Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to cable reel supports. Background Technology

[0002] Cable supports are generally fixed using brackets, commonly including angle steel brackets and prefabricated brackets. Currently, cable supports are needed in power installation to facilitate cable installation. However, existing cable supports cannot restrict the position of the cable during use, so the cable is prone to displacement, resulting in multiple cables getting tangled together, causing great inconvenience to users and reducing the practicality of existing cable supports. Although power cable supports have been technically improved, the current technology is still cumbersome to reel in cables and cannot adjust the distance between the cable and the ground.

[0003] Currently, during the on-site cable laying process, it is often necessary to drag the cable over long distances. In the past, the cable was dragged directly without any support. This not only caused the cable to sink to the ground due to its own weight, resulting in high friction and requiring a lot of physical labor from the workers, thus delaying the construction progress, but also the rough ground may damage the cable sheath. Damaged cables are prone to accidents and cannot be used, so they need to be repaired, which increases production costs. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a cable reel bracket.

[0005] The technical solution adopted by this invention to solve its technical problem is: A cable reel bracket includes a frame, a base, a crossbeam, and rollers. The frame includes a crossbar and vertical bars connected to both ends of the crossbar. The base includes a fixing block and a connecting rod disposed on the upper surface of the fixing block and perpendicular to the fixing block. The vertical bars are embedded in the connecting rods and are vertically connected to the connecting rods. The crossbeam is fixed between the vertical bars at both ends of the crossbar, and the crossbeam is parallel to the crossbar and located above the connecting rods. The crossbeam is provided with support rods spaced apart along the length of the crossbeam. A fixed shaft is provided between the support rods, and the fixed shaft is parallel to the crossbeam. Rollers for supporting and guiding cables are sleeved on the fixed shafts.

[0006] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the upper part of the connecting rod is provided with a positioning hole with an internal thread, and the vertical rod is provided with several through holes spaced apart along the height direction of the vertical rod. The center of the several through holes is on the same vertical plane as the center of the positioning hole. The connecting rod is provided with a positioning rod that passes through the positioning hole and the through holes. The positioning rod is provided with an external thread that matches the internal thread. When the positioning rod is removed, the vertical rod moves relative to the connecting rod along the height direction, so that the different through holes are aligned with the positioning hole. Then the positioning rod is passed through the positioning hole and the through hole to adjust the height of the cable shaft bracket.

[0007] Preferably, the crossbeam is provided with a groove extending along the length of the crossbeam, and two sliders are provided in the groove. The two sliders are fixedly connected to the bottom ends of the two support rods respectively. When the worker drags the cable along the width of the crossbeam, the cable can swing along the length of the crossbeam, without having to drag the cable straight along the width of the crossbeam, which makes it easier for the worker to drag the cable.

[0008] Preferably, a reinforcing block is provided between the upper surface of the fixing block and the lower part of the connecting rod. The reinforcing block extends downward from the lower part of the connecting rod to the upper surface of the fixing block along a direction perpendicular to the length of the crossbeam, thereby improving the stability of the cable shaft bracket.

[0009] Preferably, the four corners of the lower surface of the fixing block are provided with circumferentially rotatable pulleys, which facilitates moving the cable shaft bracket to the position where the cable needs to be supported.

[0010] Preferably, all pulleys are equipped with braking devices.

[0011] Preferably, the outer surface of the roller is arc-shaped, the circumference of the roller is arc-shaped, and the radius of the roller increases from the center to both ends along the axial direction, that is, the radius at both ends of the roller is greater than the radius of the inner side of the roller, so as to prevent the cable from detaching from the roller when swinging along the length of the crossbeam.

[0012] Preferably, the end faces of both ends of the roller are provided with countersunk grooves, and rolling bearings are provided in the countersunk grooves. The end faces of the rolling bearings are in contact with the bottom surface of the countersunk grooves. The outer ring of the rolling bearings is interference-fitted with the countersunk grooves, and the inner ring of the rolling bearings is interference-fitted with the fixed shaft, so that the rollers can rotate smoothly, making it convenient for workers to drag the cable, saving time and effort.

[0013] Preferably, a connecting beam is provided between the connecting rods, and the connecting beam is parallel to the crossbar to improve the structural strength of the cable shaft support.

[0014] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: The cable reel bracket is placed at the cable support point, and the cable is placed on the roller. When the worker drags the cable along the width of the crossbeam, the roller supports and guides the cable, making it easy for the worker to drag the cable, saving time and effort, and speeding up the construction progress. In addition, the rolling friction between the roller and the cable is small, avoiding damage to the cable during the laying process, avoiding the need for cable repair, and reducing production costs. Since the vertical rod can extend and retract relative to the connecting rod along the length of the vertical rod, the height of the cable reel bracket can be adjusted, making the cable reel bracket suitable for different environmental conditions and highly adaptable.

