2, the utility model is by installation position displacement sensor on each hydraulic jack, and further mounted angle sensor on storage tank, can realize respectively the real-time detection of the degree of dip in lifting process to the lift height of each hydraulic hoisting machine and storage tank, and by showing that controller shows, thereby effectively monitored whole lifting process, and can carry out accordingly in good time height adjustment, so just more guaranteed the synchronous and steady of storage tank lifting process, and the safety performance that has improved hydraulic pressure lift.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of storage tank hydraulic jacking device.
In figure: hydraulic control system 1, hydraulic hoisting machine 2, lifting arm 3, loose cassette hydraulic jack 4, piston rod 5, guide rail 6, slipper bracket 7.
The specific embodiment
As shown in Figure 1, a kind of storage tank hydraulic jacking device, comprise hydraulic control system 1 and a plurality of hydraulic hoisting machine 2, hydraulic hoisting machine 2 comprises raising legs, lifting arm 3 and loose cassette hydraulic jack 4, the piston rod 5 of pine cassette hydraulic jack 4 is hollow structure, lifting arm 3 intercalations are in piston rod 5 hollow, raising legs comprises guide rail 6 and slipper bracket 7, and slipper bracket 7 is connected with lifting arm 3, above-mentioned a plurality of hydraulic hoisting machine 2 is by the unified fuel feeding of hydraulic control system 1, and when lifting storage tank, slipper bracket 7 is being lifted the packing that is fixed on reservoir walls and is being slided up and down along guide rail 6.
In specific works process, by hydraulic control system 1 is unified, control, make loose cassette hydraulic jack 4 oil-feeds, the upper chuck of its piston rod 5 clamps and lifts lifting arm 3 and packing, thereby drives storage tank upwards to promote; When 4 oil return of loose cassette hydraulic jack, its upper chuck is with piston rod 5 backhauls, and now its lower dop automatic clamping lifting arm 3 can not glide it.Pine cassette hydraulic jack 4 so repeatedly motion makes lifting arm 3 constantly rise with tank body, until predetermined height.Instantly after one deck wallboard docking assembly welding, open the upper and lower loose card device of loose cassette hydraulic jack 4, unclamp upper and lower dop lifting arm 3 and packing are dropped to swelling behind lower one deck wallboard bottom, weld power transmission gusset, then promote.So repeatedly make the storage tank tank body that assembly welding is good increase, to the last one deck wallboard assembly welding completes.For above-mentioned storage tank hydraulic jacking device, a plurality of hydraulic hoisting machines 2 are wherein uniformly distributed along reservoir walls, and the maximum lift weight-matched of the number of hydraulic hoisting machine 2 and storage tank.For hydraulic control system 1, can adopt various ways of the prior art to realize the control to each loose cassette hydraulic jack 4 completely.
By adopting said structure, can effectively realize following technique effect:
1) storage tank tank body promotes steady, safety, reliable: because the performance of each loose cassette hydraulic jack 4 is approaching, and adopt hydraulic control system 1 to unify fuel feeding control, make hoisting speed more consistent with synchronism, thereby whole lifting process is more steady.And the self structure feature of loose cassette hydraulic jack 4 has determined that its self-locking property is good, not can because of have a power failure or lifting process in need to stop liter to repair and cause tank body to glide or tenesmus, thereby make whole lifting process safe and reliable;
2) greatly guaranteed construction quality: hydraulic pressure lift construction must adopt packing swelling wallboard, so its circularity is good, wallboard circumferential weld group to time easy centering; Under the effect of packing, the rigidity of wallboard increases greatly, and the welding contraction distortion of circumferential weld is little, and planeness is good; And loose cassette hydraulic jack 4 can also be controlled more accurately by the hoisting depth that edges down.Therefore, the construction quality of storage tank tank body is guaranteed;
3) equipment convenient operation, work efficiency is high: storage tank hydraulic jacking device up-to-dateness is high, and convenient operation, thereby has greatly alleviated workmen's labour intensity, has improved operating efficiency;
4) duration is short, cost is low, good in economic efficiency: the hoisting speed of storage tank hydraulic jacking device is fast, and the clean lifting time of one deck wallboard (being highly 1.8-2.2m), only for 20-30min, can effectively speed up the work, and shortens the construction period; High-rise working changes Ground Operation into, can save the expense of crane and scaffold, and the operating personal needing is few, can save labour cost.
As a kind of preferred, above-mentioned storage tank hydraulic jacking device is also respectively equipped with the displacement pickup for detection of its lift height on each loose cassette hydraulic jack 4, and the mouth of displacement pickup is connected with the input end that shows controller, and further, obliquity sensor is also installed on storage tank, and the mouth of obliquity sensor is also connected with the input end that shows controller.Like this, by displacement pickup and obliquity sensor, just can realize respectively the real-time detection of the degree of dip in lifting process to the lift height of each hydraulic hoisting machine 2 and storage tank, and by showing that controller shows, just can effectively monitor whole lifting process, and can to the lift height of each hydraulic hoisting machine 2, adjust accordingly in good time, thereby more guaranteed the synchronous and steady of storage tank lifting process, and the safety performance that has improved hydraulic pressure lift.
By reference to the accompanying drawings the preferred specific embodiment of the utility model and embodiment are explained in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken possessing those skilled in the art, can also make without departing from the concept of the premise utility various variations.
