Description

Technical Field

[0001] The invention belongs to the technical field of steel structure construction, in particular to welding equipment for bridge steel structure construction. Background Art

[0002] Bridge steel structure, also known as steel bridge, is a type of bridge whose main load-bearing structure is a rigid frame, and its beams and legs or piers (platforms) form a rigid connection. Due to the characteristics of pier-beam consolidation, the beams and piers are subjected to force as a whole, and the piers not only bear the vertical pressure caused by the load on the beams, but also bear the bending moment and horizontal thrust. Conventional bridge steel structures are mainly completed by steel bar welding, and special welding equipment is required for auxiliary welding.

[0003] Conventional welding equipment is mainly composed of welding machines. When butt welding two steel bars, it is usually necessary to use a clamp to fix the two steel bars and then butt the two steel bars. The butt welding process is completed manually and requires a complex positioning process to achieve accurate butt welding between the two steel bars. The entire operation process is relatively cumbersome.

[0004] At the same time, after welding, in order to perform circumferential welding of the steel bars, the steel bars often need to be rotated to achieve circumferential welding of the steel bars. However, during the rotation process, the two steel bars must rotate synchronously to avoid offset and misalignment, which can easily cause the steel bars to tilt after welding, and improvement is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide a welding device for bridge steel structure construction to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a welding equipment for bridge steel structure construction, comprising two fixed rings, the two fixed rings are symmetrically arranged, the relatively close ends of the two fixed rings are fixedly installed with annular guide rails, the middle part of the top of the fixed ring is fixedly installed with a top plate, the front and rear ends of the middle part of the fixed ring are movably sleeved with movable rods, the relatively far ends of the two movable rods are fixedly installed with movable seats, the relatively close ends of the two movable rods are fixedly installed with clamping rings, the inner side surface of the clamping ring is provided with an anti-slip groove, the top of the top plate is fixedly installed with a limiting assembly, the front and rear sides of the bottom end of the limiting assembly are connected with the movable seat, an annular guide assembly is provided between the two annular guide rails, and the left and right ends of the annular guide assembly are movably clamped with the two annular guide rails.

[0007] When two steel bars need to be welded and butted, the two fixing rings can be respectively sleeved on the outer sides of the two steel bars, and the two fixing rings are symmetrically arranged to complete the preparation before welding the two steel bars.

[0008] As a further technical solution of the present invention, the limit assembly includes a mounting seat, an electric push rod is provided below the mounting seat, the bottom end of the electric push rod is connected to the top end of the top plate, and the output end of the electric push rod is connected to the middle part of the bottom end of the mounting seat.

[0009] As a further technical solution of the present invention, a first fixed seat is fixedly installed on both sides of the left and right sides of the bottom end of the mounting seat, the end of the first fixed seat away from the mounting seat is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0010] As a further technical solution of the present invention, a clamping seat is fixedly installed in the middle of the top end of the mounting seat, and the bottom end of the second fixed seat is connected to the middle of the top end of the movable seat.

[0011] When the preparation is completed, the steel bar is located between the two clamping rings. At this time, the electric push rod can be turned on and controlled to extend. At this time, the mounting seat moves upward, and the two connecting rods at the bottom of the mounting seat deflect toward the middle of the mounting seat, while applying thrust to the two movable seats at the bottom.

[0012] As a further technical solution of the present invention, inner side surfaces of the two clamping seats are movably clamped with clamping columns, and a telescopic rod is fixedly connected between the two clamping columns.

[0013] When the movable seats are both pushed inward, the two movable seats are relatively close to each other, and drive the movable rod and the clamping ring to be relatively close to each other. When the two clamping rings are relatively close to each other, they can gradually contact the outer side surface of the steel bar until the clamping ring contacts the outer side surface of the steel bar. At this time, the process of limiting and fixing the steel bar can be completed. At the same time, since the two fixed rings are symmetrically arranged, when the limiting and fixing is completed, the two steel bars also complete the positioning process. After the positioning is completed, the telescopic rod can be controlled to shorten by opening the telescopic rod. At this time, the two clamping seats are relatively close to each other, and drive the two mounting seats to be relatively close to each other. At this time, the two fixed rings can be pulled relatively close, and the two steel bars can be pulled relatively close until the two steel bars touch head to tail, and the docking process of the two steel bars can be completed.

