Description

Technical Field

[0001] The utility model relates to the technical field of cable conveying, in particular to a cable conveying mechanism for power engineering construction. Background Art

[0002] With the development of the economy, the scale of the power grid is constantly expanding. During the construction of power projects, the laying of power cables is particularly important, which is directly related to the safe operation of the power grid.

[0003] The prior art such as the one with the publication number: CN220148833U discloses a cable conveying mechanism for power engineering construction, which includes a base and two conveying units arranged in a "V" - shaped structure on the base. The conveying unit includes a bracket and a transmission roller; the bracket is in a "C" - shaped structure, including a bottom plate and side plates arranged in parallel on both sides of the bottom plate. The utility model provides a cable conveying mechanism for power engineering construction, which has a simple structure, is easy to operate, and can automatically adapt to different specifications of cables.

[0004] To sum up, in the process of installation and use at the user end, the current cable conveying mechanism still has the following defects: when conveying the cable, a pressure roller is used to press and limit the cable from the top of the cable. The pressure roller adjusts the longitudinal height of the pressure roller by means of bolts, that is, the pressure roller is pressed against the outer wall surface of the cable. There is no buffer between them, which easily causes the cable to be pressed between the two side conveyor belts. Under the action of the self - weight of the cable, the cable will be more tightly pressed between the two side conveyor belts, resulting in an increase in the tightness of the conveyor belt and too large friction, which makes the cable conveying not smooth enough. Summary of the Utility Model

[0005] In order to overcome the defects of the above - mentioned prior art pointed out, the inventor of the present invention has conducted in - depth research and completed the present utility model after a large amount of creative labor.

[0006] Specifically, the technical problem to be solved by the present utility model is: to provide a cable conveying mechanism for power engineering construction to solve the technical problem that when conveying the cable, a pressure roller is used to press and limit the cable from the top of the cable. The pressure roller adjusts the longitudinal height of the pressure roller by means of bolts, that is, the pressure roller is pressed against the outer wall surface of the cable. There is no buffer between them, which easily causes the cable to be pressed between the two side conveyor belts. Under the action of the self - weight of the cable, the cable will be more tightly pressed between the two side conveyor belts, resulting in an increase in the tightness of the conveyor belt and too large friction, which makes the cable conveying not smooth enough.

[0007] To solve the above - mentioned technical problem, the present utility model provides the following technical solution:

[0008] A cable conveying mechanism for electric power engineering construction, including a hollow frame. At the upper position on one side of the hollow frame, a pipe inlet groove is provided. Inside the hollow frame, two feeding components are symmetrically installed. On the top of the hollow frame, a pressing component is installed, and the pressing end of the pressing component is located inside the hollow frame and between the two feeding components. A conveying cavity for pressing and conveying the cable is formed between the two feeding components and the pressing end of the pressing component;

[0009] The pressing component includes an electric telescopic rod installed on the top of the hollow frame. The movable end of the electric telescopic rod is fixedly connected with a lifting plate. Four corners of the top of the lifting plate are provided with sliding holes, and the lifting plate is slidably connected with T-shaped rods through the sliding holes. Between the bottoms of the two T-shaped rods on the same side, a U-shaped frame is welded. A spring is sleeved between the rod ends of the T-shaped rods and between the opposite surfaces of the U-shaped frame and the lifting plate.

Inside the roller frame, a supporting roller is rotatably installed. At the top of the roller frame, a driving motor I for driving the supporting roller to rotate is installed, and the driving end of the driving motor I is connected to the top end of the supporting roller.

[0012] As an improved technical solution, the two supporting rollers are arranged in a "V" shape.

[0013] As an improved technical solution, the feeding component further includes two moving frames slidably installed inside the hollow frame, and the roller frame is welded to the top end of the moving frame.

[0028] As Figures 1 to 3 As commonly shown, the present invention provides a cable conveying mechanism for electric power engineering construction, which includes a hollow frame 1 and universal wheels installed at the four corners of the bottom of the hollow frame 1. An inlet pipe groove 11 is provided at a position above one side of the hollow frame 1. The cable is placed between two feeding components 2 through the inlet pipe groove 11. The cable is located between two side rollers 24. Two feeding components 2 are symmetrically installed inside the hollow frame 1. A pressing component 3 is installed at the top of the hollow frame 1, and the pressing end of the pressing component 3 is located inside the hollow frame 1 and between the two feeding components 2. A conveying cavity for pressing and conveying the cable is formed between the two feeding components 2 and the pressing end of the pressing component 3.

