Description

Technical Field

[0001] The invention belongs to the technical field of bridge steel structure installation, and particularly relates to a positioning locking device, a fixing method and an installation method for steel tower segment installation. Background Art

[0002] Bridges are the link and throat of traffic development and a "shortcut" to accelerate economic development. The proportion of steel structure bridges in all bridges is increasing day by day. Among them, steel structure towers are increasingly widely used due to their light weight, short construction period and environmental protection. At the same time, in order to pursue architectural beauty, arc-shaped and special-shaped components are used in bridge tower structures instead of straight-shaped components. Compared with straight-shaped components, the installation accuracy of special-shaped components is more difficult to control. How to ensure the accuracy and reliability of the installation of large special-shaped bridge tower components has become a difficulty in bridge construction.

[0003] At present, domestic steel tower segment installation usually adopts jack to adjust the position of the docking interface, which takes a long time to position and is difficult to ensure the positioning accuracy. After the steel tower segment is in place, the lifting method of loosening the hook after welding reinforcement is adopted. The welding reinforcement process takes a long time and occupies a long time of crane, resulting in high installation cost and low efficiency. Summary of the invention

[0004] In view of the above-mentioned technical status quo, the present invention provides a positioning and locking device for the installation of steel tower segments, which integrates the positioning function and the locking function, can quickly realize the positioning and locking of the docked steel tower segments, ensure the precise and rapid spatial positioning and rapid fixation of the docked steel tower segments, and can be used for the docking of large special-shaped steel tower components.

[0005] The technical solution provided by the present invention is: a positioning and locking device for steel tower segment installation, comprising a first positioning part fixed to a first steel tower segment, a second positioning part fixed to a second steel tower segment, and a locking part;

[0006] The first positioning part includes two first clamping plates A and B that are parallel to each other and spaced apart from each other, one end of the first clamping plate A and one end of the first clamping plate B are respectively fixedly connected to one side of the first limiting plate A; the first limiting plate A, the first clamping plate A and the first clamping plate B form a first groove structure;

[0007] The second positioning part includes two second clamping plates A and B that are parallel to each other and spaced apart from each other, one end of the second clamping plate A and one end of the second clamping plate B are respectively fixedly connected to one side of the second limiting plate A; the second limiting plate A, the second clamping plate A and the second clamping plate B form a second groove structure;

[0008] The locking part includes a first through hole A, a second through hole A, a connecting rod, a first fixing member and a second fixing member; the first through hole A is arranged on the first limiting plate A, and the second through hole A is arranged on the second limiting plate A;

[0009] The first groove can be inserted into the second groove opposite to the second groove opening and along the depth direction of the second groove; one end of the connecting rod can pass through the first through hole A and be fixed by the first fixing member, and the other end of the connecting rod can pass through the second through hole A and be fixed by the second fixing member.

[0010] Preferably, the depth of the second groove is less than or equal to the depth of the first groove.

[0011] In order to improve the locking effect, preferably, the other side of the first limiting plate A is fixedly connected to one end of the first stiffening plate A and one end of the first stiffening plate B, the first stiffening plate A and the first stiffening plate B are parallel to each other and there is a gap between them, the other end of the first stiffening plate A and the other end of the first stiffening plate B are fixedly connected to one side of the first limiting plate B; the first limiting plate B is provided with a first through hole B; one end of the connecting rod can pass through the first through hole A and the first through hole B, and is fixed to the other side of the first limiting plate B through the first fixing member.

[0012] In order to improve the locking effect, preferably, the other side of the second limiting plate A is fixedly connected to one end of the second stiffening plate A and one end of the second stiffening plate B, the second stiffening plate A and the second stiffening plate B are parallel to each other and there is a gap between them, the other end of the second stiffening plate A and the other end of the second stiffening plate B are fixedly connected to one side of the second limiting plate B; the second limiting plate B is provided with a second through hole B; the other end of the connecting rod can pass through the second through hole A and the second through hole B, and is fixed to the other side of the second limiting plate B through the second fixing member.

[0013] Preferably, the connecting rod is a high-strength screw rod, one end of which is provided with a first thread structure, and the other end is provided with a second thread structure, the first fixing member is a first nut structure matching the first thread structure, and the second fixing member is a second nut structure matching the second thread structure. Further preferably, the first nut structure is composed of a first flat nut and a first nut, and the second nut structure is composed of a second flat nut and a second nut.

