In the related art, a guide rail 1a of a conventional rail apparatus is shown in fig. 1; the running rails 2a are shown in fig. 2. When the guide wheels of the crown block 3a move in the direction of S1 on the first guide branch 100a, the running wheels of the crown block 3a move in the direction of S1 on the first main running road 20 a. As shown in fig. 3, if traffic jam occurs in the area a ahead of the travel switch 22a in the direction of S1, the guide wheels cannot be switched from the first guide branch 100a to the second guide branch 101a, and the track wheels cannot be switched from the first travel main lane 20a to the second travel main lane 21a, and traffic jam can be continued, which lowers the transport efficiency of the overhead traveling crane 3 a. Therefore, it is desirable to provide a new track device.
First, in an example embodiment of the present disclosure, a rail device of a crown block is provided. The crown block serves as a silicon wafer conveying device and can move back and forth between the manufacturing modules along the rail device.
The top of the crown block 14 is provided with a guide wheel, and the specification of the guide wheel is based on the matching with the guide rail 1000 of the rail device, which is not described in detail herein. The bottom of the crown block 14 on both sides is provided with running wheels, the specification of which is based on the running wheels can be matched with the running track 2000 of the track device, and the detailed description is omitted here. It should be noted that the guide wheel is reciprocally movable along a predetermined plane on the overhead traveling crane 14 so that the guide wheel can be switched from the guide main track 1 to the guide branch track 2 and the guidance of the overhead traveling crane 14 is realized.
As shown in fig. 4 and 5, the rail device may include a guide rail 1000 and a running rail 2000. Wherein:
the guide rail 1000 can be arranged on a mounting surface and comprises a guide main track 1 and a guide branch track 2; the guide main road 1 comprises a first guide branch road 100 and a second guide branch road 110 which are arranged in parallel; the guide fork 2 is connected between the first guide branch 100 and the second guide branch 110 for guiding the guide wheel to move from one of the first guide branch 100 and the second guide branch 110 to the other.
The running track 2000 is arranged on one side of the guide track 1000 away from the installation surface, and the running track 2000 comprises a running fork 5, a first running main road 3 and a second running main road 4 which are arranged side by side; the travel fork 5 is used to guide travel wheels to move from one of the first main travel lane 3 and the second main travel lane 4 to the other.
In the rail apparatus of the overhead traveling crane according to the embodiment of the present disclosure, when the traveling wheels of the overhead traveling crane 14 travel along the first main traveling road 3 in the direction of S1, the guide wheels of the overhead traveling crane 14 are switched from the first guide branch road 100 to the second guide branch road 110 via the guide branch road 2, and the traveling wheels are switched to the second main traveling road 4 via the traveling branch road 5; when the running wheels run on the first main running lane 3 in the direction of S2, the guide wheels of the crown block can be switched from the first guide branch 100 to the second guide branch 110 via the guide switch 2, and the running wheels can be switched to the second main running lane 4 via the running switch 5. Similarly, the running wheels of the crown block 14 can be switched to the first running main lane 3 when the second running main lane 4 runs in both the S1 direction and the S2 direction. If traffic jam occurs on any one of the traveling main roads, the crown block 14 can be switched to the other traveling main road to avoid the traffic jam area, thereby improving the transportation efficiency.
The components of the track device provided by the embodiment of the present disclosure are described in detail below with reference to the accompanying drawings:
as shown in fig. 4, the guide rail 1000 may cooperate with a guide wheel of the overhead traveling crane 14 and guide the overhead traveling crane 14 to turn. For example, the guide rail 1000 may have a groove or a protrusion, and the guide wheel is slidably fitted with the groove or the protrusion. Of course, the guide rail 1000 may have any other shape, which is not listed here.
The guide track 1000 can be provided on a mounting surface. The installation surface may be a floor surface, a wall surface, or a ceiling surface, or may be other surfaces as long as the guide rail 1000 can be installed, which is not illustrated herein.
The guide rail 1000 may include a guide main track 1 and a guide branch track 2, wherein the guide main track 1 may include a first guide branch track 100 and a second guide branch track 110 arranged in parallel.
For example, the first guide branch road 100 and the second guide branch road 110 can both extend along a straight line, and the distance between the first guide branch road 100 and the second guide branch road 110 is based on the matching with a guide wheel of the overhead travelling crane 14, which is not described in detail herein. Of course, the first guide branch road 100 and the second guide branch road 110 may also extend along a curve, and are not particularly limited herein.
The guide fork 2 may be connected between the first guide branch 100 and the second guide branch 110 for guiding the guide wheels to switch between the first guide branch 100 and the second guide branch 110.
For example, the guided turnout 2 may include a first fixed turnout 20, a second fixed turnout 21, a first rotating turnout 22, and a second rotating turnout 23, wherein:
the first fixed fork 20 may include first and second fork segments 200 and 201 spaced apart from each other and connected to the first and second guide branches 100 and 110, respectively. The second fixed branch 21 may also include a third branch 210 and a fourth branch 211, which are spaced apart from each other and are connected to the first guide branch 100 and the second guide branch 110, respectively. The extended lines of the first fixed branch 20 and the second fixed branch 21 intersect each other, and the fourth branch 211 and the first branch 200, the second branch 201, and the third branch 210 are all symmetrical about the central axis of the first guide branch 100 and the second guide branch 110.
The first rotating turnout 22 and the second rotating turnout 23 can be arranged between the first fixed turnout 20 and the second fixed turnout 21, and the first rotating turnout 22 and the second rotating turnout 23 are arranged opposite to each other at a preset distance. The first rotary switch 22 is rotatable between a fifth position and a sixth position, and the second rotary switch 23 is rotatable between a seventh position and an eighth position.
