Description

Technical Field

[0002] Concrete has a wide range of applications in the construction field. Concrete contains raw materials such as sand, stone and water, which are mixed in a certain proportion. During use, concrete needs to be poured in a designated area and then formed into a relatively solid object after cooling.

[0003] In the process of construction projects, it is often necessary to produce and cast prefabricated reinforced concrete structures. It is necessary to first mix raw materials such as cement, sand, stone, etc. according to a proportion, and add an appropriate amount of admixtures to prepare concrete that meets the design requirements. Then, pour the concrete in the mold of the prefabricated structure. During the pouring process, it is usually necessary to use a vibrating device to vibrate the concrete to ensure that the concrete is uniform and dense.

[0004] The prior art discloses a concrete pouring device for construction engineering, including a filling hopper and a feeding barrel, the feeding barrel is used for conveying mixed concrete, the outer surface of the feeding barrel is connected with a telescopic hose, the top end of the telescopic hose is connected with the filling hopper, the end of the feeding barrel away from the telescopic hose is connected with a pouring assembly, the position of the pouring assembly away from the feeding barrel is fixedly connected with a knocking assembly, and the inner surface of the feeding barrel is rotatably connected with a spiral rotating rod.

[0005] When pouring the concrete prefabricated structural parts, the concrete pouring device mentioned in the above prior art needs to place the prefabricated structural part mold in the unloading area, and then simply vibrate the poured concrete through the vibrating assembly installed at the bottom. Although it can play a certain vibrating role, it still has the following shortcomings:

[0006] 1. During pouring, the vibrator is simply inserted into the concrete for vibration. It is difficult to achieve slight up and down floating after insertion. The actual vibration effect is poor, and the concrete is not vibrated evenly, which leads to more bubbles in the concrete, thus affecting the pouring quality of prefabricated structural parts.

[0007] 2. If the concrete is vibrated only after pouring, there may be many bubbles in the concrete before pouring, which may easily reduce the pouring quality of the prefabricated structural parts;

[0008] 3. Simply relying on manual placement of molds is inefficient, and it is difficult to combine automatic loading of the molds with automatic floating vibration, resulting in low actual casting efficiency of precast concrete structures. Summary of the invention

[0024] S2 During the concrete pouring process, the casting mold is horizontally conveyed to the lower part of the pouring hopper by the mold conveyor. During the conveying process of the casting mold, the valve of the discharge port at the lower end of the pouring hopper is opened, so that the concrete in the casting hopper enters the pre-casting vibrating mechanism, and the concrete is pre-vibrated by the pre-casting vibrating mechanism;

[0025] S3 When the front end of the casting mold moves to below the discharge port of the casting hopper, the concrete pre-vibrated in the pre-casting vibrating mechanism is injected downward into the casting mold.

[0050] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0051] A concrete pouring device for construction engineering, mainly used for the production and pouring of prefabricated concrete structural parts, such as concrete cover plates, concrete beams, concrete wall panels, etc.;

[0052] like Figure 1 As shown, the device includes a pouring hopper 1 and a mold conveyor 2. The pouring hopper 1 is mounted on the outlet end of the mold conveyor 2 through a bracket 4. The pouring mold 5 is conveyed to the bottom of the discharge port of the pouring hopper 1 through the mold conveyor 2. A pre-pouring vibrating mechanism 3 is installed at the discharge port of the lower end of the pouring hopper 1. The pre-pouring vibrating mechanism 3 is used to pre-vibrate the concrete before discharging, so that the concrete is more uniform before discharging, thereby reducing bubbles in the discharging concrete, helping to improve the actual vibration effect, and thus improving the pouring quality;

[0053] It also includes a material hoist 11, which is installed above the inlet end of the mold conveyor 2 through a support frame. The discharge port of the material hoist 11 is inclined upward and communicated with the upper end of the inner cavity of the casting hopper 1. The mixed concrete can be obliquely transferred upward to the casting hopper 1 through the material hoist 11 to complete the feeding operation, and at the same time, it does not affect the transmission of the casting mold 5 from the inlet end of the mold conveyor 2;

[0054] A height-adjustable post-casting vibrating mechanism 6 and a floating mechanism 7 are installed on one side of the bracket 4 close to the outlet end of the mold conveyor 2. The post-casting vibrating mechanism 6 is installed on the movable end of the floating mechanism 7. The vibrating end of the post-casting vibrating mechanism 6 is arranged downward and inserted into the concrete for vibration. The post-casting vibrating mechanism 6 in the working state is driven by the floating mechanism 7 to float and vibrate up and down.

