[0002] After the carbon block is roasted, the wall deformation of the roasting furnace material box needs to be measured. However, due to the design defects of the laser head integrated structure, the laser head shakes during data collection in the prior art equipment, thus affecting the accuracy of data collection. At the same time, due to the design defects, there is no solution to keep the laser head and other measuring instruments stable. Once the laser head shakes, it will not only affect the accuracy of data collection, but also affect the service life of the equipment transmission mechanism.

[0073] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0074] See also Figures 1 to 15 As shown;

[0075] This embodiment discloses a laser measurement device for deformation of a furnace flue wall, the measurement device comprising:

[0076] Carrying platform 1;

[0077] A first 86 stepper motor reducer 201 and a second 86 stepper motor reducer 202 integrated at both ends of the carrying platform 1 in the length direction; and

[0078] A measuring device upper plate 301 connected to the first 86 stepping motor reducer 201 and the second 86 stepping motor reducer 202;

[0079] The upper plate 301 of the measuring device is slidably connected to the support rail 101 of the carrying platform 1 through the upper plate slider 303, and the first 86 stepper motor reducer 201 and the second 86 stepper motor reducer 202 are connected to the upper plate 301 of the measuring device through a transmission mechanism to drive the upper plate 301 of the measuring device to move horizontally along the length direction of the carrying platform 1;

[0080] The measuring device also includes:

[0081] The measuring device lower plate 302 is located below the measuring device upper plate 301 and is integrated with a measuring and data acquisition component 5;

[0082] Two groups of four-bar mechanisms 6 are arranged between the upper plate 301 of the measuring device and the lower plate 302 of the measuring device, and a third 86 stepping motor reducer 203 is integrated on the upper plate 301 of the measuring device, and a steel wire rope 209 is wound around the output end of the third 86 stepping motor reducer 203, and the steel wire rope 209 passes around the take-up wheel 207 on the upper plate 301 of the measuring device and passes through the upper plate 301 of the measuring device to be connected with the lower plate 302 of the measuring device;

[0083] The third 86 stepping motor reducer 203 lowers the measuring device lower plate 302 through the steel wire rope 209 and the deadweight of the measuring device lower plate 302;

[0084] When the third 86 stepper motor reducer 203 drives the measuring device lower plate 302 to move downward in the vertical direction, the carbon fiber tube assembly 4 between the measuring device upper plate 301 and the measuring device lower plate 302 is deformed along with the downward movement of the measuring device lower plate 302 to maintain the position of the measuring device lower plate 302.

[0085] Specifically, the present embodiment discloses a laser measuring device suitable for monitoring the deformation of the flue wall of a roasting furnace; the device is mainly composed of a bearing platform 1, on which a movable upper plate 301 of the measuring device and a lower plate 302 of the measuring device that is movably connected to the upper plate 301 of the measuring device and can be moved in the vertical direction to adjust the height are arranged. Among them, in order to realize the horizontal movement of the upper plate 301 of the measuring device, a first 86 stepper motor reducer 201 and a second 86 stepper motor reducer 202 are arranged at both ends of the bearing platform 1. Through the reasonable design of the transmission structure, the first 86 stepper motor reducer 201 and the second 86 stepper motor reducer 202 can be used to drive the upper plate 301 of the measuring device to move along the support guide rail 101 of the bearing platform 1 to adjust the horizontal position. Two sets of four-bar mechanisms 6 are arranged between the upper plate 301 of the measuring device and the lower plate 302 of the measuring device in this embodiment, which can cooperate with the third 86 stepper motor reducer 203 and the steel wire cylinder structure to act on the lower plate 302 of the measuring device to realize the lowering of the lower plate 302 of the measuring device. In addition, the carbon fiber tube structure designed in this embodiment assists the lowering of the lower plate 302 of the measuring device, and can prevent the lower plate 302 of the measuring device from shaking when it is lowered through the deformation of the parallelogram-shaped carbon fiber tube structure, thereby improving the accuracy of the measurement data of the laser measuring device.

[0086] Preferably, the first 86 stepper motor reducer 201 and the second 86 stepper motor reducer 202 of this embodiment are both integrated on the carrying platform 1 through the stepper motor support plate 204;

[0087] The lower part of the stepper motor support plate 204 is provided with a second-mode gear 206 which is respectively driven by the 86 stepper motor reducer on the corresponding side, and the 86 stepper motor reducer is meshed with the second-mode rack of the lower mechanism below the mechanism through the second-mode gear 206.

