Description

Technical Field

[0001] This application relates to the field of conveyor technology, specifically to a distributed drive system for a conveyor and a conveyor. Background Technology

[0002] Traditional belt conveyors primarily use idlers and supports in the transport system to connect the conveyor belt into a closed loop, and rely on roller motors and rollers at both ends of the belt system for drive. Because the friction between the rollers and the belt needs to be converted into drag force, the actual effective power loss of the roller motors is huge.

[0003] The power range of drum motors is generally 300-1200KW, with a price of 400,000-2 million RMB per drive. They have high daily power consumption and high system operating costs. In addition, in order to achieve effective conversion of driving force, a belt tensioning device must be installed to maintain belt tension, which significantly increases the system construction cost and complexity.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Application content

[0005] To address the shortcomings of existing technologies, this application discloses a distributed drive system and conveyor that can solve the problems of high power consumption and large losses in the operation of traditional belt conveyors.

[0006] To achieve the above objectives, this application provides the following technical solution: A distributed drive system for a conveyor includes a frame with multiple drive sources distributed along it. These drive sources are connected to the same control system. Each drive source has a fixed frame for connecting a transmission belt. A track is provided on the frame, and the multiple drive sources move synchronously along the track. The transmission belt moves with the drive sources. The track includes a forward section, a return section, and a reversing section. The reversing section is located between the forward and return sections and is used for moving a drive source from the forward section to the return section or vice versa.

[0007] In a preferred embodiment, one of the reversing sections extends from the end of the forward section to the end of the return section, and the other reversing section extends from the end of the return section to the end of the forward section, with the two opposing reversing sections disconnected from each other.

[0008] In a preferred embodiment, one end of the reversing section is connected to the end of the return section, and the other end of the reversing section extends towards the end of the forward section, with the end of the reversing section and the end of the forward section being disconnected.

[0009] In a preferred embodiment, one end of the reversing section is connected to the end of the forward section, and the other end of the reversing section extends toward the end of the return section, with the end of the reversing section and the end of the return section being disconnected.

[0010] In a preferred embodiment, the frame is formed by connecting a center section, an extension section, and a bending section. The reversing section is provided in the bending section and is arc-shaped. The arc-shaped reversing section is used for turning the drive belt around.

[0011] In a further preferred embodiment, the extension section is configured as a straight line, which is used for the transmission belt to move in a straight line; or the extension section is configured as an arc, which is used for the transmission belt to turn.

[0012] In a preferred embodiment, the drive source includes a drive hub that moves along a track, the drive hub is connected to a hub motor, and the hub motor is connected to a fixed frame.

[0013] A further preferred technical solution is that the frame is provided with continuously extending energized contact pieces, and the drive source is provided with an electric slider. The electric slider and the energized contact pieces are in contact, and the electric slider and the energized contact pieces together supply power to the hub motor.

[0014] In addition, this application also discloses a conveyor, including a distributed drive system for the conveyor and a transmission belt, wherein the distributed drive system for the conveyor is any one of the distributed drive systems for the conveyor described in the above technical solutions.

[0015] In a preferred embodiment, the transmission belt includes a scale-type transmission belt, the scale-type transmission belt is connected to a fixing frame, a connector is provided between adjacent scale-type transmission belts, and adjacent scale-type transmission belts can rotate relative to each other.

[0016] This application discloses a distributed drive system and a conveyor, which has the following advantages: The multi-drive source configuration completely eliminates the need for large drive rollers at both ends, completely removing idlers and belt tensioners, reducing investment in system equipment and components, simplifying system configuration, and significantly lowering system construction and maintenance costs. Distributed small drive sources replace traditional drive roller motors, solving the problems of high power and cost associated with traditional motors, and the need for larger drive motors over long distances due to insufficient power. It also addresses the issues of high starting torque requirements and high starting current of traditional motors, greatly reducing starting current and energy consumption during operation, resulting in more abundant power.

