Description

Technical Field

[0001] The present invention relates to the technical field of standard section quality detection, in particular to a standard section quality detection device. Background Art

[0002] In the existing elevator master section quality inspection process, the master section is typically hoisted onto a fixed bracket using a crane. A professional then manually adjusts the master section's position so that its main chord aligns with the locating sleeve on the positioning device. This step requires the operator to possess considerable experience and skill to ensure precise alignment of the master section. Once the main chord is aligned with the locating sleeve, a pneumatic cylinder is activated to automatically extend the locating sleeve until it is fully inserted into the main chord, firmly positioning the master section. After the master section is securely positioned, a high-brightness searchlight illuminates the master section's weld, and a high-resolution camera records the weld image for subsequent analysis.

[0033] Example 1

[0034] Reference Figures 1 and 2 , which is the first embodiment of the present invention, provides a standard section quality detection device, including a fixing unit 100, including two sets of vertical plates 101, multiple sets of connecting members 102 arranged inside the vertical plates 101, positioning members 103 arranged inside the connecting members 102, and cylinders 104 arranged outside the positioning members 103;

[0035] The rotating unit 200 includes a rotating member 201 disposed outside the vertical plate 101, a bearing 202 disposed outside the rotating member 201, a support platform 203 disposed at the bottom of the bearing 202, and a base 204 disposed at the bottom of the support platform 203;

[0036] The positioning member 103 can first position the standard section and then fix it.

[0037] Furthermore, the searchlight unit 300 includes a stand 301 arranged parallel to one side of the fixing unit 100, and a searchlight 302 arranged on the stand 301;

[0038] The detection unit 400 includes a camera 401 arranged parallel to one side of the searchlight 302 and a column 402 arranged at the bottom of the camera 401 .

[0039] Furthermore, each set of vertical plates 101 includes a reinforcing rib 101a provided on the back side thereof, a through hole 101b penetrating the middle thereof, a sleeve 101c provided at the four corners of the end surface thereof, and a receiving tube 101d provided on one side of the sleeve 101c.

[0040] Furthermore, the connecting member 102 includes a screw rod 102 a disposed inside the sleeve 101 c , a nut 102 b disposed outside the screw rod 102 a , and a blocking rod 102 c disposed between the two sets of vertical plates 101 .

[0041] Furthermore, the rotating member 201 includes a cone 201a connected to the through hole 101b, and a rotating shaft 201b arranged outside the cone 201a.

[0042] It should be noted that the fixing unit 100 consists of two sets of vertical plates 101, connectors 102 at the four corners of the two sets of vertical plates 101, positioning members 103, and a cylinder on the rear side of the vertical plates 101. The connectors 102 are used to clamp the standard section. The positioning members 103 are used to position and secure the standard section. The positioning members 103 are connected to the cylinder 104, which is used to push the positioning members 103 to extend and retract, thereby firmly securing the standard section.

[0043] Preferably, the vertical plate 101 can be a steel plate. A reinforcing rib 101a is welded on the back of the vertical plate 101 to strengthen the bearing rigidity of the vertical plate 101. A through hole 101b is provided in the middle of the vertical plate 101, and the through hole 101b can be connected to the rotating member 201. In addition, sleeves 101c are provided at the four corners of the vertical plate 101, and the sleeves 101c can connect the two groups of vertical plates 101 together with the through-connecting member 102. Similarly, a receiving tube 101d is provided at the corners of the vertical plate 101 and on the inner side of the sleeve 101c, and the receiving tube 101d allows the positioning member 103 to position and fix the main chord Q in the standard section.

[0044] Preferably, the connector 102 tightly connects the two sets of risers 101. A set of screws 102a extends through the sleeves 101c corresponding to the two sets of risers 101, and a set of bars 102c is connected between the risers 101. The screws 102a extend inside the bars 102c and are connected to the back of the risers 101 using nuts 102b. The bars 102c securely connect the two sets of risers 101 at equal intervals.

[0045] Preferably, there are two groups of rotating units 200, which are symmetrically arranged on the outside of each group of vertical plates 101. The rotating member 201 can allow the standard section to rotate during the inspection process, facilitating all-round inspection. A bearing 202 is provided on the outside of the rotating member 201 to provide rotation support. The bottom of the bearing 202 is bolted to the support platform 203, which is used to support the entire rotating mechanism. A base 204 is provided at the bottom of the support platform 203 to ensure the stability of the rotating unit. The base 204 is a patterned steel plate, which can increase the friction of the surface.

