Abstract
The utility model relates to a rotary power head connecting structure which comprises a reduction box, a carriage assembly and a connecting board connecting the reduction box with the carriage assembly. The rotary power head connecting structure is characterized in that a vibration reduction sleeve is arranged in a vertical pin sleeve of the connecting board and is composed of an outer sleeve, a rubber sleeve and an inner sleeve, an upper lug seat of the carriage assembly is provided with an upper vibration reduction board, a lower lug seat of the carriage assembly is provided with a lower vibration reduction board, the vertical pin sleeve of the connecting board is arranged between the upper lug seat and the lower lug seat of the carriage assembly and is connected through a connecting pin, and a bond strap is additionally arranged between the upper lug seat of the carriage assembly and the connecting board. The rotary power head connecting structure is simple, easy to manufacture, convenient in installation and connecting and good in reliability; vibration of a machine is effectively reduced through the vibration reduction sleeve, the fatigue resistance, vibration absorption performance, impact resistance, self-lubrication performance and corrosion resistance are good, friction between the carriage assembly and the connecting board is reduced, the vibration reduction and noise reduction effects are good, and by means of the bond strap additionally arranged between the upper lug seat of the carriage assembly and the connecting board, the reliability and safety of the connecting structure are improved.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, is specifically related to a kind of rotary power head syndeton of rotary drilling rig.
Background technology
Balladeur train assembly on existing rotary digging drill power head is connected by junction plate with unit head reduction box; And junction plate adopts the perpendicular pin of metal to be connected with balladeur train assembly.This connected mode, because rotary digging drill power head device slides up and down at mast, drive sleeve drive on deceleration box is simultaneously got rid of soil dish and is rotated, junction plate erects pin with being connected of balladeur train assembly and therefore bears horizontal and vertical larger power, when rotary drilling rig work, vibration is large, bindiny mechanism easily damages, and work noise is large simultaneously.When high pulling torque is exported in addition, the perpendicular guide on the upper lower ear base on balladeur train and junction plate produces larger impact shock and noise, and perpendicular guide easily weares and teares.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that above-mentioned technology exists, and a kind of simple in structure, rotary power head syndeton of vibrating long, good work environment of little life-span is provided.
The rotary power head syndeton that this reality is novel, comprises reduction box, balladeur train assembly and is connected the junction plate of reduction box, balladeur train assembly, it is characterized in that: in the perpendicular guide of described junction plate, be built-in with shock-reducing sleeve; Described shock-reducing sleeve is made up of overcoat, rubber sleeve and inner sleeve; The upper ear seat of described balladeur train assembly is provided with damping block, and lower ear base is provided with lower damping block; The perpendicular guide of junction plate is placed between the upper ear seat and lower ear base of balladeur train assembly, and is connected by connecting pin.
In order to improve the safety of syndeton:
Between the upper ear seat of described balladeur train assembly and junction plate, have additional ground strap, the two ends of ground strap respectively by bolt tightening on upper ear seat and junction plate.
The utility model is simple in structure, easy to manufacture, and good reliability easy to connect is installed; Effectively the decay vibration of machine self of shock-reducing sleeve, endurance, absorbing, shock resistance, self-lubricating and good corrosion resistance; Reduce the friction between balladeur train assembly and junction plate, effectively reduce noise, improved working environment, between the upper ear seat of balladeur train assembly and junction plate, have additional ground strap, improve reliability and the safety of syndeton, when especially high pulling torque is exported, vibration damping and excellent noise reduction effect.

Fig. 1 is syndeton schematic diagram of the present utility model.
In figure: 1, upper damping block, 2, shock-reducing sleeve, 3, ground strap, 4, lower damping block, 5, balladeur train assembly, 6, junction plate, 7, reduction box, 11, perpendicular guide, 12, upper ear seat, 13, connecting pin
,14, lower ear base.
Detailed description of the invention
The rotary power head syndeton that this reality is novel, comprises reduction box 7, balladeur train assembly 5 and is connected the junction plate 6 of reduction box 7, balladeur train assembly 5.Shock-reducing sleeve 2 interference fits are pressed in the perpendicular guide 11 of junction plate 6.Shock-reducing sleeve 2 is made up of overcoat, rubber sleeve and inner sleeve, and jacket and inner sleeve metal is made.The upper ear seat 12 of balladeur train assembly 5 is provided with damping block 1, and lower ear base 14 is provided with lower damping block 4, and upper damping block 1 and lower damping block 4 are made up of nylon.The perpendicular guide 11 of junction plate 6 is placed between the upper ear seat 12 and lower ear base 14 of balladeur train assembly 6, and connecting pin 13 is successively through shock-reducing sleeve 2 and lower ear base 14 in upper ear seat 12, perpendicular guide 11, and junction plate 6 is connected by connecting pin 13 with balladeur train assembly 5.
Erect shock-reducing sleeve 2 built-in in guide 11 and upper damping block 1 and lower damping block 4 and effectively reduce the vibration and the noise that impact generation, effect of vibration and noise reduction is good, improves working environment.
