Description

Technical Field

[0001] The invention relates to the technical field of horizontal and oblique rod flange assembly, in particular to an iron tower horizontal and oblique rod flange assembly tool. Background Art

[0002] There are several horizontal and oblique rods on iron towers such as transmission towers or TV towers. The horizontal and oblique rods are composed of steel pipes and flanges on both sides. Unlike the main columns of the tower, the diameter and length of the horizontal and oblique rods are smaller. During installation and production, after the Farah plates on both sides are relatively fixed, the steel pipe and the flange are inserted and docked or pressed together, and the fixed connection between the steel pipe and the flange is achieved by riveting or welding. The holes of the flanges on both sides need to be concentrically relative to each other. The existing installation method uses two relatively movable clamps to clamp and fix the flanges on both sides respectively. The clamps can adapt to flanges of different diameters. The holes on the circumference of the two flanges are made concentrically relative to each other through indicating marks, and then the steel pipe is lifted by a crane and docked or plugged with the flange. The two clamps are relatively close to clamp the steel pipe and the flange, and finally welding or riveting are performed to complete the fixed connection.

[0003] In the existing tooling, the chucks on both sides that are far away from each other may have relative deviations, making it difficult to keep the holes of the two flanges concentrically relative to each other. The problem of hole deviation is prone to occur and needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tower horizontal and oblique rod flange assembly tooling to address the above-mentioned technical deficiencies, which solves the problem that the existing tooling is difficult to keep the holes of the two flanges concentrically relative to each other and is prone to hole deviation.

[0005] The technical solution adopted by the present invention is to provide a tower horizontal and oblique rod flange assembly tool for connecting the steel pipe of the horizontal and oblique rod with the flanges on both sides, including:

[0006] a first positioning assembly for fixing a flange, the first positioning assembly comprising a base, a first fetal position, a back plate, and a support member, the first fetal position being slidably disposed on the base, the first fetal position being used to fix a flange, the back plate being slidably disposed on the base, the support member being located between the back plate and the first fetal position, one end of the support member acting on the first fetal position and the other end acting on the back plate, for providing a force for moving the back plate and the first fetal position away from each other;

[0007] a second positioning assembly, the second positioning assembly comprising a second position, the second position being arranged opposite to the first position, the second position being used to fix another flange, the steel pipe being located between the two flanges;

[0008] There are at least three pull ropes, one end of which acts on the second fetal position, and the other end passes through the first fetal position and is connected to the backboard.

[0009] To further optimize the technical solution, the second positioning component has the same structure as the first positioning component, the second positioning component is arranged opposite to the first positioning component, and both sides of the pull rope are respectively connected to the backboards on both sides.

[0010] Further optimizing the technical solution, the middle portion of the first fetal position is provided with a chute, further comprising:

[0011] There are two sliders, which are arranged to slide relative to each other and slide in the sliding groove. The sliders are provided with through holes, and the flange is connected to the sliders by bolts passing through the through holes.

[0012] To further optimize this technical solution, the first positioning component further includes:

[0013] A forward and reverse screw is rotatably arranged on the first fetal position, and the two sliders are both threadedly connected to the forward and reverse screw, and the forward and reverse screw is used to drive the two sliders to slide relative to each other;

[0014] There are two positioning blocks, each of the sliders is followed by a positioning block, and the positioning blocks are threadedly connected to the forward and reverse lead screws;

[0015] There are two compression springs, one of which is provided on each positioning block. One end of the compression spring acts on the positioning block, and the other end acts on the slider, so as to provide a force to move the positioning block and the slider away from each other.

[0016] Further optimizing this technical solution, the support member includes:

[0017] A mounting plate, one end of which has a plurality of sleeves, the sleeves corresponding to the positions of the pull ropes one by one, the sleeves being slidably sleeved on the pull ropes, and the ends of the sleeves being used to abut against the first fetal position;

[0018] A threaded rod is threadedly connected to the back plate, and an end of the threaded rod abuts against the mounting plate.

[0019] To further optimize the technical solution, a positioning hole is provided on the first fetal position, the pull rope passes through the positioning hole, and the diameter of the positioning hole is larger than the diameter of the pull rope; the end of the sleeve has a positioning part, and the positioning part is inserted into the positioning hole.

[0020] To further optimize the technical solution, there are three pull ropes and three positioning holes, one of which is located in the lower middle part of the first fetal position, and two of the positioning holes are respectively located on both sides of the upper part of the first fetal position.

[0021] Further optimizing the technical solution, the lower portion of the first fetal position has a vertically arranged adjustment groove; further comprising:

[0022] The bottom block is slidably arranged on the adjusting groove, and the upper end of the bottom block is used to abut against the lower side of the flange.

[0023] The beneficial effects of the present invention are:

[0024] 1. The first positioning assembly and the second positioning assembly align and fix the flange through the fetal position. The first fetal position and the back plate in the first positioning assembly are moved away from each other through the support member, so that the pull rope is tightened and straightened, and then the first fetal position and the second fetal position clamp the flange and the steel pipe, which can improve the relative concentricity of the first fetal position and the second fetal position, and improve the concentricity of the holes of the flanges on both sides.

