Description

Technical Field

[0001] This utility model relates to a construction platform, specifically a construction platform for mixed tower hoisting. Background Technology

[0002] A wind turbine generator is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] Wind turbine generator sets mainly consist of the main unit and a concrete tower. The concrete tower is a conical, hollow structure, constructed from multiple tower sections of varying diameters. During construction, the largest diameter section is typically placed at the bottom, and concrete adhesive is applied to its upper surface. Then, a crane lifts the second-largest diameter section and places it on top of the largest diameter section for fixation. This process is repeated until all sections are securely joined. To facilitate construction, a construction platform is usually installed in the hollow section of the tower to be worked on, allowing workers to perform their tasks. However, existing platforms are typically bulky frame structures. These need to be installed on the tower sections and dismantled after construction, a time-consuming and labor-intensive process that increases worker workload and reduces efficiency. Furthermore, the fixed dimensions of existing platforms prevent adjustments based on the tower's inner diameter, necessitating the use of platforms of various sizes, thus increasing construction costs. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a construction platform for mixed tower hoisting, thereby improving construction efficiency, reducing the labor intensity of construction workers, and lowering construction costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a construction platform for mixed tower hoisting includes an installation frame, two sliding arm mechanisms respectively slidably connected to the bottom of the installation frame, a counterweight water tank and a load-bearing basket respectively fixed to the two sliding arm mechanisms, a water inlet and outlet mechanism fixed to the bottom of the installation frame and connected to the counterweight water tank, a first drive mechanism fixed to the installation frame that enables the two sliding arm mechanisms to move closer or further apart along their length, an installation plate located directly above the installation frame, a second drive mechanism fixed between the installation plate and the installation frame that enables the installation frame to rotate, multiple lifting lugs fixed to the top of the installation plate, and a control mechanism fixed to the installation plate and electrically connected to the water inlet and outlet mechanism, wherein the control mechanism controls the water inlet and outlet mechanism to make the counterweight water tank fill or drain water so that the load-bearing basket and the counterweight water tank remain balanced after being loaded.

[0006] As a limitation of this utility model, the sliding arm mechanism includes a sliding rod and a rack fixed to the bottom of the sliding rod by two limiting plates.

[0007] As a further limitation of this utility model, the first drive mechanism includes a first drive motor fixed on the mounting bracket and a drive gear fixed on the power output end of the first drive motor. The drive gear is located between two racks and meshes with the two racks.

[0008] As another limitation of this utility model, the water inlet and outlet mechanism includes a water supply tank fixed at the bottom of the mounting frame and a bidirectional water pump connected to the water supply tank, wherein the bidirectional water pump is connected to the counterweight water tank.

[0009] As a further limitation of this utility model, the control mechanism includes an inclination sensor fixed on the mounting plate and a controller component fixed on the mounting plate. The controller component is electrically connected to the inclination sensor and to the bidirectional water pump.

[0010] As a further limitation of this utility model, the supporting basket is fixedly provided with a connecting ring for hooking on the construction safety belt.

[0011] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0012] (1) This utility model adopts a structure combining an installation frame, two sliding arm mechanisms, a counterweight water tank, a bearing basket, a water inlet and outlet mechanism, a first drive mechanism, an installation plate, a second drive mechanism, multiple lifting lugs and a control mechanism. The bearing basket can carry construction personnel and construction tools. The control mechanism controls the water inlet and outlet mechanism to make the counterweight water tank fill or return water so that the bearing basket and the counterweight water tank remain balanced after being loaded. When in use, the construction personnel stand on the bearing basket, and the crane suspends multiple lifting lugs and lifts this utility model to the tower section to be constructed. The construction personnel can then carry out the corresponding construction work. Compared with the existing construction platform, this utility model does not require installation and dismantling operations, which can reduce the labor intensity of construction personnel and improve construction efficiency. Furthermore, the first and second drive mechanisms work together to adjust the position of the load-bearing basket. Specifically, the first drive mechanism can adjust the distance between the load-bearing basket and the counterweight water tank, while the second drive mechanism can rotate the load-bearing basket in a plane. During use, the position of the load-bearing basket can be adjusted according to the different inner diameters of the tower to meet the construction needs. It can be used in the construction of tower sections with different diameters. This utility model has a wider range of applications, and in actual construction, there is no need to equip multiple construction platforms, which can effectively reduce construction costs.

[0013] (2) The present invention adopts a transmission structure in which rack and pinion and drive gear are combined. This transmission structure has high transmission accuracy, large load capacity and low operating noise. In actual use, the two sliding arm mechanisms can move more stably, which can effectively improve the stability and reliability of the present invention structure.

[0014] (3) This utility model is equipped with a water supply tank, a two-way water pump, an inclination sensor and a controller component. When the inclination sensor senses that the tilt angle of the mounting frame has changed, it can transmit the information to the controller component and control the two-way water pump to make the counterweight water tank enter or return water, thereby keeping the load-bearing basket and the counterweight water tank in balance. In actual use, this utility model can automatically adjust the weight of the counterweight water tank according to the different loads in the load-bearing basket, thereby keeping the load-bearing basket and the counterweight water tank in balance, which can effectively improve the practicality of this utility model.

[0015] (4) The present invention is provided with a connecting ring. When using it, construction personnel can hook the construction safety belt onto the connecting ring, which can effectively improve the safety of the present invention when using it.

