The utility model provides a servo drawer-type stereo garage comprising a garage body. A lifting well is arranged in the middle of the garage body, and a lifting support is arranged in the lifting well and is connected with a winch through slings. At least two layers of floor plates are arranged on each of two sides of the lifting well. Each layer floor plate is provided with storerooms, entrances of the storerooms face the lifting well respectively, and a vehicle carrying plate is arranged in each storeroom. Guide wheels are arranged at the bottom of each vehicle carrying plate. Fixed guide rails are arranged at the bottoms of the storerooms, the guide wheels travel along the fixed guide rails. A lifting guide rail is arranged on the top face of the lifting support, and can be abutted against with the fixed guide rails in the storerooms on two sides when being lifted together with the lifting support. A cross arm is mounted on the lifting support. A cross-arm driving device can drive the cross arm to move back and forth along the lifting support. Gears are mounted at two ends of the cross arm respectively. Racks are arranged at the bottoms of the vehicle carrying plates respectively. The gears can be meshed with the racks arranged at the bottoms of the vehicle carrying plates after moving into the storerooms with the cross arm, and are connected with a power device respectively. The servo drawer-type stereo garage can overcome the defects of existing stereo garages.

The invention relates to the field of rail vehicle gauge change, and discloses a moving disc assembly for a gauge changing wheel set. The moving disc assembly includes a moving disc and a bearing. A connecting hole outside the through hole; the outer ring of the bearing is fastened in the central through hole, and the inner ring of the bearing is used to be fixedly sleeved on the outer hub of the wheel. The moving plate assembly of the present invention has a simple structure, can be fastened on the wheel, and occupies less space on the wheel. The moving plate is pushed or pulled by the lateral drive mechanism to drive the wheel to move, thereby realizing wheel gauge change and large torque transmission , high reliability, improves the reliability of gauge change, and improves the efficiency of track change.

The invention discloses a large-span steel concrete combined truss girder side position transverse movement and girder dropping construction method. The construction method comprises the following steps of (1) measuring whether two slide way girder axels to be parallel, (2) installing a pulling transverse-moving system, (3) conducting main point pilot transverse movement outside railway clearance, (4) locking the main point to conduct formal transverse movement construction according to the pilot transverse movement data, (5) installing a girder-dropping steel support pier, a temporary protection pier and a girder-dropping jack on a pier top cap after the girder body is transversely moved to a designed position, then detaching a slide boat, a spherical steel bearer and a slide way beam. In the second step, the pulling transverse-moving system comprises an upper slide way, a lower slide way and a traction device, wherein the upper slide way is formed by the spherical steel bearer and the slide boat; the lower slide way is formed by two slide way beams; the slide boat of the upper slide way is buckled on the lower slide way; the traction device is connected with the slide boat on the transverse-movement front end via a steel strand; in the fifth step, two ends of the beam body conduct alternative girder-dropping; the spherical steel bearer is mounted on the lower part of the beam body; the spherical steel bearer falls on a supporting pinner; and the girder-dropping is in place.

The invention discloses a transverse moving type hydraulic rerailer. A rerailing beam is in a groove-shaped structure with an upward opening, and two sliding rails are fixed to the top ends of two side plates of the rerailing beam in the full length; a moving table capable of sliding left and right is arranged on the sliding rails; a transverse moving cylinder is mounted in the groove-shaped structure, the right end of the transverse moving cylinder is hinged to the right end of the rerailing beam through a first pin shaft, and the left end of the transverse moving cylinder is hinged to the left end of the moving table through a second pin shaft; the bottom ends of two jacking cylinders arranged in a herringbone form are respectively hinged to the moving table through supporting pin shafts; and the piston ends of the two jacking cylinders are symmetrically hinged to positions under a jacking head, so that a triangular stable structure is formed by the moving table, the two jacking cylinder and the jacking head through mutual connection.
