Description

Technical Field

[0001] This invention relates to the field of steel structure clamping, specifically to an auxiliary clamping device for assembled steel structure docking. Background Technology

[0002] Prefabricated steel structure pipe fittings, with their advantages of high strength, light weight, and short construction period, are widely used in building construction, bridge engineering, municipal infrastructure, and industrial plants. In existing technologies, the connection process for steel structure pipe fittings typically involves the following steps: First, mechanical equipment is used to move the two pipe fittings to a pre-set workstation, where they are aligned manually or with simple tooling. Then, clamping tools such as clamps are used to fix both ends of the pipe fittings. After alignment, a handheld welding torch is used to spot weld the connection point to prevent displacement during welding. After spot welding, some clamping tools are removed to avoid interference, and then the pipe fittings are rotated manually or the welding torch is moved to complete the full circumference welding of the connection point. Finally, the remaining clamping tools are removed, and quality inspection is performed.

[0003] Existing clamping and welding equipment has significant limitations:

[0004] Clamping tools are mostly fixed structures with limited functions, which completely separate clamping from welding or other processes. After clamping and positioning, manual switching to welding is required, resulting in low construction efficiency. Pipe rotation relies on manual pushing or additional rotating mechanisms, increasing the labor intensity. The loading and unloading process relies on manual assistance, making continuous operation difficult or inefficient. Although some automated equipment can achieve clamping and welding linkage, it still cannot simultaneously complete rotation and welding during clamping and conveying. The overall process still has redundant steps, which restricts the key production efficiency of prefabricated steel structures. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide an auxiliary clamping device for the docking of prefabricated steel structures.

[0006] A prefabricated steel structure docking auxiliary clamping device includes a correspondingly arranged equipment base, two sets of main support plate assemblies are correspondingly arranged in the equipment base, the main support plate assembly includes two sets of support plate assemblies, the support plate assembly includes correspondingly arranged side support plates, a number of steel structure pipes are respectively placed on the two sets of main support plate assemblies, two adjacent sets of support plate assemblies are fixed on the equipment base, and the other two sets of support plate assemblies are driven and moved relative to each other by an adjustment mechanism provided on the equipment base;

[0007] The support plate assembly is equipped with a clamping mechanism that can simultaneously clamp and rotate the steel structure pipes within the main support plate assembly. The clamping mechanism is equipped with a material guiding mechanism that can alternately change the material guiding direction and is driven by the clamping mechanism. The equipment base is equipped with a drive device that simultaneously drives all clamping mechanisms to reciprocate and rotate. The support plate assembly is equipped with a material feeding structure that can feed the steel structure pipes one by one and is driven by the drive device. On the opposite surfaces of two adjacent clamping mechanisms in the two main support plate assemblies, there are reciprocating oscillating positioning mechanisms. The bottom end of the drive device is fitted with a welding device driven by the positioning mechanism. The welding device can weld the two steel structure pipes within the clamping mechanism. On the opposite surfaces of two adjacent support plates in the two main support plate assemblies, there are limiting components that can limit the positioning mechanism.

[0008] As an improvement, the equipment base includes a base with a slot. The side support plate includes a support that slides within the slot. The support plate is provided with a support plate. The opposite surfaces of the support plates corresponding to the support plate assembly are provided with grooves. Arc-shaped teeth are provided in the grooves. The clamping mechanism clamps and transports the steel structure pipe fittings by cooperating with the arc-shaped teeth.

[0009] As an improvement, the clamping mechanism includes a housing concentric with the arc-shaped gear, and a gear driven by a drive device is provided inside the housing. The gear includes a first gear, and a second gear with a smaller diameter is fixed to both ends of the first gear. An arc-shaped rack on the arc-shaped gear is correspondingly arranged with the gear. A clamping tooth is provided between the arc-shaped gear and the gear to clamp and transport the steel structure pipe. The two clamping teeth move alternately from the side end of the gear to the bottom end of the gear.

