Problems solved by technology
[0003] However, most of the traditional retaining seats adopt L-shaped casting structure. The welding between the retaining seat and the main reinforcement of the base consists of two welds. As a result, the retaining seat has to bear the torsional force transmitted by the column pressure plate. Once there is a problem with the welding quality between the retaining seat and the main rib of the base, the torsional force is greater than the welding strength, and the retaining seat will have an open welding failure.

The invention provides a hydraulic support column pressing plate fixing mechanism and a hydraulic support. The hydraulic support column pressing plate fixing mechanism comprises a base main rib, a column pressing plate, and a stop seat, wherein the column pressing plate is connected with the base main rib, and one end of the column pressing plate is fixed on the base main rib and the other end ofthe column pressing plate is movably arranged on the base main rib; the stop seat is welded on the base main rib and located above the other end of the column pressing plate to stop the other end of the column pressing plate from moving upwardly; and the stop seat comprises a base and a rib arranged on the base, and the base and the rib are welded on the base main rib for increasing the welding length between the stop seat and the base main rib. According to the hydraulic support column pressing plate fixing mechanism provided in the invention, the welding length between the stop seat and thebase main rib is increased, the welding strength between the stop seat and the base main rib is further enhanced, and the problems that the welding length between the stop seat and the base main rib is short, the number of welding seams is small, cracking failure happens easily and the like in a related technology can be solved.
Description
technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a hydraulic support column pressure plate fixing mechanism and a hydraulic support. Background technique [0002] The column pressure plate of the hydraulic support is an important structure to prevent the column from axially rotating and detaching from the base column socket, and to ensure the normal operation of the hydraulic support column. One end of the existing column pressure plate is provided with a stop structure, which is used to limit the axial rotation of the column pressure plate and Move up. [0003] However, most of the traditional retaining seats adopt L-shaped casting structure. The welding between the retaining seat and the main reinforcement of the base consists of two welds. As a result, the retaining seat has to bear the torsional force transmitted by the column pressure plate. Once there is a problem with the welding quality between the retaining...
