Abstract

This invention discloses a welding device and processing method for longitudinal truss beams of diaphragm wall reinforcement cages. It employs a track frame beam connected to an automatic mesh welding device, and connects a portal truss structure and a pod-type welding module to the track frame beam. The portal truss structure and the pod-type welding module can move axially and reset on the track frame beam. The pod-type welding module is erected on the longitudinal truss beam, so that when the longitudinal truss beam moves to the automatic mesh welding device, the portal truss structure can drive the pod-type welding module to move on the longitudinal truss beam. Simultaneously, the pod-type welding module can detect the position information of the longitudinal truss beam, clamp the longitudinal truss beam, and move synchronously with the longitudinal truss beam. During synchronous movement, the pod-type welding module moves on the longitudinal truss beam to weld it, eliminating the need to pre-weld the longitudinal truss beam, improving processing efficiency and reducing manual labor intensity.

Description

Technical Field

[0001] This invention relates to the field of building engineering, specifically to a welding and processing technology for longitudinal truss beams of diaphragm wall steel cages. Background Technology

[0002] At present, the processing and forming of diaphragm wall reinforcement cages still heavily relies on manual labor. When laying longitudinal reinforcement, multiple steel bars are usually spliced ​​together and laid out by multiple people working together, which results in low processing efficiency and high labor intensity.

[0003] Chinese patent application CN 117696791 A discloses an intelligent equipment for forming diaphragm wall steel cages. Through the multi-machine linkage of an automatic longitudinal bar picking device, an automatic longitudinal bar feeding device, a longitudinal bar laying platform, an automatic transverse bar feeding platform, an automatic transverse bar laying device, an automatic mesh welding device, an upper and lower mesh lifting bracket, and a mesh dragging device, the equipment ultimately realizes intelligent and manpower-reduced operation of steel bar preparation, processing, laying, and welding processes for diaphragm wall steel cages.

[0004] However, the above-mentioned scheme for forming the diaphragm wall reinforcement cage requires the longitudinal truss beams to be welded in advance for installation. Then, two truss gantry cranes are used to lift the longitudinal truss beams simultaneously, and then the longitudinal truss beams are connected to the reinforcement cage, which consumes more manpower and time. In addition, considering the overall rigidity of the longitudinal truss beams, the longitudinal truss beams are prone to large bending deformation during the lifting process, which increases the difficulty of the operation.

[0005] Therefore, how to effectively improve the processing and forming efficiency of longitudinal truss beams in diaphragm wall reinforcement cages and reduce the labor intensity of workers has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a welding equipment and processing method for longitudinal truss beams of diaphragm wall steel cages that can save labor and improve work efficiency.

[0007] To achieve the above objectives, the present invention provides a longitudinal truss beam welding device for diaphragm wall reinforcement cages, used in conjunction with an automatic mesh welding device for longitudinal truss beams and mesh panels. The automatic mesh welding device is configured with adjustable height.

[0008] The track frame beam is connected to the automatic mesh welding equipment via a hoisting steel pipe assembly. The hoisting steel pipe assembly is configured to adjust the connection height of the track frame beam and to move the track frame beam perpendicular to the automatic mesh welding equipment.

[0009] A portal truss structure, connected to the track frame beam, is configured to move axially on the track frame beam and return to its original position.

[0010] A pod-type welding module is connected to the portal truss structure and erected on the longitudinal truss beams. It is configured to detect the position information of the longitudinal truss beams to clamp them, move synchronously with them, and, during this synchronous movement, move on the longitudinal truss beams to perform welding.

[0011] The central control system is configured to control the clamping and movement states of the podded welding module based on the position information of the longitudinal truss beam.

[0012] Furthermore, the automatic mesh welding equipment includes a first lifting support truss and a second lifting support truss disposed above the first lifting support truss. The first lifting support truss is provided with a variable angle welding assembly, and the second lifting support truss is slidably connected to the hoisting steel pipe assembly through an H-shaped steel beam.

[0013] Furthermore, the track frame beam includes a frame beam, slide rails disposed on both sides of the frame beam, a piston rod disposed below the frame beam, and a lifting component disposed in the frame beam for cooperating with the lifting steel pipe assembly.

