Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic pipeline logistics transportation, and particularly relates to a pneumatic pipeline obstacle removal mechanism and a pneumatic pipeline logistics system. Background Art

[0002] A pneumatic pipeline transmission system is a system that uses air flow as power to automatically transport items in a closed pipeline. The pneumatic pipeline transmission system mainly consists of the following parts: an air compressor or a centrifugal fan: providing compressed air or negative pressure as a power source. Pneumatic pipelines: a closed pipeline system for guiding and transporting items. A pipeline commutator: controlling the transmission direction. A transmission bottle: loading the items to be transported. A computer control system: monitoring the entire transmission process.

[0003] Generally, the pneumatic pipeline will not get blocked. However, rubber sealing rings are sleeved at both ends of the transmission bottle. If the sealing rings become loose, the transmission bottle is likely to get stuck during transmission and the sealing rings may fall off. This situation is mainly due to the fact that during the long-term operation of the transmission bottle, the sealing rings and the inner wall of the pneumatic pipeline rub against each other to generate heat, and the fallen sealing rings are easily thermally attached to the inner wall of the pneumatic pipeline and are relatively firm. Sometimes, using other transmission bottles to reciprocally impact still cannot remove the fallen sealing rings. Or in the case of other debris blockage, when there is really no other way, it is necessary to use power tools to break open the pneumatic pipeline and manually remove the sealing ring. This process often involves problems such as high-altitude operation, long repair time, and high repair costs.

[0004] In order to overcome the above problems, a pneumatic pipeline obstacle removal mechanism and a pneumatic pipeline logistics system are needed. Summary of the Invention

[0005] The purpose of the present invention is to provide a pneumatic pipeline obstacle removal mechanism and a pneumatic pipeline logistics system, which adopt the method of driving the blockage to rotate by an electric working head, so as to make it break away from the inner wall of the pneumatic pipeline and achieve successful obstacle removal.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A pneumatic pipeline obstacle removal mechanism of the present invention includes:

[0008] A main housing, which is a cylindrical housing structure and is sleeved with a rubber ring on its outer wall, and the outer diameter of the rubber ring is adapted to the inner diameter of the pneumatic pipeline where the blockage needs to be cleaned;

[0009] A reduction motor, which is arranged in the inner cavity of the main housing. A working head is arranged at the output end of the reduction motor. The working head is coaxially arranged with the main housing, and the working head protrudes from the front end of the main housing and can drive the blockage to rotate;

[0010] The reduction motor is electrically connected to the battery compartment or is electrically connected to a power source outside the pneumatic pipeline port through a long cable.

[0011] Furthermore, the working head includes a base plate, a conical head, and a wire brush ring. The disc-shaped base plate is connected to the output end of the reduction motor. The conical head is in the shape of a frustum of a cone with the small end facing forward and is coaxially compounded on the front side wall of the base plate. The wire brush ring is arranged at the outer circle position of the front side wall of the base plate.

[0012] Furthermore, an output shaft head is provided at the output end of the reduction motor. The output shaft head is inserted into the tail hole of the transmission shaft and locked with a pin shaft. The transmission shaft is coaxially mounted in the front opening of the main housing through a bearing. The protruding end of the transmission shaft is connected to the sleeve of the base plate by a flat key and axially locked with a screw.

[0013] Furthermore, a pushing assembly is further included. The pushing assembly is arranged in the inner cavity of the main housing. The reduction motor is installed in the inner cavity of the main housing through a motor sliding seat plate. Guide strips protrude from the periphery of the motor sliding seat plate. Guide slots are axially arranged on the side wall of the inner cavity of the main housing. The guide strips slide in the guide slots. The pushing assembly is arranged in the chamber behind the motor sliding seat plate and can push the motor sliding seat plate.

[0014] Furthermore, the pushing assembly specifically adopts an electric push rod. The electric push rod is electrically connected to the battery compartment, and the electric push rod coaxially pushes the motor sliding seat plate.

[0015] Furthermore, an internal thread step hole is provided at the tail hole of the main housing. The internal thread step hole is threadedly connected with a tail cover, and the battery compartment is installed on the inner side wall of the tail cover.

