Description

Technical Field

[0001] This invention relates to the field of surveying and measurement technology, specifically to a surveying and measurement device for a beam bracket structure. Background Technology

[0002] In the construction of the continuous rigid frame of the portal pier with concealed cap beam, block 0 serves as the connecting hub between the continuous rigid frame and the portal pier, and its construction quality plays a crucial role in the construction of both the crossbeam and the continuous rigid frame. In coastal areas, the construction of the crossbeam and block 0 of the concealed portal pier is significantly affected by overlapping construction activities and the geological conditions of deep silt layers. Traditional ground-supported methods cannot meet the construction clearance requirements under overlapping construction conditions, and the construction workload is large. Traditional bracket schemes require diagonal bracing on the pier body, but since block 0 is embedded in the middle of the portal pier's crossbeam, the diagonal bracing lacks a support surface, making it impossible to organize the construction of block 0. Therefore, the traditional bracket scheme was modified and upgraded to a cantilevered main crossbeam bracket structure. This system combines pre-embedded corbels, a cantilevered main crossbeam, a reinforced Bailey bridge main beam, and transverse distribution beams to form a single-span cantilevered main crossbeam bracket construction system. This solves the problem of the lack of a support surface for the diagonal bracing structure in the traditional bracket scheme, meets the space requirements for overlapping construction operations, greatly facilitates construction organization, and saves construction costs.

[0003] In the early stages of construction, it is necessary to conduct a survey and measurement of the construction site to confirm the conditions for erecting the crossbeam bracket. Currently, there is a lack of integrated equipment capable of conducting such surveys and measurements. It is often necessary to manually build a matching frame and then manually carry a distance measuring instrument to measure the parallelism of the support brackets for installing the crossbeam bracket to ensure smooth installation.

[0016] 1. This crossbeam bracket structure surveying and measuring device, by setting two sets of movable uprights and setting a walking component between the movable uprights, drives the entire device to move forward or backward smoothly without manual pushing, effectively reducing the labor intensity of operators and improving the accuracy and stability of movement.

[0017] 2. This crossbeam bracket structure surveying and measuring device, by setting a ranging component between two sets of movable vertical plates, achieves high-precision measurement of the crossbeam bracket through a multi-dimensional adjustment structure. The ranging component is driven by a motor to synchronously drive two sets of adjusting screws, which support the two measuring square tubes on both sides of the ranging probe to move towards or away from each other, thereby adjusting the distance between the two sets of ranging probes, thus adapting to the width measurement requirements of crossbeam brackets of different specifications.

[0018] 3. This crossbeam bracket structure surveying and measuring device, through the installation of a mechanical indicating device, allows the sliding rod to move the pointer synchronously when the ranging probe extends or retracts.

Simultaneously, the relative movement between the pointer and the scale plate reflects the probe's dynamic contact state in real time, facilitating the operator's assessment of the measurement process's stability and improving the straightness of the crossbeam bracket to be installed, as well as the flatness of its ends and the matching degree with the mounting surface.

[0019] 4. This crossbeam bracket structure surveying and measuring device, by setting eccentric wheels at both ends of the drive shaft, the eccentric wheels rotate synchronously when the drive shaft rotates, and push the top plate to move up and down through the eccentric action, thereby driving the first guide rod and the bracket to reciprocate, causing the scraper to vibrate in the up and down direction.

[0020] 5. This crossbeam bracket structure surveying and measuring device, by incorporating a wind turbine, generates enough airflow to meet the airflow requirements of the air holes, ensuring that the airflow smoothly reaches the inclined area of ​​the scraper and removes deposited materials. Simultaneously, this structure utilizes the movement power of the ranging component to drive the wind turbine, eliminating the need for an additional drive motor, simplifying the device structure, reducing energy consumption, and achieving coordinated control of cleaning and measurement actions. When the ranging component moves to the measurement position, the wind turbine synchronously generates airflow to clean the measurement area, ensuring the cleanliness of the measurement environment.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 9 The present invention discloses a surveying and measuring device for a beam bracket structure, comprising two sets of movable upright plates 1, with universal wheels 33 at the bottom of the movable upright plates 1, and a fixed plate 34 fixedly installed on one side of the outer wall of the movable upright plates 1. A lifting screw 42 is internally threaded onto the fixed plate 34, and the universal wheels 33 are rotatably installed at the bottom end of the lifting screw 42.

