The front end ear plate 160 is disposed in the same manner as the rear end ear plate 170. For example, the front end ear plates 160 are arranged in four ways, wherein two front end ear plates 160 are arranged along one end of the Y direction, the two front end ear plates 160 are respectively attached to the two adjacent main ribs 114, and the front end ear plates 160 are further welded to the top plate 112. The other ends of the two front end ear plates 160 along the Y direction are disposed, and are not described in detail herein.

Example 11

As shown in fig. 3 and 5, the embodiment provides a top beam 100 and a hydraulic support 10, in a supporting area, the top beam 100 is an integrated structure and can effectively cover a reversed loader, the left and right sides of the top beam 100 are hinged with side guards 120, the front end is hinged with a front beam 500, the rear end is hinged with a rear beam 600, the lower part of the top beam 100 is provided with an ear plate seat 130, and a hinged inclined beam 300.

As shown in fig. 5, the integrated top beam 100 is supported by four upright posts 200, after the top beam 100 bears the pressure of the roadway roof, the pressure is transmitted to the four upright posts 200 through the four sets of post caps 140, the piston rods of the upright posts 200 are connected with the post caps 140 by pin shafts, the hydraulic system controls the four upright posts 200 to synchronously ascend and descend, and the lug plate seats 130 and the oblique beams 300 are connected by optical axes.

As shown in fig. 3, the integrated top beam 100 is a top beam structural member formed by welding high-strength steel plates, and has a box-shaped structure inside, and on the basis of the top plate 112, a plurality of groups of main ribs 114 are designed in the length direction, and transverse ribs 118 are arranged in the width direction, and the open end of the box-shaped structure is welded by using the cover plate 116, and the top plate 112, the main ribs 114 and the transverse ribs 118 are welded by fillet welds, and the cover plate 116 and the main ribs 114 are welded by groove welds. Side ear plates 150 are welded on the left side surface and the right side surface of the top beam body and used for being hinged with the side guard plates 120, mounting holes are designed at the front end and the rear end and used for being hinged with a front beam, ear plate seats are designed at the bottom of the top beam 100 and used for being connected with an oblique beam 300, two groups of column caps 140 are symmetrically arranged on the left side and the right side of the top beam 100 respectively, and hoisting holes 180 are reserved at four corners of the top beam 100 so as to facilitate.

As shown in FIG. 4, the top plate 112 is formed by splicing two steel plates, and a splice plate 114 is designed at the position of a splice seam in the middle of the top plate 112 to serve as a reinforcing flitch. The lug plate seat 130 hinged with the oblique beam 300 is designed below the top beam 100, in order to improve the torsional strength and the bearing pressure, a reinforcing attachment plate 134 is welded on each group of main lug plates 132, a U-shaped cover plate and a middle stop pin plate are designed to be connected with the middle two groups of main lug plates 132, the U-shaped cover plate is a guard plate 136, and the middle stop pin plate is a stop plate 138. The left two groups of main ear plates 132 are hinged with the oblique beam 300 through a pin shaft, the right two groups of main ear plates 132 are hinged with the oblique beam 300 through a pin shaft, and therefore the four groups of main ear plates 132 are hinged with the oblique beam 300, the structural stress is better, and the coaxiality of the four groups of mounting holes in the main ear plates 132 needs to be guaranteed.

In summary, the beneficial effects according to the embodiments of the present invention are:

1. the box 110 is spliced into an organic whole structure by a plurality of box units 1102, can increase the protection area of hydraulic support 10, avoids the middle part waste rock that drops, and but the back timber 100 of integral type is in the in-process that is used for supporting the tunnel roof whole action to applicable in the bad condition of tunnel roof roughness, it is stronger to the adaptability of tunnel roof, the pressure that transmits down on the tunnel roof can transmit on back timber 100 more evenly.

2. The arrangement of the ear plate seat 130 improves the torsion resistance and ensures that the inclined beam 300 is well stressed.
