Problems solved by technology

[0003] The traditional steel pipe forced feeding machine generally transmits power through gears and universal joints. The clamping of the driving wheel and the driven wheel is driven by an air cylinder or hydraulic cylinder. It will vary with the diameter of the pipe, and the impact of the pipe's own disturbance on the clamping system during the transportation process will affect the service life
These shortcomings limit the application of traditional steel pipe strong conveying machines in systems that require higher conveying accuracy, more stable and reliable

Abstract

The invention discloses a strong conveying machine for steel pipes. The strong conveying machine comprises an engine base, a driving wheel, a driven wheel, a transmission device and a clamping mechanism, wherein the transmission device drives the driving wheel mounted on the engine to rotate through a transmission part; the clamping mechanism is arranged in a lower cavity of the engine base, acts on a lifting screw rod and a lifting block to limit the driven wheel and produces pressing force on the steel pipes; meanwhile, the driven wheel is glidingly mounted on a rectangular guide rail and produces support, and the rectangular guide rail is fixedly mounted on the engine base. Each steel pipe is clamped tightly by the driving wheel and the driven wheel, the radial positioning precision is + / - 1 mm, the machine is applicable to steel pipes with different diameters ranging from phi 45 to phi 80, and the steel pipes are driven to be fed continuously in the axial direction through friction force produced on the surfaces of the steel pipes by means of rotation of the driving wheel in fixed position. Compared with the traditional equipment, the radial positioning precision is high, the structure is simple and compact, conveying stability is high, the transmission device and the clamping mechanism are stable and reliable, and the conveying machine is conveniently integrated to axial continuous steel pipe conveying in an automatic steel pipe processing system.

Description

technical field [0001] The invention relates to the technical field of conveying equipment, in particular to a steel pipe forced conveying machine. Background technique [0002] The steel pipe force feeder is the key equipment for long-distance axial transportation of seamless steel pipes, especially suitable for continuous feeding of super-long pipe fittings. The working principle of the steel pipe forced feeding machine is: the driving wheel of the strong feeding machine is driven by the motor to rotate, and the driven wheel equipped with the pressing device presses the steel pipe on the driving wheel to ensure that the steel pipe is in close contact with the driving wheel, and the distance between the driving wheel rotation and the steel pipe Friction provides the power for the axial movement of the steel pipe. [0003] The traditional steel pipe forced feeding machine generally transmits power through gears and universal joints. The clamping of the driving wheel and the...
