Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and more specifically, to a cage door of a construction elevator. Background Art

[0002] Construction hoists are a type of construction machinery that is often used in construction projects to carry people and goods. They are also called construction elevators or construction hoists. This type of equipment is mainly used to transport pedestrians or building materials vertically, and is particularly suitable for high-rise and super-high-rise buildings in cities. Since such building heights are difficult to complete with a crisscross frame or gantry, construction hoists have become an indispensable tool.

[0003] The elevator mainly uses a cage (hereinafter referred to as the elevator cargo compartment) to load people and goods, and is driven by the elevator driving mechanism for lifting and lowering. The elevator cargo compartment is equipped with a cage door for the entry and exit of people and goods, and each floor of the building is equipped with a floor door for use with the cage door.

[0004] At present, the closing of the protective door during the operation of the elevator is only sensed by one sensor. However, if there are goods or people under the door during the closing process of the protective door, the door will continue to close until the sensor is triggered, thus affecting the safety of use.

[0005] The applicant applied for a protective door for an elevator with the publication number: CN219362939U on 2023-01-18. By setting an anti-collision strip at the bottom of the protective door, the safety of the protective door during closing can be improved. However, there are still some other safety hazards for the protective door. For example, when the elevator loses control, the protective door is at risk of crashing out of the cage. Utility Model Content

[0006] The main purpose of the utility model is to provide an elevator cage door, aiming to solve the problem that the existing cage door is easy to separate from the cage.

[0007] In order to solve the above technical problems, the utility model proposes an elevator cage door, the elevator comprising: a cage, wherein the cage door comprises:

[0034] An elevator cage door of the present application is described in detail through the following embodiments.

[0035] Embodiment 1:

[0036] In this embodiment, the elevator includes: a cage and a cage door installed on the cage. The cage door is mainly assembled on the cage in a sliding manner, and the lifting and lowering of the cage door is controlled by an electric control device to realize the opening and closing of the cage.

[0037] During the operation of the elevator, it was found that the cage door was installed in a vertical sliding manner. Therefore, when a serious electrical control failure occurred in the elevator, the cage door would detach from the cage. Specifically, the cage door would be knocked outward, which could easily cause injuries to the workers in the cage.

[0038] In view of this safety hazard, the cage door on the cage is now reinforced, as follows.

[0039] like Figure 1-Figure 4 As shown, the cage door includes:

[0040] The cage door body 100 is slidably disposed on the cage in a vertical direction for opening or closing the cage; the anti-collision portion 200 is disposed on the cage door body 100 for limiting the cage door body 100 from departing from the sliding track on the cage;

[0041] Among them, the anti-collision part 200 includes: an anti-collision beam 210, which is arranged on the cage door body 100; and a limit block 220, which is arranged in the cage; when at least one end of the anti-collision beam 210 is located on the limit block 220, the anti-collision beam 210 is limited, and the limiting direction of the anti-collision beam 210 does not include its sliding direction.

[0042] In the present technical solution, when the elevator is ascending or descending, the cage door is closed on the cage. In order to prevent the cage door from being knocked out of the cage, an anti-collision part 200 is provided, wherein an anti-collision beam 210 is installed on the cage door, and a limit block 220 is installed in the cage. The limit block 220 limits the anti-collision beam 210 to prevent the cage door from detaching from the cage. In this way, the safety hazard of the cage door detaching can be solved. Although the structure is relatively simple, it is highly practical and can effectively avoid the occurrence of such accidents.

[0043] Embodiment 2:

[0044] This embodiment is a further improvement made on the basis of the first embodiment.

[0045] like Figure 1-Figure 4 As shown, in the present embodiment, there is a risk of unhooking when the cage door is only closed. For this purpose, the anti-collision beam 210 can be set at the bottom of the cage door, and the limit block 220 can be installed on the lower side of the cage. During the closing process of the cage door, the cage door gradually slides downward, and the anti-collision beam 210 thereon also gradually slides toward the limit block 220. When the cage door is completely closed, the end of the anti-collision beam 210 also moves into the limit block 220 and is limited by the limit block 220.

[0046] The above-mentioned installation method is used to facilitate the installation of some other structures under the cage door.

[0047] Embodiment three:

[0048] This embodiment is a further improvement made on the basis of the second embodiment.

[0049] like Figure 2 and Figure 3 As shown, in this embodiment, the limit block 220 has a U-shaped structure. When the anti-collision beam 210 slides synchronously with the cage door body 100, the end of the anti-collision beam 210 slides in the groove of the limit block 220, or can slide in and out of the groove of the limit block 220.

[0050] In this technical solution, a clamping limiter is used to achieve that when the cage door is fully closed, it is clamped on the cage. This design not only improves the installation strength between the cage door and the cage, but also does not affect the lifting and lowering of the cage door.

[0051] Optimally, there are two limit blocks 220, which are respectively arranged below the two sides of the cage. By setting two limit blocks 220, the limiting ability of the limit blocks 220 acting on the anti-collision beam 210 is improved.

[0052] Embodiment 4:

[0053] This embodiment is a further improvement made on the basis of the second and third embodiments.

[0054] like Figure 2 and Figure 3 As shown, in the present embodiment, the anti-collision beam 210 is made of a square steel pipe, on which a connecting pipe 230 is welded, and a connecting plate 240 is welded on the connecting pipe 230. The connecting plate 240 can be installed on the lower side of the cage door body 100 by bolt connection to facilitate subsequent disassembly and assembly. Of course, the connecting plate 240 can also be directly welded to the cage door body 100 by welding.

[0055] The connecting pipe 230 is also a square steel pipe, and the connecting plate 240 is an L-shaped steel plate, the side of which is welded to the connecting pipe 230, and a hole 241 is opened on the upper end surface for bolts to pass through. The connecting plate 240 is fixed to the cage door body 100 by bolts.

[0056] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
