Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to an inertia increasing component, a belt conveyor and a conveying system. Background Art

[0002] In a "pot-bottom" roadway, when a single belt conveyor cannot meet the laying requirements, usually a downward belt conveyor and an upward belt conveyor need to be overlapped to complete the operation. When the two conveyors are overlapped, if there is a power failure or an emergency stop, the free stop time of the upward belt conveyor is shorter than that of the downward belt conveyor. At this time, when there is a sudden power failure or an emergency stop, the downward belt conveyor will continuously unload materials onto the upward belt conveyor, and the downward belt conveyor is prone to a "runaway" accident, while the upward belt conveyor is prone to coal stacking. When the two overlapped conveyors stop with power on, the shutdown time of the whole line is long, increasing the safety hazard time and having poor economy.

[0003] When there is a power failure or an emergency stop, in order to prevent the downward belt conveyor from "running away" or the upward belt conveyor from having coal stacking, it is necessary to reduce the stop time of the downward belt conveyor. The methods to reduce the stop time are as follows: 1. Increase the braking torque of the braking device, and at the same time, improve the performance of the transmission device; 2. Install a damping device to increase the frictional resistance, but the damping device is easy to wear the belt; 3. Equip with a standby power supply. The above methods have high input costs and high maintenance costs. Summary of the Invention

[0047] Embodiments of the present invention will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0048] As Figures 1 to 7 shown, the belt conveyor 1000 according to an embodiment of the present invention includes a conveyor body 200 and an inertia increasing assembly 100.

[0049] The conveyor body 200 has a power output shaft 201.

[0050] The inertia increasing assembly 100 includes a mounting wheel 1, an inertia increasing wheel 2, and a connecting member 3. The mounting wheel 1 is mounted on the power output shaft 201. A first mounting groove 11 is provided on the outer peripheral surface of the mounting wheel 1. The inertia increasing wheel 2 is rotatably sleeved on the mounting wheel 1. The distance between the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2 gradually decreases. That is to say, the bottom wall surface on one side of the first mounting groove 11 is farther from the inner peripheral surface of the inertia increasing wheel 2 than the bottom wall surface on the other side of the first mounting groove 11. The connecting member 3 is movably disposed in the first mounting groove 11 between a working position where it can abut against each of the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2 and a disengaged position where it disengages from at least one of the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2.

[0051] The mounting wheel 1 of the inertia increasing assembly 100 according to an embodiment of the present invention is mounted on the power output

[0052] shaft 201 of the conveyor body 200. When the conveyor body 200 is in an open state, the power output shaft 201 of the conveyor body 200 rotates, and the mounting wheel 1 rotates synchronously with the power output shaft 201. In other words, when the belt conveyor 1000 is in an open state, the power output shaft 201 is in a rotating state, and the mounting wheel 1 is also in a rotating state.

[0053] Taking Figure 1 and Figure 6 as an example, the following usage process of the belt conveyor 1000 according to an embodiment of the present invention is described: When the conveyor body 200 is turned on, the power output shaft 201 starts to rotate counterclockwise, and the rotation speed gradually

[0054] increases to a set speed, and the mounting wheel 1 rotates counterclockwise synchronously with the power output shaft 201. It should be noted that in the counterclockwise rotation direction of the mounting wheel 1, this side of the first mounting groove 11 is in front of the other side of the first mounting groove 11. That is to say, this side of the first mounting groove 11 is the front side of the first mounting groove 11, and the other side of the first mounting groove 11 is the rear side of the first mounting groove 11. When the mounting wheel 1 rotates, the connecting member 11 is pushed by the bottom wall surface and / or side wall surface of the first mounting groove 11 of the mounting wheel 1

[0055] Rotate counterclockwise with the installation wheel 1. When the installation wheel 1 has not started to rotate and its rotation speed is relatively low, the connecting member 11 is adjacent to this side of the first installation groove 11 (the front side of the first installation groove 11), and the connecting member 11 is in this disengaged position. As the rotation speed of the installation wheel 1 increases, due to the relative lag of the movement of the connecting member 11 in the first installation groove 11 with respect to the installation wheel 1, the connecting member 3 moves relative to the installation wheel 1, and the connecting member 3 moves from this side of the first installation groove 11 to the other side (moves from the front side of the first installation groove 11

