[0002] With the deepening of reform and opening up, the rapid development of China's economy, and the rapid increase in urban car capacity, the construction of parking lots has to expand underground and in the air. Domestic fully automatic flat mobile stereo garages are gradually becoming popular. Flat mobile garages use elevators to transport vehicles to designated parking floors or entrance and exit floors. Stereo garage elevators have the characteristics of heavy loads, more than 7 tons, and high speed, so the elevator running track has high-precision requirements, especially on-site welding of track joints and flatness are particularly critical to prevent safety problems when the elevator is running vertically at high speed.

[0003] Existing elevator tracks are mostly T-shaped steel. However, for intelligent stereo garages, the elevator tracks need to be redesigned based on their service life and safety considerations, which requires ensuring the accuracy of track installation and welding.

[0004] In order to reduce garage costs, improve land utilization and take the construction location of the garage into comprehensive consideration, the fully automatic flat mobile multi-story parking garage is generally built with 6 floors or more (above ground or underground). It is difficult to achieve mechanical processing, product transportation and equipment installation of a single track, so the track is cut into several sections (each section is 5.5 meters to 7 meters) to facilitate processing, transportation and on-site material stacking. During installation, the upper and lower tracks will be butt-jointed. In order to ensure the accuracy of the upper and lower tracks after installation and the reliable welding of the butt gap with minimal deformation, this butt welding fixture was invented.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The position of the upper and lower docking rails is adjusted by tightening the bolts to ensure that the verticality of the rail joints remains consistent from top to bottom and from left to right. In addition, the rails are prevented from being misaligned during welding and deformation of the rail docking welds is prevented.

[0021] Figure 1 , Figure 2 In the figure, the fixing device for butt welding of vertical tracks of a flat mobile stereo garage includes an adjustment locking plate 1, a connecting plate 2, a track adjustment plate 3, a reinforcement plate 4 and a threaded connecting plate 5. Among them, the connecting plate 2 is a metal flat plate with trapezoidal grooves symmetrically opened on both sides, one end is a plane, and the other end has a through groove opened along the center line direction. The inner wall of the through groove is symmetrically cut into inclined planes, and its cross section is an isosceles trapezoid. The ends of the connecting plate 2 on both sides of the through groove are fixedly connected to the track adjustment plate 3 through the threaded connecting plate 5, and the other end of the connecting plate 2 is fixedly connected to the adjustment locking plate 1. The track adjustment plate 3 and the threaded connecting plate 5 are both rectangular blocks made of metal. The track adjustment plate 3 is welded and assembled with the threaded connecting plate 5, and the threaded connecting plate 5 is assembled and fixed on the connecting plate 2 through a high-strength screw. Two M20 adjustment locking threaded holes are symmetrically reserved on the track adjustment plate 3, and the hole direction of the adjustment locking threaded holes is perpendicular to the connecting plate 2. The adjusting locking plate 1 is a rectangular block, welded and assembled on the connecting plate 2. Four M20 adjusting locking threaded holes are reserved side by side and symmetrically on the adjusting locking plate 1, and the holes are parallel to the connecting plate 2. Two M20 adjusting locking threaded holes are reserved symmetrically on the connecting plate 2 near the adjusting locking plate 1, and the holes are perpendicular to the connecting plate 2. The reinforcing plate 4 is welded and fixed between the connecting plate 2 and the threaded connecting plate 5. The ends of the threaded connecting plate 5 and the track adjustment plate 3 near the through groove are both provided with inclined tables, and the inclined tables are coplanar with the inner walls of the adjacent through grooves. The inner side surface of the adjusting locking plate 1 relative to the threaded connecting plate 5 is perpendicular to the connecting plate 2, and the parallelism of the adjusting locking plate 1 and the threaded connecting plate 5 is ±0.01. The connecting plate 2 is parallel to the inner side surface of the relative track adjustment plate 3, and the parallelism of the connecting plate 2 and the relative track adjustment plate 3 is ±0.01.

[0022] The adjustment locking plate 1, the connection plate 2, the track adjustment plate 3, the reinforcement plate 4 and the threaded connection plate 5 are all machined to ensure the flatness, roughness and parallelism of the plane. The adjustment locking plate 1 is welded with the connection plate 2, the connection plate 2 and the threaded connection plate 5 are connected by high-strength hexagon socket bolts and then fixed by welding through the reinforcement plate ④, and the threaded connection plate 5 is fixed by welding with the track adjustment plate 3. After the production is completed, the parallelism of the adjustment locking plate 1 and the threaded connection plate 5 is guaranteed to be within ±0.01, and the parallelism of the connection plate 2 and the track adjustment plate 3 is guaranteed to be within ±0.01. This ensures that it can be put into use with guaranteed quality and quantity.

[0023] The M20 adjustment locking threaded holes on the adjustment locking plate 1, the connecting plate 2 and the track adjustment plate 3 are used to adjust the track.

[0024] The adjustment locking plate 1 is fastened to the track square tube with high-strength screws, the connecting plate 2 is fastened to the track square tube with high-strength screws, and the track adjustment plate 3 is fastened to the running track surface with high-strength screws. By adjusting the screws on the adjustment locking plate 1, the connecting plate 2 and the track adjustment plate 3, the front, back, left, and right positions of the upper and lower tracks can be adjusted and tightened during welding to prevent displacement after welding.

[0025] During welding, the fixed rails are first spot welded, and then continuous welding is achieved at the rail joints through the through-slot gap welding method of the present invention, thereby ensuring quality.
