detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail. As shown in Figures 1 and 2, a high-speed rail-type handling manipulator includes two mutually parallel guide rails 9 and a beam 8 straddling the two guide rails 9, the beam 8 is provided with a lifting device 1, the beam 8 Both ends are respectively provided with a trolley 10 for walking on the guide rail 9, and a driving device for driving the dolly 10 is provided on the two guide rails 9; the driving device includes a main drum 3 and a secondary drum 6 arranged at the right end of the guide rail 9, The main reel 3 is connected to the power source 16, and the driving gear 14 arranged on the main reel 3 meshes with the driven gear 18 arranged on the auxiliary reel 6; The right pulley block 12 at the right end of the guide rail 9 and the left pulley block 17 arranged at the left end of the guide rail 9 are connected to the left end of the dolly 10, and the secondary wire rope 13 wound on the auxiliary drum 6 is connected to the right end of the dolly 10.

The system is mainly used in ordinary industrial manufacturing workshops, where goods need to be transported at high speed, and the maximum average main speed is 10m/s.

The power source 16 in this embodiment is a hydraulic motor or an electric motor connected to the central shaft of the main drum 3 through a planetary gear train 15 . After the hydraulic motor or the motor is decelerated by the planetary gear train 15, the reel 3 is driven to rotate.

As shown in FIG. 3 , the cross-section of the beam 8 in this embodiment is shuttle-shaped, and the streamlined structure of the shape can greatly reduce the wind load and ensure the running speed.

Both ends of the main reel 3 and the auxiliary reel 6 in this embodiment are provided with hydraulic brakes 11, and the manipulator is braked by braking the reel.

Both ends of the guide rail 9 in this embodiment are provided with high-speed buffers 5 . During the movement of the manipulator, the breakage of the steel wire rope, the failure of the brake 11 and other human reasons may cause the manipulator to be out of control. Protective effects.

It also includes a synchronous control module 4 for controlling the synchronous operation of the drive devices on the two guide rails 9 . The utility model uses two sets of driving devices (one set of trolleys at both ends). In order to avoid uneven force on both ends of the beam 8, and because the span of the beam 8 is too large to use mechanical control for synchronous control, electrical signal synchronization is adopted. The control device 4 performs synchronous control to keep the trolleys 10 at both ends in sync at all times.

The hoisting device 1 of this embodiment adopts an electric hoist, and when carrying heavy objects, the heavy objects will be hooked and raised to the top to prevent the heavy objects from swinging during high-speed operation. Then the reel pulls the wire rope to drive the beam 8 to reciprocate on the guide rail 9 guide rails, wherein the guide rail 9 is supported by the bracket 7 .

It works like this:

Start-up stage: the electric hoist hooks the goods and rises to the top. At the same time, when the beam 8 needs to move to the left, the power source 16 (motor or motor) rotates forward, and after being decelerated by the planetary gear system 15, it drives the main drum 3 clockwise Direction rotation, the main steel wire rope 2 at the upper end is pulled by the main drum 3, one end of the main steel wire rope 2 is fixed on the main drum 3, and the other end is fixed on the left end of the trolley 10 through the right pulley block 12 and the left pulley block 17 (acting as a reversing role). 10 drives the beam 8 to move to the left along the guide rail 9. Since the main drum 3 and the auxiliary drum 6 are connected by a pair of meshing gears, when the main drum 3 rotates clockwise, the auxiliary drum 6 rotates counterclockwise, and the auxiliary drum 6 rotates counterclockwise. 6. At this time, the auxiliary steel wire rope 13 at the lower end is not pulled, so the auxiliary steel wire rope 13 is not stressed. In this process, the main drum 3 winds the wire rope and the auxiliary drum 6 puts the wire rope.

When the crossbeam 8 needs to move to the right, the power source 16 (motor or motor) rotates in the opposite direction. After being decelerated by the planetary gear system 15, it drives the main drum 3 to rotate counterclockwise. For meshing gear connection, when the main reel 3 rotates counterclockwise, the auxiliary reel 6 rotates clockwise. At this time, the auxiliary reel 6 pulls the auxiliary wire rope 13 at the lower end, and the auxiliary wire rope 13 pulls the trolley 10 to drive the beam 8 along the guide rail 9 directions. Movement to the right, the main drum 3 does not pull the main steel wire rope 2 at the upper end, so the main steel wire rope 2 at the upper end is not stressed. In this process, the auxiliary drum 6 winds the wire rope and the main drum 3 puts the wire rope.

Stable running stage: the power source 16 drives the main reel 3 to rotate clockwise or counterclockwise at a constant speed, and the main steel wire rope 2 or the auxiliary steel wire rope 13 pulls the trolley 10 to move smoothly on the guide rail 9 to the left or right.

Braking stage: the 8 hydraulic brakes 11 (four at one end) on the axis of the main drum 3 and the auxiliary drum 6 act simultaneously to generate braking torque. The specific way of braking: when the beam 8 moves to the left, each The hydraulic brake 11 on the reel rubs against the corresponding reel, so that the reel speed drops until it stops rotating. At this moment, the auxiliary steel wire rope 13 is stressed, and the traction crossbeam 8 is pulled to the right to make it stop moving to the left. When the crossbeam 8 moves to the right, the hydraulic brake 11 on each reel will rub against the corresponding reel, so that the reel speed will drop until it stops rotating. right movement.

If run into emergencies, as main wire rope 2 or auxiliary wire rope 13 fractures, brake 11 braking failures and other human causes cause the manipulator to break away from control, the mechanism can be emergency braked by the high-speed buffer 5 at guide rail 9 two ends.