[0016] Furthermore, an extrusion seat plate is further included. The extrusion seat plate is coaxially arranged between the tail cover and the motor sliding seat plate. The front end face of the extrusion seat plate is connected to the electric push rod. A plurality of claw parts are evenly distributed in a circumferential manner on the periphery of the extrusion seat plate. Guide slots two are axially opened on the inner wall of the main housing at the corresponding positions of the claw parts. The claw parts can slide in the guide slots two. The diameter of the top surface of the guide slots two is larger than the installation ring groove of the rear rubber ring and is communicated with the installation ring groove. The outer wall of the claw part is set as an inclined surface and can push the rear rubber ring outwards.

[0017] Furthermore, a compression spring is further included. The compression spring is coaxially arranged in the inner cavity of the main housing and abuts against the extrusion seat plate and the inner side wall of the tail cover at both ends respectively. The outer diameter of the compression spring is smaller than the diameter of the inner edge of the claw part.

[0018] The present invention also discloses a pneumatic pipeline logistics system, which is equipped with any of the pneumatic pipeline obstacle clearing mechanisms described above to clear the obstructions in the pneumatic pipeline.

[0019] Furthermore, the battery compartment is equipped with a positioning module and a wireless communication module, which is connected to the overall control industrial computer through the wireless communication module; the software part of the industrial computer is provided with a module for controlling the pneumatic pipe obstacle clearing mechanism.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are:

[0021] The pneumatic pipeline obstacle-clearing mechanism and pneumatic pipeline logistics system of the present invention, by installing the working head on a main shell similar to a transmission bottle, can be conveniently transported to the fault point by pneumatic conveying for nearby operations, which reduces the maintenance cost compared to the maintenance method of breaking the pneumatic pipeline; the working head contacts the obstruction and drives the obstruction to rotate, and the forward and reverse reciprocating rotation can loosen the obstruction and achieve the removal of the obstruction. By setting a random battery compartment, it can be convenient to put it in place without being restricted by cables. The pneumatic pipeline obstacle-clearing mechanism of the present invention adopts a method in which an electric working head drives the obstruction to rotate, so that it is separated from the inner wall of the pneumatic pipeline, thereby achieving successful obstacle clearing.

[0022] In addition, through the provision of the cone head, when the blockage is a detached sealing ring, the sealing ring can be centrally propped open so that its large surface contacts the wire brush ring for easy rotation; through the provision of the wire brush ring, the anchoring effect on the sealing ring can be increased, and the torque can be effectively transmitted. By adding a transmission shaft between the reduction motor and the base plate, the bending moment received by the output shaft of the reduction motor can be reduced, and the supporting strength of the working head is increased. By adding the pushing assembly to the inner cavity of the main shell, the working head can be pushed forward while the reduction motor drives the working head to rotate. This pushing can increase the contact force between the working head and the blockage on the one hand, and can also loosen the adhered blockage on the other hand. By adding a detachable tail cover to the tail hole of the main shell, it is convenient to load the internal parts on the one hand, and it is convenient to form a sealing structure to prevent air cross-talk on the other hand. By adding an extrusion seat plate in front of the rear rubber ring, during the ejection process of the electric push rod, the claw part slides backward along the second guide slot, and the inclined outer wall of the claw part pushes the rear rubber ring outward, so that the rubber ring is in close contact with the inner wall of the pneumatic pipe, thereby increasing the holding strength of the pneumatic pipe obstacle clearing mechanism and the inner wall of the pneumatic pipe of the present invention, and avoiding the main shell from retreating backward during the rotation and ejection process of the working head. By adding a compression spring between the extrusion seat plate and the tail cover, the extrusion seat plate can be reset forward when the electric push rod is not ejected, avoiding the shaking of the extrusion seat plate and causing the claw part to impact the rubber ring. The outer circle of the compression spring is limited by the inner edge of the claw part to avoid the compression spring from falling off, and the extrusion seat plate can be limited to the rear by reasonably setting the height of the battery compartment.

[0023] The pneumatic pipeline logistics system of the present invention greatly improves the system's ability to handle blockage failures and reduces risk costs by adding a pneumatic pipeline obstacle clearing mechanism in the pneumatic pipeline logistics system of the present invention. By adding a module to control the pneumatic pipeline obstacle clearing mechanism in the main control software part of the industrial computer, the control is integrated together to facilitate on-site maintenance.

