Technical Field

[0001] The present application relates to the field of concrete cleaning equipment, and in particular to a corbel concrete breaking device and a construction method thereof. Background Art

[0002] In the current water-damaged reservoir repair project, the corbel is an important force-transmitting structure, and the importance of corbel repair is self-evident. In the process of corbel repair, there is a problem that the corbel concrete needs to be broken cleanly without damaging the original steel bars.

[0003] In the process of pouring concrete, the specifications usually require that the steel bars and concrete be tightly combined and vibrated to be dense without bubbles. The concrete pouring of key parts such as the corbel must be particularly dense. Therefore, it is a waste of manpower and a long operation time for operators to manually remove the concrete of the corbel without damaging the steel bars. Summary of the invention

And when it is necessary to jet in a direction parallel to the axis of the gun barrel, the DC nozzle is turned on and the jet is passed through the DC nozzle. When it is necessary to crush the concrete on one side of the hole in the concrete, the DC nozzle is turned off and the side flow nozzle is turned on. At the same time, the nozzle part is rotated through the adjustment mechanism, and then the angle of the side flow nozzle is adjusted, so that the concrete at the required position is crushed by the side flow nozzle. Human resources are saved and the operation time is shortened.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0029] The present application embodiment discloses a device for breaking corbel concrete. Figure 1 and Figure 2 The breaking device includes a spray gun body 1, and the spray gun body 1 includes a gun handle 11, a gun rod 12 and a water outlet 13. The gun rod 12 is fixed on the gun handle 11, and the water outlet 13 is fixed at one end of the gun rod 12 away from the gun handle 11. A nozzle component 2 is installed on the water outlet 13. The nozzle component 2 includes a DC nozzle 21 coaxially arranged with the gun handle 11, and also includes a side flow nozzle 22 fixedly connected to the side wall of the DC nozzle 21. Solenoid valves are respectively installed inside the DC nozzle 21 and the side flow nozzle 22, and the opening and closing of the DC nozzle 21 and the side flow nozzle 22 can be controlled by these solenoid valves.

[0030] An adjusting mechanism 3 for controlling the rotation of the nozzle member 2 is installed on the gun rod 12, thereby accurately adjusting the jet direction of the side stream nozzle 22.

[0031] One end of the nozzle member 2 close to the water outlet 13 is rotatably connected to a receiving pipe 23, and the receiving pipe 23 is coaxially arranged with the nozzle member 2. The receiving pipe 23 is sleeved on the outside of the water outlet 13, and the receiving pipe 23 and the water outlet 13 are connected by threads. This design simplifies the disassembly and assembly process of the nozzle member 2, making the maintenance or replacement of the nozzle member 2 easy and simple.

A support rod 32 is fixedly connected to the outer wall of the sleeve 31. The support rod 32 is arranged perpendicular to the axis of the sleeve 31, and a locking rod 33 is hingedly connected to one end of the support rod 32 away from the sleeve 31. A rotating shaft 34 is fixedly connected to one end of the locking rod 33, and a hinge groove 321 is provided at the upper end of the support rod 32. The rotating shaft 34 is placed in the hinge groove 321, and each end of the rotating shaft 34 is rotatably connected to the corresponding side wall of the hinge groove 321. Torsion springs 35 are sleeved at both ends of the rotating shaft 34, and one end of each torsion spring 35 is fixedly connected to the locking rod 33, and the other end is fixedly connected to the side wall of the hinge groove 321.

[0033] A locking groove 211 is formed on the outer wall of the nozzle member 2, and a locking head 36 is formed at one end of the locking rod 33 close to the nozzle member 2. The locking rod 33 rotates toward the locking groove 211 until the locking head 36 is plugged into the locking groove 211, and each torsion spring 35 provides a force for the locking head 36 to be plugged into the locking groove 211.

