In one aspect of the embodiments of the present application, a concrete pump pipe is provided, as shown in fig. 1 and 2, and includes a conveying pipe 3 and a composite detection layer 2. The delivery pipe 3 is configured to deliver concrete; the composite detection layer 2 comprises a detection sensing layer 21 coated outside the conveying pipe 3 and a protection layer 22 coated outside the detection sensing layer 21, and the detection sensing layer 21 is a conductive layer to detect the abrasion of the conveying pipe 3. Because the conveying pipe 3 is externally coated with the detection sensing layer 21, the composite detection layer 2 is used for detecting the electrical characteristic change of the concrete pump pipe 1 so as to indicate the abrasion of the concrete pump pipe 1, and the problem of leakage caused by the damage of the concrete pump pipe 1 can be found in time. Meanwhile, the composite detection layer 2 further comprises a protection layer 22 coated outside the detection sensing layer 21, the protection layer 22 has certain strength, can bear the pressure of the concrete pump pipe in the concrete pump pipe 1 in a short time, and maintains necessary conditions required by replacing the new concrete pump pipe 1, so that the problems of slurry leakage and man-machine safety caused in the process of finishing the abrasion of the concrete pump pipe 1 are solved.
In an embodiment, duct 3 is configured such that at least the outer layer is a non-conductive layer, for example rubber in a non-conductive polymer, a polyurethane material or ABS; delivery tube 3 may also be configured such that at least the outer layer is a conductive layer, such as an elastomer or epoxy material mixed with a carbon or metal material in a conductive polymer, or a polyaniline material. Preferably, the conveying pipe 3 is configured such that at least the outer layer is made of metal, and the outer layer made of metal has sufficient strength to ensure the service life and safety performance of the concrete pump pipe 1.

When the concrete pump pipe 1 is used for conveying a conductive material, such as concrete slurry, the composite detection layer 2 of the present embodiment is used. When the concrete pump pipe 1 is not damaged, the resistance between the conveying pipe 3 and the detection sensing layer 21 is infinite because the insulating layer 23 is arranged between the two. When the concrete pump pipe 1 is worn through by the damage of concrete slurry, the concrete slurry directly contacts with the insulating layer 23 of the composite detection layer 2, and the insulating layer 23 of the composite detection layer 2 is easily damaged, so that the concrete slurry quickly wears through the insulating layer 23 and directly contacts with the detection sensing layer 21. Because the concrete slurry has high conductivity, the resistance between the conveying pipe 3 and the detection sensing layer 21 becomes small, and the damage of the concrete pump pipe 1 is timely discovered by monitoring the change of the resistance between the conveying pipe 3 and the detection sensing layer 21.

