Description

Technical Field

[0001] The present invention relates to the technical field of length measurement, and in particular to a device for detecting the length of a three-dimensional shelf beam. Background Art

[0002] Three-dimensional racking is a high-density, multi-level storage equipment that improves the storage capacity and space utilization of the warehouse by making full use of the vertical space. It is usually composed of columns, beams, shelves, pallet supports and other components. Among them, the beam is one of the main load-bearing components of the three-dimensional racking. Its length together with other components such as the columns of the racking determines the overall load-bearing capacity of the racking. The deviation of the beam length will affect the installation of the upper shelf and the force distribution of the overall structure. Therefore, a distance meter is needed to measure the length of the beam to prevent the deformation of the beam and ensure that the beam length can ensure the connection parts (such as bolts, hanging plates, etc.) It works in the correct position to form a stable connection between the beam and the column; since the beam is installed on the column, the rangefinder needs to be installed between it and the column during the detection of the beam to ensure that the rangefinder can accurately and stably measure the beam. However, during the installation of the rangefinder, the bolts or other shelf components near the column and the beam will cause the position of the rangefinder to be slightly adjusted in order to avoid the bolts or other shelf components, resulting in a deviation from the designed installation position, thereby causing the detection field of view of the rangefinder and the beam to change, and it cannot accurately cover the key parts of the beam, affecting the accuracy of the beam length measurement.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0013] 1. The present invention, through the arrangement of the stabilizing assembly, the crossbeam, and the rangefinder, can achieve the installation of the rangefinder without deliberately avoiding the bolts on the surface of the column. This facilitates the accurate installation of the rangefinder in the predetermined position, prevents the installation position of the rangefinder from deviating from the crossbeam, and prevents the rangefinder from changing the field of view of the rangefinder. This ensures that the rangefinder accurately covers the key parts of the crossbeam, facilitates the detection of the deformation degree of the crossbeam, and improves the accuracy of the detection of the crossbeam length.

[0014] 2. The present invention utilizes a relocation assembly, a rangefinder, an ear plate clamp, a base frame, and a column to allow the base frame and the ear plate clamp to be repositioned without changing the position of the rangefinder. As the angles of the ear plate clamp and the base frame change, the rangefinder can be adjusted to a relatively open position on the column when space around the column is limited, preventing obstruction by surrounding objects. This facilitates unimpeded detection of the beam length by the rangefinder, thereby improving detection accuracy and reliability.

[0015] 3. The present invention, through the arrangement of the friction column, the lug clamp, the rangefinder, and the column, enables relative motion between the friction column and the column, thereby generating frictional resistance to slow down the descent speed of the rangefinder. This facilitates the operator to better control the descent speed and position during the descent of the rangefinder, ensuring that the operator has sufficient time to observe and adjust the status of the rangefinder, ensuring that the detection work is carried out according to the predetermined plan, and enabling the rangefinder to move smoothly to different detection positions, thereby improving detection accuracy.

[0016] 4. The present invention maintains an inclination between the friction column and the shifting assembly through the arrangement of the shifting assembly, the arc inlay, the distance meter, and the arc inlay, thereby adjusting the arc inlay to a more appropriate height and position on the column. This allows the arc inlay to maintain an appropriate position with other shelf components near the column and the crossbeam, thereby adapting to different column structures.

[0017] 5. The present invention utilizes the arrangement of a shifting assembly, an arc-shaped inlay, a friction column, and a vertical column. The arc-shaped inlay moves to synchronously move the friction column mounted on its exterior toward the exterior of the vertical column. This allows for adjustment of the pressure between the friction column and the vertical column, ensuring that the contact force between the friction column and the vertical column is always moderate. This further enhances the stability between the friction column and the vertical column, enabling the rangefinder to accurately detect the length of the crossbeam column.

[0018] 6. The present invention, through the arrangement of the ear plate clamp, the soft pad, the column and the rangefinder, can achieve the interference between the middle part of the ear plate clamp and the column and the bolts on the outside of the column, and the two ear plate clamps are matched with the column and the bolts on the outside of the column in a slope, so that the ear plate clamp can maintain a stable connection with the column, preventing the bolts from occupying a certain space around the column, which makes the available operating space smaller when the rangefinder is installed, thereby ensuring the accuracy of the rangefinder's detection results of the beam column length.

[0035] 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 with reference to the accompanying drawings.

