specific Embodiment approach

[0028] Such as figure 1 As shown, a kind of pincers, scissors and grasping multifunctional engineering attachment is composed of a grasping device (A) and a grasping device (B); figure 2 As shown, the grabbing device (B) includes a pincer-shear switching device (C). In the initial state, the grasping hydraulic cylinder (2) and the pincer hydraulic cylinder (5) are in an extended state, and the switching hydraulic cylinder (10) is in a contracted state. The attachment working mode is:

[0029] The grabbing hydraulic cylinder (2) and the pincers hydraulic cylinder (5) contract, the attachment moves to the suspended cement column, the grabbing hydraulic cylinder (2) extends, and the grabbing device (A) hugs the virtual of the cement column, Prevent the random swing of the cement column.

[0030] The pincer hydraulic cylinder (5) works to drive the pincer shear device to pinch the cement column. During the pincer crushing process, the base (3) can move along the direction of ...

Abstract

The invention discloses a multifunctional clamping, shearing and grasping integrated engineering accessory, and relates to the technical field of mechanical design and hydraulic control earthquake resistance and hazard mitigation. According to the multifunctional clamping, shearing and grasping integrated engineering accessory, only one pair of driving hydraulic cylinders are adopted to achieve the cement clamping and breaking function and the steel bar shearing function, a design mode of a wedge-shaped block is adopted, mechanical self-locking is formed, and great stability is achieved. The multifunctional clamping, shearing and grasping integrated engineering accessory has the functions of fixing, breaking, shearing and conveying, and therefore the holding and grasping operation of cement columns and the clamping and shearing operation of the cement columns are combined together, the integration degree is high, and the operation is easy; and under the condition that a base of a holding and grasping device does not move, the work mode that cement of the cement columns is clamped and broken firstly and then steel bars of the cement columns are sheared can be completed.

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 multi-functional engineering attachment integrated with pincers, shears and graspers. Background technique [0002] At present, the prevention of earthquakes has not made much progress, so post-earthquake rescue work is extremely important for saving people's lives. Nowadays, most of the people are concentrated in cities, and the core of urban buildings is reinforced concrete. Cement pillars are not easy to be broken during an earthquake, thus causing great difficulties in the post-earthquake rescue process. The current rescue process is to support and fix the cement column first, then use the cutting attachment, and finally use the handling attachment. Now it is necessary to design a multifunctional attachment that can combine fixing, cutting, and carrying to simplify. Contents of ...
