Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, specifically relating to a mobile frame for laying electromechanical cables. Background Technology

[0002] A cable laying rack is a device used for supporting, laying, and moving cables. It is mainly used in power and telecommunications projects. A suitable laying rack can be selected based on the diameter and tonnage of the cable reel, ensuring that the cable is not damaged or tangled during installation.

[0003] In existing technologies, cable reeling frames commonly used to support electromechanical cables require placing the cable roll between two reeling frames. The two frames are then brought close together and supported on both sides of the cable roll, and the cable roll is lifted upwards using jacks. During this process, the two reeling frames need to be manually moved closer together, and after use, they need to be moved apart. This repeated operation of the two reeling frames is not only cumbersome, but the two separate reeling frames also make it difficult to guarantee the stability of the cable reeling process. The relative displacement of the two reeling frames during unwinding can easily occur, affecting the stability of the cable reeling. Utility Model Content

[0004] To address the problems of existing cable unwinding frames, which require manual maneuvering to bring the two frames closer together and then moving them apart after use, this invention provides an electromechanical cable unwinding moving frame. This frame employs an integrated support system, providing support for the unwinding roll while ensuring stability during the unwinding process. Furthermore, the integrated design eliminates the need for frequent maneuvering to bring the two support frames closer together or further apart, saving unnecessary steps. The specific technical solution is as follows:

[0005] A mobile frame for laying out electromechanical cables includes a base frame, the base frame being U-shaped with its opening facing forward, and two sets of support components symmetrically arranged on the base frame.

[0006] Each set of the support components includes a support arm fixedly and vertically mounted on the base frame. The support arm is hook-shaped, and a clearance groove is provided on the rear side wall of the support arm. A support portion is horizontally arranged at the free end of the top of the support arm. The support portion is horizontally arranged with the base frame. A mounting seat is installed on the side wall of the support arm. A rotating shaft is rotatably connected inside the mounting seat. One end of the rotating shaft extends out of the mounting seat and is equipped with a coil spring. The two ends of the coil spring are respectively connected to the mounting seat and the rotating shaft. A bracket is fixedly mounted on the rotating shaft. Rollers are symmetrically connected to the bracket and rotatably connected to it. An extension block is installed on the end of the bracket near the support portion, and the extension block rotatably rests on the support portion.

[0007] In the above technical solution, the clearance groove is disposed on the rotation path of the roller.

[0008] In the above technical solution, a drive assembly is provided on the rear side of the base frame;

[0009] The drive assembly includes a mounting platform fixedly installed on the rear side wall of the base frame. A cylinder is mounted on the mounting platform, and the output end of the cylinder is connected to a drive frame. The drive frame is U-shaped.

[0010] In the above technical solution, the base frame is symmetrically equipped with two sets of lifting components on the left and right sides;

[0011] The lifting assembly includes a fixed cylinder that is fixed and vertically installed on the base frame. The outer wall of the fixed cylinder has a groove. A lifting column is slidably embedded inside the fixed cylinder. A movable pin is installed at the bottom of the side wall of the lifting column. One end of a drive rod is rotatably connected to the movable pin. The other end of the drive rod is rotatably connected to the free end of the drive frame. A support plate is installed at the top of the lifting column.

[0012] In the above technical solution, the tray is configured as an upwardly curved arc.

[0013] In the above technical solution, the lifting component is disposed on the outside of the supporting component.

[0014] In the above technical solution, the pallet supports a roller, and the roller is provided with a wire unwinding coil.

[0015] In the above technical solution, a reinforcing rod is installed obliquely on the rear side wall of the support arm, and the two ends of the reinforcing rod are respectively connected to the support arm and the base frame.

[0016] The advantages of this utility model for a mobile cable laying rack compared to existing technologies are as follows:

[0017] I. Existing cable feeding frames require manual adjustment of the two feeding frames to bring them closer together and then move them apart after use. This repetitive operation is cumbersome, and the separate nature of the two frames makes it difficult to ensure stability during the feeding process. The frames are prone to relative displacement during unwinding, affecting the stability of the cable feeding. This invention addresses this problem by using an integrated base frame with two support arms. The support arms, along with brackets, rollers, extension blocks, and bearings, provide support for the rollers. Compared to the traditional separate support system where two sets of feeding frames are brought closer together, this integrated support system provides support for the cable roll while ensuring stability during feeding. Furthermore, it eliminates the need for frequent adjustments of the two support frames, saving unnecessary steps.

