Description

Technical Field

[0001] This utility model belongs to the field of flexible lifting door technology, specifically relating to a hook-type movable pulley device for a flexible lifting door. Background Technology

[0002] Flexible lifting gates are gates made of high-strength flexible materials, featuring lightweight construction, wind pressure resistance, thermal insulation, and excellent sealing. They are suitable for large workshops, warehouses, logistics centers, and other similar locations. The following is a detailed introduction to flexible lifting gates: Structural Composition: Gate Body: Typically composed of two layers of polyester fiber door fabric, connected by an aluminum crossbeam to form a vertical lifting structure. Drive System: Includes a motor, reducer, drum, and other components used to drive the lifting of the gate body. Guide Rail System: Made of high-strength aluminum alloy or galvanized steel to ensure the stability and safety of the gate body during lifting. Control System: Equipped with an intelligent control box, supporting multiple operating modes such as remote control and automatic control to ensure efficient operation of the gate. Safety Devices: Includes anti-fall devices, limit switches, and audible and visual alarms to ensure the safety of the gate body during lifting.

[0003] Existing large flexible doors use two separate units for both the pulley and the anti-fall structure. The pulley and the anti-fall component are each an independent system. The existing configuration has high production costs, is cumbersome to install, and is complex to operate. Subsequent inspection, repair, and maintenance are also very inconvenient. Furthermore, the large number of ropes required for lifting can affect the rotation of the anti-fall structure, potentially causing interference and resulting in poor working stability of the anti-fall structure. This makes it very easy for the flexible lifting door to suddenly fall and fail to lock in time. Utility Model Content

[0023] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:

[0024] A flexible lifting gate hook-type movable pulley device includes,

[0025] Lifting plate 1;

[0026] A hook assembly is located on the outer wall of the lifting plate 1. The hook assembly includes a mounting platform 2, a first pin 3, a rotating hook 4, a second pin 5, a conveying wheel 6, a third pin 7, a guide wheel 8, and a moving groove 101. The moving groove 101 is located on the outer wall of the lifting plate 1 near the bottom. The mounting platform 2 is fixedly located on the outer wall of the lifting plate 1 near the bottom. The first pin 3 is embedded in the inner wall opening of the mounting platform 2. The rotating hook 4 is rotatably sleeved on the outer wall of the first pin 3. The second pin 5 is embedded in the outer wall opening of the rotating hook 4. The conveying wheel 6 is rotatably sleeved on the outer wall of the second pin 5. The third pin 7 is embedded in the outer wall opening at one end of the rotating hook 4. The guide wheel 8 is rotatably sleeved on the outer wall of the third pin 7. The moving groove 101 and the rotating hook 4 are matched with each other.

[0027] In a specific embodiment of the present utility model, the hook assembly combines the conveying wheel 6, the guiding wheel 8, and the rotating hook 4, which not only saves production and installation costs, but also has high production and installation efficiency and superior performance. The user has highly evaluated the anti-wind, bearing, safety, and operation effects after using this design, technology, and equipment. At the same time, it does not hinder the operation of the steel wire rope and reduces the possibility of interference. First, the lifting plate 1 is installed at the designated working position. As the large flexible door rises or falls, the flexible door is constrained inside the slide rail, and the slide rail is equally spaced on the circular limiting posts. Subsequently, the steel wire rope supporting the flexible door is wound around the inner wall of the conveying wheel 6, and the guiding wheel 8 is used for constraint and resistance reduction to avoid direct friction with the rotating hook 4. When the flexible door gets out of control, the external cylinder pushes one end of the rotating hook 4, causing the rotating hook 4 to quickly rotate around the installation platform 2. Finally, without affecting the steel wire rope, the bent end of the rotating hook 4 is clamped onto the circular limiting post on the slide rail of the flexible door, completing the locking of the flexible door to prevent it from falling uncontrollably.

[0028] Specifically, the outer wall of the conveying wheel 6 is recessed.

[0029] In a specific embodiment of the present utility model, the outer wall of the conveying wheel 6 is recessed to prevent the steel wire rope from slipping off.

[0030] Specifically, the outer wall of the guiding wheel 8 is recessed, and the conveying wheel 6 and the guiding wheel 8 match each other.

[0031] In a specific embodiment of the present utility model, the conveying wheel 6 and the guiding wheel 8 match each other to ensure the stable movement of the steel wire rope.

[0032] Specifically, auxiliary frames 9 are fixedly arranged on both sides near the top of the outer wall of the lifting plate 1.

[0033] In a specific embodiment of the present utility model, auxiliary frames 9 are fixedly arranged on both sides near the top of the outer wall of the lifting plate 1, which can facilitate the deployment of other sensors.

[0034] Specifically, one end of the rotating hook 4 is bent.

[0035] In a specific embodiment of the present utility model, one end of the rotating hook 4 is bent to ensure that it can hook the slide rail.

[0036] Specifically, the other end of the rotating hook 4 protrudes outward.

[0037] In a specific embodiment of the present utility model, the other end of the rotating hook 4 protrudes outward, which can facilitate the external cylinder to push for rotation.

[0038] Working principle:

[0039] The hook assembly combines the conveying wheel 6, the guiding wheel 8 and the rotating hook 4, which not only saves the production and installation costs, but also has high production and installation efficiency and superior performance. The user has highly evaluated the anti-wind, bearing, safety and operation effects after using this design, technology and equipment. At the same time, it does not hinder the operation of the steel wire rope and reduces the possibility of interference. First, install the lifting plate 1 at the designated working position. Along with the rise or fall of the large flexible door, at the same time, the flexible door is constrained inside the slide rail, and the slide rail is equally spaced on the circular limit posts. Subsequently, wind the steel wire rope matching the flexible door around the inner wall of the conveying wheel 6, and the guiding wheel 8 is used for constraint and resistance reduction to avoid direct friction with the rotating hook 4. When the flexible door gets out of control, the external cylinder pushes one end of the rotating hook 4, making the rotating hook 4 rotate rapidly around the mounting table 2. Finally, without affecting the steel wire rope, the bent end of the rotating hook 4 is clamped to the circular limit post on the slide rail of the flexible door, completing the locking of the flexible door and preventing it from falling uncontrollably.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