[0014] Furthermore, the portal truss structure includes square tube columns, portal longitudinal beams and support plates mounted on the square tube columns, with sliders at both ends of the portal longitudinal beams for cooperating with the slide rails, and a cylinder for cooperating with the piston rod on the support plate.

[0015] Furthermore, the podded welding module includes a column, a hook plate disposed on the top of the column for cooperating with the support plate, and three podded longitudinal beams distributed in the middle region of the column. The first podded longitudinal beam is provided with a grooved wheel for slidingly cooperating with the upper longitudinal rib of the longitudinal truss beam and a pneumatic clamping finger for clamping the upper longitudinal rib. The second and third podded longitudinal beams are respectively provided with welding torch assemblies for welding the longitudinal truss beam, and the welding torch assemblies can move axially along the second and third podded longitudinal beams.

[0016] Furthermore, the welding torch assembly on the second pod longitudinal beam corresponds to the top of the upper longitudinal reinforcement and Z-reinforcement of the longitudinal truss beam, and the welding torch assembly on the third pod longitudinal beam corresponds to the bottom of the lower longitudinal reinforcement and Z-reinforcement of the longitudinal truss beam.

[0017] Furthermore, a guide beam is provided at the bottom of the column, and the guide beam is connected to both sides of the column by diagonal bracing beams. A proximity switch is provided on the diagonal bracing beam, and the proximity switch is configured to detect the movement position of the Z-rib in the longitudinal truss beam.

[0018] Furthermore, the guide beam is configured with outward expansion at both ends.

[0019] To achieve the above objectives, the present invention provides a method for processing longitudinal truss beams of diaphragm wall reinforcement cages, based on the aforementioned welding equipment for longitudinal truss beams of diaphragm wall reinforcement cages, the processing method comprising:

[0020] The track frame beams are connected to the automatic mesh welding equipment via hoisting steel pipe assemblies, and then the portal truss structure and pod-type welding modules are installed.

[0021] Welding of the lower mesh panels is carried out.

[0022] The Z-bars of the longitudinal truss beams are initially spot-welded to the upper and lower longitudinal bars respectively.

[0023] Simultaneously move the lower mesh and longitudinal truss beams to perform the fixed-point placement and welding of the transverse reinforcement.

[0024] When the podded welding module detects that the Z-rib is moving close to it, the central control system controls the podded welding module to clamp the upper longitudinal rib, so that the podded welding module moves synchronously with the longitudinal truss beam.

[0025] Simultaneously, the welding torch assembly moves axially along the longitudinal truss beam, synchronously performing segmental welding of the Z-ribs to the upper and lower longitudinal ribs.

[0026] After welding is completed, the portal truss structure drives the pod-type welding module to move and reset on the track frame beam.

[0027] Furthermore, if the welding torch assembly performs single-sided welding on the longitudinal truss beam, the welding torch assembly moves by 5d; if the welding torch assembly performs double-sided welding on the longitudinal truss beam, the welding torch assembly moves by 10d, where d is the diameter of the upper and lower longitudinal reinforcement bars.

[0028] The present invention provides a welding device and processing method for longitudinal truss beams of diaphragm wall reinforcement cages. It employs an automatic mesh welding device connected to a track frame beam, and connects a portal truss structure and a pod-type welding module to the track frame beam. The portal truss structure and the pod-type welding module can move axially and reset on the track frame beam. The pod-type welding module is erected on the longitudinal truss beam, so that when the longitudinal truss beam moves to the automatic mesh welding device, the portal truss structure can drive the pod-type welding module to move on the longitudinal truss beam. Simultaneously, the pod-type welding module can clamp the longitudinal truss beam, allowing the pod-type welding module to move synchronously with the longitudinal truss beam, and to perform welding on the longitudinal truss beam during this synchronous movement.

[0029] Furthermore, the podded welding module can also detect the movement position of the longitudinal truss beam, enabling the control system to be configured to control the clamping and movement states of the podded welding module based on the movement position of the longitudinal truss beam. This improves the accuracy of the fit between the podded welding module and the longitudinal truss beam, thereby increasing the welding efficiency of the longitudinal truss beam.

