[0032] See also Figure 1 to Figure 8 The embodiment of the utility model discloses a bridge deck rib assembly device, which specifically includes: a crossbeam 1, a longitudinal movement mechanism 2, a clamping mechanism 3, a transverse movement mechanism 4, a clamping mechanism 5 and a platform 6; wherein the crossbeam 1 is horizontally arranged above the platform 1 and is arranged perpendicular to the length direction of the rib; the longitudinal movement mechanism 2 is arranged on both sides of the platform 6, and the two ends of the crossbeam 1 are fixed on the longitudinal movement mechanism 2, and the crossbeam 6 is driven to move longitudinally by the longitudinal movement mechanism 2.
[0033] The clamping mechanism 3 is slidably connected to the bottom of the beam 1 , and the transverse movement mechanism 4 is installed on one side of the clamping mechanism 3 , and the clamping mechanism 3 is driven by the transverse movement mechanism 4 to move along the bottom of the beam 1 .
[0034] The clamping mechanism 5 is installed below the pressing mechanism 3. The plate ribs are accurately positioned on the bridge deck by clamping the plate ribs to the left and right and pressing the plate ribs downward by the clamping mechanism 5.
[0035] Specifically, the longitudinal movement mechanism 2 includes a track 2-1 fixed on both sides of the platform 6 and a driving trolley 2-2 arranged on the track 2-1 and capable of moving along the track 2-1. The two ends of the beam 1 are fixedly connected to the driving trolley 2-2. The driving trolley 2-2 is electrically connected to the electric control cabinet 2-3 arranged at the upper end of the beam 1, and is controlled by the electric control cabinet 2-3 to move along the track 2-1, thereby driving the beam 1 to move forward or backward. In addition, the motor housing of the motor used in the driving trolley 2-2 is selected to be variable frequency and with power-off automatic brake function, and the speed is adjustable to meet the speed adjustment of the driving trolley, and the power-off brake can omit the trolley locking device.
[0036] In addition, in order to ensure that the driving trolley 2-2 can move stably, a pair of rollers 2-5 are fixed to the bottom of the driving trolley 2-2 through a mounting frame 2-4, and the rollers 2-5 are clamped on both sides of the track 2-1 to guide the driving trolley 2-2 to prevent the driving trolley 2-2 from running off the track.
[0037] Furthermore, the clamping mechanism 3 includes a plurality of clamping boxes 3-1, a pair of guide rails 1-1 are arranged at the bottom of the beam 1, and the clamping box 3-1 is slidably connected to the guide rails 1-1 through a pair of sliders 3-2 arranged at the upper end thereof, and a hydraulic cylinder 3-3 is vertically arranged in the center of the clamping box 3-1, and a connecting plate 3-4 is horizontally fixed after the piston rod of the hydraulic cylinder 3-3 extends downward from the bottom of the clamping box 3-1, and the hydraulic cylinder 3-3 is electrically connected to a hydraulic pump station 3-5 arranged at the upper end of the beam 1 through a hydraulic pipeline, and the operation of the hydraulic cylinder 3-3 is controlled by the hydraulic pump station 3-5.

[0044] The specific working process of the plate rib assembly device is as follows:
[0045] When it is necessary to assemble the plate rib 9, the driving trolley 2-2 is controlled to move to the predetermined position along the length direction of the plate rib unit, and the motor of the driving trolley 2-2 is powered off and the brake is locked, so that the entire device is fixed; then the reduction motor 4-2 is started, so that the reduction motor 4-2 drives the gear 4-1 to rotate, and drives the entire clamping mechanism 3, the transverse mechanism 4 and the clamping mechanism 5 to move through the meshing transmission with the rack 1-2, so that the clamping mechanism 5 is located directly above one end of the plate rib (the end has been spot welded in advance), and the reduction motor 4-2 is powered off and the brake is locked, so that the clamping mechanism 3, the transverse mechanism 4 and the clamping mechanism 5 are fixed; at this time, the piston rod of the hydraulic cylinder 3-3 of the clamping mechanism 3 above the plate rib to be assembled is controlled to extend, driving the clamping mechanism 5 to move downward so that the plate rib 9 is placed between the clamping roller 5-1 and the fixed roller 5-2, and by adjusting the position of the clamping roller frame 5-3, the clamping roller frame 5-3 is The wheel 5-1 and the fixed roller 5-2 clamp the plate rib 9, and then the screw 8-1 in the clamping adjustment assembly 8 is rotated according to the height of the plate rib, so that the clamping head 8-2 is pressed against the plate rib, and at the same time, the piston rod of the hydraulic cylinder 3-3 of the clamping mechanism 3 of the bridge deck 10 above the plate rib to be assembled is further extended, so that the clamping head 8-2 presses the plate rib tightly on it (the bridge deck 10 is placed on the platform 6). After the plate rib 9 is clamped and clamped, the workers can fix it by electric welding; after the spot welding at this location is completed, the hydraulic cylinder 3-3 is controlled so that its piston rod drives the clamping mechanism 5 to lift, so that the clamping head 8-2 moves up, and then the driving trolley 2-2 is controlled to continue to move forward along the track 2-1 to a spot welding point under the plate rib, and the position of the clamping head 8-2 and the position of the piston rod of the hydraulic cylinder 3-3 are adjusted, so that the clamping head 8-2 presses the plate rib 9 tightly on the bridge deck 10, and spot welding is performed until the spot welding of the entire plate rib assembly is completed. During assembly, the transverse movement mechanism 4, the clamping mechanism 3 and the clamping mechanism 5 can be increased or decreased according to the actual number of plate ribs, or the redundant transverse movement mechanism 4, the clamping mechanism 3 and the clamping mechanism 5 can be moved to the non-working area through the transverse movement mechanism 4 for avoidance.
[0046] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
