A concrete placing device

Abstract

This invention discloses a concrete pouring device, relating to the field of concrete pouring technology. The invention includes a support frame, with a housing fixed to the inner wall of the support frame. A transmission pipe is fixedly inserted through the outer wall of the housing, and a feeding pump for conveying concrete from the transmission pipe is installed on the outer wall of the transmission pipe. This invention utilizes the cooperation of a winding roller, a long rope, an elastic circular plate, an elastic block, a second long rope, a fixed block, and the second winding roller to cause the elastic circular plate to push the concrete remaining inside the transmission pipe to move synchronously. This ultimately allows the concrete to be moved out of the discharge port of the transmission pipe, avoiding the problem that, in winter nights, due to low temperatures, the concrete remaining inside the transmission pipe becomes harder and more viscous, or even completely solidifies inside the pipe, blocking it and making it difficult for the pumping system to continue operating the next day, or even damaging the pumping equipment.

Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, specifically to a concrete pouring device. Background Technology

[0002] A concrete pouring device is a piece of equipment used to uniformly pour concrete to a designated location. It is widely used in construction engineering and typically consists of a concrete delivery pipe, a pumping system, a vibrator, and a control system. Through the pumping system, the concrete is efficiently transported to the construction site for construction.

[0003] Chinese patent CN116677202B discloses a concrete pouring device, including a base and a shock-absorbing support mounted on the base; a first mounting pipe connected to the shock-absorbing support, with a feed pipe fixed to the top of the first mounting pipe, the feed pipe being inclinedly mounted on the first mounting pipe and having a feed inlet on its wall; a sealing part mounted on the feed pipe for sealing the feed inlet; and a pusher cylinder slidably connected to the first mounting pipe. The base is provided with a driving part for driving the pusher cylinder to slide back and forth. This patent removes all concrete remaining in the transmission pipe by adding a cylindrical rubber column with an outer diameter not less than the inner diameter of the transmission pipe inside the transmission pipe and using high-pressure air to push the rubber column to move in the transmission pipe, thereby reducing cleaning costs, reducing water waste, and avoiding environmental pollution.

[0004] However, the current concrete pouring device has the following problems: the high-pressure air that moves the rubber column can only discharge concrete from shorter or less curved transmission pipes. When the transmission pipe is longer or has more bends, the rubber column may get stuck or unable to pass smoothly in the curved parts due to its irregular shape or increased friction, causing blockage or stagnation. Furthermore, concrete may remain inside the transmission pipe, which can become harder and more viscous, or even completely solidify inside the pipe, blocking it and making it difficult for the pumping system to continue operating the next day, or even damaging the pumping equipment. Therefore, we propose a concrete pouring device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a concrete pouring device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete pouring device, comprising a support frame, a frame body fixed to the inner wall of the support frame, a transmission pipe fixedly passing through the outer wall of the frame body, a feeding pump for conveying concrete from the transmission pipe being installed on the outer wall of the transmission pipe, a discharge device being installed on the outer wall of the transmission pipe, the discharge device comprising a fixing frame fixed to the outer wall of the transmission pipe, and a winding roller rotatably mounted on the inner wall of the fixing frame, the winding roller being driven by the output shaft of a motor. The motor is fixed to the outer wall of the frame. A long rope is fixed to the outer wall of the first winding roller. An elastic circular plate is fixed to the end of the long rope away from the first winding roller. Multiple elastic blocks are fixed to the outer wall of the elastic circular plate. A second long rope is fixed to the side of the elastic circular plate away from the first long rope. A fixing block is fixed to the outer wall of the frame. A second winding roller is rotatably mounted on the side of the fixing block. The end of the second long rope away from the elastic circular plate is fixed to the outer wall of the second winding roller. The second winding roller is driven by a handle. A long plate for moving the elastic blocks is fixed to the inner wall of the frame.

[0007] According to the above technical solution, a protective frame is fixed to the bottom of the inner wall of the frame, and a protective tube for protecting the second long rope is fixedly inserted through the side of the protective frame.

[0008] According to the above technical solution, the circumference of the elastic circular plate is equal to the circumference of the inner wall of the transmission pipe.

[0009] According to the above technical solution, the inner wall of the fixing frame is provided with an anti-damage device, which includes a threaded rod. The threaded rod is rotatably installed on the inner wall of the fixing frame. One end of the threaded rod is fixed with a pulley, and the outer wall of the winding roller is fixed with a pulley. A belt is connected between the pulley and the pulley. A threaded block is threadedly connected to the outer wall of the threaded rod. A vertical block is fixed to the bottom of the threaded block, and a conical hollow block is fixed to the side of the vertical block. The inner wall of the conical hollow block is in contact with the outer wall of the long rope.

