Problems solved by technology
During the construction process of the rotary drilling rig, the drill pipe may fall into the deep hole due to the breakage or damage of the wire rope, or the inside of the hole may collapse and the drill pipe and the drill bucket may be buried in the hole. If it is not handled in time, the resulting economic loss Huge and even affect the foundation construction of the entire project

The invention discloses a drill pipe rescuing device used for a rotary drilling machine and belongs to the mechanical field. The drill pipe rescuing device comprises a winding plant, a steel wire rope, a steel wire rope clamp and a connecting rod mechanism. The winding plant is connected with one end of the steel wire rope. The other end of the steel wire rope is hinged to the connecting rod mechanism through the steel wire rope clamp. The connecting rod mechanism comprises a force bearing plate, 2n connecting rods and clamping plates. One end of each connecting rod is hinged to the force bearing plate. The clamping plates include the left clamping plate and the right clamping plate which are symmetrically arranged relative to the force bearing plate. The other end of each connecting rod is hinged to the left clamping plate and the right clamping plate respectively. Arc-shaped lifting rings are arranged on the top of the left clamping plate and the top of the right clamping plate. An auxiliary steel wire rope used for the connecting rod mechanism to be unfolded is connected to the left clamping plate and the right clamping plate. The drill pipe rescuing device is simple in structure, reasonable in design, convenient to use and capable of fast taking out a drill pipe or a drilling bucket embedded underground, and the situation that the drill pipe falls into a deep hole or collapse happens in the hole and consequently larger economic losses are caused is avoided.
Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to a drill pipe rescue device for a rotary drilling rig. Background technique [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers, and is widely used in various foundation constructions such as cast-in-place piles, diaphragm walls, and foundation reinforcement. [0003] At present, rotary drilling rigs mainly rely on drill pipes and buckets to complete pile foundation construction. The main function of the drill pipe is to transmit the torque output by the rotary drilling rig and increase the hole depth at the same time. At present, the drill pipes used in pile foundation construction are divided into machine lock drill pipes, friction group drill pipes and combined drill pipes. The working princi...
