Description

Technical Field

[0001] The invention belongs to the technical field of cable trimming, and in particular relates to a cable shaping device. Background Art

[0002] At present, my country's power grid is developing rapidly and steadily. As a result, various updated transmission equipment and cable lines are widely used in the construction of daily distribution networks in urban areas.

[0003] In the construction environment with small intervals for power distribution construction, construction workers complete the bending of cables through two people's cooperation. This process will use tools such as crowbars, ropes, and wooden boards. However, if in an energized working environment, construction workers must be very careful to operate metal products such as crowbars to avoid the risk of electric shock. However, after the existing cable bending tools bend the cables after bundled, due to the uneven force, they often cause asymmetric extrusion deformation of the cable ends. In severe cases, it will cause cracking of the sealing tube, severe dents of extrusion deformation of the copper shielding layer and the semi-conductive layer and even the main insulation layer, which will reduce the original service life of the cable segment by about half. Therefore, in view of the existing construction situation, there is an urgent need for an efficient, stable and safe cable shaping device to replace the operation mode of forcibly bending the cable by manpower or using tools such as crowbars. Summary of the invention

[0004] The object of the present invention is to provide a cable shaping device which can solve the problem that when existing cable harness bending tools perform bending operations on cable harnesses, the cable ends are bent asymmetrically due to unbalanced force, and effective bending is difficult to perform using manpower.

[0005] In order to achieve the above-mentioned purpose, the present invention designs a cable shaping device, including a horizontally placed fixed plate, a clamping limit piece and a double-piston hydraulic cylinder, the double-piston hydraulic cylinder is located on the upper surface of the fixed plate, the clamping limit piece is located on the top of the double-piston hydraulic cylinder, and the relative fixation of the positions of the fixed plate and the double-piston hydraulic cylinder is achieved by the clamping limit piece, the double-piston hydraulic cylinder extends left and right in the horizontal direction, and a top receiving ball is provided at the end of the hydraulic rod of the double-piston hydraulic cylinder; the clamping limit piece is detachably connected to the fixed plate; and a limit column is provided on the upper surface of the fixed plate.

[0006] Furthermore, the clamping limit piece is a U-shaped piece with an opening upward, and the U-shaped bottom end of the clamping limit piece is provided with a plug-in column extending vertically downward. A space for accommodating and fixing the double-piston hydraulic cylinder is formed by the four plug-in columns, and the double-piston hydraulic cylinder is clamped in the space. Plug-in holes are provided in sequence from front to back on the upper surface of the fixed plate, and the detachable connection between the clamping limit piece and the fixed plate is realized by the engagement of the plug-in columns of the clamping limit piece with the plug-in holes on the fixed plate, and the relative fixation of the positions of the fixed plate and the double-piston hydraulic cylinder is realized.

[0007] Furthermore, there are four plug-in columns, and the four plug-in columns are respectively located at the four corners of the U-shaped bottom end of the clamping limiter; there are two rows of plug-in holes on the upper surface of the fixed plate, two of which correspond to one row of plug-in holes, and the other two plug-in columns correspond to the other row of plug-in holes.

[0008] Furthermore, four limiting columns are arranged on the upper surface of the fixing plate, wherein the distance between two adjacent limiting columns is smaller than the distance between the other two adjacent limiting columns.

[0009] Furthermore, the model of the double-piston hydraulic cylinder is cp-180.

[0010] Beneficial effects of the present invention:

[0011] The cable bender consists of a fixed plate, a clamping limiter and a double-piston hydraulic cylinder. The hydraulic rod of the double-piston hydraulic cylinder and the reaction force of the cable are used to simultaneously complete the bending of the cables on both sides, which can effectively reduce the labor intensity of construction workers, save time and labor, and the bending amplitude of the cable is between 0-40 degrees, and the bending angles of the cables on both sides are symmetrical and consistent. The pushing stroke of the double-piston hydraulic cylinder is not less than 20CM, and the pushing force is not less than 1 ton.

