Embodiment 1

[0035] The serpentine tube of the CDQ boiler economizer of the present invention is installed in place, and includes a rail, a pulley hanger, a chain hoist 7 and a diamond-shaped bracket 2 .

[0036] see now figure 1 and figure 2 , figure 1 It is a schematic structural diagram of the serpentine tube in the embodiment of the present invention being clamped in a diamond-shaped bracket, figure 2 It is a schematic diagram of the use state of the serpentine tube in-position spreader according to the embodiment of the present invention. As shown in the figure, the track is a section of I-beam 4, and the I-beam is horizontally erected above the installation position of the serpentine tube of the economizer of the CDQ boiler.

[0037] The pulley hanger is provided with two side plates 12, the upper parts of the two side plates are each provided with two pulleys 3, the middle parts of the two side plates are horizontally connected to each other by solid welding, and the lower part...

Embodiment 2

[0040] A method for using a spreader for installing an economizer serpentine tube in a CDQ boiler, which is characterized by comprising the following steps:

[0041] a. The track is stably and firmly erected horizontally above the installation position of the economizer serpentine tube of the CDQ boiler, which is convenient for hoisting the economizer serpentine tube and moving the economizer serpentine tube on the track;

[0042] b. The serpentine tube of the economizer of the CDQ boiler is installed in place. The spreader itself is installed. After the pulley hanger, the chain hoist and the sling are connected, the two pulley hangers are matched with each other and are installed on the I-beam. 4 on;

[0043] c. Use two diamond-shaped brackets to be movably clamped at both ends of the serpentine tube, so that the two pulley hangers cooperate with each other to lift the diamond-shaped bracket with a hand chain hoist, and the third hook below the hand chain hoist hangs the snak...

Abstract

The invention relates to a coke dry quenching boiler economizer serpentine pipe in-place installation lifting device, which comprises a rail, a pulley lifting frame, hand chain hoists (7) and diamond brackets (2), wherein the rail is a section of a steel I-beam (4), the steel I-beam is horizontally arranged above a coke dry quenching boiler economizer serpentine pipe installation position, the pulley lifting frame is provided with two side plates (12), the upper portions of the two side plates are respectively provided with two pulleys (3), the first lifting hook (6) of the hand chain hoist (7) is hooked in the hook shaft (5) of the pulley lifting frame, a second lifting hook (8) is connected to one end of a lifting cable, the other end of the lifting cable is connected to a third lifting hook (10) through a fixation ring, and the third lifting hook (10) is movably connected to the diamond bracket (2) in a clamped manner. According to the present invention, the coke dry quenching boiler economizer serpentine pipe in-place installation lifting device has advantages of simple structure, convenient production, good lifting safety, construction efficiency improving and engineering cost reducing, can prevent the serpentine pipe from inverse running damage, and can avoid work delaying, time delaying and material loss.

Description

technical field [0001] The invention relates to a spreader, in particular to a spreader for installing a serpentine tube of an economizer of a CDQ boiler and a method for using the same. Background technique [0002] The economizer is a device installed at the lower part of the flue at the tail of the boiler to recover waste heat. It consists of horizontally arranged parallel elbow pipes (commonly known as serpentine pipes). [0003] Due to the complex structure of the serpentine pipe, the heavy weight, and the complicated equipment around the economizer, the conventional method of hoisting will increase the workload of dismantling and restoration, which brings difficulties to the installation. [0004] Therefore, the installation of the coiled pipe of the economizer of the known CDQ boiler has the above-mentioned inconveniences and problems. SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to propose a hoisting tool for installing the serpentine ...
