Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment technology, and more specifically to a hoisting tool for prefabricated components and a hoisting system including the prefabricated component. Background Technology

[0002] Currently, the hoisting of precast components typically uses cranes or tower cranes as hoisting equipment. The precast components are hoisted by hooks, but the hooks themselves do not have the function of automatically adjusting verticality, flatness, or fine-tuning height. The crane or tower crane operator simply operates the hook to control the lifting and installation of the precast components, which requires on-site manual command and coordination. This is inefficient and results in large installation errors. The horizontality and verticality can only be adjusted manually after the precast components are hoisted into place, which is inefficient, labor-intensive, and has large errors, with errors at the centimeter level. Furthermore, the existing hoisting equipment cannot be adjusted horizontally according to the precast components to be hoisted, and multi-level adjustment (fine-tuning) cannot be achieved during the hoisting process.

[0003] Therefore, how to provide a lifting tool that can adjust the level and height of the precast components to be lifted is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a lifting device for prefabricated components and a lifting system including the device, aiming to solve one of the problems in the background art mentioned above, and to realize the horizontal adjustment of the prefabricated components to be lifted during the lifting process.

[0005] On the one hand, in order to achieve the above objectives, this utility model provides a lifting device for prefabricated components, which adopts the following technical solution: A lifting device for precast components, comprising: The first beam is equipped with a first lifting device on its upper part, and the first lifting device is connected to the first beam. The second beam is located below the first beam. Two second lifting devices are symmetrically arranged between the first beam and the second beam, and the second lifting devices are respectively connected to the first beam and the second beam via ropes. The second beam is equipped with multiple lifting connectors, which are spaced apart along the length of the second beam and are symmetrically arranged with respect to the middle position of the second beam. The third lifting device is provided in an even number, and the even number of third lifting devices are divided into two groups. The two groups of third lifting devices are symmetrically arranged below the second beam, and the third lifting devices are connected to the lifting connectors on the second beam by ropes. The third lifting device is equipped with a hook. The controller is electrically connected to the first, second, and third lifting devices respectively.

[0006] Furthermore, two connecting plates are symmetrically arranged on the first beam, and the two connecting plates are connected by ropes. The hook of the first hoist is connected to the middle position of the rope between the two connecting plates.

[0007] Furthermore, the lifting connector is a lifting lug, which is provided with a lifting hole, and the third lifting device is connected to the lifting hole by a rope.

[0008] Furthermore, the lifting device for the precast component also includes a generator, which is located above the second beam and is electrically connected to the controller, the first lifting device, the second lifting device, and the third lifting device.

[0009] Furthermore, the first, second, and third lifting devices are all electric hoists.

[0010] On the other hand, this utility model also provides a hoisting system, including the hoisting device for the prefabricated components described above, and also includes a crane, a distance sensor, a level sensor, a camera, and monitoring equipment; The crane is connected to the first lifting device; The camera is positioned above the lifting device; Both the distance sensor and the level sensor are mounted on the prefabricated component to be hoisted.

[0012] Furthermore, the hoisting system also includes an alarm device, which is electrically connected to the processor.

[0013] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a lifting device for precast components and a lifting system including the device. By setting two second lifting devices between the first beam and the second beam, the positional relationship between the first beam and the second beam can be adjusted. By setting two sets of third lifting devices below the second beam, during the lifting process of the precast component, the two sets of third lifting devices are used to hook the two ends of the precast component. By controlling the two sets of third lifting devices, the precast component can be leveled, thereby improving the installation accuracy and efficiency of the precast component.

[0017] 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.

[0018] On the one hand, see Figure 1 This utility model discloses a lifting device for prefabricated components, comprising: The first beam 1 is equipped with a first lifting device 2 above it, and the first lifting device 2 is connected to the first beam 1. The second beam 3 is located below the first beam 1. Two second lifting devices 4 are symmetrically arranged between the first beam 1 and the second beam 3. The second lifting devices 4 are connected to the first beam 1 and the second beam 3 respectively by ropes. Multiple lifting connectors 5 are provided on the second beam 3. The multiple lifting connectors 5 are spaced apart along the length of the second beam 3, and the multiple lifting connectors 5 are symmetrically arranged with the middle position of the second beam 3 as the center. The third lifting device 6 is provided in an even number. The even number of third lifting devices 6 are divided into two groups. The two groups of third lifting devices 6 are symmetrically arranged below the second beam 3. The third lifting devices 6 are connected to the lifting connector 5 on the second beam 3 by ropes. The third lifting device 6 is equipped with a hook. The controller is electrically connected to the first lifting device 2, the second lifting device 4, and the third lifting device 6, respectively.

