Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding and assembly, and particularly to a steel structure splicing adjustment device. Background Art

[0002] With the rapid development of modern construction technology, steel structures have been widely used in large bridge projects, high-rise buildings and large-span space structures due to their advantages such as high strength, light self-weight and short construction period. Especially in the field of bridge construction, steel structure components often need to be spliced on site to form an integral structure, and the splicing accuracy directly affects the mechanical properties and safety stability of the bridge.

[0003] For example, the Chinese patent "CN119216911B" discloses "a steel structure butt welding adjustment device". Through the cooperation of a workbench, a welding robotic arm, a clamping mechanism, a fixed base, a movable fixing plate, rollers, a three-jaw chuck, a first spring, an auxiliary fixing plate, a second spring, a telescopic block, a first sleeve plate, a movable shaft, a first reciprocating lead screw, an electric telescopic rod and a clamping plate, the movable fixing plate and the rollers support two steel pipes, ensuring that the two steel pipes will not shift during butt welding, improving the welding quality of the device. At the same time, when the three-jaw chuck clamps the steel pipe from the inner pipe, the auxiliary fixing plate will extend and contact the inner wall of the steel pipe, thereby increasing the clamping area and further improving the clamping stability of the steel pipe to prevent the steel pipe from shifting during welding. However, steel structure designs usually have various angles. The above device can only move the steel structure along the axial direction during use and cannot meet the splicing operations of various steel structures with angles. Other adjustment devices need to be customized for convenient use, which not only increases the cost but also reduces the efficiency of steel structure splicing. Summary of the Invention

[0035] The following further describes the technical solutions in the present invention with reference to FIGS. Figure 1 -7 and the embodiments.

[0036] An embodiment of the present invention provides a steel structure splicing adjustment device for installing a steel beam 1, including:

[0037] A bearing frame 2 having two mirror - set mounting surfaces, with the steel beam 1 located between the two mounting surfaces;

[0038] Adjusting disks 4, with two adjusting disks 4 respectively rotatably arranged on the two mounting surfaces. The adjusting disk 4 is provided with an adjusting member and two fixing plates 7, and the steel beam 1 is located between the two fixing plates 7. The adjusting member is connected to the two fixing plates 7 and is used to adjust the distance between the two fixing plates 7 to fix the steel beam 1; and

[0039] A driving assembly, arranged on the bearing frame 2 and connected to the two adjusting disks 4, for adjusting the angle of the adjusting disks 4 to adjust the splicing angle of the steel beam 1.

[0040] In the embodiment of the present invention, as Figure 1 shown, the bearing frame 2 has a U - shaped structure with the opening of the U - shaped structure facing upward. The steel beam 1 is an H - shaped steel. When welding and assembling the steel beam 1, the steel beam 1 can be installed on the fixing plate 7 by means of hoisting. Therefore, under the action of the opening of the U - shaped structure facing upward, the lifting rope can be installed at the middle position of the steel beam 1 to ensure the stability of the steel beam 1 during hoisting. At the same time, when installing the steel beam 1, first, adjust the height of the steel beam 1 through a hoisting device so that the height of the upper flange of the steel beam 1 is higher than the fixing plate 7 at the top of the adjusting disk 4, and the lower flange of the steel beam 1 is lower than the fixing plate 7 at the bottom of the adjusting disk 4. Then, control the hoisting device to translate, gradually let the steel beam 1 penetrate between the two fixing plates 7. After adjusting the position, lower the steel beam 1 through the hoisting device so that the upper flange of the steel beam 1 is placed on the fixing plate 7 at the top of the adjusting disk 4 and is carried by this fixing plate 7. In the installation method of this fixing plate 7, it can be fixedly installed, mainly for the initial load - bearing of the fixing plate 7.

