Description

Technical Field

[0001] The present invention relates to the technical field of crack grouting, and more specifically, to a structural crack grouting device. Background Art

[0002] During the construction of building projects, cracks may occur at some structural joints, and it is necessary to grout the cracks to enhance the overall stability of the building and avoid later damage to the building. During the grouting process, grouting equipment is required to inject concrete slurry into the cracks.

[0003] After retrieval, according to the patent network CN119122287A, it relates to a structural crack grouting device for building projects, including a vehicle body and a handle provided on the upper side wall of the vehicle body. A control button is fixedly connected to the side wall of the handle, and a PLC controller is fixedly connected to the lower side wall of the vehicle body. The control button and the PLC controller are electrically connected. When using this grouting device to grout the cracks in the structure of a building project, it can automatically insert an appropriate amount of injection pipes into the cracks for grouting treatment according to the width of the cracks. By simultaneously grouting with multiple injection pipes, the conveying efficiency of the grouting device is greatly improved. And after using the grouting device to fill the cracks with slurry, it can timely control the grouting device to stop working, thus avoiding the problem that if the operator manually closes the grouting device, the slurry will overflow from the cracks, resulting in waste of slurry.

[0004] However, when the existing crack grouting device is in use, although it can perform better grouting operations on the cracks through the grouting nozzle, when grouting the cracks in the horizontal direction of the road surface, the surface scraping effect after crack grouting is not high, and the clamping and disassembly effect of the leveling scraper is not high. At the same time, when switching between grouting the horizontal cracks and the vertical cracks of the structure, the slurry recovery effect during vertical crack grouting is not high, and it is easy to cause dripping of the slurry during vertical crack grouting, resulting in waste of the slurry, which does not meet the usage requirements of people.

[0047] Furthermore, the leveling scraper 707 forms a detachable structure with the lifting rod 705 through the first bolt 709 and the card slot 710. It is conducive to the first bolt 709 sliding along the inner wall of the card slot 710, driving the leveling scraper 707 and the lifting rod 705 to be snap-connected, achieving the effect of convenient disassembly, installation and replacement of the leveling scraper 707, and meeting the need for adjusting and leveling after grouting the transverse gaps on different road surfaces.

By providing the lifting mechanism 8 and the flipping mechanism 9, when it is necessary to perform grouting operations on gaps in different vertical and horizontal directions through the grouting device, in order to improve the convenient switching effect of the working position of the grouting nozzle 13, the driving of the lifting mechanism 8 can be used to drive the connecting seat 12 to rise from the connecting groove 6, and through the driving of the flipping mechanism 9, the connecting seat 12 can be driven to rotate along the outer wall of the lifting block 803 under the rotation of the swing rod 905, so that the grouting nozzles 13 are arranged vertically, achieving the effect of switching grouting for vertical and horizontal multi-directional gaps.

[0051] Further, the threaded slider 903 and the limiting groove 904 constitute a sliding structure through the threaded rod 902. An engaging groove is provided at the connecting portion between the outer wall of the swing rod 905 and the threaded slider 903. The rotation center of the swing rod 905 is fixedly connected to the rotation center of the connecting seat 12 through a rotating shaft, which is beneficial to the rotation of the threaded rod 902 to drive the threaded slider 903 to slide along the inner wall of the limiting groove 904, playing a role in conveniently adjusting the using direction of the connecting seat 12, and is beneficial to fixedly connecting the rotation center of the swing rod 905 to the rotation center of the connecting seat 12 through a rotating shaft, achieving the effect of improving the smoothness of the direction rotation of the connecting seat 12.

[0052] Further, the material receiving mechanism 10 includes a rotating rod 1002 and a material receiving box 1006.

An installation groove 1005 is provided at the connecting portion between the outer wall of the rotating rod 1002 and the second bolt 1004. By providing the material receiving box 1006, when performing grouting operations on vertical gaps through the grouting nozzle 13, in order to improve the material receiving and recycling effect of the slurry during use, the second servo motor 1001 can be turned on to drive the material receiving box 1006 that is snap-connected to the rotating rod 1002 to perform a synchronous flipping movement through the flipping movement of the rotating rod 1002, playing a role in reducing the use cost of the slurry.

[0053] Further, the outer wall contour of the material receiving box 1006 is U-shaped.

[0054] Such as Figure 1 shown, when using this structural joint grouting device, first, when grouting the building structure joint through the grouting device, in order to improve the flatness of the surface of the road joint after grouting and prevent the slurry from being too much or too little, resulting in protrusions and depressions, after grouting the road joint through the grouting nozzle 13, the second electric push rod 701 can be opened to drive the sliding rod 702 to slide along the inner wall of the fixed groove 703, and the third electric push rod 704 can be opened.

[0056] Next, when it is necessary to grout joints in different vertical and horizontal directions through the grouting device, in order to improve the convenient switching effect of the working position of the grouting nozzle 13, the driving of the lifting mechanism 8 can be used to drive the connecting seat 12 to rise from the connecting groove 6, and through the driving of the flipping mechanism 9, the connecting seat 12 is driven to perform a flipping movement along the outer wall of the lifting block 803 under the rotation of the swinging rod 905, so that the grouting nozzle 13 is in a vertically arranged state, achieving the effect of switching grouting for vertical and horizontal multi-directional joints;
