The invention discloses a lifting and pressing device of a truck-mounted drilling rig. The device comprises a hydraulic oil cylinder (8), a movable pulley assembly (5), an upper pressing fixed pulley (1), a lower pressing fixed pulley (13), lifting steel wire ropes (7) and a pressing steel wire rope (3), wherein the hydraulic oil cylinder is vertically mounted in a front opening derrick of the truck-mounted drilling rig; the two ends of the hydraulic oil cylinder are connected with a derrick base and the movable pulley assembly; the movable pulley assembly comprises a pulley bracket, a lifting movable pulley (4) and a pressing movable pulley (6); the lower pressing fixed pulley comprises two pairs of fixed pulleys; the upper pressing fixed pulley comprises two pairs of fixed pulleys; two lifting steel wire ropes are provided and bypassed through the lifting movable pulley; and two ends thereof are respectively fixed on a power head slide frame and the derrick base. The device realizes functions of lifting and pressing in the operation of the truck-mounted drilling rig, provides a larger working travel to a top drive type power head, and is stable in drilling process, excellent in well mouth centering performance, compact in structure, simple in installation, high in bearing capacity, low in cost and high in drilling efficiency.
Description
technical field [0001] The invention relates to a lifting and pressing device, in particular to a lifting and pressing device for a vehicle-mounted drilling rig, belonging to the technical field of vehicle-mounted drilling rigs. Background technique [0002] The vehicle-mounted drilling rig is a multi-process drilling construction equipment with a high degree of automation. The drilling device is installed on the chassis of the car, which has good mobility and operability. Therefore, it has been widely used in drilling wells, geological exploration, mine rescue, coal seam In engineering fields such as gas extraction, the drilling depth varies from hundreds of meters to several thousand meters according to different needs. [0003] At present, most of the vehicle-mounted drilling rigs work in the way of hoisting, crown block, traveling block, hook lifting, and turntable drive. The hoisting drives the hook to lift the swivel to move up and down, and the swivel is connected to ...
