Technical field
The utility model relates to a kind of pick-up unit of fluid circuit plugging, particularly relate to a kind of pick-up unit of the paste filling pipe plugging for filling mine workplace, belong to paste filling pipe slurry pipeline transport technical field, the length that is applicable to the filling in mine exploitation detects apart from the paste filling pipe plugging.
Background technology
China is the coal production of maximum in the world and the big country of consumption, along with the raising of technology level, in order to liberate " three times ", presses coal, and the filling technique in colliery has obtained great development.But paste body filling is carried nonhomogeneous media, easily plugging, once plugging, whole filling system will cause heavy losses.The plugging detection technique is one of difficult point of paste body filling technology, and the mode of at present main adopts pressure sensor detects, and when certain section line pressure is elevated to set pressure, backfill control system thinks that plugging appears in the pipeline of its back.
Current common pressure transducer; be difficult to adapt to the flow at high speed of slip in pipeline; for example, and sandstone etc. is easy to the build-up of pressure sensor and can't detect pressure (stone just blocks up the detection mouth of detecting element; when pressure increases; can't detect force value; as shut down not in time, pipe explosion accident may appear), the wearing quality of pressure transducer is also had relatively high expectations.So common pressure transducer is not suitable for the paste body filling plugging and detects, and its price is more expensive, has increased the input of filling.
The principle of another kind of pipeline plugging pick-up unit be spring fitting in the device of similar threeway, slip promotion piston overcomes spring force and carrys out detected pressures, utilize the decrement of spring to be directly proportional to the pressure of conveyance conduit, select spring according to the pressure of conveyance conduit, thereby detect lotion slip pipeline pressure.Although this device is simple in structure, each use must be according to the pressure selection spring of pipeline, and after each the use due to the spring performance change, can not reuse, thereby also be difficult to application widely.
Summary of the invention
The purpose of this utility model just is to overcome the prior art above shortcomings, provides a kind of pressure adjustable type paste filling pipe plugging pick-up unit.The utlity model has simple in structure, reliability is high, according to user's demand, multiple pressure pipeline plugging can be set detects, and can repeat practicality, need perforate on pipeline, characteristics that cost is low, be particularly suitable for the detection of paste body filling plugging.
The technical scheme that the utility model provides is: this pressure adjustable type paste filling pipe plugging pick-up unit, include lower cylinder body 1 and upper cylinder body 4, be characterized in lower cylinder body 1 being provided with orienting sleeve 8, orienting sleeve 8 is provided with O-ring seal 6 and guide ring 7, described orienting sleeve 8 matches with piston rod 11, on described piston rod 11, feather key 9 is housed, positive stop 10, detecting element 2 and piston 12, described piston 12 is provided with guide ring 13 and O-ring seal 14, the upper hydraulic fluid port of described upper cylinder body 4 and tensimeter 15, retaining valve 16 is connected with direct-acting overflow valve 17, on described upper cylinder body 4, measuring switch 3 also is housed, the top of upper cylinder body 4 is provided with the upper cylinder cover 5 for sealing, described lower cylinder body 1, upper cylinder body 4 and orienting sleeve 8 are bolted, described upper cylinder body 4 and upper cylinder cover 5 are bolted.
In technique scheme, the effect of O-ring seal 6 is to prevent that slip from entering cylinder interior; Guide ring 7 is directly contact with cylinder body while preventing piston movement and rub and protect piston and cylinder body not damaged with 13 effect; Hydraulic system is the design's key, according to the maximum working pressure (MWP) value of the plugging pressure setting direct-acting overflow valve 17 in conveyance conduit, when straight moving surplus valve 17 reaches the default pressure of opening, opens.Feather key 9 slides in the keyway of orienting sleeve 8, rotates while preventing piston rod movement or is offset; Detecting element 2 moves upward with piston rod 11, while touching measuring switch 3, reports to the police.
Plugging of the present utility model detects principle: same section lotion line pressure equates everywhere, its force value of pressure setting of direct-acting overflow valve 18 pipeline during according to plugging, when the pressure of carrying in normal range, material flows through in managing, piston rod 11 is substantially motionless, when pipeline generation plugging, the transfer pipeline increased pressure, the pressure acted on piston rod increases, the pressure in hydraulic chamber also increases thereupon, when pressure increases to the force value that is greater than direct-acting overflow valve 17 settings, direct-acting overflow valve 17 is opened, hydraulic medium forms path, hydraulic cavities communicates with hydraulic reservoir, hydraulic medium in hydraulic cavities is got back to fuel tank, slip promotes piston rod and moves upward, detecting element 2 moves upward with piston simultaneously, when detecting element 2 touches measuring switch 3, pressure alarm, thereby completing fast the pipeline plugging detects.
In order to realize the repeatedly use of this pick-up unit, allow power source be connected with oil-in, by oil-in, retaining valve injects hydraulic medium in hydraulic cavities, realizes repeatedly using.
Compared with prior art, the beneficial effects of the utility model are: for coal mine paste filling pipeline characteristics, realized that the robotization of paste filling pipe plugging detects.By this pick-up unit is installed between transfer pipeline, when plugging appears in the pipeline of pick-up unit back, slip promotes piston rod and moves upward, force the hydraulic cavity pressure to increase, when line pressure increases to the pressure that is greater than the direct-acting overflow valve setting, direct-acting overflow valve is opened, hydraulic cavities communicates with fuel tank, piston rod moves upward, detecting element also moves upward with piston rod, when detecting element touches detector switch, send the plugging alerting signal, after outside filling controller collects the plugging alerting signal, automatically stop the filling pump work, guarantee the safety of whole pipeline, by plugging detection alarm position, can judge fast the plugging position, thereby quick solution plugging problem.