[0016] In summary, this utility model features a simple structure, high safety, ease of use, and strong practicality. It requires no installation or dismantling; during use, a crane is used to suspend multiple lifting lugs and lift the utility model to the desired tower section, allowing construction workers to perform their tasks. This reduces labor intensity and improves construction efficiency. Furthermore, the position of the support basket can be adjusted to accommodate different tower diameters, making it suitable for construction of tower sections with varying diameters. This broadens its applicability, as it eliminates the need for multiple construction platforms, effectively reducing construction costs. This utility model is particularly suitable for use in mixed-tower construction. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] Example 1: A construction platform for mixed tower hoisting

[0023] like Figure 1 , Figure 2 As shown, this embodiment includes a mounting frame 1, two sliding arm mechanisms slidably connected to the bottom of the mounting frame 1, a counterweight water tank 5 and a carrying basket 6 respectively fixed on the two sliding arm mechanisms, a water inlet and outlet mechanism fixed on the bottom of the mounting frame 1 and connected to the counterweight water tank 5, a first drive mechanism fixed on the mounting frame 1 that enables the two sliding arm mechanisms to move closer or further apart along the length direction, a mounting plate 10 located directly above the mounting frame 1, a second drive mechanism fixed between the mounting plate 10 and the mounting frame 1 that enables the mounting frame 1 to rotate, a plurality of lifting lugs 11 fixed on the top of the mounting plate 10, and a control mechanism fixed on the mounting plate 10 and electrically connected to the water inlet and outlet mechanism. The counterweight water tank 5 is a rectangular box with a vent hole at the top.

[0024] The sliding arm mechanism includes a sliding rod 2 and a rack 4 fixed to the bottom of the sliding rod 2 by two limiting plates 3. The rack 4 is parallel to the sliding rod 2. Specifically, in this embodiment, the sliding rod 2 is a rectangular rod, and the limiting plates 3 are rectangular plates. Both limiting plates 3 are vertically fixed to the bottom of the sliding rod 2, and the sliding rod 2 is slidably connected to the bottom of the mounting frame 1.

[0025] The first drive mechanism includes a first drive motor 7 fixed on the mounting frame 1 and a drive gear 8 fixed on the power output end of the first drive motor 7. The drive gear 8 is located between two racks 4 and meshes with the two racks 4. The first drive motor 7 is an existing structure that can rotate in both forward and reverse directions. The second drive mechanism is a second drive motor 9. The second drive motor 9 is an existing structure that can rotate in both forward and reverse directions.

[0026] The mounting plate 10 is a rectangular plate, and a lifting lug 11 is fixed at each of the four corners of the mounting plate 10.

[0027] The water inlet and outlet mechanism includes a water supply tank 12 fixed at the bottom of the mounting frame 1 and a bidirectional water pump 13 connected to the water supply tank 12 via a water pipe. The bidirectional water pump 13 is connected to the counterweight water tank 5 via a water pipe.

[0028] The control mechanism controls the water inlet and outlet mechanisms to allow water to enter or exit the counterweight water tank 5, maintaining the balance between the loaded support basket 6 and the counterweight water tank 5. It is necessary to ensure that the tilt angle between the support basket 6 and the counterweight water tank 5 is within a safe range when they are in a balanced state, meaning that construction personnel standing inside the support basket 6 will not fall out and can safely carry out construction. Specifically, in this embodiment, the control mechanism includes a tilt sensor 14 fixed to the mounting plate 10 and a controller component fixed to the mounting plate 10. The controller component is electrically connected to the tilt sensor 14 and to the bidirectional water pump 13, and the controller component is a PLC controller. It should be noted that the control mechanism in this embodiment has two control modes: automatic control mode and manual control mode. When the automatic control mode is activated, the tilt sensor 14 can detect the tilt angle of this embodiment. The controller component has a preset tilt angle threshold for activating and pausing the bidirectional water pump 13. When the tilt angle received by the controller component exceeds the preset tilt angle threshold, the controller component can control the bidirectional water pump 13 to operate, causing the counterweight water tank 5 to fill or drain water, thus limiting the tilt angle between the loaded support basket 6 and the counterweight water tank 5 to a safe range. When the tilt angle received by the controller component is less than the tilt angle threshold, the controller component can control the bidirectional water pump 13 to stop operating, at which time the water in the counterweight water tank 5 remains unchanged. When the manual control mode is activated, the controller component cannot automatically adjust the water inlet or outlet of the counterweight water tank 5; the water inlet or outlet of the counterweight water tank 5 can only be adjusted manually.

[0029] To improve the safety of this embodiment, a connecting ring 15 for hooking on the construction safety belt is fixed on the supporting basket 6.

[0030] When using this embodiment, construction workers enter the load-bearing basket 6 and place construction supplies into it. They then hook their safety belts onto the connecting ring 15 and control the water inlet and outlet mechanisms to allow the counterweight water tank 5 to fill or empty until the load-bearing basket 6 and the counterweight water tank 5 are level or the angle between them is within a safe range. After this, the water inlet and outlet of the counterweight water tank 5 are stopped. Then, the four lifting lugs 11 are suspended by a crane, and the embodiment is lifted to the location where construction is required. At this point, construction workers can stand inside the load-bearing basket 6 to carry out construction work. When the position of the carrying basket 6 needs to be adjusted, the first drive mechanism is rotated forward or backward. The forward or backward rotation of the first drive mechanism can drive the drive gear 8 to rotate forward or backward. The forward or backward rotation of the drive gear 8 can cause the two racks 4 to move closer or further apart along the length of the racks until the carrying basket 6 moves to the required position. Then the first drive mechanism stops working and the second drive mechanism rotates. The rotation of the second drive mechanism can drive the mounting frame 1 to rotate. The mounting frame 1 can drive the carrying basket 6 to rotate until the carrying basket 6 moves to the required position. Then the second drive mechanism stops working.

[0031] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. 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.
