Description

Technical Field

[0001] This invention relates to the field of precast beam forming technology, specifically to a precast bridge beam forming mold. Background Technology

[0002] Precast bridge beams are load-bearing components of bridge structures. They are concrete components that are pre-cast in a factory or prefabrication yard using molding molds and then transported to the bridge construction site for installation. Precast bridge beam molding molds are key equipment for achieving standardized production of precast beams, capable of shaping the beams and ensuring their dimensional accuracy. During the use of precast bridge beam molding molds, in order to ensure that the concrete inside the mold is fully compacted and to reduce internal air bubbles and pores, and to ensure that the strength of the beam structure meets the standards, a vibrator is usually used to vibrate the concrete inside the mold.

[0003] Currently available vibratory rods are prone to damage during long-term use or high-intensity vibration. When a vibratory rod is damaged, the machine needs to be stopped for replacement. This not only directly interrupts the vibration operation and reduces the production efficiency of precast beams and slabs, but also causes incompletely vibrated concrete to miss the golden vibration time, thereby reducing the production quality of precast beams and slabs.

[0004] To address the above issues, a precast bridge beam forming mold is proposed. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To address the technical problem of timely replacement of damaged vibratory rods, such as... Figures 1-18 As shown, the following preferred technical solutions are provided: A precast bridge beam forming mold includes a base plate 1, with a U-shaped support frame 2 on top of the base plate 1. The base plate 1 and the U-shaped support frame 2 work together to support and fix various components, such as... Figures 1-2 As shown, a controller 3 is provided on one side of the U-shaped support frame 2. The controller 3 is used to control various electrical components. The controller 3 is existing technology and will not be described in detail here. A mold assembly 4 is provided on the top of the base plate 1. The mold assembly 4 is used to produce precast bridge beams. A first reciprocating sliding assembly 5 is provided inside the U-shaped support frame 2. A lifting assembly 6 is provided at the bottom of the first reciprocating sliding assembly 5. Several second reciprocating sliding assemblies 7 are rotatably arranged inside the lifting assembly 6. A snap-fit ​​assembly 8 is rotatably arranged inside the second reciprocating sliding assembly 7. A first vibration assembly 9 and a second vibration assembly 10 are arranged opposite each other on the top of the snap-fit ​​assembly 8. The first vibration assembly 9 and the second vibration assembly 10 are used independently and not simultaneously. When the first vibration assembly 9 is damaged, it can be replaced in time by the second vibration assembly 10. The first vibration assembly 9 and the second vibration assembly 10 are both connected to the second reciprocating sliding assembly 7. A detection assembly 20 is provided inside the first vibration assembly 9 and the second vibration assembly 10. The detection assembly 20 can detect whether the vibration operation is completed to avoid over-vibration or under-vibration.

[0025] When in use, external concrete is injected into the mold assembly 4. The controller 3 causes the first reciprocating sliding assembly 5 to move the lifting assembly 6, the second reciprocating sliding assembly 7, the first vibrating assembly 9, and the second vibrating assembly 10 to move directly above the vibration area. At this time, the controller 3 causes the lifting assembly 6 to move the first vibrating assembly 9 and the second vibrating assembly 10 down, and the first vibrating assembly 9 vibrates the concrete.

[0026] If the first vibrating component 9 malfunctions and stops during vibration, the controller 3 connects the locking component 8 to the second reciprocating sliding component 7. Simultaneously, the controller 3 disconnects both the first and second vibrating components 9 and 10 from the second reciprocating sliding component 7. Then, the controller 3 causes the second reciprocating sliding component 7 to rotate, thereby causing the first and second vibrating components 9 and 10 to slide inside the second reciprocating sliding component 7, exchanging positions with the first vibrating component 9. The controller 3 then connects the first and second vibrating components 9 and 10 back to the second reciprocating sliding component 7, and the locking component 8 disconnects from the second reciprocating sliding component 7. The replaced second vibrating component 10 then performs vibration, replacing the first vibrating component 9 and continuing the vibration operation. This timely replenishment of vibration workstations shortens vibration interruption time, avoids downtime for replacements affecting work efficiency, prevents missing the optimal vibration time, and improves the production quality of precast bridge beams.

