Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and particularly relates to a welding equipment for processing highway isolation guardrails. Background Art

[0002] In the main urban road sections, phenomena such as pedestrians crossing the road horizontally at will and vehicles turning around at will are relatively common. Therefore, road traffic isolation guardrails are generally set in the central median of the road to prevent pedestrians from crossing the road and to warn and force oncoming motor vehicles to drive in separate lanes. The traffic isolation guardrails are usually made of steel, and the guardrail crossbeams and guardrail vertical beams of the traffic isolation guardrails need to be assembled and welded.

[0003] Most of the existing methods for processing highway isolation guardrails require the use of welding equipment. For example, when processing the isolation guardrails for municipal roads, multiple vertical rods are stacked on the welding rack, and then the upper and lower crossbars are brought into contact with the ends of the vertical rods for welding processing. For the existing equipment for welding and processing isolation guardrails, only multiple vertical rods are sequentially stacked on the welding rack, and the stacked vertical rods are manually pressed and fixed to bring the vertical rods to be welded into contact with the crossbars to achieve welding processing. Obviously, this method will not only reduce the precision and quality of the welding processing of the isolation guardrails, but also easily cause unnecessary safety hazards to the operators, and it is also difficult to quickly weld isolation guardrails of different heights.

An adjusting screw rod is rotatably connected to the pushing column, and the adjusting screw rod passes through the threaded hole and is located outside the support guide pipe.

[0009] Further, a limit buckling assembly is arranged at the bottom of the moving square pipe corresponding to the support plug rod. The limit buckling assembly includes a buckling square block, which is fixedly arranged at the bottom of the moving square pipe and corresponds to the connecting block. A sliding long groove is formed at the bottom of the square branch pipe along its length direction, and notch grooves are formed at equal intervals on the two side walls of the sliding long groove.

[0013] The present invention has the following beneficial effects:

[0014] 1. The synchronous belt assembly of the present invention can adjust a plurality of front and rear symmetrically arranged moving square pipes to slide out or retract synchronously in the square branch pipes, and further can adjust the distance between a plurality of symmetrically arranged pneumatic grippers, facilitating clamping of a plurality of vertical rods with different lengths.

And the pushing column is in a fixed state under the cooperation of the adjusting screw rod and the threaded hole, so that it will not cause the cross bar placed on the supporting side plate to be unable to accurately butt with the ends of the plurality of clamped vertical rods due to the rigid connection between the supporting insertion rod and the supporting conduit, which will affect the accurate welding and forming of the isolation guardrail on the welding equipment.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientations or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0036] Please refer to Figures 1-8 As shown, the present invention is a welding device for processing highway isolation guardrails, including a welding frame 1 and a welding machine located on one side of the welding frame 1; a support pipe 2 is installed in the middle of the welding frame 1, and a plurality of square branch pipes 3 are fixedly arranged at equal intervals on both sides of the support pipe 2, and a moving square pipe 4 is slidably inserted into each square branch pipe 3, and a pneumatic finger 41 is arranged on the upper surface of the end of each moving square pipe 4; each moving square pipe 4 is respectively connected to a plurality of groups of synchronous belt assemblies 5 arranged in the support pipe 2; support side plates 6 for positioning and supporting the cross beams of the guardrails are arranged on the front and rear sides of the welding frame 1, and the support side plates 6 are connected to the welding frame 1 through a pushing driving part 7.

[0037] Specifically, the support pipe 2 is horizontally fixedly arranged in the middle of the welding frame 1 from left to right, and a plurality of groups of symmetric square branch pipes 3 are equidistantly installed on the support pipe 2 and communicate with the support pipe 2. The synchronous belt assemblies 5 can adjust the synchronous sliding extension or retraction of a plurality of groups of symmetric moving square pipes 4 in the square branch pipes 3, and further can adjust the distance between a plurality of groups of symmetric pneumatic grippers, so as to facilitate the clamping of a plurality of vertical rods with different lengths. The front and rear symmetric support side plates 6 can position two cross bars, and then through the pushing driving part 7, make them slide and fit towards the plurality of vertically clamped rods, so that the plurality of vertical rods and two cross bars to be welded can be accurately butted. Then, the welding machine equipment on one side of the welding frame 1 can accurately and quickly weld and process the isolation guardrail, and it is not necessary for the operator to manually press and fix the vertical rods and cross bars to be welded, thereby improving the safety and efficiency of the welding of the isolation guardrail. Moreover, the front and rear symmetric support side plates 6 and the pneumatic fingers 41 can both adjust the distance, so that the welding machine equipment of the present invention can weld isolation guardrails with different heights.