[0036] The present invention provides Figure 1 、 Figure 3 and Figure 4 The device for detecting the length of a beam of a three-dimensional shelf shown in the figure comprises a column 1 and a beam 11. A distance meter 12 for detecting the length of the beam 11 is installed on one side of the column 1. A stabilizing component 2 is connected between the distance meter 12 and the column 1. The stabilizing component 2 comprises two ear plate clamps 22 symmetrically mounted on the outside of the column 1. The ear plate clamps 22 are used to maintain a stable connection with the columns 1 of different profiles, so that the distance meter 12 can accurately measure the length of the beam 11. The distance meter 12 and the two ear plate clamps 22 are connected to each other. A base frame 21 is commonly connected between them, which is used to maintain the staggered connection between the rangefinder 12 and the column 1: a slider 25 that cooperates with the ear plate clamp 22 is slidably connected to one side of the base frame 21, and a diamond-shaped rocker 27 is rotatably connected to the middle part of one side of the base frame 21. A shaft column 28 is installed on the side of the ear plate clamp 22 close to the slider 25. A connecting rod 24 is commonly sleeved between the shaft column 28 and the rocker 27. A servo motor 26 is fixedly connected to the side of the base frame 21 away from the rocker 27, and the servo motor 26 is used to drive the rocker 27 to rotate;

[0037] The number of the ear plate clamps 22, the slider 25, the shaft column 28 and the connecting rod 24 is two, and the ear plate clamps 22, the slider 25, the shaft column 28 and the connecting rod 24 are staggeredly arranged outside the rocker 27 and the base frame 21;

[0038] The specific structure and principle of the rangefinder 12 are all prior art, so they are not described in detail in this application. Currently, in the measurement of beam length, the process of the rangefinder 12 generally includes the following steps:

[0039] 1. Install the distance meter 12: Install the distance meter 12 on the column 1 to ensure that the instrument is stable;

[0040] 2. Aligning the target: Aim the laser beam at the reflection point of the target object (such as a prism, reflector or target surface) through the sight or display screen of the rangefinder 12;

[0041] 3. Trigger distance measurement: Press the trigger button of the rangefinder 12 to emit the laser beam;

[0042] 4. Receiving reflected light: The rangefinder 12 receives the laser signal reflected from the target;

[0043] 5. Time difference measurement: The internal circuit of the rangefinder 12 calculates the time difference of the laser round trip;

[0044] 6. Automatically calculate the target distance based on the time difference and the speed of light, and display the result on the screen;

[0045] 7. Record data: Record the measurement results in a notebook or electronic device.

[0046] refer to Figure 1 、 Figure 3 and Figure 4 As shown, when there is an adjustment bolt near the connection between the column 1 and the crossbeam 11, and the rangefinder 12 needs to be installed on the outside of the column 1 for detecting the length of the crossbeam 11, the servo motor 26 drives the rocker 27 to rotate along one side of the base frame 21, and then the rocker 27 rotates to pull the two connecting rods 24 to move synchronously, so that the two connecting rods 24 move alternately along the outside of the rocker 27, and the two connecting rods 24 and the rocker 27 form a parallelogram motion. At this time, the two connecting rods 24 move to pull the two shaft columns 28 to move toward or relative to each other, and the two shaft columns 28 drive the two sliders 25 to move, and the two sliders 25 drive the two ear plate clamps 22 to approach the outside of the column 1, so that the two ear plate clamps 22 are against the corner of the column 1. The ear plate clamp 22 is used to contact the corner of the column 1 tightly, and a gap is maintained between the column 1 and the ear plate clamp 22 near the middle, and the gap between the column 1 and the ear plate clamp 22 is used to contact the bolts. Then the rangefinder 12 is stably installed on the outside of the column 1 by the stabilizing component 2 to detect the deformation degree of the beam column 11, ensuring that the rangefinder 12 accurately detects the length of the beam column 11; during the installation of the rangefinder 12, there is no need to deliberately avoid the bolts on the surface of the column 1, which is conducive to the accurate installation of the rangefinder 12 to the predetermined position, and prevents the installation position of the rangefinder 12 from deviating from the beam column 11, which changes the field of view of the rangefinder 12 and ensures that the rangefinder 12 accurately covers the key parts of the beam column 11.

