Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Referring to fig. 1-5, the present embodiment provides a novel pneumatic switch of monorail crane. As shown in fig. 1, the pneumatic turnout includes a frame body 30, a third fixed way 60 is provided at a lower portion of one end of the frame body 30, and a first fixed way 40 and a second fixed way 50 are provided at a lower portion of the other end of the frame body 30, wherein the first fixed way 40 is an inclined way, the second fixed way 50 is a straight way, and the second fixed way 50 and the third fixed way 60 are on the same straight way. The lower part of the frame body 30 is further provided with a swing passage 20, a first end of the swing passage 20 is hinged with the third fixed passage 60, the swing passage is pushed by a cylinder 11 arranged on one side of the frame body 30 to realize swing, and when the swing passage 20 is in butt joint with the third fixed passage 60, the straight passage of a turnout is communicated; when the swing rail 20 is butted against the second fixed rail 50, the turnout of the turnout is conducted.

The lock device 10 provided in the present embodiment is used for position limitation when the swing path 20 swings to the straight path or the branch path, that is, by blocking the inward side of the connected swing path 20 to prevent it from swinging. The following embodiments can be referred to for specific construction of the locking device 10.

In a possible embodiment, the locking device 10 comprises a cylinder 11 fixed to the frame 30, and a slide 15 is also provided in the frame 30, optionally the slide 15 being provided in the middle of an upper one of the beams on the frame 30. Optionally, a sliding groove is provided in the sliding seat 15, and the extending direction of the sliding groove is the same as the direction of the straight track.

In some embodiments, two posts are disposed on the swinging road 20 near the second end thereof, namely, a first post 18 and a second post disposed at one side of the first post 18, and the two posts are used for limiting and blocking the swinging road 20.

In particular, a blocking element 14 is slidably arranged in a sliding slot of the slide 15, and a first blocking element 17 and a second blocking element 16 are respectively articulated on the top surface of the slide 15 along both sides of the sliding slot. The detent element 14 is in contact with the first detent element 17 and the second detent element 16 towards the end of the gate during the sliding movement. When the swinging road 20 swings to the straight road, the first blocking member 17 blocks the first upright post 18 from moving towards the inner side of the frame body by the tension of the first elastic member; when the swinging rail 20 swings to the turnout, the second stopper 16 stops the second upright post from moving towards the inner side of the frame body by tensioning the second elastic piece 19. Optionally, the blocking element 14 is driven by the movable block 12, and the movable block 12 is connected to a piston rod end of the cylinder 11, that is, the cylinder 11 pushes the movable block 12 to move, and then the movable block 12 acts on the blocking element 14, so that the blocking element 14 makes a linear motion in the sliding slot, and the blocking element 14 locks the position where the blocking element blocks the upright post during sliding or releases the blocking of the blocking element on the upright post. Optionally, a limit groove is formed on the movable block 12, and a fixing shaft is correspondingly arranged on the swing path 20, and the fixing shaft is movably arranged in the limit groove.

In the embodiment, the swing passage 20 is driven by one air cylinder 11, and in the driving process, the limit and the limit release of the swing passage 20 are also realized. Since the swinging channel 20 needs to be locked by the locking device 10 after the connection is completed, the locking device needs to be released in time when the channel needs to be changed. In the embodiment, a limit groove is arranged on the movable block 12. When the swing path 20 needs to be changed, the cylinder 11 needs to push or pull the movable block 12 to move an idle stroke, which means that the cylinder 11 does not act on the swing path 20 in the idle stroke, that is, the swing path 20 does not move, and in the idle stroke, the movable block 12 can drive the blocking member 14 to move in the sliding slot, so that the locking device 10 is released from the limit. The distance of the idle stroke in this embodiment is defined by the shape of the stopper groove.

In one possible embodiment, as shown in fig. 2, the blocking member 14 includes a connecting plate portion and a blocking portion 141, wherein the blocking portion 141 is connected below the first end of the connecting plate portion, the blocking portion 141 includes a first plate portion, a slant plate portion and a second plate portion, the first plate portion, the slant plate portion and the second plate portion are arranged in the same plane, the first plate portion and the second plate portion are staggered up and down and connected through the slant plate portion, two side planes of the first plate portion and two side planes of the second plate portion are arranged in parallel, and two outer side planes of the first plate portion and the second plate portion are respectively in contact with one side groove surface of the chute; the two inclined planes of the inclined plate part are arranged in parallel. That is, two sides of the clamping part are respectively formed into a plane-inclined plane-plane structure.

In a possible embodiment, the height of the detent 141 needs to be higher than the depth of the chute. Referring to fig. 5, alternatively, the first and second stoppers 17 and 16 on both sides of the sliding chute are of the same structure, and each include a cross bar 171 and a vertical bar 173 vertically disposed at the lower part of the first end of the cross bar 171, the second end of the cross bar 171 is hinged on the sliding seat 15, and the second end of the cross bar 171 is disposed in a plane and can be disposed coplanar with the inner side of the sliding chute; the outer side of the vertical rod 173 is used for blocking in front of the corresponding upright.

