Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to a linkage device for inner and outer doors of a garage vehicle entrance and exit. Background Art
[0002] In a multi-story parking garage, separate vehicles are used for access and storage. Typically, two doors are installed at the vehicle entrance and exit: an inner door near the elevator access and an outer door away from the access. When parking a vehicle, the inner door is closed and the outer door is opened. After the vehicle enters the entrance and the driver leaves, the outer door is closed and the inner door is opened, allowing a transporter to enter and transport the vehicle to be stored. Currently, each outer and inner door is driven by a separate motor. To avoid uneven force from the motor acting on one side, a counterweight is required to ensure uniform force on the motor when opening and closing the door, thereby extending the motor's lifespan. However, this not only complicates the structure but also increases production costs.
[0003] Therefore, in the field of stereo garage technology, there is still a need for research and improvement on the linkage device of the inner and outer doors of garage vehicle entrances and exits. This is also a research hotspot and focus in the current field of stereo garage technology, and it is also the starting point for the completion of this utility model. Utility Model Content
[0004] Therefore, the technical problem to be solved by the present invention is to provide a linkage device for inner and outer doors of a garage vehicle entrance and exit, so as to solve the technical problems of complex structures of inner and outer doors and high production costs.
[0005] In order to solve the above technical problems, the technical solution of the utility model is: a garage vehicle entrance and exit inner and outer door linkage device, including tracks arranged on both sides of the vehicle entrance and exit, inner door and outer door are vertically slidably installed on the tracks, a rotating shaft driven by a power device is provided in the vehicle entrance and exit, an inner traction rope and an outer traction rope are provided on the rotating shaft, one end of the inner traction rope is fixed to the rotating shaft, and the other end of the inner traction rope is wrapped around the rotating shaft and fixed to the inner door, one end of the outer traction rope is fixed to the rotating shaft, and the other end of the outer traction rope is wrapped around the rotating shaft and fixed to the outer door, and the winding directions of the inner traction rope and the outer traction rope on the rotating shaft are opposite.
[0006] As an improvement, two groups of inner traction ropes and outer traction ropes are provided.
[0007] As a further improvement, the winding directions of the two groups of inner traction ropes are the same, and the winding directions of the two groups of outer traction ropes are the same.
[0008] After adopting the above technical solution, the beneficial effects of the utility model are:
[0009] The utility model provides a linkage device for inner and outer doors of a garage vehicle entrance and exit, in which the inner traction rope and the outer traction rope are wound on the rotating shaft in opposite directions and are driven by a motor reducer, which saves production costs. In addition, the inner and outer traction ropes are both wound on the same rotating shaft, so that the inner door and the outer door serve as counterweights for each other, reducing the use of counterweights, and evenly applying force to the rotating shaft, thereby reducing power loss and thereby reducing the rated power of the motor reducer.

[0018] like Figure 1 and Figure 2 As shown in the figure, a linkage device for inner and outer doors 5 of a garage entrance and exit comprises tracks 3 arranged on both sides of a vehicle entrance and exit 1, and an inner door 4 and an outer door 5 are vertically slidably installed on the tracks 3. As a commonly used technical means, the inner door 4 is close to the lifting channel 2, and the outer door 5 is away from the lifting channel 2. Both the inner door 4 and the outer door 5 adopt multi-section lifting doors, which are commonly used products in this field and can be directly purchased and used. No further details are given here. The two tracks 3 are arranged in parallel, and the two tracks 3 extend from one side of the inner door 4 to the other side of the outer door 5. Rollers are installed on both sides of the inner door 4 and the outer door 5, and all rollers are slidably installed in the tracks 3 on the corresponding side. A rotating shaft 7 driven by a power device is provided in the vehicle entrance and exit 1. The rotating shaft 7 is rotatably installed in a fixed position of the vehicle entrance and exit 1 through a bearing seat, and is usually arranged in the top middle position of the vehicle entrance and exit 1. The power device is preferably a motor reducer 6, and the motor reducer 6 is connected to the rotating shaft 7 through a gear pair or a chain drive, such as Figure 3 As shown, an inner traction rope 8 and an outer traction rope 9 are provided on the rotating shaft 7, one end of the inner traction rope 8 is fixed on the rotating shaft 7, and the other end of the inner traction rope 8 is wrapped around the rotating shaft 7 and fixed to the inner door 4, one end of the outer traction rope 9 is fixed on the rotating shaft 7, and the other end of the outer traction rope 9 is wrapped around the rotating shaft 7 and fixed to the outer door 5, the inner traction rope 8 and the outer traction rope 9 are wound in opposite directions on the rotating shaft 7, and are driven by a motor reducer 6, which saves production costs, and the inner traction rope 8 and the outer traction rope 9 are both wrapped around the same rotating shaft 7, so that the inner door 4 and the outer door 5 serve as counterweights to each other, reducing the use of counterweights, and the rotating shaft 7 is evenly stressed, which reduces power loss, thereby reducing the rated power of the motor reducer 6.
[0019] Specifically, there are two groups of inner traction ropes 8 and outer traction ropes 9, both of which are steel ropes. The winding directions of the two groups of inner traction ropes 8 are the same, and the ends are fixed on both sides of the inner door 4 respectively. The winding directions of the two groups of outer traction ropes 9 are the same, and the ends are fixed on both sides of the outer door 5 respectively, so that the inner door 4 and the outer door 5 are subjected to balanced force on both sides when lifting or lowering, reducing the jamming of the inner door 4 and the outer door 5 during operation.
[0020] The utility model provides a linkage device for the inner and outer doors 5 of the garage entrance and exit, in which the inner door 4 and the outer door 5 are linked. When the inner door 4 is closed, the outer door 5 opens, and when the outer door 5 is closed, the inner door 4 opens. The inner door 4 and the outer door 5 counterweight each other, thereby reducing the need for additional counterweight, and the rotating shaft 7 is evenly stressed, thereby reducing the rated power of the motor reducer 6, thereby reducing the production cost.
[0021] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
