Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically a grouting device for prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings assembled on-site using prefabricated components. The advantages of this type of construction include rapid construction speed, less susceptibility to weather conditions, labor savings, and improved building quality. Due to its fast construction speed and low production costs, prefabricated buildings have been rapidly adopted.

[0003] When manufacturing precast concrete components for prefabricated buildings, concrete needs to be injected into the mold of the precast component. After curing, the concrete component is formed. The prior art, Chinese Patent Publication No. CN212359143U, discloses a grouting device for prefabricated buildings. In this technical solution, a grouting pipe is used to inject mortar into the mold of the precast component. However, since the concrete mortar falls into the mold by its own weight when flowing in the grouting pipe, the mortar may adhere to the inner wall of the grouting pipe and cannot fall quickly. After the mortar adhering to the inner wall of the grouting pipe cures, the actual inner diameter of the grouting pipe will decrease, which will reduce the amount of mortar injected into the grouting pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a grouting device for prefabricated buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated building grouting device, comprising:

[0007] A storage bin with multiple support legs at the bottom, and an upper grouting pipe is fixedly connected to the bottom of the storage bin;

[0008] A fixing plate is fixedly connected to multiple of the support legs. The fixing plate is located directly below the upper grouting pipe. The end face of the fixing plate is provided with a through hole-shaped clearance groove.

[0009] The lower grouting pipe is inserted through the clearance groove. The outer diameter of the lower grouting pipe is smaller than the inner diameter of the clearance groove, and the lower end of the upper grouting pipe and the upper end of the lower grouting pipe are both equipped with a corrugated pipe.

[0010] Multiple swaying units are disposed between the outrigger and the lower grouting pipe, the swaying units being used to drive the lower grouting pipe to move horizontally.

[0011] Furthermore, two retaining rings are fixedly fitted around the periphery of the lower grouting pipe from top to bottom, and the opposing surfaces of the two retaining rings respectively abut against the upper and lower surfaces of the fixing plate.

[0012] Furthermore, the swaying unit includes an electromagnet fixed to the outer wall of the support leg, and a fixing post is fixed to the outer wall of the lower grouting pipe. A fixing ring is fixedly sleeved on one end of the fixing post facing the electromagnet, and the fixing ring is used in conjunction with the electromagnet.

[0013] Furthermore, a spring is wound around the fixed column, and the two ends of the spring in the direction of elastic force respectively elastically abut against the fixed ring and the support leg, and the spring is located between the fixed ring and the electromagnet.

[0014] Furthermore, a top cover is installed on the top of the storage bin, and the top cover is provided with a feed pipe. A fixed bin is coaxially fixed to the lower end face of the top cover. The bottom half of the fixed bin is open and the other half is closed. A screen is connected to the open part of the bottom of the fixed bin. A drive shaft is rotatably connected to the upper end face of the top cover. The drive shaft is driven to rotate by a motor installed on the top of the top cover. A mounting sleeve is coaxially sleeved on the part of the drive shaft that passes through the fixed bin. A rotating plate is fixed to the periphery of the mounting sleeve. The edge of the rotating plate away from the drive shaft slides in contact with the inner wall of the fixed bin. The rotating plate forms a collection cavity between the closed part of the bottom of the fixed bin. The rotating plate and the open part of the bottom of the fixed bin form a screening cavity. The screening cavity is in communication with the interior of the storage bin. A slide is fixed to the periphery of the fixed bin. The slide extends out of the storage bin and is in communication with the interior of the collection cavity.

[0015] Furthermore, a vibration unit is connected to the lower end of the drive shaft.

[0016] Furthermore, the vibration unit includes a locking ring fixed to the bottom of the fixed chamber, the lower end of the drive shaft coaxially extends through the locking ring, a floating ring is sleeved on the lower end of the drive shaft, the floating ring is keyed to the periphery of the drive shaft, a connecting post is fixed to the upper end face of the floating ring, a vibrating plate is fixed to the upper end of the connecting post, and a lifting assembly for driving the floating ring to reciprocate vertically is provided on the drive shaft.

[0017] Furthermore, the lifting assembly includes a limiting ring fixedly sleeved on the lower end of the drive shaft, a return spring wound around the drive shaft, and the two ends of the return spring elastically abutting against the floating ring and the limiting ring respectively in the direction of the spring force. Two fixing pins are fixedly connected to the lower end face of the locking ring, and a ball is rotatably embedded in the lower end of the fixing pin. Multiple arc-shaped protrusions are fixedly connected to the upper end face of the floating ring, and the ball rolls alternately on the arc-shaped protrusions and the upper end face of the floating ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up an upper grouting pipe, a lower grouting pipe, and a corrugated pipe, when the mortar flows from the upper grouting pipe into the lower grouting pipe and then into the external mold, the shaking unit drives the lower grouting pipe to move randomly on the horizontal plane, thereby shaking off the mortar adhering to the inner wall of the lower grouting pipe and reducing the adhesion of mortar to the inner wall of the lower grouting pipe.