[0014] In order to facilitate the insertion of the first groove into the second groove, it is preferable that the cross-sectional area of ​​the first card plate A and the first card plate B in the first groove (the cross-sectional area refers to the cross-sectional area parallel to the bottom of the first groove) gradually decreases from the bottom of the first groove to the open end. As an implementation method, in the longitudinal cross-section of the first card plate A and the first card plate B (the longitudinal cross-section refers to the cross-sectional area perpendicular to the bottom of the first groove), the end away from the bottom of the first groove is a trapezoidal structure. In order to facilitate the first steel tower segment and the second steel tower segment to be combined at the interface without interference and to achieve precise joining, preferably, the first card plate A and the first card plate B are provided with a recessed structure at the interface between the first steel tower segment and the second steel tower segment, thereby avoiding the interface between the first steel tower segment and the second steel tower segment.

[0015] At present, the device for positioning the steel tower segment is generally only set on the inner wall or outer wall of the steel tower segment. Considering that the thickness of the steel tower segment from the inner wall to the outer wall is relatively large, if the positioning device is only set on a single side wall (inner wall or outer wall) of the steel tower segment, it may cause that although the side wall (inner wall or outer wall) where the positioning device is set has been positioned, the other side wall (when the positioning device is set on the inner wall, the other side wall refers to the outer wall; when the positioning device is set on the outer wall, the other side wall refers to the inner wall) still has a misalignment problem, thereby affecting the precise positioning of the steel tower segment. To this end, the present invention designs the first positioning part to be two sets, which are symmetrically arranged on the inner wall and the outer wall of the first steel tower segment respectively; the second positioning part is two sets, which are symmetrically arranged on the inner wall and the outer wall of the second steel tower segment respectively, so as to achieve precise positioning between the inner and outer walls of the first steel tower segment and the second steel tower segment.

[0016] The present invention also provides a method for fixing the positioning locking device, which is as follows:

[0017] A first positioning part is fixed on a single side wall (inner wall or outer wall) or double side walls (inner wall and outer wall) of the first steel tower segment, and a second positioning part is fixed on the same side wall of the second steel tower segment (if the first positioning part is fixed on the inner wall of the first steel tower segment, the same side wall is the inner wall; if the first positioning part is fixed on the outer wall of the first steel tower segment, the same side wall is the outer wall; if the first positioning part is fixed on both the inner wall and the outer wall of the first steel tower segment, the same side wall is the inner wall and the outer wall), so that the first positioning part and the second positioning part are distributed on both sides of the interface, so that the first groove can be inserted into the second groove along the depth direction of the second groove opposite to the opening of the second groove, and the first through hole A corresponds to the second through hole A in position, so that one end of the connecting rod can pass through the first through hole A and the second through hole A.

[0018] In order to ensure the accuracy of positioning, the first steel tower segment and the second steel tower segment are fixed with a first positioning part and a second positioning part when they are assembled in a factory.

[0019] The fixing method is not limited, but is preferably fixed by welding.

[0020] Preferably, when the first steel tower segment fixes the first positioning part, the following steps are specifically included:

[0021] (1) Fix the first clamping plate A and the first clamping plate B on the first steel tower segment;

[0022] (2) The first limiting plate A is fixed to one end of the first clamping plate A and one end of the first clamping plate B, so that the first clamping plate A and the first clamping plate B are located on one side of the first limiting plate A.

[0023] When the first stiffening plate A, the first stiffening plate B and the first limit plate B are preferably provided, the following steps (3) and (4) are also included:

[0024] (3) Fix one end of the first clamping plate A and one end of the first clamping plate B on the other side of the first limiting plate A;

[0025] (4) Fix the first limiting plate B at the other end of the first clamping plate A and the other end of the first clamping plate B.

[0026] Preferably, when the second steel tower segment fixes the second positioning part, the following steps are specifically included:

[0027] (1) Fix the second clamping plate A and the second clamping plate B on the outer wall of the second steel tower segment;

[0028] (2) The second limiting plate A is fixed to one end of the second clamping plate A and one end of the second clamping plate B, so that the second clamping plate A and the second clamping plate B are located on one side of the second limiting plate A.

[0029] When the second stiffening plate A, the second stiffening plate B and the second limiting plate B are preferably provided, the following steps (3) and (4) are also included:

[0031] (4) Fix the second limiting plate B at the other end of the second clamping plate A and the other end of the second clamping plate B.

[0032] The present invention also provides a method for installing a steel tower segment using the positioning locking device, which is specifically as follows:

[0033] (1) Under the action of external force, the interface sides of the first steel tower segment and the second steel tower segment are close to each other;

[0034] (2) the first groove is inserted into the second groove along the depth direction of the second groove, with the opening of the first groove facing the second groove;

[0036] Preferably, the external force is removed after completing step (3).

