Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

Referring to fig. 1 to 5, a turning device for a bridge top web includes: at least two flipping elements 810 spaced apart by a predetermined distance; wherein the flip assembly 810 comprises: the device comprises a machine frame 811, two overturning pieces hinged at the middle position of the machine frame 811, and an encoder 812 which is arranged on the machine frame 811 and is in transmission connection with the overturning pieces. Wherein, the upset piece includes: a rotating shaft 813, a turning arm 814 and a cylinder 815. Wherein, the rotating shaft 813 is arranged at the middle position of the frame 811; the cross-sectional shape of the flip arm 814 is "L" or approximately "L"; it includes: a main body 814a, a bent portion 814b provided at the bottom of the main body 814a and bent at a predetermined angle toward the cylinder 815, and a mounting hole provided at the connection between the main body 814a and the bent portion 814b and rotatably mounted on the rotating shaft 813; the oil cylinder 815 is hinged inside the frame 811, and the other end is hinged with the bottom of the turning arm 814.

Wherein, the turning arm 814 is pulled or pushed by the oil cylinder 815 to rotate along the rotating shaft 813 between being perpendicular to the rack 811 and being parallel to the rack 811; that is, the single flip arm 814 of the flip assembly 810 can be flipped by plus or minus 90 degrees, and can be opened horizontally, and each flip arm 814 can be controlled independently.

In a further embodiment, the body portion 814a is further provided with a plurality of locating pins 814c. Because the bridge top web comprises antinode board A and roof B welding, and antinode board A perpendicular to roof B, the cross sectional shape of bridge top web is "T" shape, if direct upset, then can lead to bridge top web slope, consequently sets up a plurality of locating pins 814c on upset arm 814, just locating pin 814c highly just equals the distance between roof B curb plate to the welding seam, so can let bridge top web keep horizontal placing, conveniently detect and restore bridge top web.

In a further embodiment, referring to fig. 6, the rotating shaft 813 is provided with a synchronizing gear 813a at a position close to the rotating shaft 813, and the synchronizing gear 813a is meshed with a coding gear 812a of the encoder 812; the encoder 812 is a dual output rotary encoder 812. The rotary encoder 812 may output two groups of pulses with a phase difference of 90 degrees, and the two groups of pulses may be used to measure the rotation speed and determine the rotation direction. The motion state of the detecting flip arm 814 can be determined by comparing whether phase a is before phase B or before phase B to determine whether the encoder 812 rotates in the forward or reverse direction.

In a further embodiment, the flipping elements 810 are distributed at predetermined intervals between the transfer devices 100, wherein the transfer devices 100 are roller-type transfer mechanisms. When a plurality of upset subassemblies 810 cooperate the use, detect the motion state of upset arm 814 through the encoding wheel, automatic control upset arm 814 synchronous operation guarantees whole turning device's synchronism, makes the steady upset of bridge top web.

In order to facilitate understanding of the technical scheme of the turnover device for the bridge top web, the working principle of the turnover device is briefly explained: the bridge top web is transmitted to a processing station of the turnover device through the transmission device 100, in the turnover process, a single turnover assembly 810 is used for illustration, the bottom of the bridge top web is placed on a turnover arm 814 in a horizontal state, the side surface of a corrugated plate is located on one side of the other turnover arm 814 in a vertical state, and the corrugated plates are abutted through manually adjusting the position of a positioning pin 814c on the turnover arm 814 in the vertical state; then the turning arm 814 is pulled or pushed by the oil cylinder 815 to rotate along the rotating shaft 813 between the position perpendicular to the rack 811 and the position parallel to the rack 811; originally, the rotatory 90 degrees of upset subassembly 810 in the bottom of bridge top web become vertical state, originally the rotatory 90 degrees of upset piece of one side of position bridge top web become the horizontality, realize the upset of bridge top web, and the bridge top web after the upset is in the level and places the state, and the convenience is detected and is restoreed bridge top web.

Because the length of the top web of the bridge is large, a plurality of turnover assemblies 810 are required to be adopted for matching turnover; when a plurality of upset subassemblies 810 used when a plurality of upset subassemblies 810 cooperation, through the motion state of encoding wheel detection upset arm 814, automatic control upset arm 814 synchronous operation guarantees whole turning device's synchronism, makes the steady upset of bridge roof web.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
