Abstract

This invention discloses a long-distance, steep-slope conveyor belt installation system and its construction method. The system includes a belt-laying bracket at the head of the conveyor and a traction device positioned diagonally below the head of the conveyor. A first clamping device is installed between the belt-laying bracket and the head roller of the conveyor to prevent belt slippage. In this technical solution, the belt-laying bracket at the head of the conveyor can be used to lay down both the upper and lower layers of the conveyor belt. Both the upper and lower belts can be released using their own downward-sloping weight and the traction force of the traction device, avoiding the risk of belt slippage during installation. The first clamping device effectively prevents belt slippage and can be adjusted in real time according to the belt release speed and the traction force of the traction device. This ensures the safety of the belt installation process while facilitating installation, and also prevents the belt from being subjected to excessive tension, which could affect its performance.

Description

Technical Field

[0001] This invention relates to the field of belt conveyor installation technology, and in particular to a long-distance, steep-slope belt conveyor belt installation system and its construction method. Background Technology

[0002] Belt conveyors are a crucial method for muck removal in tunnel construction. With their application in long-distance, steep-slope tunnel construction projects such as mines and water diversion projects (e.g., long tunnels with gradients exceeding 25%), tunnel construction efficiency has been greatly improved. However, because auxiliary tunnels in mines and pumped-storage projects often involve long distances and steep gradients, segmented installation of belt conveyors in steep-slope auxiliary tunnels poses significant safety risks. Uncontrollable risks such as equipment slippage and belt slippage may occur, causing injury to installation personnel and equipment. Therefore, segmented belt installation can no longer meet the requirements for normal installation of belt conveyor equipment.

[0003] Although various installation and replacement methods for belt conveyors exist in the prior art, they still cannot solve the aforementioned technical problems. For example, Chinese invention patent CN 114147662 A, published on March 8, 2022, discloses a new process for replacing the conveyor belt in a mine main inclined shaft belt conveyor. This process utilizes a first and second braking device to first lock the conveyor belt, and then breaks the belt to be replaced at the head and tail of the conveyor. After breaking the belt, the new conveyor belt is guided to the first channel via a conveyor belt support frame, passes through a second floor, and connects to the old conveyor belt. Then, the old belt on the conveyor is replaced via a second drive roller, guide wheel, first drive roller, and first belt support roller. Because the belt is relatively heavy, the belt on the upper side of the conveyor is replaced first, followed by the belt on the lower side.

[0004] While the aforementioned patent application's technical solution utilizes a winch for belt recovery during belt replacement, improving work efficiency and safety, reducing the number of workers, lowering labor intensity, and shortening working time, it relies on the structural characteristics of each mine floor to set up corresponding conveyor belt support frames, adjustable supports, and other supporting facilities. This not only makes it unsuitable for the installation of conveyor belts in long-distance, steep-slope tunnels, but also fails to solve technical problems such as equipment slippage and belt slippage during conveyor belt installation.

[0005] Therefore, there is an urgent need to design a long-distance, steep-slope conveyor belt installation system and its construction method to overcome the above difficulties and achieve safe, reliable, and efficient installation of conveyor belts. Summary of the Invention

[0006] To address the shortcomings in the aforementioned background technology, this invention proposes a long-distance, steep-slope conveyor belt installation system and its construction method, which solves the technical problems of equipment slippage and conveyor belt slippage during the installation of conveyor belts in long-distance, steep-slope tunnels.

[0007] The technical solution of this application is as follows:

[0008] A belt installation system for a long-distance, steep-slope conveyor belt includes a belt release bracket set at the head of the conveyor belt and a traction device set at an angle below the head of the conveyor belt. A first clamping device is provided between the belt release bracket and the head roller of the conveyor belt to prevent the belt from slipping. This technical solution cleverly utilizes the application environment of long-distance, steep-slope belt conveyors. The belt release bracket at the head of the conveyor can be used to release both the upper and lower belt layers. Simultaneously, both the upper and lower belt layers can be released using their own downward weight and the traction force of the traction device during the descent to the bottom of the tunnel. The traction device also benefits from the upward pull of the belt, preventing the belt installation equipment from slipping. Furthermore, a first clamping device is installed between the belt release bracket and the head roller of the conveyor. This effectively prevents belt slippage and allows for real-time adjustment of the clamping state based on the belt release speed and the traction force of the traction device. This provides a suitable release speed that matches the traction force of the traction device, ensuring safety during belt installation while minimizing tension and preventing performance degradation due to excessive tension.

