Description

Technical Field

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

[0002] Grouting involves injecting solidifying materials, such as cement, lime, or other chemicals, into the rock and soil within a defined area beneath the foundation to fill cracks and pores, prevent leakage, and improve the integrity, strength, and rigidity of the rock and soil. Grouting is commonly used to create an anti-seepage curtain in water-retaining structures such as gates, dams, and dikes, and is a primary foundation treatment measure for hydraulic structures.

[0003] Patent application number CN202421195203.6 discloses a construction grouting device, which relates to the field of construction grouting and includes a walking cart, wherein a storage tank is fixedly connected to one side of the upper surface of the walking cart, and an end cap is provided at the upper end opening of the storage tank, and a feeding port is provided on one side of the end cap. The end cap is detachably connected to the storage tank via four equally spaced bolt connectors. By moving the position of the fixing sleeve and fixing it via a plug-in assembly, the lower end of the grouting head is now at the optimal height for gap grouting. As the slurry decreases, the control drive assembly drives the scraper and the stirring plate to rotate together inside the storage tank. Due to the inclined design of the scraper, as it rotates, the slurry adhered to the inner wall can be driven downward along the scraper slope to avoid slurry adhesion. The entire operation process is quick and convenient, avoiding hand-held work. At the same time, the slurry adhered to the inner wall of the container can be scraped off to avoid slurry waste.

[0004] When the above-mentioned equipment is in use, the mixed mud will be injected into the ground through the nozzle to fill the cracks and pores in the rock and soil, prevent the foundation from leaking, and improve the integrity, strength and stiffness of the rock and soil. However, after the equipment completes the mixing of the mud, a large number of bubbles will exist in the mud. These bubbles will affect the hardness of the mud, and then affect the integrity, strength and stiffness of the rock and soil after the grouting operation is completed, which is not conducive to construction needs. Summary of the Invention

[0005] The object of the present invention is to provide a construction grouting device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a construction grouting device, comprising a base plate, a universal wheel fixedly connected to the bottom of the base plate, a push plate fixedly connected to the rear side of the base plate, a mixing tank fixedly connected to the top of the base plate, a slurry pump 1 fixedly connected to the outer wall of the mixing tank, the bottom of the slurry pump 1 fixedly connected to the base plate, an end of the slurry pump 1 away from the mixing tank fixedly connected to a feed pipe, a slurry pump 2 fixedly connected to the top of the base plate, an outer wall of the slurry pump 2 fixedly connected to a circulation pipe, and an end of the circulation pipe away from the slurry pump 2 fixedly connected to the mixing tank, further comprising:

[0007] The spraying mechanism includes a shell fixedly connected to the top of the base plate, the outer wall of the shell is fixedly connected to a nozzle, the inner wall of the shell is fixedly connected to a connecting pipe, the end of the connecting pipe away from the shell is fixedly connected to a hose 1, the end of the connecting pipe away from the hose 1 is fixedly connected to a pump slurry machine 2, and the left and right ends of the inner wall of the shell are fixedly connected to expansion pipes. By setting the expansion pipe, the inner diameter of the pipe becomes larger before the mud enters the exhaust component, thereby reducing the passing speed of the mud, making the time for the mud to pass through the exhaust component longer, and improving the exhaust effect of the equipment. At the same time, due to the increase in the inner diameter of the pipeline, there is more reserved space at the top of the mud in the hollow tube 2, which avoids splashing of mud when the equipment shakes.

[0008] According to the above technical solution, the end of the expansion tube on the right side close to the shell is fixedly connected to the nozzle, the end of the expansion tube on the left side close to the shell is fixedly connected to the feed pipe, the ends of the two expansion tubes away from the shell are fixedly connected to hose 2, and the inner wall of the shell is fixedly connected to the shaking component.

[0009] According to the above technical solution, the shaking assembly includes a top plate, the bottom of the top plate is fixedly connected to a connecting plate 1, the inner wall of the connecting plate 1 is rotatably connected to a roller through a bearing, the outer surface of the connecting plate 1 is fixedly connected to a motor, the output end of the motor is fixedly connected to the roller, the outer wall of the roller is provided with a conveyor belt, the inner wall of the connecting plate 1 is fixedly connected to an exhaust assembly, and the bottom of the connecting plate 1 is fixedly connected to a pressure assembly.

[0010] According to the above technical solution, the pressure component includes an elastic component, the top of the elastic component is fixedly connected to the connecting plate 1, the bottom of the elastic component is fixedly connected to the connecting plate 2, the top of the connecting plate 2 is fixedly connected to the bracket, the inner wall of the bracket is rotatably connected to the roller through the bearing, and the roller is rotatably connected to the roller through the conveyor belt. By setting the pressure component, since the exhaust component is constantly shaking when working, the conveyor belt cannot effectively drive the auxiliary component to rotate, and pressure is applied to the conveyor belt through the pressure component to ensure the connection between the conveyor belt and the auxiliary component, avoid power interruption, and ensure the normal operation of the equipment.

