Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, specifically to a hoisting equipment for prefabricated building construction. Background Technology

[0002] Prefabricated construction refers to the prefabrication of building components such as exterior wall panels, composite slabs, air conditioning panels, and precast beams in a factory, followed by transportation to the construction site for installation. This eliminates the need for on-site pouring, thus improving work efficiency. At the construction site, the transported prefabricated components need to be hoisted to their installation location. For example, Chinese Patent CN202111172792.7 discloses a prefabricated building hoisting device, which improves the stability of the hoisting by adding a hoisting platform consisting of a hanger and a support frame to the existing hoisting ropes. Similarly, Chinese Patent CN202310055785.1 discloses a green and energy-saving prefabricated building decorative wall panel hoisting system and method, in which the prefabricated building decorative wall panels are manually placed onto a hoisting frame, with the bottom of the panel resting on a base plate. A wall panel limiting frame is then used to restrain the panel from the front, preventing it from tilting.

[0003] Based on the search, it can be found that some existing precast components are not standard in shape, and the materials used in some parts of the precast components may be different. As a result, when the precast components are placed on the hoisting equipment, the center of gravity of the precast components may not coincide with the vertical extension line of the hook on the hoisting equipment. Consequently, the precast components and the base of the hoisting equipment used to support the precast components may tilt and deflect together. Once tilted, it will affect the subsequent installation of the precast components and reduce the stability of the hoisting, thus resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a hoisting device for prefabricated building construction, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hoisting equipment for prefabricated building construction, comprising:

[0009] Four positioning elements are respectively disposed around the base;

[0010] The system includes a horizontal detection mechanism and a moving mechanism, both of which are located on the inner wall of the base. When the base is tilted in all directions, the horizontal detection mechanism can automatically detect the tilt and drive the moving mechanism to operate. The moving mechanism can adjust the horizontal state of the base.

[0011] A lubrication component is disposed on the inner wall of the base. When the moving mechanism is in operation, the lubrication component can inject lubricant into the level detection mechanism.

[0012] The positioning mechanism is located on the upper surface of the base and can drive the four positioning components to move synchronously and relative to each other, thereby centering the prefabricated components.

[0013] Optionally, the horizontal detection mechanism includes:

[0014] Four guide slots are provided, all of which are located inside the base. Sliding elements are slidably connected inside the guide slots. Two opposing guide slots are connected to each other through a connection port. Pressure sensors are fixedly installed at the ends of the guide slots. When the pressure sensors are squeezed, they can send signals to the control board via a wireless signal transmitter.

[0015] Optionally, the moving mechanism includes:

[0016] Four motors are provided. The outer casing of each motor is fixedly connected to the inner wall of the base via a bracket. A screw is fixedly connected to the rotating part of each motor. A slider is threadedly connected to the threaded part of the screw. The outer surface of the slider is slidably connected to the inner wall of the base. A counterweight is fixedly connected to the outer surface of the slider.

[0017] Optionally, the lubrication component includes:

[0018] A U-shaped shell is fixedly connected to the inner wall of the base. A cam is fixedly connected to the outer surface of the screw. A push plate is abutted at the end of the cam. A piston rod is fixedly connected to the outer surface of the push plate. A piston shell is slidably connected to the outer surface of the piston rod. A piston head is fixedly connected to the end of the piston rod. A spring is fixedly connected to the opposite side of the piston shell and the push plate.

[0019] Optionally, the connecting component includes:

[0020] Optionally, the positioning mechanism includes:

[0021] The inlet pipe and the outlet pipe are both fixedly connected to the side of the piston housing. Both the inlet pipe and the outlet pipe are equipped with a one-way valve. The end of the inlet pipe is fixedly connected to the U-shaped shell, and the end of the outlet pipe is connected to the guide groove.

[0022] Motor 2, the outer shell of motor 2 is fixedly connected to the lower surface of the base, a rotating rod is fixedly connected to the rotating part of motor 2, a rotating component is fixedly connected to the end of the rotating rod, the end of the rotating component has four slots, a sliding rod is slidably connected to the slot wall of the slot, a moving block is fixedly connected to the upper surface of the sliding rod, four limiting components are fixedly connected to the lower surface of the base, the inner side of the limiting components has a sliding opening for the moving block to pass through and slidably connect thereto, a kit is fixedly connected to the end of the moving block, a sleeve rod is slidably connected to the inner wall of the kit, a spring 2 is fixedly connected to the opposite side of the sleeve rod and the inner wall of the kit, and the end of the sleeve rod is fixedly connected to the side of the positioning component.

