Abstract

The invention belongs to the technical field of steel structure bridge construction, and relates to a steel structure bridge workshop primer rapid grinding device, which comprises a power device, a transmission device and a grinding device, wherein the power device is connected with the transmission device to drive the grinding device, and the grinding device completes grinding and polishing. Weld joints of stiffening ribs of steel bridge top and bottom plate unit pieces are prone to fatigue cracks due to dynamic loads, so that in order to guarantee the welding quality of the stiffening ribs and the weld joints of the top and bottom plates, the weld joints of the stiffening ribs of the top and bottom plates need to be polished in advance to have metal luster, the distance between the stiffening ribs in the plate unit pieces is generally small, and the weld joints are dense, in the prior art, a traditional manual grinding wheel angle grinder wastes time and labor during grinding, and serious pollution can be generated. The steel structure bridge workshop primer rapid grinding device provided by the invention has the beneficial effects that the labor efficiency is improved, the labor cost is saved, meanwhile, pollution is reduced, the construction period is greatly shortened, and a good foundation is laid for engineering green construction, quality improvement and efficiency improvement.

Example Embodiment

[0027] Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0028] In the embodiment of the present invention, if image 3 As shown, the production process of the primer grinding device of the steel structure bridge workshop is, the lower plate cuts a rectangular steel sheet having a thickness of 16 to 20 mm as the working base plate 15 of the device, and the working base plate 15 is based on the operating shaft 9, the motor shaft 5 and the motor 4 and the drive shaft spacing calculation determine, and the lower plate cuts a steel sheet 19 having a thickness of the working base plate, which is the same but the length is slightly larger than the working base plate as the line base plate 19; cutting production two working axis bottom plates Part 11, such as Figure 5 As shown, the connector is centrally opened, and the connecting bearing 12 is mounted to connect the operating shaft 9;
[0029] The working base plate 15 is opened according to the motor 4 mounting position according to the motor 4 to connect the motor base 18, and the working shaft bottom plate connecting member 11 is mounted according to the working shaft 9; the cutting production is slightly larger than the rounded width. The steel is used as the travel axle 17 of the device, and the respective diameter rollers 16 are mounted on both ends of the axle; the traveling wheel shaft 17 is fixed to the lower part of the traveling base plate 19; the working base plate 15 and the travel base plate 19 are connected to the base plate connector 20 After connecting the active wheel 6 and the driven wheel 8, the working shaft 9 is fixed through the working base plate connector 1 and is fixed with the connecting bearing 12, and the drive wheel 6 is fixed to one end of the motor shaft 5 with the bearing fixture 22. The driven wheel 8 is fixed to one end of the working shaft 9, and it needs to be tightly detected in the position of each other, ensuring the driven wheel and the drive belt on one line.
[0030] At the other end of the working shaft 9, the grinding device is mounted, the grinding device is polished, and the relative angle of the thousand blades is tightly adjusted, and then the bearing fixation fitting 22 is fixed; and the upper portion of the polished thousand blade 21 is installed The sheet protective cover 10 and the hand push rod 13 is welded to the working chassis 15.
[0031] The work step of the construction device of the embodiment of the present invention, such as figure 1 , 2 As shown, in the top floor U (I) rib 2 assembles the welding position, the center of the polished thousand blade 21 is aligned with the centerline of the polishing position; press down to press the crossbar 14, so that the polished thousand blades 21 Steel plate surface contact; push the primer grinding device walk along the painted line, polished thousand blades 21 high speed rotation and steel plate friction, the friction causes the route that the device can travel to the metal gloss, polished; final assembled U (I) type rib.
[0032] The construction technique of the present invention uses a small motor to drive the transmission to drive the polished thousand blades high-speed rotation and steel plate friction. With the polishing thousand blades and steel sheets, the mold is grinded off and weld the top plate unit U (I) ribs. The seam welding portion has a metal gloss; the embodiment of the present invention is simple, high in grinding quality, and greatly improves the efficiency of the primer wear, reducing artificial cost and effectively shortening the construction period.
[0033] The embodiments of the present invention have been described in detail above, but the content is only the preferred embodiment of the present invention, and cannot be considered to be used to limit the scope of the invention. All equal changes and improvements in the scope of the invention are still within the scope of the patent coverage of the invention.