[0038] In this embodiment, the synchronous belt assembly 5 includes a shaft rod 51. The shaft rod 51 is rotatably arranged inside the support tube 2 through bearings, and a plurality of driving pulleys 52 are fixedly arranged on the shaft rod 51 at equal intervals. At the outer ends of the two square branch pipes 3 that are symmetrically arranged front and back, driven pulleys 53 are rotatably arranged through the cooperation of a rotating shaft 54 and bearings. A synchronous belt 55 is sleeved between the synchronous belt pulley and the symmetrically arranged driven pulleys 53. The inner end of the moving square tube 4 is in an open shape and is sleeved on the synchronous belt 55. The symmetrically arranged moving square tubes 4 are respectively connected to the upper and lower belt bodies of the synchronous belt pulley through connecting blocks. Support sliding grooves 42 are formed through the left and right side walls of the moving square tube 4. The thickness of the driven pulley 53 is less than the width of the pipe orifice of the square branch pipe 3, so that it is located inside the moving square tube 4. In the cavity formed by the left and right inner side walls of the square branch pipe 3 and the two side walls of the driven pulley 53, rollers 56 are arranged, and the rollers 56 are sleeved on the rotating shaft 54, and the rollers 56 are located in the support sliding grooves 42;

[0039] Preferably, the upper pipe wall of the front moving square tube 4 is connected to the upper belt body of the synchronous belt 55 through a connecting block, and the lower pipe wall of the rear moving square tube 4 is connected to the lower belt body of the synchronous belt 55 through a connecting block. Therefore, when the output shaft of the servo motor fixedly arranged at the end of the support tube 2 drives the shaft rod 51 to rotate, at this time, the cooperation of the plurality of driving pulleys 52 and the driven pulleys 53 causes the synchronous belt 55 extending into the square branch pipe 3 to operate. Furthermore, the synchronous belt 55 will drive the symmetrically arranged moving square tubes 4 to slide in the square branch pipe 3, so as to adjust the distance between the symmetrically arranged pneumatic fingers 41, which is convenient for clamping and fixing vertical rods of different lengths; when the moving square tube 4 slides in the square branch pipe 3, the formed support sliding grooves 42 can avoid sliding past the rotating shaft 54 and the driven pulley 53 located at the pipe orifice of the square branch pipe 3. At the same time, when the moving square tube 4 slides, the rollers 56 on the rotating shaft 54 will be in rolling friction contact with the support sliding grooves 42, which can play a role in gravity support for the sliding moving square tube 4, so that the synchronous belt 55 only plays a role in driving and pushing the moving square tube 4, and will not play a role in gravity bearing for the pushed moving square tube 4. Furthermore, it can prevent the gravity of the vertical rod clamped by the pneumatic finger 41 from directly acting on the synchronous belt 55 through the moving square tube 4, thereby affecting the safe and stable adjustment of the synchronous belt 55 to the moving square tube 4.

[0040] In this embodiment, the pushing and driving part 7 includes a cylinder part 71. Each group of two cylinder parts 71 is fixedly arranged on the inner side surfaces of the left and right cross beams of the welding frame 1. The output rods of the two symmetrically arranged left and right cylinder parts 71 are connected to the support side plate 6. Support guide grooves are symmetrically formed on the left and right two cross beams, and support sliders 72 are slidably arranged in the support guide grooves. The symmetrically arranged left and right support sliders 72 are connected to the same support side plate 6. A right-angle groove 61 is formed on the inner side surface of the support side plate 6. A plurality of support guide pipes 73 are arranged on the back surface of the support side plate 6, and the support guide pipes 73 slide through the front and back cross beams of the welding frame 1;

[0041] Specifically, by driving two sets of four cylinder parts 71 to work, the output shaft drives the support side plate 6 to slide towards the pneumatic finger 41, thereby facilitating the translation of the cross bar placed in the right-angle groove 61 to contact the ends of the multiple vertical bars being clamped, achieving precise contact between the cross bar and the multiple vertical bars. The support sliders 72 on the front and back sides of the support side plate 6 can slide in the support guide grooves, guiding the sliding support side plate 6. The multiple support conduits 73 on the back of the support side plate 6 can slide on the cross beam, providing a gravity support for the support side plate 6 and the placed cross bar, preventing the sliding support side plate 6 from tilting, which would affect the accurate docking contact between the translated cross bar and the multiple clamped vertical bars.

