Description

Technical Field

[0001] This invention relates to the field of bridge steel column welding, and specifically to a steel column free rotation welding device. Background Technology

[0002] Steel column welding is a core process in steel structure engineering. When welding steel columns, there are many welds on the steel columns (especially overhead welds, which are unavoidable). To facilitate the welding work, hoisting equipment is generally used to turn the steel columns over. However, hoisting equipment typically turns the columns 90° at a time. In order to reduce deformation, symmetrical welding is generally required. If conventional methods are used, hoisting equipment needs to be used to turn the columns over continuously. This results in high dependence on hoisting equipment and low utilization of the crane equipment, which not only affects the overall construction efficiency but also increases the complexity of the welding work. Utility Model Content

[0003] This application provides a steel column free rotation welding device, which can solve the technical problem in the prior art that when welding steel columns, the only way to turn them over is by hoisting, which results in a very limited angle of turning over at one time, leading to complicated welding procedures and affecting the overall construction efficiency.

[0004] This application provides a steel column free-rotation welding device, including: The bottom component includes two support mechanisms symmetrically arranged along a first direction. The support mechanism includes a base beam and two support plates spaced apart on top of the base beam along a second direction; A rotating assembly, comprising a rotating wheel located on the top surface of the support plate and an annular ring beam located above the rotating wheel, wherein the central axes of the rotating wheel and the annular ring beam are both arranged along a first direction, and the inner wall of the rotating wheel is provided with a plurality of steel column engaging blocks for engaging with the outer periphery of the steel column to be welded. The first direction is the length direction of the steel column to be welded, and the second direction is the width direction of the steel column to be welded.

[0005] In one embodiment, the base beam is provided with two connecting ears spaced apart along a second direction for connecting the two support plates respectively, and the connecting ears are provided with connecting through holes.

[0006] In one embodiment, the support plate includes two opposing triangular plates, which are respectively located on both sides of the connecting ear.

[0007] In one embodiment, one corner of the triangular plate is used to connect with the connecting lug, and one side of the triangular plate facing the annular ring beam forms a concave arc edge for fitting the annular ring beam.

[0008] In one embodiment, each of the triangular plates is provided with two rotating wheels, and the two rotating wheels are located at both ends of the concave arc edge.

[0009] In one embodiment, two rotating shafts are provided between two opposing triangular plates, and each of the two rotating shafts passes through a rotating wheel.

[0010] In one embodiment, the steel column engaging block includes a fixed triangular block and a steel column welding block located on the outer surface of the fixed triangular block.

[0011] In one embodiment, one side of the fixed triangular block is fixedly connected to the inner ring of the annular beam, and the other two sides of the fixed triangular block are respectively provided with a steel column welding block for welding to the side of the steel column to be welded.

[0012] In one embodiment, the annular beam comprises two opposing and detachable semicircular rings.

[0013] In one embodiment, a limiting wooden wedge is detachably provided between the annular ring beam and the rotating wheel.

[0014] The beneficial effects of the technical solutions provided in this application include: By setting up an annular ring beam for connecting with the steel column to be welded and forming a rolling pair with the rotating wheel, the rotating wheel and the annular ring beam are set coaxially, allowing the steel column to be welded to rotate around its own axis (first direction), which facilitates continuous welding of the annular weld (such as submerged arc welding, gas shielded welding), eliminating the need for frequent adjustments of the steel column posture by the crane, greatly improving welding efficiency, making welding work more convenient, improving welding quality, reducing manual intervention and safety hazards. At the same time, the standardized design of the base beam, support plate and rotating wheel can be reused, reducing the cost of customized equipment. Attached Figure Description

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0019] This application provides a steel column free rotation welding device, which can solve the technical problem in the prior art that when welding steel columns, the only way to turn them over is by hoisting, and the angle of each turn is extremely limited, resulting in a complicated welding process and affecting the overall construction efficiency.

[0020] The steel column free rotation welding device in this application includes a bottom component and a rotating component. The bottom component is used to be stably placed on the ground and serves as the bearing base for the whole device and the steel column 10 to be welded. The rotating component is rotatably mounted on the bottom component and is used to stably connect the steel column 10 to be welded and drive the steel column 10 to be welded to rotate 360 ​​degrees.

[0021] It should be noted that the first direction mentioned in this application refers to the length direction of the steel column 10 to be welded, and the second direction refers to the width direction of the steel column 10 to be welded.