[0034] Embodiment 1

[0035] As Figures 1 to 3 shown, the pneumatic pipeline obstacle clearing mechanism of the present invention includes:

[0036] The main housing 1, which has a cylindrical housing structure and an installation ring groove on the outer wall where a rubber ring 2 is sleeved. The rubber ring 2 is sleeved in the installation ring groove. The outer diameter of the rubber ring 2 is adapted to the inner diameter of the pneumatic pipeline 12 where the blockage 14 needs to be cleared. The rubber ring 2 serves to isolate the gas in front of and behind the main housing 1, ensuring that the pneumatic pipeline obstacle clearing mechanism of the present invention can be conveyed in the pneumatic pipeline 12 like a transfer bottle.

[0037] The reduction motor 5 is arranged in the inner cavity of the main housing 1. The output end of the reduction motor 5 is provided with a working head 7. The working head 7 is coaxially arranged with the main housing 1 and extends out of the front end of the main housing 1. The working head 7 contacts the blockage 14 and can drive the blockage 14 to rotate.

[0038] The reduction motor 5 is electrically connected to the battery compartment 11 or electrically connected to a power source outside the port of the pneumatic pipeline 12 through a long cable. The battery compartment 11 is provided with a battery and an electronic control board. The electronic control board is provided with a wireless communication module for wireless communication with external control equipment.

[0039] By installing the working head 7 on the main housing 1 similar to the transfer bottle, pneumatic conveying can be used to conveniently transport it to the fault point for nearby operation, reducing the maintenance cost compared to the method of breaking open the pneumatic pipeline 12 for maintenance; by bringing the working head 7 into contact with the blockage 14 and driving the blockage 14 to rotate, rotating back and forth, the blockage 14 can be loosened and the blockage 14 can be made to fall off. By providing a random battery compartment 11, it is not restricted by cables and is convenient for positioning. The pneumatic pipeline obstacle removal mechanism of the present invention uses an electric working head to drive the blockage to rotate, so that it disengages from the inner wall of the pneumatic pipeline, achieving successful obstacle removal.

[0040] In a specific embodiment of this embodiment, as Figure 1 and Figure 2 shown, the working head 7 includes a base plate, a tapered head 701, and a wire brush ring 702. The disc-shaped base plate is connected to the output end of the reduction motor 5. The tapered head 701 is in the shape of a truncated cone with the small end facing forward, and the tapered head 701 is made of a powder metallurgy composite material, having good wear resistance. The tapered head 701 is coaxially hot sintered on the front side wall of the base plate. The wire brush ring 702 is arranged at the outer circle position of the front side wall of the base plate. The inner diameter of the wire brush ring 702 is slightly larger than the outer diameter of the large end of the tapered head 701, and the outer diameter of the wire brush ring 702 is smaller than the outer diameter of the main housing 1.

[0041] Specifically, as Figure 2 shown, the wire brush ring 702 adopts the form of a steel needle type brush, which can achieve better anchoring of the blockage 14.

[0042] Through the setting of the tapered head 701, when the blockage 14 is a fallen sealing ring, the sealing ring can be centered and expanded, so that its large surface contacts the wire brush ring 702, facilitating rotation; through the setting of the wire brush ring 702, the anchoring effect on the sealing ring can be increased, effectively transmitting torque.

[0043] In a specific embodiment of this embodiment, as Figure 2 shown, the output end of the reduction motor 5 is provided with an output shaft head 501. The output shaft head 501 is inserted into the tail hole of the transmission shaft 6 and locked with a pin shaft. The transmission shaft 6 is coaxially mounted in the front end opening of the main housing 1 through two radial bearings. The protruding end of the transmission shaft 6 is connected to the sleeve of the base plate by a flat key and axially locked with a screw. Here, the screw needs to use a lock screw.

[0044] Specifically, the outer diameter of the transmission shaft 6 and the inner diameter of the bearing are in clearance fit, and the transmission shaft 6 can axially move relative to the bearing.

