Abstract
Description
Technical Field
[0001] The invention relates to a multi-point driven energy-saving belt conveyor, which is a general mechanical equipment and a transport equipment for bulk goods. Background Art
[0002] Most existing belt conveyors use fixed buffer rollers to support the belts, and use the friction between the drive roller and the belt to drag the belt and then continuously convey the bulk materials on the belt. The energy consumption during the conveying process is closely related to the running resistance. Although there are many types of running resistance components of belt conveyors, the most important ones are still the depression resistance when the lower surface of the conveyor belt contacts the rollers and the rotation resistance of the rollers themselves, which account for nearly 70% of the running resistance. This is also an important reason why the energy consumption of belt conveyors has remained high. Although the removal of rollers can reduce running resistance and energy consumption, the belt is a flexible body, and the lack of bottom roller support cannot achieve continuous conveying function. There is a certain contradiction between the two. Summary of the invention
[0003] In order to overcome the problems of the prior art, the present invention proposes a multi-point drive energy-saving belt conveyor. The belt conveyor adopts a method of arranging hub motors on each supporting roller to evenly distribute the drag force, improve the drag efficiency, and significantly reduce energy consumption.
[0004] The objective of the present invention is achieved in this way: a multi-point driven energy-saving belt conveyor, comprising: a support frame with upper and lower tracks on both sides, rollers are respectively provided at the front and rear ends of the support frame, a belt is provided on the roller, a plurality of roller frames are evenly distributed on the belt, spanning the tracks on both sides and fixedly connected to the transport belt, rollers with hub motors are provided on both sides of the roller frame, a connecting beam is provided between the rollers on both sides, and a power battery is provided in the connecting beam.
[0005] Furthermore, the track is an I-shaped steel rail.
[0006] Furthermore, the roller has a rim.
[0007] Furthermore, the roller is provided with a driving device.
[0008] Furthermore, edge belts are provided on both sides of the belt.
[0009] Furthermore, the connecting beam is arranged between the goods and the belt.
[0010] Furthermore, the belt is arranged between the goods and the connecting beam.
[0011] Furthermore, a groove for accommodating the connecting beam is provided on the drum.
[0012] Furthermore, an energy management device is provided on the connecting beam.
[0013] Furthermore, the connecting beam is provided with a contact or non-contact charging device.
[0014] The beneficial effects of the present invention are as follows: the present invention utilizes the hub motor to make each connecting beam a power source, and each power source is operated with a belt, so that the power is distributed on the entire belt. At the same time, rollers and rails are used to carry the weight of the material, thereby reducing the friction of the belt during movement, improving the overall efficiency of the belt conveyor, improving the energy utilization rate of the belt conveyor, and realizing green and energy-saving transportation.

[0021] Embodiment 1:
[0022] This embodiment is a multi-point drive energy-saving belt conveyor. Figure 1 , 2 This embodiment comprises: a support frame 1 with upper and lower tracks 101 on both sides, rollers 2 are respectively provided at the front and rear ends of the support frame, belts 3 are provided on the rollers, multiple roller frames 4 are evenly distributed on the belts and cross the tracks on both sides and are fixedly connected to the transport belts, rollers 401 with hub motors are provided on both sides of the roller frames, connecting beams 402 are provided between the rollers on both sides, and power batteries are provided in the connecting beams.
[0023] This embodiment adopts the method of roller support on both sides, and a group of roller frames with rollers are set at a certain distance on the belt. In the middle of the roller frame is a connecting beam connected to the belt as a whole. Both ends of the connecting beam are provided with rollers that roll on the track, and the rollers are equipped with hub motors, and the connecting beam is equipped with rechargeable power batteries, so that each roller frame is a driving source for driving the belt. After the belt conveyor is started, each roller acts as an independent driving unit to realize the multi-point coordinated drive of the belt conveyor. In the process of feeding materials, the running resistance of the belt conveyor described in this embodiment mainly occurs between the rollers and the guide rails, and its equivalent friction coefficient is much smaller than the fixed rollers of the traditional belt conveyor. Therefore, the overall power is effectively reduced.
[0024] The rollers at both ends of the belt conveyor can be powered. When the belt conveyor starts, the drive roller rotates to drive the belt to move linearly along the track. At this time, the track wheel is in a free driven state. When the belt conveyor starts and is in a uniform motion state, the hub motors scattered along the conveyor belt start to gradually replace the drive rollers to realize the multi-point drive of the belt conveyor to complete material transportation. During the feeding process, the collaborative control strategy can be used to achieve efficient and energy-saving operation of the belt conveyor. When the belt conveyor is unloaded and returning, the hub motor energy feedback technology can be used to achieve energy storage, further improve the energy utilization rate of the belt conveyor, and achieve green and energy-saving transportation.
[0025] The rails can be made of strip materials with various cross-sectional shapes, such as I-beams, channel steels, light rails, etc. Correspondingly, the rollers can also be made of rollers of various shapes, such as steel rollers with rims. The rims are embedded in the rails, which can effectively solve the deviation during movement.
