Description

Technical Field

[0001] This application relates to the technical field of repair and caulking equipment, and in particular to a repair and caulking equipment for building walls. Background Technology

[0002] Building wall repair and caulking equipment is a professional tool used to repair and fill cracks, holes, and other defects in building walls. It typically consists of a material storage device, a conveying system, and a caulking nozzle. It can accurately deliver caulking material to the cracks or damaged areas of the wall, achieving efficient and uniform caulking and repair through squeezing and spreading methods, thereby restoring the integrity and aesthetics of the wall and improving the building's waterproofing, sound insulation, and other performance characteristics.

[0003] A search revealed Chinese Patent Publication No. CN221373020U, which discloses a wall repair and grouting device. The device includes a supporting base plate and a mixing tank. A support plate is fixedly connected to the top of the supporting base plate, and the mixing tank is fixedly connected to the upper surface of the support plate. A spiral shaft is installed inside the mixing tank, and a cement pump is fixedly installed on one side of the mixing tank. A flexible hose is fixedly installed at the output end of the cement pump, and a scraper plate is fixedly connected to one end of the hose. This wall repair and grouting device, when the servo motor rotates forward, causes the spiral shaft to rotate forward, allowing the concrete to tumble from bottom to top for thorough mixing. When the servo motor rotates in reverse, the spiral shaft rotates in reverse, allowing the concrete to be pressed downwards. This concrete is then supplied to the scraper plate through the hose, exiting from the outlet. The scraper plate fills the wall gaps and smooths the surface simultaneously, thus improving the device's efficiency and practicality.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: Existing wall repair and grouting equipment lacks effective temperature control or insulation design in practical applications, resulting in insufficient adaptability to extreme temperature environments. In low-temperature environments, the cement slurry in the mixing tank and conveying pipeline is prone to freezing or loss of fluidity due to excessively low temperatures. In high-temperature environments, the cement hydration reaction accelerates, and the slurry solidifies rapidly in a short time, leading to problems such as construction interruption, material waste, and equipment pipeline blockage. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a building wall repair and caulking device.

[0006] This application provides a building wall repair and caulking device, which adopts the following technical solution: A building wall repair and caulking device includes a repair and caulking device body, a mixing tank, a scraper plate, and a cement pump. The mixing tank is installed on one side of the top of the repair and caulking device body, and the cement pump is installed on the rear side of the top of the repair and caulking device body. The cement pump is connected to the mixing tank through a pipe and to the scraper plate through a pipe. A heat insulation protection mechanism is installed on the outside of the mixing tank. The heat insulation protection mechanism includes a heat insulation ring, and a protective column is installed on the outside of the heat insulation ring. A cover plate is detachably mounted on the top of the mixing tank, and a heat insulation plate is installed on the top of the cover plate. A temperature detection and conduction mechanism is provided on the outside of the mixing tank.

[0007] The above scheme involves an insulation ring fitted around the outside of the mixing tank to form a ring-shaped insulation layer, reducing the impact of external temperature on the cement slurry inside the tank. Protective columns are fixed to the outside of the insulation ring to enhance the stability and impact resistance of the insulation structure. The cover plate and insulation plate are movably installed on the top of the mixing tank. The insulation plate improves the heat insulation performance of the top of the tank, reducing heat loss or external heat intrusion. A temperature-conducting detection mechanism is used to monitor the temperature inside the tank and regulate the temperature.

[0008] Optionally, the temperature detection and conduction mechanism includes a series of connecting slots, which are arranged at equal intervals. A copper plate is installed on the inner side of the inner wall of the connecting slot, and an installation slot is opened on the outer side of the copper plate. A heating block is installed inside the installation slot, and a one-way heat conduction plate is provided on the outer side of the copper plate. The outer side of the one-way heat conduction plate extends through the insulation ring and the protective column to the outer side of the protective column. A temperature sensor is embedded inside the stirring tank.

