Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to a suspended, steep-slope conveyor belt system. Background Technology

[0002] Large-angle corrugated sidewall belt conveyors, also known as steep-slope belt conveyors, are mainly used for continuous conveying of bulk materials at steep angles. They are commonly used in mining or dock material handling to accommodate the height difference between the starting and ending points of the material conveying process. Conventional steep-slope belt conveyors are installed and used with ground support, thus losing ground space. To address this, suspended steep-slope belt conveyors have been developed. As the name suggests, suspended steep-slope belt conveyors are installed and used with a suspended installation method, thus utilizing the ground space beneath the belt conveyor.

[0003] However, while suspended high-slope belt conveyors offer the advantage of effectively utilizing ground space, they also have a drawback: due to the suspended installation method, when the belt breaks laterally, the broken belt will slide down rapidly under the influence of gravity, causing a "flying belt" phenomenon. This "flying belt" phenomenon can easily cause the belt to hit the suspension rod or cause bulk materials on the belt to splash, potentially damaging the equipment or threatening the safety of personnel on site.

[0004] For emergency measures regarding lateral belt breakage in belt conveyors, existing technologies offer several solutions, such as installing belt break catchers on the belt conveyor. When a lateral break occurs, the catcher activates, clamping the belt from both the top and bottom to lock it in place. However, belts on steep-slope conveyors often have corrugated edges, making the catcher less effective at gripping such belts. This can lead to unstable or non-aggressive gripping, and the catcher can also damage the corrugated edges during clamping, causing secondary damage to the belt. Summary of the Invention

[0005] The purpose of this invention is to provide a suspended, steep-slope belt conveyor to solve the problem of belt slippage when a belt conveyor with corrugated sidewalls breaks laterally. When belt slippage occurs, the belt may hit the hanging rod or cause bulk materials on the belt to splash, which may damage the equipment or threaten the safety of personnel on site. This invention also addresses the shortcomings of existing solutions.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A suspended, steep-slope conveyor belt includes a frame and a rubber belt. The frame is suspended from the ceiling by a boom. A power module, a tensioning module, and idler rollers are also installed on the frame. The power module is located at the upper end of the frame and drives the rubber belt. The tensioning module is located at the lower end of the frame and adjusts the tension of the rubber belt. Multiple idler rollers are evenly distributed on the upper and lower sides of the frame to support the rubber belt. The rubber belt includes a belt body and crossbeams. The belt body has a closed annular structure and is rolled onto the frame. The inner wall of the belt body, the power module, the tensioning module, and the multiple idler rollers are all rolled together. The outer wall of the belt body has side guards on both sides. The crossbeams are horizontally positioned on the belt body. Two adjacent crossbeams and the side guards form a storage trough for storing bulk materials.

[0008] Specifically, a braking area is provided between the side guards on both sides and the left and right side walls of the conveyor belt body. The frame is equipped with at least two mounting brackets. Mounting plates are fixedly mounted on the left and right sides of the upper end face of each mounting bracket. A first wedge block is provided on the lower end face of each mounting plate. A second wedge block is provided below each first wedge block. The second wedge block is fixedly mounted on the upper end face of the mounting bracket. The lower end face of the first wedge block has a braking surface, and the upper end face of the second wedge block has a limiting surface. Both the braking surface and the limiting surface are inclined surfaces. The braking surface and the limiting surface are arranged opposite each other and form a trumpet shape facing the front end. The vertical projections of the braking surface and the limiting surface coincide and are both located within the braking area. A limiting roller is rolledly connected to the limiting surface. The diameter of the limiting roller is D. The minimum distance between the braking surface and the limiting surface is H. The thickness of the tape body is t, where Ht≤D. The second wedge block is provided with a driving component and a detection component. The driving component is used to drive the limiting roller to slide towards the end of the limiting surface that is higher. The detection component is used to detect the breakage position of the tape body and activate the driving component.