[0026] In order to prevent the material from leaking to both sides of the belt, side guard belts can be provided on both sides of the belt to prevent the material from leaking.
[0027] There are two ways to combine the belt and the roller frame. One is that the belt is on the roller frame, that is, the roller frame supports the belt, and the other is that the roller frame is under the belt, that is, the roller frame hangs the belt. Both methods have their own advantages and can be used in different occasions.
[0028] Since there is a power battery in the connecting beam, an energy management device can be set in the connecting beam to manage the energy stored in the battery, including using energy feedback collection technology to store electricity and reuse energy during unloading and unloaded return. And charging management. The battery can be charged by disassembly charging or online charging. Online charging can be contact charging or contactless charging.
[0029] Embodiment 2:
[0030] This embodiment is an improvement of the first embodiment and is a refinement of the track of the first embodiment. The track described in this embodiment is an I-shaped steel rail. Figure 2 .
[0031] The advantages of using I-shaped light rails are large load-bearing capacity and good wear resistance. These characteristics are particularly important for equipment such as conveyors that are used continuously for a long time.
[0032] Embodiment three:
[0033] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the roller. The roller described in this embodiment has a rim 4011, see Figure 2 .
[0034] This is a common conventional track wheel with mature manufacturing technology, reliable performance and low cost. This embodiment adopts this roller to match the track, which can effectively solve the problem of running deviation.
[0035] Embodiment 4:
[0036] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the roller. The roller described in this embodiment is provided with a driving device.
[0037] The driving device of the rolling belt can enhance the uniformity of the driving force and can also be used as the starting power. When the belt conveyor starts, since there is no material loaded on the belt, the pressure of each roller frame on the track is small, and the friction generated is also small, so it is easy to slip. At this time, you can start the roller first, use the roller with greater friction to drive the belt to overcome the greater starting force, and then use each hub motor to start smoothly.
[0038] Embodiment five:
[0039] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the belt. The belt described in this embodiment is provided with side belts 301 on both sides. Figure 1 , 2 .
[0040] The structure of the side belt is very simple and the cost is low, and the side belt is required to have strong telescopic properties.
[0041] Embodiment six:
[0042] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment regarding the position of the belt and the connecting beam. The connecting beam described in this embodiment is arranged between the goods 5 and the belt, such as Figure 3 shown.
[0043] The belt in this embodiment is under the connecting beam during the process of carrying the material, that is, the belt is suspended under the connecting beam, and the material covers the connecting beam and the belt. When there is no material, the connecting beam is exposed on the belt surface, which looks a bit like the scraper of a scraper, but the scraper has relative movement with the belt below, while in this embodiment, the connecting beam and the belt below do not have relative movement, but are fixed together, which is conducive to pushing the material forward.
[0044] Embodiment seven:
[0045] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment regarding the position of the belt and the connecting beam. The belt described in this embodiment is arranged between the goods and the connecting beam, such as Figure 4 shown.
[0046] In this embodiment, the belt is above the connecting beam during the process of carrying the material, that is to say, the connecting beam supports the belt. In this case, the connecting beam is stressed, so it can carry the material with a larger weight.
[0047] Embodiment eight:
[0048] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the roller. In this embodiment, a groove 201 for accommodating the connecting beam is provided on the roller. Figure 5 shown.
[0049] Since the connecting beam is located below the belt, when the drum rolls the belt, the connecting beam sinks into the groove of the drum, forming a condition similar to that of a synchronous toothed belt.
[0050] Embodiment nine:
[0051] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment regarding the position of the belt and the connecting beam. An energy management device is provided on the connecting beam described in this embodiment.
[0052] The function of the energy management device is to detect the energy status in the battery and allocate the use of the battery. Under normal circumstances, the power batteries are generally divided into multiple groups, and the energy management device allocates the use according to the power of the battery. When a group of batteries is running low on power, the battery group will be withdrawn from use and another battery with sufficient power will be selected for use. When there is a charger, the battery with more power will be charged first so that it can quickly enter the working state. If the wheel hub motor energy feedback technology is used to achieve energy storage when returning empty during the material transportation process, the energy utilization rate of the belt conveyor can be further improved to achieve green and energy-saving transportation.
[0053] Embodiment ten:
[0054] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment regarding the position of the belt and the connecting beam. The connecting beam described in this embodiment is provided with a contact or non-contact charging device.
[0055] There are various types of existing charging devices, such as contact charging and non-contact charging. Contact charging is to set a long electrode along the direction of belt movement, and set brushes on each connecting beam. When the brush on the connecting beam contacts the long electrode, charging begins, and when it separates, charging ends. Since the belt is reciprocating, it can be charged continuously.
[0056] Contactless charging uses inductive charging, which can also achieve good charging results.
[0057] Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred arrangement scheme, a person skilled in the art should understand that the technical solution of the present invention (such as the driving mode of the motor, the form of the support frame, the operation mode of the belt conveyor, etc.) can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
