Description

Technical Field

[0001] This utility model relates to the field of railway sleeper processing technology, specifically a water jet lifting and rotating nozzle for roughening railway sleepers in ballastless tracks. Background Technology

[0002] During the use of twin-block ballastless track, cracks tend to extend outward from the four corners of the sleepers in the cast-in-place monolithic track bed. With the erosion of rainwater, these micro-cracks will gradually form through cracks. Therefore, it is necessary to use a chiseling water jet to process the sleepers.

[0003] In existing sleeper roughening devices, sleepers are transported via a conveyor belt and then roughened by high-pressure water jets. During the process, the nozzles adjust their height by oscillating as they spray water onto the sleepers, resulting in varying angles of water contact and spraying forces. This leads to uneven roughening, affecting subsequent performance and reducing the nozzles' practicality. Optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a water jet lifting and rotating nozzle for roughening sleepers in ballastless tracks, so as to solve the problem mentioned in the background art that it is difficult to stably adjust the spray height of the nozzle on the sleeper and to ensure the uniformity of the roughening of the sleeper.

The height detection assembly includes a connecting plate, a position sensor is installed at the top of the connecting plate, and a fitting pressure plate is provided at the bottom of the connecting plate. The height detection assembly is used for detecting the height of the sleeper.

The top of the adjustment screws 8 is connected to a rotary motor 10. A spray head 13 is provided on one side of the rotary motor 10. The spray adjustment component is used to adjust the position of the chiseling spray. Specifically, such as Figure 2 As shown, the inner side of the limiting plate 3 is provided with an adjustment groove 4, which is elliptical and limits the adjustment position of the mounting base 12. The bottom end of the limiting plate 3 is connected to a bottom support block 5, which is used to support the bottom of the structure.

[0019] Specifically, such as Figure 2 As shown, the drive wheel 6 is installed in the middle of the inner side of the bottom support block 5, and the outer side of the drive wheel 6 is connected to the grooved transmission belt 7. The drive wheel 6 drives the grooved transmission belt 7 to rotate, and the grooved transmission belt 7 drives the driven wheels 9 on both sides to rotate.

[0020] Specifically, such as Figure 3 As shown, the adjusting screw 8 is slidably connected to both ends of the inner side of the bottom support block 5, and the outer side of the adjusting screw 8 is threadedly connected to the driven wheel 9, which is rotatably connected to the bottom support block 5. The driven wheel 9 is composed of gears and bearings, and when assembled, the driven wheel 9 and the bottom support block 5 are rotatably connected.

[0021] Specifically, such as Figure 3As shown, a telescopic rod 11 is fixedly connected to the top of the rotating motor 10. The top of the telescopic rod 11 is fixedly connected to the top of the inner wall of the protective cover 1, which facilitates guiding and limiting the installation position of the rotating motor 10.

[0022] Specifically, such as Figure 3 As shown, a mounting base 12 is connected to one rotating end of the rotating motor 10, and a spray head 13 is installed on one side of the mounting base 12.