[0022] Specifically, Figure 1 A side view of a steel column free-rotation welding device provided in this application, as shown in the image. Figure 1As shown, the bottom component includes two support mechanisms symmetrically arranged along a first direction. When the steel column 10 to be welded is placed horizontally, it has a certain length. The two support mechanisms are used to support the two ends of the steel column 10 to be welded, so as to ensure that the two ends of the steel column 10 to be welded can rotate simultaneously. The support mechanism includes a base beam 1 and two support plates 2 arranged at intervals on the top of the base beam 1 along a second direction. The base beam 1 is configured as a long rectangular structure and is also arranged along the second direction. In one possible embodiment of this application, in order to ensure the stable overturning of the steel column 10 to be welded, the length of the base beam 1 is greater than the width of the steel column 10 to be welded. Each base beam 1 is provided with two support plates 2 to support the outer circumference of the same end of the steel column 10 to be welded.

[0023] The rotating assembly includes a rotating wheel 3 located on the top surface of the support plate 2 and an annular beam 4 located above the rotating wheel 3. The central axes of the rotating wheel 3 and the annular beam 4 are both set along the first direction. The central axes of the rotating wheel 3 and the annular beam 4 are set perpendicular to the base beam 1 in the horizontal direction. The rotating wheel 3 and the annular beam 4 form a rolling friction pair. The wheel surface material of the rotating wheel 3 must have high wear resistance. When the steel column 10 to be welded is turned over, both of them rotate simultaneously along the second direction.

[0024] The annular ring beam 4 is a ring structure with a diameter greater than the maximum width of the steel column 10 to be welded. During welding, the steel column 10 to be welded passes through the annular ring beam 4. The two annular ring beams 4 respectively clamp and fix the two ends of the steel column 10 to be welded. The outer circumference of the annular ring beam 4 abuts against the wheel surface of the rotating wheel 3. When the annular ring beam 4 rotates by external force, the rotating wheel 3 rotates synchronously.

[0025] The inner wall of the rotating wheel 3 is provided with several steel column engaging blocks 5 for engaging with the outer periphery of the steel column 10 to be welded. The multiple steel column engaging blocks 5 are arranged circumferentially along the inner wall of the rotating wheel 3 and protrude from the inner wall of the rotating wheel 3. The protruding surface of the steel column engaging blocks 5 is adapted to the shape of the outer surface of the steel column 10 to be welded so as to firmly fix the current posture of the steel column 10 to be welded and prevent the steel column 10 to be welded from falling off during the turning process.

[0026] Furthermore, Figure 2 This application provides a schematic diagram of the support plate 2 structure in a steel column free-rotation welding device, as shown below. Figure 2 As shown, the base beam 1 is provided with two connecting ears 6 spaced apart along the second direction for connecting the two support plates 2 respectively. The connecting ears 6 are provided with connecting through holes 7. The connecting ears 6 are key structural components on the base beam 1, mainly used to realize the rigid connection between the base beam 1 and the two support plates 2 on both sides, to ensure the stability of the overall structure and the load transmission efficiency, and to bear the vertical load transmitted from the support plates 2. In this application, the connecting ears 6 are plate-shaped structures, symmetrically welded or integrally formed at both ends of each base beam 1, and the connecting through holes 7 penetrate the connecting ears 6 to facilitate subsequent mechanical connection with the support plates 2.

[0027] Furthermore, the support plate 2 includes two opposing triangular plates 201, which are located on the two sides of the connecting ear 6. One corner of the triangular plate 201 is used to connect with the connecting ear 6 and is fixed to the base beam 1 through the connecting ear 6, so that the support plate 2 can support the annular ring beam 4 and ensure the stability of the overall structure. The corner of the triangular plate 201 connected to the connecting ear 6 is also provided with a through hole for fitting with the above-mentioned connecting through hole 7. The two are mechanically connected by a connecting bolt, which passes through the through holes of the two triangular plates 201 at their opposite positions and the above-mentioned connecting through hole 7, so as to adjust the inclination of the triangular plate 201 according to the diameter of the annular ring beam 4.

[0028] Furthermore, the triangular plate 201 forms a concave arc edge 202 on one side facing the annular ring beam 4 for fitting with the annular ring beam 4. Each triangular plate 201 is provided with two rotating wheels 3, and the two rotating wheels 3 are located at both ends of the concave arc edge 202.

[0029] When the assembly is complete, the triangular plate 201 is in an upside-down state and tilted towards the center of the annular beam 4. The connecting lug 6 and the rotating wheel 3 are both set between the two triangular plates 201. The bottom corner of the triangular plate 201 in the upside-down state is used to connect with the connecting lug 6, and the other two upward-facing corners are used to set a rotating wheel 3 respectively. The side between the two rotating wheels 3 faces the annular beam 4 and forms an inwardly concave arc edge 202 that fits the circumference of the annular beam 4. The triangular plates 201 located at both ends of the base beam 1 respectively abut against the two sides of the circumference of the annular beam 4, ensuring the normal rotation of the annular beam 4 while preventing the annular beam 4 from coming off.