[0055] After pouring, a vibrating plate assembly 8 is installed on the vibrating mechanism 6, and the vibrating plate assembly 8 is used to assist in vibrating the poured products with different pouring thicknesses;

[0056] During pouring, by adjusting the height of the post-pouring vibrating mechanism 6 and the floating mechanism 7, the vibrating end of the post-pouring vibrating mechanism 6 is inserted into the concrete in the casting mold 5 below, and the traditional vibration treatment can be performed by the vibration of the post-pouring vibrating mechanism 6, and then the post-pouring vibrating mechanism 6 is driven by the floating mechanism 7 to float up and down, so that the concrete is vibrated evenly up and down, and the casting mold 5 is transported by the mold conveyor 2 to achieve comprehensive and uniform vibration of the concrete in the casting mold 5, which can reduce bubbles in the concrete, thereby improving the casting quality of the concrete prefabricated structural parts. The casting mold 5 is automatically transported by the mold conveyor 2, combined with the automatic floating vibration of the post-pouring vibrating mechanism 6 and the floating mechanism 7, which can effectively improve the actual casting efficiency, thereby accelerating the construction progress of the construction project.

[0057] Specifically, Figure 2 As shown, the pre-casting vibrating mechanism 3 includes a pre-vibrating box 31, a feeding pipe 32, a vibrating blade 33 and a first vibrating motor 34. The pre-vibrating box 31 is installed at the lower end of the discharge port of the casting hopper 1, and the feeding pipe 32 is installed at the bottom of the pre-vibrating box 31. The casting hopper 1, the pre-vibrating box 31 and the feeding pipe 32 are interconnected. The vibrating blade 33 is arranged in the inner cavity of the pre-vibrating box 31 and is driven to vibrate by the first vibrating motor 34 to pre-vibrate the concrete before feeding.

[0058] like Figure 4 As shown, there are multiple feed pipes 32 and they are evenly distributed along the length direction of the pre-vibration box 31, and the number of vibrating blades 33 is consistent with the number of feed pipes 32 and corresponds one to one, so as to realize multi-channel pre-vibration pouring, which is beneficial to improve the uniformity of concrete distribution;

[0059] Furthermore, if Figure 2 As shown, the vibrating blade 33 is in the shape of a spiral blade and is driven to vibrate by a first vibrating motor 34 installed outside the pre-vibrating box 31. The spiral blade design can improve the vibration uniformity of the vibrating blade 33 in the pre-vibrating box 31.

[0060] Specifically, Figure 3 As shown, the post-casting vibrating mechanism 6 includes a second vibrating motor 61, a connecting rod 62, and a vibrating rod 63. The second vibrating motor 61 is installed on the movable end of the floating mechanism 7, the connecting rod 62 is installed on the output shaft of the second vibrating motor 61, and the vibrating rod 63 is installed at the lower end of the connecting rod 62 and is perpendicular to the conveying surface of the mold conveyor 2. The second vibrating motor 61 generates vibration, and the vibration is transmitted to the vibrating rod 63 through the connecting rod 62, so that the vibrating rod 63 can vibrate the poured concrete.

[0061] Furthermore, if Figure 4As shown, there are multiple connecting rods 62 and they correspond one to one with multiple discharge pipes 32. A vibrating rod 63 is installed at the lower end of each connecting rod 62, so that multiple vibrating rods 63 can vibrate concrete poured in multiple channels at the same time. Vibrating around the pouring port can improve the uniformity of vibration, make the concrete more compact, and reduce the generation of bubbles.

