Description

Technical Field

[0001] This application relates to the field of prefabricated component technology, and in particular to a lifting device for prefabricated building components. Background Technology

[0002] Prefabricated building components refer to building components that are prefabricated in factories or production bases and then assembled and installed on site. The main purpose of this construction method is to improve construction efficiency, reduce costs, and improve building quality.

[0003] The existing production process for prefabricated composite slabs involves placing a bottom formwork in the factory area, tying steel bars on the bottom formwork, installing side formwork, pouring concrete, manually prying open and removing the side formwork after the concrete has set, and finally using a robotic arm to transport the composite slabs.

[0004] The manual removal of side molds is inefficient, resulting in low production efficiency of prefabricated composite panels. Summary of the Invention

[0005] In order to achieve rapid demolding of prefabricated composite slabs and thus improve the production efficiency of prefabricated composite slabs, this application provides a lifting device for prefabricated building components.

[0006] The lifting device for prefabricated building components provided in this application adopts the following technical solution:

[0007] A lifting device for prefabricated building components includes a base, a bottom mold and a side mold are provided on the top surface of the base, the side mold surrounds the bottom mold, a lifting rod is slidably disposed in the base, the lifting rod is connected to the bottom of the bottom mold, and a lifting assembly for driving the lifting rod to rise and fall is provided in the base.

[0008] By adopting the above technical solution, the tied steel bars are hoisted onto the bottom formwork, and then concrete is poured. After the concrete is formed, the lifting assembly is activated. The lifting assembly drives the lifting rod upward, which in turn moves the bottom formwork upward. The bottom formwork causes the composite slab to gradually separate from the side formwork. When the bottom formwork completely extends out of the space enclosed by the side formwork, the composite slab is completely separated from the side formwork. Subsequently, the composite slab can be directly transferred using clamps, realizing rapid demolding of the prefabricated composite slab and thus improving the production efficiency of the prefabricated composite slab.

[0009] Optionally, the lifting assembly includes a hydraulic motor disposed within the base. The hydraulic motor is connected to a first rotating shaft, which is connected to a swing rod. A ring block that moves up and down under the rotation of the swing rod is slidably connected within the base. The swing rod passes through the ring block, and the lifting rod is connected to the ring block.

[0010] By adopting the above technical solution, the hydraulic motor drives the first rotating shaft to rotate, the first rotating shaft drives the swing rod to rotate, the swing rod drives the ring block to move up and down, and the ring block drives the lifting rod to rise and fall, thereby realizing the bottom formwork driving the concrete to rise and fall away from the side formwork.

[0011] Optionally, the ring block includes two guide plates, both of which are arc-shaped plates. The ends of the two guide plates are connected by an ear plate, and the ear plate has a guide groove on the side facing the guide plate.

[0012] By adopting the above technical solution, when the swing rod rotates upward, it first moves from the top of the guide plate to the end of the guide plate and enters the guide groove. As the swing rod continues to rotate upward, it goes out of the guide groove and pushes the guide plate upward. When the swing rod completely goes out of the guide groove, the lifting rod reaches the top. The swing rod continues to move along the arc of the guide plate to the other end of the guide plate. As it continues to rotate, the swing rod enters the guide groove of the ear plate at the other end. Then the swing rod continues to rotate downward and drives the guide plate downward. When the swing rod goes out of the guide groove and moves to the top of the guide plate again, both the lifting rod and the swing rod are at the lowest point. By repeatedly performing the above operation, the repeated raising and lowering of the top plate rod can be achieved.

[0013] Optionally, the base is provided with a slide rail, a slide plate is slidably connected to the slide rail, a guide plate is disposed on the slide plate, a connecting plate is connected to the end of the slide plate away from the guide plate, and the lifting rod is connected to the connecting plate.

[0014] By adopting the above technical solution, the connecting plate can easily adjust the distance between the lifting rod and the guide plate, so that the lifting rod can be adjusted to the center of the base.

[0015] Optionally, the connecting plate is provided with a positioning groove, and one end of the lifting rod is inserted into the positioning groove.

