Description

Technical Field

[0001] The present invention relates to the technical field of intelligent suspension conveying, in particular to an intelligent suspension conveying system for producing high-purity quartz sand. Background Art

[0002] Suspension conveying is a mechanical conveying method that uses overhead tracks to transport materials. Through the tracks and slings suspended in the air, the materials are automatically transported along the set route. During the production process of high-purity quartz sand, ton bags loaded with high-purity quartz sand are usually connected to the hooks on the suspension conveyor and then transported by the suspension conveyor.

[0003] When the current overhead conveyor is transporting high-purity quartz sand, the sudden acceleration at the moment the overhead conveyor is started will cause the ton bags to shake due to inertia, causing the materials in the ton bags to collide with each other and break, thereby reducing the qualified rate of high-purity quartz sand particles. Continuous shaking will also aggravate the loss of load-bearing structures such as chains, thereby reducing the service life of the overhead conveyor. In addition, the ton bags are easily torn or even fallen off due to shaking, and the dust that floats out can easily cause safety hazards.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to solve the technical problem that the ton bag 49 shakes at the moment when the suspension conveyor 1 is started, Figures 1-12 、 Figure 14 、 Figure 15 、 Figure 18 and Figure 19 As shown, the following preferred technical solutions are provided:

[0039] An intelligent suspension conveying system for high-purity quartz sand production includes a suspension conveyor 1 and a control box 2 installed on one side of the suspension conveyor 1. The suspension conveyor 1 can convey high-purity quartz sand. The control box 2 is provided with a controller for controlling various electrical devices. A fixed column 3 is fixedly connected to the suspension conveyor 1. A rolling assembly is provided on the suspension conveyor 1. The rolling assembly includes a roller, a Y-shaped frame and a mounting plate. The roller is rotatably connected to the Y-shaped frame, and the roller is rollingly connected to the suspension conveyor 1. Figure 2 As shown, the Y-frame is connected to the chain on the suspension conveyor 1, the mounting plate is fixedly connected to the Y-frame, the fixed column 3 is fixedly connected to the mounting plate, and several groups of rolling components are provided. For the convenience of display, it is not shown in the figure. The suspension component 4 is slidably connected inside the fixed column 3, and the outer ring of the fixed column 3 is provided with a clamping component 5. The clamping component 5 is used to clamp the suspension component 4 to fix the position of the suspension component 4 after suspension, thereby avoiding the suspension component 4 from shaking at the moment of starting the suspension conveyor 1. A first limiting component 6 is provided in the clamping component 5. During the process of installing high-purity quartz sand in the suspension component 4, it is not easy to be evenly dispersed in the suspension component 4, and uneven filling will occur, making the four surfaces of the suspension component 4 uneven. During the process of clamping by the clamping component 5, the first limiting component 6 can adaptively adjust the position of the clamping component 5 according to the height of the clamped surface, thereby improving the clamping effect.

[0040] The fixed column 3 is provided with an air suction component 7, which is connected to the support component 8. The support component 8 is connected to the clamping component 5. When the suspension component 4 is unloaded and reset, the air suction component 7 is driven to draw the gas into temporary storage, and in the process of loading the suspension component 4, the air suction component 7 squeezes the temporarily stored gas into the support component 8. Since the suspension component 4 may break during the process of the suspension conveyor 1 transporting the suspension component 4, high-purity quartz sand will be spilled, causing dust to overflow, thereby causing a safety hazard. At the moment of the suspension component 4 breaking, it is detected by the suspension component 4 and the control box 2 cooperates with the support component 8 to rise in time to support the bottom of the suspension component 4, thereby preventing the high-purity quartz sand from spilling. A second limit component 9 is slidably connected to the support component 8. The second limit component 9 is used to limit the position in time during the process of the support component 8 rising, thereby fixing the height of the support component 8 and improving the support effect.