[0023] Optionally, a clamping pad is installed on the side of the positioning member facing the base, and the clamping pad is made of rubber.

[0024] Optionally, the four counterweights are located at the horizontal and vertical center lines of the base, respectively, and the positions of the counterweights correspond to the sliding members.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] I. When the base is tilted in all directions, the horizontal detection mechanism can automatically detect the tilt and drive the moving mechanism to operate. The moving mechanism can adjust the horizontal state of the base. This method uses four sliders set on the horizontal and vertical center lines inside the base to detect the tilt in all directions. This allows for intelligent detection of the tilt and the application of a movable counterweight to apply a force in the opposite direction of the tilt, thus achieving balance. This eliminates the need for manual adjustment and improves efficiency.

[0027] Second, when the moving mechanism of this invention is in operation, the lubrication component can inject lubricant into the horizontal detection mechanism. When adjusting the balance of the base, the internal detection sliding parts are sprayed with lubricant to reduce the large frictional resistance between the sliding parts and the guide groove, thereby ensuring the accuracy of the detection. It can also wash away dust and impurities that may appear in the guide groove to avoid hindering the movement of the sliding parts, thus maintaining the sliding form of the sliding parts. There is no need for manual addition of lubricant, and the degree of automation is better.

[0028] Third, the present invention enables the four positioning components to move synchronously and relative to each other through the operation of the positioning mechanism, thereby centering the prefabricated component. This method can pre-position the prefabricated component at the center of the base, thus initially preventing the prefabricated component from deviating from the center of the base when it is hoisted. It also provides efficient positioning and clamping of the prefabricated component to achieve a stable effect, preventing the prefabricated component from shaking or other unstable situations. Furthermore, it eliminates the need for users to lock it with external clamps, thus improving practicality and safety. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figures 1 to 6This embodiment provides a technical solution: a hoisting equipment for prefabricated building construction, including: a base 1, a hoisting component 2, a hook 3, a hoisting rope 4, a positioning component 5, a horizontal detection mechanism, a moving mechanism, and a lubrication component.

[0039] More specifically, in this embodiment: In actual use, due to the different shapes of the prefabricated parts and the different materials used in certain areas, the center of gravity of the prefabricated part may not coincide with the vertical extension line of the hook 3, resulting in the base 1 and the prefabricated part deflecting together. Therefore, this method can sense the deflection of the base 1, and through tilting gravity and sliding, it can sense the direction of deflection, and can manipulate the moving mechanism to move in the opposite direction of deflection, thereby gradually leveling the base 1. In addition, the lubrication component can continuously lubricate the horizontal calibration mechanism to reduce frictional resistance.

[0040] It is worth noting that this embodiment also includes a positioning mechanism.

[0041] More specifically, in this embodiment: in actual use, the prefabricated component placed on the base 1 needs to be positioned in advance. The control board will operate the positioning mechanism to move relative to each other from four directions of the prefabricated component, thereby positioning the prefabricated component at the center of the base 1 so that the center of gravity of the prefabricated component is close to the center of gravity of the base 1, in order to prepare for the subsequent hoisting and leveling of the prefabricated component, and to clamp the prefabricated component to prevent the prefabricated component from shaking during hoisting.

[0042] Among them, a clamping pad 30 is installed on the side of the positioning component 5 facing the base 1, and the clamping pad 30 is made of rubber.

[0043] More specifically, in this embodiment: in actual use, the rubber clamping pad 30 can increase the contact force between the positioning member 5 and the prefabricated component through its own elastic contraction, and through air deformation, the clamping pad 30 can better fit the prefabricated component with irregular shape, thus improving the positioning stability.

[0044] Example 2:

[0045] Based on the above embodiments:

[0046] Please see Figure 1 , Figure 2 and Figure 6 The horizontal detection mechanism in Embodiment 1 is disclosed as follows: the horizontal detection mechanism includes:

[0047] Four guide grooves 6 are all opened inside the base 1. A slider 7 is slidably connected inside the guide groove 6. Two opposite guide grooves 6 are connected to each other through a connection port 8. A pressure sensor 9 is fixedly installed at the end of the guide groove 6. When the pressure sensor 9 is squeezed, it can send a signal to the control board through a wireless signal transmitter.

