Abstract

The utility model discloses a master controller, which comprises a driving gear and a driven gear mutually meshed. The driving gear is connected to one end of a driving rotary shaft and fixedly connected with an operation handle, the driven gear is connected with a cam rotary shaft which is provided with a plurality of cams, a plurality of contacts are arranged on one side or two sides of the cam rotary shaft, and each cam is provided with a plurality of technology holes. Since the technology holes are arranged on each cam, the angles of the cams can be conveniently and flexibly adjusted on site, the closure order of the contacts can be adjusted, and construction parameter can be changed without replacing the cams.

Description

Master controller

Technical field

The utility model relates to a kind of control device that is used for the activity of Control Engineering construction equipment, is specifically related to a kind of master controller.

Background technology

Master controller is widely used in the control system of various plant equipment, especially in engineering construction machinery, controls the comings and goings of this construction machinery by master controller.

Master controller generally includes operating grip, transmission device and closing of contact control system.During operation, generally drive driving gear by operating grip, engagement by driving gear and driven gear drives control rotating shaft again, cam bit is installed on the control rotating shaft, and the rotation of rotating shaft can drive the closure that cam bit is controlled electrical contact, thereby commands various predetermined construction actions by the electrical system of Control Engineering machinery.

There are following two significant drawbacks in the existing master controller that is used for construction machinery:

One, need fixed grade of operating grip is long-time, long stroke ground on certain ad-hoc location, this places certain position with handle with regard to the needs operating personnel for a long time and can not loose one's grip in work progress, cause operating personnel's working strength greatly, the hand fatiguability;

Two, under some operating mode occasion, need the field change closing of contact to change construction parameter in proper order; Though existing master controller also can be adjusted closing of contact order by changing cam bit, often need wait for the backward cam bit that manufacturer provides, latent period is long, does not have mobility.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of master controller, and it can change construction parameter under the situation of not changing cam bit.

For solving the problems of the technologies described above, the technical solution of the utility model master controller is:

Comprise intermeshing driving gear and driven gear; Driving gear connects an end of active rotating shaft; Driving gear is fixedlyed connected with operating grip; Driven gear connects the cam bit rotating shaft, and the cam bit rotating shaft is provided with a plurality of cam bits, and the one or both sides of cam bit rotating shaft are provided with a plurality of contacts; Described cam bit is provided with a plurality of fabrication holes.

Described a plurality of fabrication hole is with respect to the circumference uniform distribution of cam bit.

Described a plurality of cam bit axially fastens in the cam bit rotating shaft by the cam bit locking nut.

The other end of described active rotating shaft is fixedlyed connected with damping fin, and the both sides of damping fin are provided with fixed friction sheet and movable friction plate respectively, and the fixed friction sheet is regulated bolt by damping force and is connected with movable friction plate.

The technique effect that the utility model can reach is:

The utility model cam bit is provided with a plurality of fabrication holes, can be at the scene the angle of adjustment cam sheet easily and flexibly, thereby adjust the closing order of contact, be implemented under the situation of not changing cam bit and change construction parameter.

The utility model can make the working strength of operating personnel in work progress reduce greatly, also can change construction parameter more easily simultaneously, thereby shorten construction period greatly.

The utility model is provided with the damping fin of operating grip interlock, by adjusting the damping value between fixed friction sheet and the movable friction plate, thereby can make when decontroling operating grip after operating personnel place certain angle with operating grip, operating grip still stays in original position.

The utility model can solve the operating grip that has master controller now does not have fixed shelves operating function when operation problem.

Embodiment

As shown in Figure 1 and Figure 2, the utility model master controller comprises intermeshing driving gear 10 and driven gear 11; Driving gear 10 connects an end of active rotating shaft 2, active rotating shaft 2 and driving gear 10 interlocks; The other end of active rotating shaft 2 is fixedlyed connected with damping fin 3, and the both sides of damping fin 3 are provided with fixed friction sheet 6 and movable friction plate 4 respectively, and fixed friction sheet 6 is connected with movable friction plate 4 by damping force adjusting nut 5;

Driving gear 10 is fixedlyed connected with operating grip 1;

Active rotating shaft 2, operating grip 1 pass through to rivet one-body molded with driving gear 10.

During operation, damping fin 3 and movable friction plate 4 by regulating damping force adjusting nut 5, make fixed friction sheet 6 and movable friction plate 4 clamp damping fin 3 along with driving gear 10 moves together, make damping fin 3 produce required damping value, thereby realize required working condition requirement.By adjusting the damping value between fixed friction sheet 6 and the movable friction plate 4, can make operating grip 1 be positioned at the desired position arbitrarily.

Driven gear 11 connects cam bit rotating shaft 12, and cam bit rotating shaft 12 is provided with a plurality of cam bits 8, and the one or both sides of cam bit rotating shaft 12 are provided with a plurality of contacts 7;

A plurality of cam bits 8 axially fasten in cam bit rotating shaft 12 by cam bit locking nut 9;
