Abstract
The invention relates to a separation type elastic temperature sensor which comprises a temperature sensor probe and a mounting structure. The mounting structure comprises a hollow protecting tube, a rear limit tube and a telescopic spring. The rear limit tube, the telescopic spring and the temperature sensor probe are mounted in the hollow protecting tube. The outer limit parts of the rear limit tube and the temperature sensor probe are respectively in contact with the upper limit part and the built-in tube in the hollow protecting tube. After assembling of the sensor, the spring is in a slight compression state. During mounting of the sensor, the probe compresses the spring and is mounted at the bottom of a temperature measuring hole in an abutted manner, and the probe end of the hollow protecting tube is screwed into the mounting hole in the lateral side of a motor end cover. During online replacement of the sensor, the long hollow stainless steel protecting tube needs not to be drawn out, the probe and the protecting and mounting parts of the probe are mounted in, and replacement can be performed directly without motor shutdown. By the protecting structures at the probe and the connecting parts of the sensor, the sensor is dustproof, waterproof and high in protecting level.
Description
Technical field
The present invention relates to a kind of temperature sensor, the sensor of the monitoring motor bearings temperature of particularly installing near traction electric machine head bearing.
Background technology
On current simple system type motor train unit traction electric machine, all require running in bearings temperature sensor, bearing temperature sensor used in the prior art, mostly adopt near electric motor end cap (or bearing cap), a kind of more easy short probe plug-type temperature sensor is installed.
Existing temperature sensor mounting means only for the motor of small volume, or need to be installed near the bearing of motor end face, more applicable to frame suspension type motor; Cannot meet the installation requirements of part motor train unit body suspension type pulling motor bearing temperature sensor.As everyone knows, the motor operating condition of installing under car body is more severe, the traction electric machine of part motor train unit vehicle is subject to the impact of its hang, bearing temperature sensor can only pack into from end cap side, if temperature sensor probe is longer, the installing space needing is large, and the limited space that car body is installed, and just cannot meet the operational requirements of online replacing.After breaking down, plug-type temperature sensor cannot be changed, and the car that motor need to be fallen is changed temperature sensor, and the structure of this temperature sensor and mounting means have increased maintenance of motor and maintenance cost greatly, and bring sizable difficulty to user.
Summary of the invention
The technical problem to be solved in the present invention is to provide is convenient to install and the online flexible temperature sensor of separate type band of changing.
In order to solve above technical matters, the technical solution used in the present invention is: a kind of separate type elastic temperature sensor, and it comprises temperature sensor probe and mounting structure, mounting structure comprises hollow protection tube, rear position-limiting tube and coil tension spring;
Described hollow protection tube, its afterbody is provided with to install tightens seat with outer-hexagonal head, and outer-hexagonal head is tightened an arranged outside the fastening nut installation position with exterior tube screw thread; In hollow protection tube, be provided with for the built-in pipe of the lower limit of popping one's head in and with the supporting upper limit portion of rear position-limiting tube; The sound end arranged outside of hollow protection tube has the external thread that use is installed;
Position-limiting tube after coil tension spring one end connects, the other end connects temperature sensor probe; After assembling, rear position-limiting tube, coil tension spring and temperature sensor probe pack in hollow protection tube, and the outside limiting section of rear position-limiting tube and temperature sensor probe contacts with built-in pipe with the upper limit portion in hollow protection tube respectively.
During assembling, by having after the cable of certain cable protection and built-in temperature sensor welding embedding, penetrate successively rear position-limiting tube, coil tension spring, penetrate with the temperature sensor probe of limiting section and complete embedding.The part that temperature sensor assembling finally packs hollow protection tube into is divided into three joints: rear position-limiting tube, coil tension spring, with spacing probe, and while installing online, flexible and insert section by section, greatly saved installing space, little spatial operation is become a reality.After assembling; the limiting section of rear position-limiting tube is slightly longer than to the limiting section size of temperature sensor probe the spacing spacing in two ends that hollow protection tube arranges, to guarantee that after assembling, spring is in mild compression state; while installing and using, thereby the Compress Spring that can make to pop one's head in holds out against and is installed on thermometer hole bottom.Hollow protection tube sound end is screwed in the mounting hole of electric motor end cap side.
At the outer-hexagonal head of hollow protection tube, tighten on the outside fastening nut installation position of seat the fastening nut that is built-in with sealing joint strip is installed.Fastening nut inside arranges sealing joint strip, at itself and hollow protection tube, installs while tightening, and can play the effect of sealing protection, reaches the object of high protection;
The present invention also comprises electric cable protection hose, and the link of electric cable protection hose is provided with stainless joint, and stainless joint is tightened seat by fastening nut and the outer-hexagonal head on hollow protection tube and is connected.Temperature sensor cable penetrates cable protection pipe access signal connector and is connected with signals of vehicles; It is fastening that stainless joint and fastening nut and electric cable protection hose adopt crimping mode to install, and guarantees degree of protection; Fastening nut, in tightening installation process, can rotate relatively with electric cable protection hose, prevents cable protection pipe torsional deformation.
Described electric cable protection hose inside is provided with metallic shield web frame.
The outer-hexagonal head of fastening nut and hollow protection tube afterbody is tightened on the exterior tube screw thread between seat cover locking cramp and rubber seal, locking cramp have have can bending outer rim.Before fastening nut being arranged on to the screw thread of hollow stainless steel protection pipe afterbody, locking cramp and rubber seal are enclosed within on the screw thread of hollow protection tube afterbody, after tightening, rubber seal can reach the object of high protection, and four jiaos of bending lockings of locking cramp can be reached to locking object;
Probe provided by the invention adopts split type installation, optimized the assembling manufacturing method of temperature sensor, solved it and cannot change online and overhaul difficult problem when breaking down, during online replacing, need not extract the long hollow stainless steel protection pipe in space out, directly probe and protection thereof and installing component are packed into, do not need the motor car that falls directly to change; By position-limiting tube and coil tension spring being set near probe, can make the probe of temperature sensor hold out against and be arranged on thermometer hole bottom, reach the object of effective thermometric; By at temperature sensor probe position and the safeguard structure that arranges of each connecting portion; make temperature sensor possess function dustproof, waterproof; the degree of protection of each connecting portion is higher; for the above degree of protection of IP67, temperature sensor extension line is placed in sky protection tube and electric cable protection hose and can effectively protects.
Temperature sensor provided by the invention not only can effectively protect but also can facilitate replacing online, and parts can flexible assembling.Than general plug-in bearing temperature sensor, be more suitable for severe operating mode, antivibration effect is remarkable, and its bearing temperature sensor probe more approaches bearing, can more accurately detect bearing temperature.
