Abstract

PURPOSE:To safely work and easily get out at emergent refuge by constituting a receiving room on the floor receiving frame under the cage of an elevator, out of pillars, a floor, and a temporary enclosure, receiving a control device for operation of the elevator in the room, and providing a buffer striker on the under frame beneath the cage. CONSTITUTION:An inspection cover 7 is provided on the cage floor 6 of an elevator cage to construct an entrance. Pillars 9 are provided on the circumference of a floor receiving frame 8 fitted to the cage floor 6 through vibration-proof rubber and the like, and a floor 10 is fitted on the extreme ends of the pillars 9. An receiving room 11 is constructed by covering the pillars 9 with wire netting and the like, the size is constituted to have enough height to allow work such as adjustment and inspection in the room, and a lamp 12 is fitted. When the inspection cover 7 is opened and a safety switch 13 is put off, the elevator is constituted to be inspected, and a control device 16 and electric equipments are received and arranged in the receiving room 11. A buffer striker 15 is fitted on the under frame 14 of the floor receiving frame 8, when the cage descends and collides with a buffer, the buffer striker transmits the reaction to the under frame 14, to absorb the force to prevent breakage of the receiving room 11.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) TECHNICAL FIELD The present invention relates to storage of equipment mounted on an elevator car.

(Prior Art) A conventional method for storing equipment mounted in an elevator car will be described with reference to FIG. 2.

Generally, the control equipment for the car/beta installed in the car is installed above the car ceiling.

Electrical devices such as a terminal box 1 for wiring, a door control box 2, a computer 3, a door safety detection amplifier 4, and a power supply device 5 are placed on the top of the car ceiling without gaps, and cables connecting the devices are stretched around the car. ing.

Moreover, there are cases in which the above-mentioned equipment cannot be accommodated in the upper part of the car ceiling, and is installed by building a frame on the upper part of the car and stacking them in two layers.

(Problem to be solved by the invention) As mentioned above, all the equipment installed in the elevator is installed at the top of the car, so when adjusting or maintaining the elevator, workers have to climb up on top of the car and use difficult footing. This is a highly dangerous job that involves walking across narrow spaces, and there is a risk of falling into the hoistway or hitting the ceiling of the hoistway.

Furthermore, when an accident occurs and passengers must escape from the car ceiling, the presence of such equipment makes it difficult and dangerous to do so.

In view of the above, the present invention aims to improve safety by enabling a worker to carry out maintenance and inspection work without getting on the car. ) In order to achieve the above object, the present invention provides a storage room under the floor of the elevator car.

A storage room is constructed of pillars, floors, and board fences in the floor support frame under the car, and the control equipment for elevator operation is stored in the storage room.

Also, attach a buffer striker to the bottom frame of the car.

(Function) With the above configuration, maintenance and inspection can be performed safely inside the storage room. In addition, since the number of equipment mounted on the top of the car is reduced, it becomes easier to escape in the event of an emergency evacuation.

(Example) The present invention will be explained with reference to an embodiment shown in FIG.

An inspection door 7 is provided on the car floor 6 of the elevator car to form an entrance/exit. Pillars 9 are provided around the four circumferences of a floor support frame 8 that is attached to the car floor 6 via vibration-proof rubber, etc., and a floor 10 is attached to the tip of the column 9. A storage room 11 is constructed by surrounding the pillar 9 with a wire mesh or a board with a shutter window. The size of the storage room 11 is configured to a height that allows a space for a worker to carry out work such as adjustment and inspection inside the room, and an electric light 12 is attached. A safety switch 13 is provided at the inspection station 7.

Further, a buffer striker 15 is attached to the lower frame 14 of the floor support frame 8.

The control device 16 and electrical equipment, which were conventionally installed above the car ceiling, are housed in the storage room 11 under the floor.

When the inspection cover 7 is opened and the safety switch 13 is turned off, the elevator enters the "inspection" state. Workers can enter the storage room, turn on the lights, and safely begin adjustment and inspection work.

When the car descends and collides with the buffer, the buffer striker] 5 transmits the reaction force to the lower frame 14, and the lower frame 14 absorbs it, preventing damage to the storage chamber 11.

In addition, since the storage room 11 is an area that cannot be easily accessed by the general public, there is no need to store the control device and terminal box in a metal box according to the extension regulations, and the equipment can be made lighter and more integrated, which is rational. You can create a layout.

〔Effect of the invention〕

As described above, the present invention allows for safe and easy adjustment and inspection by relocating equipment such as elevator operation control equipment from the car ceiling to the storage room below the floor, and also reduces the amount of equipment loaded on the top of the car, saving space. By expanding the elevator, it becomes easier to escape in case of emergency evacuation, making the elevator safer.
