Abstract

The invention discloses a device for fixing a folded wheeled excavator working device. The device comprises a fixing bracket (11) and a clamping plate (16), and the fixing bracket (11) is fixedly connected to the upper end of a vehicle frame (13) and located below a hopper rod (12) and on the front parts of a platform (14) and a slewing bearing (15); and the clamping plate (16) is fixedly connected to the side face of the hopper rod (12), and when the hopper rod (12) is folded and makes contact with the fixing bracket (11), the clamping plate (16) just makes contact with the fixing bracket (11). When the working device of a combined movable arm is folded, the device can limit the displacement of the working device in the left, right, down and front directions to ensure the travelling safety of a vehicle at a highway.

Description

technical field [0001] The invention belongs to the technical field of excavators, in particular to a fixed support device for a folded arm of a wheeled excavator. Background technique [0002] After the working device of the combined boom of the wheel excavator is folded, when driving at high speed, the braking of the vehicle will cause the working device to move back and forth under the action of its own inertial force. If it is not fixed, the forward and backward movement of the working device will cause unpredictable consequences, such as damage to the opening and closing cylinder or boom, or rapid extension to cause damage to the vehicle in front. Contents of the invention [0003] The present invention aims to provide a fixing device for a folded working device of a wheeled excavator. When the working device of a combined boom is folded, the displacement of the working device to the left, right, down and forward can be limited to ensure that the vehicle is Safety wh...
