Abstract
Description
Technical Field
[0001] The present invention relates to power engineering construction equipment, and particularly to a wire laying device for power engineering lines. Background Art
[0002] In power engineering construction, wire laying is a crucial link, and its efficiency and quality directly affect the overall project progress and power supply stability.
[0003] Traditional wire laying devices for power engineering lines have many drawbacks. In early wire laying equipment, the wire winding method was simple, and the wire reel lacked effective locking and unlocking mechanisms. During wire laying, the wire reel was prone to reverse rotation due to accidental external forces, resulting in chaotic wire winding. This not only seriously affected the wire laying efficiency but also might cause wire abrasion, reducing the service life of the wire and increasing potential hazards in power transmission. Moreover, it was extremely inconvenient to adjust the guiding position of the wire for these devices. Usually, they could only be applied to relatively regular and single wire laying environments. Once encountering construction scenarios with complex terrains and variable wire routes, it was difficult to flexibly adjust the guiding angle of the wire. Construction workers often needed to spend a lot of time manually adjusting the wire route, and the operation process was cumbersome and had low accuracy, greatly restricting the overall progress of the wire laying work.
[0004] In addition, the coordination between components of traditional wire laying devices was poor, and the overall structural stability was insufficient. During long-term and high-intensity wire laying operations, problems such as component loosening and displacement were likely to occur, further affecting the continuity and accuracy of wire laying, resulting in increased construction costs and extended construction periods for power engineering. Given these defects of traditional wire laying devices, it is extremely urgent to develop a new type, efficient, and highly adaptable wire laying device for power engineering lines. Summary of the Invention
[0005] Object of the Invention: The object of the present invention is to provide convenient and stable wire rewinding and paying-out; another object of the present invention is to provide flexible adjustment of the guiding position of the wire.
[0006] Technical Solution: A wire laying device for power engineering lines includes a support plate. A wire storage cavity is fixedly connected to the left side of the upper surface of the support plate. A rotating groove is opened inside the wire storage cavity. A rotating column is rotatably connected to the rear surface inside the rotating groove. A wire reel is fixedly connected to the outer sidewall of the rotating column. An outlet opening is opened on the right side inside the rotating groove. The front end of the rotating column penetrates to the front surface of the wire storage cavity and is fixedly connected with a limiting ring. Locking openings are symmetrically opened on the outer sidewall of the limiting ring. A locking cavity is fixedly connected to the front surface of the wire storage cavity, above the limiting ring.
[0007] Further, a sliding plate is slidably connected inside the locking cavity. A locking head is fixedly connected to the lower surface of the sliding plate. A wedge-shaped block is fixedly connected to the bottom end of the locking head. The wedge-shaped block penetrates below the locking cavity and is snap-connected to the locking port. A toggling block is fixedly connected to the front surface of the sliding plate. A vertical sliding groove is formed in the front surface of the locking cavity. The inner sidewall of the vertical sliding groove is slidably connected to the outer sidewall of the toggling block. Springs are symmetrically and fixedly connected between the lower surface of the sliding plate and the inner lower surface of the locking cavity.
[0008] Further, square cavities are symmetrically and fixedly connected to the upper surface on the right side of the support plate. Circular grooves are respectively formed inside the square cavities. Rotary disks are rotatably connected inside the circular grooves. A cross bar is fixedly connected between the rotary disks. Positioning grooves are symmetrically formed in the outer sidewalls of the rotary disks. A support rod is fixedly connected to the outer sidewall of the cross bar. An adjustment ring is fixedly connected to the top end of the support rod.
[0009] Further, a horizontal groove is formed in the lower surface of the circular groove. A sliding bar is slidably connected inside the horizontal groove. A locking bar is fixedly connected to the upper surface of the sliding bar. The top ends of the locking bars all extend into the circular groove and are snap-connected to the adjacent positioning grooves. The right end of the sliding bar extends to the right side of the horizontal groove and is fixedly connected to a connecting bar. A pedal is fixedly connected to the right side of the connecting bar.
