Description

Technical Field

[0001] This invention relates to the field of steel-plastic grating technology, specifically to a snap-fit ​​type hydraulic pressing equipment and pressing process for steel-plastic grating. Background Technology

[0002] Steel-plastic geogrid is a geosynthetic material composed of high-strength steel wire and plastics such as polyethylene (PE) or polypropylene (PP). It combines the high strength of steel with the corrosion resistance of plastic and is mainly used for reinforcement and strengthening in geotechnical engineering to improve the stability of foundations or structures. It uses high-strength galvanized steel wire as the load-bearing skeleton, and the steel wire is wrapped in a plastic layer through a special process to form a steel-plastic composite strip with a certain width. Then, the composite strips are arranged in a crisscross pattern and fixed at the nodes by welding, bonding or snap-fit ​​connection to form a grid structure.

[0003] When pressing existing snap-fit ​​steel-plastic gratings, the snaps are usually pressed in manually by hammering or using simple tools. Because it is difficult to uniform the force applied manually, problems such as insufficient snap-fit ​​depth and uneven force are very likely to occur, which directly leads to loosening of the node connection and creates safety hazards for the engineering structure. In addition, the manual pressing method is time-consuming and labor-intensive, with high operating costs per node, and requires a large number of workers, making it difficult to meet the needs of large-scale mass production.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Example 1: An embodiment of the present invention provides a snap-fit ​​type hydraulic pressing device for steel-plastic grating, such as... Figures 1-8 As shown, the system includes a base plate 1, a conveyor 15 on the base plate 1, a grid strip arranged in a mesh pattern on the conveyor 15, and several lower fasteners 17 installed on the conveyor 15. The intersections of the grid strips are located on the lower fasteners 17, and upper fasteners 21 are installed at the intersections of the grid strips. A constant hydraulic assembly is provided on the base plate 1, which includes a lower pressure plate 11. Several pressing components are provided on the lower pressure plate 11, and the pressing components include pressing blocks 8, which are used to press the upper fasteners 21 and the lower fasteners 17 together.

[0033] In the illustrations of this application, only two sets of clamping components are shown as an example to clearly demonstrate the core structure and working principle of the equipment. However, this does not constitute a limitation on the number of clamping components. Those skilled in the art can flexibly increase the number of clamping components according to actual production needs to adapt to the pressing operation of steel-plastic gratings of different specifications, thereby improving the versatility and production efficiency of the equipment.

[0034] The working principle and beneficial effects of the above technical solution are as follows: Several lower fasteners 17 are evenly installed on the conveyor 15 to position the intersection of the grid strips. Then, the intersection of the grid strips is installed on the lower fasteners 17. The upper fasteners 21 are placed above the intersection of the grid strips and initially cooperate with the lower fasteners 17 to clamp the grid strips, thus achieving pre-assembly. The constant hydraulic component drives the pressing component to operate through the lower pressure plate 11. The pressing block 8 directly acts on the upper fasteners 21, precisely pressing them against the lower fasteners 17 to fix the intersection of the grid strips. At the same time, the conveyor 15 cooperates to complete the continuous conveying and pressing process connection.

[0035] By setting a constant hydraulic component, a stable and precisely controllable pressure can be provided to drive the clamping block 8 to apply a uniform and constant pressing force to the upper clamping part 21 and the lower clamping part 17, ensuring that the two are tightly engaged and have a consistent depth. This effectively solves the problems of insufficient clamping and force deviation caused by uneven manual force application, and keeps the connection strength of each node uniform. At the same time, the equipment, together with the conveyor 15, can realize continuous operation of grid strip conveying, clamping positioning and pressing, which greatly improves the pressing speed of a single node, significantly reduces manual labor, and is more practical.

[0036] Example 2: Based on Example 1 above, as follows Figure 1 , Figures 3-6 As shown, a workbench 2 is installed on the base plate 1, and a conveyor 15 is installed on the workbench 2. The conveyor 15 includes a conveyor plate 10. A frame 13 is symmetrically installed on the left and right sides of the conveyor plate 10. Several evenly distributed mounting grooves 16 are opened on the conveyor plate 10. A lower fastener 17 is provided in the mounting groove 16. A cross groove 18 is opened on the lower fastener 17. Several insertion holes 19 are also opened on the lower fastener 17.