[0010] As an improvement, the clamping gear includes a clamping wheel 1 that meshes with both gear 1 and the arc-shaped gear. Both ends of the clamping wheel 1 are provided with clamping wheels 2 that are concentric with the clamping wheel. The clamping wheels 2 mesh with both gear 2 and the arc-shaped gear. Both clamping wheels 1 and clamping wheels 2 are provided with clamping grooves. The clamping groove of the clamping wheel 2 is provided with a rotating wheel that is tumblingly connected to the steel structure pipe fitting. The clamping groove of the clamping wheel 1 is provided with an anti-slip pad that fits against the steel structure pipe fitting.

[0011] As an improvement, the drive device includes a second transmission roller that passes through all gear components simultaneously. A driven gear and a driving wheel are fixedly connected to the second transmission roller. The welding device includes a movable support sleeved around the driven gear and the driving wheel. A rotating seat is provided on each of the two covers near the drive device. The positioning mechanism includes a rotating ring rotatably connected to the rotating seat. An end block and an extension plate are provided at the end of the rotating ring. A second insertion rod is rotatably provided on the end block. The second rotating seat is provided at the top of the cover. The second insertion rod is inserted into the second rotating seat. A second spring is provided between the end block and the second rotating seat and sleeved around the second insertion rod. An abutment rod is provided on the side end of the extension plate. A limiting member limits the positioning mechanism by contacting the abutment rod. The end of the extension plate is fixedly connected to the welding device. The welding device can weld two steel structure pipes in a docking state.

[0012] As an improvement, the upper and lower ends of the cover are respectively provided with an upper slot and a lower slot. The material guiding mechanism includes a material guiding block and a clamping plate that move on the upper slot. The clamping plate is located in the upper slot. The material guiding block is provided with a second slot. The second slot is provided with a through hole that passes through the clamping plate. A first insert rod is inserted into the through hole. The bottom end of the first insert rod is provided with a locking block that engages with a gear. The top end of the first insert rod is provided with a stop plate. A spring is provided between the stop plate and the top end of the inner wall of the second slot. The side support plate also includes a stop block located above the groove. Both ends of the top of the material guiding block are provided with material guiding surfaces that can alternately engage with the two side stop blocks.

[0013] As an improvement, the side support plate also includes a top plate located at the top of the support plate. Both of the two corresponding top plates have arc grooves on their opposite surfaces. The feeding structure includes a feeding wheel that rotates in the arc groove. All feeding wheels are passed through by a drive roller. A driven wheel is fixed to the drive roller. The driven wheel is driven by the drive wheel through a drive belt. The top of the top plate is provided with a material trough that can support the steel structure pipe fittings. There is a space between the two corresponding side support plates. Both the upper and lower ends of the feeding wheel are provided with clamping grooves. The steel structure pipe fittings enter the clamping grooves through the space between the two side support plates.

[0014] As an improvement, the welding device includes a movable support fixed to the extension plate. The movable support is symmetrically provided with welding modules opposite to the abutment rod. When the abutment rod abuts against the limiting member, the welding module above and the clamped steel structure pipe are on the same horizontal line. When the steel structure pipe is clamped and transported, the welding module can be driven to move with the steel structure pipe by contacting the abutment rod.

[0015] The advantages of this invention compared to the prior art are as follows:

[0016] The clamping mechanism consists of gear components and clamping gears. Clamping wheel one and clamping wheel two have different diameters and different rotation angles. This structural feature allows it to simultaneously move along an arc path and rotate the pipe to meet the welding requirements for one revolution while clamping the pipe. No additional equipment is needed to clamp, transport, or rotate the pipe separately, reducing process connection time and realizing the integration of "transportation-clamping-rotation". Compared with existing technologies, it eliminates the separate preparation step for spot welding.