[0016] By adopting the above technical solution, the lifting rod can be raised and lowered more stably, reducing the shaking of the lifting rod.

[0017] Optionally, the base is provided with a rotating component for rotating the lifting rod after it has risen to its apex.

[0018] By adopting the above technical solution, when the lifting rod rises to the top, the composite plate is completely separated from the side mold, and then the clamp is fixed. Subsequently, the rotating component drives the bottom mold to rotate, thereby separating the bottom mold from the composite plate, which facilitates the removal of the bottom mold.

[0019] Optionally, the rotating assembly includes a rotating sleeve, which is rotatably disposed within the base. The lifting rod passes through the rotating sleeve and is fixed thereto. A first rotating wheel and a second rotating wheel are rotatably connected within the base. The first rotating wheel is disposed on a first rotating shaft. The first rotating wheel and the second rotating wheel are wound together with a belt. A lever is disposed on the second rotating wheel. A guide groove is provided on the rotating sleeve to cause the lever to drive the rotating sleeve to rotate.

[0020] By adopting the above technical solution, the hydraulic motor drives the first rotating shaft to rotate, the first rotating shaft drives the first rotating wheel to rotate, and when the first rotating wheel rotates, the lifting rod begins to rise. At the same time, the first rotating wheel drives the second rotating wheel to rotate, and the second rotating wheel drives the lever to rotate. When the swing rod drives the guide plate to the top and the swing rod just exits the guide groove, the lever just enters the guide groove. When the swing rod moves from one end of the guide plate to the other end of the guide plate, the lever slides in the guide groove and drives the rotating sleeve to rotate. When the swing rod moves the lifting rod downward, the lever just disengages from the guide groove, so that the rotating sleeve drives the lifting rod to rotate at the top.

[0021] Optionally, two levers are provided, and the guide groove includes a first inclined groove and a second inclined groove. The first inclined groove and the second inclined groove are both provided along the side of the rotating sleeve. The first inclined groove and the second inclined groove have opposite inclination directions and are interconnected. The two levers are arranged opposite to each other about the second rotating wheel and are located on the same line.

[0022] By adopting the above technical solution, when the swing rod drives the guide plate to the top and the swing rod just exits the guide groove, a lever just enters the first inclined groove. When the swing rod moves from one end of the guide plate to the other end, the lever slides in the first inclined groove and drives the rotating sleeve to rotate. When the swing rod moves the lifting rod downward, the lever just disengages from the first inclined groove. Then, when the swing rod drives the lifting rod to descend and rises again to the top, the first rotating wheel just rotates half a turn and another lever enters the second inclined groove. The setting of the first and second inclined grooves ensures that the lifting rod rotates 180 degrees each time, so that the bottom mold will not collide with the side mold when it descends.

[0023] Optionally, two limiting grooves are formed on both the top and bottom surfaces of the rotating sleeve. One of the two limiting grooves on the top surface of the rotating sleeve communicates with the first inclined groove, and the other communicates with the second inclined groove. One of the two limiting grooves on the bottom surface of the rotating sleeve communicates with the first inclined groove, and the other communicates with the second inclined groove. Two limiting plates are provided on the first rotating wheel. The two limiting plates are arc-shaped plates and are symmetrically arranged about the two levers.

[0024] By adopting the above technical solution, when the lever leaves the limiting groove, the limiting plate just enters the limiting groove, and when the lifting rod returns to the top, the limiting plate just moves away from the limiting groove, and another lever extends back into the guide groove.

[0025] Optionally, a support plate is connected to the end of the lifting rod away from the ring block, and the support plate supports the bottom mold.

[0026] By adopting the above technical solution, the contact area between the lifting rod and the bottom mold is increased.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Hoist the tied steel bars onto the bottom formwork, then pour concrete. After the concrete has set, start the lifting assembly. The lifting assembly drives the lifting rod upward, which in turn moves the bottom formwork upward. The bottom formwork gradually separates the composite slab from the side formwork. When the bottom formwork is completely outside the space enclosed by the side formwork, the composite slab is completely separated from the side formwork. Then, the composite slab can be directly transferred using clamps, achieving rapid demolding of the prefabricated composite slab and thus improving the production efficiency of the prefabricated composite slab.

