Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure assembly, in particular to a steel structure butt joint device and method for steel structure construction. BACKGROUND

[0002] The steel structure butt joint in steel structure construction refers to the process of realizing seamless connection of the end of two or more independent steel members (such as beams, columns, trusses, etc.) in the length direction or spatial position through precise positioning, temporary fixing, and welding or bolt connection processes, forming a continuous and stable overall structure. The core lies in controlling the flatness, perpendicularity, gap size, and misalignment of the butt joint surface, etc. parameters to ensure that the connection node meets the design requirements of mechanical properties (such as shear resistance, bending resistance, fatigue resistance) and construction specifications, which is the key link to ensure the overall stability, bearing capacity, and construction accuracy of the steel structure. In order to realize the rapid positioning of the steel structure in the complex construction environment, the existing steel structure butt joint device for steel structure construction is designed by modularization, high-precision adjustment mechanism, and intelligent control technology. From traditional mechanical adjustment to hydraulic / electric drive, it can more flexibly and quickly complete the butt joint of the steel structure, realize the precise positioning, stable support, and efficient welding of the steel structure. However, when the existing steel structure butt joint device is used for clamping and butt joint of the steel structure, in order to keep the consistent matching direction of the corresponding clamping mechanism during positioning adjustment, the whole butt joint structure is mostly fixed on the same main frame. Therefore, when the size of the steel structure to be butt jointed is large, a large-scale structure such as a gantry is needed to complete the splicing, which requires a lot of manpower and material resources to build and install the large-scale support in the actual construction process.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0027] In the description of the present application, it is understood that the meaning of "a plurality of" is two or more than two, unless otherwise explicitly and specifically limited.

[0028] Please refer to Figures 1 to 8The application provides a steel structure butt joint device and method for steel structure construction, which comprises a pulley support 101, a supporting frame 102, a screw supporting mechanism 103 and a butt joint assembly, the butt joint assembly comprises a lifting frame 104, a side adjusting frame 105, a truss 106, a connecting support 107, a position adjusting member, an alignment member and a clamping member, the position adjusting member comprises a mounting frame 201, a rotating frame 202, a rotating motor 203, a turnover mechanism 204 and a control part, the alignment member comprises an inclination sensor 301, a shooting box 302, a shooting device 303 and a connecting part, the clamping member comprises a sliding frame 401, a screw sliding mechanism 402, a connecting support 403 and a bidirectional adjusting mechanism 404, the control part comprises a screw lifting mechanism 501, a screw unfolding mechanism 502 and a screw moving mechanism 503, the connecting part comprises a winding mechanism 601, a wire 602 and a wire drum 603, the clamping member further comprises a downward moving support 405, a downward moving cylinder 406, a rotating adjusting mechanism 408 and a clamping device 409, and the connecting part further comprises a supporting table 604, a pressing table 605 and a pressing cylinder 606, through the foregoing scheme, the problem that, in the prior art, when the clamping butt joint of the steel structure is performed, in order to keep the consistent matching direction of the corresponding clamping mechanism during the position adjusting, the whole butt joint structure is mostly fixed on the same main frame, so when the size of the steel structure to be butt jointed is large, a large structure such as a gantry is needed to complete the splicing, which causes the need to spend large manpower and material resources to build and install the large support in the actual construction process, and when the steel structures of different lengths are butt jointed, a large frame structure of the corresponding size needs to be designed in advance, which leads to the problem that the adjustable range of the whole butt joint device is very limited and cannot be greatly adjusted and changed according to the actual size of the steel structure during the actual butt joint operation.

[0029] Further, the supporting frame 102 is slidingly installed on the pulley support 101, the screw supporting mechanism 103 is connected with the pulley support 101 and is used for driving the supporting frame 102, the lifting frame 104 is slidingly installed on the pulley support 101, the side adjusting frames 105 are slidingly installed on the two sides of the truss 106, the two side adjusting frames 105 are rotationally connected with the lifting frames 104 arranged on the two sides respectively, the connecting support 107 is connected with the truss 106 through the position adjusting member and is used for adjusting the butt joint direction of the device, the alignment member is connected with the connecting support 107 and is used for judging the matching position of the connecting support 107, and the clamping member is connected with the connecting support 107 and is used for clamping the corresponding steel structure.

[0030] Specifically, the bottom of the pulley support 101 is provided with universal wheels, and the pulley support 101, the side adjusting frame 105 and the truss 106 erected in the middle form a movable gantry structure, and the side adjusting frame 105 on both sides can also change the lateral span of the entire gantry structure by sliding on the truss 106, so that the operator can adjust the entire frame structure according to the actual construction site and the shape and size of the steel structure to be matched.

