Description

Technical Field

[0001] This utility model relates to the field of elevator hook technology, specifically to a reusable and portable elevator hook device for use on H-shaped steel beams. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for transporting people or goods in multi-story buildings. Elevator installation requires a hook to lift the main unit. Currently, existing technology for installing elevator hook devices in steel structure buildings mainly involves either fabricating the hook simultaneously with the main structural components at a steel component processing plant and installing it on the steel beams, or pre-embedding the elevator hook components in the reinforced concrete floor slab after fabrication. Both methods permanently fix the elevator hook to the main structure. However, as is well known, the utilization frequency of elevator hook devices in actual engineering applications is extremely low, only a few times during elevator installation and commissioning, and subsequent maintenance and repair. This leads to traditional installation methods that waste steel and labor, negatively impacting project economic efficiency and presenting problems. Utility Model Content

[0005] Preferably, the shackle is U-shaped, with two adapter plates located inside the shackle, and a gasket of the same thickness as the hook claw sandwiched between the two adapter plates, the gasket being rotatably connected to the cross pin.

[0006] Preferably, the working surface of the hook body is provided with flat teeth, and the working surface of the hook claw is provided with arc teeth.

[0007] Preferably, an H-shaped steel beam is held between the working surfaces of the hook body and the hook claw.

[0008] The beneficial effects of this utility model are: it is easier and more convenient to install and use, it can be reused repeatedly, it shortens the processing period, saves materials, and saves costs. Attached Figure Description

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. 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.

[0016] 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.

[0017] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.

[0018] 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.

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific implementation of this utility model will be described in detail below with reference to specific embodiments: such as Figures 1-4 The present invention is achieved through the following technical solution: This embodiment is a reusable and portable elevator hook device for H-shaped steel beams. The nodes include: hook body 1 and hook claw 2 are connected by pins 3. The hook claw 2 is inserted into the hook body 1 and can rotate flexibly around the pins 3. Flat teeth are provided on the working surface of the hook body 1, and arc teeth are provided on the working surface of the hook claw 2. A connecting hole is opened at the other end of the hook claw 2 and connected to the adapter plate 4 by pins 3. The adapter plate 4 can also rotate flexibly around the pins 3. This forms the left half of the device. The right half of the device is symmetrically arranged with the left half. The shackle 6 is U-shaped. The horizontal pin 7 of the shackle 6 passes through the two adapter plates 4. The two adapter plates 4 are located inside the shackle 6. A gasket 5 of the same thickness as the hook claw 2 is provided between the two adapter plates 4 so that the two hook bodies 1 and the hook claw 2 are on the same plane.

[0020] After the device is assembled, the hook body 1 and hook claw 2 can be installed and fixed on the lower flange of the H-beam 8. The elevator installation component can be suspended by the shackle 6. The weight of the installation component pulls down the shackle 6, which in turn pulls down the adapter plate 4. The adapter plate 4 pulls down the hook claw 2 so that the hook claw 2 and the hook body 1 clamp the H-beam 8.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
