Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a construction tower crane attachment device and a tower crane. Background Art

[0002] In the construction of high-rise and super high-rise buildings, the installation of the tower crane attachment device attachment support is a crucial step. The traditional installation method is usually to embed the anchor bolts of the attachment support directly into the building structure to achieve a stable installation of the attachment support, thereby improving the safety of the tower crane equipment.

[0003] However, this traditional construction form also has certain limitations. For example, in actual application, it may cause uneven stress on the entire building structure due to uneven local stress. In severe cases, it may even cause cracks in the wall and beam structure, thereby affecting the reliability of the connection between the attachment support and the building structure and the safety of the building structure. Therefore, in the process of pursuing more efficient and safer installation methods, it is particularly important to improve and optimize traditional installation methods.

[0004] Since the attachment support bears a huge alternating load during the use of the tower crane, taking the XCMG XGT6015A-8S tower crane as an example, under ideal installation conditions, the maximum load borne by the attachment support can be as high as about 300kN. However, when the installation conditions at the construction site are limited, the maximum load borne by the attachment support may far exceed this value, and may even increase several times. This high load makes the force distribution of the building structure at the embedded anchor bolts of the attachment support extremely uneven, and only part of the wall and beam structure bears the main load, resulting in uneven force, which in turn weakens the reliability and safety of the connection between the attachment support and the building structure.

[0005] In addition, the traditional design of the anchor bolt embedded parts of the attachment support of the attachment device can usually only be used once and cannot be recycled. When the tower crane construction is completed, the attachment device needs to be removed, and the anchor bolts exposed on the surface of the building structure need to be cut and cleaned. This step not only increases the complexity and difficulty of construction work, but also may increase the safety risks of the construction site. For example, the debris generated by cutting, flying sparks, and the difficulty of high-altitude operations may pose a threat to on-site construction workers.

[0006] To this end, we propose a building tower crane attachment device and a tower crane. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the utility model provides a building tower crane attachment device and a tower crane.

[0008] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is:

[0009] A construction tower crane attachment device comprises: an attachment frame, which is covered and fixed on the circumference of the tower crane; an attachment support, which is fixed to the wall through anchor bolts; an attachment rod, one end of which is hinged to the attachment frame and the other end is hinged to the attachment support; an embedded part, which is buried in the wall, and the anchor bolts pass through the embedded part, and the two ends of which are respectively located on both sides of the wall to tighten and fix the attachment support.

[0010] By setting an embedded part and embedding it in the wall, the anchor bolt passes through the embedded part, and the two ends are located on both sides of the wall and clamped and fixed by nuts. Compared with directly embedding the anchor bolts into the wall, the entire wall is subjected to tension, which makes the wall more evenly stressed, and enhances the reliability and safety of the connection between the attachment support and the wall. When dismantling the attachment device after the tower crane is dismantled after use, we only need to remove the nut of the indoor part of the anchor bolt in the building floor, and the attachment support and the anchor bolt can be removed together. There is no need to dismantle the attachment support through the hanging basket or to clean the anchor bolts protruding from the building structure surface, which greatly improves the disassembly efficiency and safety. The anchor bolts are reusable and reduce the construction cost.

[0011] It is further defined that the embedded parts include embedded plates and embedded tubes, the embedded tubes are vertically arranged on the embedded plates, and the embedded plates are provided with through holes matching the inner diameter of the embedded tubes, the inner diameter of the embedded tubes matches the outer diameter of the anchor bolts, the embedded plate side of the embedded parts is buried outward in the wall, and the length of the embedded tubes matches the thickness of the wall; by embedding the embedded plates into the wall toward the outside of the wall, when the tower crane tilts outward and applies tension to the attached support, the force point is on the inside of the wall instead of on the embedded parts, which can effectively prevent the embedded parts from loosening due to the shaking of the tower crane, and the structure is more stable.

[0012] It is further defined that the attachment support includes a base plate and two ear plates spaced apart on the base plate, a plurality of anchor holes are opened on the base plate, the plurality of anchor holes are arranged in a rectangular array, and the number and positions of the embedded tubes and anchor bolts match the number and positions of the anchor holes.

[0013] It is further defined that a plurality of anti-pull blocks are provided in a fixed ring on the circumference of the embedded tube, and the anti-pull blocks are staggered along the axial direction of the embedded tube; providing the anti-pull blocks on the circumference of the embedded tube can increase the contact area between the embedded tube and the concrete of the wall, making the embedded parts more stable, and can further reduce the impact of the shaking of the tower crane caused by natural weather on the embedded parts.

[0014] It is further defined that the anchor bolt is a double-headed bolt, and two anchor nuts are respectively threadedly connected to both ends of the anchor bolt; by adopting a double-headed bolt as the anchor bolt, the double-headed bolt can provide a more reliable connection compared to a single-headed bolt, reduce the safety risks caused by loose connection, and have a greater load-bearing capacity.

[0015] It is further defined that the attachment rod is a telescopic rod.

[0016] It is further defined that the anchor hole is a strip hole, and the extension direction of the anchor hole is the axial direction of the tower crane; the anchor hole arranged on the attachment support in this way can make the vertical height of the attachment support adjustable, and can adjust the height error between the embedded part and the attachment frame on the actual tower crane.

[0017] A tower crane adopts the above-mentioned building tower crane attachment device.

[0018] The beneficial effects of the utility model are as follows: by arranging embedded parts embedded in the wall, and the anchor bolts pass through both ends of the embedded parts and are located outside the wall, the attachment support is clamped by the anchor nut, so that the disassembly and assembly of the attachment support is safer, the disassembly and assembly efficiency is higher, and it can be reused, saving construction costs.

[0028] The anchor bolts 5 are inserted into the wall 6 to fix the attachment bracket 2.
