Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a gantry-type self-propelled precast wind power tower ring slab pouring machine. Background Technology

[0002] Concrete pouring and vibration are key steps in the production of precast wind turbine towers. The methods and equipment used for pouring and vibration have a significant impact on the overall production layout, labor costs, production efficiency, and quality assurance. Currently, the industry mainly adopts a traditional separate operation method for the concrete pouring and vibration processes of precast wind turbine tower rings: in the concrete pouring stage, pump trucks are generally relied upon to complete the concrete delivery and placement; in the concrete vibration stage, manual operation of immersion vibrators is mainly used to achieve concrete compaction.

[0003] However, the aforementioned traditional operating methods have obvious technical drawbacks:

[0004] Regarding concrete pouring, firstly, the purchase cost and daily maintenance expenses of pump trucks are high, and professional operators are required, which significantly increases the cost of using machinery in the concrete pouring process; secondly, during operation, the movement, outrigger extension, and boom rotation of pump trucks require a large amount of space, which greatly increases the floor space occupied by the production area and is not conducive to a compact factory layout; thirdly, the pouring coverage of pump trucks is limited. Each wind turbine tower has dozens of molds, and frequent changes of work positions are required to complete the pouring operation. Each work position change requires the pump truck to move, which takes a long time and seriously restricts the improvement of production efficiency.

[0005] Regarding concrete vibration, firstly, the manual operation of immersion vibrators is labor-intensive, requiring a large number of workers and resulting in high labor costs; secondly, operators need to frequently pull out and remove the vibrator and move the vibration point, making the operation process cumbersome and the vibration efficiency low; thirdly, the vibration quality is highly dependent on the operator's experience and sense of responsibility, and problems such as missed vibration, over-vibration, or under-vibration are easily caused by human operation deviations, which directly affect the compactness and structural strength of the concrete, leading to unstable product quality.

[0006] Therefore, in order to realize the mechanization and automation of the casting and vibration process of wind turbine hybrid tower rings, improve production efficiency, reduce production costs, and ensure product quality, a gantry-type self-propelled precast wind turbine hybrid tower ring casting and vibration integrated machine is proposed. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gantry-type self-propelled precast wind power tower ring slab casting and tamping integrated machine.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a gantry-type self-propelled precast wind turbine tower ring slab casting and tamping integrated machine, including a gantry,

[0009] The upper part of the gantry is provided with a vibration assembly, which includes a rotating platform, a vibrator, and a vibrating rod. The rotating platform is connected to the upper platform of the gantry through a rotating mechanism. The rotating platform is provided with multiple laterally movable extension arms. Laterally movable vibrators are installed on the extension arms. The vibrating rod is connected to the output end of the vibrator through a vibrator hose.

[0010] The gantry is also equipped with a pump pipe assembly;

[0011] The bottom of the gantry is equipped with four sets of omnidirectional casters for the movement of the integrated pouring and tamping machine.

[0012] As a further description of the above technical solution:

[0013] A vibrator hose guide wheel is fixedly installed on the extension arm, and the vibrator hose passes through the vibrator hose guide wheel so that one end of the vibrator rod is perpendicular to the bottom surface.

[0014] As a further description of the above technical solution:

[0015] The pump pipe assembly includes a fixed pump pipe, a first-stage rotary pump pipe, a second-stage rotary pump pipe, and a concrete discharge port perpendicular to the ground.

[0016] The first-stage rotary pump tube is connected to the fixed pump tube, the first-stage rotary pump tube is connected to the second-stage rotary pump tube, and the second-stage rotary pump tube is connected to the discharge port through a pump tube rotation mechanism.

[0017] As a further description of the above technical solution:

[0018] A ground pump placement platform is installed on the lower part of one side of the gantry. The ground pump is installed on the ground pump placement platform, and a fixed pump pipe is installed on the gantry. One end of the fixed pump pipe is connected to the output end of the ground pump, and the other end of the fixed pump pipe is connected to a first-order rotating pump pipe through a pump pipe rotation mechanism.

[0019] As a further description of the above technical solution:

[0020] An infrared positioning device is installed on the gantry or rotating platform. This infrared positioning device is used to accurately locate the arc center of the arc mold.

[0021] As a further description of the above technical solution:

[0022] The rotating mechanism can drive the rotating platform to rotate 360° in place. When the rotating platform rotates, it can drive the first-order rotating pump pipe, the second-order rotating pump pipe and the extension arm to make a circular motion simultaneously.

[0023] As a further description of the above technical solution:

[0024] The gantry, rotating platform, extension arm, and pump pipe assembly adopt a modular structure design, and the modules are fixed together by detachable connectors.

[0025] As a further description of the above technical solution:

[0026] Both the lateral travel of the extension arm and the lateral travel of the vibrator can be adjusted independently, allowing the vibration operation to be synchronized with the concrete pouring operation.

