Description

Technical Field

[0001] This utility model relates to the field of flexible lifting gate technology, and more specifically, to a stall brake device for a power winch of a flexible lifting gate. Background Technology

[0002] Flexible lifting gates, also known as special flexible gates, are a type of gate suitable for special industrial environments. They are made of high-strength flexible materials, such as PVC curtains, offering excellent impact and wind resistance. The gate is sealed with two layers of fabric, connected by aluminum or steel beams, and features movable guide rails during lifting. These gates are lightweight, aesthetically pleasing, easy to install and maintain, while also meeting the requirements for rapid opening and closing.

[0003] A winch is a mechanical device that uses a drum to wind a steel wire rope or chain to lift or pull heavy objects. It is widely used in construction, engineering, shipping, mining and other fields. The selection of a winch should take into account factors such as load, speed, frequency of use and environmental conditions according to the actual working conditions to ensure safe and reliable operation.

[0004] Existing large flexible gate winches are equipped with brakes, which are usually power-off braking brakes. During the use of the gate, if the connecting shafts such as the drum shaft and reducer shaft break, the braking effect will be poor or even the braking function will be lost, making it difficult to meet safety requirements and unsuitable for use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Example:

[0025] Please see Figure 1-3 A stall brake device for a power winch of a flexible lifting gate includes: a main mounting frame 1, a geared motor 2 mounted on one outer wall of the main mounting frame 1, a power failure brake 3 mounted on the output end of the geared motor 2, and a wire drum body 4 detachably connected to the output end of the main mounting frame 1; and a braking assembly, which includes: an axle brake component and an auxiliary brake component. The axle brake component includes: a drum mounting frame 5, a shaft seat, and a circular stall brake 6. The drum mounting frame 5 is located on one side of the main mounting frame 1. The shaft seat is detachably connected to the top surface of the drum mounting frame 5, and one outer wall of the shaft seat is rotatably connected to one end of the wire drum body 4. The circular stall brake 6 is mounted on one outer wall of the wire drum body 4. The auxiliary brake component is located on one side of the drum mounting frame 5 to assist the axle brake component in braking operation.

[0026] In a specific embodiment of this utility model, a reduction motor 2, a power failure brake 3, and a wire reel 4 are installed on the main mounting frame 1. The wire reel 4 winds and pulls the steel wire. The power failure brake 3 controls the reduction motor 2. In case of an accident, the circular stall brake 6 further brakes the wire reel 4. Thus, even if the connecting shafts such as the reel shaft and the reduction gear shaft break, it still has a braking effect. The braking effect of the circular stall brake 6 is further improved by the auxiliary braking components. Additional braking is performed by the friction between the external friction brake disc 8 and the external auxiliary braking extension 7, thereby improving the safety of the flexible lifting gate during use.

[0027] Specifically, the auxiliary braking components include: an external friction brake disc 8, a side extension fixing frame 9, two side brake electric push rods 10, a central movable connecting frame 11, and multiple movable rods 12. The side extension fixing frame 9 is fixedly connected to one side of the outer wall of the drum mounting frame 5. The two side brake electric push rods 10 are both installed on one side of the outer wall of the side extension fixing frame 9. The central movable connecting frame 11 is detachably connected between the output ends of the two side brake electric push rods 10. The multiple movable rods 12 are all fixedly connected to one side of the outer wall of the central movable connecting frame 11. The external friction brake disc 8 is fixedly connected between one end of the multiple movable rods 12.

[0028] In this embodiment, a side brake electric push rod 10 is installed by a side extension fixing frame 9. The side brake electric push rod 10 pushes the central movable connecting frame 11 and the movable rod 12 to move. The movable rod 12 then pushes the external friction brake disc 8 and the external auxiliary brake extension 7 to contact, thereby improving the braking effect.

[0029] Specifically, the outer wall of the circular stall brake 6 is provided with an outer auxiliary braking extension 7, which cooperates with the outer friction brake disc 8.

[0030] In this embodiment, further braking is achieved through the friction between the external auxiliary braking extension 7 and the external friction brake disc 8.

[0031] Specifically, two limiting rods 13 are fixedly connected to one side of the outer wall of the roll mounting frame 5, and both limiting rods 13 movably pass through the movable connecting frame 11.

[0032] In this embodiment, the movement of the movable connecting frame 11 is guided by the limiting rod 13 to prevent it from deviating.

[0033] Specifically, a limiting plate is fixedly connected between one end of the two limiting rods 13.

[0034] In this embodiment, the maximum movement position of the movable connecting frame 11 is limited by the limiting plate, while preventing the movable connecting frame 11 from falling off.

[0035] Specifically, a bracket is provided on one side of the outer wall of the side extension fixing frame 9. The outer wall of one side of the bracket is fixedly connected to the outer wall of one side of the drum mounting frame 5, and the bracket and the middle movable connecting frame 11 are slidably engaged.

[0036] In this embodiment, the movable connecting frame 11 is moved with the assistance of the bracket, which facilitates the installation operation.

[0037] Working principle: The main mounting frame 1 houses the geared motor 2, the power failure brake 3, and the wire reel 4. The wire reel 4 winds and pulls the steel wire. The power failure brake 3 controls the geared motor 2. In case of an accident, the circular stall brake 6 further brakes the wire reel 4. This ensures that even if the connecting shafts such as the reel shaft and gearbox shaft break, the braking effect is still achieved. The braking effect of the circular stall brake 6 is further enhanced by the auxiliary braking components. Additional braking is achieved through the friction between the external friction brake disc 8 and the external auxiliary braking extension 7, improving the safety of the flexible lifting gate during use.

[0038] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
