specific Embodiment approach

[0034] Such as figure 1 , Figure 6 , Figure 7 as well as Figure 12 , a multifunctional engineering attachment of a six-bar mechanism is composed of a six-link clamping device (A), a scissor separating device (B), a shearing device (C), and a locking device (D). Such as figure 1 As shown, the multifunctional attachment is in the working state of shearing and crushing. At this time, the positioning block (7) on the attachment bracket (3) is inserted into the positioning groove (6), the scissors separation device (B) is in the closed state, and the attachment bracket (3) and the attachment base (2 ) is relatively fixed. The six-link clamping device (A) is in the retracted state, and the swing hydraulic cylinder (19) is locked to keep the position of the clamping hand (15) to prevent it from interfering with the work of the hydraulic scissors (5). Drive the hydraulic cylinder (4) as the main power source to push the hydraulic scissors (5) to rotate, the hydraulic scissor ...

Abstract

A multifunctional engineering attachment of a six-bar mechanism, which includes a six-link clamping device, a scissor separating device, a shearing device, and a locking device. Among them, the swing hydraulic cylinder of the six-link clamping device realizes the movement and locking of the six-link rod group, and completes the push-out and retraction of the clamping hand. The scissors separation device can separate the attachment bracket to achieve multifunctional attachment. Grasp the horizontal size requirements of the work, the shearing device is to realize the cutting and crushing functions of the multi-functional attachment, and the locking device is to determine the movement position of the attachment bracket, and at the same time bear the reaction force generated by the multi-functional attachment. The whole device uses a hydraulic cylinder as a power device. The invention combines the three functions of shearing, crushing and clamping into one attachment, with novel structural design, reasonable driving mode, simple manufacturing process, and easy operation by personnel, and can well complete the crushing and moving of ruins and Improve the efficiency of economic construction.

Description

technical field [0001] The invention relates to the technical fields of mechanical design and hydraulic control for earthquake resistance and disaster reduction, and specifically belongs to a multifunctional engineering attachment of a six-bar mechanism. Background technique [0002] Earthquake disasters will cause direct and indirect damage and loss to national economic construction and people's life and property safety. Investing in more efficient post-earthquake disaster relief equipment is of great significance for saving tens of millions of lives. Combined with the current earthquake relief methods, it can be seen that hydraulic breakers and stone grabbers have played an important role in the post-earthquake disaster relief work, so realizing one machine with multiple functions has important practical significance for disaster relief or economic construction. At present, the structure adopted to realize multi-functional operation on the same rescue equipment is mostly ...