[0088] The carrying platform 1 of the present embodiment is made of aluminum alloy profiles, and in order to integrate the first 86 stepper motor reducer 201 and the second 86 stepper motor reducer 202, a stepper motor support plate 204 is arranged at the corresponding position of the carrying platform 1. In addition, the output ends of the first 86 stepper motor reducer 201 and the second 86 stepper motor reducer 202 of the present embodiment are connected with a second-mode gear 206, which is engaged with the second-mode rack (not shown, not as the key protection content of this application) of the lower frame of the overall carrying platform 1, so that the two 86 stepper motors can drive the device to complete horizontal linear reciprocating motion on the carrying platform 1.

[0089] The upper plate 301 of the measuring device in this embodiment is provided with an upper plate slider 303 , which is slidably matched with the support rail 101 of the carrying platform 1 to ensure that the upper plate 301 of the measuring device has redundancy in the horizontal direction.

[0090] The measuring device upper plate 301 of this embodiment is integrated with the third 86 stepper motor reducer 203, and the wire rope 209 on it passes around the take-up wheel 207 and passes through the circular hole in the center of the measuring device upper plate 301 and is connected to the measuring device lower plate 302. The take-up wheel 207 of this embodiment is integrated with the measuring device upper plate 301 through the take-up wheel support seat 208.

[0091] Preferably, this embodiment further defines the linkage structure between the upper plate 301 of the measuring device and the lower plate 302 of the measuring device, that is, the specific structure of the two sets of four-bar mechanisms 6 mentioned above, specifically:

[0092] The four corners of the lower part of the upper plate 301 of the measuring device of this embodiment are respectively provided with an upper plate first fixed joint 601, an upper plate second fixed joint 602, an upper plate third fixed joint 603 and an upper plate fourth fixed joint 604;

[0093] The first upper plate fixed joint 601, the second upper plate fixed joint 602, the third upper plate fixed joint 603 and the fourth upper plate fixed joint 604 are respectively hinged with the first upper plate movable joint 605, the second upper plate movable joint 606, the third upper plate movable joint 607 and the fourth upper plate movable joint 608;

[0094] Each set of fixed joints and movable joints constitutes a set of joint components, and a synchronization shaft is installed between the two sets of joint components located on the same side of the upper plate of the measuring device, and the two synchronization shafts are respectively a first synchronization shaft 609 and a second synchronization shaft 610;

[0095] An upper platform rocker arm assembly is arranged between the two synchronous shafts;

[0096] The upper platform rocker arm assembly includes:

[0097] A first upper platform rocker arm 611 connected to the first synchronization shaft 609 and rotating along with the first synchronization shaft 609; and

[0098] A second upper platform rocker arm 612 connected to the second synchronization shaft 610 and rotating along with the second synchronization shaft 610;

[0099] An upper platform connecting rod 613 is connected between the first upper platform rocker arm 611 and the second upper platform rocker arm 612 .

[0100] Secondly, the four corners of the upper portion of the lower plate 302 of the measuring device of this embodiment are respectively provided with a lower plate first fixed joint 614, a lower plate second fixed joint 615, a lower plate third fixed joint 616 and a lower plate fourth fixed joint 617;

[0101] The first fixed joint 614, the second fixed joint 615, the third fixed joint 616 and the fourth fixed joint 617 of the lower plate are respectively hinged with the first movable joint 618, the second movable joint 619, the third movable joint 620 and the fourth movable joint 621 of the lower plate;

[0102] Each set of fixed joints and movable joints constitutes a set of joint components, and a synchronization shaft is installed between the two sets of joint components located on the same side of the lower plate 302 of the measuring device, and the two synchronization shafts are respectively the third synchronization shaft 622 and the fourth synchronization shaft 623;

[0103] A lower platform rocker arm assembly is arranged between the two synchronous shafts;

[0104] The lower platform rocker arm assembly includes:

[0105] A first lower platform rocker arm 624 connected to the third synchronization shaft 622 and rotating along with the third synchronization shaft 622; and

[0106] A second lower platform rocker arm 625 connected to the fourth synchronization shaft 623 and rotating along with the fourth synchronization shaft 623;

[0107] A lower platform connecting rod 626 is connected between the first lower platform rocker arm 624 and the second lower platform rocker arm 625 .

