Description
Technical Field
The utility model relates to the field of mechanical equipment, concretely relates to hydro-cylinder bottom of a jar.
Background
The grab bucket is a special tool for grabbing dry and scattered goods by a crane. The driving mode can be divided into two categories of hydraulic grab bucket and mechanical grab bucket. The hydraulic grab bucket is provided with an opening and closing structure, is generally driven by a hydraulic oil cylinder, and is also called as a hydraulic claw consisting of a plurality of jaw plates. The hydraulic grab bucket is widely applied to hydraulic special equipment, such as a hydraulic excavator, a hydraulic lifting tower and the like. The hydraulic grab bucket is composed of hydraulic cylinder, bucket (jaw plate), connecting upright post, bucket ear plate, bucket ear cover, bucket tooth and tooth holder. Among them, the hydraulic cylinder is the most critical driving part. The hydraulic oil cylinder is generally hinged on the connecting upright post through the cylinder bottom, and the hydraulic oil pipe is connected with the cylinder bottom to control the hydraulic oil cylinder. In the prior art, the bottom of the oil cylinder generally comprises a sealing flange and a hinged lug, the hinged lug is fixed at the rear end of the sealing flange, a hydraulic oil cavity is formed in the front end of the sealing flange, an oil inlet hole is formed in the side face of the sealing flange, the oil inlet hole is communicated with the hydraulic oil cavity, and a hydraulic oil pipe is connected into the oil inlet hole.
However, the grab bucket is used for loading and unloading various goods, and various environments are complicated. Some goods are messy and are extremely sharp, such as goods in a waste recycling station, a garbage dump, and the like. When the grab bucket is operated, the goods can contact the hydraulic oil pipe, damage is caused to the goods, and safety accidents are caused.
Therefore, how to improve the cylinder bottom of the existing grab bucket cylinder to overcome the above problems is a problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple structure, safe and reliable, processing convenient grab bucket hydro-cylinder bottom.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a cylinder bottom of a grab bucket oil cylinder comprises a sealing flange and a hinge lug ring, wherein the hinge lug ring is fixedly arranged at the rear end of the sealing flange, a hydraulic oil cavity is formed in the front end of the sealing flange, and a hinge hole is formed in the hinge lug ring; the method is characterized in that:
the hinged earring comprises an outer ear body and an inner ear body, a through cavity is formed between the outer ear body and the inner ear body, a through hole is formed in the top end of the outer ear body, and the hinged hole is formed in the inner ear body;
an oil inlet hole is formed in the rear end of the sealing flange, a drainage tube is connected in the oil inlet hole and located in the through cavity, and the drainage tube penetrates through the through hole and is suitable for being connected with a hydraulic oil pipe.
As an improvement, a plurality of reinforcing blocks are arranged between the outer ear body and the inner ear body and are arranged at intervals, the reinforcing blocks are respectively arranged on two sides of the through cavity, and the drainage tube is positioned between the reinforcing blocks on two sides. The arrangement of the reinforcing block enables the outer ear body and the inner ear body to be integrated on one hand, and the strength of the hinged earring is ensured; on the other hand, the drainage tube can be protected, and the drainage tube can also be fixed on the reinforcing block through the cable tie.
Preferably, the oil inlet is L-shaped, and the oil inlet is communicated with the hydraulic oil cavity from the side surface. The hinged earrings are bypassed in the oil inlet holes of the structure, so that holes are prevented from being formed in the hinged earrings, and the strength of the hinged earrings is guaranteed.
Compared with the prior art, the utility model has the advantages of: the bottom of the oil cylinder of the conventional structure on the grab bucket is fed with oil from the side surface of the sealing flange, and the hydraulic oil pipe of the structure is exposed on the side surface, is low in position, is easy to scrape by goods and has potential safety hazards. Consequently, this side improves this, makes hydraulic pressure oil pipe connect on articulated earring top, makes to be in the high-order, keeps away from the goods, avoids the goods to cause the damage to hydraulic pressure oil pipe.
It should be noted that, an oil inlet is directly formed at the top end of the hinged earring and communicated to the hydraulic oil cavity, although the beneficial effect of the scheme can also be achieved, the oil inlet formed with the structure has the advantages of high forming difficulty, high cost and low economic benefit. Therefore, this scheme has adopted the articulated earrings of the components of a whole that can function independently structure that comprises the outer ear body, the inner ear body and boss to adopted the drainage tube to connect as the oil feed passageway, made it when guaranteeing intensity, can be convenient process, can realize above-mentioned beneficial effect, controlled manufacturing cost again.
It is worth mentioning that the processing sequence of the scheme is as follows: (1) processing and forming a sealing flange, an outer ear body, an inner ear body and a reinforcing block, and cutting a drainage tube with a proper length; (2) welding and fixing the inner ear body on the sealing flange; (3) welding and fixing the external ear body on the sealing flange; (4) installing a drainage tube; (5) the reinforcing block is welded between the outer ear body and the inner ear body. If necessary, the drainage tube can be fixed on the reinforcing block by a cable tie.
