Description
Technical field
The utility model is related to oil extraction in oil field field of engineering technology, more particularly to a kind of freely to adjust lifting bridge chair.
Background technology
When oil pipe (sucker rod) bridge chair is that oil pipe, sucker rod ground are put, oil pipe, sucker rod is made not to land and plays support and makees
Tool.Current existing bridge chair has the following disadvantages：First, regulation pipe (bar) bridge level goes pipe lift expense is adjusted again
When it is laborious；Once pipe (bar) bridge enters use and cannot be adjusted again, during for well-mouth operating floor bearing, adjusting operation console
Balance is all carried operation panel and crossbeam etc. off to be adjusted, then crossbeam and operation panel are installed in place to rotate bridge chair screw rod.
It readjusts also to carry operation panel and crossbeam off if necessary and carrys out repetitive operation, time-consuming and laborious, operation is very inconvenient.
Invention content
Technical problem to be solved in the utility model is to overcome existing bridge chair present in background technology that cannot freely adjust
The problem of time-consuming and laborious is saved, and a kind of freely adjust is provided and lifts bridge chair, this freely adjusts lifting bridge chair, can pass through to rotate and adjust
Tubing string on section lift nut bridge chair carrys out regulation pipe (bar) bridge level, convenient and time-saving laborsaving.
The invention for solving the technical problem can reach by following technical solution：This freely adjusts lifting bridge chair, including
Bottom plate, the bottom plate upper vertical connect support tube, and support tube top inner wall connects leading screw, leading screw lower end by locking nut
Opposite direction support bottom of the tube, leading screw upper end is fixedly connected with U-shaped trustship；Pipe outer wall connection fixing nut is supported, in fixing nut upper end
It is threadedly coupled adjusting nut external screw thread, adjusting nut internal thread connection leading screw, adjusting nut top both sides connection handle.
The utility model can have the advantages that compared with above-mentioned background technology：Lift bridge is freely adjusted using this
Tubing string is placed on the tubing string that can be lifted in the U-shaped trustship for freely adjusting lifting bridge chair by rotating adjusting nut on bridge chair by seat
Carry out regulation pipe (bar) bridge level, it is convenient and time-saving laborsaving.Manage (bar) bridge pipe due to soft sinking in ground etc. in use
Bridge can become not usually, can adjust pipe bridge level with can be manually rotated handle.In addition this freely adjust lifting bridge chair can be in crossbeam
Cooperation under freely adjusts lifting bridge chair using four and realizes that well-mouth operating floor is freely lifted, can facilitate the completion side of beating clamp and
The operation that well head removes when hanging polished rod eye and excessively high well head.This freely adjusts lifting bridge chair reasonable design, is easy to maintain；Regulation pipe
Bridge is more horizontal, time saving and energy saving.After the completion of freely adjusting lifting bridge chair development, it is applied to 40 mouthfuls of wells in 1 year in job execution altogether,
See good effect.
Description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
In figure：1st, bottom plate, 2, support tube, 3, gusset, 4, fixing nut, 5, nylon jacket, 6, adjusting nut, 7, lock
Tight nut, 8, handle, 9, leading screw, 10, U-shaped trustship.
Specific embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, this freely adjusts lifting bridge chair, including bottom plate 1,1 upper vertical of the bottom plate connection support
Pipe 2, is fixedly connected with gusset 3 between 2 two bottom sides of support tube and bottom plate 1,2 top inner wall of support tube is connected by locking nut 7
Leading screw 9 is connect, 9 lower end opposite direction support tube of leading screw, 2 bottom, 9 upper end of leading screw is fixedly connected with U-shaped trustship 10；The connection of 2 outer wall of support tube is solid
Determine nut 4,4 upper end internal thread connection 6 external screw thread of adjusting nut of fixing nut, 6 internal thread of adjusting nut connection leading screw 9 is adjusted
6 top both sides of nut connect handle 8；Nylon jacket 5 is equipped between fixing nut 4 and adjusting nut 6, nylon jacket 5 can effectively improve
Turncap mobility.
Embodiment one：Realize that quick adjusting pipe bridge is horizontal
Bridge chair is first placed on designated position, then tubing string is placed in the U-shaped trustship for freely adjusting lifting bridge chair, passes through rotation
Tubing string on handle hand lifting bridge chair carrys out regulation pipe (bar) bridge level, carrys out repeated multiple times adjusting bridge chair without tubing string is carried off, and one
It is secondary to adjust level, it is convenient and time-saving laborsaving and accurate.
Embodiment two：Realize the adjusting to pipe (bar) bridge at any time
When pipe (bar) bridge, pipe bridge can become uneven due to soft sinking in ground etc. in use, original lifting bridge chair
At this moment it can not have adjusted again.Freely adjust lifting bridge chair at this moment can be manually rotated handle adjust again pipe bridge level.
Embodiment three：Realize that well head is freely lifted the use of operation console
Lifting bridge chair realization well head operation can freely be adjusted under the cooperation of crossbeam using four by freely adjusting lifting bridge chair
Platform is freely lifted, and well head when completing the side's of beating clamp with hanging polished rod eye and excessively high well head can be facilitated to remove operation.
