Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine cutter installation technology, specifically, to a tooling for quickly detecting the installation status of cutterhead cutters. Background Technology

[0002] With the continuous development of urban underground space, trenchless construction technology has been widely applied. Among them, miniature tunnel boring machines (TBMs) are widely used in the construction of municipal pipelines, integrated utility tunnels, and cable tunnels due to their advantages such as minimal impact on surface traffic and the environment and flexible construction. The cutterhead of the TBM is its core tunneling component, on which various types of cutting tools are installed. The quality of the cutting tool installation, including the extent of tool extension, the tool deflection angle, and the overall installation posture, directly determines the rock-breaking efficiency and stability of the cutterhead, and is a key factor affecting the tunneling performance, construction safety, and even the overall lifespan of the TBM.

[0003] In micro-shield tunneling, the installation quality of the cutterhead and cutting tools is crucial. Currently, when measuring the installation status of the cutting tools, using high-end inspection equipment such as 3D laser scanners is not only costly, but also requires specialized software and trained operators. On the other hand, using traditional measuring tools (such as rulers and angle gauges) generally suffers from problems such as cumbersome operation, low measurement efficiency, poor repeatability, and difficulty in ensuring accuracy, making it difficult to meet the stringent requirements of high-precision tunneling projects for the quality control of cutting tool installation. Utility Model Content

[0004] In view of the problems in related technologies, this utility model proposes a tooling for quickly detecting the installation status of the cutter head and cutting tools, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A tooling for quickly detecting the installation status of a cutter head includes a tool calibration gauge, which includes a calibration gauge shaft, a main spindle connected above the calibration gauge shaft, a sleeve connected to the outside of the main spindle via a bearing, a calibration gauge plate connected to one side of the sleeve, and a base connected below the calibration gauge shaft.

[0007] Furthermore, in order to lock the calibration gauge plate after the calibration gauge plate position is adjusted, a mounting plate is connected to the outside of the sleeve. The mounting plate has threaded holes, and a screw is threaded into the threaded holes. The base has multiple positioning holes, and the screw matches the positioning holes.

[0008] Furthermore, to facilitate the rotation of the screw, one end of the screw is connected to the rotating plate.

[0009] Furthermore, to facilitate the installation of this tool calibration gauge on the tool disc, the base is provided with mounting holes, and the base is connected to the tool disc body by bolts.

[0010] Furthermore, the bottom of the calibration gauge is equipped with scale lines.

[0011] Furthermore, a sleeve is fitted on the outer side of the calibration gauge shaft, and the sleeve is connected to the base.

[0012] Furthermore, the number of bearings is two.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting scale lines and inclined bottom edge at the bottom of the calibration gauge plate, combined with the fixed geometric relationship between it and the tool, the operator only needs to use an ordinary ruler to quickly check the three key installation parameters of the tool: extension height (vertical distance), radial position (horizontal distance) and installation tilt angle. There is no need to rely on complex instruments or professional software, which greatly improves the efficiency and operability of on-site testing. The calibration gauge shaft is supported by upper and lower bearing sleeves, which are rigidly connected to the base with the outer sleeve to form a high-rigidity, low-shaking rotation support system. This ensures that the calibration gauge plate remains stable during the rotation around the tool disc axis, effectively guaranteeing the consistency of the measurement benchmark and the repeatability of the positioning accuracy.

[0015] (2) By setting a mounting plate and a screw on one side of the sleeve, after the calibration gauge plate is rotated to the target tool position, mechanical locking can be achieved by screwing the screw on the mounting plate into the corresponding positioning hole of the base; the end of the screw is connected to a rotating plate, which facilitates quick operation by hand. This locking structure can not only prevent accidental rotation during the measurement process, but also support multi-station precise positioning, significantly improving the accuracy and safety of the inspection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a tooling for quickly detecting the installation status of the cutter head is provided.