[0042] In this embodiment, a threaded hole is provided in the tail pipe part of the support conduit 73, and a support plug rod 74 is inserted into the pipe orifice near the support side plate 6. A docking socket is provided at the outer end of the moving square pipe 4, and the docking socket corresponds to the support plug rod 74. A push column 75 is arranged in the support conduit 73, and the push column 75 is connected to the support plug rod 74 through a spring member 76. An adjusting screw rod 77 is rotatably connected to the push column 75, and the adjusting screw rod 77 passes through the threaded hole and is located outside the support conduit 73;

[0043] Specifically, when the support side plate 6 slides towards the moving square pipe 4, the end of the support plug rod 74 will be inserted into the docking socket, enabling docking support for the extended moving square pipe 4, further improving the stability and firmness of the moving square pipe 4 in clamping the placed vertical bars. As the support side plate 6 continuously slides closer to the moving square pipe 4, the placed cross bar and the vertical bar are accurately fitted. At this time, the support plug rod 74 will slide relatively into the support conduit 73, and the spring member 76 will be compressed. The push column 75 is fixed under the cooperation of the adjusting screw rod 77 and the threaded hole, so that it will not cause the cross bar placed on the support side plate 6 to be unable to accurately dock with the ends of the multiple clamped vertical bars due to the rigid connection between the support plug rod 74 and the support conduit 73, which would affect the accurate welding and forming of the isolation guardrail on the welding equipment. By twisting the adjusting screw rod 77, the push column 75 slides in the support conduit 73, and then the support plug rod 74 will also slide in the support conduit 73 driven by the spring member 76, facilitating the adjustment of the length of the support plug rod 74 extending outside the support conduit 73 so that it can be accurately aligned and connected with the adjusted moving square pipe 4, further improving the stability and firmness of the moving square pipe 4 in clamping and supporting the vertical bars after sliding.

[0044] In this embodiment, a limit buckling component 8 is provided at the bottom of the moving square pipe 4 corresponding to the support insertion rod 74. The limit buckling component 8 includes a buckling square block 81. The buckling square block 81 is fixedly arranged at the bottom of the moving square pipe 4, and the buckling square block 81 corresponds to the connecting block. A sliding long groove 31 is opened at the bottom of the square branch pipe 3 along its length direction, and notch grooves 32 are equidistantly opened on both side walls of the sliding long groove 31. A conical square hole 811 is opened at the center of the buckling square block 81, and pushing square holes are opened on both side walls of the conical square hole 811. A limit insertion block 82 is slidably arranged in the pushing square hole, and the limit insertion block 82 is slidably inserted and matched with the notch groove 32. A wedge block 83 is inserted into the conical square hole 811, and the wedge block 83 contacts the limit insertion block 82. The outer end of the wedge block 83 is connected with a pushing long rod 84, and the pushing long rod 84 extends to the outer end of the moving square pipe 4;

[0045] A pushing ring 85 is sleeved on the end of the support insertion rod 74, and the pushing ring 85 contacts the end of the pushing long rod 84. The pushing long rod 84 is connected with the moving square pipe 4 through a square sleeve 86. A spring member 76 is sleeved on the pushing long rod 84, and one end of the spring member 76 is connected with the fixed square sleeve 86, and the other end of the spring member 76 is connected with the pushing long rod 84;

