As the power generation is becoming more and more refined, increasing the tower height is considered to be a direct and effective means to increase power generation in low wind speed areas.

[0003] At present, concrete towers are generally composed of multiple concrete segments. When installing, two segments are usually placed on a mounting base at intervals by hoisting, the two segments are connected by bolts, and the two segments are pulled together by the force generated by tightening the bolts. However, due to the heavy weight of the concrete segments, this method is time-consuming and labor-intensive, and is not conducive to the rapid construction of the concrete tower.

[0004] Therefore, there is an urgent need for a concrete tower tube segment splicing connection structure that can quickly connect concrete tube segments. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a concrete tower segment splicing connection structure, which can guide the later hoisted segment to fall and approach the previously hoisted segment through a guide connection component, thereby realizing rapid connection of the concrete segments.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a concrete tower tube segment splicing connection structure, which utilizes the deadweight of the tube segment to guide the later hoisted tube segment through connecting rods and guide grooves, thereby realizing the rapid connection of the concrete tube segment.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please refer to Figure 1-6The concrete tower tube segment splicing connection structure disclosed in the embodiment of the present invention comprises: a guide connection assembly, the guide connection assembly comprises a connecting rod 1 and a guide groove 2, the guide groove 2 is used to accommodate the connecting rod 1, the connecting rod 1 and the guide groove 2 are respectively arranged on two opposite side walls of the left and right adjacent tube segments 3, wherein the extending direction of the connecting rod 1 is inclined downward, the opening direction of the guide groove 2 is inclined upward, the extending direction of the connecting rod 1 matches the opening direction of the guide groove 2, so as to ensure that the connecting rod 1 can enter the guide groove 2, and the connecting rod 1 and the guide groove 2 are slidably matched; taking the guide groove 2 being arranged on the side wall of the tube segment 3 that is first hoisted to the mounting seat as an example, when hoisting, the previous tube segment 3 is first hoisted to the mounting seat On, and preliminarily fix the previous pipe segment 3, then hoist the rear pipe segment 3 to the side of the previous pipe segment 3, and insert the connecting rod 1 of the rear pipe segment 3 into the guide groove 2 of the previous pipe segment 3, and then slowly lower the rear pipe segment 3, the connecting rod 1 can be gradually inserted into the guide groove 2 under the action of gravity, and under the action of the guide groove 2 and the connecting rod 1, the rear pipe segment 3 falls while approaching the previous pipe segment 3, and finally falls onto the mounting seat. At this time, the hoisting force is removed, and under the action of gravity, the pipe segment 3 will no longer move up and down. At this time, under the action of the guide groove 2 and the connecting rod 1, the two adjacent pipe segments 3 on the left and right can be prevented from having a relative displacement in the horizontal direction, thereby realizing the rapid connection of the concrete pipe segments 3.

[0031] As a preferred embodiment, it also includes an elastic seal 4, which is arranged between two adjacent side walls of the pipe segment 3; under the action of the guide groove 2 and the connecting rod 1, the gravity of the pipe segment 3 can be converted into a force that pushes the two adjacent pipe segments 3 to approach each other, thereby utilizing the gravity of the pipe segment 3 to squeeze the elastic seal 4 arranged between the two adjacent pipe segments 3, so as to achieve the sealing of the gap between the two pipe segments 3.

[0032] It can be understood that: since the elastic seal 4 still has a certain thickness after compression, in order to avoid the problem that the rear pipe segment 3 cannot continue to produce horizontal displacement after the elastic seal 4 is compressed, which causes the rear pipe segment 3 to be unable to fall onto the mounting seat normally, in actual use, when setting the guide groove 2 and the connecting rod 1, the setting heights of the two can be adjusted as needed to ensure that after the elastic seal 4 is compressed, the rear pipe segment 3 just falls onto the mounting seat.

[0033] Preferably, a mounting groove 5 for mounting an elastic seal 4 is provided on the side wall of at least one pipe segment 3, and the depth of the mounting groove 5 is less than the thickness of the elastic seal 4 in a natural state. As the two pipe segments 3 continue to approach each other, the elastic seal 4 can be gradually compressed into the mounting groove 5, thereby ensuring the sealing effect of the elastic seal 4 without affecting the normal installation of the two pipe segments 3.

