Description
Technical Field
[0001] The present application relates to the field of precast concrete processing, and in particular to an automatic vibration compaction system for precast concrete molds. Background Art
[0002] In tunnel projects, lining segments are permanent supporting structures. Lining segments are prefabricated concrete parts, and their quality and precision are crucial to the stability and safety of the project. The use of molds can ensure that each segment has the same shape and size to meet design requirements. At the same time, the mold can also provide the necessary support and positioning, so that the concrete can be evenly distributed and fully compacted during the pouring process, thereby improving the quality and strength of the segments.
[0003] During the segment processing, concrete needs to be added into the segment mold. During the process of adding concrete, it is usually necessary to add it into the segment mold. During the compaction process of the segment mold, a vibration device is usually used, such as a vibration table driven by a vibration motor. These vibration devices can generate the necessary vibration force to rearrange the concrete particles in the mold and tightly combine, thereby improving the density and strength of the concrete.
[0004] Some molds are equipped with pneumatic vibrators. The pneumatic vibrator uses the high-pressure gas discharged from the air compressor to connect to the product air inlet through the air pipe. When the gas pushes the piston upward, the gas in the air chamber on the piston is squeezed and discharged through the exhaust hole. When the piston reaches the end point, the gas automatically switches the ventilation direction through the groove and the airway, enters the air chamber on the piston, pushes the piston downward, and completes a cycle. This process is repeated continuously, causing the vibrator to produce translation and shaking, thereby generating vibration force. It only needs to inflate the pneumatic vibrator when adding concrete.
[0005] A concrete loading station is usually provided on a segment production line, and the segment slides to the loading station on the production line. Therefore, an air source for inflating the pneumatic vibrator is provided at the loading station. Therefore, designing a device for automatically connecting and inflating the pneumatic vibrator is an urgent problem to be solved. Summary of the invention
[0006] In order to automatically connect the inflation tube on the mobile vehicle with the air source and improve the processing efficiency, the present application provides an automatic vibration compaction system for precast concrete molds.
[0007] The present application provides a precast concrete mold automatic compaction system that adopts the following technical solutions: The cam is provided with a support frame, and the end of the support frame is abutted against the side of the support frame away from the cam, and a cavity is provided in the support frame, and a plurality of groups of pneumatic vibrators are fixedly connected in the cavity, and an inflation pipe is connected to each group of vibrators respectively. The noise reduction room is provided with an air intake pipe, and one end of the air intake pipe is connected to an external air source, and a quick docking device which automatically connects the air intake pipe and the inflation pipe is provided in the noise reduction room; the quick docking device comprises a positioning frame, and a plurality of fixed cylinders are fixedly connected in the positioning frame, and a through hole for the air intake pipe to pass through is provided on the fixed cylinder, and the air intake pipe passes through the through hole and is fixedly connected with a retaining ring, and the outer diameter of the retaining ring is larger than the inner diameter of the through hole, and an air inlet is provided on the positioning frame, and the end of the inflation port abuts against the air inlet, and a driving component which automatically drives the air intake pipe to automatically slide toward the inflation pipe until it abuts against the air inlet is connected to the fixed cylinder.
[0008] By adopting the above technical solution, when the user uses it, the driving component drives the air intake pipe to slide to the position abutting against the air inlet. After the mobile vehicle stops, the inflation pipe automatically abuts against the air inlet, and the valve of the air intake pipe is opened. The air flows through the air intake pipe and the air inlet to the inflation pipe and enters the pneumatic vibrator. The pneumatic vibrator is mainly based on the action of compressed air on the piston, which makes the piston reciprocate up and down, thereby generating vibration, preventing bubbles from appearing in the concrete during the pouring process, ensuring the density of the concrete, and thus improving the overall quality of the pipe segment. That is, the pneumatic vibrator causes the bubbles in the concrete to rise and be discharged through high-frequency vibration, making the concrete more uniform and dense, thereby realizing the automatic docking of the inflation pipe and the air intake pipe.
[0009] Optionally, the drive assembly includes a sealing ring fixedly connected to the intake pipe, the sealing ring is located in the fixed cylinder, the sealing ring and the inner wall of the fixed cylinder form a pressure chamber, the portion of the intake pipe located away from the sealing ring and the retaining ring is a telescopic tube, and a pressure tube is fixedly connected to the intake pipe, one end of the pressure tube is fixedly connected to the intake pipe, and the other end is fixedly connected to the fixed cylinder and communicated with the pressure chamber.
[0010] By adopting the above technical solution, when the user uses it, the air intake pipe is a telescopic tube. When the pressure tube guides the air in the air intake pipe into the pressure chamber, the airflow pushes the sealing ring to drive the air intake pipe to extend forward, that is, it can push the air intake pipe to move in the direction of the air inlet and plug into the air inlet, that is, open the valve on the air intake pipe, and the airflow in the air intake pipe can automatically push the air intake pipe and the inflation pipe to connect, thereby realizing air guidance.
