DETAILED DESCRIPTION OF EMBODIMENTS In this embodiment, illustrated is a lifting device of an overhead monorail hoist, comprising a lift cage and at least one group of lift wheels; the lift cage is provided with an accommodation groove for accommodating the lift wheels; a first hanging frame is provided on a first side wall of the accommodation groove, and a second hanging frame is provided on a second side wall, opposite to the first side wall, of the accommodation groove; a first lift wheel of the at least one group of the lift wheels is rotatably arranged on an end of the first hanging frame away from the first side wall, and a second lift wheel of the at least one group of the lift wheels is rotatably arranged on an end of the second hanging frame away from the second side wall; a first gap is formed between the first lift wheel and the second lift wheel; a monorail comprises at least a first runway on which the first lift wheel is arranged and a second runway on
4
17424017_1 (GHMatters) P113263.AU which the second lift wheel is arranged; a separator is arranged between the first runway and the second runway; and the first gap at least accommodates the separator. The principle of the present invention is described as follows. The two lift wheels are directly placed on the monorail, and outer circular surfaces of the lift wheels are pressed against the monorail through the gravity of the overhead hoist, so that the lift wheels can roll by friction, and additional power devices are eliminated. Thus, the lifting device of the overhead monorail hoist of this embodiment has a simple structure and high efficiency. In some embodiments, guide faces of the first and second runways each are a slope with a higher side at a side of the separator; the lift wheel is cylindrical, and an upper end of the lift wheel is inclined outward by a preset angle, so that an outer circular surface of the lift wheel engages with the slope. In this way, all points on the outer circular surface of the lift wheel are guaranteed to have the same linear velocity, so that the lift wheel has a longer service life. The guide faces of the first and second runways each are a slope with a higher side at a side of the separator, i.e., each of the guide faces of the monorail has a certain slope to reduce the swing of the overhead monorail hoist in the horizontal direction, because the lift wheels are required to overcome resistance from the slopes when the overhead monorail hoist swings in the horizontal direction. In some embodiments, the lift cage is further provided with a blocking wheel for limiting the lifting device relative to the first runway or the second runway; one end of the blocking wheel is fixed to the lift cage, and an outer circular surface of the blocking wheel rotatably fits the separator. In this way, the lift cage is avoided to incline in a vertical direction, and the lift wheels are ensured to well contact with the runways. This embodiment further provides an overhead monorail hoist, comprising at least two lifting devices of the above-mentioned lifting devices, a car fixed under the two lifting devices and a control device for controlling a movement of the two lifting devices; at least one lifting device of the at least two lifting devices is provided with at
5
17424017_1 (GHMatters) P113263.AU least one drive element which is connected to the lift cage; and the control device is fixed under the lifting device. Since the lifting devices are connected with each other, the whole overhead monorail hoist can be pushed or pulled to move when the lifting devices are only provided with one drive element. Obviously, the drive element can be provided at each of the lifting devices to enable the power to be more stronger. In some embodiments, a drive component is provided in the lift cage in which the drive element is arranged; one end of the drive component is connected to the lift wheel, and the other end of the drive component passes throguh the lift cage and is connected to the drive element; the drive component comprises a driving gear and a driven gear; the driving gear is connected to an output end of the drive element, and the driven gear is connected to an axle of the lift wheel. Generally, teeth of the driving gear is less than that of the driven gear, so that the drive element drives the lift wheel through a reduction transmission, and the lift wheel obtains a larger torque. In some embodiments, the monorail is an I-shaped guide rail; an upper surface of one side of a bottom plate of the I-shaped guide rail forms the first runway, and an upper surface of the other side of the bottom plate of the I-shaped guide rail forms the second runway. The guide face of the I-shaped guide rail is generally a slope with a higher position in the middle, so that the overhead monorail hoist is reduced to swing in the horizontal direction. In some embodiments, the I-shaped guide rail consists of a plurality of I-shaped section bars connected end-to-end; a lug is provided at a top end of each of the I-shaped section bars, and a fastener is provided at a bottom of each of the I-shaped section bars for connecting the I-shaped section bars. In this way, the guide rail with a sufficient length is formed by connecting multiple I-shaped section bars. In some embodiments, the lifting device further comprises a drive gear to increase their power for travelling on a slope; the drive gear is arranged outside the lift wheels, and the drive gear and the lift wheel are arranged at the same axle. The monorail is further provided with a rack which engages with the drive gear and arranged at an outer side of the I-shaped guide rail. In this manner, when the overhead
6
17424017_1 (GHMatters) P113263.AU monorail hoist goes up, the gradeability of the overhead monorail hoist is enhanced through the engagement of the drive gear and the rack, and the downward inertia of the overhead monorail hoist is reduced when the overhead monorail hoist goes down to make the overhead monorail hoist safer.
In some embodiments, the overhead monorail hoist further comprises a hoist
beam. Two ends of the hoist beam are respectively fixed under the two lifting devices,
and the car is fixed under the two lifting devices via the hoist beam, such that the car
is well fixed. In some embodiments, the drive element is an electric motor, and an output shaft
of the electric motor is connected to the driving gear; the overhead monorail hoist
further comprises a power unit for supplying power to the drive element and the
control device, and the power unit is electrically connected to the drive element and
the control device. Specifically, the electric motor may be a permanent magnet motor.
