Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction equipment, and in particular to a multifunctional integrated working arm. Background Art

[0002] During initial tunnel support, arch frame installation is becoming increasingly mechanized, leading to increasingly stringent requirements for the dimensions of the tunnel working surface. When the rock in the tunnel being excavated is relatively soft, severely fractured, and exhibits poor automatic stability, steel arch frames are required for initial support to ensure construction safety. Existing steel arch frame support structures must first be assembled outside the tunnel and then transported to the face for assembly and support using a multi-functional arch frame assembly machine. However, because the arch frame is already formed, the dimensional requirements for the working surface are relatively strict. If the tunnel is underexcavated, the arch frame cannot be installed. Therefore, the underexcavated areas of the tunnel need to be underexcavated to facilitate arch frame installation.

[0003] However, in the prior art, most of the underbreak mechanisms are installed on the arch frame installation booms for performing underbreak processing during arch frame installation. However, such arch frame installation booms include a dragging mechanism and a working platform. The dragging mechanism drags the arch frame, and the underbreak mechanism and the dragging mechanism are simultaneously arranged on the working platform, which greatly compresses the space of the underbreak mechanism, making it impossible for the underbreak mechanism to effectively cover the entire working surface. At the same time, the dragging mechanism and the underbreak mechanism are simultaneously connected to the working platform, which will affect the structural stability of the working platform after long-term operation and reduce the service life of the working platform.

[0004] In addition, a driving member is provided between the working platform and the arm to drive the working platform to move up and down along the arm, so as to move the working platform to a designated position for operation.

[0005] However, in the prior art, most driving members drive the work platform by rotating around the connection point between the driving member and the arm as the origin, driving the work platform to rotate on the vertical plane to achieve up and down displacement. The moving path of the work platform is an arc. When it is necessary to work on the vertical working surface, if the work platform is driven only by the driving member, when the work platform moves up and down, due to the arc-shaped moving path, the displacement difference between the work platform and the working surface will change during movement, causing the work platform to be unable to accurately reach the working surface for operation; or the arm needs to be moved to enable the work platform to move to a precise position for operation.

[0006] Therefore, the working arm in the prior art has room for further improvement. Utility Model Content

[0046] The present application will be described in further detail below with reference to the accompanying drawings. Figures 1 to 4 illustrate.

[0047] The present application provides a multifunctional integrated working arm 1 (hereinafter referred to as the integrated working arm), which is used in tunnel construction equipment. The integrated working arm 1 has both under-excavation processing functions and anchor hole operation functions, and assists in arch frame installation. There is no need to switch to a special anchor hole working platform 13 to perform anchor hole operations after the arch frame is installed, which is conducive to improving work efficiency, simplifying processes, and reducing working time.

[0048] It should be noted that the multifunctional integrated working arm 1 of the present application can be connected to the arch frame trolley to realize multifunctional operation of one vehicle. Before the arch frame is installed on the arch frame trolley, the under-excavation mechanism 14 of the integrated working arm 1 is used to under-excavate the under-excavated parts of the working surface of the tunnel hole, so that the arch frame can be installed in place. After the arch frame is installed, the multifunctional integrated working arm 1 can be switched to perform anchor hole operations, truly realizing multiple uses of one vehicle without the need to switch other equipment, effectively saving working time and improving work efficiency.

[0049] like Figures 1 to 4 As shown, the integrated working arm 1 includes an arm mechanism 11, a working platform 13, a connecting rod driving mechanism 15 and an anchor hole mechanism 12. The anchor hole mechanism 12 is connected to the arm mechanism 11, and the anchor hole mechanism 12 is used for anchor hole operations; one end of the connecting rod driving mechanism 15 is connected to the working platform 13, and the other end is connected to the bottom of the arm mechanism 11. The connecting rod driving mechanism 15 is used to drive the working platform 13 to move up and down along the vertical plane, so as to ensure that the distance between the working platform 13 and the working surface remains consistent during the up and down displacement, which is convenient for precise operation on the working surface. There is no need to move the arm 111 to ensure the consistency of the distance between the working platform 13 and the working surface during the up and down displacement, which can effectively save operation time and improve work efficiency.

[0050] Specifically, such as Figure 3As shown, the connecting rod driving mechanism 15 includes a first connecting rod group 151, a second connecting rod group 152 and a driving member. The first connecting rod group 151 and the second connecting rod group 152 are arranged in parallel between the working platform 13 and the boom 111.

