Description

Technical Field

[0001] The present invention relates to the technical field of small precast component production, and particularly relates to a mobile vibration device, a concrete vibration system and a production method. Background Art

[0002] In the field of railway bridges, to ensure the safety of high-speed train operation, it is required that the parapets suspended on both sides of the bridge have good quality. When pouring the parapet concrete, vibration must be carried out to remove the air bubbles therein, make the concrete densely combined, eliminate phenomena such as honeycombing and pitting on the concrete surface, so as to improve its strength and ensure the quality of the concrete components.

[0003] To achieve flexible large-scale production of small batches of parapets, at present, fixed vibration tables are usually used for concrete vibration of parapets. When using a fixed vibration table to vibrate the parapet concrete, the vibration platform is fixedly installed at a specific station on the production line (such as the pouring area). By rigidly fixing the assembled parapet mold on the surface of the vibration platform and using bolts or hydraulic clamps to ensure that the mold (or pedestal) vibrates synchronously with the vibration table, energy loss is avoided; this vibration method has high efficiency and good quality consistency. However, after the vibration operation of the current batch of parapet concrete is completed, special equipment (forklifts commonly used in small-batch production) is required to transfer the mold (including the vibrated concrete), the equipment usage cost is high, and due to the need to ensure stability (prevent cracking) before the concrete initial setting, the quality control risk during the transfer process is large. Therefore, it is considered to design a mobile vibration device that can shuttle under each parapet mold for vibration operation, reduce the transfer link, and ensure the vibration effect at the same time. Summary of the Invention

[0004] The purpose of the present invention is to provide a mobile vibration device, a concrete vibration system and a production method for the problem of high equipment usage cost and large transfer risk existing in the transfer of the parapet mold when using a fixed vibration table for parapet concrete vibration in the prior art, which can reduce the transfer link of the parapet mold and reduce equipment investment while taking into account the vibration effect and vibration efficiency.

[0005] In a first aspect, the present invention provides a mobile vibration device, including: A vibrating trolley, on which a jacking mechanism and a vibration platform are provided. The vibration platform is used to contact the bottom surface of the parapet model pedestal. The jacking mechanism can drive the vibration platform to lift and lower. The vibration platform and the jacking mechanism can move relative to each other. The vibration platform is provided with surface vibrators and electromagnetic chucks; A control system, which is connected to the vibrating trolley, the jacking mechanism, the surface vibrators and the electromagnetic chucks.

[0006] In this solution, by setting a jacking mechanism and a vibrating platform on the vibrating trolley, the vibrating trolley can be driven by the control system to drive the jacking mechanism and the vibrating platform to move together, and the jacking mechanism can be driven to drive the vibrating platform to move up and down. When the vibrating platform rises to contact the bottom surface of the shutter model pedestal, the electro-permanent magnetic chuck can be driven by the control system to magnetize, so that the electro-permanent magnetic chuck is adsorbed and connected to the shutter model pedestal, thereby realizing the fixation of the vibrating platform and the shutter model pedestal, facilitating the separation of the jacking mechanism and the vibrating platform and then enabling the vibration operation to be carried out by the attached vibrator.

[0007] By using the above-mentioned mobile vibration device, the shutter molds at different workstations can be vibrated in-situ, reducing the transfer link of the shutter molds during the vibration stage, with high production efficiency, low interference risk, facilitating the guarantee of the quality of the shutter concrete production, and reducing the investment in the cost of transfer equipment, resulting in better economic benefits.

[0008] In addition, compared with the method of vibrating in-situ by separately setting attached vibrators for multiple shutter molds, using the above-mentioned mobile vibration device can reduce a large amount of cable line layout and the use investment of attached vibrators, with flexible use, cost savings, and efficiency improvement. For example, when there are twenty shutter molds for shutter concrete production, each shutter mold needs to be equipped with two attached vibrators to ensure the vibration quality for discharging air bubbles. If two attached vibrators are configured for each of the twenty shutter molds, a total of forty attached vibrators are required, and the attachment vibrator positions need to be arranged for each shutter mold separately, resulting in a large amount of manual input, long layout time, and extremely high equipment investment cost; if two attached vibrators are used to vibrate each shutter mold in turn, although the equipment investment cost can be effectively controlled, the vibration efficiency is greatly reduced, and the attached vibrator and the shutter mold need to be installed and disassembled each time for vibration, resulting in a large amount of manual input; if the above-mentioned mobile vibration device is used to automatically circulate and vibrate multiple shutter molds, not only can the vibration quality be guaranteed, but also the vibration efficiency can be taken into account, liberating the labor force and saving the total cost of equipment and manpower.

