The invention discloses a medium and low speed maglev traffic engineering low line curve rail bearing beam structure comprising a rail bearing beam, a sleeper pedestal fixed to the top of the rail bearing beam, a rail section fixed to the top of the sleeper pedestal, a reinforcement concrete base plate fixed to the interarea of the horizontal ground and guide rails arranged on two sides of the rail bearing beam; the top surface of the reinforcement concrete base plate is arranged obliquely corresponding to the level, the included angle between the top surface of the reinforcement concrete base plate and the level is alpha q, the bottom of the rail bearing beam is fixedly connected to the top of the reinforcement concrete base plate, the axle of the rail bearing beam, sleeper pedestal and rail section are perpendicular to the top surface of the reinforcement concrete base plate, the included angle between the central line of the rail section and the central line of the line is alpha, and alpha 1 = alpha. By the aid of the structure, the installation requirements for a maglev vehicle contacting with the rail can be met, the construction difficulty of soil engineering base below the rail bearing beam is not raised, and the long-term stability is not reduced.

The invention discloses a multi-mode English teaching device for English teaching and relates to the technical field of teaching devices. A limiting mechanism is fixed to a lower side wall of the base, a pressing rod in the limiting mechanism is arranged on the upper side of the base in a suspended mode, sliding grooves are formed in the left side and the right side of a first blackboard and matched with first sliding blocks in a sliding mode, the first sliding blocks are fixed to the left side wall and the right side wall of a second blackboard, the second blackboard is inserted into a collecting box, and a fixing plate is arranged on the front side of the second blackboard in a suspended mode; a second sliding block is fixed to the center of a lower surface of the fixing plate, sliding plates are clamped to the front side and the rear side of the second sliding block, lower side walls of vertical plates of the sliding plates are fixed to an upper side wall of the first fixing plate, limiting blocks are fixed to one sides of inner walls of the sliding plates, positioning rods abut against the other sides of the second sliding block, and is exposed on the front side of the sliding plate at the front side after passing through the vertical plate of the sliding plate at the front side; and after the device is pushed to a classroom where the device needs to be used, the device can be rapidly limited, the time is saved, projection equipment can be installed, and the device is convenient to use.

A multimodal English teaching device used for English teaching, the invention relates to the technical field of teaching devices; There are chutes on the left and right sides of the blackboard. The chutes cooperate with the No. 1 slider. The No. 1 slider is fixed on the left and right side walls of the No. 2 blackboard. The No. 2 blackboard is inserted inside the collection box. The front side of the blackboard is suspended with a fixing plate, the center of the lower surface of the fixing plate is fixed with the second sliding block, the front and rear sides of the second sliding block are clamped with sliding plates, and the lower side wall of the vertical plate of the sliding plate is fixed on the first fixed On the upper side wall of the board, one side of the inner wall of the slide plate is fixed with a limit block, and the other side of the No. 2 slider is in contact with a positioning rod. The front side of the device; after the device is pushed to the classroom to be used, the device can be quickly limited to save time, and the projection equipment can also be installed, which is convenient to use.
