Description

Technical Field

[0001] The invention mainly relates to the technical field of conveyor belts, and in particular to a gravity tensioning mechanism deviation correcting device and a processing method thereof. Background Art

[0002] During the operation of conveyor belts in thermal power plants, coal mines and other transportation industries, the gravity tensioning mechanism at the tail of the conveyor belt is unevenly stressed, causing the gravity tensioning mechanism and the track to shift, resulting in accidents such as the gravity tensioning mechanism falling off the track, the conveyor belt running off track, belt wear, and coal spillage.

[0003] Due to various reasons, such as the gravity tensioning mechanism being affected by equipment aging factors, maintenance process factors, human factors, environmental factors, technical level and management level, there are still some unsatisfactory aspects. Especially with the continuous increase in the load operating hours of the generator set, the gravity tensioning mechanism of the coal transportation system of the thermal power plant derails, resulting in equipment shutdown incidents.

[0004] In order to prevent the gravity tensioning mechanism from derailing, it can only be adjusted manually each time, and usually a hand winch is used to force correction. In this way, the driving roller and the driven roller do not have an appropriate amount of loose edge tension, which can easily cause the conveyor belt to slip; secondly, the conveyor belt has no compensation length and other safety hazards, affecting the reliable operation of the equipment. Technical research is carried out on the above-mentioned phenomena such as the gravity tensioning mechanism of the coal transportation system of thermal power plants to improve the equipment management effect. Summary of the invention

[0005] The present invention mainly provides a gravity tensioning mechanism deviation correction device and a processing method thereof to solve the technical problems raised in the above-mentioned background technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A gravity tensioning mechanism deviation correction device, comprising a gravity tensioning roller, wherein locking components are provided on both sides of the gravity tensioning roller, and sliding components are provided at both upper and lower ends of the locking component, and the sides of the two locking components away from the gravity tensioning roller are slidably connected to a slide rail through the sliding components;

[0008] The locking assembly includes a vertical locking rod installed on one side of the gravity tensioning roller through a fixed shaft, a vibration switch mechanism installed on the side surface of the two vertical locking rods close to each other and sleeved on the outside of the fixed shaft, and a fixing seat installed on the upper and lower end surfaces of the vertical locking rods, and an adjustment mechanism is installed on the housing of the fixing seat;

[0009] The sliding assembly includes a fixed block installed inside the fixed seat, a pulley seat installed on a side surface of the fixed block away from the fixed seat, and a horizontal wheel rotatably connected to the pulley seat via a rotating shaft, a magnetic attraction mechanism is provided on the shell of the horizontal wheel, and the horizontal wheel is slidably connected to the slide rail on the same side.

[0010] Furthermore, the adjustment mechanism includes a piston cylinder inserted into the two ends of the fixed seat, and a piston rod inserted into the shell of the piston cylinder, one end of the piston rod extends to the outside and abuts against the fixed block, and the distance between the two piston rods is adjusted by the extension and retraction of the piston rod in the piston cylinder, so that the distance between the two piston rods just adapts to the fixed block, thereby clamping the fixed block.

[0011] Furthermore, the adjustment mechanism also includes a locking groove installed on the end of the piston rod away from the fixed block, a conical locking column inserted into the locking groove, and a neodymium magnet disk installed on the end of the conical locking column away from the locking groove, the neodymium magnet disk is slidably connected to the piston cylinder, and a first electromagnet is provided at the end of the neodymium magnet disk away from the conical locking column, and the first electromagnet is installed on the outer surface of the piston rod. As the part of the conical locking column inserted into the locking groove gradually increases, the piston rod is locked to reduce the movement of the piston rod.

[0012] Furthermore, the adjustment mechanism also includes a push ring arranged inside the piston cylinder and sleeved on the outer surface of the piston rod, and a spring arranged between the push ring and the neodymium magnet disk. The push ring on the outer surface of the piston rod uses the energy stored in the spring between the push ring and the neodymium magnet disk to push the piston rod close to the fixed block, so that the piston rod automatically clamps the fixed block.

[0013] Furthermore, the vibration switch mechanism includes a switch ring that is sleeved on the outside of one end of the fixed shaft and installed on the outer surface of the vertical locking rod, and a plurality of contact switches installed inside the switch ring. When the gravity tensioning roller vibrates, the fixed shaft vibrates, thereby driving the metal contacts installed on the fixed shaft in the contact switch to contact the metal contacts on the inner wall surface of the switch ring.

