[0006] Furthermore, a protective enclosure is provided at the top edge of the top beam body.

[0007] Furthermore, extension plates are hinged at both ends of the top beam body, respectively. The extension plates can be connected to a hydraulic working system and unfolded at both ends of the top beam body to perform corresponding supporting operations.

[0008] Furthermore, elastic connecting rods are connected between the side surfaces of the adjacent split panels, and the elastic connecting rods have corresponding elastic deformation forces and are adaptively stretched and deformed with different adjustment heights of the split panels.

[0009] Furthermore, a connector is provided at the bottom of the top beam body for connecting to a corresponding hydraulic lifting system.

[0010] Furthermore, the bottom of the floating baffle is connected to a pressing plate via a connecting column.

[0011] After adopting the above structure, the utility model has the following beneficial effects:

[0023] like Figure 1-5 As shown, a top beam of a hydraulic support for chute support includes a top beam body 1 and a split plate 6; the top beam body 1 has corresponding supporting force, and a protective enclosure 8 is arranged at the top edge of the top beam body 1, and the top height of the protective enclosure 8 is not higher than the lowest downward end of the split plate 6; and the two ends of the top beam body 1 are respectively hinged with extension plates 9, and the extension plates 9 can be connected to the hydraulic working system and unfolded at the two ends of the top beam body 1 to perform corresponding supporting operations.

[0024] The interior of the top beam body 1 is hollow to form a accommodating chamber, in which a plurality of partitions 2 are arranged along the length direction of the top beam, and the plurality of partitions 2 separate the accommodating chamber to form a plurality of adjacent adjusting chambers 3; a floating baffle 4 is arranged at the lower part of the adjusting chamber 3, and the floating baffle 4 slides along the two sides of the adjusting chamber 3 within the corresponding height range, and a filling chamber for filling elastic filler is formed between the bottom of the floating baffle 4 and the bottom wall of the adjusting chamber 3; the elastic filler filled in the filling chamber is a whole, and can be an elastic filling layer formed by multiple layers of polyurethane elastic layer and rubber layer, which has corresponding elastic deformation force and recovery performance, and performs corresponding extrusion deformation when the floating baffle 4 is pressed downward by force, and exerts corresponding reverse force on the floating baffle 4; here, preferably, the floating baffle 4 floats up and down, and the two sides of the corresponding adjusting chamber 3 are respectively provided with limit grooves 5, and the two sides of the floating baffle 4 are inserted into the limit grooves 5, and in addition, the bottom of the floating baffle 4 is connected to a pressing plate 11 through a connecting column, and the pressing plate 11 abuts against the top of the elastic filler (layer).

[0025] In some preferred embodiments, the split plate 6 is erected above the top beam body 1 through the adjusting column 13 and corresponds one-to-one with the adjusting cavity 3. It should be noted here that the split plate 6 is hinged to the top end of the adjusting column 13, and the bottom end of the adjusting column 13 movably penetrates the top wall of the accommodating chamber and is fixed on the top wall of the floating baffle 4; the split plate 6 is hollow inside and forms a plurality of rolling cavities along the length direction of the top beam body 1, and the two ends of the rolling cavity extend to both sides of the length direction of the top beam body 1 respectively, and a support roller shaft 7 is rotatably installed between the two ends in the rolling cavity, and the side section of the support roller shaft 7 is on the same horizontal plane as the top end of the split plate 6. When the hydraulic lifting system connected to the bottom of the top beam body 1 performs corresponding lifting and supporting operations, the split plate 6 supports the top plate respectively, and for the uneven tunnel top plate, the floating baffle 4 at the bottom is pressed to deform the elastic filling layer (object) in the elastic filling cavity, and the split plate 6 adaptively performs corresponding supporting operations respectively.

[0026] It should be noted here that a connecting head 12 is provided at the bottom of the top beam body 1 for connecting the corresponding hydraulic lifting system.

The elastic connecting rods 10 have corresponding elastic deformation forces and are adaptively stretched and deformed with different adjustment heights of the split plates 6. In the tunnel roof with uneven stress distribution, adjacent split plates 6 are connected by elastic connecting rods 10, which can form mutually balancing tensions on both sides of the split plates 6, avoiding sudden stress changes that lead to acceleration of rapid downward pressure on the split plates 6, thereby improving the stability of the support operation.

[0028] When in use, during support, the top beam body 1 is lifted accordingly through the operation of the hydraulic lifting system, and the split plate 6 rises synchronously with the top beam body 1. The split plates 6 respectively support the corresponding top plate positions, and press down the elastic filling layer through the floating baffle 4. The elastic filling layer is deformed accordingly under the force and exerts a reverse force on the floating baffle 4, so as to adjust the support height in a small range on the uneven top plate, increase the contact surface with the top plate during support, and improve the support effect;

[0029] When the rack is moved, the support roller shaft 7 at the top of the split plate 6 can be rotated accordingly to reduce the sliding friction between the top beam and the top plate, thereby reducing the friction damage to the top plate.
