Transmission system of a vehicle-mounted drilling and repairing machine

Abstract

The invention discloses an on-board drilling and workover rig transmission system. The system comprises a power system which is formed in the mode that an engine and a hydraulic transmission gear boxare connected through a flywheel casing, and the power output of the power system is divided into three parts including the first part used for driving a winch drum, the second part used for driving arotation plate, and the third part used for driving wheels. The winch drum is braked through a main brake connected to the winch drum and an assistant brake connected to an input port of a gear transmission box. According to the on-board drilling and workover rig transmission system, the size in the width direction of a winch is reduced, and a clutch and an assistant brake which were installed onthe two sides of the winch drum previously are removed so that the whole width of the winch can be controlled to be within a reasonable range; a winch clutch is integrated above an angle transmissionbox, when winch hanging connection and separation are conducted before the transmission gear box, the operation torque of the clutch can be further reduced, and a smaller type of clutch can be adopted to make the structure more compact.

Description

technical field [0001] The invention belongs to the field of oil drilling rig equipment manufacturing, and relates to a transmission system of a vehicle-mounted drilling and repairing machine. Background technique [0002] At present, the transmission mode generally adopted by vehicle-mounted drilling and repairing machines for oil drilling is to match one or two diesel engines with a hydraulic transmission box, and transfer the output through the transfer box. The upper power output port of the transfer case passes through the transmission shaft to the corner transmission case, passes through the corner case, and then passes through the chain box to the drawworks to drive the main drum to realize the lifting operation during drilling; the middle power output port of the transfer case is driven by the transmission shaft and directly passes through the turntable The transmission box and the vertical chain box drive the turntable behind to realize the drilling rotation operati...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a vehicle-mounted drilling and repairing machine transmission system, which solves the problem that the overall width of the drawworks in the prior art is large, so that the width of the entire vehicle cannot meet the requirement of a width limit of 2550 mm in GB1589-2016, which affects the announcement and driving of the main vehicle.
