Description

Technical Field

[0001] This utility model belongs to the field of construction hoists, and in particular relates to a construction hoist installation and dismantling device. Background Technology

[0002] Construction hoists are crucial equipment for the vertical transportation of personnel and goods in modern construction, primarily consisting of guide rails, a cage, and a drive unit. Currently, the installation and dismantling of construction hoists in the air mostly rely on the electric boom integrated into the cage top. However, with the development of super high-rise buildings, to meet greater height and load-bearing requirements, hoists have adopted heavier and more specialized structural components such as reinforcing sections, vertical attachment sections, and swivel sections. The weight of these heavy structural components often exceeds the rated lifting capacity of the electric boom integrated into the cage top, making it impossible to safely and efficiently complete high-altitude installation and dismantling operations without the assistance of large external hoisting equipment. This severely restricts construction efficiency and introduces potential safety risks. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a construction hoist installation and dismantling device. This device is integrated into the hoist body and uses its own power to safely and reliably complete the installation and dismantling of heavy structural components at high altitudes without relying on external large hoisting equipment, thereby realizing the lowering and raising of the entire construction hoist.

[0004] The purpose of this utility model is achieved through the following technical measures: a construction hoist installation and dismantling device, comprising a support frame, a fixed beam, a movable arm, and an electric push rod. The support frame, serving as the load-bearing main body and mounting base of the entire device, adopts a modular design and is assembled from various support frame components using high-strength bolts. One bottom side of the support frame is connected to the construction hoist drive device via pins and bolts, and the other bottom side of the support frame is connected to the cage via connecting plates and bolts. The fixed beam is fixedly installed on the top of the support frame, providing a stable movement track for the movable arm. The movable arm is movably mounted on the track of the fixed beam via pulleys on it. An electric hoist is installed at the front end of the movable arm, enabling vertical lifting and positioning of structural components. The electric push rod, serving as a driving element, is hinged at one end to the front end of the movable arm and at the rear end of the fixed beam. By controlling the extension and retraction of the electric push rod, the movable arm can be driven to slide horizontally along the fixed beam, thereby performing the operation of pushing or pulling back structural components.

[0005] In the above technical solution, the main body of the fixed beam is made of I-beam profile, providing a stable movement track for the mobile arm. To ensure operational safety, stiffening plates are welded to the front and rear sections of the I-beam as mechanical stops to limit the travel of the mobile arm. Electrical limit switches are also installed at key positions in the rear section of the fixed beam. These electrical limit switches are interlocked with the elevator's control system. The logic is as follows: the elevator cage's operating circuit is only connected when the mobile arm is fully retracted and the electrical limit switch is triggered, allowing the cage to start normally. Once the mobile arm moves outward away from the "fully retracted" position, the electrical limit switch status changes immediately, cutting off the cage's operating circuit and preventing the cage from starting. Furthermore, double lugs are welded to the rear end of the fixed beam.

[0006] In the above technical solution, a limit stop plate is provided at the tail of the mobile arm, which triggers the electrical limit on the fixed beam when the mobile arm is in the "fully retracted" position. In addition, a double ear plate is provided at the front end of the mobile arm.

[0007] In the above technical solution, the front end of the electric push rod is hinged to the double ear plate at the front end of the moving arm via a pin, and the rear end of the electric push rod is hinged to the double ear plate at the tail end of the fixed beam via a pin.

[0008] Compared with the prior art, the construction hoist installation and dismantling device of this utility model has the following significant advantages:

[0009] 1. Self-contained system, no external equipment required: The installation and dismantling operations are carried out using the elevator's own power, eliminating the dependence on large external lifting equipment and reducing costs and site requirements.

[0010] 2. Strong load-bearing capacity: With a sturdy support frame and rigid transmission mechanism, it can safely handle the installation and dismantling of structural components such as heavy-duty reinforced sections and attachment sections.

[0011] 3. High safety: The unique dual protection mechanism of mechanical stop and electrical safety interlock ensures that the cage can never be started when the boom is not retracted, eliminating major safety hazards.

