Technical Field

[0001] This invention relates to the field of testing equipment, and in particular to a comprehensive simulation testing device for belt conveyors. Background Technology

[0002] Belt conveyors are widely used in the logistics field. The speed of belt conveyors is usually tested by using an encoder or by drilling holes in the belt and passing them through detection switches. However, both of these methods have their shortcomings. Encoders are complex and expensive, and drilling holes in the belt and passing them through detection switches can reduce the strength and lifespan of the belt, thus affecting the overall service life of the machine.

[0017] The bottom end of the arc-shaped swing frame is formed with a slot for mounting the first rotating shaft. The first rotating shaft and the pressure roller can be mounted on the lower part of the arc-shaped swing frame through the slot. A second drive cylinder is also obliquely arranged on one side of the second moving platform to drive the arc-shaped swing frame to swing synchronously on its side, thereby driving the first rotating shaft and the pressure roller to press against the belt conveyor.

[0018] The arc-shaped pendulum frame is provided with a limiting ring to further limit the first rotating shaft. The limiting ring is located on the side of the arc-shaped pendulum frame, and the limiting ring passes through both ends of the first rotating shaft.

The first detection mechanism, together with the second detection mechanism, moves above the belt conveyor. At this time, the second detection mechanism moves downward and applies pressure to the belt during the transmission process, thereby increasing the load force when the belt conveyor drives the belt to transmit power. It can also simultaneously test the limit load force when the belt conveyor drives the belt to transmit power under different transport loads. The frictional transmission force generated by the second detection mechanism when testing the belt load is transmitted to the first detection mechanism and generates torque with the first detection mechanism. Thus, the transmission speed when the belt conveyor drives the belt to transmit power under different transport loads can be calculated by testing the torque, and the tension limit value of the belt under different loads can be detected by the tension detection mechanism.

[0037] 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 embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-11In this embodiment of the invention, a comprehensive simulation testing device for belt conveyors includes a workbench 1. A supporting mechanism is provided on one side of the workbench 1, and a belt conveyor 3 to be tested is placed on top of the supporting mechanism. The belt conveyor 3 is equipped with a belt 14 driving above it, and the supporting mechanism clamps the belt conveyor 3 to be tested. On the other side of the workbench 1, a first detection mechanism is provided to detect the speed of the belt conveyor 3 clamped above the supporting mechanism. On the side away from the first detection mechanism, a second detection mechanism is provided to cooperate with it and detect the load on the belt conveyor 3. Furthermore, a tension detection mechanism is provided on the belt conveyor 3 to detect the tension of the belt 14 driving above it. Thus, when the belt conveyor 3 to be tested is placed horizontally above the supporting mechanism, the supporting mechanism detects the speed of the belt conveyor 3 clamped above it. The belt conveyor 3 clamps the belt 14, and simultaneously drives the belt 14 for transmission. The first detection mechanism, along with the second detection mechanism, moves above the belt conveyor 3. At this time, the second detection mechanism moves downward and applies pressure to the belt 14 during transmission, thereby increasing the load force when the belt conveyor 3 drives the belt 14 for transmission. It can also test the ultimate load force of the belt conveyor 3 driving the belt 14 for transmission under different transport loads. The frictional transmission force generated by the second detection mechanism when testing the load on the belt 14 is transmitted to the first detection mechanism and generates torque. By testing the torque, the transmission speed of the belt conveyor 3 driving the belt 14 for transmission under different transport loads can be calculated. At the same time, the tension limit value of the belt 14 under different loads can be detected by the tension detection mechanism.

[0039] The supporting mechanism includes at least three transport platforms 4 laterally slidably disposed on the worktable 1. Slide seats 9 are slidably disposed at both the front and rear ends of each transport platform 4, and clamping blocks 6 are vertically disposed above each slide seat 9 and move synchronously therewith. The slide seats 9 allow the clamping blocks 6 to move horizontally on the transport platform 4. When the belt conveyor 3 is placed on the transport platform 4, the slide seats 9 at both the front and rear ends of the transport platform 4, along with the clamping blocks 6, slide outwards from the center of the transport platform 4, thus forming a space for placing the belt conveyor 3. When the belt conveyor 3 is completely placed inside this space, the slide seats 9 at both the front and rear ends of the transport platform 4, along with the clamping blocks 6, slide towards the center of the transport platform 4. This clamps the belt conveyor 3, preventing positional displacement during inspection and facilitating the clamping of belt conveyors 3 of different types and sizes.