[0030] Therefore, the track frame beam, portal truss structure and pod-type welding module work together to weld the longitudinal truss beam, eliminating the need to pre-weld the longitudinal truss beam, improving processing efficiency and reducing manual labor intensity.

[0045] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0046] See also Figure 1 and Figure 2 The image shows an example of a welding device for longitudinal truss beams of diaphragm wall reinforcement cages provided by the present invention.

[0047] As shown in the figure, the welding equipment for the longitudinal truss beam of the diaphragm wall reinforcement cage in this example is used in conjunction with the longitudinal truss beam 100 and the automatic mesh welding equipment 200. It mainly includes the track frame beam 300, the portal truss structure 400, the pod-type welding module 500, the hoisting steel pipe assembly 600 and the central control system.

[0048] The track frame beam 300 is connected to the automatic mesh welding equipment 200 via the hoisting steel pipe assembly 600. The hoisting steel pipe assembly 600 can move axially along the automatic mesh welding equipment 200 to drive the track frame beam 300 to move axially. The portal truss structure 400 is connected to the track frame beam 300 and is configured to move axially on the track frame beam 300 and reset. At the same time, the pod-type welding module 500 is connected to the portal truss structure 400 and is erected on the longitudinal truss beam 100, so that the portal truss structure 400 can drive the pod-type welding module 500 to move axially along the longitudinal truss beam 100. The pod-type welding module 500 is configured to clamp the longitudinal truss beam 100, move synchronously with the longitudinal truss beam 100, move on the longitudinal truss beam 100 and weld the longitudinal truss beam 100, and detect the movement position of the longitudinal truss beam 100.

[0049] Furthermore, the central control system is configured to control the clamping and movement states of the podded welding module 500 according to the moving position of the longitudinal truss beam 100, so as to improve the matching accuracy between the podded welding module 500 and the longitudinal truss beam 100 and improve the welding efficiency of the longitudinal truss beam 100.

[0050] Thus, the track frame beam 300, the portal truss structure 400 and the pod-type welding module 500 work together to weld the longitudinal truss beam 100, eliminating the need to pre-weld the longitudinal truss beam, improving processing efficiency and reducing manual labor intensity.

[0051] Among them, combined Figure 2 The track frame beam 300 mainly includes a frame beam 310, a slide rail 320, a piston rod 330, and a lifting component 340. The frame beam 310, slide rail 320, piston rod 330, and lifting component 340 can cooperate to connect the automatic mesh welding equipment 200 and the portal truss structure 400. The automatic mesh welding equipment 200 moves axially, while the portal truss structure 400 moves axially, thereby enabling the pod-type welding module 500 to cooperate with the longitudinal truss beam 100 for welding.

[0052] Specifically, in combination Figure 3 The frame beam 310 is composed of two frame longitudinal beams 311 and two frame transverse beams 312 connected to each other. The middle area of ​​the two frame longitudinal beams 311 is provided with a lifting component 340. Preferably, the lifting component 340 is respectively set at both ends of the frame beam 310, so that the lifting component 340 can cooperate with the lifting steel pipe assembly 600 to stably connect the automatic mesh welding equipment 200, and move axially on the automatic mesh welding equipment 200 through the lifting steel pipe assembly 600.

[0053] Furthermore, two parallel slide rails 320 are respectively provided on the outside of the frame longitudinal beam 311, so that the slide rails 320 can be slidably connected and cooperate with the portal truss structure 400, and the portal truss structure 400 can move axially along the track frame beam 300 through the slide rails 320.

[0054] Furthermore, the frame beams 312 at both ends of the frame beam 310 are respectively provided with gusset plates 313 extending to the bottom of the frame beam 310, and the gusset plates 313 at both ends are respectively connected by piston rods 330, so that the piston rods 330 can cooperate with the cylinder on the portal truss structure 400 to drive the portal truss structure 400 to move and reset.

