Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring equipment technology, specifically a roll gap measuring instrument. Background Technology
[0002] A roll gap measuring instrument, also known as a continuous casting machine condition detector, is a measuring device powered by a rechargeable battery and controlled by a computer. It is used to automatically measure the physical parameters of a continuous casting machine. Roll gap measuring instruments are widely used in steel mills, machining, construction, metallurgy, scientific research institutions, etc., and are characterized by high measurement and control accuracy, reliable performance, stable operation, and ease of use.
[0003] According to announcement number CN202903095U, a roll gap measuring device includes a measuring mechanism, a protective mechanism, a first frame, a sliding device, a second frame, and a receiving terminal. The measuring mechanism is installed inside the protective mechanism; the protective mechanism is fixedly connected to the first frame; the sliding device is fixedly connected to the second frame; the sliding device is sleeved on the outer wall of the protective mechanism and can slide relative to the protective mechanism; the receiving terminal receives the measured values from the measuring mechanism wirelessly. In actual operation, the measuring device is placed laterally between the roll gaps, with the first and second frames in contact with the roll wall. The hollow column and hollow shaft slide relative to each other due to the elastic pressure of the springs, which in turn acts on a dial indicator via a top shaft. The dial indicator transmits the measured displacement value to a first microprocessor, which converts the received displacement value into a digital signal and transmits it to a second microprocessor, which then displays the numerical information on a display.
[0004] The roll gap measuring device described above typically places the measuring instrument on the lower roll and adjusts the height of the measuring scale on the measuring instrument to measure the roll gap between the upper and lower rolls. When the distance between the roll gaps is small, it is impossible to fit the roll gap measuring instrument between the upper and lower rolls, resulting in the roll gap measuring instrument being unable to measure small roll gaps, thus reducing the measurement range of the roll gap measuring device. Therefore, we need to propose a roll gap measuring instrument. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: a roll gap measuring instrument, including a measuring shell 1, a measuring base plate 2 at the bottom of the measuring shell 1, a support structure 3 for supporting a measuring rod on the upper surface of the measuring base plate 2, an adjustment hole 4 at the top of the measuring shell 1, a measuring support tube 5 slidably inserted into the inner cavity of the adjustment hole 4, a positioning structure 6 for positioning the measuring height at the top of the measuring support tube 5, a measuring movable rod 7 in the inner cavity of the measuring support tube 5, a hidden groove on one side of the measuring shell 1, a measuring plate 8 in the inner cavity of the hidden groove, a connecting hole 9 on the surface of the measuring plate 8, the inner cavity of the connecting hole 9 slidably connected to the outer surface of the measuring support tube 5, and a rotating structure 10 for driving the measuring base plate 2 to rotate in the inner cavity of the measuring shell 1;
[0025] Pull down the measuring base plate 2 to pull it out of the measuring housing 1 and rotate it. Then pull the measuring support tube 5 out of the adjusting hole 4. Next, pick up the measuring plate 8 and put the connecting hole 9 on the measuring support tube 5 from bottom to top. Place the measuring support tube 5 on the measuring base plate 2 and position it through the support structure 3. Combine them into a simple small measuring tool. Make the measuring base plate 2 contact the lower roller and the measuring plate 8 contact the upper roller. Observe the position of the connecting hole 9 on the measuring support tube 5 to determine the thickness of the roll gap. This improves the measuring range of the roll gap measuring device and allows the measuring device to measure smaller roll gaps.
[0026] The support structure 3 includes a fixed tube 31, and reinforcing rods 32 are fixedly connected to all four sides of the fixed tube 31. The other end of the reinforcing rods 32 is fixedly connected to the upper surface of the measuring base plate 2. The measuring support tube 5 is inserted into the fixed tube 31, and the bottom end of the measuring support tube 5 is supported by the cooperation of the fixed tube 31 and the reinforcing rods 32.
[0027] The positioning structure 6 includes a positioning tube 61, which is fixedly connected to the top end of the measuring support tube 5. The surface of the positioning tube 61 is provided with a threaded hole, and a locking bolt 62 is threadedly connected to the inner cavity of the threaded hole. One end of the locking bolt 62 is in contact with the surface of the measuring movable rod 7. By rotating the locking bolt clockwise, the locking bolt can be moved toward the surface of the measuring movable rod 7. The locking bolt, through the frictional force on the measuring movable rod 7, positions the measuring movable rod 7 in the adjusted position within the measuring support tube 5.
[0028] The outer wall of the measuring rod 7 is provided with a support groove 11. One end of the locking bolt 62 is slidably connected to the inner cavity of the support groove 11. The support groove 11 and the locking bolt 62 cooperate to prevent the angle of the measuring rod 7 from shifting when it is raised or lowered.
[0029] The rotating structure 10 includes a movable tube 101, which is located at the bottom of the measuring housing 1. One end of the movable tube 101 extends into the inner cavity of the measuring housing 1. A rotating rod 102 is movably connected to the inner cavity of the movable tube 101. The bottom end of the rotating rod 102 is fixedly connected to the upper surface of the measuring base plate 2. A limit block 103 is fixedly connected to the top end of the rotating rod 102. Pulling the measuring base plate 2 downward causes the rotating rod 102 to move downward, and then the angle of the measuring base plate 2 is adjusted by rotation.
[0030] A support spring 12 is sleeved on the outer surface of the rotating rod 102. The support spring 12 is set in the inner cavity of the measuring housing 1. The support spring 12 is located between the limiting block 103 and the inner side wall of the measuring housing 1. The support spring 12 provides support force to the limiting block 103, so that the support spring 12 pushes the limiting block 103 to move upward. The limiting block 103 drives the measuring base plate 2 to move upward through the rotating rod 102, which facilitates the storage of the measuring base plate 2.
[0031] The lower surface of the measuring housing 1 is provided with a placement groove 13. The inner cavity of the placement groove 13 is engaged with the surface of the measuring base plate 2. By setting the placement groove 13, the measuring base plate 2 can be tucked in, which increases the overall aesthetics of the measuring housing 1.
[0032] The outer wall of the measuring housing 1 has a slot, and a bubble level 14 is installed in the inner cavity of the slot. When the measuring housing 1 measures a normal-sized roll gap, the bubble level 14 can help the measuring housing 1 to level itself and find a horizontal position.
[0033] In practical use: During normal measurement, place the measuring housing 1 on the lower roller, level it, and then pull the measuring movable rod 7 to move inside the measuring support tube 5. After the top of the measuring movable rod 7 contacts the upper roller, turn the locking bolt 62 clockwise to lock the measuring movable rod 7. Then observe the scale line to realize the roller gap measurement.
[0034] When measuring a small roll gap, pull down the measuring base plate 2 to pull it out of the measuring housing 1 and rotate it. Then, pull the measuring support tube 5 out of the adjusting hole 4. Next, pick up the measuring plate 8 and put the connecting hole 9 on the measuring support tube 5 from bottom to top. Then, insert the measuring support tube 5 into the fixing tube 31. The bottom end of the measuring support tube 5 is supported by the cooperation of the fixing rod and the reinforcing rod 32. The measuring base plate 2 contacts the lower roller, and the measuring plate 8 contacts the upper roller. By observing the position of the connecting hole 9 on the measuring support tube 5, the thickness of the roll gap can be obtained, thus realizing the measurement of small roll gaps. This improves the measurement range of the roll gap measuring device, allowing the measuring device to measure smaller roll gaps.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
