Rotary drilling rig provided with remote control plate-loading vehicle

Abstract

The invention discloses a rotary drilling rig provided with a remote control plate-loading vehicle and belongs to the technical field of engineering mechanical equipment. According to the rotary drilling rig, an upper vehicle is fixedly mounted at the upper end of a lower vehicle, a mast is fixedly mounted at the left side of the upper vehicle, the upper end of the mast is fixedly connected with apulley yoke, the lower end of the pulley yoke is fixedly connected with a buffer seat, an upper stop block and a lower stop block which are in symmetry are fixedly connected into the buffer seat, theupper stop block, the lower stop block and the buffer seat define a telescopic chute, and a spring is connected into the telescopic chute in a contact mode. According to the rotary drilling rig, thebuffer seat and a shock absorption sleeve which are arranged have the functions of buffering and shock absorption, shaking of a steel wire rope due to excessively high winding and unwinding speed canbe avoided, unnecessary friction generated by the steel wire rope as a result of the shaking is avoided, and the service life of the steel wire rope is prolonged; and moreover, an anti-disengaging seat which is arranged has the functions of limiting, disengagement prevention, buffering and shock absorption, the situation that a drilling error is generated due to radial movement, caused by the factthat a drilling tool encounters a hard material, of a drill pipe can be avoided, and the drilling precision of the rotary drilling rig is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, and more specifically, to a rotary drilling rig with a remote-control upper pallet truck. Background technique [0002] In recent years, with the continuous maturity of rotary drilling rig technology, the domestic market has higher and higher requirements for the adaptability of rotary drilling rigs to various working conditions, and there are more and more types and models. [0003] At present, when an existing rotary drilling rig with a remote control loading and unloading vehicle is in use, it may vibrate due to the excessive speed of retracting and unwinding the wire rope. The vibration force causes the wire rope to rub against other parts of the rotary drilling rig during retraction , which greatly shortens the service life of the steel wire rope, and when the existing rotary drilling rig of the remote control pallet truck encounters a hard rock or object during dril...

Problems solved by technology

[0003] At present, when an existing rotary drilling rig with a remote control loading and unloading vehicle is in use, it may vibrate due to the excessive speed of retracting and unwinding the wire rope. The vibration force causes the wire rope to rub against other parts of the rotary drilling rig during retraction , which greatly shortens the service life of the steel wire rope, and when the existing rotary drilling rig of the remote control pallet truck encounters a hard rock or object during drilling, it may cause the drill rod to move radially, thus causing the drilling position to change. Offset, which leads to deviations in drilling accuracy
