SU752036A1 - Multiway hydraulic distributor remote control apparatus - Google Patents

Description

The sprocket 5 of the drive 6 is clockwise, the catch 2 moves freely (slides) to the right along the teeth of the ratchet wheels 3, without switching the hydraulic distributors 1.

The leading sprocket 5 through the transducer 7, for example, a selsyn, is transmitted to the console 9, where by the pointer 8, the gripping positions control its approach to the desired hydraulic distributor 1. Then, the flexible link 4 is reversed from the console 9, as a result, the gripper 2 engages with the storage wheel of the selected hydraulic distributor and turns it to a predetermined angle (step) t, if it is necessary to turn the hydraulic distributor by the fifth step Z, then move to the left until the lth finger count Eve will not pass through the ratchet wheel 3 of the selected valve. Since the position of the gripper 2 distaiicioio is controlled on the console by pointer 8, the remaining grippers can be split practically at any required distance, but not more than the distance between adjacent hydraulic distribution valves, so it is difficult to remotely control the rotation of the hydraulic distributor at a given angle. To select the next control valve from the console 9, retrace the movement of the grip to the right, etc.

In cases where, according to the working conditions, it is necessary to have actuator displacements (hydraulic distributors relative to each other, the chain must be replaced with a thin cable with a grip, and the gear ratchet wheels can be replaced by fricciopimp ratchets. The essence of the device operation is preserved the movement of capture is carried out in one direction, control - in another).

The advantages of the device described are the simplicity of the system, the low

Accuracy of fabrication and installation, obtained through the adopted election principle (change in the direction of motion of the gripper); relatively high

the speed obtained due to the design of the gripping and settling it in two oppositely spaced areas, making the communication flexible in half (shortening the approach of the gripping to the desired hydraulic distributor). In addition, the device is driven by a drive that has two speeds: a high one for selecting a hydraulic distributor and a low one for switching the multidistributor. Later also increases

reliability of the system. It does not require high precision control of the position of the grip, since accurate switching of the hydraulic distributor is achieved due to the co-adjustment of the grip, guiding

and the profile of the teeth of the ratchet wheel and does not depend on the accuracy of the remote control and the gripping ability.
