Description

Technical Field

[0001] This utility model relates to the field of iron tower component transportation technology, specifically to an iron tower component transportation fixing frame. Background Technology

[0002] In the construction of infrastructure such as power, communications, and transportation, the application scope of iron towers as key support structures is continuously expanding with the upgrading of power grids, the expansion of 5G network coverage, and the advancement of smart transportation construction. The construction of iron towers relies on the on-site assembly of a large number of prefabricated components. These components need to be transported from the production base to the construction site by road, rail or waterway. Among the transportation links, the transportation of the main structural components of the iron tower accounts for the highest proportion and is the most difficult to operate, which has become the core pain point restricting the efficiency and cost control of iron tower construction.

[0003] Existing methods for transporting and securing tower components mostly rely on welding temporary supports and manually binding them with wire ropes or chains. These methods have significant drawbacks: First, the entire fixing process is manual, time-consuming, labor-intensive, and inefficient; furthermore, the tightness of the binding is difficult to maintain, posing safety hazards. Second, neither rigid supports nor flexible binding methods can adapt to irregularly shaped components with different cross-sectional shapes (such as circles or polygons) or surfaces with protrusions or holes, making them prone to loosening, collisions, or surface coating wear during transport due to shaking. Third, a single fixing device often only works for components of a specific specification, lacking versatility and adaptability. Various tooling configurations are required for diverse component types, increasing procurement and management costs. Therefore, we urgently need an automatic, reliable fixing solution that can adapt to multiple components to improve transportation efficiency and safety. Utility Model Content

The top surface of the driven rod is connected to the bottom surface of the lower slider. A motor base plate is connected to the left side of the U-shaped frame on the left side. The left side of the motor base plate is connected to the surface of the servo motor. The output shaft of the servo motor is splinedly connected to the bidirectional threaded drive rod. A threaded hole A is opened on the surface of the extrusion plate. The surface of the bidirectional threaded drive rod is connected to the threaded hole A. The surface of the extrusion plate is in contact with the surface of the driven rod.

[0009] As a further embodiment of this utility model: the surface of the bidirectional threaded drive rod is provided with a left-hand thread and a right-hand thread, and the threaded hole A on the extrusion plate includes a left-hand threaded hole and a right-hand threaded hole, and the left-hand thread and the right-hand thread are adapted to the corresponding threaded hole A on the extrusion plate.

[0010] As a further embodiment of this utility model: the right side of the U-shaped frame is connected to a limiting fixing plate, the surface of the limiting fixing plate is provided with a rotating hole A, the inner wall of the rotating hole A is connected to a bearing, and the inner wall of the bearing is connected to the outer surface of the right end of the bidirectional threaded drive rod.

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model, by setting up a dynamic clamping component and an overall fixing component, allows for the transportation of the main frame in the tower components. First, the main frame is placed horizontally between a set of eight clamping plates parallel to the U-shaped frame. After multiple main frames are placed between multiple sets of clamping plates, the servo motor is started. The servo motor drives the bidirectional threaded drive rod to rotate. Two pressing plates in one set move closer to each other. The two pressing plates move closer to each other, causing a set of eight sliding blocks to move. The four sliding blocks on the left move to the right along the slide rail bridge, and the four sliding blocks on the right move to the left along the slide rail bridge, until multiple clamping plates abut against the surface of the main frame. Since each clamping plate is connected to a spring, when the spring is compressed, it also experiences an interaction force that compresses the surface of the main frame. Multiple clamping plates on the same plane can clamp a fixing frame. Even if the main frame is equipped with side plates and mounting hole protrusions that need to be installed, the main frame with an irregular surface can be clamped by the dynamic clamping position of different clamping plates. This effectively improves the adaptability of the main frame in the tower components and can adapt to fixing main frames of different specifications, effectively improving the applicability of the device.

[0015] 2. This utility model features a lower sliding block and an upper connecting block, which are fixedly connected by bolts. When other tower components, such as angle steel, channel steel, and I-beams, need to be fixed, the upper connecting block can be quickly replaced. By replacing the upper connecting block, support vertical plates and rotating heads of different specifications can be replaced. By replacing support vertical plates of different lengths and coordinating the spacing of multiple slide rails, it is also possible to transport non-long, strip-shaped tower components of different specifications. The device components are easy to replace, and more tower components that need to be fixed can be adapted by quickly replacing parts, effectively improving the practicality and adaptability of the device.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see the appendix Figure 1 -Appendix Figure 7 This utility model discloses a transportation and fixing frame for iron tower components, including a transportation and fixing frame body 1. The transportation and fixing frame body 1 includes a base plate 2, a U-shaped frame 3, an overall fixing assembly 4, and a dynamic clamping assembly 5. The dynamic clamping assembly 5 includes a slide rail cross bridge 51, a lower slide block 52, an upper connecting block 53, a supporting vertical plate 54, a sliding rod 55, and a clamping plate 56. The bottom surfaces of both ends of the slide rail cross bridge 51 are connected to the top surface of the U-shaped frame 3. A sliding groove 511 is formed on the surface of the slide rail cross bridge 51. The inner wall of the sliding groove 511 is connected to the surface of the lower slide block 52. The top surfaces of the lower slide block 52 are connected to the bottom surfaces of the upper connecting block 53. The top surface of the upper connecting block 53 is connected to the bottom surface of the supporting vertical plate 54. A sliding hole A is formed on the surface of the supporting vertical plate 54. The inner wall of the sliding hole A is connected to the surface of the sliding rod 55. A rotating head 541 is provided at the end of the sliding rod 55 away from the supporting vertical plate 54. The surface of the rotating head 541 is connected to the surface of the clamping plate 56.