[0034] For example, during actual surveying operations, the height of the caster wheel 33 can be adjusted by rotating the lifting screw 42. When the device needs to be moved, the caster wheel 33 can be lowered to contact the ground, and the rolling characteristics of the caster wheel 33 can be used to achieve convenient transportation.

[0035] Optionally, the walking assembly includes a drive shaft 18, which is rotatably mounted between two sets of movable uprights 1. Two sets of drive rollers 19 are symmetrically mounted on the surface of the drive shaft 18. A second motor 20 is mounted on one side of one set of movable uprights 1. The second motor 20 is connected to the drive shaft 18 in a transmission connection. A synchronous pulley 22 is fixedly mounted on one end of the drive shaft 18. A synchronous pulley 22 is also mounted on the output shaft end of the second motor 20. A synchronous belt 21 is connected between the two sets of synchronous pulleys 22 in a transmission connection.

[0036] For example, in this embodiment, the second motor 20 drives the drive shaft 18 to rotate through the cooperation of the synchronous pulley 22 and the synchronous belt 21. The drive shaft 18 drives two sets of drive rollers 19 to rotate synchronously, thereby realizing the automatic walking function of the device along the crossbeam bracket structure. The entire device is driven to move forward or backward smoothly without manual pushing, which effectively reduces the labor intensity of the operators and improves the accuracy and stability of the movement.

[0037] It should be noted that, to ensure guidance during movement, guide flanges adapted to the edge of the crossbeam can be provided on the inner side of the rims of the two sets of drive rollers 19 to prevent lateral deviation of the device during movement. Meanwhile, deep groove ball bearings are installed at the connection points between the drive shaft 18 and the movable vertical plate 1 at both ends to reduce frictional resistance during rotation of the drive shaft 18, thereby improving transmission efficiency and the service life of components.

[0038] Optionally, a ranging assembly is provided between the two sets of movable upright plates 1. The ranging assembly includes two sets of first electric slides 2, which are connected between the two sets of movable upright plates 1. A movable plate 3 is connected to the first electric slide 2, and two sets of second electric slides 4 are installed on the movable plate 3. A first motor 5 is installed on the second electric slide 4. Two sets of measuring square tubes 6 are symmetrically arranged on both sides of the first motor 5. A ranging probe 7 is elastically and slidably connected to one end of each set of measuring square tubes 6.

[0039] For example, in this embodiment, the ranging component achieves high-precision measurement of the crossbeam bracket through a multi-dimensional adjustment structure. Specifically, two sets of first electric slides 2 are arranged parallel to each other along the transverse direction of the movable upright plate 1, and their sliders are rigidly connected to the movable plate 3. When the first electric slides 2 are started, they can drive the movable plate 3 to move smoothly along the width direction of the crossbeam. Two sets of second electric slides 4 are fixed to the surface of the movable plate 3 by bolts. These slides are arranged in a direction perpendicular to the first electric slides 2, and their sliders integrate the mounting base of the first motor 5. Driven by the second electric slides 4, the first motor 5 and the measuring square tube 6 can be linearly displaced along the length direction of the crossbeam to be installed. This, combined with the first electric slides 2, forms a two-dimensional plane position adjustment, ensuring that the ranging probe 7 can reach any measurement point on the surface of the crossbeam bracket installation position. The measuring square tube 6 is internally equipped with a guide groove and a compression spring. The slider at the tail of the ranging probe 7 is embedded in the groove to form a sliding fit. The two ends of the compression spring abut against the tail of the probe and the inner wall of the square tube, respectively. When the probe contacts the surface of the crossbeam, the spring generates elastic pressure, ensuring that the probe always maintains close contact with the measured surface and avoiding damage caused by rigid collisions. The ranging probe 7 has a built-in laser displacement sensor and a pressure sensor. The laser sensor can collect the distance data between the probe and the reference surface in real time, while the pressure sensor monitors the contact pressure value. When the pressure exceeds the set threshold, the system automatically controls the second electric slide 4 to move in the reverse direction, realizing the overload protection function.

