Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, specifically a pipeline laying grouting device. Background Technology

[0002] Pipeline grouting equipment is a specialized device used to inject grout around or inside pipelines to reinforce the strata, fill voids, prevent leakage, or improve load-bearing capacity. During pipeline laying, grout is injected into the surrounding strata to improve the strength and stability of the strata and prevent pipeline damage due to geological deformation.

[0003] In the construction of urban underground pipelines, grouting devices can be used to reinforce the strata around the pipelines to prevent damage caused by geological deformation. At the same time, grouting devices can also be used to fill the gaps between the pipelines and the strata, improving the pipelines' sealing and service life.

[0004] Existing grouting devices typically place pre-mixed mortar and cement in a hopper, then use a grouting pump to transport the mortar and cement to a designated location. However, long-term use and observation have revealed that when using a grouting machine, the cement and mortar need to be mixed thoroughly beforehand and placed in the hopper before grouting. This method requires manual mixing, which can lead to uneven mixing, and necessitates a secondary transfer of the mortar and cement, making it cumbersome. Furthermore, when mixing a large quantity at once, the mortar and cement not placed in the hopper are prone to solidification. Therefore, to address these issues, a pipeline laying grouting device is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a pipeline laying grouting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a pipeline laying grouting device, including a grouting machine body, a storage hopper connected to the grouting machine body, a pair of support columns fixed to the grouting machine body, a pair of support plates fixed to the grouting machine body, the support columns and support plates being fixedly connected, a mixing tank fixed to the support plates, a feed inlet on the mixing tank, a motor fixed to the mixing tank, a rotating shaft fixed to the output end of the motor, the rotating shaft and the mixing tank being through-connected and rotatably connected, multiple stirring rods fixed to the rotating shaft, a discharge port at the bottom of the mixing tank, an electronic valve installed at the discharge port, a handrail fixed to the grouting machine body, and a mixing tank fixed to the support plates, a motor fixed to the mixing tank, a rotating shaft fixed to the output end of the motor, and multiple stirring rods fixed to the rotating shaft. Multiple mixing rods are used. When grouting is required, cement mortar and other raw materials are placed in the mixing tank for mixing. After mixing, the cement mortar enters the storage hopper through the discharge port, and then enters the nozzle connected to the grouting machine body. Finally, it reaches the area that needs to be grouted. During use, cement mortar and other raw materials can be directly mixed and put into the storage hopper, reducing the need for manual mixing or the troublesome situation of transferring the mixed materials to the storage hopper again. At the same time, the control box set on the grouting machine body can quantitatively control the discharge port to add mortar cement into the storage hopper, so that the mortar cement that is not added continues to be stored in the mixing tank for mixing, reducing the possibility of mortar cement solidification when a large amount of mortar cement is added to the storage hopper at one time.

[0007] Preferably, multiple mixing blades are fixedly connected to the end of the rotating shaft. The mixing blades are set at a certain angle. By fixing multiple mixing blades to the rotating shaft, the mortar and cement can be further mixed during use, reducing the difficulty of mixing the mortar and cement located at the top and the cement located at the bottom during use.

[0008] Preferably, multiple baffles are fixedly connected to the inner wall of the mixing tank. The baffles are located between a pair of mixing rods. By fixing multiple baffles to the inner wall of the mixing tank, the cement mortar driven by the mixing rods can be disturbed when the mixing rods rotate during use, reducing the situation where the mortar and cement always move along the direction of rotation of the mixing rods and are difficult to mix evenly.

[0009] Preferably, multiple dividing blades are fixedly connected to the stirring rod, and the dividing blades are arranged in an array. By fixing multiple dividing blades to the stirring rod, the mortar and cement can be cut during use, reducing the clumping of cement and mortar and preventing difficulties in uniform mixing.

[0010] Preferably, a scraper is fixedly connected to the end of the rotating shaft. The scraper is located between the rotating shaft and the mixing tank. By fixing the scraper to the end of the rotating shaft, the rotating scraper can scrape off the mortar and cement deposited at the bottom of the mixing tank during use, reducing the situation where the mortar and cement are deposited at the bottom of the mixing tank and are difficult to mix evenly during use.

