JPH0618566U - Self-propelled garter with a middle pillar that shares the load on the second floor - Google Patents

Abstract

(57) [Summary] [Purpose] The present invention is extremely lightweight even with a long span crane garter to be installed in a two-story parking lot, etc., it reduces running power, and many cutouts are not created in the second floor space above ground site. The purpose is to be able to use the same space for parking all. [Structure] Rolling wheels at the lower ends of the self-propelled frames on both sides are mounted on track rails on both sides of the site, and several beam frames are bridged between the pair of self-propelled frames at the height of the ceiling on the second floor. In addition, the structure is such that the center pillar, which supports the rolling wheels in contact with the second floor at the lower end, is drooped.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lightweight and long-span crane garter.

[0002]

[Prior art]

 A crane garter that hoists and traverses a gondola, etc., consists of traveling frames at both ends that automatically travel and a beam frame that bridges between them.Because the beam frame is a heavy load, the conventional span is limited to a short span. It was being done.

[0003]

[Problems to be solved by the device]

 Since the conventional self-propelled crane garter is considerably heavy when the span is made large, it is necessary to construct intermediate legs that travel in the same plane as the traveling frame at several intermediate positions, which further increases the weight. Therefore, a large amount of power is required for running.

Further, for example, when a vehicle, a container, or the like is lifted and arranged on an upper floor having a second floor, the blow-through portion for the lower end traveling portion of the intermediate leg to reach the ground must be cut out in the upper floor. Therefore, there was a defect that the upper floors could not be used to fill the site.

The present invention provides a self-propelled crane garter, which is extremely lightweight and has a very large span, so that the upper floor of the floor can be effectively used to fill the entire site without cutting out the floor of the second floor. The purpose is.

[0006]

[Means for Solving the Problems]

 Rolling wheels at the bottom of the self-propelled frame are mounted on track rails installed on both side edges of the site, and a pair of self-propelled frames are bridged to the height of the second floor between the pair of self-propelled frames. The structure will be such that the center pillar that supports the rolling wheels in contact with the floor is suspended.

[0007]

[Action]

 The present invention is a self-propelled garter that has a beam frame configured on the ceiling of the second floor with a center pillar hanging from the lower end of the wheel that contacts the second floor, and the span between the self-propelled frames on both sides is long. Even if it is constructed, the weight of the beam frame hangs down, and several middle pillars whose lower ends are in contact with the second floor are supported by being shared by the second floor, so the overall weight is extremely light and the movement of the garter is stable. Since it does not require an intermediate leg to reach the ground, it does not require any cutout part on the second floor except for the unloading pit for one vehicle, for example, and the second floor has the same area as the space above the ground and fills the site. Space available.

[0008]

【Example】

 The present invention is, for example, a crane garter used for a two-story parking lot having a large site area as shown in FIG. A beam frame 4 is bridged at the height of the ceiling on the second floor between the self-propelled frames 3 and 3 on which the wheels 2 and 2 are mounted. It has a structure in which a central pillar 6 to which 5 is pivoted is formed to hang down. Therefore, even if the span of the self-propelled frame becomes large and the weight becomes heavier, the center column that moves along with the self-propelling will share and support the load, resulting in a lighter overall weight and less traveling power.

Therefore, the girder frame is equipped with a pallet lift for one vehicle and a gondola 8 for traversing freely, and by opening an unloading pit for one vehicle on the second floor, the second floor is above ground. The same space as the site area can be used as a parking space for cars.

[0010]

[Effect of device]

 According to the present invention, the crane garter for storing cars and containers on the second floor is made extremely lightweight to enable stable traveling movement with a small amount of power, and since the cutout portion is not required on the second floor, the space on the second floor is the ground floor area. There is an effect that all can be used in almost the same area.