[0014] By providing two fixing rings and arranging them symmetrically, and connecting the two fixing rings with a telescopic rod, the two movable seats can be quickly brought close to each other through the linkage between the limit assembly and the movable seat, and the steel bars can be quickly fixed through the clamping ring. The whole process is completed quickly, and fast and accurate docking can be achieved without the need for a complicated positioning process, which effectively simplifies the operating steps and improves the overall processing efficiency.

[0015] As a further technical solution of the present invention, the annular guide assembly includes two symmetrically arranged annular guide blocks, which are movably connected to two annular guide rails respectively, and the relatively close ends of the two annular guide blocks are fixedly connected to the limiting rod.

[0016] As a further technical solution of the present invention, the annular guide assembly includes a fixed tube, and limit plates are movably sleeved on both sides of the inner cavity of the fixed tube, and the relatively distant ends of the two limit plates are fixedly connected to the limit rod.

[0017] As a further technical solution of the present invention, an operating plate is fixedly sleeved on one end of the outer side surface of the limit rod located on the outer side surface of the fixed tube, and a limit spring is movably sleeved on the outer side surface of the limit rod. The left and right ends of the limit spring are respectively connected to one end of the inner cavity of the fixed tube and one end of the limit plate.

[0018] As a further technical solution of the present invention, a fixing block is fixedly sleeved on the middle portion of the outer side surface of the fixing tube, and a welding machine is fixedly connected to the bottom end of the fixing block.

[0019] When the welding positioning between the two steel bars is completed, the annular guide assembly is located on the outer side surface between the two steel bars. At the same time, when the telescopic rod is shortened, the two limit plates are relatively close to each other and displaced relative to the fixed tube, and the limit spring is stretched until the two annular guide blocks are relatively close to each other, completing the synchronous adjustment of the spacing between the two annular guide blocks. After the adjustment is completed, the fixed block is just located on the outer side surface of the contact point between the two steel bars. At this time, the fixed block can be pulled to make the two annular guide blocks rotate relative to the annular guide rail. At this time, the welding machine can rotate circumferentially relative to the steel bars. At this time, the welding machine can be turned on to quickly weld the two steel bars until a circle of welding is completed.

[0020] After the welding positioning between the two steel bars is achieved through the two limit assemblies, the overall length of the annular guide assembly can be quickly adjusted through the telescopic rod. At the same time, the circumferential rotation of the welding machine can be quickly achieved through the clamping positioning between the annular guide assembly and the two annular guide rails, and the rapid welding of the two steel bars after welding positioning is completed. At the same time, circumferential welding can be achieved, and the two steel bars are in a precise docking state during the entire welding process, which can significantly improve the welding efficiency, while avoiding the problem of easy offset of traditional devices during welding, thereby improving the welding quality.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention provides two fixed rings and sets them symmetrically. The two fixed rings are connected by a telescopic rod. The two movable seats can be quickly brought close to each other through the linkage between the limit assembly and the movable seat. The steel bars can be quickly fixed through the clamping ring. The whole process is completed quickly, and fast and accurate docking can be achieved without complicated positioning process. The operation steps are effectively simplified and the overall processing efficiency is improved.

[0022] (2) After the present invention realizes the welding positioning between the two steel bars by means of two limit assemblies, the overall length of the annular guide assembly can be quickly adjusted by means of a telescopic rod. At the same time, the circumferential rotation of the welding machine can be quickly realized by means of the clamping positioning between the annular guide assembly and the two annular guide rails, so that the two steel bars can be quickly welded after the welding positioning is completed. At the same time, circumferential welding can be realized, and the two steel bars are in a precisely docked state during the entire welding process, which can significantly improve the welding efficiency and avoid the problem of displacement that is easy to occur in traditional devices during welding, thereby improving the welding quality.

