Abstract

The utility model belongs to the control technique of engineering machinery, which mainly comprises a drive mechanism and a rack bar positioning device, wherein the drive mechanism is provided with a sliding handle, a gear and a rack bar; the gear is supported on a casing, and a gear shaft of the gear extends from the casing and is connected with the handle into a whole; the rack bar is supported in the casing and meshed with the gear; one end of a flexible shaft is connected with the rack bar, and the other end of the flexible shaft is connected with a machine which needs to be controlled; the rack bar positioning device is arranged on the upper end of the casing, and at the position corresponds to the rack bar; the outer side of a push-and-pull handle seat is provided with a locking handle which can lock the gear. The utility model has the characteristics of simple and reasonable structure, small size, light weight, convenient arrangement and installation, portability and flexibility.

Description

Engineering machinery push-and-pull flexible axle controller

The utility model belongs to engineering machinery control technology, mainly proposes a kind of engineering machinery push-and-pull flexible axle controller, is used for the control that mechanisms such as the turning to of construction machinery product, commutation, lifting, speed change use the push-and-pull flexible axle.

At present, the operating mechanism of domestic engineering machinery also rests on 70 years levels, generally be hardware type, operator can not moving linearly, all needs by pull bar and passes a bridge as fulcrum, and operate with hand or hand-foot linked form, therefore the structure of controller is also different with the difference of operator, so its structure exists comparatively complicated, operation piece is difficult for reasonable Arrangement, very inconvenient shortcoming during manipulation.

The purpose that the utility model proposes engineering machinery push-and-pull flexible axle controller promptly is that it is had is simple and reasonable, is easy to arrange install, and especially handles the characteristics of light and flexible, thereby overcomes the existing shortcoming of above-mentioned operating mechanism.

The utility model is finished the technological scheme that its invention task takes: the driving mechanism and the positioning device that mainly include drawing handle, gear rack; Gear support can be made axial rotation on housing, thereby gear shaft stretches out housing and is connected with drawing handle with the handle set of drawing handle and is connected as a single entity, tooth bar is bearing in the housing and gear engagement, it can stretch out housing by the perforate of housing and also seesaw, push-and-pull flexible axle one end is connected on the tooth bar, and the other end connects the engineering machinery of required control.

Positioning device is installed in housing upper end and the corresponding position of tooth bar, and it mainly is made up of holding down bolt and the spring and the steel ball that are arranged in the holding down bolt endoporus, and sets positioning groove in the tooth bar relevant position.

One set lever can be set, and it is installed in the handle set outside of drawing handle, and set lever fuses with the screw of screw on its handle set and fixed gear, when screwing gear is played the locking effect.

Controller is fixed on the instrument panel of machinery by the housing screw, and dismounting is very convenient.

The utility model structural design advantages of simple, have in light weight, volume is little and handle the characteristics of light and flexible, and positioning device is housed on housing, and tooth bar is played positioning action.Set lever is that driving gear is locked, avoid release handle occurring and flexible axle from the phenomenon of line slip.

The accompanying drawing that the utility model embodiment provides is:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model drive mechanism schematic representation.

Accompanying drawing 3 is a tooth bar positioning device schematic representation.

The embodiment who provides is in conjunction with the accompanying drawings further specified the utility model;

Structure as shown in drawings: the utility model mainly includes the driving mechanism of drawing handle 1, gear 4, tooth bar 5, tooth bar positioning device 3, gear 4 is bearing on the involutory housing in the left and right sides 6, the handle set of drawing handle 1 connects with the splined shaft that gear stretches out housing, tooth bar 5 is bearing in the housing and also seesaws with gear 4 engagements and by the extended housing of opening in shell, push-and-pull flexible axle one end is assemblied in the M6 pull bar in the axis hole of the left end of tooth bar 5 or right-hand member, and the other end connects the corresponding part of required control machinery; In housing 6 upper end perforates tooth bar positioning device 3 is set, it is mainly by holding down bolt 9, spring 10 in the holding down bolt endoporus and steel ball 11 are formed, corresponding site at tooth bar 5 sets the location groove, when rotating with gear, tooth bar is linearly moved to certain position thus, steel ball 11 advances in people's positioning groove under spring 10 effects, is located.

Set lever 2 is contained in drawing handle 1 outside, and the screw of its handle set and the screw of fixed gear 8 fuse.

If controller need not locked, can remove locking device and use the nut set screw, in case drawing handle withdraws.

7 is housing lid among the figure.
