Description

Technical Field

[0001] The invention relates to the technical field of steel structure construction, and in particular to a three-dimensional adjustable steel structure positioning and assembling bracket and an assembling method thereof. Background Art

[0002] The triangular tube truss is a triangular lattice structure composed of steel tube members. It is widely used in construction and other fields. It is mainly composed of chords, webs, node plates, supports and other parts. The triangular structure is stable and can make the entire truss structure strong and stable. It can give full play to the mechanical properties of the material and effectively bear various loads, including self-weight, wind loads, snow loads, etc. In large-span buildings, compared with other structural forms, it can obtain a larger span and bearing capacity with less material. The triangular tube truss splicing tool plays a vital role in the splicing process of the truss. The splicing tool is usually precisely designed and manufactured according to the design size and shape of the triangular tube truss. It is equipped with a positioning device and a limit structure to accurately determine the position and angle of each member. During splicing, the members can be accurately placed in the predetermined position, thereby ensuring the geometric size accuracy of the truss, ensuring that the shape and size of the truss meet the design requirements, and avoiding the degradation of structural performance due to splicing errors. Traditional fixed splicing tooling can only be used to produce triangular tube trusses of the same specification. For this reason, tooling with adjustment functions has appeared on the market, which can make adjustments according to the chord width and chord height. However, there are some defects in its processing: the two ends of the chord are supported on the end frames, and there is a lack of support in the middle. Therefore, another tooling is required to first splice multiple sections of chords and then transfer them to the splicing tooling. When the span of the triangular tube truss is long, its installation accuracy will be affected under the influence of its own weight; the truss height adjustment mechanism is a screw mechanism. Although its adjustment accuracy is high, its load capacity is poor and it cannot be used for the installation of triangular tube trusses with large spans or large deadweights; for triangular tube trusses with variable cross-sections, because the chord width and chord height are different at different parts, the equipment cannot be used for the installation of triangular tube trusses with changing chord width and chord height. In view of this, this case arises. Summary of the invention

[0021] The present invention is further described below through specific implementation modes.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figure 1As shown, the three-dimensional adjustable steel structure positioning and assembling bracket of the present invention includes a base 60, a side support frame 10 and a lower support frame 20. The base 60 is provided with a plurality of side support frames 10 located in the left row, a plurality of lower support frames 20 located in the middle row and a plurality of side support frames 10 located in the right row. Figure 3 , 5 As shown in , 6, the side support tire frame 10 includes an adjustment base 1, a column 2, a lateral adjustment mechanism 3, a support 4, a side clamping plate 5 and a longitudinal adjustment mechanism 6. The adjustment base 1 is fixed on the base 60, the column 2 moves laterally on the adjustment base 1 through the lateral adjustment mechanism 3, the support 4 moves longitudinally on the column 2 through the longitudinal adjustment mechanism 6, the side clamping plate 5 is arranged on the support 4, and a lower clamping plate 201 is arranged on the top of the lower support tire frame 20, and the side clamping plate 5 is located higher than the lower clamping plate 201. Figure 2As shown, the three-dimensional adjustable steel structure positioning and assembling bracket of the present invention is used as a pre-installed tooling for the triangular tube truss on the ground. When in use, the two side chord rods 30 are respectively placed on the side clamping plates 5 of the side support tire frames 10 on the left and right sides, and the lower chord rod 40 is placed on the lower clamping plate 201 of the lower support tire frame 20. The chord rods are connected by the web rod 50, so as to complete the assembly of the triangular tube truss on the ground. The base 60 is provided with a plurality of span side support tire frames 10, and the length and number of the spans need to be adjusted according to the design size and design requirements. Each span node is provided with two left and right side support tire frames 10 that can be adjusted independently, and one or more lower support tire frames 20 are provided between the spans. As shown in the figure, it is a layout of one span, and two lower support tire frames 20 are arranged between the spans. Before assembling the triangular tube truss, the position of the side clamping plate 5 needs to be adjusted according to the design requirements: the column 2 is laterally moved on the adjustment base 1 through the lateral adjustment mechanism 3, so as to adjust the lateral distance between the side clamping plate 5 and the lower clamping plate 201, and then adjust the design width of the triangular tube truss; the support 4 is longitudinally moved on the column 2 through the longitudinal adjustment mechanism 6, so as to adjust the longitudinal distance between the side clamping plate 5 and the lower clamping plate 201, and then adjust the design height of the triangular tube truss. Since the lateral and longitudinal positions of the side clamping plates 5 on the left and right sides can be adjusted separately, the layout of the three chords of the triangular tube truss can be equilateral, isosceles or other triangular layouts; in addition, since the side clamping plates 5 of the left and right side support frames 10 can be adjusted independently at each node, the chord width and chord height at different spans can be adjusted independently, so as to produce triangular tube trusses with variable cross-sections to meet the production needs of special-shaped triangular tube trusses. With the assistance of the three-dimensional adjustable steel structure positioning and assembling bracket of the present invention, the triangular tube truss can be pre-installed as a whole on the ground according to actual needs, and then hoisted to high altitude for assembly, which reduces the amount of high-altitude work, improves construction safety and construction efficiency, shortens the construction period, and improves comprehensive benefits. The adjustment mechanism is used to change the node height and width to ensure that the size and shape of the triangular tube truss meet the design requirements and can be reused, without the need to customize a fixed tool for each specification of the triangular tube truss, thereby reducing production costs.

