Description

Technical Field

[0001] This utility model belongs to the field of wind power construction, specifically an adaptive dynamic support and balancing device for a hybrid tower construction platform. Background Technology

[0002] The concrete tower construction platform is a core high-altitude work equipment in the construction and maintenance of concrete towers (such as wind turbine towers), mainly used to support construction personnel, building materials, and installation equipment. Its structure is as follows: Figure 1 As shown, the platform includes a bottom load-bearing beam 21 and a circumferential outer guardrail 22. The platform is typically suspended and fixed to the concrete tower wall 1 by multiple circumferentially distributed chains 3, relying on the coordinated force of the chains 3 to maintain the horizontal balance of the concrete tower construction platform 2.

[0003] However, the method of suspending and fixing with multiple chains 3 has the potential for chain 3 breakage in practical applications. The reasons for chain 3 breakage are as follows: First, construction materials or heavy equipment are stacked asymmetrically on the platform, causing local chains 3 to bear eccentric tensile forces far exceeding the design threshold; Second, during dynamic construction, external impacts or platform shaking cause a sudden increase in stress on the chain 3; Third, the strength of the chain 3 deteriorates due to fatigue damage or corrosion after long-term use.

[0004] When any chain 3 breaks due to abnormal load, the hybrid tower construction platform 2 will instantly lose the symmetrical lifting point constraint, and then tilt or even overturn due to force imbalance, seriously threatening the life safety of the workers. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide an adaptive dynamic support and balancing device for a hybrid tower construction platform, so as to support the hybrid tower construction platform when the chain breaks and ensure the balance of the hybrid tower construction platform.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adaptive dynamic support and balancing device for a hybrid tower construction platform includes a pneumatic catapult, an infrared sensor, a control switch, a control system, and cables;

[0008] The pneumatic catapult includes a launch tube, a launch rod nested inside the launch tube, and a pneumatic drive mechanism. The output end of the pneumatic drive mechanism is connected to the launch rod. The launch direction of the launch rod is along the radial direction of the mixed tower construction platform. The end of the launch rod away from the launch tube is set as a pointed structure.

[0009] One end of the cable is fixedly connected to the launch tube, and the other end is fixedly connected to the launch rod. After the launch rod is fired, the cable is in a taut state.

[0010] Infrared sensors are fixed on the outer wall of the transmitter tube to monitor the balance of the hybrid tower construction platform in real time.

[0011] The control system, pneumatic drive mechanism, and infrared sensor are all electrically connected to the control switch; the pneumatic drive mechanism and infrared sensor are all electrically connected to the control system.

[0012] As a limitation of this utility model: an anchoring unit is provided at the end of the launching rod away from the launching tube, and the anchoring unit has a pointed structure.

[0013] As a further limitation of this utility model: on the vertical projection plane, the anchoring unit is arrow-shaped, and the apex of the arrow shape is located at the end away from the launching tube.

[0014] As a further limitation of this utility model: both the launching rod and the anchoring unit are made of alloy steel.

[0015] As another limitation of this utility model: a winding roller is rotatably sleeved on the launching tube, the rotation axis of the winding roller is the same as the central axis of the launching tube, one end of the cable is fixed and wound on the winding roller, and the end of the cable away from the winding roller is fixedly connected to the launching rod.

[0016] As a further limitation of this utility model: an ear plate is fixedly provided on the launching rod, and the end of the cable away from the winding roller is fixedly connected to the ear plate.

[0017] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0018] This invention includes a pneumatic catapult, an infrared sensor, a control switch, a control system, and a cable. In use, the invention is installed at the bottom of a mixed-tower construction platform. The end of the launch rod in the pneumatic catapult faces the tower wall. Under the action of the pneumatic drive mechanism, the launch rod, carrying one end of the cable, is launched from the launch tube and eventually enters and anchors inside the tower wall. After the launch rod enters the tower wall, the cable is in a taut state, used to support the mixed-tower construction platform and prevent the platform from tilting or even overturning due to stress imbalance in the event of chain breakage.

