Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, and in particular to a cage door linkage device for construction hoists. Background Technology

[0002] Construction hoists, also known as building construction elevators, outdoor elevators, or construction site hoisting cages, are widely used in the construction industry as transportation equipment for carrying people and goods. They are primarily used in high-rise and super high-rise buildings in cities, as the height of such buildings makes it extremely difficult to complete operations using scaffolding or gantry cranes. Construction hoists are frequently used personnel and goods transport machinery in construction, mainly for the interior and exterior decoration of high-rise buildings, bridges, chimneys, and other construction projects.

[0003] Traditional construction hoists require manual opening and closing of both the landing doors and the cage doors. However, during operation, the doors often fail to open properly, leading to accidental openings, safety hazards, and serious disruption to the normal operation of the construction hoist. Utility Model Content

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this utility model are as follows: In the actual use of the construction hoist, the door frame can be installed on the cage. When the construction hoist is in a closed state, the magnetic suction component is in operation. At the same time, the magnetic suction component drives the fixing block to be attracted to the lower part of the door frame, making the cage door assembly unable to open. When the cage reaches the designated position, the magnetic suction component stops running, making the cage door assembly in an active state. Then, the drive component is activated, causing the door extension plate to slide out.

[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 4 As shown, a cage door linkage device for a construction hoist of the present invention includes a door frame 1, a cage door assembly, an anti-misoperation assembly, and a linkage assembly. The cage door assembly is connected to the door frame 1. The lower part of the cage door assembly is detachably connected to the lower part of the door frame 1 through the anti-misoperation assembly. The linkage assembly is provided at the lower part of the cage door assembly.

[0028] The anti-accidental opening component includes a fixing block 11 and a magnetic suction component. The fixing block 11 is fixedly connected to the lower part of the cage door component, and the lower part of the fixing block 11 is detachably connected to the lower part of the door frame 1 through the magnetic suction component.

[0029] The linkage component includes a drive component and a cantilever plate 5. The cantilever plate 5 is slidably connected to the lower part of the cage door component, and the drive component is drivenly connected to the cantilever plate 5.

[0030] The working principle of this utility model is as follows: In the actual use of the construction hoist, the door frame 1 can be installed on the cage. When the construction hoist is in a closed state, the magnetic suction component is in operation. At the same time, the magnetic suction component drives the fixing block 11 to be attracted to the lower part of the door frame 1, so that the cage door assembly cannot be opened. When the cage reaches the designated position, the magnetic suction component stops running, so that the cage door assembly is in an active state. Then the drive component is run, so that the drive component drives the cantilever plate 5 to slide out. Then, while the cage door assembly is opened, the cantilever plate 5 is driven to lift the corresponding floor door of the cage.

[0031] Furthermore, the cage door assembly includes a lifting assembly, a first cage door 4, and a second cage door 3. A first sliding groove 6 is provided on one side of the interior of the door frame 1, and a second sliding groove 7 is provided on the other side of the interior of the door frame 1. The first cage door 4 is slidably connected to the first sliding groove 6, and the second cage door 3 is slidably connected to the first cage door 3. The lower part of the second cage door 3 is closed. The fixing blocks 11 are provided on both sides of the lower part of the first cage door 4. A sliding hole is provided at the lower part of the first cage door 4, and the door opening plate 5 is slidably connected to the sliding hole. The lifting assembly is installed on the upper part of the door frame 1, and the lifting assembly is drivenly connected to the first cage door 4.

[0032] As can be seen from the above description, when it is necessary to open the cage, the lifting assembly can be operated, so that the lifting assembly drives the first cage door 4 to slide and rise on the first slide rail 6. At the same time, the first cage door 4 lifts the second cage door 3 through the fixing block 11, so that the second cage door 3 slides and rises on the second slide rail 7, and the cage is opened.

[0033] Furthermore, a limiting block 10 is fixedly connected to the door panel 5, and the limiting block 10 is used to limit the movement range of the door panel 5.

[0034] As can be seen from the above description, this helps to prevent the cantilever panel 5 from detaching from the sliding hole.

[0035] Furthermore, the lifting assembly includes a mounting plate 9, a hoisting component 8, and a connecting component. The hoisting component 8 is mounted on the upper part of the door frame 1 via the mounting plate 9, and the hoisting component 8 is connected to the first cage door 4 via the connecting component.

[0036] As can be seen from the above description, when it is necessary to lift the first cage door 4, the lifting component 8 can be operated so that the lifting component 8 can lift the first cage door 4 through the connecting component.

[0037] Furthermore, it also includes a protective pad 12, which is provided on the upper part of the fixing block 11.

[0038] As can be seen from the above description, it is beneficial to protect the fixing block 11 and avoid damage to the fixing block 11 and the second cage door 3.

[0039] Furthermore, the driving assembly includes a rotating drive component and a drive wheel 13. The lower part of the door frame 1 is provided with a receiving groove. The rotating drive component is installed inside the receiving groove. The rotating drive component is drivenly connected to the drive wheel 13. The drive wheel 13 is located below the cantilever door panel 5. The side of the cantilever door panel 5 near the drive wheel 13 is provided with a toothed groove. The drive wheel 13 engages with the cantilever door panel 5 through the toothed groove.

[0040] As can be seen from the above description, when it is necessary to extend the door panel 5, the rotating drive component can be operated to drive the drive wheel 13 to rotate, and at the same time, the drive wheel 13 meshes with the tooth groove on the door panel 5 and drives the door panel 5 to extend.

[0041] Furthermore, it also includes mounting brackets 2, and several mounting brackets 2 are fixedly connected to the outside of the door frame 1.

[0042] As can be seen from the above description, it is advantageous for the door frame 1 to be installed onto the cage via the mounting bracket 2.

[0043] Furthermore, it also includes a controller, which is electrically connected to the cage door assembly, the anti-accidental opening assembly, and the linkage assembly, respectively.

[0044] As can be seen from the above description, it is beneficial to use the construction hoist to control the cage door assembly, the anti-misoperation assembly, and the linkage assembly through the controller, so that the cage can unlock and open the cage door after reaching the designated height.
