Abstract

Coupling sleeve for connecting a threaded rock bolt (1) to an impact rock drilling machine (2) comprising a first part (3) provided with an internal thread (4) for connection of the rock bolt (1) and a second part (5) provided with an internal thread (6) for connection of the rock drilling machine (2), whereby the second part (5) comprises a transversely to a longitudinal axis (9) on the coupling sleeve arranged locking device (7) which cooperates with a region (8) on the rock drilling machine (2) for preventing that the coupling sleeve and the rock drilling machine (2) are separated.

Description

Be used for threaded anchor rod be connected to impact on the rock drill in conjunction with sleeve
Technical field
The present invention relates to a kind of be used for threaded anchor rod be connected to impact on the rock drill in conjunction with sleeve, the invention particularly relates to a kind of particular design in conjunction with sleeve, when rock drill separated with anchor pole, it guaranteed that some in being threaded of in conjunction with sleeve two at first unclamps.
Background technology
Guarantee some schemes that is threaded and at first unclamps in known being used at present, in SE433097, see, use screw thread so that obtain than being threaded that other screw thread is difficult to unclamp more with different pitch, different screw thread or cone.These schemes have the shortcoming that must use non-standard parts.It is so that obtain correct connection that people also always must check for which end.
In the trial that addresses the above problem, see that in WO/02057591 collet head is held on the screw thread that is difficult to unclamp.Verified this scheme has the shortcoming of the shock wave load that can not bear is threaded is applied in boring procedure.
Summary of the invention
The objective of the invention is to defined in the present invention subsequently overcomes above-mentioned shortcoming by following means: provide have locking device in conjunction with sleeve, a zone in the handle crossover sub of this locking device and rock drill cooperates, and is separated in conjunction with sleeve and rock drill when rock drill separates with anchor pole so that prevent.
Description of drawings
A kind of embodiment of the present invention describes with reference to the accompanying drawings as follows, wherein
Fig. 1 illustrates according to of the present invention in conjunction with sleeve and handle crossover sub and be used for and the phantom drawing that combines the anchor pole that sleeve cooperates.
Fig. 2 illustrates by the cross section according to the device of Fig. 1, and wherein anchor pole and rock drill are connected in conjunction with on the sleeve.
The specific embodiment
What illustrate in the drawings comprises the first 3 that provides internal thread 4 in conjunction with sleeve, and threaded anchor rod 1 can be connected on the above-mentioned internal thread 4.Threaded anchor rod provides unshowned drill bit, and this drill bit is used to bore the hole that anchor pole carries out grappling.Also comprise the second portion 5 that provides internal thread 6 in conjunction with sleeve, rock drill 2 can be connected on the above-mentioned internal thread 6.In the accompanying drawings, show the handle crossover sub that belongs to rock drill.This has the longitudinal axis 9 in conjunction with sleeve.Providing the boring 10 that two crosscut axles 9 are arranged in conjunction with sleeve at its second portion 5, is that the locking device 7 of two spring catch forms is arranged in the boring 10.Locking device 7 matches with zone 8, separates with rock drill 2 in conjunction with sleeve so that prevent.
When anchor pole 1 was set, the handle crossover sub that belongs to rock drill 2 was rotated when it is impacted.Pass through anchor pole 1 drilling bore hole by this, and anchor pole will carry out grappling in this hole.In boring procedure, locking device 7 unloadings.After boring, anchor pole 1 will be from conjunction with separating the sleeve and staying in the rock.Here rock drill is rotated to be used to unclamp and is threaded.By locking device 7 with have cooperation between the zone 8 of minor diameter more than the screw thread of handle crossover sub, prevent rock drill 2 and separate in conjunction with sleeve.Afterwards, boring is filled with cement or resin around anchor pole, is used for anchor pole is anchored in the boring.

Claims (1)

1. be used for threaded anchor rod (1) be connected to impact on the rock drill (2) in conjunction with sleeve, comprise first (3) that provides the internal thread (4) that is used to connect anchor pole (1) and the second portion (5) that provides the internal thread (6) that is used to be connected rock drill (2), it is characterized in that, second portion (5) comprises the locking device (7) that the crosscut longitudinal axis (9) is arranged in conjunction with sleeve, this locking device (7) matches with the zone (8) on the rock drill (2), is used to prevent be separated in conjunction with sleeve and rock drill (2).
