Description

Technical Field

[0001] The utility model belongs to the field of ladle erosion early warning, and specifically relates to a protection and angle adjustment device for a ladle lining thickness measuring scanner. Background Art

[0002] Ladle is a commonly used high-temperature smelting container. During use, the refractory material of the ladle lining will be penetrated and eroded when in contact with molten steel and slag, and will also be damaged by thermal stress caused by temperature fluctuations. Although the remaining thickness of the refractory material of the ladle lining is generally clearly stipulated on site, it still mainly relies on the visual observation of on-site operators for empirical judgment, which has problems such as large judgment errors, poor real-time performance, and safety hazards.

[0003] In the prior art, there is a method of using a laser radar scanner to scan, measure and calculate the residual thickness of the ladle lining, but it is difficult to be effectively promoted and applied in practical applications. The main difficulty is that the temperature of the airflow directly above the ladle often reaches 400~800℃, and the airflow directly above contains a large amount of metal dust, while the working environment temperature suitable for the laser radar scanner generally does not exceed 50℃. The high temperature environment will cause the performance of some components of the laser radar system to deteriorate, such as deformation of optical components and aging of electronic components. High dust will also cause signal attenuation and noise increase in the scanner, resulting in a decrease in signal-to-noise ratio and detection performance. The authorized CN 210689527 discloses an online ladle residual thickness detection device equipped with a mobile trolley. Although the height of the laser radar scanner can be adjusted, it can only scan the upper edge position area of ​​the ladle outside the upper edge of the ladle, but cannot scan the entire ladle lining. Authorized CN 110726370 discloses a mobile device for a laser thickness scanner for the ladle lining, which solves the problem that the laser radar scanner can be pushed to the top of the ladle for scanning, but does not mention how to adjust the scanner angle to scan the entire ladle lining. In addition, although the laser radar scanner is moved away from the top of the ladle when not in use, it does not consider the need to protect the laser radar scanner when not in use, that is, when the water cooling and air cooling are stopped. Summary of the invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a protection and angle adjustment device for a ladle lining thickness scanner, which enables the laser radar scanner to overcome the high temperature and high dust environment directly above the ladle, and can automatically adjust the angle through program settings to scan the entire area of ​​the ladle lining, and is equipped with an integral protective cover when not in use, so as to more effectively extend the service life of the laser radar scanner. The technical solution is as follows:

[0005] A protection and angle adjustment device for a ladle lining thickness measuring scanner comprises a scanner protection shell, an angle adjustment mechanism, and a fixing and protection mechanism.

[0006] The scanner protection shell includes a connecting plate, a water cooling mechanism and an air sweeping mechanism, and is internally bolted to fix and install a laser radar scanner for scanning the lining of the ladle, thereby fixing, cooling, removing dust and protecting the laser radar scanner; the connecting plate is welded to the water cooling mechanism; the connecting plate is welded to the air sweeping mechanism; the water cooling mechanism includes a water inlet, a water outlet and a water cooling channel; the air sweeping mechanism includes an air inlet and an air sealing pipe.

[0007] Furthermore, the outer partition of the air-sealed duct is inclined inwardly, leaving a gap with the inner partition and is slightly longer than the inner partition. Wind blows out from the gap, which enables the gas to be blown more concentratedly to the laser radar scanner, thereby achieving a better dust removal effect.

[0008] The angle adjustment mechanism comprises a support base connecting plate, a fixing frame, and a radar connecting plate. The bottom of the radar connecting plate is bolted to fix the scanner protection shell.

[0009] Furthermore, the angle adjustment mechanism is also provided with a first synchronous wheel, a second synchronous wheel, a synchronous belt, a pulley cover, and a motor. The motor is fixedly connected to the first synchronous wheel via an axis, and the second synchronous wheel is fixedly connected to the connecting plate of the scanner protective shell via an axis.

[0010] The working principle of the angle adjustment mechanism is as follows: when the motor is working, it drives the first synchronous wheel to rotate, and then drives the second synchronous wheel to rotate through the synchronous belt, and then drives the scanner protection shell to rotate, thereby realizing the angle adjustment of the laser radar scanner.

[0011] The fixing and protection mechanism comprises a support seat, a protection cover mechanism, and a hydraulic push rod mechanism. The bottom of the support seat is bolted to fix the angle adjustment mechanism.

[0012] Furthermore, the shield mechanism includes a shield body, shield supports on left and right sides, and a shield shaft. The shield body is fixedly connected to the shield shaft and is axially rotatable with the support seat via an axis.

[0013] Furthermore, the hydraulic push rod mechanism includes a hydraulic cavity, a hydraulic push rod, and a push rod support. The front end of the hydraulic push rod is connected to the protective cover shaft through an axis and can rotate axially.

