Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind power concrete tower engineering, in particular to a rotating type construction platform for the top surface of a tower pipe piece and a construction method thereof. BACKGROUND

[0002] The application of a segmented precast assembled concrete tower in the field of wind power generation is becoming increasingly common. The tower pipe pieces are assembled into sections on a ground assembly platform and then hoisted by a crane to the wind turbine foundation, where they are stacked one section at a time to complete the tower assembly. In this process, a large amount of structural adhesive material is used. During the assembly into sections, structural adhesive is applied to the side surfaces of the pipe pieces to bond and fix them. This process is completed manually on the ground assembly platform, and the construction quality and safety risks are relatively controllable. However, during the stacking process, structural adhesive is also applied to the top of the pipe pieces to achieve connection and fixation with the next section. This process requires multiple workers to complete the mixing of structural adhesive on a dedicated hoisting platform, and then apply it to the top surface of the pipe pieces. The quality of structural adhesive application varies from person to person and is heavily dependent on the workers' techniques, which is not conducive to construction quality control.

[0003] Currently, there is no completely applicable facility and equipment for the above-mentioned environment and working conditions in the prior art.

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0039] like Figures 1-12 As shown, a rotating construction platform for the top surface of a hybrid tower segment includes a wall-mounted module A and a rotating platform B. The wall-mounted module A and the rotating platform B are connected by a guide rail 1 to form a whole. A fence C is installed inside or outside the segment D. The rotating platform B includes a rotating base 8 connected to the fence C, allowing the rotating platform B to form an independent working area within the fence C. An equipment platform 7 is installed on the rotating platform B. The wall-mounted module A has an equipment output end located above the top surface of the segment D, and the equipment platform 7 has an equipment power end connected to the equipment output end. Caster sets 6 are installed at both ends of the wall-mounted module A, acting in conjunction with the top and sides of the segment D. The caster sets 6 on both sides are connected by an elastic component 5006. The equipment platform 7 has an upright 7004 hinged to the guide rail 1, and also has an angle adjustment structure connected to the guide rail 1.

[0040] In this embodiment, the construction platform can be used to mount various types of instruments, equipment, and tools, and achieve diverse functional requirements through different combinations. In particular, in this embodiment, grinding, purging, sandblasting, and gluing can be completed simultaneously in one process, which solves the problem of inconsistent and uncontrollable construction quality caused by excessive reliance on manual labor. This ensures that the construction operation on the top surface of the mixed tower segment D is controllable and consistent, while improving the level of automation in construction, so that construction personnel no longer need to pay attention to the construction process and results, but only need to operate the construction platform.

[0041] In this embodiment, the guide rail 1 is made of I-beams, which are selected according to the length and load. It is preferred to use 10# I-beams. The guide rail can be adapted to different diameter mixed tower segments D according to the length and load, so as to help complete the sandblasting and gluing of the corresponding diameter segments D, thereby making the installation effect of the next segment D better.

[0042] Example 1:

[0043] like Figure 1 As shown, the fence C is set inside the segment D so that the rotating platform B is located inside the segment D and drives the wall-mounted module A to move on the top surface of the segment D.

[0044] like Figures 1-3 As shown, specifically, the output end of the wall-mounted module A includes zoned nozzles A1 and spray heads A2. The power end of the equipment on the equipment platform 7 includes a sandblasting machine B1 and a structural adhesive pressing machine B2. The sandblasting machine B1 is connected to the nozzle A1 via an air pipe, and the structural adhesive pressing machine B2 is connected to the spray head A2 via a material pipe. By placing the power components of various construction equipment on the equipment platform 7 and only connecting the output end to the wall-mounted module A for construction, the overall design of the construction platform becomes simple and clear. Furthermore, it allows for easy addition or removal of commercially available construction equipment as needed, without requiring specialized development to expand the platform's functionality.

[0045] like Figures 4-9 As shown, specifically, the wall-mounted module A includes a trolley 2, a turntable bearing 3, a seated universal joint 4, and a linear guide rail platform 5. The trolley 2 is slidably connected to the guide rail 1. The turntable bearing 3 is connected between the trolley 2 and the seated universal joint 4. The linear guide rail platform 5 is connected to the bottom of the seated universal joint 4. The caster assembly 6 is slidably connected to the bottom of the linear guide rail platform 5.

[0046] like Figures 4-5 As shown, the trolley 2 includes a U-shaped frame 2001. Inside the U-shaped frame 2001, frustum-shaped rollers 2002 and cylindrical rollers 2003 are arranged in upper and lower layers. The upper frustum-shaped rollers 2002 and the lower cylindrical rollers 2003 work together with the guide rail 1 to make the trolley 2 move on the guide rail 1.

