Abstract
A tensioning device with tension and gravity capable of being adjusted synchronously and on the lower portion of an elevator comprises a counter weight mechanism (device) and a lever. A lever adjusting mechanism (device) is installed on an enclosure on the lower portion of the elevator and connected with one end of the lever, the other end of the lever is connected with the counter weight mechanism, the middle of the lever is connected with a lever rotation shaft mechanism (device) through a sliding supporting plate, and the lever rotation shaft mechanism is connected with a steering chain wheel assembly or a belt pulley assembly on the lower portion of the elevator. The lever adjusting mechanism is a nut lead screw mechanism. A left tensioning device with tension and gravity capable of being adjusted synchronously and on the lower portion of the elevator on the lower portion of the elevator and a right tensioning device with tension and gravity capable of being adjusted synchronously and on the lower portion of the elevator are arranged on the lower portion of the elevator. The tensioning device is balanced in tension, effectively prevents the steering chain wheel assembly or the belt pulley assembly on the lower portion of the elevator from deviating from a chain or a belt, and is reliable in running.
Description
Technical field
The utility model relates to loose unpacked material gig bottom a kind of tightening device, the particularly tensioning of bucket elevator bottom change course device.
background technology
Tightening device is indispensable part in gig.Chain bucket or band bucket are in use because the factors such as self gravitation, work tensile stress, skimming wear will cause elevator chain or elevator belt anamorphic stretching.Along with the prolongation of time, elevator chain or elevator belt elongation constantly increase, and will cause the phenomenons such as sprocket wheel and elevator chain, belt wheel and the de-chain of elevator belt generation or de-band, trailer, increase load, the normal operation of the equipment that has a strong impact on and device security.General tensioning mode has:
1, bolt and nut tightening regulator: screw rod is assemblied on lower casing fixed bearing, nut is assemblied in the U-shaped groove of sliding support plate, in the time of rotary screw, just can make sliding support plate move up and down, the bearing seat of bottom changed course chain wheel assembly or changed course pulley assemblies is fixed on sliding support plate, thereby can make lower chain wheel assembly or pulley assemblies by elevator chain or elevator belt tensioning.This mode has distinct disadvantage: the one, and screw take-up need to operate while adjusting manually, requires equipment out of service simultaneously, and after adjustment work completes, row starting outfit operation again, will affect normal production, and also there is certain potential safety hazard in manual shift; The 2nd, screw take-up needs timely adjustment, and people likely forgets or other reasons is postponed and being regulated, and can not regulate in time and the situations such as de-chain or de-band, trailer, increase load occur; The 3rd, in the situation that can not realizing artificial timely adjustment, tensile force is unbalanced, is generally first tight rear pine after regulating.When manual shift, the size of tensile force is uncontrollable and definite, completely with artificial sensation and experience; The 4th, screw take-up is rigidity structure, and it is as serious in jam that bucket elevator takes material, will cause and promote hopper and screw rod distortion, and control apparatus lost efficacy, or causes serious equipment loss.
2, weight arm tightening device: one end of lever is fixed on by lever shaft pin on the roller pin bearing of gig lower casing, other end ballast weight hammer piece, interior card compaction forces is acted on and is connected on support plate by hinges, connect support plate and be connected on the bearing seat of bottom changed course chain wheel assembly or pulley assemblies by hinges, thereby make bottom changed course chain wheel assembly or pulley assemblies by elevator chain or elevator belt tensioning.This mode shortcoming: the one, structure is not compact to take up room greatlyr, and movement weight mass requires more, and adjustment travel is shorter; The 2nd, the lever arrangement angle on both sides can not realize synchronization regulation, and movement weight mass pressure is inhomogeneous, easily causes and lays particular stress on, and causes the situations such as monolateral de-chain, de-band, trailer, increase load; The 3rd, tensioning pressure is unbalanced, because of after installing and regulating, has weight one end to start to be upturned, along with the elongation of elevator chain or elevator belt, after hang low again downwards, lever angle constantly changes, tensioning pressure constantly changes thereupon; The 4th, under severe working environment, easily rust is dead for a long time for lever shaft pin and link pin, causes rotation dumb, and regulating rotary actuation mechanism lost efficacy.
Summary of the invention
The purpose of this utility model is mainly for above-mentioned prior art defect, provide one not need equipment out of service, and can realize the gig bottom synchronous adjustable tension gravity tensioning device of synchronous adjustable weight power, comprise heavy hammer mechanism (device), lever, lever one end connects heavy hammer mechanism, lever middle part connects lever shaft mechanism (device) by sliding support plate, lever shaft mechanism connects gig bottom changed course chain wheel assembly or pulley assemblies, lever regulate mechanism (device) is arranged on gig lower casing and connects the lever other end, lever regulate mechanism is nut-screw rod structure.
Gig bottom synchronous adjustable tension gravity tensioning device is preferably in left and right on gig lower casing and respectively installs one group.
The utlity model has following characteristics:
1, adopt lever construction principle, produce the tensioning pressure of several units with the gravity of 1 unit, laborsaving, reduce costs;
2, each one group around (adding up to two groups) synchronous adjustable gravity tightening device is arranged at each cover gig bottom.Adopt weight (quantity can increase according to actual needs and reduce) at gravity end, the other end is designed to the nut-screw rod structure of larger adjustable stroke, and middle tensile force place adopts hinges to connect.Can guarantee that left and right gravity tensioning device adjustment is synchronous on the one hand, prevent gig chain bucket or band bucket sideslip, the adjustable lever that makes remains horizontality on the other hand, tensile force equilibrium, effectively prevent the de-chain of gig bottom changed course chain wheel assembly or pulley assemblies or de-band, equipment is reliable;
3, adjustment travel is large, and (initial installation site) cycle that resets is long, and maintenance, easy to maintenance, reduces maintenance cost.
4, normality short travel setting nut screw mandrel, makes lever remain horizontality, in equipment running process, can realize, do not need shut down and the equipment that affects normally moves.
accompanying drawing explanation
Fig. 1 the utility model integral structure schematic diagram.
The specific embodiment
As shown in Figure 1, gig bottom synchronous adjustable tension gravity tensioning device, comprise heavy hammer mechanism 6, lever 5, lever regulate mechanism 1 is arranged on gig lower casing 4 and connects lever 5 one end, lever 5 other ends connect heavy hammer mechanism 6, lever 5 middle parts connect lever shaft mechanism 3 by sliding support plate 2, and lever shaft mechanism 3 connects gig bottom changed course chain wheel assembly or pulley assemblies.
Lever regulate mechanism 1 is nut-screw rod structure, comprises and regulates screw mandrel, setting nut, jam nut, feed screw nut's fixed bearing, screw mandrel to connect rotating shaft, rotating shaft locating dowel pin or collar.
Sliding support plate 2 on bearing seat comprises lever shaft supporting seat, sliding panel.
Lever shaft mechanism 3 comprises that lever connects rotating shaft, rotating shaft setscrew nut and nut lock washer.
The structure of lever 5 comprises shaft seating and lever.