[0040] Optionally, the first motor 5 has two sets of adjusting screws 8 internally connected to the transmission, and the adjusting screws 8 are connected to the measuring square tube 6 through an internal threaded sleeve.

[0041] For example, in this embodiment, the first motor 5 is a dual-output-shaft stepper motor. Its two output shafts are rigidly connected to the adjusting screws 8 via couplings. The outer surface of the adjusting screws 8 is machined with a T-shaped trapezoidal thread, forming a precision helical transmission with the internal threaded sleeve welded to the tail of the measuring square tube 6. When the first motor 5 rotates forward or backward, the two sets of adjusting screws 8 synchronously drive the measuring square tubes 6 on both sides to move towards or away from each other, thereby adjusting the distance between the two sets of ranging probes 7, thus adapting to the width measurement requirements of different specifications of crossbeam brackets.

[0042] It should be noted that the threaded transmission pair converts the rotational motion of the motor into linear displacement, which, combined with the pulse control characteristics of the motor, meets the prerequisites for high-precision measurement. Optionally, a reinforcing rib is provided at the connection between the internal threaded sleeve and the measuring square tube 6 to prevent structural deformation caused by long-term stress. The end of the adjusting screw 8 away from the motor is connected to the bearing seat on the moving plate 3 through a thrust ball bearing, forming a two-end support structure to prevent the screw from bending under axial force.

[0043] Example 2

[0044] This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1 to 9 It also includes a ranging probe 7 with a ranging rod 10 connected to one end, the ranging rod 10 and the measuring square tube 6 being slidably connected at the end, a sliding rod 11 connected to one end of the ranging rod 10, a positioning plate 12 installed inside the measuring square tube 6, the sliding rod 11 and the positioning plate 12 being slidably connected, and a first spring 13 being provided between the positioning plate 12 and the ranging rod 10.

[0045] In this embodiment, for example, the rod body of the ranging rod 10 forms a clearance fit with the guide hole at the end of the measuring square tube 6 to ensure smooth sliding without jamming. A limiting flange is provided near the probe end of the ranging rod 10 to prevent excessive extension and detachment. The other end is rigidly connected to the slide rod 11 to form a secondary guide structure, further improving the straightness of the displacement of the ranging probe 7. The first spring 13 is sleeved on the outside of the ranging rod 10. When the ranging probe 7 is not in contact with the measured surface, the spring is in a naturally extended state. When the probe contacts the surface and is compressed, the ranging rod 10 drives the slide rod 11 to compress the spring. The restoring force generated by the spring makes the probe fit tightly against the surface. At the same time, the linear relationship between the spring compression and the elastic force can help verify the measurement data of the pressure sensor, forming a dual pressure monitoring mechanism.

[0046] Optionally, a pointer 14 is connected to one end of the slide bar 11. The pointer 14 is set as an L-shaped plate and extends to the outside of the measuring square tube 6. A scale plate 15 is connected to one side of the outside of the measuring square tube 6. The pointer 14 and the scale plate 15 are matched.

