Description

Technical Field

[0001] The present application relates to the technical field of steel structure construction, and in particular to a device and method for assisting steel structure welding. Background Art

[0002] During the construction of steel structure buildings, since welding at high altitudes is very dangerous, unless necessary, steel components are generally pre-welded on the ground, and then the pre-welded components are hoisted to a specific location by a crane or tower crane to complete the positioning and installation of the steel structure.

[0003] At present, in some complex high-rise building structural systems, steel corridor structures are used, that is, two or more high-rise buildings are connected by an overhead connector (i.e. corridor). When assembling a steel corridor, a frame is usually set up on the ground, and then the lower chord and upper chord are hoisted to the frame by a tower crane. When they are at a certain distance from the frame, the positions of the upper and lower chords are manually adjusted to align them, and then the tower crane is lowered to place the upper and lower chords on the frame, and welders go to the welding points for welding.

[0004] When using relevant technologies for splicing and welding, it is difficult to accurately control the accuracy by manual control. However, since the steel structures are welded (i.e. fixedly connected), very high accuracy requirements are required, and the tower crane is always occupied during the manual adjustment of the position, affecting construction efficiency. Summary of the invention

[0005] In order to reduce the positioning error before welding of steel components, the present application provides a device and method for assisting steel structure welding.

[0006] In a first aspect, the present application provides a device for assisting steel structure welding, which adopts the following technical solution: a device and method for assisting steel structure welding, comprising a tire frame unit, wherein the tire frame unit comprises four tire frames, wherein the four tire frames comprise a first tire frame and a second tire frame which are parallel to each other and located on the same horizontal plane, and a third tire frame and a fourth tire frame which are parallel to each other and located on the same horizontal plane, wherein the first tire frame and the third tire frame are on the same vertical plane, and the second tire frame and the fourth tire frame are on the same vertical plane;

[0008] Two parallel slide grooves are provided on the surface of the tire frame where the half groove is provided, and two clamping plates are connected in the slide grooves for sliding toward or away from each other;

[0009] The tire frame unit is provided with a linkage mechanism, which is used to drive the eight clamping plates to move simultaneously and make the clamping plates on all the tire frames move synchronously.

[0010] Through the above technical scheme, a tire bead is arranged on the tire frame of a device for assisting steel structure welding, so that the movement of steel components placed on the tire frame is more labor-saving; when assembling steel components on the ground, a number of tire frame units are arranged, and after the steel components are hoisted onto the tire frame units, the clamping plates on each tire frame in the tire frame unit are driven by the linkage mechanism to move toward or away from each other along the slide groove, and the clamping plates on each tire frame move synchronously to drive the steel components to move, so as to realize the precise adjustment of the position of the steel components, which not only reduces the possibility of position deviation between steel components, but also does not require tower cranes or truck cranes to work in this process, so that the lifting equipment can do other work, thereby improving the work efficiency on site; setting two-layer tire frames realizes the positioning welding of multi-layer steel components, so that the device can be used in more working conditions.

[0011] Preferably, one side of the clamping plate is rotatably connected with a connecting rod, and the tire frame side wall is provided with a receiving groove for the connecting rod to move, and the receiving groove is connected with the slide groove, and when the clamping plate slides to one end of the slide groove, the connecting rod can be further rotated into the receiving groove;

[0012] Locking pieces are detachably connected between adjacent connecting rods of the first tire frame and the second tire frame, and between adjacent connecting rods of the third tire frame and the fourth tire frame.

[0013] Through the above technical solution, the slide groove is connected with the storage groove, so that the clamping plate can be driven to move when the connecting rod moves; when the tire frame unit is used to accurately position the steel structure, the connecting rod is rotated to a state perpendicular to the length direction of the tire frame, and the connecting rods between the tire frames are connected by locking pieces, so that the four tire frames form an integral tire frame unit; when the device is not needed, the connecting rod is disconnected and rotated to retract into the storage groove on the side of the tire frame for easy transportation.

[0014] Preferably, the locking member comprises a connecting block, a side wall of the connecting block is provided with a first slot for the connecting rod to be inserted into, an inner wall of the first slot is provided with a second slot, and the connecting rod is slidably connected with a card block for being inserted into the first slot and the second slot.

[0015] Through the above technical solution, when using the connecting block to connect the connecting rods between adjacent tire frames, it is only necessary to insert the card block on the connecting rod into the first card slot and the second card slot, which is simple to operate; at the same time, the connecting block has a simple structure, is small and portable, and is easy to replace, making the connection between the connecting rods more convenient.

