Description

Technical Field

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

[0002] A three-dimensional shelf is a high-density and multi-level warehousing storage device that improves the storage capacity and space utilization rate of a warehouse by making full use of the vertical space; it is usually composed of components such as columns, crossbeams, shelves, and pallet supports; among them, the crossbeam is one of the main load-bearing components of the three-dimensional shelf, and its length, together with other components such as the columns of the shelf, determines the overall load-bearing capacity of the shelf. Deviations in the length of the crossbeam will affect the installation of the upper shelf and the force distribution of the overall structure. Therefore, a rangefinder is required to measure the length of the crossbeam to prevent the crossbeam from being deformed, and to ensure that the length of the crossbeam can ensure that connecting components (such as bolts, hanging pieces, etc.) play a role in the correct position, so as to form a stable connection between the crossbeam and the column; since the crossbeam is installed on the column, when the rangefinder detects the crossbeam, it needs to be installed between it and the column to ensure accurate and stable measurement of the crossbeam by the rangefinder. However, during the installation process of the rangefinder, bolts or other shelf components near the column and the crossbeam will slightly adjust the position of the rangefinder in order to avoid bolts or other shelf components, resulting in a deviation from the designed installation position, thus causing a change in the detection visual field range between the rangefinder and the crossbeam, and being unable to accurately cover the key parts of the crossbeam, affecting the accuracy of the crossbeam length measurement.

[0016] 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.

[0017] The present invention providesFigure 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 column 11. A distance meter 12 for detecting the length of the beam column 11 is installed on one side of the column 1. A stable measuring component 2 is connected between the distance meter 12 and the column 1. The stable measuring component 2 comprises two ear plate clips 22 symmetrically installed on the outside of the column 1. The ear plate clips 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 column 11. The distance meter 12 and the two ear plate clips 22 are connected to each other. A base frame 21 is commonly connected between them, which is used to keep the rangefinder 12 and the column 1 staggered and connected: a slider 25 matching the ear plate clamp 22 is slidably connected to one side of the base frame 21, 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, and 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; The number of the ear plate clamp 22, the slider 25, the shaft column 28 and the connecting rod 24 is two, and the ear plate clamp 22, the slider 25, the shaft column 28 and the connecting rod 24 are staggeredly arranged outside the rocker 27 and the bottom frame 21; 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 the beam length, the process of the rangefinder 12 generally includes the following steps: 1. Install the distance meter 12: Install the distance meter 12 on the column 1 to ensure that the instrument is stable; 2. Aligning the target: Align the laser beam to the reflection point of the target object (such as a prism, a reflector or a target surface) through the sight or display screen of the rangefinder 12; 3. Triggering distance measurement: Pressing the trigger button of the distance meter 12 to emit the laser beam; 4. Receiving reflected light: The rangefinder 12 receives the laser signal reflected from the target; 5. Time difference measurement: The internal circuit of the rangefinder 12 calculates the time difference of the laser round trip; 6. Automatically calculate the target distance based on the time difference and the speed of light, and display the result on the display screen; 7. Record data: Record the measurement results in a notebook or electronic device.

[0018] refer to Figure 1 , Figure 3 and Figure 4As shown, when there are adjustment bolts near the connection between the column 1 and the crossbeam column 11, and the distance measuring instrument 12 needs to be installed outside the column 1 for detecting the length of the crossbeam column 11, the servo motor 26 drives the rocker 27 to rotate along one side of the chassis 21. 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 a parallelogram motion is formed between the two connecting rods 24 and the rocker 27. At this time, the two connecting rods 24 move to pull the two shaft columns 28 to move towards or away from 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. Thus, the two ear plate clamps 22 abut against the corner of the column 1, used to tightly abut against the corner of the column 1, and there is a gap between the middle part of the ear plate clamp 22 and the column 1, and the gap between the column 1 and the ear plate clamp 22 is used to abut against the bolt. Then, the distance measuring instrument 12 is stably installed outside the column 1 by the stable measuring component 2, used to detect the deformation degree of the crossbeam column 11, ensuring the accurate detection of the length of the crossbeam column 11 by the distance measuring instrument 12; during the installation process of the distance measuring instrument 12, there is no need to deliberately avoid the bolts on the surface of the column 1, which is beneficial to accurately installing the distance measuring instrument 12 to the predetermined position, preventing deviation between the installation position of the distance measuring instrument 12 and the crossbeam column 11, causing the change of the detection visual field range of the distance measuring instrument 12, and ensuring that the distance measuring instrument 12 accurately covers the key parts of the crossbeam column 11.