[0048] More specifically, in this embodiment: In actual use, due to the asymmetrical shape of the prefabricated component or the different materials used, the center of gravity of the prefabricated component may deviate after it is positioned at the center, resulting in the base 1 tilting. When one side tilts, the slider 7 on one side can slide in the guide groove 6, thereby causing the slider 7 to press against the sensing part of the pressure sensor 9 under the action of gravity and tilt. After the pressure sensor 9 detects the pressure signal, it can promptly send the signal to the control board, which can then promptly operate the moving mechanism to adjust the base. The horizontal state of base 1 ensures that the prefabricated components on base 1 remain horizontal. The deflection of base 1 may be a unilateral deflection to the left or right, or a deflection in two directions such as forward, backward, left, and right. Therefore, this method uses four sliders 7 set on the horizontal and vertical center lines of base 1 to achieve directional sensing when base 1 deflects in all directions. Once base 1 is leveled, sliders 7 may not reset, but the pressure applied to pressure sensor 9 will decrease or disappear, thus avoiding continuous sensing. Therefore, the sensing practicality of this method is better.

[0049] Example 3:

[0050] Based on the above embodiments:

[0051] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The following disclosure is made regarding the moving mechanism in Embodiment 1, which includes:

[0052] Four motors 10 are provided. The outer casing of each motor 10 is fixedly connected to the inner wall of the base 1 via a bracket. A screw 11 is fixedly connected to the rotating part of each motor 10. A slider 12 is threadedly connected to the threaded part of the screw 11. The outer surface of the slider 12 is slidably connected to the inner wall of the base 1. A counterweight 13 is fixedly connected to the outer surface of the slider 12.

[0053] More specifically, in this embodiment: as Figure 6 and Figure 2As shown, when the pressure sensor 9 on the left detects a pressure signal, the control board receives the signal and drives the motor 10 on the right to rotate, thereby driving the screw 11 to rotate. Under the screw drive and sliding restriction, the counterweight 13 and slider 12 on the right move to the right, gradually causing the base 1 to shift to the right, and finally making the base 1 reach a horizontal state. When the left and upper sides shift simultaneously, the two motors 10 can be driven to rotate synchronously to achieve the effect of leveling the base 1. Because when the base 1 is used to hoist the prefabricated components, Some precast components may have asymmetrical shapes or different materials in certain areas, resulting in the center of gravity not being on the center line. Therefore, after the precast component is positioned, the center of gravity is not on the center line. When the precast component is lifted, it may tilt because the center of gravity is not aligned with the vertical center extension line of the hook 3. Tilting poses a safety hazard during lifting operations and is not conducive to subsequent assembly work. Therefore, in this method, a movable counterweight 13 can be used to apply a force in the opposite direction of the tilt, thereby achieving a balancing effect without the need for manual adjustment, thus improving efficiency.

[0054] Among them, the four counterweights 13 are located at the horizontal and vertical center lines of the base 1, respectively, and the positions of the counterweights 13 correspond to the sliders 7.

[0055] More specifically, in this embodiment: in actual use, the counterweight 13 and the guide groove 6 are directly opposite each other and are both located on the horizontal and vertical center lines of the base 1. Therefore, when it is necessary to adjust the level of the base 1, it is more convenient and intuitive. The level of the base 1 can be quickly adjusted by simply moving the four counterweights 13.

[0056] Example 4:

[0057] Based on the above embodiments:

[0058] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The lubrication component in Embodiment 1 is disclosed as follows: the lubrication component includes:

[0059] U-shaped shell 14 is fixedly connected to the inner wall of base 1. A cam 15 is fixedly connected to the outer surface of screw 11. The end of cam 15 abuts against push plate 16. A piston rod is fixedly connected to the outer surface of push plate 16. A piston shell 17 is slidably connected to the outer surface of piston rod. A piston head is fixedly connected to the end of piston rod. A spring is fixedly connected to the opposite side of piston shell 17 and push plate 16. An inlet pipe 18 and an outlet pipe 19 are fixedly connected to the side of piston shell 17. A one-way valve is provided inside both inlet pipe 18 and outlet pipe 19. The end of inlet pipe 18 is fixedly connected to U-shaped shell 14. The end of outlet pipe 19 is connected to guide groove 6.

