Description

Technical Field

[0001] This invention relates to the field of calibration device technology, and in particular to a calibration device for a foundation settlement detection system. Background Technology

[0002] The existing foundation settlement detection system calibration device is described in patent application number CN2015102050813, which includes a calibration device body and a track inspection vehicle. The track inspection vehicle includes a mobile trolley, a marker and a line array camera are set on one side of the mobile trolley, and the calibration device body includes a tripod, a guide rail mounted on the tripod, a calibration ruler that can move along the guide rail, and a laser rangefinder set on the upper end of the calibration ruler.

[0003] Existing ground settlement detection system calibration devices require manual adjustment of the tripod using a level and fine-tuning mechanism to ensure the laser rangefinder output is horizontally directed onto the markings on the track inspection vehicle. This process of leveling the laser rangefinder output is inefficient in existing calibration devices. Summary of the Invention

[0004] To address the inefficiency of existing calibration devices for foundation settlement detection systems in adjusting the output direction of laser rangefinders to a horizontal position, this invention proposes a calibration device for foundation settlement detection systems that can quickly adjust the output direction of laser rangefinders to a horizontal position.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A calibration device for a foundation settlement detection system includes a track inspection vehicle and a calibration device body. The calibration device body includes an upper base plate, a track fixedly connected to the upper side of the upper base plate, a sliding seat movable along the track, a calibration ruler fixedly connected to the upper side of the sliding seat, and a laser rangefinder fixedly connected to the upper end of the calibration ruler. When the upper base plate is horizontal, the output direction of the laser rangefinder is horizontal. The calibration device body also includes a bracket, with a support column and a ball joint fixedly connected to the bracket. A ball joint is rotatably connected inside the ball joint, and a limit component is fixedly connected to the upper side of the ball joint. A locking mechanism is provided on the bracket. The ball joint has a sliding groove penetrating both the upper and lower sides of the ball joint, through which a guide rod passes. The guide rod and the sliding groove are slidably connected. A lower base plate is fixedly connected to the upper end of the rod, and a gravity ball is fixedly connected to the lower end of the guide rod. A support plate is set below the gravity ball, and the bracket is equipped with a drive mechanism for driving the support plate to move up and down. The calibration device body includes a leveling state and a working state. When the calibration device body is in the leveling state, the support column supports the upper base plate, the upper base plate and the lower base plate are separated and abut against the upper side of the limiting member, the locking mechanism is separated from the ball head, so that the ball head can rotate freely relative to the ball head seat, the gravity ball and the support plate are separated, and the lower base plate is horizontal under the gravity of the gravity ball. When the calibration device body is in the working state, the lower base plate is horizontal, the locking mechanism locks the ball head in the ball head seat, the support plate supports the gravity ball, and the upper base plate is attached to the upper side of the lower base plate.

[0007] In this application, after the pallet descends, the lower base plate automatically levels under the action of the gravity ball; after the locking mechanism locks the ball head, the lower base plate remains level; finally, the pallet rises, and the upper base plate is raised through the gravity ball, guide rod, and lower base plate. Simultaneously, as the upper base plate levels, the output direction of the laser rangefinder automatically levels; the entire leveling process is very convenient. Furthermore, during the leveling of the lower base plate, the support column separates the upper and lower base plates, allowing the sliding seat to complete the leveling of the lower base plate regardless of its position on the track.

[0008] Furthermore, a positioning shaft is fixedly connected to the upper side of the lower base plate, and a positioning hole is provided on the upper base plate. The inner diameter of the positioning hole is the same as the outer diameter of the positioning shaft. When the calibration device body is in working condition, the positioning shaft passes through the positioning hole and is rotatably connected to the positioning hole. A magnetic seat is provided on the upper base plate that can attract the lower base plate to lock the upper base plate on the lower base plate.

[0009] With the above settings, when the upper base plate is attached to the lower base plate, the upper base plate can rotate around the axis of the positioning shaft, which makes it convenient for the laser rangefinder to align with the rail inspection vehicle. When the magnetic seat attracts the lower base plate, the upper base plate is locked onto the lower base plate.

[0010] Furthermore, the drive mechanism includes a first screw extending vertically and a motor for driving the first screw to rotate, the first screw passing through the support plate and being threadedly connected to the support plate.

[0011] Furthermore, the bracket includes a mounting plate and several swing feet fixedly connected to the lower side of the mounting plate, support columns fixedly connected to the upper side of the mounting plate, ball joints fixedly connected to the middle of the mounting plate, and support columns arranged around the ball joints.

[0012] Furthermore, the mounting plate is provided with a mounting groove, and the locking mechanism includes a top cylinder provided in the mounting groove. The output shaft of the top cylinder faces the ball head and is provided with a friction plate. When the locking mechanism locks the ball head in the ball head seat, the friction plate presses against the ball head.

