Description

Technical Field

[0001] This utility model relates to the field of high-voltage construction equipment technology, specifically a quantitative wire laying device for high-voltage construction. Background Technology

[0002] High-voltage power line construction is a core component of power engineering, referring to the installation, laying, and commissioning of 1kV and above high-voltage power systems. It encompasses key operations such as substation construction, high-voltage cable laying, and transmission line erection. Construction requires specialized equipment and personnel to complete procedures such as cable laying, wiring, insulation testing, and grounding installation. Specifically, professionals are capable of measuring the length of cables and conductors in high-voltage power line construction scenarios and preparing laying devices such as electric cable reels to perform the laying operations.

[0003] However, existing high-voltage cable laying devices mostly rely on the rotation of the winding drum to lay the cable. During the laying process, the high-voltage cable is prone to lateral deviation and vertical swaying due to its own fluctuations or slight external interference, posing safety hazards and failing to guarantee the regularity of the laying trajectory. In addition, when it is necessary to change the laying angle during the laying process, the operator must manually change the angle of the cable or move the equipment, which is not only labor-intensive but also prone to safety risks and affects the construction progress. Therefore, a quantitative cable laying device for high-voltage construction is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative cable laying device for high-voltage construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative cable laying device for high-voltage construction, comprising a support, a winding drum rotatably mounted inside the support, an I-shaped plate on one side of the winding drum, two first legs and two second legs symmetrically mounted on the bottom of the I-shaped plate, a support rail fixedly connected to the adjacent side of the two second legs, a sliding groove on the top of the I-shaped plate, a cable threading mechanism installed between the sliding groove and the support rail, the cable threading mechanism being used to thread high-voltage cables, and an adjustment mechanism mounted on the first legs, the adjustment mechanism being used to adjust the swing angle of the cable threading mechanism.

[0006] As a further preferred embodiment of this technical solution: the threading mechanism includes a threading cylinder, and two fixed sleeves are symmetrically fixedly connected to the outer wall of the threading cylinder. A first slider and a second slider are respectively rotatably installed at the ends of the two fixed sleeves. The first slider is slidably installed inside the groove, and the second slider is slidably installed on the support guide rail.

[0007] As a further preferred embodiment of this technical solution: the adjustment mechanism includes a second motor installed on one side of the first support leg, the rotation shaft of the second motor passing through the first support leg and fixedly connected to a lead screw, one end of the lead screw being rotatably installed on the inner wall of the other first support leg, a movable block being threaded onto the lead screw, a first connecting rod being hinged to one side of the movable block, a second connecting rod being hinged to the end of the first connecting rod, and the end of the second connecting rod being hinged to the outer wall of the fixed sleeve.

[0008] As a further preferred embodiment of this technical solution: both ends of the winding drum are fixedly connected to a fixed plate, two support rods are symmetrically hinged to one side of the bracket, a support wheel is installed at the end of the support rod, the support wheel is in contact with the outer wall of the fixed plate, a spring is fixedly connected to the bottom of the support rod, and one bottom end of the spring is fixedly connected to the other side of the bracket.

[0009] As a further preferred embodiment of this technical solution: the top of the I-shaped plate is symmetrically provided with a plurality of equally spaced threaded holes, and the first slider is fixed to the threaded holes by bolts.

[0010] As a further preferred embodiment of this technical solution: a first motor is installed on one side of the bracket, and the rotating shaft of the first motor is fixedly connected to one end of the winding drum.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model effectively solves the problem of cable deviation and swaying, ensuring the neatness and safety of cable laying. In response to the problem that cables are prone to deviation and swaying due to their own fluctuations or external interference during cable laying in existing devices, the cable is passed through the cable threading cylinder by the cooperation of the I-shaped plate, the slide groove, the support rail and the cable threading mechanism. The cable threading cylinder slides along the slide groove by the first slider and along the support rail by the second slider, which achieves stable support and position adjustment, effectively limiting cable swaying and deviation, ensuring neat cable laying trajectory, reducing safety hazards and improving the safety of high-voltage construction.