[0017] The feeding wheel of the unloading structure has a clamping groove and is driven by a transmission roller to rotate intermittently. It can receive pipes in the trough one by one and transport them to the guiding mechanism. The guiding mechanism uses the guiding surface of the guiding block to cooperate with the abutment block, combined with the locking relationship between the insertion rod and the gear, to alternately change the guiding direction as the clamping mechanism moves. The combined structural features of the two enable automatic, precise, and continuous conveying of pipes from the trough to the clamping mechanism, reducing manual loading and improving the efficiency of loading and unloading.

[0018] The positioning mechanism includes a rotating ring and two springs. The moving support of the welding device carries symmetrical welding modules. When the positioning mechanism swings with the clamping mechanism, the welding device closely follows the movement of the pipe fitting, and the limiting component restricts the stroke of the positioning mechanism through the abutment rod. This structural feature, combined with the function of the clamping mechanism driving the pipe fitting to rotate, allows the welding module to move along the pipe fitting's revolution path and complete the full circumference welding at the joint by utilizing the pipe fitting's rotation. This eliminates the need for the step-by-step operation of "first spot welding for fixation and then full welding" in existing technologies, thus shortening the total welding time.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 As shown:

[0031] An assembly-type steel structure docking auxiliary clamping device includes a correspondingly arranged equipment base 1, two sets of main support plate assemblies are correspondingly arranged inside the equipment base 1, the main support plate assembly includes two sets of support plate assemblies, the support plate assembly includes correspondingly arranged side support plates 2, a number of steel structure pipes are respectively placed on the two sets of main support plate assemblies, two adjacent sets of support plate assemblies are fixed on the equipment base 1, and the other two sets of support plate assemblies are driven and moved relative to each other by an adjustment mechanism 4 provided on the equipment base 1;

[0032] The support plate assembly is equipped with a clamping mechanism 5 that can simultaneously clamp and rotate the steel structure pipes within the main support plate assembly. The clamping mechanism 5 is equipped with a guiding mechanism 7 that can alternately change the guiding direction and is driven by the clamping mechanism 5. The equipment base 1 is equipped with a driving device 11 that simultaneously drives all clamping mechanisms 5 to reciprocate. The support plate assembly is equipped with a feeding structure 3 that can feed the steel structure pipes one by one and is driven by the driving device 11. In the two sets of main support plate assemblies, each of the two adjacent clamping mechanisms 5 has a reciprocating oscillating positioning mechanism 8 on its opposite surface. The bottom end of the driving device 11 is fitted with a welding device 9 driven by the positioning mechanism 8. The welding device 9 can weld the two steel structure pipes within the clamping mechanism 5. In the two sets of main support plate assemblies, each of the two adjacent support plate assemblies has a limiting member 10 that can limit the positioning mechanism 8 on its opposite surface.

[0033] Working principle of this invention: The worker places the steel structure pipe fitting on the side support plate 2, and starts the drive device 11 to drive the clamping mechanism 5 and the unloading structure 3 to intermittently reciprocate. When the unloading structure 3 is working, it can transport the steel structure pipe fitting to the guiding mechanism 7, and then transport the steel structure pipe fitting to the clamping mechanism 5 through the guiding mechanism 7. When the clamping mechanism 5 is working, it can clamp the steel structure pipe fitting, and at the same time transport the steel structure pipe fitting to the bottom of the clamping mechanism 5, and then release the steel structure pipe fitting onto the equipment base 1 through the clamping mechanism 5. During the process, the clamping mechanism 5 can drive the steel structure pipe fitting to rotate, and the positioning mechanism 8 can follow the clamping mechanism 5 to reciprocate and swing. During the process, the welding device 9 welds two steel structure pipes that are in a docking state. When the steel structure pipes move to the bottom output position of the clamping mechanism 5, the positioning mechanism 8 continues to move from that position and moves rapidly under the action of the spring. Compared with the prior art, which requires alignment, spot welding and full welding before welding steel structure pipes, this invention has high welding efficiency. Moreover, the clamping mechanism 5 can not only perform welding while conveying the steel structure pipes, but also complete the function of alternating clamping and welding through reciprocating swing, which greatly reduces the time required for alignment, spot welding and other preparations before welding of steel structure pipes, and further improves the production efficiency of steel structure pipes.

