Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a grouting device for expansion joints in road construction. Background Technology

[0002] Expansion joint grouting is a construction technique used in building engineering to fill and seal structural expansion joints. It aims to ensure that buildings can expand and contract freely under the influence of factors such as temperature changes and settlement without cracking or leakage. Expansion joints are gaps designed to accommodate the deformation of buildings caused by temperature changes, humidity changes, and loads.

[0003] However, in the existing technology, traditional expansion joint grouting devices use a dust suction mechanism to clean the dust and impurities inside the expansion joint. Some clumps of dust and impurities are not easy to suck out, which affects the curing effect of the grouting material and reduces the grouting effect of the expansion joint. Moreover, the grouting head is not easy to adjust according to the depth of the expansion joint, which makes it easy for the grouting material to scatter around the expansion joint, which not only affects the aesthetics, but also makes cleaning time-consuming and laborious. Utility Model Content

In addition, the grouting head is not easy to adjust according to the depth of the expansion joint, and the grouting material is easy to scatter around the expansion joint, which not only affects the aesthetics but also makes cleaning time-consuming and laborious.

[0036] In this embodiment, the vehicle body 1 is moved to the expansion joint, so that the cleaning brush 113 is embedded inside the expansion joint. The drive motor 109 is turned on and drives multiple connecting plates 111 to rotate through the connecting shaft 110. One end of the multiple connecting plates 111 is fixedly installed with the cleaning brush 113, and the other end is fixedly installed with the cleaning hook 112. The cleaning hook 112 can clean out the hard-to-clean impurities that have clumped inside the expansion joint. Then, the cleaning brush 113 sweeps out the impurities and dust, improving the cleanliness inside the expansion joint. The multiple cleaning brushes 113 and cleaning hooks 112 clean alternately, which can better improve the cleaning effect. While the vehicle body 1 is moving, the rolling roller 118 can be driven to roll the expansion joint, so that the grouting material is level with the road surface, improving the flatness of the expansion joint.

[0037] Example 2, as Figure 1-4 As shown, a pump body 104 is fixedly installed on the top of the vehicle body 1. A telescopic pipe 115 is fixedly installed at the output end of the pump body 104, and the telescopic pipe 115 penetrates the vehicle body 1.

One end of each connecting plate 111 is fixedly equipped with a cleaning brush 113, and the other end is fixedly equipped with a cleaning hook 112. The cleaning hook 112 can remove hard-to-clean debris from inside the expansion joint, and then the cleaning brush 113 sweeps away the debris and dust, improving the cleanliness of the expansion joint. The multiple cleaning brushes 113 and cleaning hooks 112 alternate in cleaning, further enhancing the cleaning effect. The pump body 104 is turned on to deliver the grouting material inside the inclined tank 102 to the inside of the expansion pipe 115, and then injects it into the expansion joint through the grouting head 116. The electric push rod 106 can drive the telescopic tube 115 to extend and retract via the adjusting plate 114, adjusting according to the depth of the expansion joint, so that the grouting head 116 can be better embedded, preventing the grouting material from scattering around. While pushing the vehicle body 1 to move, it can drive the rolling roller 118 to roll the expansion joint, making the grouting material level with the road surface and improving the flatness of the expansion joint. The mixing motor 103 drives multiple mixing blades 120 via the mixing rod 119 to mix the grouting material inside the inclined tank 102, preventing sedimentation and uneven mixing, which would affect the grouting effect. The U-shaped scraper 121 can clean the grouting material adhering to the inner wall, preventing it from affecting the mixing degree of the grouting material. The inclined tank 102 can facilitate the outflow of the grouting material inside, improving the grouting effect.
