The invention discloses a bridge. The bridge comprises a high pier, a support and a body; the high pier is connected with the bottom of the body through the support; the support comprises an upper support plate and a lower box seat; a rail for a high speed train to run is arranged on the body; a vibration eliminating device for absorbing and eliminating the vibration of the body is arranged in thesupport; the vibration eliminating device comprises two spherical rotating blocks which are symmetric to each other at the top and the bottom; the upper spherical rotating block is fixedly connectedwith the support support plate; the lower spherical rotating block is fixedly connected with the lower box seat; the upper spherical rotating block and the lower spherical rotating block are propped against each other; and a vibration absorbing structure for absorbing the vibration of the body is arranged in the high pier. The bridge has the advantages of high stability, perfect body supporting effect, vibration absorption and practicability.

A gas damping type shock absorption pipe clamp for a hydraulic pipeline is mainly characterized in that a lower pipe clamp is arranged on a lower pipe clamp cover plate, and the upper portion of the lower pipe clamp is provided with a semicylindrical groove with the open side up; an upper pipe clamp matched with the lower pipe clamp is arranged above the lower pipe clamp, and the middle of the upper plane of the upper pipe clamp is provided with a threaded hole in threaded connection with the lower end of a plunger rod; the plunger rod is arranged in a central through hole of the upper pipe clamp cover plate, and a guide seal component is arranged between the plunger rod and the central through hole of the upper pipe clamp cover plate; the upper periphery of the plunger rod is provided with a combined slide ring seal part in contact with the central through hole of the upper pipe clamp cover plate, and the central through hole of the upper pipe clamp cover plate is in threaded connection with the lower portion of a gas cylinder; a gas check valve and a damping part are arranged in two threaded holes of the lower portion of the gas cylinder respectively, and the upper end of the gas cylinder is provided with an inflation valve; the upper pipe clamp cover plate, the upper pipe clamp, the lower pipe clamp and the lower pipe clamp cover plate are connected through two screw rods. The gas damping type shock absorption pipe clamp for the hydraulic pipeline has the advantages that the defects of low reliability and high impact of a traditional pipe clamp to a pipeline system are overcome, and vibration of the hydraulic pipeline can be well eliminated.

The invention relates to the technical field of backpacks and travelling bags, in particular to an air pressure suspension device of a backpack. The invention includes two sliding bars which are provided with an upper support plate and a lower support plate. At least one air bag type pneumatic pump is arranged between the upper support plate and the lower support plate. The two ends of the air bag type pneumatic pump are respectively connected with the upper and the lower support plates. The invention can be mounted on the back part of the bag. When people climb mountain or walk with heavy burden, the upper and the lower support plates move reversely because of the gravity action of the backpack. The air in the air bag type pneumatic pump is pressed, which causes back pressure, and consequently, realizes suspension effect. People climbing mountain or walking do not feel the pressure of the different gravity of the backpack. Moreover, the invention can be mounted on the backpacks of different designs and can be changed by the user conveniently. Individual requirements of the users can be satisfied.
