Description

Lifting position for installing central air conditioner

Technical Field

The utility model relates to an air conditioner mounting tool field, the position of lifting that a central air conditioning installation was used very much.

Background

The outer machine of the central air conditioner is large in appearance, during installation, the outer machine shell of the central air conditioner is installed on the ground through the fixing plates and the foot screws on the left side and the right side of the lower end, when the outer machine is installed, the horizontal position cannot meet the requirement, and due to the fact that the compressor of the outer machine is in an inclined state, vibration generated by the compressor or other moving parts of the outer machine can be amplified during work, so that the working noise of the whole machine is large, and the service lives of the compressor and other parts of the outer machine can be influenced to a certain extent in the.

When the existing central air conditioner outdoor unit is installed on the ground (such as a roof and the like) through a foundation screw, the central air conditioner outdoor unit needs to be ensured to be in a horizontal state as much as possible after being installed, because the central air conditioner outdoor unit is installed in a mode of fixing the foundation screw, after the fixing plate holes in the left side and the right side of the lower end of the outdoor unit are sleeved in the foundation screw, if the levelness of the outdoor unit cannot meet the requirement, the problem is usually solved by increasing or decreasing gaskets between the lower end of the fixing plate and the foundation screw, because the increasing or decreasing of the gaskets needs to take the fixing plates in the left side and the right side of the air conditioner outdoor unit down from the foundation screw again, and then after the gaskets are increased or; in the operation, because the weight of the air conditioner external unit is heavy, the fixing plates on the left side and the right side of the lower end of the air conditioner external unit are taken down from the foundation screws or the foundation screws are sleeved in the fixing plate holes on the left side and the right side of the lower end of the air conditioner external unit, and the air conditioner external unit needs to be lifted manually, so that the operation is very troublesome, the working strength of an installer can be increased, and sometimes, the horizontal position of the air conditioner external unit can be adjusted by repeating the procedures for. In addition, when the fixing plate holes in the left side and the right side of the lower end of the air conditioner external unit are sleeved in the foundation screws, due to the fact that the air conditioner is lifted manually, in the alignment process, due to the fact that the foundation screws are located at the lower end, the sight of operators is poor, the alignment process is long, and the labor intensity of workers can be increased. Furthermore, when the maintenance outer unit needs to be transported to a maintenance department for maintenance, after the nuts of the ground screws are disassembled, the air conditioner also needs to be lifted manually, the fixing plates and the ground screws on the left side and the right side of the lower end of the outer unit of the air conditioner are separated (some ground screws and the opening side ends of the fixing plates are tightly leaned against each other, and the fixing plates and the ground screws of the outer unit of the air conditioner can be separated only by a large upward external force), so that the whole outer unit of the air conditioner can be carried, therefore, the maintenance and disassembly mode also has the defects of troublesome operation and increased working strength. Based on the above, it is necessary to provide a device for facilitating installation of a central air conditioner.

SUMMERY OF THE UTILITY MODEL

In order to overcome various defects in the installation and disassembly of the existing central air conditioner, the utility model provides a lifting plate which is small in size and compact in structure and is driven by a motor reducing mechanism, in use, the lifting plate is positioned at the lower end of a shell of an air conditioner outdoor unit (the height of the lower end of the shell of the air conditioner outdoor unit is separated from the ground, and fixing plates at the left side and the right side of the lower end of the outdoor unit are contacted with the ground), when a power output shaft of the motor reducing mechanism rotates clockwise, the lifting plate can synchronously drive the air conditioner outdoor unit to move upwards and pull the ground away for a distance, so that the fixing plates at the left side and the right side of the lower end of the outdoor unit are separated from a foundation screw rod, an installer can conveniently increase and decrease the foundation screw rod gasket for operation, as the lifting plate is provided with rollable steel balls, the air conditioner outdoor unit, the lifting position for installing and using the central air conditioner is convenient, and the labor intensity is reduced for installation personnel.

The utility model provides a technical scheme that its technical problem adopted is:

a lifting position for installing a central air conditioner comprises a motor speed reducing mechanism and a power switch, and is characterized by further comprising a lower bottom plate, an internal thread pipe, a fixed shell, a guide rod, a guide pipe, a lifting plate and a limiting plate, wherein the limiting plate is installed on one side of the lower bottom plate, the fixed shell is of a cylindrical structure, the outer side of the lower end of the fixed shell is installed at the upper end of the left side of the lower bottom plate, a supporting ring plate is arranged at the upper end of the fixed shell, a bearing seat is arranged in the middle of the upper end of the supporting ring plate of the fixed shell, a bearing is arranged in the bearing seat, the lower portion of a shell of the motor speed reducing mechanism is installed at the bottom in the fixed shell, a power output shaft of the motor speed reducing mechanism is located in an inner ring of the bearing, the power output shaft is located at the upper end of the bearing and is provided with external threads from top to bottom, the lower, the lower end of the guide rod is sleeved in the guide pipe, the upper end of the guide rod is installed at the lower end of the left middle part of the lifting plate, a circular groove is formed in the upper middle part of the right lower end of the lifting plate, the lifting plate at the upper end of the circular groove is provided with an annular groove, steel balls are installed in the circular groove, one pole of a 220V alternating-current power supply is connected with a power switch inlet wire end through a wire, the other pole of the 220V alternating-current power supply is connected with one of the inlet wire ends of the motor speed reducing mechanism through a wire, two connecting terminals of a nonpolar electrolytic capacitor of a motor matched with the motor of the motor speed reducing mechanism are respectively connected with two outlet wire ends of.
