Box type street-crossing escalator

Abstract

The invention relates to a box type street-crossing escalator. The box type street-crossing escalator comprises a guide rail mechanism and a box. The guide rail mechanism is installed under a road and provided with guide grooves. The box can move along the guide grooves. The box type street-crossing escalator further comprises a cam mechanism. The guide grooves extent along U shapes. Rolling wheels are arranged and placed in the guide grooves and can roll back and forth along the guide grooves. The guide rail mechanism is provided with a position detection mechanism and a locking mechanism which are located at the two ends of the upper portion of the box. When the position detection mechanism detects that the box moves to the end of the guide rail mechanism, the rolling wheels are locked by the locking mechanism. The middle portion of the guide rail mechanism is hinged to a base. The cam mechanism comprises a motor, a left cam and a right cam. The left cam and the right cam are arranged on the left side and the right side of a base correspondingly, and the phase difference between the left cam and the right cam is 180 degrees. The motor drives the left cam and the right cam to rotate synchronously. The left cam and the right cam support the guide rail mechanism and make the guide rail mechanism rotate around the base. According to the box type street-crossing escalator, energy is greatly saved, people can cross the road conveniently, operation is safe, and maintenance is easy.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a box-type walking elevator for crossing streets. Background technique [0002] In order to completely separate the pedestrians crossing the road from the vehicles on the road and ensure the smooth flow of traffic and the safety of pedestrians, a large number of pedestrian overpasses or tunnels are built in every city. However, due to the fact that the existing pedestrian overpasses or tunnels all rely on walking, especially through the process of going up and down the stairs, the pedestrians have paid extra physical strength. Pedestrians riding bicycles and others bring traffic difficulties, causing some people to give up passing pedestrian overpasses or tunnels and choose to jaywalk, bringing traffic hazards. Even if the two ends of some pedestrian bridges or cross-street tunnels are respectively equipped with up and down elevators, they are still out of service for a long time due to...

However, due to the fact that the existing pedestrian overpasses or tunnels all rely on walking, especially through the process of going up and down the stairs, the pedestrians have paid extra physical strength. Pedestrians on bicycles bring traffic difficulties, causing some people to give up pedestrian overpasses or tunnels and choose to jaywalk, bringing traffic hazards

Even if there are up and down elevators installed at both ends of some pedestrian bridges or cross-street tunnels, they have been out of service for a long time due to factors such as high installation costs, large power consumption, and high maintenance costs.
