[0026] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the present disclosure proposes a device for measuring the wear value of a hob 100, wherein the hob 100 includes: a blade body 101 and a blade 102 arranged in sequence along a first direction, and the measuring device includes: a measuring plate 1, a first scale 2, an indicator plate 3 and a reset assembly 4, wherein the measuring plate 1 is used to abut against the blade body 101, the first scale 2 is arranged on the measuring plate 1 along the first direction, the indicator plate 3 is slidably arranged on the measuring plate 1 along the first direction, and the indicator plate 3 is arranged close to the first scale 2, the reset assembly 4 is arranged between the indicator plate 3 and the measuring plate 1, and the reset assembly 4 is used to apply a reset force close to the blade 102 on the indicator plate 3 to make the indicator plate 3 abut against the blade 102.

[0028] It can be understood that since the indicator plate 3 is slidably arranged on the measuring plate 1 along the first direction, and the indicator plate 3 is arranged close to the first scale 2, the reset component 4 is arranged between the indicator plate 3 and the measuring plate 1, so that when the measuring plate 1 and the blade body 101 are in contact, the indicator plate 3 can be in contact with the blade 102 under the force of the reset component 4, thereby using the indicator plate 3 and the first scale 2 to indicate the size of the blade 102. Therefore, when the operator uses the measuring device to measure the blade 102, the wear value of the blade 102 can be quickly obtained based on the size of the blade 102 before wear and the size of the blade 102 after wear, thereby realizing the wear value measurement of the hob 100, meeting the needs of tool management.

[0029] Among them, the indicator plate 3 uses the reset component 4 to achieve abutment and reset with the blade 102, thereby effectively simplifying the measurement operation of the blade 102 wear value, not only improving the measurement efficiency and measurement accuracy, but also reducing safety risks in complex construction environments.

[0030] It should be noted that shield machines and other equipment require tool management when tunneling in hard rock formations. Measuring the wear value of the disc cutter is an important part of tool management and the basis for formulating cutter replacement plans for construction projects. However, due to the complex underground construction environment, operators face the following risks when measuring the wear value of the disc cutter:

[0031] The workers measure the 100-degree wear value of the cutter in the soil bin, which is a confined space operation and carries risks such as suffocation and poisoning. The common shield machine cutterhead diameter is 6 to 9 meters, and workers usually need to stand on the cutterhead to measure. The lower part of the soil bin is filled with debris, mud, and accumulated water. Once a fall accident occurs, it is very likely to cause casualties. It generally takes 30 to 60 minutes to complete the measurement of the entire disc cutter wear value. The high temperature and high dust content working environment in the soil bin can easily endanger the health of the workers and increase the probability of occupational diseases. When using traditional measuring tools to read and change the measuring objects, the workers need to use both hands to complete the measurement, which makes it difficult to achieve the "three-point contact principle" required for high-altitude operations. As a result, the workers are in a tense state due to the unstable center of gravity, resulting in low measurement efficiency and poor accuracy.

[0032] In the present embodiment, when the measuring plate 1 and the blade body 101 are in contact, the indicator plate 3 uses the reset component 4 to achieve contact and reset with the blade 102, thereby cooperating with the first scale 2 to measure the wear value of the blade 102. Due to the reset force of the reset component 4, the measuring device can achieve single-handed operation when measuring the wear value of the blade 102, thereby making the measurement operation simpler, thereby effectively improving the measurement efficiency and measurement accuracy. Moreover, with the increase in measurement efficiency and measurement accuracy, the operating time of the operator is shortened, thereby reducing the risk of the operator in a complex construction environment. At the same time, the single-handed operation allows the operator to have more energy for standing, climbing, moving, etc., which is safer.

[0033] The roller cutter 100 is used for tunneling of a shield machine. The roller cutter 100 includes: a blade body 101 and a blade 102 arranged in sequence along a first direction. The blade body 101 serves as the main structure of the roller cutter 100 and is used to support the blade 102 on the cutter disc. The blade 102 is used for cutting operations. The specific types of the blade body 101 and the blade 102 can be set according to actual needs and are not limited to this. For example, the blade body 101 and the blade 102 are respectively arranged along the first direction, and the blade body 101 and the blade 102 are connected. The width of the blade 102 decreases linearly in the direction away from the blade body 101, and the maximum width of the blade 102 is less than the minimum width of the blade body 101.

[0034] The measuring board 1 is used to carry the indicator board 3, the first scale 2, etc. The specific type of the measuring board 1 can be set according to actual needs and is not limited to this.

[0035] The first scale 2 is used to cooperate with the indicator plate 3 to identify the size of the blade 102. The specific type of the first scale 2 can be set according to actual needs and is not limited to this. For example, the first scale 2 has multiple scale lines, one long scale line and four short scale lines as a group, and the multiple groups of scale lines are arranged in sequence along the first direction. The identification value of the first scale 2 increases in the direction close to the blade 102, and the first scale 2 can be an accuracy of 1mm.

