Abstract
The invention discloses a long-stroke multi-stage elevating device and method. The device comprises two or more stages of elevating barrels which are sleeved and connected in turn; a first stage elevating barrel is fixed; the other stages of elevating barrels descend in turn under the action of gravity from a second stage to a tail stage along the inner wall of a previous stage elevating barrel; a stroke length is detected in real time by adopting a stay guy displacement sensor to finish positioning; and in the ascending process, a steel wire rope fixedly connected to a tail section bottom plate drags a tail section elevating barrel upwards under the action of a hoist, and the other stages of elevating barrels gradually ascend under the supporting action of a stroke plate fixedly connected to a bottom plate of the tail section elevating barrel and return to initial state, so that the elevating process is finished.
Description
Technical field
The present invention relates to long travel multistage lifting device, relate in particular to the long travel multistage lifting device that can be applicable to long and narrow space.
Background technology
In the modern industry applied environment, long travel multistage lifting device is surveyed device support etc. in the oil gas exploratory shaft sinking has the occasion of harsh requirement all to be widely used to the strict restriction of jacking system oad to the stability of lifting process.Jacking system commonly used is cut slotting formula, feed screw nut's formula, hydraulic efficiency hinge formula.Yet, realize that three kinds of above-mentioned devices of lifting task of big stroke, little operating radius all have shortcoming, the restriction that the stroke of scissor-type is subjected to himself mechanism's physical dimension is difficult to realize long travel, and the whole anti-bending strength of scissor-type is relatively poor; Feed screw nut's formula is a single stage system, realize that long travel need grow the screw mandrel of size, but the screw mandrel difficulty of processing is big, and economy is bad; Need bigger working space when the hydraulic efficiency hinge formula rises work, be not suitable for long and narrow space.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and motion is steady, the long travel multistage lifting device of economical and efficient.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of long travel multistage lifting method, it is the lifting tube that two-stage and above socket successively link to each other, chopped-off head lifting tube top is fixed on the starting point place of forced stroke, lifting tubes at different levels descend until the order of final stage according to the second stage, the third stage along the inwall of upper class lifting tube separately respectively under the effect of gravity successively, to satisfy the requirement of the required stroke of its fastening, trip distance is measured by displacement pickup.The steel rope that is connected in during rising on the minor details base plate at first draws the rising of minor details lifting tube under the drive of elevator, all the other lifting tubes at different levels rise step by step under the support that is fixed on the stroke plate on the minor details lifting tube base plate and get back to initial condition, finish lifting process.
A kind of long travel multistage lifting device, comprise driving and stroke detection mechanism and the lifting tube that links to each other of socket successively more than the two-stage, remove the chopped-off head lifting tube top board and bottom guide ring are arranged, the final stage lifting tube has outside base plate and the top guide ring, the structure of lifting tubes at different levels is in full accord to be comprised: lifting tube, top guide ring and bottom guide ring, the parts of respectively forming of lifting tube constitute complete lifting tube by the mode of welding.
Described driving and stroke detection mechanism comprise drive motor, elevator, backguy displacement pickup, steel rope; Drive motor, elevator and backguy displacement pickup all are installed on the top board of chopped-off head lifting tube.
Compared with prior art, the invention has the advantages that:
Long travel multistage lifting method of the present invention can be regulated range by the quantity of increase and decrease lifting tube, this method economy, safety, reliable.Long travel multistage lifting device of the present invention adopts the multistage lifting jacket casing to connect continuous structure, it is little to take up room, motion steadily, the structure economic security, its biggest size of element is determined by the chopped-off head lifting tube, the auxiliary accuracy control that can realize stroke down at the backguy displacement pickup, because except that the chopped-off head lifting tube, the top guide ring of lifting tubes at different levels all cooperatively interacts with the inside face of upper class lifting tube, except that the final stage lifting tube, the bottom guide ring of lifting tubes at different levels all matches with the outside face of next stage lifting tube, so be subjected to the time spent of doing of horizontal exciting force when jacking system, this device has good bending resistance effect, guarantees that motion steadily.In the long travel multistage lifting device of the present invention, lifting tube structural similitudies at different levels, size difference to some extent only, compact overall structure is easy to make, I﹠M.

The specific embodiment
Fig. 1 shows the left view and the part sectional view of long travel multistage lifting device of the present invention, drive motor adapter plate 20 and bearing seat adapter plate 9 are welded on the top of chopped-off head lifting tube 10, drive motor 3 is installed on the drive motor adapter plate 20 by bolt, backguy displacement pickup 2, bearing seat 8 are installed on the bearing seat adapter plate 9, elevator 19 is installed on the motor shaft 4, pedestal cap 7 is installed on the bearing seat 8 by bolt, stroke plate 15 and tack 21 are installed on the base plate 17 of final stage lifting tube 14, and the end of pulling out of steel rope 18 and backguy 1 is installed on the tack 21.This device is according to second stage lifting tube 12 under the effect of self gravitation, the order of final stage lifting tube 14 descends successively, backguy displacement pickup 2 detects the real-time trip distance that stretches out to this device, when dropping to, stop drive motor 3, elevator 19 is no longer emitted steel rope 18, and this device stops to descend.When drive motor 3 drives elevator 19 contrarotations, elevator 19 is regained steel rope 18, steel rope 18 upwards promotes final stage lifting tube 14 by tack 21, final stage lifting tube 14 is upward movement at first, when the stroke plate 15 that is fixed on final stage lifting tube base plate 17 with after lifting tube 12 bottoms in the second stage contact, stroke plate 15 will drive second stage lifting tube 12 with final stage lifting tube 14 upward movements, return in the chopped-off head lifting tube 10 until all the other lifting tubes at different levels except that chopped-off head lifting tube 10 successively by order from final stage lifting tube 14 to second stage lifting tube 12, when rising puts in place, stop drive motor 3, finish uphill process.
