Description

The present invention relates to an elevator-type multi-story parking device,
The present invention relates to a lift carriage guide device of a multi-story parking device capable of safely raising and lowering a lifting carriage for transporting an automobile up and down along a predetermined lifting path.

2. Description of the Related Art An elevator-type multi-story parking device has been proposed to efficiently park a large number of vehicles on a small land.

This vehicle is configured by combining an automobile accommodation rack formed by stacking automobile accommodation spaces for accommodating automobiles destined for each vehicle, and an elevator that vertically transports the automobile along the automobile accommodation rack. Therefore, unlike the multi-story parking system of the gondola type, this machine does not serve as both the accommodation mechanism and the transport mechanism of the car, so even if the number of cars accommodated is increased, the mechanical device becomes extremely large. And it can easily realize high parking efficiency comparable to that of a gondola type, and is extremely useful as a parking device for several tens of vehicles.

Note that the elevator carriage is provided with a guide device consisting of front and rear guide masts and a pair of upper and lower guide rollers that roll in contact with the respective guide masts, mainly for restricting the roll during the ascent and descent. (Eg, Japanese Utility Model Laid-Open No. 49-68176). However, the guide mast in this case is a long member having a T-shaped cross section, and the guide rollers are disposed so as to sandwich the projecting portion of the guide mast from the left and right sides at two upper and lower portions, and the lifting and lowering carriage oscillates. To prevent

Problems to be Solved by the Invention According to such a conventional technique, when an extremely uneven load is applied to the left and right at the time of loading and unloading a vehicle, the lifting carriage has a sufficient inclination with respect to the lateral inclination of the lifting carriage. There was a problem that safety could not be ensured. That is, since the pair of upper and lower guide rollers has a small distance between the horizontal axes, only one set at different height positions on both sides of the guide mast only contributes to the prevention of the inclination of the lifting carriage, and one guide roller is provided. If the roller is damaged, the function of preventing the inclination of the lifting carriage is lost, and a large accident that the vehicle slides off the lifting carriage may occur.

Therefore, an object of the present invention is to make the distance between the horizontal axes of the first guide rollers sufficiently large, so that even if one of the first guide rollers is damaged, the function of preventing the inclination of the elevating carriage is lost. It is an object of the present invention to provide a lift carriage guide device of a multi-story parking device that can significantly improve the safety of the lift carriage without any problem.

Means for Solving the Problems In order to achieve the above object, a configuration of the present invention comprises a pair of hanging stands erected at both front and rear ends of a rectangular elevating carriage, and opposed to the front and rear of the elevating carriage. A pair of guide masts, and first and second guide rollers attached to each suspension stand and in contact with both side end surfaces and a front end surface of the guide mast, respectively. The gist of the invention is to dispose a pair of shafts each having a distance larger than 1/3 of a lateral width of the lifting carriage at both upper and lower ends of the suspension stand.

According to the configuration of the present invention, since the pair of upper and lower first guide rollers has a sufficiently large distance between the horizontal axes, in addition to the pair of different height positions on both sides of the guide mast, the first guide roller has the same height. A set of positions can also exhibit the function of preventing the elevation carriage from tilting. That is, the first guide roller can maintain a sufficient function of preventing the inclination of the elevating carriage even if one of the pair of upper and lower upper and lower rollers is damaged. The first guide roller has a sufficiently large distance between the horizontal axes, so that one set at the same height position can be rotated around one of the other sets, that is, in the direction in which the lifting carriage is inclined in the lateral direction. This is because it can sufficiently oppose the rotational moment.

The first guide roller is in contact with both end surfaces of the guide mast and the second guide roller is in contact with the front end surface of the guide mast. The swing in the direction can be regulated, and the device can be moved up and down stably.
