Description

Technical Field

[0001] This invention belongs to the field of bridge bearing casting technology, specifically a bridge bearing construction and casting equipment. Background Technology

[0002] Bridge bearings, as the core force-transmitting devices connecting the superstructure (main beams, bridge deck) and substructure (piers, abutments) in a bridge, function similarly to the "joints" of a bridge. They primarily bear the transmission and coordination of vertical loads (including structural self-weight and vehicle live loads), horizontal forces (such as wind loads and seismic forces), and displacements (temperature deformation, shrinkage, creep, etc.). A typical bridge bearing consists of upper and lower connecting plates, a pressure-bearing core layer, sliding components, a rotating mechanism, seismic energy dissipation devices, and a sealing and protection system.

[0003] Currently, the lower connecting plates of bridge bearings mostly adopt steel plates or precast concrete pads. Among them, precast concrete pads are usually cast by molds. In the casting process, the finishing of the top surface of the pad generally relies on manual troweling. However, since it is difficult to maintain uniform and constant force by hand, the flatness of the same working surface is prone to fluctuation, forming a "wavy" defect on the top surface, which in turn affects the installation accuracy of the bearing and the structural stress performance. Therefore, a bridge bearing construction casting equipment is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a bridge bearing construction casting and molding equipment, which solves the problem that the existing bridge bearing lower connecting plate is precast concrete cast in molds and the manual trowel finishing process easily leads to uneven surface flatness and "wavy lines", which affects the bearing installation accuracy and structural stress performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bridge bearing construction casting and molding equipment, comprising a base plate, and further comprising: A mold assembly is disposed on top of the base plate, and concrete is poured into the mold assembly to form a bridge bearing pad stone; A flattening assembly, which is mounted on top of the base plate via a crossbeam frame, is used to flatten the poured concrete. The crossbeam frame is fixedly mounted on the top of the base plate. The flattening assembly includes a driving component disposed in the middle of the crossbeam frame. A first connecting beam frame is fixedly mounted at the output end of the driving component. A second flattening component is fixedly mounted at both ends of the bottom of the first connecting beam frame. The bottom of the first connecting beam is fixedly fitted with a second connecting beam, and the middle of the second connecting beam is movably fitted with a vertical guide rod. The bottom of the vertical guide rod is fixedly fitted with a first pressing member that is aligned and spliced ​​with the second pressing member. The inner wall of the mold assembly is provided with a stop strip that limits the first pressing member and the two second pressing members. When the first pressing member and the two second pressing members overlap on the stop strip, the first pressing member, the two second pressing members and the stop strip form a plane. Concrete is poured into the mold assembly. The driving component pushes two second flattening components and the first flattening component to move down and fit into the mold assembly, flattening the concrete inside the mold assembly.

[0006] Preferably, the mold assembly has discharge pipes connected to its interior at both ends; Concrete is poured into the mold assembly through the middle of the mold assembly, and the thickness of the poured concrete is greater than the actual pouring thickness, and the top surface of the poured concrete is not higher than the discharge pipe.

[0007] Preferably, both ends of the top of the first connecting beam are fixedly equipped with stabilizing guide rods that slide on the crossbeam; The output end of the drive unit moves upward, pulling the first connecting beam and the two second flattening components upward. The second connecting beam moves upward along the vertical guide rod until the top of the second connecting beam contacts the top of the vertical guide rod, and then pulls the first flattening component upward synchronously, so that the bottom height of the two second flattening components is higher than the bottom of the first flattening component.

[0008] Preferably, the mold assembly includes first templates fixed to both ends of the top of the base plate, and the two discharge pipes are respectively installed on the two first templates; The top of the base plate is slidably provided with two second templates and a third template; The two second templates and the three templates are composed of two sets and are set on the sides of the two first templates to form the concrete pad stone mold for the bridge bearing.

[0009] Preferably, a stabilizing component is provided on the top of the base plate. The stabilizing component includes a support frame fixedly mounted on the top of the base plate, a fixed spindle fixedly mounted on the support frame, and a transmission component equidistantly sleeved on the fixed spindle. The protruding end of the transmission component is hinged to a connecting rod via a connecting spindle.