[0034] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 6 Appendix Figure 8 Appendix Figure 9 As shown:

[0035] The equipment base 1 includes a base 101, on which a slot 107 is provided. The side support plate 2 includes a support 202 that slides within the slot 107. A support plate 201 is provided on the support 202. The opposite surfaces of the support plates 201 corresponding to the support plate assembly are provided with grooves 203. Arc-shaped teeth 204 are provided in the grooves 203. The clamping mechanism 5 clamps and transports the steel structure pipe by cooperating with the arc-shaped teeth 204.

[0036] The clamping mechanism 5 includes a housing 501 concentric with the arc-shaped gear 204. The housing 501 contains a gear driven by the drive device 11. The gear includes a first gear 505. Both ends of the first gear 505 are fixed with a second gear 506 with a diameter smaller than that of the first gear 505. The arc-shaped rack on the arc-shaped gear 204 is correspondingly arranged with the gear. The arc-shaped gear 204 and the gear are meshed with a clamping tooth that can clamp and transport the steel structure pipe. The two clamping teeth alternately move from the side end of the gear to the bottom end of the gear.

[0037] The clamping gear includes a clamping wheel 507 that meshes with both gear 505 and arc-shaped gear 204. Both ends of the clamping wheel 507 are provided with clamping wheels 508 that are concentric with the clamping wheel 507. The clamping wheels 508 mesh with both gear 506 and arc-shaped gear 204. Both the clamping wheel 507 and the clamping wheel 508 are provided with clamping grooves 509. The clamping groove 509 of the clamping wheel 508 is provided with a rotating wheel 510 that is tumblingly connected to the steel structure pipe fitting. The clamping groove 509 of the clamping wheel 507 is provided with an anti-slip pad 511 that fits against the steel structure pipe fitting.

[0038] Working principle of clamping mechanism 5: The drive device 11 is started to drive the gear to rotate back and forth. The clamping tooth can roll on the gear and the arc-shaped tooth 204 at the same time under the drive of the gear. That is, the specific movement path of the clamping tooth is the rolling path of the arc-shaped tooth 204. In this invention, the clamping groove 509 of one clamping tooth is located at the side end of the gear as the initial position, that is, the opening is upward. The other clamping tooth is located at the bottom end of the gear and the opening is downward. At this time, the steel structure pipe conveyed by the unloading structure 3 can fall into the clamping groove 509 with the opening upward through the guiding mechanism 7. When the welding is finished, the clamping tooth is located at the bottom end of the gear and the clamping groove 509 is open downward. At this time, the steel structure pipe can fall onto the equipment base 1 under the action of gravity.

[0039] In order to enable the clamping gear to clamp the steel structure pipe fitting during movement and drive the steel structure pipe fitting to rotate, the present invention provides clamping wheels 507 and 508 of different sizes, as shown in the attached figure. Figure 6As shown, the diameter of clamping wheel 507 is smaller than that of clamping wheel 508. Since clamping wheel 507 and clamping wheel 508 need to maintain coaxial rotation during movement, the diameters of gear 505, gear 506 and the corresponding arc rack are set accordingly. In order to satisfy the clamping function, the rotation of clamping wheel 507 is one more turn than that of clamping wheel 508. When the clamping gear moves from the side end of the gear to the bottom, the clamping grooves 509 of clamping wheel 507 and clamping wheel 508 are overlapping. Since the anti-slip pad 511 is in contact with the steel structure pipe, clamping wheel 508 can drive the steel structure pipe to rotate when it rotates. Since it is necessary to weld the joint of the steel structure pipe once, it is necessary to satisfy the requirement that the steel structure pipe rotates one turn relative to the welding device 9.

[0040] Therefore, assuming the revolution angle of the steel structure pipe fitting is 90°, the rotation angle of clamping wheel 508 must be at least 270°. Since the steel structure pipe fitting needs to be clamped, the rotation angle of clamping wheel 507 must be 630°.

