Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to an automatic assembly and positioning method for L-shaped rib plate units and apple-shaped open diaphragms. Background Technology

[0002] To improve the fatigue resistance of the bridge deck system, several apple-shaped openings are made on the transverse diaphragm to form channels through which the L-shaped ribs of the L-shaped rib plate unit pass. After the L-shaped ribs of the L-shaped rib plate unit pass through the corresponding apple-shaped openings of the transverse diaphragm, the assembly gap between the transverse diaphragm and the L-shaped stiffening rib is required to be no greater than 2.0 mm. Since the L-shaped rib plate unit is assembled with the diaphragm, it cannot fall directly into the slot above the diaphragm like the traditional U-ribs and I-ribs. It can only be pushed in by translating from one side and the other side of the L-shaped rib. The L-shaped rib plate unit is 16 m long and has 13 L-ribs. The maximum pushing distance of the transverse diaphragm is 7 m.

[0003] Chinese invention patent CN118375062A discloses a method for assembling an L-shaped rib plate unit and a transverse partition plate with a small gap by pushing them together. By setting a U-shaped magnetic suction unit on the surface of the partition plate and placing it between adjacent L-shaped rib plate units, and then driving it together with two sets of traction hydraulic cylinders, the partition plate can be ensured to slide synchronously at all positions. Furthermore, a 0.1mm thick sheet metal structure is set on both sides of the L-shaped rib plate unit and coated with grease to isolate the contact position between the partition plate and the L-shaped rib plate unit, thereby reducing the friction between the partition plate and the L-shaped rib plate unit.

[0004] In practice, the above assembly method requires marking lines on the L-shaped ribs of the L-shaped rib unit beforehand to indicate the assembly positions of each diaphragm. When the traction hydraulic cylinder moves the diaphragm, the movement position of the diaphragm needs to be observed visually. When the diaphragm moves close to the assembly position, the movement amplitude of the traction hydraulic cylinder is manually controlled. The position of the diaphragm is repeatedly adjusted based on the marked assembly position line. This process is not only cumbersome and time-consuming, but also has low positioning accuracy. In addition, the traction hydraulic cylinder is fixed on the surface of the L-shaped rib unit. When a diaphragm moves into place, it will block the traction hydraulic cylinder, preventing it from smoothly connecting to the diaphragm behind it. Therefore, after the diaphragm moves into place, the traction hydraulic cylinder needs to be manually removed and then installed behind the front diaphragm to connect with and move the next diaphragm. Each removal and installation of the traction hydraulic cylinder requires recalibration, which is not only cumbersome and labor-intensive, but also has an adverse effect on the positioning accuracy of subsequent diaphragm movements.

[0005] Therefore, this invention proposes an automatic assembly and positioning method for L-shaped rib plate units and apple-shaped open diaphragms to solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automatic assembly and positioning method for L-shaped rib plate units and apple-shaped open diaphragms, which adopts an automated measurement and positioning and continuous traction linkage mechanism to achieve high-precision continuous automated assembly of diaphragms.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic assembly and positioning method for L-shaped rib plate units and apple-shaped open transverse partitions. The innovation of this method is that the automatic assembly and positioning method is completed by the cooperation of a traction beam and a traction fixture. The traction fixture includes a traction hydraulic cylinder and a crossing support mechanism. The traction hydraulic cylinder is installed on the top of the crossing support mechanism. The traction beam is connected to the front end of the telescopic rod of the traction hydraulic cylinder. The traction beam has a first electromagnet for energizing and adsorbing the transverse partition. The bottom of the crossing support mechanism has a second electromagnet for energizing and adsorbing the L-shaped rib plate units.

[0008] The automatic assembly and positioning method includes the following steps:

[0009] Step 1, Equipment Installation and Baseline Positioning: Place the L-shaped rib plate unit on the support frame, and install the base plate on the support frame according to the process requirements. Place the traction fixture at the designated position on the L-shaped rib plate unit, ensuring that the central axis of the traction hydraulic cylinder is parallel to the extension direction of the L-shaped rib plate of the L-shaped rib plate unit. Then, energize the second electromagnet to fix the traction fixture.

