Description

Technical Field

[0001] This utility model relates to the field of cable length measurement technology, and more specifically to a bracket device for rotary encoders. Background Technology

[0002] In the stranding process of superconducting cables, the high price of superconducting monofilaments or strands makes cost control of superconducting cables particularly important. Superconducting cables are delivered by length, and errors in length measurement will directly lead to increased costs and waste.

[0003] When cantilevered single-strand or cage-type twisters are used to strand superconducting monofilaments or strands, the length measurement is generally done using a traditional vertically placed wheel-type cable length counter. The weight of the measuring wheel or the weight of the superconducting cable causes friction between the superconducting cable and the measuring wheel during movement, which drives the measuring wheel to move synchronously. The measuring wheel drives the measuring wheel shaft to rotate synchronously, and the measuring wheel shaft drives the synchronous pulley mounted on the measuring wheel shaft to rotate. The synchronous pulley drives the synchronous pulley mounted on the mechanical length counter to rotate synchronously via a synchronous belt, thus achieving accurate mechanical length measurement of the superconducting cable.

[0004] An existing vertical cable meter is fitted with a rotary encoder featuring high precision, high reliability, fast tracking speed, resistance to high and low temperatures, waterproofing, dustproofing, resistance to corrosive gases, vibration resistance, and resistance to strong electromagnetic interference. This encoder measures the rotation angle of the metering wheel shaft, enabling accurate electronic metering of superconducting cables. By comparing the measurement with mechanical metering, the length of the superconducting cable during production can be tracked accurately and promptly, effectively reducing production costs. However, designing a suitable support structure for the rotary encoder to achieve accurate electronic metering of superconducting cables has remained a challenge for technical personnel at various cable companies.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] Please see Figure 1-4 The present invention provides the following technical solution: a bracket device for a rotary encoder, comprising a fixing ring 1, a groove 1.1, a through hole one 1.2, a through hole two 1.3, a through hole three 1.4, a rotary encoder 2, a large end of an extension shaft 2.1, a small end of an extension shaft 2.2, a platform 2.2.1, a nut 3, a screw one 4, a meter counting device cover plate 5, a meter counting wheel shaft 6, a synchronous pulley 7, a pressure cover 8, a connecting screw 9, a guide rod 9.1, a platform 9.1.1, a hexagonal head 9.2, an external thread 9.3, a flexible coupling 10, and a screw two 11.

[0020] The support device mainly consists of a fixing ring 1, multiple nuts 3, two screws 4, a connecting screw 9, and a flexible coupling 10.

[0021] The connecting screw 9 has a hexagonal head machined on its outer end for easy installation and disassembly. One end of the connecting screw 9 has an external thread 9.3, which is threaded to the central threaded hole of the measuring wheel shaft 6 to fasten the connecting screw 9 to the end face of the measuring wheel shaft 6. The other end of the connecting screw 9 has a smooth rod 9.1, and the end of the smooth rod 9.1 has a platform 9.1.1. By tightening the small internal hexagon countersunk head set screw on the flexible coupling 10 that rests on the platform 9.1.1, the flexible coupling 10 can be reliably fastened to the appropriate position of the smooth rod 9.1 of the connecting screw 9.

[0022] The fixing ring 1 is a hollow cylinder with a groove 1.1 and a through hole 1.3 machined inside, which are clearance fit with the small end 2.2 and the large end 2.1 of the extension shaft of the rotary encoder 2, respectively. Three through holes 1.2 are evenly machined on the circumference of the fixing ring 1, which coincide with the center lines of the three screw holes evenly distributed on the rotary encoder 2. By tightening the screws 11 that pass through the through holes 1.2 of the fixing ring 1 and are threaded into the screw holes of the rotary encoder 2, the rotary encoder 2 can be fastened to the end face of the groove 1.1 of the fixing ring 1. Two through holes 1.4 are also evenly machined on the circumference of the fixing ring 1, which are clearance fit with the external threads of the screws 4.

[0023] Two through holes are evenly machined on the meter counter cover plate 5. The two through holes are clearance-fitted with the external threads of screw 4. The two through holes on the meter counter cover plate 5 coincide with the center lines of the two through holes 1.4 on the fixing ring 1. By sequentially tightening the nuts 3 that are threaded to screw 4 and pass through the two through holes on the meter counter cover plate 5 and the fixing ring 1, the fixing ring 1, rotary encoder 2, flexible coupling 10 and multiple screws 11 can be fastened to the meter counter cover plate 5. If the meter counter cover plate 5 fastened to the vertical cable meter counter is a sealed type, the meter counter cover plate 5 can be removed first, screw 4 can be passed through it, and then the above operation can be performed. When replacing the above components next time, it is not necessary to remove the meter counter cover plate 5 from the vertical cable meter counter.

[0024] The through hole 1.2 of the fixing ring 1 should be at a certain angle to the through hole 1.4 to facilitate the installation and removal of the rotary encoder 2 and the connection of the wires of the electronic meter.

[0025] The small end 2.2 of the extended shaft of the rotary encoder 2 is machined with a platform 2.2.1. By tightening the small hexagonal countersunk head set screw on the flexible coupling 10 that rests on the platform 2.2.1, the flexible coupling 10 can be reliably fastened to the small end 2.2 of the extended shaft in a suitable position.

[0026] The synchronous pulley 7 is connected to the measuring wheel shaft 6 via a flat key. The pressure cap 8, which is pressed onto the synchronous pulley 7 by screws or connecting screws 9, limits the axial movement of the synchronous pulley 7.

[0027] As a further improvement of this utility model, if screw 4 is made of high-strength material and the two through holes uniformly machined on the meter measuring device cover plate 5 are locally reinforced, the rotary encoder 2 is less likely to produce eccentricity and angular error when measuring the rotation angle of the meter measuring wheel shaft, thereby further improving the stability and accuracy of the rotary encoder operation.

[0028] This utility model has a simple structure, is easy to manufacture, and is convenient to install, disassemble, and use. It has the advantages of being easy to promote and easy to install. By using this utility model, the rotary encoder installed on the bracket device will not produce eccentricity and angular error when measuring the rotation angle of the measuring wheel shaft, thereby realizing accurate electronic metering of the superconducting monofilament or strand being measured. By comparing with mechanical metering, the length of the superconducting monofilament or strand during the production process can be tracked in a timely and accurate manner, effectively reducing the production cost of superconducting cables.

[0032] 3. Assemble the fixing ring 1, rotary encoder 2 and screw 11 components according to the requirements of the rotary encoder bracket assembly drawing.

Machin the required through holes on the measuring device cover plate 5 according to the installation position requirements. Pass the screw 4 through the screw and the nut 3 and tighten it on the measuring device cover plate 5. Then install the measuring device cover plate 5 onto the vertical cable meter counter.

[0034] 5. Next, remove the screws of the clamping cover 8 from the shaft head of the measuring wheel 6 of the cable vertical meter counter. Then, screw the connecting screw 9 into the clamping cover 8 at the shaft head of the measuring wheel 6, and install the flexible coupling 10 onto the smooth rod 9.1 of the connecting screw 9 according to the installation position requirements.

[0035] 6. Next, assemble the fixed ring 1, rotary encoder 2 and screw 2 11 assembly with the flexible coupling 10, screw 1 4 and each nut 3 in sequence according to the installation position requirements.