[0041] like Figure 7 and Figure 11As shown, a first reset component 20 is provided in the clamping component 5, and the first reset component 20 is connected to the first limit component 6, and the first reset component 20 is connected to the suspension conveyor 1. The first reset component 20 is used to detect whether the suspension component 4 reaches the unloading position. When the suspension component 4 reaches the unloading position, the first reset component 20 cooperates with the control box 2 to make the first limit component 6 cancel the limit on the clamping component 5. At this time, the clamping component 5 can move freely, thereby facilitating unloading. A second reset component 30 is provided in the support component 8, and the second reset component 30 is connected to the second limit component 9. After the suspension component 4 breaks, when the suspension component 4 reaches the unloading position, the second limit component 9 is driven to move in the support component 8 by the second reset component 30, so that the second limit component 9 cancels the limit on the support component 8, thereby canceling the support of the support component 8 on the bottom of the suspension component 4, which is convenient for unloading.

[0042] like Figure 2-Figure 6 and Figure 12 As shown, the suspension assembly 4 includes a first circular plate 41 slidably connected to the fixed column 3, one side of the first circular plate 41 is fixedly connected to a first spring 42, the other end of the first spring 42 is fixedly connected to the inner wall of the fixed column 3, the outer ring of the first circular plate 41 is evenly provided with four connecting blocks 43, the four connecting blocks 43 are all slidably connected to the fixed column 3, the bottom of the first circular plate 41 is fixedly connected to a connecting rod 44, the connecting rod 44 is slidably connected to the fixed column 3, one end of the connecting rod 44 is fixedly connected to a support plate 45, two tension sensors 46 are installed in the support plate 45, one side of the two tension sensors 46 is fixedly connected to two hooks 47, the two tension sensors 46 are used to detect the tension exerted on the two hooks 47, before use, the tension difference value range of the two tension sensors 46 is set to the reference value range, the tension sensor 46 is an S-type tension sensor, the two hooks 47 are connected to two connecting belts 48, the two connecting belts 48 are both connected to a ton bag 49, and the ton bag 49 is used to load high-purity quartz sand.

[0043] like Figure 2-Figure 9 、 Figure 12 、 Figure 14 and Figure 15 As shown, the clamping assembly 5 includes a connecting ring 51 fixedly connected to the outer ring of the fixed column 3, four connecting blocks 43 are rotatably connected to four rotating plates 52 on one side, four inclined plates 53 are rotatably connected in the connecting ring 51, the four inclined plates 53 are rotatably connected to the four rotating plates 52, four inclined plates 54 are fixedly connected to one side of the four inclined plates 53, the four sliders 54 are slidably connected in four sliding frames 55, four clamping plates 56 are fixedly connected to one side of the four sliding frames 55, the bottom of the four clamping plates 56 are fixedly connected to the first bottom plate 57 and the second bottom plate 58, and the bottom of the ton bag 49 is a short distance away from the first bottom plate 57 and the second bottom plate 58.

[0044] like Figure 7-10 As shown, the first limiting assembly 6 includes a movable plate 61 slidably connected to the sliding frame 55, and several first rotating shafts 62 are rotatably connected to the movable plate 61. One end of the first rotating shaft 62 is fixedly connected to a first wedge block 63, and both ends of the first wedge block 63 are fixedly connected to a first torsion spring 64. The first torsion spring 64 is fixedly connected to the inner wall of the movable plate 61, and both ends of the first wedge block 63 are fixedly connected to a first limiting rod 65. A first limiting groove 66 is provided on the inner wall of the movable plate 61, and the first limiting rod 65 is slidably connected to the first limiting groove 66. The first limiting rod 65 and the first limiting groove 66 are used to limit the rotation of the first wedge block 63. A limiting frame 67 is fixedly connected to the sliding frame 55, and the slider 54 is slidably connected to the limiting frame 67. A second spring 68 is provided on one side of the slider 54, and the other end of the second spring 68 is fixedly connected to the inner wall of the sliding frame 55. The second spring 68 is provided in the limiting frame 67.