[0009] Furthermore, a long-distance, steep-slope conveyor belt installation system also includes a speed sensor for detecting the belt release speed. The speed sensor forms a closed-loop control unit with the first clamping device via a control module. When the release speed exceeds a threshold, the first clamping device increases the clamping force on the belt. Based on the above technical solution, this solution provides a preferred long-distance, steep-slope conveyor belt installation system that uses a speed sensor to monitor the belt release speed in real time and transmits the release speed information to the first clamping device in real time. The first clamping device can respond more quickly, achieving automated belt release.

[0010] Furthermore, a long-distance, steep-slope conveyor belt installation system also includes a tension sensor for detecting the traction force of the traction device. The tension sensor forms a closed-loop control unit with the first clamping device via a control module. When the traction force exceeds the maximum value of a threshold range, the first clamping device reduces the clamping force on the belt; when the traction force is less than the minimum value of the threshold range, the first clamping device increases the clamping force on the belt. Based on the above technical solution, this technical solution provides a preferred long-distance, steep-slope conveyor belt installation system. It uses a tension sensor to monitor the belt's traction force in real time and transmits the traction force information to the first clamping device in real time. The first clamping device can respond more quickly, achieving automated release of the belt. Simultaneously, using two sets of monitoring and control units allows for more reliable control of the belt release process; that is, the belt traction force monitoring and control unit can be shared with the belt release speed monitoring and control unit, ensuring belt release safety from two dimensions.

[0011] Furthermore, a second clamping device is provided at the head of the conveyor belt. Based on the above technical solution, this technical solution provides a preferred conveyor belt installation system for long-distance, steep-slope conveyors. The second clamping device can more reliably position the conveyor belt. After the upper and / or lower conveyor belts are released, the second clamping device positions the conveyor belt, and then vulcanization can be performed.

[0012] Furthermore, the first clamping device is a hydraulic clamping device, and the second clamping device is a mechanical clamping device. Based on the above technical solution, this technical solution provides a preferred long-distance, high-slope conveyor belt installation system. By employing two clamping devices and using two different clamping methods, the clamping and positioning of the conveyor belt is made safer and more reliable.

[0013] Alternatively, the traction device is a winch, which feeds back the belt's traction force to the first clamping device via an electrical signal. When the traction force exceeds the maximum value of a threshold range, the first clamping device reduces the clamping force on the belt; when the traction force is less than the minimum value of the threshold range, the first clamping device increases the clamping force on the belt. Based on the above technical solution, this technical solution provides a preferred long-distance, high-slope belt conveyor belt installation system. While using a winch as the traction device, the winch monitors the belt's traction force in real time and transmits the traction force information to the first clamping device in real time. The first clamping device can respond more quickly, achieving automated release of the belt. Simultaneously, using two sets of monitoring and control units allows for more reliable control of the belt release process; that is, the belt traction force monitoring and control unit can be shared with the belt release speed monitoring and control unit, ensuring the safety of belt release from two dimensions.

[0014] A construction method for a long-distance, steep-slope conveyor belt installation system includes the following steps:

[0015] Step 1: Calculate the minimum pressure F required by the first clamping device based on the tunnel slope angle α and elevation difference H, and select the first clamping device appropriately;

[0016] Step 2: Select the appropriate traction device based on the required traction force, rope capacity, and traction speed;

[0017] Step 3: Select a speed sensor based on the traction speed of the traction device;

[0018] Step 4: Setting up the control system: ① When the release speed of the tape exceeds the threshold, the speed sensor sends an electrical signal, instructing the first clamping device to tighten the tape to prevent it from slipping due to excessive release speed; ② Set the threshold range for the traction force of the traction device. When the traction force exceeds the maximum value of the threshold range, the traction device sends an electrical signal, instructing the first clamping device to slowly release the tape to ensure smooth release; when the traction force is less than the minimum value of the threshold range, the traction device sends an electrical signal, instructing the first clamping device to increase the clamping force on the tape to ensure a certain clamping force and prevent the tape from slipping.

[0019] Step 5: Place the roll of tape on the tape release bracket, then let the tape pass through the first clamping device, around the head roller of the conveyor belt, and pull the tape with the traction device to release the tape downwards along the upper idler roller of the conveyor belt. The release speed is controlled by the control system in step 4.

