Description

Technical Field

[0001] This utility model relates to the field of grouting technology in building engineering, specifically to a gap grouting device for building engineering. Background Technology

[0002] Grouting refers to the process of pumping grout into the cracks, fault fracture zones, or joints and fissures of the foundation of hydraulic structures. In the construction industry, it is usually necessary to grout the gaps or cracks of buildings to enhance the overall stability of the buildings and prevent them from being damaged later. There are many structural gaps in building engineering, and they are located at different heights, but all of them need to be filled with sufficient grout.

[0003] In the prior art, Chinese utility model application number CN202321554108.6 discloses a grouting device for construction engineering, including a pressure pump, a pressure pipe connected to the discharge end of the pressure pump, a mortar funnel installed at the top of the outer side of the pressure pipe, a slurry outlet pipe connected to the discharge end of the pressure pipe, a collar sleeved on the outer side of the slurry outlet pipe, a bracket installed at one end of the collar, a rotating block rotatably installed on one side of the bracket, a scraper installed on one side of the rotating block, and a return plate installed on one side of the scraper. While moving, the device continuously injects mortar into the gap. At this time, under the action of the support wheel, the scraper will scrape the overflowing mortar on one side of the scraper and then move together. When encountering a position where the mortar is insufficiently filled, the mortar will be pushed back to the gap by the return plate to refill it. This ensures that all mortar can be fully utilized during the gap filling process, and secondary filling can be carried out without manual intervention. This increases the aesthetics of the gap filling while reducing the need for manual labor.

[0004] While the above-mentioned technical solutions facilitate the smoothing of mortar at the crack opening after grouting, the mortar in the mortar funnel may settle or solidify if left to stand for a long time, thereby reducing the mortar delivery efficiency and potentially causing mortar lumps to block the grout outlet pipe. At the same time, the scraper may wobble due to its light weight, resulting in mortar overflow and affecting the appearance of the crack repair. Therefore, we need to propose a crack grouting device for building engineering. Summary of the Invention

[0005] The purpose of this utility model is to provide a grouting device for building engineering, which facilitates the stirring of grouting mortar in the mortar funnel, avoids sedimentation, stratification or solidification of mortar before it is fully used, thereby improving the efficiency of grouting building gaps and ensuring that the mortar smoothly fills the gaps. At the same time, it increases the counterweight of the scraper, so that the bottom of the scraper can fit in close contact with the building surface, improving the smoothing quality after gap repair, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grouting device for construction engineering, comprising a trolley, on which two sets of bases are fixedly connected, each with a pressure pump and a pressure pipe respectively.

[0007] The anti-solidification mechanism includes a rotating shaft rotatably disposed inside the mortar funnel. One end of the rotating shaft passes through the mortar funnel and is driven by a motor. Three sets of wall-scraping and stirring components are disposed on the outer side of the rotating shaft.

[0008] Preferably, the wall-scraping agitator includes multiple sets of agitating rods and wall-scraping rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model mainly utilizes the cooperation between a mortar funnel, an anti-solidification mechanism, an auxiliary support mechanism, and a weighted scraper. A motor-driven rotating shaft rotates multiple sets of wall-scraping agitators to mix the mortar within the funnel, improving the uniformity of the mortar mixture while ensuring its fluidity. This prevents sedimentation and stratification, and avoids solidification. Simultaneously, the wall-scraping agitators scrape away mortar from the inner wall of the funnel, improving cleaning efficiency. Furthermore, the weighted scraper enhances the stability of scraping mortar from overflowing gaps, thus improving the appearance of the repaired mortar. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a grouting device for construction engineering, including a trolley 1, on which two sets of bases 2 are fixedly connected, and respectively equipped with a pressure pump 3 and a pressure pipe 4. A mortar funnel 5 is provided above the pressure pipe 4, and an anti-solidification mechanism 6 for stirring the mortar is provided inside the mortar funnel 5. A detachable grout outlet pipe 7 is provided at the discharge end of the pressure pipe 4, and an auxiliary support mechanism 8 is provided at the discharge end of the grout outlet pipe 7. A weighted scraper 9 for leveling the mortar is detachably provided on the auxiliary support mechanism 8.

[0022] The anti-solidification mechanism 6 includes a rotating shaft 62 rotatably disposed inside the mortar funnel 5. One end of the rotating shaft 62 passes through the mortar funnel 5 and is driven by a motor 61. Three sets of wall scraping and stirring components 63 are disposed on the outer side of the rotating shaft 62.

