Description

Technical Field

[0001] This utility model relates to the field of sheet material transportation technology, and in particular to sheet material racks. Background Technology

[0002] Currently, the shelving used in the storage of cement boards has many shortcomings. The existing shelving structure is fixed and cannot adapt to the storage needs of boards of different specifications. The space utilization rate is low, and the operation is inconvenient and inefficient when picking up and putting down boards, which can easily cause damage to the boards. In addition, traditional shelving lacks effective protection and management measures, which is not conducive to the long-term preservation and orderly management of the boards.

[0003] A search revealed Chinese Patent Publication No. CN211618671U, which discloses a sheet metal transport rack. The rack includes a base beam, a connecting plate, multiple clamping components, and multiple trapezoidal support components. One side of each support component is fixedly connected to the connecting plate, and the other side is fixedly connected to the base beam. Multiple base beams are arranged in parallel, with the length of each beam greater than the distance between the support components and the base beam connection points. Support rods for supporting the sheet metal are vertically fixedly connected between the base beams. The clamping components include multiple support modules on the connecting plate, a robotic arm assembly on each support module, and clamping arms. The clamping arms are respectively positioned facing both sides of the connecting plate along its length. The clamping arms are drive-connected to the robotic arm assembly, with one end rotatably connected to the support module. The robotic arm assembly drives the clamping arms to elastically press against the sheet metal. The cooperation between the robotic arm assembly and the clamping arms allows the sheet metal to be stably fixed on the rack, increasing its stability during transport. However, in actual use, since the sheet metal is made of cement, this device only meets the protection requirements during transport. Rainwater on the cement sheet metal can affect its quality and normal use, reducing the device's practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sheet material shelf, which aims to improve the problem that the existing technology can only fix the sheet material and cannot achieve waterproofing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sheet material shelf, including a base, with columns fixedly connected to the top four sides of the base, and a top plate fixedly connected to the top of multiple columns. A waterproof mechanism is provided on the outer wall of the top plate. A clamping mechanism is provided on the top of the base, and a drainage component is provided on the outer wall of the top plate. A positioning component is provided at the bottom of the base. The waterproof mechanism includes two waterproof plates, which are fixedly connected to the left and right sides of the top of the base. Mounting grooves are provided on the front and rear sides of the outer wall of the top plate, and the inner walls of the two mounting grooves are each provided with... The device includes two waterproof fabrics, one end of which is fixedly connected to the top of the inner wall of the corresponding mounting groove. The other end of each of the two waterproof fabrics is fixedly connected to a connecting rod. The left and right sides of the inner walls of the two mounting grooves are fixedly connected to retaining rings. The left and right sides of the outer walls of the two connecting rods are respectively engaged with the corresponding retaining rings. The front and rear sides of the outer wall of the base are provided with fixing grooves. The left and right sides of the inner walls of the two fixing grooves are rotatably connected to rotating rings. The top of the outer walls of the multiple rotating rings is provided with reserved holes. The left and right sides of the outer walls of the base are provided with sliding grooves. Fixing components are provided inside the multiple sliding grooves.

[0006] Through the above technical solution: When the shelving unit is in operation, the base serves as the basic support, bearing the weight of the shelving unit. The uprights are vertically fixed around the top of the base, providing stable support for the top plate. Regarding the waterproofing mechanism, the waterproof cloth is normally stored in the mounting groove, and the connecting rod engages with the retaining ring. When waterproofing is required, the connecting rod is removed from the retaining ring, and the waterproof cloth is spread along the mounting groove to cover the shelving unit. Then, the pull ring of the fixing component in the sliding groove is pulled, causing the insertion rod to move. The limiting ring compresses the spring, causing the insertion rod to slide out from the pre-drilled hole on the top of the rotating ring's outer wall. The rotating ring is then rotated out of the fixing groove, and the connecting rod is inserted. The rotating ring is rotated again to align the pre-drilled hole with the insertion rod. The pull ring is released, and under the spring force, the insertion rod inserts into the pre-drilled hole to fix the rotating ring, preventing the connecting rod from coming out. This, combined with the waterproof plates on the left and right sides of the top of the base, achieves waterproofing. Although the drainage component, clamping mechanism, and positioning component are not detailed here, it is presumed that they respectively serve the functions of drainage, fixing the shelving unit, and positioning the shelving unit.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes a baffle. An adjustment groove is provided on the top left side of the base. The bottom of the baffle is slidably connected to the inner wall of the adjustment groove. Multiple threaded holes are provided on the top left side of the base. Bolts are threadedly connected to the bottom left side of the baffle. The bolts are threadedly connected to the multiple threaded holes respectively. A guide groove is provided on the top right side of the base. A clamping plate is slidably connected to the inner wall of the guide groove. A lead screw is rotatably connected to the inner wall of the guide groove. The bottom of the clamping plate is threadedly connected to the lead screw.

