Description

Technical Field

[0001] The invention relates to the technical field of fine-tuning equipment, in particular to a reference plane fine-tuning equipment for calibrating a portable laser distance measuring equipment. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to accurately measure the distance to a target. When working, a pulsed laser rangefinder emits a beam or a series of short pulsed laser beams toward a target. The photoelectric element receives the laser beam reflected by the target, and a timer measures the time from the emission to the reception of the laser beam, thereby calculating the distance from the rangefinder to the target.

[0003] In the prior art, when using laser distance measuring equipment to measure distance, the triangulation distance measurement method is usually used to measure the distance of an object (refer to Figure 1 ), first of all, you need to place the laser distance measuring device on a stable platform surface, and then the laser emitted by the laser transmitter will be irradiated on the preset plane through the transmitter lens (L1 is the preset distance), the laser irradiation path is S1, and then the laser will be reflected by the object and will be reflected to the receiver lens position along the reflection angle a, the laser reflection path is S2, the receiver lens will focus the reflected light on the surface of the photosensitive element, and then irradiate the laser on the surface of the object to be measured. The laser irradiation path S1 changes, the reflection angle a and the reflection path S2 will change accordingly, and the position of the laser reflected on the surface of the photosensitive element will change accordingly. The laser distance measuring device will focus the laser on the photosensitive element. The distance of the object to be measured is calculated by changing the position of the laser distance measuring device; when measuring, the laser distance measuring device needs to be kept horizontal to ensure that the reflected laser can accurately pass through the receiver lens, but in the actual measurement process, it is usually difficult to place the laser distance measuring device horizontally by adjusting the placement position, so three adjustment legs are generally provided at the bottom of the laser distance measuring device to facilitate leveling of the laser distance measuring device, but when measuring distance, the adjustment legs need to be adjusted one by one, and the adjustment is cumbersome, and it is difficult to quickly level the laser distance measuring device. The laser distance measuring device cannot be adjusted to a horizontal level for distance measurement, which will cause the laser reflection path S2 to be unable to accurately reflect to the surface of the photosensitive element, affecting the measurement accuracy of the laser distance measuring device.