[0041] Secondly, after the steel beam 1 is installed, as Figure 2 shown, each fixing plate 7 of the two adjusting disks 4 is in a horizontal state, and the steel beam 1 is installed on the fixing plate 7 at the top of the adjusting disk 4 under the action of gravity. At this time, the fixing plate 7 at the bottom of the adjusting disk 4 does not contact the lower flange of the steel beam 1. Considering that the web heights of different steel beams 1 are different, before use, control the position of this fixing plate 7 close to the top fixing plate 7. During the horizontal welding operation, the adjusting member may not be operated to adjust the positions of the two fixing plates 7. However, in order to ensure the stability of the welding of the two steel beams 1, it is preferred to operate the adjusting member to adjust the positions of the two fixing plates 7. It should be noted that, as Figure 4As shown, during normal welding operations, two or more adjustment devices are required to be used in combination. Since the fixing plate 7 located at the top of the adjustment disc 4 is installed on the adjustment disc 4 by fixing, the adjusting member is mainly used to adjust the position of the bottom fixing plate 7, so that the fixing plate 7 moves up and down on the adjustment disc 4 to adjust the distance between the two fixing plates 7. After the steel beam 1 is placed on the top fixing plate 7, the adjusting member is used to control the downward movement of the bottom fixing plate 7 until it abuts against the lower flange of the steel beam 1, realizing the clamping of the steel beam 1 and ensuring stability. Among them, the adjusting member can be a telescopic adjustment structure, such as hydraulic, pneumatic, oil pressure or electric means, or a threaded adjustment mechanism, such as a screw rod or a lead screw.

[0042] Furthermore, for different construction contents, in the splicing of the steel beam 1, there are often cases where there is an included angle between the steel beams 1, such as the shape structure of the steel structure and the connection of adjacent steel structures. Therefore, in the initial stage of splicing the steel beam 1, the steel beam 1 can be adjusted in angle first and then welded, as Figure 5 shown. The angles of the adjustment discs 4 in the two adjustment devices are respectively adjusted. Under the cooperation of the driving component and the adjustment disc 4, the adjustment disc 4 rotates on the installation surface of the bearing frame 2. The driving component can synchronously drive the adjustment discs 4 on the two installation surfaces, so that the adjustment disc 4 rotates on its own axis on the installation surface of the bearing frame 2, thereby driving the two fixing plates 7 on the adjustment disc 4 to rotate around the adjustment disc 4 as the axis. The splicing angle of the steel beam 1 can be adjusted according to actual needs, without the need to customize other adjustment devices additionally, simplifying the operation process and improving the efficiency of steel structure splicing. Among them, the driving component can be a wheel transmission mechanism, such as a sprocket and chain mechanism, or a belt and pulley transmission structure, or it can also be a direct drive method of a motor or a motor respectively.

[0043] Finally, not only the case of direct butt joint of two steel beams 1, as Figure 6 shown. When the main beam is determined and several steel beams 1 need to be welded to the same main beam, each adjustment device can be circumferentially arranged around the main beam, and the steel beams 1 in each adjustment device are respectively adjusted to meet the welding of each steel beam 1 at the same time, greatly increasing the on-site splicing efficiency. In Figure 5 and Figure 6 , the welding situations where the ends of the steel beam 1 are tilted upward are shown. Specifically, the steel beam 1 can also be tilted downward according to actual use to meet different splicing requirements.

[0044] Specifically, in order to facilitate the adjustment of the distance between the two fixing plates 7, as Figure 2 and Figure 3 shown, the adjusting member includes:

[0045] The adjusting screw rod 404 and the adjusting disk 4 are provided with two fixing blocks 403 correspondingly, and the adjusting screw rod 404 is rotatably arranged between the two fixing blocks 403;

[0046] The first adjusting block 701 and the second adjusting block 703, the adjusting disk 4 is provided with a mounting groove 406, the first adjusting block 701 and the second adjusting block 703 are both arranged in the mounting groove 406 and are located between the two fixed blocks 403, and the first adjusting block 701 and the second adjusting block 703 are respectively connected to the two fixed plates 7, the first adjusting block 701 is provided with a threaded sleeve 702, and the threaded sleeve 702 is threadedly connected to the adjusting screw 404.