[0009] During equipment operation, when the conveyor belt breaks laterally, the broken section of the belt will sag due to loss of continuity. Under the influence of gravity, the sagling conveyor belt remains in contact with the detection component. When the detection component is in contact with the conveyor belt, it does not trigger the drive component. As the conveyor belt slides a distance on the idler rollers, the detection component loses the downward pressure from the conveyor belt after the broken section passes the detection component, thus detecting the broken section and activating the drive component. Once activated, the drive component drives the limit roller to slide towards the higher end of the limit surface until the limit roller slides to contact the lower end of the conveyor belt and pushes the conveyor belt upward until the upper end of the conveyor belt contacts the braking surface. At this point, the upper end of the limit roller and the braking surface form a clamping structure for the broken conveyor belt. Furthermore, the diameter of the limiting roller is D, the minimum distance between the braking surface and the limiting surface is H, and the thickness of the tape body is t, where Ht ≤ D. Therefore, the limiting roller can smoothly slide to fit against the lower end face of the tape body and be clamped by the braking surface, thus locking the broken tape body and preventing it from continuing to slide down and causing a slippage. Simultaneously, since the limiting roller is rolled on the limiting surface, it can roll on the limiting surface during the clamping and locking process, thereby preventing scratches on the tape body and protecting it.

[0010] Preferably, the driving assembly includes a tension spring and a slider. The second wedge block has a mounting groove extending through both the upper and lower sides in its middle. The front end of the mounting groove extends through the front end face of the second wedge block, while the rear end does not extend through the second wedge block. Both the tension spring and the slider are located within the mounting groove. The rear end of the tension spring is fixedly connected to the second wedge block, and the front end is fixedly connected to the slider. The slider is slidably installed within the mounting groove. A groove is provided on the upper end face of the slider. A sliding plate is provided at the lower end of the limiting roller. The sliding plate extends into the groove, and the sliding plate and the groove are slidably installed. The detection assembly is located at the front end of the slider. When the detection assembly is in contact with the tape body, the tension spring is in a stretched state.

[0011] During equipment operation, when the conveyor belt body is intact, the detection component remains in contact with the lower end face of the conveyor belt body. At this time, the tension spring remains stretched, and the lower end face of the limiting roller is in contact with the limiting surface, while the sliding plate is slidably installed within the groove. When the conveyor belt body breaks, the broken section sags due to loss of continuity. As the conveyor belt body continues to slide forward on the idler roller assembly, the broken section gradually separates from the detection component. At this point, the detection component loses the pressure of the conveyor belt body, and the tension spring pulls the slider towards the rear of the mounting groove. The slider then drives the limiting roller towards the higher part of the limiting surface until the outer wall of the limiting roller is in contact with the lower end face of the conveyor belt body, pushing the conveyor belt body upwards until the upper end face of the conveyor belt body is in contact with the braking surface. At this point, the outer wall of the limiting roller and the braking surface form a clamping and locking structure on the conveyor belt body, preventing the broken conveyor belt body from continuing to slide down and effectively preventing belt slippage.

[0012] Preferably, the detection assembly includes a pull rod, a limiting rod, a limiting wheel, and a pulley. Two cantilever arms are fixedly installed on the front end face of the second wedge block, and the two cantilever arms are symmetrically arranged on the left and right sides of the mounting groove. The rear end of the pull rod is threadedly connected to the slider. The limiting rod is fixedly installed on the front end of the pull rod. The limiting wheel is rotatably installed on the front end of the cantilever arm through a pin shaft and is located between the two cantilever arms. A rocker arm is provided on the outer side wall of the limiting wheel. The pulley is rotatably installed on the end of the rocker arm away from the limiting wheel. A limiting groove penetrating the left and right sides is opened on the outer side wall of the limiting wheel. When the pulley is in rolling connection with the lower end face of the tape body, the limiting rod is slidably installed in the limiting groove, and the tension spring is in a stretched state.

