Description

Technical Field

[0001] The present application relates to the technical field of steel column butt jointing, and in particular to a welding device for steel column butt jointing. Background Art

[0002] In the field of modern construction engineering, steel columns play an indispensable role as key structural support elements and are widely used in various building structures, especially high-rise buildings, large industrial plants, bridges and other projects that have extremely high requirements for structural safety and stability. They are one of the core components to ensure the stability of the entire building structure system.

[0003] In the actual construction process of building projects, due to the constraints of various factors, it is often necessary to carry out steel column docking operations. On the one hand, there are certain limitations on the production length of steel, and it is difficult to directly provide extra-long steel column components that meet the requirements of building design. On the other hand, transportation conditions also restrict the length of steel columns. Overlong steel columns may face many inconveniences during transportation, such as road height restrictions and transportation vehicle size restrictions. This makes it necessary to use segmented steel columns and dock them at the construction site. By accurately docking and welding the pre-buried lower steel column with the upper steel column hoisted to its top, a complete steel column system that meets the requirements of building design height and structural mechanics can be constructed.

[0004] In the related art, the docking of the upper steel column and the lower steel column requires relevant personnel to take a manned lifting platform to the connection between the upper steel column and the lower steel column, and then the relevant personnel operate the welding machine to weld the connection between the upper steel column and the lower steel column to make it a whole. However, this process is highly dependent on manual experience and naked eye judgment. In a high-altitude environment, the operator's field of vision is limited, and it is difficult to accurately assess the degree of deviation and adjustment direction, resulting in low adjustment efficiency. Moreover, high-altitude operations themselves face greater safety risks. During the adjustment process of the docking position, there is also a risk of the upper steel column colliding with relevant personnel, further increasing the possibility of accidents.

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] The welding equipment for butt-jointing steel columns according to an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0025] The welding equipment for connecting steel columns provided in the embodiment of the present application can be used in the process of building construction to assist relevant personnel in connecting the upper steel column with the lower steel column, which can effectively improve the connection efficiency between the upper steel column and the lower steel column, and effectively reduce the deviation of the connection position of the steel columns. At the same time, it can also effectively reduce the possibility of accidents to relevant personnel during the connection process of the steel columns, thereby providing safety protection for relevant personnel during the construction process.

[0026] like Figure 1-Figure 4 As shown, the welding equipment for steel column docking according to the embodiment of the present application may include a base 1, a walking mechanism 2, a lift 3, a support platform 4 and an anti-dumping assembly 5.

[0027] The traveling mechanism 2 is retractable, and is disposed at the bottom of the base 1 , the elevator 3 is disposed on the top of the base 1 , and the supporting platform 4 is disposed on the elevator 3 .

[0028] The anti-dumping assembly 5 may include a clamping mechanism 51 , two limiting slides 52 and a centering positioning mechanism 53 .

[0029] Among them, the clamping mechanism 51 is arranged on the base 1, and the clamping mechanism 51 is used to fix the base 1 on the lower steel column 7. The two limiting slides 52 are respectively arranged on the clamping mechanism 51. The centering positioning mechanism 53 is arranged on the supporting platform 4, and the centering positioning mechanism 53 is respectively mounted on the two limiting slides 52. The centering positioning mechanism 53 is used to center and fix the upper steel column 6 and the lower steel column 7.

[0030] In one embodiment of the present application, the cross-section of the support platform 4 is concave in shape, and one end of a movable platform 401 is pivotally connected to one side of the support platform 4, and the other end of the movable platform 401 is detachably connected to the other side of the support platform 4 by bolts, that is, the top view of the support platform 4 is concave in shape, so that it cooperates with the movable platform 401 to surround the outer periphery of the upper steel column 6 and the lower steel column 7, making it convenient for relevant personnel to perform welding operations around the connection between the upper steel column 6 and the lower steel column 7.

