Abstract
Description
Technical Field
[0001] This invention relates to the field of construction engineering technology, specifically to a mine-use full-face rapid tunneling correction mechanism applicable to multiple sizes and cross-sections. Background Technology
[0002] With the rapid development of the national economy, tunnel engineering encompasses urban underground integrated pipeline networks, railway and vehicle tunnels, and coal mine roadway excavation. An increasing number of full-face tunnel boring machines are being used in roadway excavation.
[0003] Existing coal mine roadway excavation generally uses partial face tunneling machines such as roadheaders, continuous miners, and cantilever tunneling machines. These partial face tunneling machines excavate coal roadways. Because their cutting method is open-face excavation, the direction of excavation can be determined by observing the working face during the tunneling process. Their small size also allows for timely correction of the roadway by twisting or swinging the cutting head.
[0004] In recent years, full-face tunnel boring machines (TBMs) have been adopted for cutting and tunneling. Because these TBMs cut the entire face, they occupy most of the tunnel cross-section, making it impossible to determine the direction of excavation by observing the face. Furthermore, due to the complexity of their functions, full-face TBMs generally occupy the entire tunnel space and cannot take up more space. The supporting structures of their internal cutting, propulsion, and muck removal systems, as well as their hydraulic and electrical systems, occupy a large space. The available correction components need to be arranged at the movable connection points of the equipment, and the degree of correction in a single operation determines the speed of adjustment during tunnel cutting, which is closely related to the quality of the tunnel. The degree of correction is determined by the correction structure.
[0005] The correction mechanism includes tunneling control in six directions: pitch, lateral, and roll. If the correction structure is modularized into a single unit, it needs to be positioned behind the cutting head. The greater the distance, the larger the correction angle. This approach can lead to low correction accuracy and difficulty in feedback.
[0006] Therefore, it is evident that how to achieve a high-precision correction structure within a full-face tunnel boring machine using a reasonable and optimal structure is a problem that needs to be solved in this field. Summary of the Invention

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.
[0032] To address the technical problem of low correction accuracy in existing multi-size and multi-section mining full-face rapid tunneling systems, this invention provides a correction mechanism applicable to multi-size and multi-section mining full-face rapid tunneling. This mechanism divides the correction structure in each of the left-right, pitch, and roll directions into three parts, controlling left-right correction, pitch correction, and roll correction respectively, thereby improving the reliability and accuracy of the correction performance.
[0033] See Figures 1-2 The solution provides a mine-use full-section rapid tunneling correction mechanism applicable to multiple sizes and cross sections, including a first housing 1, a second housing 2, a third housing 3, a fourth housing 4, an upper and lower correction device, a left and right correction device, a main thrust cylinder, and a support shoe.
[0034] The first housing 1 is equipped with a cutter head structure for cutting the tunnel. The cutter head structure includes two small cutter head structures 11, a middle cutter head structure, and an upper cutter head structure, and is fixed inside the first housing 1 by a locking device.
[0035] Two small cutter head structures 11 are respectively disposed on both sides of the first housing 1, and the two small cutter head structures 11 have a bottom-lying function. When one of the small cutter head structures is bottom-lying, the first housing 1 can rotate in a first position due to the resistance between the bottom-lying small cutter head and the cutting channel when it moves forward; conversely, when the other small cutter head structure is bottom-lying, the first housing 1 can rotate in the opposite position; thus, the rolling correction of the first housing 1 can be realized.
[0036] The upper and lower correction device includes an upper and lower correction cylinder assembly 5, an upper and lower correction fulcrum rotation structure 6, and an upper and lower correction torsional force cancellation structure 7.
[0037] The upper and lower correction pivot rotation structure 6 is located in the middle part between the first housing 1 and the second housing 2 and is connected to the first housing 1 and the second housing 2 respectively. See [reference needed]. Figure 3 The upper and lower correction pivot rotation structure 6 includes a first hinge seat 61 and a second hinge seat 62.
