Description
Technical Field
[0001] This utility model relates to the field of drainage ditch cover technology, specifically to a reinforced concrete drainage ditch cover that can be quickly disassembled and installed. Background Technology
[0002] Road drainage ditches are ditches that collect water in low-lying areas near the roadbed. They need to drain water from the road surface. To ensure the safety of pedestrians and vehicles, a frame needs to be installed at the opening of the drainage ditch and a cover plate needs to be embedded in the frame to cover the opening of the drainage ditch and ensure the safety of passing vehicles and pedestrians. Currently, reinforced concrete drainage ditch covers are widely used in drainage ditches. They are made of high-strength concrete as the base material and have an internal steel reinforcement frame. They are used to cover drainage ditches and have high strength and good durability. However, in the existing technology, when installing the cover plate, it is placed in the trench and aligned with the ground level. It is usually fixed by filling the gaps with cement mortar or by welding it to the trench wall. Disassembly requires breaking the mortar and cutting the weld points, which is not only time-consuming but may also damage the cover plate or the trench wall, leading to increased secondary repair costs. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a reinforced concrete drainage ditch cover that can be quickly disassembled and assembled, which solves the technical problems of the prior art where the cover is cumbersome to disassemble and assemble, inconvenient to disassemble and assemble quickly, and time-consuming and labor-intensive.
[0004] According to one aspect, at least one embodiment of the present invention provides a quick-release reinforced concrete drainage ditch cover plate, applied to a ditch, comprising a cover plate body, two symmetrically formed slots on the ditch, and further comprising an installation platform, a locking plate, and a clamping groove. The installation platform is detachably mounted on the slots, and the locking plate is rotatably mounted on the outside of the cover plate body via a rotating mechanism. The installation platform has a slot that mates with the locking plate, and the installation platform has a clamping groove that mates with the locking plate. The clamping groove and the slot are connected for fixing the cover plate body to the two installation platforms in conjunction with the locking plate and the rotating mechanism.
[0005] Preferably, the rotating mechanism includes a connecting rod, a rotating frame, a rotating shaft, and a rotating plate. The connecting rod is rotatably disposed within the cover plate body, one end of the connecting rod is fixedly connected to one end of the locking plate, one end of the rotating frame is fixedly connected to one end of the connecting rod, the rotating shaft is rotatably disposed within the rotating frame, and one end of the rotating plate is fixedly connected to the rotating shaft.
[0006] Furthermore, in order to enable the locking plate to cooperate with the rotating mechanism and the locking groove to achieve longitudinal fixation of the locking plate, the locking plate can be L-shaped.
[0007] Furthermore, in order to enable the locking plate to abut against and slide against the inner wall of the locking groove when the rotating mechanism rotates, the other end of the locking plate is provided with an arc-shaped abutment part, and the locking groove is fan-shaped.
[0008] As a further aspect of this application, in order to enable the locking plate to abut against the cover plate body and move the cover plate body out of the groove when the rotating mechanism is pulled upward to move the locking plate upward, the bottom end of the cover plate body is provided with an abutment groove that cooperates with the locking plate.
[0009] As a further improvement in this application, in order to support the rotating frame and provide space for the rotating frame to rotate, the two ends of the rotating frame are arc-shaped, and the cover plate body is provided with a sliding groove that cooperates with the rotating frame.
[0010] Based on the aforementioned solution, in order to fix the rotating plate after the locking plate rotates into the locking groove, thereby fixing the locking plate, threaded holes are provided on the inner walls of both the rotating plate and the sliding groove, and locking bolts are threaded into both threaded holes.
[0011] Furthermore, in order to facilitate the lifting of the cover plate body out of the groove by rotating the rotating plate after the locking plate is removed from the locking groove, the rotating plate is provided with a through groove.
[0012] The beneficial effects of this utility model are as follows: In this invention, the mounting platform, locking plate, rotating mechanism, and clamping groove are used in conjunction. The mounting platform is fixed to the inner wall of the groove using expansion bolts. By passing a plate through two rotating plates and then lifting the plate upwards, the cover plate body can be moved to the groove. The cover plate body is placed on the two mounting platforms, the plate is removed, and the locking plate enters the slot. By rotating the two rotating plates, the locking plate enters the clamping groove, thus fixing the locking plate longitudinally. Then, by rotating (flipping) the rotating plates, the rotating plates are placed in the rotating frame, and the two threaded holes on the bottom wall of the groove correspond to the rotating plates. The rotating plates are fixed using locking bolts to prevent the rotating plates from continuing to rotate and causing the locking plates to rotate, which would loosen the cover plate body. This also facilitates the disassembly of the cover plate body. Attached Figure Description