Compared with electric excitation motors, the permanent magnet motor, especially a
rare earth permanent magnet motor, has the characteristics of a simple structure,
reliable operation, small size, light weight, small loss, and high efficiency.
The present invention will be further described as follows with reference to the
accompanying drawings and embodiments. It should be noted that the embodiments
described herein are only illustrative, and are not intended to limit the scope of the
present invention.
It should be noted that unless specified, the term "connect" should be understood
broadly. For example, the elements may be connected electrically; or directly
connected or indirectly connected through an intermediate medium. Alternatively, two
elements may be in communication or interact with each other. For the skilled in the
art, the specific meanings of the above terms in the present invention can be
understood according to specific conditions.
In addition, terms "first", "second" and "third" in the present invention are used
for description only, and are not intended to indicate or imply their relative
importance. It should be understood that "first", "second" and "third" can be changed,
7 17424017_1 (GHMatters) P113263.AU which explicitly or implicitly indicates that one or more features defined by "first" or
"second" may be included in the present invention. In addition, the technical solutions
of various embodiments may be combined to form other embodiments which are
considered to fall within the scope of the appended claims.
FIG. 1 is a schematic diagram of a lifting device of an overhead monorail hoist
according to a first embodiment of the present invention; and FIG. 2 is a top view of
the lifting device in FIG. 1. As shown in FIGS. 1-2, this embodiment provides a
lifting device of an overhead monorail hoist, comprising a lift cage 17 and a lift wheel
14. A middle of the lift cage 17 is provided with an accommodation groove which
opens upwards, and at least one lift wheel 14 is respectively installed on two inner
side walls of the accommodation groove which are oppositely arranged.
In this embodiment, the lift wheel 14 is installed in the following direction. The
outer circular surface of the lift wheel 14 is pressed against the monorail 2 through the
gravity of the overhead monorail hoist, so that the lift wheel can roll by friction, and
additional power devices are eliminated.
In this embodiment, the lift wheel 14 which may be cylindrical inclines
outwardly by a preset angle, so that the outer circular surface of the lift wheel 14
engages with the monorail 2. In this way, all points on the outer circular surface of the
lift wheel are guaranteed to have the same linear velocity, so that the lift wheel 14 has
a longer service life. The lift wheel 14 is set to incline outwardly by a preset angle, so
that the outer circular surfaces of the lift wheel 14 engages with the monorail, because
a bottom surface of an inner cavity of the monorail 2, i.e., the guide surface, has a
certain slope which can avoid that the lift wheel swings in the horizontal direction.
In some embodiments, four lift wheels 14 are installed in the accommodation
groove of the lift cage 17, where two sides of the accommodation groove each are
arranged with two lift wheels, such that the overhead monorail hoist moves steadily
and has a simple structure.
In some embodiments, the lift cage 17 is further provided with a blocking wheel
16 for limiting the lifting device relative to the monorail 2. When the lifting device of
8
17424017_1(GH Mtters) P113263.AU the overhead monorail hoist moves, especially when it turns, the lifting device may incline to both sides. As a result, the overhead monorail hoist moves unsteadily since the lift wheel 14 and the monorail 2 contact in line but not in surface, and moreover, the lift wheel 14 is easy to be damaged. However, when the lifting device inclines, the outer circular surface of the blocking wheel 16 abuts against the monorail 2 to avoid further inclinations of the lifting device. The blocking wheel 16 is fixed to the lift cage 17 via a mounting arm 15. One end of the mounting arm 15 is fixed to the lift cage 17 via screws, and the other end of the mounting arm is mounted with the blocking wheel 16.
This embodiment further provides an overhead monorail hoist. FIG. 3 is a
schematic diagram of the overhead monorail hoist according to a second embodiment
of the present invention. With reference to FIGS. 1-3, the overhead monorail hoist
comprises the lifting devices of the overhead monorail hoist in the first embodiment, a
car 19 fixed under the two lifting devices and a control device 21 for controlling the
movement of the lifting devices; at least one lifting device of the at least two lifting
devices is provided with at least one drive element 7 which is connected to the lift
cage 17; and the control device 21 is fixed under the lifting devices. Since the lifting
devices are connected with each other, the whole overhead monorail hoist can be
pushed or pulled to move when the lifting devices are only provided with one drive
element 7. Obviously, each of the lifting devices can be provided with the drive
element to enable the power to be more stronger.
As shown is FIG. 2, in this embodiment, a drive component is provided in the lift
cage 17; one end of the drive component is connected to the lift wheel, and the other
end of the drive component passes through the lift cage 17 and is connected to the
drive element 7; the drive component comprises a driving gear 10 and a driven gear 9;
the driving gear 10 is connected to an output end of the drive element 7, and the
driven gear 9 is connected to an axle 11 of the lift wheel 14. In this embodiment, teeth
of the driving gear 10 are less than that of the driven gear 9, so that the drive element
7 drives the lift wheel 14 through a reduction transmission, and the lift wheel 14
9 17424017_1 (GHMatters) P113263.AU obtains a larger torque. The axle 11 is further provided with a rolling bearing 12, and an outer ring of the rolling bearing 12 is fixed in a bearing chamber of the lift cage 17.
