Abstract
The invention discloses a hydraulic hollow cylinder track jacking device which belongs to the field of crane hydraulic track jacking machinery. The device is structurally characterized in that a tank-shaped base with turned sides at the upper part is fixed below a crane rack; an upper limiting switch is arranged on the lower end surface of the crane rack; a lower limiting switch is arranged on the upper end surface of the tank-shaped base; the top end of a hydraulic hollow cylinder is connected with the lower end surface of the tank-shaped base; a stair-shaped jacking rod sleeved with a butterfly spring group penetrates through the central part of the hydraulic hollow cylinder and a central hole in the tank-shaped base; a flange at the lower end of the jacking rod is fixed on the piston of the hydraulic hollow cylinder; an adjusting screw nut and an adjusting pad arranged at the upper end of the jacking rod are arranged opposite to the upper and lower limiting switches; a brake block is connected with the lower end of the stair-shaped jacking rod. The device has the advantages that the friction between the track jacking device and a track is increased through hydraulic force and spring compression force simultaneously provided by the hydraulic hollow cylinder and the butterfly spring, a windproof capability with both hydraulic pressure and spring pressure is achieved, and when the butterfly spring group is invalid, the windproof effect can be still achieved through the hydraulic force.
Description
Technical field
The invention belongs to hoisting crane hydraulic pressure top rail machine mechanical field, be specifically related to a kind of hydraulic pressure hollow cylinder head track device.
Background technology
Hydraulic pressure head track device is the major part at the locomotive crane of outside work, as handling bridge, transfer crane, bucket-wheel stacker reclaimer, span winch etc., all will install and prevent the windproof antiskid head track device that blown away by strong wind.At present, mostly the hydraulic pressure head track device of use is single acting oil cylinder, and its principle of work is: hoisting crane is when power-off, and top rail machine, under action of the spring, promotes slipper and presses in orbit, plays antiskid effect; When hoisting crane operates, hydraulic efficiency gear lifts jacking block, leaves rail level, makes hoisting crane normal operation.The shortcoming that this machinery in use exists is that the wave degree of crane track can affect it to the thrust of track and then have influence on the wind loading rating of top rail machine, during spring fault, can lose capability of anti-wind simultaneously.
Summary of the invention
The object of the invention is to provide a kind of hydraulic pressure hollow cylinder head track device, can effectively overcome the shortcoming that prior art exists.
The present invention seeks to realize like this, as shown in Figure 1, its architectural feature be top be shaped with the flute profile base 3 that turns limit by one group of screw be fixedly connected on Gantry Crane 2 below, hydraulic actuating cylinder urceolus 4 tops are fixedly connected on the center below of flute profile base 3 by one group of screw, the upper cylinder cover 14 that is shaped with centre hole is connected with hydraulic actuating cylinder urceolus 4 by outside thread, the hydraulic actuating cylinder inner core 6 that upper end is shaped with flange is arranged on hydraulic actuating cylinder urceolus 4 inside, the piston 5 that upper end is shaped with flange is sleeved in the annular chamber between hydraulic actuating cylinder inner core 6 and hydraulic actuating cylinder urceolus 4, lower cylinder cap 7 is fixedly connected on the lower surface of hydraulic actuating cylinder urceolus 4 by one group of screw, the step push rod 10 that bottom is shaped with flange is sleeved in hydraulic actuating cylinder inner core 6, its bottom flange is fixedly connected with piston 5 bottoms by one group of screw, the top of step push rod 10 is through the centre hole of flute profile base 3 bottoms, its top is provided with setting nut 16 and regulates pad 17, the middle part that belleville spring group 12 is sleeved on step push rod 10 is arranged in hydraulic actuating cylinder inner core 6, it is right to top with step push rod 10 below that upper limit position switch 1 is arranged on Gantry Crane 2, lower position switch 15 is arranged on the groove face of flute profile base 3, and be positioned at setting nut 16 and regulate pad 17 below, slipper 9 is fixedly connected on below step push rod 10 by one group of screw, its center is corresponding with the line of centers of track 8.
Advantage of the present invention and good effect are:
When crane track 8 exists wave degree, the hydraulic coupling simultaneously providing by the hydraulic pressure hollow cylinder in the present invention and belleville spring group and pressing force of the spring increase the positive pressure between head track device and track, and then increasing friction force, can guarantee hoisting crane protection effect; Realize the windproof and windproof double insurance capability of anti-wind of spring pressure of hydraulic pressure, when belleville spring group lost efficacy, still can realize protection effect by hydraulic coupling.
Accompanying drawing explanation
Fig. 1 is structure cross-sectional schematic of the present invention;
Fig. 2 is step push rod schematic diagram;
Fig. 3 is flute profile base vertical view;
In figure: 1-upper limit position switch, 2-Gantry Crane, 3-flute profile base, 301-screw hole, 302-screw hole, 303-centre hole, 4-hydraulic actuating cylinder urceolus, 5-piston, 6-hydraulic actuating cylinder inner core, cylinder cap under 7-, 8-track, 9-slipper, 10-step push rod, hydraulic fluid port under 11-, 12-belleville spring group, the upper hydraulic fluid port of 13-, 14-upper cylinder cover, 15-lower position switch, 16-setting nut, 17-packing ring.
The specific embodiment
As shown in Figure 1, 2, when hoisting crane is shut down at needs, head track device is under 12 effects of belleville spring group, promoting slipper 9 is pressed on track 8, if insufficient pressure, in the time of cannot touching lower position switch 15, starts the oil pump being communicated with hydraulic actuating cylinder, hydraulic oil is from upper hydraulic fluid port 13 oil-feeds, promote piston 5, step push rod is moved down, make slipper 9 compress track 8, realize spring pressure and hydraulic pressure double cropping for track 8, play antiskid effect; When hoisting crane operates, from lower hydraulic fluid port 11 oil-feeds, lift piston 5, drive slipper 9 to lift, leave rail level, make hoisting crane normal operation.