[0009] The above technical solution involves adjusting the position of the baffle before placing the boards. Because there is an adjustment groove on the top left side of the base, the bottom of the baffle can slide freely within the groove. Based on the actual size of the boards and stacking requirements, the baffle can be slid into a suitable position within the adjustment groove. Then, using the multiple threaded holes on the top left side of the base, bolts are passed through the bottom left side of the baffle and screwed into the corresponding threaded holes, thus firmly fixing the baffle. The two vertical straight edges of the baffle facilitate neat stacking of the boards. After the boards are stacked, the screw is rotated. Since the screw is rotatably connected to the inner wall of the guide groove, and the bottom of the clamping plate is threadedly connected to the screw, according to the principle of threaded transmission, when the screw rotates, it will drive the clamping plate to slide left and right in the guide groove, causing the clamping plate to gradually approach and press against the boards, thus stabilizing and fixing the boards and preventing them from shaking.

[0010] As a further description of the above technical solution:

[0011] The fixing assembly includes multiple insert rods, the outer walls of the multiple insert rods are slidably connected to the inner walls of the corresponding sliding grooves, the middle of the outer walls of the multiple insert rods are slidably connected to limit rings, the outer walls of the multiple limit rings are fixedly connected to springs on opposite sides, the opposite ends of the multiple springs are fixedly connected to the corresponding sliding grooves, and the outer walls of the multiple insert rods are slidably connected to pull rings on opposite sides.

[0012] Through the above technical solution: when the fixed component is working, pulling the pull ring causes the insertion rod to slide in the sliding groove. The limiting ring moves accordingly and squeezes the spring, causing the insertion rod to slide out from the mating point, which can change the connection state of the relevant components. When the pull ring is released, the spring returns to its deformation, pushes the limiting ring and the insertion rod to reset, and the insertion rod is inserted into the corresponding position, thus fixing the components and playing a role in connection and positioning.

[0013] As a further description of the above technical solution:

[0014] The drainage assembly includes two inclined plates, with the outer walls of the two inclined plates fixedly connected to the front and rear sides of the outer wall of the top plate, respectively. Drainage grooves are provided on the top left and right sides of the top of the top plate and the two inclined plates.

[0015] Through the above technical solution: when the drainage component is working, rainwater falls onto the top plate and the inclined plate. The inclined plate is tilted, which guides the rainwater to flow to both sides. The drainage channels opened on the left and right sides of the top of the top plate and the inclined plate collect the rainwater guided by the inclined plate and discharge it, so as to avoid the rainwater accumulating on the top and causing damage to the plate.

[0016] As a further description of the above technical solution:

[0017] The positioning component includes a support frame, the top of which is fixedly connected to the bottom of the base. The bottom of the support frame is fixedly connected to four wheels. The left and right sides of the outer wall of the support frame are fixedly connected to fixing blocks. The inner walls of the fixing blocks are threaded with threaded rods, and the bottom ends of the threaded rods are rotatably connected to positioning seats.

