Description

Technical Field

[0001] This utility model relates to the field of conductor resistance measurement, and in particular to an adjustment device for conductor resistance measurement. Background Technology

[0002] A conductor is a substance with very low resistivity that easily conducts electric current. Cable conductors, in particular, are wires made by stranding conductors with high conductivity together and then encasing them in an insulating layer, used for power and signal transmission. After cable conductor production, their resistance needs to be measured to ensure the produced cables meet usage requirements, preventing excessive power loss due to high resistance, and avoiding overheating of the conductor after prolonged use that could accelerate insulation aging and pose safety hazards. However, in cable conductor production lines, the measurement space for the cable conductors is complex. While conventional cable conductor resistance measuring devices can be height-adjusted, they cannot adjust the depth in front of or behind the device. This means that obstacles placed near the device can affect its normal operation. Furthermore, the larger the diameter of the cable conductor being measured, the greater the tilt angle required during measurement. Existing cable conductor resistance measuring devices cannot adjust the tilt angle according to the wire size, leading to limitations in measuring cable conductor resistance. Therefore, an adjustment device for conductor resistance measurement is needed to solve these problems. Utility Model Content

[0003] In view of the above situation and to overcome the shortcomings of the prior art, this device provides an adjustment device for measuring conductor resistance. This device can adjust the front and rear position and height of the cable conductor resistance measuring device according to the site conditions to meet the needs of cable conductor resistance measurement. At the same time, the device can adjust the tilt angle of the cable conductor resistance measuring device, so that the device can measure the resistance value of cable conductors of various sizes, thereby improving the applicability of the device.

[0024] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0025] according to Figures 1 to 7 As shown, according to Figures 1 to 4 As shown, an adjustment device for measuring conductor resistance includes a constant temperature box 1. A lifting assembly 2 is connected to the rear end of the constant temperature box 1. The lifting assembly 2 includes two symmetrically arranged lifting mechanisms 3. A connecting shell 4 is connected between the two lifting mechanisms 3. The two lifting mechanisms 3 control the lifting of the connecting shell 4 synchronously. A telescopic assembly 5 is fixedly connected to the top of the connecting shell 4. A rotating assembly 6 is fixedly connected to the front end of the telescopic assembly 5. The front end of the rotating assembly 6 is fixedly connected to the rear end of the constant temperature box 1.

[0026] The rotating component 6 includes a third drive motor 64, which is fixedly connected to the top surface of the front end of the telescopic component 5. The output end of the third drive motor 64 extends to the outside of the front end of the telescopic component 5. A drive gear 62 is fixedly connected to one end of the output end of the third drive motor 64 that extends to the outside of the front end of the telescopic component 5. A rotating gear 61 meshes with the top of the drive gear 62. The rotating gear 61 is rotatably connected to the rotating shaft 63 fixedly connected to the front end of the telescopic component 5. The rotating gear 61 is fixedly connected to the rear end of the constant temperature box 1.

[0027] In specific implementation, the constant temperature box 1 can adopt a constant temperature water bath device for measuring the resistance of wires and cables, which is authorized by publication number CN220403639U. Using technology with the same principle as that patent, the temperature inside the constant temperature box 1 is maintained at a suitable temperature for measuring the cable conductor. Clamping devices for holding the cable conductor are fixedly connected to both sides of the constant temperature box 1. The lifting component 2 includes two lifting mechanisms 3 with the same structure. The two lifting mechanisms 3 are respectively connected to the connecting shell 4. The connecting shell 4 can be set as U-shaped. The telescopic component 5 is set on the top of the connecting shell 4. The two sides of the connecting shell 4 are respectively connected to the two lifting mechanisms 3. The lifting and lowering of the connecting shell 4 is controlled synchronously by the two lifting mechanisms 3. When the connecting shell 4 is lifted and lowered, the telescopic component 5 is driven to lift and lower, thereby adjusting the height of the constant temperature box 1 set at the front end of the telescopic component 5. The telescopic component 5 is set on the top of the connecting shell 4. The telescopic component 5 can control the front and rear position of the constant temperature box 1, thereby avoiding the problem of being unable to measure the cable conductor due to obstacles near the measuring device.

