Description

Technical Field

[0001] This invention relates to the field of tunneling machine technology, and more specifically, to a beam support assembly and a tunneling machine. Background Technology

[0002] In related technologies, the beam support device is installed on the cutting section. When carrying out beam support operations, the steel beam to be supported is placed in the installation groove of the beam support device. The two ends of the steel beam are manually supported to keep it stable. The hydraulic cylinder is controlled to lift the beam support device, and then the steel beam can be supported to the top of the working roadway for beam erection operations.

[0003] In the process of developing this invention, the inventors discovered at least the following problems in the related technology: The beam support and hydraulic cylinders are connected to the cutting section. Before other processes can be performed after completing the beam support operation, the beam support and hydraulic cylinders usually need to be disassembled from the cutting section, which is cumbersome and affects work efficiency. Furthermore, the beam support uses a single hydraulic cylinder for support, and the hydraulic cylinder is located in the middle of the beam support, resulting in low lifting capacity and the steel beam being prone to deflection during the lifting process. Summary of the Invention

[0004] In order to solve or improve at least one of the above-mentioned technical problems, one object of the present invention is to provide a beam support assembly.

[0005] Another object of the present invention is to provide a tunneling machine having the above-described beam support assembly.

[0006] To achieve the above objectives, a first aspect of the present invention provides a beam support assembly for detachable connection with a tunneling machine. The beam support assembly includes: a base for detachable connection with a cutting section; a telescopic mechanism, one end of which is rotatably connected to the base; at least two first driving members, at least one first driving member being disposed on one side of the telescopic mechanism and at least one first driving member being disposed on the other side of the telescopic mechanism, one end of the first driving member being rotatably connected to the base and the other end of the first driving member being rotatably connected to the telescopic mechanism, the first driving member being used to change the angle between the telescopic mechanism and the base so that the other end of the telescopic mechanism moves away from or closer to the base; and a slotting mechanism connected to the other end of the telescopic mechanism, the slotting mechanism having a slot for placing the object to be supported.

[0007] According to the technical solution of the beam support assembly provided by the present invention, the other components of the beam support assembly (telescopic mechanism, first drive member, and support groove mechanism) are directly or indirectly connected to the base, thereby integrating the beam support assembly into a single unit. This facilitates quick installation or removal of the beam support assembly from the cutting section by workers, simplifying the installation and disassembly process and improving work efficiency. Furthermore, each side of the telescopic mechanism is equipped with at least one first drive member. This design not only enhances the lifting capacity of the beam support assembly but also largely prevents the steel beam from deflecting during the lifting process, resulting in a smoother lifting process and higher safety performance.

[0008] Specifically, the beam support assembly includes a base, a telescopic mechanism, at least two first drive components, and a mounting mechanism. The base is used for detachable connection to the cutting section of the tunneling machine. The base primarily serves as a mounting carrier. Other components in the beam support assembly (telescopic mechanism, first drive components, and mounting mechanism) are directly or indirectly connected to the base, thus integrating the beam support assembly into a single unit. This facilitates quick installation and removal of the beam support assembly from the cutting section, simplifying the installation and disassembly process and improving work efficiency. Optionally, the base can be a plate or block structure, and its shape can be arbitrary. The beam support assembly is a one-piece design, allowing direct assembly to the cutting section of the tunneling machine using fasteners. When not in use or under maintenance, it can be completely removed from the cutting section, making it convenient, quick, and easy to maintain and repair.

[0009] Furthermore, one end of the telescopic mechanism is rotatably connected to the base. Optionally, the base is provided with at least one first ear plate. One end of the telescopic mechanism is rotatably connected to the first ear plate via a fourth pin. The telescopic mechanism can rotate relative to the base about the axis of the fourth pin. The number of first ear plates can be one, two, or more, and the first ear plates can be flexibly set according to actual needs. Optionally, the telescopic mechanism can extend and retract along its length to change its overall length. Optionally, the telescopic mechanism can perform two-stage or multi-stage extension and retraction. By setting a telescopic mechanism, the flexibility of the beam support assembly is improved to adapt to different roadway heights, making it more versatile and easier to deliver the object to be supported to the target position. Optionally, the object to be supported is a steel beam or a composite beam.

