Novel anti-impact vibration reduction device for excavator cab

Abstract

The invention discloses a novel anti-impact vibration reduction device for an excavator cab. The novel anti-impact vibration reduction device comprises a cab body. Multiple support pillars are fixedlyconnected to the top of the cab body, and a top plate is fixedly connected to the top ends of the support pillars. An elastic protection plate is connected to the upper end of the top plate through multiple first extending-and-contracting rods, and a first spring is connected to the outer wall of each first extending-and-contracting rod in a sleeving manner. Movable grooves are symmetrically formed in the two sides of the outer wall of the cab body, and a sliding block is connected into each movable groove in a sliding manner. A support rod is connected to one side of the outer wall of each sliding block in a rotary manner. The end, far away from the corresponding sliding block, of each support rod is connected with the outer wall of a corresponding protection side plate in a rotary manner. A limiting rod is fixedly connected to the bottom of each sliding block, and a third spring is connected outside each limiting rod in a sleeving manner. The novel anti-impact vibration reduction device is simple in structure and easy to operate; impact damage which the cab is subjected to can be effectively reduced; a driver is prevented from being injured; and the device is convenient, fast and ingenious to use and suitable for being widely popularized.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a novel excavator cab anti-shock and vibration damping device. Background technique [0002] Mine excavators are generally equipped with a cab protection device, whose function is to reduce the impact damage to the cab and avoid driver injury when it is impacted or falling objects fall. Existing cab protection device is made of front protection and top protection, and front protection and top protection all adopt pane structure, and material is the combination of steel plate and round steel. There are following deficiencies in the above-mentioned protective device in use: the driver's cab protection is made of round steel, and its bearing capacity is poor, and it is easily deformed when the impact of external force is slightly large. The roof protection adopts a window pane structure. On the one hand, there are problems of poor resistance to smashing and compression. On the o...

Problems solved by technology

The above-mentioned protection device has the following disadvantages in use: the cab protection is made of round steel, and its bearing capacity is poor, and it is easy to deform when it is slightly impacted by an external force

The roof protection adopts the window pane structure. On the one hand, there are problems of poor resistance to smashing and compression. On the other hand, small-sized falling objects will fall on the roof of the cab, causing damage to the roof of the cab and making it difficult to clean