[0051] In this embodiment, the driving member is a linear driving cylinder, and the first connecting rod group 151 includes at least one connecting rod. In this embodiment, the first connecting rod group 151 includes two connecting rods arranged parallel to the horizontal plane; the structure of the second connecting rod group 152 is the same as that of the first connecting rod group 151, and will not be repeated here.

[0052] like Figures 1 to 2 As shown, the integrated working arm 1 also includes an underbreak mechanism 14, which is used to perform underbreak processing on the working surface of the tunnel; one end of the arm mechanism 11 is connected to the equipment body, and the other end is connected to the working platform 13 and the anchor hole mechanism 12, wherein the underbreak mechanism 14 is connected to the side end of the working platform 13, the working platform 13 is connected to the bottom of the front end of the arm mechanism 11, and the anchor hole mechanism 12 is connected to the top of the front end of the arm mechanism 11, thereby staggering the anchor hole mechanism 12 and the underbreak mechanism 14 in the vertical direction to avoid interference between the anchor hole mechanism 12 and the underbreak mechanism 14.

[0053] Further, such as Figures 1 to 4As shown, the multifunctional integrated working arm 1 also includes a first rotating member 16 and a second rotating member 17.

[0054] It should be noted that, in this embodiment, the length of the connecting rod driving mechanism 15 is greater than the length between the first rotating member 16 and the end of the anchor hole mechanism 12. Figure 1 As shown, when the connecting rod driving mechanism 15 is parallel to the arm mechanism 11 and the anchor hole mechanism 12, the connection portion between the connecting rod driving mechanism 15 and the second rotating member 17 exceeds the end of the anchor hole mechanism 12, further reducing the interference between the working platform 13 and the anchor hole mechanism 12.

[0055] Further, such as Figure 3 As shown, the multifunctional integrated working arm 1 also includes a leveling cylinder 18, one end of the leveling cylinder 18 is hinged to the second rotating member 17 at the bottom of the working platform 13, and the other end is hinged to the second fixing member of the connecting rod drive mechanism 15. The leveling cylinder 18 is used to drive the working platform 13 to perform pitching motion relative to the arm mechanism 11, thereby leveling the working platform 13; the leveling cylinder 18 of this embodiment cooperates with the first rotating member 16 and the second rotating member 17, so that the underbreak mechanism 14 and the working platform 13 can achieve a large range of displacement in both the horizontal and vertical planes, thereby improving the operating range of the underbreak mechanism 14.

[0056] At the same time, if Figures 1 to 3As shown, the under-excavation mechanism 14 includes a driving arm 141 and a crushing member 142.

The front end of the driving arm 141 is connected to the crushing member 142; thereby strengthening the connection strength between the crushing member 142 and the working platform 13, so that the working platform 13 is not easily damaged; the driving arm 141 as a whole is close to an L-shape, which includes a connecting part and a driving part, one end of the connecting part is connected to the driving part, and the other end is connected to the working platform 13 and the second rotating member 17. The connecting part structure can be set to be wider , increasing the structural strength with the working platform 13 and the second rotating member 17; the end of the driving part away from the connecting part is connected to the crushing part 142, and the driving part is provided with at least one driving cylinder for driving the crushing part 142 to rotate on the vertical plane, that is, driving the crushing part 142 to make a pitch displacement; the driving arm 141 of this embodiment can drive the crushing part 142 to make fine-tuning pitch displacement in a small range, and cooperate with the leveling cylinder 18 to make a large-scale pitch displacement of the crushing part 142, so that the crushing part 142 can simultaneously achieve a large-scale displacement on the vertical plane and a fine-tuning displacement in a small range, thereby increasing the flexibility and large-scale operability of the under-digging mechanism 14.

[0057] Based on any of the above embodiments, the anchor hole mechanism 12 is further described; Figures 1 to 4 As shown, the anchor hole mechanism 12 includes a propulsion beam 121 and a fixed seat 122, and the integrated working arm 1 includes a slewing assembly. One side of the fixed seat 122 is connected to the side end of the front end of the propulsion beam 121 close to the arm mechanism 11, thereby further expanding the distance between the propulsion beam 121 and the working platform 13 on the horizontal plane and reducing the probability of interference; the other side of the fixed seat 122 is connected to the slewing assembly, and the end of the slewing assembly away from the fixed seat 122 is connected to the front end of the arm mechanism 11. The slewing assembly is used to drive the propulsion beam 121 to rotate on the vertical and horizontal planes.

