Description

Technical Field

[0001] The invention relates to the technical field of oil and gas drilling, in particular to a multifunctional vehicle-mounted hydraulic drilling and repair machine derrick device. Background Art

[0002] The vehicle-mounted hydraulic driller and workover rig is one of the important types of oil and gas drilling and workover equipment. This type of driller and workover rig has the characteristics of soft and stable operation, rapid transportation, modularization, lightness and miniaturization. Compared with the electric driller and workover rig, it has no explosion-proof certification requirements. As the country's requirements for wellhead explosion-proof during drilling and workover are becoming increasingly stringent, this type of driller and workover rig has gradually been favored by users in recent years and has great market potential. The derrick device of the vehicle-mounted driller and workover rig is one of the important equipment of the vehicle-mounted driller and workover rig, which is mainly used to realize the lifting and lowering of the top drive equipment during drilling and workover operations. The derrick device is in an upright state when the equipment is working, and is in a horizontal state and transported together with the carrier during transportation.

[0003] The upper and lower bodies of the existing vehicle-mounted hydraulic drilling and repair machine derrick device are guided by a single guide wheel guide rail structure. The main hydraulic cylinder that drives the upper body to lift and lower and the upper body are not equipped with a straightening device. The driving device of the telescopic legs is realized by a built-in hydraulic support leg + an external locking mechanical support leg structure. The water hose is not equipped with a transportation support bracket and needs to be removed during transportation. According to the above analysis, the existing vehicle-mounted hydraulic drilling and repair machine derrick device has the following shortcomings: the derrick device is guided by a single guide wheel guide rail, and the main hydraulic cylinder has no straightening. Under high-speed lifting and lowering conditions, the derrick device is prone to high-frequency instability of the upper body shaking, which will greatly reduce the life of the main hydraulic cylinder; the hydraulic support leg is built inside the hydraulic support leg, which is inconvenient to install and maintain, and it is not easy to find when the hydraulic support leg fails; the external mechanical support has no protective equipment and is easily contaminated and corroded by drilling fluid; the water hose needs to be installed and disassembled frequently, which reduces work efficiency.

[0004] As users pay more and more attention to the reliability of drilling and workover equipment, there is an urgent need to design a vehicle-mounted hydraulic drilling and workover derrick device that is safe, stable, reliable, has a long service life, and is easy to maintain, so as to meet users' requirements for the use of the vehicle-mounted hydraulic drilling and workover derrick device.
