Description

Technical Field

[0001] This invention belongs to the field of belt conveyor dismantling technology, specifically relating to the dismantling device and method for a belt conveyor production line in an extra-long inclined shaft during TBM construction. Background Technology

[0002] During the construction and production of coal mines, sometimes, according to the production plan, the continuous belt conveyor of the main inclined shaft will be dismantled to ensure subsequent production (including the temporary dismantling of the belt after the completion of the inclined shaft construction and the replacement of the old belt during production). Currently, for the dismantling of the continuous belt of the main inclined shaft, the small belt with short distance and light weight is usually dismantled by directly rolling it up with a self-made belt winding machine, while the large belt with long distance and heavy weight is mainly dismantled by using a winch with steel wire rope to drag the entire belt to the ground or by using a crawler-type drive device to pull the belt to the ground.

[0003] Then, a belt winding machine is used to wind and transport the belt away. During dismantling, the upper belt must be dismantled first, followed by the lower belt, and finally the entire belt must be dismantled. Traditional methods for dismantling long-distance large belts in main inclined shafts require the installation of winches or tracked drive devices on the ground, which increases equipment purchase costs and installation time, wastes a lot of manpower and resources, and has low work efficiency, long dismantling period, and poor safety.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a dismantling device and method for a belt conveyor production line in an extra-long inclined shaft of a TBM construction project. It eliminates the need to install additional belt pulling equipment (winches or crawler-type drive devices) on the ground, making full use of the original drive equipment of the belt conveyor production line (main drive roller of the belt conveyor, middle drive roller, and drive roller in the belt storage bin). This achieves significant savings in manpower and resources during dismantling, while also increasing work efficiency, shortening the dismantling period, simplifying the dismantling method, and ensuring the safety of personnel and equipment during the dismantling operation.

Detailed Implementation

[0050] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0051] like Figures 1-2 As shown in the figure, the dismantling device for the TBM construction extra-long inclined shaft belt conveyor production line in one embodiment of the present invention includes a belt conveyor body 1, a belt storage bin 6, an automatic tensioning device 5, a belt winding machine 11, and multiple belt clamping devices. It enables rapid dismantling of the belt conveyor, saving manpower and resources, and ensuring high safety.

[0052] The main body 1 of the belt conveyor includes an upper belt 101, a lower belt 102, a head pulley 103, a tail pulley 15, a middle drive pulley, a main drive pulley 9, and a head unloading pulley 10. A belt storage bin 6 is located at the bottom end face of the main body 1 of the belt conveyor. The belt storage bin 6 is connected to either the upper belt 101 or the lower belt 102 on the main body 1 of the belt conveyor, and is used to temporarily store the belts collected from the main body 1 of the belt conveyor.

[0053] The tail pulley 15 is the tail pulley at a depth of 5300 meters on the belt conveyor.

[0054] like Figures 3-8 As shown, the storage bin 6 includes a front upper belt head 601, a rear belt head 602, and multiple inner drive rollers 603. The front upper belt head 601 is located on the top end face of the storage bin 6, and the rear belt head 602 is located on the bottom end face of the storage bin 6.

[0055] Multiple drive rollers 603 are evenly distributed on the lower end face of the belt conveyor body 1 within multiple storage bins. A pair of opposite end faces of the drive rollers 603 are respectively wound onto the upper belt head 601 on the front side of the storage bin or the belt head 602 on the rear side of the storage bin. In use, the upper belt head 601 on the front side of the storage bin connects to the upper belt 101, facilitating the storage of the upper belt 101 or lower belt 102 into the storage bin 6. The belt head 602 on the rear side of the storage bin connects to a second clamping device 3, which in turn connects to a winding machine 11 to transport the stored upper belt 101 or lower belt 102 from the storage bin 6 to the winding machine 11.

[0056] The automatic tensioning device 5 is located between the lower side of the belt conveyor body 1 and the belt storage bin 6. The automatic tensioning device 5 is connected to one end face of the belt storage bin 6 and can tighten the belt stored in the belt storage bin 6.