[0010] Preferably, a connecting member is fixedly installed on the outer wall of the second template, a sliding groove is provided in the connecting member, and a sliding member that slides in the sliding groove is hinged to the other end of the connecting rod. A limiting baffle that abuts against the connecting member is fixedly installed at the bottom of the connecting rod near the sliding member end.

[0011] Preferably, a first baffle for limiting the movement of the transmission component is fixedly mounted on the support frame; The transmission component rotates in the opposite direction around the fixed spindle and overlaps the first baffle. The connecting rod pushes the second and third templates to contact the first template to form a pad stone mold. The limiting baffle abuts against the outside of the docking part, so that the transmission component and the connecting rod form a 90° angle, while the connecting rod and the second template form a 45° angle.

[0012] Preferably, a demolding component is fixedly mounted on the flattening component. The demolding component includes a connecting frame fixedly mounted on the second flattening component and the first flattening component. A pulling component is hinged to the side wall of the connecting frame, and a second baffle for limiting the pulling component is fixedly mounted on the side wall of the connecting frame.

[0013] Preferably, both ends of the connecting mandrel are provided with movable parts; After the second and third templates abut against the side of the first template to form a bridge bearing pad stone mold, and after the concrete is poured, the first flattening member, the second flattening member and the connecting frame move down, and the pulling member rotates with the hinge axis of the connecting frame so that the pulling member is located at the bottom of the movable kit.

[0014] Preferably, after the concrete inside the mold assembly has solidified, the second flattening component and the first flattening component move upward, and the connecting frame and the pulling component pull the movable kit, the transmission component and the connecting rod to rotate in the opposite direction, so that the second template and the third template are separated from the first template.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention involves injecting concrete into a mold assembly, with the top surface of the concrete inside the mold assembly higher than the stop bar. After injection, a driving component moves two second flattening components and a first flattening component downwards into the mold assembly. Since the bottom of the first flattening component is lower than the bottom of the two second flattening components, the bottom of the first flattening component contacts the top surface of the concrete first and overlaps with the stop bar to limit the first flattening component. At this time, the driving component continues to push the first connecting beam and the two second flattening components downwards until the two second flattening components overlap with the stop bar. During this process, the top surface of the bridge bearing pad concrete inside the mold assembly is flattened by the first flattening component and the two second flattening components, avoiding the difficulty of maintaining uniform and constant force during manual finishing, which can lead to uneven fluctuations on the working surface and affect the subsequent bearing installation accuracy and structural stress performance.

[0016] This invention involves injecting concrete into a mold assembly. A driving component then moves two second pressing components and a first pressing component downwards into the mold assembly. Since the bottom of the first pressing component is lower than the bottom of the two second pressing components, the bottom of the first pressing component contacts the top surface of the concrete first and overlaps with the baffle. As the first pressing component moves downwards, it pushes the concrete in the middle of the mold assembly to both ends. The baffle limits the movement of the first pressing component. Meanwhile, the driving component continues to push the first connecting beam and the two second pressing components downwards, squeezing the excess concrete towards both ends and discharging it through the discharge pipe until the two second pressing components overlap with the baffle. During this process, the first pressing component and the two second pressing components squeeze the concrete from the middle of the mold assembly towards both ends, preventing hollow areas or missing corners.

[0017] This invention uses a driving component to first pull two second pressing components upwards. Then, through the connecting frames and pulling components on the two second pressing components, the transmission component and connecting rod rotate in the opposite direction. This pulls the two second templates outwards to detach from the solidified concrete. As the second connecting beam moves upwards to the top of the vertical guide rod, it pulls the first pressing component upwards. At this time, through the connecting frames and pulling components on the first pressing component, the third template moves outwards along the top of the base plate. This achieves the purpose of demolding the bridge bearing pad stone and ensures the integrity of the bridge bearing pad stone. It avoids the phenomenon of damage to the bridge bearing pad stone caused by manually striking the outside of the mold with a pry bar or hammer, as is the case with existing methods.

[0028] 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.