[0030] Furthermore, two rotating shafts 8 are provided between the two opposing triangular plates 201, and each of the two rotating shafts 8 passes through a rotating wheel 3. In conjunction with the above description, each of the three corners of the two triangular plates 201 in each support plate 2 is provided with through holes, one of which is used to connect with the connecting ear 6, and the other two through holes are used to set a rotating shaft 8 to pass through the rotating wheel 3.

[0031] Furthermore, Figure 3 This application provides a schematic diagram of the rotating component structure in a steel column free-rotation welding device, as shown below. Figure 3 As shown, the steel column clamping block 5 includes a fixed triangular block 501 and a steel column welding block 502 located on the outer surface of the fixed triangular block 501. One side of the fixed triangular block 501 is fixedly connected to the inner ring of the annular beam 4, and the other two sides of the fixed triangular block 501 are respectively provided with a steel column welding block 502 for welding to the side of the steel column 10 to be welded.

[0032] The steel column clamping block 5 described above is suitable for square steel columns 10 to be welded. The cross-section of the fixing triangular block 501 is an isosceles triangle structure. The base of this triangle structure is set as an outer arc surface that fits against the inner circumferential wall of the annular beam 4 and forms an integral part with the inner circumferential wall of the annular beam 4. One corner protruding from the inner circumferential wall of the annular beam 4 forms a right angle. Steel column welding blocks 502 are set on the two sides forming this right angle. They are used for the welding points between the annular beam 4 and the outer surface of the steel column 10 to be welded during steel column welding. The axes of the two steel column welding blocks 502 also form The right-angled angle is used to connect the two adjacent sides of the steel column 10 to be welded. In order to ensure a stable connection and uniform force, in one embodiment of this application, the steel column clamping block 5 is set into four groups, corresponding to the four corners of the steel column 10 to be welded. The steel column clamping block 5 is designed by combining the fixed triangular block 501 and the steel column welding block 502. The steel column welding block 502 provides the welding contact surface, realizing the rigid connection between the ring beam 4 and the square steel column. This efficiently solves the problem of irregular connection between the ring beam 4 and the square steel column, and has both positioning accuracy and structural strength.

[0033] Further, see Figure 3 The annular ring beam 4 includes two opposing and detachable semicircular rings 401. The two semicircular rings 401 are box-section beams welded from steel plates, forming a complete annular ring beam 4. When the steel column 10 to be welded is hoisted in, the lower semicircular ring 401 is first welded to the steel column 10, then the upper semicircular ring 401 is hoisted and welded to the steel column 10, and finally the two semicircular rings 401 are connected to form the final shape. There are various ways to connect the two semicircular rings 401. In one possible embodiment of this application, the ends of the two semicircular rings 401 can be connected by sleeves, and then bolts are installed to simultaneously penetrate both semicircular rings 401.

[0034] Further, see Figure 1 A detachable limiting wooden wedge 9 is provided between the annular ring beam 4 and the rotating wheel 3. The limiting wooden wedge 9 has a conical structure, with one end sharp and the other end widened. The sharp end is embedded between the annular ring beam 4 and the rotating wheel 3. In one possible embodiment, the limiting wooden wedge 9 is configured in four sets, which are respectively embedded in the rotating wheels 3 located at both ends of the two base beams 1. As described above, when the steel column 10 to be welded is hoisted in, the annular ring beam 4 is in a state where the two semicircular rings 401 are separated. Since the annular ring beam 4 and the rolling wheel are in surface contact, the semicircular rings 401 may be displaced. The two limiting wooden wedges 9 can limit the semicircular rings 401 on the current base beam 1, which facilitates the subsequent connection work with the steel column 10 to be welded.

[0035] Figure 4 This application provides a top view of a steel column free-rotation welding device, combined with... Figure 4The working mechanism of the free-rotation welding device for steel columns in this application is as follows: Two base beams 1 are placed along the length of the steel column 10 to be welded, and a semi-circular ring 401 is placed on the two rotating wheels 3 on each base beam 1 with the opening of the semi-circular ring 401 facing upward. A limiting wooden wedge 9 is placed to limit the semi-circular ring 401 and hoist the steel column 10 to be welded into the semi-circular ring 401 to perform the connection work between the semi-circular ring 401 and the steel column 10 to be welded. Then, the upper semi-circular ring 401 is hoisted with the opening of the semi-circular ring 401 facing downward to perform the connection work between the semi-circular ring 401 and the steel column 10 to be welded. Finally, the two semi-circular rings 401 are connected to form a whole, and the welding work of the steel column 10 to be welded begins.
