Description

Technical Field

[0001] This utility model relates to the field of crane support clamp technology, and in particular to an anti-detachment ring clamp. Background Technology

[0002] Tower cranes used in super high-rise core tube frame structures are mostly internal climbing or externally mounted, with a few using externally attached types due to the size or complexity of the core tube. Externally attached tower cranes need to be located outside the frame, and their attachment is mostly on the frame columns. The frame columns are permanent structures, and the design unit usually does not allow direct welding of the tower crane attachment base on them. In this case, the attachment base can only be a clamp type. After the ring clamp is installed, due to the machining precision, the clamp and the steel column cannot be completely fitted, leaving gaps. The clamp is prone to slipping and falling off. Currently, most practices are to weld a steel plate under the clamp to support it. This method requires welding operations for each installation, increasing manpower input and resulting in poor economic efficiency. At the same time, there is also a small area of ​​hot work welding on the frame column. Afterwards, it is necessary to cut off the supporting steel plate, grind, and apply anti-corrosion coating, which is also economical and inefficient. Therefore, it is necessary to design a ring clamp that prevents falling off. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-detachment ring clamp to solve the problem that existing ring clamps, due to insufficient machining precision, cannot be completely fitted to the steel column after installation, leaving gaps, making the clamp easy to slip and fall off. The current practice is to weld a steel plate under the clamp to support it. This method requires welding for each installation, increasing manpower and making it uneconomical. At the same time, there is also a small area of ​​hot welding on the frame column, which requires subsequent processes such as cutting off the supporting steel plate, grinding, and applying anti-corrosion coating, resulting in poor economy and efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ring-shaped clamp for preventing detachment, comprising a first half-clamp, a second half-clamp, a first connecting plate, a second connecting plate, a fixing bolt, a fixing nut, a first outer plate, a first inner plate, a first locking nut, a first locking bolt, a second outer plate, a second inner plate, a second locking nut, a second locking bolt, a first reinforcing plate, a connecting plate, a reinforcing rib, and a second reinforcing plate. The first half-clamp is tightly attached to the second half-clamp, and the first and second half-clamps are symmetrically provided with a first connecting plate and a second connecting plate, respectively. A fixing bolt is sleeved in a through groove symmetrically opened on the first and second connecting plates. A fixing nut is connected to the fixing bolt by a threaded engagement, and the fixing nut is tightly pressed against the second connecting plate. The bottom of the first half-clamp is symmetrically provided with a first outer plate and a first inner plate, respectively. A first locking nut is provided on the first outer plate, and a first locking bolt is connected to the first locking nut by a threaded engagement. One end of the first locking bolt is sleeved in a through hole opened in the first inner plate.

[0005] As a further technical solution of this utility model, the bottom of the second half hoop is symmetrically provided with a second outer side plate and a second inner side plate, and a second locking nut is provided on the second outer side plate.

[0006] As a further technical solution of this utility model, the second locking nut is connected to a second locking bolt by a threaded connection, and one end of the second locking bolt is sleeved in a through hole opened in the second inner side plate.

[0007] As a further technical solution of this utility model, a first reinforcing plate is provided on the side wall of the first half hoop, and connecting plates are symmetrically connected to the first half hoop.

[0008] As a further technical solution of this utility model, the connecting plate is located between the first reinforcing plates.

[0009] As a further technical solution of this utility model, a reinforcing rib is provided at the connection between the connecting plate and the first half hoop.

[0010] As a further technical solution of this utility model, a second reinforcing plate is symmetrically arranged on the side wall of the second half hoop.

[0011] This utility model provides an anti-slip ring clamp, the advantages of which are: by the mutual cooperation of the fixing bolt and the fixing nut, the first and second mating plates on the first and second half clamps are locked together to complete the clamp installation process. Then, the first and second locking bolts, which serve as the top block bolts, are rotated and retracted into the first and second inner side plates under the threaded engagement of the first and second locking nuts, thus completing the locking and preventing relative sliding between the clamp and the steel column due to gaps. This completely eliminates the need for hot welding when connecting the clamp and the steel column, avoiding the need for subsequent processing of the steel column, and providing good safety performance. It greatly improves the safety, economy, and practicality of the ring clamp using the top block to prevent slippage. Attached Figure Description