[0018] Second, in this utility model, the cylinder and drive frame can drive the two sets of pallets on both sides to move upward synchronously. There is no need to operate the pallets one by one on each side to lift them. That is, the same driving force can be used to lift the two sets of pallets synchronously to support the roller. Compared with the traditional method of setting jacks on both sides and operating them separately, it is faster and more effective to lift the unwinding coil into place.

[0019] Third, this utility model adopts the cooperation of mounting base, rotating shaft and coil spring, which can drive the bracket to rotate automatically when the roller enters the inner cavity of the support arm, and automatically make way for the roller after the roller on the bracket rotates into the clearance groove. When the roller enters the clearance groove, the bracket automatically returns to the initial position, realizing the rolling support of the roller by the two sets of rollers at the bracket.

[0020] Fourth, by setting two sets of rollers at corresponding positions, this utility model can provide rolling support for the roller, ensuring that the roller can roll relative to the rollers when unwinding;

[0021] In summary, compared to the traditional method of using two separate sets of support frames that are close to each other for support, this utility model adopts an integrated support method. While providing support for the wire roll, the integrated design can better ensure the stability during the wire roll feeding process. It also eliminates the need for frequent operation of moving the two support frames closer or further apart, saving unnecessary operation steps. Using the same driving force, the two sets of pallets can be lifted synchronously to support the roller. Compared to the traditional method of setting jacks on both sides and operating them separately, it is faster and more effective to lift the wire roll into place. Attached Figure Description

Detailed Implementation

[0028] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] See Figures 1 to 5 As shown, a mobile frame for laying out electromechanical cables includes a base frame 1. The base frame 1 is U-shaped and the opening of the base frame 1 faces forward, so that the cable roll can be rolled and placed in the inner cavity of the base frame 1, which facilitates the subsequent support, lifting and unwinding of the cable roll. Two sets of support components are symmetrically arranged on the left and right sides of the base frame 1.

[0030] Main references Figures 2 to 5 As shown, each support assembly includes a support arm 2 fixed and vertically installed on the base frame 1. The support arm 2 is hook-shaped. A clearance groove 3 is provided on the rear side wall of the support arm 2. A support part 4 is horizontally provided at the free end of the top of the support arm 2. The support part 4 is horizontally provided with the base frame 1. A mounting seat 5 is installed on the side wall of the support arm 2. A rotating shaft 6 is rotatably connected inside the mounting seat 5. One end of the rotating shaft 6 extends out of the mounting seat 5 and is equipped with a coil spring 7. The two ends of the coil spring 7 are respectively connected to the mounting seat 5 and the rotating shaft 6. A bracket 8 is fixedly installed on the rotating shaft 6. Rollers 9 are symmetrically connected to the bracket 8 and rotated. An extension block 10 is installed at the end of the bracket 8 near the support part 4, and the extension block 10 is rotatably mounted on the support part 4.

[0031] When the cable roll moves upward, it first drives the bracket 8 to rotate towards the relief groove 3, so that the roller 9 is embedded into the inner cavity of the relief groove 3. At this time, the coil spring 7 is forced to deform elastically to avoid the cable roll entering the inner cavity of the support arm 2. When the cable roll is completely inside the inner cavity at the top of the support arm 2, the external force on the bracket 8 is removed. Under the elastic force of the coil spring 7, the rotating shaft 6 causes the bracket 8 to return to the horizontal position, that is, the roller 9 is disengaged from the inner cavity of the relief groove 3 and returns to the horizontal state. At this time, the extension block 10 is placed at the support part 4 to relatively close the space at the top of the support arm 2. Then the cable roll is lowered to the roller 9 to support the cable roll.

[0032] To ensure that the rotating roller 9 has enough space to allow the cable coil to rise to the inner cavity of the top of the support arm 2, the clearance groove 3 is set on the rotation path of the roller 9. This ensures that the rotating bracket 8 causes the roller 9 to be fully embedded in the inner cavity of the clearance groove 3, which facilitates the cable coil to enter the inner cavity of the top of the support arm 2.

