Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting construction support technology, specifically to a hoisting device for large-scale pipe screen equipment. Background Technology
[0002] Large tube panels are a crucial component widely used in large power plant boilers, especially in applications requiring the handling of large amounts of heat and steam, such as coal-fired power plants. The installation of large tube panels is a complex and delicate process involving multiple steps and technical aspects to ensure safe and precise placement in the designated location. Due to the complex shape of the object being lifted, direct lifting with slings results in poor stability and is prone to accidents. Therefore, a stable lifting device is urgently needed. Utility Model Content
[0003] The present invention aims to provide a hanging device for large-scale tubular screen equipment to solve the problem of poor stability and easy safety accidents when using slings to directly hoist large-scale tubular screens.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hanging device for a large tube screen, including a connecting plate, wherein a main ear plate perpendicular to the connecting plate is fixedly connected to the upper surface of the connecting plate, and the main ear plate is provided with a plurality of transverse openings;
[0005] The lower surface of the connecting plate is fixedly connected to a main lug plate two perpendicular to the connecting plate. The main lug plate two is also provided with two openings. The lower surface of the connecting plate is fixedly connected to two secondary lug plates. The two secondary lug plates are located on both sides of the main lug plate two and are parallel to the main lug plate two. The main lug plate two and the two secondary lug plates are provided with through holes. The central axis of the three through holes is coaxial. The same bolt is detachably connected to the three through holes.
[0006] Furthermore, there are two openings on the main ear plate, both of which are at the same horizontal height and are located near the left and right ends of the main ear plate.
[0007] Furthermore, vertical stiffening plates are fixedly connected to both sides of the main ear plate, and the stiffening plates are perpendicular to the connecting plate and to the upper surface of the connecting plate.
[0008] Furthermore, the three through holes are elliptical in shape.
[0009] Furthermore, the height of the two secondary ear plates is lower than the height of the second primary ear plate.
[0010] Furthermore, the top corners of the first main ear plate, the second main ear plate, and the two secondary ear plates are all rounded.
[0011] Furthermore, it also includes an auxiliary plate, which has three clearance holes for the main ear plate and two secondary ear plates to pass through.
[0012] The working principle of this utility model is as follows: During the hoisting of large tube-type components, multiple hoisting devices as described in this solution are prepared. The main lug plate and two secondary lug plates of the hoisting device are passed through the tube-type component through the temporary opening. The clearance hole of the auxiliary plate is aligned with the main lug plate and the two secondary lug plates and inserted until the surface of the auxiliary plate contacts the surface of the tube-type component. Then, bolts are inserted into the three through holes so that the bolts abut against the auxiliary plate, and the bolts are fixed in the through holes with nuts. At this time, the installation of the hoisting device is completed. Multiple hoisting ropes are passed through the four openings of different hoisting devices for hoisting.
[0013] The beneficial effects of this utility model are:
[0014] 1. This solution uses connecting plates and auxiliary plates to fix the tube panel. This design effectively limits the damage caused by shaking of the tube panel during hoisting, improves stability, and thus increases safety.
[0015] 2. The two openings on the main ear plate one and the main ear plate two for the suspension rope to pass through can effectively reduce the stress on a single suspension rope, thereby improving the safety factor.
[0016] 3. The stiffening plate between the connecting plate and the main ear plate can significantly improve the rigidity of the hanging device and effectively prevent safety accidents caused by damage to the hanging device due to excessive weight of the tube screen components.
[0017] 4. The top corners of the main ear plate 2 and the two secondary ear plates are rounded, and the height of the two secondary ear plates is lower than that of the main ear plate 2, which makes it easy to insert into the temporary opening of the tube screen and improves the convenience of insertion.
