Calling system of traction type building construction elevator

Abstract

The invention discloses a calling system of a traction type building construction elevator. The system involves a calling device and a prompting device, wherein the calling device is in signal connection with the prompting device; the calling device is used for allowing operating personnel to input calling information and sending the calling information to the prompting device; and the prompting device is used for receiving the calling information transmitted by the calling device and prompting a driver. The calling system has the beneficial effects that the calling system is separately arranged and is used for calling a traction type building construction elevator lifting cage. Firstly, the calling device and the prompting device are in direct signal connection, the circuit arrangement isvery simple, and maintenance and inspection are facilitated. Secondly, the calling device of the scheme sends the information to the prompting device instead of directly controlling the lifting cageto move up and down, and the driver is prompted through the prompting device, so that the higher control right is given to the driver, and the driver can flexibly cope with the complex environment ofthe construction site.

Description

technical field [0001] The invention relates to the field of building construction elevators, in particular to a calling system for a traction type building construction elevator. Background technique [0002] Construction elevator, also known as construction elevator, is a kind of construction machinery that adopts gear, rack meshing method or wire rope lifting method to make the car move vertically or inclined to transport construction personnel, tools, equipment and materials. Other hoisting mechanisms are stable, safe and reliable, do not need another machine room or shaft, and have the advantages of convenient disassembly and assembly and strong handling flexibility. obvious effect. [0003] When the users on different floors need to use the elevator, they will be involved in the corresponding operation of calling the elevator. There are also some corresponding call control schemes in the existing elevators. [0004] For example: a Chinese utility model with publicati...

AI Technical Summary

Problems solved by technology

[0006] The following disadvantages still exist in the middle of this technical solution: firstly, its floor calling device is electrically connected with the automatic floor selection device, because the automatic floor selection device can move up and down with the car, so the above-mentioned scheme will cause the circuit setting of the whole system Very complex and inconvenient for maintenance and inspection

Secondly, building construction elevators usually have to be equipped with a driver. In the existing scheme, the calling device and the automatic layer selection device directly transmit control information, which will reduce the driver's control right, so that it cannot flexibly respond to the complex environment of the construction site. , affecting the safe and efficient operation of the lift