[0016] Preferably, the connecting rod includes a clamping joint away from one end of the clamping plate, the clamping joint is provided with a movable groove for sliding a clamping block, a spring is arranged between the inner wall of the movable groove and the end of the clamping block, a reset column is fixed on the clamping block, a long hole for moving the reset column is arranged on the side wall of the movable groove, the surface of the clamping block away from the spring is an inclined guide surface, and the guide surface is pushed to move by the edge of the opening of the first clamping groove.

[0017] Through the above technical scheme, the connection and disconnection of the connecting rod are realized by using the card joint and the connecting block in combination, the card joints on the connecting rods on the two tire frames are respectively inserted into the first card slot and the second card slot on both sides of the same connecting block, and the inclined guide surface of the card block slides along the inside of the first card slot. At this time, the spring is compressed until the card block is inserted into the second card slot, and the spring is reset to realize the connection between the card joint and the connecting block; when the connecting rod needs to be disconnected, the hand is inserted into the long hole on the connecting block to move the reset column in the direction of the compressed spring, and the connecting rod can be pulled out.

[0018] Preferably, a threaded hole is formed on the connecting block parallel to the length direction of the tire frame, and the linkage mechanism includes two parallel bidirectional screw rods, and different threaded segments of the bidirectional screw rods are respectively threadedly connected to the threaded holes of two connecting blocks on the same horizontal plane. The linkage mechanism also includes a driving source that simultaneously drives the two bidirectional screw rods to rotate.

[0019] Through the above technical solution, a through threaded hole is opened on the connecting block to realize the connection between the bidirectional screw and the connecting rod. When the bidirectional screw starts to rotate under the drive of the driving source, it can drive the two connecting blocks on a bidirectional screw to move toward or away from each other synchronously to realize the adjustment of the position of the steel component.

[0020] Preferably, two coaxially rotatably connected transmission rods are vertically connected at both ends of the driving source, and a first bevel gear is coaxially fixed to one end of the two transmission rods away from the driving source.

Through the two mutually meshing bevel gears on the transmission rod and the two-way screw rod, the two transmission rods drive the two two-way screw rods to rotate, thereby driving the connecting rod and the clamping piece connected to the connecting rod to move, so as to achieve the purpose of accurately adjusting the position of the steel component. The setting of the transmission rod realizes the effect of one driving source driving eight clamping pieces to work in linkage, simplifies the construction steps and improves the construction efficiency.

[0022] Preferably, first fixing grooves are provided at both ends of the surface of the first tire frame facing the third tire frame and at both ends of the surface of the second tire frame facing the fourth tire frame, second fixing grooves are provided at both ends of the surface of the third tire frame facing the first tire frame and at both ends of the surface of the fourth tire frame facing the second tire frame, and a support frame is inserted between the first fixing grooves and the second fixing grooves relative to each other.

[0023] Through the above technical solution, fixing grooves are opened on the upper tire frame and the lower tire frame, and then the two ends of the support frame are inserted into the fixing grooves to support the upper tire frame. The operation is convenient and construction errors are not easy to occur during the construction process.

[0024] Preferably, the support frame includes a first rod segment and a hydraulic cylinder fixedly connected below the first rod segment for adjusting the height of the support frame.

[0025] Through the above technical scheme, for the welding of steel components of different heights, the height of the support frame can be adjusted by the hydraulic cylinder to adapt to the welding of different steel components; if the steel corridor has several layers of steel components, the frame of the second layer of steel components can be lowered and lifted away by the height-adjustable support frame, and then the height of the support frame can be raised again, and the frame can be lifted to the adjusted frame, and the position of the steel structure can be adjusted and welded again, saving construction costs.

[0026] Preferably, the support frame is provided with a tossing support on both sides, one end of the tossing support is rotatably connected to the support frame, and the other end abuts against the ground.

[0027] Through the above technical solution, the castor braces are arranged on both sides of the support frame to reinforce the support frame, thereby improving the supporting effect of the support frame, reducing the possibility of the support frame tipping over, and enhancing the stability of the entire tire frame system; at the same time, the castor brace rod is rotatably connected to the support frame, and the angle of the castor brace can be adjusted according to the actual on-site environment, so that the castor brace can be supported on a better ground.