[0019] The infrared sensor, control switch, and control system in this invention are used to automatically monitor and control the balance of the hybrid tower construction platform. During implementation, after the control switch is turned on, the infrared sensor and control system are operational. The infrared sensor sends a signal indicating that the hybrid tower construction platform is in a balanced state to the control system. When a chain breaks, the hybrid tower construction platform tilts. The infrared sensor immediately generates a tilt signal and sends it to the control system. The control system then activates the pneumatic drive mechanism, causing the launch rod to be launched from the launch tube, embedded in the tower wall, and anchored. At this point, the cable is taut, supporting the hybrid tower construction platform and preventing it from tilting, thus maintaining its balance. This invention provides adaptive dynamic support for the hybrid tower construction platform, ensuring the safety of the workers.

[0020] In summary, this invention enables adaptive dynamic support for hybrid tower construction platforms, ensuring the balance of the platforms and the safety of workers. This invention is applicable to the wind power construction industry and is used to provide adaptive dynamic support for hybrid tower construction platforms in the event of chain breakage.

Detailed Implementation

[0027] 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 illustration and explanation only and do not constitute a limitation thereof.

[0028] The directional terms or positional relationships such as "left" and "right" used in the embodiments are based on the drawings in this utility model specification. Figure 2 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0029] like Figures 2-4 As shown, this embodiment includes a pneumatic catapult 4, an infrared sensor 5, a control switch, a control system, and a cable 6. When the mixed tower construction platform 2 tilts, the infrared sensor 5 immediately sends a platform tilt signal to the control system. The control system then immediately controls the pneumatic catapult 4 to work, causing the launching rod 42 to be fired into the tower wall 1 and anchored. At this time, the cable 6 is in a tensioned state, which can support the mixed tower construction platform 2, prevent it from tilting, and ensure its balance.

[0030] like Figure 1 As shown, the pneumatic catapult 4 includes a launch tube 41, a launch rod 42 nested in the launch tube 41, and a pneumatic drive mechanism 43. The output end of the pneumatic drive mechanism 43 is connected to the launch rod 42.

[0031] The pneumatic drive mechanism 43 includes a high-pressure gas cylinder 431, a gas pipe 432, and a solenoid valve. One end of the gas pipe 432 is inserted into the high-pressure gas cylinder 431, and the other end extends through the left end of the launch tube 41 and into the interior of the launch rod 42. The end of the gas pipe 432 that extends into the launch rod 42 is the output end of the pneumatic drive mechanism 43. The solenoid valve is fixed to the gas pipe 432 (not shown in the figure). The solenoid valve can control the release speed and pressure of the high-pressure gas cylinder 431, thereby adjusting the range. The control system is electrically connected to the pneumatic drive mechanism 43, that is, the control system is electrically connected to the solenoid valve. Controlling the launch rod 42 to launch via the pneumatic drive mechanism 43 is prior art; see patent publication CN213445118U for details. During operation, the control system controls the solenoid valve to open, and the high-pressure gas in the high-pressure gas cylinder 431 is transmitted to the launch rod 42 through the gas pipe 432. The launch rod 42 is then ejected under high pressure and shot towards the tower wall 1.

[0032] like Figure 2-4 As shown, the launching direction of the launching rod 42 is radial along the construction platform 2, and the end of the launching rod 42 away from the launching cylinder 41 (i.e., the right end) faces the tower wall 1. The end of the launching rod 42 away from the launching cylinder 41 is set as a pointed structure. In this embodiment, an anchoring unit 7 is provided at the right end of the launching rod 42. The anchoring unit 7 is a pointed structure, and the right end of the anchoring unit 7 is the most pointed. In this embodiment, on the vertical projection plane, as shown... Figure 2As shown, the anchoring unit 7 is arrow-shaped, with the apex of the arrow located at the end furthest from the launching tube 41. Both the launching rod 42 and the anchoring unit 7 are made of alloy steel, resulting in higher strength. The material of the anchoring unit 7, combined with its pointed structure, allows the anchoring unit 7 to smoothly penetrate and anchor into the tower wall 1 when the launching rod 42 is fired towards the tower wall 1. Of course, in this embodiment, the right end of the launching rod 42 can also be directly machined into a pointed structure, as long as it can penetrate the tower wall 1.

[0033] like Figure 2 As shown, one end of the cable 6 is fixedly connected to the launching tube 41, and the other end is fixedly connected to the launching rod 42. After the launching rod 42 fires the cable, the cable 6 is in a taut state. In this embodiment, the cable 6 is a steel wire rope.

