Abstract
The utility model is a kind of jumbo beche.Be made up of a cylinder, be processed into internal thread in one end of cylinder inside, other end processing inner conical.Female end and inner conical end junction are a through hole.The diameter of female end is kept straight on according to the little head end of drilling rod on forward beam and is determined.The diameter of inner conical end is determined according to the disconnected plane of disruption diameter dropping on drilling rod in hole.The little head end of drilling rod on jumbo beche female end one end and jumbo forward beam combines, and is advanced, impacts by hammer drill, makes disconnectedly to drop on drilling rod wedging in hole and, on inner conical, form wedging, and hammer drill retreats the disconnected drilling rod dropped in hole of pull-out.Jumbo beche of the present utility model efficiently solve jumbo boring procedure interrupt drop on drilling rod in hole be difficult to take out problem, it is simple to operation, and cost of manufacture is low.
Description
Technical field
The utility model relates to rock drilling technical field, specifically for solve jumbo boring procedure interrupt drop on drilling rod in hole be difficult to take out jumbo beche.
Background technology
Jumbo is a kind of rock drilling equipment that tunnels and underground engineering adopts, and it can move and support that multiple stage hammer drill carries out drilling simultaneously.Hammer drill boring consumptive material is bit shank, adapter sleeve, drilling rod and drill bit, is referred to as drilling tool, expensive.Jumbo, when carrying out deep hole operation, often 6.1 meters of mobile jibs is connected to the 1 little bar of root at the most.Along with the increase of drilling depth, the drilling rod be connected to is more, once certain root drill rod breaking, drilling rod, the drill bit of that root drilling rod front end all will be retained in hole and cannot take out, and cause the wasting of resources.For avoiding a kind of beche of the generation of this situation spy invention.Easy, the practical and convenient and low price of this tool making.
Summary of the invention
The purpose of this utility model is to provide a kind of jumbo beche interrupting dropping on drilling rod in hole for taking out jumbo boring procedure.
The technical solution of the utility model is: a kind of jumbo beche is made up of a cylinder, is processed into internal thread in one end of cylinder inside, other end processing inner conical.
Female end and inner conical end junction are a through hole.
The diameter of female end is kept straight on according to the little head end of drilling rod on forward beam and is determined.
The diameter of inner conical end is determined according to the disconnected plane of disruption diameter dropping on drilling rod in hole.
The little head end of drilling rod on jumbo beche female end one end and jumbo forward beam combines, and is advanced, impacts by hammer drill, makes disconnectedly to drop on drilling rod wedging in hole and, on inner conical, form wedging, and hammer drill retreats the disconnected drilling rod dropped in hole of pull-out.
Jumbo beche of the present utility model efficiently solve jumbo boring procedure interrupt drop on drilling rod in hole be difficult to take out problem, it is simple to operation, and cost of manufacture is low.
Accompanying drawing explanation
fig. 1 is jumbo beche structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, this jumbo beche is made up of a cylinder, is processed into internal thread 1 in one end of cylinder inside, other end processing inner conical 2.Female end and inner conical end junction are a through hole 3.The diameter of inner conical end is determined according to the disconnected plane of disruption diameter dropping on drilling rod in hole.
The diameter of female end is kept straight on according to the little head end of drilling rod on forward beam and is determined.The diameter of inner conical end is determined according to the disconnected plane of disruption diameter dropping on drilling rod in hole.
During use: first by the drilling rod microcephaly on forward beam engaged through the thread for beche thread segment, putting into breaks falls the hole of drilling rod, and hammer drill forward impelling, withstands on the plane of disruption of drilling rod or adapter sleeve.Blocked the plane of disruption (can be impacted by hammer drill, rotate, repeat this action several times until form wedging) of drilling rod or adapter sleeve by beche other end inner conical surface, hammer drill shrinks back, the disconnected drilling rod dropped in hole of pull-out.
