Description

Technical Field

[0001] This utility model relates to the field of gate and traffic bridge protection technology, and in particular to a gate and traffic bridge protection railing. Background Technology

[0002] A sluice gate traffic bridge is a bridge built on the sluice gate chamber, mainly used to connect traffic on both sides of the sluice gate. Guardrails are safety facilities installed on sluice gate traffic bridges, primarily to prevent vehicles or pedestrians from accidentally falling off the bridge. Guardrails effectively prevent out-of-control vehicles from running off the bridge surface and avoid vehicles and pedestrians falling into the water, thus protecting life and property. Therefore, a type of guardrail is used on sluice gate traffic bridges.

[0003] A search revealed a Chinese patent announcement number: CN211368370U, which discloses a protective railing for bridge construction, including a railing body. The two sides of the railing body are fixedly connected by iron cables, and the opposite side of the railing body is fixedly connected by mounting plates. Both mounting plates have sealing cavities inside. An airbag is fixedly connected to the rear side of the inner wall of the sealing cavity. The front and rear sides of the inner wall of the sealing cavity are fixedly connected by positioning rods, and springs are fixedly sleeved on the surfaces of both ends of the positioning rods.

[0004] In the aforementioned utility model, the guardrail for bridge construction, when a vehicle vehicle comes into contact with the roller in a traffic accident, the roller rolls under the action of external force. When the lateral impact force is too large, the roller is hit, causing the rotating rod fixedly connected to the roller to drive the movable box to slide in the sealed cavity inside the mounting plate. At this time, the slider compresses the spring to its maximum deformation point, the elasticity fails, the movable box hits the airbag, the airbag explodes, and the sealed cavity prevents the gas released in an instant from dissipating, thus causing a certain rebound, which can play a certain buffering role. However, in actual use, it does not integrate water level monitoring or early warning functions and cannot adapt to the trend of intelligent management of gate stations. Utility Model Content

[0005] To address the above shortcomings, this utility model provides a gate station traffic bridge guardrail, which aims to improve the problem that it does not integrate water level monitoring or early warning functions in actual use and cannot adapt to the trend of intelligent management of gate stations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gate station traffic bridge guardrail includes a first crossbeam, a fixing block fixedly connected inside the first crossbeam, a threaded rod rotatably connected inside the fixing block, a rotating block fixedly connected to the outer wall of the threaded rod, a limit groove formed inside the fixing block, a locking block threadedly connected to the outer wall of the threaded rod, the outer wall of the locking block slidably connected to the inner wall of the limit groove, a connecting post abutting the inner wall of the locking block, the outer wall of the connecting post slidably connected to the inside of the fixing block, a water level sensor fixedly connected to the bottom end of the connecting post, the upper surface of the water level sensor being disposed on the lower surface of the fixing block, a through groove formed inside the first crossbeam, and a support assembly provided on the outer wall of the first crossbeam.

[0008] The above technical solution allows for real-time monitoring of the water level by installing the water level sensor on the inner side of the first crossbeam. Rotating the rotating block drives the threaded rod to rotate, which in turn drives the locking blocks on both sides to slide, thereby locking the connecting column and completing the installation of the water level sensor.

[0009] As a further description of the above technical solution:

[0010] The support assembly includes a U-shaped frame, the outer wall of which is welded to a first crossbeam, and a first bolt is threadedly connected to the inside of the U-shaped frame, with a column threadedly connected to the outer wall of the first bolt.

[0011] Through the above technical solution: the first crossbeam can be fixed to the U-shaped frame by welding technology, and the U-shaped frame can be quickly installed on the column by the first bolt.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the U-shaped frame is welded to the second crossbeam, and the outer wall of the U-shaped frame is welded to the third crossbeam.

[0014] Through the above technical solution, the second and third crossbeams can be fixed to the U-shaped frame by welding. Through the special positional design between the first, second, and third crossbeams, the impact force can be evenly distributed, thereby providing better protection.

[0015] As a further description of the above technical solution:

[0017] Through the above technical solution, the flange can provide stable support for the connection between the column and the base, and the second bolt can lock and fix the flange and the base, making the column more stable during use.

[0018] As a further description of the above technical solution:

[0019] The flange is internally fixedly connected to a fixing post, the fixing post is internally provided with a connecting piece, and the top of the connecting piece is fixedly connected to a knob.

[0020] Through the above technical solution: the flange plays a role in fixing the fixed column, the fixed column can provide support for the rotation and sliding of the connecting piece, the connecting piece plays a role in fixing the knob, and the connecting piece can be rotated and slid simultaneously by rotating and pressing the knob.

[0021] As a further description of the above technical solution:

[0022] The bottom end of the connecting piece is fixedly connected to a sliding column, the outer wall of the sliding column is slidably connected to the inside of the fixed column, the outer wall of the sliding column is slidably connected to the inside of the flange, and the outer wall of the sliding column is slidably connected to the inside of the base.

