Description

Technical Field

[0001] The invention relates to the technical field of concrete forming devices, and in particular to a vibrating forming table for concrete and a vibrating method. Background Art

[0002] The concrete vibrating molding table is a device specially used for manufacturing concrete products. It uses vibration to make the concrete evenly distributed in the mold and expel the air, forming and vibrating it in the mold. It is widely used in the construction industry. The concrete vibrating molding table provides vibration force through a motor, hydraulic system or pneumatic system. The staff places the molds on the vibrating molding table in order, sprays the demoulding machine onto the mold surface, and then starts the concrete placing machine, which pours concrete into the mold. Then the vibration mechanism of the concrete vibrating molding table vibrates, so that the concrete in the mold fits the mold, and as the concrete vibrates, the bubbles in the concrete are discharged from the concrete. After the vibration is completed, the mold and the concrete are taken out of the concrete vibrating molding table together, and the concrete is taken out of the mold after it solidifies and forms. When the concrete placing machine is spreading the concrete and pouring it into the mold, the concrete spreading will be uneven, with some molds having more concrete and some molds having less concrete. The staff needs to use a shovel to shovel the more concrete into the less concrete mold to prevent the more concrete from falling from the mold onto the concrete vibration forming table during vibration, and the less concrete from being insufficient. Manual operation with a shovel is time-consuming and wastes manpower, which causes limitations.

[0003] To this end, we propose a vibrating forming table and a vibrating method for concrete. Summary of the invention

[0022] Refer to the instruction manual Figure 1 , 2 and 4. In the present embodiment, the detection mechanism 2 comprises a support block 21, a block No. 1 22, a block No. 2 23 and a detection rod 24; a telescopic electric push rod 25 is fixedly connected to the mounting block 17; the output end of the telescopic electric push rod 25 is fixedly connected to the support block 21; the block No. 1 22 is fixedly connected to the support block 21; the block No. 2 23 is mounted on the mounting block 17; sliding grooves 26 are provided on the blocks No. 1 22 and No. 2 23; a pressure sensor No. 1 27 is fixedly connected in the sliding groove 26; a detection rod 24 is slidably connected in the sliding groove 26; a detection spring 28 is fixedly connected between the detection rod 24 and the pressure sensor No. 1 27.

[0023] Refer to the instruction manual Figure 3 and 5 In this embodiment, the equal distribution mechanism 3 includes a No. 3 block 31, a mobile electric push rod 32 and an extraction tube 33; a sliding block 34 is fixedly connected to the mounting block 17; the No. 3 block 31 is slidably connected to the sliding block 34; the mobile electric push rod 32 is fixedly connected to the sliding block 34, and the output end of the mobile electric push rod 32 is fixedly connected to the No. 3 block 31; a cavity 35 is provided in the No. 3 block 31; the extraction tube 33 is fixedly connected to the No. 3 block 31 and communicates with the cavity 35; an extraction motor 36 is fixedly connected to the No. 3 block 31; a screw conveying shaft 37 is fixedly connected to the output end of the extraction motor 36; the screw conveying shaft 37 extends into the extraction tube 33.

[0024] In this embodiment, a stirring rod 38 is disposed in the cavity 35 ; the stirring rod 38 is fixedly connected to the screw conveying shaft 37 .

