The present application relates to maintenance for belt conveyors, and more
particularly to a conveyor belt replacement device and a belt pulling mechanism for
a belt conveyor.
Belt conveyors, which are carriers for carrying and transporting coal, are
important and irreplaceable equipment in coal production and are an extremely
important part for transporting coal from the working surface to the ground.
However, during the long-term use of the conveyor belt, frictions exist between belt
surfaces and materials and between the conveyor belt and rollers, resulting in
scratches on the belt surface, and even corrosion and fracture of the steel wire ropes,
which is a hidden danger during the operation of the conveyor belt. Therefore, in
order to ensure the safe and stable operation of the conveyor belt, the conveyor belt
must be replaced regularly. With the continuous increase of the coal transport
volume, the length, volume and weight of the conveyor belt also increase
correspondingly. In addition, the surrounding conditions of the belt conveyor are
complicated, so the work of replacing the conveyor belt is very complicated and
arduous. Especially, for conveyors with large inclinations and long distances, the
conveyor belt thereof is hard to be replaced, and accidents such as belt slipping and
belt breakage are easy to be caused. In addition, the underground operation is forced
to stop to replace the conveyor belt. Therefore, the replacement time of the conveyor
belt directly affects the production and economic benefits of the coal mine, so it is
17730765_1 (GHMatters) P113133.AU important to shorten the replacement time of the conveyor belt to improve the economic efficiency of the coal industry.
In view of the above problems, various conveyor belt replacement devices are proposed in this industry. However, existing conveyor belt replacement devices have the defects of a high energy consumption, large volume, complicated structure and unreliable operation.

In this embodiment, illustrated are a conveyor belt replacement device and a
conveyor belt pulling mechanism for a belt conveyor. The conveyor belt pulling
mechanism comprises a frame, a fixed belt press seat and a movable belt press seat.
The fixed belt press seat is fixed on the frame, and the movable belt press seat is
slidably mounted on the frame, and the movable belt press seat reciprocates relative
to the fixed belt press seat. A conveyor belt passes through the movable belt press
seat and exits from the fixed belt press seat. The fixed belt press seat and the
movable belt press seat alternately press the conveyor belt, and the conveyor belt
pulling mechanism pulls the conveyor belt to move when the movable belt press seat
reciprocates.
The principle of the embodiment of the invention is described as follows. When
the fixed belt press seat and the movable belt press seat alternately press the
conveyor belt, an old conveyor belt is pulled to be removed from the belt conveyor,
and a fresh conveyor belt is pulled to be laid on the belt conveyor at the same time
through the reciprocating motion of the movable belt press seat. Hydraulic pressure
is used as a power, which is in low in energy consumption and small in volume, and
the movable belt press seat is driven by a hydraulic cylinder to reciprocate,
eliminating a mechanism that converts a rotation into a linear movement, so the
6
17730765_1 (GHMatters) P113133.AU invention has a simple structure and reliable operation.
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are used only to illustrate the invention and not to limit the invention.
It should be noted that in the description of the embodiments of the present invention, unless otherwise specified and limited, the term "connection" should be understood in a board sense. For example, it can be an electrical connection, a communication between two elements, a direct connection, or indirect connection via an intermediate medium. For those skilled in this art, the specific meaning of the above term can be understood according to a specific situation.
In order to better understand the conveyor belt replacement device and the conveyor belt pulling mechanism of the belt conveyor, the whole conveyor belt replacement process of the belt conveyor is introduced before introducing the conveyor belt replacement device and the conveyor belt pulling mechanism. The conveyor belt replacement process includes the following steps. Firstly, the operation of the belt conveyor is stopped, and the power driving device is separated from the conveyor belt to make the conveyor belt in a free state. Secondly, the conveyor belt is fixed on the ground or underground ground. If the belt conveyor is an inclined shaft conveyor, the conveyor belt replacement device of the inclined shaft conveyor is fixed below the head of the upper part of the conveyor. If the belt conveyor is a conveyor of other types, the conveyor belt replacement device of the conveyor can be fixed at any position below the conveyor, preferably at both ends of the conveyor. Thirdly, the used conveyor belt under the belt conveyor corresponding to the conveyor belt replacement device is cut off; and then one end of the used conveyor is connected to a rewinding mechanism of the conveyor belt replacement device, and the other end thereof is connected to a releasing mechanism of the conveyor belt 7
17730765_1 (GHMatters) P113133.AU replacement device and a replacing conveyor belt. When connecting, it is also necessary to fix a special connecting belt at the head of the two sections of conveyor belts at the cutting-off point of the conveyor belt, because after cutting, the conveyor belt is not long enough to be connected to the rewinding mechanism and the unwinding mechanism at the same time. Finally, the conveyor belt pulling mechanism and rewinding mechanism of the conveyor belt replacement device are turned on to start the replacement.
