Description

Technical Field

[0001] This utility model relates to the technical field of container door structure, specifically to a vertical three-dimensional container double-door combination system. Background Technology

[0002] In existing vertical racking systems, the door opening and closing system has many problems. For large doors, the drive power transmission is unstable, easily leading to uneven opening and closing. For example, Chinese Patent Publication No. CN201542078U discloses a lifting mechanism for a lifting cabinet. Furthermore, during the vertical opening and closing motion, the door is prone to displacement, affecting the normal operation of the equipment. In addition, the door cannot effectively prevent dust from entering the rack when not in use, and the lack of restrictions on the door's opening and closing position easily causes component damage and door deformation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vertical three-dimensional container double door combination system to solve the problems of unstable door drive, easy deviation, poor dust prevention effect and lack of effective limit in the prior art.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A vertical cargo container double-door combination system includes door structures that open and close vertically opposite each other. Each door structure has a drive mechanism and a guide mechanism located in its center.

[0006] The drive mechanism includes a drive motor, a transmission shaft, and a fixed base. The drive motor is fixed to the back of the door structure. The drive motor meshes with one end of the transmission shaft via a synchronous belt I. The other end of the transmission shaft is connected to a metal wheel inside the fixed base via a synchronous belt II. The fixed base is installed on the frame of the vertical three-dimensional container. The door structure opens and closes relative to the frame under the drive of the drive motor.

[0007] The guiding mechanism includes a guide rail and pulleys installed in the guide rail. The guide rail has a pre-drilled groove that matches the lifting rod of the frame. Pulleys are spaced apart on the inner wall of the groove and are installed close to the lifting rod.

[0008] This technical solution ensures relatively stable power transmission for large-sized doors by adding a drive mechanism with a synchronous belt II to the door structure. Furthermore, to prevent the large door structure from shifting during the opening and closing motion, a guide mechanism is added to the back of the door structure, and a pulley is added inside the guide mechanism. This guide mechanism does not affect the opening and closing motion, making the opening and closing smoother.

[0009] In addition, the vertical three-dimensional container double-door combination system proposed above according to this utility model may also have the following additional technical features:

[0010] According to one embodiment of the present invention, the guide mechanism is symmetrically arranged along the drive mechanism, and the guide mechanism includes at least two sets of guide rails located on the side of the drive motor.

[0011] In this technical solution, at least two sets of guide structures on the left and right sides are used to guide the door mechanism with pulleys on both sides, so that the force is more even during the opening and closing process, avoiding uneven force distribution caused by guidance on only one side, which would affect the life of the guide mechanism.

[0012] According to one embodiment of the present invention, the door structure includes an upper door and a lower door. The upper door and the lower door are closed relative to each other, preventing dust from entering the vertical storage container. When the upper door and the lower door are open relative to each other, goods enter the vertical storage container through the door structure.

[0013] In this technical solution, the purpose of the door structure is to close when goods are not stored, preventing dust from entering the vertical storage container. Therefore, the door structure needs to be closed when not in operation, and opened promptly when in operation.

[0014] According to one embodiment of the present invention, limit switches are also provided at the top of the upper door and the bottom of the lower door, and the limit switches are used to detect the positions of the top of the upper door and the bottom of the lower door.

[0015] In this technical solution, if the upper door is lifted indefinitely, it will cause excessive stress on the synchronous belt II, affecting the life of the synchronous belt II. At the same time, it also prevents the top of the upper door from hitting the fixed seat above. Therefore, the limit switch can ensure that the upper door has an appropriate lifting distance.

[0016] According to one embodiment of the present invention, the lower door body is further provided with a limiting mechanism, which includes a limiting vertical shaft and a limiting seat. The bottom end of the limiting vertical shaft is installed on the ground by a fixing member, and the top end of the limiting vertical shaft passes through the limiting seat. The limiting seat is fixed to the back of the lower door body.

[0017] In this technical solution, since the lower door falls to the ground due to gravity, it is in frequent contact with the ground and is more prone to deformation than the upper door. In order to prevent the lower door from shifting, in addition to the guide mechanism, an additional limiting mechanism is required.

[0018] According to one embodiment of the present invention, the limiting mechanism is disposed on both sides of the drive motor of the lower door body.

[0019] In this technical solution, the limiting mechanisms are also set in pairs on the lower door body, with a set of limiting mechanisms set on both sides of the lower door body in conjunction with the ground.

[0020] According to one embodiment of the present invention, the limiting vertical shaft is provided with at least one limiting seat through it.

[0021] In this technical solution, the limiting seats can be spaced out on the back of the lower door body to save costs and use small-sized limiting seats to limit the same limiting vertical shaft.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] (1) By adding a drive mechanism with synchronous belt II to the door structure, the drive power transmission of large-size doors is ensured to be stable; at the same time, a guide mechanism with pulleys is added to the back of the door to prevent the door from shifting when opening and closing. The guide mechanism does not affect the movement while guiding, making the opening and closing smoother, the force more uniform, and extending the service life of the guide mechanism.

[0024] (2) The door structure consists of an upper door and a lower door. When not in use, the door is closed to prevent dust from entering the vertical three-dimensional container. The upper door is equipped with a limit switch at the top to prevent excessive lifting from damaging the synchronous belt II and impacting the fixed seat. The lower door is equipped with a limit mechanism to prevent it from shifting or deforming due to frequent contact with the ground caused by gravity. Attached Figure Description

[0028] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a vertical three-dimensional container double-door combination system, including door structures that open and close vertically relative to each other. Each door structure has a drive mechanism and a guide mechanism in its center.

