Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] For the sake of clarity and brevity, the present invention uses the terms "first", "second", "third", and "fourth", which are mainly used to distinguish different components, but do not specifically limit the components.

[0034] figure 1 Shown is a schematic diagram of a winch system of a rotary drilling rig according to an embodiment of the present invention, and the winch system is used for retracting and releasing drill pipes during the drilling operation of the rotary drilling rig. The hoisting system at least includes a rotatable reel 100 and a rope 200 wound on the reel 100. When the reel 100 rotates in one direction, the rope 200 is released; take back. The reel 100 can also be ...

Abstract

The invention discloses a rotary drilling rig as well as a winding drum and a winding system thereof. The winding drum is divided into a first section and a second section, wherein the first section and the second section are provided with rope slots with opposite spiral directions, a middle transition platform is arranged between the first section and the second section, and the middle transition platform is used for guiding a rope to be wound to a first layer of the second section from a second layer of the first section. When the rotary drilling rig is in a full load state, the rope can be positioned in the first layer of the second section, the load is directly borne by the winding drum, the contact stress is low, and the service life of the rope is long. The performance of a dynamical system can be fully used; in addition, the frequency of the rope passing a conventional climbing platform during a working process is lowered.

Description

technical field [0001] The present invention mainly relates to the technical field of piling machinery, in particular to a rotary drilling rig reel, a hoisting system, and a rotary drilling rig equipped with the reel and hoisting system. Background technique [0002] With the rapid development of my country's national economic construction and the accelerated construction of various large-scale projects, the demand for rotary drilling rigs at pile hole construction sites is becoming more and more extensive. Rotary drilling rigs usually use a telescopic drill rod connected to a winch system, which generally includes a rotatable drum and a rope (usually a steel wire rope) wound on the drum. [0003] With the lowering of the wire rope, the weight of the outer drill pipe is gradually borne by the power head. That is to say, when the depth is 0-L (L is the length of a single section of drill pipe), the wire rope and reel bear the weight of the entire drill pipe; The weight of t...
