[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a mobile grouting device for construction engineering, including a mobile vehicle body 2, a grout storage tank 1 installed in the middle of the mobile vehicle body 2, the grout storage tank 1 storing grout, and a delivery pump installed on the top of the grout storage tank 1. A fixing plate 4 is welded to the mobile vehicle body 2, and a mounting base 7 is connected to the fixing plate 4 by screws. A column 24 is vertically welded to the mounting base 7. There are two columns 24, and a top plate 5 is welded to the upper end of the columns 24. A motor 3 is vertically installed on the top plate 5. The output shaft of the motor 3 drives a lead screw 16. The lower end of the lead screw 16 is rotatably connected to the mounting base 7. A threaded nut 18 is threaded onto the lead screw 16, and a fitting is fitted on the threaded nut 18. The floating seat 6 is screwed to a lifting plate 17. A connecting column 12 is horizontally welded to the outer wall of the lifting plate 17. The end of the connecting column 12 away from the lifting plate 17 is connected to a mounting plate 8. When the motor 3 is powered on, the output shaft of the motor 3 rotates, which in turn drives the lead screw 16 to rotate. When the lead screw 16 rotates, it will drive the lead screw sleeve 18 to move. When the lead screw sleeve 18 moves, it will drive the floating seat 6 to move up and down, so that the lifting plate 17 can move up and down. In addition, an ear block is fixed to the outer wall of the floating seat 6. The ear block has a sliding hole for the column 24 to pass through freely. In this way, when the floating seat 6 moves up and down, the column 24 slides in the sliding hole, so that the floating seat 6 can be guided.

[0033] A connecting pipe 9 is installed on the mounting plate 8. In addition, a clearance groove 20 is opened on the mounting plate 8 to allow the connecting pipe 9 to pass freely. The inner diameter of the clearance groove 20 is much larger than the outer diameter of the connecting pipe 9, so that the connecting pipe 9 is movably connected to the mounting plate 8. A grouting pipe 10 is installed at the lower end of the connecting pipe 9, and a connection port 19 is connected to the upper end of the connecting pipe 9. The connection port 19 is connected to the grout storage tank 1 through a pipeline. When the delivery pump is started, the grout in the grout storage tank 1 is delivered to the connection port 19, and then enters the connecting pipe 9 from the connection port 19. The grout then enters the grouting pipe 10 from the connecting pipe 9, and then flows from the grouting pipe 10 into the cracks or gaps in the foundation.

[0034] Furthermore, the lower end of the connecting pipe 9 is provided with a through hole for the grouting pipe 10 to pass through freely. The diameter of the through hole is smaller than the inner diameter of the connecting pipe 9. One end of the grouting pipe 10 that enters the connecting pipe 9 is coaxially fixed with an annular flange 21. The annular flange 21 slides freely inside the connecting pipe 9. The lower end of the grouting pipe 10 is fixedly fitted with a limiting ring 23. The lower end of the connecting pipe 9 is provided with an annular protrusion 22 that is turned outward. A spring 11 is provided between the annular protrusion 22 and the limiting ring 23. The spring 11 is wrapped around the grouting pipe 10. The two ends of the spring 11 in the direction of elastic force respectively elastically abut against the limiting ring 23 and the annular protrusion 22.

[0035] When the grouting pipe 10 moves downward, the spring 11 elastically abuts against the limiting ring 23, causing the lower end of the grouting pipe 10 to abut against the bottom wall of the crack and gap in the foundation. In addition, two fixing rings 14 are fixedly sleeved on the upper end of the connecting pipe 9. The opposite surfaces of the two fixing rings 14 abut against the upper and lower surfaces of the mounting plate 8, respectively. The outer diameter of the fixing ring 14 is larger than the inner diameter of the clearance groove 20. A fixing block 15 is fixedly connected to the mounting plate 8. A tension spring 13 is fixedly connected to the periphery of the fixing ring 14. The end of the tension spring 13 away from the fixing ring 14 is fixedly connected to the outer wall of the fixing block 15. Multiple tension springs 13 are arranged in an array along the axial direction of the clearance groove 20.

[0036] When the mobile vehicle 2 moves, the lower end of the grouting pipe 10 is inserted into the crack or gap. The grouting pipe 10 slides along the inner wall of the crack or gap. When sliding, since the crack or gap is not a straight line, the movement trajectory of the grouting pipe 10 is also curved. When the grouting pipe 10 moves, it drives the fixing ring 14 to move synchronously. Since the outer diameter of the fixing ring 14 is larger than the inner diameter of the clearance groove 20, the movement of the grouting pipe 10 on the mounting plate 8 will not be interfered with when the grouting pipe 10 moves in the crack or gap. That is, when the grouting pipe 10 moves in the crack or gap, it will correspondingly cause the tension spring 13 to be in a stretched or compressed state, thereby causing the tension spring 13 to accumulate elastic potential energy. In this way, through the elastic potential energy of the tension spring 13, the connecting pipe 9 and the grouting pipe 10 can move along the direction of the ground crack or gap.

[0037] The working principle of this utility model is as follows: A worker pushes the mobile vehicle 2 to move along the cracks and gaps in the foundation. The motor 3 is energized, and its output shaft rotates, driving the lead screw 16 to rotate. When the lead screw 16 rotates, it moves the lead screw sleeve 18, which in turn moves the floating seat 6 up and down, thus moving the lifting plate 17 up and down. When the floating seat 6 moves downwards, the grouting pipe 10 is inserted into the cracks and gaps in the foundation. The spring 11 elastically abuts against the limiting ring 23, causing the lower end of the grouting pipe 10 to abut against the bottom wall of the cracks and gaps in the foundation. As the mobile vehicle 2 moves, the lower end of the grouting pipe 10 is inserted into the cracks or gaps. Within the gap, the grouting pipe 10 slides along the inner wall of the crack or void. During the sliding, since the crack or void is not a straight line, the movement trajectory of the grouting pipe 10 is also curved. When the grouting pipe 10 moves, it synchronously drives the fixing ring 14 to move. Since the outer diameter of the fixing ring 14 is larger than the inner diameter of the clearance groove 20, the movement of the grouting pipe 10 on the mounting plate 8 will not be interfered with when the grouting pipe 10 moves within the crack or void. That is, when the grouting pipe 10 moves within the crack or void, it will correspondingly cause the tension spring 13 to be in a stretched or compressed state, thereby causing the tension spring 13 to accumulate elastic potential energy. In this way, through the elastic potential energy of the tension spring 13, the connecting pipe 9 and the grouting pipe 10 can move along the direction of the ground crack or void.