[0028] When it is necessary to adjust the tilt angle of the constant temperature box 1, the drive gear 62 set at the front end of the telescopic component 5 is rotated by the third drive motor 64. The rotating drive gear 62 drives the meshing rotating gear 61 to rotate. Since the front end of the rotating gear 61 is fixedly connected to the rear end of the constant temperature box 1, and the rear end of the rotating gear 61 is rotatably connected to the telescopic component 5, the rotating gear 61 can drive the constant temperature box 1 to rotate synchronously, thereby adjusting the tilt angle of the constant temperature box 1. This allows the constant temperature box 1 to adjust its tilt angle according to the cable conductor to be measured, so as to meet the appropriate measurement environment.

[0029] Furthermore, two angle limiting blocks 65 are fixedly connected to the front end of the telescopic component 5. The two angle limiting blocks 65 limit the maximum tilt angle when the rotating component 6 controls the angle adjustment of the constant temperature box 1.

[0030] In practical implementation, two angle limiting blocks 65 are fixedly connected to the front end of the telescopic component 5. The two angle limiting blocks 65 are respectively provided with chamfers on one side. The two angle limiting blocks 65 are used to limit the rotation of the thermostatic box 1 to the maximum angle when the rotating component 6 controls the thermostatic box 1 to rotate, so as to avoid the thermostatic box 1 tilting too much due to the rotating component 6 controlling the thermostatic box 1 to tilt or the device to be damaged, thereby improving the safety of the device.

[0031] Furthermore, the lifting mechanism 3 includes a column 31, a top plate 38 fixedly connected to the top of the column 31, a first drive motor 32 fixedly connected to the bottom inner side of the column 31, a first lead screw 33 fixedly connected to the output end of the first drive motor 32, the top end of the first lead screw 33 being rotatably connected to the top plate 38, a first lead screw sleeve 34 fixedly connected to both sides of the connecting shell 4, the connecting shell 4 being threadedly connected to the corresponding first lead screw 33 through the first lead screw sleeves 34 on both sides, longitudinal guide rails 35 being provided on both sides of the first lead screw 33, the longitudinal guide rails 35 being fixedly connected to the inner side of the column 31, and longitudinal sliders 36 being provided on both sides of the first lead screw sleeves 34, the longitudinal sliders 36 being fixedly connected to the connecting shell 4, and the longitudinal sliders 36 being slidably connected to the corresponding longitudinal guide rails 35.

[0032] In specific implementation, the top end of the first lead screw 33 is rotatably connected to the bottom end of the top plate 38. Longitudinal guide rails 35 are fixedly connected to the surfaces of the columns 31 on both sides of the first lead screw 33. A first lead screw sleeve 34, which is threadedly connected to the first lead screw 33, is fixedly connected to the outside of the connecting shell 4 on both sides of the first lead screw sleeve 34. Longitudinal sliders 36, which slide in cooperation with the two longitudinal guide rails 35, are fixedly connected to the outside of the connecting shell 4 on both sides of the first lead screw sleeve 34. The two first drive motors 32 in the two lifting mechanisms 3 can be controlled by a synchronous controller. The synchronous controller can synchronously control the rotation direction and rotation speed of the two first drive motors 32, which improves the stability of the lifting control of the connecting shell 4 by the two lifting mechanisms 3. In use, the first drive motor 32 controls the rotation of the first lead screw 33. The rotating first lead screw 33 controls the synchronous lifting of the connecting shell 4 through the first lead screw sleeve 34. The setting of the longitudinal guide rails 35 and the longitudinal sliders 36 can limit the longitudinal movement direction of the connecting shell 4, which improves the stability of the lifting of the connecting shell 4.

[0033] Furthermore, an extreme lifting limit block 39, which limits the extreme lifting height of the connecting shell 4, is fixedly connected to the surface of the column 31 at the top of the first drive motor 32.

[0034] In specific implementation, the output end of the first drive motor 32 passes through the lifting limit block and is fixedly connected to the bottom end of the first lead screw 33. The top plate 38 at the top of the column 31 and the limit lifting limit block 39 at the top of the first drive motor 32 limit the upward or downward distance of the connecting shell 4, so as to prevent the lifting assembly 2 from controlling the lifting height of the connecting shell 4 to be too high or too low, causing the bottom of the constant temperature box 1 to contact the ground, thereby causing damage to the constant temperature box 1.

