Elastic pay-off trolley with adjustable function

Abstract

This utility model discloses an adjustable elastic wire-laying trolley, including a mounting frame. A rotating shaft is rotatably mounted inside the mounting frame, and a guide wheel is fixedly mounted on the surface of the rotating shaft. A connecting plate is bolted to the inside of the mounting frame, and a mounting plate is fixedly mounted inside the mounting frame. An elastic telescopic component is installed inside the mounting plate. The wire pushes the component, causing the mounting frame to move upwards, compressing the elastic telescopic component. This causes the mounting frame to move the conductive sheet upwards, maintaining a fixed distance between the conductive sheet and the wire. This ensures that the conductive sheet applies the same pressure to wires of different diameters, allowing for stable operation whether laying large or small cross-section wires. This improves the versatility and applicability of the elastic wire-laying trolley and prevents excessive pressure from the conductive sheet on the wire, which could damage the guide surface.

Description

Technical Field

[0001] This utility model relates to the field of flexible wire feeding pulley technology, and in particular to an adjustable flexible wire feeding pulley. Background Technology

[0002] When laying power cables, cable laying pulleys are often used to prevent the cable surface from being worn down, such as friction between the cable and the ground, friction between the cable and building corners (such as well openings, cable trench corners, etc.) when the cable changes direction, friction between the cable and the pipe openings when the cable passes through multiple parallel cable pipes in sequence, and friction between the cable and the pipe openings when the cable passes through two cable pipes at an angle to each other.

[0003] During the construction of power lines, when the conductors are laid parallel to or across other transmission lines, or when one circuit of a double-circuit power line is energized while the other circuit is de-energized, electromagnetic induced currents are easily generated on the construction conductors. Generally, conductive devices are used to conduct the induced currents on the conductors to the ground, thereby eliminating the induced currents on the conductors.

[0004] However, when laying power cables, the specifications of the conductors vary depending on the usage requirements. However, the conductive device on the existing flexible cable laying trolley is installed in a fixed position, which causes the pressure of the conductive device contacting conductors of different specifications to be different. When the conductor diameter is too large, the conductive device will apply too much pressure to the conductor, which will cause the conductor to be damaged due to excessive pressure. Based on the above problems, this application proposes a flexible cable laying trolley with adjustable function. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable elastic wire feeding trolley to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable elastic wire feeding trolley includes a mounting frame, a rotating shaft rotatably mounted inside the mounting frame, a guide wheel fixedly mounted on the surface of the rotating shaft, a connecting plate bolted inside the mounting frame, a mounting plate fixedly mounted inside the mounting frame, an elastic telescopic component inside the mounting plate, a mounting bracket mounted at the bottom of the mounting plate via the elastic telescopic component, a pushing component on the left side of the mounting bracket, and a conductive sheet bolted to the right side of the mounting bracket.

[0008] Preferably, the elastic telescopic component includes a mounting groove formed at the bottom of the mounting plate, a sliding plate slidably disposed inside the mounting groove, a spring connecting the top of the sliding plate and the upper sidewall of the mounting groove, an external threaded sleeve overlapping the bottom of the sliding plate and threadedly connected to the mounting groove, a rotating plate fixedly disposed at the bottom of the mounting groove, a moving rod overlapping the inside of the rotating plate, the moving rod being fixedly installed at the bottom of the sliding plate, and a mounting bracket being fixedly installed at the bottom end of the moving rod.

[0009] Preferably, there are several movable rods, and the several mounting brackets are arranged in a linear array, and the mounting brackets are made of metal.

[0010] Preferably, the pushing component includes an L-shaped plate fixedly installed on the left side of the mounting frame, a rectangular block overlapping inside the L-shaped plate, a fixing stud fixedly installed on the top of the rectangular block, a washer nut with counterclockwise threads on the surface of the fixing stud, a mounting base fixedly installed at the bottom of the rectangular block, and a connecting roller fixedly installed at the bottom of the mounting base.

[0011] Preferably, a rectangular through groove is provided through the lower side wall of the L-shaped plate, the rectangular block is located inside the rectangular through groove, and the transverse cross-sectional area of ​​the rectangular block is the same as the transverse cross-sectional area of ​​the rectangular through groove.

[0012] Preferably, the conductive sheet includes a rubber plate, which is connected to the mounting bracket by bolts. A fixing rivet is installed inside the rubber plate, and a conductive strip is installed inside the rubber plate. A high-elastic steel sheet is fixedly disposed inside the conductive strip.