[0010] Furthermore, the number of first driving components is at least two; that is, there can be one, two, or more first driving components. Considering the support effect on the telescopic mechanism, space occupation, cost, and other factors, the first driving components are flexibly set according to actual needs. Furthermore, at least one first driving component is located on one side of the telescopic mechanism, and at least one first driving component is located on the other side. Each side of the telescopic mechanism has at least one first driving component to ensure that the telescopic mechanism does not deviate, the force is evenly distributed, and the operation is stable. Compared to using only one first driving component, this method can lift a heavier composite beam. Optionally, the first driving component is a lifting cylinder.

[0011] Furthermore, one end of the first driving member is rotatably connected to the base. The other end of the first driving member is rotatably connected to the telescopic mechanism. The first driving member is used to change the angle between the telescopic mechanism and the base, so that the other end of the telescopic mechanism moves away from or closer to the base. Since each side of the telescopic mechanism is provided with at least one first driving member, this design, compared with the traditional single-cylinder support method, can improve the lifting capacity of the beam support assembly and largely avoid the steel beam deflection during the lifting process, making the entire lifting process smoother and safer.

[0012] Optionally, the base is provided with at least one second ear plate. One end of the first driving member is rotatably connected to the second ear plate via a fourth pin. The first driving member can rotate relative to the base about the axis of the fourth pin. The number of second ear plates can be one, two, or more, and can be flexibly arranged according to actual needs. Optionally, the telescopic mechanism is provided with at least two mounting parts. The number of mounting parts is at least two, that is, there can be two or more mounting parts, and the mounting parts can be flexibly arranged according to actual needs. At least one mounting part is located on one side of the telescopic mechanism, and at least one mounting part is located on the other side of the telescopic mechanism. The telescopic mechanism is rotatably connected to the other end of the first driving member through the mounting parts.

[0013] Furthermore, the other end of the support mechanism is connected to the telescopic mechanism. The support mechanism has a slot for placing the component to be lifted. By setting up the support mechanism, the lifting process of the beam support assembly on the component to be lifted can be made more stable.

[0014] In the technical solution defined by this invention, all components of the beam support assembly except the base (the telescopic mechanism, the first drive component, and the support slot mechanism) are directly or indirectly connected to the base, thus integrating the beam support assembly into a single unit. This facilitates quick installation or removal of the beam support assembly from the cutting section by workers, simplifying the installation and disassembly process and improving work efficiency. Furthermore, each side of the telescopic mechanism is equipped with at least one first drive component. This design not only enhances the lifting capacity of the beam support assembly but also significantly reduces the risk of beam deflection during lifting, resulting in a smoother lifting process and higher safety performance.

[0015] In addition, the technical solution provided by the present invention may also have the following additional technical features:

[0016] In the above technical solution, the bracket mechanism includes: a mounting frame connected to the other end of the telescopic mechanism; a swing body rotatably disposed on the mounting frame, the swing body rotating relative to the mounting frame around a first rotation axis; a rotary body rotatably disposed on the swing body, the rotary body rotating relative to the swing body around a second rotation axis, the included angle between the second rotation axis and the first rotation axis being non-zero, and the bracket being disposed on the rotary body.

[0017] In this technical solution, the bracket mechanism includes a mounting frame, a swing body, and a rotating body. Specifically, the mounting frame of the bracket mechanism is connected to the other end of the telescopic mechanism. Optionally, the mounting frame and the telescopic mechanism are detachably connected, facilitating the disassembly and assembly of the bracket mechanism by workers, and aiding in maintenance or replacement. The mounting frame primarily serves as a mounting carrier. The mounting frame and the telescopic mechanism are relatively fixed.

[0018] Furthermore, the swing body is rotatably mounted on the mounting frame. The swing body can rotate relative to the mounting frame about a first rotation axis. Optionally, the bracket mechanism also includes a first pin. The first pin passes through the swing body and the mounting frame. The axis of the first pin is the first rotation axis. The swing body can rotate relative to the mounting frame about the axis of the first pin.

[0019] Furthermore, the rotating body is rotatably mounted on the swinging body. The rotating body can rotate relative to the swinging body about a second rotation axis. Optionally, the support mechanism also includes a second pin. The second pin passes through the rotating body and the swinging body. The axis of the second pin is the second rotation axis. The rotating body can rotate relative to the swinging body about the axis of the second pin. Furthermore, a support slot is provided on the rotating body, and the support slot is used to place the part to be lifted. Furthermore, the angle between the second rotation axis and the first rotation axis is non-zero, that is, the second rotation axis is neither parallel nor coincident with the first rotation axis, ensuring that the rotating body has multiple rotational degrees of freedom relative to the mounting frame. The rotating body can rotate relative to the mounting frame in multiple rotational directions, such as rotating up and down or swinging left and right. The part to be lifted can achieve 360-degree rotation through the support mechanism, and the operator can adjust the posture or angle of the part to be lifted as needed, so that the beam support assembly can complete the lifting work under various working conditions.

