Description
Technical field
The utility model relates to coal mining equipment sensing device, is specially the external stroke sensing device of a kind of hydraulic support.
Background technology
At present, stroke sensor uses more extensive in electro-hydraulic control hydraulic support, stroke sensor is generally adopted to be built in advancing jack in electro-hydraulic control hydraulic support, stroke sensor is utilized to measure the numerical value of advancing jack stroke, feed back to electrohydraulic control system, controlled by electrohydraulic control system and feed back the cut step pitch of coalcutter.
The problems such as such stroke sensor is generally built in the piston rod of advancing jack, and the processing technology that there are the corresponding parts of lifting jack in actual production process is loaded down with trivial details, and processing capacity is large, and stroke sensor installation procedure is complicated; In the use procedure of down-hole, as stroke sensor be damaged or without problems such as numeric feedback time, the problems such as dismounting difficulty, maintenance difficulty be large are existed to the inspection and maintenance of stroke sensor.
Summary of the invention
The utility model is placed in device memory in the large and problem of inefficiency of installation, large, the maintenance difficulty of dismounting labour intensity to solve existing stroke sensor, provides the external stroke sensing device of a kind of hydraulic support.
The utility model adopts following technical scheme to realize: the external stroke sensing device of hydraulic support, comprise outer tube, the ladder sleeve pipe that concentric and base diameter is greater than upper diameter is provided with in outer tube, the bottom of outer tube is provided with stroke sensor, distribution is up and down provided with and the sensor magnet ring be enclosed within stroke sensor and magnet ring plug below the cascaded surface of ladder sleeve pipe, the upper end of ladder sleeve pipe is provided with the upper connection otic placode stretching out outer tube, the upper end of outer tube is provided with upper plug head, outer tube lower end is provided with lower connection otic placode, cable drum knot chamber is provided with in outer tube below stroke sensor, outer tube sidewall is provided with the auxiliary sleeve pipe tied chamber with its cable drum and be communicated with, the top of auxiliary sleeve pipe is provided with cable splice socket.
During operation, upper and lower connection otic placode is fixed on the appropriate location of column or lifting jack by bearing pin or bolt, upper connection otic placode is pulled by column or the flexible of lifting jack, and then drive ladder sleeve pipe, sensor magnet ring slides in the induction range of stroke sensor, to record the numerical value of column or lifting jack actuating length, feed back to electrohydraulic control system and carry out further treatment and analysis, overcome existing stroke sensor and be placed in device memory in the large and problem of inefficiency of installation, large, the maintenance difficulty of dismounting labour intensity.
The utility model reasonable in design is reliable, efficiently solve the problem that lifting jack processing technology is complicated, operation is many, the production cycle is long of built-in stroke sensor, effectively reduce the labour intensity safeguarded and overhaul stroke sensor, expand the range of application of stroke sensor in electrohydraulic control system, there is simple and ingenious structure, difficulty of processing and low cost of manufacture, easy accessibility, the advantage of applied range.
