Each of the first and

second fixing rails

111 and 112 extends in a first direction, and the first and

second fixing rails

111 and 112 are spaced apart in a second direction, wherein the first direction is perpendicular to the second direction.

Each of the third and

fourth fixing rails

113 and 114 extends in the second direction, and the third and

fourth fixing rails

113 and 114 are spaced apart in the first direction. The third fixing rail 113 is connected to each of the first and

second fixing rails

111 and 112, and the fourth fixing rail 114 is connected to each of the first and

second fixing rails

111 and 112. The first to fourth fixing rails 111 to 114 constitute a first annular fixing rail 141.

The moving rail 120 extends in the second direction, and the moving rail 120 is movably provided on each of the first and second fixed

rails

111 and 112 in the first direction. The moving rail 120 is located between the third and fourth fixed

rails

113 and 114 in the first direction. Wherein the first direction is shown by arrow F in fig. 1, and the second direction is shown by arrow G in fig. 1.

A process of conveying a material (e.g., a cassette) by the crown block system 1 including the rail device 10 according to the embodiment of the present invention, that is, a process of conveying the material from the second material port to the first material port by the trolley 20, will be described below with reference to fig. 1 to 4.

As shown in fig. 1, a material opening one 30 a-a material opening twelve 30b may be disposed on the outer side of the first annular fixed rail 141, and a position one 40 a-a position twelve 40b on the first annular fixed rail 141 are respectively opposite to the material opening one 30 a-the material opening twelve 30 b. For example, a first position 40a of the first endless fixed track 141 is opposite to the first material opening 30a, and when the trolley 20 is located at the first position 40a, the material on the trolley 20 can be carried to the first material opening 30a and the material at the first material opening 30a can be carried to the trolley 20. The dolly 20 can move on the first endless fixed track 141 in a clockwise direction or a counterclockwise direction. For convenience of description, the dolly 20 is set to move on the first endless fixed rail 141 in the counterclockwise direction.

When the second material port is located upstream of the first material port, for example, the second material port may be a material port seven 30c, and the first material port may be a material port eight 30d, the material may be conveyed from the second material port to the first material port according to the existing material conveying manner. That is, the cart 20 is moved to the seventh position 40c on the first endless fixed rail 141, the material of the second material port is carried to the cart 20, the cart 20 is moved to the eighth position 40d on the first endless fixed rail 141, and the material of the cart 20 is carried to the first material port.

Where pick-and-place devices for handling material between the trolley 20 and the material port may be known and may be mounted in a known manner. The structure and mounting of the pick-and-place device are not relevant to the inventive aspects of the present application and will therefore not be described in detail.

For convenience of description, a first position on the first annular fixed rail 141 is set to be opposite to the first material port, and a second position on the first annular fixed rail 141 is set to be opposite to the second material port. The second material opening is positioned at the upstream of the first material opening, and the second material opening is positioned at the upstream of the first material opening: the distance traveled by the carriage 20 from the second position to the first position is less than the distance traveled by the carriage 20 from the first position to the second position. The second material opening is positioned at the downstream of the first material opening, and the second material opening is positioned at the downstream of the first material opening: the distance traveled by the carriage 20 from the second position to the first position is greater than the distance traveled by the carriage 20 from the first position to the second position.

When the first material port is located at the upstream of the second material port (i.e. the second material port is located at the downstream of the first material port), the material is conveyed from the second material port to the first material port. For convenience of description, the material conveying method of the crown block system 1 will be described below by taking the second material port as the material port eight 30d and the first material port as the material port seven 30c as examples. The material conveying method comprises the following steps:

A) the cart 20 is moved to a position on the first endless fixed rail 141 opposite to the second material port, that is, a position eight 40d, and the material of the second material port is carried to the cart 20.

B) The moving rail 120 is moved to a first position on the first endless fixed rail 141 adjacent to the second material port, the first position being located downstream of the second material port, as shown in fig. 2. That is, the first position is adjacent to and downstream of the position opposite to the second material port on the first endless fixed rail 141.

Specifically, when the second material opening is adjacent to the first fixed rail 111, the first position may be a position of the movable rail 120 on the first fixed rail 111, and when the second material opening is adjacent to the second fixed rail 112, the first position may be a position of the movable rail 120 on the second fixed rail 112. For example, the first position may be position H in fig. 2.

C) The dolly 20 is moved onto the moving rail 120. For example, the trolley 20 may move to position I on the moving rail 120.

D) The moving rail 120 is moved to a second position on the first endless fixed rail 141 adjacent to the first material port, the second position being upstream of the first material port, as shown in fig. 3. That is, the second position is adjacent to and upstream of the position on the first endless fixed track 141 opposite to the first material port.

Specifically, when the first material port is adjacent to the first fixed rail 111, the second position may be a position of the moving rail 120 on the first fixed rail 111, and when the first material port is adjacent to the second fixed rail 112, the second position may be a position of the moving rail 120 on the second fixed rail 112. For example, the second position may be position J in fig. 3.

E) The cart 20 is moved to a position opposite to the first material port on the first endless fixed rail 141, that is, a position seven 40c, and the material on the cart 20 is carried to the first material port, as shown in fig. 4.

Wherein, the step A) and the step B) are carried out in no sequence. Step a) may be performed first and then step B) may be performed first), step B) may be performed first and then step a) may be performed, or step a) and step B) may be performed simultaneously.

When the first trolley 20a is down on one of the first fixed track 111 and the second fixed track 112, the material conveying method of the overhead travelling crane system 1 includes the following steps:

A) the moving rail 120 is moved to a third position on the first endless fixed rail 141, which is located upstream of the first carriage 20 a. For example, the third location may be adjacent the first trolley 20 a.