[0011] Optionally, a return spring is provided on a portion of the air inlet pipe located near the sealing ring and the retaining ring.
[0012] By adopting the above technical solution, when the user uses it, when the air intake pipe is pushed toward the air inlet, the sealing ring squeezes the return spring. When the inflation is completed, the tension of the return spring pushes the sealing ring to move in the opposite direction, and the air in the pressure chamber is discharged. At the same time, the air intake pipe is separated from the air inlet, thereby realizing the automatic separation of the air intake pipe and the inflation pipe.
[0013] Optionally, a sealing ring arranged in a conical shape is fixedly connected to the retaining ring.
[0014] By adopting the above technical solution, when the user uses it, the sealing ring is used to snap into the air inlet to seal the inflation tube and the air inlet to reduce air leakage. When the air inlet pipe connection is subjected to pressure, the sealing ring will be further compressed, thereby enhancing the sealing effect of the sealing ring and ensuring the sealing of the connection between the air inlet pipe and the air inlet.
[0015] Optionally, a shock-absorbing plate is fixedly connected to the middle part of the mobile vehicle, a shock-absorbing cavity is formed in the shock-absorbing plate, an inflatable rubber airbag is placed in the shock-absorbing cavity, a support frame is connected to the top of the inflatable rubber airbag, an inflating tube is fixedly connected to the support frame, the inflating tube passes through the support frame and extends into the inflatable rubber airbag.

[0017] Optionally, the inflatable rubber airbag is arranged in a corrugated shape around four sides.
[0018] By adopting the above technical solution, when the user uses it, the main functions of the corrugated shape of the inflatable rubber airbag include increasing elasticity, enhancing load-bearing capacity and dispersing vibration load. The corrugated design can not only increase the elasticity of the airbag, so that it can better deform and recover when under pressure, thereby providing a better cushioning effect, but the corrugated structure can also enhance the load-bearing capacity of the airbag, making it less likely to be damaged when under heavy pressure.

[0020] By adopting the above technical solution, when the user uses it, the inflation tube is used to inflate the inflatable rubber airbag to make it expand, so that the support frame and the mobile vehicle are separated, and there is no fixation between the support frame and the mobile vehicle. The inflatable rubber airbag provides a stable elastic support force for the support frame and the pipe segment mold, effectively disperses the vibration force of the vibration platform, makes the vibration more uniform, and at the same time, reduces the transmission of vibration to the mobile vehicle, thereby reducing the collision between the mobile vehicle and the track, and reducing noise and wear.

[0026] The following is combined with Figure 1-6 This application is described in further detail.
[0027] The present application embodiment discloses a precast concrete mold automatic vibration system, referring to Figure 1 and Figure 2 , including a noise reduction room 1, a guide rail 2 and a mobile vehicle 3. The guide rail 2 passes through the noise reduction room 1. The mobile vehicle 3 is slidably connected to the guide rail 2. The mobile vehicle 3 is provided with a segment mold 4. The top of the segment mold 4 is provided with a feed port 41, and the feed port 41 is used for concrete to enter the cavity.
[0028] The noise reduction room 1 is symmetrically provided with a feed door 11 and a discharge door 12 on both sides. The feed door 11 and the discharge door 12 are provided in the direction corresponding to the guide rail 2. The figure shows that the feed door 11 and the discharge door 12 are automatic rolling doors, but they are not limited to rolling doors, and can be automatic sliding doors, automatic double doors, etc. A concrete discharge pipe 13 is provided on the top of the noise reduction room 1. The concrete discharge pipe 13 is used to automatically add concrete to the cavity of the pipe segment mold 4.
[0029] Reference Figure 3A square shock-absorbing plate 31 is fixedly connected to the middle of the mobile vehicle 3, and a shock-absorbing cavity 311 is formed in the shock-absorbing plate 31. An inflatable rubber airbag 32 is placed in the shock-absorbing cavity 311. The four sides of the inflatable rubber airbag 32 are arranged in a corrugated shape. The main functions of the corrugated shape of the inflatable rubber airbag 32 include increasing elasticity, enhancing bearing capacity and dispersing vibration load. The corrugated design can not only increase the elasticity of the airbag, but also enable it to deform and recover better when under pressure, thereby providing a better buffering effect. The corrugated structure can enhance the bearing capacity of the airbag, making it less likely to be damaged when under heavy pressure. The top of the inflatable rubber airbag 32 is fixedly connected to a support frame 33, and the inner bottom wall of the support frame 33 is fixedly connected to the inflatable rubber airbag 32. The support frame 33 is fixedly connected to the outer wall of the shock-absorbing plate 31 on all sides, and the top of the support frame 33 is fixedly connected to the support frame 34. The pipe segment mold 4 is fixedly connected to the top of the support frame 34, and the bottom of the support frame 34 is abutted against the shock-absorbing plate 31. An inflation tube 36 is fixedly connected to the support frame 34, and the inflation tube 36 passes through the support frame 34 and extends into the inflatable rubber airbag 32; the inflation tube 36 is used to inflate the inflatable rubber airbag 32 to expand it, so as to separate the support frame 34 and the moving vehicle 3, provide a stable elastic supporting force for the support frame 34 and the pipe segment mold 4, effectively disperse the vibration force of the vibration platform, make the vibration more uniform, and at the same time, reduce the transmission of vibration to the moving vehicle 3, thereby reducing the collision between the moving vehicle 3 and the track, and reducing noise and wear.
