Description
Technical field
The invention belongs to hydraulic pressure and raise mechanical field, be specifically related to a kind of change stroke hydraulic push lifting device.
Background technology
Hydraulic pressure push lifting device is used widely in multiple industry engineering practice, at present, mostly the hydraulic pressure push lifting device of use is hydraulic jack, and the shortcoming that this machinery in use exists is that range is fixed, field of application is restricted, and significantly limit the commonality of use.
Summary of the invention
The object of this invention is to provide a kind of hydraulic pressure push lifting device becoming stroke, effectively can overcome the shortcoming that prior art exists.
The present invention realizes like this, as shown in Figure 1, its architectural feature is, be connected with sleeve 4 by the first tie bolt 3 on the top of hydraulic actuating cylinder 1, the top of sleeve 4 is connected with the tapped bore 708 of control mechanism 7 by the second tie bolt 9, sleeve 4 wall is provided with permanent magnet 6 from top to bottom, under raise block 5, in raise block 5 ＇, on raise block 5 ＇ ＇ structure be middle part be cone, top is Mohs cone, bottom is the cylinder that its center is shaped with mohs tapered bore, the bottom of mohs tapered bore is shaped with removal hole, in raise block 5 ＇ by its top Mohs cone and bottom mohs tapered bore respectively with on raise block 5 ＇ ＇, under raise block 5 and connect, on raise block 5 ＇ ＇ bottom and be placed on above the loading arm 707 of control mechanism 7, its top is connected with back-up block 8 by Morse cone, the structure of control mechanism 7 is as Fig. 2, shown in 3, take up dish 701 and be shaped with centre hole, and be shaped with horizontal hole respectively all around what take up dish 701 circumference, in each hole, the inside is the loading arm 707 of horizontal surface above being equipped with, outermost is equipped with magnet coil 703, magnet coil 703 be fixed on by back-up ring 704 take up dish 701 periphery on, in magnet coil 703, kink has "T"-shaped push rod 702, on push rod 702, kink has Compress Spring 705, push rod 702 top is connected by nut 706 with loading arm 707 end, push rod 702 end is equipped with setting nut 709, raise under placing in sleeve 4 by sending block mouth 10 block 5 realize become stroke raise, under raise block 5, in raise block 5 ＇, above raise between block 5 ＇ ＇ and adopt Morse cone to connect.
Advantage of the present invention and good effect are:
When the stroke out of reach demand of hydraulic actuating cylinder, block can be raised by the loading of this mechanical flexibility, increase stroke.When the size of environment for use restriction hydraulic actuating cylinder, because this organization volume is little, and stroke is large, can meet and raise needs.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present invention;
Fig. 2 is control mechanism cutaway view in the present invention;
Fig. 3 is the schematic top plan view of Fig. 2;
Fig. 4 is magnet coil, push rod is connected enlarged drawing with loading arm;
In figure: 1-hydraulic actuating cylinder, 2-piston rod, 3-first tie bolt, 4-sleeve, raise block under 5-, 5 ＇-in raise block, 5 ＇ ＇-above raise block, 6-permanent magnet, 7-control mechanism, 701-takes up dish, 702-push rod, 703-magnet coil, 704-back-up ring, 705-Compress Spring, 706-coupling nut, 707-loading arm, 708-tapped bore, 709-setting nut, 8-back-up block, 9-second tie bolt, 10-send block mouth, and 11,12-oil inlet and outlet.
Detailed description of the invention
As Fig. 1, shown in 2, hydraulic pressure push lifting device of the present invention can be placed on by initial position as required to be needed on the position that raises, by Morse cone assembling back-up block 8, on raise block 5 ＇ ＇ and in raise block 5 ＇, and by manipulation electromagnet, by on raise block 5 ＇ ＇ and be placed on control mechanism 7 all around on loading arm, by under raise block 5 and load in sleeve 4 by sending block mouth 10, stayed by gluing permanent magnet 6 magnetic in blind hole that sleeve 4 wall is offered and raise block 5, be contained in piston rod 2 top, manipulation hydraulic actuating cylinder 1 raises block 5 under piston rod 2 is promoted and rises, raise block 5 under piston rod 2 top to move along the guide direction that permanent magnet 6 is formed and boost, by in the taper hole that all around loading arm is formed to control mechanism 7, by manipulation electromagnet, loading arm all around is outwards shunk, under raise block 5, in raise block 5 ＇ and set up Morse cone frictional connection, in raise the upside of block 5 ＇ to all around loading arm, again by manipulation electromagnet, loading arm all around is inwardly shunk, again piston rod 2 is regained, if the height raised raises the integral multiple of block 5 length under not being time, can manipulate hydraulic actuating cylinder 1 makes piston rod 2 regulate.If raise stroke not enough time, again lay second and raise block and boost, by that analogy, stroke is extended to can be needed.
