Description

Technical Field

[0001] The utility model relates to the technical field of wetting trolley equipment, and particularly to a rotary spraying mechanism of an engineering concrete wetting trolley. Background Technique

[0002] A concrete wetting trolley is usually used for wet spraying operations during concrete construction. The concrete wetting trolley pumps water from a water tank through a pumping system and then evenly sprays it onto the concrete surface under construction through a wetting device, which helps to control the water-cement ratio of the concrete and improve the quality and durability of the concrete.

[0003] When the existing engineering concrete wetting trolley is in use, the spraying end of its rotary spraying mechanism is at a position close to the rock wall at a small distance. If the operator makes a technical mistake during the construction of the wetting trolley, it is easy to cause the rotary spraying mechanism to collide with the surface of the rock wall. And the spraying end of the existing rotary spraying mechanism is often exposed outside, with poor protection effect, and it is very easy to cause damage to the rotary spraying mechanism.

[0004] Therefore, a rotary spraying mechanism of an engineering concrete wetting trolley is proposed. Content of the Utility Model

[0024] Such as Figures 1 to 4As shown in the figure, the rotary spraying mechanism of the engineering concrete wetting trolley includes a frame assembly 1. A connecting pipe 2 is arranged inside the frame assembly 1, and the free end of the connecting pipe 2 is connected to a nozzle body 3. A collar 4 is arranged on the end face of the frame assembly 1 and on the surface of the nozzle body 3. A rubber anti-slip pad 5 is embedded in the inner wall of the collar 4. An axial buffer mechanism 6 is arranged on the surface of the collar 4, and a movable sleeve 7 is fixedly installed at the movable end of the axial buffer mechanism 6. The movable sleeve 7 and the collar 4 are movably sleeved. A universal buffer mechanism 8 is arranged on the surface of the movable sleeve 7, and an anti-collision shell 9 is arranged on the movable sleeve 7 through the universal buffer mechanism 8. The axial buffer mechanism 6 is used to buffer the axial impact force, and the universal buffer mechanism 8 is used to buffer the impact force. Specifically, the connecting pipe 2 is protected by the frame assembly 1, so as to prevent the connecting pipe 2 from being damaged due to impact during construction. The collar 4 and the movable sleeve 7 are located outside the nozzle body 3, so as to protect the nozzle body 3 through the collar 4 and the movable sleeve 7. When being impacted, the anti-collision shell 9 drives the movable sleeve 7 to displace, and the impact force received by the anti-collision shell 9 is buffered and absorbed through the axial buffer mechanism 6 and the universal buffer mechanism 8, so as to prevent the nozzle body 3 from being damaged due to the impact force.

[0025] As Figure 1 , Figure 2 , Figure 3 shown in the figure, the frame assembly 1 includes a frame body 101. A receiving cavity 102 is opened on the bottom surface of the frame body 101. The connecting pipe 2 is placed inside the receiving cavity 102, and a bearing ring 103 is fixedly installed on the surface of the receiving cavity 102. Specifically, the connecting pipe 2 is received through the receiving cavity 102 in the frame body 101, and the connecting pipe 2 is fixed through the bearing ring 103, so that the connecting pipe 2 is located inside the frame body 101, and thus the connecting pipe 2 is protected.

[0026] As Figure 1 , Figure 2 , Figure 3 shown in the figure, the axial buffer mechanism 6 includes a buffer damper 601. The buffer damper 601 is fixedly installed on the left inner wall of the collar 4, and the free end of the buffer damper 601 and the left side wall of the movable sleeve 7 are fixedly installed. A first spring 602 is sleeved on the surface of the buffer damper 601. Rubber protective sleeves 603 are fixedly installed on the surface of the collar 4 and the left side wall of the movable sleeve 7. Multiple groups of buffer dampers 601 and first springs 602 are all located inside the buffer damper 601. Specifically, the impact force drives the anti-collision shell 9 to make the movable sleeve 7 move along the surface of the collar 4, so as to compress the buffer damper 601 and the first spring 602. The axial impact force is buffered through the buffer damper 601 and the first spring 602, and the buffer damper 601 and the first spring 602 are protected through the rubber protective sleeve 603.

[0027] As shown Figure 3 , Figure 4 in, the universal buffer mechanism 8 includes a rubber ring 801. The right side wall of the movable sleeve 7 is fixedly installed with the rubber ring 801. (As shown Figure 4 ) and the rubber ring 801 is hollow. The movable sleeve 7 is connected to the anti-collision shell 9 through the rubber ring 801. A second spring 802 is arranged on the surface of the movable sleeve 7, and the free end of the second spring 802 is fixedly installed on the inner wall of the anti-collision shell 9. Specifically, the impact force drives the anti-collision shell 9 to compress the hollow rubber ring 801 and stretch the second spring 802. The rubber ring 801 and the second spring 802 buffer and absorb the impact force.

[0028] As shown Figure 1 , Figure 3 , Figure 4 in, the nozzle body 3 is located inside the collar 4 and the movable sleeve 7. And in the normal state, the spraying end of the nozzle body 3 is located inside the movable sleeve 7. Specifically, since the nozzle body 3 is located inside the collar 4 and the movable sleeve 7, the collar 4 and the movable sleeve 7 protect the nozzle body 3.

[0029] As shown Figure 3 in, an annular groove is formed on the inner wall of the collar 4, and a rubber anti-slip pad 5 is embedded in the annular groove on the inner wall of the collar 4, and anti-slip patterns are formed on the surface of the rubber anti-slip pad 5. Specifically, the rubber anti-slip pad 5 embedded on the inner wall of the collar 4 facilitates the fixation of the nozzle body 3.

[0030] In summary: The frame assembly 1 protects the connecting pipe 2, preventing the connecting pipe 2 from being damaged due to impact during construction. Since the collar 4 and the movable sleeve 7 are located outside the nozzle body 3, the collar 4 and the movable sleeve 7 protect the nozzle body 3. When being impacted, the anti-collision shell 9 drives the movable sleeve 7 to displace. The axial buffer mechanism 6 and the universal buffer mechanism 8 buffer and absorb the impact force received by the anti-collision shell 9, thereby preventing the nozzle body 3 from being damaged due to the impact force.
