Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated bridge slab production, in particular to a prefabricated bridge slab production device and a use method thereof. BACKGROUND

[0002] In the industrialized production of prefabricated bridge slabs (such as simple-supported beams, hollow slabs, box girders, etc.), the vibration produced by the insertion-type vibrator after the concrete enters the mold is the key link to ensure the compactness, strength and durability of the concrete structure. The vibration and compaction after the concrete is poured is the key process to ensure the mechanical properties of the component. The insertion-type vibrator liquefies the concrete through high-frequency vibration, thereby expelling air bubbles, filling the gaps between the steel bars, and avoiding defects such as honeycombs and pitted surfaces. However, as a load-bearing structure, the prefabricated bridge slab usually has a steel bar framework inside. The steel bar framework is a three-dimensional framework formed by steel bars according to design requirements, and is the "skeleton" and core load-bearing system of the concrete structure. The steel bar framework can bear the load in the tensile region of the structure through cooperative work with the concrete, thereby avoiding cracking or damage of the concrete due to tension.

[0003] The current prefabricated bridge slab production device and use method are prone to frequent contact with the steel bars during the movement or insertion of the vibrator. Although the steel bar framework is fixed by binding or spot welding, the high-frequency vibration impact force and direct collision of the vibrator can cause plastic deformation of the local steel bars, damage the original design load path, and when the vibrator is blocked by the steel bars, it needs to be stopped to adjust the insertion angle, pulled out and reinserted, or the vibration point is replaced. This process can cause the interruption of local vibration of the concrete, easily causing missed vibration, air bubble aggregation or aggregate emptying, reducing the compactness of the concrete, and reducing the production quality of the prefabricated bridge slab.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] In order to solve the technical problem that the first vibrator 8 is easy to collide with the steel bar, resulting in plastic deformation of the local steel bar and steel bar blockage, and the machine needs to be stopped to adjust the insertion angle, pull out and reinsert, or replace the vibration point, as shown in Figures 1-8 The following preferred technical solutions are provided: As shown in Figure 1As shown, a production device for prefabricated bridge panels includes a driving frame 1, which can provide a driving force to drive subsequent structures to move back and forth. A mold 2 is fixedly installed inside the driving frame 1, and a steel skeleton is inside the mold 2. By introducing concrete into the mold 2, the steel skeleton forms a "circumferential constraint" on the core area concrete, which can prevent the concrete from expanding laterally when under pressure, thereby improving its compressive strength and ductile deformation capacity. A swinging member 3 is fixedly installed on one side of the driving frame 1, and a pushing member 4 is slidingly connected to the side of the driving frame 1 close to the swinging member 3, and one end of the pushing member 4 is slidingly connected to the swinging member 3. When the driving frame 1 causes the pushing member 4 to move back and forth, the swinging member 3 causes the pushing member 4 to swing slightly during the movement. The small-amplitude swing is an efficient and safe vibration optimization method, which expands the coverage range and improves the bubble discharge efficiency through path optimization, while reducing the negative impact on the steel bars and concrete structure.

[0025] Several frames 5 are provided at the bottom of the pushing member 4, and the pushing member 4 can push several frames 5 to rotate at the same time. A lifting member 6 is fixedly installed on one side of the pushing member 4, and a first moving seat 7 is slidably connected to one side of the frame 5, and the first moving seat 7 is rotatably connected to the lifting member 6. A first vibrator 8 is installed at one end of the first moving seat 7, and the concrete can be vibrated by the first vibrator 8. The high-frequency vibration will cause the concrete particles to produce inertial displacement. The bubbles will rise along the gap between the aggregates after being squeezed by the vibration and eventually escape from the surface, thereby making the concrete surface smooth and flat, reducing the cost of later repairs, promoting concrete density, improving structural strength, ensuring concrete homogeneity, preventing segregation, and enhancing the bonding force between concrete and steel bars. The first vibrator 8 is powered by a wireless battery, and the vibration structure is inside the vibrating rod, without the need for an external power cable.