[0020] Step 6: After one roll of tape is released, vulcanize and connect the next roll of tape, move the position of the traction device, and then continue to release the tape;

[0021] Step 7: Repeat steps 4 to 6 until the belt is released to the bottom of the hole. Then install a backstop on the head roller and clamp the lowered belt with the second clamping device to complete the release of the upper belt of the conveyor.

[0022] Step 8: Following steps 4 to 7, release the lower belt of the conveyor until it reaches the bottom of the tunnel;

[0023] Step 9: Vulcanize and connect the upper belt and the lower belt of the conveyor to form a ring at the head of the conveyor and the bottom of the tunnel respectively. Remove the first and second clamping devices, and then tension the belt to complete the belt installation.

[0024] Furthermore, in the first step of the construction method for the installation of conveyor belts on long-distance, steep-slope belt conveyors:

[0025] F=[Hgq0-cLω(q0+ q1)cosα] / μ;

[0026] F—Minimum pressure required by the clamping device, in N;

[0033] q1—Roller rotational mass, kg / m;

[0034] α—Tunnel dip angle;

[0035] μ—the coefficient of friction between the tape and the steel plate, 0.45-0.7.

[0036] Furthermore, in the second step of the construction method for the installation system of a long-distance, steep-slope conveyor belt, when the traction device is a winch, the winch has a traction force of 5t, a rope capacity of 500m, a winch speed of 0.5m / s, and the speed measuring range of the speed sensor is 0-1m / s.

[0037] Furthermore, in the fourth step of the construction method for the installation system of a long-distance, steep-slope conveyor belt, the threshold value of the belt release speed is 0.5 m / s; when a winch is selected as the traction device, the threshold value of the traction force is 1-2 t.

[0038] This invention provides a long-distance, steep-slope conveyor belt installation system and its construction method, which solves the technical problems of difficult installation of conveyor belts in long-distance, steep-slope tunnels, equipment slippage during installation, and belt slippage, ensuring safe and reliable installation of conveyor belts.

[0039] Compared with the prior art, the technical solution of the present invention has the following technical effects:

[0040] 1. To achieve safe, reliable, and efficient installation of belt conveyors.

[0041] 2. Avoid installing tape inside tunnels to reduce the occurrence of safety accidents inside tunnels;

[0042] 3. It eliminates the risk of "slippage" during tape release, ensuring the safety of equipment and personnel.

[0043] 4. The specific application environment of the technical solution of the present invention is in the field of long-distance, steep-slope tunnel construction such as mines, pumped storage, and water diversion projects. The belt conveyor is installed in mine roadways and branch tunnels for transporting materials such as ore and slag.

[0044] 5. The technical solution of the present invention provides a calculation of the tape slippage force, which can reasonably design the clamping device and avoid the tape slipping due to insufficient clamping force;

[0045] 6. The technical solution of the present invention provides two sets of joint control systems for speed and tension, which monitor the tension and speed of the tape during release in real time, and jointly control the clamping device to prevent the tape from slipping off itself as the release length increases;

[0046] 7. The technical solution of the present invention uses a hydraulic clamping device when releasing the tape, which is fast and sensitive and can quickly clamp the tape, making it safer and more reliable than mechanical clamping devices. Attached Figure Description

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the core concept of the present invention and the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Example 1: A belt installation system for a long-distance, steep-slope conveyor belt, such as... Figure 1-Figure 4 As shown, it includes a belt unloading bracket 2 set at the head of the belt conveyor and a traction device 5 set at the lower part of the head of the belt conveyor. That is, the belt unloading bracket 2 is located at the higher part of the slope, while the traction device 5 is located at the lower part of the slope. The specific position of the traction device 5 is selected according to the overall length of the belt conveyor and the amount of belt stored in the belt unloading bracket 2. After a roll of belt is released, the position of the traction device 5 can be moved down.

[0062] A first clamping device 31 is provided between the belt release bracket 2 and the head roller 4 of the belt conveyor to prevent the belt 1 from slipping. During the release of the belt 1, the clamping force of the first clamping device 31 on the belt 1 is adjusted in a timely manner, thereby adjusting the release speed of the belt 1 and the traction force of the traction device 5.

[0063] This technical solution cleverly utilizes the application environment of long-distance, steep-slope belt conveyors. The belt release bracket 2, located at the head of the belt conveyor, can be used to release both the upper and lower belts. Simultaneously, both the upper and lower belts can be released during the descent to the bottom of the tunnel using their own downward weight and the traction force of the traction device 5. Furthermore, the traction device 5 is subjected to the reaction force of the belt 1 pulling upwards, thus avoiding the risk of the belt installation equipment slipping down the slope.

