Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a spray rack for pier maintenance. Background Technique

[0002] A pier is a crucial component in a bridge structure, mainly functioning to support the upper structure and transfer loads to the foundation. The pier is located between two abutments and supports the upper structure of the bridge, including the bridge deck, bridge slab, and loads such as vehicles and pedestrians traveling on it.

[0003] In the initial stage after the pier is poured, frequent spray maintenance is required. This stage usually lasts for several days, during which time it is necessary to ensure that the surface of the pier always remains wet to promote the hydration reaction of cement and the hardening process of concrete. As the concrete gradually hardens, the frequency of spray maintenance can be gradually reduced until it stops completely.

[0004] Currently, during pier maintenance, the maintenance spray rack is placed outside the circumferential wall of the pier, and a small crane is installed on the top of the pier. The spray rack is lifted up and down by the small crane in cooperation with a rope for displacement spray maintenance of the pier.

[0005] The existing technology can achieve spray maintenance of the pier, but in windy weather, when using a rope to lift the spray rack for up-and-down displacement spray maintenance, the spray rack is prone to swinging and hitting the pier, resulting in damage to the spray rack and the pier, and the safety and efficiency of pier maintenance are low. Content of the Utility Model

[0006] The purpose of the utility model is to provide a spray rack for pier maintenance to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A spray rack for pier maintenance includes a pier and a spray maintenance device for maintaining the pier. The spray maintenance device includes a maintenance spray component, a maintenance moving component, and a driving mechanism. The maintenance moving component is located on the top of the pier to be maintained, and the driving mechanism is located on the maintenance moving component.

[0009] The maintenance moving component includes a maintenance movement slide rail frame, which is arranged in an oval structure. The maintenance movement slide rail frame is located near the outer circumferential top of the maintenance pier. The top of the maintenance movement slide rail frame is provided with a movement groove, and the outer circumferential walls on both sides of the maintenance movement slide rail frame are symmetrically provided with movement limiting grooves, which are arranged in a "chuan" character structure. The inner walls around the maintenance movement slide rail frame are provided with turning grooves downstream near the top corner turning points.

[0010] As a preferred embodiment of this utility model, the driving mechanism includes a driving component and a motion component. The motion component includes a fixed plate, a driving wheel, a driven wheel, and a limiting slide plate. The driving wheel is located in the motion groove at the top of the maintenance motion slide rail frame. The fixed plate is located on the maintenance motion slide rail frame at the top of the driving wheel. The driven wheels are symmetrically located inside the motion grooves on both sides of the fixed plate. The driven wheels are connected to the bottom of the fixed plate via a bearing-connected rotating shaft. The limiting slide plate is located at the bottom of each driven wheel. The bottom of the rotating shaft at the bottom of the driven wheel is connected to the top of the limiting slide plate. The limiting slide plate is slidably connected to the motion limiting groove below the driven wheel.

[0011] As a preferred embodiment of this utility model, the drive assembly includes a drive motor, a driving bevel gear, a driven bevel gear, and a shaft. The drive wheel is connected through the shaft. Both ends of the shaft are connected to the bottom of the fixed plate through bearing seats. One end of the shaft extends through the bearing seat to the outside and is connected to the driven bevel gear. The driving bevel gear meshes with the driven bevel gear on one side. The output end of the drive motor is connected to the driving bevel gear. The drive motor is fixedly located at the bottom of the fixed plate.

[0012] As a preferred embodiment of this utility model, the maintenance spraying assembly includes a spray pipe, which is vertically installed at the bottom of the fixing plate outside the bridge pier, near the bottom of the outer edge. Spray heads are uniformly connected to the outer wall of the spray pipe on the side near the bridge pier, and the top of the spray pipe is connected to the maintenance water supply motor through a pipeline.

[0013] As a preferred embodiment of this utility model, the drive motor is electrically connected to an external maintenance controller via a wire.

[0014] As a preferred embodiment of this utility model, a horizontal counterweight is provided on the top of the side of the fixing plate away from the spray pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In response to the problems mentioned in the background art, this application introduces a drive mechanism and motion components to achieve automated control and stable movement of the spray frame, thereby effectively improving the safety and efficiency of bridge pier maintenance;

[0017] The maintenance movement slide rail frame with an elliptical structure is fixed to the top of the pier, which has high stability. The combination of drive wheels, driven wheels and limit slide plates ensures that the spray pipe moves stably outside the outer circumference of the pier and will not be affected by the swinging in windy weather, causing impact damage to the pier.