[0023] The wall-scraping agitator 63 includes multiple sets of agitating rods 631 and wall-scraping rods 632. One end of each agitating rod 631 is fixedly connected to the outside of the rotating shaft 62, and the other end of each agitating rod 631 is fixedly connected to one side of the wall-scraping rod 632. The other side of the wall-scraping rod 632 abuts against the inner wall of the mortar funnel 5. The multiple agitating rods 631 facilitate rapid mixing of the mortar, thereby improving the uniformity of the mortar mixing and preventing the mortar from settling or solidifying. In addition, the wall-scraping rods 632 can prevent the mortar from adhering to the bottom of the mortar funnel 5, making it convenient to clean the equipment after grouting.

[0024] The weighted scraper 9 includes a scraper 91. Two sets of baffles 92 are fixedly connected to one side of the scraper 91. A counterweight hopper 93 is fixedly connected to one end of the upper surface of the two sets of baffles 92. The counterweight hopper 93 is located above the discharge end of the slurry pipe 7. A corrugated pipe 71 is provided in the middle of the slurry pipe 7. A counterweight is added to the counterweight hopper 93 to increase the pressure on the ground, so that the scraper 91 can better fit with the ground, thereby improving the quality of the scraper 91 in leveling the mortar and improving the appearance of the repaired surface after grouting.

[0025] Two sets of second hinge seats 94 are fixedly connected to one side of the scraper 91. A second hanging rod 95 is rotatably installed on each set of second hinge seats 94. The scraper 91 is V-shaped. The shape of the scraper 91 makes it easy to gather the mortar overflowing from the gap, so that the mortar rolls repeatedly between the scraper 91 and the baffle 92, so as to better grout the gap and improve the grouting effect.

[0026] The auxiliary support mechanism 8 includes a sleeve 81 for installing the slurry pipe 7. Two sets of connecting shafts 82 are fixedly connected to the outside of the sleeve 81. Rollers 83 are rotatably provided at opposite ends of the two sets of connecting shafts 82. Multiple sets of limiting rings 84 are provided on the outside of the two sets of connecting shafts 82. The sleeve 81 facilitates the installation of the discharge end of the slurry pipe 7, thereby improving the stability of the slurry pipe 7. The multiple sets of limiting rings 84 facilitate the limiting of the first hanging rod 85 and the second hanging rod 95, thereby improving the overall stability of the equipment.

[0027] Both sets of connecting shafts 82 have a first hanging rod 85 snapped onto their outer sides. One end of the first hanging rod 85 is rotatably connected to a first hinge seat 86, which is fixedly connected to one side of the trolley 1. The second hanging rod 95 is snapped between two sets of limiting rings 84. A slot is provided between two adjacent sets of limiting rings 84 for the first hanging rod 85 and the second hanging rod 95 to snap onto each other. The first scraper facilitates the limiting of the connecting shaft 82 of the auxiliary support mechanism 8, thereby facilitating the synchronous movement of the trolley 1 and the auxiliary support mechanism 8, and improving the stability of the positioning of the slurry pipe 7. The hanging ends of the first hanging rod 85 and the second hanging rod 95 are both C-shaped, which facilitates quick snapping onto the connecting shaft 82. The limiting rings 84 limit the position of the first hanging rod 85 and the second hanging rod 95, preventing them from shifting.

[0028] The bottom of the mortar funnel 5 is set in a semi-cylindrical shape. Both sides of the mortar funnel 5 are fixedly connected to the columns 51 installed on the trolley 1. The lower end of the mortar funnel 5 is provided with a connecting pipe 52 that is connected to the pressure pipe 4. The shape of the mortar funnel 5 makes it convenient for the scraper rod 632 to scrape the mortar on the inner wall of the mortar funnel 5, thereby improving the cleaning efficiency.

[0029] In use, the grouting mortar is placed in the mortar funnel 5. The motor 61 drives the rotating shaft 62 to drive the three sets of scraper agitators 63 to mix the mortar, improving the uniformity of the mortar mixture while ensuring its fluidity and preventing sedimentation or solidification. The mortar is then pumped through the pressurization pipe 4 into the grout outlet pipe 7 by the pressure pump 3, allowing the mortar to fall into the gap that needs grouting. By pushing the trolley 1, the auxiliary support mechanism 8 moves the grout outlet pipe 7 and the weighted scraper 9 synchronously, thereby improving the grouting efficiency of the building gaps. At the same time, by adding counterweights (stones or iron blocks) in the weighted hopper, the pressure of the scraper 91 on the building floor is increased, allowing the scraper 91 to better adhere to the ground, so that the mortar overflowing from the gap can be evenly scraped, thereby improving the appearance of the repair after grouting and increasing the efficiency of the repair.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