[0024] The transverse adjustment mechanism 3 includes a transverse sliding vehicle 31, an upper guide rail 32, a lower guide rail 33, a transverse screw rod 34 and a transverse driving motor 35. The column 2 is fixed on the transverse sliding vehicle 31. The transverse sliding vehicle 31 is provided with a pulley. The upper guide rail 32 and the lower guide rail 33 are fixed on the adjustment base 1. A channel for the pulley to move laterally is formed between the upper guide rail 32 and the lower guide rail 33. The transverse screw rod 34 can be rotatably arranged on the adjustment base 1 and arranged parallel to the upper guide rail 32 and the lower guide rail 33. The transverse driving motor 35 drives the transverse screw rod 34 to rotate. The transverse sliding vehicle 31 is provided with a transverse nut threadedly connected to the transverse screw rod 34, which converts the rotational motion of the transverse screw rod 34 into the transverse motion of the transverse nut and the transverse sliding vehicle 31. The main body of the transverse adjustment mechanism 3 is a screw nut mechanism, which has a medium load-bearing capacity but high adjustment accuracy, so it is suitable for transverse displacement adjustment. The upper guide rail 32, the lower guide rail 33 and the transverse screw rod 34 are arranged horizontally, and the working principle of the transverse adjustment mechanism 3 is: the transverse drive motor 35 drives the transverse screw rod 34 to rotate, and converts the rotational movement of the transverse screw rod 34 into the transverse movement of the transverse sliding vehicle 31, thereby adjusting the transverse distance between the side clamping plate 5 and the lower clamping plate 201, and then adjusting the width of the triangular tube truss. Since the side clamping plates 5 on the left and right sides can be independently adjusted laterally, the transverse distances from the lower clamping plate 201 can be the same or different. The transverse drive motor 35 uses a servo motor, and the output end of the transverse drive motor 35 is provided with a worm gear reducer, which can convert the high-speed and low-torque output of the motor into a low-speed and high-torque output. It also has a self-locking function, which can prevent the position from loosening after fine-tuning.

[0025] like Figure 3 and 6The longitudinal adjustment mechanism 6 includes a sprocket 61, a chain 62, a longitudinal slide rail 63, a longitudinal sliding vehicle 64 and a longitudinal driving motor 65. The longitudinal slide rail 63 is fixedly arranged inside the column 2, and the longitudinal sliding vehicle 64 is slidably arranged on the longitudinal slide rail 63. The support 4 is fixedly arranged on the longitudinal sliding vehicle 64. A sprocket 61 is respectively arranged at the upper and lower ends of the longitudinal slide rail 63. The chain 62 is meshed with the two sprockets 61. The longitudinal sliding vehicle 64 is fixedly connected to the chain 62. The longitudinal driving motor 65 drives the upper sprocket 61 to rotate. The longitudinal slide rail 63 is arranged along the longitudinal direction, and the longitudinal drive motor 65 is a servo motor. The output end of the longitudinal drive motor 65 is provided with a worm gear reducer, which can convert the high-speed and low-torque output of the motor into a low-speed and high-torque output. It also has a self-locking function, which can prevent the position from loosening after movement. The longitudinal drive motor 65 drives the sprocket 61 to rotate, and drives the longitudinal sliding vehicle 64 and the side clamping plate 5 to move along the longitudinal direction through the sprocket 61 and the chain 62, so as to adjust the height of the triangular tube truss. Since the side clamping plates 5 on the left and right sides can be independently adjusted longitudinally, their longitudinal distances from the lower clamping plate 201 can be the same or different. In the longitudinal adjustment mechanism 6, the longitudinal sliding vehicle 64 is driven up and down by the sprocket chain. The bearing capacity of the sprocket chain mechanism is very high, but the adjustment accuracy is relatively low. It is suitable for high-impact and high-load working conditions, so it is suitable for bearing the weight of the triangular tube truss.

