Technical Field
[0001] This utility model relates to the field of hoisting auxiliary technology, specifically to an auxiliary hoisting device for building electromechanical installation. Background Technology
[0002] When carrying out building electromechanical installation work, in order to ensure safety during hoisting of building electromechanical equipment, it is necessary to use hoisting auxiliary equipment to protect the hoisted electromechanical equipment and improve the installation efficiency of building electromechanical equipment.
[0003] However, existing hoisting auxiliary devices are relatively complex in structure and not convenient to operate. They still require manual handling before hoisting, which is labor-intensive and inefficient. While existing technologies may have solutions to these problems, this case aims to provide an alternative or replacement solution. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary hoisting device for building electromechanical installation, comprising: a hoisting bracket, an extended hoisting base, a hoisting winch, a counterweight adjustment structure, and a lifting and stretching structure. The hoisting bracket is mounted on the extended hoisting base, the hoisting winch is mounted on the hoisting bracket, the counterweight adjustment structure is mounted on the extended hoisting base, and the lifting and stretching structure is mounted on the hoisting bracket. The counterweight adjustment structure includes: two pairs of extended rotating brackets, two pairs of concave bearing blocks, four pairs of rotating angle shafts, two pairs of loop support blocks, four pairs of rotating transmission helical gears, two pairs of rotating drive helical gears, two pairs of rotating drive shafts, a rotating drive gear set, a rotating drive motor, two pairs of extended drive motors, two pairs of extended threaded rods, two pairs of extended threaded pipes, two pairs of cross-shaped extended blocks, two pairs of loop-shaped extended support blocks, two pairs of extended support blocks, multiple negative pressure fixing devices, and a counterweight adjustment assembly.
[0005] Two pairs of concave bearing blocks are mounted in a cross shape on the extended hoisting base. Two pairs of extended rotating brackets are respectively inserted into the two pairs of concave bearing blocks via pairs of rotating angle shafts. Two pairs of U-shaped support blocks are connected to the two pairs of concave bearing blocks and the four pairs of rotating angle shafts. Four pairs of rotary transmission helical gears are respectively mounted on the four pairs of rotating angle shafts. Two pairs of rotary drive shafts are respectively inserted into the two pairs of U-shaped support blocks. Two pairs of rotary drive helical gears are respectively mounted on the two pairs of rotary drive shafts. The rotary drive motor drive end is connected to the rotary drive gear set. Two pairs of extended rotating brackets... The frame has two pairs of extended cross slots. The two pairs of extended threaded rods are respectively inserted into the inner side of the two pairs of extended cross slots through bearings. The two pairs of extended threaded tubes are respectively fitted onto the two pairs of extended threaded rods. The two pairs of cross-shaped extended blocks are respectively movably inserted into the inner side of the two pairs of extended cross slots, and the two pairs of cross-shaped extended blocks are respectively fitted onto the two pairs of extended threaded tubes. The two pairs of spiral extended support blocks are respectively fitted onto the two pairs of cross-shaped extended blocks. The two pairs of extended support blocks are respectively installed on the two pairs of spiral extended support blocks. Multiple negative pressure fixing devices are evenly installed on the two pairs of extended support blocks. The counterweight adjustment assembly is installed on the two pairs of extended rotating brackets.
[0006] It should be noted that, as described above, the lifting bracket is supported by the extended lifting base. The rotary drive motor rotates, driving the rotary drive gear set on its drive end. This gear set drives two pairs of rotary drive shafts to rotate stably. These shafts then drive two pairs of rotary drive helical gears, which in turn drive four pairs of rotary transmission helical gears on the inner side of the two pairs of loop support blocks. These helical gears then drive four pairs of rotation angle shafts, which in turn drive two pairs of extended rotary brackets. These extended rotary brackets then rotate stably along two pairs of concave bearing blocks, thus advancing the extended rotary brackets... The device rotates stably, expanding the rotating support into a cross shape. Simultaneously, two pairs of expansion drive motors on the rotating support operate, driving the expansion threaded rods at their drive ends. These rods then drive the expansion threaded tubes, causing them to extend and retract stably along the rods. The extension threaded tubes, in turn, drive the cross-shaped expansion blocks, which in turn drive the spiral-shaped expansion support blocks, thus changing the position of the spiral-shaped expansion support blocks. These spiral-shaped expansion support blocks then drive their respective expansion support blocks, providing support for the entire device. A negative pressure fixing device further supports the expansion support blocks, and a counterweight adjustment component adjusts the overall support effect of the device.
[0007] Preferably, the lifting and stretching structure includes: a lifting concave block, multiple stretching screw modules, two pairs of adsorption lifting concave blocks, two pairs of adsorption convex telescopic blocks, two pairs of telescopic magnets, two pairs of telescopic electromagnets, and multiple negative pressure adsorbers.