[0009] Preferably, a guiding structure is provided at the bottom of the vibrating platform, and the guiding structure is in sliding fit with the jacking mechanism. The guiding structure can achieve better positioning of the separable vibrating platform during the moving process and the vibration process, ensuring the relative stability of the position between the vibrating platform and the jacking mechanism.

[0010] Preferably, the guiding structure is a tapered sleeve, and a tapered head is provided at the top of the jacking mechanism. The tapered head is adapted to the shape of the tapered sleeve, with good working condition adaptability.

[0011] Preferably, the jacking mechanism adopts a hydraulic cylinder.

[0012] Preferably, a position sensor is provided on the side of the vibrating trolley, and the position sensor is connected to the control system. The position sensor is used to detect the position of the vibrating trolley in real time, so as to facilitate the automatic control of the vibrating trolley and automatically perform the next cycle of vibrating function.

[0013] Preferably, the above-mentioned vibrating trolley includes a cable reel, and the cable reel is used for winding wire to supply power to the vibrating trolley.

[0014] In a second aspect, the present invention provides a concrete vibrating system, including at least one production line. Along the production line, there is a track for the above-mentioned any kind of concrete vibrating device to move, and several groups of formwork bases are arranged at intervals along the production line. Each group of formwork bases is arranged on opposite sides of the track, and the formwork bases are used to support the shutter model pedestal.

[0015] By adopting the above-mentioned concrete vibrating system, by arranging the production line in columns, arranging several groups of formwork bases for supporting the shutter model pedestal at intervals along the production line, and setting a track for the above-mentioned concrete vibrating device to move on the production line, the above-mentioned concrete vibrating device can perform cyclic vibration along the production line, reducing manual participation and transfer links, and improving production efficiency.

[0016] Preferably, an elastic member is provided on the top of the formwork base to better adapt to the vibration of the shutter model pedestal, so that the vibrating effect is better.

[0017] In a third aspect, the present invention provides a method for producing concrete shutters, adopting any of the above-mentioned concrete vibrating systems, including the following steps: S1: Drive the vibrating trolley to move along the track to the position below the shutter model pedestal at the designated work station; S2: Drive the lifting mechanism to lift the vibrating platform until it fits against the bottom surface of the shutter model pedestal, and control the electro-permanent magnetic chuck to magnetize, so that the vibrating platform adsorbs and connects the shutter model pedestal through the electro-permanent magnetic chuck; S3: Drive the lifting mechanism to retract, separate the lifting mechanism from the vibrating platform, drive the attached vibrator to vibrate, and drive the shutter model pedestal and the concrete to perform vibrating operations; S4: Drive the lifting mechanism to rise again, control the electro-permanent magnetic chuck to demagnetize, and make the vibrating platform descend to the designated position with the lifting mechanism; S5: When the vibrating platform descends in place, send a control signal to the vibrating trolley through the control system, and the vibrating trolley automatically moves to the next work station according to the control signal.

[0018] The present invention uses the above concrete vibration system for the production of shutter concrete, which can integrate automatic traveling, automatic lifting, automatic suction, and automatic vibration.

[0028] Embodiment 1 A mobile vibration device, as Figures 1-3 shown, includes a vibrating trolley and a control system 12. The vibrating trolley includes a traveling chassis 1, traveling wheels, a driving mechanism 3, a lifting mechanism 4, a vibration platform 5, and a cable reel 8. The traveling chassis 1 is the main support frame of the vibrating trolley, with four traveling wheels and a driving mechanism 3 provided at the bottom. The four traveling wheels are arranged at rectangular positions; the two front traveling wheels are used as driving wheels and are coaxially driven by the driving mechanism 3. The driving mechanism 3 is electrically connected or communicatively connected to the control system 12. The two rear traveling wheels are used as driven wheels, and the driving mechanism 3 provides power for the vibrating trolley; the driving mechanism 3 preferably uses a variable-frequency braking motor and can automatically brake after traveling in place. The lifting mechanism 4 is fixedly connected to the traveling chassis 1 through components such as an L-shaped support. The lifting mechanism 4 makes a linear reciprocating motion and is controlled by the control system 12. In this embodiment, the lifting mechanism 4 preferably uses a hydraulic cylinder. The hydraulic cylinder is connected to a hydraulic pump station, and the hydraulic pump station is fixedly connected to the traveling chassis 1. The hydraulic cylinders are distributed at the four corners of the traveling chassis 1, close to the traveling wheels, with simple structure, reliable operation, and stable movement. The piston end of the hydraulic cylinder is arranged upward, and the top is set as a conical head. Correspondingly, a conical sleeve matching the conical head of the hydraulic cylinder is provided at the bottom of the vibration platform 5 for guiding, ensuring the relative relationship between the traveling chassis 1 and the vibration platform 5, and having good working condition adaptability.