[0011] Preferably, a pair of material distribution plates are fixedly connected to the stirring rod. The material distribution plates are set at a certain angle. By fixing a pair of material distribution plates to the stirring rod, the movement trajectory of mortar and cement can be further disturbed during use, thereby further reducing the uneven mixing of mortar and cement during use.

[0012] The advantages of this utility model are:

[0013] This utility model provides a pipeline laying grouting device. A mixing tank is fixedly connected to a support plate, a motor is fixedly connected to the mixing tank, a rotating shaft is fixedly connected to the motor output end, and multiple mixing rods are fixedly connected to the rotating shaft. When grouting is required, cement mortar and other raw materials are placed in the mixing tank for mixing. After mixing, the cement mortar enters the storage hopper through the discharge port, then enters the nozzle connected to the grouting machine body, and finally reaches the area requiring grouting. This device allows for direct mixing of cement mortar and other raw materials and their placement into the storage hopper during use, reducing the need for manual mixing or the cumbersome process of transferring the mixed materials back into the storage hopper. Furthermore, the control box on the grouting machine body allows for quantitative control of the discharge port's addition of cement mortar into the storage hopper, ensuring that any unadded cement mortar remains in the mixing tank for further mixing, thus reducing the risk of solidification when a large amount of cement mortar is added to the storage hopper at once.

[0014] This utility model provides a pipeline laying grouting device. By fixing multiple mixing fan blades on the rotating shaft, it can further mix the mortar and cement during use, reducing the difficulty of mixing the mortar and cement in the upper part and the cement in the lower part during use.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figures 1-5As shown, a pipeline laying grouting device includes a grouting machine body 1, a storage hopper 11 connected to the grouting machine body 1, a pair of support columns 12 fixedly connected to the grouting machine body 1, a pair of support plates 13 fixedly connected to the grouting machine body 1, the support columns 12 and support plates 13 being fixedly connected, a mixing tank 14 fixedly connected to the support plates 13, a feed inlet 15 opened on the mixing tank 14, a motor 16 fixedly connected to the mixing tank 14, a rotating shaft 17 fixedly connected to the output end of the motor 16, the rotating shaft 17 and the mixing tank 14 being through-connected and rotatably connected, a plurality of stirring rods 18 fixedly connected to the rotating shaft 17, a discharge port 19 opened at the bottom of the mixing tank 14, an electronic valve being installed on the discharge port 19, the grouting... A handle 110 is fixedly attached to the main body 1. When grouting work is required, the worker first holds the handle 110 and pushes the main body 1 to the designated position. The main body 1 is a New Warrior 511 model. A hose is connected to the nozzle of the main body 1. Then, cement mortar and water are added into the mixing tank 14 through the feed inlet 15 according to the ratio. Then, the motor 16 is turned on through the control box 7 on the main body 1. When the motor 16 is turned on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives the multiple mixing rods 18 fixed on the rotating shaft 17 to rotate accordingly. When the multiple mixing rods 18 rotate, they mix the cement mortar and water inside the mixing tank 14. After mixing is completed, the mixture is discharged through the main body 1. The control box 7 on the upper part opens the electronic valve at the discharge port 19. When the electronic valve at the discharge port 19 is opened, part of the mixed mortar falls from the discharge port 19 into the storage hopper 11. The cement mortar that does not fall into the storage hopper 11 remains inside the mixing tank 14 and is further stirred and allowed to solidify. At this time, the grouting machine body 1 is opened by the control box 7 on the grouting machine body 1. When the grouting machine body 1 is opened, the cement mortar inside the storage hopper 11 is sprayed out from the hose connected to the nozzle on the grouting machine body 1. When the sprayed cement mortar is transported to the pipeline, grouting work is carried out at the pipeline laying location. The mixing tank 14 is fixed to the support plate 13, and the motor 16 is fixed to the mixing tank 14. The rotating shaft 17 is fixed to the output end of the motor 16. Multiple mixing rods 18 are fixedly connected to the shaft 17. When grouting is required using the grouting machine body 1, cement mortar and other raw materials are placed in the mixing tank 14 for mixing. After mixing, the cement mortar enters the storage hopper 11 through the discharge port 19, and then enters the nozzle connected to the grouting machine body 1 from the storage hopper 11, finally reaching the area to be grouted. It can directly mix cement mortar and other raw materials and put them into the storage hopper 11 during use, reducing the need for manual mixing or the use of other equipment to mix and then transfer them back into the storage hopper 11, which is quite troublesome. At the same time, the control box 7 set on the grouting machine body 1 can quantitatively control the discharge port 19 to put mortar and cement into the storage hopper 11.This allows unadded mortar and cement to remain in the mixing tank 14 for further mixing, reducing the likelihood of mortar and cement solidifying when a large amount is added at once, such as from the storage hopper 11.