[0058] Specifically, the rotating assembly includes a third rotating member 123, one end of the third rotating member 123 is connected to the fixed seat 122, and the other end is connected to the arm mechanism 11. The third rotating member 123 is used to drive the anchor hole mechanism 12 to rotate around the first rotation axis, wherein the first rotation axis is perpendicular to the length extension direction of the arm mechanism 11, so that the propulsion beam 121 can be adjusted to the corresponding position to drill anchor holes.

[0059] The rotating assembly includes a fourth rotating member 124, one end of which is connected to the fixing seat 122, and the other end is connected to the arm mechanism 11. The fourth rotating member 124 is used to drive the anchor hole mechanism 12 to rotate around the second rotation axis, and the second rotation axis is parallel to the length extension direction of the arm mechanism 11.

[0060] In another optional embodiment, the rotating assembly also includes a third rotating member 123 and a fourth rotating member 124, the fourth rotating member 124 is connected to the front end of the arm mechanism 11, and the third rotating member 123 is connected to the fourth rotating member 124 through a connecting support, wherein the fourth rotating member 124 is used to drive the third rotating member 123 and the anchor hole mechanism 12 to rotate around the second rotation axis, and the third rotating member 123 is used to drive the anchor hole mechanism 12 to rotate around the first rotation axis, and the first rotation axis and the second rotation axis are perpendicular to each other.

[0061] like Figure 4 As shown, in the present application, although the connecting rod driving mechanism 15 and the anchor rod mechanism are both connected to the front end of the arm mechanism 11, the two are staggered in the vertical and horizontal planes, which can avoid interference between the connecting rod driving mechanism 15 and the anchor rod mechanism.

[0062] Based on any of the above embodiments, the arm mechanism 11 is further described; Figures 1 to 2 、 Figure 4 As shown, the arm mechanism 11 includes an arm 111 and a connecting seat 112. One end of the arm 111 is connected to the connecting seat 112. The connecting seat 112 is provided with a rotation hole. The arm 111 is rotatably connected to the device through the connecting seat 112. Figure 1 As shown, there is an angle θ between the central axis of the rotating hole and the vertical plane, wherein 0°<θ<90°, that is, the connecting seat 112 is connected to the equipment body at an angle, and the connecting seat 112 protrudes from the rear end of the arm 111, so that there is a gap between the arm 111 and the equipment body, thereby avoiding interference between the arm 111 and the equipment body;

[0063] like Figure 1 、 Figure 2 、 Figure 4 As shown, the other end of the boom 111 is connected to the working platform 13 and the anchor hole mechanism 12, wherein the boom 111 is a telescopic structure, and the boom 111 can be telescoped along its length extension direction, thereby adjusting the distance between the working platform 13, the under-break mechanism 14, and the anchor hole mechanism 12 relative to the equipment body, and adjusting the distance between the working platform 13, the under-break mechanism 14, and the anchor hole mechanism 12 and the working surface to improve flexibility.

[0064] Further, such as Figure 1 、 Figure 2 、 Figure 4As shown, the boom mechanism 11 also includes a second driving cylinder 113. The side end of the front end of the second driving cylinder 113 is connected to the boom 111, and the side end of the rear end is connected to the connecting seat 112 or the equipment body. The second driving cylinder 113 is used to drive the arm 141 frame 111 to swing horizontally, thereby adjusting the horizontal displacement of the anchor hole mechanism 12, the under-break mechanism 14, and the working platform 13 within a large range, and cooperating with the leveling cylinder 18 to achieve flexible adjustability of the working platform 13 and the under-break mechanism 14 on the horizontal and vertical planes.

[0065] Furthermore, the multifunctional integrated working arm 1 of the present application further includes a gripping mechanism, which is connected to the working platform 13 and is used to grab the arch frame and assist the multifunctional integrated working arm 1 in installing the arch frame. The gripping mechanism can replace the underbreak mechanism 14, that is, the gripping mechanism is connected to the side of the working platform 13 away from the arm mechanism 11, or it can be set on the side of the working platform 13 so that the gripping mechanism and the underbreak mechanism 14 are simultaneously connected to the working platform 13. A rotating member can be set between the gripping mechanism and the working platform 13 to drive the gripping mechanism to rotate, thereby facilitating adjustment of the working direction.
