Description

A horizontal and vertical bidirectional monorail device based on magnetorheological fluid

technical field

The invention relates to the field of small transport rails, in particular to a monorail device in horizontal and vertical directions based on magnetorheological fluid.

Background technique

With the development of rail technology, in addition to the basis of rail transportation, there are also small guide rails and micro guide rails in logistics, machinery, medical and other aspects. Among them, the double track can easily realize a 90° turn, but most of the single track is only one-way driving. Therefore, in express sorting and mechanical processing, horizontal and vertical two-way movement cannot be realized based on a single track. Although horizontal and vertical two-way movement can be realized based on a double track, it takes up a lot of space, and the arc is too large to cause space waste when turning.

As a new type of material, magnetorheological fluid has the advantages of strong applicability, small mass, low power loss, high frequency response, and the most suitable damping force combined with system conditions during use. It is widely used in automobiles, Building structures, offshore platforms, bridges and other fields. Chinese patent CN205222488U discloses a right-angle steering monorail steering machine, which drives an electric push rod to move through a motor, and then drives the rotating rail to rotate, so as to realize the right-angle steering of monorail transmission in the steering mechanism. Although this kind of device that uses a motor to drive the steering has the advantages of high precision and convenient adjustment, it may cause irreversible damage to the steering mechanism when the speed is too high when the steering is turned at a small angle and high speed. Wear and tear will reduce work efficiency.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

Example

As shown in Figures 1, 2 and 3, a magneto-rheological fluid-based horizontal and vertical bidirectional monorail device, the device includes a longitudinal monorail 1, a transverse monorail 3 and a steering mechanism; the steering mechanism is located in the longitudinal The intersection center of the single track 1 and the horizontal single track 2; the steering mechanism includes a rotating base 2, a housing 5, a magneto-rheological fluid 51, a controllable power supply 6 and a drive motor 8; the bottom of the rotating base 2 is set to rotate shaft; the outer side of the housing (5) is fixed with a coil 4; the housing 5 is welded on the rotating shaft so that the housing 5 and the coil 4 do not rotate with the rotation of the rotating base 2; the magnetic current The variable fluid 51 is located in the casing; there is a sealing rubber ring between the rotating shaft and the casing 5 to prevent the magneto-rheological fluid 51 from flowing out; the coil is connected to the controllable power supply 6; the driving motor 8 is connected to the The rotating base 2 is connected; the claw 7 moves on the longitudinal single track 1, the horizontal single track 2 and the rotating base 2; the longitudinal single track 1, the rotating base 2 and the horizontal single track 3 are located on the same level and the height unanimous.

As shown in Figures 1 and 3, grooves are processed on the longitudinal single track 1, the horizontal single track 3 and the rotating base 2, and the shape of the groove matches the shape of the protrusion on the claw 7, so that the claw 7 can only realize The groove moves in the plane without moving in the direction perpendicular to the plane of the track, which has better safety. And in the gap between the claw 7 and the vertical single track 1, the rotating base 2 and the horizontal single track 3, lubricating oil is regularly applied, and the contact surface is precision machined, which can reduce the friction between the track and the claw 7.

When the claw 7 moves from left to right from the horizontal single track 3 to the position of the rotating base 2 where the vertical single track 1 and the horizontal single track 3 intersect, the next step of the running direction of the claw 7 is controlled by the rotating chassis 2 . The target position of the claw 7 is above the vertical single track 1, then the drive motor 8 controls the rotating base 2 to rotate clockwise 90°, and the claw 7 moves upward along the vertical single track 1, thereby realizing the horizontal and vertical motion directions. The transformation makes it possible for a single track to run in both horizontal and vertical directions, which improves work efficiency on the basis of saving space. Moreover, due to the existence of the steering base 2, the longitudinal single track 1 and the transverse single track 3 can ensure that a plurality of claws 7 operate at the same time, further improving work efficiency.

As shown in FIG. 2 , while the rotating base 2 is rotating, the controllable power supply 6 externally connected to the coil 4 generates a current to provide current to the coil 4 to generate a magnetic field. Since the coil 4 is tightly wound on the casing 5 in a helical shape, the direction of the generated magnetic field is parallel to the direction of the rotation axis, so that the magneto-rheological fluid 51 generates shear stress perpendicular to the direction of the rotation axis. When the rotating base 2 rotates, the rotating speed is controlled to prevent irreversible damage to the rotating base 2 caused by too fast rotating speed, so that the steering mechanism is more reliable and the service life of the steering mechanism is increased.

It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present invention without creative effort.