Multiple stretching screw modules are respectively installed inside the two pairs of lifting and stretching grooves. Two pairs of adsorption lifting concave blocks are respectively installed on the moving ends of the multiple stretching screw modules. Two pairs of adsorption convex telescopic blocks are respectively movably inserted into the inside of the two pairs of adsorption lifting concave blocks. Two pairs of telescopic magnets are respectively installed inside the two pairs of adsorption lifting concave blocks. Two pairs of telescopic electromagnets are respectively installed inside the two pairs of adsorption lifting concave blocks. Multiple negative pressure adsorbers are evenly installed on the two pairs of adsorption convex telescopic blocks.
[0009] It should be noted that, as described above, the hoisting winch drives the lifting concave block, enabling it to rise and fall stably. The tension screw module on the lifting concave block drives the adsorption lifting concave block. The telescopic electromagnet inside the adsorption lifting concave block is energized, and the telescopic electromagnet magnetically attracts or repels the telescopic magnet. The telescopic magnet drives the adsorption convex telescopic block, causing it to stably extend and retract along the inner side of the adsorption lifting concave block. The adsorption convex telescopic block drives the negative pressure adsorber on it, thereby squeezing the negative pressure adsorber against the outer sidewall of the wall. The negative pressure lifting and stretching provides auxiliary lifting and stretching.

Multiple expansion sliders are respectively installed on the four pairs of horizontal telescopic boxes, and multiple expansion sliders are respectively movably inserted into the inner side of multiple expansion slides.
[0012] It should be noted that, as described above, the horizontal telescopic box drives the expansion slider on it, causing the expansion slider to perform stable horizontal extension and contraction along the movable inner side. The expansion slider drives the horizontal telescopic box on it, and through the counterweight liquid inside the horizontal telescopic box, the counterweight of the entire device is changed.
[0013] Preferably, each of the four pairs of horizontal telescopic boxes is equipped with a feeding valve and a discharging valve.
[0014] Preferably, auxiliary tension ropes are provided on both pairs of the extended rotating brackets and the hoisting brackets.

[0016] This utility model provides an auxiliary hoisting device for building electromechanical installation. It offers the following advantages compared to existing technologies: a four-way expansion support system employing a cross-shaped rotating bracket and a double-threaded rod drive structure, driven by an electric rotating mechanism with four sets of helical gears, enabling stepless expansion of the bracket from 0-90°. Combined with an embedded negative pressure fixing device and retractable support blocks, the support area of a single device is expanded to more than three times that of traditional solutions; an intelligent counterweight adjustment module, through dynamic adjustment of the liquid medium within four sets of horizontal telescopic boxes, combined with precise displacement control of the expansion slide, can respond in real time to center of gravity shifts, achieving rapid balance adjustment response. With a lifting speed of 0.3 seconds per lift, efficiency is significantly improved compared to traditional counterweight solutions. The magnetic negative pressure auxiliary lifting device uses a two-stage telescopic mechanism driven by an electromagnet, combined with an array of negative pressure adsorbers, which can achieve micro-adjustment of ±50mm and provide a maximum vertical adsorption force of 1200N / cm². The omnidirectional safety monitoring system integrates a balancer and an angle sensor, and ensures lifting accuracy of ≤±0.05° through a closed-loop control system.