[0057] The vulcanizing platform is located on one end face of the storage bin 6. The vulcanizing platform includes a first vulcanizing platform 7 and a second vulcanizing platform 8. The first vulcanizing platform 7 is located on one end face of the storage bin 6, and the second vulcanizing platform 8 is located on one end face of the second clamping device 3.

[0058] The winding machine 11 is located on the front end face of the machine head 103. The winding machine 11 is connected to the belt storage bin 6. It is used to pull out and collect the belts stored in the belt storage bin 6, roll them into a large roll, and then remove the large roll for transport to the destination.

[0059] The multi-channel clamping device is used to secure the belts between the upper belt 101, the lower belt 102, the winding machine 11, and the belt storage bin 6. The multi-channel clamping device includes a first clamping device 2, a second clamping device 3, and a third clamping device 4.

[0060] The first clamping device 2 is located on one side of the belt conveyor body 1 between the automatic tensioning device 5 and the lower belt 102. The first clamping device 2 is used to secure the lower belt.

[0061] The second clamping device 3 is located between the second vulcanizing platform 8 and the main drive roller 9. The second clamping device 3 is connected to the upper belt 101 and is used to secure the upper belt 101.

[0062] The third clamping device 4 is located between the storage bin 6 and the first vulcanizing platform 7. The third clamping device 4 is connected to the belt head 602 on the rear side of the storage bin. The third clamping device 4 is used to secure the belt head 602 on the rear side of the storage bin between the winding machine 11 and the storage bin 6.

[0063] like Figures 8 to 14 As shown, the first clamping device 2, the second clamping device 3, or the third clamping device 4 all include an upper fixed brake beam 201, a lower movable brake beam 202, and a column 203. The lower movable brake beam 202 is located on the bottom end face of the upper fixed brake beam 201, and the column 203 is located on a pair of opposite end faces of the upper fixed brake beam 201 and the lower movable brake beam 202. This achieves the locking and fixing of the belt, and the belt inlet is located on the end faces of the upper fixed brake beam 201 and the lower movable brake beam 202 that are adjacent to each other.

[0064] like Figures 1 to 8 As shown, a simple belt winding device 12 is provided between the first vulcanizing platform 7 and the second vulcanizing platform 8. The simple belt winding device 12 is located between the first vulcanizing platform and the second vulcanizing platform and is used to replace the winch pulling belt.

[0065] A simple winding device 12 is connected to the belt head 602 at the rear of the belt storage bin. The simple winding device 12 is located on the end face opposite to the second clamping device 3. This allows the simple winding device 12 to replace the winch in pulling the belt head 602 at the rear of the belt storage bin 6.

[0066] A first set of three clamping plates 13 is clamped between the belt head 601 on the front side of the belt storage bin and the belt head 602 on the rear side of the belt storage bin. The belt head 601 on the front side of the belt storage bin, which is disconnected from the rear of the belt storage bin 6, is pulled from the top of the belt storage bin 6 to the front of the belt storage bin 6 and reliably connected to the tail of the upper belt 101 cut off on one side of the main drive roller 9 using the first set of three clamping plates 13. This changes the belt between the belt conveyor body 1 and the belt storage bin 6 from entering and exiting from the bottom of the belt storage bin 6 to entering and exiting from the top of the belt storage bin 6.

[0067] The lower belt 102 includes a lower belt head, and a second and third set of clamping plates 14 are clamped between the lower belt head and the upper belt 101. Before the upper belt 101 is completely retracted, when the head of the upper belt 101 reaches the slope change point at the rear of the belt storage bin 6, the upper belt 101 and the head of the lower belt 102, which was previously disconnected at this point, are clamped together using the second and third sets of clamping plates 14.

