RU69009U1 - VIBRATION MOTOR FOR PIPELINES - Google Patents

Abstract

Usage: propulsors for movement on the inner surface of pipelines.

The objective of the utility model is to reduce design complexity.

The inventive vibrating mover consists of a trolley 1, on which the drive casing 2 is mounted. Inside the casing 2, the winding of the electromagnet 3 is stationary, electrically connected to the control system 4. When voltage is applied to the winding of the electromagnet 3, an electromagnetic force arises, under the influence of this force, the armature 5 moves. The result is an inertia force greater in magnitude than the rolling friction force of the trolley 1 over surface 11, and the device begins to move. When the voltage is removed from the winding of the electromagnet 3, the armature 5 returns to its original position under the action of the elastic elements 6. As a result, an inertial force arises opposite to the original direction. In this case, the wheels 7 begin to rotate in the opposite direction, the dog 10 enters the groove of the ratchet wheel 9, the wheels 7 are jammed and the carriage 1 stops, since the friction force of sliding of the carriage 1 on the surface 11 is much greater than the inertia force. Thus, the device performs a rectilinear movement in one direction.

Benefit: enhanced functionality.

Description

The invention relates to devices for moving along the inner surface of pipelines and can be used to clean the inner surfaces of pipelines.

Known vibration drive for moving a vehicle, including an inertial-pulse converter and a pusher (see RF patent No. 2047001, IPC F03G), in which translational motion is carried out by transmitting a pulse of rotating inertial masses to the pusher.

The disadvantage of this device is that it has a low efficiency.

Known vibration drive, which includes a drive in the form of an inertial-pulse converter with inertial rotating masses and a mechanism for changing the radius of their rotation and a pusher with a reciprocating movement mechanism (see RF patent No. 2274574, B62D 57/00, BI No. 11, 20.04. 2006).

The disadvantage of this device is the design complexity due to the presence of a significant number of kinematically interconnected parts of the mechanisms.

The objective of the utility model is to reduce design complexity.

This object is achieved by the fact that in the known device including the drive, the drive is mounted on the transport part and is made in the form of an electromagnet, the winding of which is fixedly mounted on the body, the anchor is suspended on elastic elements that are guides for the anchor, the electromagnet winding is electrically connected to the system control, and the transport part includes a trolley mounted on wheels equipped with ratchet mechanisms.

The claimed technical solution differs from the prototype in that the drive is mounted on the transport part and is made in the form of an electromagnet, the winding of which is fixedly mounted on the body, the anchor is suspended on elastic elements that are guides for the anchor, the electromagnet winding is electrically connected to the control system, and the transport part includes a trolley mounted on wheels equipped with ratchet mechanisms.

Distinctive features in the claimed technical solution were not identified when studying this and related areas of technology.

The combination of the claimed features ensures the achievement of the objective of the utility model - reducing the complexity of the design.

Figure 1 shows a General view of the proposed device, figure 2 is a diagram of a ratchet mechanism.

The vibrating mover consists of a trolley 1, on which the drive casing 2 is mounted. Inside the casing 2, the winding of the electromagnet 3 is fixedly mounted electrically connected to the control system 4. The internal mass (anchor) 5 is suspended on elastic elements 6, which are guides for the anchor and are mounted on case 2. The truck 1 is mounted on wheels 7, on the shafts 8 of which ratchet mechanisms are installed, consisting of a ratchet wheel 9 and a dog 10. The truck moves along the surface 11.

Vibration mover operates as follows. When voltage is applied to the winding of the electromagnet 3, an electromagnetic force occurs, under the influence of this force, the armature 5 moves. The result is an inertia force 6, greater in magnitude than the rolling friction force of the trolley 1 on the surface 11, and the device begins to move. When the voltage is removed from the winding of the electromagnet 3, the armature 5 returns to its original position under the action of the elastic elements 6. As a result, an inertial force arises opposite to the original direction. In this case, the wheels 7 begin to rotate in the opposite direction, the dog 10 enters the groove of the ratchet wheel 9, the wheels 7 become jammed and the carriage 1 stops, since the friction force of sliding of the carriage 1 on the surface 11 is much greater than the inertia force. Thus, the device performs a rectilinear movement in one direction. The control system 4 allows you to set the law of movement of the armature 5, by changing the frequency, amplitude and shape of the voltage signal supplied to the winding 3 of the electromagnet.

Using the proposed device can improve the controllability of the movement process, which expands the functionality of its use.