[0027] During the vibration process, the required vibration time varies depending on the concrete characteristics and steel reinforcement distribution in each area. The detection component 20 monitors the vibration status of each area. If the first vibration component 9 or the second vibration component 10 in a certain area completes vibration ahead of schedule, and the detection component 20 detects that the value has reached the baseline value, the controller 3 stops the corresponding first vibration component 9 or second vibration component 10. Then, the controller 3 causes the second reciprocating sliding component 7 to promptly lift the completed first vibration component 9 or second vibration component 10, detaching it from the concrete. The vibrating component rises into the second reciprocating sliding component 7, which can easily avoid over-vibration and achieve dynamic vibration that can be controlled as needed. This ensures the overall uniformity of vibration and the production quality of the precast beams and slabs. If the first vibrating component 9 or the second vibrating component 10 is not raised in time after vibration is completed, it will cause abnormal concrete density in that area, resulting in structural defects. It will also hinder the normal flow and stress of concrete in other areas during vibration, interfering with the overall uniformity of vibration and thus affecting the forming quality of the precast bridge beams and slabs. At this time, the first vibrating component 9 or the second vibrating component 10 in other areas that have not been vibrated continues to vibrate until vibration is completed.

[0028] At this time, the lifting component 6 drives multiple sets of first vibration components 9 or second vibration components 10 to rise. Simultaneously, the first vibration components 9 or second vibration components 10 that have been pre-vibrated are lowered synchronously by the second reciprocating sliding component 7, so that multiple sets of first vibration components 9 or second vibration components 10 are kept in the initial vibration position. At this time, the lifting component 6, the second reciprocating sliding component 7, the first vibration component 9 and the second vibration component 10 are moved by the first reciprocating sliding component 5 to move to the top of the next vibration area for the next cycle of vibration.

[0029] Before vibration, the first vibration component 9 or the second vibration component 10 is raised or lowered by the second reciprocating sliding component 7, so as to facilitate the adjustment of the vibration position of the first vibration component 9 or the second vibration component 10. This allows the vibration depth of the concrete to be pre-adjusted according to the usage requirements, thereby improving the practicality of the device. The lifting component 6 is equipped with a rotating component 30, which is connected to the second reciprocating sliding component 7.

[0030] During the vibration process, if the first vibration component 9 or the second vibration component 10 in a certain vibration area completes vibration ahead of schedule and stops to enter the second reciprocating sliding component 7, and the first vibration component 9 or the second vibration component 10 in the adjacent vibration area has not yet completed vibration, and the value detected by the detection component 20 reaches the start value, the controller 3 causes the rotating component 30 to drive the second reciprocating sliding component 7 to rotate, so that the first vibration component 9 or the second vibration component 10 that has completed vibration ahead of schedule rotates to above the adjacent unvibrated area. At this time, the second reciprocating sliding component 7 drives the first vibration component 9 or the second vibration component 10 that has completed vibration ahead of schedule to descend, and vibration is carried out by the first vibration rod 99 or the second vibration rod 109, which facilitates dynamic scheduling, realizes the coordinated vibration of the two sets of vibration rods, improves resource utilization, and improves work efficiency.

[0031] like Figures 1-3 As shown, the mold assembly 4 includes a bottom template 41 fixedly connected to the top of the base plate 1. First side templates 42 are rotatably connected to both sides of the bottom template 41. A hydraulic cylinder 43 is rotatably connected to the top of the base plate 1. The movable end of the hydraulic cylinder 43 is rotatably connected to the first side templates 42. Two grooves 47 are opened on one side of the bottom template 41 and the two first side templates 42. A second side template 44 is installed in the groove 47. A screw 45 is installed on one side of the second side template 44. A pouring cavity is formed between the bottom template 41, the two first side templates 42, and the two second side templates 44. The screw 45 passes through the second side template 44 and is threadedly connected to the first side template 42. A reinforcing bar body 46 is connected inside the first side template 42. The reinforcing bar body 46 is distributed according to a preset spacing specification, and its arrangement path avoids the replacement trajectory and collaborative vibration operation area of ​​the first vibration assembly 9 and the second vibration assembly 10, thereby avoiding interference with the replacement action and collaborative vibration, and avoiding the risk of motion interference.