[0019] Reference Figure 1 、 Figure 3 and Figure 4 As shown, the ear plate clamp 22 is set as a C-shaped structure, and a soft pad 23 is fixedly connected to the side of the ear plate clamp 22 close to the column 1, and the soft pad 23 deforms itself for the ear plate clamp 22 to closely fit with the outside of the column 1; Reference Figure 1 、 Figure 3 and Figure 4As shown, the ear plate clamp 22 is set to a C-shaped structure, which is used for 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 maintains a stable connection to prevent the bolts from occupying a certain space around the column 1, which makes the available operating space smaller when the rangefinder 12 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, and conveniently and freely adjusting the position of the rangefinder 12, reducing the difficulty of alignment during the installation of the rangefinder 12, preventing the angle deviation of the rangefinder 12 from changing the emission direction of the detection light or signal, and ensuring the accuracy of the rangefinder 12's detection result of the crossbeam 11.

[0020] 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, and 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 and the stabilizing frame 51 are movably connected, a migration groove 53 is opened 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 opened 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 for the threaded rod 54 to be screwed into the top of the limiting frame 56 and the positioning seat 58, and 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; In addition, the ear plate clamp 22 drives the deceleration component 3 to synchronously adjust its position along the outside of the column 1 under the movement of the migration component 5, further improving the contact between the deceleration component 3 and different positions of the outside of the column 1, so as to facilitate the deceleration component 3 to maintain stable contact with the outside of the column 1; refer to Figure 3 and Figure 5As shown, when the installation position of the ear plate clamp 22 and the outer part of the column 1 is adjusted, the friction 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 friction plate 59 to move upward, and the bottom of the friction plate 59 loses the effect of friction 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 to drive the positioning seat 58 , the limiting frame 56, the threaded rod 54 and the abutment plate 59 move synchronously. In addition, the limiting frame 56 moves along the internal guide of the limiting groove 55, so that the abutment 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 angles of the ear plate clamp 22 and the base frame 21 change, 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.

[0021] 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, and the deceleration component 3 includes an arc embedded frame 31 contacting the outside of the column 1, and the arc embedded frame 31 and the arc frame 52 are both installed with friction columns 33 on the corresponding sides, and the outsides of the two friction columns 33 collide with the outside of the column 1 to generate friction resistance, which is used for the rangefinder 12 to slowly move along the outside of the column 1, and the arc embedded frame 31 and the arc frame 52 are both fixedly connected with a bracket 32 on the corresponding sides, and the outside of the friction column 33 is connected with a curved rod 34, and the curved rod 34 is set to an L-shaped structure, and a moving groove 301 is opened on the side of the bracket 32 close to the column 1, and a connecting column 35 is installed inside the moving groove 301, and the top of the curved rod 34 is located inside the moving groove 301 and is sleeved on the outside of the connecting column 35; The number of the inner arc embedded frame 31 of the deceleration component 3 is one, the number of the friction column 33 is two, and the remaining bent rod 34, the connecting column 35, the bracket 32, the moving groove 301, the ball sleeve column 39, the connecting ball 38, the support spring 37 and the contact frame 36 are all four groups; 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 in a loose state, first, the outsides of the two friction columns 33 are in contact with the outside of the column 1, and then the friction column 33 drives the bent 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 bent rod 34 approaches one side of the abutment frame 36 under the swing of the bent 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, which is used to generate a reaction force on one side of the bent rod 34, and the supporting spring 37 drives the bent 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 applies a moving pressure to the outside of the column 1, so that the two are in close contact. The contact between the two friction columns 33 and the column 1 is increased, and the friction resistance of the contact parts between the two friction columns 33 and the column 1 is increased. 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 outside of the column 1 under the action of gravity, and then relative movement occurs between the friction column 33 and the column 1, thereby generating friction resistance to slow down the descent speed of the rangefinder 12, which 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 state 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.

