Description

Technical Field

[0001] This invention relates to the field of electromechanical construction technology, and in particular to a cable installation device. Background Technology

[0002] When constructing cable terminations, the outer sheath, steel armor, and inner sheath of the cable need to be removed to expose the three-phase wires. Then, the ends of each phase wire are processed separately. During this process, the outer ends of the three wires need to be separated. Because the inner ends of the three wires remain connected, the outer ends can easily come together again, affecting construction efficiency. Currently, construction workers essentially have to process the ends while constantly adjusting the positions of the three wires, which is very inconvenient.

[0003] To address the above situation, a cable installation device is provided to facilitate the separation of three-phase cables during cable terminal installation. Summary of the Invention

[0004] The purpose of this invention is to provide a cable installation device.

[0005] The present invention is achieved by the following measures: a cable installation device, characterized in that it includes a clamping assembly, an inner support assembly, and a plurality of tension springs connecting the clamping assembly and the inner support assembly; The clamping assembly includes a ring that clamps the outside of the cable, the ring being composed of two semi-circular rings joined together; The inner support assembly includes a fixed plate, with a frustum-shaped rubber block concentrically arranged at one end of the fixed plate and a round rod concentrically arranged at the other end of the fixed plate. A positioning plate is concentrically arranged on the round rod. Three outer support rods are evenly distributed circumferentially on the fixed plate. The outer support rods are rotatably mounted on the fixed plate. By rotating the outer support rods, the outer ends of the outer support rods can move closer to or away from the center of the fixed plate. The positioning plate has three adjusting rods evenly distributed circumferentially, each corresponding to one of the outer support rods. One end of each adjusting rod is bolted to the positioning plate, and the other end of the adjusting rod can press against the inner side of the outer support rod. One end of the tension spring is connected to the ring body, and the other end is connected to the fixed plate.

[0006] There are three tension springs evenly distributed around the circumference, and the tension springs are located between two adjacent outer support rods.

[0007] The outer end of the outer support rod is rotatably provided with a U-shaped plate, and the outer end of the U-shaped plate is fixedly provided with an arc-shaped outer support plate. A flexible pad is provided on the outer wall of the arc-shaped outer support plate.

[0008] The round rod is mounted on the fixed plate by a support frame. The support frame includes several columns evenly distributed on the fixed plate. The outer end of each column is fixedly mounted with a mounting plate. The round rod is a screw. The mounting plate is equipped with a motor with a reducer to drive the screw to rotate. The screw is equipped with an optical shaft section. It also includes a fixed base, the screw passes through the fixed base and the optical axis segment on the screw is rotatably mounted on the fixed base, the positioning disk is connected to the fixed base; the optical axis segment is rotatably connected to the fixed base through a bearing, and the fixed base and the positioning disk are fixedly connected by a connecting sleeve.

[0009] A winding post is threadedly connected to the screw and located outside the fixed base. The winding post includes two parallel and concentric circular plates connected by several connecting rods. One of the circular plates has a threaded hole concentric with the screw. The middle part of the connecting rod is connected by a ring. A connecting ring is provided on the ring. A clip is connected to the connecting ring by an elastic element. The clip can clamp the plastic support strip of the cold shrink tubing.

[0010] The round rod is fixed on the fixed plate, and the round rod is a screw rod. The positioning plate is set on the screw rod by a threaded connection.

[0011] Rubber pads are provided on the inner walls of both semi-circular rings.

[0012] The elastic element is generally an elastic rope, and the clamp can be selected from existing finished products according to actual needs.

[0013] For separate wires, cold shrink tubing is needed for wrapping. Cold shrink tubing is made by injecting and vulcanizing liquid silicone rubber in the factory, then expanding it and lining it with a plastic spiral support. During on-site installation, these pre-expanded parts are fitted onto the treated cable ends or joints, the internal plastic support strip is pulled out, and it is pressed against the cable insulation, relying on elastic recoil force at room temperature. When pulling out the plastic support strip, it is usually done manually, with one hand pulling it out and the other hand pressing down on the cold shrink tubing at the pulled-out position and making appropriate adjustments, which is very inconvenient. Therefore, the winding post is designed so that the clamps on the winding post clamp onto the plastic support strip to be pulled out. Then, the motor is started, and the motor rotation drives the screw and winding post to rotate. After the elastic element tightens, it pulls the plastic support strip, causing it to wind around the winding post, thus achieving the extraction of the plastic support strip. During use, the motor operates at low speed. The winding post is located in the middle position, and when pulling out plastic support strips from other wires, the position of the clamps can be adjusted freely.

[0014] The winding post is threadedly connected to the screw. Rotating the winding post can adjust the position of the clamp and the entire winding post to accommodate cold shrink tubing of different lengths.