[0018] The above technical solution involves a support frame connecting the base to the lower components, and casters that allow the shelf to move flexibly to a designated position. Once in position, rotating the threaded rod causes it to move up and down due to its threaded connection with the fixed block, which in turn moves the bottom positioning seat closer to the ground. When the positioning seat is pressed against the ground, the shelf is fixed, preventing it from moving arbitrarily.

[0019] As a further description of the above technical solution:

[0020] A soft pad is fixedly connected to the left side of the outer wall of the clamping plate, and multiple anti-slip grooves are opened on the upper and lower sides of the left end of the outer wall of the soft pad.

[0021] Through the above technical solution: when the clamping plate presses the board, the soft pad prevents the board from being damaged, and the anti-slip groove increases the friction, making the clamping plate more stable in fixing the board and preventing the board from sliding.

[0022] As a further description of the above technical solution:

[0023] A traction block is fixedly connected to the left side of the outer wall of the support frame, and a reserved hole is provided in the middle of the traction block.

[0024] With the above technical solution, when the shelf needs to be moved, ropes or other means can be passed through the reserved holes in the middle of the traction block to connect to external traction equipment, and the support frame can be pulled to move the shelf.

[0025] As a further description of the above technical solution:

[0026] A turntable is fixedly connected to the right end of the lead screw, and a handle is rotatably connected to the top right side of the outer wall of the turntable.

[0027] The above technical solution involves rotating the handle to rotate the turntable, which in turn causes the lead screw fixedly connected to the turntable to rotate, thereby enabling the movement of the clamping plate.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the waterproof function of the board is achieved through the cooperation of structures such as waterproof cloth, connecting rod, retaining ring, insert rod, limiting ring, spring, rotating ring and waterproof plate. Specifically, the waterproof cloth is first unfolded to cover the board, and then the connecting rod is fixed by the cooperation of the insert rod and the reserved hole of the rotating ring. The waterproof plate blocks the water flow, thereby improving the problem of the existing technology that can only fix the board and cannot achieve the waterproof function. It effectively protects the board from water damage and improves the safety and reliability of board storage.

[0030] 2. In this utility model, before placing the board, a sliding baffle can be installed in the adjustment groove according to the size of the board and the stacking requirements, and fixed with bolts and threaded holes. Its vertical straight edge helps the board to be stacked neatly. After the board is stacked, the screw is rotated, and the clamping plate is driven to slide and squeeze the board in the guide groove through the threaded transmission. This improves the problems of messy stacking and unstable fixing of the board that may exist in the prior art, and improves the utilization rate of storage space and the safety of board storage.

[0042] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a sheet material rack, including a base 1, which serves as the basic support component of the entire rack, providing an installation and load-bearing platform for other components. Uprights 4 are fixedly connected to the top of the base 1 on all four sides, providing vertical support and firmly supporting the upper structure. Multiple uprights 4 are fixedly connected to the top of a single top plate 5, providing some protection for the sheet materials stored inside.

