Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically a stringing device for power engineering construction. Background Technology

[0002] In the field of power engineering construction, overhead line stringing equipment is an indispensable key device, and its performance directly affects the efficiency and quality of power line laying. With the continuous growth of electricity demand and the expanding scale of power engineering construction, higher requirements are placed on the functionality and practicality of overhead line stringing equipment.

[0003] However, the widely used power engineering construction stringing equipment currently has significant shortcomings: First, the equipment generally lacks a wire cutting mechanism. If construction workers need to adjust the length of the wire according to actual needs during the stringing process, they can only carry a separate cutting tool to cut it. Second, when workers cut the cable midway, the reel will rotate in the opposite direction due to inertia, rewinding the cable. This makes the cable on the reel loose. When pulling the cable again, construction workers need to expend a lot of effort to tighten the loose cable back to a state that fits the reel. The whole process is cumbersome and laborious, which greatly reduces construction efficiency and increases the labor intensity of construction workers.

[0004] Therefore, developing a new type of power engineering construction stringing device with wire cutting function and effective avoidance of cable slack after cutting has become an important issue that urgently needs to be addressed in the current power engineering construction field. Utility Model Content

[0005] The purpose of this utility model is to provide a power line overhead device for power engineering construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cable-laying device for power engineering construction includes a mobile frame with a reel rotatably mounted on it. The reel is driven by a motor mounted on the mobile frame and has a cable wound on it. A mounting frame is also provided at the front end of the reel on the mobile frame. The mounting frame has a through hole for the cable to pass through, and a cutting mechanism is provided on one side of the mounting frame at the through hole, while a fixing mechanism is provided on the other side. The cutting mechanism includes a fixing plate, a cutting blade, and a drive assembly. The fixing plate is fixedly mounted on the side of the mounting frame and has a rectangular notch. The cutting blade is slidably disposed within the rectangular notch, and the drive assembly provides power for the cutting blade to move up and down. The fixing mechanism includes a support plate, a pressure plate, and a screw. The support plate is fixedly disposed within the mounting frame and below the through hole, while the pressure plate is movably disposed within the mounting frame and above the through hole. The adjacent surfaces of the pressure plate and the support plate are symmetrically provided with arc-shaped grooves. A screw is rotatably mounted on the top surface of the pressure plate, and the screw is threaded onto the mounting frame. A knob is also installed at the top of the screw.

[0008] As a further embodiment of this utility model: the drive assembly includes a fixed base, a connecting rod, and a pressure rod. The mounting bracket is also fixedly provided above the rectangular notch. The pressure rod is rotatably mounted on the fixed base via a mounting shaft. Return torsion springs are symmetrically installed at both ends of the mounting shaft. The pressure rod is connected to the cutting blade via a connecting rod, wherein the two ends of the connecting rod are hinged to the pressure rod and the cutting blade, respectively.

[0009] As a further embodiment of this utility model: the top surface of the support plate is also fixedly provided with multiple guide rods, and the pressure plate is movably mounted on the multiple guide rods.

[0010] As a further embodiment of this utility model: the mounting bracket is movably mounted on the mobile frame, and the mobile frame is also provided with a power component for driving the mounting bracket to reciprocate horizontally. The power component includes a reciprocating screw rotatably mounted below the mobile frame and a reciprocating moving part mounted on the reciprocating screw. The reciprocating moving part is fixedly mounted on the bottom surface of the mounting bracket, and the mobile frame is provided with a strip-shaped hole for the reciprocating moving part to slide.

[0011] As a further embodiment of this utility model: the reciprocating moving component is connected to the reel via a pulley drive assembly.

[0012] As a further embodiment of this utility model: a gantry frame is also fixedly installed on the mobile frame, the mounting bracket is movably installed inside the gantry frame, and a sliding hole for the screw to slide is also provided on the top surface of the gantry frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cutting mechanism of this utility model can directly cut cables without requiring construction personnel to carry additional cutting tools, thus improving construction convenience; the fixing mechanism drives the screw by rotating the knob, so that the pressure plate and the support plate cooperate, and the cable is clamped by the arc groove. When cutting the cable, it prevents the cable reel from rotating in the opposite direction and causing the cable to loosen, which solves the problems of existing devices and improves construction efficiency and safety.

[0015] 2. When the motor drives the reel to rotate and release the wire, the reciprocating screw in the power assembly drives the reciprocating moving parts, causing the mounting frame to move horizontally back and forth. This design ensures that the cable passing through the through hole can always be transported in a straight line, avoiding problems such as bending and tangling of the cable due to pulling, ensuring the smoothness of the wire laying process, and further improving construction efficiency.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Example 1

[0023] Please see Figure 1-4A wire-laying device for power engineering construction includes a mobile frame 1, on which a reel 2 is rotatably mounted. The reel 2 is driven by a motor 3 mounted on the mobile frame 1, and a cable 4 is wound on the reel 2. A mounting frame 5 is also provided at the front end of the reel 2 on the mobile frame 1. The mounting frame 5 has a through hole 6 for the cable 4 to pass through, and a cutting mechanism is provided on one side of the mounting frame 5 at the through hole 6, and a fixing mechanism is provided on the other side.

[0024] The cutting mechanism includes a fixed plate 7, a cutting blade 9, and a drive assembly. The fixed plate 7 is fixedly installed on the side of the mounting bracket 5, and a rectangular notch 8 is provided on the fixed plate 7. The cutting blade 9 is slidably disposed in the rectangular notch 8. The drive assembly is used to provide power for the cutting blade 9 to move up and down. The cutting mechanism can directly cut the cable 4 without requiring construction personnel to carry additional cutting tools, thus improving the convenience of construction.

