Description

Technical Field

[0001] The utility model relates to an electric door for a hanging cage, in particular to an electric door for a hanging cage which saves installation space. Background Art

[0002] As a key component of the construction elevator, the cage is driven by a motor to move up and down along the guide frame, thereby realizing the function of the construction elevator to transport people and goods. Due to the continuous development and progress of electronic control technology and automation technology, some construction elevator cages have been manufactured with cage doors that can open and close automatically. The cage doors of most construction elevator cages with automatic opening and closing can move up and down, and the motor drives the chain to rotate, thereby driving the cage door behind the chain to move up and down.

[0003] For the convenience of installation and maintenance, the existing motors and linkage structures are all installed on the top of the cage. Although they can cooperate with the chain, the motor installed on the top of the cage not only occupies the position of the cage top, hindering the workers' walking and taking up the space on the cage top, but also the external motor and linkage structure in the operating structure of the cage. If they are hit by falling objects from the cage top, it is very easy to cause the motor to fail, thereby causing the cage door to fail to open and close normally.

[0004] Therefore, this case aims to provide an electric door for a cage that saves installation space, and can install the motor for opening and closing the cage door inside the cage, and can normally drive the chain on the side of the door frame to rotate, thereby achieving the effect of having a built-in motor without affecting the normal movement of the cage door. Utility Model Content

[0005] The utility model provides an electric door for a cage which saves installation space and can effectively solve the above problems.

[0006] The utility model is achieved in this way:

[0007] An electric door for a cage that saves installation space is movably installed on a cage door frame, comprising: a door panel movably connected to the cage door frame, chains are arranged on both sides of the cage door frame, the cage door frame is fixedly connected to both sides of a cage car, and the electric door for the cage also includes:

[0008] A built-in driving structure, with two mounting holes on both sides of the cage door frame. The built-in driving structure includes a fixed frame arranged on the inner side of the cage car, a driving structure is locked on the fixed frame, a guide member is arranged in the mounting hole, both ends of the driving structure are fixedly connected with matching members, a gear is arranged at the end of the matching member away from the driving structure, and the gear is meshed with a chain. When the built-in driving structure rotates, the driving structure drives the matching member to rotate, and the gear connected to the matching member drives the chain to rotate.

[0009] As a further improvement, the driving structure includes a top mounting seat arranged on the top of the inner side of the cage door frame, the lower end of the top mounting seat is connected to two mounting plates, the bottom of the mounting plate is locked with a driving unit, and the right half of the driving unit is locked to the inner side of the fixed frame.

[0010] As a further improvement, the fixed frame includes an L-shaped connecting plate supporting the driving unit, a closing plate is connected to the side of the L-shaped connecting plate, and a connecting rod connected to the main cage body of the cage car is connected to the rear end of the L-shaped connecting plate.

[0011] As a further improvement, the guide member includes a connecting seat locked on the inner wall of the cage door frame, a rotating bearing is arranged on the inner side of the connecting seat, and the matching member passes through the rotating bearing.

[0012] As a further improvement, the matching piece includes a rotating rod meshed with the driving unit, and a protective rod is sleeved on the outside of the rotating rod.

[0013] The beneficial effects of the utility model are:

[0014] In the existing settings of electric cage doors, especially in the settings of upper and lower sliding doors, a driving structure is mostly set on the top of the car to drive the cage door to slide up and down. However, this sliding method not only occupies the position on the top of the car, which is inconvenient for repair and maintenance, but also easily causes damage to the driving structure. Therefore, the utility model adds a built-in driving structure, and sets the entire driving structure to the interior of the cage car through a fixed frame, so that the inner driving gear is realized under the drive of the guide part and the matching part, so that the gear and the chain of the cage door are matched, thereby avoiding the inconvenience and unsafety of setting the driving structure in the space on the top of the car.

[0015] Although the driving structure is installed inside the entire car, the deformation of the car top will still affect the normal operation of the driving structure when it is hit by heavy objects. Therefore, in this case, a top mounting seat and a mounting plate are set in the driving structure to form a wrap-like protection for the driving unit. Even if the driving structure is squeezed by foreign objects, it is the top mounting seat and the mounting plate that are deformed, thereby reducing the impact of foreign objects on the driving unit and allowing the cage door to open and close normally.

[0016] During the process of setting the top mounting seat and the mounting plate, the top mounting seat and the mounting plate can form a wrapping structure with the fixing frame, so that the entire driving structure is contained in a protective space, so that even if the car is greatly deformed, it is not easy to affect the normal operation of the driving unit, so that the door can be opened normally to escape when an unexpected situation occurs.

