Abstract
A top drive back-up tong torque arm system mainly comprises an outer torque arm, a lifting motor, a lifting gear, racks, an inner torque arm, a back-up tong device and a suspension damping device and the like. The suspension damping device is installed in the inner torque arm, the weight of the back-up tong device and the inner torque arm acts on the outer torque arm through a suspension damping effect through a connecting pin, so that impact force on back-up tongs caused by vertical movement of top drive and an upper shackle is buffered through the suspension damping device, and the damage to a device is reduced. The racks are fixed to the two sides of the inner torque arm and installed on the two sides of the outer torque arm, and the racks and the lifting gear perform matching action. The lifting motor drives the racks to move up and down through the lifting gear, the inner torque arm and the back-up tongs move up and down accordingly, and the adjustment of different working heights of the back-up tongs is performed. The top drive back-up tong torque arm system is simplified in structure, functions are improved, the impact to the device is reduced, the production efficiency is improved, and manpower and material resources are saved.
Description
Technical field
The present invention relates to one and can carry high pulling torque, can automatic lifting be applied to push up the back-up tong torque arm system driven.
Background technology
At present, the back-up tong torque arm system in domestic and international top drive drilling system, it is intended only as the clamping device of pipe processor system, can transmit, bear the moment of torsion that shackle on back-up tong is brought, structure is the heaviest, complicated, and the volume of each part, weight are the biggest；Upper, need to utilize other equipment artificial mobile back-up tong when unloading upper and lower preventer and protection joint, back-up tong is heavier, mobile has any problem；This just replaces with lower preventer to scene and brings certain difficulty, reduces work efficiency.
Summary of the invention
The present invention proposes a kind of top and drives by back-up tong torque arm system, to improve production efficiency, uses manpower and material resources sparingly.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of top is driven by back-up tong torque arm system, and including back-up tong device, it includes outer torque arm and internal torque arm, between the two gap suit；Described internal torque arm lower end and back-up tong device are affixed；Tooth bar is installed on the both sides of internal torque arm, promotes motor and is arranged on the outer torque arm both sides with tooth bar homonymy, promotes and installs lifting gear on the power transmission shaft of motor；And promote wheel and rack engaged transmission.
In described internal torque arm, damping device is installed.
Described damping device is made up of link, spring and guide post；Installing guide post on this link, pocketed springs on this guide post, this spring is in Pre strained state；Damping device is hung up by the connecting pin being arranged in outer torque arm through the hole bottom link.
Described outer torque arm and inside and outside torque arm are rhs-structure.
Beneficial effects of the present invention has:
1, inside and outside torque arm uses square tube sleeve structure, utilizes simple structure, ingenious employing square torque arm cross sectional shape, the transmission of moment of torsion when solving back-up tong work.
2, motor and the use of rack-and-pinion are promoted so that the automaticity of back-up tong device improves, and improves production efficiency, uses manpower and material resources sparingly.
3, the design of damping device so that top is driven and moved up and down and the impulsive force of back-up tong is buffered by upper shackle, decreases the impact to equipment and infringement.
Accompanying drawing explanation
Fig. 1 is the main body package assembly schematic diagram of the present invention；
Fig. 2 is the B-B profile in Fig. 1；
Fig. 3 is that the A in Fig. 1 is to figure.
In figure: 1 outer torque arm, 2 lifting motors, 3 lifting gear, 4 tooth bars, 5 internal torque arms, 6 back-up tong devices, 7 keys, 8 bolts, 9 links, 10 connecting pins, 11 springs, 12 guide posts.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1,2,3, a kind of top is driven by back-up tong torque arm system, including outer torque arm 1, lifting motor 2, promotes gear 3, tooth bar 4, internal torque arm 5, back-up tong device 6, key 7, bolt 8, link 9, connecting pin 10, spring 11, guide post 12.Gap suit between outer torque arm 1 and the internal torque arm 5 of this system；Described internal torque arm 5 is L-type structure, lower end and back-up tong device 6 that this L-type is long-armed connect fixing by bolt 8, and the upper surface of L-type galianconism is by positioning with the upper break-out torque of transmission bottom key 7 and back-up tong device 6, the structure of outer torque arm 1 herein is open, i.e. has gap on the rhs-structure at this.Tooth bar 4 is installed on the both sides of internal torque arm 5, promotes motor 2 and is arranged on outer torque arm 1 both sides with tooth bar 4 homonymy, promotes and installs lifting gear 3 on the power transmission shaft of motor 2；And promote gear 3 and tooth bar 4 engaged transmission.Promoting the motor 2 band carry-over bar 4 that operates when moving up and down, internal torque arm 5, back-up tong device 6 move up and down therewith, it is achieved that the regulation of the working depth that back-up tong is different.Outer torque arm 1 upper end is fixed on revolving body by bearing pin, bolt.
Being provided with damping device in described internal torque arm 5, this damping device is made up of link 9, spring 11 and guide post 12；Installing guide post 12 on this link 9, pocketed springs 11 on this guide post 12, this spring 11 is in Pre strained state；Damping device is hung up by the connecting pin 10 being arranged in outer torque arm 1 through the hole bottom link 9.Thus the damping device that the weight of back-up tong device and internal torque arm 5 passed through to hang is acted in outer torque arm 1.So top is driven and is moved up and down and upper shackle is all to the impulsive force that back-up tong is the biggest, first passes around the buffering of spring, decreases the injury to equipment.
Described outer torque arm 1 and inside and outside torque arm 5 are rhs-structure, can effectively transmit the moment of torsion that back-up tong work produces.
Back-up tong device 6 uses cuboid, miniaturization structure, forging.
