Description

Technical Field

[0001] The invention belongs to the technical field of bridge engineering, and in particular relates to an electrical automation group control assembly device for a steel box girder. Background Art

[0002] With the rapid development of science and technology and urbanization, steel structure bridges have been rapidly applied and emerged in urban transportation construction due to their advantages such as light structure, high strength and convenient construction. Steel box girders occupy a pivotal position in steel structure bridges, and the electrical automation of the processing and manufacturing of steel box girders is particularly urgent.

[0003] At present, the processing and manufacturing of steel box girders mainly uses traditional steel frame as the mold for processing and manufacturing of steel box girders and provides the workers with working space under the plate. The longitudinal slope, transverse slope and pre-camber of the steel box girder are adjusted by setting different heights on the top surface of each node of the steel frame, so as to meet the longitudinal slope, transverse slope and pre-camber requirements of the steel box girder section required by the design drawings. The manufacturing problem of steel box girders for ramp bridges is the most prominent. After a section of beam is assembled and welded, when processing and manufacturing the next section of steel box girder, it is necessary to re-measure the top elevation of the original steel frame, and adjust the elevation of the node of the steel frame according to the comparison results of the measurement data, so as to meet the longitudinal slope, transverse slope and pre-camber requirements required for the assembly of the next section of steel box girder.

[0004] After each assembly and welding of a beam section is completed, the steel sections are cut to lower the elevation or welded to increase the elevation before the next beam section is operated. Since the cutting speed is higher than the welding speed, in actual operation, cutting to lower the elevation is mainly used. Therefore, the waste problem caused in the process of adjusting the elevation of the tire frame is particularly prominent. Summary of the invention

[0036] According to a first aspect of the present invention, see Figures 1 to 3 , provides a steel box girder electrical automation group control assembly device. The steel box girder electrical automation group control assembly device is to install a rack driven by a drive unit at each node end of the steel frame, and use group control technology to control the drive unit to accurately drive the rack to position and lock the state, so as to achieve the purpose of automatic assembly and shaping of the steel box girder.

[0037] Specifically, the electrical automation group control assembly device for steel box beams includes:

[0038] The support unit is provided with a plurality of nodes; the support unit includes a steel frame, which provides a working space for welding under the bottom plate of the steel box beam and a space for the extension and contraction of the rack;

[0039] A plurality of electrical units, each of the nodes corresponds to one electrical unit, each of the electrical units comprises a rack 2, a gear 3 and a driving unit, the gear 3 is mounted on the driving unit, and the rack 2 is meshed with the gear 3; the rack 2 is telescopically arranged at the node, and the top surface height of each node can be adjusted by controlling the telescopic height of each rack 2; that is, the top height of the rack 2 is used as the top surface height of the node;

[0040] A group control module and a plurality of controllers 5, wherein the plurality of controllers 5 are connected to the plurality of drive units one by one, and the plurality of controllers 5 are all connected to the group control module;

[0041] The group control module is used to control each driving unit through each controller 5 according to the design parameters of the steel box girder to adjust the telescopic height of each rack 2.

[0042] In the embodiment of the present application, the electrical automation group control assembly device for the steel box girder can input the design linear parameters of the steel box girder into the group control module, and calculate the expansion and contraction value of each rack 2 installed on each node of the support unit (that is, the steel frame) through the group control module, and convert each expansion and contraction value into a certain number of electric pulse signals. Then, the group control module sends instructions to each controller 5 connected to the drive unit to control each drive unit to accurately drive the rack 2 to make corresponding expansion and contraction according to the number and direction of the received electric pulse signals, so as to realize the electrical automation and accurate expansion and contraction of each rack 2, thereby adjusting the original fixed-elevation steel frame to an automatically adjustable and reusable steel frame, which significantly reduces the time, labor and material waste caused by adjusting the elevation of the steel frame during the assembly of the steel box girder, so that the assembly of the steel box girder can completely realize factory efficiency and integrated automation.

[0043] It should be noted that when the rack 2 is installed on a bracket unit (such as a steel frame), after the web linear parameters are set in the group control software (i.e., the group control module), the rack 2 is indirectly driven by the AC servo motor 42 to extrude the web to reach the designed deformation amount and then locked, which significantly improves the assembly efficiency of the web.

[0044] Optionally, the support unit includes a bottom plate type steel tire frame 11 and a plurality of web plate type steel tire frames 12;

[0045] The bottom plate type steel tire frame 11 is provided with a plurality of first nodes;

[0046] A second node is provided at the end of each of the web-type steel tire frames 12 .

[0047] In the above embodiment, the AC servo motor 42, the motor reducer 41 and the rack 2 are installed on each first node set on the bottom plate steel frame 11, and the AC servo motor 42, the motor reducer 41 and the rack 2 are installed on each second node set on the web plate steel frame 12. The group control software installed on the computer 6 controls each controller 5 to indirectly control the AC servo motor 42 to drive the rack 2 to extend and retract, so as to realize the electrical automation group control assembly of the steel box girder, avoid the waste caused by adjusting the elevation of the entire steel frame, and improve the assembly efficiency of the steel box girder.

