Description

Technical Field

[0001] This invention relates to the field of railway bridge pier maintenance technology, specifically a smart maintenance system for high-speed railway bridge piers. Background Technology

[0002] High-speed railway bridge piers are structures designed to support and bear the loads of high-speed railway tracks. They are formed by casting steel structures. Typically, the lower end of a high-speed railway bridge pier is an elliptical structure, while the upper two ends are outward-expanding arc-shaped structures. Connecting protrusions for connecting to the main structure are provided at both ends of the top of the bridge pier.

[0003] After the high-speed railway bridge piers are formed, they require spray curing. Currently, the main methods for high-speed railway bridge pier maintenance are as follows: 1. High-pier spray curing: In high-pier sections and areas without running water, plastic water tanks are installed on the pier top. High-pressure water pumps, in conjunction with water trucks, are used to regularly fill the tanks through hoses. Then, workers manually spray water onto the pier concrete using PVC spray pipes held at the top of the pier. 2. Low-pier spray curing: In low-pier sections with running water, hoses are directly connected to the water supply and the PVC spray pipes at the top of the pier. Controlled by ground valves, water is sprayed onto the pier concrete through the PVC spray pipes. 3. Pier wrapping curing: To avoid excessive evaporation, high or low temperatures, and uneven curing, the pier body is promptly wrapped in two layers after demolding. The inner layer uses non-woven fabric to protect against moisture, while the outer layer uses plastic film to prevent moisture loss and the effects of high and low temperatures. The outer layer is sealed with rope hoops to ensure close contact with the concrete surface and prevent it from being torn by wind. A water tank is installed on the top of the pier, and a spray pipe is installed inside the enclosure for spraying and maintenance.

[0004] The aforementioned maintenance operations for bridge piers require a large amount of manpower, making it impossible to carry out intelligent timed spraying operations. Furthermore, the spraying uniformity during maintenance is insufficient, resulting in blind spots in the maintenance of bridge piers. The sides of the bridge piers cannot be sprayed with water for maintenance. In addition, the existing spraying operation cannot securely lock the spray pipes, and the spraying angle and position need to be manually adjusted. Excessive spraying pressure can also cause the spray heads to detach. Summary of the Invention

The spraying component includes a movable component slidably connected in the arc-shaped channel and a maintenance component installed on the upper end of the movable component.

[0008] The maintenance component includes two maintenance brackets symmetrically installed on top of the movable component. A rotating block is rotatably connected between the two maintenance brackets. A supporting elastic column slides through the rotating block. A spraying bracket is connected to one end of the supporting elastic column near the pier. A guide block is installed at the other end of the supporting elastic column. An arc-shaped spraying frame is installed inside the spraying bracket. Spraying heads are evenly installed along the arc-shaped structure on one side of the spraying frame corresponding to the pier. The spraying heads are connected to the connecting pipe through the spraying pipe.

[0009] Preferably, the movable component includes a movable support slidably connected within the arc-shaped channel, a rotating shaft passing through the middle of the movable support, a gear meshing with the gear teeth of the supporting arc-shaped frame installed at the bottom of the rotating shaft, and the upper end of the rotating shaft connected to the output shaft of a rotating motor via a coupling, the rotating motor being mounted on the movable support via a motor mount.

[0010] Preferably, the opposite sides of the supporting arc frame and the clamping frame are provided with sliding grooves, the middle of the movable support is provided with a sliding plate that cooperates with the sliding groove, and the upper and lower sides of the sliding plate are provided with balls.

[0011] Preferably, a square groove is provided on the spray frame corresponding to the position of the spray head. The spray head is rotatably installed in the square groove of the spray frame via a vertical rotating shaft. An angle adjustment chain is installed on the spray bracket to adjust the spray angle of the spray head.

[0012] Preferably, the angle adjustment chain includes two vertical guide plates symmetrically installed on the front and rear sides of the spray bracket, a slidable rocking plate is connected between the two vertical guide plates, a reciprocating cylinder is connected to the rocking plate and locked on the spray bracket, and clamping frames are evenly installed on the rocking plate, which clamp the spray head on both sides of the corresponding position.

