Description

Technical Field

[0001] This utility model belongs to the technical field of material handling equipment, specifically relating to a transfer device for the production of marine waterproof membrane. Background Technology

[0002] The transfer device used in the production of marine waterproof membrane is an indispensable auxiliary equipment in the marine waterproof membrane production process. It is mainly used to transfer semi-finished or finished waterproof membranes between different processes in the workshop. Through the cooperation of the load-bearing structure and the moving parts, the waterproof membranes can be transferred efficiently and conveniently, ensuring the continuity of the production process.

[0003] However, existing transfer devices used in the production of marine waterproof membranes have some problems in practical applications. Specifically, since marine waterproof membranes are mostly large-sized sheets, and different quantities of sheets need to be transferred frequently during the production process, the placement area of ​​traditional transfer devices is fixed, making it difficult to flexibly adapt to diverse transfer needs. When a small number of sheets need to be transferred, the fixed-area device will cause space waste and increase the equipment's footprint in the workshop. When faced with large batches or extra-wide waterproof membranes, insufficient placement area will force multiple transfers, which not only reduces production efficiency but also increases labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a transfer device for the production of marine waterproof membranes, in order to solve the problems mentioned in the background art, which are mostly large-sized sheets that need to be frequently transferred in different quantities. Traditional transfer devices are difficult to adapt to diverse needs due to their fixed placement area. They also waste space and increase workshop area when transferring a small number of sheets. When dealing with large batches or extra-wide sheets, multiple transfers are required due to insufficient area, which reduces efficiency and increases labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for the production of marine waterproof membrane, comprising a load-bearing metal base frame and a metal placement plate disposed on the top of the load-bearing metal base frame, wherein the metal placement plate is fixedly connected to the load-bearing metal base frame by welding, the metal placement plate is flush with the outer walls of the load-bearing metal base frame, and the load-bearing metal base frame is provided with movable wheels near the four corners at the bottom end, and the load-bearing metal base frame is provided with expandable placement devices in the front and rear halves of the bottom.

[0006] Preferably, the expandable placement device at the bottom of the front half of the load-bearing metal base frame includes a rectangular storage cover and a rectangular expansion placement plate. The rectangular storage cover is welded and fixed to the outer wall of the bottom of the front half of the load-bearing metal base frame. The front end of the rectangular storage cover is open, and the rectangular expansion placement plate is inserted into the inside of the rectangular storage cover.

[0007] Preferably, the expandable placement device further includes a T-shaped fixing slot and a T-shaped fixing block. The rectangular expandable placement plate is provided with a T-shaped fixing block at the center of its rear end and on its left and right sides. The metal placement plate is connected to the center of its front end and on its left and right sides of the load-bearing metal base frame with a T-shaped fixing slot. The top of the T-shaped fixing slot is open.

[0008] Preferably, the rectangular expansion placement plate is hollow inside, while the T-shaped fixing block is a solid metal block inside. After the T-shaped fixing block is fully inserted into the T-shaped fixing slot from top to bottom, the rectangular expansion placement plate is flush with the top outer wall of the metal placement plate.

[0009] Preferably, the expandable placement device further includes adjusting screw holes and hand-tightened anti-detachment screws. The rectangular storage cover has adjusting screw holes near the front opening and inside the left and right ends. Each of the two adjusting screw holes is threaded with a hand-tightened anti-detachment screw. After the hand-tightened anti-detachment screw is tightened, the screw rod is blocked inside the left and right ends of the front opening of the rectangular storage cover to prevent the rectangular expansion placement plate inside the rectangular storage cover from sliding outward.

[0010] Preferably, the expandable placement device further includes a pull-out handle, which is welded to the center of the front end of the rectangular expandable placement plate. The pull-out handle can be used to pull the rectangular expandable placement plate into the interior of the rectangular storage cover, or to pull out the rectangular expandable placement plate placed inside the rectangular storage cover.

[0011] Preferably, the load-bearing metal base frame is fixedly connected to the four bottom casters by multiple screws, and the casters are all omnidirectional wheels with built-in brakes. The casters do not contact the outer wall of the rectangular storage cover when rotating 360 degrees.

[0012] Preferably, a left U-shaped movable handrail is welded to the top left end of the metal placement plate, and a right U-shaped movable handrail is welded to the top right end of the metal placement plate. Both the left and right U-shaped movable handrails have their U-shaped openings facing downwards, and the corners at the front and rear ends of the top of the left and right U-shaped movable handrails are treated with a large-radius arc surface passivation.