[0013] During equipment operation, when the conveyor belt is intact, the pulley remains in rolling contact with the lower end face of the conveyor belt. Simultaneously, the limiting rod is slidably installed within the limiting groove, restricting the position of the pull rod and preventing it from moving under the force of the tension spring. When the conveyor belt breaks, the broken section sags due to discontinuity. As the conveyor belt slides further on the idler rollers, the broken section passes the pulley, separating from it. Under the pull of the tension spring, the pull rod drives the limiting rod to slide within the limiting groove until it exits. The tension spring then pulls the slider towards the rear of the mounting groove, causing the slider to move the limiting roller towards the higher part of the limiting surface until the outer wall of the limiting roller contacts the lower end face of the conveyor belt, pushing the conveyor belt upwards until the upper end face of the conveyor belt contacts the braking surface. This locks the broken conveyor belt, effectively preventing belt slippage.

[0014] Preferably, the front end of the limiting roller is provided with a limiting protrusion, the cross-section of the limiting protrusion is rectangular, the thickness of the limiting protrusion is B, and t / 2≤B≤t.

[0015] By setting a limiting protrusion on the limiting roller, after the outer wall of the tape body is in contact with the lower end face of the tape body, due to the friction between the limiting roller and the tape body, the limiting roller will roll as the tape body slides. The limiting protrusion will gradually approach the lower end face of the tape body during the rolling process until it is in contact with the lower end face of the tape body. After the limiting protrusion is in contact with the lower end face of the tape body, the contact area between the limiting roller and the lower end face of the tape body is increased, thereby improving clamping stability. When the limiting roller pushes the tape body upwards to contact the braking surface, the limiting protrusion can embed into the lower end face of the tape body, effectively preventing the tape body from sliding or falling off during clamping, further enhancing the locking effect on the broken tape body. Furthermore, the thickness B of the limiting boss is set to t / 2≤B≤t, and the minimum distance H between the braking surface and the limiting surface is set to Ht≤D. After the limiting roller rotates, the limiting boss contacts the lower end face of the conveyor belt body and pushes the conveyor belt body upward until the upper end face of the conveyor belt body is in contact with the braking surface. This accelerates the formation of a clamping and locking structure between the limiting roller and the braking surface, improves the braking speed of the limiting roller on the conveyor belt body, and ensures the safety of the transportation equipment and the site.

[0016] Preferably, a friction layer is provided on the outer side wall of the upper end of the limiting roller, the friction layer extends to the left and right sides of the limiting roller, the front end of the friction layer extends to the upper end face of the limiting protrusion, and the friction layer covers one-third of the outer side wall of the limiting roller.

[0017] By providing a friction layer on the outer wall of the limiting roller, when the limiting roller contacts and rolls with the conveyor belt, the friction layer increases the friction between the limiting roller and the conveyor belt, thereby more effectively preventing the conveyor belt from slipping during clamping. Furthermore, the friction layer extends to the left and right sides of the limiting roller and the upper surface of the limiting protrusion, increasing the contact area and friction between the limiting roller and the conveyor belt, preventing slippage between the conveyor belt and the limiting roller, further improving clamping stability, and ensuring the safety of the transport equipment and the site.

[0018] Preferably, the front end of the limiting protrusion has a rounded corner at the top corner, and the radius of curvature of the rounded corner is equal to the thickness of the tape body.

[0019] By using rounded corners, when the front end of the limiting protrusion contacts the lower end face of the tape body, the rounded corners guide the limiting protrusion to gradually embed into the lower end face of the tape body, preventing the limiting protrusion from scratching or damaging the tape body. Simultaneously, the rounded corner design reduces the frictional resistance between the limiting protrusion and the tape body, allowing the limiting protrusion to embed more smoothly into the lower end face of the tape body, improving clamping efficiency and further enhancing the locking effect on the broken tape body.

[0020] Preferably, the braking surface is provided with multiple anti-slip grooves, the depth of the anti-slip grooves is 3-5mm, the multiple anti-slip grooves are set at an angle to the side wall of the first wedge block, and the inclination direction of the anti-slip grooves is towards the front side of the first wedge block.

