Description

Technical Field

[0001] This utility model relates to the field of cable support technology, and in particular to a cable support device for electromechanical installation. Background Technology

[0002] In the field of engineering electromechanical equipment installation, cables serve as a crucial link connecting process transmission equipment and control systems. The stability and safety of their laying path directly affect the overall system's operational efficiency. In actual construction, cables are mostly fixed and laid using installation supports within cable trays, cable trenches, or cable tunnels. Among these, cable supports, as the core components supporting cables, play an indispensable role in building power distribution wiring and wire installation, providing a stable load-bearing foundation for the cables.

[0003] However, during the temporary phase of electromechanical installation, cables need to be temporarily erected to meet construction requirements. Existing temporary erection devices have significant drawbacks in practical application: when the cable length is insufficient and needs to be extended by dragging, the operation is extremely inconvenient, increasing the labor intensity of construction workers. Furthermore, the cable's own weight during dragging causes continuous scraping between the cable and the erection device. This scraping phenomenon can easily damage the cable's outer insulation layer or internal conductor, affecting the cable's service life and potentially leading to safety hazards such as leakage and short circuits, posing a serious threat to construction safety and subsequent equipment operation. Therefore, a technical solution to the cable dragging problem during temporary erection is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a cable support device for electromechanical installation, which can solve the above-mentioned technical problems.

[0005] This utility model provides a cable support device for electromechanical installation, including a support base with a guide groove. A concave wheel is provided within the guide groove, with both ends of the concave wheel rotatably connected to the inner wall of the guide groove. A three-legged conical base is provided at the bottom of the support base, including three support legs inclined and fixed to the bottom of the support base. Lateral wheel sets are provided on opposite inner walls of the guide groove. By setting the concave wheel, the cable rests on the top of the concave wheel, avoiding friction between the cable and the guide groove, facilitating cable laying and dragging. During construction, the concave wheel can rotate with the dragging of the cable, thereby reducing friction between it and the cable and preventing the entire device from overturning due to the cable being dragged by construction machinery. Furthermore, when the cable deviates laterally (e.g., turning or being dragged obliquely), the cable generates a lateral force on the lateral wheel sets, pushing the lateral wheel sets to rotate, avoiding rigid friction between the cable and the edge of the guide groove.

[0006] Furthermore, the guide groove has a U-shaped structure and is rotatably connected to the support base.

[0007] Furthermore, the support base has a rectangular structure, and multiple guide grooves are provided on the support base at intervals along its length, all of which are rotatably connected to the support base.

[0008] Furthermore, a rotating shaft is fixedly connected to the bottom of the guide groove, and a circular turntable is fixedly sleeved on the rotating shaft. The support base has a slot that matches the circular turntable. By setting the rotating shaft and the circular turntable, when the direction of cable movement changes, the circular turntable can rotate synchronously to change the orientation of the guide groove axis, thereby minimizing friction between the cable and the side of the guide groove.

[0009] Furthermore, the side wall of the support is threaded with a wing bolt, the end of which is pressed against the rotating shaft and can be manually locked when the direction needs to be fixed.

[0010] Furthermore, the top of the guide groove is provided with an arc-shaped protective plate, which includes a left protective plate and a right protective plate. One end of the left protective plate and one end of the right protective plate are respectively hinged to the top of the guide groove, and the other ends are respectively provided with magnetic blocks or matching buckles. The left protective plate and the right protective plate form a closed limiting device, which can prevent the cable from falling off the guide groove.

[0011] Furthermore, a key is provided at the bottom of the guide groove, and a keyway matching the key is provided at the top of the rotating shaft. The key is located in the keyway, and the two are fixedly connected by screws located on the side of the rotating shaft.

[0012] Furthermore, a sleeve is provided on the lower side of the support leg, the top of the sleeve is hinged to the support leg, a retractable support foot is provided inside the sleeve, the bottom of the support foot is a pointed structure, a limiting ring is fitted on the support leg, the inner wall of the limiting ring is provided with internal threads, and the support leg portion located on the movement path of the limiting ring is provided with external threads that match the internal threads.