[0034] As a preferred embodiment, the connection structure also includes a reinforcing rod 6. A first mounting hole 7 is opened on the opposite side walls of the two adjacent pipe segments 3 on the left and right. The axis of the first mounting hole 7 is perpendicular to the side wall of the pipe segment 3. The first mounting hole 7 penetrates the pipe segment 3 along the axial direction. The two ends of the reinforcing rod 6 are respectively installed in the first mounting holes 7 of the two pipe segments 3. The reinforcing rod 6 can further strengthen the connection strength between the two pipe segments 3.

[0035] What those skilled in the art can understand is that: when all other segments 3 on the same horizontal plane are installed in place, and only the last segment 3 is left to be installed, the gap left between the installed segments 3 can just accommodate the last segment 3. Taking five segments 3 in the same horizontal plane as an example, when the first four segments 3 are installed in place, the gap between the first segment 3 and the fourth segment 3 can just accommodate the fifth segment 3. At this time, the side wall of the fifth segment 3 and the surface opposite to the side wall of the fifth segment 3 no longer need to be provided with guide grooves 2 and connecting rods 1. The fifth segment 3 can be directly hoisted into place, and the five segments 3 can be spliced ​​into a complete cylindrical shape. Finally, the connection between the fifth segment 3 and the segments 3 on both sides of it can be constructed by reinforcing rods 6.

[0036] More preferably, the reinforcing rod 6 is a rod with a threaded structure on both end side walls, and the length of the reinforcing rod 6 is greater than the axial length of the first mounting hole 7. The two adjacent left and right pipe segments 3 can be connected together by a nut matching the threaded structure.

[0037] Furthermore, the extending direction of the gap between two adjacent segments 3 is the same as the extending direction of a certain diameter of the concrete tower tube formed by the multiple segments 3 .

[0038] As a preferred embodiment, in order to make the connecting rod 1 easier to enter the guide groove 2, the free end of the connecting rod 1 is a frustum-shaped structure, where the free end refers to the end of the connecting rod 1 away from the pipe segment 3 on which the connecting rod 1 is installed.

[0039] Furthermore, the opening end of the guide groove 2 is a rounded structure. By performing a rounding process on the opening of the guide groove 2 to form a rounded structure, the connecting rod 1 can enter the guide groove 2 more easily.

[0040] As a preferred embodiment, the connection structure also includes an upper and lower connecting rod 8, and a second mounting hole 9 is opened on the opposite side walls of the two adjacent upper and lower pipe segments 3, and the axis of the second mounting hole 9 is perpendicular to the side wall. Auxiliary mounting grooves 10 are opened on the arc surfaces of the upper and lower adjacent pipe segments 3, and the auxiliary mounting grooves 10 are opened on the extension path of the second mounting hole 9. The upper and lower connecting rods 8 pass through the auxiliary mounting grooves 10 and are installed in the second mounting holes 9, and the two ends of the upper and lower connecting rods 8 are respectively installed in the second mounting holes 9 of the two pipe segments 3; the upper and lower connecting rods 8 can achieve a tight connection between the two adjacent upper and lower pipe segments 3.

[0041] Preferably, the upper and lower connecting rods 8 are rods with external threads on the side walls at both ends. The length of the upper and lower connecting rods 8 is greater than the length of the second mounting hole 9. The two adjacent upper and lower pipe segments 3 can be connected together by nuts matching the external threads.

[0042] As a preferred embodiment, a casting hole 11 is opened on the pipe segment 3 provided with the guide groove 2, and the casting hole 11 is connected to the bottom of the guide groove 2. Cement can be poured into the gap between the guide groove 2 and the connecting rod 1 through the casting hole 11 to improve the overall strength of the pipe segment 3.

[0043] Preferably, the casting hole 11 is opened at the upper part of the pipe segment 3 , and the extension path of the casting hole 11 partially overlaps with the extension path of the guide groove 2 .

[0044] As a preferred embodiment, it also includes a lifting connector, one end of which is detachably connected to the pipe segment 3, and the other end of the lifting connector is provided with a lifting ear for connecting to the lifting equipment. After the lifting is completed, the lifting connector can be removed from the pipe segment 3 to prevent the lifting connector from affecting the normal installation of the concrete tower.

[0045] Adaptive changes made according to actual needs are all within the protection scope of the present invention.