[0047] The adjustment method using the adjusting screw rod 404 can accurately adjust the size of the two fixed plates 7. Specifically, when the two fixed plates 7 are adjusted by the adjusting member, the second adjusting block 703 is fixedly arranged in the mounting groove 406, so that the fixed plate 7 connected to the second adjusting block 703 is in a fixed state, and mainly plays the role of supporting the steel beam 1. When the steel beam 1 is placed on this fixed plate 7, its stability can be guaranteed. Then, the threaded sleeve 702 is fixedly connected to the first adjustment block 701, and the through hole of the second adjustment block 703 is directly larger than the diameter of the adjustment screw 404. When the adjustment screw 404 is rotated, the threaded sleeve 702 moves downward along the axial direction of the adjustment screw 404 under the action of the first adjustment block 701, so that the first adjustment block 701 drives the corresponding fixed plate 7 to abut against the lower flange of the steel beam 1, and the rotation of the adjustment screw 404 can be stopped. Self-locking is achieved under the action of the thread, and the steel beam 1 is frictionally fixed. Preferably, the plane of the fixed plate 7 close to the flange of the steel beam 1 can be roughened to increase the friction between the fixed plate 7 and the flange of the steel beam 1, and indirectly improve the stability of its friction fixation. Moreover, the spacing between the two fixed plates 7 is adjustable, which can be applied to steel beams 1 with different flange spacings.

[0048] In the above-mentioned improved method of installing the second adjustment block 703 in a fixed manner, the fixing method may be a method of receiving the threaded tube 405, such as Figure 2 As shown, the adjusting screw 404 is threadedly connected with a threaded tube 405, the second adjusting block 703 is sleeved on the adjusting screw 404, and the threaded tube 405 abuts against the bottom end of the second adjusting block 703. By threading the threaded tube 405 on the adjusting screw 404, when the threaded tube 405 is rotated, the threaded tube 405 can be moved along the axial direction of the adjusting screw 404. When the rotation stops, the threaded tube 405 can be stopped under the action of the thread. The second adjusting block 703 is sleeved on the adjusting screw 404 so that the threaded tube 405 carries it. When the threaded tube 405 is rotated to make it move up and down on the adjusting screw 404, the second adjusting block 703 can be driven to move up and down on the adjusting disk 4. When the two steel beams 1 are butt-joined at different heights or asFigure 7 As shown, when different steel beams 1 need to be welded at different positions on the main beam, the threaded pipe 405 can be rotated to drive the second adjusting block 703 to move up and down, thereby changing the position of the corresponding fixing plate 7, and then changing the initial position of the steel beam 1 hoisted to the top fixing plate 7, realizing the splicing of steel structures at different positions.

[0049] Based on the fact that the web thickness of each steel beam 1 is different, as Figure 2 shown, at least two connecting rods 704 are passed through the second adjusting block 703, and each connecting rod 704 penetrates through the end face of the second adjusting block 703 and is connected to the corresponding fixing plate 7; when the steel beam 1 is hoisted onto the top fixing plate 7, if there is a certain distance between both sides of the web and the two fixing plates 7 on both sides, the lateral position of the steel beam 1 may occur during the welding of the steel beam 1, resulting in a decrease in welding quality. In severe cases, it may be necessary to cut and weld again. Therefore, after the steel beam 1 is installed on the top fixing plate 7, by adjusting the connecting rod 704 of one of the second adjusting blocks 703, the connecting rod 704 slides on the second adjusting block 703, so that the corresponding fixing plate 7 moves along the axis direction of the connecting rod 704, so that the web of the steel beam 1 abuts against another fixing plate 7. After each adjusting device is adjusted, it can ensure that the steel beams 1 correspond to each other, ensuring the welding accuracy. It should be noted that only one of the second adjusting blocks 703 is provided with a connecting rod 704, and the fixing plate 7 of the other second adjusting block 703 serves as a positioning function.

[0050] Specifically, a limiting groove 402 is opened on the side of the installation groove 406. The first adjusting block 701 and the second adjusting block 703 are both slidably clamped in the limiting groove 402. When the fixing plate 7 bears the bearing capacity, the fixing plate 7 will receive a downward turning force. Under the action of the limiting groove 402, the first adjusting block 701 and the second adjusting block 703 will be limited by the limiting groove 402, so that the first adjusting block 701 and the second adjusting block 703 can only move along the length direction of the limiting groove 402, thereby reducing the pressure on the adjusting screw rod 404.

