Abstract
The utility model relates to a displacement monitoring apparatus capable of displaying an axial movement of a roller, wherein the displacement monitoring apparatus is arranged inside a bearing pedestal at one end of the roller. The bearing pedestal includes a roller transmission portion and a detection portion; and a top pin spring extension assembly with a scale is axially arranged inside the bearing pedestal, wherein the top pin spring extension assembly penetrates the roller transmission portion and the detection portion. The top pin spring extension assembly (3) with a scale includes: a sword type shaft (14) of the top pin, which is contacted and connected with a roller shaft end surface arranged at the roller transmission portion; a sword type shaft bracket (16), which is arranged at the detection portion and supports the sword type shaft (14); the scale, which is arranged in the sword type shaft bracket (16), connected to the sword type shaft (14), and extended towards the outer end of the bearing pedestal; and a spring (15), which is sleeved at the periphery of the scale. According to the utility model, the bidirectional detection of the axial direction of the roller is realized by utilizing a sliding shaft spring extension mechanism principle. When the roller shaft is moved towards one side, the detected value of the scale at the rear end of the sword type shaft of the top pin is changed correspondingly.
Description
Technical field
The utility model relates to the induction system power transmission, and particularly, the utility model relates to a kind of displacement monitor of induction system power transfer member, and more specifically, the utility model relates to a kind of displacement monitor that can show the roller axial float.
Background technology
In each large industrial and mining enterprises, port and pier, carrying unit is the appliance arrangement that must be equipped with, and it is the lifeline that various raw materials are carried through whole system.
Take Baosteel mineral aggregate port as example, rubber conveyer is used for unloading and the transportation thereof of iron ore raw material.Article 49, sealing-tape machine supply line, the transport task that the ore of shouldering whole harbor district unloads, piles, gets, fills.Because carry the loose unpacked materials such as iron ore can realize continuously transportation under the handling condition continuously with rubber conveyer, so throughput rate is higher; The adhesive tape conveyer possesses simple in structurely in addition, and cost of equipment is low; Stable working is reliable, noise is little, and fed distance is long, and operational throughput is large, and the characteristics that energy resource consumption is few are so be widely used.
The conveying belt face width, the quality that are used for the mineral aggregate port are thick; And all be the metal inner lining conveying belt, so the component of conveying belt is heavy especially.On the other hand, for rubber conveyer, cylinder is the bearing part of convey materials, also is the traction piece of conveyor, thereby cylinder can claim the critical component of conveyor.Converyor roller mainly divides and drives and driven two classes because its importance, in case so damage can cause the paralysis of whole work flow, bring very large loss to production.
The damage of normal conditions bottom roll is mainly reflected in the following aspects: 1. drum rubber wearing and tearing, and this belongs to the normal consumption that embodies under the conventional operating position, is a kind of controlled abnormal state, and periodic law is generally arranged; 2. roller bearings damages, roller bearings damage usually and tenure of use with safeguard at ordinary times relevantly, but can pass through detection to its vibration and temperature, grasp its degradation trend; 3. the fracture of roller tube cracking and drum shaft, this belongs to a kind of abnormal abnormality, and general incidence is not high; 4. the axial float of cylinder, this is a kind of very hidden abnormality, incidence is higher, and, often can't realize in advance that by the monitoring of general temperature and vibration values it has ANOMALOUS VARIATIONS, check and test unless this roller bearing seat opened to find it is that the fixing sleeve of bearing has relaxed or safety plate has come off, axial displacement has occured in cylinder, needs to arrange fastening adjustment.Yet the whole induction system at mineral aggregate port often has hundreds of cover cylinder spare parts usually, if each cylinder is implemented regular strip inspection, spent stop time and maintenance load are with considerable.On the other hand, cylinder is altered axle in case occur, and will cause the bearing of a certain end of cylinder and bearing seat to damage, and the normal production order will be broken, and simultaneously, the damage reparation of cylinder being altered the axle generation is wasted time and energy.For example, change bearing and fixing sleeve, during the drum shaft serious wear, can only change roller assembly, generally all wanted do not wait in 5-10 consuming time hour.Thus, safety can not get ensureing that production efficiency is difficult to promote.
It is a kind of drum of damage form that cannot pre-control that cylinder is altered axle, and the main cause of its formation has: 1. fully locking of cylinder sleeve, and its reason has the bearing quality problem, also has the field engineering defective; 2. that section axle of cylinder sleeve installation position is by porphyrize, and this mainly is that deviation has appearred in the fit dimension of axle, or situation appearred in the locking tapering of sleeve; 3. after the sleeve locknut is locked into the position, because backstop is leveled up with the sleeve aperture position and is had angle difference, insurance step or 3 kinds of factors such as specification step have not just been abandoned, simultaneously, before the cylinder installation and maintenance, we want the play of monitoring bearing usually, to determine the tightening amount of set nut, in this process, it is excessive but usually can to appear at an opening part bearing clearance, and set nut is must forward next opening to the time, cause the too small practical problems of bearing clearance, cylinder can lose efficacy owing to the bearing fit excesssive gap makes sleeve in running up, and axial float occurs; Equally, also can be owing to bearing fit overhaul the too small heating, swollen dead unusual that produces, cylinder axial float accident occurs after causing damage of bearings.In prior art and the maintenance means, who can not guarantee to use the reliability of spare part fully, can not guarantee the standardization of installation dimension.Simultaneously, the prior art field does not have a kind of device and detection technique that can detect induction system cylinder generation axial float yet.
The utility model content
For addressing the above problem, the feature that the inventor shows during according to the work characteristics of cylinder and cylinder generation axial float, a kind of displacement monitor that can show the roller axial float is provided, the described displacement monitor of roller axial float that can show can in time have insight into roller bearing seat inside, because bearing clearance becomes delicate variation large or that the loosening axial float initial stage that occurs of sleeve shows, the convenient operation person in time implements counter-measure and maintenance scheme.
A kind of displacement monitor that can show the roller axial float, described displacement monitor be one with the thimble spring retractable mechanism of scale, utilize the effect of spring to come the variation of show rulers scale value, thereby judge that accurately unusually whether the cylinder axial float occurs.
The technical solution of the utility model is as follows:
A kind of displacement monitor that can show the roller axial float is arranged in the bearing seat of cylinder one end, it is characterized in that,
