Description

Technical Field

[0001] This utility model relates to the field of single-piece testing technology for standard sections, and more specifically, to a dedicated testing device for single-piece standard sections of tower cranes. Background Technology

[0002] Tower cranes are crucial lifting equipment in engineering construction, and their safety performance directly affects construction safety and project progress. The standard section structure is the mainstream structural form of tower crane towers, consisting of multiple individual sections connected on-site via pins. Each standard section typically consists of two main chords, multiple connecting plates, step plates, node plates, web members, etc., welded together. The structure is complex with dense welds. Each section is the basic unit for assembling the standard section, and its precision directly determines the final connection quality, load-bearing capacity, and overall verticality of the standard section. Therefore, it is necessary to inspect each individual section of the tower crane's standard section.

[0003] Current inspection methods mainly rely on general measuring tools, such as rulers, tape measures, squares, levels, vernier calipers, etc., to measure each item one by one. This is extremely inefficient, and the accuracy is greatly affected by human factors. The inspection process lacks stable clamping. Laser scanning inspection is easily affected by dust on the workpiece surface, which affects the final inspection accuracy. In view of this, this utility model proposes a special inspection device for single standard sections of tower cranes. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a special detection device for a single section of the standard tower crane section, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dedicated testing device for single standard tower crane sections, comprising a testing platform. A positioning and clamping structure for clamping single standard tower crane sections is installed on the testing platform. Support plates are fixedly installed on both sides of the top of the testing platform. A lead screw and a sliding rod are arranged between the two support plates. The lead screw is located on one side of the sliding rod, and a servo motor is installed at one end of the lead screw. A movable seat is installed on the outside of both the lead screw and the sliding rod. The servo motor is fixedly installed on the outer wall of the corresponding support plate, and its output end is fixedly connected to the lead screw. The lead screw is rotatably connected between the two support plates. The sliding rod is fixed between the two support plates. The movable seat is threadedly connected to the lead screw and the sliding rod, and slidably connected to both. A mounting plate is provided at the bottom of the movable seat. Several connecting rods are fixedly installed between the movable platform and the mounting plate. A three-dimensional laser scanner is fixedly installed on one side of the bottom of the mounting plate. A purging structure is provided at the bottom of the mounting plate and on the side of the three-dimensional laser scanner.

[0006] As can be seen, this structure fixes the standard section of the single piece through a positioning clamping structure, and uses a servo motor to drive the moving seat to move the blowing structure and the three-dimensional laser scanner along the lead screw and slide bar to achieve cleaning and dimensional detection of the single piece.

[0007] Preferably, the purging structure includes an air collecting head, which is disposed at the bottom of the mounting plate and located on one side of the 3D laser scanner. The bottom of the air collecting head is connected to several high-pressure nozzles. A first electric push rod is mounted on the mounting plate, and an air pump is mounted on the movable base. The air outlet of the air pump is connected to an air delivery hose. The output end of the first electric push rod is connected to the air collecting head, and one end of the air delivery hose is connected to the air collecting head.

[0008] In order to adjust the height of the air collecting head by means of the first electric push rod, and to supply air to the air collecting head through the air pump via the air supply hose, and then to spray high-pressure airflow from the high-pressure nozzle to achieve the blowing and cleaning of the surface of a single piece of standard section.

[0009] Preferably, the positioning and clamping structure includes a positioning plate, which is fixedly installed on the testing table. A clamping plate is provided on one side of the positioning plate. A support seat is fixedly installed at the center of the surface of the testing table. A second electric push rod is fixedly installed on the support seat, and the output end of the second electric push rod is fixedly connected to the clamping plate. The clamping plate is slidably connected on the testing table. Several anti-slip rubber protrusions are fixedly installed on the outer walls of both the clamping plate and the positioning plate. Connecting seats are fixedly installed on the outer walls of the testing table and on both sides of the support seat. Guide rods are slidably installed on the connecting seats, and one end of the guide rods is fixedly connected to the clamping plate.