[0029] 2. When the lifting rod rises to the top, the composite plate is completely separated from the side mold, and then the clamp is fixed in place. Subsequently, the rotating assembly drives the bottom mold to rotate, thereby separating the bottom mold from the composite plate, which facilitates the removal of the bottom mold.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a lifting device for prefabricated components of prefabricated buildings.

[0037] like Figure 1 and Figure 2 The lifting device for prefabricated building components includes a base 1, which is a hollow structure. The top surface of the base 1 is provided with a bottom mold 2 and a side mold 3. Four side molds 3 are provided and surround the bottom mold 2. A lifting rod 4 is slidably provided on the base 1. One end of the lifting rod 4 that extends out of the base 1 is connected to a support plate 41. A lifting component 5 for driving the lifting rod 4 to rise and fall is provided inside the base 1. A rotating component 6 for rotating the lifting rod 4 after it rises to the top is also provided inside the base 1.

[0038] The tied steel bars are hoisted onto the bottom formwork 2, and then concrete is poured. After the concrete is formed, the lifting assembly 5 is activated. The lifting assembly 5 drives the lifting rod 4 to push upward, and the lifting rod 4 drives the bottom formwork 2 to move upward. The bottom formwork 2 drives the composite plate to gradually separate from the side formwork 3. When the bottom formwork 2 is completely extended out of the space enclosed by the side formwork 3, the composite plate is completely separated from the side formwork 3. Then, the composite plate can be clamped by the clamps, and the rotating assembly 6 drives the bottom formwork 2 to rotate, thereby separating the bottom formwork 2 from the composite plate. This facilitates the dismantling of the bottom formwork 2 and the transfer of the composite plate, realizing the rapid demolding of the prefabricated composite plate, thereby improving the production efficiency of the prefabricated composite plate.

[0039] like Figure 2 , Figure 3 and Figure 4 The lifting assembly 5 includes a hydraulic motor 51, and the rotating assembly 6 includes a first rotating wheel 61. The hydraulic motor 51 is disposed within the base 1 and connected to a first rotating shaft 52. The first rotating wheel 61 is disposed on the first rotating shaft 52, and the first rotating shaft 52 is connected to a swing rod 53. A slide rail 54 is disposed within the base 1, and a sliding plate 55 is slidably disposed on the slide rail 54. A ring block 56 is disposed on the sliding plate 55, and the swing rod 53 passes through the ring block 56.

[0040] The ring block 56 includes two arc-shaped plates, which are parallel to each other and are both set on the sliding plate 55. The ends of the two arc-shaped plates are connected by ear plates 562, and each ear plate 562 has a guide groove 563 at its opposite end.

[0041] A connecting plate 57 is fixed to the top of the sliding plate 55. The connecting plate 57 is perpendicular to the sliding plate 55 and has a positioning groove 571. One end of the lifting rod 4 is inserted into the positioning groove 571 and rotatably connected to the connecting plate 57. A rotating sleeve 62 is rotatably connected to the base 1. A guide groove 63 is provided on the rotating sleeve 62. The guide groove 63 includes a first inclined groove 631 and a second inclined groove 632. The first inclined groove 631 and the second inclined groove 632 have opposite inclination directions and are staggered. Both the first inclined groove 631 and the second inclined groove 632 are opened along the rotating sleeve 62.

[0042] Both the top and bottom surfaces of the rotating sleeve 62 are provided with limiting grooves 64. The two limiting grooves 64 on the top surface of the rotating sleeve 62 are arranged opposite to each other, with the first inclined groove 631 communicating with one of the limiting grooves 64 and the second inclined groove 632 communicating with the other limiting groove 64. The two limiting grooves 64 on the bottom surface of the rotating sleeve 62 are also arranged opposite to each other, with the first inclined groove 631 communicating with one of the limiting grooves 64 and the second inclined groove 632 communicating with the other limiting groove 64.

