[0001] The utility model relates to the technical field of pipeline dredging, in particular to a bridge prestressed pipeline dredging device. Background Art

[0002] During the on-site construction of bridges, prefabrication, pouring and other processes are required. In order to ensure the safety and stability of the bridge structure, it is generally necessary to lay prestressed pipes during the pouring process. However, when concrete is poured, if there is any improper protection, concrete, mortar and other materials will directly enter the pipe, causing blockage and affecting the subsequent construction progress and efficiency.

[0003] In the related art, the cleaning is usually carried out by opening holes, which requires chiseling out the concrete from the beam to the prestressed pipe, removing the debris in the pipe, rewrapping the pipe and repairing the grooves of the beam. This method is very harmful to the concrete structure, easily forming shrinkage cracks, and also damaging the pipe body of the prestressed pipe, reducing its service life.

[0004] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes the prior art known to those skilled in the art.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Such as Figures 1 to 3The bridge prestressed pipe dredging device shown comprises: a cleaning mechanism 10 and a driving mechanism 20, the driving mechanism 20 is connected to the cleaning mechanism 10 and is used to provide power to the cleaning mechanism 10, the cleaning mechanism 10 comprises a drill bit 11 and a drill rod 12, the driving mechanism 20 and the drill bit 11 are detachably connected to both ends of the drill rod 12 respectively;

[0027] Among them, the drill rod 12 is a flexible rod, and the drill bit 11 is contracted at one end away from the drill rod 12 to form a pointed cone shape. The drill rod 12 and the drill bit 11 are both hollow inside to form a diversion channel 11a. The side wall of the drill bit 11 is provided with a plurality of drill holes 11b inclined toward the pointed cone end, and each drill hole 11b is connected to the diversion channel 11a.

[0028] The utility model provides a conical drill bit 11, which makes it easy for the dredging device to enter the prestressed pipe from the end of the prestressed pipe and deeply advance to perform the dredging work, thereby avoiding damage to the pipe body caused by hole opening and cleaning; and through the design of the diversion channel 11a and the diversion hole, the drill bit 11 can be cooled during the dredging and cleaning process, thereby avoiding damage to the drill bit 11 and extending the service life; and by providing the drill rod 12 as a flexible rod, when the drill bit 11 passes through hard and difficult-to-remove debris, the flexible rod can vibrate with the rotation of the drill bit 11, so that the debris in the pipe can be moved and easily removed, thereby ensuring the cleaning effect of the debris in the prestressed pipe, avoiding damage to the pipe body of the prestressed pipe, and ensuring the construction quality and efficiency.

[0029] It should be noted that the detachable drill bit 11 can select a drill bit 11 of a suitable size according to the diameter of the prestressed pipe, thereby improving the dredging efficiency and effect; the length of the drill rod 12 can also be determined according to the distance between the debris in the pipeline and the end face of the pipeline, and is not specifically limited here, thereby avoiding the drill rod 12 being too long to affect the cleaning effect of the drill bit 11, or the drill rod 12 being too short to make it difficult for the drill bit 11 to reach the location of the debris. It has strong adaptability and wide application.

[0030] On the basis of the above embodiment, the axis of the drill hole 11b forms an acute angle with the axis of the drill bit 11. As the drill bit 11 rotates, the cooling liquid in the guide channel 11a can be directly thrown out through the drill hole 11b, making it easier to reach the area where the drill bit 11 contacts the blockage, thereby improving the cooling effect, reducing the heat generated by friction, and reducing the wear of the drill bit 11 during the dredging process, thereby extending the service life of the drill bit 11.

[0031] On the basis of the above embodiment, a plurality of punching holes 11d are provided on the side wall of the drill bit 11, which are away from the pointed cone end. Each punching hole 11d is connected to the guide channel 11a. The design of the punching holes 11d can flush the debris generated by the sundries during the dredging process, so that the debris can be discharged toward the pipe port following the flow of the coolant, thereby reducing the possibility of debris accumulation near the drill bit 11, thereby avoiding the jamming or damage of the drill bit 11 due to the accumulation of debris, and providing space for the drill bit 11 to continue moving inward.

[0032] Based on the above embodiment, the aperture of the punching hole 11d is larger than the aperture of the drilling hole 11b; the debris and coolant generated during the drilling process of the hole 11b can be discharged more effectively, which helps the coolant mixed with the debris to flow more smoothly and improve the cooling effect.

