Abstract

The utility model relates to an operation control device of crane. A base frame is in a cube framework shape, and a transmission mechanism has compact design, small volume, light weight and simple operation structure.The utility model has the technical characteristics that when a handle moves, a gear fan is driven to rotate by a crankshaft or a rotary frame, then the transmission gear rotates so as to make a spindle on the main controller rotate, realizing control to the contact switch.

Description

Crane control operation mechanism

Utility model belongs to the hoisting machinery operating control device.

At present, the control appliance of crane has hybrid combination control console, or master controller, cam controller, and the weak point that these several modes of operation exist is that the operating mechanism volume is big, operation effort, installation and maintenance inconvenience.

It is little that the purpose of this utility model provides a kind of volume, flexible operation, laborsaving, crane control operation mechanism easy to maintenance.

The utility model is achieved in that handle 18 is installed on the swivel mount 2, swivel mount 2 and bent axle 1 are installed on the pedestal 17 by bearing 3, tooth fan 5 is installed on bent axle or swivel mount, and the gear 6 on master controller 7 main shafts is fixed on the side of pedestal 17, and tooth is fanned 5 meshing gears 6; Another tooth fan 4 is installed on swivel mount 2 or the bent axle 1, the spur gear that 4 engagements of tooth fan and bevel gear 8 are coaxial, the bevel gear 9 that bevel gear 8 meshes on master controllers 10 main shafts.Axle 16 with the handle swing is installed on bent axle 1 or the swivel mount 2, be provided with two catch members 15 of symmetry in two sides of axle 16, catch members 15 is fixed on the pedestal 17 by axle 14, catch members 15 lower ends are connected by pin 13 with push rod 12, and spring 11 is sleeved on the telescopic push rod 12.

Compare with background technology, the beneficial effects of the utility model are:

1, pedestal is the cube frame moulding, and transmission mechanism is compact to design, and volume is little, and is in light weight, and operating structure is simple, uses reliable, easy to maintenance;

2, use operating grip after, can rebound automatically by spring resets, and has alleviated working strength of workers;

3, the utility model adopts gear, the transmission of tooth fan, transmission ratio-variable, and the control gear number of master controller is many.

Fig. 1 is a structural representation of the present utility model.

Be described further below in conjunction with embodiment.

Handle 18 360 ° of direction operations all around.When handle 18 front and back promote, drive tooth fan 5 by bent axle 1 or swivel mount 2 and rotate, travelling gear 6 rotates, thus the main shaft on the master controller 7 rotates, and realizes the control to contact switch.When handle 18 side-to-side movements, drive tooth fan 4 and rotate, thereby by the coaxial spur gear of transmission and bevel gear 8, bevel gear 8 is rotated, bevel gear 8 drive bevel gear 9 are rotated, and the main shaft that drives master controller 10 rotates, and can realize the control to another set of contact switch.

In transmission mechanism, tooth fan 4 also can be fanned 5 the kind of drive as tooth, the spur gear on the other cover master controller of direct transmission 7 main shafts, and the master controller of this mode transmission must be installed in the side of pedestal 17.

When operating grip 18 motions, drive axle 16 swings by swivel mount 2 and bent axle 1.As with catch members 15 when the left translation, the bottom of catch members 15 is withstood push rod 12 and is overcome spring force and move right; When lever operated end, spring 11 outwards ejects automatically, promotes catch members 15 bottoms and moves to left, and the upper end of catch members 15 then impeller-hub 16 moves to right, and drives handle 18 and resets.When axle 16 was passed another catch members to the right, the drive mechanism of Yin Ben mechanism was identical, and the action equidirectional is opposite, and symmetry is installed.
