Description

Technical Field

[0001] The invention belongs to the field of canal bridges, and in particular relates to a bridge device used for water conservancy canals. Background Art

[0002] In canal irrigation, in order to facilitate people to travel between the two sides of the canal, simple bridges are usually built at intervals on the canal; however, in actual use, the bridges that have been built on the canal are inappropriately located, so farmers need to take a long detour to pass through the canal via the nearest bridge, or build simple bridge boards at their own expense to facilitate farmers to use them during the small hours of irrigating their fields; at the same time, the bridge boards built at their own expense are likely to be used by others, causing nearby crops to be trampled by people who use the bridges, resulting in losses. Moreover, in the process of building at their own expense, considering the durability of the bridges, heavy steel is generally used, which will result in the bridges built with steel as private property being inconvenient to move and disassemble over long distances and easily rusting under rain erosion.

[0003] Considering the corrosion resistance and rust prevention of the bridge and its easy disassembly and assembly, it is necessary to design an easy-to-disassemble bridge that is corrosion-resistant and rust-proof and prevents others from using it at will.

[0004] The present invention designs a bridge device used in water conservancy canals to solve the above problems. Summary of the invention

[0042] like Fig. 9 , 11 As shown, the two ends of the shaft D54 are respectively rotatably matched with the two circular grooves A7 in the opening 6 of the housing 5, and the inner walls of the two circular grooves A7 are provided with annular grooves A8; the two volute springs C59 are respectively located in the two annular grooves A8; one end of the volute spring C59 is connected to the inner wall of the corresponding annular groove A8, and the other end is connected to the shaft D54; Figure 8 , 10 As shown, the two ends of the shaft B21 are respectively rotatably matched with the two circular grooves C11 symmetrically distributed on the top and bottom surfaces of the housing 5; the inner walls of the two circular grooves C11 are each provided with an annular groove B12; the two volute springs A22 are respectively located in the two annular grooves B12; one end of the volute spring A22 is connected to the inner wall of the corresponding annular groove B12, and the other end is connected to the shaft B21; Fig.12 , 16 As shown, the two ends of the shaft C35 are respectively rotatably matched with the circular grooves D30 on the two branches of the U-shaped seat 29; the inner walls of the two circular grooves D30 are each provided with an annular groove C31; the two spiral springs B60 are respectively located in the two annular grooves C31; one end of the spiral spring B60 is connected to the inner wall of the corresponding annular groove C31, and the other end is connected to the shaft C35. The annular groove A8 provides a space for the spiral spring C59 to accommodate, reducing the space occupied by the spiral spring on the shaft D54, thereby effectively reducing the length of the shaft D54; the annular groove B12 provides a space for the spiral spring A22; the annular groove C31 provides a space for the spiral spring B60 to accommodate, reducing the space occupied by the spiral spring C59 on the shaft C35, making the fit between the shaft C35 and the U-shaped seat 29 more compact, and making the swing rod B32 located between the two branches of the U-shaped seat 29 have a larger width, thereby increasing the strength of the swing rod B32.

[0043] like Figure 6 , 7 As shown in FIG. 17 , a guide rod 43 is installed at one end of the slider 36, and the guide rod 43 slides in the slide groove A10 on the side of the housing 5; the coil spring B42 is nested on the guide rod 43; one end of the coil spring B42 is connected to the slider 36, and the other end is connected to the inner wall of the housing 5. The guide rod 43 provides support for the coil spring B42 to prevent the coil spring B42 from bending during the compression process and failing to reset the slider 36.