B) The second carriage 20b is moved onto the moving rail 120.

C) The moving rail 120 is moved to a fourth position on the first endless fixed rail 141, which is located downstream of the first carriage 20 a. For example, the fourth location may be adjacent the first trolley 20 a.

D) The second carriage 20b is moved onto the first endless fixed rail 141. Whereby the second trolley 20b can be caused to pass over the location on the first endless fixed track 141 where the breakdown occurred and then the second trolley 20b can be moved to the destination location.

As shown in fig. 1, when the first trolley 20a is down on one of the third fixed track 113 and the fourth fixed track 114, the material conveying method of the overhead travelling crane system 1 includes the following steps: the moving rail 120 is moved to a position on the first endless fixed rail 141 adjacent to the one of the third and fourth

fixed rails

113 and 114 to replace the one of the third and fourth

fixed rails

113 and 114 with the moving rail 120.

Accordingly, when the trolley 20 is crashed on both the third fixed track 113 and the fourth fixed track 114, the two moving tracks 120 may be used to replace the third fixed track 113 and the fourth fixed track 114, respectively.

The rail device 10 according to the embodiment of the present invention can transport the trolley 20 by using the moving rail 120 when transporting the material from the downstream material port to the upstream material port by providing the moving rail 120 moving in the first direction on the first fixed rail 111 and the second fixed rail 112, thereby greatly shortening the moving trajectory of the trolley 20 and the time consumption for transporting the material so as to greatly improve the efficiency of transporting the material by the crown block system 1.

Moreover, when a breakdown occurs on the first circular fixed track 141 of the overhead traveling crane system 1, the traveling track 120 may be used to transport the trolleys 20 so that the trolleys 20 cross the location where the breakdown occurs, and the traveling track 120 may be used to replace the fixed track where the breakdown occurs, so that the trolleys 20 on the overhead traveling crane system 1 may be prevented from being jammed, and the overhead traveling crane system 1 may be prevented from stopping.

Therefore, by using the rail device 10 according to the embodiment of the present invention, not only the moving trajectory of the trolley 20 and the time consumed for conveying the material can be greatly reduced, so as to greatly improve the efficiency of the overhead traveling crane system 1 in conveying the material, but also the trolley 20 on the overhead traveling crane system 1 can be prevented from being jammed, and the overhead traveling crane system 1 can be prevented from stopping running.

The invention also provides an overhead travelling crane system 1. The overhead traveling crane system 1 according to the embodiment of the present invention includes a rail device and at least one trolley 20. The track set is a track set 10 according to the above described embodiment of the present invention. Wherein the trolley 20 is movably arranged on the rail device 10.

A-2) moving the cart 20 onto the moving rail 120.

A-3) moving the moving rail 120 to a fourth position on the first endless fixed rail 141 adjacent to the second material port, which may be upstream of the second material port. That is, the fourth position is adjacent to and upstream of the position opposite to the second material port on the first endless fixed rail 141.

A-4) moving the cart 20 to a position opposite to the second material port on the first endless fixed rail 141, and carrying the material of the second material port to the cart 20.

As shown in fig. 1, in some embodiments of the present invention, the overhead traveling crane system 1 may include a rail device 10 and a plurality of dollies 20 movably provided on the rail device 10.

The rail device 10 may include a first fixed rail 111, a second fixed rail 112, a third fixed rail 113, a fourth fixed rail 114, and a moving rail 120.

In one embodiment of the present invention, as shown in fig. 1, the track set 10 may further include a first rail 131 and a second rail 132. Each of the first and

second guide rails

131 and 132 may extend in the first direction, the first guide rail 131 may be provided on the first fixed rail 111, and the second guide rail 132 may be provided on the second fixed rail 112. The moving rail 120 may be movably provided on each of the first and

Preferably, a first end of the moving rail 120 may be movably provided on the first guide rail 131 in the first direction, and a second end of the moving rail 120 may be movably provided on the second guide rail 132 in the first direction. This makes the construction of the rail device 10 more rational.

As shown in fig. 1, in one example of the present invention, the rail device 10 of the overhead traveling crane system 1 may further include a fifth fixing rail 115 and a sixth fixing rail 116.

The fifth fixing rail 115 may extend in the second direction, the fifth fixing rail 115 may be connected to each of the first and second fixing rails 111 and 112, and the fifth fixing rail 115 may be located between the third and fourth fixing rails 113 and 114 in the first direction.

At least one moving rail 120 may be disposed between the third fixed rail 113 and the fifth fixed rail 115, and at least one moving rail 120 may be disposed between the fourth fixed rail 114 and the sixth fixed rail 116.

fixed rails

114 and 116 in the first direction.

By providing the fifth fixing rail 115 and the sixth fixing rail 116, it is possible to make the rail apparatus 10 have not only the first annular fixing rail 141 having a larger circumference but also the second annular fixing rail 142 and the third annular fixing rail 143 having a smaller circumference. Therefore, a more reasonable conveying path can be selected according to the position relationship between the first material port and the second material port (namely the material port for outputting materials and the material port for receiving materials), so that the moving track of the trolley 20 is shortened, the time consumed for conveying materials is shortened, and the efficiency of conveying materials by the overhead travelling crane system 1 is improved.

fixed rails

113, 114, 115, 116 may be perpendicular to the first fixed rail 111, and the moving rail 120 may be perpendicular to the first fixed rail 111. This makes the construction of the rail device 10 more rational.

Preferably, as shown in fig. 1, a first end of each of the third, fourth, fifth, sixth and moving

rails

113, 114, 115, 116 and 120 may be connected to the first fixed rail 111 through a first arc-shaped rail, and a second end of each of the third, fourth, fifth, sixth and moving