[0031] Each pulley support 101 is provided with the supporting frame 102 and the lead screw supporting mechanism 103, which is composed of a lead screw and a motor driving the lead screw to rotate. The motor drives the lead screw to rotate, thereby driving the corresponding frame to move. The gantry structure composed of two groups of pulley supports 101 and related mechanisms can be supported by moving the supporting frame 102 on the pulley support 101, avoiding the sliding of the universal wheels at the bottom of the pulley support 101 during subsequent clamping and docking of the steel structure, and ensuring the stability of subsequent operations.

[0032] In actual operation, the universal wheels at the bottom of the pulley support 101 drive the corresponding docking assembly to move, so that the two independent docking assemblies are matched with the two steel structures to be docked. Based on the actual size of the steel structure, the erection span of the corresponding docking assembly is adjusted by the movement of the side adjusting frame 105 on the truss 106 through the adjusting member, and then the supporting frame 102 on the pulley support 101 is lowered by the lead screw supporting mechanism 103, thereby supporting the corresponding docking assembly. The alignment member installed on the connecting bracket 107 cooperates with the lifting frame 104 sliding on the corresponding pulley support 101 and the adjusting member to horizontally calibrate the corresponding docking assembly. After the two docking assemblies on both sides are adjusted to the horizontal state, the positioning and calibration of the two docking assemblies can be completed through the alignment member and the adjusting member. After the positioning and calibration of the two docking assemblies are completed, the corresponding steel structure can be clamped by the clamping member, and then the docking of the two steel structures is completed, which realizes the docking of the two steel structures by setting two groups of clamping mechanisms matched with each other, and then adjusting and adapting the entire docking device according to the size of the steel structure to be docked through the corresponding positioning structure and adjusting structure, so as to quickly and flexibly complete the docking of large-size steel structures.

[0033] Further, the mounting frame 201 is slidingly mounted on the truss 106; the rotating frame 202 is rotatably connected with the connecting support 107 and rotatably mounted on the mounting frame 201; the output shaft of the rotating motor 203 is connected with the rotating frame 202, and the rotating motor 203 is fixedly mounted on the mounting frame 201; the turnover mechanism 204 is mounted on the rotating frame 202 and used for driving the connecting support 107; the control component is connected with the lifting frame 104 and used for adjusting the position of the corresponding frame body.

[0034] Further, the screw rod lifting mechanism 501 is connected with the pulley support 101 and used for driving the lifting frame 104; the screw rod unfolding mechanism 502 is connected with the truss 106 and used for driving the side adjusting frame 105; the screw rod moving mechanism 503 is connected with the truss 106 and used for driving the mounting frame 201.

[0035] In use, the mounting frame 201 is slidingly mounted on the truss 106, the rotating frame 202 is rotatably mounted on the mounting frame 201, and the connecting support 107 is rotatably mounted on the rotating frame 202; the rotating frame 202 is driven by the rotating motor 203, and the connecting support 107 is driven by the turnover mechanism 204.

[0036] The screw rod lifting mechanism 501 and the screw rod moving mechanism 503 have the same structure principle as the screw rod supporting mechanism 103, that is, the driving of the corresponding plate is completed by the rotation of the screw rod; the screw rod lifting mechanism 501 is used for driving the lifting frame 104 on the pulley support 101 to move up and down, and the screw rod moving mechanism 503 is used for driving the mounting frame 201 to move left and right on the truss 106; the screw rod unfolding mechanism 502 is composed of two screw rods with opposite screw directions and driving elements for driving the screw rods to rotate; the side adjusting frames 105 on both sides of the truss 106 are matched with the two sides of the screw rods of the screw rod unfolding mechanism 502; when the screw rods of the screw rod unfolding mechanism 502 rotate, the two side adjusting frames 105 can move towards the two sides on the truss 106, thereby adjusting the support span of the pulley support 101.

[0037] The lifting frame 104 is rotationally connected with the side adjusting frame 105. Since the side adjusting frames 105 and the pulley supports 101 on both sides of the truss 106 can not be in the same horizontal plane during the butt joint installation on the construction site, when the pulley supports 101 on both sides are supported by the supporting frames 102, the truss 106 can be in an inclined state. Therefore, the height of the lifting frames 104 on both sides can be adjusted to cooperate with the position adjustment of the side adjusting frames 105, so that the truss 106 is in a horizontal state, thereby facilitating the subsequent quick positioning and cooperation during the clamping and butt joint of the steel structure.