[0015] In use, the small end of the rubber block is close to the connection of the three-phase lines, and the outer wall of the rubber block is in contact with the three lines at the same time. Rotate and adjust the position of the outer support rod so that the outer ends of the three outer support rods are respectively against different lines. After adjusting the angle of the three lines, push the adjusting rod against the support rod and tighten it with bolts. Finally, clamp the clamping assembly on the cable to fix the device. When it is necessary to remove the plastic support strip from the cold shrink tubing, the threaded hole on the winding post can be installed on the screw. After reaching the appropriate position, the clamp is used to hold the plastic support strip, and the motor is started to rotate the winding post. As the clamp rotates, the plastic support strip is pulled out and wound around the connecting rod, thus removing the plastic support strip. The same procedure can be performed to remove the plastic support strips on the other two phase lines.

[0016] The beneficial effects of this invention are: it facilitates the separation of the three phase wires of the cable during cable terminal installation; it is equipped with a corresponding adjustable support structure to fix the separation angle; and it is equipped with a detachable winding post, which allows manual removal of the plastic support strip from the cold shrink tubing during installation.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] Example 1: See Figures 1-5 A cable installation device, characterized in that it includes a clamping assembly 1, an inner support assembly 2, and a plurality of tension springs 3 connecting the clamping assembly 1 and the inner support assembly 2; The clamping assembly 1 includes a ring 101 that clamps the outside of the cable 4. The ring 101 is composed of two semi-circular rings joined together. The inner support assembly 2 includes a fixed plate 201. A frustum-shaped rubber block 202 is concentrically arranged at one end of the fixed plate 201, and a round rod is concentrically arranged at the other end of the fixed plate 201. A positioning plate 2011 is concentrically arranged on the round rod. Three outer support rods 203 are evenly distributed circumferentially on the fixed plate 201. The outer support rods 203 are rotatably mounted on the fixed plate 201. When the outer support rods 203 are rotated, their outer ends can move closer to or away from the center of the fixed plate 201. Three adjusting rods 209, corresponding one-to-one with the outer support rods 203, are evenly distributed circumferentially on the positioning plate 2011. One end of the adjusting rod 209 is bolted to the positioning plate 2011, and the other end of the adjusting rod 209 can press against the inner side of the outer support rod 203. One end of the tension spring 3 is connected to the ring 101, and the other end is connected to the fixed plate 201.

[0021] There are three tension springs 3 evenly distributed around the circumference, and the tension springs 3 are located between two adjacent outer support rods 203.

[0022] The outer end of the outer support rod 203 is rotatably provided with a U-shaped plate 5, and the outer end of the U-shaped plate 5 is fixedly provided with an arc-shaped outer support plate 501. A flexible pad is provided on the outer wall of the arc-shaped outer support plate 501.

[0023] The round rod is mounted on the fixed plate 201 by a support frame. The support frame includes several columns 204 evenly distributed on the fixed plate 201. The outer end of the column 204 is fixedly mounted with a mounting plate 2013. The round rod is a screw 205. The mounting plate 2013 is equipped with a motor 2012 with a reducer to drive the screw 205 to rotate. The screw 205 is equipped with an optical shaft section. It also includes a fixed base 207, a screw 205 passing through the fixed base 207 and the optical axis section on the screw 205 being rotatably mounted on the fixed base 207, and a positioning disk 2011 connected to the fixed base 207; the optical axis section is rotatably connected to the fixed base 207 through a bearing 2011, and the fixed base 207 and the positioning disk 2011 are fixedly connected through a connecting sleeve 2010.

[0024] A winding post 208 is threadedly connected to the screw 205 and located outside the fixed base 207. The winding post 208 includes two parallel and concentric circular plates 2081. The two circular plates 2081 are connected by several connecting rods 2082. One circular plate 2081 is provided with a threaded hole 2087 concentric with the screw 205. The middle part of the connecting rods 2082 is connected by a ring 2083. A connecting ring 2086 is provided on the ring 2083. A clip 2085 is connected to the connecting ring 2086 by an elastic element 2084. The clip 2085 can clamp the plastic support strip of the cold shrink tubing.

[0025] Rubber pads 102 are provided on the inner walls of both semi-circular rings.

[0026] The elastic element 2084 is generally an elastic rope, and the clip 2085 can be selected from existing finished products according to actual needs.

