Description

An anti-collision pedal mechanism and pedal anti-collision system for a corridor elevator

technical field

The invention relates to the technical field of corridor elevators, in particular to an anti-collision pedal mechanism and a pedal anti-collision system for a corridor elevator.

Background technique

The elevators used in the society are mainly box-type elevators that go up and down vertically and escalators that go up or down continuously along the slope. These two types of elevators are impractical because they take up a large building area and space, and the cost is high, so a corridor elevator installed on the corridor has been designed. However, if the corridor is not cleaned up or objects are left, there will be safety hazards when the pedals take people up or down. The utility model patent 201020250702.2 discloses a folding pedal mechanism for a stairway elevator, which uses a plunger arranged at the front or rear end of the pedal, a slide rod connecting the plunger and the pedal, and a travel switch to detect obstacles in front of or behind the pedal. The pedal stops when an obstacle is encountered. Although the folding pedal mechanism can detect obstacles, it can only detect obstacles in front of or behind the pedals, without considering the possibility of obstacles on the sides of the pedals, and the anti-collision protection is not comprehensive. Simultaneously, this folding pedal mechanism utilizes components such as a striker bar and a slide bar to increase the weight of the whole pedal, plus the weight of the bearer, so that the requirements for the pedal limit and flip structure are higher, and the production and maintenance costs are increased.

detailed description

As shown in Fig. 1, an anti-collision pedal mechanism for a corridor elevator includes a pedal 1, a connecting part 2 and an anti-collision device. The pedal 1 is connected with the moving frame running up and down the corridor in the corridor elevator through the connecting part 2, and the pedal 1 moves together with the moving frame. Wherein the connecting part 2 includes a connecting rod and a turning mechanism, the pedal 1 is connected to the moving frame through the connecting rod and the turning mechanism in turn, and the pedal 1 can be limited and turned over by the connecting part 2 .

The pedal 1 includes an upper cover 11 , a pedal body 12 , and a lower cover 13 arranged sequentially from top to bottom. One side of the pedal body 12 is connected with the connecting part 2, and the front, side, and rear faces of the pedal body 12 are provided with recesses. The pedal body periphery forms a continuous recess that is not closed at the truncation point. The recess is used to place a hydraulic sensing component, such as the anti-collision hydraulic pipe 3 , for detecting obstacles in front, rear and side of the pedal.

As shown in Figures 1 and 2 , the anti-collision device includes an anti-collision hydraulic pipe 3 , an anti-collision connection assembly and a micro switch 5 . The anti-collision hydraulic pipe 3 is set in contact with the micro switch 5 through the anti-collision connection assembly. The anti-collision hydraulic pipe 3 is a soft hydraulic pipe with obvious deformation. When the anti-collision hydraulic pipe 3 generates hydraulic pressure due to collision , the anti-collision connection assembly pushes the micro switch 5 under the action of hydraulic pressure, that is, touches the micro switch 5 to act, and connects with the micro switch 5. The corridor elevator control system responds to the obstacle detection signal and controls the mobile frame to stop running to ensure safety. . At this time, the corridor elevator control system and the anti-collision pedal mechanism constitute a pedal anti-collision system for the corridor elevator, and the anti-collision pedal mechanisms mentioned in this article and not limited to this content are all applied to the pedal anti-collision system.

The anti-collision hydraulic pipe 3 is arranged in the recess, which is more convenient to install than being directly arranged around the pedal body 12 without a recess, and also prevents the anti-collision hydraulic pipe 3 from protruding too far from the pedal so that people step on it by mistake when riding. In spite of this, the corridor elevator malfunctions. The anti-collision hydraulic pipe 3 adopts wear-resistant materials, and the anti-collision hydraulic pipe 3 can be equipped with liquids such as oil or water. If the durability of the anti-collision hydraulic pipe 3 is further considered, the anti-collision device can also include protective components. , does not affect the anti-collision hydraulic pipe 3 to sense the protective components exerted by external obstacles, such as rubber film covering the anti-collision hydraulic pipe 3, not only to protect the anti-collision hydraulic pipe 3 from wear, but also to be beautiful and easy to replace and maintain.

For the sake of pedal beauty and anti-collision sensitivity, the anti-collision connection assembly and the micro switch 5 are arranged on the pedal 1, especially designed in the closed space between the pedal body 12 and the lower cover. The anti-collision connection assembly includes a hydraulic joint 41 , a hydraulic joint sleeve 42 , a hydraulic switch piston 43 , a hydraulic switch mounting plate 44 , and a fastener 45 . After the anti-collision hydraulic pipe 3 is arranged around the pedal body 12, one end extends into the closed space, connects one end of the hydraulic switch piston 43 through the hydraulic joint 41, and connects the hydraulic joint sleeve 42 to the closed space. The hydraulic joint 41 is fixed; the micro switch 5 is arranged on the hydraulic switch mounting plate 44, and the other end of the hydraulic switch piston 43 utilizes the fastener 45, such as a bolt and the hydraulic switch mounting plate 44 Connection; the hydraulic switch piston 43 is set in contact with the micro switch 5 . The hydraulic switch piston 43 is facing the micro switch 5, and the hydraulic pressure of the anti-collision hydraulic pipe 3 pushes the hydraulic switch piston 43 to act on the micro switch 5, that is, when the corridor elevator is running, the pedal 1 detects at least the front Or when there is an obstacle behind or on the side, the microswitch is triggered, and the mobile frame stops running, and the joint pedal 1 no longer moves upwards or downwards along the corridor.

In addition, in order to ensure that passengers can stand on the pedal 1 in the safe area, the anti-collision pedal mechanism for the corridor elevator also includes a protective plate 6 arranged on the pedal, which is arranged near the connecting part 2, and the protective plate 6 It includes a fixing part and a blocking part. The fixing part is arranged on the surface of the pedal, that is, the upper cover of the pedal. The blocking part is arranged perpendicular to the upper cover of the pedal. The blocking part is preferably set in a tooth shape.