[0026] Example 1

[0027] like Figures 1-5 As shown, the tooling for quickly detecting the tool installation status of the tool disc according to an embodiment of this utility model includes a tool calibration gauge 1. The tool calibration gauge 1 includes a calibration gauge shaft 2. A main shaft 3 is connected above the calibration gauge shaft 2. A sleeve 5 is connected to the outside of the main shaft 3 through a bearing 4. There are two bearings 4. The double bearing structure not only significantly improves the rigidity and stability of the rotation system, but also effectively reduces radial runout and shaking during operation, ensuring the reliability of the subsequent measurement benchmark. A calibration gauge plate 6 is connected to one side of the sleeve 5. A scale line 14 is provided at the bottom of the calibration gauge plate 6 for directly comparing and reading the key geometric parameters of the tool, such as height and radial position.

[0028] A base 7 is connected below the calibration gauge shaft 2. The base 7 serves as the installation foundation for the entire tooling and is responsible for docking with the cutter head body 16. A sleeve 15 is fitted on the outside of the calibration gauge shaft 2. The upper end of the sleeve 15 is transitionally fitted with the area of ​​the spindle 3, and the lower end is firmly connected to the base 7. The base 7 is provided with mounting holes 13, which can be used to quickly and reliably fix the entire calibration gauge 1 onto the cutter head body 16 with bolts, so as to achieve precise alignment between the tooling and the object being measured, which facilitates subsequent rotational inspection operations.

[0029] like Figures 1-4 As shown, a mounting plate 8 is connected to the outer side of the sleeve 5. The mounting plate 8 has a threaded hole 9, and a screw 10 is threaded into the threaded hole 9. The base 7 has multiple positioning holes 11, which are evenly distributed around the circumference or arranged according to the actual tool position, and match the end size of the screw 10. One end of the screw 10 is connected to the rotating plate 12. When the calibration gauge plate 6 is rotated to the target tool position, the operator can rotate the screw 10 to make its end engage with the corresponding positioning hole 11, thereby mechanically locking the sleeve 5 and the calibration gauge plate 6 at the required angle position, avoiding displacement or shaking during the measurement process, and improving the repeatability and accuracy of the test.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, during the preparation stage, the operator needs to connect the tool calibration gauge 1 to the cutter head body 16 through the mounting hole 13 on the base 7, and install the base 7 at the center position of the cutter head body 16, thereby providing a stable basic platform for subsequent testing. Next, the operator can manually rotate the calibration gauge plate 6, allowing it to rotate freely along the axis of the sleeve 5 until the calibration gauge plate 6 is aligned with the position of the tool to be tested. During the rotation of the calibration gauge plate 6, due to the use of a double bearing 4 structure, its operation is smooth and without shaking, and it has high repeatability. When the calibration gauge plate 6 is accurately aligned with the target tool, the operator can manually tighten the screw 10 through the rotating plate 12, so that the end of the screw 10 is embedded in the pre-set positioning hole 11 on the base 7, achieving mechanical locking of the calibration gauge plate 6. This locking mechanism effectively avoids displacement caused by accidental collisions or vibrations during the measurement process, ensuring the consistency and reliability of each measurement result.

[0032] Next, using the scale lines 14 at the bottom of the calibration gauge plate 6, the operator can directly read the key geometric parameters of the tool. The operator places a ruler vertically between the top of the tool and the bottom edge of the calibration gauge plate 6 and directly reads the gap value between them. Since the distance between the bottom edge of the calibration gauge plate 6 and the theoretical highest point is known, it is possible to quickly determine whether the current tool is higher or lower than the standard installation height, thereby assessing whether its extension meets the design requirements. Secondly, when checking the horizontal radial distance of the tool from the center of the cutter head, the operator places a ruler horizontally against the side of the tool and reads the value by referring to the radial scale lines 14 pre-marked on the panel of the calibration gauge plate 6. These scale lines 14, with the center of the cutter head as the origin, accurately mark the theoretical distance values ​​corresponding to different positions in the radial direction. By comparing the measured value with the scale indication value, it is possible to quickly determine whether there is radial offset or installation misalignment of the tool. Then, using the inclined reference edge specially machined at the bottom of the calibration gauge plate (whose angle is consistent with the standard installation tilt angle of the tool or tool box), it is compared with the actual tool cutting face or tool box mounting surface using a feeler gauge. If the two outlines fit perfectly, the tilt angle is correct; if there is a gap, the direction and degree of tilt angle deviation can be preliminarily judged, or it can be checked by the vertical and horizontal distances at the highest points.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