[0031] Specifically, in the process of welding and docking the upper steel column 6 and the lower steel column 7, the relevant personnel first lift the upper steel column 6 to the top of the lower steel column 7 through the external lifting device, and then move the base 1 through the walking mechanism 2 until the support platform 4 is moved to the outer periphery of the lower steel column 7, and fix the other end of the movable platform 401 to the support platform 4 by bolts. At this time, the support platform 4 and the movable platform 401 are sleeved on the outer periphery of the lower steel column 7, and then the relevant personnel clamp and fix the lower steel column 7 by starting the clamping mechanism 51. At this time, the base 1 is limited to one side of the lower steel column 7 to prevent it from shaking, and then the relevant personnel start the elevator 3 to drive the support The supporting platform 4 and the movable platform 401 move upward to the connection between the upper steel column 6 and the lower steel column 7, and then the relevant personnel start the centering positioning mechanism 53 to center the upper steel column 6 and the lower steel column 7 on both sides, and finally reset it, and rotate the base 1 to the other side of the lower steel column 7, and repeat the above steps to center the front and back sides of the upper steel column 6 and the lower steel column 7, thereby effectively improving the docking efficiency of the upper steel column 6 and the lower steel column 7, and effectively reducing the deviation of the steel column docking position, and at the same time, it can also effectively reduce the possibility of accidents to the relevant personnel during the steel column docking process, and provide safety protection for the relevant personnel during the construction process.

[0032] In addition, the base 1 is fixed to the lower steel column 7 by a clamping mechanism 51, and the supporting platform 4 is limited on two limiting slides 52 by a centering positioning mechanism 53, so that the base 1 can be stabilized with the help of the lower steel column 7. On the premise that the lower steel column 7 does not fall over, the possibility of the base 1 falling over is effectively reduced. At this time, relevant personnel can walk on the supporting platform 4 and the movable platform 401, and use a welding machine to weld and fix the four sides of the connection between the upper steel column 6 and the lower steel column 7, so as to realize the docking operation between the upper steel column 6 and the lower steel column 7.

[0033] In one embodiment of the present application, Figure 1-Figure 4 As shown, the traveling mechanism 2 may include four hydraulic cylinders 201 and four universal wheels 202 .

[0034] Among them, four receiving grooves are opened at the bottom of the base 1, and four hydraulic cylinders 201 are respectively arranged in the four receiving grooves, the movable ends of the four hydraulic cylinders 201 are respectively arranged to face downward, and the four universal wheels 202 are respectively fixedly connected to the movable ends of the four hydraulic cylinders 201.

[0035] Specifically, when the base 1 is in a walking state, the four hydraulic cylinders 201 drive the four universal wheels 202 to extend out of the receiving groove, so as to drive the base 1 to move through the four universal wheels 202. When the base 1 is in a fixed state, the four hydraulic cylinders 201 drive the four universal wheels 202 to retract into the receiving groove and make the base 1 contact with the ground, so as to reduce the pressure on the universal wheels 202 and effectively extend their service life.

[0036] In one embodiment of the present application, Figure 1-Figure 4 As shown, the clamping mechanism 51 may include a first mounting frame 511 , two clamping plates 512 , a first motor 513 , a first bidirectional screw rod 514 and a first sliding rod 515 .

[0037] Among them, one side of the base 1 of the first mounting frame 511 is slidably connected up and down, and the first bidirectional screw 514 is rotatably arranged on the first mounting frame 511, the two clamping plates 512 are respectively threadedly connected to the first bidirectional screw 514, and the two clamping plates 512 are respectively threadedly connected to the threaded sections in opposite directions on the first bidirectional screw 514, the first sliding rod 515 is fixedly arranged on the first mounting frame 511, and the two clamping plates 512 are respectively slidably connected to the first sliding rod 515, the first motor 513 is arranged on the first mounting frame 511, and the output shaft of the first motor 513 is coaxially connected to one end of the first bidirectional screw 514 through a coupling.

[0038] Specifically, when limiting the base 1 on the lower steel column 7, the relevant personnel first start the first motor 513 to drive the first bidirectional screw 514 to rotate, so that the two clamping plates 512 move towards each other under the limiting action of the first sliding rod 515, and then the two clamping plates 512 clamp and fix the two sides of the lower steel column 7, thereby achieving the fixation between the base 1 and the lower steel column 7.