[0013] Furthermore, the length of the support leg is greater than the vertical distance from the sleeve to the bottom of the support leg.

[0014] Furthermore, the side wall of the support foot is provided with a groove, a spring is provided in the groove, a ball plunger is fixedly connected to the outer end of the spring, and the sleeve is provided with a plurality of through holes at equal intervals along its axial direction for the ball plunger to pass through.

[0015] Beneficial effects:

[0016] This invention utilizes a rotatable concave wheel within the guide groove of the support base. When the cable is laid on top of the concave wheel, it rotates synchronously with the cable during the dragging process, transforming the sliding friction between the cable and the installation device into rolling friction, significantly reducing dragging resistance. This design effectively solves the problem of inconvenient cable dragging operations in existing temporary installation devices, significantly reducing the labor intensity of construction workers and improving the construction efficiency of cable laying and extension during the temporary installation phase. The concave structure of the wheel provides stable support for the cable, preventing direct contact and scratching between the cable and the guide groove. Simultaneously, the lateral wheel assembly on the inner wall of the guide groove, when the cable deviates laterally (e.g., turning or oblique dragging), is subjected to the lateral force of the cable and rotates accordingly, transforming the rigid friction between the cable and the edge of the guide groove into rolling friction. This prevents damage to the cable's outer insulation layer and internal conductor from both longitudinal and lateral dimensions. This not only extends the cable's service life but also fundamentally reduces safety hazards such as leakage and short circuits caused by cable damage, effectively ensuring the safety of the construction process and subsequent equipment operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1

[0033] A cable support device for electromechanical installation, such as Figure 1-4 As shown, the device includes a support base 1, a guide groove 2 on the support base 1, and a concave wheel 3 inside the guide groove 2. The two ends of the concave wheel 3 are rotatably connected to the inner wall of the guide groove 2. A tripod cone-shaped base is located at the bottom of the support base 1, and the base includes three support legs 4 inclined and fixed to the bottom of the support base 1. Lateral wheel sets 5 are provided on opposite inner walls of the guide groove 2. By setting the concave wheel, the cable is laid on top of the concave wheel, avoiding friction between the cable and the guide groove, facilitating cable laying and dragging. During construction, the concave wheel can rotate with the dragging of the cable, thereby reducing friction between it and the cable and preventing the entire device from overturning due to the construction machinery dragging the cable. Furthermore, when the cable deviates laterally (such as turning or being dragged obliquely), the cable generates a lateral force on the lateral wheel sets, pushing the lateral wheel sets to rotate, avoiding rigid friction between the cable and the edge of the guide groove.

[0034] The guide groove 2 has a U-shaped structure, and the support base 1 has a rectangular structure. Multiple guide grooves 2 are spaced along the length of the support base 1, and all are rotatably connected to the support base 1. Specifically, a rotating shaft 6 is fixedly connected to the bottom of the guide groove 2, and a circular turntable 7 is fixedly fitted on the rotating shaft 6. The support base 1 has a groove 8 that matches the circular turntable 7. The two are fitted with a clearance fit, ensuring that the circular turntable 7 can rotate freely within the groove 8, while the groove 8 provides radial restraint to the circular turntable 1, preventing the rotating shaft 6 from shifting or wobbling during rotation, thus ensuring the stability and accuracy of the guide groove 2's rotation. By setting the rotating shaft 6 and the circular turntable 7, when the cable's movement direction changes, the circular turntable 7 can rotate synchronously to change the axial orientation of the guide groove 2, thereby minimizing friction between the cable and the side of the guide groove 2. Besides free rotation, the guide groove 2 can also be manually adjusted in angle. A wing bolt 9 is threaded onto the side wall of the support base 1, with the end of the bolt pressing against the rotating shaft; it can be manually tightened to fix the direction. Once the guide groove is adjusted to the required angle, tighten the wing bolt. Its end will press tightly against the outer surface of the rotating shaft, and the friction generated between the two will limit the rotation of the rotating shaft, thereby locking the guide groove securely at the current angle.