[0023] Through the above technical solution: the connecting plate plays a role in fixing the sliding column, and the sliding column will slide and rotate simultaneously with the sliding and rotation of the connecting plate, aligning the flange with the base, so that the sliding column can enter the interior of the base.

[0024] As a further description of the above technical solution:

[0025] A spring is slidably connected to the outer wall of the sliding column. One end of the spring is slidably connected to the inside of the fixed column, and the other end of the spring is fixedly connected to the bottom end of the connecting piece.

[0026] With the above technical solution: the spring will be squeezed due to the sliding of the slide column, and the spring will play the role of rebound and reset. When the knob is released, the connecting piece can slide in the opposite direction inside the fixed column through the rebound force of the spring.

[0027] As a further description of the above technical solution:

[0028] The sliding column is fixedly connected to a clamping rod inside. The outer wall of the clamping rod is slidably connected to the inside of the flange. The inside of the clamping rod is slidably connected to the inside of the base. The outer wall of the clamping rod is slidably connected to the inner wall of the clamping groove.

[0029] The above technical solution involves the sliding column fixing the clamp rod, which rotates and slides simultaneously with the rotation of the sliding column. When the clamp rod is engaged in the inner wall of the groove, it can limit and fix the flange and base.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the rotating block drives the threaded rod to rotate. Through the cooperation between the locking block and the connecting column, the locking block locks the connecting column, thereby installing and fixing the water level sensor.

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.

[0041] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a gate station traffic bridge guardrail, including a first crossbeam 1, a fixing block 2 fixedly connected inside the first crossbeam 1, a threaded rod 3 rotatably connected inside the fixing block 2, a rotating block 4 fixedly connected to the outer wall of the threaded rod 3, a limit groove 5 opened inside the fixing block 2, a locking block 6 threadedly connected to the outer wall of the threaded rod 3, the outer wall of the locking block 6 slidably connected to the inner wall of the limit groove 5, a connecting post 7 abutting the inner wall of the locking block 6, the outer wall of the connecting post 7 slidably connected to the inside of the fixing block 2, a water level sensor 8 fixedly connected to the bottom end of the connecting post 7, the upper surface of the water level sensor 8 being disposed on the lower surface of the fixing block 2, a through groove 9 opened inside the first crossbeam 1, and a support assembly 10 disposed on the outer wall of the first crossbeam 1;

[0042] Specifically, the through slot 9 at the bottom of the first crossbeam 1 facilitates the installation or maintenance of the water level sensor 8. The fixing block 2, fixed inside the first crossbeam 1, supports the threaded rod 3. The threaded rod 3 fixes the rotating block 4. Rotating the rotating block 4 allows the threaded rod 3 to rotate stably inside the fixing block 2. The threaded rod 3 is threadedly connected to the locking block 6, allowing the locking block 6 to slide synchronously with the rotation of the threaded rod 3. The limiting groove 5 supports and limits the sliding of the locking block 6, allowing the locking block 6 to slide against the inner wall of the limiting groove 5. The threaded rod 3 is bidirectional, allowing the locking blocks 6 on both sides to slide relative to each other, and the distance between the two locking blocks 6 can be flexibly adjusted. The water level sensor 8 is fixed to the connecting column 7, allowing the water level sensor 8 to connect to the locking block 6 through the connecting column 7. The inner wall of the locking block 6 has a groove that can engage with the connecting column 7, locking the connecting column 7 and thus fixing the position of the water level sensor 8 inside the first crossbeam 1. The water level sensor 8 is existing technology and can promptly feed back water level information to the control system.

[0043] Reference Figure 1 The support assembly 10 includes a U-shaped frame 1001, the outer wall of which is welded to the first crossbeam 1, a first bolt 1002 is threaded inside the U-shaped frame 1001, and a column 1003 is threaded to the outer wall of the first bolt 1002; the outer wall of the U-shaped frame 1001 is welded to the second crossbeam 21, and the outer wall of the U-shaped frame 1001 is welded to the third crossbeam 22.

[0044] Specifically, the U-shaped frame 1001 serves to support and fix the first crossbeam 1. The first crossbeam 1 can be welded to the U-shaped frame 1001 for protection. Similarly, the U-shaped frame 1001 also serves to fix and support the second crossbeam 21 and the third crossbeam 22. The first bolt 1002 serves to install and fix the U-shaped frame 1001 and the column 1003. The U-shaped frame 1001 and the column 1003 are fixed by the locking action of the threads. The first crossbeam 1, the second crossbeam 21 and the third crossbeam 22 are respectively set at one-quarter, one-half and three-quarters of the column 1003. By using aluminum alloy material, when it is hit by a vehicle, the aluminum alloy material absorbs kinetic energy through plastic deformation, has a long service life and can evenly disperse the impact force.

