Problems solved by technology

The jib assembly 20 adopts this side-mounted structure. Although it can meet the construction requirements on site and enable the jib of the jib assembly 20 to lift steel pipes with variable amplitude, there are still technical defects, specifically: due to the The frame assembly 20 is hinged on the bracket on the fixed frame, so the 360° rotation operation cannot be realized during the steel pipe lifting process, which reduces the working efficiency of the steel pipe transportation, hoisting, ditching and other processes
[0003] Although the excavator in the construction site has a slewing function, according to the construction specifications of the excavator, the excavator cannot be directly used to lift steel pipes (mainly because the strength of the excavator boom and the luffing method are not suitable for lifting steel pipes). It is prone to accidents, therefore, the use of excavators to hoist steel pipes is prohibited in the construction specifications of excavators
Therefore, although there are many equipments on the construction site, there is a problem that the utilization rate is not high.

Abstract

The invention discloses a pipe lifting device. The pipe lifting device comprises an excavator chassis, a lifting arm frame and a platform frame, wherein a platform is arranged on the excavator chassis, and is provided with a mounting groove; front mounting holes are oppositely formed in the front ends of two opposite side walls of the mounting groove, and back mounting holes are oppositely formed in the back ends of the two opposite side walls of the mounting groove; the lifting arm frame is detachably connected to the platform through the front mounting holes, and is hinged with a lifting arm; a pipe lifting module is arranged at the top end of the lifting arm; the platform frame is detachably connected to the platform through the back mounting holes, and is provided with a luffing mechanism for driving the lifting arm to perform luffing; and the platform frame is connected with the lifting arm frame. The lifting arm frame and the platform frame use existing mounting holes in the platform for forming stable triangular connection with the platform, so that the overall structure is more stable in operation, can rotate with loads by 360 degrees, realizes multiple purposes on one machine, increases the equipment utilization rate, and improves the pipe lifting efficiency.

Description

technical field [0001] The invention belongs to the technical field of oil and natural gas pipeline hoisting machinery, in particular to a pipe hanging device. Background technique [0002] In the construction of oil and gas pipelines, the transportation, hoisting and ditching of steel pipes are mainly completed by pipelayers. Pipelayers are important construction equipment in oil and gas pipeline construction, such as figure 1 As shown, the pipelayer is mainly composed of a chassis 10, a jib assembly 20, a lifting pulley block 30, a luffing pulley block 40, a hydraulic system 50, a counterweight mechanism 60, a lifting and luffing winch 70, and a hook, among which The two sides of the chassis 10 are respectively provided with a crawler belt, and a bracket extending outward is arranged on the fixed bracket for installing the crawler belt. A counterweight mechanism is required. The jib assembly 20 adopts this side-mounted structure. Although it can meet the construction req...