[0010] Step 2, Diaphragm Traction: Using a distance sensor and a reference plate, determine the required assembly position of the diaphragm to be assembled and the distance between it and the traction fixture at this time. Then, the telescopic rod of the traction hydraulic cylinder moves, pushing the traction beam forward to the pre-set crossbeam on the L-shaped rib unit to be assembled. After the first electromagnet is energized and attracts the crossbeam to be assembled, the traction beam moves backward, causing the crossbeam to move along the L-shaped rib of the L-shaped rib unit. The distance sensor detects the distance between the crossbeam to be assembled and the traction fixture in real time. ,when When the diaphragm to be assembled moves into place, the telescopic rod of the traction hydraulic cylinder stops moving;

[0011] Step 3, Traction Tool Movement: After the transverse diaphragm is moved into place and assembled and fixed, the first electromagnet is de-energized and the attraction is canceled. The extension rod of the traction hydraulic cylinder moves backward, driving the traction beam away from the assembled and fixed transverse diaphragm. Then, the crossing support mechanism moves, driving the traction hydraulic cylinder and the traction beam to move from the rear side of the assembled and fixed transverse diaphragm, across the top of the assembled and fixed transverse diaphragm, and to the front side of the assembled and fixed transverse diaphragm, completing the traction tool crossing movement.

[0012] Step 4: The diaphragm assembly is complete. Repeat steps 2 and 3 until all the diaphragms on the L-shaped rib unit are assembled and fixed.

[0013] Furthermore, in step 1, when installing the reference plate on the support frame, the bottom edge line of the L-shaped rib plate unit is used as the reference line to determine the installation position of the reference plate on the support frame.

[0014] Furthermore, in step 2, a distance sensor and a reference plate are used to determine the required assembly position of the transverse partition to be assembled and the distance of the traction tool at this time. The method is as follows:

[0015]

[0016] in, To utilize the distance sensor to detect the distance between the traction tool and the reference plate at this moment, The distance between the assembly position of the transverse diaphragm to be assembled on the L-shaped rib unit and the baseline is specified according to the process requirements. This is the distance between the actual installation position of the reference plate on the support frame and the reference line.

[0017] Furthermore, the crossing support mechanism includes a lifting platform, a front support hydraulic cylinder, and a rear support hydraulic cylinder. A distance sensor is installed on the lifting platform, a traction hydraulic cylinder is installed on the top of the lifting platform, and the front support hydraulic cylinder is installed on the bottom of the lifting platform via a guide rail and is pushed by a translation hydraulic cylinder to move horizontally along the guide rail. The extension direction of the guide rail is parallel to the central axis of the traction hydraulic cylinder. The rear support hydraulic cylinder is installed on the bottom of the lifting platform and cooperates with the front support hydraulic cylinder to push the lifting platform to move up and down between the crossing position and the traction position. The crossing position is located above the traction position. A second electromagnet is installed at the bottom of both the front support hydraulic cylinder and the rear support hydraulic cylinder.

[0018] Furthermore, the detailed process of the traversing support mechanism action in step 3 to complete the traversing movement of the traction tool is as follows:

[0019] Step 3.1: The front support hydraulic cylinder and the rear support hydraulic cylinder move synchronously to push the lifting platform up to the crossing position;

[0020] Step 3.2: After the second electromagnet at the bottom of the front support hydraulic cylinder is de-energized, the telescopic rod of the front support hydraulic cylinder retracts, causing the cylinder body of the front support hydraulic cylinder to move upward.

[0021] Step 3.3: Extend the telescopic rod of the translation hydraulic cylinder forward, push the front support hydraulic cylinder to move along the guide rail, and cross over the assembled and fixed transverse partition;

[0022] Step 3.4: The telescopic rod of the front support hydraulic cylinder extends, causing the cylinder body of the front support hydraulic cylinder to move down to the top surface of the bottom plate of the L-shaped rib unit. The second electromagnet at the bottom of the front support hydraulic cylinder is energized and attracted and fixed on the L-shaped rib unit.

[0023] Step 3.5: After the second electromagnet at the bottom of the rear support hydraulic cylinder is de-energized, the telescopic rod of the rear support hydraulic cylinder retracts, causing the cylinder body of the rear support hydraulic cylinder to move upward.

[0024] Step 3.6: The telescopic rod of the translation hydraulic cylinder retracts, and the cylinder body of the translation hydraulic cylinder drives the lifting platform and the rear support hydraulic cylinder to move forward along the guide rail, so that the lifting platform and the rear support hydraulic cylinder pass over the self-assembled and fixed transverse partition.

[0025] Step 3.7: The telescopic rod of the rear support hydraulic cylinder extends, causing the cylinder body of the rear support hydraulic cylinder to move down to the top surface of the bottom plate of the L-shaped rib unit. The second electromagnet at the bottom of the rear support hydraulic cylinder is energized and attracted and fixed on the L-shaped rib unit.

