Abstract

The invention discloses a lever control operating rod mechanism which comprises an operating rod, an L-shaped lever, a push rod, an electric push rod, a proportional valve and a precise spherical hinge. The lever control operating rod mechanism can realize the movement of the operating rod in four directions by two groups of electric push rods. The displacement of each electric push rod determines the movement of the operating rod, and the control is accurate. The invention has smart structure, realizes the transverse movement of the operating rod by utilizing the lever principle and has simple manufacture.

Description

Lever control operating rod mechanism

Technical Field

The invention relates to the field of automatic transformation, in particular to a lever control operating rod mechanism.

Technical Field

With the trend of industrial operation towards being unmanned, the work safety is more and more emphasized, operators in dangerous work environments can be liberated, and the potential problems can be perfectly solved by controlling the operating rod by a remote control or automatic operation method.

However, the existing remote control operation rod technology occupies a large amount of space, needs higher capital, and has the defects of inaccurate control and the like. Remote control such as triple-play requires a control method of the entire apparatus to be changed, and thus requires a particularly large capital. Such as laterally adding a point push rod, this method has a disadvantage of occupying a large amount of space. If the control is directly carried out by a remote control universal push rod, the control precision of the method is too low and the control cannot be carried out at a low speed.

Disclosure of Invention

In order to solve the problems in the background art, the invention provides a lever control operating rod mechanism. Mainly to the problem that mechanical type action bars in each field can not long-range automatically controlled, through reasonable scheme, design and make a set of complete mechanical structure, the long-range automatically controlled of solution mechanical type action bar that can be perfect can make a contribution in the mechanical vehicle of future mill drives.

The invention adopts the following technical scheme:

the utility model provides a lever control action bars mechanism, includes action bars, L type lever, push rod, electric push rod, proportional valve, accurate ball pivot, action bars and L type lever fixed connection, two extreme points of L type lever pass through accurate ball pivot with two push rods respectively and articulate, the other end and the electric push rod of push rod pass through hinged joint, and the bottom of electric push rod is fixed.

In the above technical scheme, further, be equipped with universal hinge between action bars and the proportional valve, the bottom of proportional valve is fixed.

Furthermore, the push rod moves up and down to drive the L-shaped lever to tilt, so that the operating rod is driven to tilt, and the proportional valve is controlled to complete electric control operation.

The invention also provides a control mechanism which comprises at least two lever control operating rod mechanisms.

The invention has the beneficial effects that:

the electric control lever control operating rod mechanism utilizes the lever principle as power for driving the operating rod, and utilizes the electric push rod to push the lever to do tilting motion so as to control the tilting of the operating rod. The four-direction movement of the operating rod can be realized only by two groups of electric push rods, and the four-direction movement control device has the advantages of simple structure, low manufacturing cost, strong practicability and small occupied space.

FIG. 1 is a schematic diagram of the apparatus of the present invention;

wherein, 1 is an operating rod, 2 is an L-shaped lever, 3 is a push rod, 4 is an electric push rod, 5 is a proportional valve, and 6 is a precision spherical hinge.

Detailed Description

The method and apparatus of the present invention are further described below with reference to the accompanying drawings.

As shown in fig. 1, the lever control operation rod mechanism of the present invention includes an operation rod 1, an L-shaped lever 2, push rods 3, an electric push rod 4, a proportional valve 5, and a precision spherical hinge 6, wherein the operation rod 1 is fixedly connected to the L-shaped lever 2, two end points of the L-shaped lever 2 are respectively hinged to the two push rods 3 through the precision spherical hinge 6, the other end of the push rod 3 is connected to the electric push rod 4 through the hinge, and the electric push rod 4 is independently fixed in space. A universal hinge is arranged between the operating rod 1 and the proportional valve 5, and the bottom of the proportional valve 5 is fixed.

The power source of the lever control operating rod mechanism is two electric push rods 4, the movement amount of the push rod 3 is accurately controlled by the electric push rods 4, and the electric push rods 4 and the push rod 3 are connected through hinges, so that the error movement amount is reduced. The push rod 3 moves up and down to drive the L-shaped lever 2 to tilt, so that the operating rod 1 is driven to tilt, and the proportional valve 5 is controlled to complete electric control operation. The operation rod 1 moves forward, backward, leftward and rightward due to the principle of a lever. The structure is simple and compact, the electric push rod dosage is calculated, and the fixed and reliable control effect can be achieved.

The specific action is that the electric push rod 4 receives an electric signal given by the control center, so that fixed displacement is realized, the push rod 3 is driven to move upwards, the operating rod is inclined towards the pushing direction by the lever principle, and if the movement in the opposite direction is required, the electric push rod is controlled to descend. Electric push rod 4 can use servo electric push rod, and its control effect is accurate, can reach the effect of accurate control action bars mechanism.