[0033] On the basis of the above embodiment, a positioning block 11c is protrudingly provided on the outer surface of the drill bit 11, and the length direction of the positioning block 11c is along the axial direction of the drill bit 11. The positioning block 11c provides an additional reference point when the operator assembles the drill bit 11, which is convenient for determining whether the drill bit 11 is assembled to the specified position. When the drill bit 11 is sent into the pipeline, the relative position between the drill bit 11 and the debris can be determined by the orientation of the positioning block 11c, and positioning can be performed to avoid the drill bit 11 from deflecting or twisting in the pipeline, thereby ensuring the accuracy and safety of the dredging operation.

[0034] On the basis of the above-mentioned embodiment, a thread is provided on the inner side surface of the drill bit 11 close to one end of the drill rod 12, and the drill bit 11 is connected to the outer side surface of the end of the drill rod 12 by a thread; the threaded connection structure of the drill bit 11 and the drill rod 12 ensures the firmness of the connection between the two, reduces the loose connection caused by vibration or pressure during the dredging operation, and enables quick installation and disassembly, thereby improving the operation efficiency.

[0035] On the basis of the above embodiment, the driving mechanism 20 includes a bracket 21, a power unit 22 and a conveying unit 23. The power unit 22 and the conveying unit 23 are both arranged on the bracket 21, and the driving unit is detachably connected to the drill rod 12. The conveying unit 23 is connected to the guide channel 11a. The power unit 22 and the conveying unit 23 are integrated on the bracket 21, which is convenient for centralized control and storage. The detachable connection design between the driving unit and the drill rod 12 makes it possible to quickly replace the drill rod 12 or adjust the length of the drill rod 12 according to actual conditions during the dredging operation, thereby improving the flexibility and adaptability of the operation. The conveying unit 23 can convey cooling liquid into the guide channel 11a while the drill bit 11 is working, thereby ensuring the cooling effect on the drill bit 11.

[0036] Based on the above embodiments, the power unit 22 includes a motor 22a and a drive rod 22b. The motor 22a is fixedly arranged on the bracket 21. The drive rod 22b is hollow and is arranged parallel to the axis of the drill rod 12 in the axial direction. One end of the drive rod 22b is connected to the output end of the motor 22a, and the other end is detachably connected to the end of the drill rod 12 away from the drill bit 11. The motor 22a is directly fixed on the bracket 21, which can provide a stable power source to ensure the efficiency and stability of power transmission. The hollow setting of the drive rod 22b reduces the weight of the overall device, and at the same time ensures that the cooling liquid can be transported through the hollow drive rod 22b to the diversion channel 11a and then reach the position where the drill bit 11 is located.

[0037] It should be noted that when the length is sufficient, the drill bit 11 can also be directly screwed onto the top of the drive rod 22b without using the drill rod 12. At this time, only the outer shaft surface of the end of the drive rod 22b needs to be set as a threaded structure to achieve the screwing effect between the drive rod 22b and the drill bit 11.

[0038] Based on the above embodiments, the conveying unit 23 includes a pump body 23a and a receiving cavity 23b. The length direction of the receiving cavity 23b is arranged along the axis of the drive rod 22b. The pump body 23a and the drive rod 22b are respectively located at both ends of the receiving cavity 23b and are respectively communicated with the middle cavity of the receiving cavity 23b. The pump body 23a and the drive rod 22b are respectively located at both ends of the receiving cavity 23b, making the structure of the entire conveying unit 23 compact, facilitating integration onto the bracket 21, saving space, and ensuring that the cooling liquid is directly conveyed from the pump body 23a to the drive rod 22b to ensure the conveying efficiency.

[0039] Based on the above embodiments, the bracket 21 includes a support plate 21a and support legs. There are three support legs, which are arranged at equal intervals on the bottom edge of the support plate 21a. The motor 22a is fixedly arranged at the bottom of the support plate 21a and is located between the three support legs. The receiving cavity 23b is fixedly arranged on the top surface of the support plate 21a. The equal-spacing arrangement of the three support legs provides a stable triangular support structure, enhancing the stability of the entire device, reducing the deformation or damage of the bracket 21 caused by uneven stress, facilitating movement and transportation, and enabling the operator to easily adjust the position of the dredging device.
