Technical Field

[0001] This utility model relates to the technical field of steel pipe conveying equipment, specifically to an automatic alignment device for steel pipe screw drive. Background Technology

[0002] Chinese Patent Publication No. CN204508174U discloses a spiral seam ultra-long welded steel pipe conveying assembly. This assembly includes side guide rollers and conveying rollers. The position of the conveying rollers on the conveying roller frame is adjusted by a conveying roller adjusting screw, and the position of the side guide rollers on the inclined surface of the wedge block is adjusted by a side guide roller adjusting screw. Simultaneously, the conveying roller frame and the conveying rollers are connected by screws, and the angle of the conveying rollers can be adjusted by adjusting the screws. The wedge block and the side guide rollers are connected by screws, and the angle of the side guide rollers can be adjusted by adjusting the screws. This allows for the adjustment of the position and angle of the side guide rollers and conveying rollers, thereby achieving spiral conveying of the steel pipe. However, this adjustment method requires manual adjustment of each component, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an automatic alignment device for steel pipe screw transmission, which solves the problem that the adjustment of existing screw conveyor equipment is time-consuming and labor-intensive.

[0011] An electric push rod is mounted on the mounting plate, and one end of the electric push rod is connected to either the first or the second rotating wheel seat.

[0012] Both the motor and the electric push rod are equipped with encoders.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the automatic alignment device for steel pipe screw drive includes a V-shaped support 1, on which a driving wheel 2 and a driven wheel 3 are mounted, and further includes:

[0028] Mounting plates 4 are symmetrically arranged on both sides of bracket 1;

[0029] The first rotating wheel seat 5 is rotatably mounted on the mounting plate 4 and has a drive wheel 2 installed on it;

[0030] The second rotating wheel seat 6 is rotatably mounted on the mounting plate 4 and has a driven wheel 3 installed on it;

[0031] Linkage assembly 7 is used to connect the first rotating wheel seat 5 and the second rotating wheel seat 6;

[0032] A horizontal reciprocating mechanism 8 is mounted on the bracket 1 and cooperates with the mounting plate 4 to drive the mounting plate 4 to move relative to each other and to each other. The horizontal reciprocating mechanism 8 is equipped with a motor 9.

[0033] An electric push rod 10 is mounted on the mounting plate 4, and one end of the electric push rod 10 is connected to either the first rotating wheel seat 5 or the second rotating wheel seat 6.

[0034] Both the motor 9 and the electric push rod 10 are equipped with encoders.

[0035] The mounting plates 4 are moved closer and further apart by the motor 9, thereby adjusting the distance between the driving wheel 2 and the driven wheel 3. The angles of the driving wheel 2 and the driven wheel 3 on the mounting plate 4 can be adjusted simultaneously by the extension and retraction of the connecting rod assembly 7 and the electric push rod 10. The encoder is connected to the control center. After the control center transmits the specifications of the steel pipe, the control center sends a signal to the encoder. The encoder controls the number of rotations of the motors in the motor 9 and the electric push rod 10 to complete the automatic line adjustment. This not only saves time and effort but also has high efficiency.

[0036] In the embodiments, such as Figure 4 As shown, the bottom surfaces of both the first rotating wheel seat 5 and the second rotating wheel seat 6 are provided with arc-shaped through grooves 11 for mating with the mounting plate 4. Bolts pass through the arc-shaped through grooves 11 and connect to the mounting plate 4. After adjustment, the first rotating wheel seat 5 and the second rotating wheel seat 6 are locked with bolts to prevent deviation during steel pipe conveying, which would affect the conveying accuracy.

[0037] In the embodiments, such as Figure 1As shown, a guide rail assembly 12 is provided between the bracket 1 and the mounting plate 4. This ensures the straightness of the movement of the mounting plate 4, thereby guaranteeing the accuracy of the screw conveyor.

[0038] In the embodiments, such as Figure 1 , Figure 3 As shown, the horizontal reciprocating mechanism 8 includes a first lead screw 81 and a second lead screw 82 with opposite thread directions, and a coupling 83 connects the first lead screw 81 and the second lead screw 82. Only one motor 9 is needed to control the relative and opposing movements of the two mounting plates 4, resulting in a simple structure, low production cost, and high precision.

[0039] In the embodiments, such as Figure 1 , Figure 2 As shown, the connecting rod assembly 7 includes a main rod 71 and adjusting rods 72 located at both ends of the main rod 71. The adjusting rods 72 are movable relative to the main rod 71. Both the first rotating wheel seat 5 and the second rotating wheel seat 6 are equipped with angle scales 13. The adjusting rods 72 and the main rod 71 are threaded together. By fine-tuning the adjusting rods 72 and observing the angle scales 13, it is ensured that the first rotating wheel seat 5 and the second rotating wheel seat 6 on the mounting plate 4 remain parallel, thereby ensuring the accuracy of the steel pipe screw drive.

[0040] In the embodiments, such as Figure 2 As shown, there are two sets of horizontal reciprocating mechanisms 8. A reducer 14 is provided between the horizontal reciprocating mechanism 8 and the motor 9. The motor 9 is a dual-shaft motor. The two sets of horizontal reciprocating mechanisms 8 are respectively set at both ends of the mounting plate 4 to ensure the smooth movement of the mounting plate 4. Both sets of horizontal reciprocating mechanisms 8 can be controlled by one motor 9, which is low cost.

[0041] In the embodiments, such as Figure 1 As shown, the driving wheel 2 on one of the mounting plates 4 and the driven wheel 3 on the other mounting plate 4 are arranged in a left-right correspondence. Driving wheels 2 are arranged on both sides of the steel pipe to ensure that the steel pipe can be smoothly conveyed by a spiral.

[0042] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
