Description

Technical Field

[0001] This utility model relates to a convenient rolling mill archway window accuracy measurement device, belonging to the technical field of rolling mill archway window accuracy measurement. Background Technology

[0002] During hot rolling production, the harsh operating conditions of the rolling mill makeshift windows are easily affected by cooling water corrosion and impact wear, leading to a decrease in window accuracy. Failure to adjust the window accuracy in a timely manner will significantly impact the stability of the rolling mill and product quality. Therefore, the window accuracy needs to be tested before adjustment. Currently, most manufacturers use laser tracking instruments to test the accuracy of rolling mill makeshift windows. While this method offers high accuracy, it requires equipment preheating and testing by a professional testing agency, resulting in high costs and low efficiency.

[0003] To address this issue, our company developed a simple and easy-to-use precision detection device for rolling mill archway windows, with authorization announcement number CN221612016U. While this effectively solves the problems of complex structure and low detection efficiency, in actual use, to ensure that the measuring point is located on the plane formed by the support rod and the plumb line to guarantee measurement accuracy, a reference line needs to be drawn on the rolling mill archway window before the measuring ruler can be used for measurement. Therefore, the measurement efficiency remains relatively low. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a convenient rolling mill archway window accuracy measuring device that can effectively improve measurement efficiency.

[0005] The present invention relates to a convenient rolling mill archway window precision measuring device, which includes a support assembly, a rope seat connected to the support assembly, a plumb line connected to the rope seat, a lead weight fixedly connected to the lower end of the plumb line, a laser head fixing seat fixedly connected to the support assembly, and a laser line emitter installed on the laser head fixing seat.

[0006] Furthermore, the device also includes a windproof container, inside which the plumb bob rests after it hangs naturally. By adding a viscous liquid such as oil into the windproof container, the plumb bob can be effectively prevented from swinging, thus ensuring the verticality of the plumb line and improving measurement accuracy.

[0007] Furthermore, there are two laser head mounting bases, each equipped with a laser line emitter, which points to the left and right sides of the support assembly, respectively. The two laser line emitters can emit laser lines to both sides of the rolling mill stand's window, thus enabling separate measurements to be taken from both sides of the window with a single installation.

[0008] Furthermore, the support assembly includes a fixed support, on which a support rod is fixedly connected. A movable support is threadedly connected to the end of the support rod, and the laser head mounting base is connected to the support rod. By supporting the fixed support on one side of the rolling mill stand's window, and then rotating the movable support, under the action of the threaded connection, the movable support will move to the other side of the rolling mill stand's window, thus providing stable support for the plumb bob on the other side of the window.

[0009] Furthermore, this device also includes an electronic digital vernier caliper, which can display measurement data and effectively improve measurement efficiency.

[0010] Furthermore, the electronic digital vernier caliper has a data transmission function. Two adjusting seats are slidably connected to the support rod, and each adjusting seat is threaded with a set screw corresponding to the support rod. An adjusting shaft connects the two adjusting seats, and the rope seat is connected to the adjusting shaft. By sliding the adjusting seats and locking them with the set screws, the rope seat can be adjusted to the exact center of the window in the rolling mill stand. Moreover, the electronic digital vernier caliper can transmit measurement data in real time to a computer, mobile phone, or data acquisition system, facilitating the collection and recording of measurement data.

[0011] Furthermore, the adjusting shaft is provided with an external thread, and the rope seat is threadedly connected to the adjusting shaft. Through the threaded engagement, the position of the rope seat can be finely adjusted, thereby ensuring the accuracy of the rope seat's position.

[0012] Furthermore, a knob is fixedly connected to the rope seat for easy adjustment.

[0013] Furthermore, the support rod is equipped with a battery compartment containing a battery, and the laser line emitter is electrically connected to the battery. By integrating the power supply, no external power source is required, thus simplifying the structure.

[0014] Furthermore, the two poles of the battery are respectively connected to a first wire and a second wire. A switch and an indicator light are connected to the first wire. The end of the first wire is electrically connected to the measuring scale of the electronic digital vernier caliper, and the end of the second wire is electrically connected to a plumb line. Both the plumb line and the measuring scale are made of conductive material. A third wire connects the first and second wires, and the laser emitter is connected to the third wire. During measurement, the indicator light circuit is activated and illuminated when the measuring scale contacts the plumb line, ensuring that the measuring scale makes precise contact with the plumb line and effectively improving measurement accuracy.

[0015] Furthermore, the support rod is a hollow rod with wire holes on its side wall, which allows some of the wires to be stored inside the support rod, making the structure simpler.

[0016] Furthermore, the switch can be mounted on the support rod, making the structure more compact.

[0017] Furthermore, the indicator light can be set on the vernier scale of the electronic digital display vernier caliper, which not only makes the structure compact, but also makes it easy to observe the status of the indicator light during measurement.

[0018] The advantages of this utility model compared with the prior art are:

[0019] The convenient rolling mill archway window accuracy measuring device described in this utility model is equipped with a laser line emitter, which can emit laser lines to the side of the rolling mill archway window, thereby eliminating the need for workers to hand-draw reference lines and effectively improving measurement efficiency.