[0028] In a second aspect, the present application provides a steel structure welding method, using the auxiliary steel structure welding device as described above, and adopting the following technical solution:

[0029] A method for assisting steel structure welding comprises the following steps:

[0030] S1: After welding the vertical steel members and the horizontal steel members into T-shaped steel members in advance, several cradles are fixed in parallel to the corresponding positions on the ground, and the bottom horizontal steel members are hoisted onto the cradles by a tower crane;

[0031] S2: Insert one end of several support frames into the first fixing groove of the tire frame, install the casters on both sides of the support frames, and adjust the support frames to the corresponding height before hoisting the second tire frame; after the tire frame is erected, hoist the pre-welded T-shaped components to the second tire frame through the tower crane

[0032] S3: The driving source drives the linkage mechanism to move, and the steel components on the tire frame are adjusted to be aligned through eight clamping plates;

[0033] S4: Manually push the steel components to make the steel structure move along the length direction of the steel components so that the two adjacent steel components are pressed against each other. At this time, the welder goes to the joint to weld;

[0034] S5: After welding is completed, lower the height of the support frame, lift the tire frame above the support frame to the ground, adjust the height of the support frame again, and repeat the above steps to weld the higher-level trusses.

[0035] Through the above technical scheme, the vertical steel members and the horizontal steel members are pre-welded first, so that the upper steel members can be hoisted to the corresponding position, and then the upper steel members and the lower steel members are synchronously adjusted in position through the device. After the position adjustment is completed, the entire steel member is welded. Compared with the traditional construction method of first welding the lower horizontal steel member and then welding the vertical steel member and then welding the upper horizontal steel member, and the whole process is manually positioned and adjusted, the construction method of the present application has the advantages of faster construction, higher tower crane working efficiency and more precise positioning.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. The precise alignment of the upper and lower steel components is achieved through the linkage of the eight clamping plates on each tire frame unit. Several tire frame units adjust the position of the steel components at the same time, which reduces the construction error between the components of the entire steel corridor structure, making the construction quality more accurate and better.

[0038] 2. The various components of the device are detachably connected. When in use, the various rods and the tire frame can be connected to form a linked whole through the connecting components. When not in use, the various components can be disassembled into separate components, which is convenient for transportation and replacement and maintenance. The connection method between the various components is also simple and fast, which is convenient for workers to construct.

[0039] 3. The traditional construction method requires a crane or tower crane to lift the steel structure all the time, and then the operator manually adjusts the position of the steel structure on the frame, and then communicates with the tower crane driver through a pager to move and slowly lift the steel structure down. During the descent, you must always pay attention to adjusting the position of the steel structure to ensure that the construction error is within a few millimeters. Through this device, the steel structure can be lifted to the frame by a tower crane or crane without precise positioning, freeing up the tower crane and crane, reducing the rental cost of transportation equipment, and improving the efficiency of machinery use.

[0040] 4. Setting tire beads on the tire frame makes the movement of steel components more labor-saving. When manual fine-tuning is required, workers can also manually operate to achieve the adjustment purpose. BRIEF DESCRIPTION OF THE DRAWINGS

The first tire frame 111 and the third tire frame 113 are on the same vertical plane, and the second tire frame 112 and the fourth tire frame 114 are on the same vertical plane.

[0050] The top surface of the tire frame 11 is provided with a plurality of spherical half grooves 115 along the length direction, and tire beads 116 are movably arranged in the half grooves 115, and the tire beads 116 can roll in any direction in the half grooves 115; the tire frame 11 is provided with two parallel slide grooves 117 along the length direction on the plane where the half grooves 115 are provided, and the tire frame 11 is provided with two clamping plates 118 that slide toward or away from each other along the slide grooves 117, and the clamping plates 118 are clamped in the slide grooves 117. On the opposite surfaces of any two tire frames 11 on the same horizontal plane, there are storage grooves 119 along the length direction of the tire frame 11, and the storage grooves 119 are connected with the adjacent slide grooves 117. Each tire frame 11 is provided with two connecting rods 12 rotatably connected to the clamping plate 118 on the surface of the receiving groove 119. The connecting rod 12 can move along the receiving groove 119, and a connecting block 31 is connected between the ends of the connecting rod 12 arranged on the two tire frames 11 on the same horizontal plane, and the detachable coaxial connection of the connecting rod 12 is realized through the connecting block 31.

[0051] Reference Figure 3 and Figure 4 Both ends of the tire frame 11 are provided with fixing grooves, both ends of the surface of the first tire frame 111 facing the third tire frame 113 and both ends of the surface of the second tire frame 112 facing the fourth tire frame 114 are provided with first fixing grooves 4, both ends of the surface of the third tire frame 113 facing the first tire frame 111 and both ends of the surface of the fourth tire frame 114 facing the second tire frame 112 are provided with second fixing grooves 5, and support frames 6 are inserted into the two opposite first fixing grooves 4 and the two opposite second fixing grooves 5. A tire frame unit 1 is supported by four support frames 6 that are parallel to each other and have the same height.