[0010] In order to achieve stable clamping by means of the fixed positioning plate and the clamping plate driven by the second electric push rod, the guide rod slides on the connecting seat to achieve stable clamping. At the same time, the anti-slip rubber protrusions enhance the anti-slip effect and reduce the wear of the standard section piece, thereby stabilizing the workpiece to be tested.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a purging structure, the height of the air collecting head can be adjusted using the first electric push rod before testing, so that the high-pressure nozzle is aligned with the standard section piece. The air pump delivers airflow through the air delivery hose and sprays it out from the high-pressure nozzle. At the same time, it moves laterally with the moving base to achieve comprehensive purging, effectively removing surface dust and avoiding interference from dust on the detection accuracy of the 3D laser scanner, thus ensuring the accuracy of the test results. 2. By driving the lead screw to rotate between the two support plates via a servo motor, the moving seat can move laterally along the slide bar in a stable manner. This allows the purging structure at the bottom of the mounting plate and the 3D laser scanner to move laterally on the top of the standard section piece. This not only ensures thorough purging and cleaning but also makes the 3D laser scanning inspection comprehensive and complete, thus improving the effectiveness of the device. 3. By placing a single standard tower crane section on the testing table and closely abutting it against the surface of the positioning plate, initial positioning is achieved. Combined with the second electric push rod driving the clamping plate to slide, a stable clamping can be formed between the positioning plate and the clamping plate. The guide rod ensures a smooth clamping process, and the anti-slip rubber protrusions enhance anti-slip properties and reduce wear, effectively preventing workpiece displacement during testing. This provides a stable benchmark for subsequent purging and scanning inspections, ensuring the reliability of the testing process. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-5The tower crane standard section single-piece special testing device shown includes a testing platform 1. The testing platform 1 is equipped with a positioning and clamping structure for clamping the single-piece tower crane standard section. Support plates 2 are fixedly installed on both sides of the top of the testing platform 1. A lead screw 3 and a slide rod 4 are arranged between the two support plates 2. The lead screw 3 is located on one side of the slide rod 4. A servo motor 5 is installed at one end of the lead screw 3. A movable seat 6 is installed on the outside of the lead screw 3 and the slide rod 4. The servo motor 5 is fixedly installed on the outer wall of the corresponding support plate 2, and the output end of the servo motor 5 is fixedly connected to the lead screw 3. The lead screw 3 is rotatably connected between the two support plates 2. The slide rod 4 is fixed between the two support plates 2. The movable seat 6 is threadedly connected to the lead screw 3 and the slide rod 4 respectively. A mounting plate 7 is provided at the bottom of the movable seat 6. Several connecting rods 8 are fixedly installed between the movable seat 6 and the mounting plate 7. A three-dimensional laser scanner 9 is fixedly installed on one side of the bottom of the mounting plate 7. A purging structure is provided at the bottom of the mounting plate 7 and on one side of the three-dimensional laser scanner 9.

[0020] Specifically, in this structure, a single standard tower crane section can be placed on the inspection table 1 and positioned and clamped by a positioning and clamping structure. During inspection, the servo motor 5 drives the lead screw 3 to rotate between two support plates 2, causing the moving seat 6 to move laterally under the action of the slide rod 4. Then, through several connecting rods 8, the mounting plate 7 is moved, causing the blowing structure and the 3D laser scanner 9 to move above the single standard tower crane section. The blowing structure is first used to blow away the dust on the surface of the single standard tower crane section to prevent the dust from affecting subsequent inspections. The 3D laser scanner 9 is used to perform dimensional inspection on the single standard tower crane section. The 3D laser scanner 9 is existing equipment and will not be described in detail.

[0021] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figure 3, the purging structure includes an air collecting head 10, which is located at the bottom of the mounting plate 7 and on one side of the 3D laser scanner 9. Several high-pressure nozzles 11 are connected to the bottom of the air collecting head 10. A first electric push rod 12 is mounted on the mounting plate 7, and an air pump 13 is mounted on the movable seat 6. The air outlet of the air pump 13 is connected to an air delivery hose 14. The output end of the first electric push rod 12 is connected to the air collecting head 10, and one end of the air delivery hose 14 is connected to the air collecting head 10.