[0045] During use, the two connecting belts 48 are connected to the two hooks 47 respectively through external loading equipment. At this time, the ton bag 49 is slowly lowered for hoisting, which is convenient for loading high-purity quartz sand. At the same time, the tension difference value range of the two tension sensors 46 is maintained in the reference value range. The two hooks 47 are affected by the gravity of the ton bag 49, driving the connecting rod 44, the first circular plate 41 and the four connecting blocks 43 to continue to descend, and stretching the first spring 42. During the descent, the two ends of the four rotating plates 52 rotate on the four connecting blocks 43 and the four inclined plates 53 respectively, thereby driving the four inclined plates 53 and the four sliding frames 55 to rotate, so that the four clamping plates 56 clamp the four sides of the ton bag 49. Since the high-purity quartz sand is not easy to be evenly dispersed in the ton bag 49 during the process of being loaded into the ton bag 49, uneven filling will occur. , making the four surfaces of the ton bag 49 uneven. During the clamping process, the four clamping plates 56 are squeezed by the ton bag 49, causing the four sliders 54 to slide in the four sliding frames 55. During the sliding process, the bottom surface of the slider 54 presses down on multiple first wedge blocks 63 inclined surfaces in turn. During the pressing process, the first rotating shaft 62 rotates in the moving plate 61, and the rotation simultaneously stores force for the first torsion spring 64. When the slider 54 slides over the inclined surface of the first wedge block 63, the first torsion spring 64 with stored force resets and drives the first wedge block 63 to reset, so that one side of the slider 54 is in contact with the vertical surface of the first wedge block 63, so that the slider 54 is adjusted to a suitable position, which is convenient for adaptively adjusting the position of the clamping plate 56 according to the extended distance of the clamped surface, thereby improving the clamping effect. During the sliding process, the slider 54 will synchronously squeeze the second spring 68 to store force for the second spring 68.

[0046] In order to solve the technical problem that the connecting belt 48 breaks and causes the high-purity quartz sand to spill out during the transportation of the ton bag 49 by the hanging conveyor 1, Figure 3-Figure 8 and Figures 11-19 As shown, the following preferred technical solutions are provided:

[0047] like Figure 3-Figure 6 、 Figure 12 and Figure 13 As shown, the suction assembly 7 includes a sliding rod 71 fixed to the top of the first circular plate 41, the sliding rod 71 is slidably connected to the fixed column 3, one end of the sliding rod 71 is fixedly connected to the second circular plate 72, a moving groove 73 is provided in the fixed column 3, the second circular plate 72 is slidably connected to the moving groove 73, and two suction rods 74 are relatively connected to the bottom of the second circular plate 72. The two suction rods 74 are both slidably connected to the fixed column 3, and two suction cylinders 75 are relatively provided in the fixed column 3. One end of the two suction rods 74 is fixedly connected to the suction cylinder. The taking plate 76 and the first piston 77 are fixedly connected to one side of the suction plate 76. The outer rings of the suction plate 76 and the first piston 77 are slidably connected to the inner wall of the suction cylinder 75. The bottoms of the two suction cylinders 75 are connected to the air intake pipe 78, and one end of the air intake pipe 78 is connected to a one-way air valve 79. The one-way air valve 79 can facilitate the gas to be sucked into the suction cylinder 75 through the air intake pipe 78, which is convenient for one-way air intake. When the first spring 42 is reset to intake air, the elastic force of the first spring 42 can overcome the resistance of the one-way air valve 79 to achieve air intake.

