Description
Technical field
The invention belongs to rubber conveyer technical fields, and in particular to a kind of rubber conveyer gravity tensioning safeguard protection dress
It sets.
Background technology
With the fast development of the bulk cargos logistic industry such as Modern Port, harbour, storage, large conveying quantity, tilts high-altitude at long range
The rubber conveyer of installation is more and more.Existing rubber conveyer gravity is vertically tensioned mode, since its is simple in structure, tensioning
Reliably, easy to maintain and be used widely.But the fracture safe protective device of the tensioning mode generally used now makes
With with promote or a blank, high-level large conveying quantity rubber conveyer is especially installed, weight box and tensioning changed course rolling
The weight of cartridge module is usually constructed with several tons of weights.Once conveyer belt, which occurs, is broken the constraint that the component will be disengaged from conveyer belt, at itself
Under the action of gravity, lower ground is pounded with the acceleration of 9.8m/s2.Its breakdown strength will be destructive.Safety in production or the person
Casualty accident will be inevitable.
Some safety prevention measures exist in the prior art, but connect weight box and rack between mostly using steel wire rope,
Since it is rigid connection, several tons of heavy belt tensioning drums and weight box part, during freely falling body, kinetic energy（Kinetic energy=weight
Measure * instantaneous velocitys=weight * 9.8* fall times）Very big, destructive power is extremely strong, moment can break steel wire rope or cause rack
Gross distortion occurs, and then causes more serious safety accident, therefore corresponding protection purpose can not be played at all.
Invention content
The purpose of the present invention is in view of the above problems and insufficient, a kind of reasonable in design, compact, safety is provided
Performance is high, can realize automatic broken belt protector, and be applicable in the rubber conveyer gravity tensioning safety guard for being installed on high-altitude.
In order to achieve the above objectives, it is adopted the technical scheme that：
A kind of rubber conveyer gravity tensioning safety guard, including rack, gravity tensioning in frame lower is set
Vertically 90 ° of bend pulleys of tensioning and matching sliding are fastened on gravity tensioning sliding for sliding support, the gravity being arranged in rack
Gravity on holder is vertically tensioned 180 ° of bend pulleys and weight box, and safety protection component is both provided in rack both sides, described
Safety protection component include the buffer element being arranged in rack and setting buffer element it is vertical with gravity be tensioned 180 ° change
To the steel wire cable between roller.
The buffer element is buffering leaf spring, buffering leaf spring be multi-disc sheet arc spring steel plate different in size successively
It is folded to set connection, card slot corresponding with buffering leaf spring both ends is provided in rack, card slot bottom is provided with cambered surface and shores boss, blocks
Groove top portion is provided with buffering leaf spring spacer pin.
Bearing capacity M under the ultimate deformation amount of the described buffering leaf spring >=（M1+M2）/ 2, wherein M1It is vertically opened for gravity
The weight of tight 180 ° of bend pulleys, M2For the weight of weight box.
The buffering leaf spring both sides are fixedly installed two sliding racks by connecting bolt, and the matching of two sliding racks is crossed on machine
The both sides of frame, the steel wire cable upper end are connect with two sliding racks by axis pin.
Rack corresponding with sliding rack side is provided with guide groove, and sliding rack matching is fastened in guide groove.
Vertically 180 ° of bend pulleys of tensioning and weight box both sides are provided with support sliding rail frame, the steel wire to the gravity
Rope lower end is connect with support sliding rail frame.
The buffer element is rubber spring, butterfly spring, helical spring.
Using above-mentioned technical proposal, acquired advantageous effect is：
Overall construction design of the present invention is reasonable, is vertically tensioned on the installation foundation of both sides in original rubber conveyer gravity
One group of broken belt safety device is installed respectively, by connecting steel wire ropes rope respectively it is vertical with gravity be tensioned 180 ° of bend pulleys and
Weight box both ends are connected and fixed.When conveyer belt is broken, gravity is vertically tensioned 180 ° of bend pulleys and weight box starts certainly
By tensing connecting steel wire ropes rope while falling, the total weight of roller and weight box is acted on by connecting steel wire ropes rope
Onto buffering leaf spring group, cause to buffer leaf spring group being bent downwardly deformation, overcome counteracting roller and weight box to lower punch power.Most
Whole bend pulley and weight box are suspended in gravity and are vertically tensioned in sliding support, avoid the hair of safety in production and human casualty accident
Raw, the present invention integrally reequips conveniently, is convenient for the repacking to existing device, advantage of lower cost is convenient for promoting and answer
With.
The present invention buffers leaf spring during actual security protection, by setting, in the event of an accident, buffers leaf spring energy
It is enough stepped up the rated value of stress in steel wire rope and rack, while the kinetic energy of belt tensioning drum and weight box obtains alleviation gradually
It offsets, can will not thoroughly play due safety protection function there is a situation where instantaneously breaking steel wire rope or destroying rack.
