[0032] The pipeline gallery diaphragm fast linkage construction trolley of this embodiment is as follows Figure 1 , including: a steel bar tying trolley 1 and a concrete molding trolley 2 whose head end is connected to the tail end of the steel bar tying trolley 1.

The column 4 can be telescopic, and the column 4 is provided with a lifting cylinder 4, which can change the height of the steel bar binding trolley 1. The wing plate template 6 forms a four-bar linkage with the gantry 7 through two connecting rods, and is supported on the gantry 7 by an oblique screw rod; in this way, when demoulding, the screw rod is removed, and through the characteristics of the four-bar linkage, it can be demoulded in the horizontal and vertical directions at the same time, which is easier.

[0034] The first hydraulic system includes a first transverse movement cylinder 12, a first vertical fine-tuning cylinder 13 and a rotating cylinder 14; the binding platform is located on the top of the steel bar binding trolley and can be pushed by the first vertical fine-tuning cylinder 13 to move in the vertical direction relative to the steel bar binding trolley 1; the binding platform can be pushed by the first transverse movement cylinder 12 to move horizontally perpendicular to the steel bar binding trolley 1 relative to the steel bar binding trolley 1; both sides of the binding platform are provided with flippable movable plates 15; the rotating cylinder 14 can push the movable plates 15 to flip; the wing plate formwork 6 is supported by the gantry 7 of the steel bar binding trolley.

[0035] like Figures 7 to 10 The main structure of the concrete mold trolley 2 is the same as that of the steel bar binding trolley, both of which are gantry assemblies and drive systems; no further description is given. The concrete mold trolley 2 also includes an I-shaped plate template assembly 20 and a second hydraulic system;

[0036] The second hydraulic system includes a second transverse shift cylinder 21, a second vertical fine-tuning cylinder 22, a transverse cylinder 23 and a rotating cylinder; the I-beam formwork assembly is located on the top of the concrete molding trolley 1 and can be pushed by the second vertical fine-tuning cylinder 22 to move in the vertical direction relative to the concrete molding trolley; the I-beam formwork assembly can be pushed by the second transverse shift cylinder 21 to move horizontally perpendicular to the concrete molding trolley relative to the concrete molding trolley; the I-beam formwork assembly includes an upper cross board, a web formwork and a bottom formwork; the outer side of the upper cross formwork is provided with a telescopic adjustment plate 26; the transverse cylinder 23 can push the telescopic adjustment plate 26 to adjust the size of the upper cross formwork, and the rotating cylinder can push the web formwork to rotate; in this embodiment, in order to simplify the structure and save costs, one end of the transverse cylinder 23 is detachably installed, so that the function of the rotating cylinder can be realized by installing the detachable end on the mounting hole 25 of the web formwork.

[0037] The front end of the steel bar tying trolley 1 is provided with a concrete hanger 16; the hanger 16 is provided with a motor 18, which can lift the concrete cart 17 onto the steel bar tying trolley 1, and the top surfaces of the steel bar tying trolley 1 and the concrete molding trolley 2 are provided with a connecting track 19; the concrete cart 17 can move on the track 19.

[0038] The hydraulic motor, the first hydraulic system and the second hydraulic system can be controlled by a remote control handle.

[0039] The pipe gallery diaphragm construction method using the pipe gallery diaphragm quick linkage construction trolley as described above comprises the following steps:

[0040] (1) The steel bar tying trolley enters the first workstation, ties the steel bars of the wing plates on both sides of the first workstation's pipe gallery diaphragm, and then performs concrete pouring operations; the jacking cylinder, the first transverse cylinder, and the first vertical fine-tuning cylinder adjust the position and elevation of the tying platform for precise positioning; and during the wing plate pouring operation, the movable plate 15 is pushed to flip by the rotating cylinder 14, thereby making room on both sides so that the concrete truck can pour from top to bottom;

[0041] (2) During the curing of the concrete of the wing plates on both sides of the first-station corridor diaphragm, the steel bar tying trolley continues to carry out the steel bar tying operation of the I-shaped plate of the first-station corridor diaphragm;

[0042] (3) After the first station of the corridor diaphragm I-shaped plate reinforcement is tied, the technicians arrange the stress points on the corridor according to the simulated stress structure, use the lifting rope to lift the reinforcement frame of the I-shaped plate, and move the tying trolley forward to the next station to start tying the wing plate reinforcement on both sides of the corridor diaphragm; at the same time, the concrete casting trolley synchronously follows the first station and takes position; the reinforcement frame of the I-shaped plate is placed on the concrete casting trolley;

[0043] (4) Similarly, the concrete molding trolley can adjust the position and elevation through the jacking cylinder, the second lateral movement cylinder 21, and the second vertical fine-tuning cylinder 22 for precise positioning;

[0044] Since there will inevitably be errors in the pouring of the side walls of the pipe gallery, a telescopic adjustment plate 26 is designed on the outer side of the upper horizontal formwork in contact with the side wall, and is pushed by the horizontal oil cylinder 23 for adjustment to adapt to the error. In actual construction, since one end of the horizontal oil cylinder 23 is a movable and detachable structure, this end can be connected to the telescopic adjustment plate 26 to adjust according to the on-site environment;

[0045] Since the web template is vertical, it is very stable during layout. Therefore, after one end of the transverse oil cylinder 23 is connected to the web template, the web template can be tilted to the position, rotated to a vertical state, and then reinforced by a screw.

[0046] The concrete casting trolley performs the concrete pouring operation of the I-shaped slab of the corridor diaphragm at the first station. During the concrete curing period, the steel bar tying trolley performs the concrete pouring operation of the wing slabs on both sides of the corridor diaphragm at the next station, and then performs the steel bar tying operation of the I-shaped slab of the corridor diaphragm at the next station.

[0047] (5) After the reinforcement binding work of the I-shaped plate of the corridor diaphragm is completed at the next workstation, the stress points are arranged on the corridor, and the reinforcement skeleton of the I-shaped plate is lifted up using a lifting rope. The reinforcement binding trolley moves forward to the next workstation to bind the reinforcement of the wing plates on both sides of the corridor diaphragm; at the same time, the concrete casting trolley is synchronously followed and put into place at the next workstation;

[0048] (6) The concrete casting trolley performs the concrete pouring operation of the I-shaped slab of the pipe gallery diaphragm at the next station. During the concrete curing period, the steel bar tying trolley performs the concrete pouring operation of the wing slabs on both sides of the pipe gallery diaphragm at the next station, and then performs the steel bar tying operation of the I-shaped slab of the pipe gallery diaphragm at the next station;

[0049] (7) Repeat steps (5) and (6) in sequence until the construction is completed.

[0050] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementations. All technical solutions formed by equivalent replacement are within the protection scope required by the present invention.