[0034] Reference Figure 2 , Figure 3 and Figure 4A mounting block 37 is slidably connected to the outer wall of the sleeve 31, and a guide rod 38 is fixedly connected to the side of the mounting block 37 close to the support rod 32. The end of the guide rod 38 away from the mounting block 37 penetrates the support rod 32. A guide spring 39 is sleeved on the outer wall of the guide rod 38. One end of the guide spring 39 abuts against the mounting block 37, and the other end abuts against the support rod 32. A mounting groove 331 is formed on the side of the locking rod 33 close to the mounting block 37. When the guide spring 39 is in a normal state, the mounting groove 331 is located between the mounting block 37 and the support rod 32.

[0035] At this time, the mounting block 37 is located on the side of the mounting groove 331 away from the support rod 32, and the locking rod 33 is pressed against the mounting block 37 by the force of the torsion spring 35. At this time, the locking mounting block 37 can provide a stable supporting force for the locking rod 33, so that the locking head 36 can be separated from the locking groove 211, thereby facilitating the disassembly and assembly of the nozzle component 2.

[0036] The guide rod 38 is pulled away from the locking head 36, and the guide rod 38 drives the mounting block 37 to move until the mounting block 37 is aligned with the mounting groove 331. The locking rod 33 is rotated by the force of the torsion spring 35 until the locking head 36 is plugged into the locking groove 211. At this time, the mounting block 37 is plugged into the mounting groove 331, and the guide rod 38 is released. The mounting block 37 is pressed against a side wall of the mounting groove 331 close to the locking head 36 by the elastic force of the guide spring 39.

[0037] A limiting block 381 is coaxially fixedly connected to the side wall of the guide rod 38 . When the limiting block 381 contacts a side wall of the support rod 32 away from the mounting block 37 , the mounting block 37 is located at a side of the mounting groove 331 away from the support rod 32 .

The mounting ring 4 is located between the gun handle 11 and the sleeve 31, and two connecting rods 5 are fixedly connected between the mounting ring 4 and the sleeve 31.

[0039] Reference Figure 2 and Figure 5 When the angle of the nozzle part 2 needs to be adjusted, the mounting ring 4 only needs to be rotated, and the sleeve 31 can be driven to rotate through the connecting rod 5, and then the nozzle part 2 can be driven to rotate through the locking rod 33. The mounting ring 4 is also connected to a locking assembly 6 for locking the mounting ring 4 and the gun rod 12. In this way, after the angle of the nozzle part 2 is adjusted, the mounting ring 4 and the gun rod 12 can be tightly locked together, thereby ensuring the stability of the nozzle part 2.

[0040] The inner side wall of the mounting ring 4 is provided with a fixing groove 41, and the locking assembly 6 includes an elastic fixing block 61 slidably connected in the fixing groove 41. A handle bar 62 is fixedly connected to a side of the fixing block 61 close to the bottom wall of the fixing groove 41, one end of the handle bar 62 penetrates the mounting ring 4 and is placed outside the mounting ring 4, and a protective cover 63 is sleeved and fixedly connected to the end of the handle bar 62 placed outside the mounting ring 4.

[0041] One end of the handle bar 62 located inside the fixing groove 41 is also sleeved with a locking spring 64, one end of the locking spring 64 is fixedly connected to the fixing block 61, and the other end is fixedly connected to the bottom wall of the fixing groove 41. The fixing block 61 is pressed against the bottom wall of the annular groove 121 by the force of the locking spring 64.

[0042] When the handle bar 62 is pulled away from the gun barrel 12, the locking spring 64 continues to be compressed, and the fixing block 61 also moves with the handle bar 62, thereby disengaging from the bottom wall of the annular groove 121. At this time, the handle bar 62 and the mounting ring 4 can be easily rotated to adjust the angle of the spray head 2. After the angle is adjusted, the handle bar 62 is released, and the locking spring 64 pushes the fixing block 61 to tightly press against the bottom wall of the annular groove 121, thereby locking the mounting ring 4 and the gun barrel 12 together.