[0041] The orbital radius R = R1 + R2 (radius of the sun gear R1 + radius of the planet gears R2);

[0042] The planetary gear's revolution angle (i.e., the planet carrier's rotation angle): θH;

[0043] Sun gear rotation angle: θ1;

[0044] The linear displacement of the sun gear at the meshing point: S1 = R1 * θ1;

[0045] Linear displacement caused by the revolution of the planetary carrier: S_revolution = R1 * θH (because during revolution, the center of the planetary gear rotates around the sun gear by θH, and the distance from the meshing point to the center of the sun gear is R1;

[0046] Linear displacement generated by its own rotation: S=R2*θ2 (the direction is opposite to the revolution displacement, because the direction of rotation is opposite to the direction of rotation of the sun gear during external meshing).

[0047] The meshing constraint requires that the linear displacements of the two are equal: R1*θ1=R1*θH+R2*θ2;

[0048] The expression for the rotation angle of the planetary gear can be obtained by rearranging: θ2=R1 / R2*(θ1-θH;

[0049] For example, in this invention, the rotation angle θ1 of the gear component is 150°, at which time R1 / R2 is 4.5 (the radius of clamping wheel 508 is R2), and R1 / R2 is 10.5 (the radius of clamping wheel 507 is R2).

[0050] At this point, the welding of the steel structure pipe fitting joint can be completed, so that the welding device 9 can not only completely weld the steel structure pipe fitting joint, but also allow the steel structure pipe fitting to fall smoothly into the clamping groove 509 and smoothly disengage from the clamping groove 509 after welding. Furthermore, the two clamping teeth can alternately clamp the steel structure pipe fitting, which greatly reduces the welding preparation time for the steel structure pipe fitting joint production.

[0051] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 8 Appendix Figure 9 As shown:

[0052] The drive device 11 includes a second transmission roller 1107 that passes through all gear components simultaneously. A driven gear 1104 and a driving wheel 1105 are fixedly connected to the second transmission roller 1107 and fit together. The welding device 9 includes a movable support 901 that is sleeved on the driven gear 1104 and the driving wheel 1105. Two covers 501 near the drive device 11 are each provided with a first rotating seat 504. The positioning mechanism 8 includes a rotating ring 801 that is rotatably connected to the first rotating seat 504. The end of the rotating ring 801 is provided with an end block 802 and an extension plate 806 respectively. A second insert rod 803 is rotatably provided on the end block 802. The top of the cover 501 is provided with the second rotating seat 804. The second insert rod 803 is inserted into the second rotating seat 804. A sleeved part is provided between the end block 802 and the second rotating seat 804. The spring 805 has an abutment rod 807 on the side of the extension plate 806. The limiting member 10 limits the positioning mechanism 8 by contacting the abutment rod 807. The end of the extension plate 806 is fixedly connected to the welding device 9. The welding device 9 can weld two steel structure pipes in a docking state. The limiting member 10 includes a fixing plate 1001 fixedly connected to the support plate 201. The bottom end of the fixing plate 1001 is provided with a contact block 1002 that abuts against the abutment rod 807. The end of the fixing plate 1001 is provided with a limiting plate 1003. The driving device 11 also includes a fixing seat 1101 fixedly connected to the bottom end of the baffle 104. The fixing seat 1101 is provided with a drive motor 1102. The drive motor 1102 is provided with a drive gear 1103 that meshes with the driven gear 1104.

