Description

Technical Field

[0001] This utility model relates to the field of tower foundation installation technology, and in particular to a lifting mechanism for tower foundation installation. Background Technology

[0002] During the installation of tower foundations, existing technologies for hoisting the outriggers mostly rely on large lifting equipment such as truck cranes and crawler cranes, or the traditional method of using a boom with guy ropes. The process typically involves first securing one end of the outrigger with clamps or ropes, then using the lifting structure of the crane to apply tension to the other end, causing the outrigger to rotate and stand upright around the fixed end. During this process, the final installation posture of the outrigger needs to be fine-tuned by moving the crane or adjusting the guy rope arrangement according to the installation location requirements.

[0003] Existing technologies have significant shortcomings in the adjustment of the outrigger installation position, specifically manifested in low adjustment efficiency. After the outrigger is initially clamped and fixed using existing lifting equipment or a boom, if a deviation in the installation position is found, it is necessary to first release the fixation of the outrigger, then move the base of the large lifting equipment as a whole, or disassemble and re-lay the guy ropes and support structure of the boom. The operation steps are cumbersome and time-consuming. Especially in narrow construction sites or areas with restricted terrain, the movement of lifting equipment is difficult, further extending the position adjustment cycle and making it difficult to meet the construction requirements of rapid tower foundation installation. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a lifting mechanism for the installation of iron tower foundations. By setting a sliding support side plate and a support inner plate on the support base and positioning them by a connecting plate, a drive component drives a clamping pad to fix one end of the iron tower arm, and then pulling the connecting rope by pulling the component to lift the other end of the arm to achieve erection. When adjusting the installation position of the arm, it is only necessary to loosen the positioning bolts to push the support side plate and the support inner plate to slide along the guide groove, without the need to move the lifting equipment as a whole or disassemble the guy ropes. This solution effectively solves the problem of low efficiency in adjusting the installation position of the arm in the prior art and is suitable for the construction needs of rapid installation of iron tower foundations.

[0006] To achieve the above objectives, this utility model proposes a lifting mechanism for installing iron tower foundations, comprising a support base, support side plates, an inner support plate, a connecting plate, a drive assembly, a mounting head, a clamping pad, and a pulling assembly. The support side plates are symmetrically slidably engaged with the top two sides of the support base, and the inner support plate is symmetrically slidably engaged with the inner wall of the support base. A connecting plate is provided between the inner wall of the support side plates and the outer wall of the inner support plate, connecting them. The drive assembly is mounted on the outer wall of the support side plates, and its output end penetrates the outer wall of the inner support plate and is rotatably connected to one end of the mounting head. The clamping pad is fixedly connected to the other end of the mounting head. The pulling assembly is mounted on one top end of the support base.

[0007] This utility model discloses a lifting mechanism for installing iron tower foundations. Based on a support base, the mechanism first pushes the support side plate and the support inner plate along the guide groove of the support base according to the boom size. The two are rigidly connected to the appropriate spacing through a connecting plate. The positioning bolts are screwed into the mounting holes to lock them in place. The first drive device of the drive assembly is activated, which drives the drive boom and support head to move. The clamping pad on the mounting head clamps one end of the boom, and the connecting rope of the winding roller in the pulling assembly is fixed to the other end of the boom. The second drive device is activated to drive the winding roller to wind up the rope. The boom stands up around the connection between the mounting head and the support head. When adjusting the position, only the positioning bolts need to be loosened to slide the support side plate and the support inner plate. There is no need to move large equipment or disassemble the guy ropes, which effectively solves the problem of low efficiency in boom installation and adjustment in the prior art.

[0008] In addition, the lifting mechanism for installing iron tower foundations proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the drive assembly includes a first drive device, a drive arm, and a support head. The first drive device is installed on the outer wall of the support side plate. The output end of the first drive device passes through the outer wall of the support side plate and is fixedly connected to one end of the drive arm. The other end of the drive arm passes through the outer wall of the inner support plate and is fixedly connected to one end of the support head. One end of the mounting head is rotatably connected to the other end of the support head.

