Hoisting and conveying integrated equipment for petroleum pipeline laying pipe fitting

Abstract

The invention belongs to the technical field of petroleum pipeline hoisting and conveying, and particularly relates to hoisting and conveying integrated equipment for a petroleum pipeline laying pipe fitting. The hoisting and conveying integrated equipment comprises a vehicle body, wherein crawler walking mechanisms are arranged on the two sides of the vehicle body, a driving module is slidably arranged on the vehicle body, and a strip-shaped plate is arranged on the driving module; a square groove is formed in the strip-shaped plate, and a lifting block is vertically arranged on the strip-shaped plate in a sliding mode through the square groove; a hoisting mechanism is arranged on the strip-shaped plate, a hoisting belt is arranged on the lifting block, and a plurality of first through holes are formed in the hoisting belt in the horizontal direction; a plurality of positioning rods are arranged on the side wall of the lifting block, and the ends of the positioning rods are fixedly connected through a connecting plate; and a positioning screw rod is arranged on the side wall of the lifting block and penetrates through the connecting plate in a screw-thread fit manner. The falling speed of the pipe fitting is reduced, and strong collision between the pipe fitting and a support in a foundation pit is avoided. In addition, the hoisting belt is completely attached to the surface of the pipe fitting, and the stability of the pipe fitting in the hoisting process is improved.

Description

technical field [0001] The invention belongs to the technical field of oil pipeline hoisting and transportation, and in particular relates to an integrated equipment for hoisting and transportation of pipe fittings for laying oil pipelines. Background technique [0002] Petroleum pipelines are composed of pipe fittings and their accessories, and are equipped with corresponding oil pump units according to the needs of the process, designed and installed as a complete pipeline system to complete the tasks of oil unloading and transportation; oil pipelines are usually laid below the ground In the foundation pit, the bracket is first fixed in the foundation pit during installation, and then the pipe fittings are lifted by the hoisting equipment and transported to the bracket, and the adjacent pipe fittings are connected by flanges. [0003] At present, in the process of laying oil pipelines, the pipe fittings are usually hoisted and transported directly by the crane. The crane h...

Problems solved by technology

[0003] At present, in the process of laying oil pipelines, the pipe fittings are usually hoisted and transported directly by the crane. The crane has the following problems in the process of hoisting and conveying: (1) When the pipe fittings are placed on the bracket, the pipe fittings fall faster , it is easy to have a strong collision with the bracket, which will cause the bracket to sink and affect the installation accuracy of the pipe fittings; The belt itself is prone to wrinkles, and it is difficult to completely fit the surface of the pipe fittings, which affects the stability of the pipe fittings during hoisting