[0053] Before the drive device 11 is started, the initial position of the abutment rod 807 is in contact with the bottom end of the contact block 1002. When the steel structure pipe falls into the clamping mechanism 5, the drive device 11 is started to rotate to one side. At this time, the steel structure pipe moves downward under the drive of the clamping mechanism 5. That is, the steel structure pipe applies downward pressure to the abutment rod 807 and drives the rotating ring 801 to rotate to one side through the abutment rod 807. During the process, the second spring 805 is gradually compressed, and the rotating ring 801 drives the welding device 9 to move with the steel structure pipe through the extension plate 806. Since the steel structure pipe will also rotate when it is making revolution, the welding device 9 can be started to weld the joint of the two steel structure pipes. Since the rotation angle of the steel structure pipe is greater than one revolution (630° as described above), the operator can set the start and stop time of the welding device 9 to weld the steel structure pipe one revolution.

[0054] When the steel structure pipe is at the bottom exit of the clamping mechanism 5, the steel structure pipe falls, but the abutment rod 807 will continue to move to one side due to its thickness. At this time, the spring 805 rotates from one side to the other side and converts the elastic potential energy into kinetic energy to drive the rotating ring 801 to rotate quickly to the position where the abutment rod 807 contacts the bottom of the limit member 10 on the other side.

[0055] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 6 Appendix Figure 7 Appendix Figure 5 Appendix Figure 9 As shown:

[0056] The cover 501 has an upper slot 502 and a lower slot 503 at its upper and lower ends, respectively. The material guiding mechanism 7 includes a material guiding block 701 and a clamping plate 703 that move on the upper slot 502. The clamping plate 703 is located in the upper slot 502. The material guiding block 701 has a second slot 704. The second slot 704 has a through hole 705 that passes through the clamping plate 703. A first insert rod 706 is inserted into the through hole 705. The bottom end of the first insert rod 706 has a snap-fit ​​block 707 that engages with a first gear 505. The top end of the first insert rod 706 has a stop plate 708. A first spring 709 is provided between the stop plate 708 and the top end of the inner wall of the second slot 704. The side support plate 2 also includes a stop block 205 located above the groove 203. The top ends of the material guiding block 701 have material guiding surfaces 702 that can alternately engage with the two side stop blocks 205.

[0057] When the drive device 11 is started, the guide mechanism 7 can rotate with the gear 505 as the gear 505 drives the clamping block 707. If the steel structure pipe is not moved to the bottom of the clamping mechanism 5 when the guide surface 702 contacts the abutment block 205, the clamping mechanism 5 continues to work. The bottom of the clamping block 707 is cylindrical. At this time, the teeth on the gear 505 will continuously press the clamping block 707 upward, causing the insertion rod 706 to spring up. At this time, the guide mechanism 7 has the function of guiding materials. When the steel structure pipe moves to the bottom of the clamping mechanism 5, the steel structure pipe falls onto the other guide surface 702 through the unloading structure 3, and then falls onto the clamping mechanism 5 through the other guide surface 702.

[0058] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 9 As shown:

[0059] The side support plate 2 also includes a top plate 206 located at the top of the support plate 201. Both of the two corresponding top plates 206 have arc grooves 207 on their opposite surfaces. The feeding structure 3 includes a feeding wheel 303 that rotates within the arc groove 207. All feeding wheels 303 are passed through by a transmission roller 302. A driven wheel 301 is fixedly connected to the transmission roller 302. The driven wheel 301 is driven by the driving wheel 1105 through a transmission belt 1106. The top of the top plate 206 is provided with a material trough 208 that can support steel structure pipe fittings. There is a space between the two corresponding side support plates 2. Both the upper and lower ends of the feeding wheel 303 are provided with a clamping groove 304. The steel structure pipe fittings enter the clamping groove 304 through the space between the two side support plates 2.

[0060] Working principle of feeding structure 3: When the drive device 11 is started, the driven wheel 301 and the transmission roller 302 are driven to rotate through the drive wheel 1105 and the transmission belt 1106. The transmission roller 302 drives the feeding wheel 303 to rotate. When the clamping groove 304 rotates to the top, the steel structure pipe can fall into the clamping groove 304 through the material groove 208. The rotation of the feeding wheel 303 drives the steel structure pipe to the bottom of the feeding wheel 303 and fall out of the clamping groove 304. When the clamping mechanism 5 is rotated to the position, the feeding wheel 303 is also rotated to the position, which has the function of automatically feeding the steel structure pipe from the material groove 208.