[0064] Meanwhile, a first clamping device 31 is set between the belt release bracket 2 and the head roller 4 of the belt conveyor. This can effectively prevent the belt 1 from slipping and can also adjust the clamping state of the first clamping device 31 in real time according to the release speed of the belt 1 and the traction force of the traction device 5. This provides a suitable speed for the release of the belt 1 and matches the traction force of the traction device 5. Under the premise of convenient installation of the belt 1, the safety of the installation process of the belt 1 is guaranteed, and the performance of the belt 1 is also avoided due to excessive tension.

[0065] Example 2: A belt installation system for a long-distance, steep-slope conveyor belt, such as... Figure 1-Figure 4As shown, it includes a belt unloading bracket 2 set at the head of the belt conveyor and a traction device 5 set at the lower part of the head of the belt conveyor. That is, the belt unloading bracket 2 is located at the higher part of the slope, while the traction device 5 is located at the lower part of the slope. The specific position of the traction device 5 is selected according to the overall length of the belt conveyor and the amount of belt stored in the belt unloading bracket 2. After a roll of belt is released, the position of the traction device 5 can be moved down.

[0066] A first clamping device 31 is provided between the belt release bracket 2 and the head roller 4 of the belt conveyor to prevent the belt 1 from slipping. During the release of the belt 1, the clamping force of the first clamping device 31 on the belt 1 is adjusted in a timely manner, thereby adjusting the release speed of the belt 1 and the traction force of the traction device 5.

[0067] This technical solution also includes a speed sensor 6 for detecting the release speed of the conveyor belt 1. The speed sensor 6 forms a closed-loop control unit with the first clamping device 31 through a control module. When the release speed exceeds a threshold, the first clamping device 31 increases the clamping force on the conveyor belt 1. That is, based on the above embodiment 1, this embodiment provides a preferred long-distance, high-slope conveyor belt installation system. The speed sensor 6 monitors the release speed of the conveyor belt 1 in real time and transmits the release speed information to the first clamping device 31 in real time. The first clamping device 31 can respond more quickly and realize the automated release of the conveyor belt 1.

[0068] Example 3: A long-distance, steep-slope conveyor belt installation system. Based on Example 2, this example further includes a tension sensor for detecting the traction force of the traction device 5. The tension sensor forms a closed-loop control unit with the first clamping device 31 through a control module. When the traction force is greater than the maximum value of the threshold range, the first clamping device 31 reduces the clamping force on the conveyor belt 1. When the traction force is less than the minimum value of the threshold range, the first clamping device 31 increases the clamping force on the conveyor belt 1.

[0069] In this embodiment, a tension sensor is used to monitor the traction force of the tape 1 in real time, and the traction force information is transmitted to the first clamping device 31 in real time. The first clamping device 31 can respond more quickly and realize the automatic release of the tape 1. At the same time, using two sets of monitoring and control units can more reliably control the release process of the tape 1. That is, the monitoring and control unit for the traction force of the tape 1 can be shared with the monitoring and control unit for the release speed of the tape 1, ensuring the safety of the release of the tape 1 from two dimensions.

[0070] Example 4: A long-distance, steep-slope conveyor belt installation system. Based on Examples 1, 2, or 3, this example includes a second clamping device 32 at the head of the conveyor belt. This technical solution provides a preferred long-distance, steep-slope conveyor belt installation system. The second clamping device 32 allows for more reliable positioning of the conveyor belt 1. After the upper and / or lower conveyor belts are released, the second clamping device 32 positions the conveyor belt, after which vulcanization bonding can be performed.

[0071] Example 5 discloses a long-distance, steep-slope conveyor belt installation system. Based on Example 4, the first clamping device 31 is a hydraulic clamping device, and the second clamping device 32 is a mechanical clamping device. Building upon the above technical solutions, this solution provides a preferred long-distance, steep-slope conveyor belt installation system. By employing two clamping devices and using two different clamping methods, the clamping and positioning of the conveyor belt becomes safer and more reliable.

[0072] Example 6: A long-distance, steep-slope conveyor belt installation system. Based on Example 1 or 2, this example sets the traction device 5 as a winch. The winch feeds back the traction force of the conveyor belt 1 to the first clamping device 31 via an electrical signal. When the traction force is greater than the maximum value of the threshold range, the first clamping device 31 reduces the clamping force on the conveyor belt 1. When the traction force is less than the minimum value of the threshold range, the first clamping device 31 increases the clamping force on the conveyor belt 1.

