Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1-3, according to the embodiment of the present invention, the utility model provides a utility tunnel rectangular trolley, including an internal supporting structure 1, the top of the internal supporting structure 1 is connected with a cross beam 2 through a bolt, both sides of the internal supporting structure 1 are respectively connected with a column 4 through a hydraulic telescopic system 3, both ends of the cross beam 2 are respectively hinged with the top end of the column 4, the bottom of the internal supporting structure 1 is connected with a hydraulic lifting system 5 and a traveling system 6, the hydraulic lifting system 5 is located both sides of the traveling system 6; the top of crossbeam 2 is equipped with top template 7, the outside of stand 4 is equipped with side wall template 8. The two ends of the hydraulic telescopic system 3 are respectively movably connected with the two sides of the internal supporting structure 1 and the inner sides of the stand columns 4, the internal supporting structure 1 is square, and corner supports 9 are arranged in the internal supporting structure 1. The walking system 6 is walking wheels symmetrically distributed at the bottom of the internal supporting structure 1.
The construction method of the rectangular trolley for the comprehensive pipe rack comprises the following steps:
s1, paving the walking tracks, after the concrete of the bottom plate of the comprehensive pipe gallery is poured in advance and reaches the design strength, measuring, paying off and positioning the concrete surface, paving the walking tracks on the concrete of the bottom plate, wherein the walking tracks are smooth and straight and are firmly installed, and the distance is just matched with the trolley walking system, as shown in figure 1. The bottom of the two sides of the trolley is provided with 4 walking wheels which are symmetrically arranged below the bottom longitudinal beam of the single-section trolley. The diameter of the walking wheel is 300, and the walking track is a light rail of 38 kg/m.
S2, assembling a rectangular trolley of the comprehensive pipe gallery in the hole, wherein the internal supporting structure of the trolley adopts a 22a I-shaped steel square structure, two corner supports and one butt support are used in the middle of the trolley, and channel steel is longitudinally adopted for reinforcing connection. The template frame body is supported by 22a I-steel, consists of a cross beam and two upright posts and is connected by an oval hinge. The crossbeam directly adopts bolted connection with inside to support, uses hydraulic telescoping system to contact between stand and the inside bearing structure, and swing joint is adopted at hydraulic telescoping system both ends. After the trolley main truss is installed, debugging before use is carried out, wherein the debugging comprises walking, hydraulic pressure, a screw rod piece, inner side template folding and unfolding and top die lifting system overall debugging.
S3, positioning the rectangular trolley of the comprehensive pipe gallery, and moving the trolley to the designed position along the rail after the side wall and the top plate steel bars are bound. Adjusting a screw rod and a braking device at the bottom of the trolley, locking a walking wheel, painting template paint, starting a hydraulic lifting system (a hydraulic pump supporting system), lifting the whole trolley, and determining the elevation and the central position of the template by matching with measuring personnel. If the elevation and the center line position have deviation, the hydraulic system is used for local adjustment. The plug template adopts a 50mm thick wood pattern, and is matched with the distribution ribs to be fixed firmly. The control is mainly as follows: the trolley is lifted synchronously and symmetrically, and the positions of the top template and the side die are matched with the measurement and accurate positioning. Note that: the plug die is firmly reinforced to prevent the die from expanding due to overlarge pressure during concrete pouring.