[0044] like Figure 8 , 12 As shown in FIG. 16 , two trapezoidal guide blocks A27 are symmetrically mounted on the upper and lower surfaces of the baffle B25. The two trapezoidal guide blocks A27 slide in two trapezoidal guide grooves A13 on the inner wall of the housing 5 respectively. The cooperation between the trapezoidal guide blocks A27 and the trapezoidal guide grooves A13 plays a positioning and guiding role in the sliding of the baffle B25 in the housing 5. Figure 8 , 12 As shown in FIG. 17 , two trapezoidal guide blocks B38 are symmetrically mounted on the upper and lower surfaces of the slider 36. The two trapezoidal guide blocks B38 slide in two trapezoidal guide grooves B14 on the inner wall of the housing 5 respectively. The cooperation between the trapezoidal guide blocks B38 and the trapezoidal guide grooves B14 plays a positioning and guiding role in the sliding of the slider 36 in the housing 5. Figure 8 , 13 As shown in FIG. 19 , a trapezoidal guide block C58 is installed on the slide 57, and the trapezoidal guide block C58 slides in the trapezoidal guide groove C15 on the inner wall of the housing 5. The cooperation between the trapezoidal guide block C58 and the trapezoidal guide groove C15 plays a positioning and guiding role in the sliding of the slide 57 in the housing 5. Fig. 20 As shown, two guide blocks 49 are symmetrically installed on the inner plate 47 of the telescopic plate 44. The two guide blocks 49 slide respectively in the two guide grooves 46 on the inner wall of the outer plate 45 of the telescopic plate 44. The cooperation between the guide blocks 49 and the guide grooves 46 plays a positioning and guiding role in the sliding of the inner plate 47 in the outer plate 45, and at the same time ensures that the coil spring D50 in the outer plate 45 is always in a compressed state, so as to facilitate the complete resetting of the inner plate 47 relative to the outer plate 45.

[0045] like Figure 5 , 6 As shown, the door panel 55 is provided with a handle 56 for convenient opening thereof; Figure 6 As shown, a support block 33 is installed on the side of the end of the swing rod B32, and a friction pad 34 is installed on the side of the support block 33; Figure 6 , 17 As shown, a pressing plate 40 is installed at one end of the slide rod 39 ; a coil spring C41 is nested on the slide rod 39 ; one end of the coil spring C41 is connected to the slider 36 , and the other end is connected to the pressing plate 40 .

[0046] In the present invention, the distance between the inner plate 47 of the telescopic plate 44 and the baffle A23 is slightly smaller than the sum of the thicknesses of the support block 33 and the friction pad 34, ensuring that when the support block 33 passes over the inner plate 47 driven by the rocker arm B32, the friction pad 34 is squeezed and deformed, and the support block 33 and the friction pad 34 are completely located between the inner plate 47 and the baffle A23, so that the inner plate 47 restricts the support block 33 from swinging back and resetting with the rocker arm B32, thereby ensuring effective friction between the friction pad 34 and the baffle A23, thereby limiting the movement of the baffle A23 under misoperation, thereby preventing the lock mechanism 4 of the present invention from being unlocked when it is misoperated.

[0047] The working process of the present invention is as follows: in the initial state, the two volute springs A22 are in a compressed energy storage state, the upper limit hook 20 of the swing rod A19 is located in a limit groove 18 on the rim of the limit wheel 17 to prevent the housing 5 from rotating around the axis A16, thereby limiting the support frame 2 from rotating and swinging synchronously with the housing 5 around the axis A16; the two volute springs B60 are in a compressed energy storage state, one end of the swing rod B32 that cooperates with the inner plate 47 of the telescopic plate 44 is in close contact with the baffle B25, and the trapezoidal guide block A2 on the baffle B25 7 is located at the limit of one end of the trapezoidal guide groove A13 away from the telescopic plate 44, and the spiral spring A28 is pre-stretched to store energy; the slide groove B24 on the baffle A23 is located between the two slide grooves C26 on the baffle B25 that are farthest from the telescopic plate 44; the support block 33 is located opposite to the inclined surface 48 on the inner plate 47 of the telescopic plate 44; the door panel 55 is in a closed state, and the distance between the inner plate 47 of the telescopic plate 44 and the support block 33 is at a maximum state; the two spiral springs C59 are in a compressed energy storage state.