[0010] Further, reset cavities are fixedly connected to the outer sidewalls on the right side of the square cavities. Sliding disks are slidably connected inside the reset cavities. Fixed columns are fixedly connected to the lower surfaces of the sliding disks. The fixed columns are all fixedly connected to the upper surfaces of the adjacent sliding bars. Return springs are wound around the outer sidewalls of the fixed columns. The bottom ends of the return springs are fixedly connected to the inner sidewalls of the reset cavities. The top ends of the return springs are fixedly connected to the outer sidewalls of the fixed columns.
[0011] Further, a limiting groove is formed in the right side of the support plate. A limiting block is slidably connected inside the limiting groove. Grooves are symmetrically formed in the inner sidewall of the limiting groove. Protrusions are symmetrically and fixedly connected to the outer sidewall of the limiting block. The right side of the limiting block is fixedly connected to the outer sidewall of the connecting bar.
[0012] Further, a plurality of self-locking universal wheels are symmetrically and fixedly connected to the lower surface of the support plate.
[0013] Further, a push-pull handle is fixedly connected to the upper surface on the left side of the support plate.
[0014] Beneficial effects: The line pay-out device for electric power engineering projects is very ingenious in the design of pay-out and take-up operation, which brings a convenient and stable working experience. In the preparation stage, the wedge block at the bottom of the locking head is tightly engaged with the locking port on the limit ring, which cleverly limits the winding drum to rotate clockwise, that is, it can only pay out the wire but not take it up. This initial setting provides order guarantee for subsequent work. When it is actually necessary to pay out the wire, the operator only needs to pull up the bend block, which slides smoothly along the vertical slide groove, driving the slide plate to move forward in the locking cavity, and then easily disengage the wedge block from the locking port, instantly releasing the lock on the winding drum, allowing the winding drum to rotate freely around the rotating column in the rotating groove, and the cable can be smoothly released from the outlet. After the pay-out is completed, release the bend block, and the elastic potential energy of the spring immediately takes effect, pushing the slide plate to drive the locking head and the wedge block to move downward quickly, accurately re-engage the locking port, and firmly lock the winding drum to prevent it from rotating at will. The whole process is easy to operate, and the winding drum is stable and reliable in switching between the locked and unlocked states, which greatly improves the efficiency and safety of the wire laying work, effectively avoids problems such as cable entanglement caused by accidental rotation of the winding drum, and ensures the smooth progress of the wire laying work of the power engineering line;
[0015] In terms of meeting the needs of different cable laying scenarios, the device has a very sophisticated design for adjusting the cable guide position. Before preparing to lay the cable, the top of the locking bar is accurately inserted into the positioning groove on the outer wall of the turntable, so that the turntable and the crossbar are firmly fixed. At this time, the adjustment circle is in the initial fixed position, which can provide preliminary guidance for the cable. However, in the face of complex and diverse cable laying scenarios, when the position angle of the cable needs to be adjusted, the operator only needs to step on the pedal, which drives the connecting bar to move downward, and then pulls the slide bar to slide smoothly downward in the cross groove, so that the locking bar quickly disengages from the positioning groove and instantly unlocks the turntable. The operator can easily turn the turntable and the crossbar to drive the adjustment circle to the appropriate angle. After the adjustment is completed, release the pedal, the powerful elastic force of the reset spring takes effect immediately, the slide plate drives the fixed column and the slide bar to quickly reset upward, and the locking bar is accurately inserted into the corresponding positioning groove again, locking the turntable and the adjustment circle firmly in the new position. This flexible adjustment mechanism can accurately meet the diverse requirements of different cable laying scenarios for cable guide positions, significantly improving the applicability of the device and ensuring that power engineering line laying work can be efficiently completed in various complex environments.