[0019] It should be noted that during use, the first lifting device 2 is connected to a crane, which can be a crane or a tower crane. By connecting the third lifting device 6 to different lifting connectors 5, it can adapt to the lifting of precast components of different specifications. With the two sets of third lifting devices 6, the controller can control one set of third lifting devices 6 to achieve the horizontal adjustment of the precast components. Especially when lifting irregularly shaped precast components, the adjustment of the third lifting device 6 can adjust the irregularly shaped precast components horizontally. At the same time, by using the controller to adjust the two second lifting devices 4 simultaneously, the height of the precast components can be finely adjusted.

[0020] According to some embodiments of this utility model, two connecting plates 7 are symmetrically arranged on the first beam 1. The two connecting plates 7 are connected by ropes, and the hook of the first hoist 2 is connected to the middle position of the rope between the two connecting plates 7. The arrangement of the two connecting plates 7 can ensure that the first beam 1 is in a horizontal state, thus ensuring the stability of the first beam 1 during hoisting.

[0021] In this embodiment, preferably, the lifting connector 5 is a lifting lug with a lifting hole 8, and the third lifting device 6 is connected to the lifting hole 8 by a rope. The lifting lug is connected to the second beam 3 by welding.

[0022] According to some embodiments of this utility model, the lifting device for the precast component also includes a generator 9, which is disposed above the second beam 3. The generator 9 is electrically connected to the controller, the first lifting device 2, the second lifting device 4, and the third lifting device 6. By installing the generator 9 on the second beam 3 and supplying power to the controller, the first lifting device 2, the second lifting device 4, and the third lifting device 6 through the generator 9, the lifting device can be made to operate without remote cable connections.

[0023] In the above embodiments, preferably, the first lifting device 2, the second lifting device 4, and the third lifting device 6 are all electric hoists.

[0024] On the other hand, see Figure 2 and 3 The present invention also provides a hoisting system, including the hoisting device for the prefabricated components mentioned above, and also including a crane, a distance sensor, a level sensor, a camera and monitoring equipment; The crane is connected to the first lifting device 2; The camera is positioned above the hoisting device; Both the distance sensor and the level sensor are installed on the prefabricated component 10 to be hoisted; The monitoring equipment is connected to a distance sensor, a level sensor, and a camera.

[0025] It should be noted that during the hoisting process of prefabricated components, a standard line is first set at a certain height on the prefabricated component. A distance measuring sensor and a level sensor are then set at the standard line position on the prefabricated component. The distance measuring sensor can monitor the hoisting height of the prefabricated component, and the level sensor can monitor the levelness of the prefabricated component. Once the prefabricated component is hoisted to the preset height and is in a horizontal state, the controller then adjusts the first hoist 2 or the two second hoist 4 to achieve the installation of the prefabricated component. The camera is set up to facilitate the monitoring of the hoisting environment and hoisting status.

[0026] In this embodiment, preferably, the monitoring device includes a processor and a monitor. The monitor is electrically connected to the processor, and the processor is electrically connected to a ranging sensor, a level sensor, and a camera. The monitor can monitor the footage of the prefabricated components during the hoisting process, and can monitor whether the prefabricated components have reached the prefabrication height and are in a horizontal position.

[0027] In this embodiment, preferably, the hoisting system also includes an alarm device electrically connected to the processor. By setting the alarm device, a preset height from the installation position of the prefabricated component is used as a warning height. When the prefabricated component is lowered to the warning height, the alarm device issues a warning to remind the installers to proceed with the installation. This avoids personal injury to construction personnel in the installation area during the hoisting process. This hoisting system also improves installation accuracy, reducing the centimeter-level installation error in existing technologies to the millimeter level.