[0029] like Figures 1 to 9 As shown, the present invention provides a bridge bearing construction casting and molding equipment, including a base plate 1, and further comprising: Mold assembly 6 is set on the top of the base plate 1, and the bridge bearing pad stone is formed by pouring concrete into the mold assembly 6; Flattening component 5 is set on the top of the base plate 1 via the crossbeam frame 3 and is used to flatten the poured concrete. Among them, the crossbeam frame 3 is fixedly installed on the top of the base plate 1, and the flattening assembly 5 includes a driving member 51 provided in the middle of the crossbeam frame 3. The output end of the driving member 51 is fixedly installed with a first connecting beam frame 53, and the two ends of the bottom of the first connecting beam frame 53 are both fixedly installed with a second flattening member 57. The bottom of the first connecting beam 53 is fixedly fitted with a second connecting beam 54. The middle part of the second connecting beam 54 is movably fitted with a vertical guide rod 55. The bottom of the vertical guide rod 55 is fixedly fitted with a first flattening member 56 that is aligned and spliced ​​with the second flattening member 57. The inner wall of the mold assembly 6 is provided with a stop bar that limits the first pressing member 56 and the two second pressing members 57. When the first pressing member 56 and the two second pressing members 57 overlap on the stop bar, the first pressing member 56, the two second pressing members 57 and the stop bar form a plane. Concrete is poured into mold assembly 6. The driving component 51 pushes the two second flattening components 57 and the first flattening component 56 to move down and fit into the mold assembly 6, flattening the concrete in the mold assembly 6. Both ends of the mold assembly 6 are equipped with discharge pipes 58 that communicate with its interior; Concrete is poured into mold assembly 6 through the middle of mold assembly 6, the thickness of the poured concrete is greater than the actual pouring thickness, and the top surface of the poured concrete is not higher than the discharge pipe 58. Both ends of the top of the first connecting beam 53 are fixedly fitted with stabilizing guide rods 52 that slide on the crossbeam 3; The output end of the drive unit 51 moves upward, pulling the first connecting beam 53 and the two second pressing parts 57 upward. The second connecting beam 54 moves upward along the vertical guide rod 55 until the second connecting beam 54 contacts the top of the vertical guide rod 55. Then, the first pressing part 56 is pulled upward synchronously, so that the bottom of the two second pressing parts 57 is higher than the bottom of the first pressing part 56.

[0030] Initially, the two second flattening members 57 and the first flattening member 56 are disengaged from the mold assembly 6 under the action of the driving member 51, making the top of the mold assembly 6 open. Since the first flattening member 56 slides on the second connecting beam 54 via the vertical guide rod 55, during the upward movement of the first connecting beam 53, the two second flattening members 57 are pulled first, causing the second connecting beam 54 to move upward along the vertical guide rod 55 until it reaches the top of the vertical guide rod 55. Then, the first flattening member 56 is pulled upward via the vertical guide rod 55, forming a situation where the bottom of the first flattening member 56 is lower than the bottom of the two second flattening members 57. Concrete is injected into the mold assembly 6, and the top surface of the concrete inside the mold assembly 6 is higher than the stop bar. After the injection is completed, the driving member 51 drives the two second flattening members 57 and the first flattening member 56 to move downward into the mold assembly 6. Since the bottom of the first flattening member 56 is lower than the bottom of the two second flattening members 57, at this time... The bottom of the first flattening component 56 first contacts the top surface of the concrete and overlaps with the stop strip. As the first flattening component 56 moves downward, it pushes the concrete in the middle of the mold assembly 6 to both ends. The stop strip limits the first flattening component 56. At this time, the driving component 51 continuously pushes the first connecting beam frame 53 and the two second flattening components 57 downward, squeezing the two excess concretes to both ends and discharging them through the discharge pipe 58 until the two second flattening components 57 overlap with the stop strip. During this process, the first flattening component 56 and the two second flattening components 57 squeeze the concrete from the middle of the mold assembly 6 to both ends, avoiding the phenomenon of hollow or missing corners. At the same time, the first flattening component 56 and the two second flattening components 57 achieve the flattening treatment of the top surface of the bridge bearing pad concrete in the mold assembly 6, avoiding the difficulty of maintaining uniform and constant force during manual finishing, which can lead to uneven fluctuations on the working surface and affect the subsequent bearing installation accuracy and structural stress performance.

