Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a building engineering repair and caulking device. Background Technology

[0002] With the rapid development of the construction industry and the dramatic increase in the number of buildings, building repair and sealing equipment has gradually gained attention. It is mainly used for waterproofing and leak repair projects in buildings, including residential, commercial buildings and public facilities. It is particularly efficient and precise in dealing with minor cracks and leaks.

[0003] A Chinese patent with publication number 202122342465.3 discloses a building repair and crack filling device, including a carrier plate. A storage box is fixedly installed on the rear side of the upper surface of the carrier plate, and a liquid pump is fixedly installed in the middle of the upper surface of the carrier plate, with the liquid pump connected to the storage box. A hose is connected to the front side of the liquid pump, and an opening is opened on the front side of the carrier plate near the liquid pump, through which the hose passes. A nozzle is connected to the bottom of the hose, and a steel plate is fixedly installed on the outer side of the bottom of the nozzle. This utility model, by setting up a push rod motor a and a steel plate, allows the carrier plate to move downward through the drive shaft of the push rod motor a when repairing short cracks. The carrier plate can then move the steel plate downward, pressing the sealing gasket onto the road surface and sealing the crack. Subsequently, the material is pumped into the crack through the liquid pump and hose, filling it in one go, effectively avoiding the drawbacks caused by adding too much or too little liquid.

[0004] The above-mentioned patent still has the following shortcomings: the inner wall of the material tank is not easy to clean. Because mortar and sealant have strong adhesion, after being poured into the device, mortar, sealant and other materials will remain and accumulate on the inner wall of the tank. At the same time, the cleaning work requires more time and labor costs. Utility Model Content

[0005] This utility model provides a building engineering repair and caulking device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a building engineering repair and caulking device, including a base frame, and further comprising:

[0008] The casters are installed at the four corners of the bottom of the base frame;

[0009] A push handle is fixed to one side of the top of the base frame, and a control box is installed at the top of the push handle, while a battery box connected to the base frame is provided at the bottom of the push handle.

[0010] The tank is mounted on the top of the base frame, and a stirring rod is rotatably connected inside the tank. A stirring motor with an output shaft end connected to the stirring rod is provided at the bottom of the tank.

[0011] The cylinder cover is detachably installed on the top of the tank, and a water inlet is installed on one side of the top of the tank.

[0012] A cleaning structure is provided at the top of the tank body. The cleaning structure includes a top frame fixed to the top of the tank body, a transmission assembly at the bottom of the top frame, a connecting rod at the bottom of the transmission assembly, a scraper fixed to the bottom of the connecting rod, and a reinforcing ring fixed inside the scraper.

[0014] A support frame is installed on one side of the cement pump, and a grouting pipe is detachably installed on the top of the support frame. A connecting hose connected to the cement pump is installed at the bottom of the grouting pipe.

[0015] The flow-stopping structure is installed on the outside of the grouting pipe to prevent grout from overflowing during the grouting process.

[0016] The above technical solution involves starting a mixing motor to agitate the slurry, keeping it in a flowing state, and then starting a cement pump to extract the slurry from inside the tank and inject it into the gap through a connecting hose and grouting pipe, thereby repairing the gap.

[0017] Furthermore, the transmission assembly includes a fixed frame fixed to the bottom end of the top frame, transmission gears rotatably connected to both sides of the bottom end of the fixed frame, a main gear installed on the top of the stirring rod and meshing with the transmission gears, an upper housing rotatably connected to the outside of the fixed frame, a gear ring installed on the inner side wall of the upper housing and meshing with the transmission gears, and a lower housing fixed to the bottom end of the upper housing and connected to the connecting rod.

[0018] The above technical solution uses a stirring rod to drive the main gear to rotate, which in turn causes the lower shell to drive the scraper to rotate on the inner wall of the tank, thus cleaning the slurry adhering to the inner wall of the tank.

[0019] Furthermore, the main gear is connected to the gear ring via a transmission gear, and the stirring rod passes through the lower housing and is connected to the main gear.

[0020] Through the above technical solution, the stirring rod drives the gear ring to rotate via the main gear and the transmission gear.

[0021] Furthermore, the scraper has a spiral shape and a sliding structure is formed between the scraper and the tank body.

[0022] The above technical solution improves the mixing effect of slurry by using a spiral scraper to stir the slurry up and down during rotation.

[0023] Furthermore, the flow-stopping structure includes a baffle sleeved on the outside of the grouting pipe, a guide rod fixed to one side of the baffle, a connecting plate slidably connected to the outside of the guide rod, a telescopic spring installed between the connecting plate and the baffle, and a threaded sleeve rotatably connected to one side of the connecting plate.

[0024] The above technical solution uses a baffle to block the slurry gushing out of the crack, and the position of the baffle is adjusted by rotating the screw sleeve.

[0025] Furthermore, the outer wall of the grouting pipe is provided with external threads, and the inside of the threaded sleeve is provided with internal threads that cooperate with the external threads.

[0026] By rotating the screw sleeve, the screw sleeve moves left and right along the threads on the surface of the grouting pipe, thus adjusting the position of the baffle.

[0027] The above-described solution of this utility model has at least the following beneficial effects:

[0028] 1. This utility model uses a stirring rod to drive the main gear to rotate, which in turn causes the lower shell to drive the scraper to rotate on the inner wall of the tank. This achieves the inner wall cleaning function of the device, effectively removing impurities such as mortar and sealant adhering to the inner wall of the tank. This facilitates subsequent cleaning and maintenance of the device by the staff, and also helps the materials to be mixed more evenly, thus improving the performance of the sealant.

[0029] 2. This utility model uses a baffle to block the grout flowing out of the crack. By rotating the screw sleeve, the position of the baffle is adjusted, thereby realizing the grout overflow prevention function of this device, effectively sealing the gap, preventing the grout material from leaking out during the injection process, and thus ensuring that the grout material can be accurately filled into the target gap.
