Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a device for simultaneous stripping of the insulation on both sides of a power cable. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible coverings, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] The remaining parts of power cables during production or laying, as well as scrapped cables due to the replacement of old and new products, can all be reused after stripping. The current cable stripping devices have the following two main shortcomings: First, the current cable stripping devices do not strictly limit the position of the cable to be stripped, which makes it easy for the device to deviate in position during the stripping process, resulting in inconsistent stripping depth of the stripping blade inside the cable and affecting the stripping quality; Second, the current stripping devices cannot be stored when not in use, resulting in a large space occupation and inconvenience for transportation and carrying. Utility Model Content

[0004] The purpose of this invention is to provide a device for simultaneous stripping of the insulation on both sides of a power cable, so as to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power cable double-sided synchronous stripping device includes a first support base and a second support base, with the second support base located on both sides of the first support base. A stripping mechanism is fixedly installed on the top of both the first and second support bases. Each stripping mechanism includes a support plate fixedly installed on the top of the first and second support bases. Multiple limiting rings are arranged above the support plate, with the inner diameter of each limiting ring being the same as the outer diameter of the cable. The lowest limiting ring is fixedly installed on the top side of the support plate. A pre-drilled hole is provided within each limiting ring, and a stripping blade is installed within the pre-drilled hole. One side of the stripping blade is located inside the limiting ring, and the other side extends to the outside of the pre-drilled hole. A limiting sliding hole is provided in the second support base, and a limiting slider is slidably installed within the limiting sliding hole. The bottom of the limiting slider is fixedly installed on the first support base, and the top of the limiting slider extends to the outside of the limiting sliding hole and is fixedly installed at the bottom of a stop block. Fastening screw holes are provided in both the stop block and the second support base, and fastening bolts are screwed into these screw holes.

[0007] Furthermore, multiple peeling knives located on the same side of the limiting ring are fixedly installed on one side of the same fixing plate.

[0008] Furthermore, the bottom of the fixing plate is fixedly installed on the first support base and the second support base, respectively.

[0009] Furthermore, the number of limiting rings is three, and the inner diameter of the three limiting rings decreases sequentially from top to bottom.

[0010] Furthermore, adjacent limiting rings are fastened together by a connecting plate.

[0011] Furthermore, the stop block and the second support base are in sliding contact.

[0012] Furthermore, a base plate is fixedly installed at the bottom of the second support base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting a limiting ring, this utility model ensures that during the cable stripping process, since the inner diameter of the limiting ring is the same as the outer diameter of the cable, the cable will not shift its position as it passes through the inside of the limiting ring. This keeps the depth of the stripping blade inside the cable constant, thus significantly improving the stripping quality.

[0015] 2. When the peeling device of this utility model is not in use, the fastening bolts can be loosened first, and then the second support base can be slid along the trajectory of the limiting sliding hole, so that the second support bases on both sides move towards the first support base, thereby greatly reducing the space occupied by the peeling device and making transportation and carrying more convenient.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-8 A power cable double-sided synchronous stripping device includes a first support base 1 and a second support base 2. The second support base 2 is located on both sides of the first support base 1. A stripping mechanism 3 is fixedly installed on the top of both the first support base 1 and the second support base 2. The stripping mechanism 3 includes a support plate 3a fixedly installed on the top of the first support base 1 and the second support base 2. A plurality of limiting rings 3b are arranged above the support plate 3a. The inner diameter of the limiting rings 3b is the same as the outer diameter of the cable, and the lowest limiting ring 3b is fixedly installed on the support plate 3a. On the top side, a pre-drilled hole 3c is provided inside the limiting ring 3b. A peeling knife 3d is installed inside the pre-drilled hole 3c. One side of the peeling knife 3d is located inside the limiting ring 3b, and the other side of the peeling knife 3d extends to the outside of the pre-drilled hole 3c. A limiting sliding hole 4 is provided inside the second support base 2. A limiting slider 5 is slidably installed inside the limiting sliding hole 4. The bottom of the limiting slider 5 is fixedly installed on the first support base 1, and the top of the limiting slider 5 extends to the outside of the limiting sliding hole 4 and is fixedly installed on the bottom of the stop block 6. The stop block 6 and the second support base 2 are in sliding contact. Fastening screw holes 7 are provided inside the stop block 6 and the second support base 2. Fastening bolts 8 are screwed into the fastening screw holes 7.

[0027] In the above embodiment, by setting a limiting ring 3b, during the cable stripping process, since the inner diameter of the limiting ring 3b is the same as the outer diameter of the cable, the cable will not shift its position as it passes through the inside of the limiting ring 3b, thereby keeping the depth of the stripping knife inside the cable constant and significantly improving the stripping quality.

[0028] When the peeling device is not in use, the fastening bolt 8 can be loosened first, and then the second support base 2 can be slid along the trajectory of the limiting sliding hole 4, so that the second support base 2 on both sides moves towards the first support base 1, thereby greatly reducing the space occupied by the peeling device and making transportation and carrying more convenient.

[0029] Specifically, multiple peeling knives 3d located on the same side of the limiting ring 3b are fixedly installed on one side of the same fixing plate 3f, and the bottom of the fixing plate 3f is fixedly installed on the first support base 1 and the second support base 2 respectively.

[0030] In the above embodiment, by fixing the stripper 3d on the fixing plate 3f, it is ensured that the position of the stripper 3d will not shift when the cable passes through the inner side of the limiting ring 3b.

[0031] Specifically, there are three limiting rings 3b, and the inner diameters of the three limiting rings 3b decrease sequentially from top to bottom.

[0032] In the above embodiments, the cable is a polyvinyl chloride insulated cable (PVC cable), which includes the following three standard diameter cables:

[0033] 1.5mm 2 The BV wire has a conductor diameter of approximately 1.38 mm, a nominal insulation thickness of 0.7 mm, and a calculated outer diameter of approximately 2.78 mm.

[0034] 2.5mm 2 The BV wire has a conductor diameter of approximately 1.78 mm, a nominal insulation thickness of 0.8 mm, and a calculated outer diameter of approximately 3.38 mm.

[0035] 4.0mm 2 The BV wire has a conductor diameter of approximately 2.25 mm, a nominal insulation thickness of 0.8 mm, and a calculated outer diameter of approximately 3.85 mm.

[0036] Specifically, two adjacent limit rings 3b are fastened together by a connecting plate 3e.

[0037] In the above embodiment, the connecting plate 3e is used to fix two adjacent limiting rings 3b together, thereby connecting multiple limiting rings 3b into a whole.

[0038] Specifically, a base plate 9 is fixedly installed at the bottom of the second support base 2.

[0039] In the above embodiments, the base plate 9 can serve as a fixed support.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