[0038] The first hinge seat 61 is fixed on the first housing 1, and the second hinge seat 62 is fixed on the second housing 2. A connecting pin 63 is provided between the first hinge seat 61 and the second hinge seat 62 to form a hinge between the first housing 1 and the second housing 2, which can form a fulcrum for the up and down movement of the first housing 1.
[0039] Secondly, an oil hole 65 is provided on the pin 63, through which lubricating oil can be injected to lubricate the pin 63.
[0040] In addition, in order to ensure the stability of the first housing 1 rotating around the upper and lower correction pivot rotation structure 6, a first stop plate 64 is provided on the pin 63 to restrict the pin 63 and prevent the pin 63 from loosening.
[0041] The upper and lower alignment cylinder assembly 5 is located above the first housing 1 and the second housing 2 and is connected to the first housing 1 and the second housing 2 respectively. See Figure 4 The upper and lower correction cylinder assembly 5 includes a first cylinder seat 51, a second cylinder seat 52, an upper and lower correction cylinder 53, and a pin 54.
[0042] The first cylinder seat 51 is welded to the first housing 1, the second cylinder seat 52 is welded to the second housing 2, the driving end of the upper and lower correction cylinder 53 is hinged to the first cylinder seat 51 through the connecting pin 54, and the connecting end of the upper and lower correction cylinder 53 is hinged to the second cylinder seat 52 through the connecting pin 54.
[0043] During operation, when the shaft end of the upper and lower correction cylinder 53 is in the extended state, the first housing 1, which is hinged to it, can rotate in the first direction around the upper and lower correction fulcrum rotation structure 6; conversely, when the shaft end of the upper and lower correction cylinder 53 is in the retracted state, the first housing 1, which is hinged to it, can rotate in the opposite direction around the upper and lower correction fulcrum rotation structure 6. Thus, the upper and lower correction of the first housing 1 and the cutter head structure on the first housing 1 can be realized.
[0044] The upper and lower correction torsional force cancellation structure 7 is disposed between the upper and lower correction cylinder assembly 5 and the upper and lower correction fulcrum rotation structure 6, and is connected to the first housing 1 and the second housing 2 respectively. See Figures 5-6 The upper and lower correction torsional force cancellation structure 7 includes a first moving block 71, a first limiting groove block 72 and a first oil cap 73.
[0045] The first moving block 71 is fixed on the first housing 1, and the first limiting groove block 72 is fixed on the second housing 2. The first moving block 71 is embedded in the first limiting groove block 72. The first moving block 71 moves within the first limiting groove block 72. The first limiting groove block 72 can limit the left and right movement of the first moving block 71 to counteract the torsional force generated by the first housing 1 during cutting, and ensure the reliability of the first housing 1 when adjusting its vertical deviation later.
[0046] In addition, to ensure a stable connection between the first moving block 71 and the first limiting groove block 72 and the first housing 1 and the second housing 2, a reinforcing plate 74 can be provided around the first moving block 71 and the first limiting groove block 72 to strengthen the connection between the first moving block 71 and the first limiting groove block 72 and the first housing 1 and the second housing 2.
[0047] The first oil cap 73 is located at the upper and lower ends of the first limiting groove 72. The first oil cap 73 is provided with an oil injection hole 75 and communicates with the first limiting groove 72. Grease can be added into the first limiting groove 72 through the oil injection hole 75 for lubrication of the first moving block 71 during movement.
[0048] The upper and lower correction cylinder assembly 5, the upper and lower correction fulcrum rotation structure 6, and the upper and lower correction torsional force cancellation structure 7 work together to achieve the upper and lower correction function of the first housing 1.
[0049] The left and right correction device includes a left and right correction cylinder assembly 8, a left and right correction fulcrum rotation structure 9, and a torsional force cancellation structure 10.
