Technical Field

[0001] This utility model relates to the field of steel grating technology, specifically a reinforced anti-slip steel grating. Background Technology

[0002] Steel grating, also known as steel grid, is a steel product made by arranging flat steel bars at certain intervals and crossbars and welding them together to form square grids in the middle. It is mainly used as drainage ditch covers, steel structure platform panels, and steel stair treads. When used as a steel structure platform panel, it needs to be constructed by splicing and installing multiple steel gratings.

[0003] However, current steel gratings are not effective at preventing slippage, and workers may encounter danger by slipping on them. Therefore, they do not meet the current needs, and we have proposed a reinforced anti-slip steel grating. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforced anti-slip steel grating to solve the problems mentioned in the background art, such as the current steel grating not being able to effectively prevent slippage, and the danger that workers may face when slipping on the steel grating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced anti-slip steel grating, comprising a steel grating body, the steel grating body comprising a frame, longitudinal steel strips and transverse steel strips, the longitudinal steel strips and transverse steel strips being fixedly connected to the frame to form the steel grating body, slots being provided at the four corners of the upper surface of the frame, and insert plates being movably installed on the inner side of each slot through a plug-in mechanism, the upper surfaces of the four insert plates being provided with an anti-slip mechanism, the anti-slip mechanism comprising a U-shaped anti-slip pad, a transverse anti-slip pad and a longitudinal anti-slip pad, and the transverse anti-slip pad, the longitudinal anti-slip pad and the U-shaped anti-slip pad being fixedly connected to form the anti-slip mechanism.

[0006] Preferably, the insertion mechanism includes a pull rod, which is installed on the front and rear sides of the outer surface of the steel grating body through a through hole. A second spring is sleeved on the outer surface of the pull rod, and a square groove is provided on the inner side of the through hole.

[0007] Preferably, a locking block is fixedly installed on the opposite side of the outer surface of each pair of pull rods, the size of the locking block is smaller than the size of the square groove, and a locking groove is provided on the opposite side of the outer surface of each pair of insert plates.

[0008] Preferably, the card block can be inserted into the inner side of the card slot, the upper end surface of the slot is provided with a groove, and the bottom surface of the groove is equipped with a first spring.

[0009] Preferably, a first inclined surface is provided on one side of the lower end face of the insert plate, and a second inclined surface is provided on one side of the upper end face of the card block.

[0010] Preferably, the upper surfaces of the U-shaped anti-slip mat, the transverse anti-slip mat, and the longitudinal anti-slip mat are uniformly provided with a plurality of anti-slip protrusions, and the connection between the transverse steel strip and the longitudinal steel strip is welded with a reinforcing member. The width of the transverse anti-slip mat is greater than the width of the transverse steel strip, and the width of the longitudinal anti-slip mat is greater than the width of the longitudinal steel strip.

[0011] Preferably, a plurality of first positioning posts are evenly installed on the lower end face of the transverse anti-slip pad, and a plurality of first positioning holes are provided on the upper end face of the transverse steel strip, wherein the first positioning posts can be inserted into the inner side of the first positioning holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates an anti-slip mechanism that can be installed above the main body of the steel grating. The width of the transverse anti-slip pad is greater than the width of the transverse steel strip, and the width of the longitudinal anti-slip pad is greater than the width of the longitudinal steel strip, increasing the contact area and further improving anti-slip performance. Furthermore, the inclusion of a plug-in mechanism allows for the disassembly and replacement of the anti-slip mechanism. Simultaneously pulling all four levers outwards moves the locking blocks, disengaging them from the inner side of the slots and releasing the limiting effect on the insert plate. The insert plate can then be positioned under the action of the first spring. When pushed upwards, the anti-slip mechanism can be removed from the main body of the steel grating and replaced. After the new anti-slip mechanism is replaced, when the first inclined surface contacts the second inclined surface, the insert plate will push the locking block towards the inside of the square groove. The locking block will retract into the inside of the square groove until the insert plate is fully inserted into the inside of the slot. Then, under the action of the second spring, the locking block will be inserted into the inside of the slot, limiting the insert plate. The anti-slip mechanism is now installed. This utility model has good anti-slip performance and allows for the replacement of the anti-slip mechanism, ensuring the anti-slip performance of the main body of the steel grating during subsequent use and improving safety performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides an embodiment of a reinforced anti-slip steel grating, comprising a steel grating body 1. The steel grating body 1 includes a frame 101, longitudinal steel strips 102, and transverse steel strips 103. The longitudinal steel strips 102 and transverse steel strips 103 are fixedly connected to the frame 101 to form the steel grating body 1. Slots 4 are provided at the four corners of the upper surface of the frame 101. Insert plates 5 are movably installed on the inner side of each slot 4 through a plug-in mechanism 3. Anti-slip mechanisms 2 are provided on the upper surfaces of the four insert plates 5. The anti-slip mechanism 2 includes a U-shaped anti-slip pad 201, a transverse anti-slip pad 202, and a longitudinal anti-slip pad 203. The transverse anti-slip pad 202 and the longitudinal anti-slip pad 203 are fixedly connected to the U-shaped anti-slip pad 201 to form the anti-slip mechanism 2.

