Embodiment 1

[0045] Such as figure 1 ,2,3, A multi-functional engineering attachment is composed of a pincers and shears device A, a holding device B, and a separating and deforming device C. This genus has three kinds of motion states: shearing and crushing working state; holding and grasping working state; separation and deformation motion state.

[0046] Such as Figure 15 ,16. The attachment is in the state of separation and deformation. Before the separation and deformation movement, the drive hydraulic cylinder 4 needs to be locked, according to Figure 4 , it can be seen that the clamping device A is a component.

[0047] Then the pincers and shears device A, the separation connecting rod 8, the base 2 and the separation slider 11 form a double slider mechanism. Such as Figure 15, 16, the pincers and shears device A, the separating connecting rod 8, the holding connecting rod 6 and the holding claw 7 form an abcd four-bar mechanism. For ease of understanding, the base 2 is no...

Abstract

The invention provides a gripping-shearing-grabbing multi-functional engineering accessory applying a single-degree-of-freedom deformation mechanism. The gripping-shearing-grabbing multi-functional engineering accessory is of a symmetric structure, and comprises a gripping-shearing device, a holding-grabbing device and a separation-deformation device, and further comprises two hydraulic cylinders,a base, two separation bases, a driving hydraulic cylinder, hydraulic scissors, holding-grabbing connecting rods, holding-grabbing claws, separation connecting rods, base guiding rods, base sliding blocks, separation sliding blocks, first connecting rods, second connecting rods and separation sliding block rail grooves. The gripping-shearing-grabbing multi-functional engineering accessory provided by the invention has the beneficial effects that by utilization of a double-sliding-block mechanism, the relative movement between the holding-grabbing device and the gripping-shearing device is achieved; the switchover from the gripping-shearing device to holding-grabbing device is quickly completed; furthermore, the working requirements are met in all the working states; and no motion interference is caused.

Description

technical field [0001] The invention relates to the technical field of mechanical design and hydraulic control for earthquake resistance and disaster reduction, and specifically belongs to a multi-rod multifunctional engineering attachment. Background technique [0002] In recent years, earthquake disasters have occurred frequently, and national economic construction and people's life and property safety have been damaged and lost. Therefore, it is of great significance to use efficient post-earthquake disaster relief equipment to carry out demolition work in disaster areas. Referring to the current earthquake relief and rescue, it can be seen that hydraulic breakers and stone grabbers have played an important role in the demolition work of disaster relief, so the realization of one machine with multiple functions is extremely important for post-disaster demolition work or economic construction. significance. At present, the structure adopted to realize multi-functional op...