[0025] The fixing mechanism includes a support plate 10, a pressure plate 11, and a screw 12. The support plate 10 is fixedly installed in the mounting frame 5 and located below the through hole 6. The pressure plate 11 is movably installed in the mounting frame 5 and located above the through hole 6. The adjacent surfaces of the pressure plate 11 and the support plate 10 are symmetrically provided with arc-shaped grooves. The top surface of the pressure plate 11 is also rotatably mounted with a screw 12. The screw 12 is threaded onto the mounting frame 5, and a knob 13 is also installed at the top of the screw 12. The fixing mechanism drives the screw 12 by rotating the knob 13, so that the pressure plate 11 cooperates with the support plate 10. The arc-shaped groove clamps the cable 4, preventing the cable spool from rotating in the opposite direction and causing the cable 4 to loosen when the cable 4 is cut. This solves the problems existing in the current device and improves construction efficiency and safety.

[0026] The drive assembly includes a fixed base 14, a connecting rod 15, and a pressure rod 16. The mounting bracket 5 is also fixedly mounted on the fixed base 14 above the rectangular notch 8. The pressure rod 16 is rotatably mounted on the fixed base 14 via a mounting shaft 17. Return torsion springs are symmetrically mounted at both ends of the mounting shaft 17. The pressure rod 16 is connected to the cutting blade 9 via the connecting rod 15. The two ends of the connecting rod 15 are hinged to the pressure rod 16 and the cutting blade 9, respectively. Pressing down the pressure rod 16 causes the cutting blade 9 to move downward within the rectangular notch 8 via the connecting rod 15, thereby cutting the cable 4. The return torsion springs automatically reset the pressure rod 16 after cutting, facilitating the next operation. This drive assembly has a simple structure, is easy to operate, and can stably provide power to the cutting blade 9, ensuring smooth cutting.

[0027] In addition, a plurality of guide rods 18 are fixedly provided on the top surface of the support plate 10. The pressure plate 11 is movably mounted on the plurality of guide rods 18. The guide rods 18 provide guidance for the movement of the pressure plate 11, ensuring that the pressure plate 11 remains stable during the up and down movement and does not deviate. This allows the pressure plate 11 to be accurately aligned with the arc groove on the support plate 10, thereby better clamping the cable 4 and enhancing the stability and reliability of the fixing mechanism.

[0028] Example 2

[0029] This embodiment is an improvement on embodiment 1, specifically as follows:

[0030] Please see Figure 1 and Figure 2 The mounting frame 5 is movably mounted on the mobile frame 1. The mobile frame 1 is also equipped with a power assembly that drives the mounting frame 5 to reciprocate horizontally. The power assembly includes a reciprocating screw 19 rotatably mounted below the mobile frame 1 and a reciprocating moving part 20 mounted on the reciprocating screw 19. The reciprocating moving part 20 is fixedly mounted on the bottom surface of the mounting frame 5. The mobile frame 1 has a strip-shaped hole for the reciprocating moving part 20 to slide. When the motor 3 drives the reel 2 to rotate and unload the cable, the reciprocating screw 19 in the power assembly drives the reciprocating moving part 20, causing the mounting frame 5 to reciprocate horizontally. This design ensures that the cable 4 passing through the through hole 6 can always be transported in a straight line, avoiding problems such as bending and tangling of the cable 4 due to pulling, ensuring the smoothness of the cable laying process, and further improving construction efficiency.

[0031] Preferably, the reciprocating moving part 20 is connected to the reel 2 via a pulley drive group 21. The pulley drive group 21 connects the rotation of the reel 2 with the movement of the reciprocating moving part 20, realizing the effective transmission of power. This allows the horizontal reciprocating motion of the mounting frame 5 to be synchronized with the unloading action of the reel 2, eliminating the need for an additional power source, simplifying the device structure, and ensuring the coordination of the operation of each component.

[0032] In addition, a gantry frame 22 is fixedly installed on the mobile frame 1, and the mounting frame 5 is movably installed inside the gantry frame 22. The top surface of the gantry frame 22 is also provided with a sliding hole 23 for the screw 12 to slide. The gantry frame 22 provides stable support and movement space for the horizontal reciprocating movement of the mounting frame 5, ensuring that the mounting frame 5 remains stable during the horizontal reciprocating movement.

[0033] Working principle:

[0034] During construction, motor 3 drives reel 2 to rotate and release cable 4. Cable 4 passes through through hole 6 of mounting frame 5. At the same time, reel 2 drives reciprocating screw 19 to rotate through pulley transmission group 21, so that reciprocating moving part 20 and mounting frame 5 move horizontally back and forth in gantry frame 22 to ensure that cable 4 is transported in a straight line.

[0035] When it is necessary to cut the cable 4, turn the knob 13 of the fixing mechanism, and the screw 12 will drive the pressure plate 11 to move downward. The cable 4 will be clamped by the arc groove. Then, the pressure rod 16 of the cutting mechanism will be pressed down, and the cutting blade 9 will move downward through the connecting rod 15 to complete the cutting of the cable 4. After the cutting is completed, the return torsion spring will reset the pressure rod 16. Turn the knob 13 in the opposite direction to release the pressure plate 11 and continue the cable laying operation.

[0036] The entire overhead line device, through the coordinated work of its components, enables the smooth transport, convenient cutting, and effective fixing of cable 4, solving the problems existing in the current overhead line device and improving the efficiency and safety of power engineering construction.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