[0026] Step 3.8: The front support hydraulic cylinder and the rear support hydraulic cylinder move synchronously, pulling the lifting platform down to the traction position.

[0027] Furthermore, in step 3.8, before the front support hydraulic cylinder and the rear support hydraulic cylinder operate synchronously, the distance sensor detects and obtains the distance between the traction tooling and the reference plate at this time. .

[0028] Furthermore, the cylinder bodies of the front support hydraulic cylinder and the rear support hydraulic cylinder are each connected to the lifting platform via guide rods. The bottom end of the guide rod is mounted on the cylinder body of the corresponding front support hydraulic cylinder or rear support hydraulic cylinder via a fixed seat. The lifting platform has a through hole corresponding to the guide rod, and a guide sleeve matching the guide rod is installed in the through hole. The guide rod slides through the guide sleeve.

[0029] Furthermore, in step 2, when the traction beam moves forward to the partition plate to be assembled, a pressure sensor is used to detect whether the traction beam is in contact with the partition plate. When the traction beam is in contact with the partition plate, the first electromagnet is energized to attract and connect the partition plate to be assembled.

[0030] Furthermore, the traction hydraulic cylinder, the front support hydraulic cylinder, and the rear support hydraulic cylinder are all telescopic hydraulic cylinders.

[0031] The advantages of this invention are:

[0032] The automatic assembly and positioning method of this invention is completed by the cooperation of a traction beam and a traction fixture. The traction beam and the traction fixture are equipped with a first electromagnet and a second electromagnet to ensure zero relative displacement between the diaphragm and the traction beam, and between the traction fixture and the L-shaped rib unit, thus eliminating cumulative positioning errors. During the traction process of the diaphragm, a closed-loop control system using a distance sensor and a reference plate is used to provide real-time feedback on the deviation between the diaphragm and the target position. When the diaphragm reaches the assembly position, the traction hydraulic cylinder stops its operation in a timely manner based on the feedback data, avoiding manual measurement errors and ensuring the assembly accuracy of the diaphragm. After the diaphragm is assembled, the traction hydraulic cylinder of the traction fixture can automatically flip over to assemble the fixed diaphragm with the help of a crossing support mechanism. After flipping over, the distance sensor is used for repositioning, breaking through the limitation of traditional fixtures requiring disassembly and reassembly. This forms an automated measurement and positioning and continuous traction linkage mechanism, realizing high-precision continuous automated assembly of the diaphragm. Attached Figure Description

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] Example

[0038] This embodiment provides an automatic assembly and positioning method for L-shaped rib plate units and apple-shaped open transverse partitions, wherein, as... Figure 1 As shown, the L-shaped rib unit 2 consists of a base plate 201 and several L-shaped ribs 202 vertically and parallelly assembled on the top surface of the base plate 201. The bottom of the diaphragm 3 has several slots corresponding to each L-shaped rib 202. After each L-shaped rib 202 of the L-shaped rib unit 2 is inserted into the corresponding slot of the diaphragm 3, the diaphragm 3 needs to be automatically pulled to the diaphragm assembly position of the L-shaped rib unit by the cooperation of the traction beam 16 and the traction fixture to complete the assembly and positioning operation.

[0039] like Figure 2As shown, the traction fixture includes a traction hydraulic cylinder 5 and a crossing support mechanism. The crossing support mechanism includes a lifting platform 6, a front support hydraulic cylinder 7, and a rear support hydraulic cylinder 8. A distance sensor 15 is installed on the front side of the lifting platform. The traction hydraulic cylinder 5 is installed on the top of the lifting platform 6. A traction beam 16 is connected to the front end of the telescopic rod of the traction hydraulic cylinder 5. The traction beam 16 has a first electromagnet 17 for energizing and attracting the crossbar 3. The first electromagnet 17 is distributed on the upper and lower sides of the traction beam 16 and is connected to the traction beam 16 through a connecting frame. The traction beam 16 is also equipped with a pressure sensor for detecting whether the traction beam 16 is in contact with the crossbar 3.