[0018] After receiving the start signal, the drive motor begins to work, and its output drives the active bevel gear to rotate. The active bevel gear interacts with its meshing driven bevel gear, causing the driven bevel gear to also start rotating. The rotation of the driven bevel gear is transmitted to the drive wheel through the shaft, causing the drive wheel to move within the motion groove. As the drive wheel moves, the entire spray curing device moves horizontally along the motion groove at the top of the curing motion slide frame. The spray pipes follow the drive wheel to perform circumferential spraying motion on the outer circumferential wall of the pier. The design of the driven traveling wheel and the limiting slide plate ensures the stability and accuracy of the drive wheel during movement. The curing water supply motor starts to work, delivering water to the spray pipes through pipelines. The water flows from the spray pipes through evenly distributed spray heads, providing uniform spray curing to the pier. This efficient and stable spray curing operation on the pier improves curing efficiency and quality.

Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosed content of the present utility model more thorough and comprehensive.

[0029] Embodiment

The control circuit of the controller can be realized by simple programming by those skilled in the art and belongs to the common knowledge in this field. Therefore, this application will not be explained in detail.

[0031] Please refer to Figure 1-7 , the present utility model provides a technical solution: a spray rack for pier maintenance, including a pier 1 and a spray maintenance device 2 for maintaining the pier 1. The spray maintenance device 2 includes a maintenance spray component 23, a maintenance moving component 21, and a driving mechanism 22. The maintenance moving component 21 is located on the top of the pier 1 to be maintained, and the driving mechanism 22 is located on the maintenance moving component 21; the maintenance moving component 21 includes a maintenance movement slide rail frame 201, the maintenance movement slide rail frame 201 is arranged in an oval structure, the maintenance movement slide rail frame 201 is located at the top of the outer circumference of the maintenance pier 1, a movement groove 211 is opened at the top of the maintenance movement slide rail frame 201, and movement limit grooves 212 are symmetrically opened on the outer circumferential walls on both sides of the maintenance movement slide rail frame 201. The movement limit grooves 212 are arranged in a 'Sichuan' character structure, and turning grooves 213 are opened at the downstream of the inner walls around the four corners of the maintenance movement slide rail frame 201 near the turning points.

[0032] It should be noted that in this embodiment, the maintenance movement slide rail frame 201 is arranged in an oval structure, located at the top of the outer circumference of the maintenance pier 1. A movement groove 211 is opened at the top of the maintenance movement slide rail frame 201, and the movement groove 211 is used to accommodate the driving wheel 222 to move inside it. Movement limit grooves 212 are symmetrically opened on the outer circumferential walls on both sides of the maintenance movement slide rail frame 201, and turning grooves 213 are opened at the downstream of the inner walls around the four corners near the turning points. The movement limit grooves 212 limit the horizontal movement of the driving wheel 222 inside the movement groove 211 to ensure the smoothness of the movement. The turning grooves 213 are to ensure that the driving wheel 222 is not restricted by the structure at the turning point when turning, and ensure smooth turning.

[0033] Please refer to Figure 2 , 34. The drive mechanism 22 includes a drive component and a motion component. The motion component includes a fixed plate 221, a drive wheel 222, a driven wheel 223, and a limiting slide plate 224. The drive wheel 222 is located in the motion groove 211 at the top of the maintenance motion slide rail 201. The fixed plate 221 is located on the maintenance motion slide rail 201 at the top of the drive wheel 222. The driven wheel 223 is symmetrically located inside the upper part of the motion groove 211 on both sides of the fixed plate 221. The inside of each driven wheel 223 is connected to the bottom of the fixed plate 221 by a rotating shaft connected to the inside of the fixed plate 221 through a bearing. The limiting slide plate 224 is located at the bottom of each driven wheel 223. The bottom of the rotating shaft at the bottom of the driven wheel 223 is connected to the top of the limiting slide plate 224. The limiting slide plate 224 is slidably connected to the motion limiting groove 212 below the driven wheel 223.

[0034] The drive assembly includes a drive motor 225, a driving bevel gear 226, a driven bevel gear 227, and a shaft 228. The drive wheel 222 is connected through and located on the shaft 228. Both ends of the shaft 228 are connected to the bottom of the fixed plate 221 through bearing seats. One end of the shaft 228 extends through the bearing seat to the outside and is connected to the driven bevel gear 227. The driving bevel gear 226 is engaged with the driven bevel gear 227 on one side. The output end of the drive motor 225 is connected to the driving bevel gear 226. The drive motor 225 is fixedly located at the bottom of the fixed plate 221. A horizontal counterweight is provided on the top of the fixed plate 221 on the side away from the spray pipe 231. The drive motor 225 is electrically connected to an external maintenance controller through wires.