The replacement can have two working modes. One working mode is an
automatic mode, in which the conveyor belt pulling mechanism and the unwinding
mechanism run continuously until the operator stops the machine, and the other
working mode is a jog mode, that is, the conveyor belt pulling mechanism and the
unwinding mechanism are automatically stopped after they are started for a preset
time. For example, after working for 1 minute, they are automatically stopped. The
jog mode is suitable for debugging or finding faults.
Example 1
The present embodiment provides a conveyor belt pulling mechanism. As
shown in FIGS. 1 and 2, the conveyor belt pulling mechanism comprises a frame 1, a
fixed belt press seat 2 and a movable belt press seat 3. The fixed belt press seat 2 is
fixed on the frame 1, and the movable belt press seat 3 is slidably mounted on the
frame 1, and the movable belt press seat 3 reciprocates relative to the fixed belt press
seat 2. The conveyor belt 6 passes from the movable belt press seat 3 and exits from
the fixed belt press seat 2. The fixed belt press seat 2 and the movable belt press seat
3 alternately press the conveyor belt 6, and the conveyor belt pulling mechanism
pulls the conveyor belt 6 to move when the movable belt press seat 3 reciprocates.
In this way, when the fixed belt press seat 2 and the movable belt press seat 3
8
17730765_1(GHMatters) P113133.AU alternately press the conveyor belt 6, the old conveyor is pulled to be removed from the belt conveyor when the movable belt press seat 3 reciprocates, and the fresh conveyor is pulled to be laid on the belt conveyor at the same time. Specifically, the process may include the following steps.
1) The conveyor belt 6 is tightly fixed by the belt press seat 2, and the movable
belt press seat 3 releases the conveyor belt 6; the movable belt press seat 3 moves to
a limit position far away from the fixed belt press seat 2. The conveyor belt 6
remains stationary when the movable belt press seat 3 moves.
2) The movable belt press seat 3 presses the conveyor belt 6, and the fixed belt
press seat 2 releases the conveyor belt 6; the movable belt press seat 3 moves to a
limit position close to the fixed belt press seat 2. Since the conveyor belt 6 is pressed
by the movable belt press seat 3, and the fixed belt press seat 2 is released, the
conveyor belt 6 moves when the movable belt press seat 3 moves, and enters the
rewinding mechanism by passing through the fixed belt press seat 2.
If the above steps are repeated, the conveyor belt 6 can be pulled out of the belt
conveyor. Specifically, the implementation of the belt conveyor of the above steps
may be controlled by Programmable Logic Controller (PLC).
As shown in FIGS. 1-3, the frame 1 is provided with afirst hydraulic cylinder
11 which drives the movable belt press seat 3 to reciprocates. The fixing end of the
first hydraulic cylinder 11, that is, the cylinder body, is fixed to the frame 1. The
power output end of the first hydraulic cylinder 11, that is, the piston rod 111, is
connected to the movable belt press seat 3. The piston rod 111 and the movable belt
press seat 3 move in the same direction. However, the hydraulic pressure is used as
the power, so that the conveyor belt pulling mechanism has a low energy
consumption and small volume, and the hydraulic cylinder drives the movable belt
press seat 3 to reciprocate, eliminating mechanisms, such as screws and nuts, and
9
17730765_1 (GHMatters) P113133.AU gears and racks, that convert a rotation into a linear movement.
In this embodiment, the number of the first hydraulic cylinder 11 may be two, so that the belt conveyor can be provided with a greater power, and the movable belt press seat 3 suffers a more balanced force.
As shown in FIGS. 4 and 5, the frame 1 is provided with a guide rail 12 on which the movable belt press seat 3 reciprocates, and the movable belt press seat 3 is provided with a guide wheel 31 which moves on the guide rail 12. The guide rail 12 and the guide wheel 31 are matched in shape, so that the movable belt press seat 3 reciprocates more smoothly.
In this embodiment, the guide rail 12 may be a channel steel, and the guide wheels 31 may be rollers which are matched with the channel steel. In order to move smoothly, the number of rollers may be 8. For example, 4 rollers are arranged on each side.
The fixed belt press seat 2 and the movable belt press seat 3 each comprise a bracket 21 and a press plate. The press plate is capable of carrying out a pressing movement for pressing the conveyor belt 6 relative to the bracket 21. The bracket 21 is provided with a second hydraulic cylinder 23 which drives the press plate to carry out the pressing movement. The fixing end of the second hydraulic cylinder 23, that is, the cylinder body, is fixed on the bracket 21. A power output end of the second hydraulic cylinder 23, that is, the piston rod, is connected to the press plate. The piston rod and the press plate move in the same direction. The hydraulic pressure is used as a power of the pressing movement, which also makes the conveyor belt pulling mechanism of the conveyor belt low in energy consumption and small in volume, and does not need to convert a rotation into a translation mechanism. Moreover, the whole mechanism of the belt conveyor uses the hydraulic pressure as power, which can further simplify the structure of the belt conveyor. In some
10
17730765_1 (GHMatters) P113133.AU embodiments, the bracket 21 can be a rectangular frame formed by welding section bars, such as channel steels and angle steels. The conveyor belt 6 passes through the inner cavity of the rectangular frame, and the press plate is located above or below the conveyor belt 6.
