[0003] At present, the steel box girder processing and manufacturing mainly uses the traditional section steel jig frame as the mold of the steel box girder processing and manufacturing and provides the under-plate operation space for the operating personnel, the different heights set on the top surface of each node of the section steel jig frame are used to adjust the longitudinal slope, transverse slope and pre-camber of the steel box girder, so as to meet the longitudinal slope, transverse slope and pre-camber requirements of the steel box girder beam section required by the design drawing, and the steel box girder manufacturing problem of the ramp bridge is most prominent. When a beam section is set and welded, the top elevation of the original section steel jig frame needs to be re-measured before the processing and manufacturing of the next steel box girder beam section, and the elevation of the node part of the section steel jig frame is adjusted according to the comparison result of the measurement data, so that the longitudinal slope, transverse slope and pre-camber required when the next steel box girder beam section is set are met.

[0034] According to the first aspect of the present application, referring to Figs. 1 to 3 , a steel box girder electric automatic group control assembly device is provided. The steel box girder electric automatic group control assembly device is achieved by installing a rack driven by a driving unit at each node end of the section steel jig frame, using group control technology to control the driving unit to accurately drive the rack to position and lock the state, to achieve the purpose of automatic assembly and shaping of the steel box girder.

[0035] Specifically, the steel box girder electric automatic group control assembly device comprises:

[0036] The support unit is provided with a plurality of nodes, including a first node and a second node; the support unit includes a bottom plate type steel jig 11 and a plurality of web type steel jigs 12; the bottom plate type steel jig 11 is provided with a plurality of first nodes; each of the web type steel jigs 12 is provided with a second node; the support unit includes a steel jig, and the steel jig provides a working space for welding of a steel box girder bottom plate and a space for rack extension;

[0037] A plurality of electrical units, each of the nodes corresponds to one of the electrical units, each of the electrical units includes a rack 2, a pinion 3 and a driving unit, the pinion 3 is installed on the driving unit, and the rack 2 is engaged with the pinion 3; the rack 2 is telescopically arranged at the node, and the height of the top surface of each node can be adjusted by controlling the extension height of each rack 2, that is, the height of the top point of the rack 2 serves as the height of the top surface of the node; the rack 2 located at the first node is distributed in the vertical direction, and the rack 2 located at the second node is distributed in the horizontal direction;

[0038] A group control module and a plurality of controllers 5, the plurality of controllers 5 are connected with the plurality of driving units one by one, and the plurality of controllers 5 are connected with the group control module;

[0039] The group control module is used for adjusting the extension height of each rack 2 by controlling each driving unit through each controller 5 according to the design parameters of the steel box girder.

[0040] In the embodiment of the present application, the steel box girder electrical automation group control assembly device can input the design linear parameters of the steel box girder into the group control module, calculate the extension value of each rack 2 distributed on each node of the support unit (i.e. the steel jig), convert each extension value into a certain number of electric pulse signals, then send instructions from the group control module to each controller 5 connected to the driving unit, control each driving unit to accurately drive the rack 2 to make corresponding extension according to the number and direction of the received electric pulse signals, so as to realize the electrical automation accurate extension of each rack 2, thereby adjusting the original fixed elevation steel jig to a cyclically used steel jig, and significantly reducing the time, labor and material waste caused by adjusting the elevation of the steel jig during the assembly of the steel box girder, so that the assembly of the steel box girder is completely realized with high efficiency and integrated automation in the factory.

[0041] It should be noted that when the rack 2 is installed on the support unit (such as the steel jig), after the web linear parameters are set in the group control software, the rack 2 is indirectly driven by the alternating current servo motor 42 to extrude the web to achieve the design variation amount and then locked, which significantly improves the assembly efficiency of the web.

[0042] Exemplarily, the AC servo motor 42, the motor reducer 41 and the rack 2 are installed on each first node arranged by the bottom plate type steel rack 11, and the AC servo motor 42, the motor reducer 41 and the rack 2 are installed on each second node arranged by the web plate type steel rack 12, and the extension and retraction of the rack 2 driven by the AC servo motor 42 are indirectly controlled by each controller 5 through the group control software installed on the computer 6, so as to realize the electric automatic group control assembly of the steel box girder, avoid the waste caused by the elevation of the whole steel rack and improve the assembly efficiency of the steel box girder.

[0043] Optionally, the bottom plate type steel rack 11 and the web plate type steel rack 12 are welded by the steel. This makes the formation of the bottom plate type steel rack 11 and the web plate type steel rack 12 convenient and simple.

[0044] Optionally, the racks 2 located at the second nodes are distributed along the extension direction of the web plate type steel rack 12. That is, the web plate type steel rack 12 is distributed along the horizontal direction. This helps the racks 2 to quantitatively extend and retract in the horizontal direction, so as to extrude the web plate of the steel box girder and make the web plate reach the design variation amount under the control of the linear parameters.

