Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of large building structures, and more particularly to a track slot shielding system for a movable roof and a control method thereof, which is particularly suitable for a movable roof system of an irregular large cantilevered space. BACKGROUND
[0002] Modern large sports venues, exhibition centers and other buildings often use retractable roof structures to meet the needs of lighting, ventilation and all-weather use. The movable roof usually moves on a fixed track, which forms an exposed track slot. The long-term exposure of the track slot not only affects the beauty of the interior of the building, but also easily accumulates dust and debris. Rainwater or lubricating grease may also drip through the slot, affecting the use of the space below.
[0003] In the prior art, some use a simple fixed cover plate, but it will hinder the movement of the movable roof. Some use a whole movable cover plate, but it requires a huge installation and storage space, occupies a large space, has a high cost, and is difficult to match with irregular roofs. In particular, for systems with irregular shapes, large cantilevers, and very small gaps between the movable roof and the fixed roof, traditional covering solutions are almost impossible to implement. Therefore, there is an urgent need for an intelligent covering system that can effectively cover in a very small space without interfering with the movement of the roof. SUMMARY
[0004] The present application provides a track slot shielding system for a movable roof and a control method thereof, which aims to solve the problem of covering the track slot under the condition that the gap between the movable roof and the fixed roof is very small, and to ensure that the covering action is precisely coordinated with the movement of the roof.
[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a track slot shielding system for a movable roof, which is installed below the track slot of the movable roof structure, comprising a plurality of shielding units arranged in sequence along the length direction of the track slot, each shielding unit comprising a cover plate, an electric push rod and a turnover mechanism, the cover plate being hinged to the movable roof, one end of the turnover mechanism being hinged to the extension end of the electric push rod, and the other end being hinged to the cover plate, the electric push rod driving the turnover mechanism to rotate, and the cover plate being switched between the closed position covering the track slot and the open position avoiding the movement of the movable roof.
[0006] Further, the turnover mechanism is a linkage mechanism, comprising a driving linkage and a driven linkage, the driving linkage being hinged to the movable roof through a support, the two ends of the driving linkage being hinged to the extension end of the electric push rod and the driven linkage, respectively, and the cover plate being fixed with a support two hinged to the other end of the driven linkage.
[0007] Further, the cylinder of the electric push rod is hinged to the movable roof through a support three.
[0008] Further, the cover plate is flush with the surface of the adjacent fixed roof or movable roof when in the closed position.
[0009] Further, the smart control system is further provided, and the smart control system is in communication connection with all the electric push rods, and specifically includes,
[0010] The position detection module is used for monitoring the displacement of the movable roof in real time.
[0011] The control logic module pre-stores the triggering position information of each covering unit.
[0012] The drive output module sends an action instruction to the corresponding electric push rod according to the position signal.
[0013] Further, the smart control system includes a PLC controller and a displacement encoder, and the displacement encoder is used for monitoring the displacement of the movable roof in real time.
[0014] A method for controlling a track slot shielding system, comprising the following steps:
[0015] The running position of the movable roof is monitored in real time by a displacement sensor.
[0016] When the movable roof moves to a preset closed triggering position, the electric push rods of each covering unit are sequentially started in order from the head to the tail of the roof, so that the cover plates are sequentially turned to the closed position.
[0017] When the movable roof moves to a preset open triggering position, the electric push rods of each covering unit are sequentially started in order from the tail to the head of the roof, so that the cover plates are sequentially turned to the open position.
[0018] Further, during the action of the cover plates, the system continuously monitors the position of the movable roof, and immediately stops the action of the cover plates if an abnormal position is found.
[0019] Compared with the conventional method, the present application has the following beneficial effects:
[0020] 1. Strong space adaptability: The turnover design has very small requirement for vertical installation space, and perfectly solves the covering problem under small gap working conditions.
[0021] 2. Unity of beauty and function: The cover plate is flush with the surrounding roof after being closed, significantly improves the beauty of the building interior, and can effectively prevent dust, sundries and other foreign matters from falling.
[0022] 3. Intelligent collaborative control: Through the sequential control linked with the displacement of the roof, mechanical interference between the cover plate and the moving roof is completely avoided, and the reliability is high.
[0023] 4. Modular design: The segmented design is convenient for manufacturing, installation and maintenance, and the local damage can be replaced individually, thereby reducing the operation and maintenance cost. Attached Figure Description

[0027] The attached diagram is labeled as follows: 1. Electric push rod; 2. Tilting mechanism; 3. Cover plate; 4. Support; 5. Covering unit; 6. Movable roof. Detailed Implementation
[0028] The following is in conjunction with the appendix Figures 1 to 5 The present invention provides a more detailed description of a track groove shielding system and its control method for a movable roof.