[0030] Reference Figure 3 A cavity 35 is provided in the support frame 34, and a plurality of groups of pneumatic vibrators 37 are fixedly connected in the cavity 35. In addition, the pneumatic vibrators 37 can also help concrete to better fill the corners of the mold to avoid cavities and gaps, thereby ensuring the strength and durability of the pipe segment. The figure shows that there are three groups of pneumatic vibrators 37, but it is not limited to three groups. Each group of vibrators is respectively connected to an inflation tube 36, and the inflation tube 36 is used to inflate the pneumatic vibrator 37. The pneumatic vibrator 37 is mainly based on the action of compressed air on the piston, which makes the piston reciprocate up and down, thereby generating vibration, preventing bubbles from appearing in the concrete during the pouring process, ensuring that the concrete is dense, and thus improving the overall quality of the pipe segment. That is, the pneumatic vibrator 37 causes the bubbles in the concrete to rise and be discharged through high-frequency vibration, making the concrete more uniform and dense.
[0031] Reference Figure 4The four corners of the top of the mobile vehicle 3 are fixedly connected with guide cylinders 38, and a plug-in groove 381 is provided in the guide cylinder 38. The inner wall of the plug-in groove 381 is provided with an inclined surface. The four corners of the support frame 34 are fixedly connected with guide columns 39, and the ends of the guide columns 39 are provided with inclined surfaces, and the ends of the guide columns 39 are plugged into the guide cylinders 38; when the support frame 34 vibrates under the action of the pneumatic vibrator 37, the guide column 39 slides vertically in the guide cylinder 38, and the inclined surface at the end of the guide column 39 cooperates with the inner wall of the plug-in groove 381, which can make the vibration of the support frame 34 more stable.
[0032] Reference Figure 5 and Figure 6 In order to improve the processing efficiency, an air source is arranged at the position of the noise reduction room 1, and the air source is used to inflate the pneumatic vibrator 37 and the inflatable rubber airbag 32. A plurality of air inlet pipes 14 are fixedly connected to the noise reduction room 1, and four are shown in the figure, but are not limited to four. The number is determined according to the number of pneumatic vibrators 37 arranged. The four air inlet pipes 14 are used to correspond to the pneumatic vibrators 37 and the inflatable rubber airbag 32 in a one-to-one manner. One end of the air inlet pipe 14 extends out of the noise reduction room 1 and is connected to the air source, and the other end is used to be connected to the inflatable pipe 36. A quick docking device 5 is arranged on the noise reduction room 1, and the quick docking device 5 is used to quickly connect the air inlet pipe 14 and the inflatable pipe 36.
[0033] The quick docking device 5 includes a positioning frame 51, in which a limiting plate 52 is fixedly connected, and a plurality of fixed cylinders 53 are fixedly connected to the limiting plate 52. Four fixed cylinders 53 are shown in the figure. The structure of each fixed cylinder 53 is the same. Only one of the fixed cylinders 53 is taken as an example here. A through hole 531 for the air intake pipe 14 to pass through is opened on the limiting plate 52 and the fixed cylinder 53. The air intake pipe 14 passes through the through hole 531 and is fixedly connected with a retaining ring 54. The outer diameter of the retaining ring 54 is larger than the inner diameter of the through hole 531. The retaining ring 54 is used to prevent the air intake pipe 14 from detaching from the fixed cylinder 53.