For clarity, the bearing chamber of the lift cage 17 and how the rolling bearing 12 is
installed in the bearing chamber are not shown in FIG. 2.
Two sides of the lift cage 17 each are provided with two lift wheels, i.e., two
inner side walls of the accommodation groove which are oppositely arranged each are
mounted with two lift wheels 14. Correspondingly, two driven gears 9 are provided,
i.e., the drive component may comprise a driving gear 10 and two driven gear 9, so
that the power transmission is more balanced.
FIG. 4 is a perspective view of the I-shaped guide rail of the overhead monorail
hoist according to the second embodiment of the present invention. FIG. 5 is a side
view of the I-shaped guide rail in FIG. 4. As shown in FIGS. 4-5, the I-shaped guide
rail consists of a plurality of I-shaped section bars connected end-to-end; lugs are
provided at a top end of each of the I-shaped section bars, and a fastener is provided at
a bottom of each of the I-shaped section bars for connecting the I-shaped section bars.
The lug is fixed at a top wall of a mine tunnel, and the fastener is configured to
connect the I-shaped section bars end- to-end to enable the I-shaped guide rail to be a
whole structure.
In this embodiment, the lugs are configured to connect the I-shaped section bars
end-to-end. As shown in FIGS. 4-5, one end of the I-shaped section bar is provided
with a first lug 1, and the other end of the I-shaped section bar is provided with a
second lug 4. The first lug 1 is located at a first side of the I-shaped section bar in a
width direction, and the second lug 4 is located at a second side of the I-shaped
section bar in a width direction. The first lug 1 and the second lug 4 both extend
outwardly along a length direction of the I-shaped section bar. Thus, the first lug 1
and the second lug 4 are fixed with each other when the I-shaped section bars connect
with each other.
In this embodiment, the fastener comprises a pin 5 and a fastening structure 6.
When the I-shaped section bars are connected with each other, the pin 5 is inserted
10
17424017_1 (GHMatters) P113263.AU into the fastening structure 6.
In this embodiment, the lifting device further comprises a driving gear 13 to
increase their power for travelling on a slope; the drive gear 13 is arranged outside the
lift wheel 14, and the drive gear and the lift wheel are arranged at the same axle. The
monorail is further provided with a rack which engages with the drive gear and is
arranged at an outer side of the I-shaped guide rail, i.e., the drive gear 13 and the rack
have the same modulus. In this manner, when the overhead monorail hoist goes up,
the gradeability of the overhead monorail hoist is enhanced through the engagement
of the drive gear and the rack, and the downward inertia of the overhead monorail
hoist is reduced when the overhead monorail hoist goes down to make the overhead
monorail hoist safer.
The rack 3 is provided at upward or downward sections of the monorail 2.
A pitch diameter of the drive gear 13 is required to be greater than or equal to a
diameter of the lift wheel 14, so as to ensure that the drive gear 13 is well engaged
with the rack 3. Otherwise, since the lift wheels 14 contact with the guide rail, the
driving gear 13 only meshes with a small part of the rack 3, or even cannot mesh with
the rack, so it cannot act as expected.
In this embodiment, a hoist beam 20 is provided at the bottom of the lifting
device; two ends of the hoist beam 20 are respectively fixed under the two lifting
devices; and the car 19 is fixed under the two lifting devices via the hoist beam.
It should be understood that the hoist beam 20 may be fixed to one lifting device,
or connect multiple lifting devices simultaneously.
In this embodiment, the drive element 7 is an electric motor, and an output shaft
of the electric motor is connected to the driving gear 10.
In some embodiments, the electric motor may be a permanent magnet motor.
Compared with electric excitation motors, the permanent magnet motor, especially a
rare earth permanent magnet motor, has the characteristics of a simple structure,
reliable operation, small size, light weight, small loss and high efficiency. In this
embodiment, the electric motor may be designed as a constant torque motor to ensure
11
17424017_1(GH Matters) P113263.AU the operation of the overhead monorail hoist, i.e., the torque is maintained to be relatively constant by adjusting rotation speed to continuously drive the overhead monorail hoist to move. In some embodiments, the overhead monorail hoist further comprises a power unit 22 for supplying power to the drive element 7 and the control device 21, and the power unit 22 is electrically connected to the drive element 7 and the control device 21. In some embodiments, the control device 21 and the power unit 22 are arranged in a relatively sealed box which is fixed at the hoist beam next to a driver room 18. In some embodiments, the overhead monorail hoist may be controlled in a distributed manner; each drive element 7 has a separate control module; and the control module controls the element element 7 according to instructions of the control device 21. In some embodiments, the control device 21 may be a computer with a motor control adapter. The above embodiments are merely some preferred embodiments, which are not intended to limit the scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall fall within the scope of the present invention.