[0062] Specifically, Figure 3 As shown, the vibrating plate assembly 8 includes a movable ring 81, a vibration transmission rod 82, and a vibrating plate 83. The movable ring 81 is slidably mounted on the connecting rod 62. One end of the vibration transmission rod 82 is connected to a side of the movable ring 81 close to the discharge port of the mold conveyor 2. The other end of the vibration transmission rod 82 extends downward and is connected to the vibrating plate 83. The vibrating plate 83 is horizontally arranged and is pressed on the upper surface of the prefabricated structure during operation. When the vibrating rod 63 is inserted into the concrete, the vibrating plate 83 is driven to press on the upper surface of the concrete after pouring. The vibration is transmitted to the vibrating plate 83 through the movable ring 81 and the vibration transmission rod 82, so that the upper surface of the concrete is vibrated and leveled by the vibrating plate 83, which is beneficial to improving the pouring quality.

[0063] Furthermore, the outer diameter of the connecting rod 62 is smaller than the outer diameter of the vibrating rod 63, and the outer surface of the connecting rod 62 is installed with a limit strip 64 arranged along its height, and a sleeve hole matching the outer periphery of the connecting rod 62 is provided in the middle of the movable ring 81, and the movable ring 81 is sleeved on the connecting rod 62 through the sleeve hole, and a limit groove matching the limit strip 64 is provided on the inner wall of the sleeve hole, and the movable ring 81 is slidably sleeved with the limit strip 64 through the limit groove. Such a design limits the radial displacement of the movable ring 81, so that the movable ring 81 and the connecting rod 62 are more tightly assembled, which facilitates the transmission of vibration, thereby improving the uniformity of the vibration of the vibrating plate 83 on the upper surface of the concrete;

[0064] Furthermore, a pressure plate 84 is arranged parallel to the lower surface of the vibrating plate 83, and the upper end surface of the pressure plate 84 is connected to the lower end surface of the vibrating plate 83 through a spring. There are multiple springs and they are evenly distributed. Such a design enables the pressure plate 84 to evenly transmit the vibration force to the upper surface of the concrete, which helps to improve the leveling effect.

[0065] When the concrete pouring thickness is high, the pressing plate 84 will drive the vibrating plate 83, the vibration transmission rod 82 and the movable ring 81 to move upward, and the movable ring 81 will move upward along the connecting rod 62 and the limiting strip 64, so as to be suitable for concrete pouring operations of various thicknesses.

[0066] Specifically, Figure 3As shown, the floating mechanism 7 includes a box body 71, a movable rod 72, an end cover 73, a reset spring 74, and a cam 75. The box body 71 is installed on the bracket 4 and is height-adjustable. The movable rod 72 is movably sleeved on the bottom of the box body 71. The upper end of the movable rod 72 extends into the box body 71 and is installed with the end cover 73. The lower end surface of the end cover 73 is connected to the bottom of the inner cavity of the box body 71 through the reset spring 74. The lower end of the movable rod 72 extends to the bottom of the box body 71 and is connected to the top of the post-casting vibrating mechanism 6. The cam 75 is rotatably installed above the inner cavity of the box body 71 and is driven by a motor. The outer peripheral bottom of the cam 75 abuts against the upper end surface of the end cover 73.

[0067] The cam 75 is driven by the motor to rotate, so that the protrusion of the cam 75 is in intermittent contact with the upper end of the end cover 73. When the protrusion is in contact with the upper end of the end cover 73, the end cover 73 is squeezed downward to drive the movable rod 72 and the post-casting vibrating mechanism 6 to move downward, and the reset spring 74 is in a compressed state. When the protrusion is not in contact with the end cover 73, the reset spring 74 returns to its original state and drives the movable rod 72 and the end cover 73 to move upward, so that the post-casting vibrating mechanism 6 moves upward and resets, thereby realizing the up and down floating vibration of the post-casting vibrating mechanism 6, which is conducive to improving the vibration uniformity of the concrete and thus improving the casting quality;

[0068] It should be noted that there are multiple protrusions on the outer periphery of the cam 75, so as to increase the number of up and down floating times of the vibrating mechanism 6 after pouring, thereby improving the uniformity of vibration.

[0069] Specifically, Figure 1 and Figure 4 As shown, a lift 10 is installed on one side of the bracket 4 close to the outlet end of the mold conveyor 2. The lift 10 is an electric slide rail, and the slider of the electric slide rail is arranged on the side away from the casting hopper 1. The floating mechanism 7 is installed on the slider of the electric slide rail. The lift 10 can also be a cylinder, an electric cylinder or an electric screw in the prior art. The lift 10 drives the floating mechanism 7 to rise and fall, thereby adjusting the height of the post-casting vibrating mechanism 6 to facilitate the insertion and removal of the post-casting vibrating mechanism 6.