[0034] Among them, the intake pipe 14 is located in the fixed cylinder 53 and is fixedly connected with a sealing ring 55. The sealing ring 55 is supported on the inner wall of the fixed cylinder 53 and can slide in the fixed cylinder 53. The sealing ring 55 and the inner wall of the fixed cylinder 53 form a pressure chamber 551. The portion of the intake pipe 14 located at the sealing ring 55 away from the baffle ring 54 is a telescopic tube. The portion of the intake pipe 14 located at the sealing ring 55 close to the baffle ring 54 is sleeved with a return spring 56. A pressure pipe 57 is fixedly connected to the intake pipe 14. One end of the pressure pipe 57 is fixedly connected to the intake pipe 14, and the other end is fixedly connected to the fixed cylinder 53 and communicated with the pressure chamber 551. The pressure pipe 57 can transfer the intake pipe 14 to the pressure chamber 551. The air in the air pipe 14 is introduced into the pressure chamber 551, thereby pushing the sealing ring 55 to drive the intake pipe 14 to extend forward; one end of the inflation pipe 36 extends out of the support frame 34, and the positioning frame 51 is provided with an air inlet 511 at a position corresponding to the inflation pipe 36. A conical sealing ring 541 is fixedly connected to the retaining ring 54, and the sealing ring 541 is used to be snapped into the air inlet 511 to seal the inflation pipe 36 and the air inlet 511 to reduce air leakage. When the connection between the intake pipe 14 is subjected to pressure, the sealing ring 541 will be further compressed, thereby enhancing the sealing effect of the sealing ring 541 and ensuring the sealing of the connection between the intake pipe 14 and the air inlet 511.
[0035] After the valve on the intake pipe 14 is opened, the air in the intake pipe 14 enters the pressure pipe 57, and the pressure pipe 57 pushes the sealing ring 55 to slide in the fixed tube 53, thereby pushing the intake pipe 14 to expand and contract in the direction of the air inlet 511, so that the sealing ring 541 is inserted into the air inlet 511, and the inflation pipe 36 and the air inlet 511 are sealed to reduce air leakage. When the connection of the intake pipe 14 is subjected to pressure, the sealing ring 541 will be further compressed, thereby enhancing the sealing effect of the sealing ring 541 and ensuring the sealing of the connection between the intake pipe 14 and the air inlet 511. At the same time, the sealing ring 55 compresses the return spring 56. After closing the valve on the intake pipe 14, the tension of the return spring 56 causes the return spring 56 to relax, pushing the sealing ring 55 to slide in the opposite direction, and the air in the pressure chamber 551 is discharged into the intake pipe 14, and at the same time, the intake pipe 14 and the air inlet 511 are automatically separated, completing the rapid docking and separation of the intake pipe 14 and the inflation pipe 36.
[0036] The implementation principle of the automatic compaction system for precast concrete molds in the embodiment of the present application is as follows: when the segment mold 4 and the mobile vehicle 3 slide into the noise reduction room 1, the concrete discharge pipe 13 on the top of the noise reduction room 1 automatically adds concrete to the cavity of the segment mold 4; at the same time, the valve on the air intake pipe 14 is opened, and the air in the air intake pipe 14 enters the pressure pipe 57. The pressure pipe 57 pushes the sealing ring 55 to slide in the fixed tube 53. The sealing ring 55 compresses the reset spring 56 and pushes the air intake pipe 14 to expand and contract in the direction of the air inlet 511, so that the sealing ring 541 is inserted into the air inlet 511, so that the air intake pipe 14 and the inflation pipe 36 are connected. When the connection of the air intake pipe 14 is subjected to pressure, the sealing ring 541 will be further compressed, thereby enhancing the sealing effect of the sealing ring 541.
[0037] After the air inlet pipe 14 and the inflation pipe 36 are connected, the inflation pipe 36 inflates air into the pneumatic vibrator 37. The pneumatic vibrator 37 is mainly based on the action of compressed air on the piston, causing the piston to reciprocate up and down, thereby generating vibration. The pneumatic vibrator 37 causes the bubbles in the concrete to rise and be discharged through high-frequency vibration, thereby preventing bubbles from appearing in the concrete during the pouring process, ensuring that the concrete is dense, and thus improving the overall quality of the pipe segment.
[0038] At the same time, the compressed air in each air inlet pipe 14 enters the pneumatic vibrator 37 and the inflatable rubber airbag 32 respectively. The inflation pipe 36 introduces the compressed air into the inflatable rubber airbag 32 to inflate it, thereby separating the support frame 34 and the moving vehicle 3, providing a stable elastic support force for the support frame 34 and the segment mold 4, effectively dispersing the vibration force of the segment mold 4, making the vibration more uniform, and at the same time, reducing the transmission of vibration to the moving vehicle 3, thereby reducing the collision between the moving vehicle 3 and the track, and reducing noise and wear.
[0039] After the loading and compaction are completed, after the valve on the intake pipe 14 is closed, the tension of the return spring 56 causes the return spring 56 to relax, pushing the sealing ring 55 to slide in the opposite direction, and leading the air in the pressure chamber 551 into the intake pipe 14, while driving the intake pipe 14 to automatically separate from the air inlet 511, completing the rapid docking and separation of the intake pipe 14 and the inflation pipe 36.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