[0013] Preferably, the guiding component includes a guide buckle plate distributed on the side of the guide bracket near the pier. The guide buckle plate has an arc-shaped structure and a guide protrusion is provided on the side of the guide buckle plate corresponding to the pier.

[0014] Preferably, an adjusting screw is installed on the guide bracket by means of a threaded engagement. The end of the adjusting screw near the pier is rotatably connected to the guide buckle plate. A guide rod is provided on the guide buckle plate, and the guide rod passes through the guide bracket.

[0015] Preferably, each of the guide plates is provided with two guide protrusions, both of which are U-shaped structures and face opposite directions.

[0016] Preferably, the guide block has an arc-shaped structure, and both ends of the guide block are provided with chamfers, and the guide protrusion is used to guide the guide block.

[0017] Preferably, the intelligent maintenance system for the bridge pier further includes a central control unit. The central control unit includes a central control module, a sensor control module, a water pump control module, a motor control module, and a cylinder control module. The central control module is electrically connected to the sensor control module, the water pump control module, the motor control module, and the cylinder control module, respectively.

[0018] The beneficial effects of this invention are as follows: First, this system can perform all-round spraying and maintenance work on bridge piers of different models, increasing the effect of bridge pier maintenance and the applicability of this system. At the same time, the locking component in this system can stably lock the supporting arc-shaped frame on the upper end of the bridge pier and its top connecting protrusion, thus preventing the spray pipe from loosening or even falling off. This system uses an arc-shaped movement method for the spray head to increase the spraying range and uniformity of the spray head on the bridge pier. Moreover, the spray head can swing up and down and left and right during spraying operations, further increasing the spraying uniformity of the bridge pier by this invention.

[0019] Second, the moving component of this system is used to move the maintenance component within the arc-shaped channel, thereby enabling the maintenance component to move in an arc-shaped manner, increasing the comprehensiveness of the system's spraying of the bridge piers. The ball bearings on the sliding plate can increase the smoothness of the movement of the moving support.

[0020] Third, this system uses the reciprocating extension and retraction motion of the reciprocating cylinder to drive the swaying plate to reciprocate on two vertical guide plates. The clamping frame on the swaying plate drives the spray head to rotate back and forth. The guide block can swing up and down under the drive of the guide protrusion, so that the spray head can swing up and down synchronously, further increasing the spray uniformity of the spray head.

[0021] Fourth, this system can adjust the position of the guide plate in advance by rotating the adjusting screw according to the spraying distance of the spray head at various positions on the bridge pier. Then, when the guide block moves to the position of the guide plate, it can automatically fit with it, thereby adjusting the distance between the spray head and the bridge pier and increasing the comprehensiveness of the bridge pier spraying operation.

[0022] V. This system can automatically control the bridge piers to carry out timed spraying and maintenance operations through the central control module. It can also determine whether it is raining through the humidity sensor. Spraying and maintenance operations will not be carried out in rainy weather, and the spraying and maintenance operations will be stopped if it rains during the spraying process.

[0032] 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.

[0033] See Figure 1 A smart maintenance system for high-speed railway bridge piers includes two symmetrically locked arc-shaped support frames 1 on the upper arc-shaped structure of the bridge pier. Each arc-shaped support frame 1 is connected to a spraying component 2, and the spraying component 2 is equipped with a connecting pipe. The spraying component 2 is connected to the outlet of a water pump through the connecting pipe. The side of the arc-shaped support frame 1 corresponding to the bridge pier is provided with a locking component 3 for locking it to the bridge pier. A guide bracket 4 is installed in the middle of the other side of the arc-shaped support frame 1. The guide bracket 4 has an L-shaped cross-section, and the vertical section of the guide bracket 4 is an arc-shaped structure. Guide components 5 are evenly installed on the guide bracket 4 along its arc-shaped structure. This system can perform all-round spraying maintenance work on bridge piers of different models, increasing the effect of bridge pier maintenance and the applicability of the system. Specifically, firstly, the connecting pipe of the spraying component 2 is connected and locked to the outlet of the water pump. Then, the two arc-shaped support frames 1 are locked to the arc-shaped structures at both ends of the bridge pier through the locking component 3. After that, the water pump is started, so that the spraying component 2 can perform all-round spraying maintenance on the structure of the bridge pier.

