A secondary cable core straightening device

Abstract

The invention discloses a secondary cable core straightening device, comprising a fixed frame one, the fixed frame one is a concave structure, a hand hole is arranged on a vertical plate of the fixed frame one, two A plurality of rotating shafts are rotatably connected between two vertical plates, wherein one of the rotating shafts is connected to a motor, and the rotating shafts are connected by a tooth chain, and multiple sets of cable core clamping assemblies are arranged on the tooth chain, and the clamping The assembly includes a fixed frame two and a movable plate, the fixed frame two is concave, a movable plate is arranged between the two vertical plates of the fixed frame two, and the lower part of the movable plate is slidingly connected with the horizontal plate of the fixed frame two, so Bolts are arranged on a vertical plate of the second fixing frame, and the stud ends of the bolts are pressed against the movable plate. The present invention is simple in structure, flexible and convenient to use, and is suitable for secondary cables with long cable core straightening lengths.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a secondary cable core straightening device. Background technique [0002] In recent years, the number of conventional substation technical renovation projects has increased. During the construction process, the secondary cable treatment process takes up a lot of manpower and material resources. Among them, the finishing of the cable core is very important. The current treatment methods for the secondary cable finishing are: first, Manually peel off the cable sheath, comb the secondary wire core, and then fix the cable in the screen cabinet (cabinet), and then use needle-nose pliers to fix one wire core at a time, and gradually straighten and repair them one by one. This process needs to be repeated many times and the force should be uniform, so the requirements for the construction personnel's arm strength are relatively large. This method is time-consuming and labor-i...

Problems solved by technology

This method is time-consuming and labor-intensive, cannot continue to work, the wire core is straightened slowly, needs to be repaired separately, and consumes huge physical strength of the construction personnel, which affects the construction speed. At present, for the method of secondary cable core trimming, there are improper use of knives Scratches the workers and the insulation of the wire core. When the staff is inexperienced or weak, the wire core needs to be straightened many times. In addition, when the binding is not firm, the wire core needs to be reworked many times due to the movement of the entire cable.

[0003] The invention patent application with the publication number CN 103928877 A discloses a cable core automatic straightening device, which is composed of a frame part, a sliding seat part, a sliding seat fixing device, a power transmission part, and a cable core winding part; the cable core The winding part mainly includes a rotating disk, a clamping handle, a guide shaft fixing seat, a cable pressing head, and a connecting rod. There is an annular groove on the outer circle of the rotating disk, a straight groove in the middle of one end surface, and a straight groove on one side of the straight groove. Notch, the size of the notch can meet the needs of rotation when the cable clamping head is clamped. The other end of the winding disc is connected to the output end of the motor. There is a through groove on the upper part of the guide shaft fixing seat. Two guide shafts are arranged on the two walls of the through groove of the guide shaft fixing seat. The guide shaft fixing seat is fixed on the rotating disk. The other end of the connecting rod is hinged with the clamping handle, and the clamping handle is hinged with the guide shaft fixing seat. The motor drives the rotating disc to rotate through the motor to straighten the cable. The operation is convenient and flexible, and the straightening effect is good. But only one cable core can be straightened at a time, but the straightened cable cores are entangled together and are not easy to remove. If the length of the cable core to be straightened is longer, it will be more difficult to remove and inconvenient to use; the structure is complex, There are many parts, which is not conducive to maintenance

[0004] The Chinese utility model patent application with the notification number CN205967208U discloses a secondary cable straightening device, including a workbench, a first clamping mechanism, a second clamping mechanism, a rack and a gear; the first clamping mechanism includes a U-shaped frame And the clamping bolt, the clamping bolt thread is installed on the U-shaped frame; the second clamping mechanism includes the lower pressing plate, the upper pressing plate and the slider, the middle part of the lower pressing plate is provided with a locking stud, and the locking stud passes through the upper pressing plate And the lock nut is installed with a lock nut that fits with its thread; there is a guide rail on the workbench, the slider is slidably installed on the guide rail, the rack and the slider are fixedly connected, and the length direction of the rack and the length direction of the guide rail Parallel, the gear is installed on the workbench and meshed with the rack, and the gear is connected with the crank. This device saves time and effort, but every time the cable core is straightened, the second clamping mechanism needs to be returned to its original position, which is inconvenient to use; When the cable core is straightened, the length that needs to be pulled out is longer. When the length exceeds the length of the rack, the user needs to remove the cable core, and then return the second clamping mechanism to the original position to clamp the cable core again, which is inconvenient to use. The straightening efficiency is low; the straightening length of the wire core is the same as the moving distance of the straight rack. To meet the needs of pulling out a long cable, the length of the rack and the length of the worktable need to be increased, and the occupied area Big
