Description

Technical Field

[0001] The invention belongs to the field of cable construction, and in particular relates to a cable joint insulation layer grinding device. Background Art

[0002] During the laying and maintenance of the power system, cables are important carriers for transmitting electric energy, and their connection quality and safety are of vital importance. Due to the limitation of cable length, it is often necessary to connect two sections of cable through an intermediate joint to ensure the continuity and stability of power transmission. The production of intermediate joints is a complex and delicate process, in which the polishing of the insulation layer is one of the key steps to ensure the quality and electrical performance of the joint. Good polishing of the insulation layer can not only improve the insulation strength of the joint, but also reduce the risk of heat and failure caused by poor contact.

[0003] Traditionally, the grinding of the insulation layer of cable joints is mainly done by hand-held grinders. Although this method is flexible, it has many shortcomings: first, manual grinding is inefficient and time-consuming, and the grinding quality is limited by the skills and experience of the operator, making it difficult to ensure the uniformity and consistency of the grinding; second, the lack of stability when manually clamping the cable makes it difficult to accurately control the grinding position, which can easily lead to over- or under-grinding and affect the overall performance of the joint; third, during the manual grinding process, the operator is directly exposed to the rotating grinding tool, which poses a high safety risk, such as flying sparks, debris, and accidentally touching the rotating parts.

[0004] In order to overcome the limitations of manual grinding, semi-automatic cable insulation grinding equipment has gradually appeared on the market. This type of equipment usually includes a fixing device for clamping the cable and a sliding connection grinding mechanism, which is driven by a motor and uses an annular grinding belt to grind the insulation layer. This design improves the grinding efficiency to a certain extent, reduces manual intervention, and improves the grinding efficiency.

[0005] However, existing grinding equipment still has some technical difficulties. One significant problem is that the equipment usually only fixes one side of the cable, and the cable, as a flexible material, is prone to swing due to uneven force during the grinding process. This swing not only reduces the grinding accuracy and affects the grinding quality, but also may cause the cable to touch the operator during the swinging process, increasing safety risks. In addition, due to the swinging of the cable, the contact area and force between the grinding belt and the insulation layer are difficult to maintain constant, further exacerbating the problem of uneven grinding. Summary of the invention

[0037] like Figure 1 , Figure 2 As shown, a cable joint insulation layer grinding device comprises two supports 1, each of which is connected to a first guide rod 11 at both ends of the two supports 1, wherein a first fixing device 2 is provided on one of the supports 1, and a second fixing device 3 is provided on the other support 1. Figure 3 , Figure 4 As shown, the first fixing device 2 and the second fixing device 3 both include a base 22, an arc-shaped seat 23 is provided in the middle of the base 22, a U-shaped frame 21 is provided on the upper part of the base 22, guide bars 27 are provided on the inner walls of both sides of the U-shaped frame 21, a slide seat 24 is slidably connected to the inner side of the U-shaped frame 21, an arc-shaped clamping plate 25 is provided at the lower part of the slide seat 24, a clamping screw 26 is rotatably connected to the upper part of the slide seat 24, and the clamping screw 26 is threadedly connected to the U-shaped frame 21; The arc-shaped clamping plate 25 and the arc-shaped seat 23 clamp the cable. When the insulating layer is polished, the first fixing device 2 is used to clamp the cable, and the second fixing device 3 clamps the cable core after the insulating layer is stripped, so that the cable is in a straight state. This not only avoids the swing of the cable end during polishing to affect the polishing effect, but also avoids injuries caused by the swing of the cable end. At the same time, this straight state also facilitates the polishing operation and improves the polishing efficiency.

[0038] like Figure 6-Figure 8 As shown, a rotating base 5 is provided on the first guide rod 11, and the rotating base 5 includes an inner cylinder 51, and arms 52 are symmetrically connected to both sides of the inner cylinder 51, and the lower ends of the arms 52 are mounted on the first guide rod 11, and the outer cylinder 54 is rotatably connected to the outer cylinder 51 through a bearing 53, and a first fixing plate 56 is fixedly mounted on one side of the outer cylinder 54, and the grinding assembly 7 is mounted on the first fixing plate 56; like Fig. 9As shown, the grinding assembly 7 includes an L-shaped connecting seat 71, and a plurality of connecting rods 73 are provided on both sides of the L-shaped connecting seat 71.

During the grinding process, the outer cylinder 54 is rotated to realize the surrounding grinding of the insulating layer. This surrounding grinding also avoids the phenomenon of missed grinding or heavy grinding that may occur in the traditional grinding method, thereby improving the grinding quality and work efficiency.

[0040] After one grinding is completed, the insulating layer can be continuously ground by pushing the rotating base 5 forward a certain distance. This design not only improves the grinding efficiency, but also ensures the continuity and stability of the grinding process. At the same time, this feeding method also facilitates the control and adjustment of the operator, and improves the usability and operability of the device.

Combined with the automatic feeding of the stud, the degree of automation of the insulating layer grinding operation is further improved, ensuring that the grinding belt 79 can contact the insulating layer evenly and continuously, thereby improving the uniformity and quality of grinding and greatly reducing the labor intensity of the operators.

[0045] When the double-headed screw 47 is rotated, the two extrusion blocks 44 move closer to or farther away from each other, and under the action of their own structure, the extrusion blocks 44 move upward or downward, thereby realizing the adjustment of the height of the first fixing device 2 and / or the second fixing device 3, ensuring the coaxiality of cables of different diameters with the rotating base 5 after being fixed, thereby ensuring the consistency of the grinding force of the insulation layer at different positions.

[0046] like Fig. 9 As shown, a plurality of plug-in holes are provided on both sides of the L-shaped connecting seat 71, and one end of the connecting rod 73 is inserted into the plug-in hole with a gap.
