Abstract
The utility model discloses an internally-mounted sensor mounting mechanism of a reverse hanging type hydraulic headstock gear. The mechanism comprises a cylinder barrel, a piston rod, a piston and a bottom cover, wherein the end portion of the piston is provided with a threaded connecting opening communicated with an oil inlet channel, a support is mounted on the threaded connecting opening, an axial through hole communicated with the threaded connecting opening is formed in the support, a connecting disc is fixedly mounted inside the bottom cover, the mechanism further comprises an encoder mounted on a shield, a steel wire rope is wound on a rotating shaft of the encoder, and the front end of the steel wire rope downwards penetrates through the axial through hole in the support, the threaded connecting opening and the oil inlet channel in sequence and then is fixedly connected to the connecting disc. The internally-mounted sensor mounting mechanism is reasonable and reliable in structure, the oil inlet channel of the cylinder barrel of the reverse hanging type hydraulic headstock gear is used as a lifting channel of the steel wire rope, the rusting and breaking phenomenon caused by the fact that the steel wire rope is exposed out of the reverse hanging type hydraulic headstock gear is avoided, normal work of the reverse hanging type hydraulic headstock gear is ensured, and reliable data are also provided for normal monitoring of a gate.
Description
Technical field
The utility model relates to inverted hydraulic lift field, specifically a kind of built-in sensor attachment mechanism of inverted hydraulic lift.
Background technology
Hydraulic hoist is controlled the lifting of all kinds of gates for all kinds of large-scale plumbing, Hydraulic and Hydro-Power Engineering, to reach the object of open and close.
In some water conservancy projectss, according to the needs of installing space, need to adopt inverted hydraulic lift, also avoid more than cylinder block is exposed at dam crest outward, being conducive to the attractive in appearance of dam crest.For guaranteeing the normal work of inverted hydraulic lift, generally at inverted hydraulic lift, external device for detecting distance of travel is installed, on the connection of wire rope one end and gate, the other end forms a sensor, the stroke of Real-Time Monitoring gate on encoder.But the wire rope of this structure exposes setting conventionally, be vulnerable to outside interference generation maloperation, long-term work simultaneously can produce corrosion in water environment, even ruptures.
Utility model content
The purpose of this utility model is to provide a kind of built-in sensor attachment mechanism of inverted hydraulic lift, utilize in the cylinder barrel of inverted hydraulic lift and itself there is oil inlet passage as the hoist trunk of wire rope, outer and corrosion, fracture occur to avoid wire rope to be exposed at inverted hydraulic lift outward.
The technical solution of the utility model is as follows:
A kind of built-in sensor attachment mechanism of inverted hydraulic lift, include cylinder barrel, piston rod, piston and bottom, on described piston rod, be respectively equipped with into, oil-out, piston rod and piston are provided with the oil inlet passage connecting and lead to cylinder barrel rodless cavity, piston rod is provided with the oil discharge passage that leads to cylinder barrel rod chamber, it is characterized in that: the end of described piston is provided with the mouth that is threaded being connected with oil inlet passage, on the described mouth that is threaded, bearing is installed, described bearing is provided with the axially extending bore being connected with the mouth that is threaded, the inner side of described bottom is installed with terminal pad, include the encoder being arranged on guard shield, in the rotating shaft of described encoder, be wound with wire rope, the front end of described wire rope is downwards successively through being fixedly connected on described terminal pad after the axially extending bore on bearing, be threaded mouth and oil inlet passage.
The built-in sensor attachment mechanism of described inverted hydraulic lift, is characterized in that: on the outer wall of described cylinder barrel, be fixedly welded with mount pad.
The built-in sensor attachment mechanism of described inverted hydraulic lift, is characterized in that: the upper end of described piston rod is provided with flange.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, reliable, utilize in the cylinder barrel of inverted hydraulic lift and itself there is oil inlet passage as the hoist trunk of wire rope, avoided wire rope to be exposed at inverted hydraulic lift outward the phenomenon of corrosion, fracture has occurred outward, not only guaranteed the normal work of inverted hydraulic lift, also the normal monitoring for gate provides reliable data.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