[0047] In this embodiment, for example, the horizontal segment of the pointer 14 is fixed to the end of the slide bar 11 by welding, and the vertical segment serves as the indicating end, with the end machined into a sharp angle, pointing towards the scale line of the scale plate 15. The surface of the scale plate 15 is printed with alternating black and white scales, and the zero scale line corresponds to the pointer position in the natural state of the first spring 13. When the ranging probe 7 extends or retracts, the slide bar 11 drives the pointer 14 to move synchronously. The operator can visually read the displacement of the probe through the scale plate 15. This mechanical indication method can serve as a backup reading method for the electronic measurement system, allowing for rough measurements even in the event of sensor failure or power outage, thus improving the reliability of the device. Simultaneously, the relative movement between the pointer 14 and the scale plate 15 can reflect the dynamic contact state of the probe in real time, facilitating the operator's judgment of whether the measurement process is stable.

[0048] Optionally, the movable plate 3 is connected to support plates 9 on both sides, and a guide groove 36 is provided in the support plate 9. A slider 16 is slidably connected in the guide groove 36, and a pulley 17 is connected to the bottom of the slider 16. The pulley 17 is slidably disposed in the groove 41.

[0049] In this embodiment, for example, the support plate 9 is fixed on both sides of the movable plate 3, and the guide groove 36 is formed in the vertical section of the support plate 9. The slider 16 is fitted with the guide groove 36 with a clearance, and the bottom of the slider 16 is rotatably connected to the pulley 17. The pulley 17 is preferably made of polyurethane and fits with the groove 41 to form a guiding constraint. The groove 41 is formed on the top of the movable plate 1. When the first electric slide 2 drives the movable plate 3 to move, the support plates 9 on both sides move synchronously, the slider 16 slides in the guide groove 36, and the pulley 17 rolls along the guide rail in the groove 41, forming a four-point support auxiliary guiding system. This system can withstand the overturning moment generated by the movable plate 3 and the ranging component, prevent the slider of the first electric slide 2 from deforming due to excessive force on one side, ensure the stability of the entire ranging component during movement, and reduce vibration interference during measurement.

[0050] Example 3

[0051] This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1 to 9 It also includes a drive shaft 18 with both ends passing through the movable vertical plate 1. The scraping assembly includes eccentric wheels 23 fixedly installed at both ends of the drive shaft 18. The outer ring of the eccentric wheels 23 is attached to the top plate 24. A first guide plate 26 is symmetrically installed on one side of the movable vertical plate 1. A first guide rod 25 is connected to the top of the top plate 24. The first guide rod 25 and the first guide plate 26 are slidably connected. A second spring 27 is connected between the top plate 24 and the first guide plate 26. A support plate 28 is connected to the top of the first guide rod 25. A scraper 29 is connected to the top of the support plate 28.

[0052] In this embodiment, for example, the portions of the drive shaft 18 extending out of the movable vertical plate 1 are connected to the eccentric wheel 23 via flat keys. The eccentricity of the eccentric wheel 23 is set to 5mm, and the rim surface is nitrided to improve hardness. An arc-shaped contact plate is welded to the bottom of the top plate 24, forming line contact with the outer ring of the eccentric wheel 23. A wear-resistant rubber sheet is attached to the surface of the contact plate to reduce friction noise and improve contact reliability. Two first guide plates 26 are welded to the side of the movable vertical plate 1, with the spacing between them matching the width of the top plate 24. A first guide rod 25 passes through the guide hole of the first guide plate 26, and a linear bearing is installed in the guide hole to make the reciprocating motion of the first guide rod 25 smoother. A second spring 27 is sleeved on the outside of the first guide rod 25, with its two ends abutting against the top plate 24 and the first guide plate 26 respectively, ensuring that the top plate 24 is always in close contact with the eccentric wheel 23. When the drive shaft 18 rotates, the eccentric wheel 23 rotates synchronously, pushing the top plate 24 to move up and down through the eccentric action, which in turn drives the first guide rod 25 and the support plate 28 to reciprocate, causing the scraper 29 to vibrate in the up and down direction. Through the above-mentioned high-frequency micro-vibration, the scraper 29 can better remove stubborn stains from the surface of the crossbeam bracket to be installed, which can not only ensure the fit of the installation, but also ensure the accuracy of the detection data of the ranging probe 7.

