Problems solved by technology

Its disadvantages are: one, because freight elevators and elevators are mainly used to transport goods, their weight is large, especially when heavy goods are moved in, moved out or pushed, and pushed out of the goods elevator or elevator, it will inevitably cause damage to the goods elevator or elevator. One impact force directly acts on the braking device in the drive control mechanism, which will directly affect the reliability of the braking device in the long run; the other is that since the freight elevator and elevator have no anti-fall device, once the traction wire rope breaks, the consequences are unimaginable

Embodiment 1

[0011] Embodiment 1: with reference to attached Figure 1~3 . As for the anti-fall device of the freight elevator, the connecting rod III4 is made of metal or non-metal material, and its shape can be columnar, rectangular, or angular, that is to say, the shape is not limited. The two ends of connecting rod III4 are respectively hinged with support I6 and support II7, and support I6 and support II7 are made of metal or non-metallic materials, and their shapes can be various. Support I 6 is fixed (welded) on the car, and support II7 is fixed on the upper beam of the car. One end of the two rotating rods 5 is respectively affixed (welded) to the connecting rod III4, and the other end is hinged to one end of the connecting rod I2 and the connecting rod 3. The two rotating rods 5 are made of metal or non-metallic materials, and their shape can be cylindrical. It can also be rectangular or angular, that is to say, the shape is not limited. The other ends of the connecting rod 12 ...

Embodiment 2

[0012] Embodiment 2: On the basis of Embodiment 1, the method for preventing falling of the freight elevator elevator, when the freight elevator door or the elevator door is opened, the pulling rod 11 on the freight elevator door or the elevator door is opened with the door direction, the pulling head of the pulling rod pulls a fork rod in the V-shaped fork 1 and forces the fork rod to drive the connecting rod III4 to rotate, and the connecting rod III drives the two rotating rods 5 to move to both sides, that is, to move outward. The two rotating rods drive the connecting rod I2 and the connecting rod II3 to move to both sides (that is, to move outward), and the connecting rod I2 and the connecting rod II3 drive the two shafts 9 respectively hinged thereto to the two sides (freight elevator, lift car, etc.) outside) stretches out and is respectively positioned in the support holes 13 in the support plate 8 and supports and locates the freight elevator or the elevator, and the ...

Abstract

A locating-in-space apparatus for preventing the falling down of freight elevator or lifter features its anti-falling fork-dual connecting rods mechanism with synchronizing and autocontrol functions. The both ends of a connecting rod C are respectively pivoted to supporters A and B. Two rotary rods have one end fixed to connecting rod C and another end pivoted with connecting rods A and B, whose another ends are pivoted to axles. The fork is fixed to connecting rod C.

Description

Technical field: [0001] The invention relates to a freight elevator, an elevator positioning anti-falling device in the air and an anti-falling method, and belongs to the field of elevator installation guarantee device manufacturing. Background technique: [0002] Existing freight elevator, lifting lift do not have anti-falling device in structural design, completely by the braking device control in its drive control mechanism its stay in the air. Its disadvantages are: one, because freight elevators and elevators are mainly used to transport goods, their weight is large, especially when heavy goods are moved in, moved out or pushed, and pushed out of the goods elevator or elevator, it will inevitably cause damage to the goods elevator or elevator. One impact force directly acts on the braking device in the drive control mechanism, which will directly affect the reliability of the braking device in the long run; the other is that because the freight elevator and elevator hav...
