Abstract
The utility model relates to a hydraulic lifter which can increase the lifting height of lifting type object to two times of the self lifting height, the self height of the utility model relates to 1.5 m, and a tank wall plate can be increased to 2 m. The utility model is mainly composed of a hydraulic cylinder, a sliding sleeve, a lifting scaffold head, a lifting rigging, a base and a hydraulic station and is mainly suitable for the flip chip construction of cylindrical metal tanks. Under the condition of using a hydraulic cylinder as lifting power, the utility model can avoid the top opening when installing the metal tanks, so the utility model has smaller volume, simple structure and manufacturing technique, and the utility model is suitable for field use.
Description
The utility model relates to the metal can hydraulic hoisting machine that uses in a kind of surface construction construction, particularly a kind of cylindrical metal jar upside-down construction hydraulic hoisting machine that is applicable to.
Utilize the construction of round metal tubular storage tank inversion method that a variety of methods are arranged at present, hydraulic hoisting machine is used more and more widely in recent years, the hydraulic hoisting machine that existing hydraulic pressure lift method adopts has three kinds of forms substantially: a kind of is that the earrings of cylinder plunger and rising arm are linked up, hook the working packing of storage tank with rising arm, driving the casing wall plate by bearing plate rises, second kind is to adopt self-locking feed-through hydraulic jack, drive lifting arm and promote gib head, hook packing and tank shell and rise.These two kinds of gigs itself highly all are higher than a joint tank shell height, therefore, when promoting first segment tank shell and tank deck, must each all opens a hole corresponding to the position that gig is installed in tank top.The third hydraulic hoisting machine is to adopt the twin-stage cylinder to replace single-stage cylinder in above-mentioned two kinds of methods.Though made the device reduced height like this, the liquid tooth mug is thicker, and structure and manufacturing process be more complicated also.
The purpose of this utility model is that a kind of stroke amplifying type hydraulic hoisting machine will be provided, its height (about 1.5m) own is lower than the height of a joint tank shell (1.6m-2.0m), but can promote tank shell and reach the 2.0m height, so both adopted the simple single stage hydraulic cylinder of structure, avoid the perforate of big tank top again, dwindled the volume of hydraulic hoisting machine.
The utility model is realized in the following way: it is made up of hydraulic cylinder piston rod (1), raising legs head (2), rigging (3), support (4), sliding sleeve (5), Hydraulic Station (6), base (7), hydraulic cylinder (8) base plate (9), tank skin (10), packing (11), hanger (12), bearing plate (13).The raising legs head (2) that hydraulic cylinder piston rod (1) and one are enclosed within the sliding sleeve (5) on the hydraulic cylinder body and are fixed on sliding sleeve (5) top is associated in together, one end of hydraulic cylinder (8), Hydraulic Station (6) and lifting rigging (3) is fixed on this machine base (7), during work, along with sliding sleeve (5) and raising legs head (2) by piston rod (1) jack-up, then stride across raising legs head (2), one end is fixed on the base (7), and the other end is fixed on steel rope on packing (11) and the tank shell (1) also along with motion.When sliding sleeve (5) and raising legs head (2) during by liquid presses piston pole (1) jack-up certain altitude, then the rope hoisting that connected with it of packing (11) and tank body rises twice highly to hydraulic stem (1), has promptly realized the stroke amplification.
This machine is because the structure that has adopted hydraulic cylinder piston rod (1), raising legs head (2), rigging (3), sliding sleeve (5), base (7), hydraulic cylinder (8), tank skin (10), packing (11) to form, make the about 1.5m of hydraulic compressor bottom-to-top-height, height will reach 2.5m (hydraulic stem rises 1m) during work, can promote the 2m height to metal can.This body is long-pending less, and structure and manufacturing process are also fairly simple, is well suited for on-the-spot the use.
Fig. 1 is a metal can stroke amplifying type hydraulic hoisting machine constructional drawing front elevation;
Fig. 2 is a metal can stroke amplifying type hydraulic hoisting machine constructional drawing right elevation;
Below in conjunction with accompanying drawing the utility model is further described.
The hydraulic actuating cylinder 8 of this machine, one end of Hydraulic Station 6 and lifting rigging 3 is fixed on this machine base 7, during use, base 7 must be fixing with metal can base plate 9, for preventing that hydraulic cylinder 8 from tilting, also hydraulic cylinder 8 tops and metal can base plate 9 are fixing once more with two supports 4, behind Hydraulic Station 6 power connections, the direct motor drive Hydraulic Pump, pass through by pass valve, change-over valve, hydraulic control one-way valve and pipeline etc. are to the hydraulic actuating cylinder fuel feeding, then hydraulic cylinder piston rod 1 moves up or down, when piston rod 1 upward movement, then jack-up sliding sleeve 5 and raising legs head 2 upward movements that are fixed together with sliding sleeve 5, because promoting rigging 3 is the pulleys that stride across raising legs head 2, one end is fixed on the base 7 and keeps relative motionless with metal can base plate 9, the other end then is fixed on the packing hanger ring 12, and the drive metal can is constructed with the bearing plate 13 that packing 11 also relies on and metal tank skin 10 is fixed, and metal tank skin 10 is mentioned upward movement.When enclosing the tank shell welding, finishes first lap tank shell and second, the change-over valve at operating hydraulically operated station 6, make hydraulic cylinder piston rod 1, sliding sleeve 5, raising legs head 2, lifting rigging 3 and packing 11 etc. fall back to initial position, finish first working cycle, prepare to enter second working cycle.Analogize in proper order, finish until final section tank shell assembly welding.