[0047] In this embodiment, the frustum-shaped roller 2002 can be a frustum-shaped roller bearing, and the cylindrical roller 2003 can be a cylindrical roller bearing. Four circular holes are symmetrically drilled on each of the two vertical plates on both sides of the U-shaped frame 2001, and eight fixing bolt holes are drilled on the bottom plate for connection with the turntable bearing 3. The four circular holes on the upper layer are used to install frustum-shaped roller bearings, and the four circular holes on the lower layer are used to install cylindrical roller bearings. Both the frustum-shaped roller bearings and the cylindrical roller bearings are fixed by bolts.

[0048] Therefore, the gap between the upper circular cone roller 2002 and the lower cylindrical roller 2003 just matches the lower part of the guide rail 1 and makes the guide rail 1 pass through; so that the wall-riding module A can be stably fixed on the I-beam and can freely slide on the I-beam.

[0049] As Figures 6-8 shown, wherein the turntable bearing 3 comprises a turntable outer wheel 3001 and a turntable inner wheel 3002, the turntable inner wheel 3002 is fixed by bolt connection with the U-shaped frame 2001 bottom plate of the trolley 2; the seat universal connecting rod 4 comprises a circular bearing platform 4001, a connecting rod 4002 and a universal connecting seat 4003 connected in sequence from top to bottom, the universal connecting seat 4003 adopts a square seat with a spherical bearing inside, one end of the connecting rod 4002 is connected with the circular bearing platform 4001, and the other end is inserted into the universal connecting seat 4003 and fixed, the circular bearing platform 4001 is fixed by bolt connection with the turntable outer wheel 3001; the linear guide bearing platform 5 comprises a square bearing platform 5003 connected with the universal connecting seat 4003, the square bearing platform 5003 is provided with linear guides 5001 at both ends, the square bearing platform 5003 is located in the middle of the linear guides 5001, which divides the linear guides 5001 into two sections, the linear guides 5001 are provided with sliders 5002 connected with the top of the caster group 6, and the elastic components 5006 are arranged between the sliders 5002 on both sides and connected with the end portions of the sliders 5002. The elastic components 5006 are preferably springs.

[0050] Therefore, the wall-riding module A can realize 360-degree rotation in the axial direction and also has a bending redundancy of 15 to 15 degrees.

[0051] As Figure 8 shown, wherein the square bearing platform 5003 is provided with a movable connecting rod 5004 extending at the side end, the square bearing platform 5003 is provided with an ear to connect with the movable connecting rod 5004, and the end of the movable connecting rod 5004 away from the ear is provided with a fixed rod 5005 connected with the output end of the equipment. Moreover, the movable connecting rod can be a telescopic rod, which can be adjusted in length as needed.

[0052] Based on the above, the fixed rod 5005 is mainly used for fixing the output end of the construction equipment, such as a spray head, a nozzle, a polishing head, etc. It can be understood that the two fixed rods 5005 can fix the same output end or different output ends, so that the wall-riding module A has the function of a platform, and can mount the equipment output end on the fixed rod 5005 as needed without changing the structural design, so as to realize different functions and have good expansibility.

[0053] As Figure 9As shown, the caster assembly 6 includes a reinforced right-angle brace 6001, a top caster 6002, and a side caster 6003. The top caster 6002 is installed on the underside of the top plate of the reinforced right-angle brace 6001, and the side caster 6003 is installed on the inside side plate of the reinforced right-angle brace 6001, both fixed by bolts. The upper part of the top plate of the reinforced right-angle brace 6001 is fixed to the slider 5002 by bolts, and the side plates of the two caster assemblies 6 are arranged opposite each other with the mixing tower segments facing outwards.

[0054] In this embodiment, the top caster 6002 and the side caster 6003 are recommended to be swivel casters, and the wheel width, wheel configuration, etc. can be selected as needed.

[0055] Therefore, under the action of the elastic component 5006, the caster assembly 6 always fits tightly against the top and side surfaces of the tube segment D, ensuring that the linear guide rail 5001 of the linear guide rail support 5 is always on the diameter of the tube segment ring and does not tilt. Furthermore, the above technical solution can also be applied to tube segments of different thicknesses.

[0056] like Figure 10 As shown, specifically, the equipment platform 7 includes a chassis 7002, with a vertical pole 7004 erected on the chassis 7002. The end of the vertical pole 7004 is provided with a movable hinge 7003 connected to the bottom of the guide rail 1. The angle adjustment structure includes a winch 7001 installed on the upper surface of the chassis 7002. The winch 7001 is preferably a small winch, provided that the power is sufficient. The bottom of the guide rail 1 is provided with a lifting lug 7007, which is spaced from the movable hinge 7003. The wire rope 7006 of the winch 7001 passes through the lifting lug 7007 and is connected.

