Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, in particular to a hoisting balancing device for installing prefabricated concrete components. Background Art
[0002] Prefabricated concrete structures (PC) are precast concrete components assembled through post-cast concrete joints, grout anchors, or superposition to create a structure that delivers reliable load transmission and bearing capacity. This flexible and adaptable structure offers advantages such as good integrity, ease of construction, shortened construction periods, reduced costs, reduced construction waste, and improved project quality.
[0003] At present, the on-site installation of prefabricated concrete components in China mostly uses tower cranes, truck cranes and other lifting equipment for lifting and installation.
[0004] For example, Chinese patent publication CN112758806A discloses a connection device and method for lifting a prefabricated concrete component. The document describes "a first connection module, two second connection modules, and a plurality of third connection modules, wherein the first connection module is provided with a crossbeam." This system, through its detachable and removable connection mechanism, greatly simplifies the construction process and effectively improves construction efficiency. It is particularly suitable for large, heavy concrete components with offset centers of gravity and high requirements for structural integrity. Its rational structural planning and ease of implementation make it suitable for widespread use.
[0005] For example, a Chinese patent document with publication number CN205367457U discloses a special hoist for installing precast concrete components, which states that "it includes a long horizontal lifting beam, with a component suspended at one end via a fixed pulley, and a rectangular hanging frame suspended at the other end via a fixed pulley, wherein a counterweight is installed in the rectangular hanging frame. If the component is a column-hanging component, the lifting device can be designed as a column-hanging lifting device structure, with the column-hanging component suspended at the long horizontal lifting beam via a short lifting beam." The present invention uses a counterweight at one end of the horizontal lifting beam to make the center of gravity of the component and the tower crane hook not on the same vertical line, so that the component can be lifted to just above the installation site, meeting the component lifting requirements.
[0006] However, the following defects or problems still exist in combination with the existing technology: during the installation of concrete components, due to the different weights at both ends of the concrete components, one side is often higher than the other side, which makes the installation of prefabricated concrete components difficult. Although publication number CN205367457U achieves installation balance by assembling a heavy object at the other end of the rectangular hanging frame, it is particularly troublesome in actual use. Each time a different concrete component is hoisted, the weight of the counterweight needs to be changed, and it is also inconvenient to adjust the inclination angle of the component according to actual usage when hoisting and installing the prefabricated concrete component. Summary of the Invention
[0007] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a hoisting balancing device for installing prefabricated concrete components.
[0008] In order to achieve the above object, the present invention adopts the following technical solutions:
[0009] The transmission gear of claim 1, wherein the gear is secured to the chassis at the bottom and the gear is engaged with the gear by a toothed connection at the bottom.
[0010] Preferably, there are multiple balancing blocks, which are arranged at equal distances. A slide rail is fixedly installed on the top inner wall of the shell. A slide groove is provided on the upper surface of the balancing block. The slide rail is slidably connected to the balancing block through the slide groove.
[0011] Preferably, the main controller includes a microcontroller, a gyroscope sensor, and a Bluetooth module. The gyroscope sensor and the Bluetooth module are electrically connected to the microcontroller, and the microcontroller is electrically connected to the motor.
[0012] Preferably, a plurality of equally spaced threaded holes are provided on both sides of the outer wall of the shell, the sling is slidably sleeved on the shell, the sling is sleeved with a fixing screw, the other end of the fixing screw is threadedly connected to the shell through the threaded hole, and through holes are provided on the upper and lower sides of the sling.
[0013] The beneficial effects of the present invention are:
[0014] 1. In the present invention, when the hoisting is unbalanced, an electrical signal is transmitted through an external remote control, and the Bluetooth module in the main controller receives the electrical signal transmitted by the remote control and transmits it to the microcontroller. The microcontroller controls the operation of the motor, and the motor drives the output shaft to rotate. The output shaft drives the driving shaft to rotate through gear 1 and gear 2. The driving shaft drives the chain to move through the driving sprocket. The chain drives the balancing block to move toward the upward end of the shell through the connecting piece, thereby adjusting the weight of the two ends of the shell to achieve the purpose of balance.
[0015] 2. In the present invention, since the position of the balancing block can be moved arbitrarily within the shell, the two ends of the shell can be tilted arbitrarily by adjusting the position of the balancing block during installation of the precast concrete component, which facilitates adjustment of the tilt angle of the component according to the actual use of the installation.
[0016] 3. In the present invention, since a gyroscope sensor is provided inside the housing, the balancing device can also automatically adjust the balance. The gyroscope sensor can detect which end the housing is tilted to, thereby transmitting an electrical signal to the microcontroller. The microcontroller controls the motor to start, and at this time the balance block moves toward the upwardly tilted end of the housing, thereby adjusting the weight of the two ends of the housing to achieve the purpose of balance.
