Description

Technical Field

[0001] The utility model relates to the technical field of geophysical exploration, in particular to a special crawler chassis for controllable vibrator. Background Art

[0002] Using controllable vibrators to artificially excite seismic waves is an important method for seismic exploration. Controllable vibrators have super strong anti-interference capabilities. Since the signal spectrum and basic characteristics generated by controllable vibrators can be artificially controlled, certain interference frequencies can be avoided when designing the source scanning signal, and the absorption of seismic signals by the strata can be compensated. This is difficult to do with other artificial ground sources and explosive sources. Therefore, using controllable vibrators for seismic exploration can obtain data with sufficient reflected energy, signal-to-noise ratio and signal resolution that can meet the needs of geological exploration.

[0003] For confined areas with narrow spaces and unclear safety conditions, existing controllable vibrators cannot enter the above areas for construction due to their large size and inflexible movement. At the same time, manned controllable vibrators are easy to cause personal injury accidents when constructing in areas with poor safety conditions due to their large body and poor visibility. Remote-controlled crawler-type self-propelled controllable vibrators are small in size, flexible in steering, and have strong climbing ability. They are suitable for construction in confined spaces and are remotely controlled wirelessly, making them safer and more reliable to use.

[0004] Conventional crawler chassis have the disadvantages of poor reliability, poor structural adaptability, and unreasonable track tensioning structure. Because the construction area of ​​remote-controlled crawler vibrators has complex and changeable working conditions and high construction intensity, the chassis frame needs to be strong, reliable, and durable. In addition, conventional crawler chassis are usually used for transportation or general equipment, with simple crossbeam structures and low ground clearance. Because the vibrator of a controllable vibrator needs to contact the ground to work, it is often necessary to check and adjust the airbag pressure, inflate and deflate it, and replace accelerometers, displacement sensors and other components. Conventional crawler chassis have a small operating space and are inconvenient to adjust and maintain. The conventional crawler chassis tensioning mechanism is weak and relies on rigid tensioning with a screw. There is a lack of buffering capacity, which can easily lead to deformation and failure of the tensioning mechanism. Utility Model Content
