Description

Technical Field

[0001] The invention belongs to the field of tunneling equipment, and in particular relates to a tunneling machine cutter head full-disc tool temperature detection system and a tunneling machine. Background Art

[0002] The cutterhead refers to the assembly of steel structures and cutters that are installed at the front end of a full-face tunnel boring machine and perform full-face excavation of the stratum through rotation or other means of movement. Cutters include roller cutters, scrapers, center cutters, tearing cutters, etc. Taking roller cutters as an example, when excavating in hard rock strata, roller cutters are the main excavation execution tools, and their rock breaking efficiency and service life are directly related to the progress and cost of the project. During the working process, the friction between the roller cutter and the rock mass generates heat, causing the roller cutter temperature to rise. Changes in temperature can reflect the wear condition, working status, and possible faults of the roller cutter. By detecting the temperature of the cutter, key properties such as wear resistance, sealing, and load-bearing capacity of the cutter can be evaluated, providing a reference for the selection, maintenance, and life prediction of the cutter.

[0003] To detect tool temperature, related technologies generally have the following two methods: One is a direct contact temperature detection system, which places the temperature sensor at the corresponding position of the cutter disc to measure the temperature of the measuring point to reflect the temperature of the cutter. However, in fact, the temperature sensor is easily damaged by the squeeze and friction of the cutter disc or slag, and its reliability is not high.

[0004] The other is a non-contact temperature detection system. For example, the utility model patent with the authorization announcement number CN221400507U of the applicant provides an adjustable camera cleaning protection device for detecting the cutter disc of a small-diameter tunnel boring machine. The device includes an adjustable protective shell, which is installed on the shield body, specifically in the center. A dual-light camera (infrared light and visible light) is arranged inside the adjustable protective shell, and the adjustable protective shell can protect the camera. The adjustable protective shell can be connected to the shield body through an angle adjustment structure, so that the dual-light camera can also follow the pitch swing, increase the visual range of the dual-light camera, and complete the temperature detection of the entire cutter disc during the rotation of the cutter disc. The dual-light camera can obtain the temperature of the cutter within its visual range.

[0005] It is not difficult to understand that the camera in the non-contact temperature detection system is not affected by the squeezing and friction of the cutter disc or the slag, and has higher reliability. However, in actual application, the applicant found that in the above scheme, the dual-light camera is installed at the center of the shield body, and its visible area is basically facing the cutter at the center, that is, the low-position cutter, which can ensure that the cutter can be photographed through the hole on the back of the cutter box (the channel for installing and removing the cutter, extending in the front-to-back direction) to obtain the temperature of the cutter. For the cutter at the edge, that is, the high-position cutter, it is basically the edgemost position of the dual-light camera's visible area, and it is difficult for the camera to capture the image of the cutter, forming a blind spot. Especially for cutter discs with larger diameters, there is a greater blind spot. Summary of the invention

[0006] The purpose of the present invention is to provide a system for detecting the temperature of the entire cutter disc of a roadheader cutter, so as to solve the technical problem that the non-contact temperature detection system in the prior art has a detection blind spot. The purpose of the present invention is also to provide a roadheader, so as to solve the same technical problem.

[0024] In order to achieve blind spot detection of all cutters on the cutter head of the tunnel boring machine, the basic concept of the present invention is to use different cameras to perform zone detection on the cutters at the high and low positions of the cutter head, and then combine them to obtain the cutter temperature at all positions on the whole cutter head. Compared with the solution of using one camera to detect all cutters on the cutter head, the camera in the present invention only needs to meet the temperature measurement of the cutters in the corresponding area. In fact, the camera can be arranged to basically face the cutters in the corresponding area, thereby solving the problem of blind spot detection.

[0025] Based on the above concept, the following embodiments are provided to further describe the present invention in detail.

[0026] The specific embodiment of the tunnel boring machine provided by the present invention is as follows: The tunnel boring machine provided in this embodiment includes a main machine and a supporting system, wherein the main machine is located as follows Figure 1 As shown, according to the provisions of the recommended national standard "Terms and Commercial Specifications for Full-face Tunnel Boring Machines" (GB / T34354-2017), the main machine refers to the general term for the excavation, propulsion and support devices of the tunnel boring machine, which generally includes a shield body 4, a cutter head 1, a main drive (not shown in the figure), etc. The main drive is installed on the shield body 4, and the cutter head 1 is installed on the rotatable part of the main drive, and rotates to break rocks under the action of the main drive. The cutter head 1 is installed with a cutter, which can be a hob, a scraper, etc.

