Description

Technical Field

[0001] The invention relates to the technical field of cable pay-off, in particular to a low-voltage cable pay-off metering device and a cable pay-off rack. Background Art

[0002] A cable meter is a device specifically used to measure the length of a cable. It can accurately measure the length of a cable through a built-in sensor or based on the circumference of a roller and the number of turns it makes. The basic principle of a cable meter is to measure the length of the cable by detecting its linear movement. Specifically, the sensor or roller inside the meter will rotate as the cable moves, thereby recording the distance the cable moves. After calculating this distance, the exact length of the cable can be obtained.

[0003] During the cable laying process, multiple cables will be laid in some scenarios. However, when calculating the lengths of multiple cables, the existing technology uses multiple meter counters to calculate the lengths of multiple cables, resulting in serious waste. Summary of the invention

[0004] The invention provides a low-voltage cable pay-off meter device and a cable pay-off rack, which can overcome certain or some defects of the prior art.

[0005] According to the present invention, a low-voltage cable pay-off metering device and a cable pay-off stand include a device body, the device body includes a mounting frame, a pulling area is formed at the mounting frame, a rotating shaft is rotatably provided at the pulling area, a meter connected to the rotating shaft is provided at the mounting frame, and the meter is used to measure the rotation stroke of the rotating shaft; A plurality of mounting parts are detachably provided at the rotating shaft, and the mounting parts include a connecting part that cooperates with the outer wall of the rotating shaft. Limiting assemblies are formed at both ends of the connecting part corresponding to the rotating shaft. Driving rings are detachably provided at both ends of the connecting part, and the driving rings are used to drive the limiting assemblies to achieve locking or unlocking between the connecting part and the rotating shaft.

[0006] The present invention discloses a low-voltage cable laying and metering device. When in use, the mounting parts corresponding to the number of cables to be laid are mounted on the rotating shaft, and the mounting parts and the rotating shaft are locked by a driving part. Then, the cables to be calculated are placed on the corresponding mounting parts. When the cables move, the corresponding mounting parts are driven to rotate. Since the mounting parts and the rotating shaft are locked, the mounting parts drive the rotating shaft to rotate together, thereby driving the meter meter to calculate the stroke of the rotating shaft, that is, to calculate the length of the laid cables. When any cable is laid, the limit of the frame and the rotating shaft corresponding to the laid cable is cancelled through the driving ring, so that the mounting piece on the corresponding cable is rotatably connected to the rotating shaft, and then the counting data is recorded, and the remaining cables continue to be pulled and laid. Since the mounting piece corresponding to the laid cable is rotatably connected to the rotating shaft, the rotation of the rotating shaft will not drive the mounting piece corresponding to the laid cable to rotate, and thus will not affect the counting of the lengths of other cables, thereby realizing the counting of multiple cables by one meter. Compared with the prior art, by arranging multiple mounting pieces on the rotating shaft, the lengths of multiple cables can be counted uninterruptedly at the same time, saving costs. In addition, the present invention has a simple structure, strong practicality, and is convenient for production and transportation.

[0007] Preferably, the connecting member includes an upper fixed shell and a lower fixed shell which are detachably matched with the outer wall of the rotating shaft, and extension parts are formed at both ends of the upper fixed shell and the lower fixed shell, and a first threaded end for threaded installation of a drive ring is formed between the extension parts at the same end, and a through groove for installation of a limit assembly is formed at the extension parts.

[0008] By arranging the detachable cooperation between the upper fixed shell and the lower fixed shell and the outer wall of the rotating shaft, the connecting piece can be quickly disassembled and installed without disassembling the rotating shaft.

[0009] It is understandable that, by setting the rotating drive ring, the limiting assembly can be driven to move in the through slot to achieve locking or unlocking between the connecting member and the rotating shaft, and the upper fixed shell and the lower fixed shell can be limited.

[0010] Preferably, the limiting assembly includes a card block slidably arranged in the through slot, a sliding slot is formed at the side wall of the through slot, an extension part extending into the sliding slot is formed at the corresponding position of the card block and the sliding slot, and a spring is arranged between the bottom wall of the extension part and the bottom wall of the sliding slot, and the spring is used to provide an elastic force to keep the extension part pressed upward.

[0011] Through the above structure, when the clamping block is not squeezed by the driving ring, the elastic force of the spring keeps the clamping block always in a state of being separated from the rotating shaft.

[0012] Preferably, a plurality of positioning grooves corresponding to the clamping blocks are formed on the outer wall of the rotating shaft, and the plurality of positioning grooves are arranged at equal intervals on the outer wall of the rotating shaft.

[0013] Through the above structure, when the clamping block is squeezed by the driving ring, the clamping block can be tightly clamped in the positioning groove, thereby achieving stable locking between the mounting member and the rotating shaft.

[0014] It is understandable that, through the coordination of the spring, when the drive ring releases the squeezing of the clamping block, the clamping block can quickly escape from the positioning groove, thereby releasing the lock between the mounting member and the rotating shaft.

