Description

Technical Field

[0001] This utility model relates to the field of modular building technology, and in particular to a punching gun head for concrete modular pipes. Background Technology

[0002] With the rapid development of national industrial technology and the prefabricated building industry, various concrete modules with narrow pipes are being used more and more widely. In these modules, the pipes typically serve as the bonding surface for the poured concrete, and are crucial for ensuring the overall structural connection performance. To enhance the connection strength, the inner wall of the pipe needs to be roughened to obtain a rough interface.

[0003] Existing technologies often use single-nozzle brushing guns for brushing operations. However, the gun head is difficult to penetrate into the narrow inner cavity of pipes, and a single nozzle cannot achieve 360° full coverage of the inner wall. The operation must be carried out by repeatedly adjusting the angle, resulting in low brushing efficiency and uneven results. Utility Model Content

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this utility model are:

[0018] This invention relates to a roughening gun head for concrete modular pipes, comprising a gun head body and multiple nozzles. The gun head body can extend into the concrete modular pipe, and the multiple nozzles are arranged circumferentially along the gun head body, with each nozzle inclined downwards relative to the axis of the gun head body. A flow channel is formed inside the gun head body, and the water inlets of the multiple nozzles are connected to the flow channel.

A single insertion into the pipe completes the roughening of the entire cross-section of the inner wall, eliminating the need for repeated insertion, withdrawal, and rotation of the gun head, thus improving work efficiency. Furthermore, integrating multiple nozzles into a single gun head body results in a compact overall structure, allowing for easy insertion and operation in various narrow and elongated concrete modular pipes.

[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment of the utility model provides a burring gun head for concrete module pipes. The burring gun head includes a gun head body 2 and multiple nozzles 1. The gun head body 2 is adapted to the pipe A1 and can extend into the pipe A1 of the concrete module A. The multiple nozzles 1 are arranged circumferentially along the gun head body 2, and the multiple nozzles 1 are inclined downward relative to the axis of the gun head body 2. In this embodiment, the angle between the water spray surface of the nozzle 1 and the axis of the gun head body 2 is 30°-60°, preferably 45°.

[0028] Multiple nozzles 1 are integrated into a single nozzle body 2, resulting in a compact structure that allows for easy insertion and operation within various narrow concrete modules A and pipes A1. The nozzle body 2 has an internal flow channel 22, through which the inlets of the multiple nozzles 1 connect. The water jets from the multiple nozzles 1 collectively cover the entire cross-section of the inner wall of pipe A1, forming a continuous water curtain for 360° thorough rinsing. The circumferentially arranged nozzles 1 cover the entire circumference of the inner wall of pipe A1 in a single operation, avoiding the blind spots caused by the need for multiple reciprocating movements and angle adjustments required by single nozzles in existing technologies. A single insertion into pipe A1 completes the roughening of the entire cross-section of the inner wall, eliminating the need for repeated insertion, withdrawal, and rotation of the nozzle, thus improving operational efficiency. In actual operation, a moving device drives the nozzle body 2 from top to bottom to roughen the entire pipe A1.

[0029] In this embodiment, the nozzle body 2 is rectangular and adapts to the rectangular pipe A1. The rectangular bottom of the nozzle body 2 tapers to form a frustum-shaped mounting portion 23, and multiple nozzles 1 are evenly distributed on each side of the mounting portion 23 in the circumferential direction. The tapered mounting portion 23 reduces the cross-sectional area of ​​the bottom of the nozzle body 2, effectively reducing air resistance and water splash interference when moving within the narrow pipe A1, making the movement smoother. At the same time, concentrating the nozzles 1 on the tapered mounting portion 23 allows the water flow from multiple nozzles 1 to converge more accurately and act on the inner wall of the pipe A1, forming a water curtain with stronger impact, further improving the rinsing efficiency.

[0030] like Figure 3As shown, in this embodiment, the mounting part 23 has six nozzles 1 arranged circumferentially. Specifically, two nozzles 1 are arranged on each of the two sides corresponding to the long side of the rectangular cross-section of the inner wall of the pipe A1 of the narrow concrete module A. The two nozzles 1 on the long side are staggered to avoid interference from the fan-shaped water jets sprayed by the nozzles 1, thus preventing them from canceling each other out and improving the rinsing effect. One nozzle 1 is arranged on each of the two sides corresponding to its short side. These six nozzles 1 are fixedly installed at a specific angle, and their jet direction covers the circumferential direction in a coordinated manner, forming a complete 360° water curtain that surrounds the nozzle head. It should be noted that during the entire rinsing process, the rinsing nozzle head is only driven by the moving device to move vertically up and down, and neither the nozzles 1 nor the nozzle head rotates. This design, which relies on fixed multiple nozzles 1 to form a full-coverage water curtain, simplifies the nozzle head structure and improves the reliability of the operation while ensuring a thorough rinsing effect.

[0031] like Figure 1 As shown, the punching gun also includes two guide blocks 3, which are respectively disposed on two opposite sides of the gun head body 2 along its width direction. The length of the guide block 3 is greater than the length of the gun head body 2, that is, the edge of the guide block 3 extends out of the side walls of the gun head body 2, and the strength of the guide block 3 is greater than the strength of the gun head body 2. The protruding guide block 3 can form contact or small gap fit with the inner wall of the pipe A1, effectively guiding the punching gun head to descend smoothly along the axis of the pipe A1. During the descent, the guide block 3 can remove particles inside the narrow concrete module A pipe A1, while also preventing direct collision and friction between the gun head body 2 and the inner wall of the pipe A1.

[0032] like Figure 3 As shown, the bottom of the mounting part 23 is provided with a collision protection block 4. When the punching gun head descends to the bottom of the pipe A1, the collision protection block 4 can effectively buffer the impact and absorb the collision energy, preventing the mounting part 23 and the nozzle 1 on it from making hard contact with the bottom of the pipe A1 and being damaged.

[0033] like Figure 2 and Figure 4 As shown, the burring gun head also includes multiple guide wheel units 5, which are respectively disposed on the side wall of the gun head body 2 to roll in connection with the pipe wall of the concrete module A. The guide unit is located on the upper part of the guide block 3. This makes the lifting and lowering of the burring gun head more flexible and stable, reduces the driving load required by the moving device, and also avoids the burring gun head scratching the inner wall of the pipe A1.

[0034] like Figure 4As shown, multiple mounting slots 21 are provided on the side wall of the gun head body 2. Each mounting slot 21 corresponds to a different guide wheel unit 5. By embedding the mounting base 51 into the mounting slot 21, the structure becomes more compact and stable. The guide wheel unit 5 includes a mounting base 51 and multiple rollers 52. The rollers 52 are arranged sequentially along the longitudinal direction of the mounting base 51, and the rolling surfaces of the rollers 52 protrude from the side wall of the gun head body 2 and roll in contact with the wall of the narrow concrete module A. The longitudinal arrangement of the rollers 52 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 during movement and ensuring the stability of the movement.