[0045] By adding the transmission shaft 6 between the reduction motor 5 and the base plate, the bending moment received by the output shaft of the reduction motor 5 can be reduced, increasing the support strength for the working head 7.

[0046] In a specific implementation manner of this embodiment, as Figure 2 shown, the pneumatic pipeline obstacle clearing mechanism of the present invention further includes a pushing component, and the pushing component is arranged in the inner cavity of the main housing 1. The reduction motor 5 is installed in the inner cavity of the main housing 1 through the motor slide plate 4, and guide bars 401 protrude from the periphery of the motor slide plate 4. A plurality of guide bars 401 are arranged in a circumferentially uniform manner, and guide slots 101 are arranged axially on the inner cavity side wall of the main housing 1. The guide bars 401 slide in the guide slots 101 in a guiding manner. The number of the guide slots 101 and the guide bars 401 is the same and they are arranged in one-to-one correspondence. The pushing component is installed in the chamber behind the motor slide plate 4 and can push the motor slide plate 4.

[0047] Specifically, as Figure 2 shown, the pushing component specifically adopts an electric push rod 8, and the electric push rod 8 is electrically connected to the battery compartment 11. The electric push rod 8 coaxially pushes the motor slide plate 4.

[0048] By adding the pushing component in the inner cavity of the main housing 1, it is possible to push the working head 7 forward while the reduction motor 5 drives the working head 7 to rotate. This pushing can, on the one hand, increase the contact force between the working head 7 and the blockage 14, and on the other hand, can also loosen the adhered blockage 14.

[0049] In a specific implementation manner of this embodiment, as Figure 1 and Figure 2 shown, an internal thread step hole 103 is provided at the tail hole of the main housing 1, and a tail cover 3 is threadedly connected to the internal thread step hole 103. The tail cover 3 seals the rear end of the inner cavity of the main housing 1. The diameter of the tail hole of the main housing 1 is larger than the maximum radial dimension of the motor slide plate 4, so that it can be conveniently inserted forward from the tail hole. The battery compartment 11 is installed on the inner side wall of the tail cover 3 through flange screws.

[0050] Specifically, as Figure 2 shown, a hexagon head hole 301 is provided on the rear end face of the tail cover 3, which is convenient for operators to use an internal hexagon wrench for disassembly and installation.

[0051] By adding a detachable tail cover 3 to the tail hole of the main housing 1, on the one hand, it is convenient to install the internal components, and on the other hand, it is convenient to form a sealing structure to prevent air leakage.

[0052] Specifically, as Figure 2 and Figure 3 shown, Figure 3It is a side view after removing the tail cover 3 from the tail hole of the main housing 1. The pneumatic pipeline obstacle clearing mechanism of the present invention further includes an extrusion seat plate 9, which is also in the cavity of the main housing 1 and is coaxially arranged between the tail cover 3 and the motor slide plate 4. The front end face of the extrusion seat plate 9 is connected to the electric push rod 8. A plurality of claw parts 901 are evenly distributed on the outer circumference of the extrusion seat plate 9. In a specific embodiment, the number of the claw parts 901 is 4. The inner wall of the main housing 1 is axially provided with a second guiding slot 102 at the corresponding position of the claw parts 901, and the claw parts 901 can slide under the guidance of the second guiding slot 102. The claw parts 901 and the second guiding slot 102 are arranged in one-to-one correspondence. The top diameter of the second guiding slot 102 is larger than the bottom diameter of the installation ring groove of the rear rubber ring 2 and is communicated with the installation ring groove. The outer wall of the claw part 901 is set as an inclined surface and can push the rear rubber ring 2 outwards.

[0053] By adding the extrusion seat plate 9 in front of the rear rubber ring 2, during the process of the electric push rod 8 pushing out, the claw parts 901 slide backwards along the second guiding slot 102, and the inclined outer wall of the claw parts 901 pushes the rear rubber ring 2 outwards, so that the rubber ring 2 is tightly attached to the inner wall of the pneumatic pipeline 12, increasing the holding force between the pneumatic pipeline obstacle clearing mechanism of the present invention and the inner wall of the pneumatic pipeline 12, and avoiding the situation that the main housing 1 moves backwards during the rotation and pushing out of the working head 7.