[0034] In this embodiment, the left end of the cable 6 is fixed by a winding roller 8, which includes a drum 81. The left end of the cable 6 is fixed and wound around the drum 81 to neatly and orderly wind up the cable 6. A circular baffle 82 is fixed to each end of the drum 81 to prevent the cable 6 from coming off. The winding roller 8 is rotatably mounted on the launching drum 41. Specifically, a bearing is provided between the winding roller 8 and the launching drum 41. The inner ring of the bearing is fixedly connected to the launching drum 41, and the outer ring of the bearing is fixedly connected to the inner wall of the drum 81. The rotation axis of the winding roller 8 is the same as the central axis of the launching drum 41. When the right end of the cable 6 is pulled, the winding roller 8 rotates to unwind. It should be noted that the left end of the cable 6 is secured to the drum 81 by a wedge block device to meet the requirements of safety and stability. This fixing method is the same as the method of fixing the rope on the drum in a winch, and will not be described in detail here.

[0035] The end of cable 6 furthest from the winding roller 8 (i.e., the right end) is fixedly connected to the launching rod 42 via a lug plate 9. The lug plate 9 is also made of alloy steel and is fixedly mounted on the launching rod 42. Specifically, the lug plate 9 has a through hole, through which the right end of cable 6 passes and wraps around the lug plate 9, and is secured by a wire rope clip. The wire rope clip structure is existing technology. Figure 2 Not shown in the image.

[0036] To achieve automated operation, this embodiment includes an infrared sensor 5, a control system, and a control switch.

[0037] like Figure 2 As shown, the infrared sensor 5 is fixed on the outer wall of the transmitting tube 41 and is used to monitor the balance status of the hybrid tower construction platform 2 in real time; the structure and working principle of the infrared sensor 5 are existing technologies.

[0038] The control system and infrared sensor 5 are both electrically connected to the control switch. When the control switch is turned on, both the control system and infrared sensor 5 are in working condition. The solenoid valve and infrared sensor 5 in the pneumatic drive mechanism 43 are both electrically connected to the control system. The control system and control switch are existing technologies and will not be described in detail in this embodiment.

[0039] In this embodiment, during installation, if... Figure 3 As shown, multiple anchoring units 7 are fixed at intervals along the circumference of the mixed tower construction platform 2 at the bottom of the mixed tower construction platform 2, with the anchoring units 7 close to the edge of the mixed tower construction platform 2. Figure 3 Four illustrations of this embodiment are shown below. The pneumatic catapult 4 is fixed to the bottom of the mixed-tower construction platform 2 using a U-shaped clamp (not shown in the figure). The control switch and control system are located on the mixed-tower construction platform 2. The four infrared sensors are electrically connected to the control switch and control system, and the four solenoid valves are electrically connected to the control system. This embodiment has a simple structure, small size, and is easy to install and maintain.

[0040] The operating state of this embodiment is as follows: the control switch is on, and the infrared sensor 5 and control system are in working condition. At this time, the infrared sensor 5 sends a signal to the control system that the hybrid tower construction platform 2 is in a balanced state. When the chain breaks, the hybrid tower construction platform 2 will tilt. At this time, the infrared sensor 5 will immediately generate a platform tilt signal and send the signal to the control system. The control system will immediately control the solenoid valve in the pneumatic drive mechanism 43 to open. The high-pressure gas in the high-pressure gas cylinder 431 is transmitted to the launching rod 42 through the gas pipe 432. The launching rod 42 is subjected to high pressure and is ejected from the launching cylinder 41, which simultaneously drives the cable 6 to be ejected towards the tower wall 1 and anchored. See Figure 4 , Figure 4 The drawing only shows one launcher 42 firing into the tower wall 1 as an illustration. In actual application, Figure 4 The four launch rods 42 will launch simultaneously. When the launch rods 42 are anchored inside the tower wall 1, the cable 6 is in a taut state, which can support the mixed tower construction platform 2 from the bottom. This achieves adaptive dynamic support for the mixed tower construction platform 2 when the chain breaks, quickly stops the imbalance, ensures the stability of the mixed tower construction platform 2, and protects the lives of the construction personnel on the mixed tower construction platform 2.

[0041] 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.