[0043] A second rotating wheel 65 is rotatably mounted on the base 1. The diameter of the second rotating wheel 65 is twice that of the first rotating wheel 61. A belt 66 is mounted on both the first rotating wheel 61 and the second rotating wheel 65. The second rotating wheel 65 is rotatably connected to the base 1 via a rotating shaft. Two levers 67 are mounted on the rotating shaft of the second rotating wheel 65. The two levers 67 are located on the same straight line. Two limiting plates 68 are mounted on the rotating shaft of the second rotating wheel 65. The two limiting plates 68 are arc-shaped plates and are symmetrically arranged about the two levers 67.

[0044] The hydraulic motor 51 drives the first rotating shaft 52 to rotate, and the first rotating shaft 52 drives the swing rod 53 to rotate. When the swing rod 53 rotates upward, it first moves from the top of the guide plate 561 to the end of the guide plate 561 and enters the guide groove 563. As the swing rod 53 continues to rotate upward, it goes out of the guide groove 563 and pushes the guide plate 561 upward. When the swing rod 53 has completely gone out of the guide groove 563, the lifting rod 4 reaches the top. The swing rod 53 continues to move along the arc of the guide plate 561 to the other end of the guide plate 561. The swing rod 53 continues to rotate and enters the guide groove 563 of the ear plate 562 at the other end. Then the swing rod 53 continues to rotate downward and drives the guide plate 561 to move downward. When the swing rod 53 goes out of the guide groove 563 and moves to the top of the guide plate 561 again, the lifting rod 4 and the swing rod 53 are both at the lowest point. By repeatedly performing the above operation, the lifting rod 4 can be repeatedly raised and lowered.

[0045] When the first rotating wheel 61 rotates, the lifting rod 4 begins to rise. At the same time, the first rotating wheel 61 drives the second rotating wheel 65 to rotate, and the second rotating wheel 65 drives the lever 67 to rotate. When the swing rod 53 drives the guide plate 561 to the top and the swing rod 53 just exits the guide groove 563, the lever 67 just enters the guide groove 63. When the swing rod 53 moves from one end of the guide plate 561 to the other end, the lever 67 slides in the guide groove 63 and drives the rotating sleeve 62 to rotate. When the swing rod 53 moves the lifting rod 4 downward, the lever 67 just disengages from the guide groove 63, so that the rotating sleeve 62 drives the lifting rod 4 to rotate at the top.

[0046] When the swing rod 53 drives the guide plate 561 to the top, and the swing rod 53 just exits the guide groove 563, a lever 67 just enters the first inclined groove 631. When the swing rod 53 moves from one end of the guide plate 561 to the other end, the lever 67 slides in the first inclined groove 631 and drives the rotating sleeve 62 to rotate. When the swing rod 53 moves the lifting rod 4 downward, the lever 67 just disengages from the first inclined groove 631. Then the swing rod 53 drives the lifting rod 4 to descend and rise again to the top. At this time, the first rotating wheel 61 just rotates half a turn and causes another lever 67 to enter the second inclined groove 632. The setting of the first inclined groove 631 and the setting of the second inclined groove 632 ensures that the lifting rod 4 rotates 180 degrees each time, so that the bottom mold 2 will not collide with the side mold 3 when it descends.

[0047] The implementation principle of this application embodiment is as follows: the tied steel bars are hoisted onto the bottom formwork 2, and then concrete is poured. After the concrete is formed, the lifting component 5 is activated. The lifting component 5 drives the lifting rod 4 to push upward, and the lifting rod 4 drives the bottom formwork 2 to move upward. The bottom formwork 2 drives the composite plate to gradually separate from the side formwork 3. When the bottom formwork 2 completely extends out of the space enclosed by the side formwork 3, the composite plate is completely separated from the side formwork 3. Then, the composite plate can be clamped by the clamps, and the rotating component 6 drives the bottom formwork 2 to rotate, thereby separating the bottom formwork 2 from the composite plate, facilitating the dismantling of the bottom formwork 2 and the transfer of the composite plate, realizing the rapid demolding of the prefabricated composite plate, thereby improving the production efficiency of the prefabricated composite plate.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