[0025] 2. Compared to the existing track guide system that restricts the two fetal positions (or chucks in the existing technology) to be aligned, the track deforms and the initial direction of the track guide is offset, which ultimately prevents the two flanges from being aligned and causes the hole positions to deviate. The pull rope of the present invention can be made of steel wire rope, which has high straightness after being stretched and straightened, and simultaneously enables the first and second fetal positions to be aligned. The first fetal position is arranged parallel to the back plate, and when supported by the support member, the back plate and the first fetal position move parallel to each other and away from each other.

In this text, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0036] In this text, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0037] In addition, in the description of this application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] As Figure 1-7As shown, a flange assembly tool for a horizontal and oblique rod of an iron tower is used for docking a steel pipe 1 of a horizontal and oblique rod with flanges 2 on both sides, including: a first positioning component 3 for fixing a flange 2, the first positioning component 3 including a base 4, a first position 5, a back plate 6 and a support 7, the first position 5 being slidably arranged on the base 4, the first position 5 being used to fix a flange 2, the back plate 6 being slidably arranged on the base 4, the support 7 being located between the back plate 6 and the first position 5, one end of the support 7 acting on the first position 5, and the other end acting on the back plate 6, for providing a force for the back plate 6 and the first position 5 to move away from each other; a second positioning component 8, the second positioning component 8 including a second position 801, the second position 801 being arranged opposite to the first position 5, the second position 801 being used to fix another flange 2, and the steel pipe 1 being located between the two flanges 2; a pull rope 9, having at least three, one end of the pull rope 9 acting on the second position 801, and the other end passing through the first position 5 and connected to the back plate 6.

[0039] When in use, the first positioning assembly 3 and the second positioning assembly 8 are arranged oppositely and at intervals, fixing one flange 2 on the first fetal position 5 and the other flange 2 on the second fetal position 801. The holes on the rings of the flanges 2 on both sides can be fixed at the same angle and the holes are concentrically opposite to each other according to the markings. The steel pipe 1 is lifted so that one side of the steel pipe 1 is connected to a flange 2. Then the support member 7 acts on the back plate 6 and the first fetal position 5, so that the back plate 6 and the first fetal position 5 are parallel and away from each other, and the back plate 6 is also away from the second fetal position 801, so that the pull rope 9 is tightened and straightened, and the first fetal position 5 is close to the second fetal position 801, clamping the steel pipe 1 and the flange 2. The two sides of the steel pipe 1 are respectively connected to the flanges 2 on both sides. After the connection is completed, preliminary welding and other connection processes can be carried out.

[0040] In the first positioning assembly 3, the sliding fit between the back plate 6 and the first positioning assembly 3 and the base 4 is a clearance fit, which can produce a small amount of shaking to achieve the first fetal position 5 and the second fetal position 801 on both sides facing each other after the pull rope 9 is tightened and straightened. There is no need to consider factors such as deformation of the sliding connection structure or guidance error. Relying on the tensioning and straightening of the pull rope 9 to achieve guidance is conducive to ensuring the opposite state of the fetal positions on both sides. The back plate 6 and the first fetal position 5 do not need to remain parallel throughout the process of moving away from each other. Finally, the pull rope 9 is tightened and straightened to naturally parallelize. One end of the pull rope 9 acts on the second fetal position 801 in the second positioning assembly 8, and the end of the pull rope 9 can be fixedly connected to the second fetal position 801. At least three pull ropes 9 are provided, which can provide guidance after being tightened and straightened from three points spaced apart from each other and located on the periphery of the flange 2. When the number is small, the effect of keeping the first fetal position 5 and the second fetal position 801 parallel and facing each other is poor.

[0041] In the second positioning assembly 8, the second fetal position 801 can be fixed on the ground and used as a reference. The second positioning assembly 8 can also be identical in structure to the first positioning assembly 3 and positioned opposite each other, i.e., the second fetal position 801 and the first fetal position 5 are also identical in structure. During initial placement, the first positioning assembly 3 and the second positioning assembly 8 are adjusted to the same height and opposite each other.

[0042] The support member 7 can be a telescopic structural component, which allows the backboard 6 and the first fetal position 5 to move away and eventually become parallel. The support member 7 can also be a wedge-shaped structural member with symmetrical inclined surfaces on both sides for propping up the backboard 6 and the first fetal position 5.

[0043] Furthermore, the second positioning assembly 8 has the same structure as the first positioning assembly 3 , and the second positioning assembly 8 is arranged opposite to the first positioning assembly 3 , and both sides of the pull rope 9 are respectively connected to the backboard 6 on both sides.

[0044] During use, the positioning assembly is divided into a first positioning assembly 3 and a second positioning assembly 8, both of which have the same structure. Both positioning assemblies can achieve parallel and distance between the fetal position and the backboard 6, increasing the adjustment range to accommodate steel tubes 1 of different lengths. The end of the pull rope 9 acts on the second fetal position 801 through the backboard 6 and support member 7 in the second assembly.