[0009] The above scheme involves a connecting groove evenly distributed on the outer wall of the mixing tank, penetrating the tank wall and the insulation ring to form a temperature conduction channel. A copper plate is embedded inside the connecting groove, utilizing the high thermal conductivity of metal to quickly transfer the temperature inside the tank to the outside. A heating block is installed in the mounting groove outside the copper plate, generating heat when energized in low-temperature environments, and transferring heat to the tank through the copper plate to prevent the cement slurry from freezing. A unidirectional heat-conducting plate is located outside the copper plate, penetrating the insulation ring and the protective column to extend to the outside, controlling the unidirectional heat conduction from the inside of the tank to the outside when the temperature inside the tank is high.

[0010] Optionally, the inner side of the unidirectional heat-conducting plate is provided with a movable groove, a heat-conducting rod is movably connected inside the movable groove, a heat-absorbing block is installed inside the heat-conducting rod, an iron block is embedded in the outer side of the heat-absorbing block, and an electromagnetic block is installed on the outer side of the copper plate.

[0011] With the above scheme, the moving groove is opened inside the one-way heat conduction plate to provide a sliding track for the heat conduction rod. The heat conduction rod and the heat absorption block are adjusted so that the heat absorption block is attached to the copper plate. The heat from the copper plate is transferred to the one-way heat conduction plate through the heat conduction rod to achieve temperature conduction. The electromagnetic block is linked with the controller. When the temperature inside the stirring tank is high, it is energized to generate magnetic force to attract the iron block, which drives the suction block to attach to the copper plate to absorb and dissipate heat.

[0012] Optionally, an insulation box is installed on the outside of the electromagnetic block. The insulation box does not shield the magnetic force of the electromagnetic block. The insulation box is installed on the outside of the copper plate. A buffer spring is provided between the iron block and the electromagnetic block. The two ends of the buffer spring are fixedly connected to the iron block and the electromagnetic block, respectively.

[0013] The above solution uses a non-magnetic material to wrap the electromagnetic block in the insulation box, which isolates the influence of external temperature on the electromagnetic performance and ensures magnetic stability. The buffer spring connects the iron block and the electromagnetic block and can push the iron block to reset and move.

[0014] Optionally, the inner side of the copper plate is coated with an anti-stick layer, which is a polytetrafluoroethylene coating, and a heat-conducting ring is installed on the outer side of the heat-conducting rod, the surface of which slides in contact with the inside of the moving groove.

[0015] The above solution includes an anti-stick layer to prevent cement slurry from adhering to the inside of the copper plate, facilitating post-construction cleaning and preventing residual cement from solidifying and affecting heat conduction efficiency. The heat conduction ring, fitted on the outside of the heat conduction rod, slides and fits into the moving groove, effectively transferring the heat from the heat conduction rod to the unidirectional heat conduction plate, while preventing the heat conduction rod from separating from the moving groove.

[0016] Optionally, a sealing ring is installed between the unidirectional heat-conducting plate and the insulation ring and protective column, and a heat-conducting plate is installed on one side of the temperature sensor. The heat-conducting plate is installed inside the mixing tank to conduct heat and protect the temperature sensor.

[0017] The above solution fills the gap between the unidirectional heat-conducting plate, the insulation ring, and the protective column with a sealing rubber ring to prevent dust, moisture, or heat from leaking through the gaps, thereby improving the equipment's sealing performance. The heat-conducting sheet prevents the temperature sensor from being directly connected to the cement inside the mixing tank. At the same time, the heat-conducting sheet can conduct heat to the inside of the mixing tank, making it convenient for the temperature sensor to detect the temperature.

[0018] Optionally, the heating block is electrically connected to a controller via a wire. The controller is installed at the bottom of the front of the protective column and is electrically connected to the electromagnetic block via a wire. A protective box is provided on the outside of the controller and is installed on the front of the protective column.

[0019] With the above solution, the controller is installed at the bottom of the protective column, receives temperature sensor signals, and controls the start and stop of the heating block and the electromagnetic block. The protective box protects the controller from cement dust and moisture corrosion, ensuring the stable operation of the circuit system.

[0020] In summary, this application includes the following beneficial technical effects: This invention, by setting up components such as a heat insulation ring, a heating block, and a temperature sensor, and through the cooperation of the annular heat insulation layer and the active heating structure, monitors and adjusts the temperature inside the mixing tank in real time, making the cement slurry less likely to freeze or solidify rapidly under extreme environments, thereby ensuring construction continuity and reducing material waste.