[0054] Specifically, as Figure 2 shown, the pneumatic pipeline obstacle clearing mechanism of the present invention further includes a compression spring 10, which is coaxially arranged in the inner cavity of the main housing 1 and its two ends respectively abut against the inner side walls of the extrusion seat plate 9 and the tail cover 3. The outer diameter of the compression spring 10 is smaller than the diameter of the inner edge of the claw part 901, that is, the inner edge of the claw part 901 limits the outer circle of the compression spring 10.

[0055] Specifically, as Figure 2 shown, the battery compartment 11 is arranged inside the compression spring 10, and the front end face of the battery compartment 11 provides a rear limit for the extrusion seat plate 9 to prevent it from being pushed extremely backwards and damaging the rubber ring 2 or the compression spring 10.

[0056] By adding the compression spring 10 between the extrusion seat plate 9 and the tail cover 3, the extrusion seat plate 9 can be reset forward in the state where the electric push rod 8 is not pushed out, avoiding the impact of the claw part 901 on the rubber ring 2 caused by the shaking of the extrusion seat plate 9. By limiting the outer circle of the compression spring 10 with the inner edge of the claw part 901, the compression spring 10 can be prevented from falling off and the height of the battery compartment 11 can be reasonably set to provide a rear limit for the extrusion seat plate 9.

[0057] Embodiment 2

[0058] The present invention also discloses a pneumatic pipeline logistics system, which is equipped with the pneumatic pipeline obstacle clearing mechanism in any one of the above Embodiment 1 to clean the blockage 14 in the pneumatic pipeline 12.

[0059] By adding a pneumatic pipeline obstacle clearing mechanism in the pneumatic pipeline logistics system of the present invention, the system's ability to cope with blockage failures is greatly improved and the risk cost is reduced.

[0060] In a specific implementation of this embodiment, Figure 4 As shown, the battery compartment 11 is equipped with a positioning module and a wireless communication module, which is connected to the overall control industrial computer 13 through the wireless communication module. The software part of the industrial computer 13 is provided with a module for controlling the pneumatic pipeline clearing mechanism, that is, it can monitor the pneumatic pipeline clearing mechanism to clear the blockage 14.

[0061] By adding a module for controlling the pneumatic pipeline obstacle clearing mechanism to the main control software part of the industrial computer 13, the modules are integrated together for control, which is convenient for operation during on-site maintenance.

[0062] The pneumatic pipeline logistics system obstacle clearing process of the present invention: when the pneumatic pipeline 12 is blocked by the blockage 14 and the blockage 14 cannot be pushed out by the ordinary transmission bottle, the blockage 14 is generally a rubber sealing ring that has fallen off. The pneumatic pipeline obstacle clearing mechanism is activated and placed at the feeding port of the pneumatic pipeline 12, and the working head 7 is facing upward. The module corresponding to the obstacle clearing is controlled on the touch screen of the industrial computer 13, the air compressor is started, and negative pressure is generated in the pneumatic pipeline 12. The pneumatic pipeline obstacle clearing mechanism enters the pneumatic pipeline 12 and is transported along the pipeline to the blockage 14 and is blocked. At this time, the position of the main housing 1 can be observed on the touch screen according to the signal sent back by the positioning module in the battery compartment 11. The operator controls the button on the touch screen, and the electric control board in the battery compartment 11 supplies power to the reduction motor 5, the reduction motor 5 starts, and the working head 7 starts to rotate through the transmission shaft 6. Then the button is operated, and the electric control board in the battery compartment 11 supplies power to the electric push rod 8, and the electric push rod 8 is pushed out. The electric push rod 8 pushes the extrusion seat plate 9 backward, and the claw part 901 slides backward along the guide slot 102. The outer wall of the inclined surface of the claw part 901 pushes the rear rubber ring 2 outward, so that the rubber ring 2 is fully attached to the inner wall of the pneumatic pipe 12 at four points, increasing the holding force of the pneumatic pipe obstacle removal mechanism of the present invention and the inner wall of the pneumatic pipe 12. At the same time, the electric push rod 8 pushes the motor slide plate 4 forward, and the motor slide plate 4 drives the reduction motor 5, the transmission shaft 6 and the working head 7 to move forward. During the rotation of the cone head 701 of the working head 7, the sealing ring of the blockage can be centrally opened, so that its large surface contacts the wire brush ring 702. The steel needle of the wire brush ring 702 anchors the sealing ring, effectively transmits torque, drives the sealing ring to rotate, and separates it from the inner wall of the pneumatic pipe 12. In this process, the operation mode of the reduction motor 5 can be selected to run in forward and reverse intervals, which has a better loosening effect. After the obstruction sealing ring is separated from the inner wall of the pneumatic pipe 12, the pneumatic pipe obstacle clearing mechanism carries the obstruction sealing ring and unloads it from the outlet of the pneumatic pipe 12 under the negative pressure of the pneumatic pipe 12, thereby completing the obstacle clearing work.