[0020] In the above technical solution, the swing body is rotatably connected to the mounting frame via a first pin, the axis of which is the first rotation axis, and the swing body rotates relative to the mounting frame around the axis of the first pin; the rotary body is rotatably connected to the swing body via a second pin, the axis of which is the second rotation axis, and the rotary body rotates relative to the swing body around the axis of the second pin.

[0021] In this technical solution, the component to be lifted can rotate relative to the mounting frame in a first rotation direction through the rotational connection between the swinging body and the mounting frame. Through the rotational connection between the rotary body and the swinging body, the component to be lifted can rotate relative to the mounting frame in a second rotation direction. By setting a support mechanism, the component to be lifted can rotate up and down and / or swing left and right relative to the telescopic mechanism, thus smoothly completing the lifting work under various working conditions. Optionally, a second pin passes through the first pin, and the second pin can rotate relative to the first pin. The axis of the second pin is coplanar with and perpendicular to the axis of the first pin. This design improves the integration of the support mechanism, increases space utilization, and makes the entire lifting process smoother.

[0022] In the above technical solution, the support mechanism further includes a limiting part, which is connected to the rotating body. The limiting part is located at the opening of the support groove and is used to limit the part to be supported in the support groove.

[0023] In this technical solution, the support mechanism also includes a limiting part. Specifically, the limiting part is connected to the rotating body. The limiting part is located at the opening of the support slot. By setting the limiting part, the part to be lifted within the support slot can be limited to prevent it from detaching from the slot during lifting, thus improving installation performance. Optionally, the limiting part and the rotating body are detachably connected, facilitating disassembly and assembly by workers for maintenance or replacement. Optionally, the limiting part is a limiting hook or a limiting plate.

[0024] In the above technical solution, the bracket mechanism further includes: a third pin, which passes through the mounting frame and the swing body. The axis of the third pin does not coincide with the first rotation axis. The third pin is used to limit the rotation of the swing body relative to the mounting frame.

[0025] In this technical solution, the support mechanism also includes a third pin. Specifically, the third pin passes through the mounting frame and the swing body. The axis of the third pin does not coincide with the first rotation axis. Optionally, the axis of the third pin does not coincide with the axis of the first pin. The third pin is used to limit the rotation of the swing body relative to the mounting frame. When the third pin is not installed, the swing body can freely rotate relative to the mounting frame around the axis of the first pin. When the swing body and the mounting frame are at a suitable angle, the operator passes the third pin through the mounting frame and the swing body to limit the swing body. This design can change and control the posture of the object to be supported, thereby successfully completing the support work.

[0026] In the above technical solution, the swing body is provided with a first positioning hole, and the mounting bracket is provided with multiple second positioning holes. During the rotation of the swing body relative to the mounting bracket, the center line of the first positioning hole coincides with the center line of the multiple second positioning holes in sequence, and the third pin passes through one of the second positioning holes and the first positioning hole.

[0027] In this technical solution, by setting a first positioning hole and multiple second positioning holes, the operator passes the third pin through the first positioning hole and any one of the multiple second positioning holes, creating an angle between the swing body and the mounting frame. Depending on the actual needs, the first positioning hole on the swing body is matched with one of the multiple second positioning holes on the mounting frame to ensure a suitable angle between the swing body and the mounting frame, resulting in a smoother lifting process and higher safety performance.

[0028] In the above technical solution, the telescopic mechanism includes: an outer cylinder, one end of which is rotatably connected to the base, and the end of the first driving member away from the base is rotatably connected to the outer cylinder; a middle cylinder, which is movably inserted through the other end of the outer cylinder; an inner cylinder, which is movably inserted through the middle cylinder and is connected to the support mechanism; and a second driving member, one end of which is rotatably connected to the base and the other end of which is rotatably connected to the inner cylinder, the second driving member being used to change the overall length of the telescopic mechanism.