[0056] to the rear side of the first installation groove 11). The distance between the connecting member 3 and at least one of the bottom wall surface of the first installation groove 11 and the inner peripheral surface of the inertia increasing wheel 2 gradually decreases. When the connecting member 3 moves to abut against each of the bottom wall surface of the installation groove 11 and the inner peripheral surface of the inertia increasing wheel 2, that is, when the connecting member 3 moves to this working position, the connecting member 3 is stuck by the installation groove 11 and the inertia increasing wheel 2 and no longer moves. That is to say, the connecting member 1 in this working position abuts against each of the installation wheel 1 and the inertia increasing wheel 2, forming a state where the connecting member 1 is stuck between the installation wheel 1 and the inertia increasing wheel 2, so that the frictional force between the connecting member 3 and each of the installation wheel 1 and the inertia increasing wheel 2 increases. The installation wheel 1 is the driving member, the connecting member 3 is the force transmission component between the installation wheel 1 and the inertia increasing wheel 2, and the static frictional force exerted by the connecting member 3 on the inertia increasing wheel 2 is the force that drives the inertia increasing wheel 2 to rotate counterclockwise, thereby causing the inertia increasing wheel 2 to rotate synchronously with the installation wheel 1 under the action of this force.

[0057] When the conveyor body 200 is in normal operation, when the conveyor body 200 suddenly loses power or stops emergently, the rotation speed of the power output shaft 201 has a tendency to gradually decrease, and the rotation speed of the installation wheel 1 installed on the power output shaft 201 also has a tendency to gradually decrease. However, the inertia wheel 2 has a large rotational inertia. Driven by the rotational inertia of the inertia wheel 2, the installation wheel 1 continues to rotate counterclockwise at the same speed as or close to the set speed, and at the same time, the power output shaft 201 continues to rotate counterclockwise at the same speed as or close to the set speed under the drive of the installation wheel 1, so that the conveyor body 200 continues to maintain a running state for a period of time, that is, the conveyor body 200 continues to maintain a conveying operation state of conveying materials for a period of time.

[0058] Starting from the moment when the conveyor body 200 is powered off or stops operating, the inertia wheel 2, under the action of rotational inertia, acts as a driving member to drive the connecting member 3 to rotate counterclockwise. The connecting member 3 serves as a force transmission component between the inertia increasing wheel 2 and the mounting wheel 1, such that the frictional force exerted by the connecting member 3 on the mounting wheel 1 is a force that drives the mounting wheel 1 to rotate in the counterclockwise direction. Since the connecting member 3 is disposed in the first mounting groove 11 and the first mounting groove 11 has a certain space, during the transmission of rotational motion between the connecting member 3 and the mounting wheel 1, the connecting member 3 acts as a driving member for driving the mounting wheel 1 to rotate, and the force exerted on the connecting member 3 by the mounting wheel 1 is a resistance force in the clockwise direction, causing the connecting member 3 to have a tendency to disengage from the mounting wheel 1. When the connecting member 3 moves counterclockwise relative to the mounting wheel 1 (the connecting member 3 gradually moves from the rear side of the first mounting groove 11 to the front side of the first mounting groove 11), the static frictional force between the connecting member 3 and each of the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2 disappears, and the connecting member 3 moves to this disengaged position, then the inertia increasing wheel 2 and the mounting wheel 1 disengage, and the inertia increasing wheel 2 and the mounting wheel 1 no longer rotate synchronously, and each of the inertia increasing wheel 2 and the mounting wheel 1 gradually stops rotating, and the conveyor body 200 stops conveying materials.

