[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1 to Figure 2 The embodiment of the present application provides a device for assisting the turning over and lifting of steel tower segments, which can solve the problem in the related art that hoisting and flipping the steel tower segments on the supporting structure may cause deformation or instability of the steel tower segment structure, affecting construction safety and efficiency.

[0022] With the development of technology and the demand for crossing rivers, lakes and seas, more and more steel tower bridges have emerged. In order to facilitate the manufacture and transportation of steel towers, the steel tower will be divided into several steel tower segments 6, and the prefabricated steel tower segments 6 will be transported to the construction site for assembly to improve the efficiency of the steel tower construction process and shorten the construction period. During the transportation of the steel tower segment 6, considering factors such as height and width, it is necessary to transport it flat to the designed position and finally lift it vertically. According to traditional processes, directly hoisting the steel tower segment 6 on the supporting structure 5 and flipping it over not only takes a lot of time, but also the steel tower and the supporting structure 5 are locally stressed during the hoisting process, which may cause structural deformation or instability, affecting construction safety and efficiency. Therefore, it is very necessary to design a device that can pre-flip the steel tower segment 6.

[0023] Aiming at the problem that hoisting and turning over the steel tower segment 6 on the supporting structure 5 may cause deformation or instability of the steel tower segment 6 structure, affecting the construction safety and efficiency. The embodiment of the present application provides a device for assisting the turning over and hoisting of the steel tower segment, which includes: a second turning frame 2 and a first turning frame 1, wherein the first turning frame 1 is provided with an installation space for installing the steel tower segment 6, the first turning frame 1 has a first fitting surface and a second fitting surface, the first turning frame 1 is rotatably connected to the second turning frame 2, when the first fitting surface is fitted with the second turning frame 2, the steel tower segment 6 located in the installation space is horizontally arranged, and when the second fitting surface is fitted with the second turning frame 2, the steel tower segment 6 located in the installation space is vertically arranged.

[0024] In the present application, after the steel tower segment 6 is installed on the first turning frame 1, the first turning frame 1 can be rotated to drive the steel tower segment 6 to rotate 90°, ensuring that the steel tower segment 6 is adjusted from horizontal placement to vertical placement, which facilitates the lifting of the steel tower segment 6.

[0025] On the basis of the above embodiment, in this embodiment, the first turning frame 1 is rotatably connected to the second turning frame 2 via a pin shaft 3 .

[0026] Specifically, the second turning frame 2 is a supporting platform for supporting the first turning frame 1 , and a supporting leg is fixed at the bottom end of the second turning frame 2 .

[0027] In some possible embodiments, the legs are set to be fixed structures, that is, the height of the legs cannot be adjusted at will;

[0028] In some other possible embodiments, the supporting legs are set as adjustable structures. Specifically, the supporting legs can be set to include a frame body and a hydraulic cylinder, that is, the frame body is fixed between the top end of the hydraulic cylinder output shaft and the second turning frame 2. When the height of the second turning frame 2 needs to be adjusted, the hydraulic cylinder is operated, and the purpose of adjusting the height of the second turning frame 2 is achieved by extending and retracting the hydraulic cylinder output shaft.

[0029] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0030] In addition, when it is necessary to make the second turning frame 2 more convenient to move, rollers with brakes are installed at the bottom ends of the legs, and when it is necessary to transfer the second turning frame 2, the rollers are rolled.

[0031] The first turning frame 1 and the second turning frame 2 are connected by the pin shaft 3, so the first turning frame 1 can be rotated. When the first turning frame 1 is rotated until its first fitting surface is in contact with the top of the second turning frame 2, the steel tower segment 6 located in the installation space is horizontally arranged. When the first turning frame 1 is rotated until its second fitting surface is in contact with the top of the second turning frame 2, the steel tower segment 6 located in the installation space is vertically arranged.

[0032] When the first turning frame 1 is turned over, in addition to using an external device, a pulley block can also be installed on the second turning frame 2, and the pulley block is connected to the first turning frame 1 through a connecting rope. Therefore, when the pulley block controls the connection rope to be retracted or released, with the assistance of the external device, the first turning frame 1 can be turned over easily.

[0033] Furthermore, a first connecting rod is fixedly connected to the first turning frame 1, and a second connecting rod is fixedly connected to the second turning frame 2, and the pin 3 is arranged between the first connecting rod and the second connecting rod. The first connecting rod is fixedly connected to the bottom end of the first turning frame 1, and the second connecting rod is fixed to the top end of the second turning frame 2. After the pin 3 is passed through the first connecting rod and the second connecting rod, the first connecting rod can rotate relative to the second connecting rod. Therefore, when the first connecting rod rotates, the first turning frame 1 can be driven to rotate. The pin 3 is used to connect the first turning frame 1 and the second turning frame 2, and the initial posture of the first turning frame 1 is adjusted to ensure that the steel tower segment 6 can be placed horizontally, and the steel tower segment 6 is rotated 90° together with the first turning frame 1 by using the hoisting system with the pin 3 as the center of the circle, so as to ensure that the steel tower segment 6 is placed vertically.

[0034] On the basis of the above embodiment, in this embodiment, a first pad 20 is fixedly connected to the top of the second turning frame 2. The first pad 20 is located at one side of the first turning frame 1. The first pad 20 is used to fit with the first fitting surface.

