[0041] In order to better explain the present invention, in order to facilitate understanding, the present invention is described in detail by specific embodiments in combination with the drawings.

[0042] Example one

[0043] As Figure 1 and Figure 2As shown, the embodiment provides a hair punching station for long and narrow concrete modules, the hair punching station comprising a moving device 1, a hair punching device 2, an operation table 4 and a plurality of auxiliary support rods 3, a plurality of long and narrow concrete modules A to be punched are respectively placed at both sides of the operation table 4 and are supported by the auxiliary support rods 3, each long and narrow concrete module A corresponds to two auxiliary support rods 3, and the two auxiliary support rods 3 are used to support the long and narrow concrete module A so that the pipeline A1 of the long and narrow concrete module A is in a vertical state.

[0044] As shown, Figure 1 the hair punching device 2 comprises a water pump unit 21, a conveying pipe 22 and a hair punching head 23, the hair punching head 23 is communicated with the water pump unit 21 through the conveying pipe 22, and in actual application, in order to match the pipelines A1 of long and narrow concrete modules A of different specifications, the hair punching head 23 is detachably connected with the conveying pipe 22 so as to replace hair punching heads 23 of different specifications. The hair punching head 23 maintains a vertical state by its own gravity, utilizes the principle of gravity self-centering, has a simple and reliable structure, does not need additional sensors or driving mechanisms to maintain the posture of the head, and reduces the manufacturing cost and complexity of the equipment.

[0045] A plurality of downwardly inclined nozzles 231 are arranged on the circumference of the hair punching head 23 to form a full-coverage jet field, when high-pressure water flows out from the downwardly inclined nozzles 231, a water curtain covering the entire circumference of the inner wall of the pipeline A1 and having strong impact force is naturally formed around the head, and then 360° dead-angle-free flushing of the inner wall of the pipeline A1 is realized. In the embodiment, the included angle between the water spraying surface of the nozzle 231 and the vertical plane is 45°.

[0046] The moving device 1 can drive the hair punching head 23 to move horizontally to align the pipe opening of the long and narrow concrete module A in the vertical direction, and drive the hair punching head 23 to move vertically along the axis direction of the pipeline A1 in the long and narrow concrete module A to perform 360° hair punching on the inner wall of the pipeline A1 in the long and narrow concrete module A from top to bottom. By arranging the moving device 1, the adaptability of the work station to different layout production lines and the degree of automation are improved, and the time for manual adjustment is reduced. As shown, Figure 1 the moving device 1 comprises a mounting column 11, a cantilever 12, a clamping jaw 14 and a winch unit 13, the cantilever 12 is sleeved on the mounting column 11 and is rotationally connected with the mounting column 11 to rotate around the mounting column 11, the winch unit 13 is slidingly connected with the cantilever 12, the winch can move along the extension direction of the cantilever 12, and then rapid and large-range positioning of the hair punching head 23 in the horizontal plane is realized. The distal end of the winch unit 13 clamps and then connects with the conveying pipe 22 through the clamping jaw 14 to drive the hair punching head 23 at the distal end of the conveying pipe 22 to move up and down.

[0047] As shown, Figure 3As shown, the gun head 23 comprises a gun head body 232 and two guide blocks 233, the gun head body 232 is adapted to the pipe A1 of the long and narrow concrete module A, and the two guide blocks 233 are respectively arranged on the opposite two side walls of the gun head body 232. As shown in Figure 4 and Figure 5 As shown, the edges of the guide blocks 233 extend out of the two side walls of the gun head body 232, and the strength of the guide blocks 233 is greater than that of the gun head body 232. The extended guide blocks 233 can be in contact or small gap fit with the inner wall of the pipe A1, effectively guiding the gun head 23 to stably descend along the axis of the pipe A1, and in the process of descending, the guide blocks 233 can remove the particles in the pipe A1 of the long and narrow concrete module A, and also prevent the gun head body 232 from directly colliding and rubbing with the inner wall of the pipe A1.

[0048] As shown in Figure 3 and Figure 5 As shown, the bottom end of the gun head body 232 is tapered to form a mounting portion, and a plurality of nozzles 231 are uniformly distributed on each side of the mounting portion in the circumferential direction. The tapered mounting portion reduces the cross-sectional area of the bottom of the gun head body 232, effectively reducing the air resistance and water flow backwash interference when moving in the long and narrow pipe A1, making the movement more smooth. At the same time, by concentrating the nozzles 231 on the tapered mounting portion, the water flow of the plurality of nozzles 231 can be more accurately converged and applied to the inner wall of the pipe A1, forming a water curtain with stronger impact force, further improving the efficiency of the gun head. It should be noted that a flow channel is provided in the interior of the gun head body 232, and the water inlets of the plurality of nozzles 231 are in communication with the flow channel.

