Definitions

  • the present invention concerns sequence controlled hydraulic cylinders according to the preamble to claim 1, which is generally known.
  • the telescope elements When operating for example telescopic crane arms using a piston-cylinder means such as hydraulic cylinders it is desirable that the telescope elements are extended or contracted in a specific order so that it is possible to reliably determine the strength and thereby the dimensions of the telescope elements used in the crane arm.
  • the plus sides of the cylinders are in many cases under pressure at the same time. This means that the part of the crane arm that is extended is the one with the least friction or resistance due to load.
  • the minus sides of all the cylinders are under pressure at the same time and all the cylinders can move inwards until a valve is closed.
  • the cylinders can contract even more through the compression of the oil due to the load or similar. This means that the crane arm must be dimensioned for its weakest part and that the actual length extension of the crane arm can deviate from the desired length.
  • the order in which the telescopic elements move and the position to which they are to move can be determined by electronic means or by hydraulic valves with pilot lines but this can entail high cost.
  • One object of the present invention is to achieve a means of alleviating or remedying these shortcomings.
  • This object of the invention is achieved by pressurising only the innermost cylinder during a plus stroke and only the outermost cylinder during a minus stroke and that each cylinder must reach its end position before the next cylinder is allowed to start its movement.
  • This invention in comparison to other conventional solutions also means that even if the cylinder movement stops immediately the passage of oil via a valve to the next cylinder is opened, the valve's opening area will be large and the oil can pass. This involves considerably smaller pressure losses and thereby less heating of the oil than in conventional solutions where the valve's opening area is wholly dependent on how much the cylinder has moved after the valve has started to open.
  • the invention entails the flow of oil taking place through pipes inside and between the cylinders without the use of hoses.
  • the hydraulic cylinder illustrated in the drawings comprises a cylinder barrel 1 with a cylinder bottom 2 arranged at one end and a sealed cylinder head 3 arranged at the other end with a reduced diameter to form a ring gap 4 between the said cylinder head 3 and a piston 5, and one shoulder 6 intended for a spring 7 and one shoulder 8 intended for a valve body 9.
  • a pressure medium such as hydraulic oil.
  • the piston unit 13 has an axial drilling 17 along its length and an axially displaceable valve body 9 designed as a ring-shaped sleeve surrounding the piston unit.
  • a spring 14 is arranged between the valve body 9 and the piston unit 13 and a spring 7 intended to act between the valve body 9 and the shoulder 6 in the cylinder head 3.
  • the valve body 9 has a groove 15, which together with a bevelled edge 16 on the piston unit 13 forms a seat seal 18, a plunger seal 19 and a ring chamber 20.
  • the piston rod 5 which exhibits a passage 22 extending along its length containing two pipes 23 and 24, one surrounding the other, extends from the piston unit 13 through the chamber 12:2. With the seals 18, 19 in open position, the chamber 12:2 communicates via the ring chamber 20 that is formed by the seals 18, 19 with the radial passages 25 and 26 in the piston unit 13. On the piston unit 13 coupling to the piston rod 5 is arranged a seal 27 intended to seal the ring gap 4 with the piston unit 13 in its extended position.
  • the tubular piston 5 passes through the sealed cylinder head 3 and forms together with the pipes 23, 24 located in the passage 22 inside the piston 5 two ring chambers 28 and 29.
  • One end of the smaller pipe 23 is connected to the coupling 10 of the next cylinder via a coupling 37 and a pipe and the other end to a chamber 12:2 via a drilling 17 extending through the piston unit 13 in the longitudinal direction of the piston rod 5.
  • a radial drilled passage 30 that communicates with a cavity 31 in the outlet 11 with the piston rod 5 in its extended position.
  • a non-return valve 33 that is mechanically acted on by an arm 34 on an adjacent cylinder. The non-return valve 33 is intended to communicate with both ring chambers 28, 29 and an outlet 35.
  • each piston rod head 32 exhibits and arm 34 to control the non-return valve 33 on the following cylinder and works as follows:
  • cylinder I For plus movement, oil is led into cylinder I, whereby it will always start first.
  • hydraulic oil is led under pressure from the oil tank (not shown) by means of a pump (not shown) via a pressure retaining valve (not shown) through the coupling 10 inside the chamber 12:2 between the piston unit 13 and the cylinder bottom 2.
  • the piston unit 13 with piston rod 5 and via the piston rod head 32 including the other cylinders is forced to the right as shown in figure 1 , whereby the return oil from the other cylinders II and III linked with pipes is pressed out of the chamber 12:1 via the ring gap 4 and through the coupling 11 back to the tank.
  • valve body 9 meets the cylinder head 3 shoulder 8.
  • the seal 18 opens when the pressure is sufficient for the oil to pass via the drilling 17 and be forced into the chamber 20, thereby the closing pressure difference P1-P2 ceases.
  • the spring 7 overcomes the force of the spring 14 and the valve body 9 moves in the opposite direction to the piston unit 13, whereby the plunger and seat seals 18 and 19 open fully. Seals 18 and 19 open fully even if the cylinder travel ceases immediately the valve body 9 makes contact with the cylinder 3 shoulder 8 due to the pressure difference P 1-P2 ceasing when the seat seal 18 opens plus the spring force of spring 7.
  • the outermost cylinder III which is a conventional dual-action cylinder, will always start even though the pressurised oil has first passed through the inner cylinders I and II.
  • the pressure oil is passed via coupling 11 in cylinder I, through passage 30 into the ring chamber 28 since the ring gap 4 is sealed by seal 27 and on through coupling 35 to cylinder II and in the same way to cylinder III.
  • the return oil is passed out through coupling 10 on cylinder III to coupling 37 on cylinder II, through the inner pipe 23 in piston rod 5 and via the open plunger and seat valves 18 and 19 to passage 25, into the chamber 12:2 and out through coupling 10 on cylinder II and in the same way through cylinder I back to the tank.