[0032] like Figures 1-2 As shown, the first reciprocating sliding assembly 5 includes a first servo motor 51 installed on one side of the U-shaped support frame 2, a first threaded rod 52 rotatably connected inside the U-shaped support frame 2, the output end of the first servo motor 51 being fixedly connected to the first threaded rod 52, a threaded plate 53 being threadedly connected to the outer wall of the first threaded rod 52, a first slide rod 54 being fixedly connected inside the U-shaped support frame 2, and the threaded plate 53 being slidably connected to the first slide rod 54.

[0033] like Figures 1-2 , Figure 4 , Figure 11 and Figure 13 As shown, the lifting assembly 6 includes two electric push rods 61 installed on one side of the threaded plate 53. The movable ends of the two electric push rods 61 are fixedly connected to a U-shaped lifting frame 62, and a horizontal plate 63 is fixedly connected inside the U-shaped lifting frame 62.

[0034] like Figure 1 and Figures 4-16 As shown, the second reciprocating sliding assembly 7 includes several rotating cylinders 71 rotatably connected within the horizontal plate 63. A top plate 72 is provided on the top of the rotating cylinders 71. A second servo motor 73 is installed on the top of the top plate 72. A second threaded rod 74 is rotatably connected inside the top plate 72. The output end of the second servo motor 73 is fixedly connected to the second threaded rod 74. A threaded block 75 is threadedly connected to the outer wall of the second threaded rod 74. A fixing block 77 is fixedly connected to the bottom of the top plate 72. Two second sliding rods 76 are connected opposite each other at the bottom of the fixing block 77. An arc-shaped groove 78 and a vertical groove 79 are respectively opened on the inner wall of the rotating cylinders 71. The arc-shaped groove 78 and the vertical groove 79 are connected.

[0035] like Figure 7 , Figure 9 and Figures 11-14 As shown, the snap-fit ​​assembly 8 includes a rotating ring 81 rotatably connected to the rotating cylinder 71, two second sliding rods 76 oppositely disposed on the top of the rotating ring 81, two first sliders 82 slidably connected inside the rotating ring 81, a first spring 83 fixedly connected to one side of each of the two first sliders 82, and the other end of the first spring 83 fixedly connected to the inner wall of the rotating ring 81, a first electromagnet 84 installed on the inner wall of the rotating ring 81, a first magnet block 85 fixedly connected to one side of each of the two first sliders 82, a snap-fit ​​rod 86 fixedly connected to one side of each of the two first sliders 82, and a first snap-fit ​​groove 87 opened on the inner wall of the rotating cylinder 71. During normal use, the snap-fit ​​rod 86 can be snapped into the first snap-fit ​​groove 87 by the elastic force of the first spring 83, thereby fixing the rotating ring 81 to the rotating cylinder 71. Two second snap-fit ​​grooves 88 are opened opposite each other on the outer wall of the second threaded rod 74.

[0036] like Figures 1-2 , Figure 4 , Figures 6-9 , Figure 11 , Figure 13 and Figures 17-18As shown, the first vibrating assembly 9 includes a first limiting rod 91 fixedly connected to the top of the rotating ring 81. A first connecting block 92 is slidably connected to the outer wall of the first limiting rod 91. A first moving block 93 is fixedly connected to one side of the first connecting block 92. The first moving block 93 is slidably connected to the arc-shaped groove 78 and the vertical groove 79 respectively. A second spring 94 is fixedly connected to the inner wall of the first connecting block 92, and a first U-shaped limiting plate 97 is fixedly connected to the other end of the second spring 94. The first U-shaped limiting plate 97 is slidably connected to the first connecting block 92. Plate 97 is connected to threaded block 75. A second electromagnet 95 is installed on the inner wall of the first connecting block 92. A second magnet block 96 is fixedly connected to one side of the first U-shaped limiting plate 97. A first shock absorber 98 is installed at the bottom of the first connecting block 92. A first vibrating rod 99 is installed at the bottom of the first shock absorber 98. The first shock absorber 98 absorbs the high-frequency vibration generated by the first vibrating rod 99 when it is working. The first vibrating rod 99 generates high-frequency vibration to vibrate the concrete. The first shock absorber 98 and the first vibrating rod 99 are both existing technologies and will not be described in detail here.

