[0045] The steel bar binding platform is arranged on the left and right sides of the trolley frame 1, and the steel bar support frame is arranged on the trolley frame 1 along the circumference of the tunnel;

[0046] The steel bar binding platform includes a first binding platform 3 and a second binding platform 4; the first binding platform 3 is located on the inner side of the steel bar support frame, and the second binding platform 4 is located on the outer side of the steel bar support frame; the steel bar binding platform is telescopically arranged on the trolley frame 1 in the transverse direction;

[0048] The traveling mechanism 6 is arranged at the bottom of the trolley frame 1, and is used to drive the steel bar binding trolley to move along the axial direction of the tunnel;

[0049] The translation mechanism 5 and the traveling mechanism 6 alternately support the steel bar binding trolley under the lifting action of the first lifting mechanism 7.

[0050] In the specific embodiments of the present application, Figure 1 As shown, the steel bar binding trolley is an axially symmetrical structure as a whole. The trolley frame 1 is specifically an axially symmetrical portal frame structure. There are multiple steel bar binding platforms, and the multiple steel bar binding platforms are symmetrically distributed on the left and right sides of the trolley frame 1 along the horizontal direction of the tunnel. The steel bar binding platform includes a first binding platform 3, which is used for workers to bind steel bars on the inner side of the steel bar support frame; the steel bar binding platform also includes a second binding platform 4, which is used for workers to bind steel bars on the outer side of the steel bar support frame.

When the steel bar binding trolley moves to the working surface under the drive of the traveling mechanism, the translation mechanism 5 is first pushed downward by the first lifting mechanism 7, so that the translation mechanism 5 replaces the traveling mechanism 6 to support the steel bar binding trolley, and then the laser calibration device set in the middle of the trolley frame 1 is started, and the steel bar binding trolley is driven by the translation mechanism 5 to translate horizontally along the tunnel until the axis of the steel bar binding trolley coincides with the axis of the tunnel, and the translation mechanism 5 is continuously pushed downward by the first lifting mechanism 7, so that the upper steel bar support frame is lifted as a whole until it is lifted to the designed position of steel bar binding, and then the first binding platform 3 and the second binding platform 4 are extended to the outside of the trolley frame 1 to carry out the steel bar binding work.

[0052] The steel bar support frame includes a longitudinal steel bar support frame 16 and an annular steel bar support frame 15;

[0072] A second lifting mechanism 8 is also provided at the bottom of the trolley frame 1 for auxiliary support of the steel bar binding trolley;

[0073] The second lifting mechanism 8 is disposed at the bottom of the trolley frame 1 .

[0074] In the specific embodiments of the present application, Figure 2 As shown, the second lifting mechanism 8 is a jack. Multiple second lifting mechanisms 8 are symmetrically distributed on the left and right sides of the bottom of the trolley frame 1 along the tunnel transverse direction, and multiple second lifting mechanisms 8 on the same side are evenly and spacedly distributed between the traveling mechanisms 6 on the corresponding sides. When the translation mechanism 5 replaces the traveling mechanism 6 to support the steel bar binding trolley, the second lifting mechanism 8 is started to assist in supporting the steel bar binding trolley.
