Embodiment 1

[0024] See Figure 1-3 , A construction method for installing and removing the coke tank cover from the CDQ hoist frame by using a temporary trolley, which includes the following steps:

[0025] (a) Pre-make a temporary trolley with the same span as the coke truck track, and place the temporary trolley on the traction platform or the coke tank inspection platform. The temporary trolley includes a frame 1 with a horizontal support frame inside the frame 4. The number of horizontal support frames can be set according to needs. Support feet 2 are symmetrically provided on both sides of the lower part of the frame, and there are at least two support feet on each side, and walking wheels 3 are provided under each support foot;

[0026] (b) Transport the temporary trolley to the coke-transporting vehicle track by using the traction mechanism, the pulling platform and the coke transporter at the coke tank maintenance platform;

[0027] (c) When installing the coke tank cover, first use a c...

Abstract

The invention relates to a construction method for installing and dismantling a coke jar cover from the drill tower of a dry quenched coke hoist by using a temporary trolley. The method comprises the following steps: manufacturing a temporary trolley with the same span of a coke car rail in advance, placing the temporary trolley below the drill tower of the hoist; during installation, placing a new coke jar cover on the temporary trolley in advance, using the coke car to pull the temporary trolley below the drill tower of the hoist, using the hoist to hang the coke jar cover to an installation location, and placing all the connection parts of the coke jar cover in position to finish installation; and the dismantling method of the coke jar cover comprises the following steps: using the hoist to hang the coke jar cover to place stably on the temporary trolley after dismantling all the parts connected with the coke jar cover, and using the coke car to push the temporary trolley out of the drill tower and finish the dismantlement of the coke jar cover. The invention is convenient to operate, saves time and labour and has high safety.

Description

Technical field [0001] The invention relates to a method for installing and overhauling coke dry quenching system equipment in the coking industry, in particular to a construction method for installing and removing a coke tank cover from a dry quenching hoist derrick using a temporary trolley. Background technique [0002] At present, with the development of the coking industry, CDQ systems are widely used due to their environmental protection and energy saving features. In the process of equipment installation and maintenance, the commonly used CDQ system coke tank cover installation and removal method is to use cranes, hoists, hoists, and use the method of transfer to transfer the coke tank cover from the hoist derrick to the derrick. Inside or from inside the derrick to outside the derrick. However, because this method often needs to be transported multiple times, there are problems such as long construction time, high labor intensity, and low maintenance efficiency, and it i...