[0013] 2. This utility model can automatically adjust the laying angle, reduce labor intensity and avoid safety risks. It addresses the problem that existing devices require manual operation to adjust the laying angle, which is labor-intensive and has safety risks. It relies on the adjustment mechanism to adjust automatically. The second motor drives the lead screw to rotate, which drives the movable block to move. The movable block pushes the wire-threading drum to rotate through the connecting rod, changing the laying angle. There is no need for manual contact with the cable or moving the equipment, which greatly reduces labor intensity, avoids safety risks and ensures construction progress.

[0014] 3. This utility model can effectively improve the stability of the winding drum and optimize the basic conditions for wire laying. The fixed plates at both ends of the winding drum, together with the support rod, support wheel and spring on the bracket, the spring tension makes the support wheel close to the fixed plate, forming a stable radial support for the winding drum, reducing its radial runout when rotating. The rolling friction of the support wheel and the buffering effect of the spring further improve the stability of the winding drum, provide a good foundation for the smooth laying of the cable, and indirectly ensure the quality of wire laying.

[0015] 4. This utility model can adapt to multiple scenarios, enhancing the practicality of the device. The top of the I-shaped plate is provided with several equidistant threaded holes, and the first slider is fixed to different threaded holes by bolts. The position of the wire-threading drum can be adjusted according to the wire-laying span and the width of the construction area. Furthermore, the first motor drives the winding drum, and the wire-laying speed can be controlled by adjusting the rotation speed to achieve quantitative wire laying. The multi-level adjustment and speed controllable design allow the device to adapt to different high-voltage construction scenarios, significantly enhancing its practicality and flexibility.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1

[0023] Please see Figures 1-4This utility model provides a technical solution: a quantitative wire laying device for high-voltage construction, including a support 1.

[0024] Among them, such as Figure 1 As shown, a winding drum 2 is rotatably installed inside the bracket 1. An I-shaped plate 8 is provided on one side of the winding drum 2. Two first legs 9 and two second legs 10 are symmetrically installed on the bottom of the I-shaped plate 8. A support rail 16 is fixedly connected to the adjacent side of the two second legs 10. A sliding groove 12 is provided on the top of the I-shaped plate 8. A wire threading mechanism is installed between the sliding groove 12 and the support rail 16. The wire threading mechanism is used to thread high-voltage cables. An adjustment mechanism is installed on the first legs 9. The adjustment mechanism is used to adjust the swing angle of the wire threading mechanism.

[0025] like Figure 1 As shown, the threading mechanism includes a threading cylinder 15. Two fixed sleeves 21 are symmetrically fixed to the outer wall of the threading cylinder 15. A first slider 14 and a second slider 22 are rotatably mounted on the ends of the two fixed sleeves 21, respectively. The first slider 14 is slidably mounted inside the slide groove 12, and the second slider 22 is slidably mounted on the support guide rail 16. The support guide rail 16 cooperates with the slide groove 12 on the top of the I-shaped plate 8 to provide sliding guidance for the threading mechanism. In the threading mechanism, high-voltage cables can pass through the threading cylinder 15. The two fixed sleeves 21 on the outer wall of the threading cylinder 15 are respectively connected to the first slider 14 and the second slider 22. The two sliders slide on the slide groove 12 and the support guide rail 16, respectively.

[0026] In this embodiment, specifically: both ends of the winding drum 2 are fixedly connected to a fixed disk 4, two support rods 5 are symmetrically hinged to one side of the bracket 1, a support wheel 6 is installed at the end of the support rod 5, the support wheel 6 is attached to the outer wall of the fixed disk 4, a spring 7 is fixedly connected to the bottom of the support rod 5, and one end of the bottom of the spring 7 is fixedly connected to the other side of the bracket 1.