[0027] When two steel bars need to be welded together, the two fixing rings 1 can be respectively sleeved on the outer sides of the two steel bars, and the two fixing rings 1 are symmetrically arranged to complete the preparation before welding the two steel bars.

[0028] like Figure 1 and Figure 3 As shown, the limit assembly 6 includes a mounting seat 601, and an electric push rod 606 is provided below the mounting seat 601. The bottom end of the electric push rod 606 is connected to the top of the top plate 2, and the output end of the electric push rod 606 is connected to the middle part of the bottom end of the mounting seat 601. The left and right sides of the bottom end of the mounting seat 601 are fixedly installed with a first fixed seat 602, and the end of the first fixed seat 602 away from the mounting seat 601 is movably connected to a connecting rod 604 through a rotating shaft, and the end of the connecting rod 604 away from the first fixed seat 602 is movably connected to a second fixed seat 603 through a rotating shaft, and a clamping seat 605 is fixedly installed in the middle part of the top end of the mounting seat 601, and the bottom end of the second fixed seat 603 is connected to the middle part of the top end of the movable seat 3.

[0029] When the preparation is completed, the steel bar is located between the two clamping rings 5. At this time, the electric push rod 606 can be turned on and controlled to extend. At this time, the mounting seat 601 moves upward, and the two connecting rods 604 at the bottom of the mounting seat 601 deflect accordingly, that is, deflect toward the middle of the mounting seat 601, and at the same time, thrust is applied to the two movable seats 3 at the bottom.

[0030] like Figure 1 and Figure 3 as well as Figure 4 As shown, the inner side surfaces of the two clamping seats 605 are movably clamped with clamping columns 7 , and a telescopic rod 8 is fixedly connected between the two clamping columns 7 .

[0031] Embodiment: When the movable seats 3 are both pushed inward, the two movable seats 3 are relatively close to each other, and drive the movable rod 4 and the clamping ring 5 to be relatively close to each other. When the two clamping rings 5 ​​are relatively close to each other, they can gradually contact the outer side surface of the steel bar until the clamping ring 5 contacts the outer side surface of the steel bar. At this time, the process of limiting and fixing the steel bar can be completed. At the same time, since the two fixed rings 1 are symmetrically arranged, when the limiting and fixing is completed, the two steel bars also complete the positioning process. After the positioning is completed, the telescopic rod 8 can be controlled to shorten by opening the telescopic rod 8. At this time, the two clamping seats 605 are relatively close to each other, and drive the two mounting seats 601 to be relatively close to each other. At this time, the two fixed rings 1 can be pulled relatively close, and the two steel bars can be pulled relatively close until the two steel bars are in contact end to end, and the docking process of the two steel bars can be completed.

[0032] By providing two fixing rings 1 and arranging them symmetrically, and connecting the two fixing rings 1 with a telescopic rod 8, the two movable seats 3 can be quickly brought into relative proximity through the linkage between the limit assembly 6 and the movable seat 3, and the steel bars can be quickly fixed through the clamping ring 5. The whole process is completed quickly, and fast and accurate docking can be achieved without the need for a complicated positioning process, which effectively simplifies the operation steps and improves the overall processing efficiency.

[0033] like Figure 1 and Figure 3 as well as Figure 5 and Figure 6 As shown, the annular guide assembly 10 includes two symmetrically arranged annular guide blocks 101, which are movably connected to the two annular guide rails 9 respectively, and the relatively close ends of the two annular guide blocks 101 are fixedly connected to the limiting rod 103. The annular guide assembly 10 includes a fixed tube 102, and the left and right sides of the inner cavity of the fixed tube 102 are movably sleeved with limiting plates 104, and the relatively far ends of the two limiting plates 104 are fixedly connected to the limiting rod 103. The outer side surface of the limiting rod 103 is located at one end of the outer side surface of the fixed tube 102 and is fixedly sleeved with an operating plate 106. The outer side surface of the limiting rod 103 is movably sleeved with a limiting spring 105, and the left and right ends of the limiting spring 105 are respectively connected to one end of the inner cavity of the fixed tube 102 and one end of the limiting plate 104, and the middle part of the outer side surface of the fixed tube 102 is fixedly sleeved with a fixed block 11, and the bottom end of the fixed block 11 is fixedly connected with a welding machine 12.