The weight block 24 is used to keep the adjustment rod 17 vertical when the support plate 1 is in a tilted state; The connecting mechanism includes a sliding groove 25, which is provided on the surface of the adjusting cylinder 5, and a sliding plate 26 is slidably connected in the sliding groove 25. The connecting plate 14 is hinged to the sliding plate 26, and two first friction rods 27 are fixedly connected to the surface of the sliding plate 26. Two second friction rods 28 are elastically slidably connected to the surface of the adjusting cylinder 5, and the two second friction rods 28 are respectively fitted with the two first friction rods 27. An L-shaped extension rod 29 is fixedly connected to the end of the second friction rod 28, and one side edge of the extension rod 29 is an inclined surface. A plurality of through openings 30 are provided on the surface of the support plate 1 corresponding to the positions of the plurality of friction blocks 12. An L-shaped pushing plate 31 is fixedly connected to the bottom of the friction block 12, and the pushing plate 31 is slidably connected to the bottom of the support plate 1 after extending to the bottom of the support plate 1. Two toggle blocks 32 are fixedly connected to the bottom surface of the pushing plate 31, and the toggle blocks 32 are close to the extension rod 29. The side is an inclined surface; When using the laser distance measuring device for distance measurement, it is first necessary to unfold the support legs 4, then place the support plate 1 in a predetermined position and try to keep the support plate 1 horizontal, the blocking block 13 is in a position to block the friction block 12, and then open the clamping plate 6 to place the laser distance measuring device body 2 on the surface of the support plate 1. The support plate 1 will squeeze the support legs 4 under the gravity of the laser distance measuring device body 2, and the support legs 4 will move toward the inside of the adjustment tube 5. The extension rod 29 on the surface of the adjustment tube 5 will act to push the rod 9 to move upward, and the push rod 9 will act to rotate the swing rod 7, and the swing rod 7 will act to clamp the clamping plate 6 to clamp the laser distance measuring device body 2. When the support plate 1 is in a tilted state, the laser distance measuring device body 2 will When the support plate 1 is deviated in the tilting direction, the laser ranging device body 2 will act on the clamping plate 6 in the tilting direction to move, and the movement of the clamping plate 6 will cause the swing rod 7 to rotate around the fixed plate 8, and the push rod 9 will move downward under the action of the swing rod 7 to push the extension plate 10 and the adjustment tube 5, while the support legs 4 and the adjustment tube 5 away from the tilting direction will be compressed under the action of the gravity of the laser ranging device body 2 and the support plate 1, and the clamping plate 6 on the side away from the tilting direction will move toward the side close to the laser ranging device body 2 to clamp the laser ranging device body 2, which is beneficial to use the offset of the laser ranging device body 2 to act on the adjustment tube 5 to move when the support plate 1 is in a tilted state, so that the lengths of multiple support legs 4 and the adjustment tube 5 can be adjusted to the support plate 1. The support plate 1 is in a horizontal state to prevent the support plate 1 from tilting, which will affect the measurement accuracy of the laser ranging equipment. When the adjustment cylinder 5 moves, the extension rod 29 and the second friction rod 28 will be blocked by the toggle block 32, and the sliding plate 26 can move in the sliding groove 25. Then, the blocking block 13 is toggled to release the blockage of the friction block 12, and the friction block 12 will move to the position of the friction plate 11. The friction block 12 and the friction plate 11 fit together to restrict the push rod 9, so that the push rod 9 remains stable. Then, by observing the two leveling tubes 3 to observe whether the bubble inside the leveling tube 3 is in the middle position, it is judged whether the support plate 1 is in a horizontal state. When the friction block 12 moves, the friction block 12 will drive the push plate 31 to move together in the through port 30, and the push plate 31 moves The movement will drive the toggle blocks 32 of the chain to move together, and the toggle block 32 will move to the side of the extension rod 29 to release the obstruction of the extension rod 29, and the second friction rod 28 will fit with the first friction rod 27, so that the sliding plate 26 can be connected to the adjustment cylinder 5. When the support plate 1 still cannot be in a horizontal state after the push rod 9 is restricted, the weight block 24 and the adjustment rod 17 will be in a vertical state under the action of gravity, and the fixing ring 18 will be in different positions of the multiple adjustment plates 15 under the action of the adjustment rod 17. The fixing ring 18 will be on the side of the adjustment plate 15 close to the tilt direction. The fixing ring 18 can automatically adjust the length of the left and right sides of the entire adjustment plate 15 with the fixing ring 18 as the dividing point according to the tilt degree of the support plate 1. Figure 2, the lengths of L3 and L4 will change with the inclination of the support plate 1, and then the adjusting ring 20 will be rotated, and the adjusting ring 20 will act on multiple arc plates 22 to move downward together through the adjusting thread 21, and the arc plate 22 will drive the end of the adjusting plate 15 to move downward together, and the adjusting plate 15 will rotate around the fixing ring 18, and the end of the adjusting plate 15 close to the adjusting cylinder 5 will drive the connecting plate 14 to move together, and the connecting plate 14 will drive the sliding plate 26 and the adjusting cylinder 5 to move upward together. The multiple adjusting plates 15 drive different adjusting cylinders 5 to move upward by different distances. The adjusting cylinder 5 on the side close to the inclination direction will be smaller when the adjusting plate 15 acts on the adjusting cylinder 5 because the fixing ring 18 is on the side close to the inclination direction, and the adjusting cylinder 5 on the side away from the inclination direction will be smaller when the adjusting plate 15 acts on the adjusting cylinder 5 to move. The moving distance of the cylinder 5 is large, which can reduce the inclination of the support plate 1 and gradually adjust the support plate 1 to the horizontal, which is conducive to quickly adjusting multiple support legs 4 and the adjustment cylinder 5, thereby realizing rapid leveling of the support plate 1, simplifying the operation during adjustment, and reducing the adjustment time. When the support plate 1 is in a tilted state, the weight block 24 and the adjustment rod 17 are in a vertical state, which will act on the adjustment plate 15 on both sides of the tilting direction to move horizontally. At this time, the end of the horizontally moving adjustment plate 15 will extend and retract according to the movement situation, and will rotate around the connecting plate 14 to a certain extent. The arc plate 22 and the telescopic block 23 will move along the adjusting thread 21 driven by the connecting plate 14, and the adjusting rod 17 and the weight block 24 can maintain a vertical state when the receiving plate is in a tilted state.

