Method for disassembling sleeved pipe modules based on hydraulic disassembly tool vehicle

Abstract

The invention relates to a method for disassembling sleeved pipe modules based on a hydraulic disassembly tool vehicle. During operating, firstly, a driving oil cylinder and a support oil cylinder respectively drive a first connecting base and a second connecting base to ascend to enable a connecting rod to align to center channels of the sleeved pipe modules; then, a driving device drives the connecting rod to move forwards to enable a chuck to extend in from the back ends of the center channels and to extend out from the front ends of the center channels; the driving oil cylinder and the support oil cylinders respectively drive the first connecting base and the second connecting base to ascend to align clamping surfaces to the upper parts of front end orifices of inner connecting pipes;the driving device drives the connecting rod to move back, and the clamping surfaces are tightly buckled with the upper parts of the orifices of the inner connecting pipes; a forklift forwards moves to support a bearing frame at the back ends of outer sleeves; finally, the driving device drives the connecting rod to backwards pull; and the chuck backwards pushes the inner connecting pipes to separate the inner connecting pipes from the outer sleeves, so that the sleeved pipe modules can be conveniently disassembled, both time and manpower are saved, and the human resources and the cost are saved.

Description

technical field [0001] The invention relates to a method for dismantling a socket pipe assembly based on a hydraulic dismantling tooling vehicle, in particular to a method for dismantling an air supply duct of an ironmaking blast furnace. Background technique [0002] The air supply pipes of ironmaking blast furnaces are generally connected by sockets, and the inner connecting pipe at the forefront is the nozzle of the air supply pipe. Due to the need to continuously discharge materials into the blast furnace through the nozzles during the production process, coupled with high temperature and other factors , The nozzle is easily damaged, and the damaged nozzle will be perforated, which will cause the cooling water inside the air supply pipe to leak into the furnace, affecting normal production. Therefore, the nozzle of the leaking air supply duct must be replaced in time. The rear end of the inner connecting pipe at the front end is sleeved with an outer sleeve. In order to...

Problems solved by technology

At present, when replacing the inner connecting pipe at the front end of the air supply pipe, it is necessary to manually pull out the tuyere, using a special sliding hammer for drawing, first hooking the front end of the inner connecting pipe, and then 12-16 people stand on the outer pipe separately The two sides on the outside pull the floating hammer back and forth to make the oil hammer reciprocate back and forth, and use the impact generated when the floating hammer moves backward to pull the inner connecting pipe backward to separate the inner connecting pipe from the outer casing. This method is time-consuming and laborious. consumption of human resources
