After the above structure is adopted, the novel cart realizes direct carrying of the plate from transportation to the installation position without turning over, greatly reduces the manual operation strength, and improves the operation efficiency and the plate protection level.

Description

Technical Field

[0001] This invention relates to the field of building decoration transportation equipment technology, specifically a combined frame type panel material trolley that facilitates transportation to a workbench. Background Technology

[0002] With the development of the building decoration industry, the transportation and installation of many building materials are becoming increasingly frequent. The current method of transporting building materials involves stacking them flat on traditional trailers and dragging them to the installation area on the workbench. Since the workbench is usually higher than the trailer, the materials often need to be manually moved from the trailer to the workbench and rotated from a horizontal to a vertical position for installation. This method is labor-intensive, inefficient, and prone to damage during handling and rotation. Therefore, improving existing trolleys to facilitate material handling, delivering materials to their designated positions on the workbench in one go, reducing the rotation process, minimizing manual labor, and increasing work efficiency are problems that need to be addressed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the above-mentioned situation by proposing a combined frame material trolley that reduces manual operation, increases work efficiency, and facilitates transportation to the workbench.

[0004] To achieve the above objectives, the technical solution of this invention is: a combined frame type sheet material trolley, comprising: a bottom trailer, a top trailer, and a sheet support frame, wherein,

[0005] The bottom trailer includes: a left parallel keel, a right parallel keel, an upper transverse keel, a lower transverse keel, four bottom roller assemblies, a left side panel, a right side panel, an upper side panel, and a lower movable side panel. The left parallel keel, right parallel keel, upper transverse keel, and lower transverse keel are welded to form a bottom horizontal frame. The four bottom roller assemblies are fixedly connected to the four corners of the bottom horizontal frame. The left side panel, right side panel, and upper side panel are vertically welded to the edges of the corresponding left parallel keel, right parallel keel, and upper transverse keel, respectively. The lower movable side panel is connected to the lower transverse keel by a hinged hinge.

[0006] The top trailer includes: a top horizontal frame welded from several profiles, and four top roller assemblies, which are respectively installed at the four corners of the top horizontal frame;

[0007] The sheet metal support includes: several angled supports welded together from inclined keels, with the bottom of the sheet metal support fixedly connected to the top horizontal frame of the top trailer;

[0008] During assembly, the four top roller assemblies of the top trailer are adapted to the left and right parallel keels of the bottom trailer. The top trailer slides into the corresponding left and right parallel keels through the entrance of the lower movable baffle via the four top roller assemblies and slides into place. After the top trailer is suspended on the bottom trailer, the lower movable baffle flips up to cover and position it to prevent the top trailer from sliding out.

[0009] Several supporting transverse keels are also welded between the left and right parallel keels at intervals.

[0010] The lower movable enclosure is provided with pin sleeves at both ends and at corresponding positions of the left and right enclosures. After assembly, the left U-shaped pin is inserted into the pin sleeve of the left enclosure and the left side pin sleeve of the lower movable enclosure, and the right U-shaped pin is inserted into the pin sleeve of the right enclosure and the right side pin sleeve of the lower movable enclosure.

[0011] The bottom roller assembly includes a roller column, a roller, and a roller shaft connector. The roller is mounted on the bottom of the roller column via the roller shaft connector, and the top of the roller column is welded to the four corners of the bottom horizontal frame.

[0012] The roller column consists of interlocking round tubes that can be adjusted in height and positioning pins.

[0013] The top roller assembly includes a top roller, a top roller shaft connector, and a connecting plate. The top roller is fixed to the four corners of the top horizontal frame through the top roller shaft connector and the connecting plate.

[0014] The top horizontal frame includes four square frame keels and an internal structural frame.

[0015] The angled bracket has an umbrella-shaped cross-section. The middle of the angled bracket is a vertical support frame, the front side of the vertical support frame is an inclined plate-shaped material support frame, and the rear side of the vertical support frame is an inclined support frame.

[0016] All the keels of the bottom trailer, top trailer, and plate support are made of square tubing.

[0017] By adopting the above structure, this new invention effectively solves the problems of low efficiency and easy damage caused by the need for manual secondary handling and flipping in traditional sheet material transportation through the combination of bottom trailer, top trailer and corner bracket.

