Abstract
The utility model belongs to an online measuring device for measuring wearing depth of a pulley sheet rope groove of a crane, and particularly relates to an online measuring device for wearing depth of the pulley sheet rope groove for the crane. A measuring guide rod is mounted in a through hole of a fixed board through dynamic fit. A spring base is arranged on the part of a measuring guide rod below the fixed board. The part of the measuring guide rod between the fixed board and the spring base is provided with a compression spring. A base at the lower end of the measuring guide rod below the fixed board is provided with a roller. The measuring guide rod is provided with an initial scale and a wearing lower limit scale. In online measurement, the fixed board is fixedly mounted on a pulley base. The roller is matched with the bottom surface of the wheel groove of the pulley. The initial scale on the measuring guide rod is level with the upper surface of the fixed board. The online measuring device has advantages of reasonable structure and convenient operation. The online measuring device can intuitively measure wearing amount of the wheel groove of the pulley sheet and has high accuracy of measured data, thereby ensuring in-time changing of the pulley sheet which is worn to a preset value, and ensuring safe operation of the crane.
Description
Technical field
The utility model belongs to pulley sheet grooving wearing depth on-line measurement device for the on-line measurement device of measuring whip-gin sheet grooving wearing depth, particularly a kind of crane.
Background technology
Hoisting machinery definition and work characteristics: hoisting machinery be with intermittently, the working method that repeats, by the equipment of the hoisting of load-engaging device, decline or lifting migration material.
1. hoisting machinery has the mechanism of huge metal construction and more complicated conventionally, and overhaul of the equipments difficulty is larger;
2. the object of a handling is varied, and load changes, and handling process is normal complicated and dangerous;
3. most of hoisting machineries need to move in a big way, and activity space is larger;
4. each mechanism of hoisting machinery parts that expose, movable are more, and often directly contact with lifting job personnel;
5. operating environment is complicated; In operation, often need many people to coordinate, have larger difficulty;
6. hoisting machinery hoist rope elevating movement many accidental hazards etc. that lie dormant, as de-groove, the worn out damage that wire rope is caused of pulley until disrumpent feelings, bearing damage, wheel rim fracture etc.
The existence of above-mentioned many hazards, has determined that hoisting machinery injury accident mostly occurs.Hoisting machinery has been classified as special equipment special management in addition.
Conventionally the train that adopts fixed pulley group, running block, wire rope to form in hoisting machinery lifting mechanism.The Main Function of pulley is for changing the direction of motion of wire rope and arriving labour-saving object.Pulley is also commonly used for compensating pulley, the tension force of balanced two power wire rope.
The subject matter existing is as follows:
Pulley groove is comprised of wheel rim, spoke, wheel hub three parts, the bottom land of a circular arc of wheel cause and the sidewall of two inclinations form, that restriction wire rope is around the main device that enters and lay out, pulley groove contacts with wire rope simultaneously and produces and roll and sliding friction, will cause the wearing and tearing of pulley groove depth direction, cause in the course of time the wearing and tearing of pulley to scrap.
The depth direction wearing and tearing of pulley, can cause sidewall root thin, also can cause wheel rim inner side to produce corner angle, wire rope is caused to damage, when wearing depth continues to increase, the extrusion stress that the intensity of wheel rim sidewall root can not be born wire rope finally causes breaking, and causes steel cable slot disengaging, even cut off wire rope, cause large hoisting machinery security incident.
The maintenance standard of conventional hoisting machinery pulley sheet is periodic replacement, or regularly adopts measurement to check that the method for the bottom land degree of depth checks the abrasion condition of grooving, is subject to the impact of production process tissue, and this inspection method implements and has certain difficulty.
Utility model content
The purpose of this utility model is to provide pulley sheet grooving wearing depth on-line measurement device for a kind of crane, it is rational in infrastructure, easy to operate, can measure intuitively the wear extent of pulley sheet race, measurement data is accurate, the pulley sheet that may wear to setting with assurance is changed in time, guarantees crane safety operation.
The purpose of this utility model is achieved in that pulley sheet grooving wearing depth on-line measurement device for a kind of crane, in the through hole of fixed head, moving cooperation is installed with measurement guide rod, be positioned on the measurement guide rod of fixed head below spring base is being set, on the measurement guide rod between fixed head and spring base, Compress Spring is installed, on the bearing that is positioned at the measurement lower end of the guide rod below fixed head, roller is installed, initial scale and wearing and tearing lower limit scale are being set on measurement guide rod, during on-line measurement, on pulley base, be fixedly mounted with fixed head, roller matches with the wheel groove bottom of pulley, the initial scale of measuring on guide rod is concordant with the upper plane of fixed head.
The process that the utility model on-line measurement is installed and used is:
1. the fixed pulley system forming for many pulleys, can install a plurality of on-line measurement devices, can be by the comparison of measurement data, and accuracy and error that can matching measurement, formulation equipment reasonably overhauls the replacement cycle.
2. for the wearing and tearing upper and lower limit scale value marking on sliding guide, for the version of different fixed pulley groups, should measure respectively definite.
3. the initial scale value on guide rod should be concordant with the upper plane of fixed head, and the wearing and tearing scale value that rolls off the production line is illustrated in the top of initial scale graticule, and recommendation form is shown as the diameter of pulley value of lower limit after the initial diameter value of pulley groove and wearing and tearing, can avoid indicating value second Conversion; Owing to being that guide rod slides up and down, wear extent is linear relationship intuitively, can observe wear extent very intuitively, thus the degree of wear of reflection pulley groove.
4. for fear of the contact friction of guide rod head and pulley groove, will be designed to roller structure form by guide rod head, changing sliding friction is rolling friction, to reduce the error of indication of measuring after guide rod wearing and tearing.
5. this is measured guide rod and contacts with pulley groove bottom, and the acting force of dependence spring is pressed on bottom land, remains and the contacting of bottom land the measuring error of avoiding beating and causing.
6. the installation site of on-line measurement device sliding guide is positioned at pulley side below, avoids wire rope to interfere with it, and what measurement mechanism was measured is the diameters of bottom land, rather than the measurement indicating value of wire rope top.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