[0048] When the present invention is needed, the exposed end of the axis A16 in the locking mechanism 4 of the present invention is fixedly installed on the bank of the canal 1, so that the length direction of the support frame 2 is parallel to the water flow direction in the canal 1, and the support frame 2 is placed flat on the bank of the canal 1. Pull the handle 56 on the door panel 55 to open the door panel 55. During the opening process of the door panel 55, the door panel 55 drives the axis D54 to rotate synchronously, and the two spiral springs C59 are further compressed to store energy; the axis D54 drives the gear 53A installed thereon to rotate synchronously, and the gear 53A drives the telescopic plate 44 to move synchronously as a whole toward the support block 33 through the rack 52A and the connecting rod 51. When the door panel 55 is fully opened around the axis D54, the inclined surface 48 at the end of the inner plate 47 of the telescopic plate 44 contacts the support block 33, and the inner plate 47 of the telescopic plate 44 contracts to a certain extent into the outer plate 45 under the action of the support block 33, and the spiral spring D50 is further compressed to store energy.

[0049] Then, the user pushes the slide bar 39 in the direction away from the slide seat 57, and the slide bar 39 drives the slider 36 to move synchronously, and the coil spring B42 is compressed to store energy; when the slide bar 39 drives the slider 36 to slide in the direction away from the slide seat 57 to the limit position, it is slightly pushed a small distance, so that the rod end of the slide bar 39 is completely opposite to the slide groove C26 on the baffle B25 that is farthest from the telescopic plate 44, and at this time, the pressing plate 40 is pressed in a direction perpendicular to the sliding direction of the slide bar 36, and the pressing plate 40 drives the rod end of the slide bar 39 to quickly pass through the slide groove C26 on the baffle B25 that is farthest from the telescopic plate 44, and the coil spring C41 is compressed to store energy; then Move the slide bar 39 back a small distance by hand, and the slide bar 39 drives the baffle B25 to move synchronously. The baffle B25 drives the support block 33 to further compress the inner plate 47 of the telescopic plate 44 through the U-shaped seat 29, the shaft C35 and the rocker bar B32. The coil spring D50 in the telescopic plate 44 is further compressed to store energy, and the coil spring A28 is further stretched to store energy, so that the rod end of the slide bar 39 is completely opposite to the slide groove B24 on the baffle A23; then continue to press the pressing plate 40 by hand, and the pressing plate 40 drives the slide bar 39 to continue to quickly pass through the slide groove B24 on the baffle A23, and the coil spring C41 is further compressed to store energy again.

[0050] Continue to press the pressing plate 40, the pressing plate 40 drives the slide rod 39 passing through the slide groove B24 to quickly act on the rocker arm A19, and the coil spring C41 is continuously compressed to store energy, so that the rocker arm A19 swings around the central axis of the shaft B21 in the direction away from the limiting wheel 17; the limiting hook 20 on the rocker arm A19 quickly disengages from the corresponding limiting groove 18 on the limiting wheel 17 and releases the rotation and swing of the shell 5 around the axis A16, and the lock mechanism 4 is now completely unlocked.

[0051] Then, the support frame 2 starts to be pushed to swing around the axis A16 in the direction across the water surface of the canal 1. The support frame 2 drives the outer shell of the locking mechanism 4 to rotate and swing around the axis A16 and relative to the axis A16. The shell 5 drives all the components installed therein to swing synchronously around the axis A16, and the limiting hook 20 of the rocker arm A19 moves around the axis A16 toward another limiting groove 18 on the limiting wheel 17. In the process of the locking mechanism 4 accepting and being driven by the support frame 2 to swing the shell 5 and all the components installed therein in the direction across the water surface of the canal 1, the forces acting on the pressing plate 40 and the door panel 55 are successively removed and the support frame 2 is continuously pushed to swing in the direction across the water surface of the canal 1.

[0052] When the force on the pressing plate 40 is removed, under the reset action of the coil spring C41, the slide bar 39 instantly disengages from the slide groove B24 on the baffle A23 and the slide groove C26 on the baffle B25 and completely resets relative to the slider 36. At the same time, under the reset action of the coil spring A28, the baffle B25 drives the U-shaped seat 29, the swing rod B32, the support block 33 and the friction pad 34 to completely reset relative to the housing 5, the support block 33 is still in close contact with the inclined surface 48 of the plate end of the inner plate 47 of the telescopic plate 44, and the inner plate 47 is still partially compressed by the support block 33 in the outer plate 45; under the reset action of the coil spring B42, the slider 36 is completely reset relative to the housing 5.