[0027] The support rod 5 hinged on the bracket 1, through the spring 7, ensures that the support wheel 6 at the end is always in close contact with the outer wall of the fixed disk 4, forming radial support for the winding drum 2 and reducing the radial runout when the winding drum 2 rotates. At the same time, the rolling friction between the support wheel 6 and the fixed disk 4, in conjunction with the spring 7, plays a certain buffering role.

[0028] like Figure 1 As shown, the adjustment mechanism includes a second motor 11 installed on one side of the first support leg 9. The rotation shaft of the second motor 11 passes through the first support leg 9 and is fixedly connected to a lead screw 17. One end of the lead screw 17 is rotatably installed on the inner wall of the other first support leg 9. A movable block 18 is threaded onto the lead screw 17. A first connecting rod 19 is hinged to one side of the movable block 18. A second connecting rod 20 is hinged to the end of the first connecting rod 19. The end of the second connecting rod 20 is hinged to the outer wall of the fixed sleeve 21.

[0029] In this embodiment, specifically: the adjustment mechanism drives the lead screw 17 to rotate through the second motor 11, causing the movable block 18 on the lead screw 17 to move laterally. The movable block 18 drives the hinged first connecting rod 19 and second connecting rod 20 to swing horizontally, causing the fixed sleeve 21 to drive the cable-threading drum 15 to rotate, thereby adjusting the cable exit angle in the opening of the cable-threading drum 15, adapting to the needs of different working positions and heights in high-voltage construction, and eliminating the need for frequent manual contact to adjust the cable exit angle.

[0030] Example 2

[0031] Reference Figures 1-3 This embodiment provides a quantitative cable laying device for high-voltage power construction. Based on the basic technical solution of Embodiment 1, the device has a number of equidistant threaded holes 13 symmetrically arranged on the top of the I-shaped plate 8. The first slider 14 is fixed to the threaded hole 13 by bolts. When the position of the cable-threading cylinder 15 is slidably adjusted to the appropriate position, the first slider 14 is fixed in the corresponding threaded hole 13 by bolts to realize the positioning of the cable-threading cylinder 15. The number of equidistant threaded holes 13 provides multiple fixed positions for the first slider 14, so that the cable-threading cylinder 15 can be adjusted to fix the fixed point on the I-shaped plate 8 according to the requirements of the cable laying span, the width of the construction area, etc.

[0032] In this embodiment, specifically: a first motor 3 is installed on one side of the bracket 1, and the rotating shaft of the first motor 3 is fixedly connected to one end of the winding drum 2. The first motor 3 serves as the power source for the rotation of the winding drum 2, and the rotation speed of the winding drum 2 can be adjusted by adjusting the rotation speed of the first motor 3 to control the quantitative wire feeding operation of the high-voltage cable.

[0033] Working principle: During use, the winding drum 2 can realize the basic wire laying operation of the high-voltage cable by rotating. The first foot 9 and the second foot 10 at the bottom of the I-shaped plate 8 form a stable support. The support guide rail 16 cooperates with the sliding groove 12 at the top of the I-shaped plate 8 to provide sliding guidance for the wire threading mechanism. In the wire threading mechanism, the high-voltage cable can pass through the wire threading drum 15. The two fixed sleeves 21 on the outer wall of the wire threading drum 15 are respectively connected to the first slider 14 and the second slider 22. The two sliders slide on the sliding groove 12 and the support guide rail 16 respectively, thereby providing support and sliding adjustment for the wire threading drum 15, effectively preventing the cable from deviating or shaking during wire laying, and ensuring that the wire laying trajectory is neat.

[0034] In addition, the adjustment mechanism drives the lead screw 17 to rotate via the second motor 11, causing the movable block 18 on the lead screw 17 to move laterally. The movable block 18 drives the hinged first connecting rod 19 and second connecting rod 20 to swing horizontally, causing the fixed sleeve 21 to drive the cable reel 15 to rotate, thereby adjusting the cable exit angle in the opening of the cable reel 15. This adapts to the needs of different working positions and heights in high-voltage construction, and eliminates the need for frequent manual contact to adjust the cable exit angle, thus improving the construction efficiency and quality of high-voltage cable laying.