[0053] Optionally, a second guide plate 30 is fixedly installed on the upper surface of the pallet 28, a second guide rod 31 is connected to one side of the scraper 29, one end of the second guide rod 31 is slidably connected to the second guide plate 30, a third spring 32 is connected between the scraper 29 and the second guide plate 30, the third spring 32 is sleeved on the surface of the second guide rod 31, and an air hole 35 is opened in the scraper 29.

[0054] In this embodiment, for example, two parallel second guide plates 30 are bolted to the upper surface of the support plate 28, forming a 15mm wide guide channel between the guide plates. One end of the second guide rod 31 is welded to the mounting base of the scraper 29, and the other end passes through the linear bearing of the second guide plate 30, forming a horizontal sliding guide. A third spring 32 is sleeved on the outside of the second guide rod 31. When the scraper 29 contacts the surface of the crossbeam to be installed, the spring is compressed to generate contact pressure, allowing the scraper 29 to adapt to the slight undulations of the crossbeam surface and ensure full contact. The scraper 29 is machined into a cutting edge structure with an inclination of 30°-40°, which can effectively scrape off dust, oil stains, and floating rust on the surface of embedded parts.

[0055] Example 4

[0056] This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1 to 9 The top of the movable upright plate 1 has a groove 41, and a drive assembly is installed in the groove 41. The drive assembly includes a rotating shaft 38 that rotates through the groove 41. A fan wheel 40 is fixedly installed at one end of the rotating shaft 38. A gear 39 is fixedly installed on the surface of the rotating shaft 38. A rack 37 is connected to one side of the support plate 9, and the rack 37 and the gear 39 mesh. The fan wheel 40 is driven to one side of the drive assembly. The fan wheel 40 is rotatably connected to the movable upright plate 1, and the fan wheel 40 is located near the scraping assembly.

[0057] In this embodiment, for example, the rotating shaft 38 is mounted in the bearing seat of the movable vertical plate 1 via two deep groove ball bearings. A fan wheel 40 is mounted on the protruding portion near the scraper 29, with a gear 39 installed in its middle section. The gear 39 is fixed to the rotating shaft 38 via a key connection. A rack 37 matches the gear 39 and is fixed to the side of the support plate 9 with countersunk screws. The tooth surface is heat-treated to improve wear resistance. When the first electric slide 2 drives the movable plate 3 and the support plate 9 to move, the rack 37 moves synchronously. The meshing transmission between the gear 39 and the rack 37 drives the rotating shaft 38 to rotate, thereby driving the fan wheel 40 to rotate and generate airflow. The airflow generated by the fan wheel 40 meets the airflow injection requirements of the air hole 35, allowing the airflow to be smoothly blown to the inclined area of ​​the scraper 29, cleaning away the deposited scraped material. Meanwhile, the structure utilizes the moving power of the ranging component to drive the wind turbine 40, eliminating the need for an additional drive motor, simplifying the device structure, reducing energy consumption, and achieving linkage control between cleaning and measurement actions. When the ranging component moves to the measurement position, the wind turbine 40 synchronously generates airflow to clean the measurement area, ensuring the cleanliness of the measurement environment.

[0058] Optionally, the air holes 35 are evenly distributed along the length of the scraper 29. The inlet end of the air holes 35 forms an airflow trajectory with the air outlet of the impeller 40 through a flexible hose. When the impeller 40 rotates and generates airflow, the high-speed airflow is ejected through the air holes 35, forming an airflow barrier on the cleaned surface of the scraper 29, blowing away residual fine particles, improving the efficiency of removing stains, and avoiding secondary pollution.

[0059] Optionally, the outlet end of the air vent 35 is machined with a flat cut to allow the airflow to diffuse in a fan shape, thereby expanding the cleaning area.