[0049] In this embodiment, there are six nozzles 231 in the circumferential direction of the mounting portion. Specifically, on the two sides corresponding to the long sides of the rectangular cross section of the inner wall of the pipe A1 of the long and narrow concrete module A, two nozzles 231 are arranged on each side, and the two nozzles 231 on the long side are staggered to avoid interference of the fan-shaped water columns sprayed by the nozzles 231, so as to not offset the impact force and improve the efficiency of the gun head. On the two sides corresponding to the short sides, one nozzle 231 is arranged on each side. The six nozzles 231 are fixedly installed at a certain inclination angle, and the jet directions thereof cooperatively cover the circumferential direction, and jointly connect to form a complete 360° water curtain wrapping the gun head. It should be noted that in the entire gunning process, the gun head 23 is only vertically moved up and down by the moving device 1, and the gun head 23 and the nozzles 231 do not rotate. This design of forming a full-coverage water curtain by relying on fixed multiple nozzles 231 simplifies the structure of the gun head and improves the reliability of the work while ensuring the effect of washing the wool without dead angle.

[0050] As shown in Figure 4 and Figure 5As shown, the bottom of the mounting part is provided with a collision protection block 234. When the punching gun head 23 descends to the bottom of the pipe A1, the collision protection block 234 can effectively buffer the impact and absorb the collision energy, preventing the mounting part and the nozzle 231 on it from making hard contact with the bottom of the pipe A1 and being damaged.

[0051] like Figure 3 and Figure 6 As shown, the burring gun head 23 also includes multiple guide wheel units 235, which are respectively disposed on the side wall of the gun head body 232 to roll in connection with the pipe wall of the elongated concrete module A. The guide unit is located above the guide block 233. This makes the lifting and lowering of the burring gun head 23 more flexible and stable, reduces the driving load required by the moving device 1, and also avoids the burring gun head 23 scratching the inner wall of the pipe A1.

[0052] like Figure 6 As shown, multiple mounting slots 2321 are formed on the side wall of the gun head body 232. Each mounting slot 2321 corresponds to a different guide wheel unit 235. By embedding the mounting base 2351 into the mounting slot 2321, the structure becomes more compact and stable. The guide wheel unit 235 includes a mounting base 2351 and multiple rollers 2352. The rollers 2352 are arranged longitudinally along the mounting base 2351, and their rolling surfaces protrude from the side wall of the gun head body 232, making rolling contact with the wall of the narrow concrete module A. The longitudinal arrangement of the rollers 2352 forms multiple continuous line contact support points with the inner wall of the pipe A1, effectively preventing possible swaying or jamming of the punching gun head 23 during movement, ensuring the stability of the movement.

[0053] Example 2

[0054] This invention provides a roughening method for elongated concrete modules, using the roughening workstation in Embodiment 1, and includes the following steps;

[0055] S1. Multiple elongated concrete modules A to be roughened are respectively placed on both sides of the operating table 4, and the multiple elongated concrete modules A to be roughened are arranged sequentially along the length of the operating table 4.

[0056] S2. The moving device 1 drives the punch head 23 to move horizontally so as to align it with the opening of the first narrow concrete module A in the vertical direction.

[0057] S3. Start the water pump unit 21. At the same time, the moving device 1 drives the squeegee head 23 to move vertically from top to bottom along the axis of the pipe A1 of the currently aligned narrow concrete module A. The squeegee head 23 maintains a vertical state by its own weight and squeegees the inner wall of the pipe A1 in the narrow concrete module A 360°.

[0058] S4. After the punching gun head 23 moves to the bottom of the pipe A1, the moving device 1 drives the punching gun head 23 to move vertically from bottom to top along the axis of the pipe A1 of the narrow concrete module A and then detaches from the current narrow concrete module A.

[0059] S5. The moving device 1 drives the punching gun head 23 to move horizontally so as to align the pipe opening of the next narrow concrete module A to be punched in the vertical direction.

[0060] S6. Repeat steps S3-S5 until all narrow concrete modules A are roughened.

[0061] The rinsing method for the elongated concrete module A in this embodiment can sequentially rinsing the pipes A1 in the elongated concrete module A arranged on both sides of the operating platform 4, thereby improving rinsing efficiency. Simultaneously, because the rinsing gun head 23 in the rinsing workstation has multiple downward-sloping nozzles 231 around its circumference, a fully covered jet field is formed. When high-pressure water is ejected from these downward-sloping nozzles 231, it naturally forms a powerful water curtain around the nozzle, covering the entire circumference of the inner wall of the pipe A1, thus achieving 360° rinsing of the inner wall of the pipe A1 without dead angles. The moving device 1 can drive the rinsing gun head 23 to move horizontally to align it vertically with the pipe opening of the elongated concrete module A, and drive the rinsing gun head 23 to move vertically along the axis of the pipe A1 in the elongated concrete module A to perform 360° rinsing of the inner wall of the pipe A1 from top to bottom. By setting up the mobile device 1, the workstation's adaptability to different production line layouts and its level of automation are improved, reducing the time required for manual adjustments.