[0036] The indicator plate 3 is used to lean against the blade 102 under the force of the reset assembly 4, so as to intuitively indicate the size of the blade 102 on the first scale 2. The specific type of the indicator plate 3 can be set according to actual needs and is not limited to this. For example, the indicator plate 3 is a strip plate structure, and the indicator plate 3 is abutted against the measuring plate 1 and arranged parallel to the scale lines of the first scale 2.

[0037] The reset component 4 is used to apply a reset force on the indicator plate 3 close to the blade 102 so that the indicator plate 3 and the blade 102 abut against each other. The specific type of the reset component 4 can be set according to actual needs and is not limited to this.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the measuring plate 1 includes: a first plate 11, a second plate 12, and a third plate 13. The indicator plate 3 is slidably disposed on the first plate 11 along a first direction, and the reset assembly 4 is disposed between the indicator plate 3 and the first plate 11. The second plate 12 is disposed at one end of the first plate 11 along the first direction, and the end of the second plate 12 away from the first plate 11 is configured to abut one side of the blade 101. The third plate 13 is disposed at one end of the first plate 11 away from the second plate 12 along the first direction, and the end of the third plate 13 away from the first plate 11 is configured to abut the other side of the blade 101. A first opening 14 is formed between the first plate 11, the second plate 12, and the third plate 13, and is configured to accommodate the blade 102. The first scale 2 is disposed on the second plate 12 and / or the third plate 13 along the first direction.

[0039] It can be understood that the first plate body 11, the second plate body 12 and the third plate body 13 are connected to form a U-shaped measuring plate 1, which not only makes the measuring plate 1 have higher stability but also has a lighter weight, thereby making the measurement of the wear value of the blade 102 more convenient. In addition, the U-shaped measuring plate 1 can form a first opening 14 to accommodate the blade 102, so that when the measuring plate 1 and the blade body 101 are in contact, the blade 102 can be located in the first opening 14 and in contact with the indicator plate 3, thereby achieving the measurement of the wear value of the blade 102 while making the measuring device have a smaller volume, thereby making the use of the measuring device more convenient.

[0040] It should be noted that the first plate 11, the second plate 12 and the third plate 13 are used to form a U-shaped measuring plate 1. The specific types of the first plate 11, the second plate 12 and the third plate 13 can be set according to actual needs and are not limited to this. For example, the first plate 11, the second plate 12 and the third plate 13 are respectively long strip-shaped plate structures, and the second plate 12 and the third plate 13 are symmetrically arranged at both ends of the first plate 11, and the first scale 2 is etched on the second plate 12 and the third plate 13.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, a first notch is provided at one end of the second plate body 12 away from the first plate body 11, and a second notch is provided at one end of the third plate body 13 away from the first plate body 11. The first notch and the second notch are arranged opposite to each other and form a second opening 15, and the second opening 15 is used to clamp one end of the blade body 101 close to the blade 102.

[0042] It can be understood that since the second plate body 12 is provided with a first notch at the end away from the first plate body 11, and the third plate body 13 is provided with a second notch at the end away from the first plate body 11, the second opening 15 formed by the first notch and the second notch can be clamped on the end of the blade 101 close to the blade 102, thereby realizing the positioning of the measuring device on the hob 100, which not only ensures the stable abutment between the indicator plate 3 and the blade 102, but also ensures the consistency of multiple measurements, thereby ensuring the accurate measurement of the wear value of the hob 100 by the measuring device.

[0043] It should be noted that the first notch is used to clamp one side of the blade body 101, and the second notch is used to clamp the other side of the blade body 101. Through the arrangement of the first notch and the second notch, not only the positioning of the measuring plate 1 in the first direction of the hob 100 is achieved, but also the positioning of the measuring plate 1 in the second direction of the hob 100 is achieved, wherein the second direction is perpendicular to the first direction and is the width direction of the hob 100.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the measuring device further includes: a push rod 5 , which is slidably arranged on the measuring plate 1 along a first direction, and an indicator plate 3 is arranged at one end of the push rod 5 close to the blade 102 .

[0045] It can be understood that since the push rod 5 is set on the measuring plate 1 for sliding along the first direction, and the indicator plate 3 is set at the end of the push rod 5 close to the blade 102, the indicator plate 3 can use the push rod 5 to achieve stable sliding on the measuring plate 1, thereby ensuring that the indicator plate 3 accurately identifies the wear value of the blade 102.

[0046] It should be noted that the push rod 5 is used for the sliding setting of the measuring plate 1. The specific type of the push rod 5 can be set according to actual needs and is not limited to this. For example, the push rod 5 is a long plate structure and the push rod 5 is set along the first direction.