[0037] The external force is not limited. When the hoisting method is adopted, the external force is the pulling force of the crane.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The positioning locking device of the present invention integrates the positioning function and the locking function into one, thereby realizing positioning locking.

[0040] (2) The present invention designs a first groove structure and a second groove structure, and realizes rapid positioning of the steel tower segment by inserting the first groove into the second groove, and designs at least two through holes and connecting rods, and locks the steel tower segment by passing the connecting rods through the through holes, thereby realizing rapid locking and improving the installation efficiency of the steel tower segment.

[0041] (3) The present invention is preferably designed such that the cross-sectional areas of the first card plate A and the first card plate B in the first groove gradually decrease from the bottom of the first groove to the open end, thereby facilitating rapid insertion of the first groove into the second groove and further improving installation efficiency.

[0076] In this embodiment, Figure 5 As shown, the installation method of the positioning locking device is as follows:

[0077] A first positioning part 10 is installed on the outer wall of the first steel tower segment 100, and a second positioning part 20 is installed on the outer wall of the second steel tower segment 200, so that the first positioning part 10 and the second positioning part 20 are distributed on both sides of the interface position 300 between the first steel tower segment 100 and the second steel tower segment 200, so that the first groove can be inserted into the second groove along the depth direction of the second groove opposite to the opening of the second groove, and the positions of the first through hole A34, the first through hole B35, the second through hole A36, and the second through hole B37 correspond, so that one end of the connecting rod 31 can pass through the first through hole B35, the first through hole A34, the second through hole A36, and the second through hole B37 in sequence, or pass through the second through hole B37, the second through hole A36, the first through hole A34, and the first through hole B35 in sequence.

[0078] When the first positioning part 10 is installed on the outer wall of the first steel tower segment 100, the following steps are specifically included:

[0079] (1) Welding and fixing the first clamping plate A11 and the first clamping plate B12 on the outer wall of the first steel tower segment 100;

[0080] (2) Welding and fixing one side of the first limiting plate A13 to one end of the first clamping plate A11 and one end of the first clamping plate B12;

[0081] (3) Weld and fix one end of the first stiffening plate A15 and one end of the first stiffening plate B16 on the other side of the first limiting plate A13;

[0082] (4) The first limiting plate B14 is welded and fixed to the other end of the first stiffening plate A15 and the other end of the first stiffening plate B16.

[0083] When the second positioning part 20 is installed on the outer wall of the second steel tower segment 200, the following steps are specifically included:

[0084] (1) Welding and fixing the second clamping plate A21 and the second clamping plate B22 on the outer wall of the second steel tower segment 200;

[0085] (2) One end of the second clamping plate A21 and one end of the second clamping plate B22 are welded and fixed to one side of the second limiting plate A23;

[0086] (3) Weld and fix one end of the second stiffening plate A25 and one end of the second stiffening plate B26 on the other side of the second limiting plate A23;

[0087] (4) The second limiting plate B24 is welded and fixed to the other end of the second stiffening plate A25 and the other end of the second stiffening plate B26.

[0088] In this embodiment, in order to ensure the accuracy of positioning, Figure 6As shown, the first steel tower segment 100 and the second steel tower segment 200 are assembled as a whole component in the factory. During the assembly, the outer wall of the first steel tower segment 100 and the outer wall of the second steel tower segment 200 are marked to determine the position, and the first positioning part 10 and the second positioning part 20 are installed at the marked position to ensure the accuracy of the connection between the segments. This embodiment adopts hoisting, the first steel tower segment 100 is the hoisting segment, and the second steel tower segment 200 is the installed segment. Under the action of the crane, the hoisting segment is firstly moved closer to the installed segment (i.e. hoisted in place), and then the first groove is inserted into the second groove along the depth direction of the second groove relative to the opening of the second groove to complete the positioning (i.e. rough adjustment of the component), and then one end of the connecting rod 31 passes through the first perforation B, the first perforation A, the second perforation A, and the second perforation B in sequence, and one end of the connecting rod 31 is fixed by the first flat nut 321 and the first nut 322, wherein the first flat nut 321 mainly bears the shear force and plays a deformation role. When tightened according to the specified torque, the supporting surface of the first flat nut 321 is subjected to a reaction force, causing the upper half of the first nut to shrink inward and tightly hold the first thread, playing a locking and anti-loosening role. Similarly, the other end of the connecting rod is fixed by the second flat nut 323 and the second nut 324. The crane can be released after the connecting rod 31 is fixed, and then the interface welding can be performed.
