[0001] The present invention relates to the technical field of cable supports, and in particular to a portable cable rack. Background Art

[0002] A large number of mechanical equipment are used in modern construction sites to improve construction efficiency and replace manual labor to complete tasks such as the transportation and installation of large structures. Since the equipment is scattered in many corners of the construction site and the power supply of large equipment needs to be temporarily built, the power supply lines are often laid and overlapped on the ground of the construction site, which is easily damaged by the equipment and construction workers, and may cause serious leakage. In particular, rainy weather is more likely to increase the risk of leakage. Therefore, it is necessary to erect power lines such as cables through temporary brackets.

[0003] However, the existing temporary brackets still have some shortcomings: 1. Although the existing temporary brackets can be installed in different directions, they usually only have one installation fixing point. The single-point steering installation setting easily leads to the loosening of the entire cable and poor fixing effect;

[0004] 2. The existing brackets are usually disassembled and carried because of their fixed structure, which is not convenient to carry and wastes time. Summary of the invention

When the cable rack needs to be transported, in order to facilitate carrying, the sliding cylinder can be controlled to move upward again, and the built-in rod can continue to deflect inward, thereby driving several second pivot blocks evenly arranged on the upper end of the base to retract synchronously, thereby shrinking the overall body frame for easy carrying.

[0016] 3. By setting up a supporting structure, the sliding baffle can move synchronously with the retraction of the second rotating shaft block, and the sliding baffle is used to protect the first insulating column and the second insulating column to prevent falling objects from hitting the first insulating column and the second insulating column, thereby affecting the fixing effect of the first insulating column and the second insulating column on the cable.

DETAILED DESCRIPTION

[0028] like Figure 1-10 As shown, a portable wire rack comprises a base 1, on which an adjustable telescopic structure is provided, the adjustable telescopic structure comprises a plurality of second rotating shaft blocks 11 which are evenly arranged at the upper end of the base 1 and can be retracted synchronously, a cable binding assembly is provided on the second rotating shaft block 11 and cables can be installed in different orientations between the cable binding assemblies, the cable binding assembly comprises a first insulating column 17 and a second insulating column 18 which can be adjusted in spacing according to the type of cable, a supporting structure matched with the adjustable telescopic structure is provided at the upper end of the base 1, the supporting structure comprises a plurality of sliding baffles 6 which are arranged at the upper ends of the first insulating column 17 and the second insulating column 18 and can move synchronously with the retraction of the second rotating shaft block 11.

[0029] When the present invention is in use, the base 1 supports and fixes the wire rack, controls the operation of the cable bundle assembly according to the type of cable, adjusts the spacing between the first insulating column 17 and the second insulating column 18, inserts the cable between the first insulating column 17 and the second insulating column 18, and clamps and fixes the cable using the first insulating column 17 and the second insulating column 18. Since the second rotating shaft blocks 11 are symmetrically arranged around the base 1, the cables can be installed in parallel or crosswise, with various installation methods and good installation effects. Moreover, since a distance is provided between the second rotating shaft blocks 11, compared with the single-point steering installation, although installation in different orientations can be achieved, the single-point steering installation only has one installation fixing point on the wire rack, which easily causes the entire cable to become loose, and the fixing effect is poor. Moreover, when it is necessary to adjust the cable installation height, the adjustable telescopic structure is controlled to operate to adjust the overall height of the second rotating shaft block 11. , and during the height adjustment of the second rotating shaft block 11, the second rotating shaft block 11 collectively tends to move axially toward the base 1, and the distance adjustment between the second rotating shaft blocks 11 becomes smaller, which can be adapted to the height adjustment to adjust the distance between the erection fixing points to ensure the erection and fixing effect of the cable. At the same time, when the distance between the second rotating shaft blocks 11 is adjusted, the supporting structure works, and the sliding baffle 6 moves synchronously with the retraction of the second rotating shaft block 11, and the sliding baffle 6 is used to protect the first insulating column 17 and the second insulating column 18 to prevent falling objects from hitting the first insulating column 17 and the second insulating column 18, affecting the fixing effect of the first insulating column 17 and the second insulating column 18 on the cable. When the wire rack needs to be transported, in order to facilitate carrying, the adjustable telescopic structure can be controlled to work again, and the multiple second rotating shaft blocks 11 evenly arranged on the upper end of the base 1 are synchronously retracted to shrink the overall body frame for easy carrying.

