Detailed description of the invention
By reference to the accompanying drawings the utility model is made a detailed explanation.First state, these accompanying drawings are only used to basic structure of the present utility model is described in a schematic manner, therefore, and the formation that only display is relevant with the utility model.
Hydraulic lifting castor as shown in the figure, for shifting the casings such as electric refrigerator, lifting is steady and adjustable height is controlled, and a kind of hydraulic lifting caster device comprises castor 1, castor telescoping mechanism, supporting leg 2, base 3, baffle plate 4, castor mounting hole 5, hook 6, foot-operated piston 7, flowline 8, many logical oil-feed interfaces 22 and oil cylinder 21;
Four castors 1 are connected with four castor telescoping mechanisms respectively, four castor telescoping mechanisms are arranged on castor mounting hole 5 place of base 3 respectively, base 3 four jiaos has supporting leg 2, oil cylinder 21 and Duo Tong oil-feed interface 22 are positioned at immediately below base 3, oil cylinder 21 is provided with return opening 23, limit, base 3 top four is provided with baffle plate 4, and oil cylinder 21 is connected with foot-operated piston 7 by flowline 8, links up with 6 and is arranged on base 3 and for hanging foot-operated piston 7.
Described foot-operated piston 7 comprises shackle 9, rubber piston body 10, piston foot-operated 11, spring 12 under rubber protection, piston base 13, piston cylinder 14, in line check valve 15 and oil outlet one-way valve 16, piston base 13 is provided with the spring 12 under rubber protection and piston cylinder 14, piston cylinder 14 is arranged in the spring 12 under rubber protection, spring 12 upper end under rubber protection is provided with piston foot-operated 11, piston foot-operated 11 is provided with shackle 9, described shackle 9 hangs foot-operated piston 7 for coordinating hook 6, piston is ridden 11 and is connected with the rubber piston body 10 in piston cylinder 14 by piston rod, both sides, piston cylinder 14 bottom are respectively arranged with in line check valve A15 and oil outlet one-way valve 16.
Described castor telescoping mechanism comprises telescopic piston 17, telescopic piston cylinder body 18, in line check valve B19 and fuel-return valve 20, described telescopic piston 17 upper end is installed on the base 3 by castor mounting hole 5, telescopic piston 17 matches with telescopic piston cylinder body 18, telescopic piston cylinder body 18 is connected with castor 1, telescopic piston cylinder body 18 is provided with in line check valve B19 and fuel-return valve 20.
Described oil cylinder 21 is connected with in line check valve 15, oil outlet one-way valve 16 is connected with many logical oil-feed interfaces 22 by pipeline, many logical oil-feed interfaces 22 are connected with the in line check valve B19 of four castor telescoping mechanisms respectively by pipeline, and fuel-return valve 20 is connected with return opening 23 by pipeline.
When needs utilize castor transferring objects, first, the foot-operated piston 7 be suspended on hook 6 is taken off be placed on the ground, step on foot-operated, then unclamp, foot-operated recovery automatically under the spring 12 under rubber protection acts on, fluid enters piston by pipeline via unidirectional inlet valve A15 by oil cylinder; And then firmly step on piston, piston inner fluid is arrived by pipeline by unidirectional delivery valve 16, under the shunting action of many logical oil-feed interfaces 22, hydraulic oil liquid to enter above each castor in telescopic piston 17 by four pipelines by line check valve B19, telescopic piston cylinder body 18 inner fluid liquid level is made to increase, castor telescopic piston 17 is extended immediately, and castor starts to extend; Along with constantly trampling foot-operated piston 7, fluid in castor telescopic piston cylinder body 18 gets more and more, base extends with telescopic piston 17 and rises, and castor stretches out outside supporting leg, observes can stop trampling foot-operated piston 7 when stretching out highly suitable object is walked; After completing walking work, open fuel-return valve 20, fluid gets back to fuel tank by pipeline via return opening 23, and castor slowly shrinks again, by supporting leg supporting object.
Because the frequency of trampling foot-operated piston is higher, it is larger that pin steps on dynamics, and the speed that castor rises also can be larger, therefore controls castor easily by dynamics on control pin and frequency and extend speed; Extend to stop the continuation of castor because we can stop trampling foot-operated piston at any time, therefore castor rise height is controlled; And because hydraulic efficiency pressure system is at the equilibrium of pressure at four castor places, so system rises steadily.
