Embodiment 1

[0051] Such as image 3 As shown, the embodiment of the present invention provides a new type of fairlead, including a fixed chain link 1, a middle chain link 2, a connecting plate 3, a tail chain link 4, and an angle sensor 5;

[0052] Wherein, there are at least two middle chain links 2, and the number of the connecting plates 3 is the same as that of the middle chain links 2;

[0053] A plurality of the middle chain links 2 and a plurality of the connecting plates 3 intersect each other and are sequentially hinged to form a movable chain link assembly, and the fixed chain link 1 is hingedly connected to the head end of the movable chain link assembly, and the tail chain link 4. The tail end of the movable chain link assembly is hingedly connected to form a new fairlead with a chain structure as a whole; the angle sensor 5 is arranged on the tail chain link 4;

[0054] The novel fairlead is connected to the cable, and the cable is extended along the length direction of the ...

Embodiment 2

[0073] Such as Figure 4 As shown, Embodiment 2 of the present invention also provides a control method for a new type of fairlead, and the control operation is performed based on the new type of fairlead, including the following steps:

[0074] Step S100: the angle sensor measures the swing angle of the cable, and sends the collected swing angle information to the main control system;

[0075] Step S200: The main control system adjusts the speed control of the cable reel according to the swing angle information feedback.

[0076] It should be noted that the above-mentioned control method of the new fairlead mainly involves two major operation steps; step S100 is to use an angle sensor to detect the swing angle of the cable (that is, it is also the swing angle of the new fairlead), and then convert the acquired swing angle The information is sent to the main control system; in step S200, the main control system receives the swing angle information in real time, and according ...

Abstract

The invention relates to a novel cable guide frame and a control method thereof. The novel cable guide frame comprises a fixed chain link, a plurality of middle chain links, a plurality of connectingplates, a tail chain link and an angle sensor; the middle chain links and the connecting plates are intersected with one another and are sequentially connected in a hinged manner to form a movable chain link assembly, the fixed chain link is hinged to the head end of the movable chain link assembly, and the tail chain link is hinged to the tail end of the movable chain link assembly, and thus thenovel cable guide frame with a chain structure is integrally formed finally; the angle sensor measures the swinging angle of a cable and transmits acquired swinging angle information to a master control system; and the master control system adjusts control on the rotation speed of a cable reel according to feedback of the swinging angle information. According to the novel cable guide frame and thecontrol method thereof, the angle sensor is used for detecting and feeding back the tensioning state of the cable in real time, and reference is provided for the master control system to control therotation speed of the cable reel; by the detection feedback adjusting mode, the detection precision is high, the feedback adjusting mode is reliable, and the adjusting effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of fairlead control, in particular to a novel fairlead and a control method for the novel fairlead. Background technique [0002] At present, in ports, shipbuilding, petrochemical, electric power and other industries, cable reels and fairleads are widely used. Generally, fairleads are fixed on a certain structure, so that the cables can be retracted and released regularly, so as not to be rolled bad, and at the same time, it can also implement over-tension protection for the cable. [0003] In the prior art, there are still some technical defects in the traditional fairleads for cable reels. For example: Patent CN201220421247 discloses a swing-type cable guide. The cable guide includes a front fixed panel and a rear fixed panel. A roller set, a control switch for controlling the direction of cable transmission, and a tension adjustment mechanism for cable tension control. The structural form of the above-...
