6) installing a medium pipe on the fire cleaner vertical distributor to be overhauled or replaced, and checking the medium pipe to catch leakage;
7) and (5S) work is well done, and linkage test run operation is carried out on the fire cleaning machine.
The disassembly and assembly method for the vertical distributor of the fire cleaning machine is applied to an on-line replacement and maintenance project of the vertical distributor of the fire cleaning machine, can greatly shorten the construction period under the condition of ensuring the quality and the safety, ensures the construction safety, saves the labor cost, and has good economic benefit and social benefit. The dismounting and mounting method for the vertical distributor of the fire cleaning machine, provided by the embodiment, can shorten the overhaul working hours of 4 hours to 2 hours in practical application, ensures the construction safety and creates considerable economic benefits.
As shown in fig. 3, as an example, in step 2), the fixing direction of the "U" -shaped tray 2 is opposite to the hanging direction of the weight block 3. This is suitable for the removal and installation of the upper vertical distributor 5 of the fire-fighting machine. Preferably, before aligning the "U" shaped tray 2 right below the upper vertical distributor 5 and fixing the "U" shaped tray 2 with the upper vertical distributor by the locking bolt 4 in step 4), the method further comprises the steps of firstly hanging the chain block and the wire rope on the middle lifting lug 10 and the first end lifting lug 10 of the balance beam respectively, and enabling the "U" shaped tray 2 to incline upwards along the horizontal direction; the alignment of the "U" shaped tray 2 directly below the upper vertical distributor 5 and the securing thereof by the locking bolts 4 also includes the loosening of the wire rope at the first end ear 10. The reason for tilting the "U" -shaped pallet upwards in the horizontal direction before fixing is to reduce the impact of the upper vertical distributor 5 on the "U" -shaped pallet, resulting in unbalance of the two ends of the balance beam, and when the upper vertical distributor 5 is fixed to the "U" -shaped pallet, the balance is established at the two ends of the balance beam, so that the wire rope can be loosened. More preferably, the angle of the upward inclination of the "U" -shaped tray 2 in the horizontal direction is between 5 ° and 10 °.
As shown in fig. 4, as an example, in step 2), the fixing direction of the "U" -shaped tray 2 is the same as the hanging direction of the weight block 3. This case is suitable for the removal and installation of the lower vertical distributor 6 of the fire-cleaning machine, preferably, when the "U" -shaped tray 2 is aligned directly above the lower vertical distributor 6 in step 4) and fixed thereto by means of the locking bolts 4, the locking bolts 4 are locked in the mounting holes on the vertical distributor by means of the through holes 20 to a depth of between 2cm and 3 cm.
As an example, step 1) construction preparation further comprises the step of inspecting and mapping the spare parts. The spare parts refer to the whole structure of the vertical distributor body to be replaced, and the problem of replacement and installation errors can be effectively prevented by carrying out inspection and mapping on the structure of the vertical distributor body to be replaced.
As an example, after the medium pipe is removed in the step 3), corresponding marks are made on the medium pipe and the installation position of the medium pipe, and in the step 6), the medium pipe is installed in a one-to-one correspondence mode according to the marks, so that the installation position of the medium pipe can be quickly positioned, and the work efficiency is improved.
In summary, according to the fire cleaning machine vertical distributor dismounting device and the dismounting method thereof, the balance beam is arranged, the U-shaped tray arranged on the balance beam is used for bearing the vertical distributor, and after the vertical distributor is separated from the fire cleaning machine body, the chain block arranged in the middle of the balance beam slides out along the sliding track of the fire cleaning machine, so that the vertical distributor is driven to directly slide out from the mounting position, and the vertical distributor is dismounted and lifted away from the mounting position; correspondingly, when the vertical distributor is installed, the vertical distributor is fixed on the U-shaped tray, and then the vertical distributor is made to slide to an installation position along a sliding track of the ignition cleaner through a chain block in the middle of the balance beam, so that the installation of the vertical distributor is realized. Regardless of being disassembled or assembled, the disassembling and assembling equipment does not need a plurality of people to move the vertical distributor from the installation position to the position below the sliding track of the fire cleaning machine or from the position below the sliding track of the fire cleaning machine to the installation position, so that the overhauling construction period time is effectively shortened, and the labor efficiency and the construction safety coefficient are improved.