[0037] like Figures 4-5 , Figures 7-8 and Figure 10 As shown, the second vibrating assembly 10 includes a second limiting rod 101 fixedly connected to the top of the rotating ring 81. A second connecting block 102 is slidably connected to the outer wall of the second limiting rod 101. A second moving block 103 is fixedly connected to one side of the second connecting block 102. The second moving block 103 is slidably connected to the arc-shaped groove 78 and the vertical groove 79 respectively. A third spring 104 is fixedly connected to the inner wall of the second connecting block 102, and a second U-shaped limiting plate 107 is fixedly connected to the other end of the third spring 104. The second U-shaped limiting plate 107 is slidably connected to the second connecting block 102 and the fixed block 79. 7. A third electromagnet 105 is installed on the inner wall of the second connecting block 102. A third magnet block 106 is fixedly connected to one side of the second U-shaped limiting plate 107. A second shock absorber 108 is installed at the bottom of the second connecting block 102. A second vibrating rod 109 is installed at the bottom of the second shock absorber 108. A through hole is opened through the bottom of the rotating ring 81. The diameter of the through hole is much larger than the diameter of the first vibrating rod 99 and the second vibrating rod 109, so as to facilitate the passage of the first vibrating rod 99 and the second vibrating rod 109, while avoiding the vibration generated by the first vibrating rod 99 or the second vibrating rod 109 during operation from colliding with the rotating ring 81.

[0038] like Figure 11 and Figures 17-18As shown, the detection component 20 includes two pressure sensors 201 respectively installed inside the first vibrating rod 99 and the second vibrating rod 109. The sensing surface of the pressure sensor 201 is made of wear-resistant material to resist the friction and wear of concrete particles. Both the first vibrating rod 99 and the second vibrating rod 109 are provided with protective shells 202, and accelerometers 203 are installed inside the protective shells 202. The protective shells 202 prevent concrete slurry from seeping in and also prevent the accelerometers 203 from being worn by concrete particles. The pressure sensors 201 can detect the real-time reaction force of the concrete on the first vibrating rod 99 or the second vibrating rod 109, and determine the compaction degree of the concrete by the pressure magnitude. The accelerometers 203 can detect the vibration amplitude and frequency of the first vibrating rod 99 or the second vibrating rod 109. The change in vibration rate, through the gradual decrease in vibration energy, indicates the dynamic process of concrete from loose to dense, thus enabling dual detection for easy determination of whether vibration is complete. During the initial calibration of pressure sensor 201 and acceleration sensor 203, the user observes the completion status of concrete vibration. When the concrete vibration is complete, the values ​​of pressure sensor 201 and acceleration sensor 203 serve as the baseline values. When it is necessary to determine whether the rotating component 30 needs to be activated by controller 3 through pressure sensor 201 and acceleration sensor 203, the activation value is preset in controller 3. When the value reaches the activation value, the rotating component 30 of the adjacent completed vibration area is activated by controller 3, realizing dynamic scheduling and coordinating vibration of adjacent uncompleted vibration areas.

