Description

Technical Field

[0001] The present application relates to the field of cable technology, and in particular to a power cable bending thruster. Background Art

[0002] A cable is a special type of conductor. A cable is usually a rope-like cable made of several or several groups of conductors (at least two in each group), each group of conductors is insulated from each other and often twisted around a center, and the entire outside is covered with a highly insulating covering.

[0003] The existing patent (announcement number: CN207588362U) discloses a power cable bending thruster, whose structure includes a lower limit plate, a limit hole, a wheel, a limit block, an upper limit plate, a limit rod, a fixer, a hydraulic rod, a connecting rod, a hydraulic lever, and a rubber sleeve. The upper surface of the lower limit plate is fitted with the lower surface of the limit block, and the limit hole and the lower limit plate are an integrated structure. The utility model is a power cable bending thruster. The device is moved to a suitable position for fixing by the wheel, and the position of the limit block and the limit rod is adjusted to be fixed by the lower limit plate and the upper limit plate. The cable is placed between the limit block and the hydraulic rod, and the hydraulic lever is pressed. The oil in the cylinder will give the piston a left force, and the piston drives the piston rod to move to the left to bend the cable. The cylinder cover guide sleeve, the Y-shaped sealing ring and the O-shaped sealing ring prevent oil leakage. The wear-resistant ring is relatively wear-resistant, so that the piston is not easily damaged. The cable has a high hardness. It is more labor-saving and time-saving to use the hydraulic rod when bending, and it is more practical.

[0004] When the above device is bent, the position of the limit block and the limit rod is adjusted to fix them through the lower limit 1 and the upper limit plate. The cable is placed between the limit block and the hydraulic rod, and the hydraulic lever is pressed. The cylinder will give the piston a left force, and the piston drives the piston rod to move left to bend the cable. However, in the process of bending the cable, the middle end of the cable moves forward, which will cause the two sides of the cable to approach each other and rub against the surface of the limit block, which is easy to wear the cable. At the same time, in the process of bending, it is difficult for the worker to control the pressing amplitude by pressing the hydraulic lever, and then it is difficult to control the bending angle, and the accuracy is poor. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a power cable bending thruster with the advantages of easy operation, etc. It solves the problem that the middle end of the cable moves forward, causing the two sides of the cable to approach each other and rub against the surface of the limit block, which easily wears the cable. At the same time, during the bending process, it is difficult for the worker to control the pressing amplitude and thus the bending angle by pressing the hydraulic lever, resulting in poor precision.

[0011] Furthermore, two limit plates are fixedly connected to the upper surface of the bottom plate, and limit rods are slidably inserted into the interior of the two limit plates, and the rear ends of the two limit rods are fixedly connected to the clamping mold.

[0013] Furthermore, a sliding groove is provided on the upper surface of the bottom plate, the bottom of the circumferential frame is rotatably connected to a limiting column, and the limiting column is slidably connected to the sliding groove.

[0014] Through the above solution, by providing the sliding grooves and the limiting columns, the stability of the circumferential frame during rotation can be improved.

[0015] Furthermore, two power plates are fixedly connected to the upper surface of the circumferential frame, a threaded rod is rotatably connected between the two power plates, and the adjustment block is threadedly connected to the threaded rod.

[0016] Through the above solution, the distance between the bending wheel and the fixed mold can be adjusted through the threaded rod.

[0017] Furthermore, a rocker is fixedly connected to the front end of the threaded rod.

[0018] Through the above solution and the setting of the rocker, it is convenient for the user to rotate the threaded rod.

[0019] Furthermore, a bending shaft is rotatably connected to the upper surface of the base plate, the top end of the bending shaft is fixedly connected to the circumferential frame, a worm gear is fixedly connected to the outer surface of the bending shaft, two stabilizing plates are fixedly connected to the upper surface of the base plate, a worm is rotatably connected between the two stabilizing plates, and the worm gear is meshingly connected to the worm gear.

[0021] Furthermore, one end of the worm is fixedly connected to an external motor output end.

[0022] Through the above solution, by setting up an external motor, it is possible to provide power for the rotation of the worm.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This kind of power cable bending thruster can achieve the purpose of approaching the clamping mold to the fixed mold through the set electric push rod, thereby achieving the purpose of quickly clamping cables with different diameters; the set threaded rod can achieve the purpose of the slider driving the bending wheel to move, thereby achieving the effect of bending cables with different diameters; the set bending wheel is connected with the adjusting block through rotation, which can effectively reduce the wear intensity of the cable during bending; the set worm and worm wheel can effectively increase the rotation amplitude of the circumferential frame, thereby improving the accuracy of bending the cable.
