Description
Technical field
The utility model relates to oil drilling and extracting equipment technical fields, and in particular to one kind pulls workover rig derrick adjustment device
And pull workover rig.
Background technique
Currently, the derrick for pulling workover rig is needed to positive wellbore center, the cover off of derrick can pass through towed vehicle
Back-and-forth motion is adjusted, and operation is relatively simple, but steering wheel is beaten to just needing to carry out towed vehicle left and right in the left and right of derrick
And cooperate advance and reversing to be adjusted, entire adjustment process can not accurate contraposition, in addition to driver driving technology requirement
It is also time-consuming except higher.The front-rear direction of derrick refers to that the extending direction of towed vehicle, the left and right directions of derrick refer to towed vehicle
Two sides extend direction.
Utility model content
Workover rig derrick adjustment device is pulled the purpose of this utility model is to provide one kind and pulls workover rig, with solution
Certainly existing derrick for pulling workover rig or so is to just inaccurate problem.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
One kind pulling workover rig derrick adjustment device, comprising: two-way cylinder and the pendulum for being respectively placed in two-way cylinder both ends
Dynamic device；Pendulous device passes through shift fork and the both ends of two-way cylinder connect；
Pendulous device includes mounting base, the sliding axle being set in mounting base and is sheathed on sliding axle and is used to support well
The carrier block of frame；The extending direction of sliding axle and the direction of action of two-way cylinder are consistent, and sliding axle is slidably matched with carrier block；It dials
2 divergent ends of fork are connect with carrier block, and the polymerization end of shift fork is connect with two-way cylinder.
The piston rod at the utility model two-way cylinder both ends can be in the same direction and be moved synchronously, i.e. the piston rod elongation of one end
When, the piston rod of the other end is shunk, and extends consistent with the speed shunk, and makes the pendulous device at two-way cylinder both ends in the same direction simultaneously
And move synchronously, guarantee that the distance between 2 pendulous devices are constant, guarantees that the derrick on pendulous device is put with pendulous device or so
It is dynamic, to adjust derrick location in left and right directions, make derrick to positive wellbore center.Carrier block is used to support derrick, and can be with
It is slided on sliding axle, behind the outside of carrier block and the divergent ends connection of shift fork, makes carrier block by power of two-way cylinder or so
Symmetrically, it prevents stuck between carrier block and sliding axle.Meanwhile carrier block forced position separates, and improves itself and shift fork contact position
Stress, prevent shift fork from falling off from carrier block.Since two-way cylinder is hydraulic operation, the power externally exported is larger, hydraulic dynamic
It is more steady to make the lower movement for making pendulous device of speed, derrick can accurately carry out a left side in the movement with pendulous device
The right side is and time saving and energy saving to just.

For the connecting plate of the utility model for connecting mounting base and carrier block, pin shaft can be in the strip-shaped hole on connecting plate
It slidably reciprocates, with the movement of two-way cylinder, connecting plate can limit the position of carrier block by strip-shaped hole, make carrier block in item
It horizontally slips between the position of shape hole limitation, prevents carrier block from excessively moving and skid off sliding axle and derrick is caused the accidents such as to fall
Occur.
Further, above-mentioned mounting base includes bottom plate and 2 pieces and bottom plate support plate connected vertically；Bottom plate and connecting plate
Hingedly；2 pieces of support plates are oppositely arranged and connect respectively with the both ends of sliding axle.
Further, above-mentioned it is characterized in that, sliding axle be splined shaft；The middle part of carrier block, which is equipped with, to be cooperated with splined shaft
Splined hole.
The sliding axle and carrier block of the utility model are attached by spline, are then slided by spline, are increased
Contact area between sliding axle and carrier block, junction when the gravity center instability of derrick, between sliding axle and carrier block
It will not be crushed due to gravity, so that derrick be avoided to collapse because of gravity center instability.
One kind pulling workover rig, comprising: towed vehicle, bracket, derrick and above-mentioned workover rig derrick of pulling adjust device；It drags
Trailer, bracket are pulled workover rig derrick adjustment device, derrick and are set gradually from top to bottom；Pull workover rig derrick adjustment device
Extending direction it is vertical with the extending direction of towed vehicle.
The utility model pulls workover rig with towed vehicle as final bearing mode, and the front and back of derrick is adjusted by pulling
Vehicle simply advances and moves backward to realize, the left and right adjusting of derrick is realized by two-way cylinder.Derrick it is whole to positive regulator
Fairly simple, accuracy is higher, the time needed for having saved manpower and material resources and having adjusted.
Further, the upper end of above-mentioned bracket is equipped at least two side by side and pulls workover rig derrick adjustment device；Bottom plate and double
To oil cylinder respectively be fixedly connected at the top of bracket.
The utility model pulls workover rig derrick adjustment device by least two to support derrick, improves the stabilization of derrick
Property, it is multiple pull workover rig derrick adjustment device in the same direction, move synchronously, it is common to adjust the position of derrick in left and right directions.
The utility model has the following beneficial effects:
(1) the utility model by the pistons of two-way cylinder two sides in the same direction, synchronize and moved, drive derrick or so to move