[0047] refer to Figure 1 、 Figure 3 and Figure 4As shown, the ear plate clip 22 is set to a C-shaped structure, and a soft pad 23 is fixedly connected to the side of the ear plate clip 22 close to the column 1, and the soft pad 23 itself is deformed to allow the ear plate clip 22 to fit tightly against the exterior of the column 1;

[0048] refer to Figure 1 、 Figure 3 and Figure 4 As shown, the ear plate clamp 22 is set to a C-shaped structure, which is used to provide another locking method during the locking process of the above-mentioned ear plate clamp 22 and the column 1. First, the two symmetrical ear plate clamps 22 are narrow at the ends, expanded in the middle and narrow at the tail. Then the two ear plate clamps 22 are attached to the outside of the column 1. At this time, the ends of the two ear plate clamps 22 are in conflict with the outside of the column 1, and the middle parts of the two ear plate clamps 22 are in conflict with the column 1 and the bolts on the outside of the column 1. Moreover, the two ear plate clamps 22 are matched with the column 1 and the bolts on the outside of the column 1 in a slope, so that the ear plate clamps 22 can be with The column 1 remains stably connected to prevent the bolts from occupying a certain space around the column 1, which makes the available operating space for the rangefinder 12 smaller when it is installed. At the same time, the distance between the rangefinder 12 and the crossbeam 11 is also adjusted synchronously, which is conducive to fixing the rangefinder 12 to a specified position outside the column 1, making it convenient and free to adjust the position of the rangefinder 12, reducing the difficulty of alignment during the installation of the rangefinder 12, and preventing the angular deviation of the rangefinder 12 from changing the emission direction of the detection light or signal, thereby ensuring the accuracy of the rangefinder 12's detection result of the crossbeam 11.

[0049] refer to Figure 3 and Figure 5 As shown, a migration component 5 for driving the base frame 21 to rotate is installed at the bottom of the rangefinder 12. The migration component 5 includes an arc-shaped stabilizing frame 51 fixedly connected to the bottom end of the rangefinder 12. An arc frame 52 is installed at the top of the base frame 21, and the arc frame 52 is movably connected to the stabilizing frame 51. A migration groove 53 is provided at the top of the stabilizing frame 51. A positioning seat 58 is fixedly connected to the top of the arc frame 52, and the positioning seat 58 is located inside the migration groove 53; a limiting groove 55 is also provided inside the migration groove 53, and a limiting frame 56 is slidably connected inside the limiting groove 55. A threaded rod 54 is screwed on the top of the stabilizing frame 51, and a screw groove 57 is provided on the top of the limiting frame 56 and the positioning seat 58 for screwing the threaded rod 54 into. A contact plate 59 is fixedly connected to the top of the threaded rod 54, and the bottom of the contact plate 59 contacts the top of the stabilizing frame 51.

[0050] In addition, the ear plate clamp 22 drives the retarder component 3 to adjust its position along the exterior of the column 1 synchronously under the movement of the migration component 5, further improving the contact between the retarder component 3 and different positions of the exterior of the column 1, so as to facilitate the retarder component 3 to maintain stable contact with the exterior of the column 1;

[0051] refer to Figure 3 and Figure 5 As shown, when the installation position of the ear plate clamp 22 and the outside of the column 1 is adjusted, the interference plate 59 is first rotated to drive the threaded rod 54 to screw together along the inside of the screw groove 57, and then the threaded rod 54 is screwed together and moved upward along the screw groove 57 opened at the top of the positioning seat 58, and the threaded rod 54 is synchronously moved upward along the screw groove 57 opened at the top of the limiting frame 56. At this time, the threaded rod 54 moves to push the interference plate 59 to move upward, and the bottom of the interference plate 59 loses its interference with the top of the stabilizing frame 51, and pushes the arc frame 52 to move it along the bottom of the stabilizing frame 51, so that the arc frame 52 moves and drives the positioning seat 58 , the limiting frame 56, the threaded rod 54 and the contact plate 59 move synchronously. In addition, the limiting frame 56 moves along the internal guide of the limiting groove 55, so that the contact plate 59 can move along the external guide of the stabilizing frame 51, and then the position of the base frame 21 and the ear plate clamp 22 is changed without changing the position of the rangefinder 12. As the angle of the ear plate clamp 22 and the base frame 21 changes, when the space around the column 1 is limited, it can be adjusted to other relatively open positions of the column 1 for installation to prevent obstruction by surrounding objects, which is conducive to the rangefinder 12 to detect the length of the beam column 11 without hindrance, thereby improving the accuracy and reliability of the detection.