[0021] By incorporating multiple anti-slip grooves on the braking surface, when the limiting roller pushes the broken conveyor belt upwards to contact the braking surface, the anti-slip grooves increase the friction between the braking surface and the conveyor belt, thus more effectively preventing the conveyor belt from slipping or detaching during clamping. Furthermore, the multiple anti-slip grooves are angled to the sidewall of the first wedge block, with the inclination direction pointing towards the front of the first wedge block. This design allows the conveyor belt to be more easily locked by the braking surface along the inclination direction of the anti-slip grooves when subjected to clamping force, further improving clamping stability and braking effect. Simultaneously, the depth of the anti-slip grooves is set to 3–5 mm, ensuring sufficient friction while avoiding excessive wear on the conveyor belt, thus guaranteeing the long-term stable operation of the transport equipment.

[0022] Preferably, the second wedge block has limiting plates on its left and right sides, the limiting roller is located between the two limiting plates, and guide grooves are opened on the side walls of the two limiting plates facing the limiting roller. The guide grooves are parallel to the limiting surface, and the limiting roller is coaxially connected to a rotating shaft. The left and right ends of the rotating shaft are slidably installed in the guide grooves.

[0023] By setting limiting plates on both sides of the second wedge block, and creating guide grooves parallel to the limiting surface on these plates, the rotating shaft of the limiting roller can be slidably mounted within the guide grooves. This design ensures that the limiting roller remains on the correct trajectory during sliding, preventing deviation or wobbling. Simultaneously, the limiting plates also constrain and protect the limiting roller, preventing damage due to excessive force during clamping. Furthermore, the parallel arrangement of the guide grooves and the limiting surface ensures that the limiting roller remains parallel to the limiting surface during sliding, thereby improving clamping stability and accuracy.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The suspended high-slope conveyor belt of the present invention, through the braking surface and the limiting surface, in conjunction with the function of the limiting roller detection component and the limiting component, can respond quickly when the conveyor belt body breaks, effectively preventing the broken conveyor belt body from continuing to slide down and causing the belt to fly off, thus ensuring the safety of the conveyor equipment and the site.

[0026] 2. By incorporating limiting protrusions and a friction layer on the limiting rollers, the stability and friction of the clamping are further enhanced, allowing the broken conveyor belt to be more effectively locked and preventing it from continuing to slide down. Simultaneously, the design of the limiting protrusions and friction layer also reduces damage to the conveyor belt itself, ensuring the long-term stable operation of the transport equipment.

[0027] 3. The present invention also improves the friction between the braking surface and the belt body by optimizing the anti-slip groove design on the braking surface, making the belt body easier to lock when subjected to clamping force, thereby further improving the braking effect and safety of the equipment.

[0038] Please see Figures 1 to 9 This invention provides a suspended, steep-slope conveyor belt transport device, the technical solution of which is as follows:

[0039] A suspended, steep-slope conveyor belt system, see reference. Figure 1 and Figure 2 The system includes a frame 1 and a rubber belt 2. The frame 1 is suspended from the ceiling by a boom.

Two adjacent cross partitions 203 and the side guards 202 on both sides form a storage trough, which is used to store bulk materials.

[0040] For details, please refer to Figures 3 to 6A braking area is provided between the side guards 202 on both sides and the left and right side walls of the conveyor belt body 201. At least two mounting brackets 3 are provided on the frame 1. Mounting plates 4 are fixedly installed on the left and right sides of the upper end face of the mounting brackets 3. A first wedge block 5 is provided on the lower end face of each mounting plate 4. A second wedge block 6 is provided on the lower side of each first wedge block 5.

The slider 9 is slidably installed within the mounting groove 604. A sliding groove 901 is provided on the upper end face of the slider 9. A sliding plate 16 is provided at the lower end of the limiting roller 7. The sliding plate 16 extends into the sliding groove 901, and the sliding plate 16 is slidably installed with the sliding groove 901. The detection assembly includes a pull rod 11, a limiting rod 12, a limiting wheel 13, and a pulley 14. The second wedge... Two cantilever arms 10 are fixedly installed on the front end face of block 6. The two cantilever arms 10 are symmetrically arranged on the left and right sides of the mounting groove 604. The rear end of the pull rod 11 is threadedly connected to the slider 9. The limiting rod 12 is fixedly installed on the front end of the pull rod 11. The limiting wheel 13 is rotatably installed on the front end of the cantilever arm 10 through a pin shaft and is located between the two cantilever arms 10. A rocker arm 1301 is provided on the outer wall of the limiting wheel 13. A pulley 14 is rotatably installed on the end of the rocker arm 1301 away from the limiting wheel 13. A limiting groove 1302 penetrating the left and right sides is opened on the outer wall of the limiting wheel 13. When the pulley 14 is in rolling contact with the lower end face of the tape body 201, the limiting rod 12 is slidably installed in the limiting groove 1302, and the tension spring 8 is in a stretched state.

