Abstract
The utility model relates to a lifting tool for disassembly and assembly of a hydraulic oil cylinder of a press. The lifting tool can facilitate the assembly and the disassembly of hydraulic oil cylinders of large-size presses, especially portal presses, and equipment can be conveniently disassembled, assembled and protected. The lifting tool comprises a lifting lug. The lifting lug is welded on a cylinder body connecting disc. Bolt holes are arranged on the cylinder body connecting disc. A piston fixing lead screw is welded in the center of the lower end surface of the cylinder body connecting disc. By connecting the lifting tool with a cylinder body and a piston of the hydraulic oil cylinder, the disassembly and the assembly are facilitated. The lifting tool has the advantages that the structure is simple, the lifting tool is convenient to use, and the disassembly and the assembly of the hydraulic oil cylinders of the large-size presses are greatly facilitated; people are not required to climb up and down a rack in order to lift the hydraulic oil cylinder, and the lifting operation and the installation of the oil cylinder are simplified; and the hydraulic oil cylinder is protected, a crane is only required during disassembly and assembly, the equipment used for disassembly and assembly is reduced, the safety of disassembly and assembly is improved and the labor intensity of workers is reduced.
Description
Technical field
The utility model belongs to the dismounting aid of forcing press, and particularly forcing press hydraulic jack dismounting suspender makes things convenient for large pressing machine, is particularly useful for the installation and removal of gate-type forcing press hydraulic jack, easy disassembly, protection equipment.
Background technology
The total height of large-sized gantry hydropress frame generally is a 5-6 rice, and its hydraulic jack is installed in the crossbeam of gate-type forcing press.Because of its weight is big, generally more than 10T, piston rod is longer, and generally at 2-3 rice, work brings very big difficulty to field-strip.Method in the past is in the maintenance unloading process, to be screwed into two suspension ring symmetries in the screw of cylinder body upper end, and this screw is towards liquid valve installation screw, with two suspension ring of steel wire penetrating, hangs the cylinder body of hydraulic jack through crane, falls earthward.Maintenance finishes, and when frame lower is installed toward crossbeam, needs hydraulic jack from the frame bottom oil cylinder to install the hole and pass steel wire rope, hangs wire line hitch in the suspension hook of crane in the frame top position.Along with the crane hydraulic jack of slinging, because the piston rod in the cylinder body is not fixed, can marks along with the rise of hydraulic jack and fall, make the total length of hydraulic jack surpass the total height of frame, cause hydraulic jack can't be installed in the installing hole on the frame.Need this moment to cooperate repeatedly moving of crane with the front fork of hydraulic pressure fork truck, the bottom that piston rod is chosen on the top makes the installing hole of the slow vertical centering of hydraulic jack on frame.This method wastes time and energy; The flexible distortion of reason that angle tilted when symmetry was screwed into two interior bolt suspension ring of cylinder body upper end screw because of hydraulic jack own wt and lifting; The adjustment lifting angle of repeatedly rising and falling during lifting has the danger that fractures, and causes suspension ring dismounting difficulty.Owing to do not have auxiliary dismounting of special hanger and installation, bring great difficulty for the maintenance of gate-type forcing press, working strength of workers is big, and the poor stability of operation, hydraulic jack, piston rod surface are vulnerable to damage.
Summary of the invention
The purpose of the utility model provides forcing press hydraulic jack dismounting suspender, makes things convenient for the dismounting and the installation of hydraulic jack, and protection equipment reduces working strength of workers, improves the security of work.
The technical scheme of the utility model is: forcing press hydraulic jack dismounting suspender comprises hanger, and hanger is welded on the cylinder body terminal pad, on the cylinder body terminal pad, is provided with bolt hole, and its center, lower surface welding piston is leading screw fixedly.The utility model is connected for convenience detach and installation with piston with the cylinder body of hydraulic jack.
Compared with prior art, the beneficial effect of the utility model is: the utility model is simple in structure, and is easy to use, is very easy to the dismounting and the installation of large pressing machine hydraulic jack.Cylinder body terminal pad through the utility model and piston be leading screw fixedly; The cylinder body and the piston of hydraulic jack are linked together; The piston rod of hydraulic jack is no longer marked along with moving of cylinder body; Can shift out from the frame below easily and pack into, no longer need the workman, simplified the installment work of lifting operation and oil cylinder for the lifting hydraulic jack climbs down on frame is swashed.When having protected hydraulic jack, only need crane to cooperate dismounting, also reduced the equipment of employing of disassemble and assemble work, the security that has improved disassemble and assemble work has reduced working strength of workers.
Description of drawings
Fig. 1 is the front view of the utility model structural representation.
Fig. 2 is the application sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to Fig. 1; Forcing press hydraulic jack dismounting suspender comprises hanger 1; Hanger 1 is welded on the cylinder body terminal pad 2, on cylinder body terminal pad 2, is provided with bolt hole, its center, lower surface welding piston is leading screw 3 fixedly.Bolt hole on the cylinder body terminal pad 2 and cylinder body upper surface be towards the corresponding setting of liquid valve installing hole, four bolts hole of operated by rotary motion, stressed evenly.
Referring to Fig. 2, during the dismounting hydraulic jack, earlier piston rod 5 is moved to the appropriate location in cylinder body 4, fixedly leading screw 3 rotations are stubborn solid in the craft thread hole of top land the piston of this suspender bottom.Four bolts hole that dash on liquid valve installing hole and the cylinder body terminal pad 2 on cylinder body 4 upper surfaces are aligned.Be fastened together the cylinder body 4 of the utility model and hydraulic jack with bolt.Steel wire rope is penetrated in the hanger 1, and the piston rod in the cylinder body 45 just can not glide in hoisting process like this.Cylinder body terminal pad 2 is because of being fastenedly connected with four bolts and cylinder body 4, and four bolts are evenly stressed, and dismounting easily.The front fork that also need not the hydraulic pressure fork truck when hydraulic jack is installed cooperates the crane top to choose piston rod, repeatedly moves hydraulic jack, the phenomenon of bolt distortion, dismounting difficulty can not occur.
When hydraulic jack is installed, earlier the cylinder body 4 of the utility model and hydraulic jack and the piston at piston rod 5 tops are connected, move to the below of gate-type hydropress frame,, be connected with hanger 1 with putting down the hydraulic jack installing hole of steel wire rope from the gate-type hydropress frame.The crane lifting winches to hydraulic jack the below of housiung separator; Winch in the hydraulic jack installing hole after aligning with the hydraulic jack installing hole; Make that disc flange circular hole and crossbeam below oil cylinder screwed hole aligns on the hydraulic jack, the bolted of screwing on gets final product, and the utility model is unloaded treat to use next time again.