[0018] It has the following characteristics:

[0019] 1. Reduced manual handling and flipping processes: The unique umbrella-shaped bracket, welded from inclined keel, keeps the panels in a near-vertical tilt state required for installation during transportation; when the bottom trolley moves to the workbench, the adjustable bottom roller assembly can easily raise the top trolley to the workbench height and push it onto the workbench to the installation position. The panels can be directly moved from the bracket to the installation position, eliminating the manual flipping step from horizontal to vertical, significantly reducing labor intensity and the risk of bumps and knocks.

[0020] 2. Improved loading and unloading efficiency and stability: The top trailer slides onto the left and right parallel keels of the bottom trailer via the top roller assembly. Combined with the quick-locking structure of the lower movable baffle and U-shaped pin, the top trailer can be quickly slid in, accurately positioned, and safely locked. The loading and unloading process is smooth and simple and prevents slippage. The supporting transverse keels inside the bottom frame further enhance the overall load-bearing stability and prevent the plates from sinking and deforming.

[0021] 3. Stable structure and strong adaptability: The whole structure adopts a square tube keel welded frame structure, combined with a double-layer support design of bottom horizontal frame and top horizontal frame, as well as three fixed baffles and movable baffles on the bottom frame, which provides stable support and lateral protection for tilted plates; the adjustable height of the rollers allows the trolley to flexibly adapt to workbenches of different heights, ensuring seamless connection between transportation and installation.

[0022] In summary, this new type of trolley enables direct, non-tumbling transport of sheet materials from the transportation location to the installation position, significantly reducing the intensity of manual operation and improving work efficiency and the level of sheet material protection.

[0032] The following is in conjunction with the appendix Figure 1-9 The specific embodiments of this novel invention will be described in further detail.

[0033] This embodiment is a combined frame type sheet material trolley, including: a bottom trailer 10, a top trailer 20, and a sheet support 30, wherein...

[0034] The bottom trailer 10 includes: a left parallel keel 11, a right parallel keel 12, an upper transverse keel 13, a lower transverse keel 14, four bottom roller assemblies 15, a left side panel 16, a right side panel 17, an upper side panel 18, and a lower movable side panel 19. The left parallel keel 11, the right parallel keel 12, the upper transverse keel 13, and the lower transverse keel 14 are welded to form a bottom horizontal frame. The four bottom roller assemblies 15 are fixedly connected to the four corners of the bottom horizontal frame. The left side panel 16, the right side panel 17, and the upper side panel 18 are vertically welded to the edges of the corresponding left parallel keel 11, the right parallel keel 12, and the upper transverse keel 13, respectively. The lower movable side panel 19 is movably flipped and connected to the lower transverse keel 14 via a hinge 191.

[0035] The top trailer 20 includes: a top horizontal frame 21 welded from several profiles, and four top roller assemblies 22, which are respectively installed at the four corners of the top horizontal frame 21;

[0036] The plate support 30 includes: a number of angled supports 31 welded together from inclined keels, the bottom of which is fixedly connected to the top horizontal frame 21 of the top trailer 20;

[0037] During assembly, the four top roller assemblies 22 of the top trailer 20 are adapted to the left parallel keel 11 and right parallel keel 12 of the bottom trailer 10. The top trailer 20 slides into the corresponding left parallel keel 11 and right parallel keel 12 through the entrance of the lower movable baffle 19 via the four top roller assemblies 22 and slides into place. After the top trailer 20 is suspended on the bottom trailer 10, the lower movable baffle 19 flips to cover and position it to prevent the top trailer 20 from sliding out.

[0038] Several supporting transverse keels 111 are also welded at intervals between the left parallel keel 11 and the right parallel keel 12.

[0039] The lower movable baffle 19 has a left pin sleeve 192 and a right pin sleeve 193 at the corresponding positions of the left baffle 16 and the right baffle 17. After assembly, the left U-shaped pin 41 is inserted into the pin sleeve of the left baffle 16 and the left pin sleeve 192 of the lower movable baffle 19, and the right U-shaped pin 42 is inserted into the pin sleeve of the right baffle 17 and the right pin sleeve 193 of the lower movable baffle 19.

[0040] like Figure 2 As shown in the embodiment, the bottom roller assembly 15 includes a roller column 151, a roller 152 and a roller shaft connector 153. The roller 152 is mounted on the bottom of the roller column 151 through the roller shaft connector 153, and the top of the roller column 151 is welded to the four corners of the bottom horizontal frame.

