[0003] At present, for the installation of the upper bed cover of the escalator, it is usually directly fixed on the upper surface of the truss by simple bolt connection or welding, and the upper bed cover is usually a flat plate or a straight plate with anti-skid lines, even if the upper The bed cover is loosely connected, and passengers are not easy to find this safety hazard, so it is easy to cause safety accidents. In addition, after the upper bed cover is loose, the escalator is still in motion

The invention discloses a safety escalator based on upper bed cover plate overturning. The safety escalator comprises a truss, an upper bed cover plate, a drive shaft, a driving chain wheel, a drivengear and a motor, wherein the driving chain wheel and the driven gear are arranged on the drive shaft; and the motor is externally connected with a driving gear, and the driving gear and the driven gear are in meshing connection through a transmission gear. The upper bed cover plate is provided with a safety device used for prompt and safety protection. The safety device comprises a mounting part,a plurality of rolling wheels which are arranged on the two side faces of the mounting part and are further distributed in an arc shape, a pair of side beams which are arranged at the two sides of the mounting part, arc-shaped rolling grooves which are formed in the corresponding side beams in a penetrating mode and a position holding mechanism which is used for keeping the position of the upperbed cover plate in the overturning process. Arc-shaped openings of the arc-shaped rolling grooves face upwards. The safety escalator further comprises a disconnecting device which is used for disconnecting the transmission gear from the driving gear and the driven gear when the upper bed cover plate is overturned. The safety escalator is simple in structure and convenient to manufacture, the prompt and safety protection effects can be achieved, transmission is interrupted when the upper bed cover plate is offset, the escalator stops running, and therefore the safety performance is further improved.
Description
technical field [0001] The invention relates to a safety escalator based on the flipping of an upper bed cover. Background technique [0002] The escalator is an important means of transportation, widely used in shopping malls, and the escalator carries a large amount of passengers. Therefore, special attention should be paid to the safety factor of the escalator. [0003] At present, for the installation of the upper bed cover of the escalator, it is usually directly fixed on the upper surface of the truss by simple bolt connection or welding, and the upper bed cover is usually a flat plate or a straight plate with anti-skid lines, even if the upper The bed cover is loosely connected, and passengers are not easy to find this safety hazard, so it is easy to cause safety accidents. In addition, after the upper bed cover is loose, the escalator is still in motion. Contents of the invention [0004] In view of the defects of the prior art, the object of the present invention...
