Embodiment 1

[0048] The special hoisting device for replacing the heat exchange tubes of the horizontal tube cooler of the present invention sets up a heat exchange tube removal platform (not shown in the figure) on the side edge of the horizontal tube cooler, and sets lifting lugs on the top of the horizontal tube cooler, including manpower word mast, two mast swivel bearings and hoist.

[0049] see now figure 1 and figure 2 , figure 1 It is a schematic diagram of the structure of a gable mast according to an embodiment of the present invention, figure 2 for figure 1 side view. As shown in the figure, the herringbone mast 7 is formed in a herringbone shape by two mast columns 71, the mast columns are steel pipes, the top of which is provided with a first lug 75 and a second lug 76, and the middle is provided with a third lug 77 , the two bottom ends are respectively provided with a rotating ear seat 78, and the rotating ear seat is provided with a rotating ear seat hole 79; two par...

Embodiment 2

[0054] A method for using a special hoisting device for replacing heat exchange tubes of a horizontal tube cooler, comprising the following steps:

[0055] a. Make and install the special hoisting device for replacing the heat exchange tubes of the horizontal tube cooler

[0056] The spreader is designed by referring to the lifting principle of the mast crane. The special lifting device is composed of a herringbone mast, a chain block, a support, a winch, a lifting pulley, a counterweight, and a lifting wire rope. The hoist is used as the lifting part of the special hoisting device, the mast is used as the guide support of the hoisting tool, and the pulley is used as the guide of the hoisting wire rope;

[0057] b. Install a special hoisting device at the replacement site of the heat exchange tube of the horizontal tube cooler

[0058] The herringbone mast is fixed on the top of the cross tube cooler through the two mast rotating supports made, and the pitch angle a of the he...

Abstract

The invention relates to a special lifting device for replacing a heat exchange tube of a horizontal water-tube cooler. The special lifting device comprises a herringbone mast, two mast rotating support seats and a windlass. The special lifting device is characterized in that the herringbone mast is formed by two mast upright posts, each mast rotating support seat (9) comprises a support seat bottom plate (91) and two vertical plates (92), through holes (93) are formed in the centers of the two vertical plates (92), the two mast rotating support seats (9) are welded at the edge of the tower top of the horizontal water-tube cooler, a chain block (8) is arranged between a lifting lug (11) which is arranged on the top, and a first lifting lug (75) of the herringbone mast, the windlass (4) is arranged on the ground, and a steel wire rope of the windlass is ultimately connected with a lifting steel wire rope group (6) by virtue of three hoisting pulleys so as to form the special lifting device for replacing the heat exchange tube of the horizontal water-tube cooler. The special lifting device has the advantages that the structure is simple, the manufacturing is convenient, the defects of a traditional lifting mode for replacing the heat exchange tube of the horizontal water-tube cooler are overcome, the cost is reduced, and the lifting safety of the heat exchange tube is increased.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a special hoisting device for replacing heat exchange tubes of a horizontal tube cooler and a usage method thereof. Background technique [0002] The horizontal tube cooler is the main equipment in the gas purification area of ​​the coking plant. It is used for cooling the gas. After a certain period of operation, the internal heat exchange tube needs to be replaced. The quantity is large (generally thousands of pieces), the location is high, and the operating space is small (the erected scaffolding affects the hoisting). This hoisting method is not economical and safe. [0003] Therefore, there are above-mentioned various inconveniences and problems in the known mode of using a car crane to hoist the heat exchange tubes. Contents of the invention [0004] The object of the present invention is to propose a safe and reliable special hoisting device for replacing the heat exchange tubes of ...