[0013] Furthermore, a housing is provided above the upper base plate. The housing is fixedly connected to the upper base plate via a connecting rod. A track is fixedly connected inside the housing. The housing is rotatably connected to a second screw parallel to the track. The second screw is threadedly connected to a sliding seat. A handle is fixedly connected to one end of the second screw.

[0014] With the above setup, the calibration work is completed by rotating the handle to move the sliding seat along the track.

[0015] Furthermore, the track inspection vehicle includes a mobile trolley, with camera brackets fixedly connected to both the left and right sides of the mobile trolley. Linear array cameras for photographing the calibration ruler are installed at both the upper and lower ends of the camera brackets. A mark is set in the middle of the camera bracket. When the calibration device body is in working condition, the drive mechanism drives the pallet to move up and down to adjust the height of the laser rangefinder so that the output height of the laser rangefinder is consistent with the calibration height.

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] See Figures 1 to 4A calibration device for a foundation settlement detection system includes a track inspection vehicle 11 and a calibration device body 12. The calibration device body 12 includes an upper base plate 121, a track 122 fixedly connected to the upper side of the upper base plate 121, a sliding seat 123 movable back and forth along the track 122, a calibration ruler 124 fixedly connected to the upper side of the sliding seat 123, and a laser rangefinder 125 fixedly connected to the upper end of the calibration ruler 124. When the upper base plate 121 is horizontal, the output direction of the laser rangefinder 125 is horizontal. The calibration device body 12 also includes a support... Frame 126, bracket 126 is fixedly connected to support column 1261 and ball head 1263 seat 1262, ball head 1263 is rotatably connected inside ball head 1263 seat 1262, limit member 1264 is fixedly connected to the upper side of ball head 1263, bracket 126 is provided with locking mechanism 1265, ball head 1263 is provided with sliding groove 1266 through the upper and lower sides of ball head 1263, guide rod 1267 passes through sliding groove 1266, guide rod 1267 and sliding groove 1266 are slidably connected, upper end of guide rod 1267 A lower base plate 12671 is fixedly connected, and a gravity ball 12672 is fixedly connected to the lower end of the guide rod 1267. A support plate 13 is provided below the gravity ball 12672. The bracket 126 is provided with a drive mechanism 14 for driving the support plate 13 to move up and down. The calibration device body 12 includes a leveling state and a working state. When the calibration device body 12 is in the leveling state, the support column 1261 supports the upper base plate 121. The upper base plate 121 and the lower base plate 12671 are disengaged and abut against the upper side of the limiting member 1264. The locking mechanism 12... 65 and ball head 1263 are disengaged so that ball head 1263 can rotate freely relative to ball head 1263 seat 1262. Gravity ball 12672 and support plate 13 are disengaged. The lower base plate 12671 is horizontal under the gravity of gravity ball 12672. When the calibration device body 12 is in working state, the lower base plate 12671 is horizontal. The locking mechanism 1265 locks ball head 1263 in ball head 1263 seat 1262. Support plate 13 supports gravity ball 12672. Upper base plate 121 is attached to the upper side of lower base plate 12671.

[0022] In this application, after the support plate 13 descends, the lower base plate 12671 automatically levels under the action of the gravity ball 12672; after the locking mechanism 1265 locks the ball head 1263, the lower base plate 12671 remains level; finally, the support plate 13 rises, and the upper base plate 121 is raised through the gravity ball 12672, guide rod 1267, and lower base plate 12671. While the upper base plate 121 is level, the output direction of the laser rangefinder 125 automatically levels; the entire leveling process is very convenient. In addition, during the leveling process of the lower base plate 12671, the support column 1261 separates the upper base plate 121 and the lower base plate 12671, and the sliding seat 123 can complete the leveling of the lower base plate 12671 regardless of its position on the track 122.

[0023] For the specific calibration process and principle of this application, please refer to the patent with application number CN2015102050813. This section mainly describes the process of leveling the output direction of the laser rangefinder 125. The specific process is as follows: [See...] Figure 4 Under the action of the drive mechanism 14, the pallet 13 moves downward. The gravity ball 12672, guide rod 1267, and lower base plate 12671 move downward along the slide groove 1266 under the action of gravity. After the support column 1261 supports the upper base plate 121, the lower base plate 12671 continues to move downward and separates from the upper base plate 121. After the lower base plate 12671 abuts against the limiting member 1264, the lower base plate 12671, guide rod 1267, and gravity ball 12672 stop moving downward. As the support plate 13 continues to move downwards and separates from the gravity ball 12672, the ball head 1263 can rotate freely within the ball head 1263 seat 1262. Under the influence of the gravity ball 12672, the guide rod 1267 automatically becomes vertical, and the lower base plate 12671 automatically becomes horizontal. Then, the locking mechanism 1265 locks the ball head 1263 within the ball head 1263 seat 1262, thereby preventing the ball head 1263 from continuing to rotate and locking the lower base plate 12671 in a horizontal state. (See also...) Figure 4 Then, under the action of the drive mechanism 14, the support plate 13 moves upward, lifting the gravity ball 12672, the guide rod 1267, and the lower base plate 12671 upward. Finally, the lower base plate 12671 lifts the upper base plate 121. When the upper base plate 121 is attached to the lower base plate 12671, the upper base plate 121 is also horizontal, and the output direction of the laser rangefinder 125 is automatically horizontal. See [link / reference]. Figure 2 .