[0040] The front support hydraulic cylinder 7 is mounted on the bottom of the lifting platform 6 via a guide rail 10. A slider 11 matching the guide rail 10 is mounted on the bottom of the lifting platform 6. The guide rail 10 and the slider 11 are slidably connected. The extension direction of the guide rail 10 is parallel to the central axis of the traction hydraulic cylinder 5. The guide rail 10 is connected to the top end of the telescopic rod of the front support hydraulic cylinder 7. The front support hydraulic cylinder 7 is pushed by the translation hydraulic cylinder 9 to move horizontally along the guide rail 10. The translation hydraulic cylinder 9 is mounted on the bottom of the lifting platform 6, and the end of the telescopic rod of the translation hydraulic cylinder 9 is connected to the guide rail 10. The rear support hydraulic cylinder 8 is mounted on the bottom of the lifting platform 6. The end of the telescopic rod of the rear support hydraulic cylinder 8 is connected to the lifting platform 6. The rear support hydraulic cylinder 8 cooperates with the front support hydraulic cylinder 7 to push the lifting platform 6 to move up and down between the crossing position and the traction position. The crossing position is above the traction position. The bottom of both the front support hydraulic cylinder 7 and the rear support hydraulic cylinder 8 is equipped with a second electromagnet 18 for electrically adsorbing the L-shaped rib unit.

[0041] In this embodiment, the cylinder bodies of the front support hydraulic cylinder 7 and the rear support hydraulic cylinder 8 are each connected to the lifting platform 6 via guide rods 12. The central axis of the guide rod 12 is vertically set, and the bottom end of the guide rod 12 is installed on the cylinder body of the corresponding front support hydraulic cylinder or rear support hydraulic cylinder via a fixing seat 14. The lifting platform 6 has a through hole corresponding to the guide rod 12, and a guide sleeve 13 matching the guide rod 12 is installed in the through hole. The guide rod 12 slides through the guide sleeve 13 to guide the relative movement between the lifting platform and the cylinder bodies of the front support hydraulic cylinder 7 and the rear support hydraulic cylinder 8.

[0042] In this embodiment, the traction hydraulic cylinder 5, the front support hydraulic cylinder 7, and the rear support hydraulic cylinder 8 are all telescopic hydraulic cylinders, which have a long stroke and compact structure, smooth movement, and small space occupation.

[0043] The automated assembly and positioning method includes the following steps:

[0044] Step 1, Equipment Installation and Reference Positioning: Place the L-shaped rib plate unit 2 on the support frame 1, and install the reference plate 4 on the support frame 1 according to the process requirements. When installing the reference plate 4 on the support frame 1, use the edge line of the bottom plate 201 of the L-shaped rib plate unit 2 as the reference line to determine the installation position of the reference plate 4 on the support frame 1.

[0045] After placing the traction fixture at the designated position on the L-shaped rib unit 2 and ensuring that the central axis of the traction hydraulic cylinder 5 is parallel to the extension direction of the L-shaped rib 202 of the L-shaped rib unit 2, the second electromagnet 18 at the bottom of the front support hydraulic cylinder 7 and the rear support hydraulic cylinder 8 is energized to fix the traction fixture.

[0046] Step 2, diaphragm traction: Using distance sensor 15 and reference plate 4, determine the required assembly position of the diaphragm 3 to be assembled and the distance between it and the traction fixture at this time. Then, the telescopic rod of the traction hydraulic cylinder 5 moves, pushing the traction beam 16 forward to the pre-positioned transverse partition 3 to be assembled at the end of the L-shaped rib unit 2. The pressure sensor detects whether the traction beam 16 has made contact with the transverse partition 3. When the traction beam 16 has made contact with the transverse partition 3, the first electromagnet 17 is energized and attracts the transverse partition 3 to be assembled. Then, the traction beam 16 moves backward, causing the transverse partition 3 to be assembled to move along the L-shaped rib 202 of the L-shaped rib unit 2. The distance sensor 15 detects the distance between the transverse partition 3 to be assembled and the traction fixture in real time. ,when At that time, the cross diaphragm 3 to be assembled moves into place, and the telescopic rod of the traction hydraulic cylinder 5 stops moving.

[0047] Specifically, by using distance sensor 15 and reference plate 4, the required assembly position of the transverse partition to be assembled and the distance of the traction fixture at this time are determined. The method is as follows:

[0048]

[0049] in, To utilize the distance sensor 15 to detect the distance between the traction tool and the reference plate 4 at this time, The distance between the assembly position of the transverse diaphragm to be assembled on the L-shaped rib unit and the baseline is specified according to the process requirements. This is the distance between the actual installation position of the reference plate on the support frame and the reference line;

[0050] The distance between the traction tool and the reference plate 4 is detected by the distance sensor 15 at this time. At that time, for the traction fixture initially placed at the designated position on the L-shaped rib plate unit 2, after the traction fixture is fixed by the second electromagnet, the rear support hydraulic cylinder 8 and the front support hydraulic cylinder 7 cooperate to push the lifting platform 6 to the crossing position, and the distance sensor 15 detects the distance. Afterwards, the lifting platform 6 descends and returns to the traction position; for the traction fixture that has been moved across, the distance... The detection is completed during the movement.

