The specific embodiment 1 of the segment unloading device with the automatic deviation rectifying function provided by the utility model comprises the following steps:

as shown in fig. 1 to 4, the segment unloading device 100 includes two side unloading frames 1, the two side unloading frames 1 extend in the left-right direction, where the left-right direction corresponds to the tunnel width direction, and correspondingly, the direction corresponding to the tunnel length direction on the two unloading frames 1 is defined as the front-rear direction, and each side unloading frame 1 is of a gantry structure, and includes two side columns 11, i.e., a front side column and a rear side column, which are spaced apart in the front-rear direction, and a cross beam 16 located at the tops of the two side columns 11.

And a segment lifting mechanism is respectively arranged on each side unloading frame 1, and the segment lifting mechanisms on the unloading frames 1 on the two sides are matched to unload the segments 2 on the segment transport vehicle 200. The segment lifting mechanism comprises a lifting frame 13 and lifting oil cylinders 17, wherein the lifting frame 13 is correspondingly assembled on the two side upright posts 11 of the corresponding side unloading frame 1 in a guiding manner along the vertical direction, and the lifting oil cylinders 17 are arranged between the lifting frame 13 and cross beams 16 of the corresponding side oil cylinders and are used for driving the lifting frame 13 to lift. Each plays to rise still to be provided with swivel bracket 14 on the frame 13, swivel bracket 14 is used for in the horizontal plane internal rotation in order to remove to the section of jurisdiction 2 below of waiting to rise, swivel bracket 14 is by corresponding rotatory hydro-cylinder drive, when needing to play to rise section of jurisdiction 2, rotatory hydro-cylinder drive swivel bracket 14 swings to corresponding section of jurisdiction 2 below, plays to rise frame 13 and plays to rise, can play to rise corresponding section of jurisdiction 2. Because the segments 2 on the segment transport cart 200 are generally stacked together in a vertically fixed manner, all segments can be lifted upwards in a translation manner when segment lifting mechanisms on two sides are used for lifting the segments in a matching manner.

In addition, a plurality of segment centering units are sequentially distributed on the unloading frames 1 on the two sides at intervals along the up-down direction, and the number of the segment centering units is three in the attached drawing. In specific implementation, the corresponding number of the segment centering units can be configured according to the number of the segments which are transported conventionally. Every section of jurisdiction centering unit is used for corresponding a section of jurisdiction of centering adjustment, and every section of jurisdiction centering unit includes both sides section of jurisdiction centering structure respectively, and both sides section of jurisdiction centering structure sets up on both sides unloading frame 1 one-to-one. Each side segment centering structure comprises two centering piston cylinders, specifically, two centering oil cylinders 12, wherein the two centering oil cylinders 12 are distributed at intervals in the front-back direction so as to be correspondingly arranged close to the front end and the back end of the segment 2.

In fact, in each side segment centering structure of a segment centering unit, two centering cylinders 12 are fixedly arranged on the opposite outer sides of two side columns 11 of one side unloading frame 1 in a one-to-one correspondence manner, outer supports 15 are fixedly welded on the opposite outer sides of the two side columns 11 corresponding to the corresponding centering cylinders 12, and each outer support 15 is provided with one centering cylinder 12. The cylinder body of the centering oil cylinder 12 is fixedly arranged on the corresponding outer support 15, the piston rod of each pair of the middle oil cylinders 12 is used as a centering pushing piece, the straight reciprocating motion is carried out in the horizontal plane to push the corresponding segment 2 to the middle of the unloading frames 1 at the two sides, and the centering pushing pieces of the centering oil cylinders 12 at the two sides in the same segment centering unit have pushing centering positions in the reciprocating motion process, so that the segment 2 is pushed to be adjusted to the corresponding centering position, and the segment crane 300 can conveniently and automatically grab the segment 2.

It should be particularly noted that, in this embodiment, for three segment centering units, two segment centering units that are arbitrarily adjacent in the up-down direction are an upper segment centering unit and a lower segment centering unit, and a piston rod of the centering cylinder 12 in the upper segment centering unit and a piston rod of the centering cylinder 12 in the lower segment centering unit are spaced at a set distance in the up-down direction for corresponding to two corresponding segments 2 stacked on the segment lifting mechanism, so as to facilitate simultaneous centering adjustment of the segments 2 stacked up and down.

As shown in fig. 5 and fig. 6, the tube piece unloading device 100 provided in this embodiment is installed corresponding to the tube piece crane 300 when in use, and when the tube piece 2 transport vehicle transports the tube piece 2 to the lifting position of the tube piece 2 unloader, the tube piece 2 unloader unloads the tube piece 2 from the tube piece transport vehicle through the lifting frame 13 and the rotating bracket 14, and the tube piece 2 transport vehicle drives away from the tube piece 2 unloading area. Corresponding to the segment 2 with a plurality of stacked segments, the centering oil cylinder 12 of the segment centering unit can be used for centering and adjusting the segment 2.

When all the segments 2 are wholly deviated from the central line of the tunnel to form all the deviations as shown in fig. 7, the centering oil cylinders 12 of all the segment centering units can be controlled to push all the segments 2 inwards together, so that all the segments 2 can be wholly adjusted to the central line position of the tunnel to realize centering operation, the position error of the adjusted segments 2 is within the grabbing error range of the segment crane 300, and the segment crane 300 is ensured to normally grab the segments 2.

When only a single segment 2 is inclined as shown in fig. 8, taking the deviation of the topmost segment 2 from the center line of the tunnel as an example for illustration, the centering cylinder 12 corresponding to the segment 2 can be controlled to extend out, the topmost segment 2 is adjusted to the center line of the tunnel, and the position error of the adjusted segment 2 is within the grabbing error range of the segment crane 300, so that the segment crane 300 can normally grab the segment 2.

It should be noted that, if only the segment 2 at the middle or bottom is deflected, the segment crane 300 is needed to grab the segment centered at the upper part, and then the deflected segment is adjusted, that is, when the deflection of a segment is adjusted, it is necessary to ensure that the segment is not laminated on the upper layer.

When as shown in fig. 9, when the segment 2 is deflected in the plane direction to form a skew state, the centering cylinder 12 can be extended out integrally, the segment 2 is adjusted to the central line position of the tunnel integrally, and the position error of the adjusted segment 2 is within the grabbing error range of the segment crane 300, so that the segment crane 300 can normally grab the segment 2.

Of course, if a certain segment 2 deflects along the plane direction, the corresponding centering cylinder 12 can also be extended to perform centering adjustment. Likewise, it is desirable to ensure that no other segments 2 are stacked on this segment 2.

It needs to explain very much that, the section of jurisdiction centering structure on above-mentioned every side unloading frame all is unilateral to middle with the section of jurisdiction top to intermediate position, and the action range that the accessible set up section of jurisdiction centering structure realizes that this is that technical staff in the field realizes easily, and section of jurisdiction centering structure on the unloading frame of both sides cooperates, can guarantee that the section of jurisdiction is accurate centering.
