Problems solved by technology

The realization of the first synchronization technology requires the cross-connection of four oil cylinders, and requires an additional mechanical lock and unlocking mechanism to realize the locking and unlocking of the equipment, which takes up a lot of space, complex mechanical structure, and high cost
The realization of the second synchronization technology requires strict control of the sheet metal quality and processing tolerances of the mechanical parts, or adjusting and balancing the processing errors of the sheet metal parts through additional wire ropes and pulley blocks, and also requires additional mechanical locks and unlocking mechanisms to realize the equipment. Locking and unlocking, this technology requires high quality sheet metal processing, and the installation of equipment is complicated, which is likely to cause weak installation foundation, unequal rising speed of lifting arms on both sides, deformation of lifting arms, failure of self-locking device, hydraulic oil Road burst, leading to safety accident

Abstract

The invention discloses synchronous interlocking oil cylinders capable of being controlled in a crossed mode. A cylinder barrel (4) of each synchronous interlocking oil cylinder is connected with a rear cap (1) and a front cap (6), piston rods (5) are arranged in each cylinder barrel (4), and the piston rods (5) are connected with a valve block (7) through bolts; a one-way valve (23) is arranged on each valve block (7) in an inserted mode, a one-way throttle valve (8) is embedded in each valve block (7), and the one-way throttle valve (8) is limited by connecting a connector (9) with the one-way throttle valve (8) in a threaded mode; the interiors of the piston rods (5) are connected with a gland (2), a guiding rod (3) is arranged in each gland (2), and the guiding rod (3) is connected with the rear cap (1); four oil openings are formed in each valve block (7), and the four oil openings communicate with a rodless cavity (24), a plunger cavity (27) and a rod cavity (25) correspondingly through oil ways; and each rod cavity (25) and the corresponding plunger cavity (27) have equal action areas, and after the two oil cylinders are interconnected in a crossed mode, the absolute synchronization of the stretching out and the drawing back of the two oil cylinders is guaranteed. The synchronous interlocking oil cylinders have a compact structure, have a little impact on the locating distance and the travels of the oil cylinders, and have the advantages of being easy to operate, high in integration level, convenient to maintain, low in failure rate, and the like.

Description

Technical field: [0001] The invention relates to a synchronous interlock oil cylinder, in particular to a synchronous interlock oil cylinder with high integration, which can ensure absolute synchronization, can be cross-controlled, has pipeline explosion-proof function, and one-way throttling function. Background technique: [0002] There are usually two types of existing synchronous cylinder technologies: the first one is realized by two pairs of main and auxiliary cylinders (four in total) through equal-volume matching and cross-connection; the second is that the two cylinders are forced to synchronize by external mechanical structure constraints. The realization of the first synchronization technology requires the cross-connection of four oil cylinders, and requires an additional mechanical lock and unlocking mechanism to realize the locking and unlocking of the equipment, which takes up a lot of space, complex mechanical structure, and high cost. The realization of the s...