[0034] See Figure 2The locking component 3 includes an anti-slip plate 31 connected to the side of the supporting arc frame 1, a stabilizing frame 32 sleeved on the square connecting column of the pier, and a clamping plate 33 clamped on the arc structure of the pier. The anti-slip plate 31 rests on the upper side of the pier and is connected to the stabilizing frame 32. Both the front and rear ends of the stabilizing frame 32 are telescopic adjustment structures. The clamping plate 33 is connected to the lower middle part of the supporting arc frame 1 through a top extension cylinder 34, and the clamping plate 33 is hinged to the top extension cylinder 34. The locking component 3 can lock the arc structure at the upper end of the pier. The connecting protrusion at its top further securely locks the supporting arc frame 1, increasing the stability and safety of the system during spraying and maintenance. Specifically, when it is necessary to lock the supporting arc frame 1, the supporting arc frame 1 is moved to a suitable position by hoisting, so that the stabilizing frame 32 is locked on the pier connecting protrusion and the anti-slip plate 31 is placed on the top of the pier. Then, the top extension cylinder 34 is controlled to extend, so that the clamping plate 33 is attached to the side of the arc structure at the top of the pier under the connection of the hinge.

[0035] It should be noted that the telescopic adjustment structure at both ends of the stabilizing frame 32 can be adjusted by using pins and pin holes to change its length. By changing the length of the front and rear ends of the stabilizing frame 32, the distance between the spraying component 2 and the bridge pier can be adjusted, and the system can also be adapted to different types of bridge piers.

[0036] See Figure 1 and Figure 2 The supporting arc frame 1 includes a clamping frame 11 disposed on its side away from the bridge pier. The supporting arc frame 1 and the clamping frame 11 form an arc-shaped channel. The side of the supporting arc frame 1 and the upper end of the clamping frame 11 are provided with wheel teeth. The spraying component 2 includes a moving component 6 slidably connected in the arc-shaped channel and a maintenance component 7 installed on the upper end of the moving component 6. The arc-shaped channel formed by the supporting arc frame 1 and the clamping frame 11 can limit the movement of the moving component 6.

[0037] See Figure 3 The moving component 6 includes a movable support 61 slidably connected within the arc-shaped channel. A rotating shaft 62 is provided through the middle of the movable support 61. A gear 63 is installed at the bottom of the rotating shaft 62, meshing with the gear teeth of the supporting arc-shaped frame 1. The upper end of the rotating shaft 62 is connected to the output shaft of the rotating motor 64 via a coupling. The rotating motor 64 is mounted on the movable support 61 via a motor mount. The moving component 6 is used to drive the maintenance component 7 to move within the arc-shaped channel, thereby enabling the maintenance component 7 to move in an arc-shaped manner, increasing the comprehensiveness of the system's spraying of the bridge piers. Specifically, the rotation of the rotating motor 64 drives the gear 63 to move along the gear teeth of the supporting arc-shaped frame 1, thereby driving the maintenance component 7 to move synchronously.

[0038] It should be noted that sliding grooves are provided on the opposite sides of the supporting arc frame 1 and the clamping frame 11. A sliding plate 65 that cooperates with the sliding groove is provided in the middle of the movable support 61. Ball bearings are provided on the upper and lower sides of the sliding plate 65. The cooperation between the sliding plate 65 and the sliding groove can increase the stability of the movable support 61. The ball bearings on the sliding plate 65 can increase the smoothness of the movement of the movable support 61.