When the first rotary switch 22 is rotated to the fifth position, the second rotary switch 23 is rotated to the seventh position. At this time, the first rotating fork 22 is butted against the first fork section 200 and separated from the third fork section 210; the second rotating fork 23 is butted against the second fork segment 201 and is separated from the fourth fork segment 211; the guide wheel is movable between the first guide branch 100 and the second guide branch 110 via the first branch 200, the first rotating branch 22, the second rotating branch 23, and the second branch 201.
Similarly, when the first rotary switch 22 is rotated to the sixth position, the second rotary switch 23 is rotated to the eighth position. At this time, the first rotating fork 22 is butted against the third fork section 210 and separated from the first fork section 200; the second rotating fork 23 is butted against the fourth fork segment 211 and is separated from the second fork segment 201; the guide wheel is movable between the first guide branch 100 and the second guide branch 110 via the third branch 210, the first rotary branch 22, the second rotary branch 23 and the fourth branch 211.
It can be understood that the first branch 200, the second branch 201, the third branch 210, the fourth branch 211, and the first rotating branch 22 and the second rotating branch 23 can all extend along an arc-shaped track, so that the transition section is smooth, and smooth switching of the guide wheels is ensured. Of course, each portion of the guide fork 2 may extend along a straight track, and is not particularly limited herein.
It should be noted that the connection between each part of the guide fork 2 and the first guide branch 100 and the second guide branch 110 must be communicated to allow the guide wheel to move between the first guide branch 100 and the second guide branch 110.
In other embodiments of the present disclosure, the guide turnout 2 may be a track that is arranged crosswise, communicates with each other, and has an arc shape. At this time, the guide wheels may also move between the first guide branch 100 and the second guide branch 110. Of course, the guide fork 2 may be in other forms, and it is sufficient to guide the crown block 14 to switch between the first guide branch 100 and the second guide branch 110, which is not listed here.
As shown in fig. 5, the running rails 2000 may cooperate with running wheels of the crown block 14 and serve to support the crown block 14. For example, the running rail 2000 may have grooves or projections with which the running wheels are in sliding engagement. Of course, the running rail 2000 can also have any other shape, which is not further described here.
The running rail 2000 may be disposed on a side of the guide rail 1000 away from the installation surface, and parallel to the guide rail 1000. The distance separating travel rail 2000 and guide rail 1000 is determined by the relative positions of the guide wheels and travel wheels on crown block 14 and will not be described in detail herein.
The running rail 2000 may comprise a running fork 5 and a first and a second running main 3, 4 arranged side by side, wherein:
the first main running road 3 may comprise a first branch 30 and a second branch 31 able to cooperate with running wheels on both sides of the crown block 14, while the second main running road 4 may comprise a third branch 40 and a fourth branch 41 able to cooperate with running wheels on both sides of the crown block 14.
For example, the first branch passage 30 and the third branch passage 40 may be disposed in parallel and both extend in a straight line, and the second branch passage 31 and the fourth branch passage 41 may be located between the first branch passage 30 and the third branch passage 40.
Similarly, the fourth branch 41 also has a second break 410, the first end and the second end of the second break 410 are bent toward the first branch 30, and the fourth branch 41 and the second branch 31 are symmetrical about the central axes of the first branch 30 and the third branch 40, so that the running wheels can move along the third branch 40 and the fourth branch 41.
Of course, the first branch 30 and the third branch 40 may also extend along a curve, which will not be described in detail herein.
The travel fork 5 is used to guide travel wheels to move from one of the first main travel lane 3 and the second main travel lane 4 to the other.
For example, the travel fork 5 may be provided between the first branch 30 and the third branch 40, and may include a first fork 50 and a second fork 51. The first branch 50 is rotatable between a first position and a second position, and the second branch 51 is rotatable between a third position and a fourth position.
When the first branch 50 is rotated to the first position, the second branch 51 is rotated to the third position. At this time, the first branch 50 is butted against the first end of the first discontinuity 310 and extends toward the third branch 40; the second branch 51 is butted with a second end of the second fracture 410 and extends toward the first branch 30; one row of wheels of the double row of running wheels is moved to the first branch 30 via the fourth branch 41 and the second branch 51, and the other row of wheels is moved to the second branch 31 via the third branch 40 and the first branch 50.
Similarly, when the first branch 50 is rotated to the second position, the second branch 51 is rotated to the fourth position. At this time, the first branch 50 is butted against the first end of the second discontinuity 410 and extends toward the first branch 30; the second branch 51 is butted with the second end of the first fracture 310 and extends towards the third branch 40; one row of wheels of the double row of running wheels is moved to the fourth branch 41 via the first branch 30 and the first fork 50, and the other row of wheels is moved to the third branch 40 via the second fork 51 and the second fork 51.
It will be understood that the travel fork 5 can also be in any other form, as long as it allows the switching of the travel wheels, which is not further described herein.
It should be noted that the junction between the fork 5 and the second branch 31 and the fourth branch 41 must be in communication in order to allow the running wheels to move from the fork 5 to the second branch 31 or the fourth branch 41.
The track device may further comprise a first drive assembly 6, a second drive assembly 7, a third drive assembly 8 and a fourth drive assembly 9, wherein:

The first drive assembly 6 and the second drive assembly 7 may be disposed below the first fork 50 and away from the road wheels. It should be noted that the first driving assembly 6 and the second driving assembly 7 may be a set of driving devices, and can also drive the first branch 50 and the second branch 51 to rotate.
Similarly, the third driving assembly 8 and the fourth driving assembly 9 are used as power parts, and may be motors or pneumatic motors, etc., and are not limited herein.