[0052] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, a deceleration component 3 for slowly moving the rangefinder 12 along one side of the column 1 is commonly connected between the stabilizing component 2 and the column 1. The deceleration component 3 includes an arc inlay 31 in contact with the outside of the column 1. Friction columns 33 are installed on the corresponding sides of the arc inlay 31 and the arc frame 52, and the exteriors of the two friction columns 33 conflict with the exterior of the column 1 to generate friction resistance, which is used for slowly moving the rangefinder 12 along the exterior of the column 1. A bracket 32 ​​is fixedly connected to the corresponding sides of the arc inlay 31 and the arc frame 52. A curved rod 34 is connected to the exterior of the friction column 33, and the curved rod 34 is configured as an L-shaped structure. A moving groove 301 is opened on the side of the bracket 32 ​​close to the column 1. A connecting column 35 is installed inside the moving groove 301. The top of the curved rod 34 is located inside the moving groove 301 and is sleeved on the exterior of the connecting column 35.

[0053] The number of the inner arc embedded frame 31 of the deceleration assembly 3 is one, the number of the friction posts 33 is two, and the remaining bent rods 34, connecting posts 35, brackets 32, movable grooves 301, ball sleeve posts 39, connecting balls 38, support springs 37 and contact frames 36 are all four groups;

[0054] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, when the rangefinder 12 needs to measure different positions of the crossbeam column 11 and the ear plate clamp 22 and the column 1 remain loose, the outer parts of the two friction columns 33 first keep in contact with the outer parts of the column 1, and then the friction columns 33 drive the curved rod 34 to swing along the outer part of the connecting column 35. At this time, the ball sleeve column 39 installed on the top of the curved rod 34 approaches the side of the contact frame 36 under the swing of the curved rod 34, and the elastic force of the supporting spring 37 itself can give a driving force to one side of the connecting ball 38 to generate a reaction force on one side of the curved rod 34. In addition, the supporting spring 37 drives the curved rod 34 to drive the friction column 33 to the outer part of the column 1, so that the outer part of the friction column 33 applies a moving pressure to the outer part of the column 1, so that the two are in close contact. The contact between the two friction columns 33 and the column 1 increases the friction resistance of the contact parts between the two friction columns 33 and the column 1. In addition, the looseness between the ear plate clamp 22 and the column 1 releases the locking state between the rangefinder 12 and the column 1. Then the rangefinder 12 will move downward along the outside of the column 1 under the action of gravity. Subsequently, relative movement will occur between the friction columns 33 and the column 1, thereby generating friction resistance to slow down the descent speed of the rangefinder 12. This is beneficial for the operator to better control the descent speed and position during the descent of the rangefinder 12, ensuring that the operator has enough time to observe and adjust the status of the rangefinder 12, ensuring that the detection work is carried out according to the predetermined plan, and enabling the rangefinder 12 to move smoothly to different detection positions, thereby improving the detection accuracy.

[0055] refer to Figure 7 、 Figure 8 and Figure 9 As shown, a shifting assembly 4 is commonly connected between the rangefinder 12 and the deceleration assembly 3, and the shifting assembly 4 is used to shift the deceleration assembly 3 to an alternating position with the column 1 and the crossbeam 11. The shifting assembly 4 includes a screw hole 43 provided on one side of the arc embedded frame 31. The exterior of the stabilizing frame 51 is fixedly connected to an articulated frame 42, and the exterior of the articulated frame 42 is articulated to a bent frame 44. The exterior of the bent frame 44 has a threaded groove 45. The exterior of the arc embedded frame 31 is screwed with a threaded bolt 41, and the threaded bolt 41 is screwed into the interior of the threaded groove 45 corresponding to the screw hole 43 through the screw hole 43.

[0056] refer to Figure 7 、 Figure 8 and Figure 9As shown, when there are other shelf components near the crossbeam 11 and the column 1, the bent frame 44 is first pushed to rotate it along the outside of the hinge frame 42, so that the angle between the bent frame 44 and the hinge frame 42 is adjusted, and then the threaded bolt 41 is rotated to screw it along the screw hole 43 and the thread groove 45. At this time, the threaded bolt 41 moves along the inside of the screw hole 43 and the thread groove 45, and the threaded bolt 41 moves to push the arc embedded frame 31 closer to the outside of the column 1. At this time, the arc embedded frame 31 and the threaded bolt 41 and the hinge frame 42 maintain an inclined state. In this state, the arc embedded frame 31 can be adjusted to a more appropriate height and position on the column 1, so that the arc embedded frame 31 maintains a suitable position with other shelf components near the column 1 and the crossbeam column 11, thereby adapting to different column 1 structures; in addition, the movement of the arc embedded frame 31 synchronously moves the friction column 33 installed on its outside toward the outside of the column 1, which can adjust the pressure between the friction column 33 and the column 1, ensuring that the contact force between the friction column 33 and the column 1 is always moderate, further improving the stability between the friction column 33 and the column 1.

