Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cable production auxiliary equipment, and in particular relates to a non-contact cable outer diameter measuring support device. Background Technology
[0002] In the cable production process, to ensure cable quality, outer diameter measuring devices need to be installed before and after multiple workstations on the production line. This involves deploying a laser diameter gauge on both sides of the workstation using a bracket with pre-calculated height and tilt angle to monitor changes in the cable's outer diameter before and after entering and leaving the workstation. Currently, non-contact measurement methods like laser diameter gauges are generally used. Their advantages include no need for clamping, avoiding any impact on the cable's radial dimensions, and high detection accuracy. However, when the production line is adjusted, changes in some workstations may cause the original laser diameter gauge bracket to become difficult to adapt to the new height and tilt requirements. This necessitates the fabrication of brackets that meet the requirements, making it difficult to respond promptly to production line adjustments and resulting in poor deployment flexibility. Summary of the Invention
[0003] To overcome the technical problems described in the background section, this utility model provides a non-contact cable outer diameter measuring support device. The commonly used single telescopic rod bracket is replaced with a four telescopic rod bracket, which has higher stability. Furthermore, a structure with a load-bearing plate that can be flipped and adjusted forward and backward is set on the four telescopic rod bracket, which can quickly adjust the forward and backward tilt angle of the laser diameter gauge. When adjusting at certain workstations on the production line, there is no need to specially process brackets of corresponding heights, which helps to flexibly deploy the laser diameter gauge to measure the outer diameter of the cable.
[0004] The technical solution of this utility model is as follows: a non-contact cable outer diameter measuring support device, including a bearing plate, an adjusting elongated hole, an upper locking bolt, a rotating insert, a rotating shaft, a rotating sleeve, an adjustable telescopic rod, and a base. The upper end face of the bearing plate is used to support and connect a laser diameter measuring instrument. The bearing plate has a rectangular straight plate structure and an adjusting elongated hole extending from front to back is provided at each of the four corners. The threaded part of the upper locking bolt is embedded in the adjusting elongated hole from top to bottom. The lower end of the upper locking bolt is threaded and nested with a rotating insert. The projection of the lower end of the rotating insert on the left viewing plane is a semi-circular ring structure and nested with a rotating sleeve. The rotating shaft is embedded in the fitting part of the rotating sleeve and the rotating insert from left to right, so that the rotating insert can rotate back and forth relative to the rotating sleeve. An adjustable telescopic rod is fixedly provided at the lower end of the rotating sleeve, and a base that can be connected to the factory floor by a ground bolt is fixedly provided at the lower end of the adjustable telescopic rod.
[0005] Furthermore, a vertical laser diameter gauge is pressed against the upper surface of the support plate. The center of the support plate has several connecting through holes that are concentric with the connecting holes at the bottom of the laser diameter gauge. Fixing bolts are installed on the lower surface of the support plate through the connecting through holes from bottom to top. The bolt portion of the fixing bolt is threaded into the laser diameter gauge, so that the laser diameter gauge and the support plate are locked together relatively and fixedly.
[0006] Furthermore, the adjustable telescopic rod includes a telescopic rod body, a lateral locking bolt, and a telescopic sleeve. The upper end of the telescopic rod body is fixedly installed at the lower end of the rotating sleeve. The telescopic rod body extends vertically downward and is nested in the lower part with a telescopic sleeve. The lateral locking bolt is threaded into the outer wall of the upper end of the telescopic sleeve. The end of the lateral locking bolt that extends into the telescopic sleeve abuts against the outer wall of the telescopic rod body. A base is fixedly installed at the lower end of the telescopic sleeve.
[0007] Furthermore, the base includes a base plate, ground bolt holes, and X-shaped reinforcing ribs. The base plate has a rectangular horizontal plate structure and ground bolt holes for ground bolt connection are provided at the four corners. Four rectangular telescopic sleeves are fixedly installed in the middle of the base plate, and X-shaped reinforcing ribs are provided between the telescopic sleeves.
[0008] The beneficial effects of adopting the above technical solution are as follows: By replacing the commonly used single telescopic rod bracket with a four telescopic rod bracket, the stability of this utility model is higher. Furthermore, a structure that can flip and adjust the bearing plate on the top of the four telescopic rod bracket can quickly adjust the tilt angle of the laser diameter gauge. When adjusting at certain workstations on the production line, there is no need to specially process brackets of corresponding heights, which helps to flexibly deploy the laser diameter gauge to measure the outer diameter of cables.