[0046] Preferably, the rotating member 201 comprises a cone 201a and a rotating shaft 201b outside the cone 201a. The cone 201a is bolted to the through hole 101b of the vertical plate 101. The rotating shaft 201b at the rear of the cone is mounted on the inside of a bearing 202 and can be rotated by an external drive device.

[0047] Preferably, the positioning member 103 first positions the standard section and then fixes it to ensure the stability and positioning accuracy of the standard section during the inspection process. The searchlight unit 300 includes a stand 301 arranged parallel to one side of the fixing unit 100, and the stand is used to install a searchlight. The searchlight 302 arranged on the stand 301 is used to illuminate the weld area of ​​the standard section to facilitate the camera to capture clear images. The inspection unit 400 includes a camera 401 arranged parallel to one side of the searchlight 302, which is used to take high-definition images of the standard section weld. A column 402 is provided at the bottom of the camera 401 to ensure that the camera position is stable and obtain high-quality inspection images.

[0048] During use, a crane is used to lift the standard section above the fixed unit 100 and slowly lower it. Once inside the fixed unit 100, the standard section is positioned between the two sets of vertical plates 101. The four sets of stop bars 102c on the upper and lower sides of the vertical plates 101 do not restrict the lifted standard section from entering the interior of the vertical plates 101. Once the standard section enters the interior of the vertical plates 101, the cylinder 104 pushes the positioning member 103 to first position the four main chords Q of the standard section. The cylinder 104 then drives the positioning member 103 back, whereupon the positioning member 103 penetrates both ends of the standard section to secure it in the correct position. After the standard section is secured, the rotating member 201 and bearing 202 of the rotating unit 200 are used to rotate the standard section to the desired angle. The searchlight 302 is activated to illuminate the weld area of ​​the standard section. The camera 401 captures high-definition images of the standard section weld for subsequent analysis. The captured images are transmitted to the analysis system to assess whether the weld quality meets established standards.

[0049] Through the coordinated work of the fixing unit 100, the rotating unit 200, the searchlight unit 300 and the detection unit 400, this device achieves precise positioning of the standard section, all-round detection and high-quality image acquisition, thereby ensuring that the welding quality of the elevator standard section meets the standard requirements.

[0050] Example 2

[0051] Reference Figures 2 to 6 , which is the second embodiment of the present invention, is different from the first embodiment in that: it includes a positioning member 103 including a positioning rod 103a arranged on the inner side of the accommodating tube 101d, a driving member 103b arranged at the bottom of the positioning rod 103a, a frame rod 103c arranged at the bottom of the driving member 103b, and a support frame 103d at the bottom of the frame rod 103c.

[0052] Furthermore, the positioning rod 103a is movably connected to the interior of the accommodating tube 101d and can be inserted into the tube of the main chord Q;

[0053] One side of the frame rod 103 c is fixedly connected to the piston rod 104 a of the cylinder 104 .

[0054] Furthermore, the rack 103c includes a V-shaped rack 103c-1 that can be mounted on the outside of the main chord Q, and a slide plate 103c-2 that is arranged on the rear side of the V-shaped rack 103c-1;

[0055] The end surface of the slide plate 103c-2 is provided with a sliding groove 103c-21 and a connecting rod 103c-22 arranged inside the sliding groove 103c-21.

[0056] Furthermore, the driving member 103b includes a rotating frame 103b-1 provided on the end surface of the supporting frame 103d, and a rotating rod 103b-2 provided on the rotating frame 103b-1;

[0057] Circular grooves 103b-21 are provided through both ends of the rotating rod 103b-2.

[0058] Furthermore, a connecting cap 103a-1 is provided at the bottom of the positioning rod 103a, and an avoidance groove 103a-2 is opened at the bottom of the positioning rod 103a.

[0059] It should be noted that, as can be seen from the first embodiment, receiving tubes 101d are provided through the corners of the risers 101, and these receiving tubes 101d are located inside sleeves 101c also provided through the corners of the risers 101. Therefore, when the receiving tubes 101d are used to erect the main chord Q of the standard section, the connection function of the outer blocking rods 102c will not be hindered.