[0035] In addition, a key 11 is provided at the bottom of the guide groove 2, and a keyway 12 matching the key 11 is provided at the top of the rotating shaft 6. The key 11 is located in the keyway 12, and the two are fixedly connected by screws 13 located on the side of the rotating shaft 6. During installation, the key is precisely embedded in the keyway. Through the cooperation between the key and the keyway, torque can be effectively transmitted to ensure that the guide groove and the rotating shaft rotate synchronously. At the same time, in order to prevent the key from falling out of the keyway, the two are fixedly connected by screws located on the side of the rotating shaft. The screws pass through the side wall of the rotating shaft and press against the side of the key, so that the key and the keyway fit tightly, ensuring the reliability of the connection.

[0036] In addition, each guide slot is rotatably connected to the support base, meaning that the angle of each guide slot can be adjusted independently. When multiple cables with different routes need to be laid simultaneously, operators can adjust the angle of each guide slot separately, so that each cable can be laid along the optimal path, greatly improving the flexibility and orderliness of parallel installation of multiple cables.

[0037] Example 2

[0038] The basic structure is the same as in Example 1, such as... Figure 5 As shown, the difference is that the top of the guide groove 2 is provided with an arc-shaped guard plate 10, which includes a left guard plate and a right guard plate. One end of the left guard plate and one end of the right guard plate are respectively hinged to the top of the guide groove 2, and the other ends are respectively provided with magnetic blocks or matching buckles. The left guard plate and the right guard plate form a closed limiting device, which can prevent the cable from falling off the guide groove.

[0039] Example 3

[0040] The basic structure is the same as in Example 2, such as... Figure 6-10 As shown, the difference lies in that the lower side of the support leg 4 is provided with a sleeve 14, the top of which is hinged to the support leg 4. A retractable support foot 15 is provided inside the sleeve 14, and the bottom of the support foot 15 has a pointed structure. A limiting ring 16 is fitted onto the support leg 4, and the inner wall of the limiting ring 16 has an internal thread. The portion of the support leg 4 located on the movement path of the limiting ring 16 has an external thread 17 that matches the internal thread. The length of the support foot 15 is greater than the vertical distance from the sleeve 14 to the bottom of the support leg 4. A groove 18 is provided on the side wall of the support foot 14, and a spring 19 is provided inside the groove 18. A ball-head plunger 20 is fixedly connected to the outer end of the spring 19. The sleeve 14 has multiple through holes 21 evenly spaced along its axial direction for the ball-head plunger 20 to pass through.

[0041] This embodiment is suitable for softer ground. When used on softer ground, the support leg 15 is inserted into the ground to achieve positioning and prevent tipping. The specific usage method is as follows: A connecting plate 22 is fixedly connected to the top of the sleeve 14, and a groove 23 is provided on the side of the support leg 4. The connecting plate 22 is located in the groove 23 and is rotatably connected to the inner wall of the groove 23 (connected by a damping shaft). This achieves a complete hinge connection between the sleeve 14 and the support leg 4. The rotation angle of the connecting plate 22 can be limited according to the length of the groove or the filling material inside the groove, so that when the connecting plate 22 and the support leg 4 are at their maximum opening angle, the sleeve 14 points vertically to the ground.

[0042] First, rotate the sleeve 14 to its maximum opening angle. Then, press the ball plunger 20 by hand to retract it. Next, gradually pull the support leg 15 out of the sleeve 14 by holding the bottom of the support leg 15. Adjust the extension length of the support leg 15 by adjusting the through holes 21 at different positions of the ball plunger 20. After the support leg 15 is extended, rotate the limiting ring 16 upwards so that it is positioned at the angle between the sleeve 14 and the support leg 4. Figure 7 As shown, to prevent the sleeve 14 from rotating, the support foot 15 is then inserted into the ground to enhance the stability of the entire device.

[0043] After use, rotate the limiting ring 16 to move it away from the angle between the sleeve 14 and the support leg 4, then gradually retract the support leg 15 into the sleeve 14, and then rotate the sleeve 14 to fit the support leg 4. Figure 8 As shown, the limiting ring 16 at the bottom at this time serves to cover the tip of the support foot, preventing the user from being stabbed by the tip when transporting or storing the entire device.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