[0062] The welding device 9 includes a movable support 901 fixedly connected to the extension plate 806. A welding module 902 is symmetrically arranged on the movable support 901 relative to the abutment rod 807. When the abutment rod 807 abuts against the limiting member 10, the welding module 902 above is on the same horizontal line as the clamped steel structure pipe. When the steel structure pipe is clamped and transported, it can drive the welding module 902 to move along with the steel structure pipe by contacting the abutment rod 807. A support column 102 is provided on the base 101. A side plate 103 is provided on the support column 102. A baffle 104 is fixedly connected between the two side plates 103. A driven wheel 301 is rotatably mounted on the baffle 104. An end plate 105 is provided at both ends of the side plate 103. A sliding rod 106 passing through the top plate 206 is provided between the two end plates 105. A number of conveying rollers 108 are provided between the two bases 101.

[0064] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 9 As shown:

[0065] The adjustment mechanism 4 includes two rotating rods 401 that pass through two adjacent support plate assemblies in the two sets of main support plate assemblies and are located in the slot 107. The rotating rods 401 are provided with limiting blocks 402 that are rotatably connected to the side support plate 2. Both ends of the rotating rods 401 are provided with lead screws 403 that are threaded to other side support plates 2 and pass through the slot 107. The end of the lead screw 403 is fixedly connected to a transmission wheel 404. The end of the base 101 is provided with a first reversing wheel 405 and a second reversing wheel 406. The two transmission wheels 404 are connected to a first transmission belt 407 through the first reversing wheel 405 and the second reversing wheel 406. The end of the transmission wheel 404 is provided with an adjustment hole 408.

[0066] The adjustment mechanism 4 in this invention can support steel structure pipes of different lengths by adjusting the distance between the two sets of support plate assemblies in the main support plate assembly. Specifically, the transmission wheel 404 is rotated through the adjustment hole 408, and the two rotating rods 401 are driven to rotate simultaneously through the transmission wheel 404 and the transmission belt 407. Since both ends of the rotating rods 401 are provided with screw rods 403 that are threaded to other side support plates 2 and whose ends pass through the slot 107, the distance between the two sets of support plate assemblies in the two main support plate assemblies can be adjusted at this time.

[0067] In the specific implementation of this prefabricated steel structure docking auxiliary clamping equipment, the spacing of the support plate assembly is first adjusted according to the length of the steel structure pipe to be processed by the adjusting mechanism 4. Then, several steel structure pipes are placed into the material trough 208, and the drive device 11 is started to drive the gear component to rotate reciprocally. The transmission belt 1106 drives the feeding wheel 303 to rotate within the arc groove 207, and the feeding wheel 303 conveys the pipes one by one to the guiding mechanism 7. In the guiding mechanism 7, the gear 505 drives the guiding block 701 to rotate with the gear component, guiding the pipes to the clamping mechanism 5. When the clamping mechanism 5 is working, the anti-slip pad 511 of the clamping wheel 507 cooperates with the rotating wheel 510 of the clamping wheel 508 to clamp the pipes and drive the pipes to rotate. Simultaneously, the clamping gears alternately move from the side end to the bottom end of the gear component, realizing the conveying and rotation of the pipes. During this process, the positioning mechanism 8 swings, and the extension plate 806 drives the welding device 9 to move with the pipe fitting. The welding module 902 welds the joint of the two pipe fittings in the docking state for one revolution. When the pipe fitting is conveyed to the bottom of the clamping mechanism 5, it falls onto the conveyor roller 108 for output under the action of gravity. The second spring 805 releases potential energy to drive the rotating ring 801 to continue moving rapidly, so that the other welding module 902 is ready to weld the next pair of pipe fittings. The two clamping teeth work alternately in a cycle to complete the continuous steel structure pipe fitting docking clamping and welding operation.

[0068] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