[0029] The pressure component 3 includes an electric telescopic rod 31 installed on the top of the hollow frame 1, and the movable end of the electric telescopic rod 31 is located inside the hollow frame 1. The movable end of the electric telescopic rod 31 is fixedly connected to a lifting plate 32. Four corners of the top of the lifting plate 32 are each provided with a sliding hole, and the lifting plate 32 is slidably connected with a T-shaped rod 33 through the sliding holes. A U-shaped frame 35 is welded between the bottoms of two T-shaped rods 33 on the same side. A spring 34 is sleeved between the rod end of the T-shaped rod 33 and the opposite surfaces of the U-shaped frame 35 and the lifting plate 32. A pressure roller 36 is rotatably installed in the inner cavity of the U-shaped frame 35. When the electric telescopic rod 31 extends, it drives the lifting plate 32 to move downward, so that the outer wall surface of the pressure roller 36 contacts the outer wall surface of the cable. When the pressure roller 36 contacts the cable, the pressure roller 36 is stressed by the contact with the cable, which will drive the U-shaped frame 35 to move the T-shaped rod 33 upward and compress the spring 34. The longitudinal height of the pressure roller 36 is adjustable to ensure that cables of different sizes can be pressed from its top.

[0030] In a cable conveying mechanism for electric power engineering construction according to an embodiment of the present invention, the supporting roller 24 is made of a hard material. When the cable contacts the supporting roller 24, the supporting roller 24 will not be deformed due to the contact with the cable. At the same time, the pressure roller 36 compresses the cable from the top. When the cable applies an upward force to the pressure roller 36, the U-shaped frame 35 moves upward to compress the spring 34, so that the cable and the pressure roller 36 are in elastic contact to ensure the smoothness of cable conveying.

[0031] As Figure 1 shown, in this embodiment, triangular support blocks 12 are welded to the front and rear sides of the top of the inner cavity of the hollow frame 1, and the pressure component 3 is located between the two triangular support blocks 12. The triangular support blocks 12 are used to support the top of the hollow frame 1.

[0032] As Figures 1 to 2 collectively shown, in this embodiment, the feeding component 2 includes two roller frames 22 arranged oppositely, and the distance between the two feeding components 2 is adjustable. The distance between the two supporting rollers 24 on both sides is adjustable, so that it can further adapt to more sizes of cables for clamping and conveying, with high adaptability and strong flexibility. A supporting roller 24 is rotatably installed inside the roller frame 22. The supporting roller 24 is made of a hard material. When the cable contacts the supporting roller 24, the supporting roller 24 will not be deformed due to the contact with the cable. A driving motor one 23 for driving the supporting roller 24 to rotate is installed at the top end of the roller frame 22, and the driving end of the driving motor one 23 is connected to the top end of the supporting roller 24.

[0033] As Figures 1 to 2 collectively shown, in this embodiment, the two supporting rollers 24 on both sides are arranged in a "V" shape, and the "V" shape formed by the two supporting rollers 24 on both sides is adapted to clamp and convey cables of different sizes.

[0034] As Figures 1 to 2As shown together, in this embodiment, the feeding component 2 further includes two moving frames 21 slidably installed inside the hollow frame 1, and the roller frame 22 is welded to the top of the moving frame 21. Transmission blocks 27 are provided on both sides of the bottom of the moving frame 21. Two T-shaped chutes are provided on one side of the transmission block 27. A T-shaped support block 28 is slidably installed between the two transmission blocks 27 through the T-shaped chutes thereon, and the T-shaped support block 28 is fixed inside the hollow frame 1.

[0035] As Figures 1 to 2 As shown together, in this embodiment, a threaded hole is provided on one side of the transmission block 27. A bidirectional lead screw 29 is threadedly installed through the threaded hole provided thereon. The two ends of the bidirectional lead screw 29 are respectively rotatably installed on both sides of the inner wall of the hollow frame 1 through bearings. A drive source for driving the bidirectional lead screw 29 to rotate is installed on the hollow frame 1.

[0036] As Figures 1 to 2 As shown together, in this embodiment, the drive source includes a second drive motor 25 installed inside the hollow frame 1. A synchronous belt assembly 26 is installed between the drive end of the second drive motor 25 and the bidirectional lead screw 29. The synchronous belt assembly 26 consists of two synchronous pulleys and a synchronous belt installed between the two synchronous pulleys. The synchronous belt assembly 26 is a mature existing technology and will not be elaborated herein.

[0037] The process of adjusting the distance between the two side rollers 24 is as follows:

[0038] The second drive motor 25 drives the bidirectional lead screw 29 to rotate through the synchronous belt assembly 26. Under the threaded drive of the bidirectional lead screw 29 and the threaded hole on the transmission block 27, the distance between the two side rollers 24 is adjusted under the forward and reverse rotation of the bidirectional lead screw 29. The adjustment method is simple and fast.
