Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

It referring to Fig.1, is a kind of rotary drilling rig spcific power case disclosed by the utility model, including cabinet 1,1 top of cabinet Be equipped with annular damper cylinder 2.In construction, the drilling rod of rotary drilling rig and the wheel hub of headstock are connected, and drilling rod generates huge It shakes and the top of cabinet 1 is pushed, damper cylinder 2 carries out shockproof cushioning between drilling rod and cabinet 1, it is huge that drilling rod is greatly lowered Big vibration is damaged with impact to caused by cabinet 1.

Referring to Fig.1, damper cylinder 2 include annular bottom plate 3(referring to fig. 2).Annular bottom plate 3 is fixed by being connected and fixed component 15 In 1 top of cabinet.It is connected and fixed the connecting plate 151 that component 15 includes annular, connecting plate 151 is located at annular bottom plate 3 and cabinet 1 pushes up Between end, 151 upper surface of connecting plate is fixedly connected with annular bottom plate 3, and connecting plate 151 and 1 top of cabinet are bolted.Even Fishplate bar 151 increases the contact area of annular bottom plate 3 Yu 1 top of cabinet, promotes the connectivity of annular bottom plate 3 and 1 top of cabinet. It is connected by screw bolts, convenient for the installation and removal of operator while stationarity is high.

Referring to Fig. 2, the inner ring and outer ring of annular bottom plate 3 has been respectively fixedly connected with inner cylinder 4 and outer cylinder 5, inner cylinder 4 and outer cylinder 5 It is vertically arranged, the upper surface of inner cylinder 4 and outer cylinder 5 flushes.It is respectively equipped on connecting plate 151 and 5 lateral wall of outer cylinder and inner cylinder 4 The floor 152(that inner sidewall is fixedly connected is referring to Fig. 1).Floor 152 strengthens the compactness that connecting plate 151 is connect with damper cylinder 2, Fixation is supported to outer cylinder 5 and inner cylinder 4, carries out buffer protection convenient for cabinet 1 of the damper cylinder 2 to headstock.

Referring to Fig. 2, inner cylinder 4, outer cylinder 5 and annular bottom plate 3 form toroidal cavity, and the buffering of annular is equipped in toroidal cavity Circle 6, bumper ring 6 is located on annular bottom plate 3.Bumper ring 6 is elastomeric material.Horizontal annular is equipped with above bumper ring 6 to hold Fishplate bar 8, annular bearing plate 8 are slidably connected with 4 lateral wall of inner cylinder and 5 inner sidewall of outer cylinder respectively, are equipped with above annular bearing plate 8 solid Fixed board 10,10 level of fixed plate are fixed in toroidal cavity.Above fixed plate 10 be equipped with receiving block 7, receiving block 7 respectively with inner cylinder 4 lateral walls and 5 inner sidewall of outer cylinder are slidably connected, and the top of receiving block 7 is higher than the top of inner cylinder 4 and outer cylinder 5.Receiving block 7 it is interior Side wall and lateral wall are equipped with vertical limit sliding chutes 13, and 4 lateral wall of inner cylinder and 5 inner sidewall of outer cylinder are equipped with limited block 14, limit Block 14 is nested in limit sliding chutes 13.Limited block 14 slides in limit sliding chutes 13, can limit the motion range of receiving block 7, It is not in make the case where top of receiving block 7 is lower than the top of inner cylinder 4 and outer cylinder 5 because being impacted, securely and reliably.

Referring to Fig. 2, be fixedly connected with vertical support rod 9 on annular bearing plate 8, support rod 9 pass through fixed plate 10 with it is upper The receiving block 7 of side is fixedly connected, and support rod 9 is slidably connected with fixed plate 10.When rotary drilling rig works, top of the drilling rod to cabinet 1 End pushes, and receiving block 7 bears the impact and vibration of drilling rod, the slide downward in toroidal cavity, due to the upper and lower ends of support rod 9 It is respectively fixedly connected with receiving block 7 and annular bearing plate 8, moves downward annular bearing plate 8, annular bearing plate 8 connects with bumper ring 6 Touching is pushed, and elastic deformation occurs for bumper ring 6, carries out damping, buffering to annular bearing plate 8.

Referring to Fig. 2, be arranged with damping spring 11 on support rod 9, damping spring 11 be located at receiving block 7 and fixed plate 10 it Between, the upper and lower ends of damping spring 11 are separately connected receiving block 7 and fixed plate 10.When receiving block 7 by drilling rod impact force to When lower movement, since 10 position of fixed plate is constant, the distance between receiving block 7 and fixed plate 10 reduce, and damping spring 11 is pressed Contracting, further progress damping, buffering.

Referring to Fig. 2, buffer spring 12 is also arranged on support rod 9, buffer spring 12 is located at fixed plate 10 and annular is accepted Between plate 8, the upper and lower ends of buffer spring 12 are separately connected fixed plate 10 and annular bearing plate 8.Buffer spring 12 makes fixed plate The distance between 10 and annular bearing plate 8 are relatively stable.When annular bearing plate 8 moves downward, annular bearing plate 8 and fixed plate The distance between 10 become larger, and buffer spring 12 is stretched, and generate elastic deformation, further progress buffering.In addition, damping spring 11 Bounce can be generated by being under pressure after compression with bumper ring 6, and during restoring deformation, damping spring 11 pushes receiving block 7 Rise, drives annular bearing plate 8 to rise by support rod 9；Bumper ring 6 is contacted with annular bearing plate 8, pushes annular bearing plate 8 Rise；The annular rising of bearing plate 8 can generate shock to fixed plate 10, cause to damage.Buffer spring 12 is in fixed plate 10 and annular It is buffered between bearing plate 8, avoids the impact damage between fixed plate 10 and annular bearing plate 8.

Referring to Fig. 2, support rod 9, damping spring 11 and buffer spring 12 are equipped with several, support rod 9,11 and of damping spring Buffer spring 12 is circumferential setting.It is circumferentially distributed, make to buffer more uniform, improves the effect of damping, buffering.Support rod 9 is to subtracting Shake spring 11 and buffer spring 12 have support and guiding role, make the damping spring 11 being set on support rod 9 and buffer spring 12 are stretched and are shunk along 9 direction of support rod, and it is horizontal inclined without generating preferably to carry out damping, buffering in the vertical direction It moves.

The implementation principle of above-described embodiment are as follows: when rotary drilling rig works, drilling rod pushes the top of cabinet 1, and receiving block 7 is held By the impact and vibration of drilling rod, the slide downward in toroidal cavity moves downward annular bearing plate 8, annular bearing plate 8 with it is slow 6 contact of punching circle is pushed, and elastic deformation occurs for bumper ring 6, carries out the first heavy damping, buffering to annular bearing plate 8.Receiving block 7 The distance between fixed plate 10 reduces, and damping spring 11 is compressed, and carries out the second heavy damping, buffering.Annular bearing plate 8 with it is solid The distance between fixed board 10 becomes larger, and buffer spring 12 is stretched, and generates elastic deformation, carries out third weight damping, buffering.It is triple to subtract The common cooperation of shake buffering, crushing resistance is high, and the huge vibration of drilling rod is greatly lowered with impact to damage caused by cabinet 1.In addition, Buffer spring 12 is buffered between fixed plate 10 and annular bearing plate 8, reduces damping spring 11 and bumper ring 6 is restoring Rebound during deformation avoids the impact damage between fixed plate 10 and annular bearing plate 8, securely and reliably.Limited block 14 It is slided in limit sliding chutes 13, the motion range of receiving block 7 can be limited, improve the safety of damper cylinder 2.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
