Description

Technical Field

[0001] This utility model relates to a guardrail gate, specifically a liftable guardrail gate. Background Technology

[0002] In today's buildings, industries, and various other venues, security gates play a crucial role as an important component in ensuring the safety of people and property.

[0003] However, most existing traditional guardrail gates are fixed structures. Once installed, their position and height are fixed, lacking flexibility. In actual production, however, there are occasions where temporary passageways need to be opened, such as the movement of large equipment or emergency rescue. Fixed guardrail gates become obstacles, affecting the safety, convenience, and efficiency of production. Utility Model Content

[0004] The purpose of this invention is to provide a liftable guardrail gate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liftable gate includes two opposing posts, a transmission device mounted on the posts, a lifting device fixedly connected to the transmission device, and a gate fixedly connected to the lifting device. The transmission device provides power and a transmission path to the lifting device, thereby driving the gate to rise and fall.

[0007] As a further embodiment of this utility model: the column has a C-shaped structure, with the openings of the two columns facing each other.

[0008] As a further embodiment of this utility model: the transmission device includes a motor, a rotating shaft, a guide shaft, a sprocket, and a chain. The rotating shaft passes through the upper ends of the two columns. One end of the rotating shaft passes through one side column and is fixedly connected to the output end of the motor. The other end of the rotating shaft is rotatably connected to the inner wall of the other side column. The lower ends of the two columns are respectively rotatably connected to the guide shaft. Sprockets are fixedly connected at corresponding positions of the two guide shafts and the rotating shaft in the two columns. A chain meshes between the upper and lower sprockets in each side column.

[0009] As a further embodiment of this utility model: the lifting device includes a connecting plate, a vertical slider, a guide linear bearing, and a guide rod. One side of the connecting plate is fixedly connected to the chain, and the other side is fixedly connected to the guardrail gate. A vertical slider is fixedly connected to the connecting plate, and a guide linear bearing is installed on the vertical slider. The guide rod is fixedly connected to the column and extends from the upper end to the lower end of the column along the length direction of the column. The guide linear bearing is slidably connected to the guide rod.

[0010] As a further improvement of this utility model: a protective cover is provided on the outside of the rotating shaft, and the protective cover is fixedly connected to the column; a motor cover is provided on the outside of the motor, and the motor cover is fixedly connected to the column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: A liftable guardrail gate is driven to rise and fall smoothly through a transmission device and a lifting device. In the transmission device, a motor, a rotating shaft, a guide shaft, a sprocket, and a chain work together. The motor drives the rotating shaft to rotate, and power is transmitted through the meshing of the sprocket and the chain. The lifting device includes a connecting plate, a vertical slider, a guide linear bearing, and a guide rod. The connecting plate is connected to the chain and the guardrail gate. The smooth rise and fall of the guardrail gate is achieved by the sliding of the guide linear bearing on the guide rod. This allows the guardrail gate to be opened quickly when it is necessary to temporarily open a passage or load and unload goods, ensuring the safety, convenience, and efficiency of production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5In this embodiment of the utility model, a liftable guardrail gate includes two opposing columns 1. A transmission device 2 is installed on the column 1, and a lifting device 3 is fixedly connected to the transmission device 2. A guardrail gate 4 is fixedly connected to the lifting device 3. The transmission device 2 provides power and transmission path to the lifting device 3, thereby driving the guardrail gate 4 to rise and fall.

[0020] The column 1 has a C-shaped structure, with the openings of the two columns 1 facing each other.

[0021] The transmission device 2 includes a motor 21, a rotating shaft 22, a guide shaft 23, a sprocket 24, and a chain 25. The rotating shaft 22 passes through the upper ends of the two columns 1. One end of the rotating shaft 22 passes through one side column 1 and is fixedly connected to the output end of the motor 21. The other end of the rotating shaft 22 is rotatably connected to the inner wall of the other side column 1. The guide shaft 23 is rotatably connected to the lower ends of the two columns 1 respectively. Sprockets 24 are fixedly connected to the corresponding positions of the two guide shafts 23 and the rotating shaft 22 in the two columns 1 respectively. A chain 25 is meshed between the upper and lower sprockets 24 in each side column 1.

[0022] The lifting device 3 includes a connecting plate 31, a vertical slider 32, a guide linear bearing 33, and a guide rod 34. One side of the connecting plate 31 is fixedly connected to the chain 25, and the other side is fixedly connected to the guardrail gate 4, thereby establishing a linkage relationship between the chain 25 and the guardrail gate 4. The vertical slider 32 is fixedly connected to the connecting plate 31, and the guide linear bearing 33 is installed on the vertical slider 32. The guide rod 34 is fixedly connected to the column 1 by welding or bolting, and extends from the upper end to the lower end of the column 1 along the length direction of the column 1. The guide linear bearing 33 is slidably connected to the guide rod 34.

[0023] In addition, to ensure safety and equipment protection, a protective cover 5 is provided on the outside of the rotating shaft 22, and the protective cover 5 is fixedly connected to the column 1. A motor cover 6 is provided on the outside of the motor 21, and the motor cover 6 is fixedly connected to the column 1.

[0024] The working principle of this utility model is as follows: When the guardrail gate 4 needs to be operated, the motor 21 is started. The output end of the motor 21 drives the rotating shaft 22, which is fixedly connected to it, to rotate. The rotation of the rotating shaft 22 drives the sprocket 24, which is fixedly connected to it, to rotate synchronously. The sprocket 24 drives the chain 25 to move up and down in a circular motion along the direction of the column 1. The connecting plate 31, which is fixedly connected to the chain 25, moves up and down with the movement of the chain 25. Since the other side of the connecting plate 31 is fixedly connected to the guardrail gate 4, the movement of the connecting plate 31 directly drives the guardrail gate 4 to rise and fall. During the rising and falling process, the vertical slider 32 moves together with the connecting plate 31. The guide linear bearing 33 installed on the vertical slider 32 slides smoothly on the guide rod 34. The guide rod 34 extends from the upper end to the lower end along the column 1, providing stable guide support for the entire rising and falling movement, ensuring that the guardrail gate 4 can only rise or fall smoothly in the vertical direction, avoiding swaying, deviation, etc. When the guardrail gate 4 reaches the required opening or closing position, the motor 21 is turned off, and the guardrail gate 4 is fixed in the current position.

[0025] 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