[0026] The longitudinal sliding vehicle 64 is provided with an inner guide wheel 66 and an outer guide wheel 67, wherein the inner guide wheel 66 is arranged inside the longitudinal slide rail 63, and the outer guide wheel 67 is arranged outside the longitudinal slide rail 63, and the height of the inner guide wheel 66 is higher than that of the outer guide wheel 67. The inner guide wheel 66 rolls along the longitudinal slide rail 63, and the outer guide wheel 67 rolls against the outer wall of the longitudinal slide rail 63, and supports the longitudinal sliding vehicle 64 and the support 4, so that the support 4 remains in a horizontal state.

[0027] The side support tire frame 10 also includes a fine-tuning mechanism 7 arranged on the support 4, and the fine-tuning mechanism 7 includes a fine-tuning base 71, an upper wedge block 72, a lower wedge block 73, a guide column 74, a guide seat 75, a fine-tuning screw rod 76 and a fine-tuning drive motor 77. The side clamping plate 5 is detachably arranged on the fine-tuning base 71, the upper wedge block 72 is fixedly arranged below the fine-tuning base 71, the lower inclined surface of the upper wedge block 72 abuts against the upper inclined surface of the lower wedge block 73, the lower wedge block 73 can be laterally slidably arranged on the support 4, the guide seat 75 is fixedly arranged on the support 4, the top of the guide column 74 is fixedly connected to the fine-tuning base 71, and the lower part is slidably connected to the guide seat 75, the fine-tuning drive motor 77 drives the fine-tuning screw rod 76 to rotate, and the lower wedge block 73 is provided with a threaded hole threadedly connected to the fine-tuning screw rod 76. The fine-tuning drive motor 77 drives the fine-tuning screw 76 to rotate, converting the rotational motion into the lateral movement of the lower wedge block 73. Since the inclined surfaces of the upper wedge block 72 and the lower wedge block 73 fit each other, and the upper wedge block 72 can only move up and down under the limit of the guide column 74 and the guide seat 75, the lateral movement of the lower wedge block 73 is converted into the up and down movement of the upper wedge block 72, that is, the up and down movement of the side clamping plate 5. The screw adjustment mechanism composed of the fine-tuning screw 76 and the lower wedge block 73, and the wedge adjustment mechanism composed of the upper wedge block 72 and the lower wedge block 73 jointly realize the precise fine-tuning of the longitudinal displacement. The fine-tuning drive motor 77 uses a servo motor, and a worm gear reducer is set at the output end of the fine-tuning drive motor 77, which can convert the high-speed and low-torque output of the motor into a low-speed and high-torque output. It also has a self-locking function to prevent the position after fine-tuning from loosening. The fine adjustment mechanism 7 combines the characteristics of the screw adjustment mechanism and the wedge adjustment mechanism, has a small adjustment range, and has good bearing capacity and adjustment accuracy, so it is suitable for longitudinal fine adjustment. It cooperates with the longitudinal adjustment mechanism 6 with the sprocket chain as the main body, firstly performs the preliminary adjustment of the longitudinal displacement of the side support tire frame 10 through the longitudinal adjustment mechanism 6, and then the fine adjustment mechanism 7 performs the fine adjustment of the longitudinal displacement of the side support tire frame 10, so as to achieve higher adjustment accuracy and meet the dimensional accuracy requirements of production. Therefore, the lateral and longitudinal adjustment of the present invention combines multiple mechanisms such as the screw nut mechanism, the sprocket chain mechanism, and the wedge mechanism, which can meet the requirements of bearing capacity and adjustment accuracy at the same time.

[0028] The lower wedge block 73 and the support 4, and the upper wedge block 72 and the lower wedge block 73 are all slidably connected by dovetail grooves and dovetail blocks. The support 4 is provided with two dovetail grooves, the bottom of the lower wedge block 73 is provided with two dovetail blocks that slide with the dovetail grooves on the support 4, the inclined surface of the lower wedge block 73 is provided with two dovetail grooves, and the inclined surface of the upper wedge block 72 is provided with two dovetail blocks that slide with the dovetail grooves of the lower wedge block 73. Through the sliding cooperation of the dovetail grooves and the dovetail blocks, the lower wedge block 73 is restricted to move only in the lateral direction, and the upper wedge block 72 and the lower wedge block 73 can only slide relative to each other along the inclined surface, so that the rotational movement of the fine-tuning screw 76 is converted into the lateral movement of the lower wedge block 73, and finally converted into the longitudinal movement of the upper wedge block 72.

[0029] The top surfaces of the side clamping plate 5 and the lower clamping plate 201 are both arc surfaces matched with the chord rod. The side clamping plate 5 can be detachably arranged on the support 4, and the lower clamping plate 201 can be detachably arranged on the lower support tire frame 20.

