Abstract
The invention discloses a stable-form hydraulic grab. The stable-form hydraulic grab comprises a lifting rod, wherein the lower end of the lifting rod is movably connected with two symmetrically arranged grabbing flaps; the lower ends of the two grabbing flaps can form a closed structure; two sides of the upper end of the lifting rod are respectively connected with the grabbing flaps through two hydraulic oil cylinders; each hydraulic oil cylinder comprises a cylinder body, a front cylinder cover, a rear cylinder cover, a piston and a piston rod; the front cylinder cover and the rear cylinder cover are respectively fixed at both ends of the cylinder body in a sealing manner; the piston is received in the cylinder body and can reciprocate in the cylinder body; the piston rod is fixed on the piston and a positioning hole is formed in the piston rod; the cylinder body is provided with a positioning lock matched with the positioning hole. The stable-form hydraulic grab is simple in structure and convenient to use, and a certain angle is formed between the grab and cargos. The stable-form hydraulic grab is beneficial for transportation of the cargos, the piston rod can be positioned by the positioning lock without displacement, the stability of the hydraulic oil cylinder is improved, and the safe use of two grab flips is ensured.
Description
Technical field
The present invention relates to a kind of stable type hydraulic grab.
Background technology
Grab bucket is the bucket that crawl silt and various bulk freight can open and close.It is the suspender that a kind of folding that mainly keeps left right two combination buckets or multiple jaws captured and drew off bulk material.Existing handling equipment can only be straight up and down crawl goods, just need first goods is just being put when the out-of-shape of goods or while being inverted and then transport with grab bucket, like this will waste of manpower, increase shipment and delivery cost.Therefore, be necessary existing handling equipment to improve, can allow grab bucket shape have a certain degree, be convenient to the transport of goods, save manpower.
The hydraulic ram of prior art can not self-locking, when its conducted oneself with dignity or external load long lasting effect under, piston rod can be subjected to displacement, thereby affects the working stability of this hydraulic ram, from but grab the crawl material that lobe can not be stable, even cause safety misadventure.
Summary of the invention
The invention provides a kind of stable type hydraulic grab.
The technical solution adopted in the present invention is to achieve the above object of the invention: a kind of stable type hydraulic grab, comprise lifting arm, the lower end of described lifting arm is connected with two symmetrically arranged lobes of grabbing, two lower ends of grabbing lobe can form closing structure, both sides, described lifting arm upper end respectively by two hydraulic rams with grab lobe and be connected;
Described hydraulic ram comprises cylinder body, front end housing, back cylinder cover, piston and piston rod; Wherein, described front end housing and back cylinder cover seal respectively the two ends that are fixed on cylinder body; Described piston be contained in cylinder body and can be in cylinder body crank motion; Described piston rod is fixed on piston, is provided with thereon a knock hole; Described cylinder body is provided with the positioning lock of an energy and knock hole cooperation.
Further, the lower end of described lifting arm is provided with the support being flexibly connected with it, and the both sides, lower end of support connect respectively two and grab lobe.
Further, described upper cover of piston rod is provided with an orienting sleeve; This orienting sleeve is fixed on back cylinder cover.
Further, described support lower end is provided with two symmetrical rotating shafts; Two grab lobe is rotationally connected by rotating shaft and support respectively.
Further, the lower end of described piston rod is connected to the upper center of grabbing lobe.
The invention has the beneficial effects as follows: simple in structure, easy to use, can allow shape between grab bucket and goods have a certain degree, be conducive to the transport of goods, and this piston rod location can not be subjected to displacement by the positioning lock arranging, improve the stability of this hydraulic ram, guaranteed that two grab the safe handling of lobe.
