Description

Core unit dismouting auxiliary device

Technical Field

The utility model relates to the technical field of a core unit dismounting scheme of a gas power generation water heater, in particular to an auxiliary device for dismounting a core unit of a (distributed energy) gas power generation water heater.

Background

On the Federation of the United nations, 9 and 22 months in 2020, the national chairman Xi jinping announces that: china will improve the autonomous contribution of the country, adopt more powerful policies and measures, strive for carbon dioxide emission to reach the peak value 2030 years ago, strive for carbon neutralization 2060 years ago. "the policy is issued by national administration and part provinces and cities in 2020, and the development of the distributed energy industry is brought into key work of energy field system reformation. All over the world, distributed energy projects are also definitely proposed and encouraged in policies such as energy conservation and emission reduction, air pollution prevention and the like, and the advantages of cleanness, high efficiency, low emission and the like are fully exerted to cooperate with the healthy and orderly development of air pollution prevention and clean heat supply. The adjustment of the national macro policy brings opportunities for the development of the aerospace gas power generation water heater, and the pressure of core unit maintenance is rapidly increased along with the increase of the target capacity. Originally as long as generator or engine go out the problem and just wholly remove the outer frame of box, again with the whole handling of core unit out the mode of overhauing unable the needs that satisfy production, consequently urgent need a convenient core unit dismouting auxiliary device.

Disclosure of Invention

The utility model aims to provide an auxiliary device for dismounting a core unit, which meets the requirements of convenience and quickness in generator or engine overhaul. Compared with the existing core unit dismounting mode, the core unit dismounting mode has the advantages that the whole operation process is simplified, and the dismounting is more convenient and efficient during the overhaul of the generator or the engine. Overcomes the defects in the prior art.

In order to achieve the purpose, the technical scheme of the utility model is as follows: a cross beam is arranged on the lower portion of the core unit, a sliding rail is formed on the upper portion of the cross beam, a sliding block matched with the sliding rail is arranged on the upper portion of the cross beam, a plane needle roller bearing is arranged at the position of the sliding block, supporting plates are arranged on two sides of the core unit respectively and are of an L-shaped structure, each supporting plate is composed of a horizontal mounting plate and a longitudinal mounting plate, the horizontal mounting plates and the longitudinal mounting plates are perpendicular to each other and are distributed, the side wall of the core unit is connected with the longitudinal mounting plates through connecting bolts, a longitudinally-distributed supporting bolt is arranged at the position of each horizontal mounting plate, and the lower end of each supporting bolt abuts against the plane needle roller bearing.

The utility model discloses a core unit dismounting auxiliary device, which has the beneficial effects that: compared with the prior art, the lifting device has the advantages of simple layout, simplicity and convenience in installation, time and labor conservation in later-stage maintenance of the core unit, and obvious reduction of lifting requirements on a construction site.

And (3) improved comparison: the generator and the engine of gas power generation hot water machine core unit all are the single foot, and the generator footing is located the intermediate position, can rely on self footing to stand steadily, but the footing of engine is close to the tip, and the other end bottom sets up the unable bearing of oil tank (oil tank), can't be at the other end installation footing, therefore the engine can't rely on self footing to stand steadily, in case the generator loosens with the linking bolt of engine, the engine will be toppled over to the one end that does not have the footing.

At present, when a generator or an engine is maintained, cooling liquid in a unit is emptied, then a wire harness, a connecting hose, a water tank, a silencer, a plate-arranging pipe assembly, a three-way catalytic casting and the like are removed, then an outer frame is removed, finally the whole core unit is hoisted to a special platform, and then bolts for connecting the generator and the engine are all loosened for maintenance. All accessories in the whole maintenance process basically need to be dismantled and then reinstalled, so that the time is consumed, and the lifting of the whole core unit also puts a very high requirement on the lifting capacity of the site.

The novel scheme utilizes this auxiliary device with the engine jacking, makes its atress. Then the fixing bolt between the engine and the generator is removed, the engine and the generator are separated by a jackscrew, and the generator or the engine can be moved out by a lifting vehicle.

Detailed Description

The utility model will be further described with reference to the accompanying drawings.

The utility model discloses a core unit dismounting auxiliary device, which is different from the prior art in that: the core unit comprises a core unit 6 and is characterized in that a cross beam 5 is arranged on the lower portion of the core unit 6, a slide rail is formed on the upper portion of the cross beam 5, a slide block 3 matched with the slide rail is arranged on the upper portion of the cross beam 5, a plane needle roller bearing 4 is arranged at the position of the slide block 3, supporting plates 1 are respectively arranged on two sides of the core unit 6, the supporting plates 1 are of L-shaped structures, each supporting plate 1 is composed of a horizontal mounting plate 7 and a longitudinal mounting plate 8, the horizontal mounting plates 7 and the longitudinal mounting plates 8 are mutually perpendicular to each other, the side wall of the core unit 6 is connected with the longitudinal mounting plates 8 through connecting bolts 9, a supporting bolt 2 is longitudinally distributed at the position of the horizontal mounting plate 7, and the lower end of the supporting bolt 2 abuts against the plane needle roller bearing 4. The sliding block 3 can move along the sliding rail, the positions of the plane needle bearing 4 and the supporting bolt 2 are adjusted, the bottom of the supporting bolt 2 is just positioned in the plane needle bearing hole, the supporting bolt 2 is screwed to stress the bolt, and the end part (close to the generator) of the engine is supported by the core unit dismounting auxiliary device. And then the connecting bolt of the generator and the engine is removed, and the generator and the engine are separated by using the jackscrew.

In specific implementation, a protective rubber ring is sleeved at the joint of the planar needle bearing 4 and the end of the support bolt 2.

Only need when overhauing the generator with the coolant liquid evacuation and demolish ternary catalysis and tubulation subassembly earlier, demolish the tubulation support and the ECU of generator air inlet cover and engine side again, then utilize this novel auxiliary device to prop the engine, demolish connecting bolt between generator disc and the engine flywheel and the connecting bolt between generator and the engine housing after that, then loosen generator footing fixing bolt, the reuse jackscrew separates both, shift out the generator from the box tip with the lift truck at last. And after the maintenance is finished, the generator is installed in the original position by using the lifting vehicle, and finally the accessories are installed.

When the engine is overhauled, the generator is moved out of the box body from the end part according to the step of removing the generator (an operation space is reserved for the displacement of a subsequent engine), then the water pump and the connecting hose of the liquid inlet and the liquid outlet of the engine cooling liquid are removed, then the hose of the oil pan of the engine is removed, then the air filter is removed to the connecting hose between the proportioners, then the wiring plug of each electronic component of the engine is pulled out, and finally the engine is moved out of the side face of the box body by using a lifting vehicle after the starting motor switch and the engine foot fixing bolt are removed. And after the maintenance is finished, the engine and the generator are sequentially installed in the original position by the lift truck, and finally the accessories are installed.