[0029] As other implementable ways, the conical sleeve can also be replaced with other guiding structures such as a pyramid sleeve, a sleeve, etc. Correspondingly, the lifting mechanism 4 and the guiding structure should be adapted and can slide up and down in cooperation.

[0030] The vibration platform 5 is connected with an attached vibrator 6 and an electro-permanent magnetic chuck 7. The attached vibrator 6 and the electro-permanent magnetic chuck 7 are both electrically connected to the control system 12. By controlling the control system 12 to magnetize or demagnetize the electro-permanent magnetic chuck 7, the vibration platform 5 is adsorbed on the bottom of the shutter model pedestal 13 or separated; the attached vibrator 6 is fixedly installed at the bottom of the vibration platform 5 and is symmetrically arranged along the longitudinal axis; the electro-permanent magnetic chucks 7 are distributed at four rectangular positions and are embeddedly connected to the vibration platform 5.

[0031] Furthermore, a position sensor is provided on the side of the traveling chassis 1, and the position sensor is communicatively connected to the control system 12. The position sensor is used to detect the position of the vibrating trolley in real time and transmit the position of the vibrating trolley to the control system 12 to control the precise positioning of the vibrating trolley, so as to facilitate the automatic control of the vibrating trolley and automatically perform the next cycle of vibrating function.

[0032] The control system 12 and the cable reel 8 are respectively arranged on the front and rear sides of the traveling chassis 1. The cable reel 8 is used to wind the power cord to facilitate the supply of power to the vibrating trolley.

[0033] In the initial state, the vibration platform 5 is supported on the upper surface of the traveling chassis 1, and the lifting mechanism 4 and the vibration platform 5 are positioned through the guiding structure. The control system 12 drives the vibrating trolley to move directly below the shutter model pedestal 13, and then drives the lifting mechanism 4 to lift the vibration platform 5 until it fits against the bottom surface of the shutter model pedestal 13; since the end of the hydraulic cylinder is a conical head, it can ensure that the vibration platform 5 is accurately positioned during the ascending or descending process with small deviation. When the vibration platform 5 fits against the shutter model pedestal 13, the control system 12 controls the electro-permanent magnetic chuck 7 to adsorb the vibration platform 5 to the bottom of the shutter model pedestal 13, and at the same time the hydraulic cylinder retracts to separate the traveling chassis 1 from the vibration platform 5. After the hydraulic cylinder retracts, it can always maintain a sleeved state with the guiding structure at the bottom of the vibration platform 5 to ensure the relative position relationship between the traveling chassis 1 and the vibration platform 5. By starting the attached vibrator 6, the shutter model pedestal 13 and the concrete are driven to produce a high-frequency vibration effect, which helps to compact and form the shutter concrete, improving the construction efficiency and project quality.

[0034] After the vibration is completed, the lifting mechanism 4 rises to the in-place position, the electro-permanent magnetic chuck 7 demagnetizes, and the vibration platform 5 descends with the lifting oil cylinder back onto the traveling chassis 1, waiting for the control signal from the control system 12 and moving to the next working station automatically to start a new vibration work cycle.

[0035] Among them, the shutter model pedestal 13 is a dedicated production mold or support platform in the prior art for precast concrete shutters (such as sound barriers, track 9 shutters, cable trench covers, etc.), mainly used for standardizing and mass-producing concrete shutters to ensure accurate product dimensions, smooth surfaces, and improve production efficiency.

[0036] Using the above-mentioned mobile vibration device can perform in-situ vibration on the shutter molds (i.e., the shutter model pedestal 13) at different working stations, reducing the transfer link of the shutter molds during the vibration stage, having high production efficiency, low interference risk, being conducive to ensuring the production quality of the shutter concrete, and reducing the investment in the cost of transfer equipment, with good economic benefits. The vibration device has a high degree of mechanization and intelligence, integrating automatic traveling, automatic lifting, automatic suction, and automatic vibration, without manual intervention, reducing the influence of human subjective factors.

[0037] Example 2 Based on Example 1, this example provides a concrete vibration system, as Figures 4-8 shown, including at least one production line. Along the production line, there is a track 9 for the above-mentioned concrete vibration device to move. Along the production line, several groups of formwork bases 10 are arranged at intervals. Each group of formwork bases 10 is arranged on opposite sides of the track 9. The formwork base 10 is used to support the shutter model pedestal 13. In this example, the formwork base 10 is composed of 2 concrete strip footings, with dimensions of 1060mm×150mm×420mm and a center distance of 1800mm. The track 9 is arranged inside the formwork base 10 and is composed of two 10# I-beams with a center distance of 1330mm. It is fixed to the ground by buckle plates.