[0053] When the force on the door panel 55 is removed, under the reset action of the two spiral springs C59, the shaft D54 drives the door panel 55 to close quickly, and at the same time, the shaft D54 drives the gear 53A to rotate synchronously. The gear 53A drives the telescopic plate 44 to reset quickly through a series of transmissions. The inclined surface 48 at the end of the inner plate 47 of the telescopic plate 44 quickly disengages from the support block 33 and is completely reset relative to the outer plate 45 under the reset action of the spiral spring D50.

[0054] During the swinging of the support frame 2 in the direction of crossing the water surface of the water channel 1, since the slide bar 39 acting on the swing rod A19 has been separated from the swing rod A19, the upper limit hook 20 on the swing rod A19 is closely attached to the rim surface of the limiting wheel 17 under the reset action of the two spiral springs A22 and moves to the next limiting groove 18. When the support frame 2 is completely across the water surface of the water channel 1, the support frame 2 just swings 90 degrees around the axis A16, and the limit hook 20 on the swing rod A19 just meets another limit groove 18; under the reset action of the two spiral springs A22, the axis B21 drives the limit hook 20 through the swing rod A19 to instantly embed into the corresponding limit groove 18 and resume the restriction on the rotation of the housing 5 relative to the axis A16; so that the support frame 2 crossing the water channel 1 will not swing during use, ensuring that the support frame 2 always crosses the water channel 1 during use, thereby ensuring the safety of the user during use.

[0055] When a person wants to reach the other side of the canal 1 through the present invention, he first lays the plank 3 on the support frame 2, and then steps on the plank 3 to reach the other side of the canal 1. The plank is a plurality of wooden boards connected in sequence by soft ropes, which can be rolled up when not in use, so as to facilitate transportation and storage.

[0056] When the support frame 2 and the deck 3 across the canal 1 are used up and the support frame 2 needs to be recovered, the deck 3 is recovered first and then the above-mentioned operation process of the locking mechanism 4 is repeated to unlock the locking mechanism 4, so that the limit hook 20 on the swing rod A19 is completely separated from the corresponding limit groove 18, and then the support frame 2 is swung back around the axis A16. When the support frame 2 completely swings back from the state of spanning the water surface of the canal 1 to the initial state, the support frame 2 just swings back 90 degrees around the axis A16, and the limit hook 20 on the swing rod A19 just meets the limit groove 18 matched with it in the initial state; under the reset action of the two spiral springs A22, the shaft B21 drives the limit hook 20 through the swing rod A19 to instantly embed into the corresponding limit groove 18 and restore the restriction on the rotation of the housing 5 relative to the axis A16; so that the support frame 2 in the initial state will not swing under the blind operation of others, ensuring that the present invention is only used by the owner, and avoiding the crops on both sides of the canal 1 being trampled by others using the present invention.

