Description
Technical Field
The utility model relates to vehicle equipment for tunnel construction, in particular to a cab lifting guide device with a buffering function.
Background
With the rapid development of city construction in China, tunnel construction is more and more common, and tunnel transportation equipment matched with the tunnel construction equipment is also developed rapidly. The tunnel transport vehicle as a supporting device for tunnel construction is not as mature and standardized as a conventional engineering vehicle, and some functions and details need to be further improved and improved. For example, in order to avoid the impact and vibration of vehicle components caused by uneven road surfaces while ensuring the normal function of the equipment, a buffer device is added between the vehicle cab and each connector. However, in order to ensure reliable connection of components such as the cab, the components also have lifting and guiding functions, and in addition, the comfort of drivers and passengers and the service life of equipment are considered, a mechanism with buffering and lifting and guiding functions needs to be specially developed for realizing the functions.
The traditional cab lifting guide mechanism is generally free of buffering, the cab is directly connected with the guide post and the lifting oil cylinder, and the mode enables the vehicle to bump very when passing through a rugged road, so that the driving experience is poor, and the service life of components is influenced. The cab is hung and installed in some schemes, a buffer base or buffer rubber is added at the connection part of the cab, and the lifting oil cylinder and the guide mechanism are connected with the cab and the frame through a mounting frame; although the scheme can play a certain role in shock absorption and the stress of the cab is relatively uniform, the scheme cannot be installed due to the limited headspace in many occasions. Part of the scheme is similar to the design of a front fork shock absorber of a motorcycle and has a certain shock absorption effect, but the lifting height of a cab cannot meet the requirement, and the installation space is also a problem; in addition, the guide mechanism cannot bear large horizontal pulling force, and the dragging function of the vehicle under the emergency rescue condition cannot be realized, so that the design requirement cannot be met.
In summary, most of the conventional cab structures are only provided with lifting and guiding functions, although some of the cab structures are additionally provided with buffering devices, the buffering devices and the lifting and guiding mechanisms are independently separated, and other cab structures are complex and limited in lifting function due to space limitation although the buffering effect is good, and the guiding function is not well stressed. Therefore, there is a need for improvements in the prior art.
