Description

Technical Field

[0001] The present application relates to the technical field of belt conveyors, and in particular to a steel cable belt conveyor. Background Art

[0002] Belt conveyor is one of the important material transportation equipment in my country, which can realize continuous transportation of materials. The traditional belt conveyor is supported by rollers to complete the transportation work. Multiple rollers are fixed side by side on the track, supporting the moving conveyor belt to transport materials. For this type of roller-supported conveyor belt, there is relative movement between the rollers and the conveyor belt. The depression resistance between the conveyor belt and the rollers, the rotation resistance of the rollers themselves, and the extrusion resistance between the conveyor belt and the material will cause great transportation resistance. The large transportation resistance will increase the operating energy consumption and the operating tension of the conveyor belt, which will affect the service life of the conveyor belt. In addition, due to the relative movement between the rollers and the conveyor belt, the improper installation of the rollers will also twist the conveyor belt, which is prone to deviation. The depression resistance between the conveyor belt and the rollers and the wear resistance between the conveyor belt and the material will cause a large transportation resistance. If the transportation distance is too long, it will further increase the transportation resistance of the conveyor, resulting in serious wear of the conveyor belt and reduced transportation power.

[0003] When the conveyor belt is conveying materials, the conveying pressure acts directly on the rollers. The rollers do not move with the conveyor belt but support and transport the conveyor belt through their own rotation. As a result, the rollers are prone to wear, aging and even falling off, which seriously affects the conveying work. Therefore, it is necessary to frequently inspect, repair and replace the rollers. However, when conveying over long distances, it will pass through some remote and uneven places. Therefore, it will become very difficult to inspect and replace the rollers, which will require a lot of manpower, material resources and time. When conveying over large spans and long distances such as across rivers and mountains, it is necessary to install a large number of densely packed and evenly spaced hanging rollers on the suspended overhead cables. The hanging rollers wrap around the conveyor belt downwards to complete the conveying work. Therefore, when inspecting and other maintenance work on the hanging rollers, it is also necessary to do it in mid-air, which will become very difficult.

[0004] In summary, the traditional belt conveyor has the following problems when conveying with rollers supporting the conveyor belt: 1. The conveying resistance between the conveyor belt and the roller is very large, and the operating energy consumption is high.

[0005] 2. Large conveying resistance requires the use of a conveyor belt with a large initial tension, which will reduce the service life of the conveyor belt, and the friction between the roller and the conveyor belt will also damage the conveyor belt.

[0006] 3. The relative movement between the conveyor belt and the roller causes the conveyor belt to deviate.

[0007] 4. It is difficult to carry out inspection and other maintenance work on rollers, which requires a lot of manpower, material resources and time.

[0008] 5. When transporting over a large span, maintenance work such as inspection of hanging rollers is huge and dangerous.

[0009] 6. For long-distance field projects with complex terrain, the difficulty of implementing the corridor structure will increase, which will greatly increase investment and may even make it difficult to implement. Summary of the invention

The roller 33, the conveyor belt and the traction wire rope 9 are provided, and the driving roller 33 drives the conveyor belt and the traction wire rope 9 to operate.

When the conveyor belt is conveying, the belt trolley and the connecting rope are driven to move synchronously through the belt and the traction wire rope 9.

[0047] See also Figure 8 As shown, the fixed hanger 1 includes two pulleys, which form a double-layer structure to ensure a firm and reliable connection. The pulleys on the fixed hanger 1 play a supporting and guiding role, and each pulley can rotate independently to reduce friction resistance.

[0048] See also Figure 2 As shown, the reversing hub structure 6 includes a head reversing hub 61 and a tail reversing hub 62, wherein the head reversing hub 61 is rotatably arranged on the head fixing frame 4, and the tail reversing hub 62 is rotatably arranged on the tail fixing frame 5. The head reversing hub 61 and the tail reversing hub 62 are transmission-connected, and the head reversing hub 61 and the driving drum 33 are transmission-connected via a traction wire rope 9. The transmission connection between the head reversing hub 61 and the tail reversing hub 62 ensures the smooth operation of the conveyor belt during the entire conveying process, and reduces the occurrence of jamming and damage risks caused by improper steering.

