Reversible suspended basket wheel type travelling system and method

Abstract

The invention discloses a reversible suspended basket wheel type travelling system and a reversible suspended basket wheel type travelling method. The system comprises two front travelling devices consisting of forward pressure wheels, two rear travelling devices consisting of back pressure wheels, two joist steel rails and a travelling power device consisting of a drive motor. The method comprises the following steps of: adjusting the position of a rotation limit plate, and setting the position of an automatic control switch contact I on an intersection angle regulation and control plate; starting the drive motor to ensure that a suspended basket slowly advances along the joist steel rails; stopping the advance of the suspended basket and transmitting a flashing light prompt or an alarm bell prompt by using a travelling limit prompt lamp / bell once the automatic control switch contact I is contacted with an automatic control switch contact II on the rotation limit plate; switching offa power supply, applying a rear anchor constraint of the suspended basket, and setting a front supporting point cushion block; starting construction operation after the suspended basket is positioned; and detaching the rear anchor constraint and the front supporting point cushion block after the construction is finished. The system has a high automation degree and high coordination performance, is labor-saving during travelling and is convenient, high-efficient and stable; and by the system and the method, the construction problem of the travelling of the suspended basket along a curve rail, particularly a small curve radius rail is solved.

Description

technical field [0001] The invention belongs to the technical field of hanging basket construction, and in particular relates to a wheeled walking system and method for a variable direction hanging basket. Background technique [0002] The cantilever pouring method is a commonly used construction method in the construction of continuous girder bridges. In the construction, the hanging basket is used as the mobile formwork, and the pouring of concrete, binding of steel bars, and tensioning of prestressed tendons are all carried out in the hanging basket. At present, the hanging basket used in the cantilever pouring construction of the bridge, when it moves to the next section in the unloaded state, the running is basically realized by sliding horizontally on the track, and the sliding device is mostly installed between the track and the longitudinal beam of the hanging basket The slider is generally a PTFE plate. In order to limit the derailment of the hanging basket during t...

AI Technical Summary

Problems solved by technology

However, for the construction of hanging baskets on curved bridges, especially bridges with small curve radius, since the sliding track is a flat curve with a small radius, it is difficult to control the running direction of the hanging basket. Conducive to the safe use of hanging basket structure

In addition, slow walking speed affects construction efficiency
