It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 5, a multi-functional pipe inner wall processing apparatus according to the present invention will now be described. The multifunctional pipe inner wall processing equipment comprises a running track 10, a walking platform 20, an operating platform 30, a grinding rod 40 and a wind rod 50, wherein the grinding rod 40 and the wind rod 50 are selected from the working side of the operating platform 30, and the walking platform 20 is arranged on the running track 10 and can move along the running track 10; the operation platform 30 is arranged on the walking platform 20, a first motor 31 and an air duct hole 32 are arranged on the operation platform 30, the air duct hole 32 is used for being connected with an air source, and a working side is formed on one side, facing the nodular cast iron pipe, of the operation platform 30; when the grinding rod 40 is arranged on the operating platform 30, the grinding rod 40 is in transmission connection with the first motor 31, and the first motor 31 drives the grinding rod 40 to rotate; when the air bar 50 is mounted on the console 30, the air bar 50 is communicated with the air duct holes 32, and the air duct holes 32 are used for supplying air to the air bar 50.
It should be noted that the grinding rod 40 mainly achieves a grinding effect, and therefore the grinding rod 40 can be a solid rod, so that the grinding strength is ensured; the air bar 50 is primarily responsible for the purging action, and therefore the air bar 50 is a hollow bar, thereby ensuring the passage of the purge gas.
When the multifunctional pipe inner wall processing equipment provided by the embodiment is used, the running track 10 is installed, and the position of the nodular cast iron pipe is adjusted, so that the axial direction of the nodular cast iron pipe is parallel to the running track 10; when the position of the nodular cast iron pipe is fixed, firstly, a polishing step is carried out, the polishing rod 40 is fixed on the operation table 30 at the moment, the first motor 31 on the operation table 30 is in transmission connection with the polishing rod 40, after the polishing rod 40 is fixed, the walking platform 20 and the first motor 31 are synchronously started, the walking platform 20 is used for walking towards the direction of the nodular cast iron pipe, the first motor 31 is used for driving the polishing rod 40 to rotate, when the polishing rod 40 extends into the inner wall of the nodular cast iron pipe, the nodular cast iron pipe is polished, at the moment, special equipment drives the nodular cast iron pipe to rotate, and when the polishing rod 40 runs for a certain distance in the nodular cast iron pipe, the nodular cast iron pipe is polished; after polishing is completed, the first motor 31 is turned off, the walking platform 20 drives the polishing rod 40 to withdraw from the nodular cast iron pipe (i.e. to move away from the nodular cast iron pipe), the polishing rod 40 is disassembled and the air feeding rod 50 is installed in a replacement mode, at the moment, the first motor 31 is idle, the air pipe hole 32 is communicated with the air feeding rod 50 and used for continuously supplying air to the air feeding rod 50, and the walking platform 20 moves according to the path to complete the purging process.
It should be understood that the first motor 31 is in transmission connection with the grinding rod 40 through the belt 33, a first belt pulley is arranged on an output shaft of the first motor 31, a second belt pulley is arranged at the end part of the grinding rod 40, and the first belt pulley and the second belt pulley are in transmission through the belt 33; optionally, the diameter of the second pulley is smaller than that of the first pulley, so that the rotation speed of the grinding rod 40 is ensured under the condition that the rotation speed of the first motor 31 is relatively small, the rotation speed of the first motor 31 is reduced, and energy conservation and consumption reduction are achieved.
Compared with the prior art, the multifunctional pipe inner wall processing equipment limits the walking path of the walking platform 20 through the matching of the walking platform 20 and the running track 10, prevents the grinding error caused by the deviation of the route, and improves the grinding quality and the quality of the nodular cast iron pipe; wherein, the operation table 30 can be simultaneously provided with a grinding rod 40 and a wind rod 50, and when the grinding rod 40 works, the first motor 31 works; the air duct 50 is communicated with the air duct hole 32 when working, the first motor 31 does not influence the working of the air duct 50, so that the equipment can realize two working states (grinding and purging) simultaneously only by replacing the grinding rod 40 and the air duct 50, the equipment does not need to be frequently replaced, the processing efficiency is improved, the capital investment is reduced, and the occupation of space is reduced.
In some embodiments, the track 10 may be configured as shown in fig. 1 and 4. Referring to fig. 1 and 4, a first limiting block 11 is arranged at one end of the running track 10 close to the ductile cast iron pipe, a second limiting block 12 is arranged at one end far away from the ductile cast iron pipe, a third limiting block 13 positioned between the first limiting block 11 and the second limiting block 12 is further arranged on the running track 10, and the third limiting block 13 is detachably connected with the running track 10; when the polishing rod 40 is installed on the operating table 30, the path between the second limiting block 12 and the third limiting block 13 is the walking path of the polishing rod 40; when the wind lever 50 is mounted on the console 30, a path between the first stopper 11 and the second stopper 12 is a traveling path of the wind lever 50.