[0029] In this technical solution, the telescopic mechanism includes an outer cylinder, a middle cylinder, an inner cylinder, and a second driving component. One end of the outer cylinder is rotatably connected to the base. Optionally, one end of the outer cylinder is rotatably connected to a first lug on the base via a fourth pin. The outer cylinder of the telescopic mechanism can rotate relative to the base around the axis of the fourth pin. Optionally, a mounting part is located on the outer cylinder. The outer cylinder is rotatably connected to the first driving component via the mounting part. Optionally, the mounting part and the outer cylinder are detachably connected, facilitating disassembly and assembly by workers, and aiding in maintenance or replacement; alternatively, the mounting part and the outer cylinder are fixed together by welding, simplifying the processing method; or alternatively, the mounting part and the outer cylinder are an integral structure, which, compared to post-processing, offers better mechanical properties, higher connection strength, and helps reduce the number of parts, improving assembly efficiency.

[0030] Furthermore, the middle cylinder is movably inserted through the other end of the outer cylinder. The middle cylinder can move relative to the outer cylinder. Optionally, the other end of the outer cylinder is provided with a first slide rail, through which the middle cylinder passes. The middle cylinder can move relative to the outer cylinder along the first slide rail. Furthermore, the inner cylinder is movably inserted through the middle cylinder. The inner cylinder can move relative to the middle cylinder. Optionally, the middle cylinder is provided with a second slide rail, through which the inner cylinder passes. The inner cylinder can move relative to the middle cylinder along the second slide rail. Furthermore, the inner cylinder is connected to the support mechanism. Optionally, the inner cylinder is connected to the mounting bracket of the support mechanism. The middle cylinder can move relative to the outer cylinder; the inner cylinder can move relative to the middle cylinder. The telescopic mechanism's outer cylinder, middle cylinder, and inner cylinder achieve two-stage telescopic movement, which facilitates a smoother delivery of the object to be supported to the target position.

[0031] Furthermore, one end of the second driving member is rotatably connected to the base, and the other end is rotatably connected to the inner cylinder. Optionally, the base is provided with at least one third ear plate. One end of the second driving member is rotatably connected to the third ear plate via a fifth pin. The second driving member can rotate relative to the base about the axis of the fifth pin. The number of third ear plates can be one, two, or more, and can be flexibly set according to actual needs. By setting the second driving member, the inner cylinder can be driven to move relative to the outer cylinder to extend the overall length of the telescopic mechanism. Optionally, the second driving member is a telescopic hydraulic cylinder.

[0032] By setting up a telescopic mechanism, the telescopic function can be realized to meet the different needs of various working conditions. This helps to expand the application range of the beam support assembly, reduce the workload of order-based design, and enable the beam support assembly to be mass-produced.

[0033] The above technical solution also includes: at least two limiting blocks, the limiting blocks being connected to the base, at least one limiting block being located on one side of the telescopic mechanism, and at least one limiting block being located on the other side of the telescopic mechanism.

[0034] In this technical solution, the beam support assembly also includes at least two limiting blocks. Specifically, the limiting blocks are connected to the base. There is at least one limiting block; that is, there can be one, two, or more limiting blocks, which can be flexibly set according to actual needs. At least one limiting block is located on one side of the telescopic mechanism, and at least one limiting block is located on the other side of the telescopic mechanism. By setting the limiting blocks, on the one hand, they can guide the telescopic mechanism during its rotation relative to the base; on the other hand, they can prevent the telescopic mechanism from moving left and right to a certain extent, effectively avoiding misalignment and improving safety performance.

[0035] The above technical solution also includes: an anti-slip guard plate, which is located on the side of the outer cylinder away from the base.

[0036] In this technical solution, the beam support assembly also includes an anti-slip guard plate. Specifically, the anti-slip guard plate is located on the side of the outer cylinder facing away from the base. Optionally, when the beam support assembly is in the retracted state, the telescopic mechanism can be placed completely horizontally, at which time workers can perform other operations on the anti-slip guard plate. Optionally, the anti-slip guard plate is made of anti-slip material. Optionally, the surface of the anti-slip guard plate has an anti-slip layer made of anti-slip material. Optionally, the surface of the anti-slip guard plate has anti-slip texture. By setting up an anti-slip platform, on the one hand, it can be used as a work platform when the telescopic mechanism is placed horizontally, providing an anti-slip function so that workers can work with the help of the anti-slip guard plate; on the other hand, it can cover and protect the telescopic mechanism and other components (such as drive components and ear plates) located below.

[0037] A second aspect of the present invention provides a tunneling machine, comprising: a cutting section; and a beam support assembly as described in any of the above technical solutions, wherein the base of the beam support assembly is detachably connected to the cutting section.