[0026] The second movable seat 9 is slidably connected to the other side of the frame 5. The installation position of the second movable seat 9 is higher than the first movable seat 7, and the first movable seat 7 is transmission-connected to the second movable seat 9. A second vibrator 10 is installed at one end of the second movable seat 9. The second vibrator 10 has the same structure as the first vibrator 8. The low-position first vibrator 8 vibrates the deep bottom and middle of the concrete, which can eliminate deep bubbles and discharge moisture, ensuring that the core area of ​​the structure is dense. The high-position second vibrator 10 moves ahead and acts on the shallow layer, which can timely process the surface and near-surface concrete, and make up for the problem of insufficient coverage of the shallow layer by the low-position vibrator. Therefore, the full-depth vibration coverage of the deep and shallow layers is formed by the cooperation of the two. Especially in areas with dense steel bars, the local leakage vibration caused by the obstruction of steel bars can be reduced by high and low position division of labor. Two relative ultrasonic sensors 20 are obliquely installed on one side of the frame 5. The ultrasonic sensors 20 are electrically connected to the pusher 4 and the lifting member 6 through the controller.

[0027] In the initial state, the low first vibrator 8 and the high second vibrator 10 can vibrate the concrete, and the driving frame 1 can drive the pusher 4 to move, so that the first vibrator 8 and the second vibrator 10 can be slowly moved, when the low first vibrator 8 is close to the steel bar, the ultrasonic sensor 20 detects the steel bar in the moving direction, at this time, the controller (the controller is prior art, not shown in the figure) drives the lifting piece 6 to drive the first moving seat 7 to move upwards, so that the first vibrator 8 moves upwards, because the first moving seat 7 is in transmission connection with the second moving seat 9, when the first moving seat 7 moves upwards, the high second moving seat 9 moves downwards, because there is a gap between the first vibrator 8 and the second vibrator 10, at this time, the second vibrator 10 has inserted into the concrete by passing the steel bar, and the first vibrator 8 moves to the surface area of the concrete by following the first moving seat 7, at the same time, the four frames 5 are rotated by the pusher 4, so that the first vibrator 8 and the second vibrator 10 are rotated, and the roles of the first vibrator 8 and the second vibrator 10 are interchanged.

[0028] The main and secondary vibration areas can be flexibly switched according to the distribution of the steel bar, and the deformation of the steel bar or the damage of the vibrator caused by hard collision is avoided, in the traditional vibration operation, the vibrator needs to be frequently stopped and restarted when encountering the steel bar, and the position needs to be manually adjusted after stopping and then reinserted, so that the high energy consumption cycle of starting and stopping is repeatedly experienced, the ultrasonic sensor 20 is used to predict and the first vibrator 8 and the second vibrator 10 are alternately used, so that the continuous operation mode of not stopping when encountering the steel bar and only switching the working part is realized, when the first vibrator 8 moves upwards to avoid, the second vibrator 10 has been started to vibrate synchronously, the instantaneous high energy consumption of the single device is avoided, and the energy-saving effect can be achieved.

[0029] In the initial state, the low first vibrator 8 and the high second vibrator 10 can vibrate the concrete, and the driving frame 1 can drive the pusher 4 to move, so that the first vibrator 8 and the second vibrator 10 can be slowly moved, when the low first vibrator 8 is close to the steel bar, the ultrasonic sensor 20 detects the steel bar in the moving direction, at this time, the controller (the controller is prior art, not shown in the figure) drives the lifting piece 6 to drive the first moving seat 7 to move upwards, so that the first vibrator 8 moves upwards, because the first moving seat 7 is in transmission connection with the second moving seat 9, when the first moving seat 7 moves upwards, the high second moving seat 9 moves downwards, because there is a gap between the first vibrator 8 and the second vibrator 10, at this time, the second vibrator 10 has inserted into the concrete by passing the steel bar, and the first vibrator 8 moves to the surface area of the concrete by following the first moving seat 7, at the same time, the four frames 5 are rotated by the pusher 4, so that the first vibrator 8 and the second vibrator 10 are rotated, and the roles of the first vibrator 8 and the second vibrator 10 are interchanged.

