TECHNICAL FIELD OF THE INVENTION
The present invention relates to a trolley-type transporter that is used in a ski resort, a steep slope, a factory, or the like, and travels along rails by, for example, a lift vehicle being supplied with power from a trolley. The present invention relates to a trolley-type transport machine that is prevented from being short-circuited.
[0002]
[Prior art]
The trolley-type transporter has a vehicle running along a rail, provided with a current collecting unit having a current collector attached thereto, and a trolley to which the current collector is joined is attached to the rail. Japanese Patent Application Laid-Open No. 8-295232 discloses a lift vehicle used for a suspension-type trolley-type transporter in which a vehicle is suspended by rails and travels, and this will be described with reference to FIGS. The lift vehicle S is hung not on a straight rope but on a horizontal H-shaped rail 1. By curving the rail 1, the lift vehicle S can travel not only in a curved manner but also in a lift vehicle S. It is characterized in that it can run and stop every time.
[0003]
The H-shaped rail 1 is laid such that the flange 1a is horizontal, a rack 2 is fixed to the center line of the bottom surface of the flange 1a, and a trolley 3 is provided adjacent to the rail 1. The trolley 3 includes a plurality of power supply lines 3a, a position transmission line 3b for transmitting position information of the front lift vehicle S to the rear lift vehicle S, and position detection for detecting whether the lift vehicle S exists in the front. Each of the power supply lines 3a, the position transmission line 3b, and the position detection line 3c are arranged in parallel, and are integrated into a band by an insulator. However, one side of the trolley 3 is exposed so that the current collector 4 is joined. Further, the number of the trolleys 3 is not limited to five as shown, and is not specified such as two or four or more.
[0004]
Such a trolley 3 is attached to a large number of brackets 5 projecting from one side of the rail 1 at predetermined intervals. However, since an AC voltage of 220 to 440 V is constantly applied to the power supply line 3a, and it is dangerous if the AC power supply line 3a is exposed, a U-shaped duct 6 is opened downward between the brackets 5. The trolley 3 is accommodated in the duct 6 so that the trolley 3 is not directly exposed to the wind and the rain. The opening 6a is provided below the duct 6, so that the current collector 4 can move through the opening 6a.
[0005]
On the other hand, the lift vehicle S is provided with a traveling device 10 that travels along the rail 1, a riding section 11 suspended by the traveling device 10, and the like. In the traveling device 10, a pinion 13 meshing with the rack 2, a motor 14 for driving the pinion 13, an upper roller 15 and a lower roller 16 sandwiching a flange 1a of the rail 1 from above and below, and a center of the rail 1 are provided in a frame 12. A side roller 17 sandwiching the portion 1b from both sides, a brake means 18 for stopping the traveling device 10 and the like are provided. A control box 19 for controlling the motor 14 and the brake means 18 is provided near the riding section 11. Further, a connecting member 7 protrudes from an upper portion of the traveling device 10, and five current collectors 4 are fixed to the connecting member 7 in the drawing. A lead wire (not shown) is led out from the current collector 4, and the lead wire is connected to the control box 19.
[0006]
When the motor 14 is driven, the pinion 13 rotates, and the lift vehicle S travels along the rail 1. At this time, since the upper roller 15, the lower roller 16, and the side roller 17 sandwich the rail 1, the lift vehicle S runs without coming off the rail 1. Further, when a current flows from the front lift vehicle S to the position transmission line 3b, and the lift vehicle S traveling behind senses the current, the brake means 18 is activated and the motor 14 is stopped, so that the lift The vehicles S do not collide with each other.
[0007]
[Problems to be solved by the invention]
By the way, the trolley 3 has an opening 6a on the lower side so that the current collector 4 can move while being joined to the trolley 3 while preventing the trolley 3 from being directly exposed to the weather and the snow. It is housed in a downward U-shaped duct 6.
[0008]
However, since the opening 6a is provided on the lower side of the duct 6, dust, raindrops, or snow enters the duct 6 from the opening 6a, particularly under a strong wind, heavy rain, or a snowstorm, and these enter the trolley 3. Accumulation may cause a short circuit. Then, electric current does not flow through the trolley 3 and the lift vehicle S cannot run, or safe running becomes difficult.
[0009]
Therefore, an object of the present invention is to provide a trolley-type transport device in which dust, raindrops, snow, and the like do not enter the duct without restricting the movement of the current collector.
[0010]
[Means for Solving the Problems]
The trolley-type transporter of the present invention is a trolley-type transporter in which a vehicle traveling along a rail is provided with a current collecting unit having a current collector attached thereto, and a trolley to which the current collector is joined is attached to the rail. A trolley is housed inside, and a duct provided with an opening through which a part of the current collecting unit is provided on the lower side, and the opening of the duct is closed so that the part of the current collecting unit can be moved while being sandwiched. And a deformable flexible closure band.
[0011]
According to this trolley-type transporter, the flexible closing band closes the opening of the duct in which the trolley is housed, so that dust, raindrops or snow does not enter the duct, and the trolley has dust, raindrops or the like. Snow and the like can be prevented from accumulating. In addition, since the closed band is flexible and deforms so as to sandwich the current collecting unit, the current collector attached to the current collecting unit is joined to the trolley, and a part of the current collecting unit is sandwiched by the closed band. While traveling through the opening.