[0041] See Figure 5 and Figure 6The front end of the limiting roller 7 is provided with a limiting protrusion 701. The cross-section of the limiting protrusion 701 is rectangular and the thickness of the limiting protrusion 701 is 15mm. The top corner of the front end of the limiting protrusion 701 is provided with a rounded corner 702. The radius of curvature of the rounded corner 702 is equal to the thickness of the tape body 201. A friction layer 15 is provided on the outer wall of the upper end of the limiting roller 7. The friction layer 15 extends to the left and right sides of the limiting roller 7. The front end of the friction layer 15 extends to the upper end face of the limiting protrusion 701. The friction layer 15 covers one-third of the outer wall of the limiting roller 7.

[0042] See Figure 5 and Figure 6 The braking surface 501 is provided with multiple anti-slip grooves 502, the depth of which is 4mm. The multiple anti-slip grooves 502 are set at an angle to the side wall of the first wedge block 5, and the inclination direction of the anti-slip grooves 502 is towards the front side of the first wedge block 5. The left and right sides of the second wedge block 6 are provided with limiting plates 602, and the limiting roller 7 is located between the two limiting plates 602. The side walls of the two limiting plates 602 facing the limiting roller 7 are provided with guide grooves 603, which are parallel to the limiting surface 601. The limiting roller 7 is coaxially connected to a rotating shaft, and the left and right ends of the rotating shaft are slidably installed in the guide grooves 603.

[0043] When working, refer to Figures 1 to 9During equipment operation, the power module 17 provides traction force to the conveyor belt body 201, which rotates cyclically under the traction force of the power module 17. Simultaneously, the idler roller group 19 rolls and rubs against the conveyor belt body 201. When the conveyor belt body 201 is not broken, the pulley 14 remains in rolling contact with the lower end face of the conveyor belt body 201. Meanwhile, the limiting rod 12 is slidably installed in the limiting groove 1302, limiting the position of the pull rod 11 and preventing it from moving under the action of the tension spring 8. When the conveyor belt... After the main body 201 breaks, the tape body 201 at the break point sags due to loss of continuity. As the tape body 201 slides a distance on the idler roller group 19, the distance gradually increases. At this point, after the tape body 201 at the break point passes the pulley 14, the tape body 201 separates from the pulley 14. Under the pulling action of the tension spring 8, the pull rod 11 drives the limiting rod 12 to slide in the limiting groove 1302 until the limiting rod 12 slides out of the limiting groove 1302. The tension spring 8 then pulls the slider 9 to move to the rear side of the mounting groove 604. The slider 9 drives the limiting roller 7 to move towards the higher part of the limiting surface 601 until the friction layer 15 on the limiting roller 7 is in contact with the lower end face of the tape body 201. After the friction layer 15 is in contact with the lower end face of the tape body 201, due to the friction between the friction layer 15 and the tape body 201, the limiting roller 7 will roll as the tape body 201 slides. The limiting protrusion 701 will gradually approach the lower end face of the tape body 201 during the rolling process of the limiting roller 7. The rounded corner 702 can guide the limiting protrusion 701 to gradually embed. The lower end face of the tape body 201 is protected from scratches or damage caused by the limiting protrusion 701 until the limiting protrusion 701 is in contact with the lower end face of the tape body 201. The limiting protrusion 701 pushes the tape body 201 upward until the upper end face of the braking area on the tape body 201 is in contact with the braking surface 501. The outer wall of the limiting roller 7 and the braking surface 501 form a clamping and locking structure for the tape body 201, thereby locking the broken tape body 201 and effectively preventing the occurrence of tape flying.
