Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0025] It should be noted that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the purpose of simplifying the description of this application, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application. Specifically, in this application, the direction towards the ground is defined as "lower," the direction away from the ground is defined as "upper," the drilling direction of the open-face tunnel boring machine is the depth direction of the tunnel, that is, the axial direction of the open-face tunnel boring machine, and the transverse direction is the horizontal direction of the tunnel cross-section.

[0026] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts are exaggerated relative to other structural parts, and are therefore only used to illustrate the basic structure of the subject matter of this application.

[0027] This application provides a rotary working platform 1 for an open-type tunneling machine, such as... Figure 1 since Figure 7 As shown, the rotary working platform 1 is used to movably mount the working equipment on the open-face tunneling machine. The working equipment includes, but is not limited to, anchor drilling rigs and advanced directional drilling rigs. The open-face tunneling machine includes a main frame 2. The rotary working platform 1 is movably mounted on the main frame 2 and moves along the axial direction of the main frame 1 to facilitate the adjustment of the position of the working equipment relative to the main frame 2, so as to facilitate the implementation of operations as needed and provide flexible working space for the working equipment.

[0028] The rotary working platform 1 includes a gear ring assembly 10, a translation mechanism 20 for mounting the gear ring assembly 10 on the main frame 2, and a gear rotation mechanism 30 for carrying the working equipment and driving the working equipment to rotate axially around the gear ring assembly 10. The cooperation between the gear ring assembly 10, the translation mechanism 20 and the gear rotation mechanism 30 allows the working equipment to not only rotate circumferentially around the open-face tunneling machine, but also to translate back and forth relative to the open-face tunneling machine, providing a flexible working space for the working equipment and meeting the diverse operating needs of the working equipment.

[0029] The gear ring assembly 10 is generally in the form of a ring plate structure and is sleeved on the main frame 2. The gear ring assembly 10 includes a gear ring structure 11 and a fixing structure 12 symmetrically arranged on both sides of the gear ring structure 11. The fixing structure 12 is used to fix the gear ring structure 11 and strengthen the structural strength of the gear ring structure 11.

[0030] like Figure 1 and Figure 2 As shown, the gear ring structure 11 includes a body 111 and a gear ring 112 fixed to the radial end of the body 111. The body 111 is ring-shaped, and the gear ring 112 is distributed around the body 111 in the radial direction.

[0031] like Figure 2 As shown, the fixing structure 12 is fixed to the body 111. Specifically, the fixing structure 12 includes an L-shaped fixing ring plate 121 and a reinforcing ring plate 122. The fixing ring plate 121 extends in the same direction as the gear ring structure 11 and is fixed to the gear ring structure 11. The fixing ring plate 121 is fixed to the body 111 by bolts. The reinforcing ring plate 122 extends to the side of the body 111 near the end of the fixing ring plate 121. Generally, the fixing ring plate 121 and the reinforcing ring plate 122 are fixed together and then fixed to the body 111.

[0032] It is understood that the fixed ring plate 121 and the reinforcing ring plate 122 may also be integrally formed structures, which are also within the protection scope of this application.

[0033] like Figure 1 As shown, the gear ring assembly 10 is designed in sections to facilitate hoisting and installation. Specifically, the gear ring assembly 10 includes an upper gear ring section 13, a lower gear ring section 14, and a side gear ring section 15 located between the upper gear ring section 13 and the lower gear ring section 14, with each part connected by a flange.

[0034] The curvature of the upper gear segment 13 is the same as that of the lower gear segment 14, and the curvature of the side gear segment 15 is greater than that of the upper gear segment 13 and the lower gear segment 14. Preferably, the curvature of the upper gear segment 13 and the lower gear segment 14 is 36°, and the curvature of the side gear segment 15 is 144°.

[0035] It is understood that the upper gear segment 13, the side gear segment 15 and the lower gear segment 14 are all composed of a gear structure 11 and a fixing structure 12. First, the fixing structure 12 of each segment is installed on the body 111 of the gear structure 11, and then the upper gear segment 13, the side gear segment 15 and the lower gear segment 14 are assembled together, and the pitch at the splice is kept consistent with the standard pitch.

