Description

Technical Field

[0001] The present invention relates to the technical field of pipe and belt machines, and in particular to a pipe and belt machine. Background Art

[0002] Tubular belt conveyors are widely used in industries such as coal transportation because they can transport materials in a closed manner without flying, spilling, or leaking, thus achieving harmless transportation and a clean environment. However, the transportation route of tubular belt conveyors is long, and the noise problem is particularly prominent in the middle section of the transportation process, which directly affects the lives of the surrounding villagers. The reason why the middle section of the tubular belt conveyor produces noise is mainly because the middle tubular section needs to be supported by a roller group to support the smooth operation of the pipeline and to constrain it to maintain its tubular shape. Therefore, the contact noise between the rollers and the conveying pipeline, the noise generated by the self-rotation of the rollers, and the noise generated by the vibration of the roller brackets will inevitably be the noise sources of the tubular belt conveyor, and the vibration noise of the roller group is the main source of noise in the tubular belt conveyor.

[0003] The roller assembly generally supports the smooth operation of the pipeline through the three lower rollers, and the three upper rollers constrain the conveyor belt to keep it in the tubular shape. However, due to the influence of load, manufacturing errors, installation errors, and failure to replace damaged rollers in time, the following contact conditions may exist between the conveyor belt and the three lower rollers:

[0004] The on-site operating conditions are very complex: 1) three rollers in normal contact; 2) two rollers in contact; and 3) a single roller in contact. Research has shown that the vibration noise is highest when a single roller is in contact, lowest when three rollers are in contact, and second lowest when two rollers are in contact. Therefore, ensuring that multiple rollers are in simultaneous contact directly affects the vibration noise level of the entire roller group.

[0005] At present, the main measures to suppress the vibration noise generated by the friction between the roller and the pipe belt are to design the roller body with some vibration-reducing and noise-reducing materials, or to design the pipe belt with vibration-reducing and noise-reducing materials, or to install vibration-reducing and energy-absorbing devices on the roller. However, the above methods are costly, involve large engineering workloads, and are less practical. Summary of the Invention

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Please refer to Figures 1 to 7 The present invention provides a pipe belt conveyor, comprising: a frame 1, wherein the frame 1 is provided with a mounting hole 10; a pipe belt 2 is inserted into the mounting hole 10; a monitoring assembly 3 is provided on the frame 1 and opposite to the pipe belt 2, and the displacement of the pipe belt 2 in the radial direction of the mounting hole 10 during operation is monitored by the monitoring assembly 3; a plurality of roller assemblies 4 are provided on the frame 1 and arranged around the pipe belt 2, the roller assemblies 4 include rollers 40, and the rollers 40 are movably provided in a direction close to or away from the pipe belt 2, and the positions of the rollers 40 in each roller assembly 4 are adjusted according to the monitoring results of the monitoring assembly 3, so that the surfaces of the rollers 40 in the plurality of roller assemblies 4 are in contact with the pipe belt 2 at the same time.

[0030] The present invention provides a pipe conveyor comprising a frame 1, a pipe conveyor 2, a monitoring assembly 3, and a plurality of roller assemblies 4. The frame 1 is provided with a mounting hole 10, through which the pipe conveyor 2 is inserted. The monitoring assembly 3 is disposed on the frame 1 and opposite the pipe conveyor 2. The monitoring assembly 3 monitors the radial displacement of the pipe conveyor 2 along the mounting hole 10 during operation. The plurality of roller assemblies 4 are disposed on the frame 1 and arranged around the pipe conveyor 2. The roller assemblies 4 include rollers 40 that are movable toward or away from the pipe conveyor 2. The positions of the rollers 40 in each roller assembly 4 are adjusted based on the monitoring results of the monitoring assembly 3 so that the surfaces of the rollers 40 in the plurality of roller assemblies 4 are simultaneously in contact with the pipe conveyor 2. This arrangement allows the positions of the rollers 40 to be adjusted based on the real-time displacement of the pipe conveyor 2 during operation so that the rollers 40 in each roller assembly 4 are in contact with the pipe conveyor 2, thereby ensuring a maximum contact ratio between the rollers 40 and the pipe conveyor 2 and optimizing vibration and noise reduction.

[0031] Specifically, the monitoring assembly 3 includes a buffer seat 30, which is mounted on the frame 1; and a displacement monitoring component 31, which is mounted on the buffer seat 30 and faces the pipe belt 2. The displacement monitoring component 31 monitors the displacement of the pipe belt 2. Preferably, the displacement monitoring component 31 is a displacement laser sensor that monitors the radial changes of the pipe belt 2 along the mounting hole 10 in real time in a non-contact manner.

[0032] In specific implementation, Figure 2 As shown, the buffer seat 30 is provided with a mounting groove 301. The monitoring assembly 3 also includes a damper 32, which is disposed within the mounting groove 301; and a connecting rod 33, the ends of which are respectively connected to the buffer seat 30 and the displacement monitoring component 31. If the buffer seat 30 is directly mounted on the frame 1, the vibration of the frame 1 during the operation of the belt conveyor will affect the measurement value of the displacement laser sensor. Therefore, the damper 32 is installed between the frame 1 and the buffer seat 30 to utilize its vibration-damping effect to reduce the impact of the vibration of the frame 1 on the displacement laser sensor.

