Problems solved by technology

[0010]The main disadvantages of the front fulcrum hanging basket are: due to the different cable angles of different sections, the cable force is also actively and passively adjusted during the pouring process of the same section, and the entire hanging basket The force system of the basket is more complicated
[0013]The existing hanging basket technology generally adopts a simple method of on-the-spot measurement and recording by technicians to deal with this. The disadvantage is that it must rely on personnel, and sometimes it is difficult to measure during construction , and this method cannot automatically feed back the information to the quality and safety department, which is not conducive to timely discovery and handling of problems

Embodiment Construction

[0024] Such as figure 1 As shown, the present invention is respectively provided with strain gauges on the front tie beam 1 of the hanging basket, the shearing device 2, the front end 3 of the inner walking beam, the front end 4 of the outer walking beam, and the extension rod 5 of the cable, and these strain gauges pass through the signal line Connected with the electric control cabinet, the electric control cabinet adopts a single-chip microcomputer or PLC, and is equipped with a preset program and an alarm device to detect the signal of each sensor and compare the deformation with the set value. When the deformation exceeds the set value, , the alarm device activates the alarm. The present invention adopts the above-mentioned technical scheme to monitor the stress and deformation of the hanging basket structure in time, prevent the occurrence of malignant accidents, and ensure the construction quality and construction safety.

Abstract

The invention discloses a cradle stress and deformation early warning system. The early warning system is characterized in that: the early warning system comprises sensors mounted on all the parts and a control cabinet, the sensors are electrically connected with the control cabinet, the control cabinet is provided with a preset program and a warning device, the stress value and the deformation value of each controlled part transmitted by the sensors are compared with preset values, and when the stress value or the deformation value exceeds the preset value, the warning device is started to give the alarm. The adopted technical scheme can timely monitor the stress and deformation of a cradle structure in order to prevent the occurrence of severe accidents and ensure the construction quality.

Description

technical field [0001] The invention belongs to the field of construction machinery and tools, and relates to a hanging basket for bridge construction, in particular to an early warning system capable of timely monitoring the stress and deformation of important structural parts of the hanging basket during the construction process. Background technique [0002] The hanging basket is the main machine tool for bridge cantilever pouring, and it is a movable construction platform that walks along the track. [0003] Hanging baskets are mainly divided into rear fulcrum hanging baskets and front fulcrum hanging baskets from the structural stress characteristics. [0004] The rear fulcrum hanging basket can be applied to various cantilever cast bridges, including continuous rigid frame, continuous beam, cable-stayed bridge, etc. The main stress system of the hanging basket at the rear fulcrum is a cantilever beam. The second half of the cantilever beam is anchored on the poured co...
