Problems solved by technology

This kind of reverse buckle wheel method must have a track. This kind of track is very heavy. Only when the hanging basket is jacked up can the heavy walkway be inserted under the longitudinal beam of the hanging basket, the labor intensity is high, the speed is low, and there are unsafe factors

Embodiment Construction

[0015] The roller presser for hanging basketball is composed of anchor rod 1, nut 2, spherical support 3, pin shaft 4, balance frame 5, roller frame 6, roller 7, connector 8, embedded anchor rod 9 and chute 10, and the roller 7 is installed on the roller frame 6, the roller frame 6 is connected with the balance frame 5 with the pivot pin 4, the anchor rod 1 passes through the through hole on the balance frame 5 and the spherical support 3, and is connected with the embedded anchor rod 9 with the connector 8, The upper end of the anchor rod 1 is fixed on the balance frame 5 with a nut 2 and a spherical bearing 3. When the hanging basket is walking, the roller 7 rolls in the chute 10 but does not move, and the chute 10 slides on the pad 11 together with the hanging basket.

[0016] Roller frame 6 is two independent plates, adopts static fit method to be installed with two roller axles on every plate, and the other end of every roller axle is installed roller 7 with bearing. The ...

Abstract

The invention relates to a suspended basket spherical pressing wheel device for bridge cantilever pouring, comprising a plurality of anchor rods, a screw nut, a spherical support, a shaft pin, a balance frame, a roller frame, a roller, a connector, a bridge deck pre-cast anchor rod and a chute, wherein the roller is arranged on the roller frame connected with the balance frame via the shaft pin; and the anchor rods penetrate the roller frame and through holes on the spherical support to connect with the bridge deck pre-cast anchor rod via the connector. When the suspended basket runs, the pressing wheel device welded in the chute of the suspended basket rolls but does not move. By the suspended basket pressing wheel device, the suspended basket cantilever can run without running tracks and balance weights, thus enabling the suspended basket to have lighter self weight, lower cost, convenient operation and high efficiency. The cantilever running right-handed pressing wheel device has convenient assembly and disassembly without hand haulage in position conversion, and can be pushed for rolling on the suspended basket longitudinal beam. The suspended basket spherical pressing wheel device can ensure axial stress of the anchor rods and the bridge deck pre-cast anchor rod.

Description

technical field [0001] The invention relates to a bridge cantilever casting hanging basket. Especially the cantilever walking system without balance ballast hanging basket. Background technique [0002] The prestressed concrete rigid frame or continuous girder bridge is constructed by cantilever cast-in-place section by section, and each section is connected by steel bars and prestressed steel hinge lines. Cantilever concrete pouring and prestressing works are carried out on hanging baskets. After a segment is completed, the hanging basket needs to be cantilevered to move to the next position to continue construction, and so on until the last segment. [0003] Most of the cantilever casting hanging baskets currently use hanging baskets without balance weight, especially in the case of large bridge spans and large wind loads, only hanging baskets without balance weight can be used for cantilever construction. After the hanging basket has finished pouring a beam section, it...