[0057] Working principle:

[0058] When in use;

[0059] refer to Figure 3 and Figure 5 As shown, the migration component 5 can realize the change of the position of the base frame 21 and the ear plate clamp 22 without changing the position of the rangefinder 12. As the angle of the ear plate clamp 22 and the base frame 21 changes, when the space around the column 1 is limited, it can be adjusted to other relatively open positions of the column 1 for installation to prevent obstruction by surrounding objects, which is conducive to the rangefinder 12 to detect the length of the beam column 11 without hindrance.

[0060] refer to Figure 1 、 Figure 3 and Figure 4 As shown, when there is an adjustment bolt near the connection between the column 1 and the crossbeam 11, and the rangefinder 12 needs to be installed on the outside of the column 1 for detecting the length of the crossbeam 11, the servo motor 26 drives the rocker 27 to rotate along one side of the base frame 21, and then the rocker 27 rotates to pull the two connecting rods 24 to move synchronously, so that the two connecting rods 24 move alternately along the outside of the rocker 27, and the two connecting rods 24 and the rocker 27 form a parallelogram motion. At this time, the two connecting rods 24 move and pull the two shaft columns 28 to move toward or relative to each other, and the two shaft columns 28 drive the two sliders 25 to move, and the two sliders 25 drive the two ear plate clamps 22 to approach the outside of the column 1, so that the two ear plate clamps 22 contact the corners of the column 1, which are used to tightly contact the corners of the column 1, and a gap is maintained near the middle of the ear plate clamp 22 with the column 1, and the gap between the column 1 and the ear plate clamp 22 is used to contact the bolts.

[0061] refer to Figure 7 、 Figure 8 and Figure 9 As shown, when there are other shelf components near the crossbeam 11 and the column 1, first push the bent frame 44 to rotate it along the outside of the hinged frame 42, so that the angle between the bent frame 44 and the hinged frame 42 is adjusted, and then rotate the threaded bolt 41 to screw it into the screw hole 43 and the threaded groove 45. At this time, the threaded bolt 41 moves along the inside of the screw hole 43 and the threaded groove 45, and the threaded bolt 41 moves to push the arc embedded frame 31 closer to the outside of the column 1. At this time, the arc embedded frame 31 and the threaded bolt 41 and the hinged frame 42 maintain an inclined state, and the arc embedded frame 31 can be adjusted to a more suitable height and position on the column 1, so that the arc embedded frame 31 and other shelf components near the column 1 and the crossbeam 11 maintain a suitable position.

[0062] refer to Figure 6 、 Figure 8 and Figure 9 As shown, when the rangefinder 12 needs to measure different positions of the crossbeam 11, and the shifting assembly 4 maintains stable contact between the friction column 33 and the column 1, and maintains a loose state between the ear plate clamp 22 and the column 1, the friction column 33 drives the curved rod 34 to swing along the outside of the connecting column 35. At this time, the ball sleeve column 39 installed on the top of the curved rod 34 approaches the side of the contact frame 36 under the swing of the curved rod 34, and the elastic force of the supporting spring 37 itself can give a driving force to the side of the connecting ball 38 to generate a reaction force on one side of the curved rod 34. In addition, the supporting spring 37 drives the curved rod 34 to drive the friction column 33 to approach the outside of the column 1, so that the outside of the friction column 33 The outer part of the column 1 is subjected to moving pressure to make the two contact closely, thereby increasing the friction resistance of the contact parts between the two friction columns 33 and the column 1. In addition, the looseness between the ear plate clamp 22 and the column 1 releases the locking state between the rangefinder 12 and the column 1. Then, the rangefinder 12 moves downward along the outer part of the column 1 under the action of gravity. Subsequently, relative motion occurs between the friction columns 33 and the column 1, thereby generating friction resistance to slow down the descent speed of the rangefinder 12. This is beneficial for the operator to better control the descent speed and position of the rangefinder 12 during the descent process, ensuring that the operator has sufficient time to observe and adjust the status of the rangefinder 12.

Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
