Embodiment Construction
[0011] As shown in the figure, a crane for disassembling the flare head is arranged on the top of the steel structure of the flare tower. The crane is lifted to the height when it is in working condition; the support frame 9 fixed on the bracket 10 that is fixed on the bracket 10 that is fixed on the bottom of the crane tower body 3 is connected with bolts to realize the tower body crane. Fix the tower body 3 in the vertical direction; then, install the hoop 7 at the designated position of the crane tower body 3; Cooperate and pull, complete the rotation of the crane and put it in place, so that the shoulder pole beam 1 is directly above the hoisted flare head. Lower the pole beam 1 to a height that can be connected to the flare head through another wire rope drawn from the ground winch and pass through the crane head 2 and the tower body 3. After the connection is completed, use the wire rope to lift the flare head. Through the cooperative pulling of the fairy gourd and the ...

The invention discloses a crane mounted at the top part of a flare tower and used for disassembling a flare head. The crane comprises a crane tower body; a crane head part is arranged at the top part of the crane tower body. The crane is characterized in that a pulley is arranged at the crane head part; a carrying pole is connected with the pulley by a steel wire rope; a spherical hinge is welded at the bottom part of the crane tower body and is connected with a spherical hinge support; and a pulling rod is arranged between the crane head part and the crane tower body. The crane mounted at the top part of the flare tower and used for disassembling the flare head has the advantages of simple structure and convenience in use, can directly disassemble the flare head to be maintained, and can automatically descend in order to avoid a high-temperature area, so large hoisting machines are not needed, the difficulty in selecting the model of the large hoisting machine can be avoided, and the operating cost of equipment can be saved.
Description
technical field [0001] The invention belongs to a crane installed on the top of a flare tower for disassembling and assembling a flare head, in particular to a liftable crane installed on the top of a flare tower for disassembling and assembling a flare head in petrochemical and oil refining industries. Background technique [0002] In the process of petrochemical refining, in order to ensure normal production, it is necessary to discharge corresponding exhaust gas. The exhaust gas is transported through pipelines to the combustion flare attached to the flare tower tower, and is burned through the combustion flare installed in the combustion flare head (hereinafter referred to as the flare head). burn in the device. The torch head needs to be disassembled for inspection, replacement, and reinstallation on a regular basis. The petrochemical flare tower is generally tens of meters high, or even more than a hundred meters high. The flare head is generally disassembled by large...
