[0024] Among them, the adjustment mechanism 4 includes an adjustment component 41, and the adjustment component 41 is installed inside and on one side of the fixed frame 3, the adjustment component 41 includes a transmission screw 411, and the transmission screw 411 is installed at the inner center of the fixed frame 3, a bevel gear 1 412 is fixed around one end of the transmission screw 411, and a bevel gear 2 413 is meshed on one side of the bevel gear 1 412, a rotating rod 414 is fixed in the middle of the bevel gear 2 413, and a motor 415 is connected to one end of the rotating rod 414, a screw sleeve 416 is screwed around one side of the transmission screw 411, and sliding frames 417 are fixed on both sides of the screw sleeve 416, and the two inner sides of the fixed frame 3 are fixed to the screw sleeve 416. A guide rod 418 for guiding the movement of the sliding frame 417 is fixed on the side, and a lifting column 419 is fixed on the upper middle part of the two sliding frames 417. The guide rod 418 is symmetrically distributed along the vertical center axis of the transmission screw 411. A stabilizing component 42 is installed on one side of the top of the two lifting columns 419. The stabilizing component 42 includes a fixing sleeve 421, and the fixing sleeve 421 is fixed to the top periphery of the two lifting columns 419. A connecting slide 422 is fixed on one side of the two lifting columns 419. A fixing plate 424 is fixed on one side of the upper side of the base frame 1, and guide grooves 423 for guiding the movement of the connecting slide 422 are opened on both sides of the inner side of the fixing plate 424. The base frame 1 is located at one point After the fixation is completed, the staff can start the motor 415 to rotate the rotating rod 414 and the bevel gear 2 413 at one end thereof according to the different types of vehicles on the track. At this moment, the bevel gear 1 412 meshing on one side of the bevel gear 2 413 will drive the transmission screw 411 to rotate. At this moment, the screw sleeve 416 acting on the screw will drive the sliding frames 417 on both sides to cooperate with the guide rod 418 to guide the interior of the fixed frame 3 to perform the ascending operation. Since the two sliding frames 417 are fixed with a lifting column 419 on the top, and the top of the lifting column 419 is connected to the hydraulic cylinder 5, the purpose of adjusting the height of the hydraulic mechanical buffer assembly can be achieved under the drive of this adjustment assembly 41.

At this time, the screw sleeve 416 acting with the screw will drive the sliding frames 417 on both sides to cooperate with the guide rod 418 to guide the internal part of the fixed frame 3 to perform the rising operation. Since the two sliding frames 417 are fixed with jacking columns 419 on top, and the jacking columns The top of 419 is connected to the hydraulic cylinder 5, so the height of the hydraulic mechanical buffer assembly can be adjusted under the drive of this adjustment component 41, so that the rubber buffer plate 7 can be aligned with the corresponding buffering point of the rail car. Among them, a fixing sleeve 421 and a connecting slide 422 are provided around the top and one side of the two jacking columns 419. When the jacking column 419 rises with the hydraulic mechanical buffer assembly, its connecting slide 422 will also move guided by the guide groove 423 on the inner side of the fixing plate 424. When the rail car contacts the rubber buffer plate 7, under the buffering premise of the hydraulic cylinder 5 and the hydraulic rod 6, its connecting slide 422 will also tightly press against the end of the jacking column 419 to avoid excessive pressure on the rail car causing the jacking column 419 fixed with the hydraulic cylinder 5 to tilt and other safety-affecting phenomena, thereby reducing safety hazards.
