Embodiment Construction

[0069] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0070] Such as Figure 1 to Figure 3 Shown, is the double hook driving structure of the present invention; Figure 4 with Figure 5 It is the synchronous lifting control program structure of double-hook driving master and slave hooks of the present invention.

[0071] For the commonly used double-hook gantry crane specially used for H-shaped steel grinding, since there is no automatic leveling function, its double hooks are prone to out-of-sync problems during long-distance lifting.

[0072] In order to realize the synchronous lifting of the special double hooks for H-beam grinding, it is necessary to install a lifting position det...

Abstract

The invention discloses a control method for synchronous lifting of lifting hooks of a double-lifting hook crane. The control procedure of the control method comprises the steps that a master-slave lifting hook lifting speed given control unit of the double-lifting hook crane is formed by functional blocks HSTC01-HSTC14; a master lifting unit single-action lifting control unit of the double-lifting hook crane is formed by functional blocks HSTC15-HSTC19, HSTC28-HSTC31, HSTC38 and HSTC44-HSTC47; a master lifting hook linkage lifting control unit of the double-lifting hook crane is formed by functional blocks HSTC20-HSTC38 and HSTC44-HSTC47; and a master-slave lifting hook fault detecting unit of the double-lifting hook crane is formed by functional blocks HSTC39-HSTC43. According to the technical scheme, synchronous lifting of the double lifting hooks special for H-type steel coping is achieved, even though hoisting loads or self-braking tightness degrees of two lifting hook lifting motors are not consistent, and synchronous lifting of the two lifting hooks of the crane can be achieved.

Description

technical field [0001] The invention belongs to the technical field of electrical transmission control of mechanical equipment. More specifically, the present invention relates to a control method for synchronous lifting of double-hook driving hooks. Background technique [0002] For the H-beam production line, in the production process, due to various reasons, a certain amount of H-beam finished products whose surface needs to be ground off-line will often be produced. For this reason, the H-beam production line is usually equipped with 1 to 2 sets of H-beam grinding special double Hook gantry crane. [0003] This double-hook gantry crane is usually mainly composed of a cart and two electric hoists with the same structure installed on the main beam guide rail of the cart. [0004] The structure of the commonly used double-hook gantry crane for H-shaped steel grinding is as follows: figure 1 shown. [0005] For this commonly used double-hook gantry crane specially used f...