[0024] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
[0025] Embodiment
[0026] As Figures 1-7 shown, a wire laying device for a power engineering line is provided, which includes a support plate 1. A wire storage cavity 2 is fixedly connected to the left side of the upper surface of the support plate 1. A rotating groove 3 is opened inside the wire storage cavity 2. A rotating column 4 is rotatably connected to the rear surface of the inside of the rotating groove 3. A winding cylinder 5 is fixedly connected to the outer side wall of the rotating column 4. A wire outlet 6 is opened on the right side of the inside of the rotating groove 3. The front end of the rotating column 4 penetrates to the front surface of the wire storage cavity 2 and is fixedly connected with a limiting ring 7. Locking ports 8 are symmetrically opened on the outer side wall of the limiting ring 7. On the front surface of the wire storage cavity 2, above the limiting ring 7, a locking cavity 9 is fixedly connected. A slide plate 10 is slidably connected to the inside of the locking cavity 9. A locking head 11 is fixedly connected to the lower surface of the slide plate 10. A wedge block 12 is fixedly connected to the bottom end of the locking head 11. The wedge block 12 penetrates below the locking cavity 9 and is engaged with the locking port 8. A lever block 13 is fixedly connected to the front surface of the slide plate 10. A vertical sliding groove 14 is opened on the front surface of the locking cavity 9. The inner side wall of the vertical sliding groove 14 is slidably connected with the outer side wall of the lever block 13. Symmetrically fixed connection springs 37 are arranged between the lower surface of the slide plate 10 and the lower surface of the inside of the locking cavity 9;
[0027] In the preparation stage, the cable is pre-wound around the winding drum 5. The winding drum 5 is installed in the rotating groove 3 in the cable storage cavity 2 through the rotating column 4. At this time, the wedge block 12 at the bottom of the locking head 11 is engaged with the locking port 8 on the limiting ring 7, so that the winding drum 5 can only rotate clockwise, can only pay out the cable, and cannot take in the cable. When the cable needs to be paid out or taken in, the operator opens the cable storage cavity 2 and pulls up the lever block 13. The lever block 13 slides along the vertical sliding groove 14, driving the sliding plate 10 to move forward in the locking cavity 9, and then the wedge block 12 disengages from the locking port 8, releasing the locking of the winding drum 5. At this time, the winding drum 5 can rotate around the rotating column 4 in the rotating groove 3, and the cable is released from the cable outlet 6. As the cable is paid out, the winding drum 5 continues to rotate. When paying out the cable, release the lever block 13. Under the action of the spring 37, the sliding plate 10 drives the locking head 11 and the wedge block 12 to move downward, and re-engages with the locking port 8, locking the winding drum 5 again to prevent it from rotating randomly.
[0028] In this embodiment, square cavities 15 are symmetrically and fixedly connected to the upper surface on the right side of the support plate 1. Circular grooves 16 are respectively formed inside the square cavities 15. Turntables 17 are respectively rotatably connected inside the circular grooves 16. A cross bar 18 is fixedly connected between the turntables 17. Positioning grooves 19 are symmetrically formed on the outer side walls of the turntables 17. A support rod 35 is fixedly connected to the outer side wall of the cross bar 18. An adjustment ring 36 is fixedly connected to the top end of the support rod 35. A horizontal groove 20 is formed on the lower surface of the circular groove 16. A slide bar 22 is slidably connected inside the horizontal groove 20. A locking bar 21 is fixedly connected to the upper surface of the slide bar 22. The top ends of the locking bars 21 all extend into the circular groove 16 and are engaged with the adjacent positioning grooves 19. The right end of the slide bar 22 extends to the right side of the horizontal groove 20 and is fixedly connected to a connecting bar 23. A pedal 24 is fixedly connected to the right side of the connecting bar 23. Reset cavities 25 are fixedly connected to the outer side walls on the right side of the square cavities 15. Slide plates 26 are respectively slidably connected inside the reset cavities 25. Fixed columns 27 are fixedly connected to the lower surfaces of the slide plates 26. The fixed columns 27 are all fixedly connected to the upper surfaces of the adjacent slide bars 22. Return springs 28 are wound around the outer side walls of the fixed columns 27. The bottom ends of the return springs 28 are fixedly connected to the inner side walls of the reset cavities 25. The top ends of the return springs 28 are fixedly connected to the outer side walls of the fixed columns 27;
