[0023] A construction elevator with a pedal, such as Figs. 1-3As shown, the construction elevator includes a tower 1 located outside the building, an elevator body 2 mounted on the tower 1, a drive unit for driving the elevator body 2 to move up and down along the tower 1, and a control system for controlling the operation of various electrical components in the construction elevator. The elevator body 2 has a doorway at its front end (facing the building), with elevator doors 21 hinged to both sides of the doorway for closing the doorway and for rotating towards the building. The elevator doors 21 are also connected to the elevator body 2 via an automatic door closer 211. The elevator body 2 has a protruding operator's cab 3 on the side away from the tower 1. The interior space of the operator's cab 3 is connected to the interior space of the elevator body 2, and an isolation door is installed at the connection point. An observation window 31 is provided on the outer wall of the operator's cab 3. Below the elevator body 2 are rails 4, pedals 5, a drive assembly 6, a position detector 7, and a distance detector 8. The rails 4 are fixedly installed on both sides of the lower surface of the base plate 22 of the elevator body 2. The pedals 5 are located below the front end of the base plate 22, with the rails 4 movably connected to both sides of the pedals 5. The drive assembly 6 is connected to the pedals 5 and drives the pedals 5 to move forward along the rails 4. Position detector 7 and distance detector 8 are both located below pedal 5 and at the front end of elevator body 2. Position detector 7 is a position sensor (such as a proximity switch) used to detect whether the elevator's lifting height has reached the target height of the building floor, where a corresponding sensing marker is located. Distance detector 8 is a distance sensor used to detect the gap between the construction elevator and the building floor after the elevator reaches the target position. The control system is connected to automatic door closer 211, drive assembly 6, position detector 7, and distance detector 8, respectively. It receives information from position detector 7 and distance detector 8, analyzes and processes it, and sends commands to enable automatic door closer 211 to open and close the door, drive the construction elevator to lift and lower, and drive assembly 6 to extend and retract pedal 5. The connections, functions, and principles of position detector 7, distance detector 8, and other electronic and electrical components with the control system are standard in the field of automation control and will not be described in detail here.

The position and distance detectors detect when the elevator has reached its destination and the width of the gap between the elevator front and the building. The drive assembly then extends the pedals a certain length, allowing them to rest against the building's floor slab. After the elevator door opens, safety barriers are formed on both sides of the pedals. This invention is convenient to use, has good safety performance, and achieves automated pedal control.

[0025] As preferred, the track 4 is formed by channel steel processing, the notches of the two tracks 4 are opposite, the inner surface of the lower wing plate of the track 4 is provided with a plurality of rollers 41, the both sides of the pedal 5 are inserted into the grooves of the channel steel, and the bottom surfaces of the both sides are correspondingly attached to the rollers 41 in the two tracks 4. The elevator body 2 is provided with a plurality of connecting plates 9 below and along the length direction, the connecting plates 9 are correspondingly welded and connected to the lower wing plates of the two tracks 4 at both ends, and at least one connecting plate 9 is connected to the front ends of the two tracks 4. The position detector 7 and the distance detector 8 are both fixedly installed on the upper surface of the connecting plate 9 at the front end. The pedal 5 is a steel plate, and the upper surface is provided with anti-skid lines. The middle part of the rear end of the pedal 5 is provided with a downward bending part 51, the driving assembly 6 is fixedly installed on the bottom plate 22 or the connecting plate 9 behind the pedal 5, the driving assembly 6 is a motor screw assembly or a cylinder assembly, and the driving end of the driving assembly 6 is connected to the bending part 51. The specific structure and transmission connection mode of the driving assembly 6 are common in automation equipment, and are not described in detail in the utility model.

[0026] The utility model discloses a track formed by channel steel processing, and the rollers are installed on the lower wing plate of the track, so that the rollers can make the pedal move more smoothly forward and backward in the process of driving the pedal to move forward and backward by the driving assembly.
