Abstract

The invention provides a belt tensioning device for fixing and driving an air condition compressor for an excavator. The belt tensioning device is characterized by comprising a base and a compressor installation seat, wherein the base is provided with a fixing guide rail and a locking guide rail; the fixing guide rail is fixedly arranged on the base; the locking guide rail is arranged opposite to the fixing guide rail; the left side and the right side of the compressor installation seat are respectively arranged on the fixing guide rail and the locking guide rail; the compressor installation seat can slide along the fixing guide rail and the locking guide rail in the longitudinal direction; a compressor is locked on the compressor installation seat and is provided with a compressor belt wheel; the base is fixedly connected with an adjusting bolt; the compressor installation seat is fixedly connected with an adjusting screw block; the adjusting screw block is in threaded connection with the adjusting bolt; the compressor installation seat can be driven to slide along the fixing guide rail and the locking guide rail in the longitudinal direction by rotating the adjusting bolt, and thus the distance between the compressor belt wheel and an engine driving wheel can be adjusted. According to the belt tensioning device provided by the invention, the torsion of a belt can be reduced, and the reliability is increased.

Description

technical field

[0001] The invention relates to an air conditioner compressor fixing and driving belt tightening device for an excavator. Background technique

[0002] In the field of excavator manufacturing, air conditioning is an indispensable device, which can regulate the temperature in the cab and improve the comfort of the operating environment. In general, an air conditioner is composed of a compressor, an air conditioning unit, a condenser, a liquid storage tank, a refrigerant pipe, a drive belt, a belt tensioner, etc. The compressor is connected to the engine through a compressor fixing bracket, and the compressor pulley The driving belt is connected with the engine driving wheel and the belt tensioner, and the power of the engine driving wheel is transmitted to the compressor pulley through the belt, so as to drive the compressor to work. The belt is flexible, and a certain deflection must be ensured to ensure power transmission. Usually, a tensioner is used to ad...

Examples

Embodiment 1

[0030] Such as figure 1 As shown, it is a structural schematic diagram of an air-conditioning compressor fixing and driving belt tensioning device for an excavator. The air-conditioning compressor fixing and driving belt tensioning device for an excavator includes a base 2 and a compressor mounting seat 1, such as figure 2 As shown, the base 2 is locked on the engine through the base fixing bolts 3 to support the entire device. Such as image 3 As shown, the base 2 is provided with Figure 6a and 6b The fixed guide rail 6 and the locking guide rail 12 are shown, the fixed guide rail 6 is fixed on the base 2, the locking guide rail 12 is arranged opposite to the fixed guide rail 6, and the left and right sides of the compressor mounting seat 1 are respectively arranged on On the fixed guide rail 6 and the locking guide rail 12 and can slide longitudinally along the fixed guide rail 6 and the locking guide rail 12, the compressor mounting seat 1 is clamped by the fixing guid...