[0039] See Figure 2 and Figure 3 The maintenance component 7 includes two maintenance brackets 71 symmetrically installed on the top of the movable support 61. A rotating block 72 is rotatably connected between the two maintenance brackets 71. A supporting elastic column 73 is slidably inserted into the rotating block 72. A spraying bracket 74 is connected to one end of the supporting elastic column 73 near the pier. A guide block 75 is installed at the other end of the supporting elastic column 73. An arc-shaped spraying frame 76 is installed inside the spraying bracket 74. Spraying heads 77 are evenly installed along the arc-shaped structure of the spraying frame 76 on one side corresponding to the pier. The spraying heads 77 are connected to the connecting pipe through the spraying pipe 78. The maintenance component 7 can spray the pier in different directions through the arc-shaped distributed spraying heads 77. Specifically, by turning on the water pump, the water flows through the connecting pipe and the spraying pipe 78 and is sprayed out from the spraying heads 77.

[0040] See Figure 4 and Figure 5 To increase the spray uniformity of the spray head 77, this system uses a method of rotating the spray head 77 back and forth in a cyclical manner to increase its spray uniformity and prevent spray dead zones from appearing on the bridge pier. A square groove is opened on the spray frame 76 corresponding to the position of the spray head 77. The spray head 77 is rotatably installed in the square groove opened in the spray frame 76 via a vertical rotating shaft. An angle adjustment chain is installed on the spray bracket 74, which is used to adjust the spray angle of the spray head 77.

[0041] Continue reading Figure 4 and Figure 5 The angle adjustment chain of this system adopts the following structure: the angle adjustment chain includes two vertical guide plates 741 symmetrically installed on the front and rear sides of the spray bracket 74. A slidable rocking plate 742 is connected between the two vertical guide plates 741. A reciprocating cylinder 743 is connected to the rocking plate 742. The reciprocating cylinder 743 is locked on the spray bracket 74. Clamping frames 744 are evenly installed on the rocking plate 742. The clamping frames 744 clamp the spray head 77 on both sides of the corresponding position. The reciprocating extension and retraction of the reciprocating cylinder 743 drives the rocking plate 742 to reciprocate between the two vertical guide plates 741. The clamping frames 744 on the rocking plate 742 drive the spray head 77 to rotate back and forth.

[0042] See Figure 4To increase the spraying range of the spray head 77, this invention employs a guide component 5 to adjust the distance between the spray head 77 and the bridge pier. This allows for further adjustment of the spraying range of the spray head 77 by changing the distance between the spray head 77 and the bridge pier. The guide component 5 includes guide plates 52 distributed on the side of the guide bracket 4 near the bridge pier. The guide plates 52 have an arc-shaped structure, and guide protrusions 53 are provided on the side of the guide plates 52 corresponding to the bridge pier. An adjusting screw 51 is installed on the guide bracket 4 via a threaded connection. The end of the adjusting screw 51 near the bridge pier is rotatably connected to the guide plate 52. A guide rod 54 is provided on the guide plate 52, passing through the guide bracket 4. The guide rod 54 has scale markings for precise position adjustment. Each guide plate 52 has two guide protrusions 53. All the protrusions 53 are U-shaped, and the two guide protrusions 53 face opposite directions. This arrangement allows the guide block 75 to reciprocate up and down when it comes into contact with the guide block 75. The guide component 5 can cooperate with the guide block 75 to adjust the distance between the spray head 77 and the pier. Specifically, according to the spraying distance of the spray head 77 at various positions on the pier, the position of the guide buckle 52 can be pre-adjusted by rotating the adjusting screw 51. Then, when the guide block 75 moves to the position of the guide buckle 52, it can automatically fit with it. At the same time, the supporting elastic column 73 slides and extends in the rotating block 72, thereby adjusting the distance between the spray head 77 and the pier. In addition, the guide block 75 can swing up and down under the drive of the guide protrusions 53, so that the spray head 77 can swing up and down synchronously, further increasing the spray uniformity of the spray head 77.

