Problems solved by technology

For example, the Chinese patent application (201810846695.3) uses electromagnets, filling blocks and compression springs to fill the gap. This solution involves electrical components, and it is necessary to ensure the waterproof insulation of the device. If the circuit fails, the filling block may not be retracted.
Another example is the Chinese patent application (201910338375.1), which uses gears and baffles to fill the gap. This scheme has a complicated structure and is not conducive to installation and maintenance.
Another example is the Chinese patent application (201721752655.X), which uses the reel and the moving belt to fill the gap. Although this solution solves the problem of gap filling, the device does not receive the side of the car after recovery, and it may be in the elevator.

Embodiment 1

[0048] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the elevator car and landing side gap protection device includes four fixed sheet metal, A side protection plate 5 and B side protection plate 6;

[0049] The upper part of the car sill 10 is provided with a transverse U-shaped groove with an opening facing forward;

[0050] The fixed sheet metal is divided into rear vertical part, upper horizontal part, front vertical part and lower horizontal part connected in sequence. The upper horizontal part is bent vertically forward from the lower end of the rear vertical part, and the front vertical part is bent vertically downward from the front end of the upper horizontal part. Fold, the lower transverse part is bent vertically backward from the lower end of the front vertical part;

[0051] The rear vertical parts of the first fixed sheet metal 21 and the second fixed sheet metal 22 are fixed on the front side near the A end of the A side car door 1a;

[00...

Embodiment 2

[0068] Based on the elevator car and the landing side gap protection device of Embodiment 1, such as Image 6 , Figure 8 As shown, the movable groove 9 of the protective plate 5 on the A side, its front and rear depth gradually becomes shallower from the A end to the B end;

[0069] The front and rear depths of the movable groove 9 of the protective plate 6 on the B side gradually become shallower from the B end to the A end.

[0070] Preferably, the other end of the connecting rod 3 is pivotally connected to the movable groove 9 through a rivet.

[0071] Preferably, a hole is opened at the upper end of the rear vertical part of the fixed sheet metal for fixing to the car door.

[0072] Preferably, a hole is opened at the rear end of the lower transverse part of the fixed sheet metal for hinged connection rod 3 at one end via hinged bolt 4 .

[0073] Preferably, the length of the connecting rod 3 is 0.8-1.1 of the front-rear depth of the transverse U-shaped groove on the u...

Abstract

The invention discloses an elevator car and landing side gap protective device which is characterized in that two fixed metal plates are mounted at the lower parts of car doors on the left side and the right side respectively; the lower transverse parts of the fixed metal plates extend backwards into a U-shaped groove in the upper part of a car sill; the two ends of connecting rods are rotatably connected with the lower transverse parts of the fixed metal plates and movable grooves of protective plates respectively; a guide bolt is fixedly arranged on the upper side face, close to the A end, of the B-side protective plate; the B-side protective plate is located below the A-side protective plate; and the guide bolt extends into a left-right guide groove in the lower side face of the A-side protective plate. According to the elevator car and landing side gap protective device, the car doors directly drive the fixed metal plates, the connecting rods and the protective plates, and through simple mechanical linkage between the connecting rods and the protective plates, a gap between the car sill and a landing side sill during elevator leveling can be reduced when the car doors are opened, and the protective device retracts into the car sill after closing of the car doors; and the protective device is simple and reliable in structure, easy to install and maintain, low in implementation cost and high in transmission efficiency.

Description

technical field [0001] The invention relates to elevator technology, in particular to a protective device for the gap between an elevator car and a landing side. Background technique [0002] As a special equipment, elevator is widely used to transport passengers and goods between different floors of buildings, which greatly facilitates people's life. Due to the relative motion between the elevator car and the floor, there must be a gap between the car and the landing side. [0003] my country's "Safety Code for Elevator Manufacturing and Installation" clearly requires that the horizontal distance between the car side sill and the landing side sill shall not be greater than 35mm. The horizontal distance between the ridges is mostly about 30mm. Although the requirements of the specification are met, the gap distance is still too large. When the passenger enters and exits the car, the items carried with him, such as keys, mobile phones, etc., may still fall into the shaft fro...
