Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a prefabricated plate hoisting device for assembled buildings. Background Art

[0002] Prefabricated construction involves transferring much of the on-site work involved in traditional construction methods to a factory. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are then manufactured in the factory and transported to the construction site for assembly and installation using reliable connections. This construction method represents the development direction of modern industrialized production and offers several significant characteristics and advantages. Prefabricated panels in prefabricated buildings refer to building panels, such as precast concrete panels and precast steel structural panels, that are prefabricated in the factory through processes such as mold processing, rebar tying, and concrete pouring. These prefabricated panels undergo strict quality control in the factory to ensure precise dimensions and reliable quality.

[0003] In prefabricated buildings, it is usually necessary to hoist prefabricated panels. The Chinese utility model patent with the announcement number CN218809904U discloses a balancing hoist for hoisting all prefabricated panels of prefabricated buildings, comprising a first horizontal plate; two clamping devices are symmetrically installed below the first horizontal plate, and the clamping device includes a second horizontal plate, and two slides are symmetrically slidably installed at the bottom end of the second horizontal plate. The bottom ends of the two adjacent sides of the two slides are each constructed with a first clamping plate, and a second clamping plate is slidably installed above the first clamping plate. The bottom end of the second horizontal plate is symmetrically constructed with two vertical plates, and the two vertical plates are both threadedly connected with threaded rods. The utility model is provided with a second horizontal plate, a slide, a first clamping plate, and a second clamping plate. The two slides slide at the bottom end of the second horizontal plate, and the first clamping plate and the second clamping plate on the slide clamp the prefabricated panels. This facilitates clamping prefabricated panels of any size and does not damage the holes at both ends of the prefabricated panels.

[0004] However, during the use of this utility model, since multiple threaded rods are provided, when the staff needs to hoist the prefabricated panels, they need to manually rotate the threaded rods in sequence to fix the prefabricated panels, which affects the hoisting efficiency and cannot meet production needs. Therefore, a prefabricated panel hoisting device for assembled buildings is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a prefabricated panel lifting device for assembled buildings, which has the advantage of facilitating the lifting of prefabricated panels. It solves the problem that due to the provision of multiple threaded rods, when the staff need to lift the prefabricated panels, they need to manually rotate the threaded rods in sequence to fix the prefabricated panels, which affects the lifting efficiency and cannot meet production needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a prefabricated panel hoisting device for assembled buildings, comprising an installation box and a support plate arranged at the bottom of the installation box, a mounting plate being arranged on the front of the support plate, and a clamping mechanism extending to the bottom of the mounting plate being arranged on the top of the mounting plate;

[0009] Furthermore, a transmission hook is rotatably mounted on one end of the first clamping rod close to the hinge seat on the front side, and a protrusion that abuts against the transmission hook is fixedly connected to the front side of the second clamping rod.

[0010] Furthermore, there are two support plates, which are symmetrically distributed at the bottom of the installation box, and a mounting plate is distributed on the front and back of each support plate.

[0011] Furthermore, the side of the mounting plate close to the mounting box is fixedly connected to an extension plate extending into the interior of the support plate, and one side of the support plate is threadedly connected to a fixing bolt extending into the interior of the extension plate, and a threaded hole compatible with the fixing bolt is opened inside the extension plate.

[0012] Furthermore, a driving motor is fixedly installed on one side of the installation box, and a bidirectional threaded rod extending into the interior of the installation box is fixedly connected to the output shaft of the driving motor, and a threaded sleeve is connected to the external thread of the bidirectional threaded rod.

[0013] Furthermore, a connecting block is fixedly connected between the threaded sleeve and the support plate, a fixing plate is fixedly connected inside the installation box, and the bidirectional threaded rod is rotatably connected to the fixing plate.

[0014] Furthermore, two mounting rings are fixedly connected to the top of the mounting box, a lifting ring is provided on the top between the two mounting rings, and cables are fixedly connected between the lifting ring and the two mounting rings.

[0015] Compared with the prior art, the present invention provides a prefabricated panel hoisting device for assembled buildings, which has the following beneficial effects:

[0016] 1. The prefabricated panel lifting device for assembled buildings is equipped with an electric push rod to drive the articulated seat to move up and down, and then the articulated seat simultaneously drives the two first articulated rods and the second articulated rods to rotate. At this time, the second articulated rod will simultaneously drive the first clamping rod and the transmission hook to rotate, and then the transmission hook can drive the second clamping rod to rotate. At this time, the rotation directions of the first clamping rod and the second clamping rod are opposite, which is convenient for hooking the lifting ring on the prefabricated panel, thereby achieving the effect of facilitating the lifting of the prefabricated panel.

[0017] 2. The prefabricated panel lifting device for assembled buildings is capable of adjusting according to the length of the prefabricated panel by setting a driving motor to rotate the bidirectional threaded rod, and then driving the threaded sleeve and the support plate to move through the bidirectional threaded rod, thereby improving the practicality of the device and solving the problem that due to the setting of multiple threaded rods, when the staff need to lift the prefabricated panel, they need to manually rotate the threaded rods in sequence to fix the prefabricated panel, which affects the lifting efficiency and cannot meet the production needs.
