[0030] During the tunnel construction process, a supporting structure is needed to support the tunnel to prevent the tunnel wall from collapsing. The current supporting structure is mainly an arch frame structure, and the installation position of the arch frame in the tunnel has strict dimensional control.

[0031] The existing gripper structure is weak in strength and has a small contact surface with the arch frame, which makes it easy to slip, causing a single or several grippers to be subjected to greater force instantaneously, resulting in the gripper breaking. At the same time, a complete arch frame is composed of multiple small arch frames, so the grabbing arch frame needs to be adjusted in multiple postures at the docking point so that the two sections of the arch frame can fit perfectly. The existing gripper structure can only adjust the left and right swing angle of the arch frame within one plane, and the arch frame has no longitudinal deflection angle, which makes it difficult to dock the vertical arch and affects the construction efficiency. Since the span of multiple arch frames is large, it is easy to shake during grabbing, which has a certain impact on the overall structure of the arch frame and the safety of the construction environment.

[0032] Based on the above problems, the embodiment of the utility model provides a tunnel engineering trolley, which is suitable for tunnel construction operations, such as arch erection operations, drilling operations, and grouting operations in tunnels. The tunnel engineering trolley includes a trolley and an arch frame clamping device arranged on the trolley, and the trolley can drive the arch frame clamping device to move and control the arch frame clamping device to complete the arch erection construction operation.

[0033] For details, see Figures 1 to 3 The arch frame clamping device 10 includes a grab arm 100, a driving mechanism 200, an arch frame grabber 300 and a support member 400.

[0034] Among them, the driving mechanism 200 is arranged on the grab arm 100, the arch frame grab 300 is connected to the driving mechanism 200, the arch frame grab 300 is used to clamp the arch frame 20, and the driving mechanism 200 is used to drive the arch frame grab 300 to pitch, swing or rotate; the support member 400 is detachably arranged on the arch frame grab 300, and the support member 400 is used to support and limit the multiple arch frames 20. In this embodiment, the arch frame 20 is clamped by the arch frame grab 300, and the arch frame grab 300 is driven to pitch, swing or rotate by the driving mechanism 200, which greatly improves the angle adjustment range of the arch frame 20 driven by the arch frame grab 300, so as to facilitate faster adjustment of the posture of the arch frame 20, thereby significantly improving the construction efficiency; not only that, the arch frame 20 is also supported by the support member 400, which can play a good supporting role in supporting the arch frame 20, so that the multiple arch frames 20 are more stable when erecting the arch, which is convenient for bolt assembly, and further improves the construction efficiency.

[0035] It can be understood that the driving mechanism 200 can drive the arch frame gripper 300 to complete pitching, swinging and rotating movements simultaneously, or can drive the arch frame gripper 300 to complete pitching, swinging or rotating movements successively, which is not specifically limited here.

[0036] Furthermore, the driving mechanism 200 includes a pitch driving member 210 , a rotation driving member 220 and a swing driving member 230 which are sequentially connected in transmission. The pitch driving member 210 is connected to the grab arm 100 , and the swing driving member 230 is connected to the arch grab 300 .

[0037] In this embodiment, since the grab arm 100, the pitch drive 210, the slewing drive 220, the swing drive 230 and the arch grab 300 are connected in sequence, the driving mechanism 200 drives the arch grab 300 to perform a pitch motion, which means that the driving mechanism 200 drives the arch grab 300 to perform a circular motion relative to the grab arm 100 in a vertical plane; the slewing drive 220 drives the arch grab 300 to perform a rotational motion, which means that the slewing drive 220 drives the arch grab 300 to perform a rotational motion relative to its installation plane; the swing drive 230 drives the arch grab 300 to perform a swing motion, which means that the swing drive 230 drives the arch grab 300 to perform a circular motion in a plane perpendicular to the rotation plane of the slewing drive 220. In this way, the multi-dimensional posture adjustment of the arch grab 300 is achieved through the pitch drive 210, the slewing drive 220 and the swing drive 230, so that the arch 20 can be quickly and accurately docked, thereby significantly improving the construction efficiency.