[0022] refer to Figure 7 , Figure 8 and Figure 9 As shown, a moving assembly 4 is commonly connected between the rangefinder 12 and the deceleration assembly 3, and the moving assembly 4 is used to move the deceleration assembly 3 and the staggered position of the column 1 and the crossbeam column 11, and the moving assembly 4 includes a screw hole 43 opened on one side of the arc embedded frame 31, the outside of the stabilizing frame 51 is fixedly connected with an articulated frame 42, the outside of the articulated frame 42 is hinged with a bent frame 44, the outside of the bent frame 44 is provided with a threaded groove 45, the outside of the arc embedded frame 31 is screwed with a threaded bolt 41, and the threaded bolt 41 is screwed into the inside of the threaded groove 45 corresponding to the screw hole 43 through the screw hole 43; refer to Figure 7 , Figure 8 and Figure 9As shown, when there are other shelf components near the crossbeam column 11 and the upright column 1, first push the bent frame 44 to rotate it along the outside of the hinge frame 42, so as to adjust the angle between the bent frame 44 and the hinge frame 42. Then rotate the threaded bolt 41 to screw it into 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 movement of the threaded bolt 41 pushes the arc-shaped embedded frame 31 to approach the outside of the upright column 1. At this time, the arc-shaped embedded frame 31 and the threaded bolt 41 are inclined with respect to the hinge frame 42, and the arc-shaped embedded frame 31 can be adjusted to a more suitable height and position on the upright column 1, so that the arc-shaped embedded frame 31 maintains a proper position with other shelf components near the upright column 1 and the crossbeam column 11, thus adapting to different structures of the upright column 1. In addition, the movement of the arc-shaped embedded frame 31 synchronously moves the friction column 33 installed on its outside closer to the outside of the upright column 1, which can adjust the pressure between the friction column 33 and the upright column 1, ensuring that the contact force between the friction column 33 and the upright column 1 is always moderate, and further enhancing the stability between the friction column 33 and the upright column 1.

[0023] Working principle: When in use; Refer to Figure 3 and Figure 5 As shown, through the migration component 5, the positions of the chassis 21 and the ear plate clamp 22 can be changed without changing the position of the rangefinder 12. As the angle between the ear plate clamp 22 and the chassis 21 changes, when the space around the upright column 1 is limited, it can be adjusted to other relatively open positions around the upright column 1 for installation, preventing the occlusion of surrounding objects, which is beneficial for the rangefinder 12 to detect the length of the crossbeam column 11 unobstructed.

[0024] Refer to Figure 1 、 Figure 3 and Figure 4 As shown, when there is an adjustment bolt near the connection between the upright column 1 and the crossbeam column 11, and the rangefinder 12 needs to be installed outside the upright column 1 for detecting the length of the crossbeam column 11, the servo motor 26 drives the rocker 27 to rotate along one side of the chassis 21. Then the rocker 27 rotates to pull the two connecting rods 24 to move synchronously, so that the two connecting rods 24 move crosswise along the outside of the rocker 27, and the two connecting rods 24 and the rocker 27 move in a parallelogram motion. At this time, the two connecting rods 24 move to pull the two axle columns 28 to move towards or away from each other, and the two axle 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 upright column 1. Thus, the two ear plate clamps 22 are in contact with the corner of the upright column 1, used to tightly contact the corner of the upright column 1, and there is a gap between the middle part of the ear plate clamp 22 and the upright column 1, and the gap between the upright column 1 and the ear plate clamp 22 is used to contact the bolt.

[0025] Refer to Figure 7 、 Figure 8 and Figure 9As 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 along 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 frame 31 to the outside of the column 1. At this time, the arc frame 31 and the threaded bolt 41 maintain an inclined state with the hinged frame 42, and the arc frame 31 can be adjusted to a more suitable height and position on the column 1, so that the arc frame 31 and other shelf components near the column 1 and the crossbeam 11 maintain a suitable position.

[0026] refer to Figure 6 , Figure 8 and Figure 9 As shown, when the rangefinder 12 needs to measure different positions of the crossbeam column 11, and the shifting assembly 4 keeps the friction column 33 in stable contact with the column 1, and keeps the ear plate clamp 22 and the column 1 in a loose state, the friction column 33 drives the bent 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 bent rod 34 approaches one side of the abutment frame 36 under the swing of the bent 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, which is used to generate a reaction force on one side of the bent rod 34, and the supporting spring 37 drives the bent rod 34 to drive the friction column 33 to approach the outside of the column 1, so that the outer side of the friction column 33 The outer part of the column 1 is applied with moving pressure to make the two closely contact, 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, and then relative movement is generated between the friction column 33 and the column 1, thereby generating friction resistance to slow down the descent speed of the rangefinder 12, which is beneficial for the operator to better control the descent speed and position during the descent of the rangefinder 12, and ensure that the operator has enough time to observe and adjust the state of the rangefinder 12.