[0011] According to the above technical solution, the exhaust component includes an elastic ring 1, the outer wall of the elastic ring 1 is fixedly connected to the connecting plate 1, the inner wall of the elastic ring 1 is fixedly connected to the hollow tube 1, both ends of the hollow tube 1 are fixedly connected to the connecting ring 1, the outer wall of the connecting ring 1 is rotatably connected to the auxiliary component through a bearing, the bottom of the hollow tube 1 is fixedly connected to the discharge pipe, and the bottom of the discharge pipe is fixedly connected to the hose 1.

[0012] According to the above technical solution, a hollow tube 2 is provided inside the hollow tube 1, and an elastic ring 2 is fixedly connected to the outer wall of the hollow tube 2. The outer wall of the elastic ring 2 is fixedly connected to the connecting plate 1, and both ends of the hollow tube 2 are fixedly connected to the hose 2. A notch is provided at the top of the hollow tube 2, and a connecting ring 2 is fixedly connected to the outer wall of the hollow tube 2. By setting an exhaust component, when the hollow tube 2 is shaken, the notch at the top allows the gas in the mud to have space for discharge, thereby preventing the discharged bubbles from remaining in the tube, resulting in a deterioration in the degassing effect of the equipment. At the same time, since a notch is provided at the top of the hollow tube 2, a layer of hollow tube 1 is again provided on the outside of the hollow tube 2 to prevent the mud from scattering from the equipment during shaking, and the scattered mud is transported back to the mixing tank through the discharge pipe to avoid waste of mud.

[0013] According to the above technical solution, the auxiliary component includes a rotating ring, the outer wall of the rotating ring is rotatably connected to the connecting ring 1 through a bearing, the inner wall of the rotating ring is rotatably connected to the connecting ring 2 through a bearing, the outer wall of the rotating ring is provided with a sleeve, and the sleeve is rotatably connected to the roller through a conveyor belt. By setting up the auxiliary component, the eccentric plate rotates under the drive of the shaking roller, and then drives the entire exhaust component to shake. Through the shaking method, the mud passing through the hollow tube 2 is shaken and exhausted, so that the mud discharged from the nozzle can greatly reduce the bubble content, thereby improving the grouting effect of the equipment.

[0014] According to the above technical solution, the outer wall of the rotating ring is fixedly connected to an eccentric plate, the end of the rotating ring away from the eccentric plate is fixedly connected to a scraper, and the inner wall of the hollow tube one is movably connected to the scraper. By setting an auxiliary component, when the equipment is shaken to exhaust, the scraper will also be driven to move on the inner wall of the hollow tube one, ensuring that the mud discharged from the hollow tube two can quickly enter the discharge pipe, avoiding the mud remaining in the equipment from solidifying and causing the equipment to fail to operate normally, thereby ensuring the stability of the equipment operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention sets an auxiliary component, which drives the eccentric plate to rotate under the drive of the shaking roller, and then drives the entire exhaust component to shake. By shaking, the mud passing through the hollow tube 2 is shaken and exhausted. In this way, the mud discharged from the nozzle can greatly reduce the bubble content, thereby improving the grouting effect of the equipment.

[0017] 2. The present invention provides an exhaust assembly. When the hollow tube 2 is shaken, the notch at the top allows the gas in the mud to be discharged, thereby preventing the discharged bubbles from remaining in the tube, which would result in a poor bubble removal effect of the equipment. At the same time, since there is a notch at the top of the hollow tube 2, a layer of hollow tube 1 is provided on the outside of the hollow tube 2 to prevent the mud from scattering from the equipment during shaking, and the scattered mud is transported back to the mixing tank through the discharge pipe to avoid waste of mud.

[0018] 3. The present invention sets an auxiliary component, which will drive the scraper to move on the inner wall of hollow tube 1 when the equipment is shaking to exhaust, ensuring that the mud discharged from hollow tube 2 can quickly enter the discharge pipe, avoiding the mud remaining in the equipment from solidifying and causing the equipment to be unable to operate normally, thereby ensuring the stability of the equipment operation.

[0019] 4. The present invention sets a pressure component. Since the exhaust component is constantly shaking during operation, the conveyor belt cannot effectively drive the auxiliary component to rotate. The pressure component applies pressure to the conveyor belt to ensure the connection between the conveyor belt and the auxiliary component, avoid power interruption, and ensure the normal operation of the equipment.

[0020] 5. The present invention sets an expansion tube so that the inner diameter of the tube becomes larger before the mud enters the exhaust component, thereby reducing the passing speed of the mud, prolonging the time for the mud to pass through the exhaust component, and improving the exhaust effect of the equipment. At the same time, since the inner diameter of the pipe becomes larger, there is more reserved space at the top of the mud in the hollow tube, avoiding splashing of mud when the equipment shakes.
