Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, and in particular to a lightweight steel grating with high strength and load-bearing capacity. Background Technology

[0002] Steel grating is an engineering material made of flat steel and crossbars welded or press-locked. It has the characteristics of high strength, anti-slip, ventilation and light transmission. It is widely used in industrial platforms, passageways, stairs, building decoration, traffic bridge decks and marine engineering fields. It is an indispensable building material in modern construction. In order to improve the strength of steel grating and reduce its weight, a high-strength load-bearing lightweight steel grating is needed.

[0003] A search revealed Chinese patent publication number CN214882693U, which discloses a high-strength steel grating, comprising a frame and a steel grating panel. The steel grating panel has several through holes, and the frame is provided with an embedding groove for installing the steel grating panel. Support columns are symmetrically arranged within the frame, and a crossbeam that fits with the support columns is provided on the top surface of the steel grating panel. The crossbeam includes an mounting part and a connecting part, with the connecting parts symmetrically arranged on both sides of the mounting part. A movable plate connected to the bottom surface of the mounting part via a spring is provided within the crossbeam, and reinforcing ribs are provided between the connecting part and the installed steel grating panel. This utility model utilizes support... The combination of support columns, crossbeams, and reinforcing ribs improves the overall load-bearing capacity of the steel grating, thereby increasing its stability and robustness. The springs and movable plates provide shock absorption, reducing the impact on the steel grating and thus increasing its service life. However, in actual use, this device enhances its structural strength by installing reinforcing ribs and crossbeams. While this reinforcement method improves the overall strength of the device, it also increases its weight. Furthermore, bending or folding can still occur after long-term use, thus reducing the reliability of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lightweight steel grating with high strength and load-bearing capacity, aiming to improve the problem that the existing steel grating will increase in weight and have general bending resistance after structural reinforcement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength load-bearing lightweight steel grating, comprising a frame, with grooves on both the left and right sides of the frame's interior, a rope wheel rotatably connected to the inner side of the groove, a steel cable disposed on the outer side of the rope wheel, spring rods fixedly connected to all four sides of the frame's interior, a steel plate fixedly connected to the top of the spring rods, a pre-drilled hole on the inner side of the steel plate, the outer side of the steel cable passing through the pre-drilled hole, a U-shaped block rotatably connected to the outer side of the rope wheel, a support fixedly connected to the bottom of the steel plate, the outer left and right sides of the support slidably connected to the U-shaped block, and a positioning mechanism disposed inside the frame for inserting and fixing the device.

[0006] The above technical solution involves a spring rod supporting the steel plate. When the steel plate bears weight, it compresses the spring and presses down on the steel cable. This action drives the support to move up and down, while the support drives the U-shaped block to move synchronously. The sliding action between the U-shaped block and the support drives the rope wheel to rotate, thereby tightening the steel cable. After the steel cable is tightened, the resulting prestress acts in the opposite direction on the steel plate. Its force is adjusted in real time according to the load on the steel plate to ensure that the steel plate does not deform and maintains the structural strength.

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

[0008] The positioning mechanism includes rotating wheels and belts. Multiple rotating wheels are rotatably connected to the inner top perimeter of the frame. All rotating wheels are connected via belt drive. A second bevel gear is fixedly connected to the bottom of each rotating wheel. A first bevel gear is rotatably connected to the inner perimeter of the frame. The first bevel gear meshes with the second bevel gear. A threaded post is fixedly connected to the outer side of the first bevel gear. A threaded block is threadedly connected to the outer side of the threaded post. A plug-in block is fixedly connected to the outer side of the threaded block. The outer side of the plug-in block penetrates the frame.

[0009] Through the above technical solution: the belt drive drives the rotating wheel to rotate, which in turn drives the wheels on both sides to rotate synchronously. The rotating wheel then drives the second bevel gear to rotate, and the first bevel gear and the threaded column that mesh with it also rotate. The rotation of the threaded column drives the threaded block and the plug block to move left and right. When the plug block extends out of the frame, it can be used to install and fix the device, realizing a fast and convenient assembly process.

