Description
Technical field
The utility model relates to a kind of snubber, is applicable to and the high pneumatic dth drill bore operation.
Background technology
Along with the develop rapidly of the development of the national economy, in the process that is used for the infrastructure pulling national economic development, how quick, efficient, stable in bore operation, economy becomes present urgency problem to be solved.
Rig and down-the-hole air hammer employing at present be drilling rod and drilling rod ways of connecting successively, in drilling process, the reaction force that rock impact device is huge, also can be delivered on drilling rod and the rig joint with the form of energy waves, make the screw thread distortion, inconvenience greatly when impacting the dismounting of device and drilling rod, thereby drilling life of drill pipe shortens the drilling efficiency reduction.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, long service life, connects reliably, mainly reduces drilling rod, rig and is subjected to a kind of buffer of recoiling and hitting and damage.
The purpose of this utility model is achieved by following technical proposals:
A kind of snubber, comprise outer six side's top connections, slide bar, jack rod sleeve, resilient key, the dish ring, O type circle, interior six side's lower contacts, be provided with slide bar between described outer six side's top connections and the described interior six side's lower contacts, described outer six side's top connections, be provided with centre bore in six side's lower contacts and the described slide bar in described and be interconnected, between described slide bar and the described outer six side's top connections dish ring is installed, described slide bar is fixed in described outer six side's top connections by the described jack rod sleeve that is installed in described outer six side's top connection tail ends, six side's lower contacts are installed in the tail end of described slide bar in described, are provided with resilient key between the inwall of described slide bar and described outer six side's top connections in described outer six side's top connections.
In the utility model, described dish ring set is contained on the described slide bar, and described dish ring is one group 7 a dish ring.
In the utility model, adopt between described jack rod sleeve and the described outer six side's top connections to be threaded.
In the utility model, described slide bar adopts spline to be connected with described outer six side's top connections.Described resilient key is installed in the described spline.
In the utility model, described outer six side's top connections adopt six sides to be connected with described interior six side's lower contacts with drilling rod.The front end of described slide bar is provided with O type circle.
Owing to adopt above-mentioned scheme, described dish spring is sleeved on the described slide bar, described outer six side's top connections are connected by described dish spring with described slide bar, and described dish spring plays cushioning effect to anti-force, can effectively reduce in the ballistic motion rock stratum reaction force to the damage of drilling rod and screw thread thereof.
In sum, described utility model---a kind of snubber has simple in structure, easy to use, long service life, safe and reliable, can effectively reduce the damage that drilling rod and rig are impacted when creeping into, and is applicable to that the drilling rod of high blast down-the-hole drilling tool connects.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of buffer device in detail.
As Fig. 1,2, shown in 3, a kind of snubber, comprise outer six side's top connections 1, slide bar 2, jack rod sleeve 3, resilient key 4, dish ring 5, O type circle 6, interior six side's lower contacts 7, be provided with slide bar 2 between described outer six side's top connections 1 and the described interior six side's lower contacts 7, described outer six side's top connections 1, be provided with centre bore in six side's lower contacts 7 and the described slide bar 2 in described and be interconnected, between described slide bar 2 and the described outer six side's top connections 1 dish ring 5 is installed, described slide bar 2 is fixed in described outer six side's top connections 1 by the described jack rod sleeve 3 that is installed in described outer six side's top connections, 1 tail end, six side's lower contacts 7 are installed in the tail end of described slide bar 2 in described, are provided with resilient key 4 between the inwall of described slide bar 2 and described outer six side's top connections 1 in described outer six side's top connections 1.
In the utility model, described dish ring 5 is sleeved on the described slide bar 2, and described dish ring 5 is one group 7 a dish ring 5.
In the utility model, adopt between described jack rod sleeve 3 and the described outer six side's top connections 1 to be threaded.
In the utility model, described slide bar 2 adopts spline to be connected with described outer six side's top connections 1.Described resilient key 4 is installed in the described spline.
In the utility model, described outer six side's top connections 1 adopt six sides to be connected with described interior six side's lower contacts 7 with drilling rod.The front end of described slide bar 2 is provided with O type circle 6.
The utility model operating principle is as follows: as shown in Figure 2, when the down-the-hole air hammer operate as normal is impacted rock, reaction force passes to slide bar 2 along drilling rod, interior six side's lower contacts 7 successively, and dish spring 5 is elastic shrinkage under slide bar 2 effects, and reaction force is converted into the elastic potential energy of dish spring.
As shown in Figure 1, when down-the-hole air hammer impactor rock or quit work not, the dish spring extends under the effect of self elastic force.