[0048] like Figure 3-Figure 5 、 Figure 12-16 As shown, the support assembly 8 includes a hose 81 connected to the bottom of the suction cylinder 75, and the other end of the hose 81 is connected to a pressure relief valve 82. When the connecting belt 48 is not broken, the gas pressed into the hose 81 and the hard tube 83 by the suction assembly 7 is higher than the pressure value set by the pressure relief valve 82, the pressure relief valve 82 will discharge the excess gas. A gas storage box 86 is fixedly connected to the second bottom plate 58, and an electronic gas valve 84 is installed at the bottom of the gas storage box 86. The pressure relief valve 82 is connected to the electronic gas valve 84 through the hard tube 83. The electronic gas valve 84 is connected to the gas storage box 86 through the gas outlet pipe 85. A top plate 87 is slidably connected to the gas storage box 86. A second piston 88 is fixedly connected to the bottom of the top plate 87. The second piston 88 is slidably connected to the inner wall of the gas storage box 86. A support seat 89 is fixedly connected to the top of the top plate 87. The electronic gas valve 84 is used to control the gas in the hose 81 and the hard tube 83 to enter the gas storage box 86 through the gas outlet pipe 85, and it is also convenient to discharge the gas in the hose 81, the hard tube 83, the gas outlet pipe 85 and the gas storage box 86.

[0049] like Figure 15-17As shown, the second limiting assembly 9 includes two U-shaped frames 91 that are relatively slidably connected to the support seat 89, and a plurality of second rotating shafts 92 are rotatably connected in the U-shaped frame 91. One end of the second rotating shaft 92 is fixedly connected to a second wedge block 93, and both ends of the second wedge block 93 are fixedly connected to a second torsion spring 94. The other end of the second torsion spring 94 is fixedly connected to the inner wall of the U-shaped frame 91, and both ends of the second wedge block 93 are fixedly connected to a second limiting rod 95. The inner wall of the U-shaped frame 91 is provided with a second limiting groove 96. The second limiting rod 95 is slidably connected to the second limiting groove 96. The second limiting rod 95 and the second limiting groove 96 are used to limit the rotation of the second wedge block 93. Two connecting shafts 97 are rotatably connected on both sides of the air storage box 86. The two connecting shafts 97 are used to slide out the second wedge block 93 to avoid the second wedge block 93 from sliding due to the ton bag 49 pressing the support seat 89, thereby avoiding affecting the reset of the support seat 89. An arc surface 10 is provided on one side of the second wedge block 93 to facilitate the reset of the second wedge block 93.

[0050] During use, the two hooks 47 are acted upon by the gravity of the ton bag 49 to drive the connecting rod 44 and the first circular plate 41 to continuously descend. The first circular plate 41 drives the sliding rod 71, the second circular plate 72, the two suction rods 74, the suction plate 76 and the first piston 77 to continuously descend, squeezing the gas sucked in when the second circular plate 72 is reset, thereby squeezing the gas in the hose 81 and the hard tube 83. When the connecting belt 48 breaks during the transportation of the ton bag 49 by the hanging conveyor 1, the tension difference value range of the two tension sensors 46 exceeds the reference value range. At this time, the tension sensor 46 cooperates with the control box 2 to open the electronic gas valve 84, so that the gas in the hose 81 and the hard tube 83 enters the gas storage box 86 through the outlet pipe 85. , pushing the second piston 88, the top plate 87 and the support seat 89 upward, so that the top of the support seat 89 quickly fits against the bottom of the ton bag 49, which can quickly and conveniently support the ton bag 49 to prevent material from spilling, and at the same time prevent the fracture of the connecting belt 48 from being aggravated. During the upward movement of the support seat 89, multiple second wedge blocks 93 slide out of the support seat 89 in turn. At the moment of sliding out, the stored force second torsion spring 94 resets and drives the second wedge block 93 to reset. The second wedge block 93 drives the second rotating shaft 92 to rotate in the U-shaped frame 91. At the same time, the second limiting rod 95 slides in the second limiting groove 96, so that the horizontal surface of the second wedge block 93 fits against the two connecting shafts 97, which can limit the position of the support seat 89 and improve the supporting effect of the support seat 89.

[0051] like Figure 7 、 Figure 8 and Figure 11As shown, the first reset component 20 includes a position sensor 201 installed in the suspended conveyor 1, and the position sensor 201 is used to detect whether the ton bag 49 is transported to the unloading position. Two first electromagnets 202 are installed on the inner wall of the sliding frame 55, and two first magnet blocks 203 are installed on the bottom of the movable plate 61. A plurality of third springs 204 are fixedly connected to the inner wall of the sliding frame 55, and the other end of the third spring 204 is fixedly connected to the movable plate 61.