[0055] The resulting track frame beam 300 can slidably connect the automatic mesh welding equipment 200 and the portal truss structure 400. It can also connect the lifting steel pipe assembly 600 via the lifting component 340 to move axially on the automatic mesh welding equipment 200. This allows the welding equipment to move axially and cooperate with multiple welding positions of the longitudinal truss beam 100. Furthermore, the sliding rail 320 and piston rod 330 drive the portal truss structure 400 to move axially and reset, enabling the welding equipment to move on the longitudinal truss beam 100 to weld it, thereby improving processing efficiency.

[0056] In order for the portal truss structure 400 to be connected with the track frame beam 300 and to move axially on the track frame beam 300, and at the same time drive the pod-type welding module 500 to be welded with the longitudinal truss beam 100, the portal truss structure 400 mainly includes square tube columns 410, sliders 420 and cylinders 430. The square tube columns 410, sliders 420 and cylinders 430 can be connected with the track frame beam 300 and the pod-type welding module 500, move axially on the track frame beam 300, and drive the pod-type welding module 500 to move synchronously.

[0057] Specifically, in combination Figure 4 A portal longitudinal beam 411 is provided above the square tube column 410. Support plates 412 are provided at both ends of the portal longitudinal beam 411. Two parallel sliders 420 are provided inside the support plates 412 and are correspondingly matched with two slide rails 320 on the outer side of the frame longitudinal beam 311 of the track frame beam 300, so that the sliders 420 can be placed in the slide rails 320 and move axially along the slide rails 320, thereby driving the portal truss structure 400 to move axially on the track frame beam 300.

[0058] Furthermore, a support beam 412 is provided on the outer side of the square tube column 410. There is a gap between the support beam 412 and the portal longitudinal beam 411. A support plate 413 is provided on the support beam 412. The cylinder body 430 is set on the support plate 413, so that the piston rod 330 below the frame longitudinal beam 311 of the track frame beam 300 can pass through the cylinder body 430 and cooperate with the cylinder body 430 to form a cylinder motion system, which can drive the portal truss structure 400 to move and reset.

[0059] As a preferred configuration, the piston rod 330 and the cylinder 430 cooperate to form a magnetically coupled rodless cylinder. The permanent magnet inside the piston rod 330 can move under the action of magnetic force, thereby driving the cylinder 430 to move synchronously, so as to drive the portal truss structure 400 to move. Here, the maximum stroke of the permanent magnet inside the piston rod is preferably configured to be 1000mm, so as to accurately control the movement state of the portal truss structure 400.

[0060] Furthermore, the lower part of the square tube column 410 has several horizontal through holes 414 distributed along the height direction. The pins inserted into the horizontal through holes 414 can connect the pod-type welding module 500. The pins inserted into the horizontal through holes 414 at different heights can adjust the connection height between the portal truss structure 400 and the pod-type welding module 500, so that the pod-type welding module 500 can be accurately erected on the longitudinal truss beam 100, thereby enabling precise fitting and welding of the longitudinal truss beam 100.

[0061] The portal truss structure 400 thus formed can be slidably connected to the track frame beam 300 via the slider 420 and move axially. The portal truss structure 400 is moved and reset via the cylinder 430, and is stably connected to the pod-type welding module 500 via the square tube column 410.

[0062] The pod-type welding module 500, which works in conjunction with this, mainly includes a hook plate 510, a grooved wheel 520, and a welding gun assembly 530. The hook plate 510, the grooved wheel 520, and the welding gun assembly 530 can be connected to the portal truss structure 400 and move synchronously with the portal truss structure 400. They can also be slidably connected to the longitudinal truss beam 100 and move and weld on the longitudinal truss beam 100.

[0063] Specifically, in combination Figure 2 , Figure 5 and Figure 6 The pod-type welding module 500 includes two columns 511 spaced apart. Hook plates 510 are respectively installed on the top of the two columns 511. By inserting pins into the horizontal through holes 414 of the portal truss structure 400 and the hook plates 510, the pod-type welding module 500 and the portal truss structure 400 can be fixedly connected, so that the portal truss structure 400 can move axially on the track frame beam 300, which can drive the pod-type welding module 500 to move synchronously.