[0108] Preferably, the ends of the first upper plate movable joint 605, the second upper plate movable joint 606, the third upper plate movable joint 607 and the fourth upper plate movable joint 608 of the present embodiment are respectively connected with the first carbon fiber tube 401, the second carbon fiber tube 402, the third carbon fiber tube 403 and the fourth carbon fiber tube 404;

[0109] The ends of the first carbon fiber tube 401, the second carbon fiber tube 402, the third carbon fiber tube 403 and the fourth carbon fiber tube 404 are respectively connected to the first middle single ear joint of the measuring material box rod, the second middle single ear joint of the measuring material box rod, the third middle single ear joint of the measuring material box rod and the fourth middle single ear joint of the measuring material box rod;

[0110] The ends of the first movable joint 618, the second movable joint 619, the third movable joint 620 and the fourth movable joint 621 of the lower plate are respectively connected with the fifth carbon fiber tube 405, the sixth carbon fiber tube 406, the seventh carbon fiber tube 407 and the eighth carbon fiber tube 408;

[0111] The ends of the fifth carbon fiber tube 405, the sixth carbon fiber tube 406, the seventh carbon fiber tube 407 and the eighth carbon fiber tube 408 are respectively connected to the fifth single ear joint of the measuring material box rod, the sixth single ear joint of the measuring material box rod, the seventh single ear joint of the measuring material box rod and the eighth single ear joint of the measuring material box rod.

[0112] The eight carbon fiber tubes are spatially distributed in the form of two parallelogram arrangements;

[0113] When the third 86 stepper motor reducer 203 drives the measuring device lower plate 302 to move downward in the vertical direction, the parallelogram structure is deformed along with the downward movement of the measuring device lower plate 302 to maintain the position of the measuring device lower plate 302.

[0114] The maximum angle between the two carbon fiber tubes in the middle is 168°, and the minimum angle between the two carbon fiber tubes in the middle is 8°;

[0115] The carbon fiber tube has a length of 3 m, a diameter of 20 mm, and a wall thickness of 2 mm.

[0116] The synchronous shaft of the measuring device of this embodiment passes through the holes of the joint assemblies on both sides. At the same time, the rocker arm is installed at the corresponding joints on the synchronous shaft and then connected with a connecting rod. In this way, the synchronous shaft can be driven to rotate while the movable joint rotates, and the rotation of the synchronous shaft will also drive the connecting rod rocker arm mechanism to move, ultimately achieving the design purpose of lowering or raising the laser radar 501.

[0117] This embodiment uses eight carbon fiber tubes to form two sets of parallelogram distribution structures in space, which can ensure the smooth lowering process of the laser radar 501 and ensure the accuracy of the data measured by the laser radar 501. The device uses three sets of 86 stepper motors with encoders, in which the third 86 stepper motor reducer is connected to the wire roller to enable the measuring device to achieve closed-loop control, thereby increasing the accuracy of the measured data.

[0118] In addition, in order to avoid the middle fiber tube being at the position of 0° and 180°, this embodiment aims to prevent the dead point from affecting the movement performance of the mechanism. Therefore, in the initial position, the angle between the two middle carbon fiber tubes is 8°. This angle is used to prevent the lower platform connecting rod from interfering with the synchronization axis of the upper platform. In the extreme position, the angle between the two middle carbon fiber tubes is 168°. At this time, the laser radar 501 is 5.95m away from the ground. This angle is used to prevent the angle between the upper and lower carbon fiber tubes from reaching the dead point of 180°, thereby ensuring the continuity and stability of the movement of the mechanism.

[0119] Preferably, the upper part of the lower plate 302 of the measuring device of this embodiment is symmetrically provided with video cameras 506, which are respectively a first video camera and a second video camera;

[0120] The first video camera and the second video camera are integrated into the lower plate 302 of the measuring device through the first video equipment supporting seat and the second video equipment supporting seat respectively.

[0121] Among them, a laser radar bearing plate 503 is arranged at the lower part of the middle part of the lower plate 302 of the measuring device of this embodiment through a symmetrical connecting plate 502; a laser radar 501 is installed on the laser radar bearing plate 503, and a laser radar protective cover 504 is arranged on the outside of the laser radar 501.

[0122] The laser radar 501 of this embodiment is installed at the bottom of the laser measuring device, and there is no interference or shielding from the laser measuring device itself. Therefore, the accuracy of the data measured by the radar is also guaranteed.

[0123] In the above technical solution, the utility model provides a roasting furnace flue wall deformation laser measurement device, which has the following beneficial effects:

[0124] The device of the utility model adopts eight carbon fiber tubes to form two sets of parallelogram structures in space. The structure can assist the laser platform to achieve stable operation during the process below, and ensure that the laser radar measurement data is accurate.

[0125] The device of the utility model adopts carbon fiber tubes to achieve the purpose of weight reduction. Through the design of three sets of 86 stepper motors with encoders, one set of which is connected to the wire roller, the device realizes closed-loop control and increases the accuracy of measurement data.