[0047] like Figure 1 As shown, in some embodiments, the measuring device further includes: a second scale 6, which is arranged on the push rod 5 along the first direction.

[0048] It can be understood that since the second scale 6 is arranged on the push rod 5 along the first direction, the push rod 5 can drive the second scale 6 to move relative to the measuring plate 1 when it moves with the indicator plate 3, so that the second scale 6 is used to measure the wear value of the blade 102. Moreover, through the cooperation between the second scale 6 and the first scale 2, the operator can observe the wear value of the blade 102 from multiple perspectives and multiple positions, which not only makes the use of the measuring device more convenient, but also reduces the risk of falling due to special actions during climbing.

[0049] It should be noted that the second scale 6 is used to cooperate with the indicator plate 3 to identify the size of the blade 102. The specific type of the second scale 6 can be set according to actual needs and is not limited to this. For example, the second scale 6 has multiple scale lines, one long scale line and four short scale lines as a group, and the multiple groups of scale lines are arranged in sequence along the first direction. The identification value of the second scale 6 increases in the direction close to the blade 102, and the second scale 6 can be an accuracy of 1mm.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the measuring device further includes: a cover plate 7, the cover plate 7 is arranged on the measuring plate 1, and a slide groove arranged along a first direction is formed between the cover plate 7 and the measuring plate 1, the push rod 5 slides along the first direction through the slide groove, and when the wear value of the blade 102 is zero, the cover plate 7 is flush with the zero scale line of the second scale 6.

[0051] It can be understood that since a sliding groove arranged along the first direction is formed between the cover plate 7 and the measuring plate 1, the push rod 5 slides through the sliding groove along the first direction, so that the push rod 5 can utilize the limit of the cover plate 7 to achieve a stable sliding setting on the measuring plate 1, thereby ensuring that the indicator plate 3 accurately identifies the wear value of the blade 102.

[0052] Moreover, since when the wear value of the blade 102 is zero, the cover plate 7 is flush with the zero scale line of the second scale 6, the wear value of the blade 102 can match the scale of the second scale 6, making it convenient for the operator to use the second scale 6 to accurately and quickly obtain the wear value of the blade 102, thereby improving the efficiency and accuracy of measuring the wear value of the hob 100.

[0053] It should be noted that the cover plate 7 is used to limit the push rod 5 to achieve the sliding setting of the push rod 5. The specific type of the cover plate 7 can be set according to actual needs and is not limited to this. For example, the cover plate 7 is a rectangular plate.

[0054] When the wear value of the blade 102 is zero, the cover plate 7 is flush with the zero scale line of the second scale 6, that is, the reading of the second scale 6 relative to the cover plate 7 is the wear value of the blade 102. For example, when the reading of the second scale 6 relative to the cover plate 7 is zero, it means that the wear value of the blade 102 is zero; when the reading of the second scale 6 relative to the cover plate 7 is one, it means that the wear value of the blade 102 is one.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the measuring device further includes: a plurality of bolts 8, the threaded portion of the bolts 8 passes through the cover plate 7 and the measuring plate 1 and is threadedly connected to the nut, and the plurality of bolts 8 are distributed on both sides of the slide groove.

[0056] It can be understood that since the threaded portion of the bolt 8 passes through the cover plate 7 and the measuring plate 1 and is connected to the nut thread, and multiple bolts 8 are distributed on both sides of the slide groove, the cover plate 7 is stably set on the measuring plate 1 by using multiple bolts 8 while being easy to disassemble and assemble, thereby making the use of the measuring device more convenient.

[0057] It should be noted that bolts 8 are used to detachably secure cover plate 7 to measurement plate 1. The specific type of bolts 8 can be selected based on actual needs and is not limited thereto. The number of bolts 8 can be two, three, or four, for example, four bolts 8 can be arranged in groups of two, symmetrically distributed on both sides of the chute.

[0058] like Figure 1 As shown, in some embodiments, the reset assembly 4 includes: a first elastic cord 41 and a second elastic cord 42, one end of the first elastic cord 41 is connected to the push rod 5, and the end of the first elastic cord 41 away from the push rod 5 is connected to the measuring plate 1, the first elastic cord 41 is used to apply a reset force close to the blade 102 on the push rod 5 so that the indicator plate 3 and the blade 102 abut, one end of the second elastic cord 42 is connected to the push rod 5, and the end of the second elastic cord 42 away from the push rod 5 is connected to the measuring plate 1, the second elastic cord 42 is used to apply a reset force close to the blade 102 on the push rod 5 so that the indicator plate 3 and the blade 102 abut.