When the concrete pump pipe 1 is not damaged, the insulating layer 23 is arranged between the conveying pipe 3 and the detection sensing layer 21, and the insulating layer 23 is arranged between the detection sensing layer 21 and the protective layer 22, so that the resistance between the detection sensing layer 21 and the protective layer 22 is infinite. When the concrete pump pipe 1 is worn through by the damage of concrete slurry, the concrete slurry directly contacts with the insulating layer 23 of the composite detection layer 2, and because the insulating layer 23 of the composite detection layer 2 is easily damaged, the concrete slurry quickly wears through the insulating layer 23 to directly contact with the detection sensing layer 21, and then the wearing detection sensing layer 21 and the insulating layer 23 arranged between the detection sensing layer 21 and the protective layer 22 directly contact with the protective layer 22. Because the concrete slurry has high conductivity, the resistance between the protective layer 22 and the detection sensing layer 21 is reduced, and the damage of the concrete pump pipe 1 can be timely found by monitoring the change of the resistance between the protective layer 22 and the detection sensing layer 21.
In one embodiment, the composite detection layer 2 further comprises an insulating layer 23; the carrier pipe 3 is arranged such that at least the outer layer is a conductive layer, the protective layer 22 is a conductive layer, and an insulating layer 23 is provided between the detection sensor layer 21 and the protective layer 22. When the concrete pump pipe 1 is used for conveying a conductive material, such as concrete slurry, the composite detection layer 2 of the present embodiment is used. When the concrete pump pipe 1 is not damaged, the insulating layer 23 is arranged between the detection sensing layer 21 and the protective layer 22, so that the resistance between the conveying pipe 3 or the detection sensing layer 21 and the protective layer 22 is infinite. When the concrete pump pipe 1 is damaged by concrete slurry and worn through, the concrete slurry directly contacts with the detection sensing layer 21 of the composite detection layer 2, the concrete slurry quickly wears through the detection sensing layer 21 and the insulation layer 23, and the worn-through insulation layer 23 directly contacts with the protection layer 22 because the insulation layer 23 of the composite detection layer 2 is easily damaged. Because the concrete slurry has high conductivity, the resistance between the detection sensing layer 21 or the conveying pipe 3 and the protective layer 22 becomes small, and the damage of the concrete pump pipe 1 can be found in time by detecting the change of the resistance between the detection sensing layer 21 or the conveying pipe 3 and the protective layer 22.
In one embodiment, the composite detection layer 2 further comprises an insulating layer 23; the feed pipe 3 is configured as a non-conductive layer, the protective layer 22 is a conductive layer, and an insulating layer 23 is provided between the detection sensor layer 21 and the protective layer 22. When the concrete pump pipe 1 is used for conveying a conductive material, such as concrete slurry, the composite detection layer 2 of the present embodiment is used. When the concrete pump pipe 1 is not damaged, the insulating layer 23 is arranged between the detection sensing layer 21 and the protective layer 22, so that the resistance between the detection sensing layer 21 and the protective layer 22 is infinite. When the concrete pump pipe 1 is damaged by concrete slurry and worn through, the concrete slurry directly contacts with the detection sensing layer 21 of the composite detection layer 2, the concrete slurry quickly wears through the detection sensing layer 21 and the insulation layer 23, and the worn-through insulation layer 23 directly contacts with the protection layer 22 because the insulation layer 23 of the composite detection layer 2 is easily damaged. Because the concrete slurry has high conductivity, the resistance between the detection sensing layer 21 and the protective layer 22 becomes small, and the damage of the concrete pump pipe 1 can be found in time by detecting the change of the resistance between the detection sensing layer 21 and the protective layer 22.

When the concrete pump pipe 1 is not damaged, the insulating layer 23 is arranged between the two detection sensing layers 21, so that the resistance between the two detection sensing layers 21 is infinite. When the concrete pump pipe 1 is damaged by concrete slurry and worn through, the concrete slurry directly contacts with the detection sensing layer 21 close to the conveying pipe 3, the concrete slurry quickly wears through the detection sensing layer 21 close to the conveying pipe 3 and directly contacts with the insulating layer 23, and the detection sensing layer 21 close to the protective layer 22 directly contacts after the insulating layer 23 is worn through. Because the concrete slurry has high conductivity, the resistance between the two detection sensing layers 21 is reduced, and the damage of the concrete pump pipe 1 can be timely found by monitoring the change of the resistance between the two detection sensing layers 21.
In one embodiment, referring to FIG. 4, the composite sensing layer 2 further comprises an insulating layer 23, the delivery tube 3 is configured such that at least the outer layer is a conductive layer, and the insulating layer 23 is disposed between the delivery tube 3 and the sensing layer 21. When the protective layer 22 is a conductive layer, an insulating layer 23 is provided between the protective layer 22 and the detection sensing layer 21. When the protective layer 22 is a non-conductive layer, the insulating layer 23 may be provided between the protective layer 22 and the detection sensing layer 21, or the insulating layer 23 may not be provided. When the concrete pump pipe 1 is used for conveying non-conductive materials, the composite detection layer 2 of the embodiment is adopted. When the concrete pump pipe 1 is not damaged, the detection sensing layer 21 is a conductive layer, and the resistance at two ends of the detection sensing layer 21 is infinitesimal. When the concrete pump pipe 1 is damaged by the non-conductive material and worn through, the non-conductive material is in direct contact with the insulating layer 23 of the composite detection layer 2, and the insulating layer 23 of the composite detection layer 2 is easily damaged, so that the non-conductive material quickly wears through the insulating layer 23, the detection sensing layer 21 is disconnected, and the resistance becomes infinite. The damage of the concrete pump pipe 1 can be found in time by detecting and detecting the change of the resistance at the two ends of the sensing layer 21.
In one embodiment, referring to FIG. 4, the composite sensing layer 2 further includes an insulating layer 23, the delivery tube 3 is configured as a non-conductive layer, and the insulating layer 23 may or may not be disposed between the delivery tube 3 and the sensing layer 21. When the protective layer 22 is a conductive layer, an insulating layer 23 is provided between the protective layer 22 and the detection sensing layer 21. When the protective layer 22 is a non-conductive layer, the insulating layer 23 may be provided between the protective layer 22 and the detection sensing layer 21, or the insulating layer 23 may not be provided. When the concrete pump pipe 1 is used for conveying non-conductive materials, the composite detection layer 2 of the embodiment is adopted. When the concrete pump pipe 1 is not damaged, the detection sensing layer 21 is a conductive layer, and the resistance at two ends of the detection sensing layer 21 is infinitesimal. When the concrete pump pipe 1 is worn out by the non-conductive material, the detection sensing layer 21 is disconnected, and the resistance becomes infinite.