[0021] The insertion mechanism 3 includes a pull rod 307, which is installed on the front and rear sides of the outer surface of the steel grating body 1 through a through hole 308. A second spring 306 is sleeved on the outer surface of the pull rod 307, and a square groove 305 is provided on the inner side of the through hole 308.

[0022] A locking block 304 is fixedly installed on the opposite side of the outer surface of each pair of pull rods 307. The size of the locking block 304 is smaller than the size of the square groove 305. A slot 301 is provided on the opposite side of the outer surface of each pair of insert plates 5. The locking block 304 can be retracted into the inside of the square groove 305.

[0023] The locking block 304 can be inserted into the inner side of the slot 301. The upper end face of the slot 4 is provided with a groove 302. The bottom surface of the groove 302 is equipped with a first spring 303. The locking block 304 can limit the position of the insert plate 5.

[0024] A first inclined surface is provided on one side of the lower end face of the insert plate 5, and a second inclined surface is provided on one side of the upper end face of the card block 304. When the first inclined surface and the second inclined surface are in contact, the insert plate 5 will push the card block 304 towards the inside of the square groove 305.

[0025] The upper surfaces of the U-shaped anti-slip mat 201, the transverse anti-slip mat 202, and the longitudinal anti-slip mat 203 are uniformly provided with several anti-slip protrusions to improve the anti-slip performance of the anti-slip mechanism 2. Reinforcing members 6 are welded at the connection between the transverse steel strip 103 and the longitudinal steel strip 102 to improve the stability of the connection between the transverse steel strip 103 and the longitudinal steel strip 102. The width of the transverse anti-slip mat 202 is greater than the width of the transverse steel strip 103, and the width of the longitudinal anti-slip mat 203 is greater than the width of the longitudinal steel strip 102, increasing the contact area and further improving the anti-slip performance.

[0026] Multiple first positioning posts are evenly installed on the lower end face of the transverse anti-slip pad 202, and multiple first positioning holes are provided on the upper end face of the transverse steel strip 103. The first positioning posts can be inserted into the inner side of the first positioning holes. Multiple second positioning posts are evenly installed on the lower end face of the longitudinal anti-slip pad 203, and multiple second positioning holes are provided on the upper end face of the longitudinal steel strip 102. The second positioning posts can be inserted into the inner side of the second positioning holes, thereby improving the stability of the transverse anti-slip pad 202 and the longitudinal anti-slip pad 203 installed on the transverse steel strip 103 and the longitudinal steel strip 102.

[0027] When in use, this reinforced anti-slip steel grating features an anti-slip mechanism 2, which can be installed above the main body 1 of the steel grating. The width of the transverse anti-slip pad 202 is greater than the width of the transverse steel strip 103, and the width of the longitudinal anti-slip pad 203 is greater than the width of the longitudinal steel strip 102, increasing the contact area and further improving anti-slip performance. Furthermore, the anti-slip mechanism 2 can be disassembled and replaced via a plug-in mechanism 3. Simultaneously, all four pull rods 307 can be pulled outwards, causing the locking block 304 to move. The locking block 304 moves away from the inner side of the locking groove 301, releasing the restriction on the insert plate 5. The insert plate 5 can then be released from the first spring 30. Under the action of 3, it is pushed upward, which can remove the anti-slip mechanism 2 from the steel grating body 1 and replace it. After the new anti-slip mechanism 2 is replaced, when the first inclined surface contacts the second inclined surface, the insert plate 5 will push the locking block 304 towards the inside of the square groove 305. The locking block 304 retracts into the inside of the square groove 305 until the insert plate 5 is completely inserted into the inside of the slot 4. Under the action of the second spring 306, the locking block 304 is inserted into the inside of the slot 301 to limit the insertion plate 5. The anti-slip mechanism 2 is installed. This utility model has good anti-slip performance and the anti-slip mechanism 2 can be replaced to ensure the anti-slip performance of the steel grating body 1 in subsequent use and improve safety performance.