[0060] Preferably, a set of positioning rods 103a is slidably mounted on the inner side of each set of receiving tubes 101d. The positioning rods 103a slide back and forth within the receiving tubes 101d to secure the main chord Q of the standard section. The positioning rods 103a have a narrow end at one end, which facilitates insertion into the tube of the main chord Q. The rear end of the positioning rods 103a is a wide end. The narrow end of the positioning rods 103a is tapered to facilitate insertion into the tube of the main chord Q, while the wide end acts as a limiter, preventing the positioning rods 103a from falling out of the receiving tubes 101d during operation. This design ensures that the positioning rods 103a can be stably inserted into the main chord Q during use, thereby achieving precise fixation of the standard section.

[0061] Preferably, the positioning rod 103a is connected to the mounting rod 103c via the driving member 103b. The mounting rod 103c is used to position the standard component that is hoisted and placed inside the vertical plate 101, thereby reducing human intervention and avoiding the need for manual alignment of the main chord Q during the fixing process of the standard component.

[0062] Preferably, the support rod 103c is supported by a support frame 103d welded to the front end of the riser 101 at a designated location on the riser 101, securing the main chord Q. The support rod 103c comprises a V-shaped frame 103c-1 for securing the main chord Q, and a slide plate 103c-2 at the rear end of the V-shaped frame 103c-1. The V-shaped frame 103c-1 is shaped like a V with an outward opening, allowing it to better accommodate the position of different standard main chords Q being lifted and lowered, securing them in a designated spatial location. The slide plate 103c-2, bolted to the rear end of the V-shaped frame 103c-1, can slide back and forth on the end surface of the support frame 103d, thereby driving the V-shaped frame 103c-1 back and forth, achieving the positioning function of the V-shaped frame 103c-1 and then transitioning to the limiting function of the positioning rod 103a. Support frame 103d is equipped with a retaining groove to limit the forward and backward movement of slide plate 103c-2. Driven by cylinder 104, slide plate 103c-2 controls the forward and backward movement of V-shaped frame 103c-1, ensuring the stability of frame rod 103c during the sliding process. The design of V-shaped frame 103c-1 effectively supports the main chord Q of the standard joint, preventing it from shifting during positioning.

[0063] Preferably, the positioning rod 103a is connected to the frame rod 103c through a driving member 103b. The driving member 103b includes a rotating frame 103b-1 disposed on the end surface of the support frame 103d, and a rotating rod 103b-2 disposed on the rotating frame 103b-1. Circular grooves 103b-21 are provided at both ends of the rotating rod 103b-2. A set of connecting rods 103c-22 are sleeved within the circular grooves 103b-21 below. This ensures that when the piston rod 104a at the front end of the cylinder 104 drives the slide 103c-2 to move forward, the connecting action of the connecting rods 103c-22 and the circular grooves 103b-21 enables the rotating rod 103b-2 to follow the rotation of the slide 103c-2. The design of the rotating frame 103b-1 allows the rotating rod 103b-2 to rotate smoothly, thereby driving the positioning rod 103a to move along the direction of the accommodating cylinder 101d. The circular groove 103b-21 of the rotating rod 103b-2 provides traction, ensuring that when the slide plate 103c-2 is subjected to a forward or backward force, the rotating rod 103b-2 is driven to rotate through the connection of the groove rod.

[0064] Preferably, a sliding groove 103c-21 is defined on the upper end surface of the slide plate 103c-2, and a connecting rod 103c-22 is disposed within the sliding groove 103c-21. This connecting rod 103c-22 is sleeved within the inner side of the rotating rod 103b-2. The positioning rod 103a is connected to the frame rod 103c via a driving member 103b. The driving member 103b comprises a rotating frame 103b-1 disposed on the end surface of the support frame 103d, and a rotating rod 103b-2 disposed on the rotating frame 103b-1. Both ends of the rotating rod 103b-2 are provided with circular grooves 103b-21. A set of connecting rods 103c-22 are sleeved within the lower circular grooves 103b-21. This ensures that when the piston rod 104a at the front end of the cylinder 104 drives the slide 103c-2 forward, the connecting rods 103c-22 and the circular grooves 103b-21 connect, allowing the rotating rod 103b-2 to follow the rotation of the slide 103c-2. The bottom of the positioning rod 103a is provided with a connecting cap 103a-1 for connecting with the other set of circular grooves 103b-21 above. The bottom of the positioning rod 103a also has an avoidance groove 103a-2, ensuring that the positioning rod 103a can smoothly extend and retract during the rotation of the rotating rod 103b-2.

