Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an anti-slip structure for a cage door wheel frame. Background Art

[0002] At present, construction elevators are indispensable transportation equipment in most construction projects. The cage is generally a closed structure welded by steel sections, steel plates, and mesh plates. The front side of the cage is an open structure and is provided with a cage door. The two sides of the bottom of the cage door are respectively extended outward with L-shaped curved plates. The end of the curved plate away from the cage door extends to the rear side of the cage. The end of the curved plate is connected to the lifting wire rope, and the cage door is driven up and down by the lifting wire rope. The rear side of the curved plate close to the cage door is connected to a rotating shaft, and a door wheel is mounted on the rotating shaft. The middle part of the door wheel is provided with a limiting groove along the annular direction. The two sides of the cage door frame are respectively slidably connected to the limiting groove of the door wheel. The lifting and lowering of the cage door is limited forward and backward through the limiting groove. When construction workers enter the structural floor from the cage to transport materials, there is a situation of hitting the cage door, which may cause damage to the door wheel part and the cage door is at risk of detaching from the cage door frame. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problem, thereby providing a cage door wheel frame anti-slip structure which can enhance the safety protection of the cage door.

[0004] The utility model solves the above problems and adopts the following technical solutions:

[0005] A cage door wheel frame anti-detachment structure comprises a cage door frame and an outer cage door, door hook bent plates are horizontally fixed on both sides of the bottom of the outer side surface of the cage door, the middle part of the door hook bent plate is bent and extends toward the rear side of the cage door frame, the door hook bent plate is rotatably connected with a rotating shaft in the middle part close to the cage door side, the inner end of the rotating shaft extends toward the inside of the cage and is fitted with a door wheel, a limiting groove is annularly arranged in the middle part of the door wheel, both sides of the cage door frame are respectively slidably engaged in the limiting grooves of the door wheel, and baffle mechanisms parallel to the door wheel are arranged on both sides of the bottom of the inner side surface of the cage door.

[0006] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0007] The door wheel part on the inner side of the cage door is shielded by the baffle mechanism. When construction workers transport materials and hit the cage door, even if the door wheel is damaged, the baffle mechanism can prevent the cage door from detaching from the cage door frame and causing people and goods to fall from a high altitude, thereby ensuring the safety of construction workers.

[0008] As a preferred embodiment, a further technical solution of the utility model is:

[0009] Further, the baffle mechanism includes limiting plates fixed on both sides of the bottom of the inner side of the cage door. One end of the rotating shaft away from the door hook bent plate penetrates through the limiting plate and is rotatably connected to the limiting plate. Description of the Drawings

[0014] The following further describes the present utility model in conjunction with embodiments. The purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0015] A cage door wheel frame anti - detachment structure includes a cage door frame 1 and a cage door 2 on the outside. On both sides of the bottom of the outer side of the cage door 2, door hook bent plates 3 are horizontally fixed. The door hook bent plates 3 extend away from the cage door 2 side. The middle of the door hook bent plate 3 is bent and extends towards the rear side of the cage door 2 frame. The outer end of the door hook bent plate 3 is connected to the lifting steel wire rope. The middle of the door hook bent plate 3 close to the cage door 2 side is rotatably connected to a rotating shaft 5. The rotating shaft 5 is perpendicular to the cage door 2. The inner end of the rotating shaft 5 extends towards the inside of the cage and is sleeved with a door wheel 4. A limiting groove is circumferentially arranged in the middle of the door wheel 4. Both sides of the cage door frame 1 are respectively slidably clamped in the limiting groove of the door wheel 4. On both sides of the bottom of the inner side of the cage door 2, a baffle mechanism parallel to the door wheel 4 is arranged. The cage door 2 is limited by the baffle mechanism to prevent the cage door 2 from detaching from the cage door frame 1 when the door wheel 4 is damaged.

[0016] Further, the baffle mechanism includes limiting plates 6 fixed on both sides of the bottom of the inner side of the cage door 2. One end of the rotating shaft 5 away from the door hook bent plate 3 penetrates through the limiting plate 6 and is rotatably connected to the limiting plate 6. When the cage door 2 is impacted, the limiting plate 6 limits the cage door 2.

[0017] The limiting plate 6 shields and limits the door wheel part on the inner side of the cage door 2. When the construction workers transport materials and impact the cage door 2, even if the door wheel 4 is damaged, the cage door 2 can be limited by the limiting plate 6, avoiding the cage door 2 detaching from the cage door frame 1 and causing people and goods to fall from a height, ensuring the safety of construction workers.

[0018] The above are only the preferred and feasible embodiments of the present utility model, and thus do not limit the scope of rights of the present utility model. Any equivalent changes made by using the content of the specification and drawings of the present utility model are included within the scope of rights of the present utility model.
