Abstract
Description
Technical Field
[0001] A gypsum board transfer cart suitable for narrow spaces relates to the field of building construction, and more specifically, to an auxiliary tool for prefabricated buildings that includes lightweight partitions made of modified gypsum board. Background Technology
[0002] In prefabricated buildings, lightweight partition walls are an essential design unit for improving assembly efficiency. Modified gypsum board, due to its excellent performance parameters (including its light weight), occupies a significant share among lightweight partition wall materials. However, it also has the drawback of low hardness, which makes the edges and corners of modified gypsum board easily damaged during transportation, especially in narrow alleys or elevators on construction sites. Furthermore, due to the large size of modified gypsum board, facilitating transportation without damaging the edges and corners is a major factor restricting its application. Chinese Patent No. ZL202222301379.2 discloses a transfer device for gypsum board production, including a base plate 1, a support plate 2, and a support plate 3. A partition plate 4 is provided above the support plate 3, and a movable seat 5 is spaced apart at the lower end of each partition plate 4. A first sliding groove is parallel to the support plate 3, and the movable seat 5 is disposed within the first sliding groove. A fixing plate 6 is fixed to one end of the support plate 2, and a strip-shaped through groove is provided on the fixing plate 6. A sliding element 7 is disposed within the strip-shaped through groove. A second sliding groove is provided in the middle of the bottom surface of the support plate 2, and a movable element 9 is disposed within the second sliding groove. Two adjacent partition plates 4 are parallel to each other and respectively contact the two ends of the gypsum board, separating the gypsum board from each other. This gypsum board transfer device is only suitable for transfer during the production process and is not suitable for transfer of gypsum boards in narrow spaces during construction. Utility Model Content
[0003] The technical problem this utility model aims to solve is to provide a transfer trolley that prevents damage to modified gypsum board when transporting it in narrow alleyways or elevators at construction sites, addressing the above-mentioned shortcomings. The technical solution is as follows:
[0004] A plasterboard transfer cart suitable for narrow spaces, its key technology lies in including a load-bearing structure and a protective structure. The load-bearing structure includes a load-bearing bracket and steering wheels. The load-bearing bracket is mounted on the steering wheels via a rotating shaft. X-shaped brackets are installed on the load-bearing brackets located on both sides of the rotating shaft. Lateral expansion joints are installed at both ends of the load-bearing brackets. The protective structure consists of a parallel vertical bracket installed on one side of the middle position of the load-bearing bracket. A vertical expansion joint is installed at the upper end of the vertical bracket. A lateral bracket is installed between the two vertical brackets. Anti-tipping hooks are installed at the top of the two vertical brackets.
[0005] Install rubber gaskets at the ends of the transverse expansion joints.
[0006] Compared with the prior art, the present invention has the following beneficial effects:
[0007] 1. The horizontal and vertical expansion joints can be adjusted according to the size of the modified gypsum board to meet the actual construction conditions on site. Suitable for the transport of single gypsum boards, it occupies only the volume of a single modified gypsum board, making it well-suited for narrow alleyways and confined spaces in construction sites and construction elevators.
[0008] 2. The X-shaped bracket is designed to protect the sides of the plasterboard placed on it.
[0009] 3. The rubber gaskets fixed at the ends of the transverse expansion joints can ensure that the edges and corners of the modified gypsum board are not damaged by collisions during transportation.
[0010] 4. Vertical supports and anti-tipping hooks can fix the modified gypsum board during transportation, ensuring that the modified gypsum board does not tip over during transportation.
[0011] 5. Install steering wheels in the middle of the trolley to allow for flexible turning of the trolley as needed during transport.
[0012] 6. Install a vertical support on one side of the load-bearing bracket to facilitate the loading and unloading of gypsum board. Attached Figure Description

[0017] Reference Figures 1-4A gypsum board transfer trolley suitable for confined spaces is disclosed. Its key technologies include a load-bearing structure and a protective structure. The load-bearing structure comprises a load-bearing bracket 8 and steering wheels 1. The load-bearing bracket 8 is mounted on the steering wheels 1 via a rotating shaft 9, with the steering wheels 1 located in the middle of the load-bearing bracket 8. The load-bearing bracket 8 is constructed of angle steel welded into a rectangular frame structure. X-shaped brackets 10 are installed on the load-bearing bracket 8 on both sides of the rotating shaft 9, and transverse expansion joints 7 are installed at both ends of the load-bearing bracket 8. The protective structure consists of two parallel vertical brackets 3 installed on one side of the middle position of the load-bearing bracket 8. Vertical expansion joints 4 are installed at the upper end of the vertical brackets 3, and a transverse bracket 6 is installed between the two vertical brackets 3. Anti-tipping hooks 5 are installed at the top of the two vertical brackets 3. During use, the other end of the anti-tipping hook 5 is fixed to the side wall of the gypsum board to ensure that the modified gypsum board does not tip over during transport. The protective structure is constructed of galvanized steel pipes. The transverse expansion joints 7 and vertical expansion joints 4 adopt an inner and outer sleeve structure, allowing the inner tube to slide and expand freely within the outer tube.
[0018] Installing rubber gaskets 2 at the end of the transverse expansion joint 7 ensures that the edges and corners of the modified gypsum board are not damaged by collisions during transportation.
[0019] During construction, workers adjust the length and height of the device using the horizontal expansion joint 7 and vertical expansion joint 4 to accommodate the dimensions of the modified gypsum board, based on its length and width. A modified gypsum board is placed on the load-bearing bracket 8 using other devices, and then the horizontal and vertical expansion joints 7 and 4 are adjusted to fit the board snugly. During transport, workers can control the forward movement of the modified gypsum board by holding it by hand. The steering wheel 1 rotates flexibly according to site requirements during transport, making it particularly suitable for transporting modified gypsum boards in narrow alleyways or elevators in construction sites.