[0020] 2. By setting up a rotating plate, a screen, and a fixed chamber, the screen is used to screen and filter the mortar fed into the storage chamber through the feed pipe, and to screen out the larger stones. Then, by rotating the plate, the stones left on the screen are driven to the collection chamber and then fall into the slide, thus avoiding the impact of larger stones on the manufacturing accuracy of the mold.

[0021] 3. The rotation of the drive shaft causes the balls to roll on the upper surface of the arc-shaped protrusion and the floating ring. Combined with the elastic resistance of the return spring against the floating ring, the floating ring can move vertically back and forth. This causes the vibrating plate to intermittently strike the bottom of the fixed chamber, which in turn causes the screen to vibrate. This causes the rotating plate to vibrate the mortar on the screen when it drives away the stones, so that the mortar can quickly pass through the screen and fall into the storage chamber.

[0030] 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.

[0031] Please see Figures 1-7This utility model provides a technical solution: a prefabricated building grouting device, including a storage chamber 4 with four support legs 10 at the bottom, an upper grouting pipe 5 fixedly connected to the bottom of the storage chamber 4, the upper grouting pipe 5 communicating with the interior of the storage chamber 4, and a fixing plate 7 connected to the four support legs 10, the fixing plate 7 being located directly below the upper grouting pipe 5, the end face of the fixing plate 7 having a through-hole relief groove, a lower grouting pipe 9 passing through the relief groove, the outer diameter of the lower grouting pipe 9 being smaller than the inner diameter of the relief groove, and the lower end of the upper grouting pipe 5... A corrugated pipe 6 is installed at the upper end of both the upper grouting pipe 5 and the lower grouting pipe 9. The corrugated pipe 6 allows the upper grouting pipe 5 and the lower grouting pipe 9 to be in a continuous state. Two retaining rings 11 are fixedly fitted around the periphery of the lower grouting pipe 9 from top to bottom. The opposing surfaces of the two retaining rings 11 abut against the upper and lower end faces of the connecting fixing plate 7, respectively. The opposing surfaces of the two retaining rings 11 and the lower grouting pipe 9 form an annular groove 19. The fixing plate 7 engages with the annular groove 19, thereby allowing the lower grouting pipe 9 to be connected to the fixing plate 7 and to be able to move freely in any horizontal plane. The system moves in the desired direction. Each support leg 10 has an electromagnet 13 fixedly connected to its outer wall. A fixing post 15 is fixedly connected to the outer wall of the lower grouting pipe 9. A fixing ring 14 is fixedly fitted onto the end of the fixing post 15 facing the electromagnet 13. The fixing ring 14 works in conjunction with the electromagnet 13. The fixing ring 14 is made of any one of iron, cobalt, or nickel. A spring 8 is wound around the fixing post 15. The two ends of the spring 8, in the direction of its elastic force, elastically abut against the fixing ring 14 and the support leg 10, respectively. The spring 8 is located between the fixing ring 14 and the electromagnet 13. When the electromagnet 13 is energized, it will generate a magnetic attraction force on the fixed ring 14, thereby driving the fixed ring 14 to move in the direction of the electromagnet 13. This will cause the spring 8 corresponding to the fixed ring 14 to be compressed, and the other springs 8 to be stretched, so that the springs 8 accumulate elastic potential energy. When the electromagnet 13 is de-energized, the elastic potential energy of the springs 8 is released, which will drive the lower grouting pipe 9 to slide on the surface of the fixed plate 7 through the two retaining rings 11, thereby allowing the lower grouting pipe 9 to swing randomly.

