Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a grouting device for building construction. BACKGROUND

[0002] Grouting refers to the process of pressing slurry into the cracks, fault fracture zones of the building foundation or the joints and cracks of the building itself. In the field of building construction, it is often necessary to grout the gaps or cracks of the building to enhance the overall stability of the building and prevent the building from being damaged later. Grouting can improve the foundation conditions and the stress characteristics of the building, and improve the impermeability and bearing capacity of the foundation or the impermeability, integrity and safety of the building. When grouting the structural joints or foundation, grouting equipment is usually used.

[0003] The current handheld grouting machine can fill the building structure joints or cracks well and conveniently, but when grouting the cracks or structure joints on the inclined structure surface or horizontal plane, since the storage hopper of most handheld grouting machines is directly fixed on the machine body without a cover structure, the cement mortar or concrete mortar in the storage hopper will leak, which not only wastes materials, but also requires manual cleaning, which is time-consuming and labor-intensive.

[0004] In the prior art, for example, a building structure gap grouting device and a grouting method thereof are proposed in Chinese Patent No. 202211222178.1. By providing a side leakage prevention mechanism on the storage hopper, the grouting machine can close the cover plate on the storage hopper by pulling the clamping block when filling the ground gap, and the plate body can drive the clamping block to insert into the empty groove to position the cover plate under the action of the spring, so that the cover plate can ensure the sealing of the storage hopper when it is inclined. Although the above technical solution makes the cement mortar in the storage hopper not leak when the grouting machine fills the ground gap, thereby making the grouting machine more convenient when grouting the ground gap, the above grouting device needs to be opened regularly after the mortar in the storage hopper is used up, then the storage hopper is filled with mortar, and the cover plate is closed after the filling is completed. The filling process is relatively cumbersome. SUMMARY

[0022] The present application has the following beneficial effects:

[0023] 1. When grouting is needed on the inclined structure surface or the horizontal surface, the staff rotates the knob, the knob drives the rotating shaft and the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the discharge pipe and the feeding pipe to rotate, the feeding pipe drives the storage hopper to rotate, when the driven gear rotates, the protrusion one on the driven gear is out of the first adjusting groove, at the same time, the driven gear slides along its axis to the feeding pipe, the compression spring one is compressed, similarly, the protrusion two on the stabilizing wheel is also out of the first adjusting groove, at the same time, the stabilizing wheel slides along its axis to the corresponding side of the feeding pipe, the compression spring two is compressed, when the protrusion one and the protrusion two rotate into the next adjusting groove, the compression spring one and the compression spring two recover, at the same time, the driven gear one and the stabilizing wheel respectively extrude the left and right side surfaces of the guide grout seat, thus the angle adjustment between the orientation of the storage hopper injection port and the structure axis of the grouting pipe is completed, the orientation of the storage hopper injection port can keep upward in the case of the inclined structure surface or the horizontal surface, thus the cement mortar or concrete in the storage hopper can be prevented from spilling when the grouting device grouts the cracks or the structure connecting joints on the inclined structure surface or the horizontal surface, the feeding into the storage hopper is facilitated, the feeding time is saved, and the grouting efficiency is improved.

[0024] 2. When the caliber of the grouting head is adjusted, the staff rotates the adjusting hand wheel, the adjusting hand wheel drives the guide rod to rotate, the guide rod is limited by the mutually perpendicular guide groove one and guide hole, the guide rod moves along the length direction of the guide hole, at the same time, the guide rod is guided by the variable-diameter guide groove, the variable-diameter block is subjected to the force F1 perpendicular to the tangent direction of the adjusting disc and outward and the force F2 parallel to the tangent direction of the adjusting disc, the sliding block one and the sliding groove one cooperate to limit the freedom degree of the variable-diameter block along the tangent direction of the adjusting disc, therefore, the variable-diameter block moves outward along the direction perpendicular to the tangent direction of the adjusting disc, and the variable-diameter of the grouting head is achieved.

[0025] 3. The grout guide connection sealing plate can seal the gap between two adjacent variable diameter blocks, preventing cement mortar or concrete grout from flowing out along the gap, and further connect the two adjacent variable diameter blocks to improve the integrity of the grout outlet.

[0026] 4. When two adjacent reducing blocks move in a direction perpendicular to the tangent of the adjusting disc, sealing plate one and sealing plate two are respectively subjected to a tensile force F3 from the corresponding two reducing blocks, perpendicular to the tangent of the adjusting disc. This tensile force F3 is further decomposed into a force F4 perpendicular to the surfaces of sealing plate one and sealing plate two, and a force F5 along the relative sliding direction between the guide plate and the reducing block. Therefore, when two adjacent reducing blocks move in a direction perpendicular to the tangent of the adjusting disc, sealing plate one and sealing plate two will slide in opposite directions. Sealing plate one and sealing plate two are subjected to the tension of the return spring, causing sealing plate one and sealing plate two to separate and then re-enter. By combining them in a timely manner, during the process of expanding the grout outlet diameter, sealing plates one and two can maintain their continuity and stability without restricting the movement of the variable diameter blocks, thus ensuring the continuity and stability of multiple variable diameter blocks. When it is necessary to reduce the diameter of the grout outlet, simply turn the adjusting handwheel in the opposite direction, and multiple variable diameter blocks will return to their positions. At the same time, the grout guiding connecting sealing plate will also return to its position under the pressure of the variable diameter blocks. In this way, the grouting device can also adjust the diameter of the grout outlet according to the joint width. Therefore, the grouting device also has the advantage of strong adaptability, thereby improving work efficiency. Attached Figure Description