[0070] It should be noted that the power of the lift 10 is regulated by an external controller, so that the downward movement speed of the vibrating mechanism 6 after pouring is greater than the upward movement speed, thereby realizing the fast insertion and slow withdrawal of the vibrating mechanism 6 after pouring, which is beneficial to the actual pouring and vibrating operation;

[0071] Furthermore, a control switch 9 is installed at the bottom of one side of the bracket 4 close to the discharge port of the mold conveyor 2. When the front end of the casting mold 5 moves to the control switch 9, the control switch 9 generates a high-frequency electrical signal and transmits it to the external controller, and the external controller controls the elevator 10 to move downward, so that the post-casting vibrating mechanism 6 is inserted into the concrete at the front end of the casting mold 5. When the rear end of the casting mold 5 leaves the control switch 9, the control switch 9 generates a low-frequency electrical signal and transmits it to the external controller, and the external controller controls the elevator 10 to move upward, so that the post-casting vibrating mechanism 6 is pulled out from the concrete at the rear end of the casting mold 5.

[0072] It should be noted that the control switch 9 may be an inductive switch or a mechanical switch, and is preferably a photoelectric proximity switch.

[0073] A pouring method of a concrete pouring device for construction engineering, the specific steps are as follows:

[0074] S1 injects the mixed concrete into the casting hopper 1 through the injection equipment, so that the inner cavity of the casting hopper 1 is gradually filled with concrete;

[0075] S2 During the concrete pouring process, the casting mold 5 is horizontally conveyed to the lower part of the discharge port of the casting hopper 1 by the mold conveyor 2. During the conveying process of the casting mold 5, the valve of the discharge port at the lower end of the casting hopper 1 is opened, so that the concrete in the casting hopper 1 enters the pre-casting vibrating mechanism 3, and the concrete is pre-vibrated by the pre-casting vibrating mechanism 3;

[0076] S3 When the front end of the casting mold 5 moves to below the discharge port of the casting hopper 1, the concrete pre-vibrated in the pre-casting vibrating mechanism 3 is injected downward into the casting mold 5. With the continuous conveying of the mold conveyor 2, the casting mold 5 is gradually filled with concrete.

[0077] S4 During the pouring process, the front end of the pouring mold 5 moves to the bottom of the post-pouring vibrating mechanism 6, and the post-pouring vibrating mechanism 6 and the floating mechanism 7 are driven downward by the elevator 10, so that the vibrating rod 63 is quickly inserted into the concrete at the front end of the pouring mold 5, and the second vibrating motor 61 drives the connecting rod 62 and the vibrating rod 63 to vibrate, and the concrete is vibrated again;

[0078] S5 When the vibrating rod 63 is inserted into the concrete, the pressing plate 84 will press on the upper surface of the concrete. When the concrete pouring thickness is high, the pressing plate 84 will drive the vibration transmission rod 82 to move upward, and the vibration transmission rod 82 will drive the movable ring 81 to move upward along the connecting rod 62 and the limit bar 64, and the vibration will be transmitted to the vibrating plate 83 and the pressing plate 84 through the connecting rod 62, so as to realize the auxiliary vibration of the upper end surface of the concrete precast structure;

[0079] S6 During the vibration process of the vibrating rod 63, the cam 75 is driven by the motor to rotate, so that the protrusion of the cam 75 is in intermittent contact with the upper end of the end cover 73. When the protrusion is in contact with the upper end of the end cover 73, the end cover 73 is squeezed downward to drive the movable rod 72 and the post-casting vibrating mechanism 6 to move downward, and the reset spring 74 is in a compressed state. When the protrusion is not in contact with the end cover 73, the reset spring 74 returns to its original state and drives the movable rod 72 and the end cover 73 to move upward, so that the post-casting vibrating mechanism 6 moves up and resets, realizing the up and down floating vibration of the post-casting vibrating mechanism 6.

[0080] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