[0033] Among them, one end of the damper 32 is adsorbed on the frame 1 through a magnetic component, and the other end is fixed in the installation groove 301 of the buffer seat 30 through a bolt, and then the displacement laser sensor is fixed through the connecting rod 33.

[0034] In a specific implementation, the connecting rod 33 includes a first rod segment 331, a second rod segment 332, and a third rod segment 333, which are sequentially connected. The first rod segment 331 is connected to the buffer seat 30. A first angle is formed between the first rod segment 331 and the second rod segment 332, and a second angle is formed between the second rod segment 332 and the third rod segment 333. The displacement monitoring component 31 is mounted on the third rod segment 333. This not only secures the displacement laser sensor via the connecting rod 33 and the buffer seat 30, but also maintains a certain distance between the displacement laser sensor and the pipe belt 2.

[0035] In the embodiments provided by the present invention, Figure 3 As shown, the roller assembly 4 further includes: a support frame 41, which is provided on the frame 1, and an adjustment portion 42 is provided on the support frame 41. The roller 40 is installed in the adjustment portion 42 and is movably provided along the extension direction of the adjustment portion 42. In this way, the roller 40 is not only fixed by the adjustment portion 42, but also the position of the roller 40 is adjusted by the adjustment portion 42 to ensure that the roller 40 maintains contact with the pipe belt 2.

[0036] Specifically, the support frame 41 includes a mounting plate 410 and an extension plate 411. The mounting plate 410 is connected to the frame 1, and the extension plate 411 extends from the mounting plate 410 toward the pipe belt 2. The adjustment portion 42 is provided on the extension plate 411. Preferably, there are two extension plates 411, which are connected to both ends of the mounting plate 410 and arranged opposite to each other. The ends of the roller 40 are respectively connected to the adjustment portions 42 on the two extension plates 411.

[0037] In a specific implementation, the adjustment portion 42 includes a plurality of adjustment holes 420, which are sequentially arranged along the extension direction of the extension plate 411. Two adjacent adjustment holes 420 are interconnected. The roller 40 is fixed in any one of the plurality of adjustment holes 420 based on the monitoring results of the monitoring assembly 3. This configuration is simple and easy to implement. The distance between the centerlines of the adjustment holes 420 is determined based on the displacement amplitude range of the pipe belt 2.

[0038] In order to fix the roller 40 , the roller assembly 4 further includes: a fixing component 43 detachably connected to the support frame 41 , and a clamping space is provided on the fixing component 43 , and the roller 40 is fixed to the support frame 41 through the fixing component 43 .

[0039] The adjustment portion 42 further includes a fixing hole 421 provided on the extension plate 411 and located to the side of the adjustment hole position 420. Fasteners are sequentially inserted through the fixing member 43 and the fixing hole 421 to secure the roller 40 via the fixing member 43. There are multiple groups of fixing holes 421, each corresponding to each of the adjustment hole positions 420. Preferably, the fixing member is a bolt, and when adjusting the roller 40, the corresponding fixing hole 421 is used to secure the roller 40.

[0040] Preferably, the fixing member 43 includes a first body 430 having a first clearance space 4301 defined therein, and a second body 431 having a second clearance space 4310 defined therein, opposite to the first clearance space 4301, so as to form a clamping space between the first clearance space 4301 and the second clearance space 4310. By dividing the fixing member 43 into the first body 430 and the second body 431, the fixing member 43 is positioned radially along the roller 40, thereby ensuring support rigidity.

[0041] During actual use, before the pipe conveyor is put into operation, the initial value of the pipe belt diameter is calibrated through the monitoring component to determine the initial distance between the roller and the pipe belt; after the pipe belt conveyor is operating normally, the diameter fluctuation value of the pipe belt is monitored by the monitoring component to obtain the maximum diameter change value; based on the maximum diameter change value, the installation posture of the roller is adjusted according to the roller installation posture adjustment device, so as to ensure the maximum contact rate between the roller and the pipe belt and achieve the best vibration reduction and noise reduction effect.

[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0043] The present invention provides a pipe conveyor comprising a frame 1, a pipe conveyor 2, a monitoring assembly 3, and a plurality of roller assemblies 4. The frame 1 is provided with a mounting hole 10, through which the pipe conveyor 2 is inserted. The monitoring assembly 3 is disposed on the frame 1 and opposite the pipe conveyor 2. The monitoring assembly 3 monitors the radial displacement of the pipe conveyor 2 along the mounting hole 10 during operation. The plurality of roller assemblies 4 are disposed on the frame 1 and arranged around the pipe conveyor 2. The roller assemblies 4 include rollers 40 that are movable toward or away from the pipe conveyor 2. The positions of the rollers 40 in each roller assembly 4 are adjusted based on the monitoring results of the monitoring assembly 3 so that the surfaces of the rollers 40 in the plurality of roller assemblies 4 are simultaneously in contact with the pipe conveyor 2. This arrangement allows the positions of the rollers 40 to be adjusted based on the real-time displacement of the pipe conveyor 2 during operation so that the rollers 40 in each roller assembly 4 are in contact with the pipe conveyor 2, thereby ensuring a maximum contact ratio between the rollers 40 and the pipe conveyor 2 and optimizing vibration and noise reduction.