[0010] Specifically, the pulling assembly includes an assembly base, a second drive device, a take-up roller, and a connecting rope. The assembly base is fixedly connected to one top end of the support base. The second drive device is installed on the outer wall of the assembly base. The take-up roller is rotatably connected to the inner wall of the assembly base. The output end of the second drive device is fixedly connected to one end of the take-up roller. One end of the connecting rope is sleeved on the take-up roller.

[0011] Specifically, the top of the connecting plate is threaded with a positioning bolt, and the top of the support base is provided with mounting holes at equal intervals that match the positioning bolt.

[0012] Specifically, the top of the support base and both sides of the inner wall are provided with guide grooves that match the bottom of the support side plate and the outer wall of the support inner plate.

[0024] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The following description, in conjunction with the accompanying drawings, describes a crane mechanism for installing iron tower foundations according to an embodiment of this utility model.

[0026] like Figures 1-4 As shown, the lifting mechanism for installing the iron tower foundation in this embodiment of the present utility model may include a support base 1, a support side plate 2, a support inner plate 3, a connecting plate 4, a drive assembly 5, a mounting head 6, a clamping pad 7, and a pulling assembly 8.

[0027] Among them, the supporting side plate 2 is symmetrically slidably snapped onto the top two sides of the supporting base 1, the supporting inner plate 3 is symmetrically slidably snapped onto the inner wall of the supporting base 1, and a connecting plate 4 is provided between the inner wall of the supporting side plate 2 and the outer wall of the supporting inner plate 3, and they are connected by the connecting plate 4.

[0028] It should be noted that, in this embodiment, the support side plate 2 and the support inner plate 3 are respectively connected to the support base 1 through a sliding snap-fit ​​structure, which can ensure that the two move along a fixed trajectory and avoid deviation or misalignment during the sliding process. The connecting plate 4 rigidly connects the support side plate 2 and the support inner plate 3, which can realize the synchronous sliding of the two and ensure the centering when clamping the support arm. At the same time, this double-layer plate design can also enhance the load-bearing capacity of the overall structure and prevent the support side plate 2 or the support inner plate 3 from deforming due to the large weight of the support arm, further improving the stability of clamping and fixing.

[0029] The drive assembly 5 is installed on the outer wall of the support side plate 2, and the output end of the drive assembly 5 passes through the outer wall of the support inner plate 3 and is rotatably connected to one end of the mounting head 6. The clamping pad 7 is fixedly connected to the other end of the mounting head 6.

[0030] It should be noted that the drive component 5 described in this embodiment is installed on the outer wall of the support side plate 2. This not only facilitates the inspection and maintenance of the drive component 5 in the later stage, but also avoids it occupying the internal space of the support base 1 and reduces interference with other structures. The design of the output end of the drive component 5 penetrating through the inner support plate 3 can form auxiliary support for the output end through the inner support plate 3, preventing the output end from shaking during the drive clamping process. The rotational connection between the mounting head 6 and the output end allows the support arm to rotate adaptively with the angle change when it is pulled up, avoiding rigid friction between the support arm and the clamping pad 7. The clamping pad 7 can increase the friction with the surface of the support arm, preventing the support arm from slipping during clamping or rotation, and at the same time, it can also protect the surface of the support arm to avoid damaging the support arm.

[0031] The pull assembly 8 is installed at the top end of the support base 1.

[0032] It should be noted that the pulling component 8 described in this embodiment is installed at one end of the top of the support base 1, which allows the connecting rope 84 of the pulling component 8 to form a more reasonable force angle with the end of the outrigger to be pulled up, reducing the loss of pulling force during transmission and improving the efficiency of the outrigger to be pulled up. At the same time, this installation position allows the pulling component 8 to cooperate with the clamping structure, avoiding spatial interference between the two during operation. In addition, integrating the pulling component 8 onto the support base 1 eliminates the need for a separate installation foundation, simplifying the overall equipment deployment process and making it easy to move with the support base 1 as a whole, adapting to different construction scenarios.

