The jacking device for the passage pedal of the boarding bridge is special in that it also includes a guide sleeve, and the guide sleeve is composed of a sleeve body and an annular seat;

The guide sleeve is inserted into the guide hole, the return spring is sleeved on the sleeve body of the guide sleeve, and the guide column is slidingly matched with the sleeve body of the guide sleeve.

The jacking device for the aisle pedal of a boarding bridge is special in that: the electromagnet bracket is composed of a bottom case and an upper cover, and the bottom case and the upper cover are detachably connected;

The electromagnet is fixed on the upper cover, and the guide hole is arranged on the upper cover.

The jacking device for the aisle pedal of the boarding bridge is special in that the bottom case and the upper cover are in the shape of channel steel, and the flanges of the bottom case and the upper cover are connected by bolts.

The jacking device for the pedals of the aisle of the boarding bridge is special in that it also includes springs acting together for balance;

The spring is arranged at both ends of the electromagnet support, and the spring contacts and cooperates with the bottom surface of the pedal.

The utility model relates to a jacking device for a boarding bridge channel pedal, the pedal is hinged with one channel, and is movably matched with the other end; the electromagnet bracket is fixedly connected with the channel hinged with the pedal, and the head of the adjusting screw cooperates with the pedal; boarding When the aircraft is bridged or retracted, the electromagnet is energized, and the armature moves upwards, and the adjusting screw lifts the pedal, so as to prevent the pedal from causing damage to the passage when two adjacent passages move relative to each other. After docking the aircraft, the electromagnet loses power, the armature resets, and the pedal descends thereupon.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, Figure 2, and Figure 3, a jacking device for boarding bridge channel pedals, which includes an electromagnet bracket 1, an electromagnet 2, an armature 3, a return spring 4, a guide column 5 and an adjustment screw 6 ,

The electromagnet 2 is fixedly connected with the electromagnet bracket 1, the armature 3 is arranged under the electromagnet 2, the lower end of the guide column 5 is fixedly connected with the armature 3, the return spring 4 is arranged on the guide column 5, and the return spring 4 is located on the electromagnet Between the bracket 1 and the armature 3; the guide column 5 slides with the guide hole on the electromagnet bracket 1, the adjustment screw 6 is screwed with the upper end of the guide column 5, and the head of the adjustment screw 6 cooperates with the pedal support.

As a further improvement of the utility model: it also includes a guide sleeve 7, the guide sleeve 7 is composed of a sleeve body 71 and an annular seat 72;

The guide sleeve 7 is inserted into the guide hole, the return spring 4 is set on the sleeve body 71 of the guide sleeve 7, and the guide post 5 is slidingly matched with the sleeve body 71 of the guide sleeve 7,

The electromagnet bracket 1 is composed of a bottom case 11 and an upper cover 12, and the bottom case 11 and the upper cover 12 are detachably connected;

The electromagnet 2 is fixed on the upper cover 12, and the guide hole is arranged on the upper cover 12.

The bottom case 11 and the upper cover 12 are in the shape of channel steel, and the flanges of the bottom case 11 and the upper cover 12 are connected with bolts.

As a further improvement of the present utility model: as shown in Figure 4, also comprise the spring 13 of balancing action together; The bottom surface of the pedal 10 is engaged in contact.