[0038] According to the technical solution of the tunneling machine of the present invention, the tunneling machine includes a cutting section and a beam support assembly as described in any of the above technical solutions. The base of the beam support assembly is detachably connected to the cutting section. The base mainly serves as a mounting carrier. Other components of the beam support assembly (telescopic mechanism, first drive component, and support groove mechanism) are directly or indirectly connected to the base, thus integrating the beam support assembly into a single unit. This facilitates quick installation or removal of the beam support assembly from the cutting section by operators, simplifying the installation and disassembly process and improving work efficiency. The beam support assembly is an integral design, allowing direct assembly to the cutting section of the tunneling machine using fasteners. It can also be easily and quickly removed from the cutting section when not in use or during maintenance.

Detailed Implementation

[0056] To better understand the above-described objectives, features, and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0057] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0058] The following reference Figures 1 to 13 The beam support assembly 100 and the tunneling machine 200 provided according to some embodiments of the present invention are described.

[0059] In one embodiment of the invention, such as Figure 1 , Figure 2 and Figure 8 As shown, the beam support assembly 100 includes a base 110, a telescopic mechanism 120, at least two first driving members 130, and a support slot mechanism 140. The base 110 is detachably connected to the cutting section 210 of the tunneling machine 200. The base 110 primarily serves as a mounting carrier. All other components of the beam support assembly 100 (excluding the base 110, the telescopic mechanism 120, the first driving members 130, and the support slot mechanism 140) are directly or indirectly connected to the base 110, thus integrating the beam support assembly 100 into a single unit. This facilitates quick installation and removal of the beam support assembly 100 from the cutting section 210, simplifying the installation and removal process and improving work efficiency. Optionally, the base 110 can be a plate-like or block-like structure, and its shape can be arbitrary. The beam support assembly 100 is an integral design that can be directly assembled onto the cutting section 210 of the tunneling machine 200 using fasteners. When not in use or under maintenance, it can be completely removed from the cutting section 210, which is convenient, quick, and easy to maintain and repair.

[0060] Further, one end of the telescopic mechanism 120 is rotatably connected to the base 110. Optionally, the base 110 is provided with at least one first ear plate. One end of the telescopic mechanism 120 is rotatably connected to the first ear plate via a fourth pin. The telescopic mechanism 120 can rotate relative to the base 110 about the axis of the fourth pin. The number of first ear plates can be one, two, or more, and the first ear plates can be flexibly set according to actual needs. Optionally, the telescopic mechanism 120 can extend and retract along its length to change its overall length. Optionally, the telescopic mechanism 120 can perform two-stage or multi-stage extension and retraction. By setting the telescopic mechanism 120, the flexibility of the beam support assembly 100 is improved to adapt to different roadway heights, making it more versatile and easier to deliver the object to be supported to the target position. Optionally, the object to be supported is a steel beam or a composite beam.

[0061] Furthermore, the number of first driving components 130 is at least two; that is, there can be one, two, or more first driving components 130. Considering the support effect on the telescopic mechanism 120, the space occupied, cost, and other factors, the first driving components 130 are flexibly configured according to actual needs. Furthermore, at least one first driving component 130 is located on one side of the telescopic mechanism 120, and at least one first driving component 130 is located on the other side of the telescopic mechanism 120. With at least one first driving component 130 on each side of the telescopic mechanism 120, it is possible to ensure that the telescopic mechanism 120 does not become biased, the force is evenly distributed, and the operation is stable. Compared to using only one first driving component 130, this allows for the lifting of heavier composite beams. Optionally, the first driving component 130 is a lifting cylinder.

[0062] Furthermore, one end of the first driving member 130 is rotatably connected to the base 110. The other end of the first driving member 130 is rotatably connected to the telescopic mechanism 120. The first driving member 130 is used to change the angle between the telescopic mechanism 120 and the base 110, so that the other end of the telescopic mechanism 120 moves away from or closer to the base 110. Since each side of the telescopic mechanism 120 is provided with at least one first driving member 130, this design, compared with the traditional single-cylinder support method, can improve the lifting capacity of the beam support assembly 100 on the one hand, and on the other hand, can largely avoid the deflection of the steel beam during the lifting process, making the entire lifting process more stable and safer.

