Further, the upper surface of the sliding seat 622 is inclined to better adapt to the shape of the reinforcing cage 3 and better support the reinforcing cage 3; a longitudinal movement driving cylinder 626 is arranged on the support frame 621, the longitudinal movement driving cylinder 626 is connected with one of the sliding seats 622, and the two sliding seats 622 are connected through a connecting plate 6221, so that the two sliding seats 622 are driven to synchronously slide along the support frame 621 through the longitudinal movement driving cylinder 626, and then the overall longitudinal position of the reinforcing cage 3 is adjusted when the longitudinal movement driving cylinders 626 of the two reinforcing cage grabbing and positioning mechanisms 62 act synchronously, and the deflection angle of the reinforcing cage 3 is adjusted when the longitudinal movement driving cylinders 626 of the two reinforcing cage grabbing and positioning mechanisms 62 act asynchronously; a lifting driving cylinder 627 is arranged inside the base housing 61, the support frame 621 is installed on the top of the lifting driving cylinder 627 through a hinged support 628, the lifting of the support frame 621 is controlled through the lifting driving cylinder 627, and then the overall radial movement position of the reinforcing cage 3 is adjusted when the lifting driving cylinders 627 of the two reinforcing cage grabbing and positioning mechanisms 62 act synchronously (since the tunnel reinforcing cage installation trolley is running on an arc-shaped track, the lifting here refers to adjusting along the radial direction of the tunnel), and the overturning angle of the reinforcing cage 3 is adjusted when the lifting driving cylinders 627 of the two reinforcing cage grabbing and positioning mechanisms 62 act asynchronously; the hinge shaft of the hinged support 628 is arranged perpendicularly to the longitudinal support frame 621, so that the support frame 621 has the freedom to rotate around the hinge shaft, which can be called the pitch freedom, a pitch driving cylinder 629 is arranged between the hinged support 628 and the support frame 621 to adjust the pitch angle of the support frame 621, that is, to adjust the pitch angle of the reinforcing cage 3. In summary, through the longitudinal movement, deflection, radial movement, overturning and pitch mentioned above and the circumferential movement of the tunnel reinforcing cage installation trolley 6 along the arc-shaped track 12, the six-degree-of-freedom adjustment of the reinforcing cage 3 is realized.

[0021] Further, the wheel set comprises driven wheel set 63 and driving wheel set 64, the driven wheel set 63 is arranged on the two side walls of the base shell 61, two sets of driven wheels are arranged on each side wall, each set of driven wheels comprises two driven wheels arranged staggered up and down, the two driven wheels are respectively located on the upper side and the lower side of the flange of the arc-shaped track 12, so that the base shell 61 is stably installed on the arc-shaped track 12 and cannot be separated from the arc-shaped track 12; the driving wheel set 64 is arranged inside the base shell and is connected with the driving motor 65 inside the base shell, the driving wheel set 64 is engaged with the teeth on the upper surface of the arc-shaped track 12, thereby realizing the driving of the tunnel reinforcement cage installation trolley 6 to walk on the arc-shaped track 12. Further, the clamping type parking device 66 is also arranged on the side wall of the base shell 61, when the reinforcement cage installation trolley 6 stops at a certain position, the clamping type parking device 66 clamps the flange of the arc-shaped track 12, so that the reinforcement cage installation trolley 6 is stably parked. Alternatively, in the case that there is no clamping type parking device 66, the driving motor 65 with good braking function can also be selected, and the reinforcement cage installation trolley 6 can also be stably stopped at the required position on the arc-shaped track 12.

[0022] During construction, the reinforcement cage 3 to be installed is placed on the sliding seat 622 of the reinforcement cage grabbing and positioning mechanism 62 of the tunnel reinforcement cage installation trolley, then the grabbing driving cylinder 625 drives the grabbing hook 623 to act, so that the reinforcement cage 3 is stably fixed on the sliding seat 622; then the tunnel reinforcement cage installation trolley carries the reinforcement cage 3 to walk along the arc-shaped track on the trolley to the designated position (i.e. preliminary positioning); then the tunnel reinforcement cage installation trolley 6 adjusts the six degrees of freedom of the reinforcement cage, i.e. longitudinal movement, deflection, radial movement, overturning, pitching and circumferential movement (i.e. fine positioning), so that the reinforcement cage 3 is accurately installed to the target installation position on the tunnel top surface (after fine positioning, the reinforcement cage is fixed on the tunnel top surface by manual operation).

[0023] For ease of description, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to describe one element or feature's relationship to another element or feature as illustrated in the drawings. It should be understood that the spatial terms are intended to encompass different orientations of the device in use or operation, except where the context explicitly dictates otherwise. For example, if the device in the drawings is turned over, an element described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0024] Moreover, relational terms such as "first" and "second", and the like can be used solely to distinguish one entity or action from another, without necessarily requiring or implying any actual relationship or order between such entities or actions.

[0025] It should be noted that the above-mentioned embodiments illustrate rather than limit the application, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the application. Accordingly, the legal scope of the application is defined only by the appended claims.