[0045] The pull rope 9 is fixed on the back plate 6. One end of the pull rope can be fixed on the back plate 6 in the second positioning component 8, and the other end passes through the second fetal position 801 and the first fetal position 5 in turn, and is fixedly connected to the back plate 6 in the first positioning component 3 with an adjustable length, so as to adapt to steel pipes 1 of different lengths in a wider range.

[0046] Furthermore, the first fetal position 5 has a slide groove 501 in the middle, and also includes: two sliders 502, the two sliders 502 are set to slide relative to each other, and are slidably set in the slide groove 501, and the slider 502 has a through hole 5021, and the flange 2 is connected to the slider 502 by bolts passing through the through hole 5021. The first positioning assembly 3 also includes: a forward and reverse screw 503, which is rotatably set on the first fetal position 5, and the two sliders 502 are both threadedly connected to the forward and reverse screw 503, and the forward and reverse screw 503 is used to drive the two sliders 502 to slide relative to each other; there are two positioning blocks 504, each of the sliders 502 is followed by a positioning block 504, and the positioning block 504 is threadedly connected to the forward and reverse screw 503; there are two compression springs 505, each of the positioning blocks 504 is provided with a compression spring 505, one end of the compression spring 505 acts on the positioning block 504, and the other end acts on the slider 502, for providing a force for the positioning block 504 and the slider 502 to move away from each other.

[0047] During use, the two sliders 502 in the positioning assembly are bolted to two holes on the diameter of the flange 2, respectively. After the flanges 2 are fixed on both sides, they are concentrically aligned along the annular holes. The two sliders 502 are driven by the forward and reverse screws 503 to move synchronously relative to each other, accommodating flanges 2 of varying diameters. Ultimately, the flange 2 is centered, facilitating alignment of the flanges 2 on both sides.

[0048] The positioning block 504 and the compression spring 505 act on the slider 502, eliminating the gap between the slider 502 and the forward and reverse screw 503, ensuring the centering effect of the two sliders 502 after being connected to the flange 2, reducing deviation, and allowing the flanges 2 on both sides to face each other. The positioning block 504 is threadedly connected to the forward and reverse screw 503. When the forward and reverse screw 503 rotates, the corresponding positioning block 504 and slider 502 move synchronously, with the gap between them being roughly unchanged. The force exerted by the compression spring 505 on the slider 502 will not be excessively reduced or increased. The compression spring 505 can be mounted on the periphery of the forward and reverse screw 503, and one end of the positioning block 504 can slide against one side of the back plate 6.

[0049] Furthermore, the support member 7 includes a mounting plate 701 having a plurality of sleeves 7011 at one end, each sleeve corresponding to the position of the pull cord 9. The sleeves 7011 are slidably mounted on the pull cord 9, with the ends of the sleeves 7011 being designed to abut the first fetal position 5; a threaded rod 702 threadedly connected to the back plate 6, with the ends of the threaded rod 702 abutting the mounting plate 701. The first fetal position 5 has a positioning hole 506 through which the pull cord 9 passes, and the positioning hole 506 has a larger diameter than the pull cord 9; and a positioning portion 7012 at the end of the sleeve 7011, which is inserted into the positioning hole 506. The pull cord 9 has three positioning holes 506, one of which is located in the lower middle portion of the first fetal position 5, and two of which are located on either side of the upper portion of the first fetal position 5.

[0050] During use, the support member 7 can prop open the back panel 6 and the first fetal position 5 via a threaded connection. The threaded rod 702 is threadedly connected to the middle portion of the back panel 6. Rotating the threaded rod 702 can control the distance between the back panel 6 and the first fetal position 5. The mounting plate 701 can be provided with three sleeves 7011, each corresponding to the position of the three pull cords 9. The sleeves 7011 are slidably mounted over the pull cords 9 with minimal clearance. The sleeves 7011 abut the back panel 6, while the positioning portion 7012 is inserted into the positioning hole 506, effectively achieving parallel distance between the back panel 6 and the first fetal position 5. The end of the threaded rod 702 can be rotatably connected to the middle portion of the mounting plate 701.

[0051] Three pull ropes 9 are provided, with two at intervals on the upper portion and one at the lower portion, so as to facilitate the steel pipe 1 to enter between the two positioning assemblies from above after being hoisted.

[0052] Furthermore, the lower portion of the first fetal position 5 has a vertically arranged adjustment groove 507 ; and further comprises: a bottom block 508 slidably arranged on the adjustment groove 507 , the upper end of the bottom block 508 being used to abut against the lower side of the flange 2 .

[0053] When in use, the bottom block 508 slides up and down at the lower part of the first fetal position 5 to adjust its position, and can be positioned by tightening bolts to support the flange 2. When the flange 2 of the same specification is fixed on the first fetal position 5, the bottom block 508 forms a bottom positioning support, which can more quickly connect the flange 2 to the through hole 5021 of the slider 502.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
