Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a sliding device for installing a prefabricated PK board. Background Art

[0002] In the construction industry, prefabricated buildings are developing at an unprecedented rate, particularly prefabricated PK panels. Prefabricated PK panels are first processed in the factory and can be transported directly to the construction site for installation. This eliminates the need for formwork support on site, improving construction efficiency and enhancing the appearance of the prefabricated PK panels.

[0003] At the construction site, prefabricated PK panels were hoisted and placed horizontally atop a pair of opposing walls. Precise positioning during on-site installation required a smooth lowering of the panels during hoisting and installation, especially after the second-floor steel frame construction was complete, as the floor slabs used large-span prefabricated PK panels. Because the second-floor steel beams had already been installed and the beam spacing was small, the first-floor prefabricated PK panels had a larger span. Therefore, it was impossible to directly place the panels through the second-floor steel beams in the corresponding position on the first floor, significantly impacting the installation process.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0036] In one embodiment;

[0042] The guide roller 15 is arranged at the bottom opening of the feeding frame 16 and is used to push the prefabricated plate to move along the guide assembly 12.

[0043] The supporting base 14 is arranged below the feeding frame 16 and is used to adjust the height of the guide roller 15.

[0044] In this embodiment, the equipment rack 11 is installed on the top plate of the construction site through the ceiling rack 13, the prefabricated PK plate can be suspended to the corresponding construction height through the suspension machine, the prefabricated PK plate is extended from the feeding frame 16, the supporting base 14 drives the guide roller 15 to rise, so that the outer surface of the guide roller 15 is in contact with the bottom plane of the prefabricated PK plate, the prefabricated PK plate is pushed to extend inwardly through the tangential pushing force, and slides along the guide assembly 12.

[0045] Due to the beam spacing problem, the bottom of the prefabricated PK plate cannot be provided with a corresponding supporting device during installation, so that the embodiment is provided with the adsorption assembly 17 on the guide assembly 12, so as to form an adsorption force on the upper plane of the prefabricated PK plate, along with the sliding of the prefabricated PK plate along the guide assembly 12, the air flow of the adsorption assembly 17 is disconnected after the prefabricated PK plate is installed, so that the prefabricated PK plate is separated from the adsorption assembly 17.

[0046] The embodiment is convenient and simple in overall operation, can effectively guide the prefabricated PK plate, and drives the prefabricated PK plate to stably slide into the installation gap of the two-layer steel structure frame, through the use of the adsorption assembly 17, the prefabricated PK plate is positioned during sliding, so as to effectively avoid deviation during movement, and ensure the accuracy of the installation of the prefabricated PK plate.

[0047] In one case of the embodiment,

[0048] Please refer to Figure 2 , the inner edge of the feeding frame 16 is provided with an inner limiting frame 61, and the inner frame of the inner limiting frame 61 is provided with a sliding roller 62; for the prefabricated PK plate of the profile structure, the embodiment is designed to be provided with the sliding roller 62 on both sides of the feeding frame 16, so as to facilitate the introduction of the prefabricated PK plate of the profile structure.

[0049] In one case of the embodiment,

[0050] Please refer to Figure 2 , the ceiling rack 13 is provided with a fixed horizontal plate 65, the fixed horizontal plate 65 is provided with a plurality of ceiling bolts 66, the fixed horizontal plate 65 and the supporting frame 21 are provided with a triangular supporting rack 63, and the triangular supporting rack 63 and the fixed horizontal plate 65 are further provided with an inclined reinforcing bolt 64.

[0051] For the ceiling frame 13, the fixed horizontal plate 65 is designed in this embodiment as an external installation mechanism. A triangular support frame 63 is set between the fixed horizontal plate 65 and the support frame 21 to form an outer triangular stable structure, and an oblique reinforcement bolt 64 is set between the triangular support frame 63 and the fixed horizontal plate 65 to form an inner triangular stable structure, thereby improving the overall stability.

[0052] In one embodiment;

[0053] For the adsorption component 17, this embodiment designs the following technical structure:

[0054] See also Figure 3 The guide component 12 includes a support frame 21, and a guide track 22 is provided on the inner side of the support frame 21. The main body of the adsorption component 17 is an adsorption substrate 23, and the adsorption substrate 23 is installed in the guide track 22. A plurality of adsorption heads 26 are installed on the adsorption surface of the adsorption substrate 23; the adsorption substrate 23 is externally connected to an airflow duct 29.

[0055] The adsorption substrate 23 slides along the guide rail 22. The adsorption substrate 23 has a built-in vacuum chamber. The adsorption head 26 adopts a suction cup structure. The gas is extracted through the air flow duct 29 to generate negative pressure, so that the prefabricated PK board is adsorbed and adhered to the adsorption surface of the adsorption substrate 23.