[0030] The adjustable telescopic structure also includes a central rotating frame 29 arranged at the center position of the base 1, and a plurality of built-in rods 5 are rotatably connected to the central rotating frame 29, one end of the built-in rod 5 is rotatably set on the second rotating shaft block 11, and the two ends of the second rotating shaft block 11 are rotatably connected to the first external rod 2 and the second external rod 3, respectively, and the lower ends of the first external rod 2 and the second external rod 3 are correspondingly rotatably set on the first rotating shaft block 4 corresponding to the second rotating shaft block 11, and the central rotating frame 29 is rotatably connected to the spiral rod 12, and the upper end of the central rotating frame 29 is provided with a sliding block 13, the inner wall of the sliding block 13 is fixedly connected to a screw barrel 14 threadedly connected to the spiral rod 12, and the sliding block 13 is rotatably connected to a sliding barrel 15 slidably set with the built-in rod 5.

[0031] like Figure 1-3As shown, the screw rod 12 is rotated. During the rotation of the screw rod 12, the screw barrel 14 on the inner wall of the slide block 13 is threadedly matched, thereby driving the slide block 13 to move upward along the axial direction of the screw rod 12. The slide block 13 drives the sliding cylinder 15 to move upward. Since the lower rotation axis point of the built-in rod 5 is fixed on the intermediate rotating frame 29, when the sliding cylinder 15 moves upward, it drives the built-in rod 5 to deflect upward accordingly. The built-in rod 5 drives the second rotation axis block 11 to move upward while tending to retract inward toward the screw rod 12. When the first When the second rotating shaft block 11 moves, it drives the first external rod 2 and the second external rod 3 at both ends to move respectively. The first external rod 2 and the second external rod 3 can be used to cooperate with the internal rod 5 to control the second rotating shaft block 11 to keep moving perpendicular to the direction of the base 1. Because the bottoms of the adjacent first external rod 2 and the second external rod 3 are respectively rotated and set on the first rotating shaft block 4, and the first rotating shaft block 4 and the second rotating shaft block 11 remain vertically parallel, the first rotating shaft block 4 can be used to fit the ground and cooperate with the base 1 to provide limited support for the overall wire rack.

[0032] The supporting structure also includes a support frame 10 fixedly arranged at the upper end of the sliding block 13, the upper end of the support frame 10 is fixedly connected to a fixed disk 9, the upper end of the spiral rod 12 is fixedly connected to a rotating rod 26, the upper end of the fixed disk 9 is rotatably connected to a spiral rotating disk 27, the upper end of the rotating rod 26 is rotatably arranged on the spiral rotating disk 27, a number of fixed pins 32 are evenly arranged on the spiral rotating disk 27, a deflection rod 28 is rotatably connected to the fixed pin 32, the upper end of the deflection rod 28 is correspondingly fixedly arranged at the lower end of the sliding baffle 6, a fixed plate 7 is arranged at the upper end of the spiral rotating disk 27, a number of the sliding baffles 6 are slidably arranged on the fixed plate 7, a clamping plate 8 is respectively arranged at both ends of the fixed plate 7, a support plate 31 fixedly connected to the fixed disk 9 is arranged at the lower end of the clamping plate 8, and the spiral rotating disk 27 is provided with spiral grooves arranged at equal intervals, and the width of the spiral grooves is greater than the diameter of the fixed pins 32.

