Embodiment Construction

[0029] The present invention adopts the method of multiple sensors to realize the automatic leveling of the construction elevator. This method abandons the encoder, and only uses a plurality of sensors to realize the automatic leveling. There is no need for self-study in debugging, and in application installation, it also avoids the shortcomings of high precision and high environmental requirements for encoder installation.

[0030] Such as figure 2 As shown, it is a schematic diagram of an embodiment of the automatic leveling control system of the construction elevator of the present invention. The system is used to realize the parking of the cage according to the leveling board arranged on the docking floor, and specifically includes a first sensor 21, a second sensor 22, a third sensor 23 and a main control unit 24, wherein the first sensor 21, the second sensor 22 and the third sensor 23 are successively installed at different height positions on the cage 20. The main c...

Abstract

The invention relates to an automatic leveling control system for a construction hoist. The automatic leveling control system is used for stopping a suspension cage according to leveling insertion plates arranged on a stop layer. The automatic leveling control system comprises a first sensor, a second sensor, a third sensor and a main control unit, wherein the first sensor, the second sensor and the third sensor are arranged at different height positions on the suspension cage sequentially; the main control unit is used for determining a target suspension cage stop layer by calculating the number of the leveling insertion plates through which the first sensor, the second sensor and the third sensor pass, reduces the speed of the suspension cage when the first sensor or the third sensor passes through the target stop layer according to a running direction of the suspension cage, and stops the suspension cage when the second sensor reaches the leveling insertion plate of the target stop layer. The invention also provides the corresponding construction hoist. By the invention, the installation complexity is reduced greatly, the use reliability is improved and a self-learning process of equipment is also avoided.

Description

technical field [0001] The invention relates to the field of elevator control, and more specifically, the invention relates to an automatic leveling control system of a construction elevator and a construction elevator. Background technique [0002] Construction hoists are widely used in various infrastructure industries and are one of the most frequently used construction machines for carrying people and goods in construction. The construction hoist is usually used with the tower crane on the construction site, which mainly controls the up and down operation and docking of the cage through the electrical control system. [0003] There are many types of construction elevators. The cage parking of construction elevators is divided into two types according to their control methods, one is manual parking, and the second is automatic parking (also known as automatic leveling). Among them, manual docking means that the specific position where the hoisting cage stops is completel...
