Description

Technical Field

[0001] The invention belongs to the technical field of pipeline transportation, and in particular relates to a pipeline transportation device used in basement construction. Background Art

[0002] In the construction work of the basement, various pipelines will be used, so the pipelines need to be transported at the construction site of the basement. Due to the space limitation of the basement, the pipelines are mostly transported by carts, flatbed trucks and rail carts.

[0003] When using rail trolleys to transport pipelines, due to the complex environment of the construction site, it is easy for foreign objects on the track to block the trolley's forward path. For smaller foreign objects, the trolley can pass directly, but for larger foreign objects, it will cause a greater obstruction to the trolley, which may easily cause collision damage to the trolley, or even cause the trolley to derail and overturn. Even if there are smaller foreign objects, it will cause the trolley to bump and shake when passing through, especially when there is no deceleration. The faster the transportation speed, the greater the bumps and shakes, which can easily cause the pipeline to shift, fall, and even cause safety accidents. Summary of the invention

[0008] In the above-mentioned pipeline transportation device used in basement construction, the driving friction force adjustment mechanism includes a polyaniline conductive polymer coating coated on the outside of the wheel, and the side wall of the wheel is also embedded with a ring-shaped electrical connector electrically connected to the polyaniline conductive polymer coating. The lower end of the trolley body is fixedly provided with an insulating block located on one side of the wheel, and the side wall of the insulating block is embedded with a power supply block arranged in contact with the ring-shaped electrical connector.

[0009] In the above-mentioned pipeline transportation device used in basement construction, the foreign object obstruction monitoring and prompting mechanism includes an extension plate fixedly installed at the front end of the trolley body, and the side wall of the extension plate at one end away from the trolley body is rotatably sleeved with a deflection shaft, one end of the deflection shaft is fixedly connected to the deflection plate, and a torsion spring sleeved outside the deflection shaft is fixedly connected between the deflection plate and the extension plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the set track, trolley body, wheels, pipeline loading mechanism, and load feedback speed control mechanism, the pipeline can be quickly transported in the basement environment, and the weight of the transported pipeline can be automatically weighed and fed back. The transportation speed of the track trolley is automatically adjusted based on the load size of the trolley. The larger the load, the slower the transportation speed, because heavier pipelines will increase the load of the track trolley and put more pressure on the braking system and track. If the speed is too fast, it will lead to excessive braking distance, track damage and the risk of trolley overturning. Automatically adjusting the transportation speed of the pipeline based on the load size of the track trolley can more effectively ensure the transportation safety of the pipeline.

[0014] 2. Through the travel friction adjustment mechanism, inclination sensor, and load feedback speed control mechanism, the slope of the pipeline transportation path can be monitored in real time, and when driving on the slope, the friction coefficient between the wheel and the track can be automatically adjusted. The greater the inclination of the slope, the higher the friction coefficient between the wheel and the track. When the rail trolley is on the slope, the gravity will be decomposed into two separations along the slope direction and perpendicular to the slope direction. The separation along the slope direction will make the rail trolley tend to slide downward. The small friction coefficient between the wheel and the track will cause the sliding force to exceed the friction between the wheel and the track, which will lead to unstable transportation of the rail trolley. The greater the load of the rail trolley, the greater the friction coefficient between the wheel and the track needs to be automatically controlled on the slope with the same inclination angle, so as to better overcome the problem that the gravity component force generated by the rail trolley along the slope direction will affect the stable transportation of the pipeline.

[0015] 3. Through the foreign object obstruction monitoring and prompting mechanism, foreign object size comparison feedback mechanism, and load feedback speed regulation mechanism, it is possible to monitor in real time whether there are foreign objects blocking the track during pipeline transportation. When there are foreign objects, the transportation speed is automatically reduced to reduce the impact force of the collision between the rail trolley and the foreign objects, reduce the risk of damage, and confirm the extent of reducing the transportation speed based on the height size of the foreign object. The larger the height size of the foreign object, the greater the reduction in the transportation speed, which makes the rail trolley more passable. The greater the load of the rail trolley, the greater the reduction in the transportation speed when facing foreign objects of the same size, because the larger the load, the stronger the inertia of the rail trolley, and a slower transportation speed is required to ensure the safety of passage. When the size of the foreign object reaches the threshold, the rail trolley is directly controlled to stop, and an alarm is promptly issued to the staff to remind them to quickly clean up the foreign objects to ensure the stable transportation of the pipeline.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Two sets of foreign object obstruction monitoring and prompting mechanisms 7 are symmetrically fixed on the front side of the trolley body 2 and are arranged corresponding to the position of the track 1. The foreign object obstruction monitoring and prompting mechanism 7 includes an extension plate 71 fixedly installed at the front end of the trolley body 2.

