[0021] The lifting member includes a third hydraulic cylinder 43 disposed inside the base frame 41, and the telescopic end of the third hydraulic cylinder 43 abuts against the outer surface of the Y-shaped steel 4; like Figure 1 and Fig.11 As shown, the third hydraulic cylinder 43 can lift the Y-shaped steel 4 so that the Y-shaped steel 4 can fit the grinding mechanism for grinding.

[0022] The clamping member includes a support seat 39 fixedly arranged on the outside of one of the bottom frames 41, a second two-way telescopic cylinder 40 is fixedly arranged on the outer surface of the support seat 39, and clamping blocks 42 are fixedly arranged at both ends of the second two-way telescopic cylinder 40, and two groups of clamping blocks 42 are respectively against the outer walls of both sides of the Y-shaped steel 4; like Fig. 9 and Fig.10 As shown, under the connection of the support seat 39, the second bidirectional telescopic cylinder 40 is stably arranged above one group of base frames 41 for use. The second bidirectional telescopic cylinder 40 can drive two groups of clamping blocks 42 to clamp the two side surfaces of one end of the Y-shaped steel 4, thereby ensuring that the Y-shaped steel 4 can be more stable during the processing.

[0023] The walking mechanism includes a support arm 38, and connecting arms 35 are provided on both sides of the outer wall of the support arm 38, and the two ends of the two connecting arms 35 are rotatably installed with a clamping rod 34, and the lower outer side of the clamping rod 34 is rotatably installed with a wheel 36, the connecting arm 35 is located above the external frame 1, and the two sets of wheels 36 on the same side are respectively rolled and pressed against the inner and outer surfaces of the external frame 1, and a connecting shaft 37 is rotatably inserted in the support arm 38 and away from the end of the connecting arm 35, and a travel motor 7 is installed on the upper end of the connecting shaft 37, and the outside of the travel motor 7 is fixedly set on the outer surface of the L-shaped rod 11 through a set of clamping plates, and a meshing gear 32 is fixedly set on the lower outer side of the connecting shaft 37, and the meshing gear 32 is meshed and connected with the rotating rack 33; like Figure 8 and Fig. 9 As shown, under the connection of the support arm 38, the two sets of connecting arms 35 assemble the wheels 36 that are stuck on the inner and outer surfaces of the external frame 1, and then when the walking motor 7 drives the connecting shaft 37 to rotate, the meshing gear 32 is meshed and connected with the rotating rack 33, and moves to the outside of the rotating rack 33 and the external frame 1, so that during grinding, it can fully contact with the Y-shaped steel 4 in turn, thereby improving the grinding efficiency.

[0024] The telescopic mechanism includes a second hydraulic cylinder 22 fixedly installed inside the L-shaped seat 6 and close to one end of the L-shaped rod 11. The telescopic end of the second hydraulic cylinder 22 is fixedly connected to the outer wall of the sleeve 20. The elastic pressure member includes a slide rod 18 slidably installed inside the sleeve 20. The end of the slide rod 18 outside and away from the sleeve 20 is fixedly connected to the fixed rod 17. The spring 21 is sleeved outside the slide rod 18 and located between the fixed rod 17 and the sleeve 20. The lower end of the fixed rod 17 is fixedly provided with a bottom rod 8. The end of the bottom rod 8 away from the slide rod 18 is fixedly provided with a rotating table 16. The grinding mechanism is arranged above the rotating table 16. like Figure 3 and Figure 4 As shown, when the grinding mechanism cooperates with the support arm 38 to move outside the external frame 1, it contacts different areas of the Y-shaped steel 4 in sequence, and the spring 21 can satisfy the grinding mechanism in the flat area, so that the vertical grinding rod 14 always fits the side wall of the Y-shaped steel 4; The second hydraulic cylinder 22 compensates for the use of the spring 21. When the grinding mechanism passes through the V-shaped end and the V-shaped inner angle of the Y-shaped steel 4, the grinding mechanism is adjusted to be able to fully contact the Y-shaped steel 4 during the rotation process through telescopic adjustment.

[0025] The bottom rod 8 and the rotating platform 16 can improve the stability of the grinding mechanism and cooperate with the grinding mechanism to rotate inside.

[0026] The grinding mechanism includes a driving shaft 15 rotatably mounted on the upper part of the rotating table 16, a vertical grinding rod 14 is sleeved in the middle of the outer side of the driving shaft 15, a first bevel gear 13 is fixedly sleeved on the outer side of the driving shaft 15 and located above the vertical grinding rod 14, a rotating motor 9 is mounted on the upper end of the driving shaft 15, a mounting sleeve 12 is sleeved on the outer side of the rotating motor 9, and the outer side of the mounting sleeve 12 is connected to the upper surface of the bottom rod 8 through a fixedly arranged frame rod; like Figure 3 As shown, the rotating motor 9 can drive the driving shaft 15 to rotate, thereby allowing the vertical grinding rod 14 and the first bevel gear 13 to rotate synchronously, and the vertical grinding rod 14 can grind the side wall of the Y-shaped steel 4, and the first bevel gear 13 is meshed and connected with the second bevel gear 30 set on one side; The mounting sleeve 12 and the mounting rod facilitate the installation of the rotary motor 9 above the vertical grinding rod 14 for use.