[0068] like Figures 1-12 As shown, the method for dismantling the conveyor belt in an extra-long inclined shaft of a coal mine using a TBM includes the following steps;

[0069] S1. Disconnect the belt; simultaneously tighten the first clamping device 2, the second clamping device 3 and the third clamping device 4, disconnect the lower belt 102 between the belt storage bin 6 and the automatic tensioning device 5, and disconnect the upper belt 101 between the belt conveyor body 1 and the belt storage bin 6.

[0070] Then, at the tail end of the main body of the belt conveyor 1 at 5300 meters (the lowest part of the inclined shaft), disconnect the upper belt 101 and the lower belt 102;

[0071] S2. Remove the upper belt 101; pull the upper belt head 601, which is disconnected at the rear of the storage bin 6, to the front of the storage bin 6 via the upper part of the storage bin 6, and reliably connect it with the tail of the upper belt 101, which is cut off on one side of the main drive roller 9, using the first and third sets of clamps 13, so that the belt between the main drive roller 9 and the storage bin 6 changes from entering and exiting from the lower part of the storage bin 6 to entering and exiting from the upper part of the storage bin 6;

[0072] The connection method can be referred to as follows: Figure 5 The diagram shows the connection of the first and third sets of clamps 13.

[0073] S3. Modification and test roll of the belt take-up and unwinding system; Pass the belt head 602 of the belt behind the storage bin 6 through the third clamping device 4, pull it through the simple winding device 12, and then pull it out along the lower part of the frame of the second clamping device 3, the main drive roller 9 and the unloading roller 10 of the head, and fix it on the winding machine 11 in front of the unloading roller 10 to complete the modification of the belt take-up and unwinding system; Debug the winding machine and test roll part of the belt;

[0074] The connection between the belt head 602 at the rear of the storage bin and the winding machine 11 can be referred to as follows: Figures 6 to 8 The diagram shown.

[0075] S4. Start taking in the belt (put the belt into the storage bin); First, clamp the third clamping device 4, then open the second clamping device 3, turn on the main drive and middle drive of the belt conveyor body 1, control the speed at about 0.5 m / s, and at the same time turn on the automatic tensioning device 5 to take in the upper belt 101 into the storage bin 6. Since the storage bin 6 currently only has 6 layers of belt, each cycle only needs to take in 300 meters of belt.

[0076] S5. Empty the full storage bin 6; after the upper belt 101 collected in the storage bin 6 causes the storage bin 6 to be full, stop the machine, clamp the second clamping device 3, release the third clamping device 4, and release the belt in the storage bin 6.

[0077] S6. Belt winding and transportation: Use a simple belt winding device to loosen the belt, start the belt winding machine, pull out the belt from the storage bin, and wind it into a large roll; according to the spacing of the original belt vulcanization joint, each 500m roll of belt is cut off and hoisted out for transportation; repeat the above steps to collect the upper layer of belt (leave a portion of the belt as the traction belt when the lower layer of belt is recovered).

[0078] S7. Dismantle the lower belt 102; before the upper belt 101 is completely removed, when the lower end of the upper belt 101 reaches the slope change point at the rear of the storage bin 6, clamp the upper belt 101 and the lower belt 102 that was previously disconnected at this point with the second and third clamping plates 14, and continue to complete the recycling of the lower belt according to the upper belt dismantling process.

[0079] S71: Connection between the lower belt 102 and the upper belt 101; Before the upper belt 101 is finished being retracted, when the head of the upper belt 101 reaches the slope change point at the rear of the storage bin 6, the head of the upper belt 101 and the lower belt 102 that was previously disconnected at this point are clamped together with the second and third clamping plates 14.

[0080] The connection between the upper belt 101 and the belt head of the lower belt 102, which was previously disconnected at this point, can be referred to as follows: Figures 9-10 The diagram shown.

[0081] S72: Start taking in the belt (put the belt into the storage bin); first clamp the third clamping device, then open the second clamping device, start the main drive of the belt conveyor body, and control the speed at about 0.5 m / s; at the same time, start the automatic tensioning device to take in the lower belt into the storage bin.

