Abstract
The utility model discloses a structure of a water leakage hole. The structure comprises a main oil cylinder gland, a dust ring installed on the main oil cylinder gland, a guide sleeve and a flange. The main oil cylinder gland, the guide sleeve and the flange are sequentially connected and fixed. The structure is characterized in that a water leakage hole is drilled in the main oil cylinder gland and communicated with through holes on the guide sleeve and the flange. By adopting the structure of the water leakage hole, the water is prevented from entering an inner hole of an oil cylinder, and the emulsification of hydraulic oil and oil cylinder failure are avoided.
Description
Technical field
The utility model relates to the constructional engineering machinery technical field, is specifically related to the water-leaking hole structure of concrete pumping oil cylinder.
Background technique
Available coagulation soil pumping oil cylinder waterproof construction, constitute by seal element, when the concrete pumping oil cylinder carries out work, because the wearing and tearing of seal element and piston rod are done round band water conservancy project and are done, cause water to enter cylinder bore, cause hydraulic oil emulsification, oil cylinder breaks down, shorten working life, harm such as cost of production raising.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of anti-sealing to enter cylinder bore, avoid the water-leaking hole structure of the concrete pumping oil cylinder of hydraulic oil emulsification and oil cylinder fault.
The technical solution adopted in the utility model is: this water-leaking hole structure, comprise the master cylinder gland, be installed in dust ring, guide sleeve and flange on the master cylinder gland, master cylinder gland, guide sleeve, flange are connected and fixed successively, feature of the present utility model is: be drilled with water-leaking hole on the master cylinder gland, water-leaking hole is connected with hole on guide sleeve and the flange.
In the technique scheme, rod seal is installed also on the master cylinder gland, the water-leaking hole that is drilled with on the master cylinder gland is between dust ring and rod seal.
In the technique scheme, the connection hole between guide sleeve and the master cylinder gland is equipped with the O RunddichtringO.
The utility model adopts increases the water-leaking hole structure, form the twice waterproof mechanism with original dust ring seal element, when oil cylinder is worked, do the motion of round band water by piston rod, the low amounts of water that first road sealing of process dust ring enters is discharged by water-leaking hole, anti-sealing enters cylinder bore, avoids hydraulic oil emulsification, causes the oil cylinder fault.The utility model is not only simple in structure, and loading and unloading, uses also conveniently, has saved user cost greatly.