[0017] The drive source directly rolls to generate traction, and the weight of the material is supported by the drive hub and track. The drive source is both a support and a drive, reducing the extra consumption of overcoming gravity and friction. The rolling drive has no loss of overcoming friction, which will greatly improve the efficiency of the drive. Moreover, the driving force is evenly distributed on the entire belt surface, making the system run more smoothly.

[0018] The drive belt is fixed to the fixed frame and runs along the track inside the rail, so the drive belt will not deviate. This can greatly reduce the amount of maintenance and repair work in the later stage. At the same time, there is no relative movement between the belt surface and the fixed frame, unlike the traditional hair belt that rubs against the idler roller, which causes belt surface wear, tearing, and fire poisoning risks.

[0019] By setting up modular tracks, the tracks can be installed in any combination, facilitating transportation and relocation; at the same time, they are no longer limited by the length of transportation distance, and the length can be flexibly adjusted and assembled arbitrarily according to site needs.

[0020] The system can be equipped with scale belts, which allow for flexible assembly of modular tracks and segmented belt surfaces, significantly reducing equipment and labor costs during system construction and belt surface replacement. The use of scale-type drive belts and modular tracks enables the transportation system to turn and change direction in environments requiring cornering by replacing and installing cornering track ends, guided by the track.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0025] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0026] Example 1 like Figures 1 to 3 As shown, the distributed drive system for the conveyor protected in this application includes a frame 100 with an assembled annular shell. Multiple drive sources 400 are distributed on the frame 100, and the multiple drive sources 400 are connected to the same control system. Remote intelligent and automated control is achieved through intelligent algorithms combined with PLC, realizing control over the number and grouping of drive power groups, and precise adjustment and power distribution. At the same time, it can realize rapid detection and power switching of faulty drive points without stopping operation. Furthermore, through intelligent control, the distributed motor drives can be grouped and put into operation according to the real-time transport volume, and precise selection and regulation can be performed.

[0027] Each drive source 400 is provided with a mounting bracket 300 for connecting the drive belt 500. There are two frames 100, which are fixed together. Each frame 100 is assembled from three parts: multiple center sections 110, bending sections 120, and extension sections 130, wherein there are two center sections 110 located in the middle of the frame 100.

[0028] There are two bending sections 120 located at both ends of the frame 100, and multiple extension sections 130 located between the center section 110 and the bending sections 120. The center section 110, bending sections 120, and extension sections 130 are connected to each other by a fixing plate via a mating connector 140. The length of the entire frame 100 is changed by altering the number of extension sections 130. In this embodiment, the extension sections 130 are straight, and the straight extension sections 130 are used for the drive belt 500 to move in a straight line. In other embodiments, the extension sections 130 may be arc-shaped, and the arc-shaped extension sections 130 are used for the drive belt 500 to turn.

[0029] A track 150 is provided on the frame 100. Multiple drive sources 400 move synchronously along the track 150. The transmission belt 500 moves with the drive sources 400. The track 150 includes a forward section 151, a return section 152, and a reversing section 153. The reversing section 153 is located between the forward section 151 and the return section 152. The reversing section 153 is used for the drive sources 400 to move from the forward section 151 to the return section 152 or from the return section 152 to the forward section 151.

[0030] Each center section 110 and extension section 130 has a straight track 150 on its inner lower surface. The bending section 120 has a track 150 with a length of half that of the entire semi-circular bending section 120 on the corresponding surface of the track 150 on the upper and lower extension sections 130. The ends of half of the track 150 on the inner and outer end faces of the bending section 120 are chamfered. The reversing section 153 is set to be arc-shaped so that the drive source 400 can pass through and the transmission belt 500 can turn around.

[0031] like Figure 4 and Figure 4A As shown, regarding the distribution of the reversing segments 153, in this embodiment, one reversing segment 153 can extend from the end of the forward segment 151 to the end of the return segment 152, and another reversing segment 153 can extend from the end of the return segment 152 to the end of the forward segment 151, with the two opposing reversing segments 153 being disconnected from each other. That is, reversing segments 153 can be connected to both the forward segment 151 and the return segment 152.

