Abstract
The utility model relates to a small-size power-driven hydraulic expansion device, which comprises an enclosure 1, two expansion links 2 and 3, two outer seal rings 5 and 6, two inner seal rings 4 and 7, two oil transportation holes 8 and 9, two gear pumps 10 and 11, a motor 12, a hydraulic box 14, two hydraulic cylinders 15 and 16 and an air hole 13, wherein the two outer seal rings 5 and 6 are respectively arranged on one end of the expansion link 2 and one end of the expansion link 3; ends of the two expansion links 2 and 3, which are provided with the two outer seal rings 5 and 6, are respectively inserted into the two hydraulic cylinders 15 and 16; the two inner seal rings 4 and 7 are respectively sleeved into other ends of the two expansion links 2 and 3 so as to be fixedly arranged on ports of the two hydraulic cylinders 15 and 16; the two gear pumps 10 and 11 are respectively fixedly arranged in the enclosure 1; the motor 12 simultaneously drives the two gear pumps 10 and 11 to rotate forwardly and inversely; hydraulic oil circulates back and forth between the two hydraulic cylinders 15 and 16 and the hydraulic box 14 by the two oil transportation holes 8 and 9; the two expansion links 2 and 3 do an expansion motion simultaneously; and the air hole 13 is formed above the hydraulic box 14 and used for supplementing or reducing gas in a space when the hydraulic oil in the hydraulic box 14 is increased or reduced.
Description
Technical field:
The utility model relates to a kind of hydraulic telescopic device, relates in particular to a kind of small-sized electric hydraulic telescopic device.
Background technique:
The people who is engaged in the machinery installation and makes knows; In the middle of a heavy mechanical equipment, the application of hydraulic equipment be suitable extensively; And in the middle of changing more frequent machinery in small mechanical equipment or job site, to use hydraulic equipment be not so appropriate just; Because traditional in the past hydraulic equipment all is to be made up of parts such as a few part parts, oil hydraulic cylinder, hydraulic oil container, hydraulic oil pipe and oil hydraulic pumps respectively; In small mechanical equipment, use in this way traditional in the past hydraulic equipment will increase undoubtedly machinery volume, let small mechanical equipment become not small-sized, use so traditional hydraulically extensible equipment is unfavorable for small mechanical equipment.
The model utility content:
The purpose of the utility model is in order to overcome existing technical deficiency a kind of small-sized electric hydraulic telescopic device to be provided.
Specific embodiments is:
The small-sized electric hydraulic telescopic device comprises casing, two flexible rods, two exterior seal rings, two inner seal rings, two oil transportation holes, two gear pumps, motor, hydraulic fluid tank, two oil hydraulic cylinders, pore, that end that two exterior seal rings are fixedly mounted on an end of two flexible rods respectively, will be separately installed with two flexible rods of two exterior seal rings again injects in two oil hydraulic cylinders respectively, then with two inner seal rings pack into respectively two flexible rod the other ends make its be fixedly installed in two hydraulic cylinder ports, two gear pumps be fixedly mounted on respectively in the casing, by motor drive simultaneously two gear pump forward or reverse, through two oil transportation holes with hydraulic oil between two oil hydraulic cylinders and hydraulic fluid tank cycles back and forth, make its two flexible rods do simultaneously fore and aft motion, pore above hydraulic fluid tank, be used for the additional usefulness of hydraulic oil increase and decrease time space gas increase and decrease in the hydraulic fluid tank.
Only need when using the utility model small-sized electric hydraulic telescopic device motor is logically gone up power supply, adjustment electrode direction, makes its motor counter-rotating or just changeed, just can obtain the working principle of hydraulically extensible; Make its small mechanical equipment also can use this small-sized electric hydraulic telescopic device, realized the function of real small-sized electric hydraulic telescopic device.
From the technological scheme of the utility model small-sized electric hydraulic telescopic device can find out, since the utility model small-sized electric hydraulic telescopic device hydraulic fluid tank and two oil hydraulic cylinders are combined together; Separate with hard-wired two exterior seal rings on two flexible rods; Two flexible rods are stretched, hydraulic fluid tank increases, two oil hydraulic cylinders just dwindle; Otherwise flexible rod contracts, two oil hydraulic cylinder increases, hydraulic fluid tanks just dwindle; The utility model small-sized electric hydraulic telescopic device makes full use of the flexible rod principle that the inner space changes when flexible, dwindles the volume of this equipment small-sized electric hydraulic telescopic device to greatest extent; And use two gear pumps of a motor drives, make hydraulic oil through the counter-rotating of two gear pumps or just changeing between two oil hydraulic cylinders and hydraulic fluid tank cycles back and forth, make its two flexible rods carry out fore and aft motion, reached the goal of the invention of real small-sized electric hydraulic telescopic device.
Description of drawings:
Fig. 1: each the unit construction schematic representation that is the utility model small-sized electric hydraulic telescopic device.
Embodiment:
Like Fig. 1: shown in: the small-sized electric hydraulic telescopic device comprises that casing 1, two 8,9, two gear pumps 10,11 in 4,7, two oil transportation holes of 5,6, two inner seal rings of 2,3, two exterior seal rings of flexible rod, motor 12, hydraulic fluid tank 14, two oil hydraulic cylinders 15,16,13, two exterior seal rings of pore 5,6 are fixedly mounted on an end of two flexible rods 2,3 respectively, that end that will be separately installed with two flexible rods 2,3 of two exterior seal rings 5,6 again injects in two oil hydraulic cylinders 15,15 respectively, then with two inner seal rings 4,7 pack into respectively two flexible rods, 2,3 the other ends make its be fixedly installed in 15,16 mouthfuls, two gear pumps 10,11 of two oil hydraulic cylinders be fixedly mounted on respectively in the casing 1, by motor 12 drive simultaneously two gear pumps, 10,11 forward or reverse, through two oil transportation holes 8,9 with hydraulic oil between two oil hydraulic cylinders 15,16 and hydraulic fluid tank 14 cycles back and forth, make its two flexible rods 2,3 do simultaneously fore and aft motion, pore 13 above hydraulic fluid tank 14, be used for hydraulic oil hydraulic fluid tank 14 in and increase and decrease time space gas and increase and decrease additional usefulness.