[0059] The inertia increasing assembly 100 according to the embodiment of the present invention enables the mounting wheel 1 not to drive the inertia increasing wheel 2 to rotate during the initial stage of rotation of the mounting wheel 1 (i.e., the stage with a relatively low speed) through the connecting member 3 disposed in the first mounting groove 11 of the mounting wheel 1, reduces the rotational resistance during the initial stage of driving the mounting wheel 1 to rotate by the power output shaft 201, is beneficial for protecting the power output shaft 201, and improves the speed increasing efficiency of the power output shaft 201 and the mounting wheel 1 during the initial stage of rotation, and can avoid the extension of the start-up time period between the moment when the conveyor body 200 is started and the operating state of conveying materials, and ensure the normal start-up time of the conveyor body 200. As the rotational speed of the mounting wheel 1 increases, under the action of the mounting wheel 1 and the first mounting groove 11, the connecting member 3 moves from this disengaged position to this working position, causing the connecting member 3 to be stuck between the inertia increasing wheel 2 and the mounting wheel 1, so that the inertia increasing wheel 2 rotates synchronously with the mounting wheel 1, and the inertia increasing wheel 2 starts to store rotational inertia. When the conveyor body 200 that drives the mounting wheel 1 to rotate is powered off or emergently stops operating, the inertia increasing wheel 2 starts to release rotational inertia, and the mounting wheel 1 continues to rotate at a high speed at or close to the set speed for a period of time under the drive of the rotational inertia of the inertia increasing wheel 2, which is equivalent to increasing the rotational inertia of the mounting wheel 1, extends the time from the moment of power off (or stop of operation) to the moment when the conveyor body 200 stops conveying materials, and extends the operating time of the conveyor body 200 for conveying materials, thereby avoiding the potential risk of material accumulation caused by continuous falling of external materials onto the conveyor body 200 when the conveyor body 200 of the belt conveyor 1000 is suddenly powered off or emergently stops operating.

[0060] Therefore, the inertia increasing assembly 100 in the embodiments of the present invention increases the rotational inertia of the mounting wheel 1, can extend the operation time of the conveyor body 200 after sudden power failure or emergency stop, that is, extends the time for conveying materials, and can solve the problem that the belt conveyor 1000 accumulates coal due to continuous falling of external coal materials onto the conveyor body 200 during sudden power failure or emergency stop. Moreover, the structure of the inertia increasing assembly 100 is simple, the cost is low, and it is convenient for maintenance.

[0061] To make the solution of the present application easier to understand, taking Figures 1 to 7 as an example, the belt conveyor 1000 in the embodiments of the present invention will be described.

[0062] Referring to FIG. 1, the belt conveyor 1000 in the embodiments of the present invention includes a conveyor body 200 and an inertia increasing assembly 100.

[0063] The conveyor body 200 has a driving device 202, a power output shaft 201, and a conveyor belt 203. The driving device 202 is connected to the power output shaft 201, and the power output shaft 201 is connected to the conveyor belt 203. When the driving device 202 is in an open state, the driving device 202 drives the power output shaft 201 to rotate, and the power output shaft 201 drives the conveyor belt 203 to rotate so as to transport the materials on the conveyor belt 203.

[0064] The inertia increasing assembly 100 includes a mounting wheel 1, an inertia increasing wheel 2, a connecting member 3, an elastic member 4, a sealing cover 5, a cage 7, a first sealing ring 8, a second sealing ring 9, and a plurality of rollers 6.

[0065] The mounting wheel 1 is sleeved on the power output shaft 201, and the mounting wheel 1 is fixedly connected to the power output shaft 201 through a shrink disc 10.

[0066] A first mounting groove 11 is provided on the outer peripheral surface of the mounting wheel 1, and the distance between the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2 gradually decreases. The bottom wall surface of this side (the front side of the first mounting groove 11 in the counterclockwise direction) of the first mounting groove 11 is farther from the inner peripheral surface of the inertia increasing wheel 2 than the bottom wall surface of the other side (the rear side of the first mounting groove 11 in the counterclockwise direction) of the first mounting groove 11.

[0067] The inertia increasing wheel 2 is rotatably sleeved on the mounting wheel 1. The connecting member 3 is movably arranged in the first mounting groove 11 between a working position where it can abut against each of the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2 and a disengaging position where it disengages from at least one of the bottom wall surface of the first mounting groove 11 and the inner peripheral surface of the inertia increasing wheel 2.