A drainage component 6 is provided on the outer wall of the top plate 5, and a positioning component 7 is provided at the bottom of the base 1 to determine the rack's position and facilitate... Its movement and fixation; the waterproof mechanism 2 includes two waterproof plates 201, which are fixedly connected to the top left and right sides of the base 1 to block water flow from the left and right sides. The outer wall of the top plate 5 has mounting grooves 202 on both the front and back sides to provide installation and storage space for the waterproof cloth 203. The inner walls of both mounting grooves 202 are provided with waterproof cloth 203, which, when unfolded, can cover the board and block water falling from above. One end of each waterproof cloth 203 is fixedly connected to the top of the inner wall of the corresponding mounting groove 202, and the other end of each waterproof cloth 203 is fixedly connected to a connecting rod 204 for easy unfolding and fixing of the waterproof cloth 203. The inner walls of both mounting grooves 202 are fixedly connected with retaining rings 210 on the left and right sides. The left and right sides of the outer wall of the connecting rod 204 engage with corresponding retaining rings 210, facilitating the convenient storage of the waterproof cloth 203. The outer wall of the base 1 has fixing grooves 205 on both the front and rear sides, providing installation and rotation space for the rotating rings 206. Rotating rings 206 are rotatably connected to the left and right sides of the inner walls of the two fixing grooves 205 to cooperate in fixing the connecting rod 204. Pre-drilled holes 207 are provided at the top of the outer walls of the multiple rotating rings 206, which cooperate with the insertion rod 2091 to fix the rotating rings 206. Sliding grooves 208 are provided on the left and right sides of the outer wall of the base 1, providing a sliding track for the insertion rod 2091. Fixing components 209 are installed inside the multiple sliding grooves 208 to fix the rotating rings 206, thereby... The waterproof cloth 203 is fixed; the fixing component 209 includes multiple insert rods 2091, the outer walls of the multiple insert rods 2091 are slidably connected to the inner walls of the corresponding sliding grooves 208, for fixing the rotating ring 206, thereby fixing the waterproof cloth 203. The middle of the outer wall of the multiple insert rods 2091 is slidably connected to a limit ring 2092 to limit the sliding range of the insert rods 2091. The outer walls of the multiple limit rings 2092 are all fixedly connected to a spring 2093 on the side away from each other to limit the sliding range of the insert rods 2091. The ends of the multiple springs 2093 are fixedly connected to the corresponding sliding grooves 208. The outer walls of the multiple insert rods 2091 are all slidably connected to a pull ring 2094 on the side away from each other to facilitate the operator to pull the insert rods 2091.The drainage component 6 includes two inclined plates 601. The outer walls of the two inclined plates 601 are fixedly connected to the front and rear sides of the outer wall of the top plate 5 respectively. Drainage grooves 602 are provided on the top left and right sides of the top of the top plate 5 and the two inclined plates 601 to collect and discharge rainwater.

[0043] Specifically, regarding the waterproofing mechanism 2, waterproof plates 201 fixed to the left and right sides of the top of the base 1 block possible water flow from the sides. A waterproof cloth 203 is installed in the mounting grooves 202 on the front and rear sides of the outer wall of the top plate 5. One end of the cloth 203 is fixed to the top of the inner wall of the mounting groove 202, and the other end is connected to a connecting rod 204. Under normal conditions, the connecting rod 204 engages with the retaining rings 210 on the left and right sides of the inner wall of the mounting groove 202, and the waterproof cloth 203 is stored. When waterproofing is required, the connecting rod 204 is removed, and the waterproof cloth 203 is unfolded. At this time, the rotating ring 206 in the fixing grooves 205 on the front and rear sides of the outer wall of the base 1 rotates. The rotating ring 206 has a pre-drilled hole 207 on the top of its outer wall. The fixing components 209 in the sliding grooves 208 on the left and right sides of the outer wall of the base 1 function. The insert rod 2091 in the fixing component 209 is pulled by the pull ring 2094. Below, the limiting ring 2092 compresses the spring 2093, causing the insertion rod 2091 to slide out of the reserved hole 207. After rotating the rotating ring 206 to insert the connecting rod 204, it is rotated again to align the reserved hole 207 with the insertion rod 2091. The pull ring 2094 is released, and the spring 2093 pushes the insertion rod 2091 into the reserved hole 207 to fix the rotating ring 206, preventing the connecting rod 204 from coming out, thus achieving waterproofing. In the drainage component 6, the front and rear sides of the outer wall of the top plate 5 are respectively connected to the inclined plate 601. The drainage grooves 602 opened on the top left and right sides of the top of the top plate 5 and the inclined plate 601 guide rainwater into the drainage grooves 602 for discharge, assisting in waterproofing. Although the clamping mechanism 3 is not described in detail, it should be used for the sorting and fixing of the board. The positioning component 7 at the bottom of the base 1 is presumably used for shelf positioning. All components work together to meet the needs of board storage.