[0027] In order to detect the temperature of the entire cutter, in this embodiment, the tunneling machine includes a temperature detection system for the entire cutter, such as Figure 1-Figure 4 As shown, the full-disc tool temperature detection system includes a high-tool-position temperature measuring device 3 and a low-tool-position temperature measuring device 2 installed on the main machine. The high-tool-position temperature measuring device 3 and the low-tool-position temperature measuring device 2 both include temperature measuring cameras, which can be defined as a high-tool-position temperature measuring camera 301 and a low-tool-position temperature measuring camera 201, respectively. The temperature measuring cameras themselves are prior art. The high-tool-position temperature measuring camera 301 and the low-tool-position temperature measuring camera 201 both have a certain temperature measurement range (which can be understood as a visible temperature measurement angle), which respectively corresponds to a high-tool-position camera temperature measurement range of 200 and a low-tool-position camera temperature measurement range of 100. The high-tool-position temperature measuring camera 301 and the low-tool-position temperature measuring camera 201 do not rotate with the tool disc 1. Accordingly, as the tool disc 1 rotates, the temperature measurement ranges of the high-tool-position temperature measuring camera 301 and the low-tool-position temperature measuring camera 201 can correspond to Figure 2 The high-knife-position camera temperature measurement area 400 and the low-knife-position camera temperature measurement area 300 shown in the figure both have set sizes, and the combination of the two can cover the entire plate of knives.

[0028] Correspondingly, the full-disc tool temperature detection system also includes a host computer unit. Specifically, the high-tool temperature measuring device 3 and the low-tool temperature measuring device 2 should be connected to the host computer unit for communication, and a wired connection can be used. Each wire harness can be connected to the host computer unit for communication through a signal adapter box 5. The host computer unit includes a computer 7 and an early warning display 6, which can be arranged in the man cabin of the tunnel boring machine.

[0029] Compared with the prior art, the high tool position temperature measurement camera 301 and the low tool position temperature measurement camera 201 in this embodiment only need to meet the tool temperature measurement requirements in their corresponding areas. In fact, the cameras can be arranged to basically face the tools in the corresponding areas, thereby solving the problem of blind spot detection.

[0030] In a preferred embodiment, Figure 1 As shown, the distance between the high-knife-position temperature measuring camera 301 and the axis of the cutter disc 1 is greater than the distance between the low-knife-position temperature measuring camera 201 and the axis of the cutter disc 1. At this time, the low-knife-position temperature measuring camera 201 is actually located closer to the center of the cutter disc 1, that is, closer to the low-knife-position cutter, and the high-knife-position temperature measuring camera 301 is located closer to the edge of the cutter disc 1, that is, closer to the high-knife-position cutter, so that both the high-knife-position temperature measuring camera 301 and the low-knife-position temperature measuring camera 201 can measure temperature at the best position, and the temperature measurement can be completed without using an ultra-wide-angle temperature measuring camera.

[0031] As a specific implementation method of installing a high-knife-position temperature measuring camera 301 and a low-knife-position temperature measuring camera 201, as Figure 1 As shown, the high-knife-position temperature measuring device 3 (camera) is installed on the shield body 4, and a mounting hole can be provided on the shield body 4. In order to be able to install the high-knife-position temperature measuring device 3 at a position closer to the edge of the cutter disc 1, a mounting hole extending obliquely downward can be provided on the shield body 4. The low-knife-position temperature measuring device 2 (camera) is installed on the fixed part of the main drive, which ensures that the low-knife-position temperature measuring device 2 (camera) can be installed at a position closer to the center of the cutter disc 1.

[0032] It should be noted here that in other embodiments, the low-knife-position temperature measuring device 2 can also be installed on the main machine belt conveyor or on the slag chute, and of course can also be installed on the shield body 4. Similarly, the high-knife-position temperature measuring device 3 can also be installed on the fixed part of the main drive.

[0033] For a hard rock tunnel boring machine (TBM), in order to ensure the strength of the cutterhead 1, the cutterhead 1 may use a box-type panel structure in the prior art. The cutterhead 1 specifically includes a panel 101, a cone plate 102, and a back plate 103. Since the high-tool position temperature measuring camera 301 detects the cutter at the edge, the back plate 103 may actually block the high-tool position temperature measuring camera 301. For this reason, for a tunnel boring machine using a box-type panel cutterhead 1, a plurality of through holes arranged at intervals in the circumferential direction may be opened at the edge of the back plate 103. The shape and specific number of the through holes are not limited, as long as the high-tool position temperature measuring camera 301 can pass through and detect the temperature of the high-tool position cutter.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, both the high-knife-position temperature measuring device 3 and the low-knife-position temperature measuring device 2 include a mounting seat, that is, a high-knife-position mounting seat and a low-knife-position mounting seat are respectively configured corresponding to the high-knife-position temperature measuring camera 301 and the low-knife-position temperature measuring camera 201, and are respectively installed on the host through the high-knife-position mounting seat and the low-knife-position mounting seat. Compared with the solution of directly opening holes at corresponding positions on the host to install the high-knife-position temperature measuring camera 301 and the low-knife-position temperature measuring camera 201, this method can more efficiently assemble the various parts of the structure into a module first and then install the entire structure at the corresponding position of the host.