[0050] The left and right correction pivot rotation structure 9 is located in the middle part between the second housing 2 and the third housing 3 and is connected to both the second housing 2 and the third housing 3 respectively. See [reference needed]. Figure 7 The left and right correction pivot rotation structure includes a third hinge seat 91 and a fourth hinge seat 92.
[0051] The third hinge seat 91 is fixed on the second housing 2, and the fourth hinge seat 92 is fixed on the third housing 3. A connecting pin 93 is provided between the third hinge seat 91 and the fourth hinge seat 92 to form a hinge between the second housing 2 and the third housing 3, which can form a fulcrum for the up and down movement of the second housing 2.
[0052] Secondly, the pin 93 is equipped with an oil hole 95, through which lubricating oil can be injected to lubricate the pin 93.
[0053] In addition, in order to ensure the stability of the second housing 2 when rotating around the left and right correction pivot 9, a second stop plate 94 is provided on the pin 93 to restrict the pin 93 and prevent the pin 93 from loosening.
[0054] The left and right correction cylinder assembly 8 includes a first left and right correction cylinder assembly, a second left and right correction cylinder assembly, a third left and right correction cylinder assembly, and a fourth left and right correction cylinder assembly; wherein, the first left and right correction cylinder assembly, the second left and right correction cylinder assembly, the third left and right correction cylinder assembly, and the fourth left and right correction cylinder assembly are symmetrically arranged at the upper and lower ends between the second housing 2 and the third housing 3 and are respectively connected to the second housing 2 and the third housing 3.
[0055] The first and second left and right correction cylinder assemblies move synchronously, as do the third and fourth left and right correction cylinder assemblies.
[0056] The four sets of left and right correction cylinder assemblies have the same structure, see [link / reference]. Figure 3It includes a third cylinder seat 81, a fourth cylinder seat 82, an upper and lower correction cylinder 83, and a connecting pin 84.
[0057] The third cylinder 81 is fixed on the second housing 2, the fourth cylinder 82 is fixed on the third housing 3, the driving end of the left and right correction cylinders 83 is hinged to the third cylinder 81 via a connecting pin 84, and the connecting end of the left and right correction cylinders 83 is hinged to the fourth cylinder 82 via a connecting pin 84.
[0058] During operation, when the first and second left and right correction cylinder assemblies are extended, and the third and fourth left and right correction cylinder assemblies are retracted, the second housing 2, which is hinged to them, can swing in the first direction around the left and right correction fulcrum rotation structure 9. Conversely, when the first and second left and right correction cylinder assemblies are retracted, and the third and fourth left and right correction cylinder assemblies are extended, the second housing 2, which is hinged to them, can swing in the opposite direction around the left and right correction fulcrum rotation structure 9. Thus, the left and right adjustment function of the second housing 2 can be realized. Since the second housing 2 is hinged to the first housing 1, the left and right adjustment function of the first housing 1 can also be realized.
[0059] The left and right correction torsional force cancellation structure 10 is disposed between the left and right correction cylinder assembly 8 and the left and right correction fulcrum rotation structure 9, and is connected to the second housing 2 and the third housing 3 respectively. See Figure 8 The left and right correction torsional force cancellation structure 10 includes a second moving block 101, a second limiting groove block 102, and a second oil cap 103.
[0060] The second moving block 102 is fixed on the second housing 2, the second limiting groove 102 is fixed on the third housing 3, and the second moving block 101 is embedded in the second limiting groove 102. The second moving block 101 moves within the second limiting groove 102. The second limiting groove 102 can limit the up and down movement of the second moving block 101 to counteract the torsional force generated by the first housing 1 during cutting, and ensure the reliability of the left and right adjustment of the first housing 1 in the later stage.
[0061] In addition, to ensure a stable connection between the second moving block 101 and the second limiting groove block 102 and the second housing 2 and the third housing 3, a reinforcing plate 104 can be provided around the second moving block 102 and the second limiting groove 102 to strengthen the connection between the second moving block 101 and the second limiting groove block 102 and the second housing 2 and the third housing.