[0028] In the first embodiment, the lower slider 52 and the upper connecting block 53 are provided with insertion holes at both ends of their contact surfaces. The lower slider 52 and the upper connecting block 53 are connected by bolts through the insertion holes. A limiting block 542 is provided on the outer surface of the sliding rod 55 near the supporting vertical plate 54. The surface of the limiting block 542 is in contact with the surface of the supporting vertical plate 54. A spring 57 is provided on the end of the limiting block 542 near the clamping plate 56. The two ends of the spring 57 are respectively connected to the surface of the supporting vertical plate 54 and the rotating head 541.

[0029] Specifically, in the actual production and manufacturing process, the U-shaped frame 3 and the slide rail bridge 51 are connected by bolts. When it is necessary to fix the main frame with a greater degree of surface irregularity, the distance between two adjacent slide rail bridges 51 can be adjusted appropriately, and different shapes of driven rods 41 can be adapted to suit the application scenario. Even if the driven rods 41 have different shapes, their surfaces still abut against the surface of the extrusion plate 44. This ensures that the specific dimensions between two adjacent clamping plates 56 in each row are not the same, thus adapting to main frames with more parameter specifications.

[0030] In embodiment two, the overall fixing assembly 4 includes a driven rod 41, a bidirectional threaded drive rod 42, a servo motor 43, and a pressing plate 44. The top surface of the driven rod 41 is connected to the bottom surface of the lower slider 52. A motor base plate 431 is connected to the left side of the left U-shaped frame 3. The left side of the motor base plate 431 is connected to the surface of the servo motor 43. The output shaft of the servo motor 43 is splinedly connected to the bidirectional threaded drive rod 42. A threaded hole A441 is opened on the surface of the pressing plate 44. The surface of the bidirectional threaded drive rod 42 is connected to the threaded hole A441. The surface of the pressing plate 44 is in contact with the surface of the driven rod 41. A left-hand thread 421 and a right-hand thread 422 are opened on the surface of the bidirectional threaded drive rod 42. The threaded hole A441 on the extrusion plate 44 includes a left-hand threaded hole and a right-hand threaded hole. The left-hand thread 421 and the right-hand thread 422 are adapted to the corresponding threaded hole A441 on the extrusion plate 44. The right side of the right U-shaped frame 3 is connected to a limiting fixing plate 45. The surface of the limiting fixing plate 45 is provided with a rotating hole A. The inner wall of the rotating hole A is connected to a bearing. The inner wall of the bearing is connected to the outer surface of the right end of the bidirectional threaded drive rod 42. A sliding round rod 46 is connected between the two sides of the two U-shaped frames 3 that are close to each other. The outer surfaces of both ends of the extrusion plate 44 are provided with sliding holes B. The inner wall of the sliding holes B is connected to the surface of the sliding round rod 46. The bottom surfaces of the two U-shaped frames 3 are connected to the two ends of the top surface of the base plate 2.

[0031] Specifically, in actual use, when it is necessary to fix arc-shaped tower components, the clamping plate 56 can be replaced with an arc shape. Since the contact between a plane and an arc-shaped surface is a line, while the contact between two planes is a surface, there are multiple stress points. When the clamping plate 56 is arc-shaped, the number of stress points can be increased, making the fixing of arc-shaped tower components more stable. Furthermore, when fixing tower components, anti-slip cotton can be set on the contact surface between the clamping plate 56 and the tower component, which can also improve the stability of fixing the tower components.

[0032] Working principle:

[0033] Clamping and fixing: When it is necessary to transport tower components (such as the main frame), place them horizontally between a set (usually eight) of parallel clamping plates 56, start the servo motor 43, drive the bidirectional threaded drive rod 42 to rotate. Since the left-hand thread 421 and right-hand thread 422 at both ends of the rod engage with the corresponding threaded holes on the two extrusion plates 44 respectively, the two extrusion plates 44 move synchronously towards each other under the guidance of the sliding round rod 46.

[0034] Power transmission and adaptive clamping: When the extrusion plate 44 moves, its surface pushes multiple driven rods 41 that are in contact with it. The driven rods 41 can be replaced with different contact surface shapes according to the contour characteristics of the component to be fixed, but their contact surface with the extrusion plate 44 always maintains planar contact to ensure stable power transmission. The driven rods 41 transmit the motion to the sliding rod 55 through the lower slider 52, the upper connecting block 53 and the support vertical plate 54, and finally drive all clamping plates 56 to move synchronously towards the center of the component.

[0035] Elastic self-adaptation: When the clamping plate 56 contacts the surface of the component, the spring 57 is compressed under the continuous drive of the servo motor 43, providing a continuous and adaptive elastic clamping force for the clamping plate 56. This design allows each clamping plate 56 to independently adjust its extension and retraction under the action of the spring 57, closely fitting the surface of the component and achieving reliable multi-point dynamic clamping.

[0036] Transportation and unloading: After the clamping is secure, transportation can be carried out. Upon arrival at the destination, the servo motor 43 is controlled to rotate in the opposite direction, driving the bidirectional threaded drive rod 42 to move the two extrusion plates 44 in opposite directions, thereby releasing the thrust on all driven rods 41. Under the reset action of the spring 57, each clamping plate 56 releases the components, and unloading is completed.