[0049] See also Figure 2As shown, the belt trolleys 7 are arranged at intervals on the traction wire rope 9 and the track wire rope 8, and the transmission rates of the belt trolleys 7, the traction wire rope 9 and the conveyor belt are the same. Each belt trolley 7 is provided with a supporting groove for limiting the shape of the conveyor belt, which effectively prevents the conveyor belt from being offset or deformed during transportation and improves the conveying accuracy and reliability. The traction wire rope 9 is provided with a reversing winding structure for changing the carrying relationship between the conveyor belt trolley 7 and the traction wire rope 9 at the head reversing hub 61 and the tail reversing hub 62. The reversing winding structure makes the conveyor belt trolley 7 always located on the traction wire rope 9, so that the traction wire rope 9 can support the conveyor belt trolley 7. The traction wire rope 9 is wound around the tensioning drum 32, the driving drum 33, the head reversing hub 61, the tail reversing hub 62 and the tail drum 34 for multiple times in sequence, so that the position of the traction wire rope 9 and the belt trolley 7 is changed, so that the belt trolley 7 does not interfere when the head reversing hub 61 and the tail reversing hub 62 move and reverse, and the traction wire rope 9 can always support the belt trolley 7 and move synchronously.

[0050] See also Figure 1 and Figure 2 As shown, the belt trolley 7 is arranged at intervals between the traction wire rope 9 and the track wire rope 8, which prevents mechanical failure caused by excessive concentration; the transmission rates of the belt trolley 7, the traction wire rope 9 and the conveyor belt are the same, which ensures the synchronous movement of the entire system, avoids the slippage caused by asynchrony, and improves the stability and safety of the system operation; each belt trolley 7 is provided with a supporting groove for limiting the shape of the conveyor belt, which effectively prevents the conveyor belt from being offset or deformed during transportation, and improves the transportation accuracy and reliability.

[0051] See also Fig.10 As shown, the tape trolley 7 includes a tape trolley wheel 71, a bracket 72 and a support 73. The support 73 is installed on the fixed hanger 1. A frame bracket is provided on the bracket 73. The bracket 72 is symmetrically hinged on both sides of the frame bracket. The free end of each bracket 72 is driven by its own gravity to pivot around the corresponding hinge point. The tape trolley wheel 71 is installed on the support 73. The tape trolley 7 replaces the traditional roller, eliminates the relative movement between the roller and the conveyor belt, and reduces the conveying resistance.

[0052] When the belt trolley 7 is placed on the traction wire rope 9, the bracket 72 rotates in the direction away from the transmission conveyor belt due to its own gravity, the two brackets 72 are in an open state, and the conveyor belt is placed in the supporting groove to stably support the conveyor belt and prevent the conveyor belt from being displaced or deformed during transportation; when the belt trolley 7 is hung upside down on the traction wire rope 9, the bracket 72 rotates in the direction close to the transmission conveyor belt due to its own gravity, the two brackets 72 are in a closed state, and the conveyor belt is placed on the two brackets 72 to prevent the conveyor belt from detaching from the belt trolley, thereby ensuring the safety and reliability of the conveying process, which not only effectively reduces the conveying resistance and reduces the conveying energy consumption, but also prolongs the service life of the conveyor belt and improves the stability and safety of the conveying system.

[0053] The conveyor belt and the traction wire rope 9 are wound together on the driving drum 33 and the tensioning drum 32. The traction wire rope 9 is wound around the driving drum 33 and has more than one turn. The traction wire rope 9 and the conveyor belt are driven at a synchronous speed, utilizing the synergistic effect of the traction wire rope 9 and the conveyor belt to ensure that the two always remain synchronized during operation, eliminating slippage and improving the reliability of the conveying system.

[0054] The conveyor belt and traction wire rope 9 are both wound around the tensioning drum 32 and, after a 180-degree reversal, the conveyor belt and traction wire rope 9 remain in a tensioned state. It is also necessary to ensure that they can provide sufficient tension so that the conveyor belt maintains a stable tension during the entire operation process, thereby avoiding the risk of loosening or derailment.