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

[0011] The top four sides of the frame are rotatably connected to knobs, and the bottom of the knobs passes through the frame and is fixedly connected to the rotating wheel.

[0012] The above technical solution allows for easy manual operation of the rotating wheel by turning the knob.

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

[0014] Multiple indicator slots are provided around the outer perimeter of the frame, and an indicator block is fixedly connected to the top of the threaded block, with the top of the indicator block penetrating through the frame.

[0015] The above technical solution allows us to determine the current position of the threaded block by observing the indicator groove indicated by the indicator block.

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

[0017] The top of the steel plate has an installation groove, and a protective pad is fixedly connected to the inner side of the installation groove.

[0018] The above technical solution can extend the service life of the steel plate by installing a protective pad inside the groove.

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

[0020] The support is fixedly connected to brackets on all four sides of its exterior, and the top of the brackets is fixedly connected to the steel plate.

[0021] The above technical solution improves the connection stability between the steel plate and the support by using a bracket.

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

[0023] Positioning blocks are fixedly connected to the front and rear sides of the top of the frame, and positioning holes are provided on the outer side of the positioning blocks.

[0024] The above technical solution allows for easy installation and fixation of the device by inserting screws into the positioning holes.

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

[0026] The frame has grooves on all four sides of its inner side, and the outer side of the steel plate is slidably connected to the grooves.

[0027] The above technical solution improves the stability of the steel plate when it moves up and down by using a chute.

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

[0029] 1. In this utility model, a steel plate is supported by a spring rod. When the steel plate bears the load, it squeezes the spring and presses down the steel cable, pushing the support to move up and down. The movement of the support pulls the U-shaped block to move synchronously. The sliding of the U-shaped block and the support drives the rope wheel to rotate and tighten the steel cable. After the steel cable is tightened, the prestress applies pressure to the steel plate in the opposite direction. The force changes in real time with the load, keeping the steel plate from deforming and ensuring the structural strength, thereby improving the reliability of the device.

[0030] 2. In this utility model, when the rotating wheel is driven by the belt drive, the two wheels on both sides rotate synchronously. The rotating wheel drives the second bevel gear to rotate, which in turn drives the meshing first bevel gear and the threaded column to rotate. The rotation of the threaded column drives the threaded block and the plug block to move left and right. After the plug block extends out of the frame, it can be used to install and fix the device to achieve convenient assembly, thereby improving the convenience of the device.

[0038] 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model provides: a high-strength load-bearing lightweight steel grating, including a frame 1, with grooves 9 on both the left and right sides of the interior of the frame 1, a rope wheel 3 rotatably connected to the inner side of the groove 9, a steel cable 4 provided on the outer side of the rope wheel 3, spring rods 10 fixedly connected to the four sides of the interior of the frame 1, a steel plate 5 fixedly connected to the top of the spring rods 10, a reserved hole 6 opened on the inner side of the steel plate 5, the outer side of the steel cable 4 passing through the reserved hole 6, a U-shaped block 8 rotatably connected to the outer side of the rope wheel 3, a support 7 fixedly connected to the bottom of the steel plate 5, and the outer left and right sides of the support 7 slidably connected to the U-shaped block 8, and a positioning mechanism 2 provided inside the frame 1, which is used to insert and fix the device;

[0040] Specifically, the spring rod 10 supports the steel plate 5. When the steel plate is under load, it compresses the spring and presses down the steel cable 4 that passes through the reserved hole 6. As the steel plate 5 moves, it pushes the support 7 to move up and down. The support 7 drives the U-shaped block 8 to move synchronously. When the U-shaped block 8 slides with the support 7, it drives the rope wheel 3 to rotate and tighten the steel cable 4. After the steel cable 4 is tightened, it can apply pressure to the steel plate 5 in the opposite direction with prestress. The force changes in real time with the load, keeping the steel plate from deforming and ensuring the structural strength is stable.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The positioning mechanism 2 includes a rotating wheel 201 and a belt 202. Multiple rotating wheels 201 are rotatably connected to the inner top periphery of the frame 1. Multiple rotating wheels 201 are all connected by belt 202. A bevel gear 204 is fixedly connected to the bottom of the rotating wheel 201. A bevel gear 203 is rotatably connected to the inner periphery of the frame 1. The bevel gear 203 meshes with the bevel gear 204. A threaded post 205 is fixedly connected to the outer side of the bevel gear 203. A threaded block 206 is threadedly connected to the outer side of the threaded post 205. A plug-in block 207 is fixedly connected to the outer side of the threaded block 206. The outer side of the plug-in block 207 penetrates the frame 1.