[0068] Optionally, the bottom wall surface of the first installation groove 11 is a plane, and the bottom wall surface of the first installation groove 11 is perpendicular to one of the radial lines of the installation wheel 1, which facilitates the processing and forming of the first installation groove 11, reduces the manufacturing cost of the installation wheel 1, and further reduces the manufacturing cost of the inertia increasing assembly 100.

[0069] In some embodiments, the bottom wall surface of the first installation groove 11 intersects with the outer peripheral surface of the installation wheel 1. In other words, the bottom wall surface on the other side of the first installation groove 11 intersects with the outer peripheral surface of the installation wheel 1, which facilitates the processing and forming of the first installation groove 11, further reduces the manufacturing cost of the installation wheel 1, and further reduces the manufacturing cost of the inertia increasing assembly 100.

[0070] Optionally, the number of each of the first installation grooves 11 and the connecting members 3 is four, and the four first installation grooves 11 are evenly distributed along the circumferential direction of the installation wheel 1.

[0071] The installation wheel 1 is provided with a through hole extending along its axial direction, which reduces the self-weight of the installation wheel 1 and reduces the load for driving the installation wheel 1 to rotate when the conveyor body 200 starts. This not only helps to further protect the power output shaft 201, but also further avoids prolonging the startup time period of the conveyor body 200 due to the installation of the inertia increasing assembly 100 on the power output shaft 201.

[0072] In some embodiments, the connecting member 3 is of a cylindrical structure. The connecting member 3 of the cylindrical structure can roll in the first installation groove 11, making the movement of the connecting member 3 between the disengaged position and the working position more convenient. Moreover, the contact between the connecting member 3 of the cylindrical structure and each of the bottom wall surface of the first installation groove 11 and the inner peripheral surface of the inertia increasing wheel 2 is a line contact. When the connecting member 3 is in the working position, that is, when the connecting member 3 is in a state of being stuck between the installation wheel 1 and the inertia increasing wheel 2, the connecting member 3 has a certain contact area with each of the installation wheel 1 and the inertia increasing wheel 2. Therefore, it is beneficial to the force transmission between the installation wheel 1, the connecting member 3, and the inertia increasing wheel 2, ensures the stability of the movement transmission between the installation wheel 1, the connecting member 3, and the inertia increasing wheel 2, and improves the stability of the inertia increasing assembly 100.

[0073] One end of the elastic member 4 is connected to the side wall surface of the first installation groove 11, and the other end of the elastic member 4 is adjacent to the connecting member 3 located at the disengaged position. Refer to Figure 6As shown, the elastic member 4 is located on the front side of the connecting member 3 in the counterclockwise direction. The elastic member 4 can undergo elastic deformation under an external force. When the connecting member 3 moves from this working position to this disengaging position, that is, when the connecting member 3 moves from the rear side of the first mounting groove 11 to the front side of the first mounting groove 11, when the connecting member 3 touches the elastic member 4, the elastic member 4 deforms under the force, absorbing a part of the kinetic energy of the connecting member 3, reducing the moving speed of the connecting member 3, buffering the movement of the connecting member 3, and preventing the connecting member 3 from colliding with the first mounting groove 11. At the same time, if a part of the connecting member 3 touches the elastic member 4, under the action of the elastic member 4, the moving speed of this part of the connecting member 3 will be reduced or even redirected, which can prevent the connecting member 3 from moving obliquely in the first mounting groove 11, ensure that the axis of the connecting member 3 is parallel to the axis of the mounting wheel 1, prevent the connecting member 3 located at this disengaging position from getting stuck in the first mounting groove 11, ensure the smoothness and safety of the movement of the connecting member 3 in the first mounting groove 11, and further ensure the safety and stability of the inertia increasing assembly 100.

[0074] Specifically, the elastic member 4 is a spring. The spring has a simple structure and low cost.