When grinding is carried out, only part of the inner wall of the nodular cast iron pipe needs to be ground, so that the traveling path between the second limiting block 12 and the third limiting block 13 is the length of the section of the inner wall of the nodular cast iron pipe which needs to be ground; however, when purging, the chips generated by grinding need to be blown out of the nodular cast iron pipe, so the traveling path between the first stopper 11 and the second stopper 12 is at least equal to the length of the nodular cast iron pipe. When the wind lever 50 works, the third limiting block 13 is not installed, and the walking path of the walking platform 20 can be automatically limited under different working states by arranging the first limiting block 11, the second limiting block 12 and the third limiting block 13, so that manual control is reduced, the deviation of the moving distance of the manual control is prevented, and the quality of the nodular cast iron pipe is improved.
As another use condition, the third limiting block 13 can be detached and can be mounted at different positions on the running track 10 when the third limiting block 13 is mounted, so that the distance between the second limiting block 12 and the third limiting block 13 is changed to adapt to different grinding lengths.
In some embodiments, the third stopper 13 may adopt a structure as shown in fig. 1 and fig. 3. Referring to fig. 1 and 3, the third stopper 13 includes a card and portion 14 and a stopper portion 15, and the card and portion 14 has an opening that can be opened and closed and is used to be clamped on the periphery of the running rail 10; the position limiting part 15 is fixedly arranged on the top of the card and part 14. Alternatively, the catch portion 14 is similar to a catch structure having two pivotally connected arcuate segments and a spring connected between the two arcuate segments, the spring having a biasing force urging the two arcuate segments toward one another. Therefore, the opening can be driven by external force to be opened and taken down, the arc piece is close to the outer side of the running track 10 when the external force is loosened, the third limiting block 13 is convenient to detach and install, the position of the third limiting block 13 is convenient to change, and the labor intensity is reduced.
In some embodiments, the structure shown in fig. 1 and 4 may be adopted to realize the automatic start and stop of the walking platform 20. Referring to fig. 1 and 4, a traveling roller 21 matched with the running track 10 is arranged at the bottom of the traveling platform 20, and a second motor 22 for driving the traveling roller 21 to rotate is further arranged on the traveling platform 20; the first limiting block 11, the second limiting block 12 and the third limiting block 13 are all provided with an inductor 16, and the inductor 16 is in communication connection with the second motor 22. Optionally, the sensor 16 is a pressure sensor 16.
When the grinding rod 40 works: the second motor 22 is started, the walking roller 21 starts to roll from the position of the second limiting block 12 towards the third limiting block 13, when the walking roller 21 contacts the third limiting block 13, pressure is applied to the sensor 16 on the third limiting block 13, the sensor 16 on the third limiting block 13 sends a backspacing signal, the second motor 22 controls the walking roller 21 to backspace and roll towards the direction of the second limiting block 12, when the walking roller 21 contacts the second limiting block 12, pressure is applied to the sensor 16 on the second limiting block 12, the sensor 16 on the second limiting block 12 sends a stop signal, the second motor 22 stops, and the walking roller 21 stops rotating.
When the wind lever 50 is operated: the third limiting block 13 is in a detached state, the second motor 22 is started, the walking roller 21 starts to roll from the position of the second limiting block 12 towards the first limiting block 11, when the walking roller 21 contacts the first limiting block 11, pressure is applied to the sensor 16 on the first limiting block 11, the sensor 16 of the first limiting block 11 sends a backing signal, the second motor 22 controls the walking roller 21 to roll back towards the direction of the second limiting block 12, when the walking roller 21 contacts the second limiting block 12, pressure is applied to the sensor 16 on the second limiting block 12, the sensor 16 on the second limiting block 12 sends a stop signal, the second motor 22 stops, and the walking roller 21 stops rotating.
The sensors 16 are respectively arranged on the first limiting block 11, the second limiting block 12 and the third limiting block 13, so that the running process of the walking platform 20 in different working states can be controlled, manual control is replaced, manual operation is reduced, and the operation process is simplified; and the walking state of the walking platform 20 can be quickly changed by controlling the sensor 16, so that the reaction is timely and the working hours are reduced.