[0063] Optionally, the base 110 is provided with at least one second ear plate. One end of the first driving member 130 is rotatably connected to the second ear plate via a fourth pin. The first driving member 130 is capable of rotating relative to the base 110 about the axis of the fourth pin. The number of second ear plates can be one, two, or more, and can be flexibly arranged according to actual needs. Optionally, the telescopic mechanism 120 is provided with at least two mounting portions 125. The number of mounting portions 125 is at least two, that is, there can be two or more mounting portions 125, and the mounting portions 125 can be flexibly arranged according to actual needs. At least one mounting portion 125 is provided on one side of the telescopic mechanism 120, and at least one mounting portion 125 is provided on the other side of the telescopic mechanism 120. The telescopic mechanism 120 is rotatably connected to the other end of the first driving member 130 via the mounting portions 125.

[0064] Furthermore, the support mechanism 140 is connected to the other end of the telescopic mechanism 120. The support mechanism 140 has a support slot 1431 for placing the component to be supported. By providing the support mechanism 140, the process of the beam support assembly 100 supporting the component to be supported can be made more stable.

[0065] In the technical solution defined by this invention, all components of the beam support assembly 100 except for the base 110 (telescopic mechanism 120, first drive member 130, and support groove mechanism 140) are directly or indirectly connected to the base 110, thereby integrating the beam support assembly 100 into a single unit. This facilitates quick installation or removal of the beam support assembly 100 from the cutting section 210 by workers, simplifying the installation and disassembly process and improving work efficiency. Furthermore, each side of the telescopic mechanism 120 is equipped with at least one first drive member 130. This design not only enhances the lifting capacity of the beam support assembly 100 but also significantly reduces the risk of beam deflection during lifting, resulting in a smoother and safer lifting process.

[0066] In one embodiment of the invention, such as Figure 1 , Figure 2 and Figure 9 As shown, the bracket mechanism 140 includes a mounting frame 141, a swing body 142, and a rotating body 143. Specifically, the mounting frame 141 of the bracket mechanism 140 is connected to the other end of the telescopic mechanism 120. Optionally, the mounting frame 141 and the telescopic mechanism 120 are detachably connected, facilitating the disassembly and assembly of the bracket mechanism 140 by personnel, which is beneficial for maintenance or replacement. The mounting frame 141 mainly serves as a mounting carrier. The mounting frame 141 is fixed relative to the telescopic mechanism 120.

[0067] Furthermore, the swing body 142 is rotatably mounted on the mounting bracket 141. The swing body 142 is capable of rotating relative to the mounting bracket 141 about a first rotation axis. Optionally, as... Figure 1 , Figure 2 and Figure 9 As shown, the bracket mechanism 140 also includes a first pin 144. The first pin 144 passes through the swing body 142 and the mounting bracket 141. The axis of the first pin 144 is the first rotation axis. The swing body 142 can rotate relative to the mounting bracket 141 about the axis of the first pin 144.

[0068] Further, the rotating body 143 is rotatably disposed on the swing body 142. The rotating body 143 can rotate relative to the swing body 142 about a second rotation axis. Optionally, the support mechanism 140 also includes a second pin 145. The second pin 145 passes through the rotating body 143 and the swing body 142. The axis of the second pin 145 is the second rotation axis. The rotating body 143 can rotate relative to the swing body 142 about the axis of the second pin 145. Further, a support slot 1431 is disposed on the rotating body 143, and the support slot 1431 is used to place the part to be supported. Further, the angle between the second rotation axis and the first rotation axis is non-zero, that is, the second rotation axis is neither parallel nor coincident with the first rotation axis, ensuring that the rotating body 143 has multiple rotational degrees of freedom relative to the mounting frame 141, and the rotating body 143 can rotate relative to the mounting frame 141 in multiple rotational directions, such as rotating up and down or swinging left and right. The component to be lifted can rotate 360 ​​degrees through the support mechanism 140. The operator can adjust the posture or angle of the component to be lifted as needed so that the beam support assembly 100 can complete the lifting work under various working conditions.