[0064] Furthermore, three pod longitudinal beams are distributed in the middle area of ​​the column 511. The first pod longitudinal beam 512 is set in the upper area of ​​the column 511. Grooved wheel supports 513 are respectively provided at both ends of the first pod longitudinal beam 512, so that the grooved wheel 520 can be placed in the grooved wheel support 513. The grooved wheel 520 is placed on the upper longitudinal reinforcement 110 of the longitudinal truss beam 100 and rolls in the grooved wheel support 513, which can drive the pod welding module 500 to move axially on the longitudinal truss beam 100 to the welding position, thereby accurately welding the longitudinal truss beam 100.

[0065] Meanwhile, the second pod longitudinal beam 514 and the third pod longitudinal beam 515 are respectively located in the lower area and bottom of the column 511, and screw rails 516 are respectively provided on the second pod longitudinal beam 514 and the third pod longitudinal beam 515. The welding torch assembly 530 is connected to the screw rails 516 through the slide table 517, so that the slide table 517 moves axially on the screw rails 516, which can drive the welding torch assembly 530 to move synchronously and weld at different positions of the longitudinal truss beam 100.

[0066] Among them, combined Figure 2 The welding torch assembly 530 on the second pod longitudinal beam 514 corresponds to the top of the upper longitudinal rib 110 and Z-rib 120 of the longitudinal truss beam 100. The welding torch assembly 530 can move axially on the second pod longitudinal beam 514 to perform segment welding at the connection between the top of the upper longitudinal rib 110 and Z-rib 120, ensuring the connection stability of the upper longitudinal rib 110 and Z-rib 120.

[0067] Similarly, the welding torch assembly 530 on the third pod longitudinal beam 515 corresponds to the bottom ends of the lower longitudinal reinforcement 130 and Z-reinforcement 120 of the longitudinal truss beam 100. The welding torch assembly 530 moves axially on the third pod longitudinal beam 515, and can perform segment welding at the connection of the bottom ends of the lower longitudinal reinforcement 130 and Z-reinforcement 120 to ensure the connection stability of the lower longitudinal reinforcement 130 and Z-reinforcement 120.

[0068] Because the length of the fit between the bottom end of Z-reinforcement 120 and the lower longitudinal reinforcement 130 is relatively large, the third pod longitudinal beam 515 is configured to have a longer length than the second pod longitudinal beam 514, and is adapted to the fit length between the bottom end of Z-reinforcement 120 and the lower longitudinal reinforcement 130.

[0069] The welding torch assembly 530 thus formed can move stably axially on the second pod longitudinal beam 514 and the third pod longitudinal beam 515 respectively through the cooperation of the slide table 517 and the lead screw slide rail 516. It can perform segment welding on the connection areas of the upper longitudinal reinforcement 110, Z reinforcement 120 and lower longitudinal reinforcement 130 in the longitudinal truss beam 100 respectively, so as to ensure the connection tightness of the longitudinal truss beam 100.

[0070] Furthermore, combined Figure 5 The podded welding module 500 also includes pneumatic clamping fingers 540 and proximity switches 550. The pneumatic clamping fingers 540 and proximity switches 550 are connected to the central control system, so that the central control system can control the working state of the pneumatic clamping fingers 540 according to the proximity switches 550, and fix the podded welding module 500 on the upper longitudinal reinforcement 110. It can move synchronously with the longitudinal truss beam 100, so that the welding of the longitudinal truss beam 100 can be realized synchronously during the processing and movement of the steel cage, without the need to weld the longitudinal truss beam 100 in advance, thus improving processing efficiency.

[0071] Specifically, the bottom of the column 511 is provided with a guide beam 518, and the guide beam 518 is connected to both sides of the column by diagonal bracing beams 519, so that the guide beam 518 and the column 511 cooperate to form a stable connection structure through the diagonal bracing beams 519. A proximity switch 550 is provided on the diagonal bracing beam 519. The proximity switch 550 is configured to detect the position information of the Z-rib 120 in the longitudinal truss beam 100. When the Z-rib 120 moves close to the pod-type welding module 500, and the proximity switch 550 detects the Z-rib 120, the proximity switch 550 will transmit a proximity signal to the central control system, so that the central control system issues a start command to the pneumatic clamping finger 540, so that the pneumatic clamping finger 540 works to clamp the longitudinal truss beam 100.