[0017] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0018] like Figures 1 to 4 As shown in the figure, this embodiment provides a cable reel bracket, including a frame 1, a base 2, a crossbeam 3, and rollers 4; the frame 1 includes a crossbar 1-1 and vertical bars 1-2 respectively connected to both ends of the crossbar 1-1; the base 2 includes a fixing block 2-1 and a connecting rod 2-2 disposed on the upper surface of the fixing block 2-1 and perpendicular to the fixing block 2-1; the vertical bars 1-2 are embedded in the connecting rods 2-2, and the vertical bars 1-2 and the connecting rods 2-2 are connected in a lifting manner; the crossbeam 3 is fixed between the vertical bars 1-2 at both ends of the crossbar 1-1, the crossbeam 3 is parallel to the crossbar 1-1, and the crossbeam 3 is located above the connecting rods 2-2; the crossbeam 3 is provided with support rods 5 spaced apart along the length direction of the crossbeam 3, and a fixed shaft 6 is provided between the support rods 5, the fixed shaft 6 is parallel to the crossbeam 3, and rollers 4 for supporting and guiding cables are sleeved on the fixed shaft 6.

[0019] In practice, the upper part of the connecting rod 2-2 is provided with a positioning hole with an internal thread. The vertical rod 1-2 is provided with several through holes spaced apart along the height direction of the vertical rod 1-2. The center of the several through holes is on the same vertical plane as the center of the positioning hole. The connecting rod 2-2 is provided with a positioning rod 7 that passes through the positioning hole and the through hole. The positioning rod 7 is provided with an external thread that matches the internal thread. When the positioning rod 7 is removed, the vertical rod 1-2 moves relative to the connecting rod 2-2 along the height direction, so that the different through holes are aligned with the positioning hole. Then the positioning rod 7 is passed through the positioning hole and the through hole, thereby adjusting the height of the cable shaft bracket. This allows the cable shaft bracket to be used in different environmental conditions, such as inside tunnels or in environments with height restrictions, making it highly adaptable.

[0020] The crossbeam 3 is provided with a groove 8 extending along the length of the crossbeam 3. Two sliders 9 are provided in the groove 8. The two sliders 9 are fixedly connected to the bottom ends of the two support rods 5 respectively. When the worker drags the cable along the width of the crossbeam 3, the cable can swing along the length of the crossbeam 3. It is not necessary to drag the cable straight along the width of the crossbeam 3, which makes it convenient for the worker to drag the cable.

[0021] A reinforcing block 10 is provided between the upper surface of the fixing block 2-1 and the lower part of the connecting rod 2-2. The reinforcing block 10 extends downward from the lower part of the connecting rod 2-2 to the upper surface of the fixing block 2-1 along the length direction perpendicular to the crossbeam 3. When the operator drags the cable along the width direction of the crossbeam 3, the force of the cable acting on the roller will be transmitted to the base 2. The presence of this reinforcing block 10 can improve the stability of the cable shaft support.

[0022] The lower surface of the fixing block 2-1 is provided with four rotatable pulleys 11 at its four corners, which facilitates the movement of the cable reel bracket to the position where the cable needs to be supported. The four corners of the lower surface of the fixing block 2-1 are also provided with threaded holes extending along the height of the fixing block 2-1. The pulleys 11 are threadedly connected to the threaded holes of the fixing block 2-1. The pulleys 11 can rotate 360° around the axis of the threaded holes of the fixing block, allowing the pulleys to move the cable reel bracket in any direction, making it easy for workers to move the cable reel bracket to the position where the cable needs to be supported.

[0023] All pulleys 11 are equipped with braking devices. If the pulleys are not equipped with braking devices, when workers drag the cable, they will also cause the cable shaft support to move, changing the support point of the cable, and may even cause the cable shaft support to tip over. In this embodiment, the braking device includes a brake pad, which is hinged to the mounting base of the pulley. The axis of the hinge between the pulley and the mounting base is parallel to the spindle of the pulley. After the cable shaft support is moved to the position where the cable needs to be supported, the brake pad is rotated around the axis, so that the brake pad moves towards the spindle of the pulley until it touches the surface of the pulley, so that the pulley can no longer rotate around the spindle, thus fixing the cable shaft support. When workers drag the cable, the cable shaft support will not move or tip over.

[0024] The outer surface of roller 4 is arc-shaped, and the circumference of roller 4 is also arc-shaped. The radius of roller 4 increases axially from the center to both ends, meaning the radius at both ends of roller 4 is greater than the radius on the inner side of roller 4. This prevents the cable from detaching from roller 4 when it swings along the length of crossbeam 3. In this embodiment, roller 4 includes end portions at both ends and a straight cylindrical portion located between the end portions. The diameters of the end portions are equal and larger than the diameter of the straight cylindrical portion. The difference between the radius of the end portions and the radius of the straight cylindrical portion is one-third of the diameter of the largest cable to be laid. Placing the cable on the straight cylindrical portion, i.e., between the end portions, better prevents the cable from detaching from roller when it swings along the length of crossbeam.

[0025] The roller 4 has countersunk grooves on both ends, and rolling bearings are installed in the countersunk grooves. The end faces of the rolling bearings are in contact with the bottom surface of the countersunk grooves. The outer ring of the rolling bearings is interference-fitted with the countersunk grooves, and the inner ring of the rolling bearings is interference-fitted with the fixed shaft 6, so that the roller 4 can rotate smoothly, making it convenient for workers to drag the cable, saving time and effort.

[0026] A connecting beam 12 is provided between the connecting rods 2-2. The connecting beam 12 is parallel to the crossbar 1-1, which improves the structural strength of the cable shaft support.
