The utility model discloses an oil seal assembling device capable of preventing a rubber lip from being overturned reversely, which is characterized in that the section of a tool base is U-shaped, a vertical arm of a T-shaped oil seal expanding shaft penetrates through the bottom edge of the base and can move up and down on the base, and a groove for accommodating an inner ring of a dust cover is formed in the upper surface of a cross arm of the T-shaped oil seal expanding shaft; the oil seal fixing tool is placed above the tool base, the section of the oil seal fixing tool is in an inverted U shape, an oil seal fixing groove is formed in an opening of the lower end of the oil seal fixing tool, the press-fitting tool is installed in the oil seal fixing tool, and the section of the press-fitting tool is in an inverted T shape. A vertical arm of the inverted-T-shaped press fitting tool penetrates through the bottom edge of the oil seal fixing tool and can move up and down in the oil seal fixing tool. A limiting groove is formed in an upper opening of the tool base. The oil seal assembling machine has the advantages of being capable of achieving automatic assembling of the oil seal and the dustproof cover of the oil seal, and preventing the lip of the oil seal from being reversely turned over in the reverse direction and preventing the oil seal from being damaged during manual operation.

The utility model relates to the technical field of track lifting devices, in particular to a track maintenance track lifting device which comprises a base, the base is arranged to be in an inverted T shape, two L-shaped plate grooves are formed in the side face and the bottom of a vertical portion of the base, two through holes are formed in the top of the base and communicated with the top ends of the two plate grooves respectively, and the two through holes are communicated with the top ends of the two plate grooves respectively. Two through holes are formed in the base, two plate grooves are formed in the base, lifting frames are movably inserted into the two plate grooves, the top ends of the two lifting frames penetrate through the two through holes respectively, top plates extending backwards are fixedly installed at the top ends of the two lifting frames, and a hydraulic mechanism is arranged between the top of the transverse straight part on the rear portion of the base and the top plates. And then a handle is shaken to enable the hydraulic cylinder to push the top plate to move upwards, so that the two lifting frames are driven to lift the rails, when the rails fall, the hydraulic rod is controlled to push the push plate, the push plate pushes the rails on the two lifting frames to move, and therefore the positions of the rails are adjusted.

The application discloses a vertical amusement wind tunnel, which comprises a driving system (1), a tunnel body (2), a pry block system (5) and auxiliary facilities. The tunnel body (2) is in an inverted T shape. The driving system is provided in two sets and symmetrically installed on two sides of the tunnel body (2). The driving system (1) and the tunnel body (2) are both installed on the pry block system (5). The auxiliary facilities comprise a step ladder (3) and a sightseeing platform (4). The sightseeing platform (4) is arranged around the vertically upward extending part of the tunnel body (2). The step ladder (3) is arranged on the other side of the driving system. The pry block system (5) is in contact with the ground and comprises a tunnel body pry block (9), a small pulley pry block (11), an engine pry block (18) and a small bearing seat pry block (24).