[0056] See also Figure 3 and Figure 4 , positioning frames 27 are provided at both ends of the support frame 21, and the inner frame of the positioning frame 27 is provided with a plurality of locking heads 28, and a guide rod 25 is provided between the locking heads 28 at both ends. The adsorption base plate 23 is provided with a corresponding sliding sleeve 24, and the sliding sleeve 24 is sleeved on the corresponding guide rod 25.

[0057] In order to ensure that the adsorption substrate 23 maintains consistency with the prefabricated PK board, the present application designs a plurality of sliding sleeves 24 to be provided on the adsorption substrate 23. The sliding sleeves 24 slide along the guide rods 25, so that the adsorption substrate 23 and the prefabricated PK board slide synchronously.

[0058] The support frame 21 also includes a recovery roller 51, which is wrapped with a pull rope 52 and connected to the adsorption substrate 23. The adsorption substrate 23 is connected to the recovery roller 51 via the pull rope 52. After the prefabricated PK board is separated from the adsorption substrate 23, the recovery roller 51 is driven by a motor, thereby driving the adsorption substrate 23 to pull it back to its initial position.

[0059] In one embodiment;

[0060] See also Figure 5The supporting base frame 14 includes a mounting frame 31, a fixed seat 32 arranged at the bottom of the inner cavity of the mounting frame 31, and a lifting frame 35 mounted on the fixed seat 32. A mounting seat 33 is installed on the top of the lifting frame 35, and the guide roller 15 is installed on the mounting seat 33.

[0061] In this embodiment, the guide roller 15 is installed above the supporting base 14 through the lifting frame 35. When the prefabricated PK board is loaded, the lifting frame 35 pushes the guide roller 15 to fit the board surface of the prefabricated PK board, thereby effectively adapting to prefabricated PK boards of different thicknesses.

[0062] As for the specific implementation structure of the lifting frame 35, the lifting frame 35 of this embodiment is designed to adopt a folding lifting rod structure. The mounting frame 31 has a built-in driver 36. The driving end of the driver 36 is installed with a driving screw 34. The driving screw 34 drives the folding rod of the lifting frame 35 to open and close.

[0063] The driving screw 34 is driven to move by the driver 36, thereby driving the folding rod of the lifting frame 35 to push the mounting seat 33 to move upward, and then push the guide roller 15 to fit onto the board surface of the prefabricated PK board.

[0064] Preferably, a lifting track 37 is provided on the shelf of the installation frame 31 , and the installation seat 33 is limited in the lifting track 37 to limit the lifting of the installation seat 33 .

[0065] Preferably, both the fixing seat 32 and the mounting seat 33 are provided with a sliding rail 38 , and the mounting seat 33 is provided with a sliding ball 39 . The sliding ball 39 is embedded in the sliding rail 38 to limit the opening and closing of the folding rod on the lifting frame 35 .

[0066] In one embodiment;

[0067] Regarding the driving method for driving the prefabricated PK board to move, this embodiment designs the following structure:

[0068] See also Figure 6 The guide roller 15 includes side wing plates 41 arranged on both sides of the guide roller 15, a driving roller 42 installed between the side wing plates 41, and a steering roller body 43 installed on the driving roller 42, and a plurality of toggle components 44 are installed on the outer roller surface of the steering roller body 43.

[0069] See also Figure 7The toggle assembly 44 includes a fixed end 45 mounted on the outer roller surface of the steering roller body 43, and a toggle plate 46 mounted on the fixed end 45 through a movable shaft. A telescopic support rod 47 is also provided on the outer roller surface of the steering roller body 43, and an insert sleeve 48 is provided on the plate surface of the toggle plate 46. The telescopic end of the telescopic support rod 47 is inserted into the insert sleeve 48 and an extrusion spring 49 is connected to the insert sleeve 48.

[0070] In this embodiment, the driving roller 42 is driven to rotate by a motor, thereby driving the steering roller body 43 to move. The toggle plate 46 on the steering roller body 43 contacts the bottom plane of the prefabricated PK plate. The prefabricated PK plate forms an extrusion force on the toggle plate 46, pushing the toggle plate 46 to bend, that is, compressing the extrusion spring 49. The extrusion spring 49 provides a reverse elastic force, thereby pushing the prefabricated PK plate to move. During the movement of the steering roller body 43, each toggle assembly 44 alternately provides elastic force to the prefabricated PK plate, thereby pushing the prefabricated PK plate to continue to move. At the same time, since the toggle plate 46 is bendable, it will not form spatial interference with the prefabricated PK plate, so that the toggle plate 46 will not rub against the prefabricated PK plate, thereby avoiding the risk of wear of the prefabricated PK plate.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
