Embodiment 1

[0053] A multifunctional trolley, see details Figure 1-2 ( figure 2 The upper and lower two-way arrows in the middle represent the horizontal movement direction of the rebar feeding system, and the arc arrows represent the turning direction of the rebar accommodating arch), including the gantry system 1, the rebar feeding system 2, the working platform assembly 3, the rebar support Lifting device 4 and rotating telescopic arm assembly 5, the details are as follows:

[0054] The gantry system 1 includes a gantry frame 1.1 and a traveling mechanism 1.2 arranged on the gantry frame and used to drive the entire trolley to move. The gantry frame 1.1 includes a gantry column 1.11 (shown here). Four gantry uprights), gantry longitudinal beam 1.12 and upper frame 1.13, the specific structure can be designed based on the structure of the existing lining trolley. The walking mechanism 1.2 includes a walking part 1.21 for driving the trolley to walk and a traverse part 1.22 for drivi...

Embodiment 2

[0071] The difference from Example 1 is that:

[0072] The rotating connector 2.21 includes a balance beam D3, a tie rod D4, a pulley D5 and a wire rope D6, see details for details Image 6 , the balance beam is arranged horizontally and the length direction of the balance beam is the same as the turning direction of the arch frame, the moving part is arranged on the balance beam; the end of the single piece of the arch frame is hinged on the balance beam The two ends of the tie rod are respectively connected with the end of the single piece of the arch frame and the balance beam; the pulley is fixed on the upper door frame 1.13 of the trolley through the pulley support seat D7, and the pulley is used for Play a guiding role for the wire rope; one end of the wire rope is connected to the power source, and the other end is detachably connected to the dome position of the single piece of the arch connect).

[0073] The said steel bar anti-falling single piece includes the ear ...

Abstract

The invention provides a multi-function trolley. The multi-function trolley comprises a door frame system, a rebar feeding system and a work platform assembly. The rebar feeding system comprises a rebar containing arch frame, a rotating member, a horizontally-moving member and a rebar falling-proof assembly, the rebar containing arch frame comprises a group of arch frame single piece or at least two groups of arch frame single pieces arranged in parallel; and the rotating member comprises at least one group of rotating single piece, and each rotating single piece comprises a power source and arotating connecting piece. The horizontally-moving member comprises a driving source and horizontally-moving single pieces arranged with the rotating single pieces in a one-to-one correspondence mode. The rebar falling-proof assembly comprises at least one group of rebar falling-proof single piece arranged correspondingly with the arch frame single pieces. The work platform assembly comprises a top platform and a side direction platform group. The multi-function trolley can realize quick feeding of circumferential rebar. The invention further discloses a construction method for the multi-function trolley. The construction method comprises the following steps of circumferential rebar construction, longitudinal rebar construction and waterproof material construction, one machine with multiple purposes is realized, and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular, to a multifunctional trolley and a construction method thereof. Background technique [0002] Lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. The concrete lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process. It is used for the concrete lining construction of the inner wall of the tunnel. Before each concrete lining, it is necessary to complete the laying of the waterproof layer material and the binding of the steel mesh at the inner position of the concrete. [0003] At present, the laying of waterproof materials and the binding of steel bars in China are mostly simple benches, and the loading of steel bars is done manually. As the main reinforcem...