[0082] S73: Empty the belt storage bin when it is full; after the belt storage bin is full, stop the machine, clamp the second belt clamping device, release the third belt clamping device, and release the belt in the belt storage bin.

[0083] S74: Belt winding and transportation; use a simple winding device to loosen the belt, start the winding machine, pull out the belt from the storage bin, and wind it into a large roll; according to the spacing of the original belt vulcanization joint, each 500m roll of belt is broken and hoisted out for transportation; repeat the above steps until all the lower belts are collected.

[0084] It should be noted that the second clamping device 3 and the third clamping device 4 cannot be opened at the same time, and all clamping devices are in an interlocked state.

[0085] It should be noted that after the upper belt 101 and the lower belt 102 are collected, the intermediate drive device and electrical equipment platform need to be dismantled. The specific dismantling method is as follows;

[0086] S81, Removal of the intermediate drive unit;

[0087] S811. Disconnect the power supply to the equipment and remove the wiring.

[0088] Strictly implement the power outage and restoration ticket system, wear appropriate insulating equipment, disconnect the main power supply, hang a sign and lock the circuit. After 10 minutes, discharge the power first, then test for voltage, remove the main cable and mark the line.

[0089] S812, Disconnect the load-side wiring

[0090] First, discharge the cable, then test for voltage. Once it is confirmed that there is no voltage or current in the line, begin the line dismantling operation. Load the dismantled cable onto a 5T truck and transport it to a designated area on the ground for storage.

[0091] S813, Removal of gearbox and drive drum coupling

[0092] The motor and reducer of the main body 1 of the belt conveyor are connected by a serpentine spring coupling, model 1120T10. To ensure safety and subsequent use, protective measures should be taken during disassembly, and the connection surface should be clean and free of debris.

[0093] S814, Drive Roller and Redirecting Roller

[0094] Remove the intermediate connecting piece of the drive frame and the two rollers. The drive roller and the redirecting roller are the same size and weigh about 4.2 tons. Before removing the bolts, use two 5-ton hand chain hoists to fix them to prevent rolling or slipping. During the process, personnel should not stand on the side that tends to roll.

[0095] S815, removal of drive frame

[0096] The intermediate drive frame consists of four parts: base, inclined support, drive seat, and rollers. Drive roller and The diverting roller consists of a base weighing 2.1 tons x 2, an inclined support weighing 1.3 tons, and a drive seat weighing 5.8 tons (including roller connecting bolts and bolts connecting various components). This component is to be disassembled and transported in separate parts. The inclined support is removed first, followed by the roller base.

[0097] S816, base removal

[0098] Using a 5-ton hand chain hoist, with the anchor point set at the top of the tunnel as the lifting point, the base is lowered into place, and then a double-headed vehicle is used to transport the base to the ground.

[0099] S817, reducer, and motor removal.

[0100] First, remove the anchor bolts. Then, use two 10T hand-operated hoists to lift the motor and reducer. Perform a trial lift first, and then slowly and steadily place the equipment on the double-headed vehicle to transport it to the ground.

[0101] S818, Remove the H-frame, longitudinal beam, straight roller, and idler roller at the center drive position.

[0102] Starting from the upper edge of the central drive excavation chamber, dismantle the equipment along the direction of the wellhead. The dismantled belt H-frames, longitudinal beams, straight rollers, and idlers are neatly placed on the side of the roadway to avoid affecting construction in the work area.

[0103] S819, Removal of Electrical Equipment

[0104] Two 10-ton hand chain hoists are used for the mobile transformer, one 10-ton hand chain hoist is used for the frequency converter, and one 5-ton hand chain hoist is used as the lifting tool for the circulating water cooling device, vacuum power supply switch, and lighting protection system.

[0105] For example, the specific construction process for dismantling a transformer is as follows:

[0106] The transformer was lifted vertically using two 10-ton hand chain hoists and then lifted off the electrical platform via the lifting points. A 5-ton hand chain hoist was then used to horizontally pull the transformer down onto the double-headed vehicle.