[0031] The drive mechanism includes a drive motor 2, a transmission shaft 3, and a fixed base 4. The drive motor 2 is fixed to the back of the door structure. The drive motor 2 is engaged with one end of the transmission shaft 3 via a synchronous belt I 5. The other end of the transmission shaft 3 is connected to a metal wheel inside the fixed base 4 via a synchronous belt II 6. The fixed base 4 is installed on the frame of the vertical three-dimensional container. The door structure opens and closes relative to the frame under the drive of the drive motor 2.

[0032] The guiding mechanism includes a guide rail 7 and pulleys 8 installed in the guide rail 7. The guide rail 7 has a slot for cooperating with the lifting rod of the frame. The pulleys 8 are spaced apart on the inner wall of the slot and are closely attached to the lifting rod.

[0033] like Figure 1 and Figure 2 As shown, this technical solution ensures relatively stable power transmission for large-sized door drives by adding a drive mechanism with a synchronous belt II6 to the door structure; and to prevent the large door structure from shifting during the up-and-down opening and closing motion, a guide mechanism is added to the back of the door structure, and a pulley 8 is added inside the guide mechanism, which guides without affecting the up-and-down opening and closing motion, making the opening and closing smoother.

[0034] In addition, the vertical three-dimensional container double-door combination system proposed above according to this utility model may also have the following additional technical features:

[0035] According to one embodiment of the present invention, the guide mechanism is symmetrically arranged along the drive mechanism, and the guide mechanism includes at least two sets of guide rails 7 located on the side of the drive motor 2.

[0036] In this technical solution, at least two sets of guide structures on the left and right sides are used to guide the door mechanism with pulleys 8 on both sides, so that the force is more even during the opening and closing process, avoiding uneven force due to guidance on only one side, which would affect the life of the guide mechanism.

[0037] According to one embodiment of the present invention, the door structure includes an upper door 1 and a lower door 9. The upper door 1 and the lower door 9 are closed relative to each other, preventing dust from entering the vertical storage container. When the upper door 1 and the lower door 9 are open relative to each other, goods enter the vertical storage container through the door structure.

[0038] In this technical solution, the purpose of the door structure is to close when goods are not stored, preventing dust from entering the vertical storage container. Therefore, the door structure needs to be closed when not in operation, and opened promptly when in operation.

[0039] According to one embodiment of the present invention, limit switches are also provided at the top of the upper door body 1 and the bottom of the lower door body. The limit switches are used to detect the positions of the top of the upper door body 1 and the bottom of the lower door body.

[0040] In this technical solution, if the upper door body 1 is lifted indefinitely, it will cause excessive force on the synchronous belt II 6, affecting the life of the synchronous belt II 6. At the same time, it also prevents the top of the upper door body 1 from hitting the upper fixed seat 4. Therefore, the limit switch can ensure that the upper door body 1 has an appropriate lifting distance.

[0041] According to one embodiment of the present invention, the lower door body 9 is further provided with a limiting mechanism, which includes a limiting vertical shaft 10 and a limiting seat 11. The bottom end of the limiting vertical shaft 10 is installed on the ground by a fixing member, and the top end of the limiting vertical shaft 10 is provided through the limiting seat 11. The limiting seat 11 is fixed to the back of the lower door body 9.

[0042] In this technical solution, since the lower door 9 falls to the bottom due to gravity and lands on the ground, it is in frequent contact with the ground and is more prone to deformation than the upper door 1. In order to prevent the lower door 9 from shifting, in addition to the guide mechanism, an additional limiting mechanism is required.

[0043] According to one embodiment of the present invention, the limiting mechanism is disposed on both sides of the drive motor 2 of the lower door body 9.

[0044] In this technical solution, the limiting mechanisms are also set in pairs on the lower door body 9, and a set of limiting mechanisms is set on both sides of the lower door body 9 in conjunction with the ground.

[0045] According to one embodiment of the present invention, the limiting vertical shaft 10 is provided with at least one limiting seat 11 through it.

[0046] In this technical solution, the limiting seat 11 can be spaced out on the back of the lower door body 9 to save costs, and the small-sized limiting seat 11 can be used to limit the same limiting vertical shaft 10.

[0047] The usage process of the above embodiments is as follows: Figure 1 and Figure 2As shown, when not in operation, the upper door 1 and lower door 9 are closed relative to each other, sealing the container and preventing dust from entering. At this time, the drive motor 2 is not working, and the door structure remains stationary. When goods need to be stored or retrieved, the drive motor 2 starts, driving the transmission shaft 3 to rotate via the synchronous belt I5. The synchronous belt II6 at the other end of the transmission shaft 3 moves accordingly, thereby driving the metal wheel in the fixed seat 4 to rotate, causing the door structure to open and close relative to the frame. During this process, the pulley 8 in the guide rail 7 of the guide mechanism is in close contact with the lifting rod of the frame, playing a guiding role when the door opens and closes, ensuring smooth opening and closing of the door without deviation. At the same time, due to at least two sets of guide structures on the left and right, the force during opening and closing is even. When the upper door 1 is lifted, the limit switch detects its top position. When the upper door 1 reaches an appropriate lifting distance, the limit switch takes effect, preventing the upper door 1 from being lifted indefinitely, avoiding excessive force on the synchronous belt II6 and collision with the fixed seat 4 above. When the lower door 9 falls to the bottom due to gravity, the limiting vertical shaft 10 of the limiting mechanism cooperates with the limiting seat 11 to restrict the position of the lower door 9, prevent it from shifting or deforming due to frequent contact with the ground, and ensure the stable operation of the lower door 9.

[0048] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