[0013] Preferably, both the left and right U-shaped movable handrails have welded reinforcing strips inside their bottom openings, and both reinforcing strips are fixedly connected to the metal placement plate by welding. Both the left and right U-shaped movable handrails have multiple metal reinforcing rods connected at equal intervals inside their U-shapes.

[0014] Compared with the prior art, this utility model provides a transfer device for the production of marine waterproof membrane, which has the following beneficial effects:

[0015] This invention adds a novel expandable placement device to both the front and rear halves of the bottom of a load-bearing metal frame. After the expandable placement device is put into use, the placement area can be expanded, improving space utilization. The device uses the pull-out cooperation of a rectangular expansion placement plate and a rectangular storage cover to form additional load-bearing areas at the front and rear ends of the metal placement plate. When a large amount of marine waterproof board or large-sized materials need to be transported, the rectangular expansion placement plate can be pulled out and precisely connected with the T-shaped fixing block and the T-shaped fixing slot, which can expand the overall placement area to many times that of the original metal placement plate. This solves the problem of small single transport volume and frequent round trips caused by the fixed area limitation of traditional transfer devices, and greatly improves the overall efficiency of material transfer.

[0016] Secondly, the device is easy and flexible to operate, adapting to diverse transportation needs. The pull-out handle allows for easy removal and retraction of the rectangular expansion plate. Combined with the quick-locking and unlocking design of the hand-tightened anti-loosening screws, the device can be fixed in the expanded state or limited in the retracted state without the need for professional tools. This design allows the device to flexibly adjust the placement space according to the quantity and size of the marine waterproofing panels. For example, the expansion plate can be retracted when transporting small batches or small panels, reducing the space occupied by the device. Conversely, the expansion plate can be unfolded when transporting large batches or large panels to meet high-capacity load-bearing requirements, demonstrating strong adaptability. Furthermore, the device has a stable and reliable structure, ensuring safety during transportation. The T-shaped fixing blocks and T-shaped fixing slots are precisely sized, ensuring that the rectangular expansion plate is flush with the top outer wall of the metal plate after insertion, forming a continuous and flat bearing surface. This prevents the panels from tilting and slipping due to height differences. Simultaneously, the hollow design inside the rectangular expansion plate reduces its weight while the solid metal structure of the T-shaped fixing blocks ensures the bearing strength of key stress points, stably supporting heavy objects such as marine waterproofing panels.

[0023] 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.

[0024] This utility model provides, for example Figure 1-5 The illustrated transfer device for marine waterproof membrane production includes a load-bearing metal base frame 2 and a metal placement plate 3 mounted on top of the load-bearing metal base frame 2. The metal placement plate 3 and the load-bearing metal base frame 2 are fixedly connected by welding, forming a rigid integral structure that effectively distributes the pressure generated during the placement of the marine waterproof membrane, preventing excessive local stress and deformation, and improving the overall load-bearing capacity. The metal placement plate 3 and the outer walls of the load-bearing metal base frame 2 are flush on all four sides. This flush design reduces collisions with surrounding objects during transfer, lowers safety hazards caused by protruding structures, and facilitates flexible movement in confined spaces. The load-bearing metal base frame 2 is equipped with casters 1 near the four corners at its bottom. The metal base frame 2 is fixedly connected to the four bottom casters 1 by multiple screws. The multiple screws enhance the stability of the connection between the casters 1 and the base frame, preventing the wheels from loosening when carrying heavy objects and ensuring the smoothness of the transfer process. All the casters 1 are omnidirectional wheels with built-in brakes. The built-in brakes can fix the device when loading and unloading marine waterproof panels to prevent slippage. The omnidirectional wheel design allows the device to turn 360 degrees flexibly, making it easy to adjust the direction of travel in the complex environment of the production workshop. When the casters 1 rotate 360 ​​degrees, they do not contact the outer wall of the rectangular storage cover 10. This positional design avoids mutual interference between the casters 1 and the rectangular storage cover 10, ensuring that the casters 1 rotate without obstruction and ensuring the mobility of the device.