[0069] Furthermore, the swing body 142 is rotatably connected to the mounting frame 141 via a first pin 144, the axis of which is a first rotation axis, and the swing body 142 rotates relative to the mounting frame 141 around the axis of the first pin 144; the rotating body 143 is rotatably connected to the swing body 142 via a second pin 145, the axis of which is a second rotation axis, and the rotating body 143 rotates relative to the swing body 142 around the axis of the second pin 145. Through the rotatable connection between the swing body 142 and the mounting frame 141, the part to be lifted can rotate relative to the mounting frame 141 in a first rotation direction. Through the rotatable connection between the rotating body 143 and the swing body 142, the part to be lifted can rotate relative to the mounting frame 141 in a second rotation direction. By providing the support mechanism 140, the part to be lifted can rotate up and down and / or swing left and right relative to the telescopic mechanism 120, so that the lifting work can be completed smoothly under various working conditions. Optionally, as... Figure 11As shown, the second pin 145 passes through the first pin 144, and the second pin 145 can rotate relative to the first pin 144. The axis of the second pin 145 is coplanar with the axis of the first pin 144 and perpendicular to each other. This design improves the integration of the support mechanism 140, increases space utilization, and makes the entire lifting process smoother.

[0070] Furthermore, such as Figure 1 , Figure 2 and Figure 9 As shown, the bracket mechanism 140 also includes a limiting part 146. Specifically, the limiting part 146 is connected to the rotating body 143. The limiting part 146 is located at the opening of the bracket 1431. By providing the limiting part 146, the component to be lifted within the bracket 1431 can be limited to prevent it from detaching from the bracket 1431 during lifting, thus improving installation performance. Optionally, the limiting part 146 is detachably connected to the rotating body 143, facilitating disassembly and assembly by personnel for maintenance or replacement. Optionally, the limiting part 146 can be a limiting hook or a limiting plate.

[0071] Furthermore, such as Figure 1 , Figure 2 and Figure 9 As shown, the support mechanism 140 also includes a third pin 147. Specifically, the third pin 147 passes through the mounting frame 141 and the swing body 142. The axis of the third pin 147 does not coincide with the first rotation axis. Optionally, the axis of the third pin 147 does not coincide with the axis of the first pin 144. The third pin 147 is used to limit the rotation of the swing body 142 relative to the mounting frame 141. When the third pin 147 is not installed, the swing body 142 can freely rotate relative to the mounting frame 141 around the axis of the first pin 144. When the swing body 142 and the mounting frame 141 are at a suitable angle, the operator passes the third pin 147 through the mounting frame 141 and the swing body 142 to limit the swing body 142. This design can change and control the posture of the object to be supported, thereby successfully completing the lifting work.

[0072] Furthermore, such as Figure 12As shown, the swing body 142 has a first positioning hole 1421, and the mounting frame 141 has multiple second positioning holes 1411. During the rotation of the swing body 142 relative to the mounting frame 141, the center line of the first positioning hole 1421 successively coincides with the center lines of the multiple second positioning holes 1411. The third pin 147 passes through one of the second positioning holes 1411 and the first positioning hole 1421. By setting the first positioning hole 1421 and multiple second positioning holes 1411, the operator can pass the third pin 147 through the first positioning hole 1421 and any one of the multiple second positioning holes 1411, resulting in an angle between the swing body 142 and the mounting frame 141. According to actual needs, the first positioning hole 1421 on the swing body 142 can be matched with one of the multiple second positioning holes 1411 on the mounting frame 141 to make the swing body 142 and the mounting frame 141 at a suitable angle, making the entire lifting process more stable and safer.

[0073] In one embodiment of the invention, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the telescopic mechanism 120 includes an outer cylinder 121, a middle cylinder 122, an inner cylinder 123, and a second driving member 124. One end of the outer cylinder 121 is rotatably connected to the base 110. Optionally, one end of the outer cylinder 121 is rotatably connected to a first ear plate on the base 110 via a fourth pin. The outer cylinder 121 of the telescopic mechanism 120 can rotate relative to the base 110 about the axis of the fourth pin. Optionally, a mounting part 125 is provided on the outer cylinder 121. The outer cylinder 121 is rotatably connected to the first driving member 130 via the mounting part 125. Optionally, the mounting part 125 and the outer cylinder 121 are detachably connected, facilitating disassembly and assembly by workers, and aiding in maintenance or replacement; alternatively, the mounting part 125 and the outer cylinder 121 are fixed relative to each other by welding, simplifying the processing method; or alternatively, the mounting part 125 and the outer cylinder 121 are an integral structure, which, compared to post-processing, offers better mechanical properties, higher connection strength, and helps reduce the number of parts and improve assembly efficiency.