[0057] Therefore, the angle of guide rail 1 can be easily adjusted, and when the next tower section needs to be installed, guide rail 1 can be erected without hindering construction.

[0058] Two diagonal braces 7005 are provided, positioned opposite each other on the upright 7004. One end of each diagonal brace 7005 is connected to the upper part of the upright 7004, and the other end is connected to the edge of the circular base 7002, forming a triangular support between the diagonal braces 7005 and the upright 7004. The small winch 7001 is preferably placed inside the triangular support and fixedly connected to the circular base 7002.

[0059] like Figure 11As shown, in particular, the rotating base 8 comprises a support frame 8004, a slewing bearing 8001 is arranged above the support frame 8004, an inner ring disc 8005 connected with the support frame 8004 is arranged inside the slewing bearing 8001, the slewing bearing 8001 comprises an inner ring and an outer ring, the outer ring is fixed by bolt connection with the base 7002 of the equipment platform 7, and the outer ring is circumferentially provided with external teeth, and the inner ring is fixed by bolt connection with the inner ring disc 8005; a speed reducer 8003 is arranged at the bottom of the inner ring disc 8005, the speed reducer 8003 is a right-angle speed reducer, the output shaft of the speed reducer 8003 is parallel to the axial direction of the outer ring of the slewing bearing 8001 through a mounting frame, and a matching gear 8002 is mounted on the output shaft of the speed reducer 8003, the matching gear 8002 is engaged with the external teeth of the outer ring of the slewing bearing 8001.

[0060] In this embodiment, the support frame 8004 is a cross-shaped channel steel which is welded by channel steels of the same type.

[0061] Embodiment 2:

[0062] As Figure 12 shown, different from embodiment 1, this embodiment is applicable to the case that the fence C is arranged outside the segment D (the fence C is not shown in the figure), or a support member (not shown in the figure) is arranged at the bottom of the rotating platform B outside the segment D to provide support, so that the rotating platform B drives the riding wall module A to move on the top surface of the segment D outside the segment D. It should be noted that the rotating platform B is placed outside the circular ring of the segment D, and a longer guide rail is used. In construction, instead of rotating 360 degrees around the rotating platform B, the rotating platform B is rotated to one side until the guide rail 1 is close to tangent to the circular ring of the segment D, then the rotating direction is changed, until the guide rail 1 is tangent to the other side of the circular ring of the segment D, then the rotating direction is changed again, and so on until the whole ring construction operation is completed.

[0063] Please refer to Figures 1-12 , when the rotating construction platform is used to construct the top surface of the segment D, the specific steps are as follows:

[0064] S1: Construction equipment layout and pipeline connection: the sand blasting machine B1 and the structural adhesive pressure machine B2 are arranged at appropriate positions on the equipment platform 7 of the rotating platform B, the air pipe of the sand blasting machine B1 is connected to the sand blasting nozzle A1 of the fixed rod 5005 of the riding wall module A, and the material pipe of the pressure machine is connected to the nozzle A2 of the other fixed rod 5005 of the riding wall module A;

[0065] S2: Adjust the steel wire rope 7006 of the small hoist 7001 so that the guide rail 1 is at an appropriate angle;

[0066] S3: Move the mobile riding module A to the top surface of the segment D, manually pull open the two groups of wheels 6 to clamp the segment, and make the top wheels 6002 and the side wheels 6002 adhere to the top surface and the side surface of the segment D respectively; during the process, the angle of the guide rail 1 is continuously adjusted to make the riding module A in a slightly compressed or slightly tensioned state;

[0067] S4: Adjust the distance and angle between the nozzle A1, the spray head A2 and the top surface of the segment D;

[0068] S5: Start the rotating platform B to rotate slowly, start the construction equipment sand blasting machine B1 and the structural adhesive pressure machine B2 to work, and adjust the rotating speed of the rotating platform B to match the operating speed of the construction equipment sand blasting machine B1 and the structural adhesive pressure machine B2; it should be noted that the rotating direction of the rotating platform B at this time should be in front of the riding direction of the nozzle A1, and the spray head A2 should be behind the riding direction of the riding module A;

[0069] S6: After the construction is completed, stop the construction equipment sand blasting machine B1 and the structural adhesive pressure machine B2, stop the rotating platform B, tighten the steel wire rope 7006 of the winch 7001, and make the I-shaped steel 1 stand upright, so as to facilitate the installation of the next segment D, and thus complete the whole installation of the tower drum.

[0070] The above embodiment is only one of the preferred technical solutions of the present application, and those skilled in the art should understand that the technical solutions or parameters in the embodiment can be modified or replaced without departing from the principles and essence of the present application, and all should be covered within the protection scope of the present application.
