Description

Technical Field

[0001] This utility model relates to the field of wind turbine concrete tower installation technology, specifically to a segmented prestressed concrete tower segment transportation and fixing device. Background Technology

[0002] In recent years, with the promotion of prefabricated concrete technology in my country, the application of prefabricated concrete towers has become increasingly common in the field of wind power generation. This effectively makes up for the shortcomings of low rigidity and small diameter of flexible steel towers. Generally speaking, concrete towers are divided into multiple sections along the height of the tower. Each section is spliced ​​on-site by 4, 6, or 8 prefabricated concrete segments. The segments are generally arc-shaped. The segments are usually transported to the site for splicing by trailers. When the segments are hoisted onto the trailer, the arc ends of two segments are usually placed opposite each other. Then, wooden blocks or other materials are placed on the top of the segments, and steel cables and ropes are used to fix the segments to the trailer. However, the segments rely on their weight to be placed on the trailer bed. Although steel cables and other fixation are used, during transportation, the road surface is bumpy, and the two sets of segments are prone to friction and collision, causing damage to the segments.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] In one embodiment, see Figure 1 The present invention relates to a segmented prestressed concrete tower segment transportation and fixing device, comprising an upper fixing component, a lower fixing component, and a connecting component.

[0024] The upper fixing assembly includes multiple sets of snap-fit ​​parts 1 that snap onto the tunnel segment, and locking parts 2 set on the snap-fit ​​parts 1. The snap-fit ​​parts 1 are provided with snap-fit ​​grooves 3 and connecting posts 4 that are movably provided on the snap-fit ​​parts 1. The locking parts 2 are provided with locking plates 5 that are connected to the connecting posts 4. The locking parts 2 rotate under the action of external force, causing the locking plates 5 to move in opposite directions, thereby driving the snap-fit ​​parts 1 to move in opposite directions. The lower fixing assembly includes a bearing part 6 set on the upper end of the tunnel segment, a tightening part 7 that is rotatably set on the bearing part 6, and two sets of abutting parts 8 that are movably set on the tightening part 7. The bearing part 6 is provided with a protective sleeve 9, and a limiting rod 10 is provided between the bearing part 6 and the abutting parts 8. The tightening part 7 rotates under the action of external force, thereby driving the abutting parts 8 to move in opposite directions. The connecting assembly includes a connecting steel cable 11, the two ends of which are detachably connected to the snap-fit ​​parts 1, the bearing part 6, and the external transportation equipment, respectively.

[0025] Further, see Figure 2 , 3 The snap-fit ​​component 1 includes a snap-fit ​​sleeve 101, on which a first connecting ring 12 is provided, and a connecting post 4 is provided on the snap-fit ​​sleeve 101.

[0026] Preferably, the snap-fit ​​sleeve 101 has a "U" shaped structure, and the hollow interior of the snap-fit ​​sleeve 101 forms a snap-fit ​​groove 3. The top of the connecting sleeve is provided with a rotating hole 13, and the connecting post 4 is rotatably connected to the rotating hole 13.

[0027] Preferably, the first connecting ring 12 is disposed on the side wall of the connecting sleeve.

[0028] Further, see Figure 2 The locking component 2 includes a locking stud 201 and two sets of locking plates 5. The locking stud 201 is connected to the two sets of locking plates 5 by threads. The locking stud 201 is connected to one set of locking plates 5 by a positive thread, and the locking stud 201 is connected to the other set of locking plates 5 by a negative thread.

[0029] Preferably, one set of locking plates 5 is provided with a positive thread screw hole 14, and the other set of locking plates 5 is provided with a negative thread screw hole 15.

[0030] Preferably, the outer wall of the locking stud 201 is provided with external threads that match the positive thread and the negative thread, respectively.

[0031] Further, see Figure 1 , 2 The width of the snap-fit ​​groove 3 is greater than the thickness of the tube segment, and a buffer pad 16 is provided inside the snap-fit ​​groove 3.

[0032] Preferably, the cushioning pad 16 is made of rubber.

