In the embodiment of the present invention, the base 54 is made of angle steel, and is mounted on the trailer frame 1, and the central shaft 541 is made of high-strength steel. The base 54 is provided with a groove-shaped steel plate at the upper end of the base 54 except for bearing the total weight of the optical cable, etc., nine sections of damping sections are made of thin steel plates in the groove and are used for being connected with the cantilever 532 of the speed limiting turntable 53 so as to adjust the rotating speed of the optical cable tray.
An automatic opening and braking system is designed under the base 54 and consists of six braking plates 543, a connecting rod 545, a slope component, a moment rod 544 and the like. The brake plate 543 is normally closed, and in the non-operating state, is brought into close contact with the brake friction disc 535 at the lower part of the speed limit dial 53 by the urging spring, and the speed limit dial 53 is in the braking state.
The ramp component is divided into an up-down moving ramp component 546 and a rotating ramp component 547, the up-down moving ramp component 546 is connected with the connecting rod 545, the rotating ramp component 547 is integrated with the moment rod 544, the moment rod 544 is in a non-working state and is positioned at the middle left and right positions of the optical cable tray, when the optical cable is pulled forwards, small transverse thrust is generated on the moment rod 544, the rotating ramp component 547 at the end of the moment rod 544 is driven to rotate, the up-down moving ramp component 546 is lifted up, the brake plate 543 is driven by the connecting rod 545 to be separated from the lower brake friction disc 535, and the optical cable tray starts to be normally laid. When the cable stops pulling forward, the torque rod 544 resumes its home position and the brake plate 543 also immediately resets the brake disc rotation.
In some optional implementations provided by the embodiments of the present invention, the paying-off end of the optical cable spool may be fixed first, and then the semi-automatic optical cable laying device is towed by the trailer to move, so as to implement optical cable laying.
As can be seen from the above description, the embodiment of the invention provides a semi-automatic optical cable laying device, which can be matched with a lifting appliance on a trailer to simultaneously lay optical cables in the up-down direction of an optical cable line according to the double-disc operation of a construction environment. Meanwhile, due to the design of the upper speed limiting turntable of the pay-off disc assembly, the speed control of the cable paying-off process of the cable reel and the automatic braking when the cable paying-off is stopped can be realized without depending on additional electric driving equipment, and the technical problems that the cable reel is complex in process of installing the cable reel and the rotating speed of the cable is difficult to control when the cable is pulled in the prior art are solved.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
