The cab lift device
Technical field
The utility model belongs to automobile component, is specifically related to a kind of automobile cab jacking system.
Background technology
For the ease of operation, the operator's compartment of some automobile need be designed to liftable structure, the operator's compartment of aircraft towing for example, aircraft towing requires short vehicle body, so that to the operation of aircraft, fall operator's compartment during the pushing tow aircraft to improve proximity, rise operator's compartment when retreating, to obtain good rearward vision to aircraft.Known cab lift device, comprise the carriage that is fixedly installed on operator's compartment bottom, be fixedly installed on guide rail, hydraulic actuating cylinder, roller on the vehicle frame, utilize hydraulic actuating cylinder pushing tow carriage to drive to be fixed on roller on the carriage to roll and realize the lifting of operator's compartment along guide rail, the operation noise is big, easy to wear, and the structural machinability of roller and guide rail is complicated, the tooling cost height.
The utility model content
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is to provide a kind of novel cab lift device, and simple in structure, good manufacturability, cost are lower.
The cab lift device that the utility model provides, be arranged on the operator's compartment bottom, comprise carriage, hydraulic actuating cylinder, guide rail, slide block, carriage is fixedly installed on the operator's compartment bottom, and an end of hydraulic actuating cylinder is arranged on the carriage, and the other end is arranged on the vehicle frame, guide rail is fixedly installed on the vehicle frame, described slide block is fixed on the carriage, and is sleeved on the guide rail, and slide block can slide along guide rail.
The cab lift device that the utility model provides, its beneficial effect shows: simple in structure, good manufacturability, low, the operation noiselessness, not easy to wear of cost.
