Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and particularly relates to a double-column climbing device based on a beam body and an attaching device. BACKGROUND

[0002] In the construction of high-rise building concrete core tube, the overall lifting platform usually relies on the vertical wall as the fulcrum due to its large weight. However, with the development trend of lightweight of the lifting platform, the weight is gradually reduced, and the stress of the fulcrum is also reduced accordingly, so it is possible to use the beam body as the fulcrum. In addition, in the high-rise office building using concrete structure, the outer ring of the structure usually lacks wall, and only the inner ring core tube part has wall, which brings challenges to the arrangement of the fulcrum of the lifting platform, so that the conventional wall cannot be used as the fulcrum attachment part. Therefore, in this type of building, the application of the lifting platform is almost non-existent.

[0003] Therefore, it is urgent to provide a device that can more flexibly arrange the position of the fulcrum of the lifting platform, so as to be not limited by the position of the wall, so that the lifting platform can be applied to a more common concrete structure system, thereby expanding the application range of the lifting platform. SUMMARY

[0004] In view of the limitations of the existing fulcrum structure of the lifting platform, the present application provides a double-column climbing device based on a beam body and an attaching device, which can more flexibly arrange the position of the fulcrum compared with the traditional wall attaching device, effectively overcoming the defects of the prior art.

[0005] In order to achieve the above purpose, the present application provides a double-column climbing device based on a beam body, which is symmetrically arranged and sequentially passes through the holes arranged on both sides of the main beam. The top of the climbing device is connected with the lifting platform through the setting of a conversion beam, and the load of the lifting platform is transmitted to the climbing device through the conversion beam.

[0006] Further, the double-column climbing device is respectively and intermittently provided with a climbing hole.

[0007] To achieve the above objectives, the present invention provides an attachment device, which is spaced apart and connected to the floor slab, and also connected to the double-column climbing device. This device is used to attach the climbing device to the main structural beam, transferring the load of the lifting platform to the attachment device via the climbing device, and then to the structural beam via the attachment device. The attachment device includes a first steel beam and a second steel beam. The first steel beam is arranged symmetrically laterally, and its bottom is provided with a connecting component for fixed connection to the floor slab. The second steel beam is vertically symmetrically placed on the first steel beam. Each second steel beam has a first latch on one side opposite the climbing track, which can only rotate in one direction and is used to extend into the climbing hole of the climbing track.

[0008] Furthermore, the inner opposite surfaces of the first steel beam are respectively provided with horizontal limiting devices for limiting the horizontal deviation of the climbing track.

[0009] Furthermore, a connector is provided on the end face of the second steel beam, and the connector is equipped with a driving device.

[0010] Furthermore, the drive devices are symmetrically arranged and their bottoms are connected to the connectors on the attachment device via pins.

[0011] Furthermore, a second latch is provided on the side of the drive device relative to the climbing track for contacting the climbing device.

[0012] Furthermore, the end of the drive device is also provided with a slot, which engages with the climbing rail to limit the positional relationship between the hydraulic cylinder and the climbing rail.

[0013] The present invention provides a beam-based double-column climbing device and attachment device. Compared with traditional wall attachment devices, this device can arrange the position of the support points more flexibly, thus not being limited by the position of the wall. This allows the lifting platform to be applied to more common concrete structure systems, thereby expanding the application range of the lifting platform.

[0014] Secondly, the device adopts a prefabricated structure, with simple and clear node construction, and is easy to disassemble and install, making it flexible and easy to operate. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0023] This invention provides a beam-based double-column climbing device and attachment device. It innovatively proposes a double-column climbing method, with the two columns located on both sides of the beam. The load of the lifting platform is transferred to the main beam through an attachment mechanism. Compared to traditional wall attachment devices, this device allows for more flexible placement of the support points, thus overcoming the limitations imposed by the wall location. This enables the lifting platform to be applied to a wider range of concrete structural systems, thereby expanding its application scope. The device is lightweight, easy to operate, and highly economical.

[0024] See Figures 1-2 Each lifting platform 4 is divided into two climbing devices 1 by a transfer beam 5. The two climbing devices 1 are attached to the main structural beam 6 at intervals by attachment devices 2. The load is transferred to the two climbing devices 1 by the transfer beam 4, and then to the main structural beam 6 by the attachment devices 2.

[0025] Secondly, the attachment device 2 is also equipped with a drive device 3. The lifting device 3 can lift the climbing device 1 and the lifting platform 4 set on the climbing device 1 to the next floor until the lifting platform completes the climbing of the entire floor height.

[0026] Furthermore, the climbing device in this scheme is a climbing track 1, which is symmetrically distributed, and the climbing track 1 is respectively installed through the openings 7 on both sides of the main beam 6.

[0027] The climbing track 1 is connected to the lifting platform 4 via a transfer beam 5. The load of the lifting platform 4 can be transferred to the two climbing tracks 1 via the transfer beam 5, and the two climbing tracks 1 then transfer the load to the attachment device 2.

[0028] Climbing holes 11 are provided at intervals on each climbing track 1. These climbing holes 11 are used to support the attachment device 2 and the drive device 3.

