Oil pipeline clamping fixture

Abstract

The invention discloses an oil pipeline clamping fixture comprising a base plate and an adjusting plate. The end of the base plate is hinged to the end of the adjusting plate, each of the base plate and the adjusting plate is provided with a clamping piece, and the clamping pieces are connected with the base plate and the adjusting plate through bolts. The oil pipeline clamping fixture further comprises pressure claws and connecting rods, each pressure claw is hinged to the upper end portion of each clamping piece, each clamping piece is further provided with a hydraulic cylinder, one end of each connecting rod is hinged to the middle of each pressure claw while the other end is hinged to a connecting piece, and a telescopic end of each hydraulic cylinder is connected with the bottom of each connecting piece. For strengthening stability of placement of the bending oil pipe, a bending portion of the bending oil pipe is placed in the clamping piece of the adjusting plate, a straight line portion is placed in the clamping piece of the base plate, the base plate and the adjusting plate form loose-leaf connection, and an included angle between the base plate and the adjusting plate is enable to change along with the winding path of the bending oil pipe, so that the connecting rods enable the pressure claws to be more flexible in opening and closing, and stability affected by vibration of the hydraulic cylinders during opening and closing of the pressure claws is also avoided.

Description

technical field [0001] The invention relates to a clamping device, in particular to an oil pipeline clamping tool. Background technique [0002] Pipeline transportation is not only large in volume, continuous, rapid, economical, safe, reliable, stable, low in investment, small in land occupation, low in cost, and can be automatically controlled. In addition to being widely used in long-distance transportation of oil and natural gas, it can also For the transportation of ore, coal, building materials, chemicals and food, pipeline transportation can save the transfer of water or land transportation, shorten the transportation cycle, reduce transportation costs, and improve transportation efficiency. The current development trend of pipeline transportation is: the caliber of the pipeline is increasing continuously, and the transportation capacity is greatly improved; the transportation distance of the pipeline is increasing rapidly; the transportation materials are gradually ex...

AI Technical Summary

Problems solved by technology

Medium and long-distance oil transportation requires larger diameter pipelines, and the sealing performance of the pipeline must be guaranteed; at present, the transportation of large-diameter oil pipelines, especially the transportation of oil elbows with curved parts, is relatively difficult, and most companies generally use The cables are bundled and fixed for transportation, but when driving in areas with poor road conditions, the oil elbow often shakes, causing certain damage to the pipeline itself, and in severe cases, the cables may break and cause huge losses