[0062] The second oil cap 103 is located at the upper and lower ends of the second limiting groove block 102, see [reference]. Figure 9The second oil cap 103 is provided with an oil injection hole 105 and is connected to the second limiting groove 102 block. Grease can be added into the second limiting groove 102 block through the oil injection hole 105 for lubrication of the second moving block 101 during movement.
[0063] The left and right correction cylinder assembly 8, the left and right correction fulcrum rotation structure 9, and the left and right correction torsional force cancellation structure 10 work together to achieve the left and right correction function of the first housing 1.
[0064] The main thrust cylinder 13 and the support shoe 12 are installed inside the first housing 1. The main thrust cylinder 13 is equipped with a fifth cylinder seat and a sixth cylinder seat.
[0065] The fifth cylinder seat is fixed on the third housing 3, and the sixth cylinder seat is fixed on the fourth housing 4. The shaft end and connecting end of the main push cylinder 13 are respectively connected to the fifth cylinder seat and the sixth cylinder seat.
[0066] The axial movement of the first three housings can be achieved by extending and retracting the main thrust cylinder 13.
[0067] Because the three correction structures are independently controlled, this solution can achieve simultaneous correction actions in three directions, enabling multi-directional simultaneous correction. The following example illustrates the working process of this solution in a specific application. It should be noted that the following content is only a specific application example of this solution and does not constitute a limitation on this solution.
[0068] This correction structure, applicable to multi-size and multi-section shape mining full-face high-speed tunneling machines, involves a three-directional correction process: vertical correction, horizontal correction, and rolling correction. These directional corrections can be coupled, and the operation steps for each direction are as follows:
[0069] In the initial state:
[0070] The small cutter head structure 11 is in its initial position, the upper and lower correction cylinders 53 and the left and right correction cylinders 83 are also in their initial positions, the support shoe 12 extends and presses against the coal wall to provide friction, and each cutter head rotates to cut.
[0071] Up and down correction operation process:
[0072] The upper and lower correction cylinders 53 extend, while the other cylinders remain stationary. The first housing 1 rotates around the center of the upper and lower correction pivot structure 6, and the upper and lower correction torsional force cancellation structure 6 moves simultaneously. The cutterheads inside the first housing 1 cut downwards. The main push cylinder 13 extends, and the machine moves forward, thereby realizing the downward correction of the tunneling machine. The upper and lower correction cylinders 53 retract to realize the upward correction.
[0073] Left and right correction operation process:
[0074] Two right-side correction cylinders 83 extend, and two left-side cylinders retract, while the remaining cylinders remain stationary. The second housing 2 rotates around the center of the left-right correction pivot structure 9, while the first housing 1 and the second housing 2 remain aligned. Inside the first housing 1, each cutterhead cuts to the left. The main thrust cylinder 13 extends, and the machine moves forward, thus achieving leftward correction of the tunneling machine. The left-right correction torsional force cancellation structure 10 moves simultaneously. When the two right-side correction cylinders 83 retract and the two left-side cylinders extend, rightward correction can be achieved.
[0075] Rolling correction process:
[0076] The left small cutter head structure 11 lies at the bottom, the main push cylinder 13 extends, the machine moves forward, and the new cutting roadway rotates counterclockwise to achieve rolling correction. The same applies in the opposite direction. The right small cutter head structure 11 lies at the bottom and rotates clockwise to achieve rolling correction.
[0077] The above-described scheme constitutes a mine-use full-face rapid tunneling correction mechanism applicable to multiple sizes and cross sections. It divides the correction structure in six directions (left, right, pitch, and roll) into three parts, which control left and right correction, pitch correction, and roll correction respectively. This can improve the correction range of the full-face tunneling machine, improve the correction feedback accuracy of the tunneling machine, and improve the overall tunneling quality of the tunneling machine.
[0078] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