[0034] Embodiment: After the welding positioning between the two steel bars is completed, the annular guide assembly 10 is located on the outer side surface between the two steel bars. At the same time, when the telescopic rod 8 is shortened, the two limit plates 104 are relatively close to each other and displaced relative to the fixed tube 102, and the limit spring 105 is stretched until the two annular guide blocks 101 are relatively close to each other, and the synchronous adjustment of the spacing between the two annular guide blocks 101 is completed. After the adjustment is completed, the fixed block 11 is just located on the outer side surface of the contact point between the two steel bars. At this time, the fixed block 11 can be pulled to make the two annular guide blocks 101 rotate relative to the annular guide rail 9. At this time, the welding machine 12 can rotate circumferentially relative to the steel bars. At this time, turning on the welding machine 12 can quickly weld the two steel bars until a circle of welding is completed.

[0035] After the welding positioning between the two steel bars is achieved through the two limit assemblies 6, the overall length of the annular guide assembly 10 can be quickly adjusted through the telescopic rod 8. At the same time, the circumferential rotation of the welding machine 12 can be quickly achieved through the clamping positioning between the annular guide assembly 10 and the two annular guide rails 9, and the rapid welding of the two steel bars after welding positioning is completed. At the same time, circumferential welding can be achieved, and the two steel bars are in a precise docking state during the entire welding process, which can significantly improve the welding efficiency, while avoiding the problem of easy offset of traditional devices during welding, thereby improving the welding quality.

[0036] Working principle and usage process: When two steel bars need to be welded together, the two fixing rings 1 can be respectively sleeved on the outer sides of the two steel bars, and the two fixing rings 1 are symmetrically arranged to complete the preparation before welding the two steel bars; When the preparation is completed, the steel bar is located between the two clamping rings 5, and the electric push rod 606 can be turned on and controlled to extend. At this time, the mounting seat 601 moves upward, and the two connecting rods 604 at the bottom of the mounting seat 601 deflect toward the middle of the mounting seat 601, and at the same time, a thrust is applied to the two movable seats 3 at the bottom. When the movable seats 3 are both pushed inward, the two movable seats 3 are relatively close to each other, and drive the movable rod 4 and the clamping ring 5 to be relatively close to each other. When the two clamping rings 5 ​​are relatively close to each other, they can gradually contact the outer side surface of the steel bar until the clamping ring 5 contacts the outer side surface of the steel bar. At this time, the process of limiting and fixing the steel bar can be completed. At the same time, since the two fixing rings 1 are symmetrically arranged, when the limiting and fixing is completed, the two steel bars also complete the positioning process. After the positioning is completed, the telescopic rod 8 can be controlled to shorten by opening the telescopic rod 8. At this time, the two clamping seats 605 are relatively close to each other, and drive the two mounting seats 601 to be relatively close to each other. At this time, the two fixing rings 1 can be pulled relatively close, and the two steel bars can be pulled relatively close until the two steel bars are in contact head to tail, and the docking process of the two steel bars can be completed. After the welding positioning between the two steel bars is completed, the annular guide assembly 10 is located on the outer side surface between the two steel bars.

After the adjustment is completed, the fixed block 11 is just located on the outer side surface of the contact point between the two steel bars. At this time, the fixed block 11 can be pulled to make the two annular guide blocks 101 rotate relative to the annular guide rail 9. At this time, the welding machine 12 can rotate circumferentially relative to the steel bars. At this time, turning on the welding machine 12 can quickly weld the two steel bars until a circle of welding is completed.