[0074] Further, the middle cylinder 122 is movably inserted through the other end of the outer cylinder 121. The middle cylinder 122 is movable relative to the outer cylinder 121. Optionally, the other end of the outer cylinder 121 is provided with a first slide rail, through which the middle cylinder 122 passes. The middle cylinder 122 is movable relative to the outer cylinder 121 along the first slide rail. Further, the inner cylinder 123 is movably inserted through the middle cylinder 122. The inner cylinder 123 is movable relative to the middle cylinder 122. Optionally, the middle cylinder 122 is provided with a second slide rail, through which the inner cylinder 123 passes. The inner cylinder 123 is movable relative to the middle cylinder 122 along the second slide rail. Further, the inner cylinder 123 is connected to the support mechanism 140. Optionally, the inner cylinder 123 is connected to the mounting bracket 141 of the support mechanism 140. The middle cylinder 122 is movable relative to the outer cylinder 121; the inner cylinder 123 is movable relative to the middle cylinder 122. The outer cylinder 121, middle cylinder 122 and inner cylinder 123 of the telescopic mechanism 120 achieve two-stage telescopic movement, which helps to deliver the object to be lifted to the target position more smoothly.

[0075] Further, one end of the second driving member 124 is rotatably connected to the base 110, and the other end of the second driving member 124 is rotatably connected to the inner cylinder 123. Optionally, the base 110 is provided with at least one third ear plate. One end of the second driving member 124 is rotatably connected to the third ear plate via a fifth pin. The second driving member 124 can rotate relative to the base 110 about the axis of the fifth pin. The number of third ear plates can be one, two, or more, and can be flexibly set according to actual needs. By setting the second driving member 124, the inner cylinder 123 can be driven to move relative to the outer cylinder 121 by the overall length of the telescopic mechanism 120. Optionally, the second driving member 124 is a telescopic hydraulic cylinder.

[0076] By setting the telescopic mechanism 120, the telescopic function can be realized to meet the different needs of various working conditions. This helps to expand the application range of the beam support assembly 100, reduce the workload of order-based design, and enable the beam support assembly 100 to be mass-produced.

[0077] Furthermore, such as Figure 3 As shown, the beam support assembly 100 also includes at least two limiting blocks 150. Specifically, the limiting blocks 150 are connected to the base 110. The number of limiting blocks 150 is at least one; that is, there can be one, two, or more limiting blocks 150, which can be flexibly set according to actual needs. At least one limiting block 150 is located on one side of the telescopic mechanism 120, and at least one limiting block 150 is located on the other side of the telescopic mechanism 120. By setting the limiting blocks 150, on the one hand, they can guide the telescopic mechanism 120 during its rotation relative to the base 110; on the other hand, they can prevent the telescopic mechanism 120 from moving left and right to a certain extent, effectively avoiding misalignment and improving safety performance.

[0078] Furthermore, such as Figure 1 and Figure 10 As shown, the beam support assembly 100 also includes an anti-slip guard plate 160. Specifically, the anti-slip guard plate 160 is located on the side of the outer cylinder 121 opposite to the base 110. Optionally, when the beam support assembly 100 is in the retracted state, the telescopic mechanism 120 can be placed completely horizontally, at which time the operator can perform other operations on the anti-slip guard plate 160. Optionally, the anti-slip guard plate 160 is made of anti-slip material. Optionally, the surface of the anti-slip guard plate 160 is provided with an anti-slip layer, which is made of anti-slip material. Optionally, the surface of the anti-slip guard plate 160 is provided with anti-slip texture. By setting up an anti-slip platform, on the one hand, it can be used as a work platform when the telescopic mechanism 120 is placed horizontally, providing an anti-slip function so that the operator can work with the help of the anti-slip guard plate 160; on the other hand, it can cover and protect the telescopic mechanism 120 and other components (such as the drive unit and ear plate structures) located below.

[0079] In one embodiment of the invention, such as Figure 13 As shown, the tunneling machine 200 includes a cutting section 210 and a beam support assembly 100 as described in any of the above embodiments. The base 110 of the beam support assembly 100 is detachably connected to the cutting section 210. The base 110 mainly serves as a mounting carrier. Other components in the beam support assembly 100 besides the base 110 (telescopic mechanism 120, first drive component 130, and support groove mechanism 140) are directly or indirectly connected to the base 110, thus integrating the beam support assembly 100 into a single unit. This facilitates quick installation or removal of the beam support assembly 100 from the cutting section 210 by operators, simplifying the installation and removal process and improving work efficiency. The beam support assembly 100 is an integral design, allowing it to be directly assembled onto the cutting section 210 of the tunneling machine 200 using fasteners. When not in use or under maintenance, it can be easily and quickly detached from the cutting section 210.
