the tail end of the lengthening pipe is closed, at least six through holes are formed in the pipe wall of the lengthening pipe, and the through holes are uniformly distributed on the front side, the rear side and the lower side of the lengthening pipe.
If the length of the car sill is large, dust and sundries in the middle of the car sill groove are difficult to clean by blowing, and the air flow is extended to the middle of the car sill groove through the extension pipe, so that the dust and sundries are prevented from being accumulated in the middle of the car sill groove.
The length of the lengthened pipe is less than half of the length of the elevator car sill groove;
the inner diameter of the lengthened pipe is 4-6 mm, and the thickness of the pipe wall of the lengthened pipe is 1-2 mm.
At least two brackets for supporting the lengthening pipe are arranged in the elevator car floor waistcoat groove;
the support is Y-shaped and comprises support rods positioned in the vertical direction, two branch support rods are connected above the support rods, and the two branch support rods form a clamping groove for clamping the lengthened pipe.
Set up the fixed extension pipe of support in the car sill, avoid extension pipe to drop because of frequent damage of rocking when the elevator goes up and down.
The elevator also comprises a landing sill positioned in front of the car sill when the elevator stops at a floor, and a landing sill groove is formed in the top surface of the landing sill;
as another preferable scheme, a second air blowing opening is further arranged on the air blowing pipe, and the second air blowing opening is aligned to the landing sill groove.
When the elevator stops at a floor, the elevator car sill groove and the landing door sill groove can be cleaned simultaneously, the landing door is prevented from being blocked by garbage in the landing door sill and being opened and closed, extra cost is saved, and time and labor are saved.
The aperture of the first air blowing port and the aperture of the second air blowing port are 2-4 mm;
the aperture of the first air blowing opening is at least 1mm smaller than that of the second air blowing opening.
The aperture for two gas blowing openings is the same, and the aperture of the first gas blowing opening is smaller, so that the gas pressure at the second gas blowing opening is larger, the flow rate of the blown gas is faster, and the better cleaning effect is achieved.