[0030] And through the swing piece 3, the push piece 4 is slowly moved to produce a small amplitude swing, the slow movement ensures that the first vibrator 8 and the second vibrator 10 have sufficient action time in each area, and the small amplitude swing allows the vibration energy to gradually diffuse to the periphery, and the vibration is gradually transmitted from the center of the first vibrator 8 and the second vibrator 10 to the edge, avoiding the one-sweep caused by the rapid movement, which leads to uneven vibration, and fully improves the vibration effect of the concrete, so as to realize the continuous action of the position switching (the first vibrator 8 rises, and the second vibrator 10 inserts) of the first vibrator 8 and the second vibrator 10, avoids the damage or jam caused by the direct contact of the first vibrator 8 or the second vibrator 10 with the steel bar, and realizes the position exchange of the first vibrator 8 or the second vibrator 10 through the push piece 4, ensures that the switching logic can be repeated next time when the steel bar is encountered, and completely solves the problem that the traditional vibrator is forced to stop due to the blocking of the steel bar.

[0031] As shown in Figure 2 The driving frame 1 includes a base 11 and a first support 12 fixed on one side of the base 11, which can ensure that the first support 12 is stable on the base 11 through a welding connection mode. The first support 12 is fixedly installed with a motor 13 at one end. The first support 12 is rotatably connected with a screw rod 14 inside, and the screw rod 14 is fixedly connected with the output end of the motor 13. The base 11 is fixedly installed with a second support 15 on one side. The second support 15 is fixedly installed with a sliding rod 16 inside. The surface of the screw rod 14 is threadedly connected with a moving plate 17, and the moving plate 17 is slidably connected with the first support 12, the second support 15 and the sliding rod 16. The motor 13 can drive the screw rod 14 to rotate, and the screw rod 14 can drive the moving plate 17 to move, so as to drive the push piece 4 to reciprocate. The limiting of the sliding rod 16 can prevent the moving plate 17 from rotating with the screw rod 14, so as to ensure that the moving plate 17 can continuously and stably move.

[0032] As shown in Figure 3 and Figures 6-8 One end of the frame 5 is fixedly installed with a shaft rod 51, which is rotatably connected with the bottom plate 41. The first gear 52 is fixedly installed at one end of the shaft rod 51, and the first tooth plate 45 is meshingly connected with the first gear 52. The frame 5 is internally provided with a sliding groove 53 on both sides. The frame 5 is rotatably connected with a supporting rod 54 inside. The second gear 55 is fixedly installed on the surface of the supporting rod 54. The output end of the electric push rod 43 can drive the first tooth plate 45 to move. Since the first tooth plate 45 is meshingly connected with the first gear 52, the movement of the first tooth plate 45 can drive the first gear 52 to rotate, until the frame 5 rotates 360° to exchange the positions of the first vibrator 8 and the second vibrator 10.

[0033] The lifting member 6 includes a cylinder 61 and a ring frame 62 fixed at one end of the cylinder 61. The ring frame 62 is composed of four circular rings. The output end of the cylinder 61 is connected to one side of the rectangular plate 413. Two contact rods 63 are fixedly installed on one side of the ring frame 62, and the two contact rods 63 are slidably connected to the two strip plates 414. An arc groove 64 is opened inside the ring frame 62. The ring frame 62 can be moved through the output end of the cylinder 61, so that the height of the ring frame 62 can be adjusted.

