Grabbing device of ream grab

Abstract

The invention discloses a grabbing device of a ream grab. The grabbing device comprises a first grabbing arm, a second grabbing arm, connection plates, slide grooves, fixing rods, hydraulic rods, antiskid buckles, telescopic columns, racks, electric motors, drill bits, lifting rods, damping springs, limiting holes, reinforcing plates and fastening bolts. The grabbing device has the beneficial effects that by connecting the two sets of hydraulic rods between the first grabbing arm and the second grabbing arm, the distance between the first grabbing arm and the second grabbing arm can be changed according to the practical work requirement. The grabbing arms can grab objects of different sizes, each damping spring is installed on one side of the corresponding hydraulic rod, vibration between the grabbing arms is buffered, and the grabbing device can be more stable during work. The multiple sets of antiskid buckles are welded to one side of the first grabbing arm and one side of the second grabbing arm, and therefore the friction force between the grabbing arms and the objects can be increased, and the objects are not likely to fall. By means of the device, the distance between the grabbing arms can be regulated according to the sizes of the objects, meanwhile, object grabbing is more stable, and the service life of the racks is prolonged.

Description

technical field [0001] The invention relates to a grabbing device, in particular to a grabbing device for a soil grabber, which belongs to the application field of engineering machinery. Background technique [0002] With the continuous development of construction machinery, in order to speed up the construction progress of the project, various construction machinery have appeared on the construction site. A soil grabber is a construction machine that can quickly grab objects. The engine and manipulator drive the front grabbing device to grab objects and move them to other places. [0003] But existing grasping grasping device still has some deficiencies in use. When the existing grasping device is in use, it cannot change its own size according to the size of the object, and it often occurs that the grasping area of ​​the grasping device is not enough to grasp large objects. During the grasping process, due to insufficient grasping force, the object is easy to fall during...

Problems solved by technology

[0003] But there are still some deficiencies in the existing grasping and grasping device in use

When the existing grabbing device is in use, it cannot change its size according to the size of the object. Often, the grabbing area of ​​the grabbing device is not enough to grab large objects

During the grasping process, due to insufficient grasping force, the object is easy to fall during the grasping process

When encountering hard materials, the rack at the front will be severely worn and the service life will be short
