During the inspection or maintenance process, various lifting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position. During the installation of civil air defense projects, due to the small installation and construction space, general crane equipment cannot enter to perform lifting work, so the installation of civil air defense equipment uses a smaller and simpler lifting device for lifting.

[0023] Preferably, the method for operating the hoisting equipment for processing and installing the civil air defense door comprises the following steps:

[0024] Step 1: First, the electric lifting structure on the lifting device is used to make the height of the lifting device flush with the height of the installation site, and the electric lifting structure uses an electric lifting cylinder component to push the lifting column structure up and down to achieve height adjustment;

[0025] Step 2: After adjusting the height, use the hook component on the electric hoist assembly to hook the hook ring mechanism of the civil air defense door, and then drive the motor component to operate to make the rotating shaft in the noose assembly operate, and at the same time, reel in the double-strand steel cable. The reeling process is slow. When the double-strand steel cable is straightened, when the civil air defense door is lifted, stop driving the motor component, start the driving component, and make the two sets of electric hoist assemblies perpendicular to the two hook ring mechanisms to ensure the safety of the device during operation. After the adjustment is completed, the driving motor component continues to work, and the rotating shaft in the noose assembly is operated to achieve reeling, and finally the purpose of lifting the civil air defense door is achieved;

[0026] Step 3: According to the principle of convenient installation, the height of the fixed clamping structure is adjusted by adjusting the rod structure and the slide rail component. After the adjustment, the suspended civil air defense door is reversed by the driving motor component to release the noose assembly, so that the lower two corners of the civil air defense door are respectively placed in the clamping structure frame clamping grooves of the two sets of fixed clamping structures, and then the telescopic cylinder component pushes the telescopic rod to clamp the inserted civil air defense door, and then the driving motor component makes the double-strand steel cable tight;

[0027] Step 4: Finally, install it on the fixed civil air defense door according to the installation drawing until the installation is completed. After the final installation of the civil air defense door is completed, put it down and then load it onto a truck and transport it to the civil air defense installation site for installation.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention adopts the setting of an electric lifting structure. The main function of the electric lifting structure in the device of the present invention is to adjust the height of the lifting device itself. It can be adjusted according to the height limit of the installation site when the civil air defense door or other civil air defense equipment is installed, so as to achieve the optimal lifting height, which is beneficial to the subsequent installation of the civil air defense equipment.

[0030] 2. The connection plate installation base, the slide bar frame, the slide track component, the fixing bolt component, the drive component hook assembly, the connection ring component, the hook component, and the spring clamp assembly are arranged. The connection plate installation base is an installation and fixing base mechanism of the slide bar frame, which mainly plays the role of installation and fixing. The arrangement of the slide track component thereon is conducive to the use of the electric hoist assembly. In addition, the fixing bolt components installed at both ends of the slide track component are used to reinforce the connection of the slide track component.

[0031] The driving component on the electric hoist assembly utilizes the sliding track component on the slide bar frame to control the lifting distance between the two groups of electric hoist assemblies to prevent safety hazards caused by being too close or too far. The hook assembly in this device adopts a hook that can arbitrarily change the lifting angle and rotation. Therefore, its hook form can prevent the installation hazard of the sling being entangled due to the rotation of the hoisted object. In addition, a spring clip assembly is provided on the hook assembly of this device, which can prevent the hooked objects from falling off the hook component and causing safety accidents.

[0032] 3. Through the setting of the fixed positioning structure, the fixed positioning structure includes a slide rail component, a positioning structure frame, a positioning groove, a telescopic cylinder component, and an adjusting rod structure. The slide rail component is used in conjunction with the adjusting rod structure. The height of the fixed positioning structure is adjusted by the adjusting rod structure. The corresponding fixed positioning structure slides to a corresponding height on the slide rail component. The width of the positioning groove on the positioning structure frame is generally larger than the width of the civil air defense door on the market. It can be seen that it has a wide range of applications. The telescopic cylinder components on both sides push the telescopic rod to move relative to each other so that the civil air defense door placed in the positioning groove is clamped. Combined with the electric hoist lifting assembly, the stability of the civil air defense door during lifting is guaranteed, reducing the safety hazards caused by shaking.

An operating method for a hoisting device for processing and installing a civil air defense door according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: First, the height of the hoisting device (1) is aligned with the height of the installation site by using the electric lifting structure (3) on the hoisting device (1), and the electric lifting structure (3) uses the electric lifting cylinder component (27) to push the lifting column structure (30) up and down, thereby achieving height adjustment; Step 2: After adjusting the height, use the hook component (20) on the electric hoist assembly (10) to hook the hook ring mechanism of the civil air defense door, and then drive the motor component (15) to operate to rotate the rotating shaft in the noose assembly (14), and at the same time, reel in the double-strand steel cable (16). The reeling process is carried out slowly. When the double-strand steel cable (16) is straightened and the civil air defense door is started, the driving motor component (15) is stopped and the driving component (13) is started to make the two sets of electric hoist assemblies (10) perpendicular to the two hook ring mechanisms to ensure the safety of the device during operation. After the adjustment is completed, the driving motor component (15) continues to work and operates the rotating shaft in the noose assembly (14) to achieve reeling, and finally the purpose of lifting the civil air defense door is achieved; Step 3: According to the principle of convenient installation, the height of the fixed clamping structure (7) is adjusted by adjusting the rod structure (37) and the slide rail component (32). After the adjustment, the suspended civil air defense door is reversed by the driving motor component (15) to release the rope of the noose assembly (14), so that the lower two corners of the civil air defense door are respectively placed in the clamping grooves (34) of the clamping structure frames (33) of the two sets of fixed clamping structures (7), and then the telescopic cylinder component (35) pushes the telescopic rod to clamp the inserted civil air defense door, and then the driving motor component (15) makes the double-strand steel cable (16) tight; Step 4: Finally, install it on the fixed civil air defense door according to the installation drawing until the installation is completed. After the final installation of the civil air defense door is completed, put it down and then load it onto a truck and transport it to the civil air defense installation site for installation.