[0025] In the present invention, the staff first places the mold neatly on the support seat 12, then sprays the release agent onto the surface of the mold, then starts the concrete placing machine to pour concrete into the mold, and then the controller controls the telescopic electric push rod 25 to push the support block 21, the No. 1 block 22, the No. 2 block 23 and the detection rod 24 downward, so that the detection rod 24 on the No. 1 block 22 contacts the upper end of the mold, and the detection rod 24 on the No. 2 block 23 contacts the concrete in the mold, and the detection rod 24 moves into the sliding groove 26 and squeezes the detection spring 28, so that the No. 1 pressure sensor 27 is subjected to pressure, and the longer the detection rod 24 contracts into the sliding groove 26, the greater the pressure on the No. 1 pressure sensor 27; due to the different telescopic amounts of the detection rods 24 on the No. 1 block 22 and the No. 2 block 23, when the pressure on the No. 1 pressure sensor 27 on the No. 2 block 23 is less than that on the No. 1 pressure sensor 27, the detection rod 24 on the No. 2 block 23 is pressed. When the pressure of the No. 1 pressure sensor 27 on the No. 1 block 22 is greater than that of the No. 1 block 22, it means that the extension and contraction amount of the detection rod 24 on the No. 2 block 23 is less than that of the detection rod 24 on the No. 1 block 22, that is, the end position of the detection rod 24 on the No. 2 block 23 is lower than the end position of the detection rod 24 on the No. 1 block 22, and the position of the concrete is lower than the top of the mold. According to the pressure difference between the No. 1 pressure sensor 27 on the No. 1 block 22 and the pressure sensor on the No. 2 block 23 at this time, the stiffness coefficient of the detection spring 28 is brought into play, and then according to the stiffness coefficient formula, the difference between the concrete and the top of the mold can be calculated, so that the averaging mechanism 3 replenishes the concrete in the mold according to the difference; on the contrary, when the No. 1 pressure sensor 27 on the No. 2 block 23 is greater than the pressure sensor on the No. 1 block 22, it means that the position of the concrete is higher than the top of the mold, and the averaging mechanism 3 draws the excess concrete out of the mold; In the present invention, when the equalizing mechanism 3 extracts the concrete in the mold, the controller controls the mobile electric push rod 32 to push the third block 31 and the extraction tube 33 downward, so that the extraction tube 33 is inserted into the concrete, and the contact extraction motor 36 rotates forward, driving the screw conveying shaft 37 to rotate, so that the excess concrete in the mold enters the cavity 35, and the extraction motor 36 drives the stirring rod 38 to rotate, stirring the concrete in the cavity 35, so that the concrete in the cavity 35 is not easy to solidify; when the concrete in the mold is to be supplemented, the extraction motor 36 rotates the screw conveying shaft 37 in the opposite direction, so that the concrete in the cavity 35 enters the mold; When the mold is vibrated, the vibration motor 13 drives the eccentric vibration block 14 to rotate, so that the support seat 12 and the mold vibrate; The present invention detects the weight of concrete in the mold by the pressure difference between the detection rods 24 on the No. 1 block 22 and the No. 2 block 23 and the corresponding No. 1 pressure sensor 27, and extracts excess concrete in the mold through the extraction pipe 33 and the screw conveying shaft 37, and guides the concrete into the mold with less concrete, so that the concrete content in the vibration molding table is uniform, and there is no need to manually shovel excess concrete into the mold with less concrete.

[0026] Refer to the instruction manual Figure 2 In this embodiment, a detection ring 4 is fixedly connected to the detection rod 24 on the No. 2 block 23; a rotating rod 41 is hinged on the detection ring 4; a detection block 42 is evenly fixedly connected to the detection ring 4; a No. 2 pressure sensor 43 is fixedly connected inside the detection block 42; a support spring 44 is fixedly connected between the No. 2 pressure sensor 43 and the rotating rod 41.

[0027] In this embodiment, a rotating motor 5 is fixedly connected inside the supporting block 21 ; the second block 23 is rotatably connected to the supporting block 21 ; and the output end of the rotating motor 5 is fixedly connected to the second block 23 .