[0045] In other embodiments, the racks 2 located at the second nodes are at a preset angle with the extension direction of the web plate type steel rack 12. This helps the racks 2 to quantitatively extend and retract at the preset angle, so as to extrude the web plate of the steel box girder and make the web plate reach the design variation amount under the control of the linear parameters.

[0048] In the above embodiment, the lifting data parameters corresponding to each rack 2 are calculated by the group control module (for example, group control software), and are converted into the number of electric pulse signals by the group control module. Each group of electric pulse signal numbers 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 number of rotations in the positive or reverse direction. The kinetic energy output by the corresponding AC servo motor 42 is reduced in speed, increased in output torque and reduced in load inertia through the motor reducer 41, and then acts on the corresponding rack 2. The corresponding rack 2 accurately makes a quantitative lifting or lowering action according to the number of rotations and the positive or reverse direction of the gear 3 controlled by the AC servo motor 42, and the lifting speed of the rack 2 is controlled at 10-35 mm / min. After the corresponding lifting adjustment is completed, the gear 3 is locked, so as to indirectly keep the working state of the rack 2, thereby achieving the purpose of electrically and automatically controlling the group assembly of the steel box girder. Therefore, the steel box girder electrically and automatically controlled group assembly device adopts group control technology, controls each rack 2 installed on the node of the steel frame, and the corresponding rack 2 accurately stretches and contracts according to the set parameters, so as to avoid various wastes caused by continuously cutting and welding the steel of the steel frame due to the adjustment of the elevation of the steel frame.

[0049] It should be noted that the rack 2 is installed on the node of the steel frame. When the AC servo motor 42 drives the rack 2 to stretch and contract through the motor reducer 41, each rack 2 can independently stretch and contract, so as to achieve the purpose of adjusting the elevation.

[0050] Optionally, the steel box girder electrically and automatically controlled group assembly device further comprises a computer 6 and a data line 7.

[0051] The group control module is installed on the computer 6, and the computer 6 is connected with each controller 5 through the data line 7.

[0052] In the above embodiment, the group control software installed on the computer 6 sends instructions to the controller 5 connected with the AC servo motor 42, controls the number and the positive or reverse direction of the electric pulse signals received by each AC servo motor 42, and drives the stretching and contracting amount of the single rack 2. For example, the design parameters such as the design horizontal curve and the vertical curve of the steel box girder are introduced into the group control software. The group control software calculates the stretching and contracting amount of the rack 2 distributed at equal intervals on each node of the steel frame, so as to realize 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 performs horizontal quantitative stretching and contracting, can extrude the web steel plate of the steel box girder, and makes the web steel plate reach the design variation amount under the control of the linear parameter.

[0053] Optionally, the driving unit is fixed to the support unit. This makes the fixing mode of the driving unit simple and convenient to operate.

[0054] Optionally, the steel box girder electrically and automatically controlled group assembly device further comprises a limiting unit.

[0055] The limiting unit is installed on the support unit, and the rack 2 is installed on the limiting unit, and the limiting unit is used for supporting and limiting the rack 2.

[0056] In the above embodiment, the limiting unit can support and limit the rack 2, and can ensure the stability of the extension and contraction process of the rack 2.

[0057] Optionally, the limiting unit is a track sliding groove, and part of the rack 2 is embedded in the track sliding groove. The structure design of the limiting unit is reasonable.

[0058] Optionally, the design parameters of the steel box girder are displayed on the display interface of the computer 6. This helps the staff to know the design parameters of the steel box girder in time.

[0059] Optionally, the alternating current servo motor 42 is fixed with the motor reducer 41 through bolts. This makes the fixing mode of the alternating current servo motor 42 and the motor reducer 41 relatively simple.

[0060] Exemplarily, the steel box girder electrical automation group control assembly device comprises an electrical system composed of the alternating current servo motor 42, the motor reducer 41 and the rack 2, a group control system composed of the controller 5, the group control module (i.e. the group control software), the data line 7 and the computer 6, and a support system composed of the support unit welded by the sectional steel. The alternating current servo motor 42, the motor reducer 41 and the rack 2 are installed on each node of the sectional steel jig frame, the controller 5 is installed on each alternating current servo motor 42, each controller 5 is controlled through the group control software installed on the computer 6 to indirectly control the alternating current servo motor 42 to drive the rack 2 to extend and contract, so as to realize the steel box girder electrical automation group control assembly, avoid the waste caused by adjusting the elevation of the sectional steel jig frame, and improve the assembly efficiency of the steel box girder.

[0061] Therefore, the steel box girder electrical automation group control assembly device integrates electrical automation and group control system on the basis of the original sectional steel jig frame, makes the steel box girder assembly quick and accurate, saves the time, material and labor waste caused by adjusting the elevation of the sectional steel jig frame, and realizes the factory high efficiency and integrated automation of the steel box girder assembly.