[0040] A second guide rail 8 is provided between the slide 9 and the carrier platform 4, and the second guide rail 8 is laterally located inside the carrier platform 4. The slide 9 is slidably disposed on the second guide rail 8, and the slide 9 and the clamping block move horizontally on the carrier platform 4 through the second guide rail 8.

[0041] A first locking clip 10 is provided on one side of the lower end of the slide block 9 to limit and fix it, and the first locking clip 10 and the slide block 9 are in the same direction of movement. The clamping block 6 is provided with a second locking clip 11 that moves on one side above it, and the second locking clip 11 and the clamping block 6 are in the same direction of movement. The belt conveyor 3 placed between the clamping blocks 6 can be further limited and locked by the second locking clip 11.

[0042] A first guide rail 7 is provided between the transport platform 4 and the workbench 1. The first guide rail 7 is located laterally at the front and rear ends of one side above the workbench 1. The transport platform 4 is mounted horizontally on the first guide rail 7 and slides on the first guide rail 7. A first slider 12 is provided between the transport platform 4 and the first guide rail 7. The first slider 12 is slidably mounted on the first guide rail 7 and slides the transport platform 4 on the first guide rail 7 to adjust the spacing between the transport platforms 4, thereby supporting belt conveyors 3 of different lengths.

[0043] The tension detection mechanism includes a mounting platform 5 mounted on the belt conveyor 3. Above the mounting platform 5, a tension sensor 13 is horizontally positioned to allow the belt 14 to pass through and detect its own tension during transmission. The tension sensor 13 primarily converts belt tension changes into electrical signals through the coordinated action of components such as a tension sensor, a tension support, and a tension wheel. When the belt is taut, it forms a closed loop with the tension wheel, causing strain in the tension sensor. This strain signal is converted into a monitorable electrical signal via a diaphragm resistor and a transmitter. When the belt slacks, a gap appears in the closed loop, the strain in the tension sensor disappears, and the electrical signal changes accordingly. By accurately capturing and analyzing these changes in electrical signals, the belt tension can be monitored in real time, enabling effective monitoring and control of the equipment's operating status.

[0044] The first detection mechanism includes a first movable stage 2 disposed on one side above the workbench 1, and a second detection mechanism disposed on one side below the first movable stage 2. A clutch 18 is disposed on one side above the first movable stage 2, and a torque sensor 16 is disposed on one side of the clutch 18. The torque sensor 16 is located above the first movable stage 2, and a coupling 17 is disposed between the torque sensor 16 and the clutch 18, thereby enabling a transmission connection between the torque sensor 16 and the clutch 18. Furthermore, the input end of the torque sensor 16 is connected to the second detection mechanism for driving. Then, when the first moving platform 2, together with the second detection mechanism, moves above the belt conveyor 3, the second detection mechanism moves downward and presses against the belt 14 being transported on the belt conveyor 3. Since the clutch 18 is in a disengaged state, a torque is generated at the coupling 17, and the torque value is displayed by the torque sensor 16. This torque value is also the tension generated by the belt conveyor 3 under the pressure of the second detection mechanism, thereby testing the tension generated by the belt conveyor 3 when transporting items of different weights, so that the maximum tension of the belt conveyor 3 when transporting items of different weights can be measured later.

[0045] A transmission screw 23 is provided between the second detection mechanism and the torque sensor 16. The transmission screw 23 is located laterally on one side below the first moving platform 2 and passes through the second detection mechanism. The transmission screw 23 is connected to the input end of the torque transmitter 14. A first transmission belt 19 is connected between the transmission screw 23 and the torque sensor 16. The input end of the torque sensor 16 can be rotated when the second detection mechanism is rotated through the cooperation between the transmission screw 23 and the first transmission belt 19.

[0046] A lead screw fixing seat 8 is provided at the connection between the first movable stage 2 and the lead screw 23, and the lead screw fixing seat 8 is located on one side below the first movable stage 2. The lead screw 23 is horizontally supported between the lead screw fixing seats 8, and the lead screw 23 rotates between the lead screw fixing seats 8.

[0047] One end of the transmission screw 23 is provided with a first pulley 22 that rotates synchronously with it, and the first pulley 22 and the first transmission belt 19 are wound together for transmission. A first limiting guide wheel 20 is provided on the side away from the first transmission belt 19 to guide its transmission. The first limiting guide wheel 20 is located on the first moving table 2. The limiting guide wheel 20 ensures that the first transmission belt 19 will not be deviated during transmission.