[0035] In this embodiment, since the second connecting rod is fixed on the second turning frame 2, when the first turning frame 1 is turned over and the steel tower segment 6 located in the installation space is horizontally arranged, if the first pad 20 is not provided, the first contact surface in the first turning frame 1 will not contact the top of the second turning frame 2, and one side of the first turning frame 1 will be suspended in the air, which does not take advantage of the stability of the device structure. Figure 1 As shown, a first pad 20 is fixed on the top of the second turning frame 2, so that after the first turning frame 1 is turned over, it can fit with the first pad 20 to ensure that the first turning frame 1 is in a stable state.

[0036] Furthermore, a first shock-absorbing pad is provided on the first pad 20, and the first shock-absorbing pad can play a role in shock absorption when the first turning frame 1 is turned over and fits with the first pad 20. In addition, the first shock-absorbing pad can be fixed on the first fitting surface of the first turning frame 1. In this embodiment, the fixing position of the first shock-absorbing pad can be determined according to actual needs, and no specific limitation is made here.

[0037] On the basis of the above embodiment, in this embodiment, a second pad 21 is fixedly connected to the top of the second turning frame 2. The second pad 21 is located on the other side of the first turning frame 1. The second pad 21 is used to fit with the second fitting surface.

[0038] In this embodiment, since the second connecting rod is fixed on the second turning frame 2 and the first connecting rod is fixed on the first turning frame 1, when the first turning frame 1 is turned over and the steel tower segment 6 located in the installation space is set vertically, if the second pad 21 is not provided, the second contact surface in the first turning frame 1 will not contact the top of the second turning frame 2, and one side of the first turning frame 1 will be suspended in the air, which does not take advantage of the stability of the device structure. Figure 2 As shown, a second pad 21 is fixed on the top of the second turning frame 2, so that after the first turning frame 1 is turned over, it can fit with the second pad 21 to ensure that the first turning frame 1 is in a stable state.

[0039] Furthermore, a second shock-absorbing pad is provided on the second pad 21. Through the provision of the second shock-absorbing pad, when the first turning frame 1 is turned over and fits with the second pad 21, it can play a role in shock absorption. In addition, the second shock-absorbing pad can also be fixed on the second fitting surface of the first turning frame 1. In this embodiment, the fixing position of the second shock-absorbing pad can be determined according to actual needs, and no specific limitation is made here.

[0040] On the basis of the above embodiment, in this embodiment, the device further comprises a copying mat 4 , and the copying mat 4 is arranged on one side of the second turning frame 2 .

[0041] Specifically, when the first fitting surface is fitted with the second turning frame 2, the steel tower segment 6 located in the installation space is horizontally arranged; when the second fitting surface is fitted with the second turning frame 2, the steel tower segment 6 located in the installation space is vertically arranged; no matter whether the steel tower segment 6 is arranged horizontally or vertically, one side of the steel tower segment 6 is in a suspended state, so a pad 4 is arranged on one side of the second turning frame 2, and the steel tower segment 6 is supported by the pad 4, so that both ends of the steel tower segment 6 remain in a horizontal and stable state.

[0042] Furthermore, a height adjustment member is provided on the shoveling mat 4. By providing the height adjustment member, the shoveling mat 4 can be adapted to different types of steel tower segments 6, that is, no matter what type of steel tower segment 6, the height of the shoveling mat 4 can be adjusted by the height adjustment member, so that the shoveling mat 4 supports the steel tower segment 6. The height adjustment member can also be a hydraulic cylinder, and the shoveling mat 4 is connected to the output shaft of the hydraulic cylinder to meet the needs of adjusting the shoveling mat 4.

[0043] Furthermore, a third shock-absorbing pad is fixedly connected to the shoveling pad 4, and the third shock-absorbing pad is in contact with the steel tower segment 6, so that wear between the shoveling pad 4 and the steel tower segment 6 can be avoided, and shock-absorbing and buffering can be performed on the shoveling pad 4 and the steel tower segment 6 when the steel tower segment 6 is lowered.

[0044] On the basis of the above embodiment, in this embodiment, a limiting member is provided on the first turning frame 1. By providing the limiting member, the steel tower segment 6 can be temporarily fixed on the first turning frame 1, and when the first turning frame 1 drives the steel tower segment 6 to turn over, the steel tower segment 6 can be fixed.

[0045] Specifically, in some possible embodiments, the limiting member may include a hook fixed on the first turning frame 1 and a connecting rope connected to the hook, and the steel tower segment 6 is tied and fixed to the first turning frame 1 through the connecting rope;

[0046] In some other possible embodiments, the limiting member may further include a clamping claw fixed on the first turning frame 1 , and the steel tower segment 6 is clamped and fixed on the first turning frame 1 by the clamping claw.

[0047] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0048] When the device is used, firstly, the first turning frame 1 and the second turning frame 2 are assembled, and the first turning frame 1 and the second turning frame 2 are fixed on the supporting structure 5, and then the copying pad 4 is placed on the supporting structure 5, and the position of the copying pad 4 is adjusted; then the steel tower segment 6 is horizontally lifted to the turning frame and the copying pad 4 by the lifting system; then the steel tower segment 6 is turned over 90 degrees by the lifting system and the first turning frame 1; the copying pad 4 copies the turned steel tower segment 6, and finally the steel tower segment 6 is vertically lifted by the lifting system.

[0049] In summary, the device is used to flip the flat (horizontally placed) steel tower segment 6 for vertical lifting, and the tower column segment is supported and flipped by using the first turning frame 1 and the first pad 20, the second pad 21 and the pad 4, which improves the efficiency of the construction process, the construction method is simple, the operation is quick and convenient, and the practicability is strong.