[0037] Preferably, the upper fastener 21 includes an arc-shaped top block, and a plurality of insertion rods 20 are provided on the lower surface of the arc-shaped top block; two fixing grooves are provided on the left and right side walls of the upper fastener 21, and two fixing grooves are provided on the left and right side walls of the lower fastener 17.

[0038] Preferably, the clamping block 8 is further provided with an arc-shaped groove 44, an arc-shaped plate 43 is slidably arranged in the arc-shaped groove 44, a second spring 42 is fixedly arranged on the arc-shaped plate 43, and the other end of the second spring 42 is fixedly connected to the arc-shaped groove 44.

[0039] The working principle and beneficial effects of the above technical solution are as follows: the mounting groove 16 on the conveyor plate 10 provides a precise installation position for the lower fastener 17, ensuring that it is arranged neatly; the cross groove 18 of the lower fastener 17 matches the cross shape of the grid strip, which can further fix the position of the grid strip; the dual positioning design of the mounting groove 16 and the cross groove 18 makes the fit between the grid strip and the lower fastener 17 more precise and reduces the pressing deviation.

[0040] The arc-shaped top block of the upper buckle 21 is adapted to the pressing action of the pressing block 8. The insertion rod 20 on its lower surface can be inserted into the insertion hole 19 of the lower buckle 17. The arc plate 43 inside the pressing block 8 is in flexible contact with the arc-shaped top block of the upper buckle 21 under the action of the spring 42, which not only ensures the pressing force, but also buffers the pressure impact through the sliding in the arc groove 44. The structure is simple, easy to use, and highly practical.

[0041] Example 3: Based on Example 2 above, as follows Figures 1-5As shown, the constant hydraulic assembly includes two symmetrical lifting rods 5. A horizontal plate 6 is fixedly installed on the upper end of each lifting rod 5. A constant hydraulic cylinder 9 is installed on the horizontal plate 6. The lower output end of the constant hydraulic cylinder 9 slides through the horizontal plate 6. The lower output end of the constant hydraulic cylinder 9 is fixedly connected to the lower pressure plate 11.

[0042] Preferably, the clamping assembly includes a clamping block 8, which is fixedly disposed on the lower surface of the lower pressure plate 11. Output channels 7 are symmetrically disposed on the left and right sides of the clamping block 8. The output channels 7 slide through the lower pressure plate 11 and are fixedly connected to the horizontal plate 6. The output channels 7 are used to convey the horizontal buckle 22. The horizontal buckle 22 is provided with two insertion rods 23 and two insertion rods 24. The insertion rods 23 cooperate with the fixing groove 1, and the insertion rods 24 cooperate with the fixing groove 2.

[0043] Preferably, clamping rods 12 are symmetrically arranged on the left and right sides of the clamping block 8. The clamping rods 12 are fixedly arranged on the lower pressure plate 11. The lower end face of the clamping rods 12 is set as trapezoidal. The clamping rods 12 are located on the side of the output channels 7 that are far apart from each other. A fixing block 27 is fixedly arranged at the far end of the output channels 7. A sliding rod 28 is slidably arranged through the center of the fixing block 27. A trapezoidal block 25 is fixedly arranged at one end of the sliding rod 28. The trapezoidal block 25 cooperates with the clamping rod 12. A push plate 29 is fixedly arranged at the other end of the sliding rod 28. The push plate 29 is used to push the transverse buckle 22 to move. A spring 26 is also sleeved on the sliding rod 28. One end of the spring 26 is fixedly connected to the trapezoidal block 25, and the other end of the spring 26 is fixedly connected to the fixing block 27.

[0044] The output channel 7 is equipped with several horizontal latches 22 and a control component. The control component is used to control that only one horizontal latch 22 falls in each output channel 7 at a time.

[0045] The working principle and beneficial effects of the above technical solution are as follows: The constant hydraulic cylinder 9 drives the lower pressure plate 11 to descend, which in turn drives the clamping block 8 fixed on its lower surface to move down synchronously, thus longitudinally pressing the upper and lower fasteners at the intersection of the grid bars; at the same time, the clamping rod 12 on the lower pressure plate 11 moves down accordingly, and its trapezoidal lower end face presses the trapezoidal block 25 next to the output channel 7, causing the sliding rod 28 to slide in the fixed block 27. The push plate 29 then pushes the transverse fastener 22 in the output channel 7 to the pressing position. The insertion rod 23 and the insertion rod 24 of the transverse fastener 22 cooperate with the fixing grooves of the upper and lower fasteners respectively to achieve transverse reinforcement.