[0055] The implementation principle of a steel cable belt conveyor in an embodiment of the present application is as follows: by introducing a belt trolley 7 to replace traditional rollers, the relative movement between the rollers and the conveyor belt is reduced. The belt trolley 7 makes there is no relative movement between the conveyor belt and the belt trolley, which greatly reduces the conveying resistance, reduces the conveying energy consumption, and extends the service life of the conveyor belt. The belt trolley 7 effectively avoids the conveyor belt from running off the track, simplifies the inspection and maintenance work, and is particularly suitable for long-distance and large-span conveying application scenarios. The entire system ensures the safety and stability of the conveying process through the synergistic effect of the traction wire rope 9 and the conveyor belt, and achieves the goal of high efficiency and energy saving.

[0056] Embodiment 2 Based on the above embodiment, it also includes a hanging fixed steel wire rope, the steel wire rope track is hung in the air through the suspended hanging fixed load-bearing cable, the belt trolley runs on the rope track, and the wheels of the belt trolley run on the rope track. A rope track is set between the head fixing frame 4 and the tail fixing frame 5, the rope track is hung in the air through the suspended load-bearing cable, and the belt trolley runs on the rope track, which can adapt to the long-distance, cross-river or cross-mountain large-span bulk material transportation. During the large-span transportation, the belt trolley is suspended in the air. Since the belt trolley and the traction steel wire rope 9 move synchronously with the conveyor belt, the inspection and other maintenance work of the trolley does not need to be carried out in the air, and can be uniformly set at the head or tail of the machine for easy maintenance, which greatly reduces the workload and difficulty of work, and reduces the danger of aerial maintenance of the belt trolley. The conveying resistance formed by the rolling friction between the wheels of the belt trolley and the rope rail track is much smaller than the conveying resistance between the roller and the conveyor belt, which greatly improves the operation effect and reduces the conveying energy consumption. In addition, the belt trolley runs smoothly on the rope rail track, which can increase the belt speed and save the conveying cost.

[0057] The rope track can be set up as a single track or a double track rope track according to the load requirements. The rope track is fixed with several fixed frames along the conveying direction, and the two sides of the fixed frames are fixedly connected to the load-bearing cables respectively. After the conveyor belt and the traction wire rope 9 drive the belt trolley to transport the materials from the rope track of the conveying section, they return to the starting point from the return section and start the conveying work in a cycle. By setting up a fixed frame, the rope track of the conveying section and the traction wire rope 9 of the return section are fixed or supported on the load-bearing cable, so that the rope track and the traction wire rope 9 can be suspended in the air to meet the large-span conveying requirements.

[0058] The spacing between adjacent fixed frames is the same, and a connecting rod with a stable structure is also provided in the fixed frame. The rope rail track is connected to the fixed frame through a rope clamp, and one side of the rope clamp is fixedly connected to the fixed frame, and the other side is fixedly connected to the lower part of the rope rail track. By connecting the rod in the fixed frame, the overall stability of the fixed frame is enhanced, and the stability of the entire conveying channel is guaranteed. By setting the rope clamp, the fixed frame is fixedly connected to the rope rail track, and the rope clamp is fixedly connected to the lower part of the rope rail track, which will not affect the running of the tape trolley on the rope rail track.

[0059] Embodiment 3 Based on the structural foundation of the first embodiment, it also includes a rope track; the rope track and the traction wire rope 9 are supported on the ground by the fixed bracket 72, and the belt trolley travels on the rope track. The rope track supported by the bracket 72 meets some low-height conveying scenarios, and the belt trolley travels on the rope track to convey bulk materials. The conveyor belt drives the belt trolley to move synchronously, and the belt trolley travels on the rope track to move to a specific position for unified inspection, maintenance and replacement, etc., which greatly saves manpower, material resources and time. The conveying resistance formed by the rolling friction between the wheels of the belt trolley and the rope track is much smaller than the conveying resistance between the roller and the conveyor belt, which greatly improves the operation effect and reduces energy consumption. The belt trolley travels smoothly on the rope track, improves the belt speed, increases the conveying efficiency, and saves the conveying cost. The conveyor belt is connected into a closed ring, and they are tensioned with a tensioning device. Driven by the motor, the conveyor belt is continuously operated by the friction between the conveyor belt, the traction wire rope 9 and the driving roller, thereby achieving the purpose of transporting the cargo from the loading end to the unloading end.