[0044] Reference Figure 4 , Figure 6 and Figure 7The clamping mechanism 3 includes a baffle 301, which guides the plates to be stacked neatly. An adjustment groove 302 is provided on the top left side of the base 1, providing sliding space for the baffle 301 to adjust its position. The bottom of the baffle 301 is slidably connected to the inner wall of the adjustment groove 302, allowing the baffle 301 to move flexibly within the adjustment groove 302. Multiple threaded holes 303 are provided on the top left side of the base 1, which cooperate with bolts 304 to fix the position of the baffle 301 within the adjustment groove 302. Bolts 304 are threadedly connected to the bottom left side of the baffle 301. Bolts 304 are threadedly connected to multiple threaded holes 303 respectively. A guide groove 305 is provided on the top right side of the base 1 to provide a guide path for the movement of the clamping plate 306. The clamping plate 306 is slidably connected to the inner wall of the guide groove 305 and slides in the guide groove 305 to squeeze and fix the plate. A lead screw 307 is rotatably connected to the inner wall of the guide groove 305. The bottom of the clamping plate 306 is threadedly connected to the lead screw 307, so that when the lead screw 307 rotates, it can drive the clamping plate 306 to slide left and right along the guide groove 305, thereby achieving clamping and fixing of the plate.

[0045] Specifically, the base 1 serves as the basic load-bearing component, providing installation positions for other components. The adjustment groove 302 on the top left side of the base 1 engages with the bottom of the baffle 301, allowing the baffle 301 to slide within the adjustment groove 302 for position adjustment. Simultaneously, multiple threaded holes 303 on the top left side of the base 1 engage with bolts 304 threaded to the bottom left side of the baffle 301. Once the baffle 301 has slid to the appropriate position, tightening the bolts 304 into the corresponding threaded holes 303 fixes the baffle 301 in place. This is achieved by utilizing the two vertical... The straight edges facilitate neat stacking of the boards. The guide groove 305 on the top right side of the base 1 has its inner wall slidably connected to the bottom of the clamping plate 306, which guides the movement of the clamping plate 306. The screw 307 rotatably connected to the inner wall of the guide groove 305 is threadedly connected to the bottom of the clamping plate 306. When the screw 307 rotates, according to the principle of thread transmission, it can drive the clamping plate 306 to slide left and right in the guide groove 305. After the boards are stacked, rotating the screw 307 causes the clamping plate 306 to move and squeeze the boards, thereby fixing the boards and preventing them from shaking.

[0046] Reference Figure 1 , Figure 2 and Figure 8The positioning component 7 includes a support frame 701. The top of the support frame 701 is fixedly connected to the bottom of the base 1, serving as the main frame of the positioning component 7 and connecting and supporting other components. The bottom of the support frame 701 is fixedly connected to four moving wheels 702. The outer walls of the support frame 701 are fixedly connected to the left and right sides of the outer wall, providing installation positions for the threaded rods 704. The inner walls of the multiple fixed blocks 703 are threaded with threaded rods 704. By engaging with the threads of the fixed blocks 703, the extension length of the rods can be adjusted. The bottom ends of the multiple threaded rods 704 are rotatably connected to positioning seats 705, increasing the contact area with the ground. When the threaded rods 704 are adjusted to the correct position, the positioning seats 705 contact the ground and provide friction, thereby firmly fixing the position of the board shelf.

[0047] Specifically, the support frame 701 connects the base 1 to the lower component, and the moving wheels 702 are fixed around the bottom of the support frame 701 to facilitate the overall movement of the shelf. When it is necessary to fix the position of the shelf, rotate the threaded rod 704 connected to the inner wall of the fixing block 703. Due to the action of the thread, the threaded rod 704 moves up and down, and the positioning seat 705 connected to its bottom end moves closer to or away from the ground until the positioning seat 705 contacts the ground and abuts, thereby achieving shelf positioning.