[0029] Before preparing for wire laying, the top of the locking bar 21 is snapped into the positioning groove 19 on the outer side wall of the turntable 17, so that the turntable 17 and the cross bar 18 are fixed. At this time, the adjustment ring 36 is in an initial fixed position for initially guiding the cable. When it is necessary to adjust the position and angle of the cable, the operator steps on the pedal 24, and the pedal 24 drives the connecting bar 23 to move downward, thereby pulling the sliding bar 22 to slide downward in the horizontal groove 20. When the sliding bar 22 moves, it drives the locking bar 21 to disengage from the positioning groove 19, releasing the lock on the turntable 17. After adjusting to the appropriate angle, the pedal 24 is released. Under the elastic force of the return spring 28, the sliding disk 26 drives the fixed column 27 and the sliding bar 22 to reset upward, and the locking bar 21 snaps into the corresponding positioning groove 19 again, locking the turntable 17 and the adjustment ring 36 at a new position again, so as to realize the adjustment of the cable guiding position to meet the requirements of different wire laying scenarios.
[0030] In this embodiment, a limiting groove 29 is opened on the right side of the support plate 1, a limiting block 30 is slidably connected inside the limiting groove 29, grooves 31 are symmetrically opened on the inner side wall of the limiting groove 29, and bumps 32 are symmetrically and fixedly connected to the outer side wall of the limiting block 30;
[0031] When the operator steps on the pedal 24 for adjustment operation, the connecting bar 23 moves downward, driving the connected limiting block 30 to slide downward synchronously in the limiting groove 29. During this process, the bump 32 slides in the limiting groove 29, and the limiting groove 29 plays a guiding role for the limiting block 30 to ensure the smooth movement of the connecting bar 23, accurately drive the sliding bar 22 to act, and assist in realizing the locking and unlocking operations of the turntable 17. After the operation is completed, the return spring 28 drives the connecting bar 23 to reset upward, and the limiting block 30 also slides upward synchronously in the limiting groove 29 to return to the initial position, completing an operation cycle.
[0032] In this embodiment, a plurality of self-locking universal wheels 33 are symmetrically and fixedly connected to the lower surface of the support plate 1;
[0033] When the device needs to be transferred to a working location, unlock the self-locking universal wheels 33. The operator pushes the device, and the plurality of self-locking universal wheels rotate flexibly, so that the support plate 1 and the entire device can be conveniently moved to the designated position. After reaching the working position to meet the site requirements of different wire laying scenarios, start the locking function of the self-locking universal wheels 33 to make them fixed, provide stable support for the wire laying operation, prevent the device from randomly displacing during the wire laying process, and ensure the safety and stability of the operation.
[0034] In this embodiment, a push-pull handle 34 is fixedly connected to the left side of the upper surface of the support plate 1;
[0035] Before preparing the transfer device, the operator first comes to the device and holds the push-pull handle 34 located on the left side of the upper surface of the support plate 1. At this time, it is necessary to ensure that the self-locking universal wheels 33 are in the unlocked state. The operator exerts force to push or pull the push-pull handle 34, and with the lever action of the handle, it is easier to drive the device to move. With the cooperation of multiple self-locking universal wheels 33, the device can be conveniently moved to the designated wire laying position in the expected direction of the operator. When reaching the destination, put down the push-pull handle and immediately lock the self-locking universal wheels to make the device firmly in place and prepare to carry out the wire laying operation.
