fixing action of the positioning clamping component 46, the connecting plate 12 will not be twisted or deflected under the action of welding stress, improving the connection convenience and installation accuracy of the connecting plate 12 and the main pipe 1. Then, the branch pipe 11 is hoisted onto the branch pipe support device 6 and the branch pipe rotation fixing device 5. The branch pipe 11 is clamped and fixed by rotating the second screw. Then, the angle of the branch pipe 11 is adjusted, and the branch pipe 11 is connected and fixed to the main pipe 1 by using the slotted insert plate 13.
