Embodiment Construction

[0027] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0028] figure 1 is a schematic structural diagram of a standard section provided by an embodiment of the present invention, such as figure 1 As shown, during the jacking process of the tower crane, the jacking beam 5 is driven up by the oil cylinder 6, so that the hanging shoes and the hanging plate are clamped on the appropriate steps, so as to introduce a new standard section.

[0029] In order to be able to accurately detect whether the tower crane is jacked in place, the monitoring system for jacking in place of the tower crane provided by the embodiment of the present invent...

Abstract

The embodiment of the invention provides a monitoring system used for in-place jacking of a tower crane and the tower crane and belongs to the technical field of crane control. The tower crane comprises hanging shoes, hanging plates and steps. When the tower crane is jacked in place, the hanging shoes are connected with the hanging plates in a clamping manner. The monitoring system comprises distance sensors which are arranged on the hanging shoes / hanging plates and are used for detecting the distances between the distance sensors and the clamping connection positions of the hanging shoes / hanging plates and the steps. By means of the above technical scheme, whether the hanging shoes / or the hanging plates are accurately connected with the steps of standard joints in a clamping manner or notcan be accurately detected, and whether the tower crane is jacked in place or not can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of crane control, in particular to a monitoring system for lifting a tower crane into position and the tower crane. Background technique [0002] Jacking safety is the most important link in the safety of tower cranes (referred to as tower cranes). Whether the hanging boots / hanging plates can be successfully hung into the working position of the standard section of the tower crane before the jacking operation starts is another factor that determines the jacking. basic condition of safety. [0003] In order to avoid safety accidents caused by the fact that the hanging plate / hanging shoe is not accurately engaged with the step of the standard joint, it should be detected whether the hanging shoe and / or the hanging plate are accurately engaged with the step of the standard joint. [0004] The detection method adopted in the prior art is to determine whether the jacking is in place according to the detection re...