[0013] Preferably, the number of conductive sheets is several, and the several conductive sheets are distributed in a linear array.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the wire enters the guide wheel and passes through, the wire will push the mounting frame upward through the pushing component, causing the mounting frame to compress the elastic telescopic component, which in turn causes the mounting frame to move the conductive sheet upward, maintaining a fixed distance between the conductive sheet and the wire. This ensures that the conductive sheet applies the same pressure to wires of different diameters, allowing for stable operation whether laying large or small cross-section wires. This improves the versatility and applicability of the elastic wire laying trolley and avoids excessive pressure on the wire by the conductive sheet, which could damage the guide surface.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Refer to Figure 1-5An adjustable elastic wire-feeding trolley includes a mounting frame 1, a rotating shaft 2 rotatably mounted inside the mounting frame 1, a guide wheel 3 fixedly mounted on the surface of the rotating shaft 2, a connecting plate 4 bolted inside the mounting frame 1, a mounting plate 5 fixedly mounted inside the mounting frame 1, an elastic telescopic component inside the mounting plate 5, a mounting bracket 12 mounted at the bottom of the mounting plate 5 via the elastic telescopic component, a pushing component on the left side of the mounting bracket 12, and conductive sheets 13 bolted to the right side of the mounting bracket 12. The number of conductive sheets 13 is several, and the several conductive sheets 13 are arranged in a linear array. The elastic telescopic component includes a mounting groove 6 formed at the bottom of the mounting plate 5, a sliding plate 7 slidably mounted inside the mounting groove 6, a spring 8 connecting the top of the sliding plate 7 and the upper sidewall of the mounting groove 6, an external threaded sleeve 9 overlapping the bottom of the sliding plate 7 and threadedly connected to the mounting groove 6, a rotating plate 10 fixedly mounted at the bottom of the mounting groove 6, and several moving rods 11 overlapping the rotating plate 10. The mounting brackets 12 are arranged in a linear array and are made of metal. The moving rod 11 is fixedly mounted on the bottom of the sliding plate 7, and the mounting brackets 12 are fixedly mounted on the bottom end of the moving rod 11. The wires drive the mounting brackets 12 to move via a pushing assembly, causing the mounting brackets 12 to compress the spring 8 via the moving rod 11 and the sliding plate 7. This causes the mounting brackets 12 to move the conductive sheet 13, maintaining a fixed distance between the conductive sheet 13 and wires of different radii, thus allowing the conductive sheet 13 to apply pressure to wires of different radii. Similarly, when spring 8 is damaged, the rotating plate 10 drives the external threaded sleeve 9 to rotate, causing the external threaded sleeve 9 to move out of the mounting groove 6. The mounting bracket 12 drives the sliding plate 7 to move out of the mounting groove 6 via the moving rod 11, removes the spring 8 that was in contact with the mounting groove 6, and inserts a new spring 8. The mounting bracket 12 then inserts the sliding plate 7 into the mounting groove 6 via the moving rod 11, and the rotating plate 10 drives the external threaded sleeve 9 to tighten inside the mounting groove 6, thus limiting the sliding plate 7.

[0023] Specifically, the pushing component includes an L-shaped plate 14 fixedly mounted on the left side of the mounting bracket 12. A rectangular block 15 is overlapped inside the L-shaped plate 14. A fixing stud 16 is fixedly mounted on the top of the rectangular block 15. A washer nut 17 is counterclockwise threaded on the surface of the fixing stud 16. A mounting base 18 is fixedly mounted on the bottom of the rectangular block 15. A connecting roller 19 is fixedly mounted on the bottom of the mounting base 18. A rectangular through groove is provided through the lower side wall of the L-shaped plate 14. The rectangular block 15 is located inside the rectangular through groove, and the transverse cross-sectional area of ​​the rectangular block 15 is equal to the rectangular cross-sectional area of ​​the rectangular block 15. The transverse cross-sectional area of ​​the through groove is the same. When the connecting roller 19 is worn and needs to be replaced, the washer nut 17 is removed from the fixing stud 16. The connecting roller 19 drives the mounting base 18 to move, so that the mounting base 18 drives the rectangular block 15 out of the L-shaped plate 14. The replacement connecting roller 19 drives the mounting base 18, so that the mounting base 18 drives the rectangular block 15 to insert into the interior of the L-shaped plate 14. The washer nut 17 is tightened on the surface of the fixing stud 16, and the worn connecting roller 19 can be replaced.

[0024] Specifically, the conductive sheet 13 includes a rubber plate 131, which is connected to the mounting bracket 12 by bolts. A fixing rivet 132 is installed inside the rubber plate 131, and a conductive strip 133 is installed inside the rubber plate 131. A high-elastic steel sheet 134 is fixedly installed inside the conductive strip 133. When the wire passes under the conductive sheet 13, the wire will push the conductive strip 133 to drive the high-elastic steel sheet 134 to fully rotate. The high-elastic steel sheet 134 and the conductive strip 133 will cause the rubber plate 131 to rotate. After rotating, the high-elastic steel sheet 134 has a rebound force, which makes the high-elastic steel sheet 134 completely fit the conductive strip 133 and the wire, thereby facilitating the discharge of the induced current on the wire.

[0025] In use: When the wire passes through the inside of the wire wheel 3, the wire pushes the connecting roller 19 to move upward, causing the connecting roller 19 to move the mounting base 18 upward. The mounting base 18 then pushes the L-shaped plate 14 to move the mounting frame 12 upward, causing the mounting frame 12 to move the conductive sheet 13 upward. The mounting frame 12 then moves the moving rod 11 upward, causing the moving rod 11 to move the sliding plate 7 to compress the spring 8. The conductive sheet 13 contacts the wire during the wire laying process, automatically drawing the induced current from the wire and introducing it to the ground through the grounding wire. After the wire laying is completed, the spring 8 pushes the sliding plate 7 to reset the moving rod 11, causing the moving rod 11 to reset the mounting frame 12, which in turn resets the conductive sheet 13. The L-shaped plate 14 moves the rectangular block 15 through the fixing stud 16 and washer nut 17, causing the rectangular block 15 to move the mounting base 18, which in turn resets the connecting roller 19. This allows the conductive sheet 13 to adaptively adjust according to the specifications of the wire.