[0063] In summary, for the pneumatic pipeline obstacle removal mechanism of the present invention, by installing the working head 7 on the main housing 1 similar to the transmission bottle, pneumatic conveying can be used to conveniently transport it to the fault point for nearby operation, reducing the maintenance cost compared with the way of breaking the pneumatic pipeline 12 for maintenance; by bringing the working head 7 into contact with the blockage 14 and driving the blockage 14 to rotate, rotating back and forth, the blockage 14 can be loosened and the blockage 14 can be made to fall off. By providing a random battery compartment 11, it can be in place conveniently without being restricted by cables. For the pneumatic pipeline obstacle removal mechanism of the present invention, the method of using an electric working head to drive the blockage to rotate is adopted to make it break away from the inner wall of the pneumatic pipeline and achieve successful obstacle removal. In addition, through the setting of the conical head 701, when the blockage 14 is a fallen sealing ring, the sealing ring can be centered and expanded, so that its large surface contacts the wire brush ring 702, facilitating rotation; through the setting of the wire brush ring 702, the anchoring effect on the sealing ring can be increased, effectively transmitting torque. By adding a transmission shaft 6 between the reduction motor 5 and the base plate, the bending moment received by the output shaft of the reduction motor 5 can be reduced, increasing the support strength for the working head 7. By adding the pushing assembly in the inner cavity of the main housing 1, the working head 7 can be pushed forward while the reduction motor 5 drives the working head 7 to rotate. This pushing can increase the contact force between the working head 7 and the blockage 14 on the one hand, and can also push and loosen the adhered blockage 14 on the other hand. By adding a detachable end cap 3 to the tail hole of the main housing 1, it is convenient to install the internal components on the one hand, and it is convenient to form a sealing structure to prevent air leakage on the other hand. By adding an extrusion seat plate 9 in front of the rear rubber ring 2, during the ejection process of the electric push rod 8, the claw part 901 slides backward along the guide slot two 102, and the outer wall of the inclined surface of the claw part 901 pushes the rear rubber ring 2 outward, so that the rubber ring 2 is in close contact with the inner wall of the pneumatic pipeline 12, increasing the gripping force between the pneumatic pipeline obstacle removal mechanism of the present invention and the inner wall of the pneumatic pipeline 12, and avoiding the situation that the main housing 1 moves backward during the rotation and ejection of the working head 7. By adding a compression spring 10 between the extrusion seat plate 9 and the end cap 3, the extrusion seat plate 9 can be reset forward in the state where the electric push rod 8 is not ejected, avoiding the impact of the claw part 901 on the rubber ring 2 caused by the shaking of the extrusion seat plate 9. By limiting the outer circle of the compression spring 10 by the inner edge of the claw part 901, the compression spring 10 can be prevented from falling off, and by reasonably setting the height of the battery compartment 11, the extrusion seat plate 9 can be limited at the rear.

[0064] For the pneumatic pipeline logistics system of the present invention, by adding a pneumatic pipeline obstacle removal mechanism to the pneumatic pipeline logistics system of the present invention, the processing ability of the system to cope with blockage faults is greatly improved, and the risk cost is reduced. By adding a module for controlling the pneumatic pipeline obstacle removal mechanism to the main control software part of the industrial control computer 13 and integrating them for control, it is convenient to operate during on-site maintenance.