[0060] More specifically, in this embodiment: during actual use, when the horizontal detection mechanism operates, it drives the screw 11 to rotate. Under the threaded transmission and sliding restriction, the cam 15 rotates. Due to the pressure relationship and the elastic reset relationship of the push plate 16, the piston rod and piston head reciprocate within the piston housing 17. Under negative pressure, the lubricating fluid stored in the U-shaped shell 14 can be drawn through the inlet pipe 18. The lubricating fluid is input into the guide groove 6 through the piston housing 17 and the outlet pipe 19, thereby achieving the function of lubricating the internal sliding parts 7. Figure 6 As shown, when the base 1 is tilted to the left, the counterweight 13 on the right side moves laterally to the right, and the liquid outlet 19 on the right side injects lubricant into the guide groove 6. At the same time, the base 1 is tilted to the left, so the lubricant can flow into the guide groove 6 on the left side through the connection port 8 under the action of offset and gravity, so as to lubricate the sliding part 7 on the left side. This method has the function of spraying liquid to lubricate the internal detection sliding part 7 when adjusting the balance of the base 1, reducing the large frictional resistance between the sliding part 7 and the guide groove 6, thereby improving the accuracy of detection. It can also wash away dust and impurities that may appear in the guide groove 6 to avoid hindering the movement of the sliding part 7, so as to always maintain the sliding form of the sliding part 7. There is no need for manual addition of lubricant, the degree of automation is better, and each time lubricant is added, it is specifically added to the two guide grooves 6 on one side of the tilt direction.

[0061] It is worth noting that the lubricant used in this method can be a lubricating oil or other liquid that can reduce wear and maintain smooth sliding. The slider 7 used in this method can be cylindrical or spherical. If a spherical shape is used, the frictional resistance is the lowest. However, the slider 7 is more sensitive. When the base 1 shakes under the action of wind, it may react more sensitively and repeatedly self-drive adjustment. If a cylindrical shape is used, the sensitivity can be reduced to a certain extent without affecting the initial adjustment of the base 1.

[0062] A drain port is provided on the side of the base and connected to the guide groove 6 for draining the lubricant after use.

[0063] Example 5:

[0064] Based on the above embodiments:

[0065] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The positioning mechanism in Embodiment 1 is disclosed as follows: The positioning mechanism includes:

[0066] Motor 20, the outer shell of motor 20 is fixedly connected to the lower surface of base 1. A rotating rod 21 is fixedly connected to the rotating part of motor 20. A rotating component 22 is fixedly connected to the end of the rotating rod 21. The end of the rotating component 22 has four slots. A sliding rod 23 is slidably connected to the wall of the slot. A moving block 24 is fixedly connected to the upper surface of the sliding rod 23. Four limiting components 25 are fixedly connected to the lower surface of base 1. A sliding opening is opened on the inner side of the limiting component 25 for the moving block 24 to pass through and slidably connect thereto. A sleeve 26 is fixedly connected to the end of the moving block 24. A sleeve rod 27 is slidably connected to the inner wall of the sleeve rod 27. A spring 2 is fixedly connected to the opposite side of the inner wall of the sleeve rod 27 and the inner side of the sleeve rod 26. The end of the sleeve rod 27 is fixedly connected to the side of the positioning component 5.

[0067] More specifically, in this embodiment: during actual use, the control board manipulates the rotating part of motor 20 to operate, the rotating part of motor 20 drives the rotating rod 21 to rotate, which in turn drives the rotating component 22 and its four slots to rotate, such as... Figure 4 As shown, due to the sliding fit between the groove and the slide bar 23, the rotating component 22 drives the four moving blocks 24 to move inward when rotating counterclockwise. Ultimately, the four positioning components 5 position and lock the prefabricated component in four directions. The elastically telescopic sleeve 27 provides elastic force to the prefabricated component, thus adapting to various specifications of prefabricated components to a certain extent. This method can preposition the prefabricated component to the center of the base 1, thereby initially preventing the base 1 from deviating from the center and causing the base 1 to deflect when hoisting the prefabricated component. It also positions and clamps the prefabricated component to achieve a stable effect, preventing the prefabricated component from shaking or other unstable situations. The user does not need to lock it with external clamps, thus improving practicality and safety.

[0068] Working principle: The hoisting equipment used for prefabricated building construction has the following steps when in use:

[0069] S1: The user first installs the lifting component 2 onto the lifting equipment, and then places the prefabricated component to be lifted above the base 1.

[0070] S2: The control panel will then operate the positioning mechanism, which will drive the four positioning parts 5 to move relative to each other, thereby positioning the prefabricated part at the center of the base 1 and locking it.

[0071] S3: Due to the uncertainty of the shape and material of the prefabricated part, the center of gravity may deviate from the base 1, resulting in the base 1 deflecting. Therefore, the horizontal detection mechanism can quickly detect the actual deflection direction of the base 1 and transmit the signal to the control board.

[0072] S4: After receiving the signal, the control board will operate the moving mechanism to move the counterweight 13 in the opposite direction of the base 1's deflection direction, thereby ultimately leveling the base 1. During the adjustment process, the level detection mechanism will be continuously lubricated to ensure the detection accuracy of the level detection mechanism.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