[0048] Optionally, the rack 2 at the second node forms a preset angle with the extension direction of the web steel frame 12. This helps the rack 2 to quantitatively expand and contract according to the preset angle, and can squeeze the web steel plate of the steel box girder so that the web steel plate reaches the designed deformation amount under the control of the linear parameters.

[0049] Optionally, the driving unit includes a motor reducer 41 and an AC servo motor 42;

[0050] The motor reducer 41 is mounted on the output shaft of the AC servo motor 42 , and the gear 3 is mounted on the output shaft of the motor reducer 41 .

[0051] In the above embodiment, the lifting data parameters corresponding to each rack 2 are calculated through the group control module (such as group control software) and converted into the number of electric pulse signals through the group control module, and each group of electric pulse signals is transmitted to the corresponding AC servo motor 42 through the controller 5, so as to control the corresponding AC servo motor 42 to make a quantitative positive or negative rotation number of circles. The kinetic energy output by the corresponding AC servo motor 42 is reduced by the motor reducer 41 to increase the output torque and reduce the load inertia, and then acts on the corresponding rack 2, so that the corresponding rack 2 can accurately make a quantitative lifting or lowering action as the AC servo motor 42 controls the number of circles and the positive and negative directions of the gear 3. The lifting speed of the rack 2 is controlled at 10-35mm / min. After the corresponding lifting adjustment is completed, the motor gear 3 is locked to indirectly maintain the working state of the rack 2, thereby achieving the purpose of electrical automation group control to assemble steel box girders. Therefore, the electrical automation group control assembly device of the steel box girder adopts group control technology, which controls each rack 2 installed on the node of the steel frame, and the corresponding rack 2 is accurately extended and retracted according to the set parameters, thereby avoiding various wastes caused by adjusting the elevation of the steel frame and continuously cutting and welding the steel of the frame.

[0052] It should be noted that the rack 2 is installed at the node position of the steel frame. When the AC servo motor 42 drives the rack 2 to extend and retract through the motor reducer 41, each rack 2 can be extended and retracted independently to achieve the purpose of adjusting the elevation.

[0053] Optionally, the steel box girder electrical automation group control assembly device further includes a computer 6 and a data cable 7:

[0054] The group control module is installed on the computer 6 , and the computer 6 is connected to each of the controllers 5 via the data cable 7 .

[0055] In the above embodiment, the group control software installed on the computer 6 sends instructions to the controller 5 connected to the AC servo motor 42 to control the number and positive and negative directions of the electric pulse signals received by each AC servo motor 42 to drive the expansion and contraction of a single rack 2. For example, the design parameters such as the horizontal curve and vertical curve of the steel box girder are imported into the group control software, and the group control software is used to calculate the expansion and contraction of the rack 2 distributed at each node of the steel frame at equal intervals, so as to achieve the elevation adjustment from point to line and then to surface; when the rack 2 is installed on the web steel frame 12, the rack 2 is horizontally quantitatively expanded and contracted, which can squeeze the web steel plate of the steel box girder, so that the web steel plate reaches the designed deformation amount under the control of the linear parameters.

[0056] Optionally, the driving unit is fixed to the bracket unit, which makes the fixing method of the driving unit relatively simple and convenient for operation.

[0057] Optionally, the electrical automation group control assembly device for the steel box girder further includes a limit unit;

[0058] The limiting unit is installed on the bracket unit, and the rack 2 is installed on the limiting unit. The limiting unit is used to support and limit the rack 2.

[0059] In the above embodiment, the rack 2 can be supported and limited by the limiting unit, and the stability of the rack 2 during the extension and retraction process can be ensured.

[0060] Optionally, the limiting unit is a track slot, and part of the rack 2 is embedded in the track slot. The structural design of the limiting unit is relatively reasonable.

[0061] Optionally, the design parameters of the steel box girder are displayed on the display interface of the computer 6. This helps the staff to understand the design parameters of the steel box girder in a timely manner.

[0062] Optionally, the AC servo motor 42 is fixed to the motor reducer 41 by bolts, which makes the fixing method of the AC servo motor 42 and the motor reducer 41 relatively simple.

[0063] Exemplarily, the electrical automation group control assembly device for steel box girders includes an electrical system composed of an AC servo motor 42, a motor reducer 41 and a rack 2, a group control system composed of a controller 5, a group control module (i.e., group control software), a data cable 7 and a computer 6, and a bracket system composed of bracket units welded with section steel. The AC servo motor 42, the motor reducer 41 and the rack 2 are installed on each node of the section steel frame, and the controller 5 is installed on each AC servo motor 42. The group control software installed on the computer 6 controls each controller 5 to indirectly control the AC servo motor 42 to drive the rack 2 to extend and retract, so as to realize the electrical automation group control assembly of steel box girders, avoid the waste caused by adjusting the elevation of the entire section steel frame, and improve the assembly efficiency of steel box girders.

[0064] Therefore, the electrical automation group control assembly device for steel box girders integrates electrical automation and group control systems on the basis of the original steel frame, making the assembly of steel box girders quick and accurate, and eliminating the waste of time, materials and labor caused by adjusting the elevation of the steel frame, so that the assembly of steel box girders completely realizes factory efficiency and integrated automation.