[0048] Reference Figure 1 , Figure 2 and Figure 3 A soft pad 8 is fixedly connected to the left side of the outer wall of the clamping plate 306. When the clamping plate 306 presses the plate, it prevents the clamping plate 306 from directly contacting the plate and causing damage to the plate surface. Multiple anti-slip grooves 9 are opened on the upper and lower sides of the left side of the outer wall of the soft pad 8, which can increase the friction between the soft pad 8 and the plate, making the clamping plate 306 more stable in fixing the plate. A traction block 10 is fixedly connected to the left side of the outer wall of the support frame 701. It provides a component for connecting external traction equipment to the mobile shelf. A reserved hole 11 is opened in the middle of the traction block 10, which is convenient to connect to the external traction device to move the shelf. A turntable 12 is fixedly connected to the right end of the lead screw 307. With a large rotation radius, it is easy for the operator to apply force to rotate the lead screw 307. A handle 13 is rotatably connected to the top right side of the outer wall of the turntable 12, which further facilitates the operator to hold and rotate the turntable 12.

[0049] Specifically, the soft pad 8 on the left side of the outer wall of the clamping plate 306 can cushion and prevent scratches when in contact with the board. The anti-slip groove 9 on it increases the friction with the board and better fixes the board. The traction block 10 on the left side of the outer wall of the support frame 701, through the reserved hole 11 in the middle, makes it convenient to connect external traction equipment with ropes and other tools to move the shelf. By turning the handle 13 on the turntable 12 at the right end of the screw 307, the turntable 12 and the screw 307 are rotated, so that the clamping plate 306 can be moved.

[0050] Working principle: In use, first place the boards on the base 1 and stack them. After the boards are placed, start the waterproofing process. First, remove the connecting rod 204 from the corresponding retaining ring 210. At this time, the waterproof cloth 203 is in an unfoldable state. Next, spread the waterproof cloth 203 along the direction of the mounting groove 202 to cover the board. Then, pull the corresponding pull ring 2094 outward. The pull ring 2094 drives the insertion rod 2091 to move. The limiting ring 2092 on the insertion rod 2091 moves accordingly, thereby compressing the spring 2093. At this time, the insertion rod 2091 slides out from the reserved hole 207 opened at the top of the outer wall of the rotating ring 206. Then, open the rotating ring 206 from the front and rear sides of the outer wall of the base 1. Rotate the connecting rod 204 out of the fixed groove 205 and then put it into the corresponding fixed groove 205. After completing the above steps, rotate the rotating ring 206 again to align the reserved hole 207 with the corresponding insertion rod 2091. Release the pull ring 2094. At this time, under the elastic force of the spring 2093, the spring 2093 pushes the limiting ring 2092 and the insertion rod 2091 to move towards the reserved hole 207. Finally, the insertion rod 2091 is inserted into the corresponding reserved hole 207, thereby fixing the rotating ring 206. The rotating ring 206 restricts the connecting rod 204 and prevents the connecting rod 204 from coming out of the fixed groove 205. In this way, together with the waterproof plate 201 on the top left and right sides of the base 1, the waterproof function of the plate is realized.

[0051] Before placing the boards, the position of the baffle 301 is first adjusted. Since an adjustment groove 302 is provided on the top left side of the base 1, the bottom of the baffle 301 can slide freely within the inner wall of the adjustment groove 302. Based on the size of the boards and actual stacking requirements, the baffle 301 is slid to a suitable distance within the adjustment groove 302. At this time, the multiple threaded holes 303 on the top left side of the base 1 come into play. By passing bolts 304 through the bottom left side of the baffle 301 and threading them into the corresponding threaded holes 303, the baffle 301 is firmly fixed in this position. The baffle 301 has two mutually perpendicular... The straight edges allow the boards to be stacked in a relatively orderly manner when they are first stacked. After the boards are stacked, they need to be further secured. At this time, the lead screw 307 is rotated. Since the inner wall of the guide groove 305 is rotatably connected to the lead screw 307, and the bottom of the clamping plate 306 is threadedly connected to the lead screw 307, the rotation of the lead screw 307 will cause the clamping plate 306 to slide in the guide groove 305 in the left and right direction under the action of the thread transmission principle. As the clamping plate 306 gradually moves towards the board, it will eventually squeeze the board, thus playing a stable fixing role for the board.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