[0035] Furthermore, the telescopic component 5 includes a second drive motor 51, which is fixedly connected to the top surface of the rear end of the connecting shell 4. A second lead screw 52 is fixedly connected to the output end of the second drive motor 51. A square bearing 53 is rotatably connected to the other end of the second lead screw 52. The bottom end of the square bearing 53 is fixedly connected to the top surface of the connecting shell 4. A second lead screw sleeve 58 is threadedly connected to the surface of the second lead screw 52. A telescopic plate 54 is fixedly connected to the top of the second lead screw sleeve 58. Side plates 55 are fixedly connected to both sides of the telescopic plate 54. Transverse guide rails 56 are fixedly connected to the outer sides of the side plates 55. Transverse sliders 57 that slide in cooperation with the transverse guide rails 56 are fixedly connected to the inner side of the connecting shell 4. The transverse sliders 57 are slidably connected to the corresponding transverse guide rails 56.

[0036] In practical implementation, the telescopic component 5 can adjust the front and rear depth of the thermostatic box 1 to avoid obstacles near the thermostatic box 1, so that the device can complete the measurement of the resistance value of the cable conductor even in complex environments. The telescopic plate 54 is provided with a front baffle at the front end and side plates 55 on both sides respectively. The output end of the third drive motor 64 passes through the front baffle and is fixedly connected to the drive gear 62. At the same time, the rotating shaft 63 is provided on the front surface of the front baffle, and the rotating gear 61 is fixedly connected to the rotating shaft 63 on the same axis. The front baffle can provide installation space for the drive gear 62 and the rotating gear 61, so that the rotating component 6 can control the thermostatic box 1 to adjust the angle.

[0037] The second drive motor 51 controls the second lead screw 52 to rotate forward or backward. The rotating second lead screw 52 controls the telescopic plate 54 to move forward or backward on the top of the connecting shell 4 through the second lead screw sleeve 58 set at the bottom of the telescopic plate 54. The front and back positions of the thermostatic box 1 can be adjusted by moving the telescopic plate 54 forward and backward, which facilitates the adjustment of the front and back positions of the thermostatic box 1. The outer sides of the side plates 55 on both sides of the telescopic plate 54 are respectively fixedly connected to the transverse guide rails 56. The inner walls on both sides of the connecting shell 4 are respectively fixedly connected to the transverse sliders 57 that slide in cooperation with the transverse guide rails 56. The sliding cooperation between the transverse guide rails 56 and the transverse sliders 57 can facilitate the telescopic plate 54 to slide back and forth on the connecting shell 4, and at the same time provide a certain load support for the telescopic plate 54, improve the load capacity of the device, and increase the stability of the telescopic plate 54 sliding back and forth.

[0038] Furthermore, dust removal brushes 37 are fixedly connected to the outer side of the connecting shell 4 at corresponding positions to the longitudinal guide rail 35.

[0039] In practice, the brush heads of the dust removal brush 37 are respectively set towards the longitudinal guide rail 35. The dust removal brush 37 can be used to brush away the dust on the surface of the longitudinal guide rail 35 when the lifting mechanism 3 controls the connecting shell 4 to move up and down, thereby improving the smoothness of the sliding of the connecting shell 4 on the surface of the longitudinal guide rail and preventing the dust attached to the surface of the longitudinal guide rail 35 from increasing the friction between the longitudinal slider 36 and the longitudinal guide rail 35.

[0040] Furthermore, telescopic limiting blocks 59 corresponding to the transverse guide rail 56 are fixedly connected to the top of the front and rear ends of the connecting shell 4, respectively.

[0041] In practical implementation, the telescopic limiting block 59 is fixedly connected to the front end of the top of the connecting shell 4, and the rear end of the telescopic limiting block 59 is in contact with the transverse guide rail 56. The telescopic limiting block 59 can limit the telescopic plate 54 to the extreme position of the front end of the connecting shell 4, so as to prevent the telescopic plate 54 from detaching from the connecting shell 4 due to excessive forward telescopic distance, which would cause damage to the device and improve the safety of the device.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
