Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and more specifically, to a low-voltage cable laying meter and cable laying frame. Background Technology

[0002] A cable length counter is a device specifically designed to measure the length of cables. It achieves accurate measurement of cable length through built-in sensors or by measuring the circumference and number of rotations of a roller. The basic principle of a cable length counter is to measure its length by detecting the linear movement of the cable. Specifically, the sensor or roller inside the counter rotates as the cable moves, recording the distance the cable travels. This distance is then calculated to obtain the accurate length of the cable.

[0003] During cable laying, multiple cables are sometimes laid. However, existing technology uses multiple meter counters to calculate the length of multiple cables, resulting in serious waste. Summary of the Invention

[0004] This invention provides a low-voltage cable laying and metering device and a cable laying frame, which can overcome some or all the defects of the prior art.

[0005] According to the present invention, a low-voltage cable laying and metering device and a cable laying frame are provided, which include a device body, the device body including a mounting frame, a laying area is formed at the mounting frame, a rotating shaft is rotatably provided at the laying area, and a meter counter connected to the rotating shaft is provided at the mounting frame, the meter counter being used to measure the rotation stroke of the rotating shaft.

[0006] The rotating shaft is detachably provided with multiple mounting parts, including a connector that mates with the outer wall of the rotating shaft. Both ends of the connector are provided with limit components corresponding to the rotating shaft. Both ends of the connector are detachably provided with drive rings, which are used to drive the limit components to achieve locking or unlocking between the connector and the rotating shaft.

[0007] The low-voltage cable laying and metering device disclosed herein involves installing a number of mounting pieces corresponding to the required number of cables to be laid onto a rotating shaft during use. The mounting pieces are then locked to the rotating shaft via a drive mechanism. The cable to be calculated is then placed on the corresponding mounting piece. As the cable moves, it causes the corresponding mounting piece to rotate. Since the mounting piece is locked to the rotating shaft, the mounting piece drives the rotating shaft to rotate together, thereby causing the meter counter to calculate the travel distance of the rotating shaft, which in turn calculates the length of the laid cable.

[0008] Once any cable is laid, the limit switch between the frame and the rotating shaft corresponding to the laid cable is released via the drive ring, allowing the mounting piece on the corresponding cable to rotate and connect with the rotating shaft. The counting data is then recorded. The remaining cables continue to be laid. Because the mounting piece corresponding to the laid cable is rotatably connected to the rotating shaft, the rotation of the shaft will not cause the mounting piece corresponding to the laid cable to rotate, thus not affecting the counting of other cable lengths. This allows for the counting of multiple cables using a single meter counter. Compared to existing technologies, by setting multiple mounting pieces at the rotating shaft, the length of multiple cables can be counted simultaneously and continuously, saving costs. Furthermore, this invention has a simple structure, strong practicality, and is convenient for production and transportation.

[0009] Preferably, the connector includes an upper fixed shell and a lower fixed shell that are detachably fitted to the outer wall of the shaft. Both ends of the upper and lower fixed shells have extensions, and a first threaded end for threaded installation of a drive ring is formed between the extensions at the same end. Each extension has a through groove for installation of a limiting component.

[0010] With the upper and lower fixed shells detachably engaging with the outer wall of the shaft, the connecting parts can be quickly disassembled and installed without disassembling the shaft.

[0011] It is understandable that by setting the rotating drive ring, the limiting component can be driven to move within the through slot, thereby locking or unlocking the connector and the rotating shaft, and a limit can also be formed between the upper and lower fixed shells.

[0012] Preferably, the limiting component includes a locking block slidably disposed in the through groove, a sliding groove is formed on the side wall of the through groove, an extension portion extending into the sliding groove is formed at the corresponding position of the locking block and the sliding groove, and a spring is provided between the bottom wall of the extension portion and the bottom wall of the sliding groove, the spring being used to provide elastic force to keep the extension portion pressed upward.

[0013] The above structure ensures that when the block is not squeezed by the drive ring, the spring force keeps the block separated from the shaft.

[0014] Preferably, a plurality of positioning grooves corresponding to the locking block are formed on the outer wall of the rotating shaft, and the plurality of positioning grooves are equally spaced on the outer wall of the rotating shaft.

[0015] With the above structure, when the locking block is squeezed by the drive ring, it can be tightly locked in the positioning groove, thus achieving stable locking between the mounting part and the rotating shaft.

[0016] Understandably, by using the spring mechanism, when the drive ring releases its pressure on the locking block, the locking block can quickly disengage from the positioning groove, thereby releasing the lock between the mounting component and the rotating shaft.

[0017] Preferably, multiple annular grooves are formed on the outer wall of the rotating shaft, and positioning protrusions that cooperate with the corresponding annular grooves are formed on the inner walls of the upper and lower fixed shells. The multiple annular grooves are provided at equal intervals on the outer wall of the rotating shaft.