[0036] The translation mechanism 20 is used to connect the main frame 2 and the gear ring assembly 10, so that the gear ring assembly 10 can be translated axially relative to the main frame.

[0037] The translation mechanism 20 includes a wheel 21 fixed to the fixed structure 12 and a guide structure 22 for fixing to the main frame 2 and slidingly engaging with the wheel 21. In this application, the guide structure 22 is fixed to the main frame 2 by a steel plate. The guide structure 22 guides the translation of the wheel 21, allowing the wheel 21 to move smoothly along the main frame 2.

[0038] In this application, such as Figure 3 As shown, in order for the gear ring assembly 10 to translate smoothly, the translation mechanism 20 includes four pairs of wheels 21 and four corresponding pairs of guide structures 22, which are evenly and symmetrically distributed on the main frame 2 with the axis of the main frame 2 as the center, increasing the number of mating points between the gear ring assembly 10 and the main frame 2 and improving the bonding strength between the gear ring assembly 10 and the main frame 2.

[0039] The guide structure 22 has at least one inclined bearing surface 221, and the wheel 21 is provided with a groove 211 that cooperates with the bearing surface 221. The inclined surface of the groove 211 is in contact with the bearing surface 221. The groove 211 can limit the wheel 21 in the vertical translation direction and prevent the wheel 21 from deviating from the translation direction.

[0040] The cross-section of the guide structure 22 is rhomboid, and the bearing surface 221 corresponds to one side of the rhombus. The angle between the bearing surface 221 and the horizontal plane is 30°-60°. Preferably, the angle between the bearing surface 221 and the horizontal plane is 45°. Correspondingly, the inclined surface of the groove 211 is also at 45° to the horizontal plane. The bearing surface 221 located below can also support the wheel 21. Similarly, the inclined surface of the groove 211 located below also supports the guide structure 22.

[0041] like Figure 3 As shown in this application, there are two bearing surfaces 221, which respectively contact the two inclined surfaces of the groove 211. The two bearing surfaces 221 form a rhomboid corner position, which further increases the bonding strength between the wheel 21 and the guide structure 22.

[0042] The rotary work platform 1 also includes a translation cylinder 40 for driving the gear ring assembly 10 or the drive wheel 21 to move the gear ring assembly 10 relative to the main frame 2. The translation cylinder 40 in this application is used to drive the gear ring assembly 10 to translate. The mounting base of the translation cylinder 40 is fixedly installed on the main frame 2, and the end of the telescopic arm is installed on the fixed ring plate 121. Through the extension and retraction of the translation cylinder 40, the gear ring assembly 10 is driven to translate relative to the main frame 2 along the field with the assistance of the translation mechanism 20.

[0043] The gear rotation mechanism 30 is used to rotatably connect the working equipment and the gear ring assembly 10, so that the working equipment installed on the gear rotation mechanism 30 can rotate around the circumference of the gear ring structure 11, that is, the working equipment can rotate around the circumference of the main frame 2, so as to meet the working needs of the working equipment at different circumferential positions of the open tunneling machine.

[0044] The gear rotation mechanism 30 includes a base 31 for fixing the working equipment, a gear 32 meshing with the gear ring structure 11, and a drive motor 33 connected to the gear 32. The drive motor 33 drives the gear 32 to rotate so as to drive the working equipment supported on the base 31 to rotate around the gear ring structure 11.

[0045] The base 31 includes a base plate 311 and a transition platform 312 mounted on the upper part of the base plate 311. The transition platform 312 is set higher than the drive motor 33 to provide clearance for the working equipment to adjust its direction and to prevent the working equipment from interfering with the drive motor 33.

[0046] The gear 32 meshes with the gear ring 112 to ensure the stability of the gear 32 when rotating relative to the gear ring 112.