[0024] Please see Figures 1-5 As shown, multiple stirring blades 2 are fixed to the end of the rotating shaft 17. The stirring blades 2 are set at a certain angle. When the motor 16 is turned on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives the multiple stirring blades 2 to rotate. When the multiple stirring blades 2 rotate, they disturb the mortar and cement raw materials inside the mixing tank 14. When the multiple stirring blades 2 rotate, they form a vortex of water flow that moves towards the bottom of the mixing tank 14. When the vortex reaches the bottom of the mixing tank 14, it contacts the bottom of the mixing tank 14. At this time, due to the resistance, the vortex flows towards the bottom of the mixing tank 14. The vortex spreads around the bottom. As the mixing blades 2 rotate continuously, the vortex moves towards the bottom of the mixing tank 14. Some of the mortar cement is squeezed towards the motor 16 due to the force. At this time, the cement mortar in the upper part of the mixing tank 14 and the cement mortar in the lower part of the mixing tank 14 are forced to exchange, making the mortar cement more uniformly mixed. By fixing multiple mixing blades 2 on the rotating shaft 17, the mortar cement can be further mixed during use, reducing the situation where the mortar cement in the upper part and the cement in the lower part are difficult to mix during use.

[0025] Please see Figures 1-5 As shown, multiple baffles 3 are fixedly attached to the inner wall of the mixing tank 14. The baffles 3 are located between a pair of stirring rods 18. When the stirring rods 18 rotate, they stir and mix the mortar and cement inside the mixing tank 14. At this time, the mortar and cement move with the stirring rods 18. When the mortar and cement move to the designated position, they come into contact with the baffles 3. At this time, some of the mortar and cement passes through the gaps on the baffles 3, and some of the mortar and cement is blocked by the baffles 3 due to resistance and diffuses to the sides of the mixing tank 14. By fixing multiple baffles 3 to the inner wall of the mixing tank 14, the cement mortar driven by the stirring rods 18 can be disturbed when the stirring rods 18 rotate during use, reducing the situation where the mortar and cement always move in the direction of rotation of the stirring rods 18 and are difficult to mix evenly.

[0026] Please see Figures 1-5As shown, multiple dividing blades 4 are fixedly attached to the stirring rod 18. The dividing blades 4 are arranged in an array. When the rotating shaft 17 rotates, it drives the stirring rod 18 to rotate. When the stirring rod 18 rotates, the multiple dividing blades 4 fixedly attached to the stirring rod 18 rotate accordingly. When the dividing blades 4 rotate, they cut the mortar cement in the mixing tank 14. The cut mortar cement is then mixed by the rotating stirring rod 18 and the stirring fan blades 2. By fixing multiple dividing blades 4 to the stirring rod 18, the mortar cement can be cut during use, reducing the clumping of cement mortar and preventing the situation where it is difficult to mix evenly.

[0027] Please see Figures 1-5 As shown, a scraper 5 is fixedly connected to the end of the rotating shaft 17. The scraper 5 is located between the rotating shaft 17 and the mixing tank 14. When the rotating shaft 17 rotates, it drives the scraper 5 to rotate as well. When the scraper 5 rotates, it contacts the bottom of the mixing tank 14 and scrapes off the mortar and cement deposited at the bottom of the mixing tank 14. By fixing the scraper 5 to the end of the rotating shaft 17, the rotating scraper 5 can scrape off the mortar and cement deposited at the bottom of the mixing tank 14 during use, reducing the situation where the mortar and cement are deposited at the bottom of the mixing tank 14 and are difficult to mix evenly during use.