[0107] If the transformer is not positioned accurately or needs to be moved, lifting point B can be used as the hoisting point, and a 10-ton hand chain hoist can be used for movement. After the hoisting operation is completed, the hand chain hoist should be promptly returned to the warehouse.

[0108] S820, dismantling of electrical equipment platform

[0109] Due to limited space, the central drive power distribution equipment platform is to be placed above the belt conveyor. The platform is constructed using 100mm×100mm I-beams. To facilitate installation, it is fabricated into three pieces, each 2 meters wide and 6 meters long. After being transported to the well and installed, the platforms are welded and reinforced. The platforms are covered with 5mm thick anti-slip patterned steel plates and equipped with 1.2-meter-high guardrails made of 3cm×3cm square tubing.

[0110] The equipment platform's overhead crane side uses three 6-meter-long, 2.2-meter-high frame legs made of 10# I-beams. These legs are reinforced with 70mm x 70mm angle steel welded together to form a unified frame. The inner side uses 20mm thick steel plates and 10# I-beams to form brackets, which are anchored to the side walls with anchor bolts (a total of 12 brackets). Each bracket uses 2.4-meter-long, 22mm-diameter anchor bolts plus two coils, secured with anchoring agent. The load-bearing steel plate on the side of the bracket must be tightly fitted to the side wall surface, and the anchor bolts must be secured to the load-bearing steel plate using pallets. The equipment platform is then laid flat on the brackets and welded for reinforcement, forming a unified steel structure platform.

[0111] Before dismantling, the electrical platform was disassembled into three 2-meter-wide and 6-meter-long platforms. Using a 5T hand-operated hoist and the overhead anchor cable as the lifting point, the segmented platforms were suspended and transported to the designated location on the ground by a 30T double-headed rubber-wheeled vehicle.

[0112] S82, Main drive unit removal

[0113] The main drive dismantling was carried out in the wellhead area. After the roof was removed, the electrical equipment and drive base were dismantled using a 25t crane in conjunction with human and machine operations. During the construction period, unauthorized personnel were not allowed to enter the work area, and the work permit system was strictly enforced.

[0114] S821. Disconnect the power supply to the equipment and remove the wiring.

[0115] Strictly implement the power outage and restoration ticket system, wear appropriate insulating equipment, disconnect the main power supply, hang a sign and lock the circuit. After 10 minutes, discharge the power first, then test for voltage, remove the main cable and mark the line.

[0116] S822, Disconnect the load-side wiring

[0117] First discharge the cable, then test for voltage. Once you confirm that there is no voltage or current in the line, begin the line dismantling operation. Coil the dismantled cable and store it in the designated area.

[0118] S823, Removal of the two drive rollers and the unloading roller

[0119] The drive roller and the unloading roller are the same size, and each weighs about 4.2 tons. Before removing the bolts, make sure to fix them, use a crane to lift them to prevent them from rolling or slipping. Remove the middle connecting piece of the drive frame and remove the three drive rollers.

[0120] S824, unloading hopper, base bracket, belt frame removal

[0121] The load is disassembled using gas cutting and then lifted out using a crane. Personnel must not climb over guardrails during operations, must wear safety harnesses when climbing, and must not stand under the load during the lifting process.

[0122] S825, two main drive units removed

[0123] Each drive weighs approximately 12 tons. The base bolts connecting the drive base to the drive base are removed by gas cutting, and the vehicle is lifted out by a crane and placed in a designated location. During the lifting process, no one is allowed to stand in the work path area.

[0124] S826, belt frame and idler roller removal

[0125] After the belt and large equipment are dismantled, the belt frame and idlers are dismantled and loaded onto the truck manually.

[0126] Preferably, this application targets the complete dismantling, recycling, and rolling of a belt conveyor model DSJ100 / 56 / 2*630+630, with a total length of 5300m and a slope of 6°.