[0030] A longitudinal laser displacement sensor 8 is provided on the support 4, and a transverse laser displacement sensor 9 is provided on the column 2. The longitudinal laser displacement sensor 8 is used to measure the longitudinal distance between the longitudinal laser displacement sensor 8 and the adjustment base 1, which is converted into the longitudinal distance between the side clamping plate 5 and the lower clamping plate 201 through calculation. The transverse laser displacement sensor 9 is used to measure the transverse distance between the longitudinal laser displacement sensor 8 and the end of the adjustment base 1, which is converted into the transverse distance between the side clamping plate 5 and the lower clamping plate 201 through calculation. The position parameters of the side clamping plate 5 are pre-input into the control system, and the initial position of the side clamping plate 5 is determined by the longitudinal laser displacement sensor 8 and the transverse laser displacement sensor 9, and the longitudinal and transverse displacements of the side clamping plate 5 are calculated and converted into the rotation angle required by the servo motor. The longitudinal position adjustment includes initial adjustment and fine adjustment. The longitudinal drive motor 65 is used to adjust the position of the side clamping plate 5 to the target height, and the allowable error range is less than 2 cm. Then, the fine adjustment drive motor 77 is used to further accurately adjust the position of the side clamping plate 5.

[0031] The assembly method of the three-dimensional adjustable steel structure positioning assembly bracket includes the following steps: Step a, the column 2 is laterally moved on the adjustment base 1 through the lateral adjustment mechanism 3, thereby adjusting the lateral distance between the side clamping plate 5 and the lower clamping plate 201, and the support 4 is longitudinally moved on the column 2 through the longitudinal adjustment mechanism 6, thereby adjusting the longitudinal distance between the side clamping plate 5 and the lower clamping plate 201; Step b, hang each section of the chord rod to the corresponding side clamping plate 5 and the lower clamping plate 201, the side chord rod 30 is placed on the side clamping plate 5 of the side support tire frame 10 on the left and right sides respectively, and the lower chord rod 40 is placed on the lower clamping plate 201 of the lower support tire frame 20; Step c, aligning and welding the butt joints of each chord section; Step d, assembling and welding the web members 50 in sequence; Step e: hang the assembled triangular tube truss from the three-dimensional adjustable steel structure positioning assembly bracket.

[0032] The installation method of the three-dimensional adjustable steel structure positioning assembly bracket is as follows: first lay the base 60, and the preparation method of the base 60 is as follows: it needs to be compacted by a roller first, compacted after laying the gravel, poured concrete, and laid the steel plate after hardening, and the adjustable base 1 is fixed on the steel plate, and then other components are installed.

[0033] In step a, the longitudinal adjustment mechanism 6 is adjusted by: the longitudinal drive motor 65 drives the sprocket 61 to rotate, and the longitudinal sliding vehicle 64 and the side clamping plate 5 are driven to move longitudinally through the sprocket chain transmission to achieve preliminary adjustment of the longitudinal position; After the longitudinal adjustment mechanism 6 is adjusted, the longitudinal fine adjustment is performed through the fine adjustment mechanism 7. The fine adjustment drive motor 77 drives the fine adjustment screw 76 to rotate, and the rotational motion is converted into the lateral movement of the lower wedge block 73. The upper wedge block 72 can only move up and down under the limit of the guide column 74 and the guide seat 75. The lateral movement of the lower wedge block 73 is converted into the up and down movement of the upper wedge block 72, thereby realizing the fine adjustment of the longitudinal displacement; The adjustment method of the lateral adjustment mechanism 3 is as follows: the lateral drive motor 35 drives the lateral screw rod 34 to rotate, and converts the rotational movement of the lateral screw rod 34 into the lateral movement of the lateral sliding vehicle 31, thereby adjusting the lateral distance between the side clamping plate 5 and the lower clamping plate 201.

[0034] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.

The method for assembling the three-dimensional adjustable steel structure positioning and assembling bracket according to claim 9, characterized in that: In step a, the longitudinal adjustment mechanism is adjusted by: the longitudinal drive motor drives the sprocket to rotate, and the longitudinal sliding vehicle and the side clamping plate are driven to move longitudinally through the sprocket chain transmission to achieve preliminary adjustment of the longitudinal position; After the longitudinal adjustment mechanism is adjusted, the longitudinal fine adjustment is performed through the fine adjustment mechanism. The fine adjustment drive motor drives the fine adjustment screw to rotate, converting the rotational motion into the lateral movement of the lower wedge block. The upper wedge block can only move up and down under the limit of the guide column and the guide seat. The lateral movement of the lower wedge block is converted into the up and down movement of the upper wedge block, thereby realizing the fine adjustment of the longitudinal displacement; The adjustment method of the lateral adjustment mechanism is: the lateral drive motor drives the lateral screw rod to rotate, and the rotational movement of the lateral screw rod is converted into the lateral movement of the lateral sliding vehicle, thereby adjusting the lateral distance between the side clamping plate and the lower clamping plate.
