Automatic installing and detaching device of drill rod of horizontal directional drilling machine

Abstract

The invention discloses an automatic installing and detaching device of a drill rod of a horizontal directional drilling machine. A guiding sleeve is welded to a stand column (13), and a horizontal guiding rod (11) is installed in the guiding sleeve of the stand column (13). One end of the horizontal guiding rod (11) is fixed on a horizontal installation seat (9), and a horizontal limiting installation board (14) is fixed on the stand column (13). One end of a horizontal sliding oil cylinder (12) is fixed on the horizontal installation seat (9), and the other end of the horizontal sliding oil cylinder (12) is fixed on the guiding sleeve of the stand column (13). A vertical guiding rod (10) is installed on the horizontal installation seat (9), one end of a vertical sliding oil cylinder (15) is fixed on the horizontal installation seat (9), and the other end of the vertical sliding oil cylinder (15) is fixed on a vertical installation seat (7). A second sensing switch (32) is arranged on the vertical installation seat (7), and a grasping hand oil cylinder (8) is respectively connected with the vertical installation seat (7) and a grasping hand (4). The automatic installing and detaching device can avoid idle work when the drill rod is automatically installed and detached, ensure the personal safety of operators and meanwhile reduce energy consumption.

Description

technical field [0001] The invention relates to a horizontal directional drilling machine, in particular to an automatic loading and unloading device for drilling rods of the horizontal directional drilling machine. Background technique [0002] Horizontal directional drilling rig is a construction machine for laying various underground utilities (such as pipelines, cables, etc.) without excavating the ground surface. It is widely used in water supply, electricity, telecommunications, natural gas, gas, oil and other pipelines In paving construction, it is suitable for sandy soil, clay, pebbles and other ground conditions, and it can be constructed in most non-hard rock areas in my country. [0003] During the construction process of the horizontal directional drilling rig, according to different conditions, it is necessary to frequently install or disassemble the drill pipe. This action is generally done manually. Repeated installation and unloading of the drill pipe may caus...

Problems solved by technology

[0003] During the construction process of the horizontal directional drilling rig, according to different conditions, it is necessary to frequently install or disassemble the drill pipe. This action is generally done manually. Repeated installation and unloading of the drill pipe may cause equipment damage due to misoperation by the operator. Or the personal injury or death of construction personnel, which will cause serious economic losses and personal safety issues

[0004] At present, although the equipment at home and abroad also uses the drill pipe loading and unloading device, the technology of adding or placing the drill pipe on the lower side of the drill pipe box is adopted, that is, the working device is required to jack up the whole box of drill pipe during work, and the horizontal movement of the drill pipe depends on reciprocating Driven by the moving shuttle arm; this technology has disadvantages such as large frictional resistance and high energy loss, and the structural parts are complex, and the mechanical wear between the structural parts is also large, which does not meet people's requirements for energy saving, consumption reduction, and environmental protection