[0014] The working principle of the fixing and protection mechanism is as follows: when the hydraulic push rod is pushed forward, it drives the protection cover shaft to move forward, thereby driving the protection cover body to rotate backward and open, so that the scanner protection shell is directly above the ladle, so that the laser radar scanner can scan the ladle; when the scanning is completed, the hydraulic push rod returns to its position backward, thereby driving the protection cover body to return forward to directly below the scanner protection shell, blocking the scanner protection shell and preventing the ladle from radiating heat to the scanner protection shell and the laser radar scanner.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] Firstly, the design of the fixing and protection mechanism in the utility model allows the laser radar scanner to be permanently set at a fixed position just above the ladle mouth without moving, thus saving testing time and realizing real-time online detection.

[0017] Secondly, the air-sealed pipe structure design in the air sweeping mechanism of the utility model can make the gas blow more concentratedly to the laser radar scanner, thereby achieving a better dust removal effect.

[0018] Thirdly, the angle adjustment mechanism in the utility model can realize accurate control of the scanning angle, thereby realizing full-area scanning of the ladle without blind spots.

[0019] Fourthly, all operations on the device in the utility model are carried out in a remote control room, which improves the working environment of the staff and improves safety. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The technical solution embodiment of the utility model is as follows Figure 1-4 As shown, a protection and angle adjustment device for a ladle lining thickness measuring scanner comprises: a scanner protection shell 1, an angle adjustment mechanism 2, and a fixing and protection mechanism 3.

[0028] The scanner protection shell 1 includes a connecting plate 11, a water cooling mechanism 12 and an air sweeping mechanism 13, and is internally bolted to fix and install a laser radar scanner for scanning the lining of the ladle, thereby fixing, cooling, removing dust and protecting the laser radar scanner; the connecting plate 11 is welded to the water cooling mechanism 12; the connecting plate 11 is welded to the air sweeping mechanism 13; the water cooling mechanism 12 includes a water inlet 121, a water outlet 122 and a water cooling channel 123; the air sweeping mechanism 13 includes an air inlet 131 and an air sealing pipe 132.

[0029] Furthermore, the outer partition 1321 of the air-sealed duct 132 is inclined inwardly, leaving a gap between the outer partition 1321 and the inner partition 1322 and being slightly longer than the inner partition 1322. Wind blows out from the gap, which enables the gas to be blown more concentratedly to the laser radar scanner, thereby achieving a better dust removal effect.

[0030] The angle adjustment mechanism 2 includes a support base connecting plate 21, a fixing frame 22, and a radar connecting plate 23. The bottom of the radar connecting plate 23 is bolted to fix the scanner protection housing 1.

[0031] Furthermore, the angle adjustment mechanism 2 is also provided with a first synchronous wheel 24, a second synchronous wheel 25, a synchronous belt 26, a pulley cover 27, and a motor 28. The motor 28 is fixedly connected to the first synchronous wheel 24 via an axis, and the second synchronous wheel 25 is fixedly connected to the connecting plate 11 of the scanner protective shell 1 via an axis.

[0032] The fixing and protection mechanism 3 comprises a support seat 31 , a protection cover mechanism 32 , and a hydraulic push rod mechanism 33 . The bottom of the support seat 31 is bolted to fix the angle adjustment mechanism 2 .

[0033] Furthermore, the shield mechanism 32 includes a shield body 321, shield supports 322 on left and right sides, and a shield shaft 323. The shield body 321 is fixedly connected to the shield shaft 323 and is axially rotatable with the support seat 31 via an axis connection.

[0034] Furthermore, the hydraulic push rod mechanism 33 includes a hydraulic cavity 331, a hydraulic push rod 332, and a push rod support 333. The front end of the hydraulic push rod 332 is axially connected to the protective cover shaft 323 through an axis and can rotate axially.

[0036] When the ladle to be tested moves to the ladle area to be tested, the hydraulic push rod 332 pushes forward, driving the protective cover shaft 323 to move forward, thereby driving the protective cover body 321 to rotate backward and open, so that the scanner protection shell 1 is directly above the ladle, and the laser radar scanner starts to scan the ladle. During the scanning process, when it is necessary to adjust the scanning angle, the motor 28 starts to start, driving the first synchronous wheel 24 to rotate, and then driving the second synchronous wheel 25 to rotate through the synchronous belt 26, and then driving the scanner protection shell 1 to rotate, thereby achieving the angle adjustment of the laser radar scanner. When the scanning is completed, the hydraulic push rod 332 returns to its position backward, thereby driving the protective cover body 321 to return forward to the position directly below the scanner protection shell 1, shielding the scanner protection shell 1, and preventing the ladle from radiating heat to the scanner protection shell 1 and the laser radar scanner.

[0037] After adopting the above technical solution, the beneficial effects of the utility model are:

[0038] Firstly, compared with the mobile testing equipment in the prior art, the device of the utility model saves the testing time and realizes the real-time online detection.
