Hoisting device for internal quality detection of high pressure tank body for wheel rolling

Abstract

The invention discloses a hoisting device for internal quality detection of a high pressure tank body for wheel rolling. The hoisting device comprises a triangular supporting device and an up-down hoisting device; the triangular supporting device comprises main supporting rods, connection supporting pieces and a bearing plate; the up-down hoisting device comprises a balance rod, a rope and a lifting device; the three main supporting rods are obliquely arranged with the top ends getting close to one another and the bottom ends getting away from one another, and endpoints of the top ends and thebottom ends of the main supporting rods form two triangular shapes parallel to the horizontal plane; the bearing plate is in a triangular shape, the center of the bearing plate is provided with a through hole, and three vertexes are fixed to the top ends of the main supporting rods correspondingly; the multiple connection supporting pieces are welded between the top ends and the bottom ends of the three main supporting rods; the balance rod is arranged at the through hole of the upper plate surface of the bearing plate; and the rope is tied to the middle of the balance rod, and the lower endof the rope penetrates through the through hole to hang the lifting device. The hoisting device is novel and reasonable in structural design, quick in manufacturing, convenient to operate, low in maintenance cost, capable of achieving quick detection of the interior of the high pressure tank body and flaw detection of various welded joints, high in speed and good in effect.

Description

technical field [0001] The invention belongs to the technical field of lifting and relates to a lifting device for detecting the internal quality of a rolling wheel high-pressure tank body. Background technique [0002] Masteel Wheel Co., Ltd. is an important train wheel production base in my country. It is the largest wheel manufacturer in Asia and the only domestic company capable of producing passenger car wheels with speeds above 120Km / h. The research and development of heavy-duty wheels has reached the international advanced level. The company currently has two wheel production lines with an annual production capacity of 800,000 pieces. Its key department is the high-pressure pump room. Eight high-pressure water and air tanks are specially used for the second-line rolling system of wheels. The pressure of water and air medium is 40 MPa. Two rows of vertical placement, of which the height of a single tank is 9 meters and the weight is 16 tons. A special conjoined inspect...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of slow speed, low efficiency and inability to complete the flaw detection of the current high-pressure tank internal body and various welding seams in the background technology, and to formulate a rolling wheel high-pressure tank internal quality inspection method. The lifting device for inspection is implemented and verified through the process. The simple lifting device and method designed by the present invention can not only quickly complete the flaw detection inspection of the interior of the high-pressure tank and various welds, but also reduce the labor intensity of workers and improve Labor efficiency, cost reduction, the device basically does not require large investment, occupies a small space, is convenient to use and maintain, and will not cause deformation of structural parts caused by various factors during hoisting, which will affect the safety of testing personnel and the quality and progress of acceptance , providing a guarantee for rational production