[0075] A second mounting groove 111 is provided on the side wall surface of this side of the first mounting groove 11, and this end of the elastic member 4 is connected to the side wall surface of the second mounting groove 111. The setting of the second mounting groove 111 increases the space of the first mounting groove 11, facilitates the installation and fixation of the elastic member 4, and reduces the assembly difficulty of the inertia increasing assembly 100.

[0076] In some other embodiments, a guide rail is provided in the first mounting groove 11, and a guide groove is provided on the connecting member 3, and the guide rail is fitted in the guide groove. The cooperation of the guide rail and the guide groove can play a guiding and limiting role in the movement of the connecting member 3, and can also ensure the smoothness and safety of the movement of the connecting member 3 in the first mounting groove 11.

[0077] Sealing caps 5 are provided at both ends of the inertia increasing wheel 2 in its axial direction, and the sealing caps 5 correspond to the mounting wheel 1 in the axial direction of the mounting wheel 1. The two sealing caps 5 form limits on both sides of the mounting wheel 1 in its axial direction, preventing the inertia increasing wheel 2 and the mounting wheel 1 from disengaging, and improving the safety of the inertia increasing assembly 100.

[0078] One of the outer peripheral surface of the mounting wheel 1 and the inner peripheral surface of the inertia increasing wheel 2 is provided with a slideway, the slideway is arranged along the circumferential direction of the mounting wheel 1, and the slideway is located between the connecting piece 3 and the sealing cover 5 in the axial direction of the mounting wheel 1. The roller 6 is arranged in the slideway and is rollably connected to each of the outer peripheral surface of the mounting wheel 1 and the inner peripheral surface of the inertia increasing wheel 2. The cage 7 is arranged between the outer peripheral surface of the mounting wheel 1 and the inner peripheral surface of the inertia increasing wheel 2, and a plurality of limiting holes are provided on the cage 7, and the limiting holes cooperate with the plurality of rollers 6. Each of the outer peripheral surface of the mounting wheel 1 and the inner peripheral surface of the inertia increasing wheel 1 is in rolling connection with the roller 6, and the cage 7 ensures the relative position relationship between the rollers 6. The roller 6 and the cage 7 form a structure similar to a bearing, ensuring the smoothness of the relative rotation between the mounting wheel 1 and the inertia increasing wheel 2, ensuring the concentricity between the mounting wheel 1 and the inertia increasing wheel 2, and reducing the wear degree between the mounting wheel 1 and the inertia increasing wheel 2.

[0079] The roller 6 and the cage 7 can be lubricated with grease.

[0080] Specifically, the slideway is arranged on the outer peripheral surface of the mounting wheel 1.

[0081] In some embodiments, a first groove is provided on the outer peripheral surface of the mounting wheel 1, the first groove is located between the connecting piece 3 and the roller 6 in the axial direction of the mounting wheel 1, a second groove is provided on the sealing cover 5, and each of the first groove and the second groove is arranged along the circumferential direction of the mounting wheel 1. The first sealing ring 8 is arranged in the first groove, and the first sealing ring 8 abuts against the inner peripheral surface of the inertia increasing wheel 2. The second sealing ring 9 is arranged in the second groove, and the second sealing ring 9 abuts against the mounting wheel 1. The first sealing ring 8 and the second sealing ring 9 seal the space between the outer peripheral surface of the mounting wheel 1 and the inner peripheral surface of the inertia increasing wheel 2, so that the roller 6 located between the first sealing ring 8 and the second sealing ring 9 in the axial direction of the mounting wheel 1 is sealed, avoiding the leakage of the grease used to lubricate the roller 6.

[0082] Next, the conveying system 10000 of the embodiment of the present invention will be described.

[0083] As Figures 1 to 8 shown, the conveying system 10000 of the embodiment of the present invention includes a down-conveyor belt conveyor 2000 and an up-conveyor belt conveyor 3000. The up-conveyor belt conveyor 3000 is lapped with the down-conveyor belt conveyor 2000, and the up-conveyor belt conveyor 3000 is the belt conveyor 1000 of the embodiment of the present invention.