[0038] Optionally, the pitch drive component 210 and the swing drive component 230 may be drive cylinders, and the slew drive component 220 may be a slew reducer. Of course, it may also be other drive devices, as long as it can achieve the above functions, and no specific limitation is made here.

[0039] Furthermore, the driving mechanism 200 also includes a fixing member 240 , which is connected to the rotary driving member 220 . One end of the pitch driving member 210 is hinged to the grab arm 100 , and the other end is hinged to the fixing member 240 . The fixing member 240 is also hinged to the grab arm 100 .

[0040] In this embodiment, the rotary drive member 220 is installed on the fixed member 240. Since the fixed member 240 is hinged to the grab arm 100, one end of the pitch drive member 210 is hinged to the fixed member 240, and the other end is hinged to the grab arm 100. Therefore, the fixed member 240 can be driven to rotate relative to the grab arm 100 by extending and retracting the pitch drive member 210. Moreover, since the hinge points among the fixed member 240, the grab arm 100 and the pitch drive member 210 are on the vertical plane, the fixed member 240 can be driven to rotate relative to the vertical plane by the pitch drive member 210, thereby driving the rotary drive member 220, the swing drive member 230 and the arch gripper 300 to perform pitch movements.

[0041] Furthermore, the driving mechanism 200 also includes an adjusting seat 250, which is connected to the rotary driving member 220, and the arch frame gripper 300 is rotatably arranged on the adjusting seat 250, and one end of the swing driving member 230 is hinged to the adjusting seat 250, and the other end is hinged to the arch frame gripper 300.

[0042] In this embodiment, by connecting the adjustment seat 250 with the rotary drive member 220, the rotary drive member 220 can drive the adjustment seat 250 to rotate relative to the installation plane of the rotary drive member 220 itself, thereby driving the arch frame gripper 300 to rotate through the adjustment seat 250.

[0043] Since the arch frame gripper 300 is also hinged to the adjustment seat 250, one end of the swing drive member 230 is hinged to the adjustment seat 250, and the other end is hinged to the arch frame gripper 300, and the plane where the hinge point between the arch frame gripper 300, the swing drive member 230 and the adjustment seat 250 is located is perpendicular to the installation plane of the rotary drive member 220. Therefore, the extension and retraction of the swing drive member 230 can drive the arch frame gripper 300 to swing on a plane perpendicular to the installation plane of the rotary drive member 220.

[0044] Furthermore, the support member 400 includes a support rod 410 , and the support rod 410 is disposed on the arch gripper 300 .

[0045] In this embodiment, by arranging a support rod 410 on the arch frame gripper 300 and making the extension direction of the support rod 410 perpendicular to the direction perpendicular to the arch frame 20 clamped by the arch frame gripper 300, not only can the support rod 410 support the arch frame 20 clamped by the arch frame gripper 300 to prevent the arch frame 20 from shaking or even falling during movement, thereby improving stability, but the support rod 410 can also support multiple arch frames 20 at the same time, that is, it has a good stabilizing effect on the support of multiple arch frames 20, making the arch frame 20 more stable when erecting the arch, and facilitating bolt assembly, thereby improving construction efficiency.

[0046] Furthermore, the support member 400 further includes a sleeve 420 and a fastener 430 . The sleeve 420 is disposed on the arch gripper 300 . The support rod 410 is movably disposed in the sleeve 420 . The fastener 430 is disposed on the sleeve 420 and is used to fix the support rod 410 .

[0047] In this embodiment, the support rod 410 is set on the sleeve 420, so that the support rod 410 is limited to prevent it from falling off; and the support rod 410 is movable relative to the sleeve 420, so that the length of the support rod 410 can be adjusted according to different arch frame 20 spacings; after the length of the support rod 410 is determined, the sleeve 420 is passed through the fastener 430 and abutted against the support rod 410 to fix the support rod 410.