[0039] In use, the controller 3 causes the hydraulic cylinder 43 to drive the two first side templates 42 to rotate within the bottom template 41 until the two first side templates 42 are respectively attached to both sides of the bottom template 41. At this time, the second side templates 44 are placed in the grooves 47 respectively, and the second side templates 44 are connected to the first side templates 42 by the screw 45. Then, the steel reinforcement body 46 is fixed in the pouring cavity, and external concrete is injected into the pouring cavity. At this time, the controller 3 causes the first servo motor 51 to drive the first threaded rod 52 to rotate within the U-shaped support frame 2, causing the threaded plate 53 to move on the first slide rod 54, driving the lifting assembly 6, the second reciprocating sliding assembly 7, the first vibration assembly 9, and the second vibration assembly 10 to move to the top of the vibration area. At this time, the controller 3 causes the two electric push rods 61 to drive the U-shaped lifting frame 62 and the horizontal plate 63 to descend, causing the first vibrator 99 to be inserted into the concrete, and the concrete is vibrated by the first vibrator 99.

[0040] If the first vibrating rod 99 is damaged and the machine stops during vibration, the controller 3 causes the first electromagnet 84 to repel the first magnet block 85, causing the first slider 82 to slide within the rotating ring 81 and simultaneously stretching the first spring 83 until the locking rod 86 disengages from the first locking groove 87 and the first slider 82 engages with the second locking groove 88. Simultaneously, the controller 3 causes the second electromagnet 95 to attract the second magnet block 96, causing the first U-shaped limiting plate 97 to slide within the first connecting block 92 and simultaneously compressing the second spring 94 until the first U-shaped... The limiting plate 97 is disconnected from the threaded block 75, and the controller 3 causes the third electromagnet 105 to attract the third magnet block 106, driving the second U-shaped limiting plate 107 to slide within the second connecting block 102, while simultaneously compressing the third spring 104, until the second U-shaped limiting plate 107 is disconnected from the fixed block 77. Then, the controller 3 causes the second servo motor 73 to drive the second threaded rod 74 to rotate, causing the rotating ring 81 to rotate, thereby driving the first moving block 93 and the second moving block 103 to slide within the arc-shaped groove 78. Simultaneously, the first connecting block 92... The outer wall of the first limiting rod 91 slides upward, and the second connecting block 102 slides downward on the outer wall of the second limiting rod 101, causing the first vibrating rod 99 to rotate upward and the second vibrating rod 109 to rotate downward, until the first vibrating rod 99 and the second vibrating rod 109 exchange positions. At this time, the controller 3 causes the second electromagnet 95 and the third electromagnet 105 to release their attraction, causing the second spring 94 to reset, which in turn drives the first U-shaped limiting plate 97 to connect with the fixing block 77, causing the third spring 104 to reset, which in turn drives the second U-shaped limiting plate 107 to connect with the threaded block 75. The controller 3 causes the first electromagnet 84 to release its repulsion, the first spring 83 to reset, and the first slider 82 to release its engagement with the second locking groove 88. At the same time, the locking rod 86 engages with the first locking groove 87 on the opposite side. At this time, the replaced second vibrator 109 is used for vibration, thereby replacing the first vibrator 99 to enter the vibration position and continue the vibration operation. This can promptly fill the gaps in the vibration work position, shorten the vibration interruption time, and avoid downtime for replacement, which affects work efficiency. It also avoids missing the golden vibration time and improves the production quality of bridge precast beams.

[0041] During the vibration process, the required vibration time varies depending on the concrete characteristics and steel reinforcement distribution in each area. Pressure sensor 201 and acceleration sensor 203 monitor the vibration status of each area. If the first vibrator 99 or the second vibrator 109 in a certain vibration area completes vibration ahead of schedule, and the values ​​of pressure sensor 201 and acceleration sensor 203 reach the reference values, the controller 3 stops the first vibrator 99 or the second vibrator 109 in the corresponding vibration area. Then, the controller 3 drives the second servo motor 73 to rotate the second threaded rod 74, causing the threaded block 75 to slide upwards on the outer wall of the second slide bar 76. At this time, the first moving block 93 or the second moving block 103 is in the vertical groove. The vibrator slides upward within 79, thereby causing the first vibrator 99 or the second vibrator 109, which has completed vibration, to rise in time, detach from the concrete, and ascend into the rotating drum 71. This facilitates the avoidance of over-vibration and enables dynamic vibration that can be controlled as needed, thus ensuring the overall uniformity of vibration and the production quality of the precast beams and slabs. If the first vibrator 99 or the second vibrator 109, after vibration, is not raised in time, it will cause abnormal concrete density in that area, resulting in structural defects. It will also hinder the normal flow and stress of concrete in other areas during vibration, interfering with the overall uniformity of vibration and affecting the forming quality of the precast bridge beams and slabs. In this case, the first vibrator 99 or the second vibrator 109 in other areas that have not yet completed vibration continues to vibrate until vibration is complete.