In some embodiments, the press plate includes an upper press plate 221 arranged above the conveyor belt 6 and a lower press plate 222 arranged below the conveyor belt 6; the upper press plate 221 is connected to the piston rod of the second hydraulic cylinder 23 and the lower press plate 222 is located on a bottom of the bracket 21, and the upper press plate is capable of reciprocating based on the lower press plate. A anti-friction layer 223 is provided on sides, in contact with the conveyor belt 6, of the upper press plate 221 and the lower press plate 222, respectively (the anti-friction layer 223 of the upper press plate 221 is not shown in the drawings). In this embodiment, the anti-friction layer 223 is an ordinary rubber.
In this embodiment, the number of the second hydraulic cylinders 23 may be two, which can provide greater power, the press plate suffers a more balanced force.
As shown in FIGS. 1-3, an anti-deviation mechanism 4 is respectively arranged at outer sides of the fixed belt press seat 2 and the movable belt press seat 3. As shown in FIG. 6, the anti-deviation mechanism 4 comprises first horizontal guide rollers 41 arranged above and below the conveyor belt 6, and vertical rollers 42 arranged on both sides of the conveyor belt 6. The first horizontal guide rollers 41 and the vertical rollers 42 form a rectangular gap through which the conveyor belt 6 passes, and the conveyor belt 6 passes through the anti-deviation mechanism outside the movable belt press seat and exits from the anti-deviation mechanism outside the fixed belt press seat. The distance between the two vertical rollers 42 can be adjusted according to the width of the conveyor belt 6. In this way, the conveyor belt 6 is limited in the rectangular gap and the roller of the vertical roller 42 can rotate without damaging the edge of the conveyor belt 6. The anti-deviation mechanism 4 11
17730765_1(GHMatters) P113133.AU is fixed to the frame 1 via screws 43 and nuts 44.
An anti-overlapping mechanism 5 can be arranged between the fixed belt press seat 2 and the movable belt press seat 3 and comprises a second horizontal guide roller 51 arranged below the conveyor belt 6, and both ends of the second horizontal guide roller 51 are fixed to the frame 1. The second horizontal guide roller 51 is arranged below the conveyor belt 6, so that the conveyor belt 6 can be prevented from self-overlapping or winding in a loose state. It should be understood that the anti-overlapping mechanism 5 can also be provided with a blocking bar of a non-guide roller type to avoid the large gap between the guide rollers. In this embodiment, a second horizontal guide roller 51 and a blocking bar 52 are provided to better prevent the belt from overlapping.
A reset elastic component 24 which pushes the piston rod to extend out may be provided in the second hydraulic cylinder 23. When the second hydraulic cylinder 23 is reset, the reset elastic component 24 pushes the press plate to press the conveyor belt 6.

This embodiment provides a conveyor belt replacement device for the belt
conveyor, comprising a conveyor belt pulling mechanism, a belt releasing
mechanism for providing a fresh conveyor belt and a rewinding mechanism for
rewinding an old conveyor belt. One end of the old conveyor belt is connected with
the fresh conveyor belt released from the belt releasing mechanism, and the other
end of the old conveyor belt passes through the conveyor belt pulling mechanism
and is fixed to the rewinding mechanism.
Components, connection relationships and functions of respective components
of the conveyor belt pulling mechanism are same as those of the conveyor belt
pulling mechanism in the first embodiment, which are not described herein.
The conveyor belt replacement device of the embodiment adopts a hydraulic
pressure as a power thereof, which is low in energy consumption and small in
volume. The hydraulic cylinder drives the conveyor belt pulling mechanism to
reciprocate, thereby eliminating mechanisms that convert a rotation into a linear
movement. Therefore, the conveyor belt replacement device is simple in structure
and reliable in operation.
The above description is only preferred embodiments of the present invention
and is not intended to limit the scope of the present invention. Any modification,
equivalent substitution and improvement made within the spirit and principles of the
invention shall fall within the scope of the invention.
In the claims which follow and in the preceding description of the invention,
except where the context requires otherwise due to express language or necessary
implication, the word "comprise" or variations such as "comprises" or "comprising"
is used in an inclusive sense, i.e. to specify the presence of the stated features but not
to preclude the presence or addition of further features in various embodiments of