[0035] In order to protect the high knife position temperature measuring camera 301 and the low knife position temperature measuring camera 201, a protective structure is also provided on the high knife position mounting seat and the low knife position mounting seat. Figure 3 As shown, the protective structure on the low-knife temperature measuring device 2 includes a protective shell and a protective net installed at the front end of the protection. For ease of description, the protective shell here can be defined as a first protective shell 206, and the protective net can be defined as a first protective net 205. Similarly, as Figure 4 As shown, the protective structure on the high-knife position temperature measuring device 3 also includes a protective shell and a protective net installed at the front end of the protective shell. The protective shell here can be defined as a second protective shell, and the protective net can be defined as a second protective net 303. The protective net is provided to prevent the protective structure from blocking the camera. However, in other embodiments, the protective structure can also be made of a transparent material with higher strength, and in this case, it is not necessary to provide a separate protective net.

[0036] In order to prevent dust and impurities from adhering to the lenses of the high-knife-position temperature measurement camera 301 and the low-knife-position temperature measurement camera 201 and affecting the temperature measurement results, in a preferred embodiment, a cleaning water nozzle and an air-drying nozzle are provided on the high-knife-position mounting seat and the low-knife-position mounting seat, and the cleaning water nozzle and the air-drying nozzle are both facing the corresponding temperature measurement camera. Figure 3 As shown, taking the low-position tool mounting seat as an example, the low-position tool mounting seat is provided with three cleaning water nozzles and three air-drying nozzles. The cleaning water nozzles are connected to the water supply pipeline to spray cleaning water to flush the camera lens, and the air-drying nozzles are connected to the air supply pipeline to spray air with a certain pressure to air-dry the camera lens. The cleaning water nozzles here can be defined as the first cleaning water nozzle 203, and the air-drying nozzles can be defined as the first air-drying nozzles 204. Similarly, Figure 4 As shown, the high knife position mounting seat is also equipped with a cleaning water nozzle and an air drying nozzle, and accordingly, the cleaning water nozzle and the air drying nozzle can also be connected to the corresponding water and air flushing pipeline 304. It should be noted that the specific number of the cleaning water nozzle and the air drying nozzle is not limited here, and it can meet the flushing of the corresponding camera.

[0037] In order to facilitate the independent control of the water spraying / jetting of the cleaning water nozzle and the air drying nozzle, preferably, for the full-disc tool temperature detection system, such as Figure 1As shown, it is equipped with independent water supply pipelines connected to each cleaning water nozzle and air supply pipelines connected to each air drying nozzle, a water pump 8 is arranged on the water supply pipeline, and an air compressor 9 is arranged on the air supply pipeline. At this time, there is no need to connect the corresponding water and air pipelines of the main engine of the tunnel boring machine itself, which is convenient for independent control.

[0038] Furthermore, if Figure 1 As shown, the gas supply pipeline and the water supply pipeline are both provided with a manual stop valve 10 and an electromagnetic stop valve 11 in series. The manual stop valve 10 can be kept in a normally open state under normal conditions, and the on and off of the water or gas circuit can be controlled by an electrically controlled electromagnetic valve. However, considering that the internal environment of the tunnel is relatively harsh, if the electromagnetic stop valve 11 fails or is damaged, it can be switched to manual stop valve 10 for manual control. This is convenient for control and can ensure reliability.

[0039] In order to accurately measure the temperature of the tool and avoid excessive dust concentration affecting the measurement results, in a preferred embodiment, Figure 3 and Figure 4 As shown, dust concentration detection sensors are provided on both the high tool position mounting seat and the low tool position mounting seat, wherein the dust concentration sensor on the low tool position mounting seat can be defined as a first dust concentration detection sensor 202, and the dust concentration sensor on the high tool position mounting seat can be defined as a second dust concentration detection sensor 302. The dust concentration can be collected in real time by the dust concentration detection sensor, and the influence of dust transmittance can be corrected according to the influence law of dust projection rate and infrared temperature measurement, so as to obtain the infrared temperature measurement result under dust projection. The specific algorithm can adopt the existing technology, such as the infrared temperature measurement method disclosed in the invention patent application with application publication number CN108593115A.

[0040] According to the temperature of the whole cutter plate measured by the whole cutter plate temperature detection system, this embodiment can realize the identification of abnormal cutters. Figure 5 As shown, the temperatures of all rollers are first identified, and certain algorithm models and rules (such as comparison of adjacent roller temperatures and comparison with critical high temperature values ​​and low temperature values, etc.) are added to determine whether the roller is abnormal. Whether it is abnormal is determined in a single excavation mileage. If it is abnormal, it is determined whether it is abnormal after a certain excavation mileage. If it is still abnormal, the roller is an abnormal roller and is pushed to the early warning display 6 for display and early warning. The construction personnel change and check the roller according to the early warning information, and reduce the on-site roller cutter wear and tear and improve the excavation efficiency through scientific tool change.

[0041] The specific embodiment of the whole-disc tool temperature detection system for the tunnel boring machine cutter head provided by the present invention is as follows: The embodiment of the full-disc tool temperature detection system for the tunnel boring machine cutter head is the full-disc tool temperature detection system described in the above-mentioned specific embodiment of the tunnel boring machine, and will not be described in detail here.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