[0015] Preferably, a plurality of annular grooves are formed on the outer wall of the rotating shaft, and positioning protrusions cooperating with the corresponding annular grooves are formed on the inner walls of the upper fixed shell and the lower fixed shell, and the plurality of annular grooves are arranged at equal intervals on the outer wall of the rotating shaft.

[0016] By inserting the positioning protrusions of the upper fixed shell and the lower fixed shell into the annular groove of the rotating shaft, a stable connection between the connecting member and the rotating shaft can be achieved, and the connecting member can be limited in the axial direction of the rotating shaft to prevent the connecting member from being offset or misaligned during rotation.

[0017] 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.

[0018] By inserting the alignment portion of the upper fixing shell into the alignment groove of the lower fixing shell, it can be ensured that the upper fixing shell and the lower fixing shell can be accurately aligned and installed during the installation process, avoiding deviation or misalignment of the connecting parts during the installation process, thereby improving the installation stability between the upper fixing shell and the lower fixing shell.

[0019] Preferably, threaded portions are formed at the top walls at both ends of the upper fixed shell and the lower fixed shell, the threaded portions at the same end jointly form a second threaded end, and an adjustment ring is threadedly provided at the second threaded end.

[0020] Preferably, baffles are formed on opposite sides of adjacent adjustment rings, and a laying gap that matches the cable is formed between adjacent baffles.

[0021] Through the coordinated arrangement of the second threaded end of the adjusting ring and the baffle, the adjusting ring can not only limit the position between the upper fixed shell and the lower fixed shell, but also adjust the width of the laying gap by rotating the adjusting ring, so that the laying gap can limit the position of cables of different diameters, which not only improves the stability of the cable during laying, but also improves the transmission effect between the cable and the mounting part.

[0022] Preferably, grooves are formed at the outer walls of the upper fixing shell and the lower fixing shell, rubber pads are formed in the grooves, and adjacent grooves jointly form a guide groove that cooperates with the bottom wall of the cable.

[0023] The setting of the guide groove can ensure that the cable moves along a predetermined path during the pay-out process. The setting of the rubber pad increases the friction between the upper and lower fixed shells and the cable, ensuring the stability and continuity of the cable during the pay-out process.

[0024] A cable pay-off rack comprises a horizontally arranged fixing portion formed on the side wall of the rack body, and any one of the above-mentioned low-voltage cable pay-off metering devices is arranged on the top wall of the rack body.

[0025] Through the above structure, the device can be installed at any position, thereby improving the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0034] Example 1 See also Figure 1-7 The present embodiment provides a low-voltage cable pay-off metering device, which includes a device body 100, the device body 100 includes a mounting frame 110, a pulling area is formed at the mounting frame 110, a rotating shaft 120 is rotatably provided at the pulling area, a meter 130 connected to the rotating shaft 120 is provided at the mounting frame 110, and the meter 130 is used to measure the rotation stroke of the rotating shaft 120; A plurality of mounting members 140 are detachably provided at the rotating shaft 120. The mounting members 140 include connecting members that cooperate with the outer wall of the rotating shaft 120. Limiting assemblies are formed at both ends of the connecting members corresponding to the rotating shaft 120. Driving rings 350 are detachably provided at both ends of the connecting members. The driving rings 350 are used to drive the limiting assemblies to achieve locking or unlocking between the connecting members and the rotating shaft 120.

[0035] The present invention discloses a low-voltage cable laying metering device. When in use, the mounting pieces 140 corresponding to the number of cables to be laid are mounted on the rotating shaft 120, and the mounting pieces 140 and the rotating shaft 120 are locked by a driving piece. Then, the cables to be calculated are placed on the corresponding mounting pieces 140. When the cables move, the corresponding mounting pieces 140 are driven to rotate. Since the mounting pieces 140 and the rotating shaft 120 are locked, the mounting pieces 140 drive the rotating shaft 120 to rotate together, thereby driving the meter 130 to calculate the travel of the rotating shaft 120, that is, the length of the laid cables is calculated. When any cable is laid, the limit of the frame 150 and the rotating shaft 120 corresponding to the laid cable is cancelled through the driving ring 350, so that the mounting piece 140 on the corresponding cable is rotatably connected to the rotating shaft 120, and then the counting data is recorded, and the remaining cables continue to be pulled and laid. Since 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 drive the mounting piece 140 corresponding to the laid cable to rotate, and will not affect the counting of the lengths of other cables, thereby realizing the counting of multiple cables by one meter meter 130. Compared with the prior art, by arranging multiple mounting pieces 140 on the rotating shaft 120, the lengths of multiple cables can be counted uninterruptedly at the same time, saving costs. In addition, the present invention has a simple structure, strong practicality, and is convenient for production and transportation.