[0051] Based on the above solution, in order to realize the stable driving of the adjusting disk 4, as Figure 2 shown, the driving assembly includes:

[0052] A rack 401, which is circumferentially arranged along the outer peripheral side of the adjusting disk 4;

[0053] A gear 601, which is rotatably arranged on the bearing frame 2 and meshes with the rack 401; and

[0054] A first driving member, which is arranged on the bearing frame 2 and is used to drive the gear 601 to rotate.

[0055] Specifically, the rack 401 is arranged along the circumferential direction of the adjusting disc 4. Taking the midline of the adjusting disc 4 as the reference, the middle position corresponds to the middle part of the rack 401, and the rack 401 is distributed on both sides of the midline. When the adjusting disc 4 is rotationally adjusted, the first driving member drives the gear 601 to rotate. Thus, under the cooperation of the gear 601 and the rack 401, the rack 401 travels on the rotating gear 601, so that the adjusting disc 4 rotates on the bearing frame 2. Furthermore, the fixing plate 7 is driven by the adjusting disc 4 to rotate around the adjusting disc 4 as the axis. In order to control the synchronous angular adjustment of the two adjusting discs 4, the first driving member can be a separate motor or a motor, which are respectively connected to the adjusting disc 4 and are synchronously controlled by a control element.

[0056] Specifically, in order to reduce the number of devices used and energy consumption, the first driving member is a bidirectional motor 6, and the output shafts of the bidirectional motor 6 are respectively connected to the two gears 601; the two output shafts of the bidirectional motor 6 are respectively connected to the two gears 601. When the bidirectional motor 6 is turned on, the two output shafts of the bidirectional motor 6 synchronously drive the two gears 601 to rotate, so as to realize the synchronous drive of the two adjusting discs 4. One device can be used to adjust the two adjusting discs 4, which not only saves energy but also reduces the procurement of equipment. At the same time, the bidirectional motor 6 also has a self-locking function. When the bidirectional motor 6 is powered off or turned off, the position of the adjusting disc 4 can be locked, which improves the safety while ensuring the stability.

[0057] Based on the above solution, in order to facilitate the movement and docking of the steel beam 1, a base 3 is further included. The bearing frame 2 is slidably arranged on the base 3, and the base 3 is also provided with a second driving member for pushing the bearing frame 2 to move; under the action of the second driving member, the bearing frame 2 can be pushed to slide in the base 3, so that the steel beam 1 to be welded moves slowly for docking, which is convenient for welding. Among them, the second driving member can be a telescopic structure, such as pneumatic, hydraulic, oil pressure, and electric telescopic methods, or a screw drive method, such as screw drive.

[0058] Specifically, the second driving member is a jack 5. The jack 5 is arranged at the end of the base 3, and its telescopic end is connected to the end of the bearing frame 2; the jack 5 can provide a strong lateral thrust. When moving the bearing frame 2, by starting the jack 5, the telescopic end of the jack 5 extends, so as to drive the bearing frame 2 to move in the base 3. When the jack 5 stops, the bearing frame 2 can be stopped in time, and the moving distance and speed of the bearing frame 2 can be accurately controlled, which helps to ensure the precise positioning of the steel beam 1 during the splicing process, thereby improving the quality of the final structure. Moreover, it replaces direct manual operation, which can reduce potential safety hazards caused by manual adjustment and improve the safety of the operation site. After use, it is necessary to release the fixation of the steel beam 1 by the fixing plate 7, and then the telescopic end of the jack 5 is contracted to return to the original position to ensure subsequent reuse.

[0059] Meanwhile, a slider 202 is provided on the side of the carrier 2, and a slide rail 201 is provided on the inner side of the base 3. The slider 202 is slidably connected to the slide rail 201. The sliding connection between the slider 202 and the slide rail 201 ensures that the carrier 2 can move smoothly and stably on the base 3, which can reduce the friction and resistance during the movement, making it easier and more efficient for the jack 5 to push the carrier 2. At the same time, the cooperation of the slider 202 and the slide rail 201 increases the rigidity and stability of the whole system, prevents the carrier 2 from unnecessary deviation or shaking during the movement, and ensures the quality of the steel structure splicing.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