[0022] like Figures 1-7 As shown, it illustrates a quick-assembly and disassembly reinforced concrete drainage ditch cover in one embodiment of the present invention, applied to a ditch 1, including a cover body 2, two symmetrical slots 3 on the ditch 1, and also including an installation platform 4, a locking plate 5 and a clamping groove 7. like Figure 3As shown, the mounting platform 4 is detachably mounted on the slot 3. It should be added that by pre-drilling holes in the inner sidewalls of the two slots 3, the mounting platform 4 is L-shaped. Through holes 18 are provided on the sidewalls of the mounting platform 4. By using expansion bolts 19 to pass through the through holes 18 and the holes drilled in the slots 3, the mounting platform 4 is fixed to the inner wall of the slot 3. like Figure 4 and Figure 6 As shown, the mounting platform 4 has a slot 6 that mates with the locking plate 5, and a clamping groove 7 that mates with the locking plate 5. In order to enable the locking plate 5 to abut against and slide against the inner wall of the clamping groove 7 when it rotates with the rotating mechanism, the other end of the locking plate 5 is provided with an arc-shaped abutment part 12. The clamping groove 7 is fan-shaped and the clamping groove 7 and the slot 6 are connected. It is used to fix the cover plate body 2 on the two mounting platforms 4 in conjunction with the locking plate 5 and the rotating mechanism. like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the locking plate 5 is rotatably movable on the outside of the cover plate body 2 via a rotating mechanism. To enable the locking plate 5 to be longitudinally fixed in conjunction with the rotating mechanism and the locking groove 7, it can be L-shaped. The rotating mechanism includes a connecting rod 8, a rotating frame 9, a rotating shaft 10, and a rotating plate 11. The connecting rod 8 is rotatably disposed within the cover plate body 2, with one end of the connecting rod 8 fixedly connected to one end of the locking plate 5. One end of the rotating frame 9 is fixedly connected to one end of the connecting rod 8. To support the rotating frame 9 and provide space for its rotation, both ends of the rotating frame 9 are arc-shaped. The cover plate body 2 has a sliding groove 14 that mates with the rotating frame 9. The rotating shaft 10 is rotatably disposed within the rotating frame 9, located at one end of the rotating frame 9 (not at the center). One end of the movable plate 11 is fixedly connected to the rotating shaft 10. In order to fix the movable plate 11 after the locking plate 5 rotates into the clamping groove 7, the inner walls of the movable plate 11 and the slide groove 14 are provided with threaded holes 15. Both threaded holes 15 are threaded with locking bolts 16. In order to make the locking plate 5 abut against the cover plate body 2 and move the cover plate body 2 out of the groove 1 when the rotating mechanism is pulled upward to move the locking plate 5 upward, the bottom end of the cover plate body 2 is provided with an abutment groove 13 that cooperates with the locking plate 5. In order to make it easy for the staff to use tools or hold the movable plate 11 to lift the cover plate body 2 out of the groove 1 after the locking plate 5 moves out of the clamping groove 7, the movable plate 11 is provided with a through groove 17. In the initial state, the bottom end of the rotating frame 9 abuts against the inner bottom wall of the slide groove 14. At this time, the locking plate 5 is located on the lower side of the cover plate body 2. With the locking plate 5 corresponding to the abutment groove 13, and by keeping the two rotating plates 11 in a vertical state, a plate can be passed through the two through grooves 17, or two workers can hold the two rotating plates 11 respectively (like handles), and then pull the plate upward to make the locking plate 5 "insert" into the abutment groove 13. Then move it to the groove 1 and place the cover plate body 2 on the two mounting platforms 4. After that, by releasing the plate, the rotating frame 9 abuts against the inner bottom wall of the slide groove 14. At the same time, the connecting rod 8 moves downward, and the locking plate 5 moves out of the abutment groove 13 and into the slot 6 in the mounting platform 4. The plate is removed, and by rotating the two rotating plates 11, the rotating plates 11 drive the rotating shaft 10 and the rotating frame 9 to rotate. The rotating frame 9 drives the connecting rod 8 to rotate, and the connecting rod 8 drives the locking plate 5 to rotate. After the locking plate 5 rotates, it enters the clamping groove 7, thus achieving the longitudinal fixation of the locking plate 5. It should be added that the cover plate body 2 is supported by multiple support seats before installation. The bottom end of the cover plate body 2 and the bottom end of the locking plate 5 are "detached" from the ground. It should also be added that by rotating the rotating plate 1190 degrees, the outer side wall of the locking plate 5 abuts against the other inner side wall of the locking groove 7. By rotating (flipping) the rotating plate 11, the rotating plate 11 is placed inside the rotating frame 9, and the two threaded holes 15 on the inner bottom wall of the rotating plate 11 and the slide groove 14 correspond to each other. The rotating plate 11 is fixed by using the locking bolt 16 to prevent the rotating plate 11 from continuing to rotate and causing the locking plate 5 to rotate, which would cause the cover plate body 2 to become loose. Working principle: During installation, the quick-assembly and disassembly reinforced concrete drainage ditch cover is pre-drilled in the inner walls of the two slots 3. The installation platform 4 is L-shaped and has through holes 18 on its side walls. Expansion bolts 19 are used to pass through the through holes 18 and the holes drilled in the slots 3 to fix the installation platform 4 to the inner wall of the slots 3. By passing a plate through the two rotating plates 11 and then pulling the plate upward, the locking plate 5 is "inserted" into the abutment groove 13. This moves the cover body 2 to the ditch 1 and places it on the two installation platforms 4. Then, by releasing the plate, the rotating frame 9 abuts against the inner bottom wall of the slide 14, and the connecting rod 8 moves downward to lock it in place. Plate 5 is moved out of the abutment groove 13 and into the slot 6 in the mounting platform 4. The plate is removed, and by rotating the two rotating plates 11, the rotating plates 11 drive the rotating shaft 10 and the rotating frame 9 to rotate. The rotating frame 9 drives the connecting rod 8 to rotate, and the connecting rod 8 drives the locking plate 5 to rotate. After the locking plate 5 rotates, it enters the clamping groove 7, thus achieving longitudinal fixation of the locking plate 5. Then, by rotating (flipping) the rotating plate 11, the rotating plate 11 is placed in the rotating frame 9, and the two threaded holes 15 on the bottom wall of the rotating plate 11 and the slide groove 14 correspond to each other. The rotating plate 11 is fixed by using the locking bolt 16 to prevent the rotating plate 11 from continuing to rotate and causing the locking plate 5 to rotate, which would cause the cover plate body 2 to become loose. This also makes it easier to disassemble the cover plate body 2.