[0038] Furthermore, in this example, as Figure 4 、 Figure 5 shown, elastic members 11 are symmetrically arranged at the top of each side of the formwork base 10 to better adapt to the vibration of the shutter model pedestal 13, so that the vibration effect is better. The elastic member 11 is preferably a vibration spring. The vibration spring is connected to the shutter model pedestal 13 and plays a role in transmission, shock absorption and buffering. It can not only reduce the loss of vibration energy, but also greatly reduce the possibility of damage to the shutter model pedestal 13. Further, a small section of steel pipe sleeve is integrally connected to the top and bottom of the outer periphery of the vibration spring respectively. The middle part of the vibration spring is reserved as a buffer deformation section. The two sleeves are respectively fixed to the surface of the formwork base 10 and the bottom surface of the shutter model pedestal 13, and are used as the lower sleeve and the upper sleeve respectively. Among them, the upper sleeve (i.e., the sleeve located at the top of the vibration spring) is detachably connected to the shutter model pedestal 13 by bolts, so as to facilitate the installation and removal of the shutter model pedestal 13 and the formwork base 10. The inner diameters of the two steel pipe sleeves are about 2mm larger than the outer diameter of the vibration spring, which can play a role in protecting and limiting the vibration spring. The vibration spring should have a relatively large axial stiffness to better support the shutter model pedestal 13. At the same time, the vibration spring can also play a role in limiting the shutter model pedestal 13 in the horizontal direction. In this example, the formwork bases 10 can be arranged at intervals of 1900mm along the length direction of the factory building, which is convenient for the opening and closing of the shutter model pedestal 13.

[0039] By setting springs on the formwork base 10, the elasticity of the shutter model pedestal 13 is increased, the vibration effect is better, the shutter concrete is dense, the surface finish is high, and the appearance quality of the shutter concrete is improved.

[0040] Furthermore, as Figure 8As shown in the figure, the above concrete vibrating system includes a reserved area for the production of railing covers, an automatic steel bar welding area, a steel reinforcement cage storage area, and a precast slab area. It is preferred to set at least two precast concrete production lines for the slab in the precast slab area to ensure production efficiency. The reserved area for the production of railing covers, the automatic steel bar welding area, and the steel reinforcement cage storage area are arranged in sequence, and the reserved area for the production of railing covers, the automatic steel bar welding area, and the steel reinforcement cage storage area are all arranged in parallel with the precast slab area. By reasonably arranging the functional areas of the factory area, the precast concrete production line for the slab is carried out, which is conducive to ensuring production efficiency.

[0041] In the above concrete vibrating system, by arranging the production lines in columns, several groups of formwork bases 10 for supporting the slab model pedestal 13 are arranged at intervals along the production line, and a track 9 for the above concrete vibrating device to move is arranged on the production line, so that the above concrete vibrating device can perform cyclic vibration along the production line, reducing manual participation and transfer links, and improving production efficiency.

[0042] Embodiment 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a method for producing concrete slabs, using the above concrete vibrating system, including the following steps: S1: According to the position detection signal, the control system drives the vibrating trolley to move along the track 9 to the lower part of the slab model pedestal 13 at the specified working position; S2: When the vibrating trolley moves into place, drive the jacking mechanism 4 to lift the vibration platform 5 until it fits against the bottom surface of the slab model pedestal 13; by controlling the energization of the electro-permanent magnetic chuck 7, the vibration platform 5 is adsorbed and connected to the slab model pedestal 13 through the electro-permanent magnetic chuck 7, and the jacking mechanism 4 and the vibration platform 5 can be separated; S3: Drive the jacking mechanism 4 to retract, and the jacking mechanism 4 is separated from the vibration platform 5, so that the vibration is only transmitted to the slab model pedestal 13; drive the attached vibrator 6 to vibrate, driving the slab model pedestal 13 and the concrete to perform vibration operations; S4: After the vibration operation is completed, drive the jacking mechanism 4 to rise again until the jacking mechanism 4 makes positioning contact with the vibration platform 5. At this time, control the electro-permanent magnetic chuck 7 to demagnetize, so that the vibration platform 5 and the slab model pedestal 13 are in a separable state; drive the jacking mechanism 4 to descend, and the vibration platform is separated from the slab model pedestal 13, so that the vibration platform 5 descends with the jacking mechanism 4 and returns to the traveling chassis 1 to resume its original state; S5: When the vibration platform 5 descends into place, send a control signal to the vibrating trolley through the control system 12, and the vibrating trolley transfers to the next working position according to the control signal.

[0043] The present invention uses the above concrete vibration system for the production of shutter concrete, which can integrate automatic traveling, automatic lifting, automatic suction, and automatic vibration. It does not require manual intervention, reduces the influence of human subjective factors, has a high degree of mechanization and intelligence, is conducive to improving production efficiency, and ensures production quality.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