[0042] Specifically, when the belt 202 drives the rotating wheel 201 to rotate, the two rotating wheels on both sides rotate synchronously. The rotating wheel 201 drives the bevel gear 204 to rotate, which in turn drives the bevel gear 203 and the threaded column 205 that mesh with it to rotate simultaneously. The rotation of the threaded column 205 causes the threaded block 206 and the plug block 207 to move left and right. After the plug block 207 extends out of the frame 1, it can be used for the installation and fixation of the device.

[0043] Reference Figure 1 , Figure 4 and Figure 5The top four sides of the frame 1 are rotatably connected to knobs 11, the bottom of the knobs 11 passes through the frame 1 and is fixedly connected to the rotating wheel 201; the outer four sides of the frame 1 are provided with multiple indicator grooves 14, the top of the threaded block 206 is fixedly connected to an indicator block 15, and the top of the indicator block 15 passes through the frame 1; the top of the steel plate 5 is provided with an installation groove 16, and the inner side of the installation groove 16 is fixedly connected to a protective pad 17.

[0044] Specifically, by rotating the knob 11, the rotating wheel 201 can be rotated synchronously. As the threaded block 206 moves, the indicator block 15 can be moved synchronously. The indicator slot 14 indicated by the indicator block 15 can be used to determine the current moving position of the threaded block 206 and the plug block 207. The pad 17 in the mounting slot 16 can improve the wear resistance of the steel plate 5 and extend its service life.

[0045] Reference Figure 3 , Figure 4 and Figure 5 Supports 18 are fixedly connected to the outer perimeter of the support 7, and the top of the support 18 is fixedly connected to the steel plate 5; positioning blocks 12 are fixedly connected to the front and rear sides of the top of the frame 1, and positioning holes 13 are opened on the outer side of the positioning blocks 12; sliding grooves 19 are opened on the inner perimeter of the frame 1, and the outer side of the steel plate 5 is slidably connected to the sliding grooves 19.

[0046] Specifically, the support of bracket 18 can enhance the support and structural strength of support 7 and steel plate 5. By installing threaded parts in positioning holes 13 in positioning block 12, it is easy to install and fix the device. By sliding the slide groove 19 with steel plate 5, the stability of steel plate 5 when moving up and down can be improved.

[0047] Working principle: Before using the device, the steel plate 5 is first supported by the spring rod 10. When the steel plate 5 is under load, it will squeeze the spring 5 and press down the steel cable 4 passing through the reserved hole 6. As the steel plate 5 moves, it will also push the support 7 to move up and down. As the support 7 moves, it will pull the U-shaped block 8 to move at the same time. With the movement of the U-shaped block 8 and its sliding with the support 7, the rope wheel 3 will rotate to tighten the steel cable 4. When the steel cable 4 is taut, it will apply pressure to the steel plate 5 in the opposite direction through prestress. This force will change in real time according to the load on the steel plate 5, so as to keep the steel plate 5 from deforming and maintain the structural strength.

[0048] Furthermore, through the transmission of the belt 202, when the rotating wheel 201 rotates, it can synchronously drive the rotating wheels 201 on both sides to rotate synchronously. At this time, as the rotating wheel 201 rotates, it will drive the bevel gear 204 to rotate, and drive the bevel gear 203 meshing with it and the threaded post 205 on it to rotate simultaneously. As the threaded post 205 rotates, it will drive the threaded block 206 and the plug block 207 on it to move left and right. When the plug block 207 moves out of the frame 1, the device can be installed and fixed through the extended plug block 207.

[0049] 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.