[0033] Main references Figures 2 to 4 As shown, a drive assembly is provided on the rear side of the base frame 1; the drive assembly includes a mounting platform 12 fixedly installed on the rear side wall of the base frame 1, a cylinder 13 is mounted on the mounting platform 12, and a drive frame 14 is connected to the output end of the cylinder 13. The drive frame 14 is U-shaped, and the drive frame 14 can be moved in the forward and backward direction by the opening of the cylinder 13; two sets of lifting assemblies are symmetrically arranged on the left and right sides of the base frame 1; the lifting assembly includes a fixed cylinder 17 fixedly and vertically installed on the base frame 1, a groove 18 is opened on the outer side wall of the fixed cylinder 17, a lifting column 19 is slidably embedded in the fixed cylinder 17, a moving pin 16 is installed at the bottom end of the side wall of the lifting column 19, and a drive rod 15 is rotatably connected to the moving pin 16 through a pin shaft. One end of the drive rod 15 is rotatably connected to the free end of the drive frame 14 via a pin. The top of the lifting column 19 is equipped with a support plate 20. The drive frame 14 is driven to move forward by the opened cylinder 13, which in turn causes the drive frame 14 to drive one end of the two drive rods 15 to move synchronously, so that the moving pin 16 at the other end of the drive rod 15 moves upward along the inner cavity of the groove 18, causing the lifting column 19 and the support plate 20 to move upward synchronously. The support plate 20 supports a roller 22, and a wire unwinding coil 21 is provided on the roller 22. The support plate 20 is set to be curved upward so as to fit the lower surface of the roller 22 better, and the arc-shaped sidewall of the support plate 20 provides more stable support for the roller 22.

[0034] In addition, the lifting component is located on the outside of the support component. The lifting component lifts the roller 22, allowing the roller 22 to be placed inside the support component. Since the lifting component is located on the outside of the support component, it will not occupy the space inside the base frame 1, leaving enough space for the unwinding coil 21 to enter the inner cavity of the base frame 1, which is more in line with the usage requirements.

[0035] In addition, see Figure 2 As shown, a reinforcing rod 11 is installed obliquely on the rear side wall of the support arm 2, and the two ends of the reinforcing rod 11 are connected to the support arm 2 and the base frame 1 respectively. With the help of the reinforcing rod 11, the connection between the support arm 2 and the base frame 1 can be further reinforced to ensure the stability of the overall equipment when supporting and lifting the roller 22.

[0036] It is worth noting that the cylinder 13 used in this application is a commonly used self-locking cylinder on the market, whose output end can stay at any position and be locked; the model of the above-mentioned existing components will not be limited or described in detail here.

[0037] The working principle of the electromechanical cable laying mobile frame in this embodiment is as follows:

[0038] The unwinding coil 21 and roller 22 are rolled into the base frame 1, so that roller 22 is above the support plate 20. The activated cylinder 13 drives the drive frame 14 to move forward, which in turn drives one end of the two drive rods 15 to move synchronously. This causes the moving pin 16 at the other end of the drive rod 15 to move upward along the inner cavity of the groove 18, causing the lifting column 19 and support plate 20 to move upward synchronously until the support plate 20 is in contact with the bottom of roller 22 and continues to move upward. This causes roller 22 to gradually push the lower surface of the support 8 and causes the support 8 to rotate around the pivot 6. At this time, the coil spring 7 is forced to undergo elastic deformation, causing the roller 9 on the support 8 to rotate into the inner cavity of the relief groove 3. At this time, the roller 22, which continues to move upward, enters the support. In the inner cavity at the top of arm 2, roller 22 disengages from the drive of bracket 8. Under the elastic force of coil spring 7, bracket 8 rotates back to its original horizontal position. At this time, extension block 10 is placed on support part 4. With the help of extension block 10, bracket 8 and support arm 2, a relatively closed space is formed at the top of support arm 2. Then, with the help of the output end of cylinder 13 moving to the rear, the drive rod 15 drives the moving pin 16, lifting column 19, support plate 20 and roller 22 supported on support plate 20 to move down synchronously until roller 22 descends to fit the outer wall of roller 9. At this time, roller 22 completes the up-down movement trajectory in the inner cavity at the top of support arm 2 and completes the rolling placement at the left and right sets of rollers 9 to ensure that the subsequent unwinding coil 21 can rotate without restriction.

[0039] Compared to the traditional method of using two separate sets of support frames that are close to each other for support, this utility model adopts an integrated support method. While providing support for the wire roll 21, the integrated design can better ensure the stability during the wire feeding process. It also eliminates the need for frequent operation of moving the two support frames closer or further apart, saving unnecessary operation steps. Using the same driving force, the two sets of pallets 20 can be lifted synchronously to support the roller 22. Compared to the traditional method of setting jacks on both sides and operating them separately, it is faster and more effective to lift the wire roll 21 into place.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