[0033] like Figure 7-10As shown, the support frame 10 fixes the fixed disk 9 on the sliding support block 13, and a second handle 25 is provided on the rotating rod 26. The rotating rod 26 is driven to rotate by the second handle 25. Since a spline corresponding to the spiral rotating disk 27 is provided on the upper end of the rotating rod 26, the rotating rod 26 can drive the spiral rotating disk 27 to rotate without affecting the spiral rotating disk 27 sliding up and down along the axis of the rotating rod 26. The rotation of the spiral rotating disk 27 drives the spiral groove to rotate. During the rotation process, the spiral groove is meshed with the fixed pin 32 at one end of the deflection rod 28. Since one end of the deflection rod 28 is fixedly provided on the sliding baffle 6, During the rotation process, this spiral wire groove drives the fixing pin 32 to move toward the center end of the spiral turntable 27, and the fixing pin 32 drives the sliding baffle plate 6 to move axially toward the fixed plate 7 through the deflection rod 28. The fixed plate 7 is set on the fixed disk 9 by using the clamping plate 8 and the support plate 31, so that the sliding baffle plate 6 can move synchronously with the retraction of the second rotating shaft block 11, and the sliding baffle plate 6 is used to protect the first insulating column 17 and the second insulating column 18 to prevent falling objects from hitting the first insulating column 17 and the second insulating column 18, affecting the fixing effect of the first insulating column 17 and the second insulating column 18 on the cable.

[0034] The cable assembly also includes a vertical rod 22 fixedly arranged on the second rotating shaft block 11, the lower end of the vertical rod 22 is rotatably connected to a worm gear 21, the second rotating shaft block 11 is rotatably connected to a worm 19 meshing with the worm gear 21, the vertical rod 22 is rotatably connected to a turret plate 16, the lower end of the turret plate 16 is provided with a sleeve 30 coaxially fixedly connected to the worm gear 21, the first insulating column 17 and the second insulating column 18 are both sleeved on the vertical rod 22, the first insulating column 17 and the second insulating column 18 are respectively provided with symmetrically arranged deflection grooves 23, the turret plate 16 is provided with a pair of pins 24 meshing with the deflection grooves 23, and the vertical rod 22 is provided with splines corresponding to the first insulating column 17 and the second insulating column 18.

[0035] like Figure 4-6As shown, a first rotating handle 20 is provided at one end of the worm 19, and the worm 19 is driven to rotate by the first rotating handle 20, and the worm 19 drives the worm wheel 21 to rotate, and the worm wheel 21 drives the rotating frame plate 16 to rotate with the vertical rod 22 as the axis through the sleeve 30, and the rotating frame plate 16 drives the latches 24 at the upper and lower ends to rotate in a circle respectively. Since the latches 24 are respectively engaged with the deflection grooves 23 on the first insulating column 17 and the second insulating column 18, and the deflection grooves 23 are symmetrically arranged, since the vertical rod 22 is provided with the first The splines corresponding to the insulating column 17 and the second insulating column 18 are used to limit the rotation of the first insulating column 17 and the second insulating column 18. Therefore, when the rotating frame plate 16 drives the pin 24 to rotate in a circle, the first insulating column 17 and the second insulating column 18 are driven to move axially toward each other along the vertical rod 22 through the deflection groove 23, and the distance between the first insulating column 17 and the second insulating column 18 is adjusted. It is suitable for cables of different thicknesses, and the first insulating column 17 and the second insulating column 18 are used to clamp and fix the cables.

[0036] The working process of the present invention is as follows: when the present invention is in use, the base 1 supports and fixes the wire rack, the worm 19 is driven to rotate by the first rotating handle 20, the worm 19 drives the worm wheel 21 to rotate, the worm wheel 21 drives the rotating frame plate 16 to rotate with the vertical rod 22 as the axis through the sleeve 30, and the rotating frame plate 16 drives the latches 24 at the upper and lower ends to rotate in a circle respectively, because the latches 24 are engaged with the deflection grooves 23 on the first insulating column 17 and the second insulating column 18, and the deflection grooves 23 are symmetrically arranged, due to the vertical rod 22, the vertical rod 22 is rotated by the vertical rod 22. The axial rod 22 is provided with splines corresponding to the first insulating column 17 and the second insulating column 18, which are used to limit the rotation of the first insulating column 17 and the second insulating column 18. Therefore, when the rotating frame plate 16 drives the pin 24 to rotate in a circle, the first insulating column 17 and the second insulating column 18 are driven to move toward each other through the deflection groove 23, and the distance between the first insulating column 17 and the second insulating column 18 is adjusted. It is suitable for cables of different thicknesses, and the first insulating column 17 and the second insulating column 18 are used to clamp and fix the cables.

