Abstract
The utility model discloses an embedded type waste transfer station lifting hydraulic device, which comprises a hydraulic oil cylinder sleeve and a piston rod, wherein the outermost layer of the hydraulic oil cylinder sleeve us fixed on a lower flange, the top portion of the piston rod is fixed under an upper flange, the hydraulic oil cylinder sleeve is sleeved layer by layer from inside to outside with the piston rod as center, and cast iron casting pipes are respectively assembled on the piston rod and the upper end and the lower end of the oil cylinder sleeve on the inner layer. The oil cylinder sleeve is directly sleeved layer by layer from inside to outside with the piston rod as the center on the basis of keeping the advantages of existing device, thereby reducing the material consumption, and greatly lowering the manufacture cost, simultaneously the piston rod and the upper end and the lower end of the surface of the oil cylinder sleeve of the inner layer are respectively provided with cast iron sleeves, thereby further improving the guiding stability (small swinging), and the twisting degree is excellent.
Description
Technical field
The utility model relates to a kind of lifting hydraulic efficiency gear, particularly a kind of buried type garbage transhipment station lifting hydraulic efficiency gear.
Background technology
The buried type garbage transhipment station is that rubbish container is buried in underground, during transfer rubbish, rubbish container is risen, and moves to rubbish railway carriage top.The used hydraulic efficiency gear of buried type garbage transhipment station jacking system generally adopts plunger case and the lifting of pulley steel cable, and hoist cylinder is an one-level, and cylinder sleeve is a square tube, and its shortcoming is: 1, complex structure, energy consumption height, maintenance difficult; 2, because hoist cylinder is an one-level, in order to satisfy the rubbish container lifting travel, thereby the length of cylinder sleeve is longer relatively, so transhipment station must dig darker hole, could satisfy installation requirement; 2, because the guiding point of square cylinder sleeve is easy to wear, so stable winding degree is relatively poor.In order to overcome the deficiency of above-mentioned technology, the applicant has invented a kind of " buried type garbage transhipment station lifting hydraulic efficiency gear " (patent No. ZL200620034277.7), provide a kind of simple in structure, lowering energy-saving can shorten the buried type garbage transhipment station lifting hydraulic efficiency gear that cylinder sleeve length can satisfy the rubbish container lifting travel again.But, because this patent has three grades of hydraulic rams, consumption material is many, and manufacturing cost is higher, and this patent hydraulic efficiency gear is only to be respectively fitted with a cast iron sleeve pipe at the upper face of three grades of cylinder sleeves of nexine, and the poor stability during the cylinder sleeve slide relative (swing is big), winding degree are poor.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, for the user provides a kind of later-model buried type garbage transhipment station lifting hydraulic efficiency gear.
The technical solution of the utility model is achieved in that a kind of buried type garbage transhipment station lifting hydraulic efficiency gear, comprise hydraulic ram sleeve and piston rod, the outermost layer of described hydraulic ram sleeve is fixed on the lower flange, piston rod part is fixed on the upper flange below, it is characterized in that: described hydraulic ram sleeve is center, layer overlaps from inside to outside with the piston rod.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model, its hydraulic ram sleeve is made up of three grades of straight lifting mode cylinder sleeves.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model has oil inlet and outlet on the hydraulic ram sleeve.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model also is provided with deflation hole on the hydraulic ram sleeve.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model, the top of described cylinder sleeves at different levels is provided with dust ring, and dust ring one side on the outer oil cylinder sleeve abuts against the surface of its adjacent inner layer cylinder sleeve.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model, described cylinder sleeves at different levels inboard is provided with seal ring.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model, the two ends up and down on the cylinder sleeve surface of described piston rod and nexine are respectively fitted with the cast iron sleeve pipe.
A kind of buried type garbage transhipment station lifting hydraulic efficiency gear described in the utility model, described each nexine cylinder sleeve lower end is provided with spacing wire ring.
The utility model is with respect to the advantage of prior art: on the basis that keeps the existing apparatus advantage, connecing simply with the piston rod with the oil cylinder cover is the center, layer overlaps from inside to outside, and consumption material is few like this, and manufacturing cost reduces greatly; While is all assembled the cast iron sleeve pipe respectively at the two ends up and down on the cylinder sleeve surface of piston rod and nexine, has improved the guiding stability (swinging little) of lifting hydraulic efficiency gear so again, and winding degree is good.
