Problems solved by technology
The transverse ribs are intersected with the longitudinal main ribs and the longitudinal ribs. According to the technical standard, the cover plate needs to sink 3mm relative to the main rib plate. The cross rib plate divides the cover plate and the top plate at the wedge-shaped leading edge into multiple parts that need to be welded separately. The plate block, resulting in the complex structure of the wedge-shaped front part of the top beam, the manufacturing process is time-consuming and costly, which is not conducive to improving production efficiency
In addition, there are too many welds produced at the wedge-shaped leading edge, the mechanical performance is not good and the weight of the top beam is increased

The invention provides a hydraulic support and a top beam thereof. The top beam of the hydraulic support provided by the invention comprises a top plate, a cover plate, a longitudinal main rib and a longitudinal reinforced rib, wherein the longitudinal main rib is used for connecting the top plate with the cover plate, and the longitudinal reinforced rib for connecting the top plate with the cover plate is arranged corresponding to the wedge-shaped front edge part of the top beam; the side face, facing the cover plate, of the longitudinal reinforced rib is provided with at least one first convex tooth, a first concave hole matched with the first convex tooth is formed on the cover plate, and the first convex tooth and the first concave hole are welded together; and / or the side face, facing the top plate, of the longitudinal reinforced rib is provided with at least one second convex tooth, a second concave hole matched with the second convex tooth is formed on the top plate, and the second convex tooth and the second concave hole are welded together. The hydraulic support provided by the invention is provided with the top beam. By utilizing the technical scheme in the invention, the hydraulic support and the top beam have the advantages of simple structure, low manufacturing difficulty, material conservation, convenience in maintenance and improved production efficiency.
Description
technical field [0001] The invention relates to the field of coal machinery, more specifically, to a hydraulic support and a top beam thereof. Background technique [0002] The hydraulic support is a support device for fully mechanized mining face, its main function is to support the stope roof and maintain a safe working space. The roof beam of the hydraulic support in the prior art mainly includes a roof plate, a cover plate, and a plurality of longitudinal main ribs connected between the roof plate and the cover plate and running through the entire roof beam longitudinally. The rear part of the top beam is provided with a plurality of transverse ribs perpendicular to the longitudinal main ribs, and the transverse ribs, the longitudinal main ribs, the top plate and the cover plate form a box structure part for cooperating with the pillars. The front part of the top beam is a wedge-shaped front part with variable cross-section, and the spaces on both sides of each longitud...
