Abstract
The invention relates to a hammer crusher for a coal mine well, in particular to a hammer shaft assembly system capable of monitoring the bearing temperature of a crusher. In the prior art, since the running temperature of a bearing in a hammer shaft assembly can not be controlled, the bearing is damaged and cannot be used any longer within a short time because of poor lubrication and the deteriorated running status, resulting in the shutdown of the crusher. The hammer shaft assembly system capable of monitoring the bearing temperature of the crusher is characterized in that bearing blocks at two ends of the system are internally and respectively provided with a stepped long hole with a thread, the left end of a temperature fast-insertion sensor base is connected and fixed with the thread at the inlet of the stepped long hole of each bearing block, a probe is arranged in each stepped long hole, the upper part of an adapter substitute is inserted into a hole at the right end of the temperature fast-insertion sensor base and is fixed by a screw nail, the lower part of the adapter substitute is connected with a fast-insertion cable, the fast-insertion cable is connected with an electric liquid comprehensive monitoring system, and the electric liquid comprehensive monitoring system is fixed at a protective plate at the head of the crusher by a bolt. Therefore, operators can timely monitor the running of the crusher.
Description
Technical field
The present invention relates to a kind of underground mine use hammer crushing machine, specifically a kind of hammer axle assembly system that monitors disintegrating machine bearing temperature.
Background technology
The hammer axle assembly is the core component of hammer mill, is fixed on the hammer mill frame through bearing block, and torque is passed to the hammer axle by motor through transmission device, and hammer axle high speed rotating drives tup and is broken into required lumpiness to the coarse coal impact cutting.In the prior art; The running temperature of hammer axle assembly middle (center) bearing is uncontrollable, and is not in place or damage because of operation conditions worsens when bearing lubrication, causes hammering into shape the unusual or temperature of axle assembly bearing temperature rise and reaches unallowed when high-order; Cause bearing just to be scrapped in the short time, cause the disintegrating machine disorderly closedown.
Summary of the invention
The purpose of this invention is to provide a kind of hammer axle assembly system that monitors disintegrating machine bearing temperature, can reach the duty of automatic monitoring disintegrating machine, improve the reliability of disintegrating machine.
The technical solution adopted for the present invention to solve the technical problems is: plug in sensor, crossover sub, fast plug-in cable, electric liquid comprehensive monitoring system and bolt soon by bearing block, temperature and constitute; In the bearing block at hammer axle assembly two ends, be respectively equipped with threaded ladder slotted hole; Temperature is plugged in sensor soon and is formed (pedestal and probe are structure as a whole) by pedestal and the probe above it; The pedestal left end is fixed together with being threaded of bearing block ladder slotted hole porch; It is inner that probe stretches into the ladder slotted hole, and crossover sub top is inserted in the slotting soon sensor base right-hand member hole of temperature and through screw and fixed, and the crossover sub bottom connects with fast plug-in cable; Fast plug-in cable also connects electric liquid comprehensive monitoring system, and electric liquid comprehensive monitoring system is through being bolted to disintegrating machine head backplate place.
The invention has the beneficial effects as follows: the bearing temperature in the hammer axle assembly running can be monitored in real time, and electric liquid comprehensive monitoring system is analyzed, handles, calculated the bearing temperature signal that collects, thereby grasps the bearing operation situation of hammer axle assembly at any time; When bearing temperature is unusual; Can send the control instruction that continues operation, alarm indication, disorderly closedown according to predetermined conditions to the disintegrating machine running status, make operating personnel in time stop disintegrating machine, analyzing failure cause; Fix a breakdown, thereby reach the normal purpose of moving of service equipment.System process is easy to realize that signals collecting is reliable that economic serviceability is good.

The specific embodiment
.1, bearing block among the figure, 2, temperature plugs in sensor soon, 3, crossover sub, 4, fast plug-in cable, 5, electric liquid comprehensive monitoring system, 6, bolt.
Can know by Fig. 1～4; The present invention plugs in sensor 2, crossover sub 3, fast plug-in cable 4, electric liquid comprehensive monitoring system 5 and bolt 6 soon by bearing block 1, temperature and constitutes; In the bearing block 1 at hammer axle assembly two ends, be respectively equipped with threaded ladder slotted hole; The slotting soon sensor 2 of temperature is made up of pedestal and the probe above it, and the pedestal left end is fixed together with bearing block 1 being threaded of ladder slotted hole porch, and it is inner that probe stretches into the ladder slotted hole; Crossover sub 3 tops are inserted in the slotting soon sensor 2 pedestal right-hand member holes of temperature and through screw and are fixed; Crossover sub 3 bottoms connect with fast plug-in cable 4, and fast plug-in cable 4 also connects electric liquid comprehensive monitoring system 5, and electric liquid comprehensive monitoring system 5 is fixed on disintegrating machine head backplate place through bolt 6.
Be respectively equipped with threaded ladder slotted hole in the bearing block 1 at hammer axle assembly two ends, be positioned at below, become the left and right sides of 45 with bearing block 1 axis horizontal line, i.e. A among Fig. 2 and B place near bearing outer ring, bearing block 1.Ladder slotted hole distance between center line bearing outer ring distance L is 20～25mm.During work, in the hole near operating personnel, easy operating is installed, another side opening is subsequent use when changing working face.
Operation principle: disintegrating machine is from starting to smooth working; The temperature of hammer axle assembly bearing is begun after certain temperature rise of short time, finally to remain on the stable temperature by the initial environment room temperature, and temperature is plugged in sensor 2 soon detected temperature simulation amount physical signalling is converted into the analog quantity signal of telecommunication; Through crossover sub 3 and fast plug-in cable 4 signal of telecommunication is uploaded to electric liquid comprehensive monitoring system 5; The analog quantity signal of telecommunication converts data signal again to; Liquid crystal display through electric liquid comprehensive monitoring system 5 demonstrates the actual physics numerical quantity in order to operating personnel's field monitoring; Data signal also can upload to the total Control Room in ground through teletransmission from the down-hole again, thereby reaches the monitoring to hammer axle assembly bearing arrangement.
If incidents such as not in place have taken place to lubricate; It is unallowed when high-order that the unusual or temperature of the bearing temperature rise that monitors reaches; Electricity liquid comprehensive monitoring system will send alarm indication, and equipment can automatic fault be shut down when the situation is critical, wait for that operating personnel do further processing; Safeguard that disintegrating machine normally moves, improved the reliability of disintegrating machine.