[0051] Step 3, Moving the Traction Fixture: After the transverse diaphragm is moved into place and assembled and fixed, the first electromagnet 17 is de-energized and the attraction is released. The telescopic rod of the traction hydraulic cylinder 5 moves backward, causing the traction beam 16 to move away from the assembled and fixed transverse diaphragm. Then, the crossing support mechanism moves, causing the traction hydraulic cylinder 5 and the traction beam 16 to move from the rear side of the assembled and fixed transverse diaphragm, across the top of the assembled and fixed transverse diaphragm, and to the front side of the assembled and fixed transverse diaphragm, completing the traction fixture crossing movement. The detailed process is as follows:

[0052] Step 3.1: The front support hydraulic cylinder 7 and the rear support hydraulic cylinder 8 move synchronously to push the lifting platform 6 to the crossing position;

[0053] Step 3.2: After the second electromagnet at the bottom of the front support hydraulic cylinder 7 is de-energized, the telescopic rod of the front support hydraulic cylinder 7 retracts, causing the cylinder body of the front support hydraulic cylinder 7 to move upward.

[0054] Step 3.3: The telescopic rod of the translation hydraulic cylinder 9 extends forward, pushing the front support hydraulic cylinder 7 to move along the guide rail 10 and pass over the assembled and fixed transverse partition.

[0055] Step 3.4: The telescopic rod of the front support hydraulic cylinder 7 extends, causing the cylinder body of the front support hydraulic cylinder 7 to move down to the top surface of the bottom plate 201 of the L-shaped rib unit 2. The second electromagnet at the bottom of the front support hydraulic cylinder 7 is energized and attracted and fixed on the bottom plate 201 of the L-shaped rib unit 2.

[0056] Step 3.5: After the second electromagnet 18 at the bottom of the rear support hydraulic cylinder 8 is de-energized, the telescopic rod of the rear support hydraulic cylinder 8 retracts, causing the cylinder body of the rear support hydraulic cylinder 8 to move upward.

[0057] Step 3.6: The telescopic rod of the translation hydraulic cylinder 9 retracts, and the cylinder body of the translation hydraulic cylinder 9 drives the lifting platform 6 and the rear support hydraulic cylinder 8 to move forward along the guide rail, so that the lifting platform 6 and the rear support hydraulic cylinder 9 pass over the self-assembled and fixed transverse partition. The traction hydraulic cylinder 5 installed on the lifting platform 6 and the traction crossbeam 16 connected to the traction hydraulic cylinder 5 pass over synchronously with the lifting platform 6.

[0058] Step 3.7: The telescopic rod of the rear support hydraulic cylinder 8 extends, causing the cylinder body of the rear support hydraulic cylinder 8 to move down to the top surface of the bottom plate 201 of the L-shaped rib unit 2. The second electromagnet 18 at the bottom of the rear support hydraulic cylinder 8 is energized and attracted and fixed on the bottom plate 201 of the L-shaped rib unit 2.

[0059] Step 3.8: Distance sensor 15 detects and obtains the distance between the traction fixture and the reference plate 4 at this time. Then, the front support hydraulic cylinder 7 and the rear support hydraulic cylinder 8 act synchronously, pulling the lifting platform 6 down to the traction position.

[0060] Step 4: The diaphragm assembly is complete. Repeat steps 2 and 3 until all the diaphragms on the L-shaped rib unit are assembled and fixed.

[0061] The automatic assembly and positioning method is completed by the cooperation of a traction beam and a traction fixture. The traction beam and the traction fixture are equipped with a first electromagnet and a second electromagnet to ensure zero relative displacement between the diaphragm and the traction beam, and between the traction fixture and the L-shaped rib unit, eliminating cumulative positioning errors. During the traction of the diaphragm, a closed-loop control system using a distance sensor and a reference plate is used to provide real-time feedback on the deviation between the diaphragm and the target position. When the diaphragm reaches the assembly position, the traction hydraulic cylinder stops its action in a timely manner based on the feedback data, avoiding manual measurement errors and ensuring the assembly accuracy of the diaphragm. After the diaphragm is assembled, the traction hydraulic cylinder of the traction fixture can automatically flip over to assemble the fixed diaphragm with the help of a crossing support mechanism. After flipping over, the distance sensor is used for repositioning, breaking through the limitation of traditional fixtures that need to be disassembled and reassembled. This forms an automated measurement and positioning and continuous traction linkage mechanism, realizing high-precision continuous automated assembly of the diaphragm.