[0052] Reference Figure 3 and Figure 4The eight clamping plates on the tire frame 11 realize their synchronous movement through the linkage mechanism 2. The linkage mechanism 2 includes a driving source 22. In this embodiment, the driving source 22 is preferably a dual-axis motor. The motor is arranged at the center of the square surface surrounded by the same end of the four tire frames 11. Two transmission rods 23 are vertically connected to the upper and lower parts of the motor, and a first bevel gear 24 is coaxially fixed to the end of the transmission rod 23 away from the motor. The linkage mechanism 2 also includes two bidirectional screw rods 21 whose axial directions are parallel to the axial directions of the tire frame 11. The two bidirectional screw rods 21 are respectively arranged on the horizontal plane where the first tire frame 111 and the second tire frame 112 are located and on the horizontal plane where the third tire frame 113 and the fourth tire frame 114 are located, and the two bidirectional screw rods 21 are equidistant from the tire frames 11 on the left and right sides, respectively. The two bidirectional screw rods 21 are coaxially detachably connected to the second bevel gear 25 at one end close to the transmission rod 23, and the first bevel gear 24 is meshed with the second bevel gear 25, so that when the motor drives the transmission rod 23 to rotate, the transmission rod 23 can drive the bidirectional screw rods 21 to rotate; the two bidirectional screw rods 21 are still coaxially fixed with the second bevel gear 25 at the end away from the motor, and the two bidirectional screw rods 21 are supported in the middle of the end away from the motor by a vertical rod with the first bevel gear 24 coaxially fixed at both ends.

[0053] Reference Figure 3 and Figure 5 The connecting block 31 is provided with a threaded hole 35 in a direction parallel to the axis of the tire frame 11. Different threaded sections of each bidirectional screw rod 21 are respectively threadedly connected with a bolt hole of a connecting block 31. The two sides of the connecting block 31 opposite to the tire frame 11 are provided with a first card slot 32 for the connecting rod 12 to be inserted, and the inner wall of the first card slot 32 is provided with a second card slot 33. A card joint 121 is provided at one end of the connecting rod 12 away from the clamping piece, and the card joint 121 is integrally formed with the connecting rod 12; a movable groove 123 is provided on one side wall of the card joint 121, and a card block 122 that can slide in the movable groove 123 is provided in the movable groove 123, and the end of the card block 122 is connected to the inner wall of the movable groove 123 by a spring 124, and the surface of the card block 122 away from the spring 124 is an inclined guide surface 127. In a natural state, the block 122 protrudes from the side wall of the card connector 121, and a reset column 125 is threadedly connected to the block 122. The connector is also provided with a long hole 126 that is connected to the first card slot 32. The reset column 125 is integrally formed with the block 122 and can slide along the long hole 126.

[0054] When the construction personnel connect the connecting block 31 with the connecting rod 12, the clamping joint 121 on the connecting rod 12 is respectively inserted into the first clamping groove 32 on both sides of the connecting block 31, and the inclined guide surface 127 of the clamping block 122 abuts against the opening edge of the first clamping groove 32, pushing the clamping block 122 to slide. At this time, the spring 124 is compressed until the clamping block 122 and the second clamping groove 33 are aligned, and the spring 124 is reset, and the clamping block 122 is inserted into the second clamping groove 33 to realize the connection between the clamping joint 121 and the connecting block 31; an operating hole 34 is opened on the connecting block 31, and the reset column 125 is located in the operating hole 34. When the clamping joint 121 and the connecting block 31 need to be disconnected, the user can reach into the operating hole 34 on the connecting block 31 and move the reset column 125 in the direction of the compressed spring 124 to pull out the connecting rod 12.

[0055] Reference Figure 3 The motor drives the upper and lower transmission rods 23 to rotate, and the transmission rod 23 drives the two bidirectional screw rods 21 to rotate through the first bevel gear 24. Connecting blocks 31 are sleeved on both ends of the bidirectional screw rods 21. Both sides of each connecting block 31 are clamped with the connecting rods 12 on the tire frame 11. When the bidirectional screw rods 21 rotate, they drive four pairs of connecting rods 12 on the same axis to move toward or away from each other, thereby driving the two clamping plates 118 on each tire frame 11 to move toward or away from each other, and the clamping plates 118 on the four tire frames 11 all move synchronously. The movement of the clamping plates 118 drives the steel components on the tire frame 11 to move, thereby realizing precise adjustment of the position of the steel components.

