Description

A kind of chair of spreading machine slip location locking mechanism

Technical field

The utility model relates to pavement construction engineering machinery, particularly a kind of chair of spreading machine slip location locking mechanism.

Background technology

Paver is the special equipment for laying of roadway, maintenance of surface and transformation, its operating principle is: main frame is transported to screw material-distributing mechanism by conveying system by the laying of roadway material of truck, and screw material-distributing mechanism is evenly distributed in laying of roadway material within the scope of ironing width; Main frame plays the function that drives whole surface consolidation system to advance and walk by projected route simultaneously, and under the tractive force of main frame, ironing is floated on laying of roadway material and by laying of roadway material pre-compacted and strikes off.The laying of roadway efficiency of paver is very high, so paver is contemporary urban road laying construction and large area maintenance, transforms requisite engineering equipment.

Paver in the process of construction, because the width of main frame generally can be less than construction width, thus when tractor driver at main hands-operation machine time sight line can be subject to the restriction of hosting space.So, be necessary to design a kind of mechanism that tractor driver can be put into beyond hosting space and allow the understanding complete machine Construction Condition that it can be very safe.The present utility model is a kind of chair of spreading machine slip location locking mechanism, is exactly the sight line for the expansion paver tractor driver of safety.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of simple in structure, safe and reliable and increase the chair of spreading machine slip location locking mechanism of paver tractor driver's visual range.

The purpose of this utility model is achieved through the following technical solutions: a kind of chair of spreading machine slip location locking mechanism, it comprise Connection Block, foot-operated case, seat, bar hole, junction plate handle and backstay,, described Connection Block is connected with foot-operated case by sliding guide, the top of foot-operated case is fixed with seat, Connection Block inside offers bar hole, and a side of bar hole offers a plurality of locating notches; Junction plate is " L " character form structure, one end of junction plate is fixed on foot-operated case by fixture, the other end of junction plate is connected with handle by fixture, between junction plate and handle, be fixed with Compress Spring, the end of handle is connected with one end of backstay, the other end of backstay stretches into bar hole inside, and coordinates with locating notch.

The axis of described sliding guide and the center line of bar hole are parallel to each other.

Described Compress Spring is cylindroid helical-coil compression spring.

Described fixture comprises full thread hex bolts, spring washer and plain washer.

The utlity model has following advantage:

1, by the relative sliding of foot-operated case and sliding guide, can make seat move left and right, simple in structure, easy to use.

2, tight latch mechanism can make whole seat automatically locate and lock, and has increased stability and safety.

3, seat moves the field range that can change operating personnel, makes operating personnel's field range wider.