[0025] like Figure 1 and Figure 2As shown, a left U-shaped movable handrail 5 is welded to the top left end of the metal placement plate 3, and a right U-shaped movable handrail 7 is welded to the top right end of the metal placement plate 3. Both the left U-shaped movable handrail 5 and the right U-shaped movable handrail 7 have their U-shaped openings facing downwards. This downward-facing U-shaped opening design conforms to ergonomic principles, making it more comfortable for operators to hold when pushing the handrail and effectively reducing fatigue caused by prolonged operation. The corners at the top front and rear ends of the left U-shaped movable handrail 5 and the right U-shaped movable handrail 7 are all treated with a large-radius arc surface passivation treatment. This passivation treatment removes sharp parts at the corners, preventing operators from being scratched during use and improving operational safety. Both the movable handrail 5 and the right U-shaped movable handrail 7 have welded reinforcing strips 6 welded inside their bottom openings. Both reinforcing strips 6 are fixedly connected to the metal placement plate 3 by welding. The welded reinforcing strips 6 increase the connection area between the handrail and the metal placement plate 3, allowing the force to be transferred to the placement plate more evenly when the handrail is under stress, thereby enhancing the load-bearing strength of the handrail and preventing it from breaking due to excessive force. Both the left U-shaped movable handrail 5 and the right U-shaped movable handrail 7 have multiple metal reinforcing rods 8 connected at equal intervals inside their U-shapes. The metal reinforcing rods 8 provide support and can improve the handrail's resistance to deformation, ensuring the stability of the handrail structure when pushed by multiple people at the same time or when encountering bumps.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the load-bearing metal base frame 2 has expandable placement devices 4 in both the front and rear halves of its bottom. The expandable placement device 4 in the bottom of the front half of the load-bearing metal base frame 2 includes a rectangular storage cover 10 and a rectangular expansion plate 11. The rectangular storage cover 10 is welded and fixed to the outer wall of the bottom of the front half of the load-bearing metal base frame 2. The rectangular storage cover 10 provides storage space for the rectangular expansion plate 11. The welding method ensures the structural stability of the storage cover during device movement and load-bearing. The front end of the rectangular storage cover 10 is open, and the rectangular expansion plate 11 is inserted inside the rectangular storage cover 10. The open design facilitates the pull-out operation of the rectangular expansion plate 11. The insertion and engagement method makes the storage and unfolding process of the expansion plate smoother, while ensuring the stability of the expansion plate in the stored state. The expandable placement device 4 also includes a T-shaped fixing slot 13 and a T-shaped fixing block 15. T-shaped fixing blocks 15 are provided at the center of the rear end of the rectangular expansion plate 11 and on its left and right sides. The placement plate 3 and the load-bearing metal base frame 2 are connected to T-shaped fixing slots 13 at the center of the front end and on both sides. The top of the T-shaped fixing slot 13 is open. The T-shaped fixing block cooperates with the slot, which provides better lateral limiting effect compared with the ordinary straight insertion structure, preventing the rectangular expansion placement plate 11 from swaying left and right when under load. The rectangular expansion placement plate 11 is hollow inside, while the T-shaped fixing block 15 is a solid metal block inside. The hollow interior of the rectangular expansion placement plate 11 can reduce its own weight, facilitate the pull-out operation, and save materials. The T-shaped fixing block 15 is a solid metal block, which ensures the strength of the connection part and can withstand the weight pressure of the marine waterproof plate. After the T-shaped fixing block 15 is fully inserted into the T-shaped fixing slot 13 from top to bottom, the rectangular expansion placement plate 11 is flush with the top outer wall of the metal placement plate 3. The flush design keeps the placement surface continuous and flat, avoiding the marine waterproof plate from slipping due to height difference, and ensuring the safety of the transportation process.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the expandable placement device 4 also includes adjusting screw holes 9 and hand-tightened anti-detachment screws 14. Adjusting screw holes 9 are provided near the front opening of the rectangular storage cover 10, both inside the left and right ends. Hand-tightened anti-detachment screws 14 are threaded into both adjusting screw holes 9. After tightening the hand-tightened anti-detachment screws 14, the screws block the left and right ends of the front opening of the rectangular storage cover 10, preventing the rectangular expandable placement plate 11 inside the rectangular storage cover 10 from sliding outwards. The hand-tightened anti-detachment screws 14 can be operated without tools, making it convenient and quick. When the plate 11 is stored, it can effectively prevent it from accidentally sliding out due to vibration or other reasons, thus improving the safety of the device. The expandable placement device 4 also includes a pull-out handle 12, which is welded to the center of the front end of the rectangular expandable placement plate 11. The pull-out handle 12 can be used to pull the rectangular expandable placement plate 11 into the interior of the rectangular storage cover 10, or to pull the rectangular expandable placement plate 11 placed inside the rectangular storage cover 10 outward. The pull-out handle 12 provides a convenient point of force for the operator, making the pulling operation of the rectangular expandable placement plate 11 easier and improving work efficiency.
