However, there is no standard for elevators used to transport vehicles in the existing standards. Instead, it refers to the design of freight elevators. The goods in and out of freight elevators are manually carried, and the vehicles are driven by the driver, and the speed and distance are also difficult to grasp, especially for many elevators. novice
[0003] In GB7588, although the strength of hall door is changed to 1000N / 100mm 2 , but the strength of the door is to protect against the collision of people. In actual use, the collision force of the vehicle is much higher than that of people. Once the driver of the vehicle makes a wrong action, it will lead to an extremely serious safety accident.

Embodiment 1
[0046] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a car elevator hall door anti-collision system includes a hall door 1, a blocking device 7 and a linkage device.
[0047] The hall door 1 corresponds to a vehicle access passage, and the blocking device 7 has a blocking state that cuts off the vehicle access passage (such as figure 1 shown), and the opening state of the avoidance vehicle access channel (such as figure 2 shown).
[0048] Such as figure 1 , figure 2 As shown, the blocking device 7 includes: a column 2a, and a railing 3a rotatably mounted on the column 2a and driven by a linkage device. The column 2a is fixedly installed on the ground outside the hall door 1, and the railing 3a has different rotation positions for blocking and avoiding the passage of vehicles. Such as figure 1 As shown, in the blocking state, the railing 3a remains horizontal, and in the open state, the railing 3a remains vertical.
[0049] The railing 3a is 1500-100...
Embodiment 2
[0059] Such as Figure 5 , Figure 6 , Figure 7 As shown, a car elevator hall door anti-collision system includes a hall door 1, a blocking device and a linkage device.
[0060] The blocking device is a railing 3b that lifts vertically, and the railing 3b has the highest position that cuts off the vehicle access passage (such as Figure 5 shown), and the lowest position of the avoidance vehicle entering and exiting the channel (such as Figure 6 , Figure 7 shown).
[0061] Such as Figure 5 As shown, when the hall door 1 is closed, the railing 3b is at the highest position, and when at the highest position, the height of the railing 3b from the ground is equal to half of the hall door opening width. Such as Figure 6 , Figure 7 As shown, when the hall door 1 is fully opened, the railing 3b sinks under the ground (that is, the ground is provided with a groove for accommodating the railing 3b). The railing 3b is 1500-1000mm away from the hall door.

Abstract
The invention discloses a collision avoidance system for a hoistway door of a car elevator. The system comprises a hoistway door and a vehicle access way corresponding to the hoistway door. The systemis also provided with a stopping device and a linking device, wherein the stopping device has a stopping state separating the vehicle access way and an open state avoiding the vehicle access way; andthe linking device links with closing and opening actions of the hoistway door so as to correspondingly drive the stopping device to enter the stopping state and the open state. According to the collision avoidance system for the hoistway door of the car elevator disclosed by the invention, the collision avoidance system and the hoistway door are synchronously opened or closed to prevent a vehicle from directly being collided with the hoistway door of the car elevator, so that the using safety of the car elevator is improved.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a hall door anti-collision system of an automobile elevator. Background technique [0002] With the advancement of China's urbanization process, the number of elevators installed and maintained has grown rapidly, and the number of elevators suitable for transportation vehicles has also begun to increase. However, there is no standard for elevators used to transport vehicles in the existing standards. Instead, they refer to the design of freight elevators. The goods in and out of freight elevators are manually carried, and the vehicles are driven by drivers in the cars. It is difficult to grasp the speed and distance, especially for many elevators. novice. [0003] In GB7588, although the strength of hall door is changed to 1000N / 100mm 2 , but the strength of the door is to protect against the impact of people. In actual use, the impact force of the vehicle is much higher than...
