Description

Light master controller for crane

Technical Field

The utility model relates to an electrical equipment technical field especially relates to a light-duty master controller that hoist was used.

Background

The master controller is mainly used in the transmission device of the electric appliance, and contacts are switched on and off according to a certain sequence, so that the purposes of issuing commands or controlling circuit interlocking and switching are achieved. The master controller is suitable for frequently switching on and switching off a circuit, is often matched with a magnetic starter to carry out remote control on starting, braking, speed regulation and reversing of a motor, and is widely applied to control systems of various devices such as cranes and the like.

The master controller for the crane is influenced by the use occasion and environment, so that the variety is various. Cranes for steel, metallurgy, harbour are generally equipped with medium or heavy master controllers, while cranes at warehouses, cargo yards, etc. are generally equipped with light master controllers. The light master controller has the advantages of small operating force and simple structure, so the light master controller is widely arranged in occasions with infrequent operation and not severe working environment. With the prosperity of the logistics industry and the construction industry, the demand on the light master controller is more and more increased.

At present, most of light master controllers produced by domestic crane electric control manufacturers are formed by modifying medium master controllers, contact groups of the light master controllers are replaced by micro switches, the electric performance of the light master controllers cannot meet the national standard requirement of GB14048.5, false operation is easy to occur, potential safety hazards exist, and the market requirements cannot be met. Therefore, a new generation of light master controller needs to be developed and developed to meet the market demand.

SUMMERY OF THE UTILITY MODEL

The utility model provides a light-duty master controller that hoist was used, include: the device comprises a bottom plate (7), an operating handle (4), two groups of motion mechanisms and four groups of contact groups (2) which are arranged below the bottom plate (7);

the four groups of contact groups (2) are respectively fixedly connected with the bottom plate (7) through the four base frames (1), and the four groups of contact groups (2) are distributed below four edges of the bottom plate (7);

the two groups of motion mechanisms are distributed in a cross shape and comprise crankshafts (5) and cams (3) fixedly arranged at two ends of the crankshafts (5); the cam (3) is in contact with the corresponding contact group (2);

the operating handle (4) passes through the center of the base frame (1) and is respectively connected with the centers of the crankshafts (5) of the two groups of motion mechanisms.

Preferably, the operating handle (4) is sleeved with a dust cover (6).

Preferably, the operating handle (4) is provided with a zero self-locking mechanism.

Preferably, each set of motion mechanisms is provided with 3 gears.

The utility model provides a pair of light-duty master controller that hoist was used compares with prior art and has following advantage:

1. the operating handle of the master controller of the utility model is provided with a zero self-locking mechanism, thereby preventing misoperation and ensuring driving safety;

2. the utility model discloses have two motion, can realize four direction movements in the front, back, left and right sides.

3. The operating handle can be linked in four directions, and the simultaneous action of a cart and a trolley of the crane can be met.

Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.

Fig. 1 is a schematic structural diagram of a light master controller for a crane according to the present invention. As shown in fig. 1, an embodiment of the present invention provides a light master controller for a crane, including: the device comprises a bottom plate 7, an operating handle 4, two groups of motion mechanisms and four groups of contact groups 2, wherein the two groups of motion mechanisms are arranged below the bottom plate 7.

The four groups of contact groups 2 are respectively fixedly connected with the bottom plate 7 through the four base frames 1, the four groups of contact groups 2 are distributed below four edges of the bottom plate 7, and the four groups of contact groups 2 are distributed in a square shape.
