Description

Technical Field

[0001] This utility model belongs to the technical field of cable laying auxiliary devices, and in particular relates to a cable support frame. Background Technology

[0002] With the development of the power industry, the laying and application of power cables are becoming increasingly widespread. Power construction and other projects rely heavily on power cables. However, power cables are generally large in size, requiring multiple operators to lay them out. The current conventional method involves manually inserting the cable reel's rotating shaft into the center of the reel, then using a forklift to lift the reel and place both ends of the shaft on the support of the cable laying frame. This creates a distance between the reel and the ground to allow for rotation, facilitating cable laying and winding. Because forklift lifting is required, the operation involves numerous steps, is complex, and has low efficiency.

[0003] Chinese patent CN219859804U discloses a cable laying frame, which includes a frame body with a vertically mounted track assembly. The track assembly is equipped with a movable component, which includes an upper slider and a lower slider. An adjustable support is vertically connected between the upper and lower sliders. A locking device is provided between the lower slider and the track assembly. Two rollers are connected to the upper part of the upper slider, facing each other to the left and right. The design uses a hydraulic jack as the power lifting device, and the tangential rolling action of the rollers and the circular shaft facilitates the rotation and laying of the cable reel passing through the circular shaft.

[0004] However, the above solution has some shortcomings. The circular shaft, after passing through the spool, lacks a corresponding connection structure. Furthermore, the size of the circular shaft is smaller than the size of the spool's central hole, preventing the spool from rotating with the shaft and hindering the unloading operation. Simultaneously, the weight of both the circular shaft and the spool rests on the roller, resulting in excessive force on the roller and making it difficult to ensure its rotation. Utility Model Content

[0005] The purpose of this utility model is to provide a cable support frame to solve the problems existing in the background art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A cable support frame includes a support shaft, two sets of symmetrically arranged support frame bodies, and a jack located on the support frame bodies. The upper and lower ends of the jacks are respectively provided with an upper support plate and a lower support plate. The upper and lower support plates are slidably connected to the columns of the support frame bodies. The upper support plate is provided with a slot for placing the support shaft, and a universal ball bearing is provided in the slot. Two sets of limiting and locking components are provided on the support shaft near the center hole of the cable reel. The limiting and locking components include clamps and wedge blocks. Three sets of wedge blocks are evenly arrayed on the circumference of the clamps.

[0008] Furthermore, the clamp has a segmented structure, and the clamp is fixed to the support shaft by bolts.

[0009] Furthermore, a support block and a screw are provided between the clamp and the wedge block. The support block is fixed on the clamp, and the screw passes through the support block and connects to the large end of the wedge block.

[0010] Furthermore, the wedge block extends out of the clamp and is located on the support shaft, with the wedge block positioned between the support shaft and the center hole of the cable reel.

[0011] Furthermore, the screw is provided with a matching nut, which is located between the support block and the wedge block.

[0012] Furthermore, the groove is semi-circular, and the plurality of universal ball bearings are evenly arranged radially along the groove.

[0013] Furthermore, the support frame body has multiple through holes on its uprights, and positioning pins are provided below the upper and lower support plates. The upper and lower support plates are supported by the positioning pins cooperating with the through holes.

[0014] The beneficial effects of this utility model are:

[0015] The wedge blocks are inserted into the gap between the support shaft and the center hole of the cable reel to complete the positioning. The three sets of evenly arranged wedge blocks can effectively fix the support shaft and the center hole of the cable reel on the same axis, ensuring that the cable reel can drive the support shaft to rotate concentrically.

[0016] The slot is equipped with a universal ball bearing. When the cable is laid out, it will drive the cable reel to rotate, which in turn will drive the support shaft, which is fixed together by the limit locking assembly, to rotate synchronously. The support shaft can be kept rotating by the universal ball bearing, reducing friction. At the same time, multiple evenly arranged universal ball bearings help to distribute the weight of the support shaft and the cable reel, ensuring that the support shaft can rotate normally.

[0017] After the clamp is fixed, the nut and screw can ensure that the wedge block will not move in the axial direction of the support shaft, thereby locking the cable reel in the axial direction. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1-4 This utility model provides a technical solution:

[0025] like Figures 1-4 As shown, a cable support frame includes a support shaft 3, two sets of symmetrically arranged support frame bodies 2, and a jack 4 located on the support frame bodies 2. The upper and lower ends of the jack 4 are respectively provided with an upper support plate 41 and a lower support plate 42. The upper support plate 41 and the lower support plate 42 are slidably connected to the columns of the support frame bodies 2. The upper support plate 41 is provided with a slot 43 for placing the support shaft 3, and a universal ball bearing 44 is provided in the slot 43. Two sets of limiting locking components 5 are provided on the support shaft 3 near the center hole of the cable reel 1. The limiting locking components 5 include clamps 51 and wedge blocks 53. The three sets of wedge blocks 53 are evenly arrayed on the circumference of the clamps 51.