[0012] The overall material of the device is light and strong. The fixing plate can be made of a12 mold aluminum through a quenching process, so that the bending tool not only ensures working performance, but is also light and durable. The weight is less than half of that of traditional steel materials. At the same time, the application of split hydraulic structure makes construction more convenient.

[0013] In a narrow construction environment, it can avoid people from entering the cabinet to bend the cable, thereby reducing the possibility of people touching the point interval. When in use, one construction worker can adjust the curvature of the entire cable end connector, saving a lot of cable angle adjustment time and improving operational efficiency. At the same time, it will not damage the entire cable, ensuring the reliable operation of the cable terminal.

[0014] The device of the present invention has the characteristics of simple structure, convenient use and easy assembly and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0019] Example 1

[0020] like Figure 1-3 As shown, a cable shaping device includes a horizontally placed fixing plate 1 ( Figure 1 is a top view of the fixed plate 1), a clamping limiter 2 and a double-piston hydraulic cylinder 3, wherein the double-piston hydraulic cylinder 3 is located on the upper surface of the fixed plate 1, the clamping limiter 2 is located on the top of the double-piston hydraulic cylinder 3, and the relative fixation of the positions of the fixed plate 1 and the double-piston hydraulic cylinder 3 is achieved by the clamping limiter 2, the double-piston hydraulic cylinder 3 extends left and right in the horizontal direction, and a top receiving ball 31 is provided at the end of the hydraulic rod of the double-piston hydraulic cylinder 3; the clamping limiter 2 is detachably connected to the fixed plate 1, the model of the double-piston hydraulic cylinder is cp-180, and the air inlet end of the double-piston hydraulic cylinder 3 can be connected to a hydraulic pump when in use.

[0021] The clamping limit piece 2 is a U-shaped piece with an opening upward, and plug-in columns 21 extending vertically downward are provided at the four corners of the U-shaped bottom end of the clamping limit piece 2. A space for accommodating and fixing the double-piston hydraulic cylinder 3 is formed by the four plug-in columns 21, and the double-piston hydraulic cylinder 3 is clamped in the space. Two rows of plug-in holes 12 are provided in sequence from front to back in the middle of the upper surface of the fixed plate 1. The plug-in columns 21 of the clamping limit piece 2 and the plug-in holes 12 on the fixed plate 1 are engaged with each other to realize the detachable connection between the clamping limit piece 2 and the fixed plate 1, and the relative fixation of the positions of the fixed plate 1 and the double-piston hydraulic cylinder 3 is realized.

[0022] Two limiting posts 11 are disposed on both left and right sides of the upper surface of the fixing plate 1 , wherein the distance between the two limiting posts 11 close to the cable bundle 41 is smaller than the distance between the two limiting posts 11 far from the cable bundle 41 .

[0023] Before use, first separate the three bundles of cables 41 that need to be bent and shaped in the cable bundle 4, place the middle bundle of cables 41 in the U-shaped groove in the middle of the clamping limiter 2, and then place the double-piston hydraulic cylinder 3 in the horizontal direction, and the top balls 31 at the left and right ends of the double-piston hydraulic cylinder 3 respectively connect the left and right bundles of cables 41, and then place the clamping limiter 2 on the top of the double-piston hydraulic cylinder 3, and insert the plug-in column 21 into the plug-in hole 12 according to the positions where the left and right bundles of cables 41 need to be shaped. At this time, the clamping limiter 2 clamps and fixes the double-piston hydraulic cylinder 3 through the front and rear plug-in columns 21, and at the same time, the plug-in column 21 is inserted into the plug-in hole 12, and the piston rod of the double-piston hydraulic cylinder 3 is started to extend, and the top ball 31 applies pressure to the cable 41 to bend the parts of the left and right bundles of cables 41 that need to be bent.

[0024] If it is necessary to adjust the bending parts of the left and right cable bundles 41, the clamping limiter 2 can be separated from the fixing plate 1, and then the plug-in column 21 can be inserted into other plug-in holes 12 to change the relative position of the clamping limiter 2 and the fixing plate 1, thereby realizing the bending needs of different positions of the left and right cable bundles 41.
