Abstract

The utility model relates to a variable-stroke hydraulic push-up device and belongs to the technical field of hydraulic push-up. The top end of a hydraulic cylinder is connected with a sleeve, the top end of the sleeve is connected with a control mechanism, and permanent magnets are installed on the inner wall of the sleeve from top to bottom. According to the structure of each push-up block, the upper end of the push-up block is a Morse taper, the middle of the push-up block is a cone, and the lower portion of the push-up block is a cylinder with a Morse taper hole as a center hole. The push-up block is connected with an upper push-up block and a lower push-up block through the Morse cone on the upper portion and the Morse taper hole in the lower portion. According to the structure of the control mechanism, transverse holes are manufactured in the front, the rear, the left and the right of the circumference of the control mechanism respectively, a bearing disk of a center hole is manufactured, a load bearing arm is installed in the innermost position in each hole, an electromagnetic coil is installed in the outermost position in each hole, a T-shaped push rod is movably arranged in each electromagnetic coil in a sleeved mode, each push rod is movably sleeved with a compression spring, the top end of each push rod is connected with a nut at the tail end of the corresponding load bearing arm, and an adjusting nut is installed at the tail end of each push rod. When push-up is conducted, different numbers of push-up blocks are placed through a block feeding port in the sleeve, and then variable-stroke lifting is achieved. The variable-stroke hydraulic push-up device has the advantage that the push-up stroke can be effectively adjusted by placing different numbers of push-up blocks.

Description

Become stroke hydraulic push lifting device

Technical field

The utility model belongs to hydraulic pressure and raises mechanical field, is specifically related to a kind of stroke hydraulic push lifting device that becomes.

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 has limited greatly the commonality using.

Summary of the invention

The purpose of this utility model is to provide a kind of hydraulic pressure push lifting device that becomes stroke, can effectively overcome the shortcoming that prior art exists.

The utility model is to realize like this, as shown in Figure 1, its architectural feature is, top at hydraulic actuating cylinder 1 is connected with sleeve 4 by tie bolt 3, the top of sleeve 4 is connected with the tapped bore 708 of control mechanism 7 by tie bolt 9, on sleeve 4 walls, permanent magnet 6 is installed from top to bottom, under raise piece 5, in raise piece 5 ＇, on raise piece 5 ＇＇ structure be that middle part is cone, top is Morse cone body, Wei Qi center, bottom is shaped with the cylinder of mohs tapered bore, the bottom of mohs tapered bore is shaped with removal hole, in raise piece 5 ＇ by its top Mohs cone and bottom mohs tapered bore respectively with on raise piece 5 ＇＇, under raise piece 5 and connect, on raise piece 5 ＇＇ bottoms be placed on control mechanism 7 loading arm 707 above, 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 respectively horizontal hole all around at its circumference, in each hole, the loading arm 707 for horizontal surface is above equipped with in the inside, outermost is equipped with magnet coil 703, magnet coil 703 is fixed on by back-up ring 704 on the periphery that takes up dish 701, there is "T"-shaped push rod 702 at the interior kink of magnet coil 703, on push rod 702, kink has Compress Spring 705, push rod 702 tops are connected by nut 706 with loading arm 707 ends, push rod 702 ends are equipped with setting nut 709, realize and become strokes and raise by sending piece mouth 10 to raise piece 5 under the interior placement of sleeve 4, under raise piece 5, in raise piece 5 ＇, above raise between piece 5 ＇＇ and adopt Morse cone to connect.

Advantage of the present utility model and good effect are:

In the time of the stroke out of reach demand of hydraulic actuating cylinder, can load flexibly and raise piece by this mechanism, increase stroke.In the time that environment for use limits the size of hydraulic actuating cylinder, because this mechanism's volume is little, and stroke is large, can meet and raise needs.

Fig. 4 is that magnet coil, push rod are connected enlarged drawing with loading arm;

In figure: 1-hydraulic actuating cylinder, 2-piston rod, 3-tie bolt, 4-sleeve, under 5-, raise piece, 5 ＇-in raise piece, 5 ＇＇-above raise piece, 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-bolt, 10-send piece mouth, and 11,12-oil inlet and outlet.

Detailed description of the invention

As Fig. 1, shown in 2, initial position can be placed on the utility model hydraulic pressure push lifting device on the position that need to raise as required, assemble back-up block 8 by Morse cone, on raise piece 5 ＇＇ and in raise piece 5 ＇, and by manipulation electromagnet, by on raise piece 5 ＇＇ and be placed on control mechanism 7 all around on loading arm, under inciting somebody to action, raise piece 5 by sending piece mouth 10 to pack in sleeve 4, stay and raise piece 5 by permanent magnet 6 magnetic gluing in the blind hole of offering on sleeve 4 walls, be contained in piston rod 2 tops, manipulation hydraulic actuating cylinder 1 makes to raise piece 5 under piston rod 2 promotions and rises, under piston rod 2 tops, raising guide direction that piece 5 forms along permanent magnet 6 moves and boosts, to in control mechanism 7 by the taper hole that all around loading arm forms, by manipulation electromagnet, loading arm all around is outwards shunk, under raise piece 5, in raise piece 5 ＇ and set up Morse cone frictional connection, in raise piece 5 ＇ to the upside of loading arm all around, again by manipulation electromagnet, loading arm all around is inwardly shunk, again piston rod 2 is regained, if the height raising raises the integral multiple of piece 5 length under not being time, can manipulate hydraulic actuating cylinder 1 regulates piston rod 2.If raise stroke when not enough, again lay second and raise piece and boost, by that analogy, stroke is extended to can be needed.
