Abstract

The utility model belongs to the technical field of the deep well heat damage prevention and control in the mining engineering, which particularly relates to an expansion joint device for a deep well ice-delivering pipeline. The expansion joint device for the deep well ice-delivering pipeline consists of an expansion sleeve cylinder system and hydraulic oil cylinders, wherein the expansion sleeve cylinder system consists of an inner cylinder and an outer cylinder sleeve; the inner cylinder and the outer cylinder sleeve are oppositely arranged; the external diameter of the inner cylinder is equal to the internal diameter of the outer cylinder sleeve; the outer wall of the inner cylinder is tightly fit with the inner wall of the outer cylinder sleeve; the tip of the inner cylinder and the tip of the outer cylinder sleeve are respectively provided with an expansion connecting flange plate; two hydraulic oil cylinders are symmetrically assembled between the two expansion connecting flange plates; and the expansion movement of the expansion connecting flange plates is controlled by the hydraulic oil cylinders. When the expansion joint device for the deep well ice-delivering pipeline is adopted, the ice-delivering pipeline can be quickly and conveniently connected again without pushing and pulling the pipeline with external force, and the butt joint of the pipeline can be better realized by the expansion function of the expansion joint.

Description

A kind of deep-well ice transport pipe expansion joint device

Technical field

The utility model belongs to mining engineering deep-well heat evil Prevention Technique field, is specifically related to a kind of deep-well ice transport pipe expansion joint device.

Background technique

Along with the increasing of China's energy-consuming, the deep mining stage is stepped in coal production gradually, and along with the increasing of mining depth, geothermal phenomenon is further serious.A kind of ice slurry falling temperature technique is arranged in administering underground thermal pollution, namely starch as refrigeration working fluid with high density refrigerating medium ice, adopt pipeline to carry the ice slurry to the terminal of lowering the temperature.At present when the first installation of ice slurry pipeline, adopt successively one saved the mounting type that connects a joint more, each section pipeline is coupled together, but stifled or carry out pipeline when changing when ice occurs, almost all exist upgrade the replace tubes road or safeguard after the problem that do not get on of former pipeline installation.The reason that the generation pipeline does not connect is a lot, as: down-hole STRESS VARIATION can make that pipeline produces that stress is concentrated, the ice slurry in course of conveying to active force, subsurface environment and the ice slurry of pipeline to the shrinkage effect of pipeline etc., when will be wherein after a pipe joint road unloads, stress will redistribute, and reinstall that the non-length of pipeline will inevitably to occur be short situation again.

Generally adopt at the construction field (site) at present the powerful method that pulls pipeline, this method usually can cause the accident that sealing joint is tight or ice transport pipe is broken.

Summary of the invention

Pipeline docking hard problem appears in safeguarding installation for present deep-well ice transport pipe, the utility model provides a kind of deep-well ice transport pipe expansion joint device, adopt hydraulics to advance telescopic pipe, can make things convenient for, effectively solve traditional stock line and reconnect hard problem.

Deep-well ice transport pipe expansion joint device of the present utility model is comprised of telescopic cover cylinder system and hydraulic jack, described telescopic cover cylinder system is comprised of inner casing and outer cylinder sheath, wherein inner casing and outer cylinder sheath are oppositely arranged, the external diameter of inner casing equals the internal diameter of outer cylinder sheath, the outer wall of inner casing and the inwall of outer cylinder sheath fit tightly, respectively be provided with a flexible mounting flange in the termination of inner casing and outer cylinder sheath, symmetry is equipped with two hydraulic jacks between two flange plate, and controls the telescopic moving of flexible mounting flange by hydraulic jack.

Compared with prior art, characteristics and the beneficial effect of deep-well ice transport pipe expansion joint device of the present utility model are:

(1) adopt deep-well ice transport pipe piecing devices of the present utility model, quick and easy when ice transport pipe connects again, needn't adopt external force push-and-pull pipeline, can adopt the Telescopic of expansion joint to realize better the docking of pipeline.

(2) adopt deep-well ice transport pipe piecing devices of the present utility model; effectively prolonged the working life of down-hole ice transport pipe; the ice transport pipe of down-hole is in cloth postpone; be subjected to mining influence usually can be subject to the effect of crustal stress; so that producing stress, concentrates each pipeline enclosure; expansion joint can effectively be extenuated pipe stress and be concentrated, and weakens the concentrated stress of pipeline enclosure.

(3) owing to adopting expansion joint not need external force to pull pipeline, so 1-2 people can realize that just pipeline changes and maintenance task, save time, laborsaving.

Fig. 3 is ice transport pipe and the figure that connects of expansion joint device;

Wherein, 1: inner casing; 2: outer cylinder sheath; 3: flexible mounting flange; 4: hydraulic jack; 5: bolt; 6: the flexible glue packing ring; 7: ice transport pipe; 8: the pipe head flange plate.

Embodiment

Below in conjunction with Figure of description and specific embodiment deep-well ice transport pipe expansion joint device of the present utility model is further specified.

Embodiment

Deep-well ice transport pipe expansion joint device of the present utility model is comprised of telescopic cover cylinder system and hydraulic jack 4, wherein said telescopic cover cylinder system is comprised of inner casing 1 and outer cylinder sheath 2, inner casing 1 wherein is oppositely arranged with outer cylinder sheath 2, the external diameter of inner casing 1 equals the internal diameter of outer cylinder sheath 2, the inwall of the outer wall of inner casing 1 and outer cylinder sheath 2 fits tightly, respectively be provided with a flexible mounting flange 3 in the termination of inner casing 1 and outer cylinder sheath 2, symmetry is equipped with two hydraulic jacks 4 between two flexible mounting flanges 3, and controls the telescopic moving of flexible mounting flange 3 by hydraulic jack 4.

Link to each other by pipe head flange plate 8 between the deep-well ice transport pipe originally, when using deep-well ice transport pipe expansion joint device of the present utility model, adding on the pipe head flange plate 8 of a certain section ice transport pipe 7 therein has the flexible glue of through hole packing ring 6 in the circle, and link by bolt 5 and flexible mounting flange 3, so just an end of expansion joint device and ice transport pipe 7 are connect and be integrated, and then adjustment hydraulic jack 4, make another flexible mounting flange 3 of expansion joint device move to pipe head flange plate 8 places of another section ice transport pipe 7, between two flange plate, add equally flexible glue packing ring 6, and link by bolt 5, so just two sections ice transport pipes are bonded together by expansion joint device.

When needs place under repair to ice transport pipe, can open bolt 5 with its dismounting in expansion joint place, the installation after the dismounting can be according to the distortion size, come the distance between the pipeline is adjusted by the hydraulic jack 4 in the expansion joint device, needn't pull ice transport pipe with external force.
