After the tunneling machine completes the excavation, single pneumatic anchor drilling machines and air drills are manually operated to construct top anchors and anchor cables.

[0003] The existing temporary support has the following shortcomings:

[0004] (1) Poor adaptability of airborne temporary support: When the tunnel is short, the top frame of the temporary support at the rear will hit the top first, affecting the normal cutting operation of the cutting head of the tunnel boring machine.

[0030] like Figure 1-Figure 4 As shown, a movable airborne temporary support according to an embodiment of the present application includes a temporary support body 103 , the temporary support body 103 is installed on a mobile device 104 , and the mobile device 104 is installed on a cutting portion 101 .

[0031] The moving device 104 includes a movable airborne temporary support, and the moving device 104 can control the longitudinal movement position of the temporary support body 103 .

[0032] The moving device 104 includes a sliding platform 01 , which is fixedly connected to the temporary support body 103 , and the sliding platform 01 realizes the sliding of the temporary support body 103 by longitudinal movement.

[0033] The moving device 104 also includes a sliding cylinder 02 , an oil pipe connecting block 03 and an oil pipe transition block 04 . The sliding cylinder 02 is installed on the cutting part 101 , and the output end of the sliding cylinder 02 is fixedly connected to the oil pipe connecting block 03 and the oil pipe transition block 04 .

[0034] The sliding platform 01 is slidably connected to the fixed base 07 .

[0035] The fixed base 07 has a fixed limiting structure to prevent shearing of the fastening bolts.

[0036] The temporary support body 103 is installed above the mobile device 104 and is fixedly connected to the sliding platform 01. The sliding of the airborne temporary support body 103 is achieved by the longitudinal movement of the sliding platform 01 in the mobile device 104. The sliding platform 01 in the mobile device 104 is slidingly connected to the fixed base 07. The sliding of the sliding platform 01 is achieved by the sliding cylinder 02, that is, the fixed base 07 in the mobile device 104 is connected to the fork frame 1104 in the cutting part 101 by bolts and positioning blocks and is fixed thereto. The cylinder body of the sliding cylinder 02 is also fixedly connected to the fork frame 1104. The piston rod of the sliding cylinder 02 is fixedly connected to the sliding platform 01. The movement of the sliding platform 01 is controlled by the extension and retraction of the piston rod of the sliding cylinder 02, thereby achieving the sliding of the airborne temporary support body 103.

[0037] The output end of the sliding oil cylinder 02 is fixedly connected to the oil pipe connecting block 03 and the oil pipe transition block 04. The output end of the sliding oil cylinder 02 is extended to drive the temporary support of the sliding platform 01 and the movement of the operating platform 06.

[0038] The fluid supply for each action of the onboard temporary support is centralized through the oil pipe connection block 03 to the oil pipe transition block 04, which effectively avoids the multiple and disorderly failure points caused by the complexity of the pipelines. The oil supply connection is achieved between the oil pipe connection block 03 and the oil pipe transition block 04 through a high-pressure rubber hose, which is used to realize continuous fluid supply when the sliding platform 01 moves forward and backward.

[0039] The moving device 104 can control the longitudinal movement position of the airborne temporary support body 103, and can adjust the position of the airborne temporary support according to actual needs to ensure that the temporary support body 103 is positioned at the rear when the cutting head 1101 is cutting, and is positioned at the front during anchoring operations, thereby ensuring the normal cutting construction of the tunnel boring machine cutting head 1101 and improving the safety of the support operation.

[0040] A rotary reducer 05 is fixedly installed on the sliding platform 01 , and an output end of the rotary reducer 05 is fixedly connected to an operating platform 06 .

[0041] The operating platform 06 realizes operation positioning at any position within a range of 180 degrees by rotating the output end of the rotary reducer 05, which is convenient for personnel to step on. The operating platform 06 is rotated to the top of the cutting part 101 to realize the protection of the cutting head 1101 during the anchoring operation. The operating platform 06 can also be used to realize the climbing operation of personnel during anchoring. The operating platform 06 itself is designed with a stepping mechanism similar to a staircase, which can ensure stable stepping on a slope. The height of the operating platform 06 is determined by adjusting the position where the cutting part 101 stops before the equipment is shut down to ensure the convenience of the subsequent support operation, that is, the position of the cutting part 101 is docked according to the position and height required for support, so as to determine the position of the operating platform 06. Personnel step on the operating platform 06, and the operating platform 06 is provided with an anti-skid device made of an crocodile-mouth anti-skid plate to maintain stability. If necessary, a plug-in guardrail device can be added to increase the safety performance. Coupled with the stepping mechanism of the operating platform 06 itself, it can realize personnel stepping and climbing operations in any state.

[0042] The cutting part 101 includes a cutting head 1101, a cutting arm 1102, a cutting reducer 1103 and a fork frame 1104. The output end of the cutting reducer 1103 is fixedly connected to the cutting arm 1102. The cutting head 1101 is installed on the cutting arm 1102. The cutting reducer 1103 is fixedly installed on the fork frame 1104. The fixed base 07 and the sliding cylinder 02 are both fixedly installed on the fork frame 1104.

[0043] In summary, the working principle of a movable airborne temporary support and its moving device 104 according to an embodiment of the present invention is as follows:

[0044] The temporary support body 103 is installed above the mobile device 104 and is fixedly connected to the sliding platform 01. The sliding of the airborne temporary support body 103 is achieved by the longitudinal movement of the sliding platform 01 in the mobile device 104. The sliding platform 01 in the mobile device 104 is slidably connected to the fixed base 07. The sliding of the sliding platform 01 is achieved by the sliding cylinder 02, thereby achieving the sliding of the airborne temporary support body 103. The position of the temporary support body 103 is close to the cutting head 1101 when cutting through the mobile device 104. After that, the temporary support body 103 is positioned forward during the anchoring operation, thereby ensuring the normal cutting construction of the cutting head 1101 of the tunnel boring machine and improving the safety of the support operation. By setting the operating platform 06, the operating platform 06 can realize the operation positioning at any position within the range of 180 degrees through the rotation of the output end of the rotary reducer 05, which is convenient for personnel to step on. The operating platform 06 is rotated to the top of the cutting part 101 to realize the protection of the cutting head 1101 during the anchoring operation. The operating platform 06 can also be used to realize the climbing operation of personnel during anchoring.