When transporting the pipeline, it is possible to monitor in real time whether there are foreign objects on the track 1 to avoid the problem of the presence of foreign objects affecting the pipeline transportation.

[0023] The foreign body size comparison feedback mechanism 8 is installed on the foreign body obstruction monitoring and prompting mechanism 7. The foreign body size comparison feedback mechanism 8 includes a speed-increasing gear box 81 and a feedback shell 82 fixedly installed outside the extension plate 71. One end of the deflection shaft 72 is fixedly connected to the input end of the speed-increasing gear box 81. The inner wall of the feedback shell 82 is rotatably connected with a transmission screw 83. One end of the transmission screw 83 extends through the feedback shell 82 and is fixedly connected to the output end of the speed-increasing gear box 81. The rod wall of the transmission screw 83 is threadedly sleeved with a transmission seat 84. The inner wall of the feedback shell 82 is fixedly provided with a screw rod 83 arranged parallel to the transmission screw 83.

[0024] The inclination sensor 9 is installed inside the vehicle body 2; The PLC controller 10 is installed inside the trolley body 2, and is electrically connected to the pipeline loading mechanism 4, the load feedback speed regulating mechanism 5, the driving friction force regulating mechanism 6, the foreign matter obstruction monitoring and prompting mechanism 7, the foreign matter size comparison feedback mechanism 8 and the inclination sensor 9 respectively.