[0028] In the present invention, when the screw conveying shaft 37 of the equalizing mechanism 3 extracts concrete from the mold, the controller controls the telescopic electric push rod 25 to drive the support block 21, the first block 22 and the second block 23 to move up and down, so that the detection rod 24 on the first block 22 and the second block 23 moves up and down, so that the detection ring 4 and the rotating rod 41 hit the concrete surface back and forth, on the one hand, preventing the detection ring 4 and the rotating rod 41 on the second block 23 from contacting with the concrete. Under the action of gravity and the detection spring 28, The detection rod 24 sinks into the concrete, causing the telescopic depth of the detection rod 24 to change, thereby causing inaccurate detection; while the telescopic electric push rod 25 drives the second block 23, the detection ring 4 and the rotating rod 41 to move up and down, the rotating motor 5 rotates the second block 23 back and forth, causing the detection ring 4 and the rotating rod 41 to swing back and forth, thereby increasing the range of the detection ring 4 and the rotating rod 41 hitting the concrete surface, thereby pressing the fillers such as stones exposed on the concrete surface under the concrete surface, making the concrete surface smoother after solidification; In the present invention, when the detection rod 24 moves downward with the detection ring 4 and the rotating rod 41, the rotating rod 41 contacts the concrete surface. Therefore, when the concrete is unevenly distributed in the mold, with one side higher than the other side, the higher side pushes the rotating rod 41 to rotate, so that the support spring 44 is compressed, so that the corresponding No. 2 pressure sensor 43 is subjected to a greater pressure than other No. 2 pressure sensors 43, thereby being able to detect whether the concrete is uneven in the mold; The present invention uses the detection ring 4 and the rotating rod 41 to hit the concrete surface, thereby pressing fillers such as stones exposed on the concrete surface under the concrete surface, so that the concrete surface is smoother after solidification. At the same time, the detection ring 4 moves up and down to prevent the detection ring 4 and the rotating rod 41 on the second block 23 from sinking into the concrete after contacting with the concrete under the action of gravity and the detection spring 28, so that the telescopic depth of the detection rod 24 changes, thereby causing inaccurate detection.

[0029] Refer to the instruction manual Figure 6 In this embodiment, a through groove 6 is formed at the lower end of the extraction tube 33; a sliding electric push rod 51 is fixedly connected to the lower end of the No. 3 block 31; an inverted 7-shaped plate 52 is hinged on the outer side of the extraction tube 33 through a torsion spring; the inverted 7-shaped plate 52 can be inserted into the through groove 6; a connecting rope 53 is fixedly connected to the sliding electric push rod 51; the other end of the connecting rope 53 is fixedly connected to the inverted 7-shaped plate 52.

[0030] In this embodiment, elastic arc-shaped pieces 54 are fixedly connected to the upper and lower sides of one end of the inverted 7-shaped plate 52 inserted into the through slot 6 .

[0031] When the movable electric push rod 32 drives the third block 31 and the extraction pipe 33 to move downward, the sliding electric push rod 51 pulls the connecting rope 53 upward, so that the connecting rope 53 pulls the inverted 7-shaped plate 52, so that the inverted 7-shaped plate 52 is pulled out from the through groove 6, so that the pipe mouth of the extraction pipe 33 is opened. When the sliding electric push rod 51 drives the third block 31 and the extraction pipe 33 to move upward and be pulled out from the concrete, the output end of the sliding electric push rod 51 moves downward again, so that the inverted 7-shaped plate 52 is reinserted into the through groove 6 under the action of the torsion spring. Therefore, the inverted 7-shaped plate 52 can open and close the extraction pipe 33 and adhere to the concrete as little as possible. The inverted 7-shaped plate 52 of the present invention is provided with an elastic arc piece 54. Therefore, when the inverted 7-shaped plate 52 is inserted into the through groove 6, the top end of the elastic arc piece 54 scrapes the through groove 6, and the concrete in the through groove 6 is pushed out of the through groove 6, thereby preventing the through groove 6 from being blocked by concrete.

[0032] Embodiment 2: A vibration method for concrete, which is applicable to the above-mentioned vibration forming table for concrete, and the steps of the method are as follows: S1. The staff uses a concrete placing machine to pour concrete into the mold. The detection rods 24 on the No. 1 block 22 and the No. 2 block 23 detect the weight of the concrete in the mold. The No. 3 block 31 and the extraction pipe 33 move downward to extract the excess concrete in the mold and replenish the missing concrete in the mold. S2, the support block 21 drives the first block 22, the second block 23, the detection rod 24 and the detection ring 4 to move up and down, and the detection ring 4 and the rotating rod 41 hit the concrete surface to press down the stones exposed on the concrete surface; S3, the vibration motor 13 drives the eccentric vibration block 14 to rotate, so that the support seat 12 and the mold vibrate.
