Embodiment Construction

[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] The invention provides a control device for dynamically pulling out arm pins, such as figure 2 As shown, the device includes: a receiving device 100, configured to receive the forward leaning signal of the cylinder pin of the telescopic oil cylinder and / or the length of the telescopic oil cylinder; and a control device 200, used to receive the forward leaning signal and / or the When the length of the telescopic oil cylinder reaches the length corresponding to the forward leaning position, the arm pin extraction operation is started and the telescopic oil cylinder is controlled to continue extending to extract the arm pin. Using the forward signal or the ...

Abstract

The invention discloses a control method, equipment, a system, and a crane of a dynamic arm pulling pin of a single-cylinder bolt-type telescopic arm. The equipment comprises a receiving device for receiving a forwarding signal of the cylinder pine of a telescopic oil cylinder and/or length of a telescopic oil cylinder, and a control device. The control device starts to pull the arm pin and continues to pull out a telescopic oil cylinder so as to pull out the arm pin after receiving a forwarding signal and/or the length of the telescopic oil cylinder is equal to the corresponding length of a front position. The provided equipment can dynamically pull out an arm pin during the process when an oil cylinder is pulled out, the oil cylinder does not need to be stayed on a predetermined position for the arm pin pulling operation, the electric control is simplified, the continuity of oil cylinder pulling-out improved, thus the work efficiency is improved, and the service life of arm pin is prolonged.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a control method, equipment, system and crane for a dynamic pull-out pin of a single-cylinder pin-type telescopic boom. Background technique [0002] In lifting equipment, such as truck cranes, single-cylinder bolt-type booms are used more and more. Each arm of the single-cylinder bolt-type boom has several arm pin holes, and there is an arm pin at the end of each arm. After the arm pin is locked with the pin hole of the outer arm, the length of the boom can be fixed. [0003] In the prior art, there are two solutions for arm pin insertion and extraction: semi-automatic telescopic technology and one-button automatic telescopic technology. In the semi-automatic telescopic technology, it is necessary to manually input the telescopic signal of the handle, and then automatically perform the plugging and unplugging action, or manually input the plugging and unplugging signal, and...
