Description
Technical Field
[0001] This utility model relates to the field of hanger technology, specifically a self-balancing electromechanical installation hanger. Background Technology
[0002] Self-balancing scaffolds play a vital role in modern construction, with a wide range of applications. They are not limited to transporting and hoisting various electromechanical equipment, but also cover the installation of large components such as glass curtain walls and steel beams. They significantly improve the efficiency of construction site operations, effectively reduce reliance on human resources, and lower labor intensity.
[0003] Chinese patent CN220432023U discloses a self-balancing hanger that achieves dynamic balance control of steel beam structures during hoisting by utilizing the movement mechanism of counterweights.
[0004] However, traditional two-end hoisting methods are not suitable for special loads such as electromechanical equipment. Due to their complex structure and uneven center of gravity distribution, electromechanical equipment often requires a multi-point hoisting strategy to ensure stability and safety during the hoisting process. This patent, however, does not consider this requirement, and the drive motor is mounted on one side of the hanger. This asymmetrical layout may adversely affect the overall balance of the hanger to some extent. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-balancing electromechanical installation hanger to solve the problems mentioned in the background art.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a self-balancing electromechanical installation hanger, the structure of which includes a cross beam, the top of the cross beam is provided with multiple upper lifting rings connected to steel wire ropes, the bottom of the cross beam is provided with an adjustment box, the adjustment box is provided with a center of gravity adjustment mechanism, the center of gravity adjustment mechanism includes an internal gear ring, the bottom of the adjustment box is provided with a fixed shaft, a rotating plate is rotatably connected to the fixed shaft, the end of the rotating plate is provided with a drive motor, the output shaft of the drive motor is connected to a drive gear, the drive gear meshes with the internal gear ring, a slider is slidably fitted on the rotating plate, the slider is provided with a counterweight and a rotary motor, the output shaft of the rotary motor is connected to a drive gear, a rack is provided on the side wall of the rotating plate, and the drive gear meshes with the rack.
[0007] Furthermore, the adjustment box includes a box base plate, and an outer baffle is provided on the box base plate. The outer baffle is fixedly connected to the bottom of the cross beam by bolts, and the center of gravity adjustment mechanism is connected to the box base plate.
[0008] Furthermore, the bottom of the rotating plate is equipped with casters.
[0009] Furthermore, the cross beam is formed by cross-welding of horizontal and vertical bars, with limiting plates at the ends of the horizontal and / or vertical bars, and lower connecting plates at the ends of the horizontal and vertical bars. A lower lifting ring is installed at the bottom of the lower connecting plate, and several through holes are provided at the bottom of the lower connecting plate.
[0010] Furthermore, the top of the horizontal and vertical bars is provided with several upper lifting rings, and pressure sensors are installed at the junction of the upper lifting rings and the wire rope. The four pressure sensors are connected to the control board and the wireless module.
[0011] Furthermore, a mobile counterweight mechanism is provided on the top of the regulating box. The mobile counterweight mechanism includes a first water bladder, a second water bladder, a third water bladder, and a fourth water bladder. A first water pump is provided between the first water bladder and the second water bladder, a second water pump is provided between the second water bladder and the third water bladder, a third water pump is provided between the third water bladder and the fourth water bladder, and a fourth water pump is provided between the fourth water bladder and the first water bladder.
[0012] Furthermore, a rope-supporting mechanism is provided between the multiple wire ropes. The rope-supporting mechanism includes a support ring, and the support rod is provided with several through holes. The through holes are capable of accommodating the wire ropes to pass through. A locking bolt is threaded to the outside of the support ring, and the locking bolt cooperates with the through holes.
[0013] Furthermore, a cross is formed in the middle of the support ring, and multiple steel wire rope suspension points are connected to lead weights, with the lead weights located at the center of the cross.
[0014] Furthermore, the top of the lower connecting plate is inverted U-shape, and the U-shaped part of the lower connecting plate is engaged with a horizontal or vertical rod. The U-shaped part is provided with an elastic pin and is limited by a retaining spring.
[0015] The beneficial effects of this utility model are:
[0016] This invention features an adjustment box and a center-of-gravity adjustment mechanism at the bottom of the cross beam. By rotating a drive motor and a rotary motor, the rotating plate and sliding block can be driven to rotate, thereby adjusting the position of the counterweight and achieving dynamic adjustment of the center of gravity. The center of gravity of the hanger can be adjusted in real time according to usage requirements, ensuring balance during hoisting. The design of the adjustment box facilitates the installation and maintenance of the center-of-gravity adjustment mechanism.