[0025] The operating principle of the present invention is described as follows: the pipeline to be transported is placed on the supporting seat 46, and the pipeline is fixed by the rubber band 47. The weight of the pipeline acts on the supporting plate 41, and the supporting plate 41 moves downward along the support column 42 to overcome the elastic force of the load-bearing spring 43. The heavier the pipeline, the greater the distance the supporting plate 41 moves downward. When the pipeline is placed stably, the PLC controller 10 controls the power supply device to supply power to the positioning electromagnetic block 45. The positioning electromagnetic block 45 is energized to generate a magnetic force opposite to the positioning permanent magnetic strip 44, thereby forming a magnetic attraction between the positioning electromagnetic block 45 and the positioning permanent magnetic strip 44, and the supporting plate 41 is firmly fixed and limited, so that the pipeline can also remain stable during subsequent transportation; When the supporting plate 41 moves downward, the transmission rack 51 is driven to move downward synchronously, and the adjusting screw 53 is driven to rotate synchronously through the meshing action of the transmission rack 51 and the transmission gear 54, and then the adjusting screw 53 and the adjusting seat 55 are threadedly connected to each other so that the adjusting seat 55 drives the pressing round head 57 to move synchronously. Specifically, when the supported pipeline is heavier, the supporting plate 41 moves downward by a greater distance, so that the moving distance of the adjusting seat 55 increases synchronously, so that the pressing round head 57 can press and act on the speed regulating switch 56 at the rear side, thereby controlling the trolley body 2 to work at a slower transportation speed to ensure transportation safety; When the trolley body 2 moves to a position with an inclination angle, the inclination sensor 9 feeds back the inclination angle information monitored in real time to the PLC controller 10. The PLC controller 10 controls the power supply device to supply a positive current to the power supply block 64. The power supply block 64 transmits the current to the polyaniline conductive polymer coating 61 through the annular electrical connector 62. Polyaniline is a polymer with good conductivity and electrochemical activity. Under different redox states, the structure and properties of polyaniline will change, thereby affecting its surface roughness and friction coefficient. When a positive current is supplied to the polyaniline conductive polymer coating 61, the polyaniline conductive polymer coating 61 undergoes an oxidation reaction. During the oxidation process, the structure of the polymer molecules changes. More polar groups or cross-linked structures are formed. These structural changes make the surface of the polyaniline conductive polymer coating 61 rougher, thereby increasing the friction coefficient between the wheel 3 and the track 1. Specifically, the greater the inclination angle of the position of the trolley body 2, the PLC controller 10 controls the power supply device to supply a larger current to the polyaniline conductive polymer coating 61. A larger power supply current will make the oxidation reaction of the polyaniline conductive polymer coating 61 faster, making the coating surface rougher, further increasing the friction coefficient between the wheel 3 and the track 1, and ensuring the stability of pipeline transportation, because the greater the inclination angle, the greater the component force of the trolley body 2 along the inclined surface direction, and a greater friction force needs to be provided to ensure the transportation stability of the trolley body 2; When the speed regulating switch 56 on the rear side is triggered by pressing the round head 57, it means that the load of the trolley body 2 is greater. When the friction coefficient of the wheel 3 is adjusted on the slope with the same inclination angle, the PLC controller 10 controls the power supply device to supply a larger current to the polyaniline conductive polymer coating 61, so that the friction coefficient of the wheel 3 is higher. Because the greater the load, the greater the component force of the trolley body 2 along the inclined surface direction, and a greater friction force is required to ensure the transportation stability of the trolley body 2. When the slope inclination angle becomes smaller during the continued movement, the PLC controller 10 controls the power supply device to supply a reverse current to the polyaniline conductive polymer coating 61, so as to promote the reduction reaction of the polyaniline conductive polymer coating 61 and gradually restore the smooth surface, so as to avoid the problem that the excessive friction resistance between the wheel 3 and the track 1 causes excessive loss of both and shortens the service life. When the trolley body 2 is running, the lower end of the deflection plate 73 is always located 1 cm above the upper end of the track 1, and the wheels 3 on the trolley body 2 are in contact with the track 1, and accurate transportation is performed along the track 1. When there is a foreign object on the track 1 at the front end of the running route of the trolley body 2, since the deflection plate 73 is set at the front end of the trolley body 2, the foreign object will first cause the deflection plate 73 to cooperate with the deflection shaft 72 to overcome the action of the torsion spring 74 and deflect, thereby enabling the deflection plate 73 to pass over the foreign object and continue to move forward, The rotating shaft 72 will drive the input end of the speed increasing gear box 81 to rotate, and then drive the transmission screw 83 to rotate through the output end of the speed increasing gear box 81. By adding the speed increasing gear box 81, the small deflection angle of the deflection plate 73 can be expressed with a larger deflection distance. Through the threaded sleeve effect of the transmission screw 83 and the transmission seat 84, the transmission seat 84 drives the feedback conductive contact piece 86 to slide on the feedback resistor rod 85, so that the access resistance value of the feedback resistor rod 85 gradually increases. Specifically, when the height of the foreign body The larger the size, the larger the deflection angle required for the deflection plate 73 to pass over the foreign object, and the feedback conductive contact 86 will slide a larger distance on the feedback resistor rod 85, so that the access resistance of the feedback resistor rod 85 is larger. The feedback conductive contact 86 and the feedback resistor rod 85 will feed back the access resistance signal to the PLC controller 10. When the PLC controller 10 detects that the access resistance of the feedback resistor rod 85 becomes larger, the PLC controller 10 controls the trolley body 2 to decelerate. The larger the access resistance of the feedback resistor rod 85, the larger the height of the foreign object. The greater the reduction in the transportation speed of the trolley body 2 controlled by the PLC controller 10, and the greater the load of the trolley body 2, that is, the more the speed control switch 56 at the rear side is pressed and triggered, when facing the same foreign object, the reduction in the transportation speed needs to be greater, because the larger the load, the stronger the inertia of the trolley body 2, and a slower transportation speed is required to ensure the safety of passing. After the trolley body 2 passes over the foreign object, the normal transportation speed of the trolley body 2 is restored. When the height of the foreign object exceeds the threshold, the trolley body 2 cannot directly pass over the foreign object, and the moving distance of the transmission seat 84 is too large, so that the transmission seat 84 will press on the alarm switch 87. The alarm switch 87 feeds back a signal to the PLC controller 10. The PLC controller 10 controls the trolley body 2 to stop urgently and sends a signal to the staff in time to remind the staff to take corresponding measures for the foreign object.