[0041] like Figure 3 As shown in the embodiment, the roller column 151 is composed of interlocking round tubes 1511 with adjustable height and positioning pins 1512.

[0042] like Figure 4 As shown, the top roller assembly 22 includes a top roller 221, a top roller shaft connector 222, and a connecting plate 223. The top roller 221 is fixed to the four corners of the top horizontal frame through the top roller shaft connector 222 and the connecting plate 223.

[0043] The top horizontal frame 21 includes four square frame keels 211 and an internal structural frame 212.

[0044] The angled bracket has an umbrella-shaped cross-section. The middle of the plate bracket 30 is a vertical support frame 31, the front side of the vertical support frame is an inclined plate-shaped material support frame 32, and the rear side of the vertical support frame is an inclined support frame 33.

[0045] All the keels of the bottom trailer 10, top trailer 20, and plate support 30 are square tubes.

[0046] The usage process is as follows: First, adjust the height of the roller column 151 of the bottom trailer 10 according to the height of the target workbench 100, pull out the positioning pin 1512, adjust the height of the interlocking round tubes 1511 and then insert the positioning pin 1512 to fix it, so as to ensure that the top trailer 20 can be flush with the workbench 100 after it is raised.

[0047] Then, open the entrance: flip down the lower movable enclosure 19 to open it downwards, forming a sliding passage for the top trailer;

[0048] Next, load the boards: Place the building boards (such as gypsum board, calcium silicate board, etc.) at an angle on the board support 30. The umbrella-shaped structure of the board support 30 allows the boards to naturally maintain a near-vertical tilt state required for installation, without the need for manual flipping or adjustment.

[0049] During the process, the sides of the sheet are restricted by the left baffle 16 and the right baffle 17, and the upper end is blocked by the upper baffle 19 to prevent it from slipping or bumping during transportation, thus forming lateral protection.

[0050] Next, the top trailer 20 is slid in and locked: push the top trailer 20 so that its four top roller assemblies 22 at the bottom slide along the tracks of the left parallel keel 11 and right parallel keel 12 of the bottom trailer 20, slide in from the entrance of the open lower movable enclosure 19 until it is fully embedded in the frame of the bottom trailer 10.

[0051] Then close and lock the lower movable enclosure 19: flip the lower movable enclosure 19 upward to the vertical position to block the entrance, insert the left U-shaped pin 41 into the left enclosure pin sleeve 192, and insert the right U-shaped pin 42 into the corresponding right pin sleeve 193 to achieve mechanical locking and prevent the top trailer 20 from slipping off.

[0052] Next, the material is transported to the workbench 100: the bottom trailer 10 is pushed and moved to the target workbench 100 area by the four bottom roller assemblies 15 on its bottom. During the transportation process, the material is kept in a stable position by the tilted support, the horizontal keel 111 supports the material to prevent it from sinking and deforming, and the three-sided baffle provides lateral protection.

[0053] Finally, unloading and installation are carried out: the bottom trolley 10 is moved to the edge of the workbench 100, so that the top trolley 20 is aligned with the height of the workbench 100. The left and right U-shaped pins 41 and 42 are pulled out, the lower movable baffle 19 is flipped open, and the top trolley 20, together with the board support and the board, slides out along the left and right parallel keel 11 and 12 tracks and is pushed smoothly onto the surface of the workbench 100. The worker directly moves the board from the inclined support frame 32 of the board support 30 to the installation position and installs it on the wall. Because the board always maintains the required tilt angle for installation, the manual flipping step is eliminated, avoiding bumps and damage.

[0054] Once completed, return to the loading state: slide the empty top trailer 20 back to the bottom trailer 10 along the track, close and lock the lower movable enclosure 19, and then proceed with the next round of loading.

[0055] In actual use, transporting 20 1.2m×2.4m gypsum boards to a 0.5m workbench requires two people to move and flip them 40 times in the traditional way, taking 30 minutes and easily causing damage. With this new type of trolley, only one loading and one sliding transfer are needed. During installation, it can be moved horizontally without flipping, improving efficiency by more than 60% and causing zero damage to the boards.

[0056] Therefore, this new type of trolley enables direct, non-tumbling transport of sheet materials from transportation to installation location, significantly reducing the intensity of manual operation and improving work efficiency and the level of sheet material protection.

[0057] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on the utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