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, by integrating the gantry, vibrating assembly, pump pipe assembly, and universal wheels into one unit, a gantry-type self-propelled precast wind turbine hybrid tower ring slab casting and tamping machine is formed. This machine can directly realize the mechanization and automation of the wind turbine hybrid tower ring slab casting and vibrating processes. Unlike existing technologies, it does not rely on pump trucks and manual operation of insertion vibrators, effectively reducing the connection time between processes and equipment conversion costs. This not only significantly improves the overall production efficiency but also reduces cost fluctuations caused by manual intervention through standardized mechanical operation processes. At the same time, it avoids quality deviations that may occur during manual operation, effectively ensuring the product quality stability of the precast wind turbine hybrid tower ring slabs.

[0029] 2. In this utility model, automatic material distribution is achieved by using a fixed pump pipe, a first-stage rotating pump pipe, a second-stage rotating pump pipe, and a discharge port in conjunction with a ground pump in a pump pipe assembly. This completely replaces the high-cost concrete pump truck pouring operation in the prior art, saving the high purchase cost, daily maintenance cost, and dedicated personnel operation cost of the pump truck, and significantly reducing the cost of using machinery. At the same time, automatic vibration is achieved by using a laterally movable extension arm on a rotating platform in conjunction with a vibrator, replacing the traditional manual insertion vibrator mode. This not only reduces the number of operators required and lowers labor costs, but also reduces the labor intensity of the operators. Furthermore, the automated mechanical vibration can operate strictly according to the preset vibration frequency, depth, and range, effectively avoiding quality problems such as missed vibration, under-vibration, and over-vibration caused by human factors such as fatigue and experience differences in manual operation, further ensuring the density and overall strength of the concrete structure.

[0030] 3. The four sets of omnidirectional casters installed at the bottom of the gantry give the equipment flexible self-propelled functionality, allowing it to be easily moved to different positions for the mixing tower ring mold without relying on external traction equipment. At the same time, the rotating mechanism can drive the rotating platform to rotate 360° in place, causing the pump pipe assembly and vibrating assembly to move in a circular motion synchronously. The ring mold can be completed in its entirety without frequent adjustments to the overall position of the equipment. The workstation conversion is flexible and efficient. Compared with the existing technology where pump trucks require a large space for walking, outriggers and boom rotation, the working area required by this equipment is greatly reduced, reducing the area occupied in the production area and making it more conducive to the optimization of the factory production layout.

[0031] 4. The infrared positioning device installed on the gantry or rotating platform can accurately position the center of the circular (arc) mold, ensuring that when the rotating platform drives the discharge port and vibrator to rotate 360°, it is always accurately aligned with the mold cavity area, avoiding problems such as misaligned pouring or inadequate vibration caused by positioning deviation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figures 1-2 The present invention provides an embodiment of a gantry-type self-propelled precast wind turbine tower ring slab casting and tamping machine, comprising a gantry 1, characterized in that:

[0040] The upper part of the gantry 1 is equipped with a vibration assembly, which includes a rotating platform 3, a vibrator 13, and a vibrating rod 16. The rotating platform 3 is connected to the upper platform of the gantry 1 through a rotating mechanism 4. The rotating platform 3 is equipped with multiple laterally movable extension arms 12, and the laterally movable vibrators 13 are installed on the extension arms 12. The vibrating rod 16 is connected to the output end of the vibrator 13 through a vibrator hose 14. The gantry 1 is also equipped with a pump pipe assembly. The bottom of the gantry 1 is equipped with four sets of omnidirectional wheels 2 for the movement of the integrated pouring and tamping machine.

[0041] Thus, by integrating the gantry 1, vibratory assembly, pump pipe assembly, and omnidirectional wheels 2 into one unit, a gantry 1-type self-propelled precast wind turbine hybrid tower ring slab casting and tamping machine is formed. This machine can directly realize the mechanization and automation of the wind turbine hybrid tower ring slab casting and vibratory processes. Unlike existing technologies, it does not rely on pump trucks and manual operation of the insertion vibrator 13, effectively reducing the connection time between processes and the equipment conversion cost. This not only greatly improves the overall production efficiency, but also reduces the cost fluctuations caused by manual intervention through standardized mechanical operation processes. At the same time, it avoids the quality deviations that may occur during manual operation, and effectively ensures the product quality stability of the precast wind turbine hybrid tower ring slabs.

[0042] The gantry-type self-propelled precast wind turbine tower ring slab casting and compaction machine in this application embodiment can be applied to the wind turbine tower ring slab casting and vibration processes, specifically, but not limited to: precast concrete wind turbine towers, precast concrete culverts, and other precast concrete components.

[0043] See Figures 1-2 The extension arm 12 is fixedly installed with a guide wheel for the vibrator hose 14. The vibrator hose 14 passes through the guide wheel so that one end of the vibrator rod 16 is perpendicular to the bottom surface.

[0044] The pump pipe assembly includes a fixed pump pipe 5, a first-stage rotary pump pipe 7, a second-stage rotary pump pipe 8, and a concrete discharge port 9 perpendicular to the ground.