[0015] Example 1: As Figures 1-5 As shown, this utility model provides a non-contact cable outer diameter measurement support device, including a bearing plate 2, a pitch angle adjustment structure, an adjustable telescopic rod, and a base. The bearing plate 2, the pitch angle adjustment structure, the adjustable telescopic rod, and the base are all made of steel. A vertical laser diameter gauge 1 is pressed against the upper end surface of the bearing plate 2. The center of the bearing plate 2 has four connecting through holes that are concentric with the connecting holes at the bottom of the laser diameter gauge 1. A fixing bolt 14 is provided on the lower end surface of the bearing plate 2 from bottom to top through the connecting through holes. The bolt part of the fixing bolt 14 is threaded into the laser diameter gauge 1, so that the laser diameter gauge 1 and the bearing plate 2 are relatively fixedly locked together. The bearing plate 2 has a rectangular straight plate structure and a pitch angle adjustment structure is provided at each of the four corners. An adjustable telescopic rod for adjusting the height of the laser diameter gauge 1 off the ground is fixedly provided at the lower end of the pitch angle adjustment structure. A base that can be connected to the factory floor by a ground bolt is fixedly provided at the lower end of the adjustable telescopic rod.
[0016] Among them, such as Figure 4 As shown, the pitch angle adjustment structure includes an adjustment elongated hole 3, an upper locking bolt 13, a rotating insert 12, a rotating shaft 11, and a rotating sleeve 10. The four corners of the bearing plate 2 are drilled with adjustment elongated holes 3 extending from front to back. The threaded part of the upper locking bolt 13 is embedded in the adjustment elongated hole 3 from top to bottom. The lower end of the upper locking bolt 13 is threaded and nested with the rotating insert 12. The projection of the lower end of the rotating insert 12 on the left viewing plane is a semi-circular ring structure and nested with the rotating sleeve 10. The rotating shaft 11 is embedded from left to right in the fitting part of the rotating sleeve 10 and the rotating insert 12, forming a hinge-like structure, so that the rotating insert 12 can rotate back and forth relative to the rotating sleeve 10. An adjustable telescopic rod is welded to the lower end of the rotating sleeve 10.
[0017] The adjustable telescopic rod includes a telescopic rod body 4, a lateral locking bolt 5, and a telescopic sleeve 6. The upper end of the telescopic rod body 4 is welded to the lower end of the rotating sleeve head 10. The telescopic sleeve 6 is nested on the lower end of the telescopic rod body 4, which is vertically downward. The lateral locking bolt 5 is threaded into the outer wall of the upper end of the telescopic sleeve 6. The end of the lateral locking bolt 5 that extends into the telescopic sleeve 6 abuts against the outer wall of the telescopic rod body 4. A base is welded to the lower end of the telescopic sleeve 6.
[0018] The base includes a base plate 7, ground bolt holes 8, and X-shaped reinforcing ribs 9. The base plate 7 has a rectangular horizontal plate structure and ground bolt holes 8 with through holes at the four corners for ground bolt connection. Four rectangular telescopic sleeves 6 are welded to the middle of the base plate 7, and X-shaped reinforcing ribs 9 are provided between the telescopic sleeves 6 to enhance the stability of the four telescopic sleeves 6.
[0019] Operating Instructions: When adjusting certain workstations on the production line, there is no need to disassemble or replace this support part of the laser diameter gauge 1. If height adjustment is required, first loosen the side locking bolts 5 with a wrench, then stretch or press down the telescopic rod 4 relative to the telescopic sleeve 6 to the desired position, that is, adjust the height of the lower end of the bearing plate 2 relative to the upper end of the telescopic sleeve 6. Then temporarily tighten the side locking bolts 5. Use a simulated cable with counterweights attached to both ends to stretch between the two workstations before and after the current measurement station. Observe the position of the simulated cable in the measurement area of the laser diameter gauge 1. If it is within the measurement area and close to the center of the measurement area, it can be considered to meet the requirements. At this time, the side locking bolts 5 can be tightened with a wrench. Otherwise, one person holds the bearing plate 2 while another person uses a wrench to readjust the extension height of the telescopic rod 4 relative to the telescopic sleeve 6. Then tighten all the side locking bolts 5. If it is necessary to adjust the tilt angle of the laser diameter measuring instrument 1, the upper locking bolt 13 and the side locking bolt 5 need to be loosened but not detached. Use a simulated cable with counterweights tied to both ends to stretch between the two stations in front and behind the current measurement station. One person supports the bearing plate 2 and positions it at the predetermined tilt angle, while the other person uses a wrench to tighten the upper locking bolt 13 and the side locking bolt 5 in turn. In the above adjustment process, since the commonly used single telescopic rod bracket is changed to a four telescopic rod bracket, the stability is higher. Moreover, a structure that can flip and adjust the bearing plate 2 is set above the four telescopic rod brackets, which can quickly adjust the front and rear tilt angle of the laser diameter measuring instrument 1. When adjusting at some stations on the production line, there is no need to specially process the bracket of the corresponding height, which helps to flexibly deploy the laser diameter measuring instrument 1 to measure the outer diameter of the cable.
