Embodiment Construction

[0024] The embodiments are further described below in conjunction with the accompanying drawings.

[0025] Referring to Fig. 1, Fig. 2, Fig. 3, 1-flexible support trolley, 2-rigid support trolley. As shown in the figure, there is one flexible support trolley and two rigid support trolleys, which are installed side by side and placed on four rails on both sides of the beam making yard. The dotted line frame in the figure shows the overall shape of the box girder. The main structure of the invention includes two rigidly supported trolleys, one softly supported trolley, a speed measuring device, a force measuring device, an alarm device, a hydraulic control part and an electrical control part. The flexible support trolley is composed of 4 active bicycles and 4 passive bicycles, which are hinged together with small balance beams, solid beams and outer frame beams. The rigid support trolley is composed of 2 active bicycles and 2 passive bicycles hinged together by a balance beam. ...

Abstract

The invention discloses a construction technique, that the motion of prefabricated beam on the base and the track, which can be used in box-beam moving vehicle of passenger transport special railway line. It is characterized in that: it comprises a flexible support vehicle, and two steel support vehicles, which are independently arranged on four tracks at two sides of beam producing field; and it also comprises a speed detector, a force detector, an alarm device, a hydraulic controller and an electric appliance controller. Wherein, the flexible support vehicle is formed by four driving single vehicles, four driven single vehicles, a hydraulic mechanical lock, a hydraulic support, a solid beam axle, a solid beam and a outer frame beam; the rigid support vehicle is formed by two driving single vehicles, two driven single vehicles, a small balance beam, a speed sensor, and a hydraulic support; the power transmission is completed by the transmission device of motor speed reducer via gear wheel to drive wheels; the walking of driven single vehicle is transmitted via small balance beam; the speed detector detects the synchronous property of walking; the force detector detects if the force is over the preset value; the whole support capacity can reach 900t. The invention has stable working and easy operation with beam lifting-moving functions.

Description

technical field [0001] The invention relates to construction engineering equipment, especially the box girder mobile trolley mainly used for lifting and lowering the prefabricated beam on the pedestal and moving on the track, and specifically applied to the lifting and lateral movement of the 32.6m and 24m box girders of the railway passenger dedicated line . Background technique [0002] At present, there is no box girder jacking and traversing operation equipment mainly used for railway passenger dedicated lines of 32.6m and 24m, with a carrying capacity of up to 900 tons. Therefore, along with the rapid development of my country's railway engineering, there is an urgent need for a box girder mobile trolley with a carrying capacity of about 900 tons. Contents of the invention [0003] The object of the present invention is to provide a box girder mobile trolley with beam lifting and beam moving functions, compact equipment structure, strong bearing capacity, stable beam...
