Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] refer to Figure 2 to Figure 7 As shown, the telescoping control system of the outrigger cylinder according to the specific embodiment of the present invention, similar to the prior art, may include a plurality of outrigger cylinders 1 having a vertical outrigger cylinder 1a and a horizontal outrigger cylinder 1b. For clarity, the plurality of vertical outrigger cylinders 1a further includes a first vertical outrigger cylinder and a second vertical outrigger cylinder whose telescoping action start speed is slower than that of the first vertical outrigger cylinder. The rod cavity of each of the vertical outrigger cylinders 1a is respectively connected wit...

Abstract

The invention discloses a telescopic control system and method for support oil cylinders and mechanical equipment. The telescopic control system comprises the multiple vertical support oil cylinders. The vertical support oil cylinders (1a) comprise the first vertical support oil cylinders and the second vertical support oil cylinders with the telescopic action start speed lower than that of the first vertical support oil cylinders. Rod end chambers of the vertical support oil cylinders (1a) are connected with first work oil ways (2) respectively, non-rod chambers of the vertical support oil cylinders (1a) are connected with second work oil ways (3) respectively, and the first work oil ways (2) and the second work oil ways (3) of the vertical support oil cylinders (1a) are connected to a shared hydraulic oil supply element through corresponding reversing control valves. At least the first work oil ways (2) of the first vertical support oil cylinders or the second work oil ways (3) are provided with flow control valves, and the hydraulic oil conveying resistance of the first vertical support oil cylinders is adjusted through flow control over the flow control valves.

Description

technical field [0001] The invention relates to a hydraulic control system of mechanical equipment, in particular to a telescoping control system of an outrigger oil cylinder. On this basis, the present invention also relates to mechanical equipment with the expansion and contraction control system of the outrigger cylinder. In addition, the invention also relates to a stretching control method of an outrigger cylinder of an engineering machine. Background technique [0002] In order to ensure the safe and stable operation of some large-tonnage engineering vehicles (such as cranes, elevating fire trucks, etc.) Auxiliary support. [0003] Telescopic outriggers are usually powered by outrigger cylinders. Such as figure 1 Shown is a telescopic control system for outrigger cylinders, including a plurality of outrigger cylinders 1 with vertical outrigger cylinders 1a and horizontal outrigger cylinders 1b, each of the outrigger cylinders 1 is connected with a first working oil...