[0018] By inserting the positioning protrusions of the upper and lower fixed shells into the annular groove of the rotating shaft, a stable connection between the connector and the rotating shaft can be achieved, and the connector can be limited in the axial direction of the rotating shaft to prevent the connector from shifting or misaligning during rotation.

[0019] Preferably, an alignment portion extending downward is formed at the bottom wall of the upper fixed shell, and an alignment groove for the alignment portion to be inserted is formed at the top wall of the lower fixed shell.

[0020] By inserting the alignment part of the upper fixed shell into the alignment groove of the lower fixed shell, it can be ensured that the upper and lower fixed shells can be accurately aligned and installed during the installation process, avoiding deviation or misalignment of the connecting parts during installation, thereby improving the installation stability between the upper and lower fixed shells.

[0021] Preferably, threaded portions are formed at the top walls of both ends of the upper and lower fixed shells, and the threaded portions at the same end together form a second threaded end, and an adjusting ring is threaded at the second threaded end.

[0022] Preferably, baffles are formed on opposite sides of adjacent adjusting rings, and a laying gap is formed between adjacent baffles to cooperate with the cable.

[0023] By adjusting the second threaded end of the ring and the baffle, the ring can limit the movement between the upper and lower fixed shells, and the width of the laying gap can be adjusted by rotating the ring. This allows the laying gap to be limited for cables of different diameters, which improves the stability of the cable during installation and enhances the transmission effect between the cable and the installation components.

[0024] Preferably, grooves are formed on the outer walls of both the upper and lower fixing shells, and rubber pads are formed in the grooves. Adjacent grooves together form a guide groove that mates with the bottom wall of the cable.

[0025] The guide groove ensures that the cable moves along a predetermined path during the laying process. Combined with the rubber pad, it increases the friction between the upper and lower fixing shells and the cable, ensuring the stability and continuity of the cable during the laying process.

[0026] A cable laying frame includes a horizontally arranged fixing part formed on the side wall of the frame, and a low-voltage cable laying metering device as described above is provided on the top wall of the frame.

[0027] The above structure allows the device to be installed in any location, improving its practicality. Attached Figure Description

[0035] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0036] Example 1

[0037] Please see Figure 1-7 This embodiment provides a low-voltage cable laying and measuring device, which includes a device body 100, a mounting frame 110, a pulling area formed at the mounting frame 110, a rotating shaft 120 rotatably provided at the pulling area, and a measuring device 130 connected to the rotating shaft 120 at the mounting frame 110. The measuring device 130 is used to measure the rotation stroke of the rotating shaft 120.

[0038] Multiple mounting parts 140 are detachably provided at the rotating shaft 120. Each mounting part 140 includes a connector that mates with the outer wall of the rotating shaft 120. Limiting components are formed at both ends of the connector corresponding to the rotating shaft 120. A drive ring 350 is detachably provided at both ends of the connector. The drive ring 350 is used to drive the limiting components to achieve locking or unlocking between the connector and the rotating shaft 120.

[0039] The low-voltage cable laying and metering device disclosed herein involves installing a number of mounting pieces 140 corresponding to the number of cables to be laid onto a rotating shaft 120 during use. The mounting pieces 140 are locked to the rotating shaft 120 by a driving component. Then, the cable to be calculated is placed on the corresponding mounting piece 140. When the cable moves, it will drive the corresponding mounting piece 140 to rotate. Since the mounting piece 140 is locked to the rotating shaft 120, the mounting piece 140 will drive the rotating shaft 120 to rotate together, thereby driving the meter counter 130 to calculate the travel of the rotating shaft 120, that is, to calculate the length of the laid cable.

[0040] Once any cable is laid, the limit switch between the frame 150 and the rotating shaft 120 corresponding to the laid cable is released via the drive ring 350, allowing the mounting piece 140 on the corresponding cable to rotate and connect with the rotating shaft 120. The counting data is then recorded. The remaining cables continue to be laid. Because the mounting piece 140 corresponding to the laid cable is rotatably connected to the rotating shaft 120, the rotation of the rotating shaft 120 will not cause the mounting piece 140 corresponding to the laid cable to rotate, thus not affecting the counting of other cable lengths. This allows for the counting of multiple cables using a single meter counter 130. Compared to existing technologies, by setting multiple mounting pieces 140 at the rotating shaft 120, the length of multiple cables can be counted simultaneously and continuously, saving costs. Furthermore, this invention has a simple structure, strong practicality, and is convenient for production and transportation.

[0041] In this embodiment, the connector includes an upper fixed shell 310 and a lower fixed shell 320 that are detachably fitted to the outer wall of the rotating shaft 120. Both ends of the upper fixed shell 310 and the lower fixed shell 320 have extensions 330. A first threaded end 331 for threaded installation of the drive ring 350 is formed between the extensions 330 at the same end. Each extension 330 has a through groove 710 for installation of the limiting component.

[0042] With the upper fixed shell 310 and the lower fixed shell 320 detachably engaged with the outer wall of the rotating shaft 120, the connecting parts can be quickly disassembled and installed without disassembling the rotating shaft 120.