[0012]
The duct has a main body portion formed in a downward U-shape including an upper surface portion and a pair of side surface portions protruding downward from both sides of the upper surface portion, and a diagonal direction from each of the side surface portions toward a center below the main body portion. And a pair of inclined portions whose edges face each other with a wider interval than the current collecting unit, and the closed band is a pair of band-shaped plates, It is preferable that an upper end portion is fixed to the inclined portion, and inner surfaces of the lower end portions are joined to each other.
[0013]
When the upper end is fixed to each inclined portion of the duct, each lower end is inclined downward toward the center of the duct, and the flexible, band-shaped closing band used in a pair is used. By joining the inner surfaces, the opening of the duct is closed. Since the closure band is flexible, the end of the closure band is bent at the portion without the current collection unit to close the opening of the duct by joining, and the portion of the current collection unit at the portion with the current collection unit The opening is closed by bending to sandwich the opening. Since a part of the current collecting unit can be advanced while being sandwiched by the closed band, the state where the opening of the duct is closed is maintained even when the current collecting unit is advanced.
[0014]
A heater may be housed in the duct. If this trolley-type transport machine is installed in a cold region, the trolley and the current collector may freeze, but the heater inside the duct will prevent the trolley from being closed by a heater. The trolley and the current collector are not frozen, and smooth running can be ensured.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
A trolley-type transporter according to an embodiment of the present invention will be described with reference to FIGS. The same parts as those in the related art will be described with the same reference numerals.
[0016]
As shown in FIG. 1, the trolley-type transporter according to the present embodiment has a lift vehicle S suspended from a horizontal H-shaped rail 1, and a trolley 3 attached to the rail 1 is placed in a downward U-shaped duct 20. The current collector unit 40 that is housed and the lower opening 21 c of the duct 20 is closed by a flexible closing band 30, and a part of the current collecting unit 40 to which the current collector 4 joined to the trolley 3 is attached It is characterized by being able to proceed through the opening 21c while being sandwiched.
[0017]
The rail 1 is fixed to the lower side of each beam member 9 that protrudes in the horizontal direction from the upper part of the plurality of columns 8. The duct 20 is fixed to the lower side of each bracket 5 which protrudes at a predetermined interval on one side of the rail 1.
[0018]
As shown in FIG. 2, the duct 20 includes a downwardly U-shaped main body 21 and a pair of inclined portions 22. The main body portion 21 includes an upper surface portion 21a fixed to the bracket 5 and a pair of side surface portions 21b protruding downward from both sides of the upper surface portion 21a, and a lower side between both side surface portions 21b is an opening 21c. ing. However, when the bracket 5 is provided continuously along the duct 20, the upper surface portion 21a also serves as the lower surface of the bracket 5, and the lower surface of the bracket 5 and the side surface portions 21b constitute the main body portion 21 of the duct 20. Can be.
[0019]
On the other hand, the inclined portion 22 is bent in a rectangular shape, the base end portion 22a is fixed to the side surface portion 21b of the main body portion 21 with a bolt 23, and the distal end portion 22b protrudes below the center of the main body portion 21 to form a pair of inclined portions. A predetermined interval is provided between the edges 22c of the portion 22. The main body portion 21 and the inclined portion 22 may be integrated by a bolt 23, may be integrated by welding, or may be formed by integrally forming both.
[0020]
In any case, the upper end portion 31 of the flexible closing band 30 is fixed to the distal end portions 22b of the pair of inclined portions 22 with the bolts 23. The closing band 30 is a flexible band-like plate made of rubber or elastic resin such as vinyl or nylon, and is used as a pair. When each upper end portion 31 of the closed band 30 is fixed to each inclined portion 22 of the duct 20, the lower end portion 32 of the closed band 30 is inclined downward toward the center of the duct 20, and the inner surfaces of the lower end portions 32 are joined to each other. Thus, the opening 21c of the duct 20 is closed. Since the closing band 30 is flexible, the lower end portion 32 is bent and joined at a portion where the current collecting unit 40 is not provided, thereby closing the opening 21 c of the duct 20, and at a portion where the current collecting unit 40 is provided. The opening 21c is closed by bending so as to sandwich a part of the opening 40c.
[0021]
The trolley 3 is fixed inside the upper surface portion 21a of the duct 20 in which the opening 21c is closed by the closing band 30. The trolley 3 is composed of a power supply line 3a, a position transmission line 3b, and a position detection line 3c as described in the related art, and is integrated in a band shape by an insulator, and is not joined to the upper surface portion 21a of the duct 20. The side is not coated with an insulator so that the current collectors 4 are joined. The width of the upper surface portion 21a of the duct 20 is wider than the width of the trolleys 3 arranged in parallel, and the interval provided between the ends 22c of the pair of inclined portions 22 is substantially equal to the width of the trolleys 3 arranged in parallel. I have.