[0034] The first movable seat 7 includes an L-shaped plate 71 and a second tooth plate 72 fixed on one side of the L-shaped plate 71. The L-shaped plate 71 is slidably connected to the frame 5, and the second tooth plate 72 is meshed with the second gear 55. First limit blocks 73 are fixedly installed on both sides of the L-shaped plate 71, and the two first limit blocks 73 are slidably connected to the slide groove 53. The two first limit blocks 73 cooperate with the slide groove 53 to limit the movement of the L-shaped plate 71 and prevent the L-shaped plate 71 from separating from the frame 5. A first damper 74 is fixedly installed at one end of the L-shaped plate 71, and the first vibrator 8 is fixedly connected to the first damper 74. The first damper 74 attenuates the vibration amplitude transmitted by the first vibrator 8 through damping materials such as silicone and metal damping plates to avoid damage to the connection structure due to vibration or affecting the stability of the equipment. A T-shaped rod 75 is fixedly installed at the other end of the L-shaped plate 71, and the T-shaped rod 75 is slidably connected to the arc groove 64.

[0035] When the output end of the cylinder 61 drives the annular frame 62 to move upward, the L-shaped plate 71 can be driven to move through the connection of the T-rod 75, thereby driving the first vibrator 8 to move upward. When the frame 5 rotates, the T-rod 75 can be driven to move inside the arc groove 64, so that the T-rod 75 rotates around the shaft 51. On the one hand, four first vibrators 8 can be driven to move by one cylinder 61, which can save energy. On the other hand, the movement of the T-rod 75 inside the arc groove 64 can limit the L-shaped plate 71 and prevent the L-shaped plate 71 from automatically moving downward due to gravity.

[0036] The second movable seat 9 includes a vertical plate 91 and a third tooth plate 92 fixed on one side of the vertical plate 91. The vertical plate 91 is slidably connected to the frame 5, and the third tooth plate 92 is meshed with the second gear 55. Second limit blocks 93 are fixedly installed on both sides of the vertical plate 91, and the two second limit blocks 93 are slidably connected to the slide groove 53. The movement of the vertical plate 91 can be limited by cooperating with the two second limit blocks 93 and the slide groove 53 to prevent the vertical plate 91 from separating from the frame 5. A second damper 94 is fixedly installed at one end of the vertical plate 91. The second damper 94 attenuates the vibration amplitude transmitted by the second vibrator 10 through damping materials such as silicone and metal damping plates to avoid damage to the connection structure due to vibration or affecting the stability of the equipment. The second vibrator 10 is fixedly connected to the second damper 94.

[0037] When the output end of the cylinder 61 drives the annular frame 62 to move upward, the L-shaped plate 71 can be driven to move through the connection of the T-shaped rod 75, so that the first vibrator 8 can be driven to move upward. At this time, since the second toothed plate 72 and the third toothed plate 92 are both in meshing connection with the second gear 55, when the second toothed plate 72 moves upward, the third toothed plate 92 is driven to move downward through the rotation of the second gear 55, so that the second vibrator 10 can be driven to move downward, realizing the position interchanging of the first vibrator 8 and the second vibrator 10.

[0038] In order to solve the technical problems of small vibration range and easy to miss the vibration area, such as Figures 3-6 As shown in the drawings, the following preferred technical solutions are provided: The swing member 3 comprises a fixed frame 31 and a serpentine track 32 fixed on one side of the fixed frame 31. Limiting grooves 33 are formed on both sides of the serpentine track 32. The serpentine track 32 and the limiting grooves 33 can limit the movement of the running parts. The serpentine track 32 can force the running parts to change the movement direction during the movement. When the pushing member 4 enters another reverse curved section from one curved section of the serpentine track 32, a transverse offset force is generated, which drives the pushing member 4 connected thereto to swing slightly. The swing action does not need additional power driving, but can be realized by the shape of the serpentine track 32. The number of power sources can be reduced, and the energy consumption can be reduced.

