Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
The utility model relates to a hydraulic dismounting device for a tamping pick of a tamping vehicle, which is shown in figures 1, 2 and 3, wherein the figures are respectively marked as follows: the tamping tool comprises a body 1, a top block 2, an oil filling port 3, a tamping arm lower wall 4, a tamping pick upper supporting body upper wall 5, a tamping arm 6, a tamping pick 7, a tamping pick upper supporting body 8, a first groove 9, an elastic sealing device 10, a second groove 11 and a magnetic device 12.
The hydraulic dismounting device for the tamping pick of the tamping vehicle comprises a body 1, a top block 2 and an oil injection port 3, wherein the body 1 is hollow, and the top block 2 is respectively connected to the upper part and the lower part of the interior of the body 1 in a sliding manner; the outer end surface of the top block 2 is respectively in contact connection with the lower wall 4 of the tamping arm 6 and the upper wall 5 of the upper support body 8 of the tamping pick 7; a hydraulic oil inlet and outlet 3 is formed in the middle of one side of the body 1, the hydraulic oil inlet and outlet 3 is connected with a hydraulic system, and threads are formed in the hydraulic oil inlet and outlet 3 for connecting the hydraulic system conveniently; in order to ensure that the device is safe and simple and avoid the device loss after the tamping pick is disassembled, the other side of the body 1 is provided with a magnetic device 12, and the body 1 is connected with the tamping pick 7 through the magnetic device 12.
The jacking block 2 is provided with a first groove 9, and an elastic sealing device 10 is arranged in the first groove 9 and used for sealing hydraulic oil; the elastic sealing device 10 has strong elasticity and can press the inner wall of the body 1, so that the sealing effect can be well achieved.