[0033] Specifically, before the operation, according to the size of the tower outrigger to be installed, push the symmetrically sliding support side plates 2, which are locked to the top of the support base 1, and the symmetrically sliding support inner plates 3, which are locked to the inner walls of the support base 1. Since the support side plates 2 and the support inner plates 3 are rigidly connected by the connecting plate 4, they can slide synchronously along the guide groove of the support base 1 and along a fixed trajectory. After adjusting to the appropriate spacing for the outrigger clamping, the positioning bolts 41 on the connecting plate 4 are screwed into the mounting holes 11 of the support base 1 to lock them in place. Then, the drive assembly 5 installed on the outer wall of the support side plate 2 is activated. Its output end passes through the support inner plate 3 and drives the mounting head 6 to move, so that the clamping pad 7 fixed at the other end of the mounting head 6 tightly clamps one end of the outrigger. Then, the connecting rope 84 on the winding roller 83 in the pulling assembly 8 installed at one end of the top of the support base 1 is fixed to the other end of the outrigger. The second drive device 82 of the pulling assembly 8 is activated to drive the winding. Roller 83 rotates and winds up connecting rope 84, applying tension to the other end of the support arm. At this time, the clamped end of the support arm will adaptively rotate around the rotational connection between the mounting head 6 and the output end of the drive assembly 5, gradually rising from a horizontal or inclined state. When it is necessary to adjust the installation position of the support arm, there is no need to release the clamping and fixing of the support arm, nor is it necessary to move the lifting equipment as a whole or disassemble the guy rope. It is only necessary to loosen the positioning bolt 41 on the connecting plate 4 and push the support side plate 2 and the support inner plate 3 to slide synchronously along the guide groove of the support base 1. This will drive the clamped support arm to move to the target position along with the clamping structure. Locking the positioning bolt 41 again will complete the position adjustment. This process effectively solves the problem of low efficiency caused by the need to move large equipment or disassemble auxiliary structures for position adjustment in the existing tower support arm installation technology in the background technology. It greatly simplifies the adjustment operation, shortens the adjustment cycle, and adapts to the construction needs of rapid installation of tower foundations.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, the drive assembly 5 includes a first drive device 51, a drive arm 52, and a support head 53. The first drive device 51 is installed on the outer wall of the support side plate 2. The output end of the first drive device 51 passes through the outer wall of the support side plate 2 and is fixedly connected to one end of the drive arm 52. The other end of the drive arm 52 passes through the outer wall of the support inner plate 3 and is fixedly connected to one end of the support head 53. One end of the mounting head 6 is rotatably connected to the other end of the support head 53.

[0035] It should be noted that the drive assembly 5 described in this embodiment forms a stable power transmission path through the three-section connection of the first drive device 51, the drive arm 52 and the support head 53. The first drive device 51 is installed on the outer wall of the support side plate 2, which is convenient for later maintenance and avoids occupying the internal space of the support base 1. The design of the drive arm 52 penetrating through the inner support plate 3 can form radial support for the drive arm 52 with the help of the inner support plate 3, preventing the drive arm 52 from bending and deforming when pushing the support head 53. The rotational connection between the support head 53 and the mounting head 6 provides flexible rotation space for the mounting head 6, avoiding rigid compression between the support arm and the clamping pad 7 during the lifting process. The first drive device 51 is a hydraulic cylinder.

[0036] Specifically, when clamping the tower outrigger, the first drive device 51 is activated, and its output end drives the drive arm 52 to extend and retract in the horizontal direction. The drive arm 52 then pushes the support head 53 to move towards the outrigger, so that the clamping pad 7 fixed on the mounting head 6 tightly adheres to the surface of the outrigger to complete the clamping. When the pulling component 8 pulls the other end of the outrigger to stand up, the outrigger will drive the mounting head 6 to rotate around the support head 53. There is no need to manually adjust the clamping angle, which avoids the problem of wear on the outrigger surface or loosening of the clamp due to the fixed clamping angle in the prior art. At the same time, the rotation and standing of the outrigger can be achieved without disassembling the drive structure, which greatly simplifies the operation process and solves the problem of low efficiency in outrigger installation and adjustment in the background art.

[0037] In one embodiment of this utility model, such as Figures 1-4 As shown, the pulling assembly 8 includes an assembly base 81, a second drive device 82, a take-up roller 83, and a connecting rope 84. The assembly base 81 is fixedly connected to one end of the top of the support base 1. The second drive device 82 is installed on the outer wall of the assembly base 81. The take-up roller 83 is rotatably connected to the inner wall of the assembly base 81, and the output end of the second drive device 82 is fixedly connected to one end of the take-up roller 83. One end of the connecting rope 84 is sleeved on the take-up roller 83.