[0047] like Figure 4 and Figure 5 As shown, the gear rotation mechanism 30 also includes a pair of connecting structures 34 fixed to the lower part of the base 31. The base 31 and the connecting structures 34 form a receiving space for accommodating part of the gear ring structure 11. When the drive motor 33 drives the gear 32 to rotate relative to the gear ring 112, the connecting structures 34 support and limit the gear ring structure 11, preventing the gear ring structure 11 from rolling or shaking laterally when subjected to force, and ensuring stable meshing between the gear 32 and the gear ring 112.

[0048] The connection structure 34 includes a longitudinal plate 341 connected to the bottom of the base 31 and a mounting plate 342 installed on the bottom of the longitudinal plate 341. The longitudinal plate 341 has a bottom surface, and the mounting plate 342 is arranged outward relative to the bottom surface. The upper end of the reinforcing ring plate 122 is in contact with the bottom surface, and the side end of the reinforcing ring plate 122 is in contact with the mounting plate 342, so that the gear ring assembly 10 and the gear rotation mechanism 30 are combined into a whole, thereby improving the structural strength and stability of the rotary work platform 1. In this application, such as Figure 1 and Figure 2 As shown, the gear rotation mechanism 30 also includes a plurality of main support wheels 35 and a plurality of guide wheels 36 respectively mounted on the connecting structure 34. The main support wheels 35 are respectively attached to the upper and lower ends of the reinforcing ring plate 122 and bear the weight of the entire gear rotation mechanism 30 and the working equipment.

[0049] The guide wheel 36 is fixedly installed on the mounting plate 342. The guide wheel 36 is located on both sides of the main support wheel 35 in the lateral direction and is respectively attached to the side of the reinforcing ring plate 122 in the axial direction. When the gear 32 rotates relative to the gear ring 122, it plays a guiding and limiting role. On the one hand, it can improve the smoothness of rotation, and on the other hand, it can prevent the gear ring structure 1 from rolling or shaking laterally when subjected to force, ensuring stable meshing between the gear 21 and the gear ring 111.

[0050] like Figure 3As shown, the rotary work platform 1 also includes a mounting seat 50 fixed to the fixed ring plate 121 for mounting the wheel 21, and a support rib 60 fixedly connecting the mounting seat 50 and the fixed ring plate 121. Four mounting seats 50 and four support ribs 60 are provided, each corresponding to one of the wheels 21. The support ribs 60 and the wheel 21 are located on both sides of the mounting seat 50, respectively, to enhance the structural strength of the rotary work platform 1.

[0051] The rotary work platform 1 also includes a personnel platform 70 fixedly installed on the fixed ring plate 121, such as Figure 1 and Figure 3 As shown, the standing platform 70 is mounted on the fixed ring plate 121 via a flange and forms an integral part with the gear ring assembly 10, achieving the effect of moving relative to the main frame 2 at the same time.

[0052] The manned platform 70 is located behind the gear rotating mechanism 30, which facilitates construction personnel to operate the work equipment on the manned platform.

[0053] This application also provides an open-type tunneling machine, such as Figure 6 and Figure 7 As shown, the open-face tunneling machine includes a main frame 2 and the aforementioned rotary working platform 1 for the open-face tunneling machine. The rotary working platform 1 is used to connect the main frame 2 and the working equipment. Specifically, the guide structure 22 is fixed to the main frame 2 by steel plates. The wheels 21 drive the gear ring assembly 10, the gear rotating mechanism 30, and the working equipment installed on the gear rotating mechanism 30 to move back and forth relative to the main frame 2, so as to flexibly move the position of the working platform according to the construction needs.

[0054] In summary, the rotary working platform 1 for an open-face tunneling machine of this application, through the cooperation of the gear ring assembly 10, the gear rotation mechanism 30, and the translation mechanism 20, enables the working equipment to not only rotate around the circumference of the open-face tunneling machine, but also to translate back and forth relative to the open-face tunneling machine, providing a flexible working space for the working equipment and meeting the diverse operational needs of the working equipment.

[0055] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0056] The detailed descriptions listed above are merely specific illustrations of feasible embodiments of this application and are not intended to limit the scope of protection of this application. All equivalent embodiments or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