[0037] And because the second rotating shaft blocks 11 are symmetrically arranged around the base 1, the cables can be installed in parallel or crosswise, the installation methods are diverse, and the installation effect is good. Moreover, since there is a distance between the second rotating shaft blocks 11, compared with the single-point turning installation, although installation in different orientations can be achieved, the single-point turning installation has only one installation fixing point on the wire rack, which easily causes the overall cable to loosen and the fixing effect is not good.

[0038] When the cable installation height needs to be adjusted, since the rotating rod 26 and the spiral rotation are fixedly arranged, the spiral rod 12 is driven to rotate by rotating the rotating rod 26. During the rotation of the spiral rod 12, the spiral rod 12 cooperates with the thread of the screw barrel 14 on the inner wall of the sliding support block 13, thereby driving the sliding support block 13 to move upward along the axial direction of the spiral rod 12. The sliding support block 13 drives the sliding cylinder 15 to move upward respectively. Since the lower rotation axis point of the built-in rod 5 is fixed on the intermediate rotating frame 29, when the sliding cylinder 15 moves upward, it drives the built-in rod 5 to deflect upward respectively. The built-in rod 5 drives the second rotating shaft block 11 to move upward while tending to retract inwardly toward the direction of the spiral rod 12. When the second rotating shaft block 11 moves, it drives the first external rod 2 and the second external rod at both ends respectively. 3 movement, the first external rod 2 and the second external rod 3 can be used to cooperate with the internal rod 5 to control the second shaft block 11 to keep moving perpendicular to the base 1, and because the bottoms of the adjacent first external rod 2 and the second external rod 3 are respectively rotatably set on the first shaft block 4, and the first shaft block 4 and the second shaft block 11 keep moving in parallel directions, the first shaft block 4 can be used to fit on the ground, cooperate with the base 1 to limit the support of the overall wire rack, and during the height adjustment of the second shaft block 11, the second shaft blocks 11 collectively tend to move axially toward the base 1, and the distance between the second shaft blocks 11 is adjusted to be smaller, which can be adapted to the height adjustment to adjust the distance between the erection fixing points, thereby ensuring the erection and fixing effect of the cable.

[0039] At the same time, when the distance between the second rotating shaft blocks 11 is adjusted, the rotating rod 26 rotates. Since the upper end of the rotating rod 26 is provided with a spline corresponding to the spiral rotating disk 27, the rotating rod 26 can drive the spiral rotating disk 27 to rotate, and the rotation of the spiral rotating disk 27 drives the spiral groove to rotate. During the rotation process, the spiral groove engages with the fixed pin 32 at one end of the deflection rod 28, and since one end of the deflection rod 28 is fixedly arranged on the sliding baffle 6, the spiral groove drives the fixed pin 32 toward the spiral rotating disk during the rotation process. The center end of the disk 27 moves, and the fixing pin 32 drives the sliding baffle plate 6 to move axially toward the fixed plate 7 through the deflection rod 28. The fixed plate 7 is set on the fixed disk 9 by using the clamping plate 8 and the support plate 31. Therefore, the sliding baffle plate 6 can move synchronously with the retraction of the second rotating shaft block 11. The sliding baffle plate 6 is used to protect the first insulating column 17 and the second insulating column 18 to prevent falling objects from hitting the first insulating column 17 and the second insulating column 18, which will affect the fixing effect of the first insulating column 17 and the second insulating column 18 on the cable.

[0040] When the wire rack needs to be transported, in order to facilitate carrying, the sliding cylinder 15 can be controlled to move upward again, and the built-in rod 5 can continue to deflect inward, thereby driving a plurality of second rotating shaft blocks 11 evenly arranged on the upper end of the base 1 to retract synchronously, thereby shrinking the entire body frame for easy carrying.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