[0038] It should be noted that the pulling component 8 described in this embodiment is integrated on the support base 1 through the mounting base 81, eliminating the need to build a separate installation foundation for the pulling component 8, thus simplifying the overall setup steps of the equipment. The design of the connecting rope 84 being sleeved on the take-up roller 83 allows for the orderly winding and unwinding of the connecting rope 84 through the rotation of the take-up roller 83, preventing the connecting rope 84 from getting tangled and knotted, which would affect work efficiency. The second driving device 82 is a drive motor.

[0039] Specifically, when raising the tower outrigger, the free end of the connecting rope 84 is first fixed to the end of the outrigger to be raised. Then, the second drive device 82 is activated, and its output end drives the winding roller 83 to rotate on the inner wall of the mounting base 81. During the rotation of the winding roller 83, the connecting rope 84 is gradually wound onto the roller body. The connecting rope 84 then applies an upward pulling force to the outrigger, causing the outrigger to stand up around the rotation point of the mounting head 6 and the support head 53. Since the pulling component 8 is integrated on the support base 1, it can move as a whole with the support base 1. Unlike the prior art, there is no need to adjust the position of the lifting equipment separately, nor is it necessary to disassemble and re-lay the guy ropes. This effectively solves the problem of cumbersome and inefficient position adjustment after the outrigger is raised in the background art.

[0040] In one embodiment of this utility model, such as Figures 1-4 As shown, the top of the connecting plate 4 is threaded with a positioning bolt 41, and the top of the support base 1 is provided with mounting holes 11 at equal intervals that match the positioning bolt 41.

[0041] It should be noted that the threaded engagement between the positioning bolt 41 and the mounting hole 11 described in this embodiment can form a firm locking effect, preventing the support side plate 2 and the support inner plate 3 from loosening or shifting during the clamping of the support arm or adjustment of its position. The design of the mounting holes 11 being opened at equal intervals allows for flexible selection of the installation position of the positioning bolt 41 according to the different dimensions of the tower support arm.

[0042] In one embodiment of this utility model, such as Figures 1-4 As shown, the top and both sides of the inner wall of the support base 1 are provided with guide grooves that match the bottom of the support side plate 2 and the outer wall of the support inner plate 3.

[0043] It should be noted that the matching design of the guide groove with the bottom of the support side plate 2 and the outer wall of the support inner plate 3 described in this embodiment can provide a fixed trajectory for the sliding of the support side plate 2 and the support inner plate 3, prevent the two from deviating or misaligning during the sliding process, and ensure that the support side plate 2 and the support inner plate 3 always maintain a symmetrical state, thereby ensuring that the clamping force of the clamping pad 7 on the support arm is uniform. At the same time, the guide groove can also form a vertical limit on the support side plate 2 and the support inner plate 3, preventing them from tilting upwards when bearing the weight of the support arm.

[0044] In summary, the lifting mechanism for tower foundation installation of this utility model embodiment, based on the support base 1, first pushes the support side plate 2 and the support inner plate 3 along the guide groove of the support base 1 according to the size of the support arm, and rigidly connects them to the appropriate spacing through the connecting plate 4. The positioning bolt 41 is screwed into the mounting hole 11 to lock them. The first driving device 51 of the driving assembly 5 is started, which drives the driving arm 52 and the support head 53 to move, so that the clamping pad 7 on the mounting head 6 clamps one end of the support arm. The connecting rope 84 of the winding roller 83 in the pulling assembly 8 is fixed to the other end of the support arm. The second driving device 82 is started to drive the winding roller 83 to wind the rope. The support arm is erected around the connection between the mounting head 6 and the support head 53. When adjusting the position, it is only necessary to loosen the positioning bolt 41 to slide the support side plate 2 and the support inner plate 3. There is no need to move large equipment or disassemble the guy ropes, which effectively solves the problem of low efficiency in support arm installation and adjustment in the background art.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
