[0002] Tower assembly is an important part of power transmission line construction. In addition to using mobile cranes to assemble towers in places with convenient road traffic, there are also ways to use suspended poles and ground poles to assemble towers (both use pole-holding operations to assemble towers). However, pole-holding operations to assemble towers have high safety risks, heavy moving weight, many auxiliary devices, and low production efficiency. To solve these problems, a new type of four-column deformable self-lifting tower assembly equipment that can rise along the tower structure has appeared on the market. The key to whether the four-column deformable self-lifting tower assembly equipment can operate normally is that during the deformation of the four columns, the column always maintains the stress state of the two-force rods, and uses the deformation and movement of the legs to perform tower assembly operations.

DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0042] like Figures 1 to 12 As shown, the present application provides a four-column deformable self-lifting tower assembly equipment leg restraint device, including a support mechanism 1 and a rotating mechanism 2, the support mechanism 1 is suitable for fixed connection with a tower structure 3, and the tower structure 3 here refers to the original basic structure on the tower body including tower body angle steel, cross arm angle steel, tower body steel pipe, cross arm steel pipe, tower boot 31, etc.

[0043] The rotating mechanism 2 includes a rotating component 21 and a swinging core shaft 22. The rotating component 21 is suitable for being rotatably connected to the supporting mechanism 1. The swinging core shaft 22 is arranged on the rotating component 21. The leg 4 of the tower assembly equipment is suitable for being hinged with the swinging core shaft 22. The leg 4 of the tower assembly equipment is suitable for rotating around the swinging core shaft 22 in a first plane. The leg 4 of the tower assembly equipment is suitable for rotating around the rotating component 21 in a second plane. The leg 4 of the tower assembly equipment transfers the lifting weight and equipment weight to the tower structure 3 through the swinging core shaft 22. The rotating mechanism 2 can realize a universal connection between the supporting mechanism 1 and the leg 4 of the tower assembly equipment through relative rotation in the first plane and the second plane, so as to help the supporting mechanism 1 adapt to the deformation and movement of the leg 4 of the tower assembly equipment during the self-lifting process, reduce the probability of torsion between the supporting mechanism 1 and the leg 4 of the tower assembly equipment, and improve the operation stability.

[0044] like Figure 1 to Figure 2 In the illustrated embodiment, the rotating assembly 21 includes a guide core shaft 211 and a turntable 212, the turntable 212 is sleeved on the outside of the guide core shaft 211, the swing core shaft 22 radially passes through the guide core shaft 211 and the turntable 212, the supporting mechanism 1 includes at least two spaced apart supporting plates 13, both ends of the guide core shaft 211 are suitable for being rotatably connected to two adjacent supporting plates 13 respectively, the turntable 212 is embedded between the two adjacent supporting plates 13, and the leg 4 of the tower assembly equipment is suitable for rotating around the guide core shaft 211 in the second plane.

[0045] It can be understood that the rotation function of the rotating mechanism 2 in the first plane and the second plane can be achieved by relying solely on the guide core shaft 211 and the swing core shaft 22. By adding a turntable 212, the structural strength and connection strength of the rotating mechanism 2 can be improved, and a reliable connection between the support mechanism 1 and the leg 4 of the tower assembly equipment can be achieved, so that the bearing capacity meets the weight requirements of the lifting and tower assembly equipment.

[0046] like Figures 3 to 7 In the illustrated embodiment, the support mechanism 1 comprises a first clamping plate member 11 and a second clamping plate member 12, wherein the first clamping plate member 11 and the second clamping plate member 12 are suitable for being matched and connected and fastened on the tower structure 3. Normally, the tower structure 3 here refers to a tower structure 3 at a certain height from the ground. By installing the support mechanism 1, a movable attachment point can be formed on the tower structure 3 to assist in lifting the tower assembly equipment. During installation, the first clamping plate member 11 and the second clamping plate member 12 are first installed on the movable attachment point, and then the turntable 212 is wedged between the two support plates 13, so that the guide core shaft 211 passes through the support plate 13 and the turntable 212, and the two ends of the guide core shaft 211 are locked to prevent disengagement, the swing core shaft 22 is installed, and the leg 4 of the tower assembly equipment is connected to complete the connection. Similarly, the separation between the movable attachment point and the tower assembly equipment can be completed in the opposite manner.