[0042] At this time, the two electric push rods 61 drive multiple sets of first vibrating rods 99 or second vibrating rods 109 to rise. At the same time, since the first vibrating rods 99 or second vibrating rods 109 that have been pre-vibrated are still inside the rotating drum 71, the controller 3 causes the second servo motor 73 to drive the second threaded rod 74 to rotate, causing the threaded block 75 to slide downward on the outer wall of the second slide rod 76, driving the first vibrating rods 99 or second vibrating rods 109 that have been pre-vibrated to descend synchronously, so that the multiple sets of first vibrating rods 99 or second vibrating rods 109 are kept in the initial vibration position. At this time, the first reciprocating sliding assembly 5 drives the lifting assembly 6, the second reciprocating sliding assembly 7, the first vibration assembly 9 and the second vibration assembly 10 to move to the top of the next vibration area for the next cycle of vibration.

[0043] Before vibration, the first vibrating rod 99 or the second vibrating rod 109 is raised or lowered by the second reciprocating sliding component 7, so as to facilitate the adjustment of the vibration position of the first vibrating rod 99 or the second vibrating rod 109. This allows the vibration depth of the first vibrating rod 99 or the second vibrating rod 109 to be pre-adjusted according to the usage requirements, thereby improving the practicality of the device.

[0044] To address the technical problem of the vibratory rods being idle after premature compaction and subsequent shutdown and hoisting, such as... Figure 4 , Figure 6 , Figure 11 and Figure 13 As shown, the following preferred technical solutions are provided: like Figure 4 , Figure 6 , Figure 11 and Figure 13 As shown, the rotating assembly 30 includes a protective shell 301 fixedly connected to the top of the horizontal plate 63, a motor 302 installed at the bottom of the horizontal plate 63, the motor 302 having a self-locking function, a rotating shaft 303 rotatably connected inside the horizontal plate 63, the rotating shaft 303 being fixedly connected to the output end of the motor 302, a gear 304 being fixedly connected to the outer wall of the rotating shaft 303, a gear ring 305 being fixedly connected to the outer wall of the rotating cylinder 71, the gear ring 305 meshing with the gear 304, and the protective shell 301 fitting against the outer wall of the rotating cylinder 71.

[0045] During the vibration process, if the first vibrating rod 99 or the second vibrating rod 109 in a certain vibration area completes vibration ahead of schedule and stops to enter the rotating drum 71, while the first vibrating rod 99 or the second vibrating rod 109 in the adjacent vibration area has not yet completed vibration, and the values ​​of the pressure sensor 201 and the acceleration sensor 203 reach the start value, the controller 3 will cause the motor 302 to drive the rotating shaft 303 and the gear 304 to rotate. Through the meshing of the gear 304 and the gear ring 305, the gear ring 305 and the rotating shaft 303 will be driven to rotate. The cylinder 71, the first vibrating rod 99, and the second vibrating rod 109 rotate, causing the first vibrating rod 99 and the second vibrating rod 109, which have completed vibration in advance, to rotate above the adjacent unvibrated area. At this time, the second reciprocating sliding component 7 drives the first vibrating rod 99 and the second vibrating rod 109, which have completed vibration in advance, to descend and vibrate through the first vibrating rod 99 or the second vibrating rod 109. This facilitates dynamic scheduling, enables the two sets of vibrating rods to vibrate in tandem, improves resource utilization, and enhances work efficiency.