[0029] The attachment devices 2 are spaced apart and connected to the floor slab. They are used to connect with the climbing device 1, allowing the climbing device 1 to attach to the main structural beam 6. See also Figure 3 The attachment device 2 includes a first steel beam 23 and a second steel beam 25.

[0030] The first steel beam 23 is arranged symmetrically in the transverse direction, and its bottom is provided with a connecting component 21 for fixed connection with the floor slab. The first steel beam 23 contacts the floor through the connecting component 21, which can transfer the load force to the main structural beam 6.

[0031] Furthermore, the inner sides of the symmetrically arranged first steel beam 23 are respectively provided with horizontal limiting components 24, and the climbing rail 1 is located between the horizontal limiting components 24. The climbing rail 1 can be limited on both sides to restrict the horizontal deviation of the climbing rail 1.

[0032] The second steel beam 25 is vertically symmetrically placed on the first steel beam 23. Each second steel beam 25 has a first latch 22 that can only rotate in one direction on one side opposite to the climbing track 1. The first latch 22 is used to extend into the climbing hole 11 of the climbing track 1. The first latch 22 can only rotate upward and cannot rotate downward. Therefore, in the non-working state, since the first latch 22 cannot rotate downward, it can support the climbing track 1, so that the climbing track 1 is attached to the main beam 6 of the structure.

[0033] Further, see Figures 3-4 Each second steel beam 25 is also provided with a connector 26 on its end face. The connector 26 is used to hinge with the drive device 3. Through the cooperation of the drive device 3 and the attachment device 2, the climbing track 1 and the lifting platform 4 connected to the climbing track 1 can be lifted.

[0034] In this scheme, the drive device 3 consists of two sets of drive cylinders, which are symmetrically arranged and connected to the connector 26 on the attachment device 2 at their bottoms via pins.

[0035] See Figure 4 The drive end of the drive cylinder 3 is symmetrically provided with a second latch 31 on one side of the climbing track. The second latch 31 is hook-shaped and can be engaged in the climbing hole 11 of the climbing track 1. When the drive cylinder 3 extends, it can form an upward supporting force on the climbing track 1 through the second latch, thereby driving the climbing track 1 to climb.

[0036] Furthermore, the drive end of the drive cylinder 3 is provided with a track groove 32. The track groove 32 is located at the end and engages with the climbing track 1 to limit the positional relationship between the drive cylinder 3 and the climbing track 1.

[0037] The climbing device 1 is connected to the lifting platform 4 through the transfer beam 5, which can transfer the load force of the lifting platform 4 to the climbing device 1. The climbing device 1 is connected in cooperation with the attachment device 2. The attachment device 2 is connected to the floor slab through the connecting component 21, which can transfer the structural force of the lifting platform 4 to the main structural beam 6.

[0038] Meanwhile, one end of the drive device 3 is connected to the attachment device 2, and the other end contacts the climbing track 1 through the latch 31. Through the extension and retraction movement of the drive device 3, and in conjunction with the unidirectional rotation of the first latch 22 on the attachment device 2, the climbing track 1 can be made to continuously climb upward.

[0039] The working process of the beam-based double-column climbing device and attachment device constructed based on the above scheme is illustrated below with an example:

[0040] In the working state, the attachment device 2 is connected to the floor slab of the main structural beam 6, and its first latch 22 is locked in the climbing hole 11 of the climbing rail 1. Since the first latch 22 is unidirectional and cannot rotate downward, it provides support for the climbing rail 1, so that the climbing rail 1 rests on the attachment device 2 and the main structural beam 6 through the first latch 22 of the attachment device 2.

[0041] During the lifting process, the second latch 31 on the upper part of the drive cylinder 3 extends into the climbing hole 11 of the climbing track, and then the drive cylinder 3 extends, driving the second latch 31 until it hits the upper surface of the climbing hole 11. The drive cylinder 3 continues to extend, and the second latch 31 provides upward support to the climbing track 1, pulling the climbing track 1 upward. At the same time, during the climbing process, the climbing device 1 disengages from the first latch 22 of the attachment device 2, and the first latch 22 of the attachment device 2 can rotate upward to avoid obstructing the climbing of the column.

[0042] Then the drive cylinder 3 continues to extend until the first latch 22 of the attachment device 2 enters the next climbing hole. At this time, the cylinder retracts until the first latch in the attachment device 2 abuts against the climbing hole at the climbing opening.

[0043] Then continue to retract the drive cylinder 3, so that the second latch 31 in the drive cylinder 3 enters the next climbing hole, thus completing one lifting stroke.

[0044] Repeat the above steps until the lifting platform has climbed to the full floor height.

[0045] The double-column climbing device and attachment device based on the beam structure constructed by the above scheme can arrange the position of the support points more flexibly compared with the traditional wall attachment device, so it is not limited by the position of the wall. This allows the lifting platform to be applied to more common concrete structure systems, thereby expanding the application range of the lifting platform.

[0046] Secondly, the device adopts a prefabricated structure, with simple and clear node construction, and is easy to disassemble and install, making it flexible and easy to operate.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
