DETAILED DESCRIPTION

[0024] The utility model will be further explained in detail in combination with the drawings.

[0025] As shown in Figure 1 A steel pipe inner wall cleaning device, comprising a plurality of transmission mechanisms 1, a bearing mechanism 4, a material pouring mechanism 5 and an inner wall brushing mechanism 6.

[0026] As shown in Figure 1 , Figure 2 A plurality of transmission mechanisms 1 are arranged on the ground at intervals and are used for supporting and transmitting the steel pipes. The transmission mechanism 1 comprises a transmission seat 11, a transmission table 12, a driving transmission wheel 13 and a driven transmission wheel 14. The transmission seat 11 is vertically arranged on the ground and has an included angle of 10°-20° between the center line and the steel pipe running direction.

[0027] As shown in Figure 1 , Figure 2As shown, the transmission table 12 is horizontally arranged on the transmission base 11, one end of the transmission table 12 is rotatably connected to the transmission base 11, a cylinder 15 is rotatably connected to the transmission base 11, and the piston rod of the cylinder 15 is rotatably connected to the other end of the transmission table 12.

[0028] As shown in Figure 1 , Figure 2 , the driving transmission wheel 13 and the driven transmission wheel 14 are arranged side by side on both sides of the transmission table 12, and the outer wall of the driving transmission wheel 13 is tapered towards the direction of travel. The outer wall of the driven transmission wheel 14 is tapered towards the direction of travel, so as to automatically push the steel pipe to rotate forward when rotating.

[0029] When the steel pipe needs to be transmitted, the steel pipe is located between the driving transmission wheel 13 and the driven transmission wheel 14, at this time the driving transmission wheel 13 rotates, and the driven transmission wheel 14 rotates synchronously with the steel pipe. Since the driving transmission wheel 13 and the driven transmission wheel 14 are arranged with one end large and the other end small, and the large and small ends are opposite in direction, and there is an angle between the entire transmission mechanism 1 and the transmission direction of the steel pipe, so during the rotation of the driving transmission wheel 13 and the driven transmission wheel 14, the steel pipe can be controlled to rotate and advance at the same time, thereby realizing the stable transmission of the steel pipe.

[0030] Since the transmission table 12 is rotatably connected to the transmission base 11, in the actual working process, the transmission table 12 can be controlled to be tilted by the cylinder 15, so as to adjust the angle of the transmission table 12, thereby adapting to steel pipes of different thicknesses, and the inclination angle of the transmission table 12 can also adjust the transmission rate of the steel pipe, so as to meet different transmission requirements.

[0031] As shown in Figure 1 , Figure 3 , the bearing mechanism 4 includes a first bearing assembly 41 and a second bearing assembly 42, the first bearing assembly 41 and the second bearing assembly 42 are arranged side by side and are used to bear the steel pipe, the first bearing assembly 41 is located behind the last transmission mechanism 1, and the second bearing assembly 42 is lower than the first bearing assembly 41.

[0032] As shown in Figure 1 , Figure 3 , the first bearing assembly 41 and the second bearing assembly 42 each include a plurality of bearing seats 43 and bearing wheels 44, the bearing seats 43 are vertically and spaced apart on the ground, and the bearing wheels 44 are arranged in pairs and are rotatably connected to the bearing seats 43 and are used to support the steel pipe.

[0033] As shown in Figure 1 , Figure 3As shown, the material feeding mechanism 5 is used to guide the steel pipe from the first bearing assembly 41 to the second bearing assembly, and the inner wall cleaning mechanism 6 is arranged at both ends of the second bearing assembly and used to clean the inner wall of the steel pipe. The material unloading mechanism 7 is used to unload the cleaned steel pipe from the bearing mechanism 4.

[0034] As shown in Figure 1 , Figure 3 , the material feeding mechanism 5 comprises a plurality of material feeding frames 51, which are arranged side by side between the first bearing assembly 41 and the second bearing assembly 42 and higher at one end close to the first bearing assembly 41 than at the other end, and the lowest end of the material feeding frame 51 is provided with a material feeding stop rod 52.

[0035] As shown in Figure 1 , Figure 3 , the material feeding frame 51 is provided with a material feeding support 53 on both sides, which is located between two adjacent bearing seats 43. The material feeding support 53 is rotatably connected with a material feeding plate 54, which is arranged in an L shape and the side used to contact the steel pipe after being turned over is arranged in an inclined downward manner.