[0035] It should be noted that in this embodiment, the fixed plate 221 is located on the maintenance motion slide rail 1 on top of the drive wheel 222, the drive wheel 222 is located in the motion groove 211, and the driven wheels 223 are symmetrically located on both sides of the fixed plate 221 in the upper part of the motion groove 211. Each driven wheel 223 is connected to the bottom of the fixed plate 221 by a rotating shaft connected to the fixed plate 221 through a bearing. The limiting slide plate 224 is located at the bottom of each driven wheel 223 and is slidably connected to the motion limiting groove 212 below the driven wheel 223. The limiting slide plate 224 ensures the stability and accuracy of the driven wheel 223 during movement, avoiding swaying and impact. When the drive wheel 222 moves inside the motion groove 211, the driven wheel 223 is limited to rolling inside the motion limiting groove 212, and the limiting slide plate 224 is limited to sliding at the bottom of the motion limiting groove 212. The stability is high and the movement is smooth.

[0036] Furthermore, the two ends of the shaft 228 are connected to the bottom of the fixed plate 221 through bearing seats. When the drive wheel 222 rotates, it drives the fixed plate 221 connected to its shaft 228 to move. After receiving the start signal, the output end of the drive motor 225 drives the active bevel gear 226 to rotate. The active bevel gear 226 interacts with the driven bevel gear 227 it meshes with, causing the driven bevel gear 227 to also start rotating. The rotation of the driven bevel gear 227 is transmitted to the drive wheel 222 through the shaft 228, causing the drive wheel 222 to move in the motion groove 211. As the drive wheel 222 moves, the entire spraying and curing device 2 moves horizontally along the motion groove 211 at the top of the curing motion slide rail frame 201. The spray pipe 231 follows the drive wheel 222 to perform circumferential spraying motion on the outer circumferential wall of the pier 1. The design of the driven walking wheel 223 and the limiting slide plate 224 ensures the stability and accuracy of the drive wheel 222 during its movement.

[0037] Furthermore, a horizontal counterweight is provided on the top of the side of the fixing plate 221 away from the spray pipe 231. The horizontal counterweight ensures that the weight of the spray pipe 231 connected to the outer wall of the fixing plate 221 is basically the same as that of the horizontal counterweight, thus ensuring the smooth and stable spraying motion.

[0038] The external maintenance controller can adjust the speed and direction of the drive motor 225 as needed to control the movement speed and spray range of the spray frame. At the same time, the controller can also monitor the operating status of the entire system to ensure the smooth operation of the spraying operation.

[0039] Please see Figure 2 , 3 4. The maintenance spraying assembly 23 includes a spray pipe 231. The spray pipe 231 is vertically installed at the bottom of the outer fixing plate 221 of the pier 1, near the bottom of the outer edge. Spray heads 232 are evenly connected to the outer wall of the spray pipe 231 on the side near the pier 1. The top of the spray pipe 231 is connected to the maintenance water supply motor through a pipeline.

[0040] It should be noted that in this embodiment, the spray pipe 231 is vertically installed at the bottom of the outer fixing plate 221 of the bridge pier 1, near the bottom of the outer edge. When the fixing plate 221 moves with the drive wheel 222, it drives the spray pipe 231 to move on the outer circumferential wall of the bridge pier 1 to carry out spraying and curing. Water flows from the spray pipe 231 through the evenly distributed spray heads 232 to carry out uniform spraying and curing of the bridge pier 1.

[0041] The working process of this utility model:

[0042] During use, the external maintenance controller sends a start signal to the drive motor 225 via a wire. Upon receiving the start signal, the drive motor 225 begins to work, and its output drives the active bevel gear 226 to rotate. The active bevel gear 226 interacts with the driven bevel gear 227, causing the driven bevel gear 227 to also begin to rotate. The rotation of the driven bevel gear 227 is transmitted to the drive wheel 222 through the shaft 228, causing the drive wheel 222 to move within the motion groove 211. As the drive wheel 222 moves, the entire spray maintenance device 2 moves horizontally along the motion groove 211 at the top of the maintenance motion slide rail 201, causing the spray pipe 231 to move on the outer circumferential wall of the pier 1. The maintenance water supply motor starts to work, delivering water to the spray pipe 231 through the pipeline. The water flows from the spray pipe 231 through the evenly distributed spray heads 232, providing uniform spray maintenance for the pier 1.

[0043] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