[0039] The pushing member 4 comprises a bottom plate 41 and a housing 42 fixed on one side of the bottom plate 41. An electric push rod 43 is fixedly installed on one side of the housing 42. An installation shell 44 is fixedly installed on the surface of the electric push rod 43 and is fixedly connected with the housing 42. The installation shell 44 is connected with the housing 42 through bolts, so that the electric push rod 43 can be conveniently disassembled and installed. A first toothed plate 45 is slidably connected in the housing 42. An installation block 46 is fixedly installed on one side of the first toothed plate 45 and is fixedly connected with the output end of the electric push rod 43. A T-shaped block 47 is fixedly installed on the surface of the housing 42 and is slidably connected with the moving plate 17. The design of the T-shaped block 47 can make the housing 42 more stably slide in the moving plate 17. A roller 48 is rotatably connected on one side of the T-shaped block 47. The roller 48 can reduce the friction force, so that the T-shaped block 47 can move better in the moving plate 17. The roller 48 is in contact with the inside of the moving plate 17.

[0040] A concave plate 411 is fixedly installed at one end of the base plate 41, and the concave plate 411 is in contact with the serpentine track 32. Rollers 412 are rotatably connected on both sides of the concave plate 411, and the rollers 412 are in contact with the limit slots 33. A rectangular plate 413 is fixedly installed on one side of the base plate 41, and two strip plates 414 are installed on one side of the base plate 41 near the rectangular plate 413. When the screw 14 can drive the movable plate 17 to move, it can drive the base plate 41 and the shell 42 to move back and forth. At the same time, when the base plate 41 moves, the rollers 412 and the inside of the limit slot 33 move. The limiting and guiding of the serpentine track 32 cooperate with the slow movement of the base plate 41 to generate a small left and right swing, thereby expanding the vibration range and reducing the vibration leakage area.

[0041] Traditional insert vibrators rely only on vertical insertion and linear movement, and the vibration range is limited to the circular area around the vibrating rod. If the movement path is not properly controlled, it is easy to cause leakage vibration in the gaps between steel bars, corners of components and other places. Small left and right swings can expand the action area of ​​the first vibrator 8 and the second vibrator 10 from a circular area to a fan-shaped area. The coverage of adjacent vibration points overlaps more, which is especially suitable for areas with dense steel bars or complex components. It can fill the gaps during linear movement and avoid honeycombs and rough surfaces caused by leakage vibration.

[0042] In order to further better explain the above embodiment, the present invention also provides an embodiment, a method for using a production device for prefabricated bridge panels, comprising the following steps: Step 1: In the initial state, the low-position first vibrator 8 and the high-position second vibrator 10 can vibrate the concrete, and the driving frame 1 can drive the pusher 4 to move slowly. The low-position first vibrator 8 vibrates the deep layer of concrete, and the high-position second vibrator 10 moves ahead and acts on the shallow layer. The cooperation of the two forms full-depth vibration coverage of the deep and shallow layers. Step 2: When the low-position first vibrator 8 is about to approach the steel bar, the ultrasonic sensor 20 will detect the presence of the steel bar in the moving direction. Through the pre-judgment of the ultrasonic sensor 20 and the alternating operation of the first vibrator 8 and the second vibrator 10, the roles of the first vibrator 8 and the second vibrator 10 are interchanged, and the primary and secondary vibration areas can be flexibly switched according to the distribution of the steel bars, and deformation of the steel bars or damage to the first vibrator 8 caused by hard collisions can be avoided. Step 3: The pusher 4 is caused to swing slightly during its slow movement by the swinging member 3. The slow movement ensures that the first vibrator 8 and the second vibrator 10 have sufficient action time in each area, while the small swing allows the vibration energy to be gradually diffused to the periphery, gradually transmitting the vibration from the center of the first vibrator 8 and the second vibrator 10 to the edge, avoiding uneven vibration caused by rapid movement, thereby fully improving the vibration effect of the concrete; Step 4: Through the ultrasonic sensor 20's pre-judgment and the alternating operation of the first vibrator 8 and the second vibrator 10, a continuous operation mode is achieved in which the machine does not stop when encountering steel bars and only the working parts are switched. When the first vibrator 8 moves up to avoid, the second vibrator 10 has started vibrating synchronously, avoiding the instantaneous high energy consumption caused by frequent start and stop of a single device, and achieving energy-saving effect.