[0039] In addition, by connecting the first mounting frame 511 to the base 1 by sliding up and down, after the two clamping plates 512 are fixed to the lower steel column 7, the universal wheel 202 can be retracted into the accommodating groove through the hydraulic cylinder 201, so that the base 1 is directly in contact with the ground, thereby effectively reducing the pressure on the universal wheel 202.

[0040] In one embodiment of the present application, Figure 1-Figure 4 As shown, one end of a shift rod 516 is pivotally connected to one of the clamping plates 512, and the other end of the shift rod 516 is detachably connected to the other clamping plate 512 via bolts.

[0041] Specifically, after the two clamping plates 512 clamp and fix the lower steel column 7, relevant personnel fix the other end of the barrier rod 516 to the other clamping plate 512 through bolts, so that the lower steel column 7 is located between the two clamping plates 512 and the barrier rod 516. Therefore, when the base 1 topples over, even if the two clamping plates 512 and the lower steel column 7 fall off, the base 1 can still be pulled by the barrier rod 516, thereby further reducing the possibility of the base 1 toppling over.

[0042] In one embodiment of the present application, Figure 1-Figure 4 As shown, the two limiting slides 52 are fixedly connected to the two clamping plates 512 respectively, and the bottoms of the two limiting slides 52 are respectively installed with running wheels.

[0043] Specifically, the two limiting slides 52 are in contact with the ground through the running wheels to reduce the pressure effect of the limiting slides 52 on the base 1.

[0044] In one embodiment of the present application, Figure 1-Figure 4 As shown, the centering positioning mechanism 53 may include a second mounting frame 531 , two positioning plates 532 , a second motor 533 , a second bidirectional screw rod 534 and a second sliding rod 535 .

[0045] Among them, the second mounting frame 531 is fixedly set on one side of the supporting platform 4, and the second bidirectional screw 534 is rotatably set on the second mounting frame 531, the two positioning plates 532 are respectively threadedly connected to the second bidirectional screw 534, and the two positioning plates 532 are respectively threadedly connected to the threaded sections in opposite directions on the second bidirectional screw 534, the second sliding rod 535 is fixedly set on the second mounting frame 531, and the two positioning plates 532 are respectively slidably connected to the second sliding rod 535, the two positioning plates 532 are respectively provided with movable grooves, and the two positioning plates 532 are respectively sleeved on the outer periphery of the two limiting slides 52 through the movable grooves, the second motor 533 is set on the second mounting frame 531, and the output shaft of the second motor 533 is coaxially connected to one end of the second bidirectional screw 534 through a coupling.

[0046] Specifically, the relevant personnel start the second motor 533 to drive the second bidirectional screw 534 to rotate, so that the two positioning plates 532 move towards each other under the limiting action of the second sliding rod 535, and then the two sides of the upper steel column 6 and the lower steel column 7 are clamped by the two positioning plates 532 at the connection between the upper steel column 6 and the lower steel column 7, so that the two sides of the upper steel column 6 and the two sides of the lower steel column 7 are in the same straight line, thereby effectively improving the docking efficiency between the upper steel column 6 and the lower steel column 7, and effectively reducing the deviation of the docking position of the steel columns. In addition, the centering positioning mechanism 53, the two limiting slides 52 and the clamping mechanism 51 cooperate with each other to limit the base 1 to the lower steel column 7, so as to fix the base 1 with the stability of being able to contact the lower steel column 7, thereby effectively reducing the possibility of the base 1 tipping over, and then effectively reducing the possibility of accidents to the relevant personnel during the steel column docking process, providing safety protection for the relevant personnel during the construction process.

[0047] In summary, the welding equipment for steel column docking in the embodiment of the present application can effectively improve the docking efficiency of the upper steel column and the lower steel column, and effectively reduce the deviation of the docking position of the steel columns. At the same time, it can also effectively reduce the possibility of accidents to relevant personnel during the steel column docking process, and provide safety protection for relevant personnel during the construction process.
