Description

Technical Field

[0001] The utility model relates to the field of power cable installation, in particular to a power cable installation traction device. Background Art

[0002] In today's society, electricity is a vital form of energy, and its transmission and distribution rely on reliable power cable systems. With the rapid development of the economy and the continuous advancement of urbanization, the demand for electricity continues to grow, and the laying and installation of power cables are becoming increasingly frequent and important.

[0003] In the prior art, for example, a Chinese patent with publication number CN221369908U discloses an electric cable installation and traction device, including a base. The electric cable installation and traction device can adjust the distance between the driven turntable and the driving turntable by driving the driven turntable to move through a sliding adjustment component, and then can press electric cables of different outer diameters between the pipeline guide grooves of the driving turntable and the driven turntable for traction and transportation, enriching the general use scope of the cable traction component and improving the flexibility of use of the cable traction component.

[0004] During use of the above technical solution, when the sliding adjustment assembly adjusts the distance between the driven turntable and the driving turntable, since the guide sleeve is fixed on the base and cannot be moved, it cannot be ensured that the guide sleeve is in the middle plane between the driven turntable and the driving turntable when the power cable is placed, and thus it cannot be ensured that the power cable can be placed on the guide sleeve, which reduces the support for the power cable and affects the traction effect of the power cable. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a power cable installation and traction device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric power cable installation and traction device, comprising a base, a cable traction assembly, a sliding adjustment assembly and a guide sleeve, a slider is slidably installed in the sliding adjustment assembly, and a screw rod threadedly connected to the slider is rotatably installed in the sliding adjustment assembly, a handle is fixedly installed on the top of the screw rod, an active connecting rod rotatably connected to the outer wall of the guide sleeve is rotatably installed on the outer wall of the cable traction assembly, a group of sleeves are rotatably installed on the outer wall of the cable traction assembly, a driven connecting rod rotatably connected to the outer wall of the guide sleeve is rotatably installed on the outer wall of the sleeve, and a sliding groove corresponding to the guide sleeve is provided on the top of the base.

[0007] By adopting the above technical solution, when the user needs to pull a power cable with a large diameter, the screw rod can be rotated to make the slider slide. At this time, the cable pulling assembly slides with the slider. Since the lengths of the active connecting rod and the driven connecting rod are unchanged and equal, when the cable pulling assembly slides with the slider, the active connecting rod drives the guide sleeve to move, and the sliding distance of the guide sleeve in the horizontal direction is half of the sliding distance of the slider, thereby ensuring that when the slider slides, the guide sleeve can move simultaneously with the slider, and the guide sleeve is always in the middle position of the cable pulling assembly.

[0008] The present invention is further configured such that the end of the screw rod mounting handle is located outside the sliding adjustment assembly, and the mounting position of the screw rod is staggered with the mounting position of the cable pulling assembly.

[0009] By adopting the above technical solution, it is more convenient for the user to turn the handle, and the cable pulling assembly and the screw rod do not affect each other.

[0010] The present invention is further configured such that the slide grooves are symmetrically opened on the base, and the slide grooves are designed as inclined grooves inclined toward the direction of the sliding adjustment component.

[0011] By adopting the above technical solution, the inclination direction of the sliding groove is consistent with the sliding direction of the guide sleeve.

[0012] The present invention is further configured such that the horizontal plane where the top of the active connecting rod is located and the horizontal plane where the top of the driven connecting rod is located are parallel to the top of the base, and the installation positions of the multiple groups of active connecting rods and the multiple groups of driven connecting rods are staggered.

[0013] By adopting the above technical solution, the multiple sets of active connecting rods and the multiple sets of driven connecting rods will not affect each other, and the multiple sets of active connecting rods and the multiple sets of driven connecting rods parallel to the top of the base can ensure that the multiple sets of active connecting rods and the multiple sets of driven connecting rods can be smoothly linked when the slider slides.

[0014] The utility model is further configured such that the active connecting rod and the driven connecting rod are symmetrically installed in multiple groups, the length of the active connecting rod is the same as the length of the driven connecting rod, and the cross-section of the multiple symmetrically installed active connecting rods and the driven connecting rods is diamond-shaped.

[0015] By adopting the above technical solution, when the slider slides, multiple groups of active connecting rods and driven connecting rods can move synchronously, thereby improving stability.

[0016] The utility model is further configured such that protrusions are symmetrically mounted on the outer walls of both sides of the slider, and the slider is slidably connected to the sliding adjustment assembly via the protrusions.

[0017] By adopting the above technical solution, the slider can slide stably in the sliding adjustment assembly.

[0018] The present invention is further configured such that a threaded hole corresponding to the screw rod is formed through the slider, and the slider is threadedly connected to the screw rod through the threaded hole.