[0048] Moreover, the support rod 410 is a retractable structure, so that the length of the support rod 410 can be adjusted according to the spacing between different arch frames 20, thereby improving the adaptability of the arch frame clamping device.

[0049] It should be noted that the support rod 410 can be detachably mounted on the sleeve 420, so it is convenient to assemble or disassemble the support rod 410; when the support rod 410 is not needed, the support rod 410 only needs to be disassembled, and when the support rod 410 needs to be used, it only needs to be installed on the sleeve 420.

[0050] Furthermore, the number of the support rods 410 includes at least two, and at least two support rods 410 are both arranged at the left and right ends of the arch frame gripper 300 , and at least two support rods 410 are used together to support the arch frame 20 .

[0051] In this embodiment, in order to further improve the stability of the support rod 410 supporting the arch frame 20, multiple support rods 410 are provided to jointly support the arch frame 20, thereby increasing the contact area between the support rod 410 and the arch frame 20 to prevent the arch frame 20 from sliding or even falling off.

[0052] Optionally, the number of the support rods 410 is two, and it can be understood that the number of the sleeves 420 is also two, and the two sleeves 420 are symmetrically arranged at both ends of the arch gripper 300, so that the two support rods 410 are symmetrically arranged.

[0053] Furthermore, the arch frame gripper 300 includes a support platform 310, a clamping drive member 320 and at least two clamping jaws 330. The two clamping jaws 330 are rotatably arranged on the support platform 310. The two ends of the clamping drive member 320 are respectively hinged to the two clamping jaws 330 for driving the two clamping jaws 330 to clamp the arch frame 20.

[0054] In this embodiment, the clamping drive member 320 drives the clamping ends of the two clamping jaws 330 to move toward or away from each other, so that the two clamping jaws 330 can clamp or take and place the arch frame 20.

[0055] Optionally, two clamps 330 form a group, and multiple groups of clamps 330 can be set on the support platform 310, and the multiple groups of clamps 330 are arranged in sequence and spaced along the length direction of the support platform 310, so as to improve the stability of the clamps 330 clamping the arch frame 20.

[0056] It can be understood that the sleeve 420 is disposed at the end of the support platform 310 , and the support rod 410 extends in a direction perpendicular to the support platform 310 .

[0057] Furthermore, the arch frame gripper 300 also includes at least two limiting members 340 , and the at least two limiting members 340 are relatively arranged on two sides of the support platform 310 , and the at least two limiting members 340 are used to limit the arch frame 20 .

[0058] In this embodiment, by setting limit members 340 on both sides of the support platform 310, the clamped arch frame 20 is limited to prevent the arch frame 20 from sliding or even falling off, thereby further improving the stability of the arch frame gripper 300 clamping the arch frame 20.

[0059] Similarly, two limit members 340 form a group, and the limit member 340 clamp 330 can be set on the support platform 310, and multiple groups of limit members 340 are sequentially spaced along the length direction of the support platform 310, thereby improving the stability of the arch frame 20.

[0060] Furthermore, the arch clamping device also includes a fixing mechanism 500, which is arranged on both side walls of the supporting platform 310. The fixing mechanism 500 is used to fix the hanging basket, thereby facilitating construction operations.

[0061] In summary, the embodiment of the utility model provides an arch frame clamping device 10 and a tunnel engineering trolley, which clamps the arch frame 20 through the arch frame gripper 300, and drives the arch frame gripper 300 to pitch, swing or rotate through the driving mechanism 200, which greatly improves the angle adjustment range of the arch frame 20 driven by the arch frame gripper 300, thereby facilitating faster adjustment of the posture of the arch frame 20, thereby significantly improving the construction efficiency; not only that, the arch frame 20 is also supported by the support member 400, which can make multiple arch frames 20 more stable when erecting the arch, facilitate bolt assembly, and further improve construction efficiency.
