Description
Technical Field
[0001] This utility model relates to the field of tower operation technology, and more specifically to the field of a flexible opening and closing device for a tower platform cover. Background Technology
[0002] Traditional tower crane operations rely on manual climbing, which severely limits the efficiency and safety of personnel ascending the tower. With the development of automation technology, tower crane operations are now beginning to use non-climbing devices. However, using a single non-climbing device for tower climbing has the following shortcomings:
[0003] 1. The platform cover inside the tower cannot open automatically and cannot coordinate with the climbing device, which means that workers still need to manually open and close the cover when climbing the tower. This operation is too troublesome and it is easy for the cover to be left open after passing through.
[0004] 2. When multiple people are working on the tower, the cover plate cannot be closed in time, which increases the safety hazards of the operation.
[0005] Therefore, in order to improve the safety, standardization and efficiency of operations inside wind turbine towers, there is an urgent need for a flexible opening and closing device for tower platform covers that can work in conjunction with a climb-free device. Utility Model Content
[0006] The purpose of this utility model is to solve the technical problem that when the automatic opening and closing function fails due to the use of rigid components for transmission, the platform cover cannot be manually opened and closed, which will hinder the operators from climbing the tower, seriously affect the operation efficiency, and increase the operation cost. This utility model provides a flexible opening and closing device for the tower platform cover.
[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0008] One aspect of this utility model provides a flexible opening and closing device for a tower platform cover, including an upper sensing sensor installed above the tower platform, a lower sensing sensor installed below the tower platform, a cover plate hinged to an opening in the tower platform, a flexible drive mechanism installed on the tower platform and driving the cover plate to open and close, an image monitoring module installed on the tower platform, and a measurement and control host.
[0009] The upper and lower sensing sensors are connected to the signal input terminals of the measurement and control host; the flexible drive mechanism is connected to the signal output terminal of the measurement and control host.
[0010] Specifically, the monitoring and control host receives signals from the sensors (upper and lower sensors) and determines the opening and closing of the cover. A flexible connecting rod connects the cover and the monitoring and control host, transmitting the power required for the cover's opening and closing. All signals between components within the system are transmitted via wired connections. It can be installed and used independently and is compatible with various brands of non-climbing devices / lifts; it supports three operating modes: automatic sensor triggering, manual button triggering, and manual opening and closing.
[0011] The flexible linkage structure of this utility model ensures that the platform cover can still be manually opened and closed even if the automatic opening and closing fails due to power failure or other factors, without hindering tower operation and maintenance.
[0012] The device's opening and closing power is transmitted through a flexible linkage structure, preventing the cover from being accidentally locked.
[0013] In one embodiment, the monitoring and control host includes a controller fixed on the tower platform, and both the upper and lower sensing sensors are connected to the signal input terminal of the controller.
[0014] In one embodiment, the flexible drive mechanism includes a flexible rope, a drive motor, and a winch disposed at the output end of the drive motor. One end of the flexible rope is connected to a cover plate, and the other end of the flexible rope is wound around the winch. The drive motor is fixed to a controller and is signal-connected to the signal output end of the controller. The drive motor is a variable frequency motor.
[0015] In one embodiment, the system also includes an image monitoring module for real-time monitoring of the current operating status of the cover plate, and the image monitoring module is connected to a host computer via signal.
[0016] In one embodiment, the cover plate is rotatable from 0 to 90 degrees about the hinge point.
[0017] In one embodiment, it also includes an upper manual trigger button installed above the tower platform and a lower manual trigger button installed below the tower platform; both the upper and lower manual trigger buttons are connected to the signal input terminal of the controller.
[0018] Specifically, when people climb the ladder to the top of the tower, the cover can be opened and closed automatically by manually triggering a button.
[0019] In one embodiment, both the upper and lower sensing sensors are installed on the inner side of the tower ladders on the upper and lower sides of the cover plate.
[0020] In one implementation, the telemetry and control host is mounted on the tower platform.
[0021] Another aspect of this utility model provides a tower, including the above-mentioned flexible opening and closing device for a tower platform cover.
[0022] In one embodiment, the tower body includes a ladder vertically mounted on the inner wall of the tower body and multiple tower platforms spaced axially on the inner wall of the tower body. Each tower platform is provided with a platform through-hole that allows ladders and workers to pass through, and a cover plate is hinged to the platform through-hole.
[0023] The working principle of this utility model is as follows: The opening and closing timing of the cover is coordinated by the sensors on the upper and lower sides of the platform. When moving upwards, the lower sensor is triggered first, and the platform cover opens automatically. After a person passes through the platform cover, the upper sensor is triggered, and the platform cover closes automatically. When moving downwards, the upper sensor is triggered first, and the platform cover opens automatically. After a person passes through the platform cover, the lower sensor is triggered, and the platform cover closes automatically.
[0024] like Figure 1 As shown, the flexible opening and closing device for the tower platform cover enables sensing of the climbing device / lift and its running direction. This flexible opening and closing device is installed and used independently and is compatible with various brands of climbing devices / lifts. It supports three working modes: automatic sensing trigger, manual button trigger, and manual opening and closing. The workflow is as follows: Figure 2 As shown.
[0025] The beneficial effects of this utility model are as follows:
[0026] (1) This utility model does not change the original cover plate structure. The device is lightweight, easy to transport, simple to install, and ready to use immediately. The whole machine is compact, minimizing the platform space occupancy rate.
[0027] (2) The flexible linkage structure of this utility model ensures that the platform cover can still be opened and closed manually in the event of power failure or other factors that cause the automatic opening and closing to fail, without hindering the tower operation and maintenance.
[0028] (3) This utility model can be installed and used independently and can be adapted to various brands of climbers / lifts; it supports three working modes: automatic sensing trigger, manual button trigger and manual opening and closing. Attached Figure Description