[0052] like Figure 14 and Figure 15 As shown, the second reset assembly 30 includes a second electromagnet 301 relatively installed in the support seat 89, a second magnet block 302 is installed on one side of the two U-shaped frames 91, a first moving rod 303 is fixedly connected to one side of the two U-shaped frames 91, the first moving rod 303 is slidably connected to the support seat 89, a fourth spring 304 is fixedly connected to one side of the two U-shaped frames 91, the other end of the fourth spring 304 is fixedly connected to the inner wall of the support seat 89, two second moving rods 305 are fixedly connected to the bottom of the top plate 87, the two second moving rods 305 are slidably connected to the gas storage box 86, a fifth spring 306 is fixedly connected to the bottom of the gas storage box 86, and the other end of the fifth spring 306 is fixedly connected to the second moving rod 305.

[0053] Case 1: When the connecting belt 48 does not break during the conveying process, the position sensor 201 detects that the ton bag 49 is conveyed to the unloading position, and the control box 2 is used to energize the two first electromagnets 202. The first electromagnet 202 attracts the first magnet block 203. At this time, the movable plate 61 slides downward in the sliding frame 55 and squeezes the third spring 204. At this time, the vertical surface of the first wedge block 63 is no longer in contact with the slider 54, so that the slider 54 can move freely, and the ton bag 49 is slowly removed by the external unloading equipment. After the ton bag 49 is removed, the slider 54 is driven to slide in the sliding frame 55 by the reset of the second spring 68, so that the sliding frame 55 and the four clamping plates 56 are reset to facilitate subsequent clamping. The next group of ton bags 49 is convenient for continuous loading. During the unloading process of the ton bags 49, the first spring 42 is reset, driving the first circular plate 41, the connecting block 43, the connecting rod 44, the support plate 45 and the two hooks 47 to rise. During the rising process of the first circular plate 41, the sliding rod 71, the second circular plate 72, the suction rod 74, the suction plate 76 and the first piston 77 are driven to rise, so that the gas enters the suction cylinder 75 through the one-way air valve 79 and the air inlet pipe 78, which is convenient for temporary storage of the gas. When the connecting belt 48 is not broken, if the gas squeezed in the hose 81 and the hard tube 83 is higher than the pressure value set by the pressure relief valve 82, the pressure relief valve 82 will discharge the excess gas, so that the air pressure in the pipeline can push out the support seat 89.

[0054] Case 2: When the connecting belt 48 breaks during the conveying process, the position sensor 201 detects that the ton bag 49 is conveyed to the unloading position, and the external unloading equipment supports the ton bag 49 and cooperates with the control box 2 to open the electronic gas valve 84 to discharge the gas in the hose 81, the hard tube 83, the air outlet pipe 85 and the air storage box 86. The control box 2 simultaneously energizes the second electromagnet 301. At this time, the second electromagnet 301 attracts the second magnet block 302, causing the U-shaped frame 91 to slide in the support seat 89 and squeeze the fourth spring 304. At this time, the horizontal surface of the second wedge block 93 slides on the two connecting shafts 97, causing the second wedge block 93 to slide on the two connecting shafts 97. Block 93 cancels the limit on the support seat 89, so that the bottom of the support seat 89 cancels the support for the bottom of the ton bag 49. At this time, the support seat 89 slides into the gas storage box 86. When the support seat 89 completely enters the gas storage box 86, the control box 2 controls the second electromagnet 301 to cut off the power. At this time, the fourth spring 304 resets, and the arc surface 10 of multiple second wedge blocks 93 squeezes the inner wall of the gas storage box 86, which is convenient for storing force for the second torsion spring 94 for subsequent use. At this time, the two first electromagnets 202 are energized through the control box 2, so that the vertical surface of the first wedge block 63 is no longer in contact with the slider 54, and then the ton bag 49 is removed by external unloading equipment.