[0038] The mounting frame 201 can be moved on the truss 106 to adjust the fitting position of the connecting bracket 107. The rotating frame 202 can be rotated on the mounting frame 201 to adjust the fitting angle of the connecting bracket 107. Since the two steel structures to be butt jointed are clamped by two groups of pulley supports 101 and their corresponding structures, the connecting brackets 107 of the two groups of structures are not in the same horizontal plane after the gantry structure composed of the two groups of pulley supports 101 is positioned and supported. Therefore, the two connecting brackets 107 of the two groups of structures can be adjusted by moving the mounting frame 201 left and right, rotating the rotating frame 202, rotating the connecting bracket 107, and moving the lifting frame 104 up and down, so that the connecting brackets 107 on both sides can be located in the same horizontal plane, thereby facilitating the subsequent driving and cooperation of the two clamped steel structures.

[0039] Further, the inclination sensor 301 is installed on the side adjusting frame 105; the shooting box 302 is installed on the connecting bracket 107; the shooting device 303 is installed in the shooting box 302; the connecting component is connected with the connecting bracket 107, and is used for judging the fitting state of the connecting bracket 107 in cooperation with the shooting device 303.

[0040] Further, the wire winding mechanism 601 is installed on one side of the shooting box 302; the wire 602 is connected with the wire winding mechanism 601 and penetrates out of the shooting box 302; and the wire guide cylinder 603 is fixedly installed on the side of the connecting bracket 107 away from the shooting box 302.

[0041] Further, the support table 604 is fixedly installed on the side of the connecting bracket 107 close to the wire guide cylinder 603; the pressing table 605 is slidingly installed on the side of the connecting bracket 107 close to the support table 604; the output shaft of the pressing cylinder 606 is connected with the pressing table 605, and the pressing cylinder 606 is fixedly installed on one side of the connecting bracket 107.

[0042] In use, the inclination sensor 301 is fixedly installed on the side adjusting frame 105, and the inclination sensor 301 realizes angle measurement by detecting the included angle between the gravitational acceleration and the sensitive axis of the sensor. In this way, the operator can measure the inclination angle of the side adjusting frame 105 and the truss 106 through the inclination sensor 301, and then drive the lifting frame 104 on the designated side according to the measurement result, so that the side adjusting frame 105 and the truss 106 can be in a horizontal state, facilitating the subsequent calibration and positioning of the two groups of pulley supports 101 and the docking assembly, and also enabling more accurate and convenient position adjustment of the clamped steel structure.

[0043] The shooting box 302 and the shooting device 303 are arranged on one side of the connecting support 107, and the support table 604, the pressing table 605 and the pressing cylinder 606 are arranged on the other side of the connecting support 107. The winding mechanism 601 and the wire 602 are arranged on the rear side of the shooting box 302, and the wire guide cylinder 603 is fixed on the side of the pressing table 605. The guide hole of the wire guide cylinder 603 is matched with the wire 602, and an outwardly expanding inclined surface is arranged on the outer side of the wire guide cylinder 603, so that the operator can more easily pass the wire 602 through the guide hole of the wire guide cylinder 603.

[0044] The wire 602 is installed on the winding mechanism 601, and the wire outlet of the winding mechanism 601 is coincided with the center of the box body of the shooting box 302. Two groups of shooting modules for top shooting and side shooting are arranged in the shooting box 302.

[0045] When the two groups of gantry structure composed of the pulley support 101 and its corresponding mechanism are erected by the operator, the wire 602 led out by the winding mechanism 601 of one group of gantry structure can enter the pressing table 605 of the other group of gantry structure through the wire drum 603 of the other group of gantry structure, and then the wire 602 on the pressing table 605 is pressed and fixed by the corresponding pressing cylinder 606 and the supporting table 604, and then the winding mechanism 601 of the corresponding gantry structure can be operated to make the wire 602 tight. If the connecting supports 107 on both sides are not in the same horizontal state at this time, the wire 602 in the shooting box 302 will be bent by a corresponding amplitude, and then the shooting device 303 in the shooting box 302 shoots the state of the wire 602 in the shooting box 302 from two horizontal directions, and then the offset path and the offset angle of the wire 602 in the shooting box 302 are determined, and finally the two connecting supports 107 are adjusted based on the offset path and the offset angle, so as to realize the positioning and calibration of the two connecting supports 107. When the wire 602 in the shooting box 302 is in a horizontal state, the two connecting supports 107 will also be in the same horizontal direction at this time, so that after the corresponding steel structure is clamped, the two steel structures can be quickly adjusted and positioned based on the determined reference and the steel structure size and cooperation requirements, so that the two steel structures are connected more quickly and accurately.