[0045] The first-stage rotary pump tube 7 is connected to the fixed pump tube 5, the first-stage rotary pump tube 7 is connected to the second-stage rotary pump tube 8, and the second-stage rotary pump tube 8 is connected to the discharge port 9 through the pump tube rotation mechanism 6.

[0046] A ground pump placement platform 10 is installed on the lower part of one side of the gantry 1. A ground pump 11 is installed on the ground pump placement platform 10. A fixed pump pipe 5 is installed on the gantry 1. One end of the fixed pump pipe 5 is connected to the output end of the ground pump 11. The other end of the fixed pump pipe 5 is connected to a first-order rotating pump pipe 7 through a pump pipe rotation mechanism 6.

[0047] An infrared positioning device is installed on the gantry 1 or the rotating platform 3. This infrared positioning device is used to accurately position the arc center of the arc mold.

[0048] The rotating mechanism 4 can drive the rotating platform 3 to rotate 360° in place. When the rotating platform 3 rotates, it can drive the first-order rotating pump pipe 7, the second-order rotating pump pipe 8 and the extension arm 12 to make a circular motion simultaneously.

[0049] The gantry 1, rotating platform 3, extension arm 12 and pump pipe assembly adopt a modular structure design, and each module is fixed by a detachable connector.

[0050] The lateral travel of the boom 12 and the lateral travel of the vibrator 13 can be adjusted independently, and the vibration operation is synchronized with the concrete pouring operation.

[0051] To better understand the gantry-type self-propelled precast wind power tower ring slab casting and tamping machine of this application embodiment, refer to... Figures 1-4 The following is a specific embodiment:

[0052] First, the operator controls the device to move the four sets of omnidirectional wheels 2 at the bottom of the gantry 1 to transport the integrated pouring and tamping machine to the placement position of the precast wind power tower ring plate mold 17. At this time, the device accurately positions the center of the circular (arc) mold through the infrared positioning device installed on the gantry 1 or the rotating platform 3, ensuring that the subsequent working parts can be aligned with the core working area of ​​the mold, and completing the initial positioning preparation of the equipment.

[0053] After positioning is completed, the operator adjusts the pump pipe assembly: through the pump pipe rotation mechanism, the angles of the first-stage rotating pump pipe 7 and the second-stage rotating pump pipe 8 are adjusted respectively, so that the concrete discharge port 9, which is perpendicular to the ground, is precisely aligned with the mold cavity 18; at the same time, the multiple horizontally movable extension arms 12 on the rotating platform 3 are adjusted, which drives the concrete vibrator 13 on the extension arms 12 to move horizontally in sync, so that the vibrator 13, connected by the rubber hose, the vibrator rod 16 (guided by the guide wheel to remain perpendicular to the ground) is also aligned with the corresponding vibration area of ​​the mold cavity 18, thus completing the alignment of the pouring and vibration operation.

[0054] The operation process is then initiated: First, the ground pump 11 installed on the lower platform on one side of the gantry 1 is turned on. The ground pump 11 delivers concrete to the fixed pump pipe 5 on the gantry 1. The concrete flows through the fixed pump pipe 5 in sequence through the first-stage rotary pump pipe 7 and the second-stage rotary pump pipe 8, and finally is injected into the mold cavity 18 from the discharge port 9. At the same time, the rotating mechanism 4 drives the rotating platform 3 to rotate 360° in place, which drives the first-stage rotary pump pipe 7, the second-stage rotary pump pipe 8 and the discharge port 9 to make a circular motion, so that the concrete is evenly poured into the entire circle of the mold cavity 18.

[0055] When a certain amount of concrete (meeting the requirements of layered pouring process) is poured into the mold cavity 18, the vibration operation is started simultaneously: the extension arm 12 moves the vibrator 13 forward, so that the vibrator rod 16 is inserted downward into the concrete for vibration; after the vibration is completed, the vibrator 13 moves backward and the vibrator rod 16 is pulled out of the concrete; the rotating platform 3 continues to rotate to the next unvibrated area, repeating the above actions of "extension arm 12 moves forward - vibrator rod 16 is inserted for vibration - vibrator 13 moves backward - rotating platform 3 rotates", so as to achieve the coordinated cooperation of layered concrete pouring and layered vibration.

[0056] After the entire ring of concrete has been poured and vibrated, the second-stage rotating pump pipe 8 is rotated via the pump pipe rotation mechanism to adjust the discharge port 9 to a position slightly above horizontal to prevent residual concrete from dripping and contaminating the mold or site. If the next ring needs to be poured, simply control the omnidirectional wheels 2 to move the equipment again and repeat the above "positioning-alignment-pouring and vibration-resetting" process. When it is necessary to move to another production site, the modular design of the device can be used to quickly disassemble the gantry 1, rotating platform 3, extension arm 12, pump pipe assembly, etc., for easy transportation. Upon arrival at the new site, they can be quickly reassembled to restore operational capacity.

[0057] Finally, it should be noted that the above description is only 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing 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.
