And the stability and the safety of combined hoisting of the rear wall enclosure superheater are effectively improved.

Description

Technical Field

[0001] This utility model relates to the field of electromechanical hoisting technology, specifically a hoisting truss for rear wall superheater assembly. Background Technology

[0002] Because the high-temperature reheater is located between the suspension tubes and convection tube bundle of the intermediate header of the rear wall superheater, and intersects with the convection tube bundle, if the entire convection tube bundle is assembled, the high-temperature reheater assembly cannot be positioned. Even single-piece installation is very difficult. The installation schemes for these two components are closely related and should be solved in coordination. However, the shape of the rear wall superheater assembly is abnormal, making it difficult to place a lifting and reinforcing frame on top of the assembly. Deformation is likely to occur when lifting and straightening it.

[0003] Therefore, a lifting truss for the rear wall superheater assembly is needed to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting truss for the assembly of a rear-mounted superheater wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting truss for a rear wall superheater assembly includes a dual-purpose truss. The top of the dual-purpose truss is fitted with a connection end to the lower header of the rear wall superheater, and the bottom of the dual-purpose truss is fitted with a truss slewing pin foundation. A temporary pin mechanism is provided between the lower header connection end of the rear wall superheater and the dual-purpose truss. A truss slewing pin is provided between the dual-purpose truss and the truss slewing pin foundation. The dual-purpose truss and the truss slewing pin foundation rotate around the truss slewing pin foundation. When the dual-purpose truss and the truss slewing pin foundation rotate to a near-vertical state, the truss slewing pin between the dual-purpose truss and the truss slewing pin foundation is removed. Lifting the dual-purpose truss allows the truss slewing pin foundation to detach from the dual-purpose truss. After the second connecting block is loosened, the dual-purpose truss is lowered to the ground, effectively improving the stability and safety of the rear wall superheater assembly lifting.

[0007] As a preferred embodiment of this utility model, the top of the dual-purpose truss is fixedly connected to a first connecting block, and a temporary pin between the component and the dual-purpose frame is fixedly connected to one side of the first connecting block.

[0008] As a preferred embodiment of this utility model, a second connecting block is fixedly connected to one side of the lower header connection end of the rear wall superheater. The second connecting block has a strip-shaped elongated hole inside, and the temporary pin between the component and the dual-purpose frame is inserted into the inside of the strip-shaped elongated hole for rotation.

[0009] As a preferred embodiment of this utility model, the truss slewing pin passes through the top fixed end of the truss slewing pin foundation and the fixed end on one side of the dual-purpose truss, with the two fixed ends fitting together, and the truss slewing pin rotates inside the two fixed ends.

[0010] As a preferred embodiment of this utility model, the temporary pin between the component and the dual-purpose frame can be inserted into the interior of the elongated slot and slide.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, when the dual-purpose truss and the truss slewing pin foundation rotate to a near-vertical state, the truss slewing pin between the dual-purpose truss and the truss slewing pin foundation is removed. Lifting the dual-purpose truss will disengage the truss slewing pin foundation from the dual-purpose truss. After the second connecting block is loosened, the dual-purpose truss can be lowered to the ground, effectively improving the stability and safety of the rear wall superheater assembly hoisting.