[0027] A fixing frame 31 is fixedly arranged at one end of the mounting sleeve 12 away from the frame rod, an L-shaped frame 10 is fixedly arranged on the upper surface of the fixing frame 31, a dust removal mechanism is arranged inside the end of the L-shaped frame 10 away from the fixing frame 31, a rotating shaft 29 is rotatably inserted inside the fixing frame 31, a transverse grinding rod 28 is sleeved on the outer side of the rotating shaft 29, a second bevel gear 30 is arranged outside the rotating shaft 29 and at one end of the transverse grinding rod 28, and the second bevel gear 30 is meshed and connected with the first bevel gear 13; like Figure 7As shown, under the connection of the L-shaped frame 10, the dust removal mechanism can be arranged above one side of the fixed frame 31 for use, thereby absorbing the dust after grinding, thereby reducing the flying of dust during the processing; When the second bevel gear 30 on the outside of the rotating shaft 29 is meshed with the first bevel gear 13, the rotating shaft 29 can drive the horizontal grinding rod 28 to rotate, so that during the movement, the horizontal grinding rod 28 and the vertical grinding rod 14 can grind two areas of the Y-shaped steel 4 at the same time, further improving the efficiency of grinding and rust removal.

[0028] A first hydraulic cylinder 5 is fixedly arranged inside one end of the L-shaped frame 10 away from the fixed frame 31, and a storage rack 24 is fixedly arranged at the telescopic end of the first hydraulic cylinder 5. Vacuum cleaners 23 are rotatably installed on both sides of the storage rack 24. A rotating seat 25 is fixedly arranged on the outer surface of the side where the two groups of vacuum cleaners 23 are close to each other. The two groups of rotating seats 25 are rotatably connected by a first bidirectional telescopic cylinder 26, and the outer side of the first bidirectional telescopic cylinder 26 is fixedly arranged on the lower surface of the storage rack 24 through a fixed block 27; like Figure 1 , Figure 5 and Figure 6 As shown, the telescopic drive of the first hydraulic cylinder 5 can drive the rack 24 to move up and down, and can be adjusted for use during vacuuming; Under the telescopic drive of the first two-way telescopic cylinder 26, the two sets of rotating seats 25 cooperate with the drive of the first two-way telescopic cylinder 26 and rotate together to adjust the suction angles of the two sets of vacuum cleaners 23, thereby fully meeting the dust collection needs of the vertical grinding rod 14 and the horizontal grinding rod 28.

[0029] Working principle: When in use, first place the Y-shaped steel 4 above the two groups of third hydraulic cylinders 43, and one end of the Y-shaped steel 4 is driven by the second two-way telescopic cylinder 40 at one end, so that the two groups of clamping blocks 42 are clamped on the outer walls on both sides of one end of the Y-shaped steel 4. Combined with the weight of the Y-shaped steel 4 itself, the Y-shaped steel 4 is stably placed above the stand 2 for processing, and then driven by the third hydraulic cylinder 43, the Y-shaped steel 4 can be lifted, so that the outer surface of one side of the Y-shaped steel 4 contacts the horizontal grinding rod 28, and the side wall contacts the vertical grinding rod 14, and then the travel motor 7 is started. The meshing gear 32 at the lower connecting shaft 37 is driven to rotate. Under the rolling limit of the supporting arm 38 and the two sets of rolling cards against the inner and outer surfaces of the external frame 1, the meshing gear 32 can cooperate with the rotating rack 33 and move on the outer surface of the rotating rack 33. At the same time, the rotating motor 9 is started to drive the driving shaft 15 to rotate, and the vertical grinding rod 14 and the first bevel gear 13 rotate synchronously. The first bevel gear 13 is meshed and connected with the second bevel gear 30, thereby prompting the horizontal grinding rod 28 to rotate synchronously. During the process of moving, the side wall and surface of the Y-shaped steel 4 are successively polished. When grinding and rust removal is performed and moving to the special shape of the Y-shaped steel 4, the vertical grinding rod 14 will cause the spring 21 to be compressed toward the sleeve 20 under the connection of the fixed rod 17 and the sliding rod 18, so that the vertical grinding rod 14 can always fit the side wall when grinding the Y-shaped steel 4. The spring 21 can adapt to the gentle curved surface area of ​​the Y-shaped steel 4 under the elastic expansion and contraction. When moving to the V-shaped end of the Y-shaped steel 4, the second hydraulic cylinder 22 needs to cooperate with the pulling sleeve 20, thereby causing the sliding rod 18, the U-shaped seat 19, and the fixed rod 17 to move backward like one end, and then during the rotation process, Ensure that the vertical grinding rod 14 has a certain distance to extend so that the Y-shaped steel 4 can be derusted under the setting of the rotating rack 33. Similarly, when the support arm 38 moves to the V-shaped inner corner of the Y-shaped steel 4, in order to ensure that the vertical grinding rod 14 can contact the inner corner area to the greatest extent, the second hydraulic cylinder 22 needs to be pushed forward to allow the vertical grinding rod 14 to contact the inner corner area, thereby ensuring that the Y-shaped steel 4 is fully adapted for processing. After completing the grinding work, the worker only needs to spray the preservative at the end to ensure the stability of the Y-shaped steel 4 when it is used as a bridge support structure in the later stage.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only the features of the present invention.