In some embodiments, to improve the stability of the grinding rod 40 and the wind bar 50, a structure as shown in fig. 1 and 4 may be used. Referring to fig. 1 and 4, the walking platform 20 is further provided with a guide sleeve 60, and the guide sleeve 60 can be annularly arranged outside the grinding rod 40 or the wind rod 50. When the grinding rod 40 works, the first motor 31 drives the grinding rod 40 to rotate, and as the grinding rod 40 needs to extend into the nodular cast iron pipe, the grinding rod 40 needs to meet a certain length, and under the condition that the guide sleeve 60 is arranged, the grinding rod 40 can be stabilized within the range of the guide sleeve 60, so that the grinding rod 40 is prevented from shaking due to overlong length in the working process to influence the grinding quality (in the state, the grinding rod 40 is in rotating fit with the guide sleeve 60); when the air rod 50 works, the air pipe hole 32 supplies air to the air rod 50, in order to ensure the blowing strength, the impulsive force of an air source needs to meet certain pressure, and under the condition that the guide sleeve 60 is arranged, the air rod 50 can be stabilized within the range of the guide sleeve 60, and the air rod 50 is prevented from moving when the air rod 50 works (the air rod 50 and the guide sleeve 60 are clamped in the state).
Therefore, the guide sleeve 60 not only facilitates installation of the polishing rod 40 or the wind rod 50, but also can play a stabilizing role in working of the polishing rod 40 and the wind rod 50, and work quality is guaranteed.
In some embodiments, the guide sleeve 60 may be fixed as shown in fig. 3. Referring to fig. 3, the bottom of the guide sleeve 60 is uniformly provided with a plurality of fixing seats 61 along the axial direction thereof, each fixing seat 61 comprises a connecting plate 62 and a connecting rod 63, each connecting rod 63 is connected to the traveling platform 20 through a threaded connection, and each connecting rod 63 is connected between the guide sleeve 60 and the corresponding connecting plate 62. Wherein, all can adopt the welded mode to be connected between connecting rod 63 and the connecting rod 63, between connecting rod 63 and the guide sleeve 60, it is fixed firm. Guide sleeve 60 needs to reduce the rocking of pole 40 and the wind pole 50 of polishing respectively, through setting up fixing base 61, improves guide sleeve 60's joint strength, prolongs guide sleeve 60's life.
Alternatively, the installation height of the guide sleeve 60 may be changed by changing the length of the connecting rod 63, thereby using the installation of the grinding rod 40 and the wind lever 50.
In some embodiments, the grinding rod 40 and the guide sleeve 60 may be configured as shown in FIG. 3. Referring to fig. 3, when the grinding rod 40 is installed, the multifunctional pipe inner wall processing apparatus further includes a rolling bearing 64, and the rolling bearing 64 is disposed between the guide sleeve 60 and the grinding rod 40 to reduce the relative friction between the guide sleeve 60 and the grinding rod 40. Because the grinding rod 40 and the guide sleeve 60 need to be connected in a rolling manner, the rolling bearing 64 is arranged, so that the influence of friction on the grinding rod 40 can be reduced, the smoothness of the grinding rod 40 is improved, the damage to the grinding rod 40 and the guide sleeve 60 is introduced, the grinding quality is improved, and the service lives of the grinding rod 40 and the guide sleeve 60 are prolonged.
In some embodiments, to improve the stability of the grinding rod 40 and the wind lever 50, a structure as shown in fig. 1 to 2 and 4 may be employed. Referring to fig. 1 to 2 and 4, the multifunctional pipe inner wall processing apparatus further includes a supporting device 70, and a supporting roller 71 is provided on a top of the supporting device 70, and the supporting roller 71 is used to support the grinding rod 40 or the air bar 50 between the running rail 10 and the ductile iron pipe. The supporting device 70 is similar to the guiding sleeve 60 in function, and is used for stabilizing and supporting the grinding rod 40 and the wind rod 50, so that the lengths of the grinding rod 40 and the wind rod 50 are required to meet the length of the nodular cast iron pipe, and the supporting device 70 and the guiding sleeve 60 are arranged at two ends of the grinding rod 40 or the wind rod 50 in an approximate mode, so that the grinding rod 40 and the wind rod 50 are prevented from sagging due to the length process, the working states of the grinding rod 40 and the wind rod 50 can be stabilized, and the processing quality is improved; the grinding rod 40 and the air bar 50 need to move when working, so the supporting roller 71 can meet the running state of the grinding rod 40 and the air bar 50, prevent the grinding rod 40 and the air bar 50 from moving due to large friction, and reduce the advancing resistance.
Specifically, in the axial direction of the supporting roller 71, the outer diameter thereof gradually increases from the middle portion to both ends, so that when the grinding rod 40 or the wind rod 50 is placed on the supporting roller 71, both ends of the supporting roller 71 in the axial direction play a role in limiting, the grinding rod 40 or the wind rod 50 is prevented from moving in the axial direction of the supporting roller 71, and a stable working state of the grinding rod 40 and the wind rod 50 is ensured.