[0028] like Figure 1 , Figure 2As shown, the convenient rolling mill archway window precision measuring device of this utility model includes a support component 1, a rope seat 4 connected to the support component 1, a plumb line 5 connected to the rope seat 4, a lead weight 6 fixedly connected to the lower end of the plumb line 5, a laser head fixing seat 2 fixedly connected to the support component 1, and a laser line emitter 3 installed on the laser head fixing seat 2.

[0029] In use, the rope seat 4 is fixedly connected to the inner side of the upper end of the window of the rolling mill stand 7 through the support component 1. Under the action of the plumb bob 6, the plumb line 5 hangs down naturally, thus serving as a reference line. Through the laser line emitter 3, the laser line 10 can be emitted to the side of the window of the rolling mill stand 7. The vertical distance from the laser line 10 to the plumb line 5 is measured by the measuring ruler, and the window accuracy of the rolling mill stand can be obtained. During the measurement process, there is no need for workers to draw reference lines by hand, which effectively improves the measurement efficiency.

[0030] Example 2:

[0031] like Figure 1 , Figure 2 As shown, based on Embodiment 1, this device further includes a windproof barrel 9, in which the plumb bob 6 hangs naturally and is located. By adding a viscous liquid such as oil into the windproof barrel 9, the plumb bob 6 can be effectively prevented from swinging, thereby ensuring the verticality of the plumb line 5 and improving measurement accuracy.

[0032] Furthermore, there are two laser head mounting bases 2, each equipped with a laser line emitter 3, which points to the left and right sides of the support assembly 1, respectively. The two laser line emitters 3 can emit laser lines 10 to both sides of the window of the rolling mill stand 7, thus enabling measurements to be taken on both sides of the window of the rolling mill stand 7 with a single installation.

[0033] Example 3:

[0034] like Figures 1 to 4 As shown, based on Embodiment 1 or Embodiment 2, the support assembly 1 further includes a fixed support 11, a support rod 12 fixedly connected to the fixed support 11, and a movable support 15 threadedly connected to the end of the support rod 12. The laser head mounting base 2 is connected to the support rod 12. By supporting the fixed support 11 on one side of the window of the rolling mill stand 7, and then rotating the movable support 15, the movable support 15 will move to the other side of the window of the rolling mill stand 7 under the action of the threaded connection, thereby supporting the other side of the window of the rolling mill stand 7, thus completing the stable support for the lead weight 6.

[0035] Furthermore, this device also includes an electronic digital display vernier caliper 8, which can display measurement data and effectively improve measurement efficiency.

[0036] Furthermore, the electronic digital display vernier caliper 8 has a data transmission function. Two adjusting seats 41 are slidably connected to the support rod 12. Each adjusting seat 41 is threaded with a set screw 42 corresponding to the support rod 12. An adjusting shaft 44 connects the two adjusting seats 41, and the rope seat 4 is connected to the adjusting shaft 44. By sliding the adjusting seats 41 and locking them with the set screws 42, the rope seat 4 can be adjusted to the center of the window in the rolling mill stand 7. Moreover, the electronic digital display vernier caliper 8 can transmit measurement data in real time to a computer, mobile phone, or data acquisition system, facilitating the collection and recording of measurement data.

[0037] Furthermore, the adjusting shaft 44 is provided with an external thread, and the rope seat 4 is threadedly connected to the adjusting shaft 44. Through the threaded engagement, the position of the rope seat 4 can be finely adjusted, thereby ensuring the positional accuracy of the rope seat 4.

[0038] Furthermore, a knob 43 is fixedly connected to the rope seat 4 to facilitate the adjustment of the rope seat 4.

[0039] Example 4:

[0040] like Figures 1 to 5 As shown, based on Embodiment 3, the support rod 12 is further provided with a battery compartment 13, in which a battery is installed, and the laser line emitter 3 is electrically connected to the battery. By integrating the power supply, there is no need to connect to an external power source, thus simplifying the structure.

[0041] Furthermore, the two poles of the battery are respectively connected to a first wire 17 and a second wire 16. A switch 14 and an indicator light 18 are connected to the first wire 17. The end of the first wire 17 is electrically connected to the measuring scale 83 on the electronic digital vernier caliper 8. The end of the second wire 16 is electrically connected to a plumb line 5. Both the plumb line 5 and the measuring scale 83 are made of conductive material. A third wire 19 connects the first wire 17 and the second wire 16, and the laser emitter 3 is connected to the third wire 19. During measurement, the vernier scale 82 slides on the main scale 81 of the electronic digital vernier caliper 8, and the measuring scale 83 contacts the plumb line 5. This activates the circuit of the indicator light 18, causing it to illuminate. This ensures that the measuring scale 83 is in perfect contact with the plumb line 5, effectively improving measurement accuracy.

[0042] Furthermore, the support rod 12 is a hollow rod, and the side wall of the support rod 12 is provided with a wire hole, so that some wires can be stored inside the support rod 12, making the structure simpler.

[0043] Furthermore, the switch 14 can be mounted on the support rod 12, making the structure more compact.

[0044] Furthermore, the indicator light 18 can be set on the vernier scale 82 of the electronic digital display vernier caliper 8, which not only makes the structure compact, but also makes it easy to observe the status of the indicator light 18 during measurement.