[0046] Specifically, when the moving square pipe 4 slides within the square branch pipe 3, the fastening square block 81 at its bottom will also slide synchronously, and the limiting insertion blocks 82 on both sides will correspond to the notch grooves 32. Therefore, when the support insertion rod 74 slides and inserts into the docking socket hole, at this time, the pushing ring 85 will contact the outer end of the pushing long rod 84, and then the pushing long rod 84 will drive the wedge block 83 to slide into the tapered square hole 811. At this time, the spring member 76 on the pushing long rod 84 will be stretched. The sliding of the wedge block 83 within the tapered square hole 811 will push the limiting insertion blocks 82 on both sides, causing them to insert into the notch grooves 32 on both sides. Furthermore, through the plug-in fit of the limiting insertion blocks 82 extending from both sides and the notch grooves 32, the fastening square block 81 can horizontally limit and fix the extended moving square pipe 4, preventing the support side plate 6 from generating a horizontal driving force on the moving square pipe 4 when sliding towards the end of the moving square pipe 4. At this time, under the elastic thrust of the spring member 76 at the inner end, the support insertion rod 74 will generate a horizontal driving force on the moving square pipe 4, which will cause the moving square pipe 4 to generate a horizontal driving force on the synchronous belt 55, resulting in the phenomenon that the synchronous belt 55 rotates within the square branch pipe 3, and further affecting the accurate and stable clamping of the moving square pipe 4 on the vertical rod. When welding the isolation guardrails at the same height, after one end surface of multiple vertical rods is welded to two cross bars and it is necessary to turn them over for welding, at this time, control the symmetrical support side plates 6 to slide away from each other and disengage from the pushing of the two cross bars. At this time, the spring member 76 located within the support conduit 73 will play a role in pushing and positioning the support insertion rod 74, causing it to continue to insert into the docking socket hole. Furthermore, the fastening square block 81 will continue to be in a fixed state through the cooperation of the limiting insertion blocks 82 and the notch grooves 32, enabling the moving square pipe 4 to continue to be in a fixed state. This facilitates the corresponding vertical rods of the turned-over isolation guardrail to accurately fall onto multiple groups of symmetrical cylinder fingers for clamping and fixing, thereby improving the efficiency and accuracy of the welding equipment for welding the isolation guardrails at the same height. When it is necessary to slide and adjust the moving square pipe 4, at this time, the support insertion rod 74 disengages from the docking socket hole, and the pushing long rod 84 will drive the wedge block 83 to slowly disengage from the tapered square hole 811 under the elastic restoring force of the spring member 76, and the limiting insertion blocks 82 will disengage from the notch grooves 32, facilitating the operation of the synchronous belt 55 to drive the symmetrical moving square pipes 4 to slide and extend for adjustment, facilitating the welding process of the isolation guardrails at different heights.

[0047] In this embodiment, a push plate 33 is connected in the notch groove 32 through a spring member 76, and the push plate 33 contacts the end of the limit insertion block 82. Specifically, when the wedge block 83 slowly exits from the tapered square hole 811 and disengages from the extrusion of the limit insertion block 82, at this time, the push plate 33 in the notch groove 32 will push the limit insertion block 82 under the elastic thrust of the spring member 76, so that it can be quickly retracted into the fastening square block 81. When the fastening square block 81 slides, since the push plates 33 in other notch grooves 32 are all located at their notch openings for blocking, therefore, the limit insertion block 82 will not freely slide and get stuck in the notch groove 32, thus affecting the normal sliding work of the moving square pipe 4. When the limit insertion block 82 slides into the notch groove 32, at this time, the push plate 33 will be compressed to the bottom of the notch groove 32, so that it will not interfere with the normal insertion of the limit insertion block 82 into the notch groove 32 to horizontally limit and fix the moving square pipe 4 through the fastening square block 81.

[0048] In this embodiment, a collar 9 is slidably sleeved on the support insertion rod 74, and the inner side surface of the collar 9 is connected to the support side plate 6 through a spring member 76. An outer ring surface of the collar 9 is fixedly provided with a Y-shaped pressing block 91, and the Y-shaped pressing block 91 fits onto the outer side surface of the cross beam placed on the support side plate 6, and the top of the Y-shaped pressing block 91 is provided with an arc-shaped rounded corner. Specifically, the cooperation of the Y-shaped pressing block 91, the bottom collar 9 and the connected spring member 76 can limit and press the cross beam placed in the right-angle groove 61, preventing the phenomenon that the cross beam detaches from the right-angle groove 61 when the support side plate 6 slides. When the support side plate 6 slides away, although the Y-shaped pressing block 91 continues to fit onto the welded cross beam at this time, the collar 9 is elastically connected to the support side plate 6 through the spring member 76. Therefore, it will not interfere with the normal sliding of the support side plate 6 to disengage from the contact with the welded cross beam. And when the welded isolation guardrail is removed from the welding rack 1, at this time, the Y-shaped pressing block 91 will reset under the pulling of the spring member 76. When a new cross bar is placed in the right-angle groove 61, at this time, the Y-shaped pressing block 91 continues to press the cross bar. And when the cross bar contacts the end of the vertical bar, at this time, the "Y" fork of the Y-shaped pressing block 91 will be located on both sides of the vertical bar, and will not interfere with the normal welding process of the vertical bar and the cross bar.