In one embodiment, the composite detection layer 2 is completely coated outside the conveying pipe 3 along the length direction of the conveying pipe 3. When conveyer pipe 3 outer edge conveyer pipe 3's length direction full cladding has compound detection layer 2, realizes detecting the full scope of conveyer pipe 3, can both in time discover when the damage appears in the any place of conveyer pipe 3, guarantees to put the problem of accomplishing the process and not appearing leaking thick liquid and causing man-machine safety from discovery concrete pump pipe 1 wearing and tearing everywhere.
In one embodiment, referring to fig. 1, the composite detection layer 2 is partially coated outside the delivery pipe 3 along the length direction of the delivery pipe 3, so that two ends of the delivery pipe 3 are left empty by a predetermined length to connect adjacent concrete pump pipes 1. Conveyer pipe 3 is formed with the link in the tip of reserving empty preset length, and the link of conveyer pipe 3 is convenient for pass through connecting pipe 5 with adjacent conveyer pipe 3's link and is connected fixedly, because connecting pipe 5 generally designs to be bigger than conveyer pipe 3's intensity for the position appearance conversion between adjacent arm festival, connecting pipe 5 generally designs to the return bend.

The concrete conveying pipe 3 is a main working device of the concrete pump truck 100, the conveying material is generally solid-liquid mixed concrete, the inner wall of the conveying pipe 3 is continuously abraded by the solid-liquid mixed concrete medium during pumping work, and after a certain working time, the pipe wall of the conveying pipe 3 is abraded and leaked, so that the concrete pump pipe 1 fails.
At present, whether a concrete pump pipe of a concrete pump truck fails or not is judged by visually observing whether the concrete pump pipe leaks slurry or not, once slurry leakage is found, the concrete pump truck must be stopped, replaced by a new concrete pump pipe or other emergency remedial measures, and as the concrete pump truck is a construction machine with a higher operation height, once slurry leakage is found and disposed in time, concrete slurry containing stone particles can be poured, equipment is damaged if the slurry is light, and personal safety is endangered if the slurry is heavy.
Due to the common influence of the solid-liquid mixing characteristic of the concrete, the flow field characteristic during flowing, the heat treatment difference of pipe fitting materials and other uneven factors, the concrete has uncertainty on the first worn part of the straight pipe, the difference between the worn concrete pump pipe and the unworn concrete pump pipe is large, and other concrete pump pipes possibly have long service lives after a certain part of the concrete pump pipe is worn out and loses efficacy. The concrete pump truck provided by the embodiment of the application detects the damaged conveying pipe 3 through the composite detection layer 2 and the monitoring device 6 which are designed to fully cover the concrete pump pipe 1 or fully cover the part of the concrete pump pipe 1 which is easy to damage, so that timely replacement is realized, the safe operation of pumping construction is guaranteed, and the use cost of the concrete pump pipe 1 is reduced.
In one embodiment, the monitoring device 6 is configured as at least one of a voice prompt, an audible alarm, a light alarm to indicate wear of the concrete pump pipe 1. After the monitoring device 6 detects that the electrical characteristics of the concrete pump pipe 1 change, a signal is sent to indicate the abrasion of the concrete pump pipe 1, and the secondary instrument is used for timely alarming and displaying the position of the failed concrete pump pipe 1.
In the concrete pump truck in the embodiment of the application, the monitoring device 6 is electrically connected with the concrete pump pipe 1 through a wire or wirelessly.
