Description

Technical Field

[0001] This application relates to the field of distance measurement technology, and more specifically, to a movable distance measuring device. Background Technology

[0002] Steel plates are flat steel products made by pouring molten steel, cooling and pressing them. Steel plates can be classified according to their thickness as follows: thin steel plates <4mm (thinnest 0.2mm), thick steel plates 4-60mm, and extra-thick steel plates 60-115mm.

[0003] Currently, steel plates are usually sheared manually. During the shearing process, the steel plate needs to be marked with lines to record the shearing position and the length of the steel plate after shearing needs to be estimated by the naked eye. This results in a low yield of steel plates, and the length recorded manually deviates significantly from the national standard, increasing cutting losses and production costs. Utility Model Content

[0005] This application provides a movable ranging device, which adopts the following technical solution:

[0006] A movable ranging device includes a base, a drive mechanism, a bracket, an infrared rangefinder, and a line marker. The drive mechanism is mounted on the base and drives the bracket to reciprocate. The infrared rangefinder and the line marker are both mounted on the bracket.

[0007] Preferably, the driving mechanism includes a motor, a lead screw, a mounting plate, a slide rail, and a slider. The mounting plate and the slide rail are both disposed on the base. The motor is disposed on the mounting plate and drives the lead screw to rotate. The slider is threaded onto the lead screw and is mounted on the slide rail. The bracket is disposed on the slider.

[0008] Preferably, the drive mechanism further includes a first limiting block, which is disposed on the base and located at the end of the slide rail away from the motor. The first limiting block is rotatably connected to the lead screw.

The buffer mechanism includes a guide rod, a spring, and a second limiting block. The lower end of the guide rod is fixedly connected to the support plate, and the upper end of the guide rod is movably inserted through the support frame. The spring is sleeved on the guide rod and is located between the support plate and the support frame. The second limiting block is disposed at the upper end of the guide rod.

[0029] Example

[0030] like Figure 1-3 As shown in the embodiment of this application, the movable ranging device includes a base 1, a drive mechanism 2, a bracket 3, an infrared rangefinder 4, and a marking pen 5. The drive mechanism 2 is mounted on the base 1 and drives the bracket 3 to reciprocate. The infrared rangefinder 4 and the marking pen 5 are both mounted on the bracket 3.

[0031] During the production process, depending on the required steel plate length, the drive mechanism 2 drives the support 3 to the set position and the infrared rangefinder 4 measures the distance from that position to the shear blade of the rolling mill, thereby improving the position adjustment accuracy. When the strip is running, the scribing pen 5 automatically makes shearing marks on the surface of the strip. With the combined use of the infrared rangefinder 4 and the scribing pen 5, the length accuracy and yield of the steel plate shearing process are improved, human recording errors and steel plate cutting damage are reduced, and costs are saved.

[0032] In this embodiment, the drive mechanism 2 includes a motor 6, a lead screw 7, a mounting plate 8, a slide rail 9, and a slider 10. The mounting plate 8 and the slide rail 9 are both mounted on the base 1. The motor 6 is mounted on the mounting plate 8. The motor 6 drives the lead screw 7 to rotate. The slider 10 is threaded onto the lead screw 7. The slider 10 is mounted on the slide rail 9. The bracket 3 is mounted on the slider 10.

[0033] In use, the motor 6 drives the lead screw 7 to rotate in both directions. The rotation of the lead screw 7 causes the slider 10 to slide on the slide rail 9, thereby changing the position of the bracket 3 and changing the distance between the infrared rangefinder 4 and the shear blade of the rolling mill, thus adapting to the shearing needs of steel plates of different lengths.

[0034] In this embodiment, the drive mechanism 2 also includes a first limiting block 11, which is disposed on the base 1 and located at the end of the slide rail 9 away from the motor 6. The first limiting block 11 is rotatably connected to the lead screw 7. The first limiting block is used to limit the slider 10 and can also improve the stability of the first lead screw 7 during use.

[0035] In this embodiment, the bracket 3 includes a support rod 12, a crossbeam 13, a bearing frame 14, and a bearing plate 15. The support rod 12 is mounted on the slider 10, the crossbeam 13 is mounted on the support rod 12, the bearing frame 14 is mounted at the lower end of the crossbeam 13, the infrared rangefinder 4 is mounted on the bearing frame 14, and the marking pen 5 is mounted on the bearing plate 15. The bearing plate 15 is located below the bearing frame 14. A buffer mechanism 16 is provided between the bearing plate 15 and the bearing frame 14. The buffer mechanism 16 is used to buffer the force, preventing damage to the marking pen 5 while ensuring the marking effect.

[0036] In this embodiment, two sets of buffer mechanisms 16 are provided, and the two sets of buffer mechanisms 16 are respectively located on both sides of the marking pen 5. The buffer mechanism 16 includes a guide rod 17, a spring 18, and a second limiting block 19. The lower end of the guide rod 17 is fixedly connected to the bearing plate 15, and the upper end of the guide rod 17 is movably inserted through the bearing frame 14. The spring 18 is sleeved on the guide rod 17 and is located between the bearing plate 15 and the bearing frame 14. The second limiting block 19 is located at the upper end of the guide rod 17. When the marking pen 5 is subjected to force, the bearing plate 15 will squeeze the spring 18, and the spring 18 will be compressed, thereby achieving force buffering and preventing damage to the marking pen 5. Under the action of the spring 18's rebound force, the marking pen 5 is tightly attached to the surface of the steel plate, ensuring that the marking pen 5 makes a cutting mark on the steel plate.

[0037] In this embodiment, the support rod 12 includes a lower rod body 20, an upper rod body 21, and a locking member 22. The lower rod body 20 is mounted on the slider 10 and has a cavity. The lower end of the upper rod body 21 is movably installed in the cavity, and the upper end of the upper rod body 21 is fixedly connected to the crossbeam 13. During production, the height of the crossbeam 13 can be changed by moving the upper rod body 21 up and down. The change in the height of the crossbeam 13 causes the change in the height of the marking pen 5, thus adapting to the needs of steel plates of different thicknesses. When it is necessary to maintain or replace the infrared rangefinder 4 and the marking pen 5, the upper rod body 21 can be rotated without disassembling the base 1, improving the convenience of use. The locking member 22 is used to fix the upper rod body 21 on the lower rod body 20. In order to facilitate the tightening of the locking member 22, the locking member 22 adopts a Torx screw.

[0038] In this embodiment, a scale line 23 is provided on the upper rod 21. The scale line 23 can serve as an auxiliary reference when adjusting the height of the upper rod 21, thereby improving the adjustment speed.

[0039] In this embodiment, the lower rod 20 is welded to the slider 10.

[0040] In this embodiment, the support frame 14 is fixed to the crossbeam 13 by bolts 24. The use of bolts 24 for connection facilitates the assembly and disassembly of the support frame 14.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