[0014] Furthermore, two horizontal support rods are installed in sequence from top to bottom between the two vertical locking rods. The two horizontal support rods are symmetrically arranged with the gravity tensioning roller as the central axis. The vertical locking rods are supported by the horizontal support rods between the two vertical locking rods, thereby strengthening the structural strength of the two vertical locking rods.

[0015] Furthermore, the magnetic attraction mechanism includes a conductive slip ring inserted into the rotating shaft housing, and a plurality of second electromagnets connected to the conductive slip rings via wires. The plurality of second electromagnets are arranged on the outer surface of the horizontal wheel. The conductive slip rings are used to prevent the wires connected between the second electromagnets and the power supply from getting entangled when the horizontal wheel rotates, thereby preventing this phenomenon from affecting the use of the second electromagnets.

[0016] According to the above technical solution of a gravity tensioning mechanism correction device, a processing method of a gravity tensioning mechanism correction device is also provided, comprising the following steps:

[0017] Step 1: Process 45# steel to make a horizontal wheel with a size of Φ150mm×50mm and a center hole size of Φ30mm;

[0018] Step 2: Process the 45# steel to make a rotating shaft with a size of Φ30mm×70mm;

[0019] Step 3, processing the Q235A steel plate, so that the Q235A steel plate is cut into two steel plates with a size of 200 mm×150 mm×90 mm and one steel plate with a size of 150 mm×100 mm, the Q235A steel plates are welded to obtain a pulley seat, and a fixing block is welded on the outer surface of the pulley seat;

[0020] Step 4, assembling the horizontal wheel, the rotating shaft and the pulley seat to obtain a sliding assembly;

[0021] Step 5: Insert the fixing block into the fixing seat and connect it with two bolts so that the sliding assembly is installed on the vertical locking rod;

[0022] Step 6: After installing the sliding components on the upper and lower ends of the vertical locking rod in turn, the fixed shaft is fixed to the vertical locking rod by bolts to complete the installation of the gravity tensioning roller.

[0023] Furthermore, the hardness of the horizontal wheel in step one and the rotating shaft in step two are both 58HRC to 62HRC.

[0024] Furthermore, in the step three, when welding between multiple Q235A steel plates and between the pulley seat and the fixed block, the weld is less than or equal to 8 mm.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] Firstly, the present invention can correct the deviation of the gravity tensioning roller, and has the protective function of preventing the gravity tensioning mechanism from derailing and the belt from wearing, thereby reducing the impact of the gravity tensioning mechanism derailing on the coal conveying equipment and improving the utilization efficiency. Specifically, when the gravity tensioning roller moves, the gravity tensioning roller pushes the vertical locking rod to move. Since the horizontal wheel on the vertical locking rod is slidably connected to the slide rail, the moving direction of the gravity tensioning roller is limited, thereby reducing the gravity tensioning roller from derailing.

[0027] Secondly, the present invention can further limit the movement of the horizontal wheel when the gravity tensioning roller swings violently, thereby reducing the swing of the gravity tensioning roller. Specifically, the fixing block is automatically clamped by two piston rods, and after the first electromagnet is energized, the conical locking column is continuously inserted into the locking groove of the piston rod, thereby locking the piston rod, reducing the movement of the piston rod, and limiting the displacement of the horizontal wheel. By energizing the second electromagnet, the horizontal wheel adsorbs the slide rail, reducing the movement of the horizontal wheel, and then reducing the swing amplitude of the gravity tensioning roller.

[0041] For examples, please refer to the attached Figure 1-8 A gravity tensioning mechanism deviation correction device comprises a gravity tensioning roller 10, both sides of the gravity tensioning roller 10 are provided with locking components 20, the upper and lower ends of the locking components 20 are provided with sliding components 30, and the sides of the two locking components 20 away from the gravity tensioning roller 10 are slidably connected with a slide rail 40 through the sliding components 30;

[0042] The locking assembly 20 includes a vertical locking rod 21 installed on one side of the gravity tensioning roller 10 through a fixed shaft 26, a vibration switch mechanism 22 installed on the side surface of the two vertical locking rods 21 close to each other and sleeved on the outside of the fixed shaft 26, and a fixing seat 23 installed on the upper and lower end surfaces of the vertical locking rods 21, and an adjustment mechanism 24 is installed on the housing of the fixing seat 23;