[0010] According to the above technical solution, an elastic telescopic rod II is fixed to the side of the vertical block, a support block is fixed to the telescopic end of the elastic telescopic rod II, an impact rod is fixed to the side of the support block, a hemispherical block I is fixed to the side of the support block, a U-shaped block is fixed to the bottom of the fixing frame, and multiple hemispherical blocks II are fixed to the side of the U-shaped block.

[0011] According to the above technical solution, the multiple hemispherical blocks II are located on the displacement trajectory of hemispherical block I, and the conical hollow block is located on the displacement trajectory of the impact rod.

[0012] According to the above technical solution, an auxiliary device is provided on the outer wall of the transmission pipeline. The auxiliary device includes a ring, the inner wall of which is fixed to the outer wall of the transmission pipeline. Multiple track arc rings are fixed on the outer wall of the ring. A moving block is slidably installed on the inner wall of each of the multiple track arc rings. An elastic telescopic rod is fixed to the bottom of the moving block. An umbrella-shaped block is fixed to the bottom of the elastic telescopic rod. An arc-shaped rod is fixed to the side of the moving block. A pull block is fixed to the end of the arc-shaped rod away from the moving block.

[0013] According to the above technical solution, the umbrella-shaped block is located on the displacement trajectory of the elastic block and the elastic circular plate.

[0014] This invention provides a concrete pouring device. It has the following beneficial effects:

[0015] (1) The present invention uses the combination of a winding roller 1, a long rope 1, an elastic circular plate, an elastic block, a long rope 2, a fixed block, and a winding roller 2 to make the elastic circular plate push the concrete remaining inside the transmission pipe to move synchronously, so that the concrete can be moved out of the discharge port of the transmission pipe together. This avoids the problem that at night in winter, due to the low temperature, the concrete remaining inside the transmission pipe will become harder and more viscous, or even completely solidify in the pipe, blocking the pipe and making it difficult for the pumping system to continue working the next day, or even damaging the pumping equipment.

[0016] (2) The present invention uses the cooperation of threaded rod, pulley one, pulley two, belt, threaded block, vertical block and conical hollow block to make the conical hollow block move back and forth to make the long rope one neatly arranged when it is contracted on the winding roller one, thereby avoiding the long rope one from getting knotted on the winding roller one, which would prevent the long rope one from being released smoothly during use. In addition, the conical hollow block can scrape off the concrete on the surface of the long rope one, avoiding the problem of the long rope one being worn by stones in the concrete when winding. At the same time, through the cooperation of conical hollow block, elastic telescopic rod two, support block, impact rod, hemispherical block one, U-shaped block and hemispherical block two, the reset of the impact rod will hit the conical hollow block, causing the conical hollow block to vibrate, thereby accelerating the speed at which the concrete falls from the conical hollow block and the long rope, avoiding the problem of excessive accumulation of concrete at the conical hollow block, which would make it difficult for the long rope one to be stuck and difficult to pass through the conical hollow block.

[0017] (3) In this invention, the combination of the circular ring, the track arc ring, the moving block, the elastic telescopic rod three, the umbrella-shaped block, the elastic circular plate, and the elastic block allows the umbrella-shaped block to stretch the elastic telescopic rod three when it moves downward, thereby providing support for the elastic circular plate and preventing the elastic circular plate from exiting the discharge port of the transmission pipe at too high a speed, which could lead to a dangerous situation. At the same time, the combination of the track arc ring, the moving block, the elastic telescopic rod three, the umbrella-shaped block, the arc rod, and the pull block allows the movement of the elastic telescopic rod three to prevent the umbrella-shaped block from being below the transmission pipe. This prevents the umbrella-shaped block from being subjected to the impact force of the concrete when it exits the discharge port of the transmission pipe, which would cause the elastic telescopic rod three to remain in the final stretched state. Over time, this would damage the elastic telescopic rod three and reduce its service life. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-8One embodiment of the present invention is as follows: a concrete pouring device includes a support frame 1, a frame 2 fixed to the inner wall of the support frame 1, a transmission pipe 3 fixedly passing through the outer wall of the frame 2, a feeding pump 4 for conveying concrete from the transmission pipe 3 being provided on the outer wall of the transmission pipe 3, a discharge device 5 being provided on the outer wall of the transmission pipe 3, the discharge device 5 including a fixing frame 51, the fixing frame 51 being fixed to the outer wall of the transmission pipe 3, a winding roller 52 being rotatably mounted on the inner wall of the fixing frame 51, the winding roller 52 being driven by the output shaft of a motor, the motor being fixed to the outer wall of the fixing frame 51, a long rope 53 being fixed to the outer wall of the winding roller 52, an elastic circular plate 54 being fixed to the end of the long rope 53 away from the winding roller 52, a plurality of elastic blocks 55 being fixed to the outer wall of the elastic circular plate 54, a long rope 56 being fixed to the side of the elastic circular plate 54 away from the long rope 53, and a fixing block 57 being fixed to the outer wall of the frame 2, the side of the fixing block 57 being rotatably mounted The system is equipped with a second winding roller 58, and a long rope 56 is fixed at one end away from the elastic circular plate 54 to the outer wall of the second winding roller 58. The second winding roller 58 is driven by a handle. A long plate 59 for moving the elastic block 55 is fixed to the inner wall of the frame 2. A protective frame 511 is fixed to the bottom of the inner wall of the frame 2. A protective tube 510 for protecting the long rope 56 is fixed through the side of the protective frame 511. The circumference of the elastic circular plate 54 is equal to the circumference of the inner wall of the transmission pipe 3. With the above structure, the elastic circular plate 54 will push the concrete remaining inside the transmission pipe 3 to move synchronously, so that the concrete can be moved out of the discharge port of the transmission pipe 3 together. This avoids the problem that the concrete remaining inside the transmission pipe 3 will become harder and more viscous, or even completely solidify inside the pipe, blocking the pipe and making it difficult for the pumping system to continue working the next day, or even damaging the pumping equipment, when the temperature is low at night in winter.