[0043] It is understandable that by setting the rotating drive ring 350, the limiting component can be driven to move within the through groove 710 to lock or unlock the connector and the rotating shaft 120, and a limit can also be formed between the upper fixed shell 310 and the lower fixed shell 320.

[0044] In this embodiment, the limiting component includes a locking block 720 slidably disposed in the through groove 710. A sliding groove 730 is formed on the side wall of the through groove 710. An extension portion 740 extending into the sliding groove 730 is formed at the corresponding position of the locking block 720 and the sliding groove 730. A spring 750 is provided between the bottom wall of the extension portion 740 and the bottom wall of the sliding groove 730. The spring 750 is used to provide elastic force to keep the extension portion 740 pressed upward.

[0045] With the above structure, when the locking block 720 is not squeezed by the drive ring 350, the elastic force of the spring 750 keeps the locking block 720 in a state of separation from the rotating shaft 120.

[0046] In this embodiment, a plurality of positioning grooves 210 corresponding to the locking block 720 are formed on the outer wall of the rotating shaft 120, and the plurality of positioning grooves 210 are equally spaced on the outer wall of the rotating shaft 120.

[0047] With the above structure, when the locking block 720 is squeezed by the drive ring 350, the locking block 720 can be tightly locked in the positioning groove 210, thus achieving a stable lock between the mounting part 140 and the rotating shaft 120.

[0048] Understandably, with the cooperation of the spring 750, when the drive ring 350 releases its pressure on the locking block 720, the locking block 720 can quickly disengage from the positioning groove 210, thereby releasing the lock between the mounting part 140 and the rotating shaft 120.

[0049] In this embodiment, a plurality of annular grooves 220 are formed on the outer wall of the rotating shaft 120, and positioning protrusions 410 that cooperate with the corresponding annular grooves 220 are formed on the inner walls of the upper fixed shell 310 and the lower fixed shell 320. The plurality of annular grooves 220 are provided at equal intervals on the outer wall of the rotating shaft 120.

[0050] By inserting the positioning protrusions 410 of the upper fixed shell 310 and the lower fixed shell 320 into the annular groove 220 of the rotating shaft 120, a stable connection between the connector and the rotating shaft 120 can be achieved, and the connector can be limited in the axial direction of the rotating shaft 120 to prevent the connector from shifting or misaligning during rotation.

[0051] In this embodiment, an alignment portion 520 extending downward is formed at the bottom wall of the upper fixing shell 310, and an alignment groove 510 for the alignment portion 520 to be inserted is formed at the top wall of the lower fixing shell 320.

[0052] By inserting the alignment portion 520 of the upper fixing shell 310 into the alignment groove 510 of the lower fixing shell 320, it can be ensured that the upper fixing shell 310 and the lower fixing shell 320 can be accurately aligned and installed during the installation process, avoiding deviation or misalignment of the connectors during the installation process, thereby improving the installation stability between the upper fixing shell 310 and the lower fixing shell 320.

[0053] Example 2

[0054] Seen in Figure 2-7 This embodiment also provides a low-voltage cable laying and metering device, which differs from Embodiment 1 in that: threaded portions 340 are formed at the top walls of both ends of the upper fixed shell 310 and the lower fixed shell 320, and the threaded portions 340 at the same end together form a second threaded end, and an adjusting ring 360 is threaded at the second threaded end.

[0055] Each adjacent adjusting ring 360 has a baffle 370 on its opposite side, and a laying gap 420 is formed between adjacent baffles 370 to cooperate with the cable.

[0056] By adjusting the second threaded end of the adjusting ring 360 and the retaining plate 370, the adjusting ring 360 can limit the movement between the upper fixed shell 310 and the lower fixed shell 320, and the width of the laying gap 420 can be adjusted by rotating the adjusting ring 360. This allows the laying gap 420 to limit the movement of cables of different diameters, which improves the stability of the cable during installation and enhances the transmission effect between the cable and the mounting component 140.

[0057] In this embodiment, grooves 530 are formed on the outer walls of both the upper fixing shell 310 and the lower fixing shell 320, and rubber pads are formed in each groove 530. Adjacent grooves 530 together form a guide groove that cooperates with the bottom wall of the cable.

[0058] By setting the guide groove, it can be ensured that the cable moves along the predetermined path during the laying process. In conjunction with the setting of the rubber pad, the friction between the upper fixed shell 310 and the lower fixed shell 320 and the cable is increased, ensuring the stability and continuity of the cable during the laying process.

[0059] Example 3

[0060] Seen in Figure 1 This embodiment provides a cable laying frame, which includes a horizontally arranged fixing part 160 formed on the side wall of the frame body 150, and a low-voltage cable laying meter measuring device as described in either embodiment 1 or embodiment 2 is provided on the top wall of the frame body 150.

[0061] The above structure allows the device to be installed in any location, improving its practicality.

[0062] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0063] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, they should all fall within the protection scope of the present invention.