[0021] This invention, by setting up components such as an anti-stick layer, a sealing ring, and a heat-conducting ring, reduces cement residue and improves component durability through the cooperation of the anti-stick layer and the sealed heat-conducting structure. This makes the equipment easier to clean and maintain, reduces the risk of blockage, and thus achieves the effects of extending service life and improving operational convenience.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a building wall repair and grouting device.

[0026] Please see Figure 1A wall repair and caulking device includes a repair and caulking device body 1, a mixing tank 2, a scraper plate 3, and a cement pump 4. The mixing tank 2 is installed on one side of the top of the repair and caulking device body 1, and the cement pump 4 is installed on the rear side of the top of the repair and caulking device body 1. The cement pump 4 is connected to the mixing tank 2 through a pipe and to the scraper plate 3 through a pipe.

[0027] Please see Figure 3 The mixing tank 2 is equipped with a heat insulation protection mechanism 5 on its outer side. The heat insulation protection mechanism 5 includes a heat insulation ring 51, which is fitted onto the outer side of the mixing tank 2 to form a ring-shaped heat insulation layer, reducing heat transfer and maintaining a relatively stable temperature inside the mixing tank 2. A protective post 52 is installed on the outer side of the heat insulation ring 51 to protect it from damage caused by external impacts. A cover plate 53 is detachably installed on the top of the mixing tank 2, which facilitates cleaning, maintenance, and material addition operations inside the mixing tank 2. A heat insulation plate 54 is installed on the top of the cover plate 53 to further improve the heat insulation performance of the top of the mixing tank 2 and reduce heat loss from the top. A temperature detection and conduction mechanism 6 is provided on the outer side of the mixing tank 2 to detect the temperature conduction. Mechanism 6 includes several connecting grooves 61, which are arranged at equal intervals. A copper plate 62 is installed on the inner side of the inner wall of the connecting groove 61. The copper plate 62 utilizes the good thermal conductivity of copper to conduct heat quickly. An installation groove 63 is opened on the outer side of the copper plate 62. A heating block 64 is installed inside the installation groove 63. The heating block 64 generates heat when energized and transfers the heat to the mixing tank 2 through the copper plate 62 to prevent the sealant from freezing. A one-way heat conduction plate 65 is provided on the outer side of the copper plate 62. The outer side of the one-way heat conduction plate 65 passes through the insulation ring 51 and the protective column 52 in sequence and extends to the outer side of the protective column 52. A temperature sensor 66 is embedded in the inside of the mixing tank 2 to monitor the temperature of the sealant in the mixing tank 2 in real time and transmit the temperature signal to the controller 18.

[0028] Please see Figure 2 A sealing ring 16 is installed between the unidirectional heat-conducting plate 65, the insulation ring 51, and the protective column 52. A heat-conducting plate 17 is installed on one side of the temperature sensor 66. The heat-conducting plate 17 is installed inside the mixing tank 2 to conduct heat and protect the temperature sensor 66. The heating block 64 is electrically connected to the controller 18 through wires. The controller 18 is installed at the bottom of the front of the protective column 52.

[0029] Please see Figure 4A movable groove 7 is provided on the inner side of the unidirectional heat conduction plate 65. A heat conduction rod 8 is movably connected inside the movable groove 7. A heat absorption block 9 is installed on the inner side of the heat conduction rod 8. The heat conduction rod 8 transfers the heat absorbed by the heat absorption block 9 to the unidirectional heat conduction plate 65 to achieve heat conduction. An iron block 10 is embedded on the outer side of the heat absorption block 9. An electromagnetic block 11 is installed on the outer side of the copper plate 62. The electromagnetic block 11 generates or loses magnetic force, thereby controlling the movement of the iron block 10 and the heat conduction rod 8 and regulating the heat conduction.

[0030] The inner side of the copper plate 62 is coated with an anti-stick layer 14, which is a polytetrafluoroethylene coating. This layer prevents the filling material in the mixing tank 2 from adhering to the copper plate 62, making it easier to clean after construction. A heat-conducting ring 15 is installed on the outer side of the heat-conducting rod 8. The surface of the heat-conducting ring 15 slides and fits against the inside of the moving groove 7. The heat-conducting ring 15 enhances the heat conduction performance of the heat-conducting rod 8 and also plays a guiding and stabilizing role when the heat-conducting rod 8 slides.

