Description

A high-safety escalator step tread structure

technical field

The utility model relates to the technical field of escalators, in particular to a step tread structure of an escalator with high safety.

Background technique

Existing escalator steps are generally cast aluminum parts. As shown in Figure 3, the structure includes a tread, an arc-shaped skirt extending downward from the rear end of the tread, and the end of the skirt connected to the front end of the tread. The brackets on both sides form a stable structure similar to a triangle, and the ladder teeth are generally arranged vertically at equal intervals on the tread.

As shown in Figure 4, when the tread advances to the end of the escalator, a comb-tooth plate will be set at the end of the escalator. After the comb-tooth plate touches the advancing tread, it will passively lift to a certain height and the comb teeth will be inserted into the escalator. In the groove between the ladder teeth, remove the possible sundries hidden in the groove of the ladder teeth, so as to avoid the sundries entering the escalator and causing damage to the transmission structure.

However, in the process of elevator operation, if the elevator operation is abnormal, the front end of the comb plate will collide with the front end of the tread. Because the emergency switch is installed under the comb plate, when the comb plate collides with the front end of the tread, it prevents the steps from triggering the emergency switch, and even causes the steps to crack and break off the track, resulting in serious safety accidents.

Please refer to Fig. 1-2, a high-safety escalator step tread structure of the present invention includes a plurality of vertical ladder teeth 11 arranged in an equidistant order and integrally die-cast on the panel of the tread surface 1. The teeth 11 are far away from each other to form strip-shaped grooves. The bottom surface of the groove between the ladder teeth 11 is set as the tooth groove surface 12. The ends of both ends of the escalator are provided with comb-tooth plates 4. The comb teeth of the comb-tooth plate 4 and Ladder teeth 11 are staggered in sequence, and both ends of the alveolar surface 12 toward the comb-tooth plate 4 are inclined downward to form inclined surfaces 13 .

Further, the included angle between the inclined surface 13 and the plane where the tooth groove surface 12 is located is three degrees.

Further, the length of the inclined surface 13 is 14 to 16 mm.

Further, the inclined surface 13 and the front end surface of the tread surface 1 are connected smoothly.
