Description

Technical Field

[0001] The utility model relates to the technical field of grouting construction equipment, in particular to a grouting device. Background Art

[0002] Tunnels are engineering structures buried in the ground and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels and mining tunnels. During the construction of tunnels, since the soil around the tunnels is relatively loose and prone to collapse, cement mortar is injected between the tunnel construction template and the soil layer to fill the gap between the tunnel template and the soil layer.

[0003] A Chinese patent discloses a tunnel construction grouting device (authorization announcement number CN219344709U), which drives a rotating rod to rotate through a motor, thereby rotating a stirring rod to stir the material in the storage tank to prevent the material from solidifying; however, when the motor drives the rotating rod and the stirring rod to rotate, the material in the storage tank is prone to vortex phenomenon as the rotating rod and the stirring rod rotate. Since the direction of the vortex is the same as the stirring direction of the stirring rod, this means that part of the material cannot be stirred, resulting in uneven stirring of the material. Moreover, after stirring, more material will adhere to the inner wall of the storage tank, resulting in waste and increasing the cost of use. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0021] like Figure 1-Figure 3 As shown, a grouting device comprises a base 1, a stirring structure 2 and a grouting head 3;

[0022] A base 1, with a roller 11 at the bottom;

[0023] The stirring structure 2 includes a stirring barrel 21, a first motor 22, a transverse connecting rod 23, a fixed rod 24, a stirring rod 25, a feeding port 26 and a discharging port 27; the stirring barrel 21 is hollow and is arranged on the base 1; the first motor 22 is arranged above the stirring barrel 21, and the output shaft extends downward into the stirring barrel 21 and is connected to the transverse connecting rod 23; the stirring rod 25 is vertically arranged at the right end of the transverse connecting rod 23, and a plurality of fan blades 28 are arranged on the stirring rod 25; the fixed rod 24 is vertically arranged in the stirring barrel 21, and the lower part is connected to the bottom of the stirring barrel 21, and a plurality of baffles 29 are arranged on the fixed rod 24, and the baffles 29 and the fan blades 28 are staggered; the feeding port 26 is arranged at the upper part of the stirring barrel 21, and the discharging port 27 is arranged at the lower part of the stirring barrel 21;

[0024] The grouting head 3 is connected to the discharge port 27 via a grouting pipe 31 .

[0025] When using the device, first, the entire device is driven to move to the construction area by the roller 11; the material is put into the mixing barrel 21 from the feeding port 26, and the first motor 22 is started. The first motor 22 drives the transverse connecting rod 23 to rotate, and the transverse connecting rod 23 drives the stirring rod 25 to make a circular motion around the fixed rod 24. The blades 28 on the stirring rod 25 stir the material in the mixing barrel 21. The blades 28 and the baffles 29 are staggered, and no collision occurs when the blades 28 move. The baffles 29 can prevent the material from forming a vortex, thereby improving the stirring effect. After the stirring is completed, the material is transported to the grouting head 3 for grouting through the slurry pipe 31.

[0026] like Figure 2 As shown, as a preferred embodiment, the stirring structure 2 further includes a first gear 210 and a second gear 211; the upper portion of the stirring rod 25 is rotatably connected to the right end portion of the transverse connecting rod 23, and the first gear 210 is sleeved on the stirring rod 25; the second gear 211 is arranged on the top of the fixing rod 24, and the second gear 211 is meshed with the first gear 210. In this embodiment, the stirring rod 25 is arranged to be rotatable, and when the first motor 22 drives the transverse connecting rod 23 to rotate, due to the meshing of the first gear 210 and the second gear 211, the first gear 210 rotates along the second gear 211 to drive the stirring rod 25 to rotate, thereby enhancing the stirring effect, and the second gear 211 can limit the motion trajectory of the first gear 210, so that the entire motion process is more stable.

[0027] like Figure 2 As shown, as a preferred embodiment, it also includes a cleaning plate 4, which is vertically arranged close to the inner wall of the mixing barrel 21 and connected to the left end of the transverse connecting rod 23 through a cross bar 41. In this embodiment, the cleaning plate 4 is connected to the transverse connecting rod 23 through the cross bar 41. When the first motor 22 drives the transverse connecting rod 23 to rotate, the cleaning plate 4 rotates along the inner wall of the mixing barrel 21 to scrape off the material attached to the inner wall, thereby reducing the waste of materials.

[0028] like Figure 3 As shown, as a preferred embodiment, it also includes a grouting height adjustment structure 5, including a support frame 51, a second motor 52, a first winding drum 53 and a grouting mounting plate 54; the support frame 51 is arranged on the base 1, and the grouting mounting plate 54 is slidably arranged between the vertical poles of the support frame 51, and a grouting hole 55 is provided in the middle of the grouting mounting plate 54, and the grouting head 3 is fixed through the grouting hole 55; the second motor 52 is arranged on the side wall of the vertical pole of the support frame 51, and the output shaft passes through the vertical pole and is connected to the cross bar of the support frame 51 to drive the cross bar to rotate; the first winding drum 53 is arranged on the cross bar of the support frame 51, and the wire rope on the first winding drum 53 is connected to the grouting mounting plate 54. In this embodiment, it is necessary to adjust the height of the grouting head 3, and the second motor 52 is started. The second motor 52 drives the cross bar of the support frame 51 to rotate. At this time, the first winding drum 53 follows the rotation to pull the wire rope and pull the grouting mounting plate 54 upward to realize the rising of the grouting head 3. When it needs to be lowered, it can be rotated in the opposite direction. The first winding drum 53 releases the wire rope, and the grouting mounting plate 54 drops due to its own weight, thereby realizing the lowering adjustment of the grouting head 3.

[0029] like Figure 3As shown, as a preferred embodiment, the grouting height adjustment structure 5 also includes a second winding drum 56, which is arranged on the crossbar of the support frame 51, and the wire rope is connected to the grouting installation plate 54. In this embodiment, the second winding drum 56 is arranged to work together with the first winding drum 53 to improve the stability of the device.

[0030] like Figure 1 As shown, as a preferred embodiment, a delivery pump 32 is further provided on the grouting pipe 31. In this embodiment, when the grouting head 3 rises to a certain height, the delivery pump 32 is used to deliver the material so that the material can enter the grouting head 3 better.

[0031] like Figure 1 As shown, as a preferred embodiment, a handrail 6 is provided at the end of the base 1. In this embodiment, the handrail 6 is provided on the base 1, and the operator uses the handrail 6 to better push the device to move.
