[0021] like Figures 1 to 3 As shown, the utility model provides a small-section tunnel arch installation trolley, comprising:

[0022] The scraper 1 has a mechanical arm 2, and the end of the mechanical arm 2 is detachably connected to a mounting base 3;

[0023] A height adjustment block 5, whose length is adjustable, and the height adjustment block 5 is fixedly arranged on the top of the mounting seat 3;

[0024] A mechanical gripper 4, which is fixedly arranged on the height adjustment block 5 and is used to grab the arch frame;

[0025] The mounting frame 6 is an inverted U-shaped structure, and the mounting frame 6 is fixedly arranged at the bottom of the mounting seat 3, and the center of the mounting frame 6 is in the same straight line as the center of the mounting seat 3; foldable hanging baskets are respectively installed on both sides of the mounting frame 6.

[0026] In this technical solution, a small mechanical scraper 1 is used as the bearing body of the small-section tunnel arch installation trolley to facilitate entry into the tunnel. The scraper 1 can be a commercially available small scraper, which has a multi-degree-of-freedom mechanical arm 2 that can achieve precise adjustment of the arch position, and the grab at the end of its mechanical arm 2 is replaced by the mounting seat 3. The height adjustment block 5 is used to flexibly adjust the height of the arch according to the height of the tunnel. After the mechanical gripper 4 grabs and fixes the arch, the arch is accurately adjusted to the designed position by the mechanical arm 2, and then fixed and installed manually. For the convenience of manual operation, two folding hanging baskets are installed at the bottom of the mounting seat 3 through the mounting frame 6, so that manual operation can be performed on both sides of the tunnel. And considering the convenience of entering and exiting the small-section tunnel, a folding hanging basket is used, and the folding hanging basket is opened after entering the tunnel and reaching the arch installation position.

[0027] In another technical solution, the height adjustment block 5 includes one or more stacked standard sections, and two adjacent standard sections are fixedly connected. A suitable number of standard sections are selected according to the height of the roadway, and the standard sections can be conventional steel sections to save costs.

[0028] In another technical solution, the mechanical gripper 4 includes a base 41, a clamping cylinder 42, two transmission arms 43 and two clamping arms 44. The base 41 is fixedly arranged on the height adjustment block 5, and the clamping cylinder 42 is fixedly installed in the base 41. One end of the two transmission arms 43 is hinged to the movable end of the clamping cylinder 42, and the other end is respectively hinged to one of the clamping arms 44. The two clamping arms 44 are hinged together at one end close to the transmission arm 43. When in use, the two clamping arms 44 can be hinged together through a circular shaft 45, and support plates 46 are provided at both ends of the circular shaft 45. The support plates 46 are fixedly connected to the base 41 so that the two clamping arms 44 are always kept at the same height position. One end of the two transmission arms 43 is hinged to the movable end of the clamping cylinder 42, and the other end is hinged to a corresponding clamping arm 44, so that the two transmission arms 43 are set at an angle, and the opening faces the two clamping arms 44; one end of the two clamping arms 44 clamping the arch is the clamping end, and the other end is hinged together through the circular shaft 45 and hinged to the two transmission arms 43 respectively. When the clamping cylinder 42 is extended, the angle between the two transmission arms 43 will be increased, and then the clamping ends of the two clamping arms 44 will move away from each other; after the arch is placed, the clamping cylinder 42 is retracted, the angle between the two transmission arms 43 is reduced, and the clamping ends of the two clamping arms 44 are driven to move towards each other to clamp and fix the arch. When in use, one or more mechanical grippers 4 can be set on the height adjustment block 5 according to the size of the arch.

[0029] In another technical solution, the foldable hanging basket includes: a base frame, which is formed by hingedly connecting two base frame plates 10; pillars are hingedly connected to the four corners of the base frame; one of the pillars is connected to the side wall of the mounting frame 6; two folding rods 9 and fixed rods 7 are arranged on both sides of the base frame, one end of the two folding rods 9 is hinged to the hinge of the two base frame plates 10, and the other end is hinged to the upper end of the pillar 11 of the base frame near the scraper 1; one end of the fixed rod 7 is detachably connected to the pillar of the base frame away from the scraper 1, and the other end is detachably connected to the two folding rods 9. The foldable hanging basket is arranged in front of the scraper 1, and according to the travel direction of the scraper 1, the end close to the scraper is the rear end, and the end away from the scraper 1 is the front end. Figure 1The figure shows the state of the foldable hanging basket when it is unfolded. The two-folding pull rod 9 is straightened to make the base frame perpendicular to the column 11 on the rear side, and then the fixing rod 7 is installed to make the column 8 on the front side perpendicular to the base frame, so that the foldable hanging basket is unfolded. It should be noted that a cross brace is fixedly provided between the two columns 8 on the front side and between the two columns 11 on the rear side to maintain the stability between the two. When the hanging basket needs to be folded, the fixing rods 7 on both sides are first removed, and then the two-folding pull rod 9 is folded, and the two base frame plates 10 are driven to overlap relative to each other, so that the column 8 on the front side is close to the column 11 on the rear side. When the distance between the column 8 on the front side and the column 11 on the rear side reaches the minimum, the two are temporarily fixed by a rope segment or a cable tie to complete the folding of the hanging basket.

[0030] In another technical solution, a rotary cylinder 12 is provided on both side arms of the mounting frame 6, and a mounting block 13 is fixedly provided on the column connecting the foldable hanging basket and the mounting frame 6, and the mounting block 13 is fixedly connected to the rotating shaft of the rotary cylinder 12. The foldable hanging basket is driven to rotate by the rotary cylinder 12. When the foldable hanging basket is in a folded state, the two foldable hanging baskets are rotated 90 degrees toward each other to be perpendicular to the mounting frame 6, thereby reducing the lateral size of the small-section tunnel arch frame installation trolley to better adapt to the movement in the small-section tunnel. After reaching the arch frame installation position, the two foldable hanging baskets are rotated 90 degrees in the opposite direction to be perpendicular to the mounting frame 6 and in the same vertical plane as an artificial construction platform. In order to ensure the stability of the foldable hanging basket, multiple rotary cylinders 12 can be provided on the two side walls of the mounting frame 6. Preferably, in order to further improve the stability of the hanging basket when in use, after the two folding hanging baskets are rotated in opposite directions to be in the same vertical plane as the mounting frame 6, one or more stiffening rods are installed on the back sides of the folding hanging basket and the mounting frame, and the two folding hanging baskets are connected to the mounting frame as a whole through the stiffening rods, and the stiffening rods are detachably connected to the three respectively.