[0029] The inner wall of the fixing frame 51 is provided with an anti-damage device 6, which includes a threaded rod 61. The threaded rod 61 is rotatably mounted on the inner wall of the fixing frame 51. One end of the threaded rod 61 is fixed with a pulley 62. The outer wall of the winding roller 52 is fixed with a pulley 63. A belt 64 is connected between the pulley 62 and the pulley 63. A threaded block 65 is threadedly connected to the outer wall of the threaded rod 61. A vertical block 66 is fixed to the bottom of the threaded block 65. A conical hollow block 67 is fixed to the side of the vertical block 66. The inner wall of the hollow block 67 is in contact with the outer wall of the long rope 53. With the above structure, the back and forth movement of the conical hollow block 67 will neatly arrange the long rope 53 when it is contracted on the winding roller 52, thereby avoiding the long rope 53 from getting knotted on the winding roller 52, which would prevent the long rope 53 from being released smoothly during use. In addition, the conical hollow block 67 can scrape off the concrete on the surface of the long rope 53, avoiding the problem of the long rope 53 being worn by stones in the concrete when it is being wound.

[0030] A second elastic telescopic rod 68 is fixed to the side of the vertical block 66. A support block 69 is fixed to the telescopic end of the second elastic telescopic rod 68. An impact rod 610 is fixed to the side of the support block 69. A hemispherical block 611 is fixed to the side of the support block 69. A U-shaped block 612 is fixed to the bottom of the fixing frame 51. Multiple hemispherical blocks 613 are fixed to the side of the U-shaped block 612. The multiple hemispherical blocks 613 are located on the displacement trajectory of the hemispherical block 611. A conical hollow block 67 is located on the displacement trajectory of the impact rod 610. With the above structure, the reset of the impact rod 610 will impact the conical hollow block 67, causing the conical hollow block 67 to vibrate. This will accelerate the speed at which concrete falls from the conical hollow block 67 and the long rope 53, avoiding excessive accumulation of concrete at the conical hollow block 67, which would make it difficult for the long rope 53 to be caught and pass through the conical hollow block 67.

[0031] In operation, after the daily concrete pouring is completed, the staff starts the motor corresponding to the winding roller 52, causing the winding roller 52 to rotate. The rotation of the winding roller 52 will retract the long rope 53, thus the long rope 53 will drive the elastic circular plate 54 to move. The elastic circular plate 54 will move along the long plate 59 into the transmission pipe 3 through the elastic block 55. At the same time, the elastic circular plate 54 will pull the long rope 56 during the movement. When the elastic circular plate 54 moves into the transmission pipe 3, it will push the concrete remaining in the transmission pipe 3 to move synchronously, so that the concrete can be moved out of the discharge port of the transmission pipe 3 together. This avoids the problem that in winter nights, due to the low temperature, the concrete remaining in the transmission pipe 3 will become harder and more viscous, or even completely solidify in the pipe, blocking the pipe and making it difficult for the pumping system to continue working the next day, or even damaging the pumping equipment.

[0032] When the frame 2 and the transmission pipe 3 are needed the next day, the workers turn the winding roller 2 58 by turning the handle, which causes the winding roller 2 58 to retract the long rope 2 56. The retraction of the long rope 2 56 will drive the elastic circular plate 54 and the elastic block 55 to move into the protective frame 511, and then the concrete is poured into the frame 2.