[0029] like Figure 1 and Figure 2 As shown, the present invention provides a track trough covering system for a movable roof, comprising multiple covering units 5 arranged sequentially along the length of the track trough. Each covering unit 5 includes a cover plate 3, an electric push rod 1, and a flipping mechanism 2. The electric push rod 1, the cover plate 3, and the flipping mechanism 2 are all mounted on the movable roof structure 6 via supports 4. The supports 4 include support one 41, support two 42, support three 43, and support four 44. Support one 41, support three 43, and support four 44 are all fixedly mounted on the movable roof structure 6 by means of high-strength bolts, providing a stable mounting foundation for the entire covering unit 5. Support two 42 is fixedly mounted on the lower surface of the cover plate 3 for connection with the flipping mechanism 2. The supports 4 are made of Q345B steel, possessing sufficient strength and rigidity.
[0030] The cover plate 3 is hinged to the movable roof 6 via multiple supports 44. The cylinder of the electric push rod 1 is hinged to the support 3 43. The flipping mechanism 2 adopts a linkage structure, wherein the middle part of the active linkage 21 is hinged to the support 1 41 via a pin. The two ends of the active linkage 21 are respectively hinged to the telescopic end of the electric push rod 1 and the driven linkage 22. The other end of the driven linkage 22 is hinged to the support 2 42 on the cover plate.
[0031] The electric actuator 1 is an industrial-grade product with an IP67 protection rating. The thrust is determined based on the size and weight of the cover plate 3, typically using a model with a thrust of 500-2000N. A mechanical limit device is provided at the end of the actuator's stroke to prevent damage from overtravel.
[0032] The cover plate 3 is made of aluminum alloy or stainless steel material and is subjected to corrosion protection treatment. In the closed position, the upper surface of the cover plate 3 is flush with the surface of the adjacent fixed roof or movable roof 6 (the height difference can be controlled within ±3 mm), ensuring a neat and beautiful visual effect.
[0033] When the movable roof needs to be moved, the intelligent control system sends an opening instruction, the telescopic end of the electric push rod moves, the telescopic push rod pulls one end of the driving link 21 hinged thereto, so that the driving link 21 rotates around the hinge point (support one 41) in the middle. The other end of the driving link 21 pulls the driven link 22, which in turn drives the cover plate 3 hinged thereto. Since the cover plate 3 is hinged to the movable roof 6 structure through the support four 44, it is flipped around its own hinge axis under the traction of the link, finally realizing the folding or opening effect of the cover plate. When folding, the cover plate 3 is inclined and suspended on both sides of the track groove, which is the opening position (as shown in Figure 3 、 Figure 4 When the cover plate is flipped to the horizontal state, it finally covers the track groove below. This is the closed position (as shown in Figure 5 When the cover plate is flipped to the horizontal state, it finally covers the track groove below. This is the closed position (as shown in
[0034] The present application provides power through an electric push rod, and uses a link mechanism to accurately convert linear push-pull motion into rotary motion of the cover plate, realizing effective shielding and avoiding action in a very small vertical space, and realizing intelligent collaborative control with the operation of the movable roof.
[0035] The intelligent control system includes a PLC controller and a displacement encoder. The displacement encoder is an absolute value encoder installed on the driving system of the movable roof 6 for real-time monitoring of the displacement of the movable roof 6. The PLC controller serves as the control core and pre-stores the triggering position information of each covering unit 5.
[0036] The specific working process of the control system is as follows:
[0037] When the movable roof 6 moves from the open state to the closed state, the displacement encoder monitors the roof position in real time. When the roof moves to the preset closed triggering position Pn, the PLC controller sends a closing instruction to the electric push rod 1 of the corresponding covering unit 5 in sequence from the head to the tail of the roof, driving the cover plate 3 to flip to the closed position in sequence.
[0038] When the movable roof 6 moves from the closed state to the open state, when the roof moves to the preset open trigger position Qn, the PLC controller sends an open command to the corresponding covering unit 5 in sequence from the tail to the head of the roof, and drives the cover plate 3 to turn to the open position in sequence.
[0039] The preset trigger position is determined according to the action time of the electric push rod 1, the turning speed of the cover plate 3 and the running speed of the movable roof 6, which ensures that the cover plate 3 action is perfectly matched with the roof operation, and avoids interference.
[0040] The system is provided with an abnormality monitoring device, which continuously monitors the position of the movable roof 6 during the action of the cover plate 3, and stops all the actions of the cover plate 3 immediately if the position is found to be abnormal (such as exceeding the expected range or abnormal speed), so as to ensure the safety of the system.
[0041] The present application successfully solves the covering problem of the track groove of the movable roof 6 through the design concept of segmented turning and the intelligent collaborative control method, greatly improves the beauty of the building interior while ensuring the reliability of the function.
[0042] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution belonging to the idea of the present application shall be within the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application shall be considered as the protection scope of the present application.