[0031] It should be noted that the height of the baffle is lower than that of the discharge pipe by 58.

[0032] like Figure 2 , Figures 5-9 As shown, the mold assembly 6 includes a first template 61 fixedly mounted at both ends of the top of the base plate 1, and two discharge pipes 58 respectively installed on the two first templates 61; The top of the base plate 1 is slidably equipped with two second templates 62 and a third template 63; The two second templates 62 and the third template 63 are composed of two sets and are set on the sides of the two first templates 61 to form the concrete pad stone mold for the bridge bearing. The top of the base plate 1 is provided with a stabilizing component 2. The stabilizing component 2 includes a support frame 21 fixedly mounted on the top of the base plate 1. A fixed spindle 24 is fixedly mounted on the support frame 21. A transmission component 23 is equidistantly sleeved on the fixed spindle 24. The protruding end of the transmission component 23 is hinged to a connecting rod 27 via a connecting spindle 25; A connecting piece 28 is fixedly installed on the outer wall of the second template 62. A sliding groove 281 is opened in the connecting piece 28. The other end of the connecting rod 27 is hinged to a sliding piece 282 that slides in the sliding groove 281. A limiting baffle 283 that abuts against the connecting piece 28 is fixedly installed at the bottom of the connecting rod 27 near the sliding piece 282. A first baffle 22 is fixedly mounted on the support frame 21 to limit the movement of the transmission component 23; The transmission component 23 rotates in the opposite direction around the fixed spindle 24 and overlaps the first baffle 22. The connecting rod 27 pushes the second template 62 and the third template 63 to contact the first template 61 to form a pad stone mold. The limiting baffle 283 abuts against the outside of the docking component 28, so that the transmission component 23 and the connecting rod 27 form a 90° angle, while the connecting rod 27 and the second template 62 form a 45° angle.

[0033] By driving the transmission component 23 to rotate around the fixed spindle 24 as the central axis, the connecting rod 27 is driven to move and push the second template 62 and the third template 63 toward the first template 61. When the connecting rod 27 is in a horizontal state, the connecting rod 27 pushes the sliding component 282 to slide along the slide groove 281 until a 90° angle is formed between the transmission component 23 and the connecting rod 27. The sliding component 282 fits against the end of the slide groove 281 away from the second template 62, while the limiting baffle 283 abuts against the outside of the docking component 28. The transmission component 23 overlaps on the first baffle 22. The docking component 28, the limiting baffle 283, the connecting rod 27 and the transmission component 23 support the second template 62 and the third template 63 to form a bridge bearing pad stone mold and ensure the stability of the mold.

[0034] like Figures 5-9As shown, a demolding component 4 is fixedly mounted on the flattening component 5. The demolding component 4 includes a connecting frame 41 fixedly mounted on the second flattening component 57 and the first flattening component 56. A pulling component 43 is hinged to the side wall of the connecting frame 41. A second baffle 42 that limits the pulling component 43 is fixedly mounted on the side wall of the connecting frame 41. Both ends of the connecting spindle 25 are provided with movable parts 26; After the second template 62 and the third template 63 abut against the side of the first template 61 to form the bridge bearing pad stone mold, after the concrete is poured, the first pressing member 56, the second pressing member 57 and the connecting frame 41 move down, and the pulling member 43 rotates with the hinge axis with the connecting frame 41 so that the pulling member 43 is located at the bottom of the movable kit 26. After the concrete inside the mold assembly 6 has solidified, the second pressing component 57 and the first pressing component 56 move upward, and through the connecting frame 41 and the pulling component 43, they pull the movable kit 26, the transmission component 23 and the connecting rod 27 to rotate in the opposite direction, so that the second template 62 and the third template 63 are separated from the first template 61.

