Abstract
A kind of hydraulic pressure hollow cylinder head track device, belong to hoisting crane hydraulic pressure top rail machine mechanical field, architectural feature is that top is shaped with the trough-shaped base turning limit and is fixed on below Gantry Crane, upper limit position switch is arranged on Gantry Crane lower surface, lower position switch is arranged on trough-shaped base upper surface, hydraulic pressure hollow cylinder top is connected with trough-shaped base lower surface, be set with the step push rod of belleville spring group through hydraulic pressure hollow cylinder heart portion and trough-shaped base centre hole, its lower end flanges is fixed on hydraulic pressure hollow cylinder piston, the setting nut that is equipped with of its upper end and regulate pad and upper, lower position switch is mounted opposite, slipper is connected with step push rod lower end, advantage is the friction force that the hydraulic coupling that simultaneously provided by hydraulic pressure hollow cylinder and belleville spring group and pressing force of the spring can increase between head track device and track, realize hydraulic pressure and spring pressure double insurance capability of anti-wind, when belleville spring group lost efficacy, still realize protection effect by hydraulic coupling.
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 of the locomotive crane at outside work, as handling bridge, transfer crane, bucket-wheel stacker reclaimer, span winch etc. all will install the windproof antiskid head track device preventing from being 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 the action of the spring, promotes slipper pressure in orbit, plays AsA-GSH cycle; When hoisting crane operates, jacking block lifts by hydraulic efficiency gear, 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 the wind loading rating having influence on top rail machine, simultaneously during spring fault, can lose capability of anti-wind.
Summary of the invention
The object of this invention is to provide a kind of hydraulic pressure hollow cylinder head track device, effectively can overcome the shortcoming that prior art exists.
The present invention realizes like this, as shown in Figure 1, its architectural feature is that top is shaped with the trough-shaped base 3 turning limit and is fixedly connected on below Gantry Crane 2 by one group of screw, hydraulic actuating cylinder urceolus 4 top to be fixedly connected on below trough-shaped base 3 on center by one group of screw, the upper cylinder cover 14 being 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 bottom by one group of screw, the top of step push rod 10 is through the centre hole bottom trough-shaped base 3, its top is provided with setting nut 16 and adjusting disk 17, belleville spring group 12 is sleeved on the middle part of step push rod 10 and is arranged in hydraulic actuating cylinder inner core 6, upper limit position switch 1 is arranged on below Gantry Crane 2, the lower end of upper limit position switch 1 is corresponding with the upper end of step push rod 10, lower position switch 15 is arranged on the groove face of trough-shaped base 3, and be positioned at below setting nut 16 and adjusting disk 17, 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 provided by the hydraulic pressure hollow cylinder in 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 ensure 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 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 trough-shaped base birds-eye view;
In figure: 1-upper limit position switch, 2-Gantry Crane, 3-trough-shaped base, 301-first screw hole, 302-second 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-adjusting disk.
Detailed description of the invention
As shown in Figure 1, 2, hoisting crane is when needs are shut down, and head track device is under belleville spring group 12 acts on, promoting slipper 9 is pressed on track 8, if insufficient pressure, when cannot touch lower position switch 15, start the oil pump be communicated with hydraulic actuating cylinder, hydraulic oil is from the oil-feed of upper hydraulic fluid port 13, promote piston 5, step push rod 10 is moved down, makes slipper 9 compress track 8, realize spring pressure and hydraulic pressure double cropping for track 8, play AsA-GSH cycle; When hoisting crane operates, from the oil-feed of lower hydraulic fluid port 11, lift piston 5, drive slipper 9 to lift, leave rail level, make hoisting crane normal operation.
