Abstract

The utility model discloses a hydraulic grab which comprises a lifting rod, wherein, a support platform is connected at the lower end of the lifting rod, supporting columns are respectively arranged in the four corners of the support platform, the upper end of each supporting column is movably connected with the platform, the lower end of the supporting column is movably connected with a rear outer side surface of a grab claw, a supporting rod respectively extends out obliquely and upwards from the front upper corner of the side surface of the grab claw, the lower end of the supporting rod is fixedly connected with the garb claw, the upper ends of the two corresponding supporting rods are intersected through a central axle and movably connected, a piston rod is movably connected with the central axle, and a piston pipe is movably connected with the support platform. Two oil nozzles are installed on the outer wall of the piston pipe. Since the grab is hydraulically driven, the opening and the closing of the grab claw can be accurately and effectively ensured, and the powerful grabbing force is improved.

Description

Hydraulic grab

Affiliated technical field:

The utility model relates to a kind of loading-unload machine, is the folding of grabbing lobe with the telescopic drive of hydraulic piston, is mainly used in the grab bucket of grabbing loading and unloading of folder formula and mining clay.

The grab bucket that drives of the twisted rope of usefulness at present, the cost height, fault is many, and it is limited to grab the folder dynamics, so expense is higher, work efficiency is lower.

The content of utility model:

The purpose of this utility model provides a kind of grab bucket of grabbing lobe with hydraulic-driven, replace and reequip the twisted rope grab bucket of using on the present sandstone harbour, effectively guarantee grab bucket accurately effectively folding in use, make and grab bucket that in use fault is few, the work efficiency height, in use its twisted rope is easy to wear to have overcome the twisted rope grab bucket, and it is stuck easily to overstep the limit, and grabs phenomenons such as lobe opening and closing dynamics deficiency.

Its purpose can be by following scheme implementation: hydraulic grab of the present utility model comprises lifting arm, promote rod end and connect rack platform, four jiaos of rack platform respectively have a pillar, the upper end of pillar and this platform flexibly connect, the lower end of pillar flexibly connects with the back lateral surface of grabbing lobe, grab and go up the angle before the side of lobe each stretches out a pole obliquely, the lower end of pole with grab lobe and captive joint, intersect and flexible connection through center shaft the upper end of two corresponding poles.Piston rod and center shaft flexibly connect, and piston tube and rack platform flexibly connect, and two oil nozzles are arranged on the piston tube wall.Because grab bucket of the present utility model is hydraulic-driven, thereby can guarantee to grab the folding of lobe accurately and effectively, owing to be that piston rod produces operational forces when regaining, therefore can significantly reduce fault, improve work efficiency, reduced job costs.

Fig. 2: be the left view of hydraulic grab of the present utility model.

Specific embodiments:

Hydraulic grab of the present utility model comprises lifting arm (1), the lifting arm lower end connects rack platform (9), four jiaos of rack platform respectively have a pillar (2), the upper end of pillar and this platform flexibly connect, the lower end of pillar flexibly connects with the back lateral surface of grabbing lobe (6), grab and go up the angle before the side of lobe each stretches out a pole (5) obliquely, the lower end of pole with grab lobe and captive joint, the upper end of two corresponding poles intersects at center shaft (8) and flexibly connects, piston rod (4) flexibly connects with center shaft, piston tube (3) flexibly connects with rack platform, and the piston tube outer wall is installed two oil nozzles (7).When piston rod was flexible, then the driving of this pole was grabbed the lobe folding, thereby realized the loading and unloading to goods.

Claims

A kind of hydraulic grab, comprise lifting arm, the lifting arm lower end connects rack platform, and four jiaos of rack platform respectively have a pillar, and the upper end of pillar and this platform flexibly connect, the lower end of pillar flexibly connects with the back lateral surface of grabbing lobe, grab and go up the angle before the side of lobe each stretches out a pole obliquely, the lower end of pole with grab lobe and captive joint, intersect and flexible connection through center shaft the upper end of two corresponding poles, it is characterized by: piston rod and center shaft flexibly connect, and piston tube and rack platform flexibly connect.