[0045] Reference Figure 1 , Figure 4 and Figure 5 A flange 11 is fixedly connected to the lower surface of the column 1003. A second bolt 12 is threaded inside the flange 11, and a base 13 is threaded to the outer wall of the second bolt 12. A groove 14 is provided inside the base 13, and the lower surface of the flange 11 is set on the upper surface of the base 13. A fixing post 15 is fixedly connected inside the flange 11. A connecting piece 16 is provided inside the fixing post 15, and a knob 17 is fixedly connected to the top of the connecting piece 16. A sliding post 18 is fixedly connected to the bottom of the connecting piece 16, and the outer wall of the sliding post 18 is slidably connected to the fixing post. Inside the fixed column 15, the outer wall of the sliding column 18 is slidably connected to the inside of the flange 11, and the outer wall of the sliding column 18 is slidably connected to the inside of the base 13; a spring 19 is slidably connected to the outer wall of the sliding column 18, one end of the spring 19 is slidably connected to the inside of the fixed column 15, and the other end of the spring 19 is fixedly connected to the bottom end of the connecting piece 16; a locking rod 20 is fixedly connected inside the sliding column 18, the outer wall of the locking rod 20 is slidably connected to the inside of the flange 11, the inside of the locking rod 20 is slidably connected to the inside of the base 13, and the outer wall of the locking rod 20 is slidably connected to the inner wall of the locking groove 14;

[0046] Specifically, flange 11 provides good stability for the connection between column 1003 and base 13. Fixed column 15, fixed inside flange 11, supports connecting piece 16. Connecting piece 16 fixes knob 17; rotating and pressing knob 17 causes connecting piece 16 to rotate and press synchronously inside fixed column 15. Connecting piece 16 fixes sliding column 18, causing sliding column 18 to rotate and slide synchronously. Spring 19, located between connecting piece 16 and fixed column 15, slides and compresses due to the sliding and rotation of connecting piece 16. Sliding column 18 fixes locking rod 20, causing locking rod 20 to rotate and slide synchronously. When the rod 20 enters the base 13 in its original state, it can be locked into the inner wall of the slot 14 by rotating and sliding it 90 degrees. The slot 14 is designed to allow the rod 20 to enter and slide out only in its original form. After rotating it 90 degrees, the position of the rod 20 can be limited and fixed. At this time, by releasing the knob 17, the spring 19 can push the rod 20 to fit against the inner wall of the slot 14. The flange 11 has a groove inside that allows the sliding column 18 and the rod 20 to slide in. The column 1003 can be installed and used by fixing the flange 11 to the base 13. The second bolt 12 can provide auxiliary support for the connection between the flange 11 and the base 13, making it more stable during use.

[0047] Working principle: When the guardrail is needed, the post 1003 and flange 11 are connected and installed with the base 13. Align the flange 11 with the base 13. During alignment, the sliding post 18 and locking rod 20 will slide into the base 13. Then, rotate and press the knob 17. The knob 17 will cause the connecting piece 16 and sliding post 18 to rotate and slide inside the fixed post 15, compressing the spring 19 during this sliding process. Rotating the knob 17 90 degrees will simultaneously rotate the locking rod 20 90 degrees. Then, release the knob 17. The spring 19's rebound action pushes the connecting piece 16 upward, causing the sliding column 18 and the locking rod 20 to slide upward simultaneously. This locks the locking rod 20 into the inner wall of the slot 14, fixing the flange 11 and the base 13. After fixing, the flange 11 and the base 13 are locked together by the second bolt 12, completing the installation of the column 1003. This enhances the stability of the column 1003 during use and allows maintenance personnel to quickly replace damaged parts through the detachable design, reducing installation and maintenance time.

[0048] After fixing the position between the column 1003 and the base 13, the U-shaped frame 1001 is locked to the column 1003 with the first bolt 1002. The first crossbeam 1, the second crossbeam 21, and the third crossbeam 22 are welded to the U-shaped frame 1001 at different positions. The water level sensor 8 is then installed by sliding it into the fixed block 2 through the connecting column 7. The rotating block 4 is rotated, which drives the threaded rod 3 to rotate. When the threaded rod 3 rotates, it causes the locking blocks 6 on both sides to slide against the inner wall of the limiting groove 5. The connecting column 7 is locked and fixed by sliding the locking blocks 6 on both sides, and the water level sensor 8 is installed inside the first crossbeam 1. The water level sensor 8 can monitor the water level information in real time, achieving the effect of integrated water level monitoring function to realize automatic alarm when the water level exceeds the standard, and facilitating its installation and maintenance. This guardrail not only achieves the effect of quick replacement of damaged parts by maintenance personnel through the detachable design, reducing installation and maintenance time, but also achieves the effect of integrated water level monitoring function to realize automatic alarm when the water level exceeds the standard, and facilitating its installation and maintenance.

[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.