[0072] Furthermore, the pneumatic clamping fingers 540 are located at both ends of the first pod longitudinal beam 512, so that the central control system can control the pneumatic clamping fingers 540 to clamp the upper longitudinal rib 110 of the longitudinal truss beam 100, and fix the pod-type welding module 500 on the upper longitudinal rib 110 of the longitudinal truss beam 100, so that it can move synchronously with the longitudinal truss beam 100.

[0073] Meanwhile, the pneumatic clamping fingers 540 clamping the upper longitudinal ribs 110 of the longitudinal truss beam 100 also ensures that the podded welding module 500 remains fixedly connected to the longitudinal truss beam 100. The axial force generated by the axial movement of the welding torch assembly 530 on the second podded longitudinal beam 514 and the third podded longitudinal beam 515 will not cause the podded welding module 500 to move on the upper longitudinal ribs 110. It can stably move axially on the second podded longitudinal beam 514 and the third podded longitudinal beam 515 to stably weld the longitudinal truss beam 100.

[0074] Furthermore, combined Figure 6 The guide beam 518 is configured with outward expansion at both ends to avoid collision between the welding equipment and the Z-rib 120 of the longitudinal truss beam 100 during movement.

[0075] The podded welding module 500 thus formed is stably connected to the portal truss structure 400 via hook plate 510. It is supported on the upper longitudinal rib 110 of the longitudinal truss beam 100 via grooved wheel 520, so that the portal truss structure 400 can drive the podded welding module 500 to move axially on the longitudinal truss beam 100 for accurate welding. It also clamps the upper longitudinal rib 110 with the cooperation of proximity switch 550 and pneumatic clamping finger 540, so that the podded welding module 500 is stably connected to the longitudinal truss beam 100 and moves synchronously with the longitudinal truss beam 100. During the movement, the welding torch assembly 530 moves axially stably on the second podded longitudinal beam 514 and the third podded longitudinal beam 515, so as to perform segment welding on the connection areas of the upper longitudinal rib 110, Z-rib 120 and lower longitudinal rib 130 in the longitudinal truss beam 100, respectively, to ensure the connection tightness of the longitudinal truss beam 100 and improve the processing efficiency.

[0076] To illustrate the implementation scheme of this saddle welding equipment, the connection and coordination scheme between the track frame beam 300 and the automatic mesh welding equipment 200 is described in detail below.

[0077] In this example, the automatic wire mesh welding equipment 200 includes a first lifting support truss 210 and a second lifting support truss 220 disposed above the first lifting support truss 210. The first and second lifting support trusses 210 and 220 are configured to be height-adjustable. The track frame beam 300 is slidably connected to the second lifting support truss 220 through the lifting component 340 and the lifting steel pipe assembly 600, so that the track frame beam 300 can be adjusted in height and moved, ensuring the accuracy of the fit between the welding equipment and the longitudinal truss beam 100.

[0078] Combination Figure 1 Specifically, the first lifting support truss 210 is composed of a first hydraulic outrigger 211, a first truss crossbeam 212 and a first truss connecting beam 213 connected together. The truss connecting beam 213 is provided with a variable angle welding assembly 214 for welding steel cage mesh.

[0079] Similarly, the second lifting support truss 220 is composed of a second hydraulic outrigger 221, a second truss beam 222, and a second truss connecting beam 223 connected together. The second hydraulic outrigger 221 is set on the first truss connecting beam 213 of the first lifting support truss 210. By raising and lowering the first hydraulic outrigger 211 and the second hydraulic outrigger 221 respectively, the height of the automatic mesh welding equipment 200 can be precisely adjusted, thereby adapting to the welding height of the welding equipment and the longitudinal truss beam 100.

