Embodiment Construction

[0015] The specific implementation will be described below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 to Figure 3 As shown, the cab installation platform includes a hinged front hood 14 and a rear hood 11, wherein the hinge axis of the front hood 14 is in a horizontal direction, so that the front hood 14 can turn upwards in the vertical direction around the horizontal hinge axis. The hinge axis of the rear hood is in a vertical direction, so that the rear hood 11 can be horizontally rotated around the vertical hinge axis to open. The rear lower part of the driver's cab 1 is recessed forward, and the depression reaches the middle part of the driver's cab from bottom to top, so that the rear part of the driver's cab presents an inverted stepped shape. There is a bracket 6 protruding upwards to the top of the installation platform on the cab installation platform. The ladder step of the cab 1 forms a hinge through the hinge pin 8 and the connecting...

Abstract

The invention relates to a small excavator which aims to overcome the defects that for an existing small excavator with a cab mounted in a hinged mode, turning up of the cab is limited, and consequently the existing small excavator with the cab mounted in the hinged mode is inconvenient to repair. The small excavator is structured and comprises a cab and a mounting platform for mounting the cab, wherein the cab is connected and mounted the mounting platform in the hinged mode, a turning hinged point of the cab is arranged at the rear of the front-and-rear direction of the cab and hinged to the mounting platform at the top of the mounting platform, a lifting device is arranged on the lower portion of the cab and lifts the cab to make the cab rotate around the hinged point. According to the small excavator, the hinged point is located at the rear of the cab and hinged to the top of the mounting platform, the distance from the hinged point to the bottom of the cab is large, when the cab turns by a small angle around the hinged point, the bottom of the cab can be wholly lifted by a large height, and large space is provided for repairing of other parts which are mounted on the mounting platform and located below the cab.

Description

technical field [0001] The invention relates to a construction machine, in particular to a small excavator. Background technique [0002] Construction machinery, especially small hydraulic excavators, often need to arrange many parts at the bottom of the cab due to the size and overall layout of the machine, such as hydraulic control valves, slewing motors and slewing center joints. In addition, due to the layout of the engine, one side of the engine compartment will always be close to the rear of the cab. Therefore, for small excavators, it is very inconvenient when these parts fail. [0003] At present, when construction machinery is overhauling the parts under the cab, the cab is usually designed to be reversible, that is, the bottom of the cab is hinged to the mounting bracket through a hinge. When it is necessary to detect parts, use the auxiliary device to turn the cab forward for maintenance. When the cab is turned forward, it will be affected by the working device...