[0012] 4. Modular design: The support frame adopts a split modular structure, which is convenient for transportation and flexible on-site assembly, and has wide applicability.

[0013] 5. Intelligent operation, labor-saving and precise: Driven by electric push rods and electric hoists, the operation is smooth and the control is precise, realizing semi-automatic operation, which greatly reduces the labor intensity, skill requirements and high-altitude operation risks of operators.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 As shown, this embodiment provides a construction hoist installation and dismantling device, including a support frame 1, a fixed beam 2, a movable arm 3, and an electric push rod 4.

[0025] like Figure 2 and Figure 3As shown, the support frame 1, serving as the load-bearing main body and mounting base of the entire device, adopts a modular design. It is assembled from main frame 101, main frame 2 102, main frame 3 103, auxiliary frame 1 104, and auxiliary frame 2 105 using high-strength bolts 106. This design facilitates transportation and on-site installation. Main frame 101 is connected to the construction hoist drive device 5 via pins 107 and bolts 108, while main frame 2 102 is connected to the cage 6 via connecting plates 109 and bolts 110.

[0026] like Figure 1 and Figure 4 As shown, the fixed beam 2 is fixedly installed below the main frame 3 103 of the support frame 1. Its main body is made of I-beam 201 profile, providing a stable movement track for the moving arm 3. To ensure operational safety, stiffening plates 202 are welded to the front end and middle and rear sections of the I-beam 201 as mechanical stops to limit the movement stroke of the moving arm 3 and prevent derailment when it reaches extreme positions. Furthermore, an electrical limit switch 203 is installed at a critical position in the middle and rear section of the fixed beam 2. This electrical limit switch 203 is interlocked with the control system of the elevator. The logic is as follows: only when the moving arm 3 is fully retracted and the electrical limit switch 203 is triggered is the operating circuit of the elevator cage connected, allowing the cage 6 to start normally; once the moving arm 3 moves outward away from the "fully retracted" position, the state of the electrical limit switch 203 immediately changes, cutting off the operating circuit of the cage 6, preventing the cage 6 from starting. This fundamentally eliminates the risk of interference between the moving arm 3 and the guide rail frame 7 during installation and dismantling operations, ensuring absolute operational safety. In addition, a double ear plate 204 is welded to the tail end of the fixed beam 2.

[0027] like Figure 5 As shown, the movable arm 3 is movably mounted on the I-beam 201 track of the fixed beam 2 via pulleys 301. An electric hoist 302 is installed at the front end of the movable arm 3, enabling vertical lifting. A limit stop plate 303 is installed at the rear end, triggering the electrical limit stop 203 on the fixed beam 2 when the movable arm 3 is in the "fully retracted" position. Furthermore, a double-ear plate 304 is also provided at the front end of the movable arm 3.

[0028] like Figures 1 to 5 As shown, the electric push rod 4 serves as a driving element. Its front end is hinged to the double ear plate 303 at the front end of the moving arm 3 via a pin 8, and its rear end is hinged to the double ear plate 204 at the rear end of the fixed beam 2 via a pin 9. By controlling the extension and retraction of the electric push rod 4, the moving arm 3 can be precisely and smoothly driven to slide horizontally along the fixed beam 2, thereby performing pushing or pulling operations.

[0029] like Figure 6 and Figure 7As shown, when structural component 10 needs to be disassembled, the cage 6 is moved to the designated position, and the electric push rod 4 is started to drive the moving arm 3 to be horizontally pushed out towards the structural component 10 along the H-beam 201 track of the fixed beam 2 to the appropriate position. After the structural component 10 is disassembled, the electric hoist 302 is used to lift it vertically upward, and then the electric push rod 4 is driven to pull the moving arm 3 back. After the moving arm 3 is fully retracted, the electric hoist 302 is operated to place the lifted structural component 10 on top of the cage 6, and then the cage 6 is moved downward to the ground, thus completing the process of disassembling a structural component 10 from high altitude to transporting it to the ground.

[0030] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
