[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 As shown, a slewing support 2 is provided on the chassis 1.1 of the traveling mechanism 1. The slewing support 2 rotates via a slewing drive mounted on the chassis 1. A control device 9 is fixedly mounted on the chassis 1 to the side of the slewing support 2. A telescopic arm 3 is hinged above the slewing support 2. The arm 3 extends, retracts, and changes its angle via a hydraulic device mounted on the chassis 1. A horizontal support 4 is fixedly connected to the other end of the arm 3. Figure 2 It can be seen that the fixed base 4.2 on the horizontal support 4 is fixedly connected to the extension arm 3, and the middle platform 5 is fixedly installed directly above the horizontal support 4. Figure 1 , Figure 2 and Figure 4 It can be seen that the middle platform 5 is fixed directly above the horizontal plate 4.3;

[0029] Combination Figure 1 , Figure 2 and Figure 3 As shown, hydraulic turntables 6 are fixedly mounted on both longitudinal rods 4.1 of the horizontal support 4, with the longitudinal rods 4.1 passing through the center of the hydraulic steering gear body 6.1; combined with Figure 2 , Figure 3 and Figure 5 It can be seen that the rotary fixed platform 7 is connected to the hydraulic turntable 6 through the fixed plate 6.2, and many round holes can be seen in area A on the rotary fixed platform 7. These round holes correspond to the round holes on the fixed plate 6 and are fixedly connected by screws.

[0030] like Figure 1 As shown, a telescopic ladder 8 is fixedly connected to the end of the rotating fixed platform 7, as follows. Figure 6 As shown, the upper end of the main body 8.1 of the telescopic staircase 8 is fixedly connected to the rotating fixed platform 7. A sliding rod 12 is horizontally installed on one side of the upper part of the main body 8.1. The upper end of the staircase guardrail 8.2 is slidably connected to the sliding rod 12 via a slider.

[0031] The middle part of the stair railing 8.2 is slidably connected to the horizontally mounted slide plate 13 on the stair body 8.1 via a slider. The slide plate 13 is fixed to the stair body 8.1, and the other end of the slide plate 13 is fixedly connected to the rotating platform 7 via a stabilizing device 8.3. The stabilizing device 8.3 is a rectangular frame structure.

[0032] A sliding plate 13 is fixedly installed at the lower end of the main body of the staircase 8.1. Similarly, the lower end of the staircase guardrail 8.2 is also slidably connected to the main body of the staircase 8.1, so that the staircase guardrail 8.2 can slide relative to the main body of the staircase 8.1.

[0033] like Figure 1 As shown, guardrails 11 are installed on the upper surface of the rotating fixed platform 7 via multiple telescopic rods 10.

[0034] The slewing bearing 2, the boom 3, and the hydraulic turntable 6 are all connected to the control device 9 via electrical wires.

[0035] When in use, start the walking mechanism 1 to reach the tunnel construction position, and then control the slewing support 2 through the control device 9 to rotate the slewing support 2 so that the boom 3 faces the tunnel construction point. Then start the hydraulic device to change the angle between the boom 3 and the chassis 1.1 so that the end of the boom 3 faces the tunnel construction point. Then extend the boom 3 so that the construction platform at the end of the boom 3 can be located near the tunnel construction point.

[0036] When the boom 3 is extended, if the tunnel construction point is located at the middle platform 5, the operator can directly place the operator on the middle platform 5 to carry out the construction.

[0037] If the tunnel construction site is to the side of the central platform 5, the hydraulic turntable 6 in the direction of the tunnel construction site is activated by the control device 9, so that the rotating fixed platform 7 rotates around the longitudinal bar 4.1 until it rotates to the direction of the tunnel construction point. If the operator can reach the construction point, the guardrail 11 is pulled up by the telescopic bar 10. The operator stands inside the guardrail 11 of the rotating fixed platform 7 to operate, which greatly improves safety.

[0038] If the tunnel construction site is found to be large, operators can also work from the telescopic ladder 8. When using the telescopic ladder 8, the operator can pull or push the ladder guardrail 8.2. Since the ladder guardrail 8.2 is slidably connected to the ladder body 8.1, the ladder guardrail 8.2 can be located away from or close to the ladder body 8.1. This can better protect the construction personnel and facilitate their access to the ladder body 8.1, thus speeding up the construction progress. At the same time, since the middle and lower parts of the ladder body 8.1 are slidably connected to the ladder guardrail 8.2 via the sliding plate 13, this can effectively prevent operators from accidentally falling from the telescopic ladder 8 and causing danger.

[0039] This application provides a bracket on the chassis 1.1 for placing the boom 3, so that the boom 3 can be placed on the bracket when not in use, thereby extending the service life of the boom 3.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