[0046] Further, the sliding frame 401 is slidingly installed on the connecting support 107; the screw sliding mechanism 402 is connected with the connecting support 107 and is used to drive the sliding frame 401; two connection supports 403 are respectively slidingly installed on both sides of the sliding frame 401; the bidirectional adjustment mechanism 404 is connected with the sliding frame 401 and is used to drive the two connection supports 403.

[0047] Further, the downward moving support 405 is slidingly installed on the connection support 403; the output end of the downward moving cylinder 406 is connected with the downward moving support 405, and the downward moving cylinder 406 is fixedly installed on the downward moving support 405; the index frame 407 is rotatably installed on the downward moving support 405; the index adjustment mechanism 408 is connected with the downward moving support 405 and is used to drive the index frame 407; the clamping device 409 is installed on one side of the index frame 407.

[0048] In use, the connecting support 107 is slidably installed at the bottom of the sliding frame 401, the sliding frame 401 is driven by the lead screw sliding mechanism 402, the lead screw sliding mechanism 402 has the same structure as the lead screw supporting mechanism 103, the connecting supports 403 are slidably installed on both sides of the sliding frame 401, the connecting supports 403 are driven by the bidirectional adjusting mechanism 404, the bidirectional adjusting mechanism 404 is connected with the sliding frame 401, the bidirectional adjusting mechanism 404 has the same structure as the lead screw unfolding mechanism 502, and both are driven by corresponding driving elements through two screw rods with opposite screw directions on both sides.

[0049] The lower moving support 405 is slidably installed below the connecting support 403, the lower moving support 405 is driven by the lower moving cylinder 406, the rotary support 407 is rotatably installed below the lower moving support 405, the rotary support 407 is driven by the rotary adjusting mechanism 408, the rotary adjusting mechanism 408 has the same structure as the overturning mechanism 204, and the clamping devices 409 are installed on both sides of the rotary support 407, the clamping devices 409 are pneumatic clamping jaws, and the steel structure placed on the ground can be clamped by the clamping devices 409, so that the position and height of the clamped steel structure can be adjusted by cooperating with the movement of the corresponding frame body.

[0050] For steel structures of different lengths, the positions of the connecting supports 403 on both sides can be adjusted to ensure the stability of the clamped steel structure, so as to avoid the situation that the center of gravity of the clamped steel structure deviates, and the rotary supports 407 and the clamping devices 409 can clamp the steel structure at multiple points, further ensuring the stability of the clamped steel structure, and when two small steel structures are butt-jointed, the two connecting supports 403 on the same sliding frame 401 and the corresponding clamping structures arranged on the two connecting supports 403 can clamp the two steel structures, and then the movement of the two connecting supports 403 on the sliding frame 401 can complete the butt-joint of the two small steel structures, so that more types of steel structures can be butt-jointed.

[0051] Preferably, the butt-joint assembly further comprises an ejection frame 701, an ejection spring 702 and an infrared range finder 703.

[0052] Further, two said ejection frames 701 are slidingly installed on each said index frame 407; two said ejection springs 702 are installed in said index frame 407 and respectively matched with two said ejection frames 701; two groups of said infrared range finders 703 are installed on said index frame 407, and two groups of said infrared range finders 703 are respectively matched with two said ejection frames 701.

[0053] In use, the index frame 407 is provided with two groups of said ejection frames 701 and said ejection springs 702, each said ejection frame 701 is provided with a corresponding said infrared range finder 703 for monitoring, and the set said infrared range finder 703 can detect and record the extension distance of the corresponding said ejection frame 701.

[0054] Because the clamping device 409 provided on the index frame 407 may be inclined when clamping the steel structure, if the index frame 407 is vertically lowered for clamping, the clamped steel structure will be offset relative to the index frame 407, resulting in deviation when adjusting the butt joint position and angle of the steel structure, therefore, the two groups of said ejection frames 701 provided on the index frame 407 cooperate with the ejection spring 702 to judge the angle difference between the steel structure surface and the index frame 407 in advance, the specific judgment method is that the corresponding index frame 407 is first vertically lowered, after the two groups of said ejection frames 701 at the bottom of the index frame 407 contact the steel structure surface, the ejection frame 701 will continuously retract due to the extrusion of the steel structure, thereby extruding the ejection spring 702 to shrink, when the bottom surface of the index frame 407 is parallel to the corresponding steel structure surface, the retraction distances of the two said ejection frames 701 will be the same, and when the corresponding steel structure surface is offset, the retraction distances of the two said ejection frames 701 will be different, then according to the difference in retraction distance, the offset direction of the corresponding steel structure surface can be judged, so that the generated angle difference can be eliminated by rotating the index frame 407 through the index adjustment mechanism 408.