[0032] In another embodiment, one end of the reversing segment 153 may be connected to the end of the return segment 152, and the other end of the reversing segment 153 may extend towards the end of the forward segment 151, with the end of the reversing segment 153 and the end of the forward segment 151 disconnected. That is, the reversing segment 153 is only connected to the return segment 152. In other embodiments, one end of the reversing segment 153 may be connected to the end of the forward segment 151, and the other end of the reversing segment 153 may extend towards the end of the return segment 152, with the end of the reversing segment 153 and the end of the return segment 152 disconnected. That is, the reversing segment 153 is only connected to the forward segment 151.

[0033] like Figures 5 to 8 As shown, the drive source 400 is installed at both ends of the fixed frame 300. The fixed frame 300 is movably installed on the track 150 inside the frame 100 on both sides via the drive sources 400 at both ends. The drive source 400 mainly consists of a hub motor 410, a drive hub 420 and an electric slider 430. The drive hub 420 is located at the circumferential end of the hub motor 410. Under the magnetic force of the hub motor 410, the drive hub 420 can rotate around the hub motor 410 and drive the entire drive source 400 to move along the surface of the track 150. The inner end of the drive hub 420 is provided with a flange 421. The flange 421 can ensure that the drive hub 420 does not deviate from the track 150 when it rolls on the track 150.

[0034] A track slot 160 is provided on the inner side of the frame 100, and the track slot 160 is arranged around the inner side of the frame. An energized contact piece 170 is also provided on the inner side of the upper and lower ends of the track slot 160. The upper and lower energized contacts 170 are respectively connected to the positive and negative power supplies, and the surface of the energized contact piece 170 is a conductive material. Two electric sliders 430 are arranged vertically along the inner end face of the hub motor 410. When the drive source 400 rolls on the track 150, the two electric sliders 430 on the drive source 400 will contact the upper and lower energized contacts 170 on the inner side of the frame 100, thereby energizing the drive source 400 through the energized contacts 170.

[0035] like Figures 3 to 5 As shown, there are multiple fixing frames 300, which are evenly installed between the two frames 100. The fixing frames 300 pass through the track slots 160 on the inner side of the frame 100 and are mounted on the track 150 inside the frame 100. The fixing frame 300 consists of a connecting rod 310 and a side support 320. The connecting rod 310 is a cylindrical rod with hollow ends. Multiple fixing holes 301 are evenly provided on the top surface of the connecting rod 310. Side supports 320 are also provided at both ends of the connecting rod 310.

[0036] Example 2 The conveyor of this application includes a distributed drive system for the conveyor and a transmission belt 500, wherein the distributed drive system for the conveyor is the distributed drive system of Embodiment 1.

[0037] In this embodiment, the transmission belt 500 is fitted onto the outer end of the frame 300. The transmission belt 500 can be fixedly connected to each fixed frame 300 by bolts or other fixing methods. When the fixed frame 300 moves along the frame 100 inside the frame 100, it will drive the transmission belt 500 to move.

[0038] In other embodiments, such as Figures 9 to 11 As shown, the transmission belt 500 may include a scale-type transmission belt 600, which is formed by multiple scale belts 610 overlapping each other along the outer periphery of the frame 100. Each adjacent scale belt 610 has a partially overlapping section, and each adjacent scale belt 610 is connected by a connector 620. The connector 620 has mounting heads 621 at both ends, which can be bolted or otherwise hinged to the mounting heads 621 at both ends of the connector 620. This allows each pair of adjacent scale belts 610 to rotate relative to the other via the connector 620, enabling the scale belts 610 to turn when overlapped with a turning support frame 200. The turning state is as follows: Figure 12 As shown, each scale belt 510 can be fixedly installed on the surface of the connecting rod 310 by bolts or other means in conjunction with the fixing holes 301 on the surface of the connecting rod 310, so that the transmission belt 500 moves together when the fixing frame 300 moves.