[0032] The storage silo 4 is topped with a cover 3, which has a feed pipe 2 connected to an external mortar conveying device via a pipeline. A fixed silo 17 is coaxially fixed to the lower end face of the cover 3. The bottom of the fixed silo 17 is half open and half closed. A screen 20 is connected to the open portion of the bottom of the fixed silo 17. A drive shaft 23 is rotatably connected to the upper end face of the cover 3. The drive shaft 23 is driven to rotate by a motor 1 mounted on the top of the cover 3. The portion of the drive shaft 23 that passes through the fixed silo 17 is coaxially fitted with a mounting bracket. A mounting sleeve 21 is fitted with a rotating plate 16 fixedly attached to its periphery. The edge of the rotating plate 16 away from the drive shaft 23 slides in contact with the inner wall of the fixed chamber 17. The rotating plate 16 forms a collection cavity 18 between the closed portion at the bottom of the fixed chamber 17 and the open portion at the bottom of the fixed chamber 17, forming a screening cavity 22. The screening cavity 22 communicates with the interior of the storage chamber 4. A slide rail 12 is fixedly attached to the periphery of the fixed chamber 17, extending out of the storage chamber 4 and communicating with the interior of the collection cavity 18. Figure 2 As shown, when the mortar is injected, the rotating plate 16 rotates to the dividing line between the collection chamber 18 and the screening chamber 22. When feeding, the mortar is fed into the fixed chamber 17 through the feed pipe 2, and then falls into the collection chamber 18. The mortar is screened through the screen 20 so that larger stones in the mortar cannot pass through the screen 20 and remain on the screen 20.

[0033] A locking ring 25 is fixedly connected to the bottom of the fixed chamber 17. The lower end of the drive shaft 23 coaxially extends out of the locking ring 25. A floating ring 28 is sleeved on the lower end of the drive shaft 23. The floating ring 28 is keyed to the periphery of the drive shaft 23. A connecting post 32 is fixedly connected to the upper end of the floating ring 28. A vibrating plate 24 is fixedly connected to the upper end of the connecting post 32. A limit ring 29 is fixedly sleeved on the lower end of the drive shaft 23. A return spring 30 is wound around the drive shaft 23. The two ends of the return spring 30 in the direction of the elastic force are respectively paired with... The floating ring 28 and the limiting ring 29 are elastically abutted. Two fixing pins 26 are fixed to the lower end face of the locking ring 25. The lower end of the fixing pin 26 is rotatably fitted with a ball 27. Multiple arc-shaped protrusions 31 are fixed to the upper end face of the floating ring 28. The ball 27 rolls alternately on the arc-shaped protrusions 31 and the upper end face of the floating ring 28. An inclined surface is provided between one end of the arc-shaped protrusion 31 and the end face of the floating ring 28, so that the ball 27 can smoothly roll from the inclined surface to the upper surface of the arc-shaped protrusion 31.

[0034] The working principle of this utility model is as follows: The external mortar conveying device conveys mortar to the feed pipe 2 and falls into the collection chamber 18. Then, under its own weight, the mortar can pass through the screen 20. Larger stones cannot pass through the screen 20 and remain on the screen 20. As the mortar passes through the screen 20, it enters the upper grouting pipe 5 and then enters the lower grouting pipe 9 through the corrugated pipe 6. The power supply of the four electromagnets 13 is alternately turned on by the external control cabinet, so that the electromagnets 13 generate magnetism, which in turn generates magnetic attraction force on the fixed ring 14, thereby driving the fixed ring 14 to move in the direction of the electromagnet 13. This causes the spring 8 corresponding to the fixed ring 14 to be compressed, and the other springs 8 to be stretched, so that the springs 8 accumulate elastic potential energy. When the electromagnet 13 is de-energized, the elastic potential energy of the springs 8 is released, which drives the lower grouting pipe 9 to slide on the surface of the fixed plate 7 through the two retaining rings 11, so that the lower grouting pipe 9 can swing randomly.

[0035] After the mortar has been injected for a period of time, first turn off the mortar conveying device, then start motor 1. The output shaft of motor 1 rotates, causing drive shaft 23 to rotate. When drive shaft 23 rotates, it drives rotating plate 16 to rotate, causing rotating plate 16 to drive the stones left on screen 20 to collection chamber 18. During the rotation of drive shaft 23, since drive shaft 23 and floating ring 28 are keyed, floating ring 28 rotates synchronously, which in turn causes fixed pin 26 to drive ball bearings 27 to roll alternately on the upper end face of floating ring 28 and the upper surface of arc-shaped protrusion 31. Specifically, when ball bearings 27 roll from the upper end face of floating ring 28 from the inclined plane to the upper surface of arc-shaped protrusion 31, the floating ring will... 28 moves downwards and compresses the return spring 30. Then, as the drive shaft 23 rotates, the ball 27 rolls from the upper surface of the arc-shaped protrusion 31 to the upper end face of the floating ring 28, thereby causing the return spring 30 to change from a compressed state to an extended state, and driving the floating ring 28 to move upwards quickly. This causes the vibrating plate 24 to move upwards quickly and strike the bottom of the fixed chamber 17, generating a large vibration on the bottom of the fixed chamber 17, so that the mortar remaining on the screen 20 can be quickly shaken off. When the rotating plate 16 rotates 180°, the stones in the screening chamber 22 will be driven to the collection chamber 18, so that the stones fall from the collection chamber 18 onto the slide 12, where workers collect the stones.