[0056] Reference Figure 3 The support frame 6 includes a first rod section 61 and a hydraulic cylinder 62 fixedly connected to the bottom of the first rod section 61. The height adjustment of the support frame 6 is achieved by the hydraulic cylinder 62. In this embodiment, the lifting pressure of the hydraulic cylinder 62 is preferably considered according to the maximum weight of the steel structure of this project. A tossing brace 7 is provided on both sides of the support frame 6, and a lug plate with holes is welded on both sides of the support frame 6. One end of the tossing brace 7 is connected to the lug plate on the support frame 6 by bolts to achieve a rotatable connection between the tossing brace 7 and the support frame 6. The other end of the tossing brace 7 is against the ground. When the bolts are tightened, the tossing brace 7 can support the tire frame unit 1 more stably.

[0057] The implementation principle of the device for assisting steel structure welding in the embodiment of the present application is as follows: four mutually parallel and aligned tire frames 11 form a tire frame unit 1, and a plurality of tire frame units 1 are used to achieve precise positioning of the steel components before welding. Before welding the steel corridor trusses, the construction personnel first fix a plurality of first tire frames 111 and second tire frames 112 on the ground at intervals, hoist the steel components to the top of the tire frames 11 perpendicular to the length direction of the tire frames 11, and then hoist and insert a plurality of support columns into the first fixed grooves 4, support the casters 7 on both sides of the support columns, and after the support is completed, hoist and splice a plurality of third tire frames 113 and fourth tire frames 114 to the upper ports of the support columns, hoist the steel components to the third tire frames 113 and the fourth tire frames 114, and place them perpendicular to the axis direction of the third tire frames 113, and then install the linkage mechanism 2.

[0058] First, rotate the connecting rod 12 in each tire frame 11 into the receiving groove 119 to a position perpendicular to the length direction of the tire frame 11, and insert the end of the connecting rod 12 away from the clamping plate 118 into the connecting block 31, so that the two connecting rods 12 on the coaxial line between the two tire frames 11 become one rod through the connecting block 31. After all the clamping is completed, a plurality of bidirectional screw rods 21 are inserted into the threaded holes 35 of the two connecting blocks 31, and one end of the bidirectional screw rod 21 is provided with a second bevel gear 25 which meshes with the first bevel gear 24 on the transmission rod 23. The other end of the transmission rod 23 is connected to the motor, and a bracket is provided under the motor to support the motor.

[0059] After the erection is completed, start the motor, and the motor drives the upper and lower transmission rods 23 to rotate synchronously, and drives the upper and lower bidirectional screw rods 21 to rotate through the first bevel gear 24 and the second bevel gear 25. During the rotation of the bidirectional screw rod 21, the connecting block 31 mounted on the screw rod is driven to move toward or away from each other, thereby driving the connecting rod 12 and the clamping plate 118 rotatably connected to the connecting rod 12 to move toward or away from each other. The eight clamping plates 118 on a tire frame unit 1 all move toward each other synchronously, thereby driving the steel components on the tire frame 11 to adjust their positions. Because tire beads 116 are provided on the surface of the tire frame 11, the friction between the steel components and the tire frame 11 is reduced, allowing the steel components to move under the movement of the clamping plates. After the position of the steel components is adjusted, the workers push the steel components to move in a direction perpendicular to the length of the tire frame 11, so that the steel components on adjacent tire frame units 1 can be pressed tightly. After the positioning of the steel components is completed, the construction personnel connect the steel components to achieve precise positioning and connection of the steel structure.

[0060] The present application also discloses a construction method for the above-mentioned device, which comprises the following steps:

[0061] S1: After welding the vertical steel members and the horizontal steel members into T-shaped steel members in advance, several tire frames 11 are fixed parallel to corresponding positions on the ground, and the bottom horizontal steel members are hoisted onto the tire frames 11 by a tower crane;

[0062] S2: Insert one end of a plurality of support frames 6 into the first fixing groove 4 of the tire frame 11, install the casters 7 on both sides of the support frames 6, and adjust the support frames 6 to the corresponding height before hoisting the second tire frame 112; after the tire frame 11 is erected, hoist the pre-welded T-shaped components onto the second tire frame 112 by a tower crane.

[0063] S3: The linkage mechanism 2 is driven by a motor to move, and the steel components on the tire frame 11 are adjusted to be aligned through eight clamping plates 118;

[0064] S4: Manually push the steel components to make the steel structure move along the length direction of the steel components so that the two adjacent steel components are pressed against each other. At this time, the welder goes to the joint to weld;

[0065] S5: After the welding is completed, the height of the support frame 6 is lowered, and the tire frame 11 above the support frame 6 is hoisted to the ground. After the height of the support frame 6 is adjusted again, the above steps are repeated to weld the higher-level trusses.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