[0046] The control components within the output channel 7 ensure that only one horizontal latch 22 falls at a time, guaranteeing pushing accuracy. The addition of the horizontal latch 22 significantly enhances the robustness of the grille connection through dual fixation in both the horizontal and vertical directions. The linkage design between the clamping rod 12 and the trapezoidal block 25 allows the horizontal latch pushing and vertical pressing to proceed synchronously, requiring no additional power, simplifying the structure while improving pressing efficiency. After pressing is completed, the constant hydraulic cylinder 9 drives the lower pressure plate 11 to rise, the spring 26 resets, and drives the sliding rod 28 and the push plate 29 back to their initial positions, awaiting the next action.

[0047] Example 4: Based on Examples 1-3, such as Figure 1 and Figure 7 As shown, drive rods 31 are provided on the lower surfaces of both the left and right ends of the lower pressure plate 11, and racks are installed on the drive rods 31; a gear ring 3 and a rotating rod 4 are symmetrically rotated on the worktable 2, and the rotating rod 4 is coaxial with the gear ring 3. The other end of the rotating rod 4 is rotatably connected to a gear 14, which meshes with the rack. A ratchet 30 is fixedly provided on the rotating rod 4, and several pawls 32 are installed on the gear ring 3, which cooperate with the ratchet 30; a toothed plate is fixedly provided on the lower surface of the frame 13, and the gear ring 3 meshes with the toothed plate.

[0048] The working principle and beneficial effects of the above technical solution are as follows: When the lower pressure plate 11 descends for pressing, the drive rods 31 at both ends move down synchronously. The rack on the drive rod 31 meshes with the gear 14, driving the gear 14 and the coaxial rotating rod 4 to rotate. The ratchet 30 on the rotating rod 4 rotates together. At this time, the pawl 32 on the toothed ring 3 slips in the rotation direction of the ratchet 30, and the toothed ring 3 remains stationary, ensuring that the conveyor 15 does not move during the pressing process. When the pressing is completed and the lower pressure plate 11 rises to reset, the drive rod 31 drives the gear 14 to rotate in the opposite direction. The rotating rod 4 and the ratchet 30 rotate in the opposite direction. At this time, the pawl 32 engages with the ratchet 30, driving the toothed ring 3 to rotate synchronously. The toothed ring 3 meshes with the toothed plate on the lower surface of the frame 13, thereby driving the conveyor 15 to move forward a certain distance and align the next pressing station with the pressing assembly.

[0049] The intermittent conveying of the conveyor 15 is directly driven by the lifting action of the lower pressure plate 11, without the need for an additional power source, which simplifies the equipment structure and reduces energy consumption. Through the cooperation of the ratchet 30 and the pawl 32, the conveying is triggered only when the lower pressure plate 11 rises and resets, and remains stationary during pressing, which ensures the accuracy of the pressing position.

[0050] Example 5: Based on Example 4 above, as follows Figure 1 and Figure 8As shown, an air box 37 is fixedly installed on one of the output channels 7. An air plate 40 is slidably installed inside the air box 37. A pressing rod 35 is fixedly installed on the upper end of the air plate 40. The pressing rod 35 extends upward out of the air box 37. A pressing plate 34 is fixedly installed on the upper end of the pressing rod 35. An air outlet pipe 38 is connected through to the lower end of the air box 37. A moving block 33 is also fixedly installed on the pressing block 8. The moving block 33 is slidably connected to the output channel 7. An air jet pipe 41 is fixedly connected through to the other end of the air outlet pipe 38. The air jet pipe 41 is symmetrically installed on the pressing block 8. An air jet head 39 is also fixedly installed at the air outlet end of the air jet pipe 41.

[0051] Among them, a spring 36 is also sleeved on the pressing rod 35. One end of the spring 36 is fixedly connected to the air box 37, and the other end of the spring 36 is fixedly connected to the air plate 40.