First and second elastic elements 19 are respectively provided on the first and second stops 17, 16, which are intended to pull the stops to remain blocked in front of the corresponding uprights, forming a block, when the abutment of the runway 20 is completed. When the first elastic member or the second elastic member 19 is in a normally contracted state, the plane on the first end of the corresponding cross bar 171 is attached to the inclined plane on the corresponding side of the blocking member 14 to lock the blocking position; when the first elastic member or the second elastic member 19 is in a stretched state, the plane on the first end of the corresponding cross bar 171 is attached to the outer plane of the corresponding side of the blocking member 14 to release the blocking of the vertical bar 173 to the upright.

Illustratively, in the starting position, the plane of the first end of the cross bar 171 is abutted against the inclined surface of the blocking portion 141, and at this time, the first blocking member 17 forms a block for the first upright post 18, and when the blocking portion 141 moves forward, the cross bar 171 rotates around its hinge shaft to make the plane of the first end of the cross bar 171 abut against the outer plane of the blocking portion 141, and at this time, the first blocking member 17 is separated from the first upright post 18 to release the limit.

Optionally, the side surface of the vertical rod 173 close to the corresponding upright column is provided with an arc surface, and the arc surface is in clearance fit with the outer wall of the corresponding upright column, i.e., a little fit clearance is left, so that the rotation blocking is prevented. The structure of the arc surface can realize line contact with the upright post, thereby ensuring reliable blocking.

Optionally, the central line of the arc surface is collinear with the hinge axis on the cross bar. This arrangement ensures that the blocking element does not deflect when it is on the slope of the detent 141, thus ensuring a reliable construction.

Referring to fig. 1, in the present embodiment, the movable block 12 is connected to one end of a connecting plate of the blocking member 14 through a connecting rod 13, and both ends of the connecting rod 13 are hinged. When the movable block 12 acts, the connecting rod 13 drives the blocking piece 14 to move in the sliding chute.

In some embodiments, the limiting groove on the movable block 12 is a square groove, and the length and width of the square groove are both greater than the diameter of the fixed shaft, i.e. the fixed shaft can move in the transverse direction and the longitudinal direction of the square groove, so that the swinging of the swinging channel and the movement of the clamping member can be realized.

In some possible embodiments, the first elastic member and the second elastic member 19 are provided as tension springs, and both ends of the tension springs are provided with drag hooks. Optionally, a first pin shaft 172 is fixedly arranged at the top of the cross rod 171, a second pin shaft is arranged on the two sides of the sliding groove of the sliding seat 15, and the drag hooks at the two ends of the tension spring are respectively connected to the first pin shaft 172 and the second pin shaft.

The invention also provides a locking method of the novel pneumatic turnout of the monorail crane, which comprises the following steps:

referring to fig. 2, when the swing path 20 is located to the straight path, i.e. when the swing path is in butt joint with the second fixed path 50, the fixed shaft abuts against the first wall in the limiting groove, the first elastic member tensions the blocking member 14 to block the first upright post 18 from moving toward the inside of the frame body, and the blocking member 14 locks the blocking position of the first blocking member 17.

That is, in the initial position, the plane of the first end of the cross bar 171 of the first blocking member 17 is abutted against the inclined plane of the blocking portion 141, and the first elastic member is tensioned, so that the first blocking member 17 is blocked in front of the first upright post 18, and the blocking of the swinging channel 20 is formed.

Referring to fig. 3, when the swing path 20 needs to be changed, the cylinder 11 first pushes the movable block 12 to move a set distance in the limiting groove to abut against the second wall of the limiting groove, and the connecting rod 13 pushes the blocking member 14 to move linearly along the sliding groove to release the blocking of the first upright post 18 by the first blocking member 17; then, the cylinder 11 continues to push the movable block 12 to move and drive the swinging channel 20 to swing.

That is, the cylinder 11 firstly runs through the idle stroke in the limit groove of the movable block 12, and in the idle stroke, the detent portion 141 pushes the first stop member 17 to rotate by an angle and to be attached to the outer plane of the detent portion, so as to release the limit of the first stop member 17; after the limit is released, the movable block 12 is pushed again, and at this time, the swinging channel 20 can be pushed to swing.

Referring to fig. 4, when the swinging rail 20 swings to the turnout, that is, when the swinging rail is in butt joint with the first fixed rail 40, the first blocking member 17 rotates to be blocked on the second upright column by the traction of the second elastic member 19 along with the movement of the blocking member 14, and the blocking position of the second blocking member 16 is locked by the blocking member 14.

That is, during the process that the air cylinder 11 continues to push the swinging channel 20 to move, the plane of the first end of the cross bar 171 of the second stopper 16 abuts against the outer plane of the other side of the blocking portion 141 and moves on the plane, when the swinging channel 20 swings and is completely butted with the first fixed channel 40, the second stopper 16 just runs to the connection position of the inclined plane and the plane, the blocking of the second upright column is realized through the traction of the second elastic member 19, and thus the position limitation of the swinging channel 20 is realized. When the swing path 20 needs to swing from the turnout to the straight path, the air cylinder 11 firstly pulls back an idle stroke to realize the spacing release, and then continues to pull the swing path 20 to move to the straight path position.