[0036] In this embodiment, the connecting member includes an upper fixed shell 310 and a lower fixed shell 320 which are detachably matched with the outer wall of the rotating shaft 120. Extension portions 330 are formed at both ends of the upper fixed shell 310 and the lower fixed shell 320. A first threaded end 331 for threaded installation of the drive ring 350 is formed between the extension portions 330 at the same end, and a through groove 710 for installing a limit assembly is formed at the extension portions 330.

[0037] By detachably cooperating the upper fixing shell 310 and the lower fixing shell 320 with the outer wall of the rotating shaft 120 , the connecting member can be quickly disassembled and installed without disassembling the rotating shaft 120 .

[0038] It is understandable that, by setting the rotating drive ring 350 , the limiting assembly can be driven to move in the through slot 710 to achieve locking or unlocking between the connecting member and the rotating shaft 120 , and the upper fixed shell 310 and the lower fixed shell 320 can be limited.

[0039] In this embodiment, the limiting assembly includes a block 720 slidably disposed in the through groove 710, a sliding groove 730 is formed at the side wall of the through groove 710, an extension portion 740 extending into the sliding groove 730 is formed at the corresponding position between the block 720 and the sliding groove 730, and a spring 750 is provided between the bottom wall of the extension portion 740 and the bottom wall of the sliding groove 730, and the spring 750 is used to provide an elastic force to keep the extension portion 740 pressed upward.

[0040] Through the above structure, when the clamping block 720 is not squeezed by the driving ring 350 , the clamping block 720 is always separated from the rotating shaft 120 due to the elastic force of the spring 750 .

[0041] In this embodiment, a plurality of positioning grooves 210 corresponding to the clamping blocks 720 are formed on the outer wall of the rotating shaft 120 , and the plurality of positioning grooves 210 are arranged at equal intervals on the outer wall of the rotating shaft 120 .

[0042] Through the above structure, when the clamping block 720 is squeezed by the driving ring 350 , the clamping block 720 can be tightly clamped in the positioning groove 210 , thereby achieving stable locking between the mounting member 140 and the rotating shaft 120 .

[0043] It is understandable that, by means of the spring 750 , when the drive ring 350 releases the squeeze on the block 720 , the block 720 can quickly disengage from the positioning groove 210 , thereby releasing the lock between the mounting member 140 and the rotating shaft 120 .

[0044] In this embodiment, a plurality of annular grooves 220 are formed on the outer wall of the rotating shaft 120 , and positioning protrusions 410 cooperating 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 arranged at equal intervals on the outer wall of the rotating shaft 120 .

[0045] 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 connecting member and the rotating shaft 120 can be achieved, and the connecting member can be limited in the axial direction of the rotating shaft 120 to prevent the connecting member from being offset or misaligned during rotation.

[0046] 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 into is formed at the top wall of the lower fixing shell 320 .

[0047] By inserting the alignment portion 520 of the upper fixed shell 310 into the alignment groove 510 of the lower fixed shell 320, it can be ensured that the upper fixed shell 310 and the lower fixed shell 320 can be accurately aligned and installed during the installation process, avoiding deviation or misalignment of the connecting parts during the installation process, thereby improving the installation stability between the upper fixed shell 310 and the lower fixed shell 320.

[0048] Example 2 See Figure 2-7 This embodiment also provides a low-voltage cable pay-out meter device, which differs from Embodiment 1 in that a threaded portion 340 is 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 jointly form a second threaded end, and an adjustment ring 360 is threadedly provided at the second threaded end.

[0049] Baffle plates 370 are formed on opposite sides of adjacent adjustment rings 360 , and a laying gap 420 for matching with the cable is formed between adjacent baffle plates 370 .

[0050] By cooperating with the second threaded end of the adjusting ring 360 and the baffle 370, the adjusting ring 360 can not only limit the position between the upper fixed shell 310 and the lower fixed shell 320, but also adjust the width of the laying gap 420 by rotating the adjusting ring 360, so that the laying gap 420 can limit the position of cables of different diameters, which not only improves the stability of the cable during laying, but also improves the transmission effect between the cable and the mounting part 140.

[0051] In this embodiment, grooves 530 are formed on the outer walls of the upper fixing shell 310 and the lower fixing shell 320 , rubber pads are formed in the grooves 530 , and adjacent grooves 530 together form a guide groove that cooperates with the bottom wall of the cable.

[0052] The setting of the guide groove can ensure that the cable moves along a predetermined path during the release process. The setting of the rubber pad increases the friction between the upper fixed shell 310 and the lower fixed shell 320 and the cable, ensuring the stability and continuity of the cable during the release process.

[0053] Example 3 See Figure 1 This embodiment provides a cable pay-off rack, which includes a horizontally arranged fixing portion 160 formed on the side wall of the rack body 150, and a low-voltage cable pay-off meter device as described in any one of Embodiment 1 or Embodiment 2 is provided on the top wall of the rack body 150.

[0054] Through the above structure, the device can be installed at any position, thereby improving the practicability of the device.

[0055] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