[0024] As one implementation, a positioning shaft 12673 is fixedly connected to the upper side of the lower base plate 12671, and a positioning hole 1211 is provided on the upper base plate 121. The inner diameter of the positioning hole 1211 is the same as the outer diameter of the positioning shaft 12673. When the calibration device body 12 is in working state, the positioning shaft 12673 passes through the positioning hole 1211 and is rotatably connected to the positioning hole 1211. A magnetic seat 1212 is provided on the upper base plate 121 to attract the lower base plate 12671 and lock the upper base plate 121 onto the lower base plate 12671.

[0025] With the above settings, when the upper base plate 121 is attached to the lower base plate 12671, the upper base plate 121 can rotate around the axis of the positioning shaft 12673, which facilitates the laser rangefinder 125 to be aligned with the track inspection vehicle 11. When the magnetic seat 1212 adsorbs the lower base plate 12671, the upper base plate 121 is locked onto the lower base plate 12671.

[0026] In one implementation, the drive mechanism 14 includes a first screw 141 extending vertically and a motor 142 for driving the first screw 141 to rotate. The first screw 141 passes through the support plate 13 and is threadedly connected to the support plate 13.

[0027] When the motor 142 drives the first screw 141 to rotate, the first screw 141 and the support plate 13 rotate relative to each other, and the support plate 13 moves up or down along the first screw 141.

[0028] In one implementation, the bracket 126 includes a mounting plate 1268 and several swing feet 1269 fixedly connected to the lower side of the mounting plate 1268. The support column 1261 is fixedly connected to the upper side of the mounting plate 1268, and the ball head 1263 seat 1262 is fixedly connected to the middle part of the mounting plate 1268. The support column 1261 is arranged around the ball head 1263 seat 1262.

[0029] As one implementation, the mounting plate 1268 is provided with a mounting groove 12681, and the locking mechanism 1265 includes a top cylinder 12651 provided in the mounting groove 12681. The output shaft of the top cylinder 12651 faces the ball head 1263 and is provided with a friction plate 12652. When the locking mechanism 1265 locks the ball head 1263 in the ball head 1263 seat 1262, the friction plate 12652 is pressed against the ball head 1263.

[0030] When the top cylinder 12651 presses the friction plate 12652 onto the ball head 1263, the ball head 1263 is locked inside the ball head 1263 seat 1262. When the top cylinder 12651 separates the friction plate 12652 and the ball head 1263, the ball head 1263 can rotate freely inside the ball head 1263 seat 1262.

[0031] As one implementation, a housing 15 is provided above the upper base plate 121. The housing 15 is fixedly connected to the upper base plate 121 via a connecting rod 16. A track 122 is fixedly connected inside the housing 15. The housing 15 is rotatably connected to a second screw 151 parallel to the track 122. The second screw 151 is threadedly connected to a sliding seat 123. A handle 152 is fixedly connected to one end of the second screw 151.

[0032] With the above settings, the calibration work is completed by rotating the handle 152 to make the sliding seat 123 move along the track 122.

[0033] When the handle 152 drives the second screw 151 to rotate, the second screw 151 and the sliding seat 123 rotate relative to each other, and the sliding seat 123 moves forward or backward along the track 122.

[0034] As one implementation, the track inspection vehicle 11 includes a mobile trolley 111, with camera brackets 112 fixedly connected to both the left and right sides of the mobile trolley 111. Linear array cameras 113 for photographing the calibration ruler 124 are set at both the upper and lower ends of the camera brackets 112. A mark is set in the middle of the camera brackets 112. When the calibration device body 12 is in working condition, the drive mechanism 14 drives the support plate 13 to move up and down to adjust the height of the laser rangefinder 125 so that the output height of the laser rangefinder 125 is consistent with the calibration height.

[0035] Among them, the camera bracket 112 is used to support the line scan camera 113, and the line scan camera 113 is used to photograph the calibration ruler 124 to complete the calibration operation.

[0036] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