[0031] An insulation box 12 is installed on the outside of the electromagnetic block 11. The insulation box 12 does not shield the magnetic force of the electromagnetic block 11. The insulation box 12 is installed on the outside of the copper plate 62. A buffer spring 13 is provided between the iron block 10 and the electromagnetic block 11. The two ends of the buffer spring 13 are fixedly connected to the iron block 10 and the electromagnetic block 11 respectively. The controller 18 is electrically connected to the electromagnetic block 11 through a wire. A protective box 19 is provided on the outside of the controller 18. The protective box 19 is installed on the front of the protective column 52.

[0032] The implementation principle of a building wall repair and grouting device according to an embodiment of this application is as follows: Before starting the equipment, add an appropriate amount of cement and other grouting materials into the mixing tank 2, and cover it with a cover plate 53 with a heat insulation plate 54. The heat insulation ring 51 is fitted on the outside of the mixing tank 2, forming a stable heat insulation structure together with the protective column 52 to reduce the influence of the outside temperature on the material inside the tank. The heat insulation plate 54 on the cover plate 53 further improves the heat insulation performance of the top of the tank and prevents heat loss.

[0033] When the equipment is running, the temperature sensor 66 starts to monitor the temperature of the cement slurry in the mixing tank 2 in real time. When the environment is low temperature, the temperature sensor 66 transmits the temperature signal to the controller 18. After receiving the signal, the controller 18 starts the heating block 64. The heating block 64 is installed in the mounting groove 63 on the outside of the copper plate 62. After being powered on, it generates heat. The heat is quickly transferred through the copper plate 62 with high thermal conductivity. Since the heat absorption block 9 is not in contact with the copper plate 62 at this time, the heat conduction plate 65 will not dissipate heat quickly. The heat can only be conducted unidirectionally to the mixing tank 2, thereby raising the temperature of the cement slurry in the tank and preventing it from freezing.

[0034] During temperature regulation, the sealing ring 16 ensures the seal between the one-way heat conduction plate 65 and the insulation ring 51 and the protective column 52, preventing dust and moisture from entering and avoiding heat leakage. The heat conduction plate 17 efficiently conducts the temperature inside the mixing tank 2 to the temperature sensor 66, while protecting the temperature sensor 66 from direct contact with cement, ensuring the accuracy of temperature monitoring and the service life of the sensor. The controller 18 is installed on the bottom front of the protective column 52, and its outer protective box 19 effectively protects the controller 18 from cement dust and moisture corrosion, ensuring the stable operation of the circuit system.

[0035] When the temperature inside the mixing tank 2 is too high, the controller 18 controls the electromagnetic block 11 to be energized. The electromagnetic block 11 generates magnetic force, attracting the iron block 10, which drives the heat-conducting rod 8 and the heat-absorbing block 9 connected to it to move towards the copper plate 62. The heat-absorbing block 9 adheres to the copper plate 62, transferring the heat on the copper plate 62 to the unidirectional heat-conducting plate 65 through the heat-conducting rod 8, and then conducting it to the outside to achieve heat dissipation. When the temperature drops to a suitable range, the electromagnetic block 11 is de-energized. Under the action of the buffer spring 13, the iron block 10, the heat-conducting rod 8 and the heat-absorbing block 9 are reset. The anti-stick layer 14 on the inner side of the copper plate 62 can prevent cement slurry from adhering, making it easy to clean after construction. The heat-conducting ring 15 is sleeved on the outside of the heat-conducting rod 8, which can efficiently transfer the heat transferred by the heat-conducting rod 8 to the unidirectional heat-conducting plate 65, and prevent the heat-conducting rod 8 from separating from the moving groove 7, ensuring the stability of heat conduction.

[0036] After the materials are mixed, the cement pump 4 starts and transports the cement slurry in the mixing tank 2 to the scraper plate 3 through the pipeline. The scraper plate 3 fills and smooths the gaps in the building wall, realizing the function of wall repair. Throughout the process, the equipment effectively solves the defect of existing equipment that is prone to problems with cement slurry under extreme temperature conditions through the coordinated work of various components, ensuring the smooth progress of construction.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