[0033] When the winding roller 52 rotates, it drives the pulley 63 to rotate. The rotation of the pulley 63, in turn, drives the pulley 62 via the belt 64. The rotation of the pulley 62 drives the threaded rod 61 to rotate. The rotation of the threaded rod 61 causes the threaded block 65 to move back and forth along the inner wall of the fixed frame 51. The back and forth movement of the fixed frame 51 causes the vertical block 66 to move back and forth. The back and forth movement of the vertical block 66 causes the conical hollow block 67 to move back and forth. The back and forth movement of the conical hollow block 67 keeps the long rope 53 neatly arranged when it is wound on the winding roller 52, thus preventing the long rope 53 from getting knotted on the winding roller 52, which would prevent the long rope 53 from being unable to be released smoothly during use. At the same time, the conical hollow block 67 can scrape off the concrete on the surface of the long rope 53, preventing the long rope 53 from being worn by stones in the concrete during winding. The back and forth movement of the vertical block 66 drives the elastic telescopic rod 68. The movement of the elastic telescopic rod 68 causes the support block 69 to move, which in turn causes the impact rod 610 and hemispherical block 611 to move. The movement of hemispherical block 611 will then contact hemispherical block 613, causing it to move the support block 69 and impact rod 610 away from the conical hollow block 67, and stretching the elastic telescopic rod 68. When the movement of hemispherical block 611 no longer contacts hemispherical block 613... At point 613, the elastic telescopic rod 68 will use its own elasticity to drive the support block 69, the impact rod 610, and the hemispherical block 611 to reset. The reset of the impact rod 610 will hit the conical hollow block 67, causing the conical hollow block 67 to vibrate, thereby accelerating the speed at which concrete falls from the conical hollow block 67 and the long rope 53. This avoids the problem of excessive accumulation of concrete at the conical hollow block 67, which would make it difficult for the long rope 53 to be stuck and pass through the conical hollow block 67.

[0034] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, an auxiliary device 7 is provided on the outer wall of the transmission pipe 3. The auxiliary device 7 includes a ring 71, the inner wall of the ring 71 is fixed to the outer wall of the transmission pipe 3, and a plurality of track arc rings 72 are fixed on the outer wall of the ring 71. A moving block 73 is slidably installed on the inner wall of each of the plurality of track arc rings 72. An elastic telescopic rod 74 is fixed to the bottom of the moving block 73, and an umbrella-shaped block 75 is fixed to the bottom of the elastic telescopic rod 74. An arc-shaped rod 76 is fixed to the side of the moving block 73, and a pull block 77 is fixed to the end of the arc-shaped rod 76 away from the moving block 73. The umbrella-shaped block 75 is located on the displacement trajectory of the elastic block 55 and the elastic circular plate 54. With the above-described structure, the downward movement of the umbrella-shaped block 75 stretches the elastic telescopic rod 74, thereby providing support for the elastic circular plate 54. This prevents the elastic circular plate 54 from exiting the discharge port of the transmission pipe 3 at excessive speed, which could lead to a dangerous situation. Furthermore, the movement of the elastic telescopic rod 74 ensures that the umbrella-shaped block 75 is no longer positioned below the transmission pipe 3. This prevents the umbrella-shaped block 75 from being subjected to the impact force of the concrete when it exits the discharge port of the transmission pipe 3, which would cause the elastic telescopic rod 74 to remain in a stretched state over time. This would damage the elastic telescopic rod 74 and reduce its service life.

[0035] In use, when the elastic circular plate 54 and the elastic block 55 are about to exit from the discharge port of the transmission pipe 3, the elastic block 55 will preferentially insert into the slot of the umbrella-shaped block 75 and drive the umbrella-shaped block 75 downwards. At this time, the downward movement of the umbrella-shaped block 75 will stretch the elastic telescopic rod 74, thereby providing support for the elastic circular plate 54 and preventing the elastic circular plate 54 from exiting the discharge port of the transmission pipe 3 at too high a speed, which could lead to a dangerous situation. When the transmission pipe 3 needs to be used, the operator pulls the pull block 77, which will drive the moving block 73 along the inner wall of the track arc ring 72 away from the arc ring 72 via the arc rod 76. The movement of the ring 71 causes the moving block 73 to move, which in turn moves the elastic telescopic rod 74. The movement of the elastic telescopic rod 74 causes the umbrella-shaped block 75 to no longer be below the transmission pipe 3. This prevents the umbrella-shaped block 75 from being subjected to the impact force of the concrete when it comes out of the outlet of the transmission pipe 3, which would cause the elastic telescopic rod 74 to be in a stretched final state. Over time, this would damage the elastic telescopic rod 74 and reduce its service life. When the transmission pipe 3 is not in use, the above operation is reversed so that the umbrella-shaped block 75 is back below the transmission pipe 3.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