[0027] For separate wires, cold shrink tubing is needed for wrapping. Cold shrink tubing is made by injecting and vulcanizing liquid silicone rubber in the factory, then expanding it and lining it with a plastic spiral support. During on-site installation, these pre-expanded parts are fitted onto the treated cable ends or joints, and the internal plastic support strip is pulled out and pressed against the cable insulation. It relies on elastic recoil force at room temperature. When pulling out the plastic support strip, it is usually done manually—one hand pulls it out while the other hand presses down on the cold shrink tubing at the pulled-out position and makes appropriate adjustments, which is very inconvenient. Therefore, a winding post 208 is designed. The clamp 2085 on the winding post 208 clamps the plastic support strip to be pulled out. Then, the motor 2012 is started. The rotation of the motor 2012 drives the screw 205 and the winding post 208 to rotate. After the elastic element 2084 tightens, it pulls the plastic support strip, causing it to wind around the winding post 208, thus enabling the plastic support strip to be pulled out. During use, the motor 2012 operates at low speed. The winding post 208 is located in the middle position. When the plastic support strip on other lines is pulled out, the position of the clip 2085 can be adjusted at will.

[0028] The winding post 208 is threadedly connected to the screw 205. Rotating the winding post 208 can adjust the position of the clamp 2085 and the position of the entire winding post 208 to accommodate cold shrink tubing of different lengths.

[0029] In use, the small end of the rubber block 202 is close to the connection of the three-phase line 401, and the outer wall of the rubber block 202 is in contact with the three lines at the same time. Rotate to adjust the position of the outer support rod 203 so that the outer ends of the three outer support rods 203 are respectively against different lines. After adjusting the angle of the three lines, the adjusting rod 209 is placed against the support rod and fixed by tightening the bolts. Finally, the clamping assembly 1 is clamped on the cable 4 to fix the device. When it is necessary to remove the plastic support strip from the cold shrink tubing, the threaded hole 2087 on the winding post 208 can be installed on the screw 205. After reaching the appropriate position, the clamp 2085 clamps the plastic support strip, and the motor 2012 is started to rotate the winding post 208. As the clamp 2085 rotates, the plastic support strip is pulled out and wound around the connecting rod 2082, thus removing the plastic support strip. The same method can be used to remove the plastic support strips on the other two phase lines 401.

[0030] Example 2: See Figures 1-6 A cable installation device includes a clamping assembly 1, an inner support assembly 2, and a plurality of tension springs 3 connecting the clamping assembly 1 and the inner support assembly 2. The clamping assembly 1 includes a ring 101 that clamps the outside of the cable 4. The ring 101 is composed of two semi-circular rings joined together. The inner support assembly 2 includes a fixed plate 201. A frustum-shaped rubber block 202 is concentrically arranged at one end of the fixed plate 201, and a round rod is concentrically arranged at the other end of the fixed plate 201. A positioning plate 2011 is concentrically arranged on the round rod. Three outer support rods 203 are evenly distributed circumferentially on the fixed plate 201. The outer support rods 203 are rotatably mounted on the fixed plate 201. When the outer support rods 203 are rotated, their outer ends can move closer to or away from the center of the fixed plate 201. Three adjusting rods 209, corresponding one-to-one with the outer support rods 203, are evenly distributed circumferentially on the positioning plate 2011. One end of the adjusting rod 209 is bolted to the positioning plate 2011, and the other end of the adjusting rod 209 can press against the inner side of the outer support rod 203. One end of the tension spring 3 is connected to the ring 101, and the other end is connected to the fixed plate 201.

[0031] There are three tension springs 3 evenly distributed around the circumference, and the tension springs 3 are located between two adjacent outer support rods 203.

[0032] The outer end of the outer support rod 203 is rotatably provided with a U-shaped plate 5, and the outer end of the U-shaped plate 5 is fixedly provided with an arc-shaped outer support plate 501. A flexible pad is provided on the outer wall of the arc-shaped outer support plate 501.

[0033] The round rod is fixed on the fixed plate 201. The round rod is a screw 205. The positioning plate 2011 is set on the screw 205 by a threaded connection.

[0034] Rubber pads 102 are provided on the inner walls of both semi-circular rings.

[0035] In use, the small end of the rubber block 202 is close to the connection of the three-phase line 401, and the outer wall of the rubber block 202 is in contact with the three lines at the same time. Rotate to adjust the position of the outer support rod 203 so that the outer ends of the three outer support rods 203 are respectively against different lines. After adjusting the angle of the three lines, the adjusting rod 209 is placed against the support rod and fixed by tightening the bolts. Finally, the clamping assembly 1 is clamped on the cable 4 to fix the device. In addition, since the positioning plate 2011 and the screw 205 are connected by a thread, the position of the positioning plate 2011 can be rotated to adjust the position of the adjusting rod 209, thereby further adjusting the angle of the outer support rod 203.

[0036] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here.