[0073] This technical solution provides a preferred long-distance, steep-slope conveyor belt installation system. While using a winch as the traction device 5, the winch monitors the traction force of the conveyor belt 1 in real time and transmits the traction force information to the first tensioning device 31. The first tensioning device 31 can respond more quickly, achieving automated release of the conveyor belt 1. Simultaneously, using two sets of monitoring and control units allows for more reliable control of the conveyor belt 1 release process; that is, the monitoring and control unit for the traction force of the conveyor belt 1 can be shared with the monitoring and control unit for the release speed of the conveyor belt 1, ensuring the safety of the conveyor belt 1 release from two dimensions.

[0074] Example 7: A construction method for a long-distance, steep-slope conveyor belt installation system, such as... Figure 1-5 As shown, it includes the following steps:

[0075] Step 1: Calculate the minimum pressure F required by the first clamping device 3 based on the tunnel slope angle α and elevation difference H, and select the first clamping device 3 appropriately;

[0077] Step 3: Select speed sensor 6 according to the traction speed of traction device 5;

[0078] Step 4: Setting up the control system: ① When the release speed of tape 1 is greater than the threshold, the speed sensor 6 sends an electrical signal to instruct the first clamping device 3 to tighten tape 1, preventing the tape from slipping due to excessive release speed; ② Setting the threshold range of the traction force of the traction device 5: When the traction force is greater than the maximum value of the threshold range, the traction device 5 sends an electrical signal to instruct the first clamping device 3 to slowly release tape 1, ensuring smooth release of tape 1; When the traction force is less than the minimum value of the threshold range, the traction device 5 sends an electrical signal to instruct the first clamping device 3 to increase the clamping force on tape 1, ensuring tape 1 has a certain clamping force and preventing tape 1 from slipping.

[0079] Step 5: Place the roll of tape 1 on the tape release bracket 2, then let tape 1 pass through the first clamping device 3, around the head roller of the belt conveyor, and pull tape 1 with the traction device 5 to release tape 1 downward along the upper idler roller of the belt conveyor. The release speed is controlled by the control system in step 4.

[0080] Step 6: After one roll of tape is released, vulcanize and connect the next roll of tape, move the position of the traction device 5, and then continue to release the tape;

[0081] Step 7: Repeat steps 4 to 6 until belt 1 is released to the bottom of the hole. Then install a backstop on the head roller and clamp the lowered belt 1 with the second clamping device 32 to complete the release of the upper belt of the conveyor.

[0082] Step 8: Following steps 4 to 7, release the lower belt of the conveyor until it reaches the bottom of the tunnel;

[0083] Step 9: Vulcanize and connect the upper belt and the lower belt of the conveyor to form a ring at the head and bottom of the conveyor respectively. Remove the first clamping device 31 and the second clamping device 32, and then tension the belt to complete the belt installation.

[0084] Example 8: A construction method for a long-distance, steep-slope conveyor belt installation system, based on Example 7, wherein in the first step:

[0093] q1—Roller rotational mass, kg / m;

[0094] α—Tunnel dip angle;

[0095] μ—the coefficient of friction between the tape and the steel plate, 0.45-0.7.

[0096] Example 9: A construction method for a long-distance, steep-slope conveyor belt installation system. Based on Example 8, in the second step, when the traction device 5 selects a winch, the winch's traction force is 5t, the rope capacity is 500m, and the winch speed is 0.5m / s. The speed measurement range of the speed sensor is 0-1m / s.

[0097] Example 10: A construction method for a long-distance, steep-slope conveyor belt installation system.

[0098] Specifically, the control system is configured such that: 1. When the conveyor belt release speed is greater than 0.5 m / s, the speed sensor sends an electrical signal to instruct the hydraulic clamping device to tighten the conveyor belt, preventing it from slipping due to excessive release speed; 2. The winch traction force is set to a range of 1-2 t. When the traction force is greater than 2 t, the winch sends an electrical signal to instruct the hydraulic clamping device to slowly release the conveyor belt, ensuring smooth release; when the traction force is less than 1 t, the winch sends an electrical signal to instruct the hydraulic clamping device to tighten the conveyor belt, providing a certain clamping force to prevent it from slipping.