[0019] By adopting the above technical solution, when the screw rod is rotated, the slider can slide on the outer wall of the screw rod.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model is provided with a screw rod, an active connecting rod, a driven connecting rod and a guide sleeve. When the user needs to pull the power cable with a large diameter, the screw rod can be rotated to make the slider slide. At this time, the cable pulling assembly slides with the slider. Since the lengths of the active connecting rod and the driven connecting rod are unchanged and equal, when the cable pulling assembly slides with the slider, the active connecting rod drives the guide sleeve to move, and the sliding distance of the guide sleeve in the horizontal direction is half of the sliding distance of the slider, thereby ensuring that when the slider slides, the guide sleeve can move simultaneously with the slider, and the guide sleeve is always in the middle position of the cable pulling assembly.

[0030] A power cable installation and traction device, such as Figure 1 - Figure 5As shown, it includes a base 1, a cable pulling assembly 101, a sliding adjustment assembly 102 and a guide sleeve 8. A slider 2 is slidably installed in the sliding adjustment assembly 102, and a screw rod 3 threadedly connected to the slider 2 is rotatably installed in the sliding adjustment assembly 102 to facilitate moving the slider 2. A handle 4 is fixedly installed on the top of the screw rod 3 to facilitate rotating the screw rod 3 through the handle 4. An active connecting rod 6 rotatably connected to the outer wall of the guide sleeve 8 is rotatably installed on the outer wall of the cable pulling assembly 101. A sleeve 5 is rotatably installed on the outer wall of a group of cable pulling assemblies 101, so that when the cable pulling assembly 101 rotates, the active connecting rod 6 does not rotate with the cable pulling assembly 101. A driven connecting rod 7 rotatably connected to the outer wall of the guide sleeve 8 is rotatably installed on the outer wall of the sleeve 5. A sliding groove 11 corresponding to the guide sleeve 8 is provided on the top of the base 1, so that the guide sleeve 8 can slide stably on the sliding groove 11.

[0031] See also Figure 1 - Figure 4 The end of the screw rod 3 where the handle 4 is mounted is located on the outside of the sliding adjustment assembly 102, making it more convenient for the user to turn the handle 4, and the installation position of the screw rod 3 is staggered with the installation position of the cable pulling assembly 101, so that the cable pulling assembly 101 and the screw rod 3 do not affect each other.

[0032] See also Figure 1 - Figure 4 The slide groove 11 is symmetrically opened on the base 1 , and the slide groove 11 is designed as an inclined groove inclined toward the sliding adjustment component 102 , so that the inclined direction of the slide groove 11 is consistent with the sliding direction of the guide sleeve 8 .

[0033] See also Figure 1 and Figure 2 The horizontal plane at the top of the active connecting rod 6 and the horizontal plane at the top of the driven connecting rod 7 are parallel to the top of the base 1. The installation positions of the multiple sets of active connecting rods 6 and the multiple sets of driven connecting rods 7 are staggered, so that the multiple sets of active connecting rods 6 and the multiple sets of driven connecting rods 7 will not affect each other, and the multiple sets of active connecting rods 6 and the multiple sets of driven connecting rods 7 parallel to the top of the base 1 can ensure that when the slider 2 slides, the multiple sets of active connecting rods 6 and the multiple sets of driven connecting rods 7 can be smoothly linked.

[0034] See also Figure 1 - Figure 3 There are multiple groups of active connecting rods 6 and driven connecting rods 7 symmetrically installed, and the length of the active connecting rod 6 is the same as the length of the driven connecting rod 7, so that when the slider 2 slides, the multiple groups of active connecting rods 6 and driven connecting rods 7 can move synchronously, and the cross-section of the multiple groups of symmetrically installed active connecting rods 6 and driven connecting rods 7 is diamond-shaped, which makes the stability better.

[0035] See also Figure 4 - Figure 5, protrusions are symmetrically installed on the outer walls of both sides of the slider 2, and the slider 2 is slidingly connected to the sliding adjustment component 102 through the protrusions, so that the slider 2 can slide stably in the sliding adjustment component 102.

[0036] See also Figure 1 - Figure 4 A threaded hole corresponding to the screw rod 3 is opened in the slider 2, and the slider 2 is threadedly connected to the screw rod 3 through the threaded hole, so that when the screw rod 3 is rotated, the slider 2 can slide on the outer wall of the screw rod 3.

[0037] The working principle of the present utility model is as follows: when the diameter of the power cable that the user needs to pull is large, the handle 4 can be rotated to drive the screw rod 3 to rotate inside the slider 2. At this time, the slider 2 slides inside the sliding adjustment assembly 102. Since the cable pulling assembly 101 is fixedly installed on the top of the slider 2, the cable pulling assembly 101 slides with the slider 2. Since the lengths of the active connecting rod 6 and the driven connecting rod 7 are unchanged and equal, when the cable pulling assembly 101 slides with the slider 2, the active connecting rod 6 rotates on the outer wall of the cable pulling assembly 101. At the same time, the active connecting rod 6 drives the guide sleeve 8 to move, and the sliding distance of the guide sleeve 8 in the horizontal direction is half of the sliding distance of the slider 2. This ensures that when the slider 2 slides, the guide sleeve 8 can move simultaneously with the slider 2, and the guide sleeve 8 is always in the middle position of the cable pulling assembly 101.
