Abstract
The utility model discloses a full-hydraulic capstan, composed of a machine frame, an oil distributor, a hydraulic motor, a brake, a planetary speed reducer, a capstan drum, etc. The utility model improves the connecting mode of the capstan drum and an output shaft of a planetary frame, a supporting structure, the separated type structure of a capstan control valve, the hydraulic motor and the oil distributor, etc. The utility model has simple structure, small size, convenient assembly, low cost, steady and reliable brake and high transmission efficiency.
Description
The utility model relates to the hydraulic wireline winch device.
Hydraulic wireline winch is to be that power promotes weight or transfer or promoting with hydraulic pressure, transfer the braking in the process, weight is suspended in the air, at construction machinery industry or harbour, Ship's Cargo is loaded the place widespread usage, the customer requirements hydraulic wireline winch has steady failure-free work and higher driving efficiency is arranged, and it is simple in structure, and existing hydraulic wireline winch complex structure, huge, poor performance, consumptive material is many, the cost height, be in particular in following several respects: the pinion carrier output shaft of (1) planetary reduction gear was connected by castellated shaft or flat key axle with being connected generally of capstan drum, made, processing, assembling is all difficult; (2) other end of hydraulic wireline winch is by support shaft supports, and its supporting structure is complicated, needs bearing cap shim, oil sealing etc.; (3) oil distributor of the fluid control valve of hydraulic wireline winch and HM Hydraulic Motor is a packaging structure, has increased the pipeline connection, makes the increasing that takes up room, and cost improves, and has increased the unreliability of leakage of oil and pipeline rupture; (4) power of capstan drum is driven through the multistage planet retarder by high-speed hydraulic motor, causes many defectives such as transmission net effciency reduction.
The purpose of this utility model all provides a kind of brand new all-hydraulic winch in the many defectives that overcome prior art, with reach simple in structure, good rigidly, volume is little, consumptive material is few, low cost of manufacture, purpose that driving efficiency is high.
According to above-mentioned purpose, embodiment of the present utility model is: all-hydraulic winch, include frame, rack-mounted HM Hydraulic Motor, drg and planetary reduction gear, be located at the outer capstan drum of planetary reduction gear, steel rope pressing plate on the capstan drum, it is characterized in that described be located at the outer capstan drum of planetary reduction gear be by self flange directly and the pinion carrier output shaft fix, and drive by the one-level planetary reduction gear; The steel rope pressing plate is located in the capstan drum and fixes with the reel flange.
Support to carry the leak free ball-bearing casing between described capstan drum and the bolster, and make axial limiting with shaft block ring.
The control cock of described capstan drum and HM Hydraulic Motor oil distributor are integrated.
The utility model has been made major tuneup at the defective of prior art, has solved the connection mode and the supporting structure of capstan drum and pinion carrier output shaft; The structural development that has overcome winch control cock and HM Hydraulic Motor oil distributor separately-loaded is integrated integrative-structure; And capstan drum is improved to by the one-level planetary reduction gear drives, thereby this all-hydraulic winch structure is simplified, volume-diminished is convenient to assembling, and cost reduces, and has improved functional reliability and driving efficiency.
To be elaborated again to concrete structure of the present utility model by the accompanying drawing embodiment that provides below.
Fig. 1 has provided the utility model overall structure scheme drawing.
Referring to Fig. 1, all-hydraulic winch has a frame (4), rack-mounted have HM Hydraulic Motor (2), drg (3) and a planetary reduction gear (6), capstan drum (5) is located at outside the planetary reduction gear, two flanges (11) that the welding one is arranged in the capstan drum, reel is fixed by the fastener of being made up of hex screw and spring washer with the flange of self pinion carrier output shaft (12) direct and planetary reduction gear, and is driven by the one-level planetary reduction gear.Simultaneously steel rope pressing plate (8) is changed to be located at and be connected with another flange (11) in the capstan drum, make designs simplification, volume-diminished.
Capstan drum (5) one end bearings are on planetary reduction gear (6), be to carry leak free ball journal spare (7) supporting between its other end and the bolster (9), and make axial location with shaft block ring (10), during installation with in the complete bearing hole that is fit into reel of transition fit.
Adopt the control cock and the integrated structure of HM Hydraulic Motor oil distributor (1) of capstan drum simultaneously, omitted the pipeline setting.
Claims (3)
1. all-hydraulic winch, include frame (4), rack-mounted HM Hydraulic Motor (2), drg (3) and planetary reduction gear (6), be located at the outer capstan drum (5) of planetary reduction gear, steel rope pressing plate (8) on the capstan drum, it is characterized in that the described outer capstan drum (5) of planetary reduction gear that is located at is that flange (11) by self is directly fixed with pinion carrier output shaft (12), and drive by the one-level planetary reduction gear; The steel rope pressing plate is located in the capstan drum and fixes with the reel flange.
2. all-hydraulic winch as claimed in claim 1 is characterized in that supporting to carry leak free ball-bearing casing (7) between described capstan drum (5) and the bolster (9), and makes axial limiting with shaft block ring (10).
3. all-hydraulic winch as claimed in claim 1 is characterized in that the control cock of described capstan drum (5) and HM Hydraulic Motor oil distributor (1) are integrated.