[0033] In the above setup, after the two sets of tunnel segments are hoisted onto the trailer body with their arched ends facing each other, the snap-fit ​​grooves 3 on the snap-fit ​​sleeves 101 are used to snap the two sets of tunnel segments respectively. Since the connecting column 4 is fixedly connected to the locking plate 5 and rotatably connected to the snap-fit ​​sleeves 101, the snap-fit ​​sleeves 101 can rotate along the connecting column 4 during the connection process with the tunnel segments, thereby adjusting the opening orientation of the snap-fit ​​grooves 3 to facilitate snap-fit ​​with the tunnel segments. After the snap-fit ​​sleeves 101 are connected to the tunnel segments, the locking studs 201 are rotated, and under the action of the threads, the two sets of snap-fit ​​sleeves 101 move towards each other, thereby snapping the upper ends of the two sets of tunnel segments together. The snap-fit ​​sleeves 101 and locking studs 201 are arranged in two sets, respectively connected to both ends of the tunnel segments. The snap-fit ​​sleeves 101 and the tunnel segments are isolated by the buffer suspension to avoid the snap-fit ​​sleeves 101 directly acting on the tunnel segments and causing external damage to the tunnel segments.

[0034] Further, see Figure 4 The support member 6 includes a support plate 601 and a connecting rod 602 disposed on the support plate 601. The connecting rod 602 is disposed perpendicular to the support plate 601, and an adjusting sleeve 603 is provided at the end of the connecting rod 602 away from the support plate 601. The protective sleeve 9 is a rubber sleeve disposed on the support plate 601.

[0035] Preferably, the bearing plate 601 and the connecting rod 602 form a "T" shaped structure.

[0036] Preferably, the support plate 601 is provided with a second connecting ring 21.

[0037] Further, see Figure 4 The adjusting component 7 includes an adjusting screw 701 rotatably disposed within the adjusting sleeve 603, and the abutting component 8 includes two sets of abutting plates 801 spaced apart on the adjusting screw 701. One set of abutting plates 801 is connected to the adjusting screw 701 by a straight thread, and the other set of abutting plates 801 is connected to the adjusting screw by a reverse thread. One end of the limiting rod 10 is fixedly connected to the adjusting sleeve 603, and the other end is slidably connected to the abutting plate 801.

[0038] Preferably, the middle part of the adjusting screw 701 is provided with a smooth rod section 17, which is rotatably disposed in the adjusting sleeve 603, and the two ends of the smooth rod section 17 are respectively provided with limit rings 18.

[0039] Preferably, the smooth section 17 of the adjusting screw has external threads in opposite directions on both sides.

[0040] Preferably, the abutment plate 801 is provided with a sliding hole 19, and the limiting rod 10 is located in the sliding hole 19.

[0041] Further, see Figure 4 The clamping plate 801 has a triangular structure and the bottom plate of the clamping plate 801 is arc-shaped; the limiting rod 10 is set in parallel with the adjusting screw 701.

[0042] Preferably, the center of the clamping plate 801 is provided with a tightening screw hole 20, and the tightening screw 701 is threadedly connected to the tightening screw hole 20. The threads in the two sets of tightening screw holes 20 at the center of the clamping plates 801 are in opposite directions.

[0043] Preferably, the outer wall of the clamping plate 801 is covered with a rubber pad layer.

[0044] In the above configuration, the bearing plate 601 is placed on the middle of the upper end face of the two sets of pipe segments, and the connecting rod 602 is located between the two sets of pipe segments, so that the clamping plate 801 is located between the two sets of pipe segments. Rotating the adjusting screw 701 drives the two clamping plates 801 to move towards each other. The arc-shaped sides on the two clamping plates 801 abut against the outer wall of the arc arch of the pipe segment, thereby filling the gap between the two sets of pipe segments. The clamping sleeve 101 connects the two sets of pipe segments, so that the relative position between the two sets of pipe segments is fixed.

[0045] In this embodiment, the snap-fit ​​sleeve 101 is snapped onto the upper end face of the two sets of pipe segments, and the locking stud 201 drives the two sets of snap-fit ​​sleeves 101 to move towards each other to fix the two sets of pipe segments. The bearing plate 601 supports the two sets of abutment plates 801 between the two sets of pipe segments. When the tightening stud is rotated, the two sets of abutment plates 801 move towards each other to abut against the two sets of pipe segments, thereby fixing the relative position between the two sets of pipe segments. Finally, the connecting steel cable 11 is used to connect to the bearing plate 601 and the snap-fit ​​sleeve 101 respectively, and then the connecting steel cable 11 is connected to the trailer, thereby fixing the pipe segments on the trailer.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