[0021] In the process of leveling the receiving plate, the arc plate 22 cannot remain stable when the adjusting ring 20 rotates, and is easy to rotate with the adjusting ring 20. As a further solution of the present invention, two telescopic blocks 23 are connected to the upper side of the arc plate 22, and the fixed end surfaces of the two telescopic blocks 23 are fixedly connected with a limiting rod 33. The push plate 31 extends away from the end of the friction block 12 to between the limiting rod 33 and the support plate 1. The thickness of the end of the push plate 31 is increased, and the push plate 31 is used to squeeze and limit the limiting rod 33. A clearance opening 34 is opened on the surface of the push rod 9, and the clearance opening 34 passes through the push plate 31, and the adjusting rod 17 passes through the clearance opening 34. When the friction block 12 is moved after the blocking block 13 is moved, the friction block 12 will drive the push plate 31 to move together, and the end of the push plate 31 will move between the limiting rod 33 and the connecting plate. The thickened end of the push plate 31 will squeeze the limiting rod 33, and the push plate 31 can limit the two telescopic blocks 23 by squeezing the limiting rod 33, so that the arc plate 22 can remain stable with the connecting plate during the adjustment process, ensuring the adjustment of the arc plate 22 by the rotation of the adjustment ring 20, thereby improving the accuracy of the adjustment.

[0022] When the support leg 4 and the adjustment rod 17 are adjusted, the support leg 4 cannot remain stable and is easy to shake. As a further solution of the present invention, a sliding block 35 is slidably connected to the bottom of the support plate 1, and two limit blocks 36 are fixedly connected to the ends of the sliding block 35. The two limit blocks 36 are located on the left and right sides of the support leg 4; During the adjustment of the support plate 1, it is necessary to first open the support leg 4 and then move the sliding block 35 so that the two limit blocks 36 are on the left and right sides of the support leg 4. The limit blocks 36 on the left and right sides of the support leg 4 can limit the support leg 4, which is beneficial for the support leg 4 to remain stable during the adjustment of the support plate 1 and ensure the accuracy of the adjustment.

[0023] In the process of adjusting the support plate 1, a gap is likely to appear between the support leg 4 and the blocking block 13, and the support leg 4 is likely to shake. As a further solution of the present invention, two limiting blocks 37 are fixedly connected to the surface of the sliding block 35, and the ends of the two limiting blocks 37 are inclined surfaces with different inclination directions. Two limiting grooves 38 are provided on the surface of the support leg 4 at positions corresponding to the two limiting blocks 37, and the insides of the two limiting grooves 38 are inclined surfaces identical to the ends of the two limiting blocks 37; During the adjustment of the support plate 1, when the sliding block 35 moves toward the side close to the support leg 4, the limiting block 37 will move into the limiting groove 38, and the inclined surfaces at the ends of the two limiting blocks 37 will work together with the inclined surfaces inside the two limiting grooves 38 to support the support leg 4, so that the support leg 4 can remain stable during the adjustment process, thereby ensuring the accuracy of the adjustment of the adjustment cylinder 5.