[0017] Because multiple wire ropes are connected by a rope support mechanism, the wire ropes can be stably hoisted at multiple points, which can adapt to the complex structure and uneven distribution of the center of gravity of the electromechanical equipment, and improve the stability and safety of hoisting.
[0018] By installing a mobile counterweight mechanism on the top of the adjustment box, when the center of gravity adjustment mechanism malfunctions or cannot work, the tilting problem of the equipment can be observed through the water bladder of the mobile counterweight mechanism. The water bladder can be adjusted by multiple water pumps, thereby realizing the mobile adjustment of the counterweight and ensuring the balance of the hanger. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] like Figures 1-4 As shown, a self-balancing electromechanical installation hanger includes a cross beam 1, which is formed by cross-welding horizontal rods 11 and vertical rods 12. Limiting plates 13 are provided at the ends of the horizontal and / or vertical rods. Lower connecting plates 2 are provided at the ends of the horizontal and vertical rods, and lower lifting rings 3 are installed at the bottom of the lower connecting plates. The bottom of the lower connecting plates has several through holes 21 at different vertical heights, allowing the lifting rings to be installed in holes at different heights to accommodate different lifting requirements. The top of the lower connecting plate is inverted U-shape, and the U-shaped portion of the lower connecting plate is engaged with a horizontal or vertical rod. The U-shaped portion has elastic pins 22 and is limited by retaining springs 23. Several upper lifting rings 4 are provided at the bottom of the horizontal and vertical rods, and the upper lifting rings can be connected to a crane via wire ropes 5. An adjustment box 6 is provided at the bottom of the cross beam, and the adjustment box contains a center-of-gravity adjustment mechanism for dynamically adjusting the center of gravity of the hanger.
[0034] The center of gravity adjustment mechanism includes an internal gear ring 63. A fixed shaft 64 is located at the bottom of the adjustment box, and a rotating plate 65 is rotatably connected to the fixed shaft. A drive motor 67 is located at the end of the rotating plate, and a drive gear 66 is connected to the output shaft of the drive motor. The drive gear meshes with the internal gear ring. A slider 71 is slidably fitted on the rotating plate, and a counterweight 75 and a rotary motor 72 are mounted on the slider. A drive gear 73 is connected to the output shaft of the rotary motor, and a rack 74 is located on the side wall of the rotating plate, meshing with the drive gear. By rotating the drive motor and the rotary motor, the rotating plate can be rotated and the slider can be slid, thereby adjusting the position of the counterweight and achieving dynamic adjustment of the center of gravity.
[0035] The bottom of the rotating plate is equipped with casters, which serve to assist in movement and provide support.
[0036] In at least one embodiment, the regulating box includes a box base plate 62, an outer baffle 61 is provided on the box base plate, the outer baffle is fixedly connected to the bottom of the cross beam by bolts, and a center of gravity adjustment mechanism is provided on the box base plate.
[0037] Furthermore, a support plate 14 is provided at the bottom of the cross beam.
[0038] To further improve the balance of the lifting frame, pressure sensors can be installed at the junction of the upper lifting ring and the wire rope. Four pressure sensors are connected to the control board and wireless module to transmit the pressure values at that point in real time. When the pressure values at the four contact points are approximately equal, it indicates that the lifting frame is in a balanced state, making the lifting operation more stable and less prone to problems. By monitoring the pressure values in real time through the monitoring system, any imbalances during the lifting process can be detected and adjusted promptly, ensuring the safe execution of the lifting operation.
[0039] In at least one embodiment, such as Figure 5 As shown, the top of the regulating box is provided with a mobile counterweight mechanism, which includes a first water bladder 81, a second water bladder 82, a third water bladder 84 and a fourth water bladder 85.

[0040] The water flow can be clockwise or counterclockwise. If the third water bladder is heavier and the equipment tilts, the first and second water pumps will not work, while the third and fourth water pumps will work, causing the water in the water bladder to flow into the first water bladder at the diagonal, thereby achieving the flow regulation of the counterweight.
[0041] In at least one embodiment, a rope support mechanism 9 is provided between the plurality of wire ropes.
[0042] Furthermore, such as Figure 6 , Figure 7 As shown, the rope support mechanism includes a support ring 91, and the support rod is provided with a plurality of through holes 21, which can accommodate the steel wire rope 5 to pass through. The outer side of the support ring is threaded with a locking bolt 93, which cooperates with the through holes.

[0043] Furthermore, a cross 94 is formed in the middle of the support ring, and multiple wire rope suspension points are connected to plumb bobs, with the plumb bobs located at the center of the cross to ensure the stability of the hoisting.
[0044] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.
