Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but is not that model is protected to the utility model
The limitation enclosed.
A kind of steel truss hydraulic lifting system, including 4 jack, 2 oil pump stations and a computer controlling center,
As shown in figures 1 to 6, jack is used for lifting heavy 7, each jack be equipped with upper anchor head 5 and lower anchor head 6 and
Through upper anchor head 5 and the steel strand wires 4 of lower anchor head 6, lower anchor head 6 is fixed on 1 bottom of jack supporting rack by anchor head oil cylinder 9 once
Portion, upper anchor head 5 are fixed on mandril of lifting jack 2 by anchor head oil cylinder 8 on one, and weight 7 is fixed on 4 bottom of steel strand wires；
The oil pump station is used to give jack fuel feeding；
The computer controlling center is used for control oil pump station and jack acts.
Jack is 350 tons of jack, steel strand wires 4 using it is high strength low relaxed it is pre- answer pulling force steel strand wires, quantity is 25,
Its nominal diameter 15.24mm, tensile strength 1860N/mm, rupture pull force 260.7KN, minimum lotus of the elongation at 1%
Carry 221.5KN, elasticity modulus 198Gpa, relaxation Shuai≤2.5%, every meter of weight 1.1Kg.Steel strand wires 4 are divided to for left-handed and two kinds of dextrorotation
Specification, oppositely oriented per adjacent two steel strand wires 4, steel strand wires 4 stretch out 0.5 meter of jack.Mandril of lifting jack 2 is L-shape, and thousand
Jin topmast support 1 is equipped with the sliding slot 3 for coordinating mandril of lifting jack 2.
When the utility model assembles, jack is vertically disposed in lifting platform, is fixed with bolt or seven word otic placodes, carried at the same time
There is steel strand wires mounting platform under peaceful platform.The anchorage up and down of jack is opened, every steel strand wires should be checked conscientiously before penetrating
Whether steel strand wires cut place meets the requirements, according to status requirement of the steel strand wires in jack, one by one by every steel strand wires from dredging
The boosted platform of guide plate penetrates oil cylinder, after steel strand wires stretch out, is individually stepped up with U-clamp, after confirmation is errorless, slowly comes loose, until
Confirm that steel strand wires will not glide, then wear one, after the completion of all steel strand wires penetrate, pin anchorage, U-clamp up and down and be not allowed to solve
Remove, mark is carried out according to oil cylinder position on plate is dredged, while the steel strand wires of bottom two are clamped with U-clamp, plate will be dredged along steel
Twisted wire is made in order from top to bottom, then installs lower anchor head, notices that lower anchor head direction is consistent with oil cylinder direction, whole installation process is made sure to keep in mind
Steel strand wires safety, whole construction site penetrate into from steel strand wires and remove tight welding job, damaged to prevent steel strand wires caused by energization
Wound.
Steel strand wires pretension：
Steel strand wires penetrate oil cylinder, and jack lifts in place, and lower anchor head will carry out steel strand wires pretension work after installation is complete,
Pretension is carried out using 1 ton of bottle gouard moved by hands, using falsework, steel strand wires is tensioned by root, if U-clamp clamps a steel strand wires, U
Clevis is not allowed to release, if U-clamp clamps several steel strand wires, first can open U-clamp, after the completion of pretension, U-clamp be recovered, in advance
During tight, someone is not allowed at lower anchor head.
The operation principle of jack：
The lower anchor head of jack is fixed on lifting bracket together with jack supporting rack, and upper anchor head is then fixed on jack top
On bar, it can move up and down with mandril of lifting jack.
The action process of jack：1st step：Anchor head clamps in upper anchor head hydraulic oil cylinder driving, clamps steel strand wires (such as Fig. 1 institutes
Show)；2nd step：Anchor head unclamps under a hydraulic oil cylinder driving of casting anchor, and mandril of lifting jack jacks up lifting heavy (as shown in Figure 2)；3rd step：Under
Anchor head hydraulic oil cylinder driving is casted anchor head clamping, clamps steel strand wires (as shown in Figure 3)；4th step：Mandril of lifting jack micro, upper anchor head oil cylinder
Anchor head is unclamped in driving disengages (as shown in Figure 4) with steel strand wires；5th step：Upper anchor head rises, and upper anchor head is complete loose (as shown in Figure 5)；
6th step：Mandril of lifting jack drives upper anchor head to retract (as shown in Figure 6) in situ, and then progress next round clamps steel strand wires and drives weight
Thing rises.
After jack stretches cylinder in place, tightly cast anchor, Song Shangmao, carries out contracting steel, can return to initial position and be carried next time
Rise.Opposite action process can then realize the decline of weight.The each stroke of jack is 250mm, and lifting speed is about 4-
6m/h。
The utility model is by the action of computer controlling center control oil pump station and jack, it can be achieved that hydraulic synchronization carries
Construction technology is risen, is controlled by stroke and displacement sensing monitoring and computer, data feedback and control instruction transmission can be full-automatic
Realize that synchronization action, load balancing, posture correction, Stress Control, operation locking, process are shown and a variety of work(such as fault alarm
Energy.
Operating personnel can carry out hydraulic pressure lift in central control room by hydraulic synchronization computer control system man-machine interface
The observation of process and related data and (or) the issue of control instruction.
One computer controlling center controls four 350T jack respectively by two oil pump stations.
Jack is controlled by load equilibrium mode in overall lifting process, is only seen in principle for relative displacement
Survey, do not adjust；But if the relative displacement of four hoist points is more than 30mm, it should be adjusted.
Since this time is promoted to computer control, participated in without excessive personnel, but personnel are also needed at each node lifted
It is monitored, to ensure the security of lifting, need to be monitored in following parts-layout personnel：
One lifting commander in chief, collects information in lifting process, so as to the correct order of the number of hair, a computer operation at any time
Personnel, four jack monitoring personnels, two pumps station personnel, need four workers to follow lift structure to carry out in lifting process
Monitoring, each need to respectively arrange interface one worker, and when truss is reached to interface, it is dry whether monitoring original structure bracket has
Disturb, four survey crews need to be arranged interface two sides to be observed, needed in lifting process stress monitoring personnel to lift structure into
Row monitoring, all personnel related with lifting need to respectively be equipped with an intercom and two pieces of batteries, such as occur at respective monitoring different
Become, should notify commander in chief at once, ensure lifting safety.It should be numbered before lifting in each operating position, with eye-catching number
Word is labeled, so that commanding can understand information everywhere.
After truss lifting in place, the operating platform made in advance is placed in position, arrangement personnel carry out the tune to interface
Section.
To ensure the security of lifting, measure for improvement need to be checked and checked and accepted, particular content is shown in inspection record table.
Computer controlling center, oil pump station and jack in the utility model are the conventional equipment of market buying, therefore
Concrete structure and connection are not stated carefully.