[0035] Concrete is injected into mold assembly 6. The top surface of the concrete inside mold assembly 6 is flattened by the downward movement of the flattening assembly 5. During the downward movement of the first flattening component 56 and the second flattening component 57, the connecting frame 41 moves downward synchronously, causing the pulling component 43 to rotate at its hinge point with the connecting frame 41. As the connecting frame 41 continues to move downward, the pulling component 43 is located at the bottom of the movable kit 26. After the concrete has solidified, the driving component 51 first pulls the two second flattening components 57 upward, and then the connecting frame 41 and the pulling component 43 on the two second flattening components 57 pull the transmission component 23. The connecting rod 27 rotates in the opposite direction, thereby pulling the two second templates 62 to move outwards and detach from the solidified concrete. As the second connecting beam 54 moves upwards to the top of the vertical guide rod 55, it pulls the first pressing member 56 upwards. At this time, the connecting frame 41 and the pulling member 43 on the first pressing member 56 pull the third template 63 to move outwards along the top of the base plate 1, thereby achieving the purpose of demolding the bridge bearing pad stone and ensuring the integrity of the bridge bearing pad stone. This avoids the phenomenon of damage to the bridge bearing pad stone caused by manually striking the outside of the mold with a pry bar or hammer.

[0036] Working principle and usage process of this invention: By driving the transmission component 23 to rotate around the fixed spindle 24 as the central axis, the connecting rod 27 is driven to move and push the second template 62 and the third template 63 toward the first template 61. When the connecting rod 27 is in a horizontal state, the connecting rod 27 pushes the sliding component 282 to slide along the slide groove 281 until a 90° angle is formed between the transmission component 23 and the connecting rod 27. The sliding component 282 fits against the end of the slide groove 281 away from the second template 62, while the limiting baffle 283 abuts against the outside of the docking component 28. The transmission component 23 overlaps on the first baffle 22. The docking component 28, the limiting baffle 283, the connecting rod 27 and the transmission component 23 support the second template 62 and the third template 63 to form a bridge bearing pad stone mold. By injecting concrete into the mold assembly 6, with the top surface of the concrete inside the mold assembly 6 higher than the stop bar, after injection, the drive unit 51 drives the two second flattening parts 57 and the first flattening part 56 to move down into the mold assembly 6. Since the bottom of the first flattening part 56 is lower than the bottom of the two second flattening parts 57, the bottom of the first flattening part 56 first contacts the top surface of the concrete and overlaps the stop bar. During the downward movement of the first flattening part 56, the concrete in the middle of the mold assembly 6 is pushed to both ends, and the stop bar limits the first flattening part 56. At this time, the drive component 51 continuously pushes the first connecting beam 53 and the two second pressing components 57 downward, squeezing the two excess concretes to both ends and discharging them through the discharge pipe 58 until the two second pressing components 57 overlap on the stop strip. During this process, the first pressing component 56 and the two second pressing components 57 squeeze the concrete from the middle to both ends of the mold assembly 6 to avoid the phenomenon of hollow or missing corners. At the same time, the first pressing component 56 and the two second pressing components 57 achieve the flattening treatment of the top surface of the bridge bearing pad concrete in the mold assembly 6. The top surface of the concrete inside the mold assembly 6 is flattened by the downward movement of the flattening component 5. During the downward movement of the first flattening component 56 and the second flattening component 57, the connecting frame 41 is moved downward synchronously, causing the pulling component 43 to rotate at the hinge point with the connecting frame 41. As the connecting frame 41 continues to move downward, the pulling component 43 is located at the bottom of the movable kit 26. After the concrete has solidified, the driving component 51 first pulls the two second flattening components 57 upward, and the connecting frame 41 and the pulling component 43 on the two second flattening components 57 pull the transmission component 23 and the connecting rod 27 to rotate in the opposite direction. This pulls the two second templates 62 to move outward first to detach from the solidified concrete. As the second connecting beam frame 54 moves upward to the top of the vertical guide rod 55, it pulls the first flattening component 56 upward. At this time, the connecting frame 41 and the pulling component 43 on the first flattening component 56 pull the third template 63 to move outward along the top of the base plate 1, thus achieving the purpose of demolding the bridge bearing pad stone.