[0026] With the above technical solution, when the cable reel 1 is on the ground, the support shaft 3 is inserted into the center hole of the cable reel 1. Since there is still a certain gap between the support shaft 3 and the cable reel 1, two sets of limiting and locking components 5 are installed at both ends of the cable reel 1. The clamps 51 are used to fix them to the support shaft 3. At the same time, the wedge blocks 53 are inserted into the gap between the support shaft 3 and the center hole of the cable reel 1 to complete the limiting. The three sets of evenly arranged wedge blocks 53 can effectively fix the support shaft 3 and the center hole of the cable reel 1 on the same axis, ensuring that the cable reel 1 can drive the support shaft 3 to rotate concentrically. After the wedge blocks 53 are installed in place, the two sets of support frame bodies 2 are moved to both sides of the support shaft 3 so that the support shaft 3 can be placed in the slot 43. After the support frame bodies 2 are fixed, the support shaft 3 and the cable reel 1 are lifted by the jack 4, so that the bottom of the cable reel 1 is lifted off the ground. Since the slot 43 is equipped with a universal ball bearing 44, when the cable is laid out, it will drive the cable reel 1 to rotate, which in turn will drive the support shaft 3, which is fixed as one piece by the limit locking assembly 5, to rotate synchronously. The support shaft 3 can be kept rotating by the universal ball bearing 44 to reduce friction. At the same time, the multiple evenly arranged universal ball bearings 44 help to distribute the weight of the support shaft 3 and the cable reel 1, ensuring that the support shaft 3 can rotate normally.

[0027] Furthermore, the clamp 51 has a segmented structure. After the support shaft 3 passes through the central hole, the segmented clamp 51 is installed onto the support shaft 3, and then the clamp 51 is locked with bolts 52 to fix the clamp 51 to the support shaft 3. The clamp 51 structure facilitates the initial passage of the support shaft 3 through the central hole.

[0028] Furthermore, a support block 55 and a screw 54 are provided between the clamp 51 and the wedge block 53. The support block 55 is fixed on the clamp 51, and the screw 54 passes through the support block 55 and connects to the large end of the wedge block 53.

[0029] Through the above technical solution, the moving screw 54 moves horizontally on the support block 55, which in turn drives the wedge block 53 to move. The wedge block 53 extends out of the clamp 51, and the bottom of the wedge block 53 is located on the support shaft 3, which facilitates the insertion of the wedge block 53 between the support shaft 3 and the center hole of the cable reel 1. If necessary, the wedge block 53 can be inserted between the center hole and the support shaft 3 by tapping one end of the screw 54, thereby improving the wedge tightening effect.

[0030] Furthermore, the screw 54 is provided with a matching nut 56, which is located between the support block 55 and the wedge block 53.

[0031] Through the above technical solution, the nut 56 can abut against the support block 55, preventing the cable reel 1 from throwing out the wedge block 53 after rotation, ensuring that the wedge block 53 is always between the center hole and the round shaft, improving the wedging effect, and making the cable reel 1 and the round shaft connected as one unit so that they can rotate easily. At the same time, after the clamp 51 is fixed, the nut 56 and the screw 54 can ensure that the wedge block 53 will not move in the axial direction of the support shaft 3, thereby locking the cable reel 1 in the axial direction.

[0032] Furthermore, the slot 43 is semi-circular, and multiple universal ball bearings 44 are evenly arranged radially along the circular slot. At the same time, multiple rows of universal ball bearings 44 can be arranged in the slot 43 to further distribute the weight borne by a single universal ball bearing 44, improve support stability, and ensure that the support shaft 3 can rotate effectively.

[0033] Furthermore, the support frame body 2 has multiple through holes 21 on its uprights, and positioning pins are provided below the upper support plate 41 and the lower support plate 42. The upper support plate 41 and the lower support plate 42 are supported by the positioning pins cooperating with the through holes 21.

[0034] Through the above technical solution, the lower ends of the upper support plate 41 and the lower support plate 42 are supported by the cooperation of the positioning pin and the through hole 21, so as to prevent the upper support plate 41 and the lower support plate 42 from slipping.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
