The joint-balancing manipulator SBM-150M generally consists of a drive head mounted on a supporting structure, with the help of a pivoting device that provides 360-degree rotation of the head. The drive head has a hinged boom consisting of a shoulder and an arm. At the end of the arm, the head of the grip is installed. The gripper head can rotate around a vertical axis. The handle mounted on the head of the gripper is used to control the vertical movement of the gripper head, as well as to transfer the efforts of the worker to the load and boom during the horizontal movement of the gripper head. There is a clip on the head of the gripper, which serves to secure replaceable load-grabbing devices. The drive of the lifting mechanism is mounted on the drive head, consisting of a gear motor and a rack-and-pinion device that provides vertical movement of the grab head with the load. The vertical movement speed is controlled by a worker, who must turn the control handle at the same time. When the long end of the handle is turned up, the load also begins to move up, when the long end of the handle is turned down, the load also begins to move down. The speed of movement of the load depends on the angle of rotation of the handle. The lever system of the manipulator boom is balanced using a spring device and is designed so that the movement of the grip head in the radial direction to and from the pivot device occurs horizontally (using the mechanism of the hinge-lever pantograph). Therefore, the movement of cargo in the horizontal plane is carried out with minimal effort. The weight of the cargo is not felt. It is only necessary to overcome its inertia, depending on the weight and size of the load. When the control handle is released by the worker, it itself is set to a neutral horizontal position under the action of a spring. The load stops at this moment and is held by the lifting mechanism for as long as necessary. There is no radial and tangential movement of the grip head, and the load remains at the rear point of the space. The support-rotary device and the gripper head are assembled on rolling bearings, therefore, the rotation of the load around the axis of the gripper head and the rotation of the boom with the load around the axis of the support-rotary device require minimal effort. The manipulator allows you to service the zone.The electric drive of the lifting mechanism of the manipulator head is made using an electric brake motor and a frequency converter, which makes it possible to smoothly regulate the speed of vertical movements.
The manipulator has way switches for vertical movement height.
The manipulator is equipped with a light alarm "IF on", an indicator of connection to the network, an emergency button "ACCIDENT" placed on the arm, near the control handle. When the button is pressed, the load stops at the height at which it is at the moment of pressing the button.
Cargo movement can be controlled with one hand. Training to work with the manipulator takes several hours.
It is possible to simultaneously use several manipulators with loads of the long-gauge type (rails, beams, pipes).
The attachment of the gripping device on the head of the gripper is rigid, therefore it is possible to fix the load on the console (with a slight decrease in load capacity), which makes it possible to use the manipulator for servicing suspended containers, machine tools, presses, furnaces and other technological and transport devices with parts protruding from above, overlapping the working area. The use of eletrotals, crane beams, overhead cranes with a standard cable suspension of a hook cage is difficult or impossible in these cases.