[0022] Specifically, in this structure, before the dimensional inspection of a single section of the tower crane's standard segment, the first electric push rod 12 can drive the air collecting head 10 to extend downwards, so that several high-pressure nozzles 11 are located directly above the single section of the tower crane's standard segment. At this time, the air pump 13 generates airflow, which is delivered to the interior of the air collecting head 10 through the air delivery hose 14, and finally sprayed out through several high-pressure nozzles 11. The sprayed high-pressure airflow can blow away and clean the dust on the surface of the single section of the tower crane's standard segment, so as to avoid affecting the subsequent inspection operation of the single section of the tower crane's standard segment. At the same time, with the movement of the movable base 6, the dust on the surface of a single piece of the tower crane's standard section can be evenly blown away. The air supply hose 14 has a certain length and does not affect the up and down movement of the air collecting head 10.

[0023] In this embodiment, as shown in the appendix Figure 1 , 4 As shown in Figure 5, the positioning and clamping structure includes a positioning plate 15, which is fixedly installed on the testing table 1. A clamping plate 16 is provided on one side of the positioning plate 15. A support seat 17 is fixedly installed at the center of the surface of the testing table 1. A second electric push rod 18 is fixedly installed on the support seat 17, and the output end of the second electric push rod 18 is fixedly connected to the clamping plate 16. The clamping plate 16 is slidably connected on the testing table 1. Several anti-slip rubber protrusions 19 are fixedly installed on the outer walls of both the clamping plate 16 and the positioning plate 15. Connecting seats 20 are fixedly installed on the outer walls of the testing table 1 and on both sides of the support seat 17. A guide rod 21 is slidably installed on the connecting seat 20, and one end of the guide rod 21 is fixedly connected to the clamping plate 16.

[0024] Specifically, in this structure, when positioning and clamping a single piece of the tower crane standard section, the single piece of the tower crane standard section is placed on the testing table 1 and close to the surface of the positioning plate 15 to achieve initial positioning. Then, the second electric push rod 18 on the support base 17 drives the clamping plate 16 to slide on the testing table 1 and move closer to the positioning plate 15. The clamping plate 16 can be guided by sliding on the connecting seat 20 through the guide rod 21, so that the single piece of the tower crane standard section is positioned and clamped between the clamping plate 16 and the positioning plate 15, avoiding displacement during testing. When a single standard section of the tower crane is positioned and clamped between the clamping plate 16 and the positioning plate 15, several anti-slip rubber protrusions 19 fixedly installed on the outer walls of the clamping plate 16 and the positioning plate 15 can improve the clamping and anti-slip effect of the single standard section of the tower crane and reduce wear on its surface.

[0025] Working principle of this utility model: This application provides a dedicated testing device for single standard sections of tower cranes. In practical use, the single standard section of the tower crane is first placed on the testing platform 1, so that it is close to and fits against the surface of the positioning plate 15 to complete the initial positioning. Then, the second electric push rod 18 on the support base 17 is activated, which drives the clamping plate 16 to slide along the testing platform 1 towards the positioning plate 15. During this process, the clamping plate 16 slides on the connecting seat 20 through the guide rod 21 to achieve stable guidance. Finally, the single standard section is firmly clamped between the positioning plate 15 and the clamping plate 16. At the same time, the anti-slip rubber protrusions 19 on the outer walls of both not only enhance the anti-slip effect of clamping, but also reduce the wear on the surface of the single standard section and prevent displacement during testing. Before dimensional inspection, the first electric push rod 12 on the mounting plate 7 drives the air collecting head 10 to extend downward, so that several high-pressure nozzles 11 are directly above the standard section piece. Then, the air pump 13 on the moving seat 6 generates airflow, which is delivered to the inside of the air collecting head 10 through the air supply hose 14. The high-pressure airflow is then sprayed out through the high-pressure nozzles 11. In conjunction with the servo motor 5 driving the lead screw 3 to rotate, the moving seat 6 moves laterally along the slide bar 4, thereby making the air collecting head 10 move synchronously with the mounting plate 7, so as to achieve uniform blowing of dust on the surface of the standard section piece and avoid dust interference with subsequent inspection. The sufficient length of the air supply hose 14 can meet the vertical movement requirements of the air collecting head 10. After the purging is completed, the servo motor 5 continues to drive the lead screw 3 to rotate. The moving seat 6, carrying the mounting plate 7 and the 3D laser scanner 9 at the bottom, moves laterally along the slide bar 4. During the movement, the 3D laser scanner 9 performs a full scan on the cleaned and stably clamped tower crane standard section, thereby completing the dimensional inspection operation.
