JPH0544971U - Scaffolding board device for lifting cage - Google Patents

Abstract

(57) [Summary] [Purpose] A scaffolding board used as a work scaffold for the convenience of boarding workers in cages that can move up and down along the vertical racks by engaging the vertical racks and the pin racks on the wall. Is installed so that it can be freely moved in and out of the cage floor plate. [Structure] C-shaped guides 3 on both front and rear edges of the cage floor plate 1
Is fixed, and the scaffolding plate 4 is inserted into and removed from this guide. When storing the scaffolding board, the retaining piece 5 provided on the floor board prevents it from coming off. When it is pulled out, the free end of the stopper 6 pivotally attached to the side surface is set as a hooking portion so that it can be locked to a pin provided on a pillar of the cage.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scaffolding board device attached to a cage of an elevator capable of ascending and descending a wall surface, capable of moving in and out from the floor surface to both sides of the wall surface and in a horizontal direction, and giving a little scaffolding for working to an onboard worker.

[0002]

[Prior Art]

 BACKGROUND ART There is a known elevator that is equipped with a rocket that engages with a pinion and a drive source for the sprocket, which is mounted on a wall surface provided with a vertical rail and a pinion rack, and that can move up and down along the vertical rail. Since the original purpose is to raise and lower a worker who carries some work equipment, the cage bottom plate is limited to a very small area.

However, as an application of the elevator, it is often the case that a simple work is desired to be performed while the elevator is being stopped or is being continued. For example, when excavating a hole for burying power transmission tower legs, the hole diameter often reaches about 3 m and the hole depth is around 30 m. Therefore, as shown in Fig. 4, the carrying B is placed on the upper surface of the hole. The terrain R and the pin rack P are provided eccentrically from the center of the hole, and the cage C is moved up and down. A worker on the cage may be unsafe if the distance between the floorboard and the object is large when unraveling the ropes hanging in the central space or when it is necessary to transfer to another device near the ascending / descending space. The accompanying exercise will be forced. If the floorboard is given a sufficient area, there will be a conflict with other members protruding laterally in the lifting space. It was desired that the area of the bottom plate be kept to a minimum and that the area be expanded if necessary.

[0004]

[Means for solving the problem]

 If necessary, the cage floorboards will be provided with scaffolding boards that can be easily pulled out to the side and re-stored.

[0005]

[Embodiment] Taking an example of a buried hole construction for a steel tower leg, FIG. 4 will be described again. A ladder-shaped body composed of a vertical rail R and a pin rack P is vertically fixed to the cross beam B fixed to the upper surface of the hole. The cage C has a floor plate 1 and a back plate 2 and is L-shaped. The cage C is equipped with a sprocket (not shown) and a motor. The cage C moves up and down while holding rails by engaging the sprocket and the pin rack P. As shown in FIGS. 1 and 2, a scaffolding device attached to this cage is composed of a U-shaped guide 3 fixed to the left and right ends of the bottom plate 1 oppositely to each other, and a scaffolding plate 4 movably supported in the guide. Rollers 4a are provided on the scaffolding plate for smooth access. The scaffolding plate 4 and the guides 3 are of equal length, and the scaffolding plate 4 is used for scaffolding by pulling out a little less than half. Retaining pieces 5 are pivotally suspended from the left and right ends of the bottom plate to prevent the scaffolding plate 4 from coming off during storage. A stopper 6 is attached to the scaffolding plate 4 as shown in FIG.

The stopper 6 has a long hole 6a at one end and a hook portion 6b at the other end. The long hole 6a is pivotally attached to the side surface of the scaffolding plate by a shaft 4b. Locking pins 7 are fixed to the pillars of the cage corresponding to the hook portions 6b. When the stopper 6 is pulled out to the full length of the long hole, the hook portion 6b can be engaged with the pin 7. Since the worker moves in the direction of the wall of the hole from the cage or moves out of the frame due to the position of the object, the scaffold plate pulled out always tries to be pulled back to the storage side. Therefore, there is no danger that the hook portion 6b and the pin 7 will be disengaged.

[0007]

【effect】

 In the middle of the hoistway of the cage, if necessary, the stopper piece on one side is released, the scaffold plate is pulled out, and the stopper 6 is engaged with the pin 7. The scaffolding board can be pulled out in both left and right directions. The operator can easily move from the cage to the left and right and move on the floor board, and can safely perform the work on the way up and down. It is released from the cramped floor board and can operate safely on the scaffold board.