[0022]
The current collector 4 is attached to the upper end of the current collecting unit 40 as shown in FIGS. In the current collecting unit 40, an upward U-shaped holder 42 is fixed to the upper end of a rod 41 that moves in a vertical posture, and the same number of fixing portions 43 as the trolley 3 are sandwiched in the holder 42. An arm 44 protrudes in the front-rear direction, and a movable part 45 is attached to the tip of the arm 44. The current collector 4 is swingably attached to the upper part of the movable part 45. For example, when the number of the trolleys 3 is five as shown in the figure, five fixing portions 43 are fixed to the holder 42, and a pair of two arms 44 project to be able to swing forward and backward of the total of 20 fixing portions 43, A total of ten movable parts 45 are attached to a pair of arms 44, and a total of ten current collectors 4 are attached to each movable part 45.
[0023]
When the arm 44 swings, the current collector 4 is joined to the trolley 3 even if the trolley 3 is laid not only in the horizontal direction but also in the inclined direction. The arm 44 is provided with a spring (not shown) for urging the current collector 4 against the trolley 3 to securely join the trolley 3.
[0024]
A lead wire 46 is connected to the current collector 4 from below. The lead wire 46 is connected to the head or tail of the movable part 45 so that the movable part 45 can easily swing. The lead wire 46 is led out along the rod 41 to a lower portion of the rod 41. The lead 46 is surrounded by a cover 47 to prevent the lead 46 from rubbing against the closure band 30. Alternatively, a groove (not shown) may be provided in the rod 41, and the lead wire 46 may be embedded in the groove.
[0025]
As shown in FIG. 1, the lower end of the rod 41 is fixed to a connecting member 9 that protrudes in the lateral direction of the frame 12 of the traveling device 10 installed above the lift vehicle S. The traveling device 10 includes a pinion 13 meshing with the rack 2 fixed to the bottom surface of the flange 1a of the rail 1, a motor 14 for driving the pinion 13 (see FIG. 5), and a flange 1a of the rail 1 as in the prior art.

As shown in FIG. 2, for example, the heater 50 is preferably a hot wire heater 50 that is wired inside the upper surface 21 a of the duct 20 and on the side of the trolley 3. Alternatively, the hot-wire heater 50 can be wired inside one or both side surfaces 21 b of the duct 20. Further, the heaters 50 may be arranged in points within the duct 20 at appropriate intervals, and may branch and heat an electric wire (not shown) from the power supply line 3a. In any case, when the opening 21c of the duct 20 is closed by the closing plate 30, the heater 50 warms the inside of the duct 20, and the trolley 3 and the current collector 4 can be prevented from freezing.
[0027]
In addition, when a current flows from the front lift vehicle S to the position transmission line 3b, and the lift vehicle S traveling behind senses the current, the brake means 18 is operated and the motor 14 is stopped, so that the lift The configuration in which the vehicles S are prevented from colliding with each other is the same as in the related art. Also in the trolley-type transporting machine of the present invention, a current is supplied from the power supply line 3a to the control box 19, and the motor 14 is driven to rotate the pinion 13 so that the traveling device 10 travels along the rail 1. I do.
[0028]
In the trolley-type transporter, the inner surfaces of the lower end portions 32 of the pair of closed bands 30 are joined to each other at a portion of the current collecting unit 40 without the rod 41, thereby forming the opening 21c of the duct 20. At a certain portion of the rod 41, the pair of closing bands 30 bends so as to sandwich the rod 41, thereby closing the opening 21 c of the duct 20. Thus, the opening 21c of the duct 20 is closed by the closing band 30 over the entire length.
[0029]
Therefore, dust, raindrops, snow, and the like can be prevented from entering the duct 20. Further, since the closing band 30 is flexible, the current collector 4 attached to the upper end of the rod 41 is joined to the trolley 3 while the rod 41 attached to the traveling device 10 pushes the closing band 30 apart. And the lift vehicle S can travel safely.
[0030]
The present invention can be variously modified within the scope of the technical matters described in the claims without being limited to the embodiments of the present invention. For example, if the trolley 3 is laid in the vicinity of the rail 1 and the trolley 3 is accommodated in the downward U-shaped duct 20, only the suspension type as described above However, even if the vehicle is of a straddle type in which the vehicle runs on a rail, or a case where luggage is put on a person other than a person, the present invention can be implemented in a similar manner including the modified examples described later.
[0031]
The current collecting unit 40 sandwiched between the closed bands 30 is not limited to the rod 41. Further, the closing band 30 may be a brush that is densely planted, and may be provided on the entire length of the duct 20 so that the brush closes the opening 21 c of the duct 20. Further, the duct 20 has only the main body 21 without the inclined portion 22, and the upper end 31 of the closing band 30 is directly fixed to the side surface 21 b so that the inner surfaces of the lower end 32 of the closing band 30 are joined to each other. You can also.
[0032]
Further, the trolley 3 may be vertically fixed to the side surface 21b of the downward U-shaped duct 20, or may be housed separately from the upper surface 21a and the side surface 21b of the duct 20.
[0033]
【The invention's effect】