[0043] The sliding assembly 30 includes a fixed block 31 installed inside the fixed seat 23, a pulley seat 32 installed on a side surface of the fixed block 31 away from the fixed seat 23, and a horizontal wheel 33 rotatably connected to the pulley seat 32 via a rotating shaft 35, a magnetic attraction mechanism 34 is provided on the housing of the horizontal wheel 33, and the horizontal wheel 33 is slidably connected to the slide rail 40 on the same side;

[0044] It should be noted that, in this embodiment, since the fixed block 31 and the fixed seat 23 are connected by bolts, the fixed block 31 can be moved, so that workers can adjust the distance between the horizontal wheel 33 and the slide rail 40, and the horizontal wheel 33 is easy to replace, which increases the safety of use, reduces maintenance, is easy to repair, and has a long service life. It can not only improve the working environment and reduce labor intensity, but also save costs and improve work efficiency, and has achieved obvious economic effects.

[0045] For details, please refer to the attached Figure 2 , 5 and 7, the adjustment mechanism 24 includes a piston cylinder 241 inserted at both ends of the fixing seat 23, and a piston rod 242 inserted on the housing of the piston cylinder 241, one end of the piston rod 242 extends to the outside and abuts against the fixing block 31, the adjustment mechanism 24 also includes a locking groove 243 installed at one end of the piston rod 242 away from the fixing block 31, a conical locking column 244 inserted in the locking groove 243, and a conical locking column 244 installed at the locking groove away from the locking groove. A neodymium magnet disk 245 is provided at one end of the piston cylinder 243, the neodymium magnet disk 245 is slidably connected with the piston cylinder 241, a first electromagnet 246 is provided at one end of the neodymium magnet disk 245 away from the conical locking column 244, the first electromagnet 246 is installed on the outer surface of the piston rod 242, the adjustment mechanism 24 also includes a push ring 247 provided inside the piston cylinder 241 and sleeved on the outer surface of the piston rod 242, and a spring 248 provided between the push ring 247 and the neodymium magnet disk 245;

[0046] It should be noted that, in this embodiment, the distance between the two piston rods 242 is adjusted by the extension and retraction of the piston rod 242 in the piston cylinder 241, so that the distance between the two piston rods 242 just fits the fixing block 31, thereby clamping the fixing block 31 and reducing the displacement of the fixing block 31;

[0047] Furthermore, after the first electromagnet 246 is energized, the first electromagnet 246 and the neodymium magnet disk 245 are magnetically repelled, so that the neodymium magnet disk 245 pushes the conical locking column 244 with the repulsive force, so that the conical locking column 244 is continuously inserted into the locking groove 243 of the piston rod 242. In this process, the portion of the conical locking column 244 inserted into the locking groove 243 gradually increases, thereby locking the piston rod 242 and reducing the movement of the piston rod 242.

[0048] Furthermore, the push ring 247 on the outer surface of the piston rod 242 uses the energy stored in the spring 248 between the push ring 247 and the neodymium magnet disk 245 to push the piston rod 242 close to the fixed block 31, so that the piston rod 242 automatically clamps the fixed block 31, and after the first electromagnet 246 is powered off, the energy stored in the spring 248 is used to move the neodymium magnet disk 245 away from the piston rod 242, so that the conical locking column 244 gradually disengages from the locking groove 243, thereby releasing the restriction of the conical locking column 244 on the movement of the piston rod 242, allowing the piston rod 242 to continue to move.

[0049] For details, please refer to the attached Figure 1 , 4 and 6, the vibration switch mechanism 22 includes a switch ring 221 sleeved on the outside of one end of the fixed shaft 26 and installed on the outer surface of the vertical locking rod 21, and a plurality of contact switches 222 installed inside the switch ring 221, two horizontal support rods 25 are installed in sequence from top to bottom between the two vertical locking rods 21, and the two horizontal support rods 25 are symmetrically arranged with the gravity tensioning roller 10 as the central axis, the magnetic attraction mechanism 34 includes a conductive slip ring 341 inserted into the housing of the rotating shaft 35, and a plurality of second electromagnets 342 connected to the conductive slip ring 341 through a wire, and the plurality of second electromagnets 342 are inserted into the outer surface of the horizontal wheel 33;