[0028] Please see Figures 1-5 As shown, a pair of material distribution plates 6 are fixedly connected to the stirring rod 18. The material distribution plates 6 are set at a certain included angle. When the motor 16 is turned on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives the stirring rod 18 to rotate accordingly. When the stirring rod 18 rotates, it drives the material distribution plates 6 fixed to the stirring rod 18 to rotate accordingly. When the material distribution plates 6 rotate, they stir the mortar and cement in the mixing tank 14. When the mortar and cement come into contact with the material distribution plates 6, the cement mortar moves along the surface of the material distribution plates 6. At this time, the material distribution plates 6 mix the cement mortar. By fixing a pair of material distribution plates 6 to the stirring rod 18, the movement trajectory of the mortar and cement can be further disturbed during use, and the uneven mixing of mortar and cement during use can be further reduced.

[0029] Working principle: When grouting is required using the grouting machine body 1, the worker first pushes the grouting machine body 1 to the designated position by holding the handle 110. The grouting machine body 1 is a New Warrior 511 model. A hose is connected to the nozzle of the grouting machine body 1. Then, cement mortar and water are added into the mixing tank 14 through the feed inlet 15 according to the ratio. Then, the motor 16 is turned on through the control box 7 on the grouting machine body 1. When the motor 16 is turned on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives the multiple mixing rods 18 fixed on the rotating shaft 17 to rotate accordingly. When the multiple mixing rods 18 rotate, they stimulate the cement mortar inside the mixing tank 14. The mortar is mixed with water. After mixing, the electronic valve at the discharge port 19 is opened through the control box 7 on the grouting machine body 1. When the electronic valve at the discharge port 19 is opened, part of the mixed mortar falls from the discharge port 19 into the storage hopper 11. The cement mortar that does not fall into the storage hopper 11 remains in the mixing tank 14 and is stirred and allowed to solidify. At this time, the grouting machine body 1 is opened through the control box 7 on the grouting machine body 1. When the grouting machine body 1 is opened, the cement mortar in the storage hopper 11 is sprayed out from the hose connected to the nozzle on the grouting machine body 1. When the sprayed cement mortar is transported to the pipeline, the pipeline laying area is grouted.

[0030] When the motor 16 is turned on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives multiple mixing blades 2 to rotate. When the multiple mixing blades 2 rotate, they disturb the mortar and cement raw materials inside the mixing tank 14. When the multiple mixing blades 2 rotate, they form a vortex of water flow and move it towards the bottom of the mixing tank 14. When the vortex reaches the bottom of the mixing tank 14, it contacts the bottom of the mixing tank 14. At this time, due to the resistance, the vortex spreads to the periphery of the bottom of the mixing tank 14. As the mixing blades 2 continue to rotate and the vortex continues to move towards the bottom of the mixing tank 14, some of the mortar and cement are squeezed towards the motor 16 due to the force. At this time, the cement mortar located at the top and bottom of the mixing tank 14 is forced to exchange, making the mortar and cement mix more uniform.

[0031] When the stirring rod 18 rotates, it stirs and mixes the mortar and cement inside the mixing tank 14. At this time, the mortar and cement move with the stirring rod 18. When the mortar and cement move to the designated position, the mortar and cement come into contact with the baffle plate 3. At this time, some of the mortar and cement pass through the gaps on the baffle plate 3, and some of the mortar and cement are resisted and intercepted by the baffle plate 3 and diffuse to the sides of the mixing tank 14.

[0032] When the rotating shaft 17 rotates, it drives the stirring rod 18 to rotate. When the stirring rod 18 rotates, the multiple dividing blades 4 fixed on the stirring rod 18 rotate accordingly. When the dividing blades 4 rotate, they cut the mortar cement in the mixing tank 14. The cut mortar cement is then mixed by the rotating stirring rod 18 and the stirring fan blades 2.

[0033] When the rotating shaft 17 rotates, it drives the scraper 5 to rotate as well. When the scraper 5 rotates, it contacts the bottom of the mixing tank 14 and scrapes off the mortar and cement deposited at the bottom of the mixing tank 14.

[0034] When the motor 16 is turned on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives the stirring rod 18 to rotate as well. When the stirring rod 18 rotates, it drives the material distribution plate 6 fixed on the stirring rod 18 to rotate as well. When the material distribution plate 6 rotates, it stirs the mortar and cement in the mixing tank 14. When the mortar and cement come into contact with the material distribution plate 6, the cement mortar moves along the surface of the material distribution plate 6. At this time, the material distribution plate 6 mixes the cement mortar. It can further disturb the movement trajectory of the mortar and cement during use, and further reduce the uneven mixing of mortar and cement during use.