[0052] The air box 37 is also equipped with an air inlet, and both the air inlet and the air outlet pipe 38 are equipped with one-way valves.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When the lower pressure plate 11 drives the pressing block 8 to descend, the moving block 33 on the pressing block 8 moves down synchronously and contacts the pressing plate 34, pushing the pressing rod 35 to move downward, so that the air plate 40 in the air box 37 compresses the internal gas. The gas is transported to the jet pipe 41 through the air outlet pipe 38, and finally sprayed out through the jet head 39 to the pressing position of the upper and lower fasteners to remove dust or debris from the surface. After pressing is completed, the lower pressure plate 11 rises, the moving block 33 disengages from the pressing plate 34, the air plate 40 is reset under the elastic force of the spring 36, and the air box 37 re-intakes air to prepare for the next jet.

[0054] Automatic air jet cleaning is achieved through the lifting and lowering action of the clamping block 8, eliminating the need for an additional power source. This simplifies the equipment structure and ensures that the upper and lower clips and grid strips are free of impurities before pressing, preventing loose pressing or clip damage caused by foreign objects and improving pressing quality. The reset function of spring 36 ensures the circulating air supply of air box 37, making the cleaning action and pressing process precisely synchronized. This does not affect pressing efficiency and can continuously maintain the cleanliness of the pressing area, further enhancing the stability and reliability of the equipment.

[0055] Example 6: This example provides a hydraulic pressing process for snap-fit ​​steel-plastic grating. The process uses a snap-fit ​​steel-plastic grating hydraulic pressing device as described above to press the snap-fit ​​steel-plastic grating, including the following steps:

[0056] S1: Install several lower fasteners 17 onto the conveyor 15, and then lay the mesh-like grid strips on the conveyor 15 so that each intersection of the grid strips is accurately installed onto the lower fasteners 17 to complete the initial fixing;

[0057] S2: At the intersection of a horizontal row of grid bars directly opposite the clamping component, place the upper fastener 21 to initially align it with the lower fastener 17; activate the constant hydraulic component, and the lower pressure plate 11 drives the clamping block 8 to move downward, applying stable pressure to the upper fastener 21 through the clamping block 8, thus tightly pressing the upper fastener 21 and the lower fastener 17 together and fixing the intersection of the grid bars;

[0058] S3: After the pressing operation of the current horizontal row is completed, the conveyor 15 starts and conveys the grid strip forward a preset distance so that the intersection position of the grid strip to be pressed in the next horizontal row is accurately aligned with the pressing component; after placing the buckle 21 at the intersection position of the grid strip, the pressing operation of step S2 is repeated.

[0059] The working principle and beneficial effects of the above technical solution are as follows: First, several lower fasteners 17 are installed on the conveyor 15. Then, grid strips arranged in a mesh pattern are laid on the conveyor 15, so that each intersection of the grid strips is accurately installed on the lower fastener 17, completing the initial fixation. Then, at the intersection of a horizontal row of grid strips directly opposite the pressing component, upper fasteners 21 are placed accordingly, so that they are initially aligned with the lower fasteners 17. The constant hydraulic component is started, and the lower pressure plate 11 drives the pressing block 8 to move down. The pressing block 8 applies stable pressure to the upper fasteners 21, pressing the upper fasteners 21 and the lower fasteners 17 tightly together, thus fixing the intersection of the grid strips. Finally, after the pressing operation of the current horizontal row is completed, the conveyor 15 is started and the grid strips are conveyed forward a preset distance, so that the intersection of the grid strips to be pressed in the next horizontal row is accurately aligned with the pressing component. After placing the upper fastener 21 at the intersection of the grid strips, the pressing operation of step S2 is repeated.

[0060] By setting a constant hydraulic component, a stable and precisely controllable pressure can be provided to drive the clamping block 8 to apply a uniform and constant pressing force to the upper clamping part 21 and the lower clamping part 17, ensuring that the two are tightly engaged and have a consistent depth. This effectively solves the problems of insufficient clamping and force deviation caused by uneven manual force application, and keeps the connection strength of each node uniform. At the same time, the equipment, together with the conveyor 15, can realize continuous operation of grid strip conveying, clamping positioning and pressing, which greatly improves the pressing speed of a single node, significantly reduces manual labor, and is more practical.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