[0043] Understandably, when the spray head 77 moves to the side of the pier along with the movable support 61, the farther the spray head 77 is from the pier, the larger the spraying range. Therefore, the guide component 5 on the side of the pier can be adjusted individually so that the arc-shaped structure at the end of the pier and the side can be sprayed and maintained evenly.

[0044] See Figure 4 and Figure 5 Meanwhile, the guide block 75 has an arc-shaped structure, and both ends of the guide block 75 are provided with chamfers. The guide protrusion 53 is used to guide the guide block 75. The chamfers at both ends of the guide block 75 can prevent its ends from getting stuck at the ends of the guide buckle plate 52, thus preventing the movable support 61 from moving.

[0045] See Figure 7Furthermore, this invention also provides an automated control system for a smart maintenance system for bridge piers. The smart maintenance system for bridge piers also includes a central control unit 8, which includes a central control module 81, a sensor control module 82, a water pump control module 83, a motor control module 84, and a cylinder control module 85. The central control module 81 is electrically connected to the sensor control module 82, the water pump control module 83, the motor control module 84, and the cylinder control module 85, respectively. The water pump control module 83 is electrically connected to the water pump. The sensor control module 82 is electrically connected to a humidity sensor installed in the open space outside the bridge pier. The motor control module 84 is electrically connected to a rotary motor 64. The cylinder control module 85 is electrically connected to an extension cylinder 34 and a reciprocating cylinder 743, respectively. The central control module 81 can automatically control the system to perform timed spraying maintenance on the bridge piers. The humidity sensor can determine whether it is raining. Spraying maintenance will not be performed during rainy weather, and the spraying maintenance will stop when rainfall occurs during the spraying process.

[0046] The specific steps of this invention for intelligent maintenance of bridge piers are as follows:

[0047] First, adjust the length of the stabilizing frame 32 according to the size of the pier, and adjust the position of the guide plate 52 by rotating the adjusting screw 51 according to the spraying distance of the spray head 77 at various positions of the pier. Then, connect and lock the connecting pipe of the spraying component 2 to the outlet of the water pump.

[0048] The second step is to move the supporting arc frame 1 to a suitable position by hoisting, so that the stabilizing frame 32 is locked onto the pier connecting protrusion and the anti-slip plate 31 is placed on the top of the pier. The central control module 81 sends a command to the cylinder control module 85, so that the top extension cylinder 34 extends, and the clamping plate 33 is attached to the side of the arc structure at the top of the pier under the connection of the hinge.

[0049] Third, when the maintenance time arrives, if the humidity sensor detects abnormal humidity, the system will stop the current spraying maintenance operation. If the humidity sensor does not detect abnormal humidity, the central control module 81 will send commands to the water pump control module 83 and the motor control module 84 respectively, so that the rotating motor 64 and the water pump will start working. The rotation of the rotating motor 64 drives the gear 63 to move along the gear teeth set on the supporting arc frame 1, thereby driving the maintenance component 7 to move synchronously. The maintenance component 7 can spray the bridge pier in different directions through the arc-shaped spray heads 77.

[0050] Fourth, the central control module 81 sends a command to the cylinder control module 85, causing the reciprocating cylinder 743 to reciprocate and extend, driving the swaying plate 742 to reciprocate between the two vertical guide plates 741. The clamping frame 744 on the swaying plate 742 drives the spray head 77 to rotate back and forth. At the same time, when the guide block 75 moves to the position of the guide buckle plate 52, it can automatically fit with it, thereby adjusting the distance between the spray head 77 and the bridge pier. In addition, the guide block 75 can swing up and down under the drive of the guide protrusion 53, so that the spray head 77 can swing up and down synchronously, further increasing the spray uniformity of the spray head 77.

[0051] When the system performs spraying maintenance on the bridge piers, the humidity sensor detects abnormal humidity and sends a command to the sensor control module 82. The sensor control module 82 then shuts down the maintenance operation through the central control module 81.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