[0080] Furthermore, the second truss connecting beam 223 of the second lifting support truss 220 is connected to both ends of the H-beam 224, and the hoisting steel pipe assembly 600 is set on the H-beam 224, so that the track frame beam 300 of this saddle welding equipment can be connected to the automatic mesh welding equipment 200 through the hoisting steel pipe assembly 600.

[0081] Combination Figure 7 In conjunction with this, the hoisting steel pipe assembly 600 includes a clamp 610, a hoisting fitting 620, and a hoisting steel pipe 630. The clamp 610 is connected to the hoisting fitting 620, and the hoisting fitting 620 is installed on the hoisting steel pipe 630, so that the clamp 610, the hoisting fitting 620, and the hoisting steel pipe 630 cooperate with each other to connect the second lifting support truss 220 and the track frame beam 300.

[0082] Furthermore, the clamp 610 is configured as a groove structure that matches the flange plate of the H-beam 224, and a roller is provided in the groove, so that the clamp 610 can be clamped on the flange plate of the H-beam 224 and move along the axial direction of the H-beam 224 through the roller, thereby driving the track frame beam 300 to move.

[0083] Meanwhile, the hoisting steel pipe 630 can be inserted and fixed in the hoisting component 340 of the track frame beam 300, connecting the track frame beam 300 with the second lifting support truss 220, so that the track frame beam 300 can move perpendicularly to the second lifting support truss 220 through the clamp 610.

[0084] Furthermore, the hoisting steel pipe 630 has several pin holes distributed along the height direction, and the hoisting fitting 620 is provided with mounting holes that mate with the pin holes. By cooperating the hoisting fitting 620 with the pin holes at different heights on the hoisting steel pipe 630, the connection height between the clamp 610 and the H-beam 224 can be adjusted, thereby adjusting the connection height between the track frame beam 300 and the second lifting support truss 220.

[0085] The hoisting steel pipe assembly 600 thus constitutes a stable connection between the track frame beam 300 and the second lifting support truss 220, allowing the track frame beam 300 to move vertically on the second lifting support truss 220 and adjust the height of the track frame beam 300, so that the welding equipment can be precisely matched with the longitudinal truss beam 100.

[0086] This constitutes the welding equipment for the longitudinal truss beam of the diaphragm wall reinforcement cage provided in this solution.

[0087] This invention also provides a method for processing longitudinal truss beams of diaphragm wall reinforcement cages. Based on the above-mentioned welding equipment for longitudinal truss beams of diaphragm wall reinforcement cages, this processing method includes:

[0088] First, connect this saddle welding equipment to the automatic wire mesh welding equipment 200.

[0089] Combination Figure 1 and Figure 2 The second lifting support truss 220 is set on the first lifting support truss 210 to form the automatic mesh welding equipment 200 in this scheme, and then the hoisting steel pipe assembly 600 is installed on the H-shaped steel beam 224 of the second lifting support truss 220.

[0090] Next, the hoisting component 340 of the track frame beam 300 is connected to the hoisting steel pipe assembly 600 so that the track frame beam 300 can move perpendicularly to the automatic mesh welding equipment 200. At the same time, the connection height between the hoisting fitting component 620 and the hoisting steel pipe 630 is adjusted to adjust the connection height between the track frame beam 300 and the second lifting support truss 220.

[0091] At that time, the slider 420 on the portal truss structure 400 will be connected to the slide rail 320 of the track frame beam 300, and the piston rod 330 of the track frame beam 300 can be inserted into the cylinder 430 of the portal truss structure 400 to connect the portal truss structure 400 and the track frame beam 300, so that the portal truss structure 400 can move axially on the track frame beam 300 and reset.

[0092] Furthermore, the hook plate 510 of the podded welding module 500 is connected to the square tube column 410 of the portal truss structure 400. The connection height between the hook plate 510 and the square tube column 410 is adjusted to adjust the connection height between the podded welding module 500 and the portal truss structure 400, so that the podded welding module 500 and the portal truss structure 400 are stably connected, and the portal truss structure 400 drives the podded welding module 500 to move synchronously.

[0093] The next step is to weld the lower mesh panels.

