Abstract

The invention discloses a mining hydraulic chain block of a monorail crane and belongs to the technical field of engineering machinery. The mining hydraulic chain block of the monorail crane comprises a transmission shaft, bearings, bearing sleeves, a beam body, a sprocket and a hydraulic motor, the end face of the beam body is in the shape of a groove with a downward opening, the hydraulic motor is fixed on a ring plate by bolts, the ring plate is welded on the beam body, two holes are reserved on the beam body, the bearing sleeves are welded in the two holes, and the bearings are arranged inside the bearing sleeves and support the transmission shaft which is in key connection with the sprocket. The mining hydraulic chain block of the monorail crane has the advantages that the beam body serves as a shell of the hydraulic chain block, thereby materials are saved while occupied area is small; the mining hydraulic chain block is free of oiling by the aid of the adopted self-lubricating bearings, simple in design structure and quite convenient to process and use, and wear among the bearing sleeves, the transmission shaft and the self-lubricating bearings is reduced; and the hydraulic motor is a large-torque hydraulic motor and can be used for carrying weights.

Description

A kind of mining monorail crane hydraulic hoist
Technical field
The present invention relates to a kind of hydraulic hoist, specifically a kind of mining monorail crane hydraulic hoist, belongs to mining machinery technical field.
Background technology
Hydraulic hoist is conventional weight lifting tool.At present, there are two kinds of situations in hydraulic hoist: a kind of housing volume is comparatively large, occupies a large amount of spaces, and is placed in outside beam body, hamper layout and the design of other parts; Insert in beam body though another kind of, but complex structure, exist and comparatively strict with beam body coordinate requirement, processing inconvenience.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of mining monorail crane hydraulic hoist, take up room little, structure is simple, easy to process.
To achieve these goals, the technical solution used in the present invention is: a kind of mining monorail crane hydraulic hoist, comprise power transmission shaft, bearing, axle sleeve, Liang Ti, sprocket wheel and hydraulic motor, the end face of beam body is the flute profile that Open Side Down, and hydraulic motor is fixed by bolts in Circular Plate, Circular Plate is welded on Liang Tishang, be provided with holes at Liang Tishang, axle sleeve is welded in holes, and axle sleeve inside arranges bearing, bearings power transmission shaft, power transmission shaft is connected with sprocket wheel by key.
Further, bearing is self-lubricating bearing.
Beneficial effect is: only have hydraulic motor to be arranged at the outside of beam body, and miscellaneous part is all directly insert in beam body, namely using the housing of beam body as hydraulic hoist, not only saves material but also takes up room little.Adopt self-lubricating bearing not need oiling, project organization is simple, use and process all very convenient, also reduce axle sleeve, wearing and tearing between power transmission shaft and self-lubricating bearing simultaneously.Hydraulic motor provides power to drive power transmission shaft to rotate, and simultaneously also for sprocket wheel provides moment of torsion, thus realizes the lifting of material.Because hydraulic motor adopts high pulling torque motor, can be used for the delivery of weight.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, power transmission shaft, 2, bearing, 3, axle sleeve, 4, Liang Ti, 5, sprocket wheel, 6, Circular Plate, 7, hydraulic motor, 8, hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of mining monorail crane hydraulic hoist of the present invention, comprise power transmission shaft 1, bearing 2, axle sleeve 3, beam body 4, sprocket wheel 5 and hydraulic motor 7, the end face of beam body 4 is flute profiles that Open Side Down, and hydraulic motor 7 is fixed by bolts in Circular Plate 6, Circular Plate 6 is welded on beam body 4, beam body 4 is provided with holes 8, and axle sleeve 3 is welded in holes 8, and axle sleeve 3 inside arranges bearing 2, bearing 2 supporting shaft 1, power transmission shaft 1 is connected with sprocket wheel 5 by key.
Only have hydraulic motor 7 to be arranged at the outside of beam body 4 in the present invention, miscellaneous part is all directly insert in beam body 4, namely using the housing of beam body 4 as hydraulic hoist, not only save material and the space that takies little.
The present invention adopts the hydraulic motor 7 of high pulling torque as power, for avoiding hydraulic motor 7 step to the interference of beam body 4, beam body 4 welding Circular Plate 6, is got up by hydraulic motor 7 by bolt support.Beam body 4 is opened holes 8, and axle sleeve 3 is welded in holes 8, and its bottom bracket axle 3 and bearing 2 adopt interference fit to pound into.Namely axle sleeve 3 is first welded in the hole 8 of beam body 4, and being pounded by bearing 2, the hole 8 into axle sleeve 3 is inner, and the two would not come off for interference fit.Result is exactly the inner rigid bearing 2 of axle sleeve 3, simultaneously bearing 2 supporting shaft 1.
Because bearing 2 for self-lubricating axle, not only can not need oiling and use easily, also reduce axle sleeve 3, wearing and tearing between power transmission shaft 1 and bearing 2 simultaneously.Hydraulic motor 7 provides power to drive power transmission shaft 1 to rotate, and simultaneously also for sprocket wheel 5 provides moment of torsion, thus realizes the lifting of material.Because hydraulic motor 7 adopts high pulling torque motor, can be used for the delivery of weight.