[0036] As shown in Figure 1 , Figure 3 , the material feeding plate 54 on one side is used to lift the steel pipe on the first bearing assembly 41 after being turned over and make the steel pipe automatically roll over the material feeding frame 51. The material feeding plate 54 on the other side is used to lift the steel pipe at the lower end of the material feeding frame 51 after being turned over and make the steel pipe automatically roll over the second bearing assembly 42.

[0037] When the steel pipe is transmitted to the first bearing assembly 41, the material feeding plate 54 close to the first bearing assembly 41 is controlled to rotate by the hydraulic cylinder close to the first bearing assembly 41, at this time, the material feeding plate 54 is turned over from horizontal to vertical, and the material feeding plate 54 lifts the steel pipe. Since the material feeding plate 54 is inclined, the steel pipe will automatically roll to the lowest end of the material feeding plate 54 and be blocked by the bending position, and at this time, the steel pipe is located directly above the upper end of the material feeding frame 51.

[0038] Then, the material feeding plate 54 is controlled to rotate reversely, at this time, the material feeding plate 54 is turned over from vertical to horizontal, and the material feeding plate 54 gradually lowers the steel pipe, and finally makes the steel pipe be accurately placed at the upper end of the material feeding frame 51, and then the steel pipe rolls along the material feeding frame 51 from top to bottom, and when the steel pipe automatically rolls to the lowest end of the material feeding frame 51, it is blocked by the material feeding stop rod 52, thereby realizing the positioning of the steel pipe.

[0039] Then, the material feeding plate 54 close to the second bearing assembly 42 is controlled to rotate by the hydraulic cylinder close to the second bearing assembly 42, at this time, the material feeding plate 54 is turned over from horizontal to vertical, and the material feeding plate 54 lifts the steel pipe.

[0040] Since the inclined surface is provided on the material reversing plate 54, the steel pipe will automatically roll to the lowest end position of the material reversing plate 54 and be blocked by the bending position, and at this time, the steel pipe is located directly above the upper end position of the second bearing assembly 42.

[0041] Then, the material reversing plate 54 is controlled to rotate reversely, at this time, the material reversing plate 54 is turned from vertical to horizontal, and the material reversing plate 54 gradually lowers the steel pipe, and finally the steel pipe is accurately placed on the second bearing assembly 42, realizing automatic material reversing of the steel pipe.

[0042] As shown in Figure 1 , Figure 4 , the inner wall cleaning mechanism 6 includes a cleaning seat 61, a cleaning pipe 62, a cleaning head 63, a walking vehicle 64 and a sewage pool 65. The cleaning seat 61 is distributed at both ends of the second bearing assembly 42, the cleaning pipe 62 is horizontally slidably arranged in the cleaning seat 61 and is used for inserting into both ends of the steel pipe. The cleaning head 63 is arranged at the end position of the cleaning pipe 62 and is used for abutting against the inner wall of the steel pipe.

[0043] As shown in Figure 1 , Figure 4 , the walking vehicle 64 is slidably connected to the cleaning seat 61 and is used for controlling the horizontal sliding of the cleaning pipe 62, and the sewage pool 32 is located between the cleaning seat 61 and the second bearing assembly 42 and is located below the pipe opening position of the steel pipe.

[0044] When it is necessary to clean the inner wall of the steel pipe, the walking vehicle 64 is used to control the synchronous sliding of the cleaning pipe 62 and the cleaning head 63, and the end position of the cleaning pipe 62 is inserted into the steel pipe, at the same time, the second bearing assembly 42 is used to control the rotation of the steel pipe position, and the walking vehicle 64 is used to control the slow travel of the cleaning pipe 62 and the cleaning head 63.

[0045] At this time, the cleaning liquid will flow into the steel pipe along the cleaning pipe 62 and cooperate with the cleaning head 63 to realize the cleaning of the inner wall of the steel pipe, and the combination of cleaning and flushing can ensure the cleaning effect of the inner wall of the steel pipe and improve the cleanliness of the inner wall of the steel pipe. Finally, the sewage will be collected into the sewage pool 65, realizing the stable recovery of the sewage, and after recovery, an oil-water separation mechanism can be added in the sewage pool 65 to realize the reuse of the cleaning liquid.

[0046] Since both ends of the steel pipe are inserted into the cleaning pipe 62 at the same time, when cleaning the inner wall, one cleaning pipe 62 can be retracted while the other cleaning pipe 62 continues to slide forward when both cleaning pipes 62 travel to the middle position of the steel pipe, so as to ensure the omnibearing cleaning of the inner wall of the steel pipe.

[0047] The specific embodiment is only an interpretation of the utility model, and is not a limitation of the utility model.