[0050] It should be noted that, in this embodiment, when the gravity tension roller 10 vibrates, the fixed shaft 26 vibrates, thereby driving the metal contact of the contact switch 222 installed on the fixed shaft 26 to contact the metal contact on the inner wall surface of the switch ring 221, so that the PLC controller connected to the contact switch 222 through a wire receives the electrical signal of the contact switch 222 being turned on, and then energizes the first electromagnet 246 and the second electromagnet 342;

[0051] Furthermore, the horizontal support rod 25 between the two vertical locking rods 21 supports the vertical locking rods 21, thereby strengthening the structural strength of the two vertical locking rods 21;

[0052] Furthermore, the conductive slip ring 341 is used to prevent the wires connected between the second electromagnet 342 and the power supply from getting entangled when the horizontal wheel 33 rotates, thereby preventing this phenomenon from affecting the use of the second electromagnet 342. By energizing the second electromagnet 342, the slide rail 40 is adsorbed to reduce the movement of the horizontal wheel 33.

[0053] like Figure 1-8 As shown, according to the above embodiment, a processing method of a gravity tensioning mechanism correction device is also provided, comprising the following steps:

[0054] Step 1: Process 45# steel to make a horizontal wheel 33 with a size of Φ150mm×50mm and a center hole size of Φ30mm;

[0055] Step 2: Process the 45# steel to make the 45# steel into a rotating shaft 35 with a size of Φ30mm×70mm;

[0056] Step 3: Process the Q235A steel plate, so that the Q235A steel plate is cut into two steel plates with a size of 200 mm×150 mm×90 mm and one steel plate with a size of 150 mm×100 mm, weld the Q235A steel plates to obtain a pulley seat 32, and weld the fixing block 31 on the outer surface of the pulley seat 32;

[0057] Step 4, assembling the horizontal wheel 33, the rotating shaft 35 and the pulley seat 32 to obtain the sliding assembly 30;

[0058] Step 5: insert the fixing block 31 into the fixing seat 23 and connect them with two bolts so that the sliding assembly 30 is installed on the vertical locking rod 21;

[0059] Step 6: After the sliding assembly 30 is installed on the upper and lower ends of the vertical locking rod 21 in sequence, the fixed shaft 26 is fixed to the vertical locking rod 21 by bolts, and the installation of the gravity tensioning roller 10 is completed;

[0060] Furthermore, the hardness of the horizontal wheel 33 in step 1 and the rotating shaft 35 in step 2 are both 58HRC to 62HRC;

[0061] Furthermore, in the step three, when welding between the multiple Q235A steel plates and between the pulley seat 32 and the fixed block 31, the weld seam is less than or equal to 8 mm.

[0062] The specific operation mode of the present invention is as follows:

[0063] When the gravity tension roller 10 is slightly displaced or even violently swung, the gravity tension roller 10 pushes the vertical locking rod 21 to move. Since the horizontal wheel 33 on the vertical locking rod 21 is slidably connected with the slide rail 40, the moving direction of the gravity tension roller 10 is limited, thereby reducing the gravity tension roller 10 from falling off the track.

[0064] When the gravity tension roller 10 vibrates, the fixed shaft 26 vibrates, thereby driving the metal contact of the contact switch 222 installed on the fixed shaft 26 to contact the metal contact on the inner wall surface of the switch ring 221, so that the PLC controller connected to the contact switch 222 through a wire receives the electrical signal of the contact switch 222 being turned on, and then energizes the first electromagnet 246 and the second electromagnet 342;

[0065] The push ring 247 on the outer surface of the piston rod 242 uses the energy stored in the spring 248 between the push ring 247 and the neodymium magnet disk 245 to push the piston rod 242 close to the fixed block 31, so that the piston rod 242 automatically clamps the fixed block 31. After the first electromagnet 246 is energized, the first electromagnet 246 and the neodymium magnet disk 245 are magnetically repelled, so that the neodymium magnet disk 245 uses the repulsive force to push the conical locking column 244, so that the conical locking column 244 is continuously inserted into the locking groove 243 of the piston rod 242. In this process, the portion of the conical locking column 244 inserted into the locking groove 243 gradually increases, thereby locking the piston rod 242 and reducing the movement of the piston rod 242, thereby further limiting the displacement of the horizontal wheel 33 and reducing the swing amplitude of the gravity tension roller 10.

[0066] By energizing the second electromagnet 342 , the horizontal wheel 33 is adsorbed onto the slide rail 40 , reducing the movement of the horizontal wheel 33 , thereby reducing the swing amplitude of the gravity tension roller 10 .

[0067] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