[0047] In some embodiments, the distance between two adjacent support plates 13 at the movable attachment point is slightly greater than the height of the turntable 212 .

[0048] In some embodiments, when the main body of the tower structure 3 is composed of an angle steel structure, the first clamping plate member 11 and the second clamping plate member 12 are suitable for being matched and connected and fastened on the inner and outer sides of the angle steel structure. In the present application, the inner side of the angle steel structure refers to the side of the angle steel structure facing the main body of the tower structure 3, which can also be understood as the recessed side of the angle steel structure. A support plate 13 is provided on the first clamping plate member 11, and the two ends of the rotating assembly 21 are respectively connected to two adjacent support plates 13.

[0049] Among them, when only one support plate 13 is provided on the first clamping plate component 11, the two ends of the rotating component 21 can be respectively connected to the support plates 13 on two different first clamping plate components 11, and the distance between the two different first clamping plate components 11 can be freely adjusted, so as to adapt to rotating components 21 of different specifications and have higher installation flexibility.

[0050] Among them, when multiple support plates 13 are arranged on the first clamping plate component 11, the two ends of the rotating component 21 can be respectively connected to two adjacent support plates 13 on the same first clamping plate component 11. This arrangement enables the first clamping plate component 11 to have higher structural strength to stably support the connection between the rotating component 21 and the leg 4 of the tower assembly equipment.

[0051] In some embodiments, the cross-section of the first clamping plate member 11 and the second clamping plate member 12 is L-shaped, which can be connected to the angle steel structure. In the present application, the support plate 13 is usually arranged in the recess of the first clamping plate member 11, which can also effectively improve the setting strength of the support plate 13, improve the bearing capacity of the support plate 13, and reduce the probability of compression deformation.

[0052] In some embodiments, the first clamping plate member 11 and the second clamping plate member 12 are adapted to cooperate with each other to clamp the tower structure 3, and fasteners are connected on both sides of the outside of the tower structure 3 to achieve a fixed connection structure in the form of embracing and tightening the tower structure 3 there. The fasteners include general fasteners such as bolts and nuts. There is no need to modify or destroy the original tower structure 3, thereby improving installation efficiency and reducing the impact on the stability of the tower structure 3. Specifically: like Figures 3 to 5 In the illustrated embodiment, when the movable attachment point is arranged on the tower angle steel structure of the tower structure 3, both sides of the first clamping plate member 11 and both sides of the second clamping plate member 12 extend to the outside of the tower angle steel structure and are suitable for being connected by fasteners on the outside of the tower angle steel structure.

[0053] like Figures 6 to 7In the illustrated embodiment, when the movable attachment point is arranged on the cross-arm angle steel structure of the tower structure 3, the end of the first clamping plate member 11 extends to the outside of the cross-arm angle steel structure, and both sides of the second clamping plate member 12 extend to the outside of the cross-arm angle steel structure, and the second clamping plate member 12 is suitable for being connected to the end of the first clamping plate member 11 through fasteners.

[0054] In some embodiments, when the main body of the tower structure 3 is composed of a steel pipe structure, the first clamping plate member 11 and the second clamping plate member 12 are suitable for being connected and fastened on both sides of the steel pipe structure, and a support plate 13 is provided on the first clamping plate member 11, and the two ends of the rotating assembly 21 are respectively connected to two adjacent support plates 13.

[0055] At this time, the cross-sectional bodies of the first clamping plate member 11 and the second clamping plate member 12 are at least partially configured as arc segments, which can cooperate with each other to be clamped onto the steel pipe structure. Both sides of the first clamping plate member 11 and both sides of the second clamping plate member 12 extend to the outside of the steel pipe structure, and are suitable for being connected on both sides outside the steel pipe structure by fasteners to form a clamp structure (not shown in the figure of this embodiment).

