Problems solved by technology

[0002] At present, the superheater of the biomass furnace often involves the installation of a large number of serpentine tube panels. The serpentine tube panel has the characteristics of large plane size, poor rigidity, and easy deformation. It is inconvenient to use, and the connection stability with the whole serpentine tube screen is not good, and the serpentine tube is often deformed during the hoisting process, causing serious damage to the quality of the serpentine tube, which leads to the failure of the installation process to proceed smoothly, and cannot guarantee subsequent Usage requirements

Abstract

The invention relates to the field of serpentine pipe screen installation, and discloses an adjustable hoisting device of a serpentine pipe screen and a hoisting method thereof. The pipe screen comprises a plurality of straight pipes, a plurality of elbows, a left vertical beam, a right vertical beam, an upper cross beam and a lower cross beam, the left vertical beams and the right vertical beamsare fixedly connected into a rectangular frame, and lifting lugs are arranged at the top ends of the vertical beams; the vertical beams are rectangular steels, guide grooves in the length direction are formed in the front end plates of the vertical beams, horizontal supporting rods are arranged in the guide grooves, the rear ends of the horizontal supporting rods are provided with bottom plates and extend into the vertical beams, the bottom plates are in contact with the rear end plates, and a plurality of adjusting holes are formed in side end plates along the length direction; butt joint holes are formed in the horizontal supporting rods, the adjusting holes and the butt joint holes are connected through bolts, and the horizontal supporting rods can be in contact with the straight pipesand vertically support; and limiting rods are arranged at the front ends of the horizontal supporting rods, the limiting rods are used for being in contact with the straight pipes and is horizontallylimited. According to the adjustable hoisting device of the serpentine pipe screen and the hoisting method thereof, a whole screen pipe screen can be connected, the large-size pipe screen can be stably hoisted, so that the quality of the pipe screen is good, deformation is prevented, and the distance change between the adjacent straight pipes can be effectively adapted.

Description

technical field [0001] The invention relates to the technical field of installation of a serpentine tube panel, in particular to an adjustable hoisting device for a serpentine tube panel and a hoisting method thereof. Background technique [0002] At present, the superheater of the biomass furnace often involves the installation of a large number of serpentine tube panels. The serpentine tube panels have the characteristics of large plane size, poor rigidity, and easy deformation. It is inconvenient to use, and the connection stability with the whole serpentine tube screen is not good, and the serpentine tube is often deformed during the hoisting process, causing serious damage to the quality of the serpentine tube, resulting in the failure of the installation process to proceed smoothly, and the subsequent Usage requirements. [0003] Therefore, this application proposes an adjustable hoisting device for a serpentine tube panel and its hoisting method, which can be stably ...