[0094] The longitudinal ribs are automatically placed at fixed points on the longitudinal rib placement platform by the longitudinal rib automatic material inspection equipment and the longitudinal rib automatic feeding equipment in sequence; after the first longitudinal rib placement is completed, a transverse rib is welded to each end of the longitudinal rib to connect all the longitudinal ribs, and then at least three longitudinal ribs are extended by steel sleeves, and the other side of the extended longitudinal ribs is connected to the towing spreader of the mesh towing equipment.

[0095] Next, the longitudinal truss beam 100 is initially fixed.

[0096] The Z-bar 120 of the longitudinal truss beam 100 is spot-welded to the upper longitudinal bar 110 and the lower longitudinal bar 120 respectively.

[0097] Furthermore, the horizontal reinforcement bars are connected.

[0098] The lower mesh is moved synchronously and at a uniform speed with the longitudinal truss beam 100 by a mesh dragging device, and then the transverse reinforcement is laid out at fixed points, positioned and welded, and the intersection of the transverse and longitudinal reinforcements is welded by an automatic transverse reinforcement laying device.

[0099] Finally, the longitudinal truss beam 100 was fixed by segment welding.

[0100] The longitudinal truss beam 100 is moved to the automatic mesh welding equipment 200. The automatic mesh welding equipment 200 adjusts its height through hydraulic outriggers. At the same time, the connection height between the track frame beam 300 and the automatic mesh welding equipment 200 is adjusted through the hoisting steel pipe assembly 600 and the hoisting bracket 240, so that the groove wheel 520 of the pod-type welding module 500 is placed on the upper longitudinal reinforcement 110 of the longitudinal truss beam 100.

[0101] Next, the portal truss structure 400 moves axially on the track frame beam 300 through the cooperation of the slider 420 and the slide rail 320, so as to drive the pod-type welding module 500 to move axially along the upper longitudinal reinforcement 110 of the longitudinal truss beam 100, and move to the connection area between the Z reinforcement 120 and the upper longitudinal reinforcement 110 and the lower longitudinal reinforcement 120.

[0102] As the longitudinal truss beam 100 and the podded welding module 500 gradually move closer, the proximity switch 550 in the podded welding module 500 detects the Z-rib 120 and transmits a proximity signal to the central control system, so that the central control system issues a start command to the pneumatic clamping finger 540, causing the pneumatic clamping finger 540 to work and clamp the longitudinal truss beam 100, and the podded welding module 500 and the longitudinal truss beam 100 move synchronously.

[0103] During the movement, the welding gun assembly 530 on the second pod longitudinal beam 514 and the third pod longitudinal beam 515 moves axially along the screw rail 516 via the slide table 517, and moves axially on the second pod longitudinal beam 514 and the third pod longitudinal beam 515 respectively, so as to perform segment welding on the connection area between the Z-rib 120 and the upper longitudinal rib 110 and the lower longitudinal rib 120 respectively, so that the longitudinal truss beam 100 is formed synchronously during the movement.

[0104] Furthermore, if the welding torch assembly 530 performs single-sided welding on the longitudinal truss beam 100, the welding torch assembly 530 moves by 5d; if the welding torch assembly 530 performs double-sided welding on the longitudinal truss beam 100, the welding torch assembly 530 moves by 10d, where d is the diameter of the upper and lower longitudinal ribs, in order to ensure the structural stability of the longitudinal truss beam 100.

[0105] After the section welding is completed, the piston rod 330 in the track frame beam 300 cooperates with the cylinder 430 of the portal truss structure 400 to drive the portal truss structure 400 and the pod-type welding module 500 to move and reset synchronously.

[0106] The saddle welding equipment and processing method for longitudinal truss beams of diaphragm wall reinforcement cages provided by the present invention, through the cooperation of track frame beam 300, portal truss structure 400, pod-type welding module 500, hoisting steel pipe assembly 600 and central control system, and connected with mesh automatic welding equipment 200, constitutes saddle welding equipment. It can realize the simultaneous welding of longitudinal truss beams 100 during the processing of reinforcement cages, without the need for manual welding of longitudinal truss beams 100 in advance, thereby improving processing efficiency and reducing labor intensity.

[0107] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