[0057] If someone else uses the present invention in the initial state when the owner is not present, when the other person opens the door panel 55, the door panel 55 drives the telescopic plate 44 to move to the support block 33 through a series of transmissions, and the inner plate 47 of the telescopic plate 44 contracts a certain distance into the outer plate 45 under the action of the support block 33, and the coil spring D50 is further compressed to store energy; then the other person will blindly press the pressing plate 40 or push the slide bar 39 to move; under the blind pressing and pushing, the pressing plate 40 drives the slide bar 39 to enter the baffle B25. When it is impossible to enter any of the slide grooves C26 on the baffle B25 and enter the slide groove C26 farthest from the telescopic plate 44, the coil spring C41 is compressed to store energy, the coil spring B42 is deformed to store energy, and the coil spring A28 is deformed to store energy; under the continued push of the slide rod 39 passing through any of the slide grooves C26 on the baffle B25, the slide rod 39 drives the swing rod B32 hinged to the side of the baffle B25 to swing rapidly toward the baffle A23 around the axis C35; the swing rod A19 drives the support block 33 to act on the inclined surface 48 on the inner plate 47 of the telescopic plate 44, so that the telescopic plate 44 is moved to the inner plate 47 of the telescopic plate 44. The inner plate 47 of the retractable plate 44 continues to retract into the outer plate 45, and the coil spring D50 is further compressed to store energy; when the support block 33 quickly passes over the end of the inclined surface 48 of the inner plate 47, the friction pad 34 has contacted with the baffle A23 and is pressurized and deformed; under the reset action of the coil spring D50, the inner plate 47 of the telescopic plate 44 is instantly reset relative to the outer plate 45 and restricts the swing back of the support block 33 with the swing rod B32, so that the friction pad 34 maintains continuous extrusion and friction cooperation with the baffle A23; at this time, when the slide rod 39 is manually pushed again to drive the baffle When B25 moves, due to the greater friction between the friction pad 34 and the baffle A23, the support block 33 prevents the slide bar 39 from continuing to drive the slide block 36 to move through the rocker arm B32, the U-shaped seat 29 and the baffle B25, thereby preventing other people other than the owner from terminating the operation of the present invention, and the lock mechanism 4 is not unlocked; the present invention can no longer continue the operation, and other people other than the owner will give up using the present invention, thereby preventing other people from arbitrarily using the present invention to pass through the canal 1 when the owner is not present, causing the crops on both sides of the canal 1 to be trampled.

[0058] When other people who are not the owner remove the force acting on the pressing plate 40, the slide bar 39 disengages from the slide groove C26 and resets relative to the slider 36 under the reset action of the coil spring C41, and the slider 36 resets under the reset action of the coil spring B42; due to the interaction between the friction pad 34 and the baffle A23, the baffle B25 will not be reset temporarily under the reset action of the coil spring A28; when other people who are not the owner remove the force acting on the door panel 55, under the reset action of the two volute springs C59, the door panel 55 drives the telescopic plate 44 to be completely reset through a series of transmissions and releases the restriction on the swing back of the support block 33 with the rocker arm B32; under the reset action of the two volute springs B60, the rocker arm B32 drives the support block 33 and the friction pad 34 to reset instantly relative to the baffle B25; under the reset action of the coil spring A28, the baffle B25 drives the rocker arm B32, the support block 33 and the friction pad 34 to be completely reset through a series of transmissions.

[0059] When the use cycle of the present invention is completely completed, the shaft A16 can be detached from the bank of the water channel 1 and the present invention can be disassembled from the bank of the water channel 1.

[0060] The shaft A in the present invention can be fixed at a fixed position of the canal during the entire life cycle, so that the bridge can be placed beside the canal for a long time, and the bridge is completely fixed beside the canal. Because the anti-corrosion structure is added, it still has a certain corrosion resistance.

[0061] In summary, the beneficial effects of the present invention are as follows: as a private property, the present invention can be built or dismantled from the canal 1 at any time as needed, so as to prevent the crops on both sides of the canal 1 from being trampled at will by people around using the present invention for shortcuts; at the same time, during the peak period when the present invention is frequently used, when the user uses it, the user unlocks the lock mechanism 4 to realize the swing of the present invention and builds the present invention above the water surface of the canal 1 to facilitate the user's activities between the two sides of the canal 1; when not in use, the user unlocks the lock mechanism 4 and then removes the present invention from the water surface of the canal 1 to prevent the surrounding crops from being trampled by others when the user is temporarily not by the canal 1. The lock mechanism 4 in the present invention is only known to its owner how to unlock it, and other people do not know its specific unlocking method, thereby avoiding the phenomenon that the crops on both sides of the canal 1 are trampled by others when the owner of the present invention is not on site. Compared with the traditional lap boards on the canal 1 that are spaced at a long distance, the present invention can pass through the canal 1 at any part of the canal 1. It is lightweight and easy to operate, and can effectively prevent others from using the present invention to pass through the canal 1 at will, causing their own crops to be trampled on by others at will. In addition, the floor boards 3 in the present invention can be disassembled and stored at any time to prevent the floor boards 3 from being wetted by rain when not in use, thereby reducing their service life.