[0059] It can be understood that since one end of the first elastic rope 41 is connected to the push rod 5, and the end of the first elastic rope 41 away from the push rod 5 is connected to the measuring plate 1, the push rod 5 can use the force of the first elastic rope 41 to drive the indicator plate 3 to move in the direction close to the blade 102 until the indicator plate 3 and the blade 102 are stably abutted. Therefore, the provision of the first elastic rope 41 ensures that the measuring device can efficiently and accurately measure the wear value of the roller cutter 100.

[0060] Since one end of the second elastic rope 42 is connected to the push rod 5, and the end of the second elastic rope 42 away from the push rod 5 is connected to the measuring plate 1, the push rod 5 can use the force of the second elastic rope 42 to drive the indicator plate 3 to move in the direction close to the blade 102 until the indicator plate 3 and the blade 102 are stably abutted. Therefore, the provision of the second elastic rope 42 ensures that the measuring device can efficiently and accurately measure the wear value of the roller cutter 100.

[0061] The cooperation between the first elastic rope 41 and the second elastic rope 42 makes the force applied to the push rod 5 more uniform, thereby further ensuring the stable contact between the indicator plate 3 and the blade 102 .

[0062] It should be noted that the first elastic cord 41 is used to apply a reset force on the push rod 5 close to the blade 102. The specific type of the first elastic cord 41 can be set according to actual needs and is not limited to this. For example, the first elastic cord 41 can be a rubber cord, one end of the first elastic cord 41 is connected to the through hole at the end of the push rod 5 away from the indicator plate 3, and the other end of the first elastic cord 41 is connected to the through hole at the end of the first plate body 11 close to the second plate body 12.

[0063] The second elastic cord 42 is used to apply a reset force on the push rod 5 close to the blade 102. The specific type of the second elastic cord 42 can be set according to actual needs and is not limited to this. For example, the second elastic cord 42 can be a rubber cord, one end of the second elastic cord 42 is connected to the through hole at the end of the push rod 5 away from the indicator plate 3, and the other end of the second elastic cord 42 is connected to the through hole at the end of the first plate body 11 close to the third plate body 13.

[0064] The push rod 5 and the indicator plate 3 form a plate structure that is close to an I-shape.

[0065] The through holes at both ends of the first plate 11 may be Φ16 mm holes, and the through hole on the push rod 5 may be Φ5 mm holes.

[0066] like Figure 1 As shown, in some embodiments, when the wear value of the blade 102 is zero, the indicator plate 3 is flush with the zero scale line of the first scale 2 .

[0067] It can be understood that when the wear value of the blade 102 is zero, the indicator plate 3 is flush with the zero scale line of the first scale 2, so that the wear value of the blade 102 can match the scale of the first scale 2, thereby facilitating the operator to use the first scale 2 to accurately and quickly obtain the wear value of the blade 102, thereby improving the efficiency and accuracy of measuring the wear value of the hob 100.

[0068] It should be noted that when the wear value of the blade 102 is zero, the cover 7 and the zero scale line of the first scale 2 are flush, that is, the reading of the first scale 2 relative to the cover 7 is the wear value of the blade 102. For example: when the reading of the first scale 2 relative to the cover 7 is zero, it means that the wear value of the blade 102 is zero; when the reading of the first scale 2 relative to the cover 7 is one, it means that the wear value of the blade 102 is one.

[0069] In some embodiments, the measuring device further comprises: an anti-fall rope, which is arranged on the measuring board 1 , and a loop is provided at one end of the anti-fall rope away from the measuring board 1 .

[0070] It can be understood that since the anti-fall rope is set on the measuring board 1, and a loop is provided at the end of the anti-fall rope away from the measuring board 1, the anti-fall rope can be set on the operator's wrist or other positions using the loop, thereby avoiding problems such as the measuring board 1 falling, and making the use of the measuring device more convenient.

[0071] It should be noted that the anti-fall rope is used to prevent the measuring plate 1 from falling. The specific type of the anti-fall rope can be set according to actual needs and is not limited to this. For example, the anti-fall rope can be a soft rope structure. One end of the anti-fall rope is tied to the through hole of the measuring plate 1, and the other end of the anti-fall rope is formed into a loop by winding, and the loop is put on the wrist of the operator.

[0072] When measuring the wear value of a hob cutter 100 using the measuring device of this embodiment, the second opening 15 of the measuring plate 1 is first positioned against the end surfaces of the blade 101 (serving as a positioning reference). Under the tension of the first and second elastic cords 41 and 42, the push rod 5 extends outward under the thrust of the blade 102. Simultaneously, the indicator plate 3 rests against the end of the blade 102 facing away from the blade 101. At this point, the operator can measure the first and second scale marks 2 and 6 while looking straight ahead. Once the measurement is complete, the push rod 5 and indicator plate 3 automatically return to their original positions under the tension of the first and second elastic cords 41 and 42, allowing the next measurement to proceed.