[0048] On the other side below the first moving stage 2, a second slider 25 and a third slider 26 are arranged in sequence, and the second slider 25 and the third slider 26 slide with the worktable 1 respectively, so that the first moving stage 2 can be moved horizontally on the worktable 1 by means of the second slider 25 and the third slider 26.

[0049] The second testing mechanism includes a second moving platform 15 located vertically below the first moving platform 2 on one side, and arc-shaped swing frames 29 are obliquely arranged on both sides of the second moving platform 15. A first rotating shaft 31 is arranged horizontally below the arc-shaped swing frame 29, and a pressure roller 24 that rotates synchronously with the first rotating shaft 31 is fitted on the outside of the first rotating shaft 31. The arc-shaped swing frame 29 swings on one side of the second moving platform 15, thereby pressing the pressure roller 24 onto the belt conveyor 3. When the pressure roller 24 is fitted onto the first rotating shaft 31 and the first rotating shaft 31 and the pressure roller 24 are fixed below the arc-shaped swing frame 29, the arc-shaped swing frame 29 and the first rotating shaft 31 press the pressure roller 24 onto the belt conveyor 3 and drive the belt conveyor 3 to run. The number of pressure rollers 24 on the first rotating shaft 31 can be placed according to actual needs so that the load-bearing capacity of the belt conveyor 3 under different weights can be tested later.

[0050] A second rotating shaft 34 is provided on one side above the second moving platform 15, which is rotatably engaged with the arc-shaped pendulum frame 29. The second rotating shaft 34 passes through the second moving platform 15, and both ends of the second rotating shaft 34 are rotatably connected to the arc-shaped pendulum frame 29, so that the arc-shaped pendulum frame 29 swings at both ends on one side of the second moving platform 15 through the second rotating shaft 34.

[0051] The bottom end of the arc-shaped swing frame 29 is formed with a slot 36 for mounting the first rotating shaft 31. The first rotating shaft 31 and the pressure roller 24 can be mounted on the lower part of the arc-shaped swing frame 29 through the slot 36. The second moving platform 15 is also provided with a second drive cylinder 30 on one side to drive the arc-shaped swing frame 29 to swing synchronously on its side, thereby driving the first rotating shaft 31 and the pressure roller 24 to press against the belt conveyor 3.

[0052] The arc-shaped pendulum frame 29 is provided with a limiting ring 37 for further limiting the first rotating shaft 31. The limiting ring 37 is located on the side of the arc-shaped pendulum frame 29, and both ends of the first rotating shaft 31 pass through the limiting ring 37. The limiting ring 37 can be fixed to the arc-shaped pendulum frame 29 by bolts so that the first rotating shaft 31 and the pressure roller 24 will not fall out of the slot 36 when they rotate under the arc-shaped pendulum frame 29.

[0053] A first drive shaft 40 is located on the side away from the arc-shaped swing frame 29, and the first drive shaft 40 is laterally located on the side of the second moving platform 15. The first drive shaft 40 rotates on its own axis on the side of the second moving platform 15. A second pulley 38 coaxially driven with the first drive shaft 40 is provided at one end of the first drive shaft 31. A second drive shaft 42 is located on the side away from the first drive shaft 40, and the second drive shaft 42 is laterally located on the side of the second moving platform 15. The second drive shaft 42 rotates on its own axis on the side of the second moving platform 15. The second drive shaft 42 and the drive screw 23 are coaxially connected. The second drive shaft 42 and the first drive shaft 40 are connected by a third drive belt 41, and the first drive shaft 40 and the second pulley 38 are connected by a second drive belt 39. When the pressure roller 24 presses on the belt conveyor 3 and rolls under the action of friction, the driving force generated by friction is transmitted through the synchronous transmission between the first rotating shaft 31, the second drive shaft 42 and the first drive shaft 40, so that the tension of the belt conveyor 3 can be detected later.

[0054] A first drive cylinder 28 is vertically arranged on the other side of the second moving platform 15, and the first drive cylinder 28 drives and connects to a swing arm 27. The swing arm 27 is located obliquely on the other side of the second moving platform 15, and a second limiting guide wheel 35 is rolled at the other end of the swing arm 27. Thus, the first drive cylinder 28 can drive the swing arm 27 and the second limiting guide wheel 35 to press against the belt conveyor 3.

[0055] A fourth slider 32 is provided between the second moving platform 15 and the first moving platform 2. The fourth slider 32 is located horizontally above the second moving platform 15 and is slidably connected to the first moving platform 2. The second moving platform 15 and the fourth slider 32 move in the same direction. Thus, the fourth slider 32 makes the second moving platform 15 stable when sliding on the side below the first moving platform 2.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