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0025] Referring to Figure 1 to Figure 5 As shown, an electric door for a cage that saves installation space is movably installed on a cage door frame 10, and includes: a door panel 20 movably connected to the cage door frame 10. Chains 30 are arranged on both sides of the cage door frame 10. The cage door frame 10 is fixedly connected to both sides of a cage car 40. The electric door for the cage further includes: an in-built driving structure 50. Two mounting holes are provided on both sides of the cage door frame 10. The in-built driving structure 50 includes a fixing frame 51 arranged inside the cage car 40. A driving structure 52 is locked to the fixing frame 51. Guide members 53 are arranged in the mounting holes. Both ends of the driving structure 52 are fixedly connected with fitting members 54. A gear 55 is arranged at one end of the fitting member 54 away from the driving structure 52. The gear 55 meshes with the chain 30. When the in-built driving structure 52 rotates, the driving structure 52 drives the fitting member 54 to rotate, and the gear 55 connected to the fitting member 54 drives the chain 30 to rotate.

[0026] In this embodiment, in order to move the door panel 20 up and down evenly, two groups of chains 30 are provided. The two groups of chains 30 are arranged symmetrically and cooperate with the two gears 55, so as to provide power at both ends.

[0027] In the setting of the existing cage electric door, especially in the setting of the upper and lower sliding doors, it is mostly adopted to drive the cage door to slide up and down by setting a driving structure on the top of the car. However, adopting this sliding method not only occupies the position on the car top, is not convenient for maintenance, but also easily causes damage to the driving structure. Therefore, in the present utility model, through the added in-built driving structure 50, the whole driving structure 52 is arranged inside the cage car 40 through the fixing frame 51, so as to drive the inner driving gear 55 under the drive of the guide member 53 and the fitting member 54, and make the gear 55 cooperate with the chain 30 of the cage door, thus avoiding the inconvenience and insecurity of setting the driving structure 52 in the car top space.

[0028] Although the driving structure 52 is set inside the entire car, when the car roof is hit by a heavy object, the deformation of the car roof will still affect the normal operation of the driving structure 52. Therefore, the driving structure 52 of this embodiment includes a top mounting seat 522 arranged on the top of the inner side of the cage door frame 10, and the lower end of the top mounting seat 522 is connected to two mounting plates 521, and the bottom of the mounting plate 521 is locked with a driving unit 523, and the right half of the driving unit 523 is locked to the inner side of the fixed frame 51. By arranging the top mounting seat 522 and the mounting plate 521 in the driving structure 52, a wrapping protection is formed for the driving unit 523. Even if the driving structure 52 is squeezed by foreign objects, it is the top mounting seat 522 and the mounting plate 521 that are deformed, thereby reducing the influence of foreign objects on the driving unit 523 and allowing the cage door to open and close normally.

[0029] The driving unit 523 in this embodiment is not just a simple driving motor, but a combination of a driving motor and a reducer.

[0030] In order to form a closed-loop protection with the top mounting seat 522 and the mounting plate 521, the fixed frame 51 includes an L-shaped connecting plate 511 supporting the driving unit 523, and the L-shaped connecting plate 511 is connected to a closing plate 512 on the side, and the rear end of the L-shaped connecting plate 511 is connected to a connecting rod 513 connected to the main cage body of the cage car 40, so that during the setting process of the top mounting seat 522 and the mounting plate 521, the top mounting seat 522 and the mounting plate 521 can form a wrapping structure with the fixed frame 51, so that the entire driving structure 52 can be accommodated in a protective space, so that even if the car is greatly deformed, it is not easy to affect the normal operation of the driving unit 523, so that the door can be opened normally to escape when an unexpected situation occurs.

[0031] In order to ensure the turnover accuracy of the fitting 54 during operation, in the present embodiment, a guide member 53 is used to guide its rotation trajectory. Specifically, the guide member 53 includes a connecting seat 531 locked on the inner wall of the cage door frame 10, and a rotating bearing 532 is provided on the inner side of the connecting seat 531. The fitting 54 passes through the rotating bearing 532, so that the rotation of the fitting 54 is limited within the rotating bearing 532.

[0032] Among them, the matching part 54 of this embodiment includes a rotating rod 541 meshing with the driving unit 523, and a protective rod 542 is sleeved on the outside of the rotating rod 541. The rotating rod 541 in a rotating state is protected by the protective rod 542 to prevent it from affecting the normal opening and closing of the door panel 20 when it is damaged. Among them, the protective rod 542 will be fixed by other sheet metal parts, which are not shown in this embodiment.

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
