Description

Technical Field

[0001] The invention belongs to the technical field of pipe row transportation, in particular to a pipe row transportation device. Background Art

[0002] The tube roller is an important equipment transportation unit of the finishing production line, and the three trolleys of each saw are installed above the roller to determine the size of the steel tube. The hole type produced by the 460 unit is 294-488. When the specification is greater than 406, only two steel tubes can be arranged on the roller, which is easy to deviate during the roller transportation process, causing the tube end to hit the trolley installed above the roller, causing damage to the trolley parts and seriously affecting the quality of the product.

[0003] The possible reasons for the deviation are: the row of steel pipes is prone to deviation during transportation due to different amounts of roller surface wear after a period of use; at the same time, the radius of the large-hole pipe exceeds the roller edge and cannot be retracted by the roller, causing the pipe end to collide with the trolley installed above the roller, causing damage to the trolley components and seriously affecting the quality of the product. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects existing in the prior art and provide a pipe row transportation device that can solve the above-mentioned problems existing in the prior art.

[0005] A pipe row transport device comprises a supporting steel frame, rollers and a gathering structure, wherein a plurality of rollers are arranged in parallel and rotatably mounted on the supporting steel frame; the gathering structure is installed between the rollers and is used to gather the transport steel pipes on the rollers towards opposite directions.

[0006] Furthermore, the folding structure includes a folding unit, and two folding units are symmetrically arranged and installed between the rollers or on one side of the rollers.

[0007] Furthermore, the folding unit includes an auxiliary roller, a mounting seat, an inner hinge, an outer hinge, an inner support seat, an outer support seat and a lifting assembly, the auxiliary roller is rotatably installed in the mounting seat, one end of the mounting seat is hinged to the inner support seat through an inner hinge, the other end of the mounting seat is hinged to one end of the lifting assembly through an outer hinge, and the other end of the lifting assembly is hinged to the outer support seat; and the inner support seat is located above the side of the outer support seat.

[0008] Furthermore, the auxiliary roller shaft is a tapered roller.

[0009] Furthermore, the height of the top of the roller from the ground is greater than the height of the auxiliary roller from the ground.

[0010] Furthermore, the lifting assembly adopts a cylinder, and the drive shaft of the cylinder is hinged to the external hinge.

[0011] Further, the support steel frame includes U-shaped steel and a base, and several U-shaped steels are symmetrically installed on the base in pairs.

[0012] Further, the driving shaft of the cylinder penetrates through the base and is hinged to the outer hinge member.

[0013] Further, the folding unit further includes a bottom mounting seat, and the outer support seat is mounted on the bottom mounting seat.

[0014] The advantages and beneficial effects of the present invention are as follows:

[0015] (1) The steel pipes are transported through the roller shafts, and the folding structure is installed between the roller shafts or on one side of the roller shafts. The steel pipes can be folded inward by the folding structure, avoiding the deviation of the steel pipes to both sides of the roller shafts during the transportation by the roller shafts; through this folding structure, the quality problems of pipe end bruises and equipment damage can be solved.

[0016] (2) When the steel pipes need to be folded inward, the lifting assembly pushes one end of the mounting seat upward through the outer hinge member, and the other end of the mounting seat rotates through the inner hinge member, so that the auxiliary roller shaft mounted on the mounting seat is in an inclined state to push the steel pipes inward to fold them; in addition, the auxiliary roller shaft is rotatably mounted in the mounting seat to avoid affecting the surface quality of the steel pipes.

[0017] (3) By adding one or more groups of folding structures between the steel pipe transportation roller paths, the offset steel pipes are folded and centered after contacting the auxiliary roller shafts. At the same time, the auxiliary roller shafts are rotatably mounted in the mounting seats through bearing seats and will not affect the surface quality of the steel pipes.