[0065] Preferably, the design of the rotating frame 103b-1 allows the rotating rod 103b-2 to rotate smoothly, thereby driving the positioning rod 103a to move along the direction of the accommodating tube 101d. The circular groove 103b-21 of the rotating rod 103b-2 provides a traction effect, ensuring that when the slide plate 103c-2 is subjected to a forward or backward force, the connecting action of the groove rod drives the rotating rod 103b-2 to rotate, thereby achieving the positioning effect of first positioning the frame mouth of the V-shaped frame 103c-1 on the outside of the main chord Q, adjusting it from its original offset position to a position consistent with the horizontal position of the positioning rod 103a; then the V-shaped frame 103c-1 retracts to pull the positioning rod 103a out and insert it into the main chord Q tube to achieve the limiting effect.

[0066] Preferably, the center of rotating rod 103b-2 does not extend through the axis of rotating frame 103b-1, but rather is positioned above rotating frame 103b-1, creating an eccentric effect. When the circular groove 103b-21 below moves with connecting rod 103c-22, the circular groove 103b-21 above it and the connecting cap 103a-1 rotate, causing the displacement of positioning rod 103a to become more pronounced, ensuring a more effective connection with the main chord Q.

[0067] During the inspection process, the standard section is steadily lifted to the top of the fixing unit 100 by a crane and slowly lowered. At this time, the standard section is placed in the center of the fixing unit 100 and is ready for positioning and fixing.

[0068] First, cylinder 104 drives piston rod 104a to push slide 103c-2, pushing out rack rod 103c. This action, through the extension of piston rod 104a in cylinder 104, pushes slide 103c-2 outward along sliding slot 103c-21, pushing rack rod 103c to the desired position. Simultaneously, this action retracts positioning rod 103a, which was moved out during the previous inspection, back to its original position, ensuring that all components are reset.

[0069] Next, the V-shaped bracket 103c-1 within the bracket 103c performs preliminary positioning of the master section. The design of the V-shaped bracket 103c-1 effectively supports the master section's main chord Q, preventing it from shifting during positioning. This preliminary positioning step reduces manual intervention and eliminates the need for manual alignment of the main chord Q during the master section's fixture process, thereby improving inspection consistency and accuracy.

[0070] Then, cylinder 104 is activated again, and its piston rod 104a begins to retract rack rod 103c. During this retraction process, connecting rod 103c-22 inside slide 103c-2 pulls rotating rod 103b-2 in rotation. Specifically, driven by slide 103c-2, connecting rod 103c-2 engages within circular groove 103b-21, causing rotating rod 103b-2 to rotate. This rotation is achieved through the articulation of rotating rack 103b-1, ensuring smooth rotation of rotating rod 103b-2.

[0071] As rotating rod 103b-2 rotates, the circular groove 103b-21 above pulls the connecting cap 103a-1, thereby driving the positioning rod 103a forward along the receiving tube 101d. The narrow end of the positioning rod 103a is designed to be tapered to facilitate insertion into the tube of the main chord Q. This continuous movement ensures that the positioning rod 103a is accurately inserted into the tube of the main chord Q, firmly securing the standard section, and then completely releasing the lifting rope.

[0072] The extension and retraction of positioning rod 103a is driven entirely by piston rod 104a of cylinder 104, ensuring the stability and precise alignment of the master joint during testing. The design of positioning rod 103a ensures that it can smoothly enter and exit the tube of main chord Q during extension and retraction, thereby achieving a stable fixation effect.

[0073] In summary, during the quality inspection of elevator standard sections, this technology uses a V-shaped frame to perform preliminary positioning of the standard section, ensuring that the main chord can be accurately aligned with the positioning sleeve to achieve precise alignment. Then, by accurately inserting the positioning rod into the tube of the main chord, it is firmly fixed, thereby significantly improving the accuracy and stability of the inspection. The automated positioning and fixing mechanism not only eliminates the uncertainty brought about by the need for manual adjustment of alignment in traditional methods, reduces operational errors, but also improves the consistency and reliability of inspection, while significantly reducing the workload of operators. In addition, the positioning and fixing process can be completed quickly and accurately, reducing the time for manual adjustment, improving inspection efficiency, and reducing safety hazards caused by improper manual operation, thereby enhancing the safety and reliability of the inspection process.

[0074] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
