Description

Technical Field

[0001] This utility model relates to the field of attachment components, and in particular to a modular, weld-free, quick-installation tower crane boiler attachment component device. Background Technology

[0002] Tower cranes, also known as tower cranes, are used in the construction of high-rise buildings. They need to be connected to the building structure, such as the steel structure columns of a boiler room, through attachment devices to increase their stability and attachment height. These devices that connect the tower crane to the building structure are collectively called tower crane attachment devices.

[0003] Traditional tower crane boiler attachment components typically employ welding connections. Specifically, connecting plates or brackets are usually welded onto the boiler's steel structure columns first. Then, the crossbeams, struts, and other components of the attachment device are fixedly connected to these pre-welded parts through on-site welding. Finally, the attachment is connected to the tower crane body via attachment tie rods.

[0004] However, the aforementioned existing technologies still have some obvious drawbacks. First, the large amount of on-site welding work is inefficient and requires a high level of technical skill from the operators. Second, the thermal stress generated by welding may affect the performance of the steel structure base material, posing a potential quality hazard. Finally, this connection method is a permanent connection, and cutting is required during disassembly, which is not only difficult to carry out but also causes significant damage to the components, making it difficult to reuse and resulting in a waste of materials.

[0025] Example: Please see Figure 1-5 A modular, weld-free, quick-assembly tower crane boiler attachment assembly device includes: a crossbeam 1, with clamps 2 at both ends that can adapt to columns 3 of different sizes; the crossbeam 1 and clamps 2 are pre-connected by bolts; the crossbeam 1 is provided with lifting lugs 11 for hoisting and is located on the outside of the column 3, and is limited and fixed by pins; a fastening structure 4 for locking the clamps 2 to the column 3; an attachment frame 5 and an attachment rod 6, one end of the attachment rod 6 is connected to the attachment frame 5, and the other end is detachably connected to the crossbeam 1.

[0026] The modular, weld-free, quick-assembly tower crane boiler attachment assembly device of this application is mainly composed of a crossbeam 1, a clamp 2, a fastening structure 4, an attachment frame 5, and an attachment tie rod 6.

[0027] The crossbeam 1 is the core load-bearing component of the entire device, made of high-strength steel. Its two ends are pre-connected to clamps 2 with high-strength bolts, forming a rigid portal frame module. Lifting lugs 11 are welded onto the crossbeam 1 for hoisting the entire module. Several drainage holes 12 are provided at the bottom of the crossbeam 1 to drain accumulated rainwater or condensate, effectively preventing internal corrosion and extending its service life. Connecting ear plates 13 are also provided at both ends of the crossbeam 1 for detachable hinged connection to the lower end of the attached tie rod 6 via pins.

[0028] The clamp 2 is a key component for clamping and fixing the clamp to the column 3, which is an H-shaped steel structure. The clamp 2 is composed of several standard-sized steel plates 21 connected by high-strength bolts, forming a modular structure that can adapt to H-shaped steel columns 3 of different sizes. This design allows for flexible adjustment of the assembly method and size of the clamp 2 on site according to the actual cross-sectional dimensions, height, width, and flange thickness of the column 3, achieving a high degree of adaptability and flexibility. The clamp 2 has a pin hole 211 for engaging with a pre-drilled hole on the column 3 to insert a pin for initial positioning.

[0029] The fastening structure 4 is used to finally eliminate the gap between the clamp 2 and the flange of the H-beam column 3 and provide a strong locking force. This structure includes at least one clamping plate 41, preferably two clamping plates 41 connected by a longitudinal support plate 42. Guide grooves 221 are provided on both sides of the inner wall of the clamp 2, and guide protrusions 411 that mate with the guide grooves 221 are provided on the outer wall of the clamping plate 41, ensuring that the clamping plate 41 can be accurately and smoothly inserted into the installation gap 22. A pin hole 413 is provided on the clamping plate 41 for additional pin locking. Handles 412 are symmetrically provided at the upper and lower ends of the clamping plate 41 for easy construction operation.

[0030] The attachment frame 5 is a standard accessory for tower cranes, used to hold the standard sections of the tower crane body. The attachment tie rod 6 is usually an adjustable tie rod with spherical bearings or connecting lugs at both ends. Its upper end is hinged to the attachment frame 5, and its lower end is hinged to the connecting lug 13 on the crossbeam 1 via a pin.

[0031] Working principle Before hoisting, the cross-sectional dimensions of the target H-beam steel column 3 were accurately measured on site. Based on the measurement results, standard steel plates 21 of appropriate specifications and quantity were selected. In the ground work area, the selected steel plates 21 were assembled into two clamps 2 that matched the dimensions of the column 3 using high-strength bolts. Then, the two ends of the crossbeam 1 were pre-connected to these two clamps 2 using high-strength bolts to form a complete rigid frame module.

[0032] Using a lifting device, hook the lifting lug 11 on the crossbeam 1 to lift the pre-assembled frame module as a whole and move it to the predetermined installation height of the H-beam column 3. Adjust the frame position, and if the pin hole 211 on the clamp 2 is aligned with the existing process hole on the column 3, insert the pin to achieve initial positioning.

[0033] Align the guide protrusion 411 of the clamping plate 41 with the guide groove 221 on the inner wall of the clamp 2, and strike the handle 412 with a sledgehammer to forcefully drive the clamping plate 41 into the installation gap 22 between the clamp 2 and the flange of the H-beam steel column 3. Then, insert a high-strength bolt through the hole in the clamping plate 41 and securely connect it to the column 3. If necessary, an additional locking pin can be inserted through the pin hole 413.

[0034] Finally, the attachment frame 5 is installed and secured to the tower crane body. Then, the upper end of the attachment rod 6 is connected to the attachment frame 5, and the lower end is connected to the connecting lugs 13 at both ends of the crossbeam 1 via pins. By adjusting the length of the attachment rod 6 to make it taut, the entire attachment installation is finally completed.

[0035] The disassembly process is the reverse of the above steps, and all connections are detachable mechanical connections. After disassembly, all standard steel plate parts 21, crossbeams 1, fasteners, etc., can be sorted and recycled, and transported to the next construction site for reuse.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
