Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments.

Fig. 1 is a schematic structural view of a discharge device according to an embodiment of the present invention; fig. 2 is a schematic structural diagram of a first supporting plate according to an embodiment of the present invention; fig. 3 is a schematic view of a structure of a backing plate according to an embodiment of the present invention. As shown in fig. 1-3, comprising: the bridge 11, the upright post 2 and the upright post hoop 3; the upright post hoop 3 is arranged on the upright post 2, and a discharging device is arranged between the bridge frame 1 and the upright post hoop 3;

the unloading device comprises a top plate positioned at the upper end and a bottom plate positioned at the lower end; a vertical plate 4 is arranged between the top plate and the bottom plate;

the top plate comprises a first supporting plate 51, the front end and the rear end of the first supporting plate 51 are provided with first baffle plates 52, and two sides of the first supporting plate 51 are provided with first inclined surfaces 511; the bottom plate comprises a second supporting plate 61, the front end and the rear end of the second supporting plate 61 are provided with second baffles 62, and the two sides of the second supporting plate 61 are provided with second inclined surfaces 611;

the vertical plates 4 are arranged between the first inclined surface 511 and the second inclined surface 611 and are positioned on the inclined surfaces, and fastening devices are arranged between the vertical plates 4.

In detail, the existing upright post 2 is used for supporting the upper structure of the bridge, and the upright post hoop 3 is arranged above the upright post 2, so that a constructor can conveniently construct and operate on the upright post 2. The bridge frame 1 is used for the construction of the upper structure of the bridge and needs to be disassembled after the construction. Conventionally, a jack or other jacking equipment is directly mounted on the bridge frame 1 and the upright post hoop 3 to jack up the bridge frame 1, so as to adjust the height of the bridge frame 1, and then the disassembly process is completed. Great power equipment such as jack, there is error nature and uncertainty in manual operation when the dynamics of control jacking, leads to bridge frame 1 to appear the too big phenomenon of atress easily, influences the dismantlement effect.

The unloading device arranged between the bridge frame 1 and the upright post hoop 3 comprises a top plate positioned at the upper end and a bottom plate positioned at the lower end; a vertical plate 4 is arranged between the top plate and the bottom plate. The top plate comprises a first supporting plate 51, the front end and the rear end of the first supporting plate 51 are provided with first baffle plates 52, and two sides of the first supporting plate 51 are provided with first inclined surfaces 511; the bottom plate comprises a second supporting plate 61, the front end and the rear end of the second supporting plate 61 are provided with second baffles 62, and the two sides of the second supporting plate 61 are provided with second inclined surfaces 611; the riser 4 is mounted on the inclined surface between the first inclined surface 511 and the second inclined surface 611. In order to improve stability, inclined surfaces (not shown in the figures) matched with the inclinations of the first inclined surface 511 and the second inclined surface 611 are arranged at the positions where the two ends of the vertical plate 4 are contacted with the first inclined surface 511 and the second inclined surface 611, so that the installation is more stable, and the adjustment is more convenient. The first baffle 52 limits the riser 4 at both ends of the first support plate 51, and the second baffle 62 limits the riser 4 at both ends of the second support plate 61. The riser 4 can be adjusted in position manually on the first inclined surface 511 and the second inclined surface 611, that is, upward or downward along the inclined surfaces. It is of course also possible to provide ramps on the first and second

inclined surfaces

511, 611, which makes the movement more labour-saving. Meanwhile, the vertical plate 4 is respectively inclined with the contact surfaces of the first inclined surface 511 and the second inclined surface 611 in a matched manner, so that gapless fit can be guaranteed. The inclination angles of the first inclined surface 511 and the second inclined surface 611 are set according to actual conditions. As shown in fig. 2, in order to have a better spacing effect, each first baffle 52 further extends to the outer side of the first supporting plate 51.

In detail, a fastening device is arranged between the vertical plates 4 and used for fixing the vertical plates 4 after the positions are adjusted. For convenient operation, the fastening device further comprises threaded holes provided on each riser 4, and threaded rods 45 are installed through the threaded holes. Of course the fastening means may be of other configurations. Meanwhile, in consideration of the fact that the use effect of the threaded rod 45 can be increased, further, a base plate 451 is arranged at the position where the threaded rod 45 is installed with the threaded hole. In order to reduce the wear on the first support plate 51 and the second support plate 61, further, the upper end of the first support plate 51 and the bottom of the second support plate 61 are provided with wear pads.
