Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an interchangeable structure of large and small flap doors of an elevator cage. Background Art

[0002] With the rapid development of modern construction industry, high-rise and super high-rise buildings are increasing day by day, and vertical lifting machinery for transporting construction personnel and building materials has been developed and applied in large quantities. Practice has proved that construction elevators that undertake vertical transportation of personnel and materials in high-rise building construction can save man-hours and improve labor productivity.

[0003] Since the guide rail frame of the construction elevator is attached to the outside of the building structure, there is a distance between the construction elevator and the outer edge of the building structure. Therefore, during the construction process, it is necessary to build construction passages for transporting personnel and materials between the construction elevator and the outer edge of the building structure, which consumes a lot of manpower and material resources and reduces construction efficiency.

[0004] According to the distance between the elevator cage and the construction platform, the flap doors used on the cage are divided into large flap doors of about 1m or small flap doors of about 0.5m. The flap doors are overlapped to the construction platform by at least 200mm to avoid potential safety hazards. When the large flap doors are used, an upper protective door that slides up and down is provided on the upper part of the cage entrance and exit. When the hinged large flap doors are closed, they serve as the lower protective doors of the cage entrance and exit and are located on the outside of the cage entrance and exit, opposite to the upper protective door up and down. When the small flap doors are used, the length of the small flap doors cannot completely cover the lower part. The cage is protected by a barrier, so when closed, the upper and lower parts of the cage entrance and exit are respectively slidably provided with upper protective doors and lower protective doors, and the small flap door is turned to an upright state and located inside the cage; the hinge point between the large flap door and the cage is closer to one side of the cage entrance and exit than the junction between the small flap door and the cage. When the construction site is completed and moved to the next construction site, it is necessary to re-measure the distance between the cage and the building platform to ensure the use of the large flap door or the small flap door. Cages of different sizes need to be prepared, which increases the project cost. Utility Model Content

[0005] The utility model aims to solve the above-mentioned problem, thereby providing a lift cage large and small flap door interchange structure which can reduce the construction cost.

[0006] The utility model solves the above problems and adopts the following technical solutions:

[0007] A structure for interchangeable large and small flap doors of an elevator cage comprises a cage, an inlet and outlet are arranged on one side of the cage, a foot pedal is arranged at the top of the bottom surface inside the cage, hinged ears are fixed at intervals on the side of the foot pedal opposite to the inlet and outlet, the distance between the side of the foot pedal provided with the hinged ear and the cage inlet and outlet is adjustable, and a flap door is hinged on the hinged ear of the foot pedal.

[0008] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0009] By adjusting the distance between the foot pedal and the cage entrance and exit, different flap doors can be selected according to the different distances between the cage and the building platform. When the distance is small and a small flap door is selected, the foot pedal is adjusted so that the hinged ear is located inside the cage, so that the small flap door is located on the inside of the cage and close to the upper and lower protective doors when it is turned to an upright state. When the distance is large and a large flap door is selected, the foot pedal is adjusted so that the hinged ear is located at the edge of the cage, so that the large flap door is located on the outside of the cage entrance and exit when it is turned to an upright state as the lower protective door, opposite to the upper protective door above and below. It can be suitable for different working conditions and reduces the project cost.

[0010] As a preferred embodiment, a further technical solution of the utility model is:

[0011] Furthermore, the foot pedal includes a relative main board and a connecting strip, the main board is fixed on the inner side of the top of the bottom surface of the cage, and the connecting strip is located on the outer side of the top of the bottom surface of the cage. The main board and the connecting strip are detachably connected by bolts. First hinged ears are arranged at intervals on the side of the main board close to the inlet and outlet, and a plurality of accommodating grooves opposite to the first hinged ears are provided on the side of the connecting strip opposite to the main board, and second hinged ears are arranged at intervals on the side of the connecting strip close to the inlet and outlet.

[0012] Furthermore, the main board and the connecting bar have equal thickness and width. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0020] A structure for interchangeable large and small flap doors of an elevator cage comprises a cage 1, an inlet and an outlet are arranged on one side of the cage 1, a foot pedal is arranged inside the cage 1 and at the top of the bottom surface, hinged ears are fixed at intervals on the side of the foot pedal opposite to the inlet and outlet, the distance between the side of the foot pedal provided with the hinged ear and the inlet and outlet of the cage 1 is adjustable, a flap is hinged on the hinged ear of the foot pedal, the foot pedal is adjusted according to the distance between the cage and the building platform, and then the position of the hinged ear is adjusted, so as to be suitable for different working conditions.

[0021] Furthermore, the foot pedal includes a relative main board 2 and a connecting strip 3. The main board 1 is fixed on the inner side of the top of the bottom surface of the cage 1, and the connecting strip 3 is located on the outer side of the top of the bottom surface of the cage 1. The main board 2 and the connecting strip 3 are detachably connected by bolts. The side of the main board 1 close to the inlet and outlet is provided with first hinged ears 4 at intervals. The side of the connecting strip 3 opposite to the main board 2 is provided with a plurality of accommodating grooves 5 opposite to the first hinged ears 4. The side of the connecting strip 3 close to the inlet and outlet is provided with second hinged ears 6 at intervals. The second hinged ears 6 are located at the edge of the inlet and outlet of the cage 1. Different flap door sizes are selected according to the spacing between the cage 1 and the building platform to determine whether the connecting strip needs to be connected. When the large flap door 7 is used, the large flap door 7 is hinged to the second hinged ear 5 of the connecting strip 3. When the small flap door 8 is used, the connecting strip 3 is removed and the small flap door 8 is hinged to the first hinged ear 4.