[0056] like Figures 8 to 9 In the illustrated embodiment, the support mechanism 1 includes a support plate 13, which is suitable for being welded and fixed to the angle steel structure on the tower structure 3. The two ends of the rotating assembly 21 are respectively connected to the two support plates 13. By welding the support plates 13, a fixed attachment point can be formed on the tower structure 3 to assist in lifting the tower assembly equipment. A plurality of support plate 13 welding points can be designed for the entire height of the tower body. During installation, the turntable 212 is first wedged between the two support plates 13, and then the guide core shaft 211 is passed through the support plate 13 and the turntable 212. The two ends of the guide core shaft 211 are locked to prevent disengagement, the swing core shaft 22 is installed, and the leg 4 of the tower assembly equipment is connected to complete the connection. Similarly, the separation between the fixed attachment point and the tower assembly equipment can be completed in the opposite manner.

[0057] In some embodiments, the distance between two adjacent support plates 13 at the fixed attachment point is slightly greater than the height of the turntable 212 .

[0058] like Figures 10 to 12 In the illustrated embodiment, the support mechanism 1 includes an auxiliary bracket 14 and a connecting plate 15. The connecting plate 15 is suitable for connecting the base plate of the auxiliary bracket 14 and the tower shoe 31 in the tower structure 3. The connecting plate 15 is suitable for being fastened to the base plate of the auxiliary bracket 14 and the top of the tower shoe 31. At least one section of angle steel structure is provided on the auxiliary bracket 14 to connect the rotating mechanism 2.

[0059] Since there is no tower material for attaching and installing the legs 4 of the tower assembly equipment during the initial installation of the iron tower, the design uses an auxiliary bracket 14 for alternative operation. The auxiliary bracket 14 is connected and fixed by the foundation bolts on the tower shoe 31, has high stability, and is convenient to install, position and separate.

[0060] in: like Fig.10 In the illustrated embodiment, the auxiliary bracket 14 includes a first support member 141, a second support member 142 and a base plate 143. The first support member 141 stands on the base plate 143. At least one section of angle steel structure is arranged on the first support member 141. The angle steel structure can adapt to the setting of fixed attachment points or movable attachment points, thereby increasing the commonality of parts and improving the installation applicability and efficiency.

[0061] In some embodiments, the angle steel structure of the first support member 141 is suitable for welding the support plate 13 to achieve the setting of a fixed attachment point.

[0062] In some embodiments, the angle steel structure of the first supporting member 141 is also suitable for mounting the first clamping plate member 11 and the second clamping plate member 12 to achieve the setting of movable attachment points.

[0063] like Fig.10 In the illustrated embodiment, the second support member 142 is disposed on the first support member 141. The second support member 142 is located above the angle steel structure of the first support member 141 and extends toward the inner side of the angle steel structure of the first support member 141. The second support member 142 can assist in the lifting of the rotating mechanism 2, increase the installation form of the rotating mechanism 2, and enhance the installation flexibility.

[0064] In some embodiments, the first support member 141 and the second support member 142 are made entirely of angle steel, which is easy to install and has low cost, and there is no need to set up a separate angle steel structure.

[0065] like Fig.11 In the illustrated embodiment, a connection port 151 is provided on the connection plate 15, and the connection port 151 is suitable for wedging into the original anchor bolts on the tower shoe 31, so that the connection plate 15 is connected to the tower shoe 31, which is convenient for positioning with the tower structure 3, and can also make full use of the original structure of the tower base and the tower shoe 31, thereby improving the structural stability and bearing capacity, and improving the installation efficiency.

[0066] In some embodiments, a plurality of connection ports 151 are provided on the connection plate 15, which are respectively used for the original anchor bolts on the tower shoe 31 and the welding bolts on the bottom plate of the auxiliary bracket 14, and then tightened by nuts.

[0067] Since the connecting plate 15 is fixed by pressing the auxiliary bracket 14 and the tower shoe 31, the area of ​​the connecting plate 15 determines the connection stability between the auxiliary bracket 14 and the tower shoe 31 to a certain extent. In actual use, the area of ​​the connecting plate 15 can be appropriately increased to improve the connection stability.
