Description
Technical field
The present invention relates to a kind of quarry tipper loading space shock mitigation system, belong to quarry tipper technical field.
Background technology
Quarry tipper is the key equipment in surface mine exploitation and extensive earthworks, is transported for ore or the earthwork
It is defeated, have the characteristics that load-carrying is big, operating efficiency is high, residing working environment is severe, and operating mode is complicated.Quarry tipper has court at present
The trend that large, hugeization direction are developed.
The loading capacity of large-scale mine dumper is big, has developed into 400 tons, during vehicle full-load run, huge load pair
The impact inertia and vibrate very big that loading space is formed.Loading space is connected with vehicle frame in tail end with bearing pin, and hole axle coordinates uses transition more
Coordinate with small―gap suture；Between cargo compartment bottom plate and longitudinal beam plus Rubber shock-absorbing pad is to reduce impact inertia and vibration, but uses
The middle abrasion for finding quarry tipper full load bearing pin and fatigue rupture are very serious, and quarry tipper full load, hundreds of tons
The impact of load is applied on vehicle frame by bearing pin, vehicle frame is born concentrfated load effect, is easily torn vehicle frame, so as to cause weight
Big security incident.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of quarry tipper loading space damping for avoiding connecting shaft stress
System.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of quarry tipper loading space shock mitigation system, including loading space, vehicle frame, damping device and connecting shaft, the damping device
It is distributed on the vehicle frame, for bearing the loading space weight, the vehicle frame afterbody is provided with the first mounting hole, under the loading space
Side corresponds to first position of mounting hole and is provided with the second mounting hole, and the connecting shaft is through first mounting hole and described the
Two mounting holes connect the loading space and the vehicle frame, the connection axle suspension when loading space is from idle condition to full-loading condition
Float in first mounting hole.
First mounting hole is equal with the second installation bore dia.
When the loading space is full-loading condition, the first mounting hole and second mounting hole are in concentric.
The connection shaft diameter is slightly less than the first mounting hole top and the second mounting hole bottom when the loading space is idle condition
The distance between end, the connecting shaft coordinate with first mounting hole and second mounting hole for small―gap suture.
The damping device is Rubber shock-absorbing pad.
Rubber shock-absorbing pad described in multiple row is distributed with along the vehicle frame length direction.
The beneficial effect that the present invention is reached：By rationally designing the decrement of damping device under different operating modes, matching connects
The size and position of spindle and mounting hole, ensure that loading space full load is not present and transmit showing for impulsive force by connecting axial vehicle frame
As load is all delivered on vehicle frame by damping device, is made vehicle frame uniform force, is avoided stress concentration；During loading space zero load, even
Spindle automatically adjusts with mounting hole to be coordinated for small―gap suture, can avoid slip of the loading space on vehicle frame.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Figure 1 to Figure 3, a kind of quarry tipper loading space shock mitigation system, including loading space 1, vehicle frame 2, Rubber shock-absorbing pad 4
And multiple row is distributed with along the length direction of vehicle frame 2 from headstock to the tailstock in connecting shaft 3, Rubber shock-absorbing pad 4, the afterbody of vehicle frame 2 is provided with
First mounting hole 2-1, the corresponding first mounting hole 2-1 positions in the downside of loading space 1 are provided with the second mounting hole 1-1, and connecting shaft 3 passes through first
Mounting hole 2-1 and the second mounting hole 1-1 connect loading space 1 and vehicle frame 2, and the first mounting hole 2-1 and the second mounting hole 1-1 are straight
Footpath is equal, and its diameter is set as D, and the diameter of connecting shaft 3 is set as d；
When loading space 1 is full-loading condition, the first mounting hole 2-1 and the second mounting hole 1-1 are in concentric, fully loaded by calculating
When goods and loading space to the decrement a of Rubber shock-absorbing pad 4, when making quarry tipper full-loading condition, the second installation on loading space 1
The first mounting hole 2-1 on hole 1-1 and vehicle frame 2 is in concentric as shown in Figure 4, and connecting shaft 3 does not stress, with the first installation
Hole 2-1 and the second mounting hole 1-1 contact frees.Now it is not present between loading space 1 and vehicle frame 2 and impulsive force is transmitted by connecting shaft 3
Phenomenon, load is all delivered on vehicle frame 5 by damping device 4, makes the uniform force of vehicle frame 5, avoid stress concentration；
In idle condition, load is only the deadweight of loading space 1, the overall weight of loading space 1 and goods during significantly less than full-loading condition,
Therefore, the decrement of Rubber shock-absorbing pad 4 between loading space 1 and vehicle frame 2 diminishes, and now loading space is b to the decrement of Rubber shock-absorbing pad.Ore deposit
With the fully loaded difference x=a-b with the deflection of Rubber shock-absorbing pad during Light Condition of dumper, the difference x of the deflection is also mining self-unloading
The fully loaded variable quantity with mounting hole center during Light Condition of car.Therefore, quarry tipper is in idle condition, the first mounting hole 2-
The distance between 1 top and the second mounting hole 1-1 bottoms are D-x, and the diameter d of connecting shaft 3 is slightly less than D-x, so that unloaded work
During condition the connecting shaft 3 of loading space 1 and vehicle frame 2 with being combined into small―gap suture cooperation, as shown in figure 5, avoiding during due to zero load loading space 1 to rubber
The pressure of glue beam 4 diminishes, between loading space 1 and vehicle frame 2 friction reduce and caused by cunning of the loading space 1 on vehicle frame 2
It is dynamic.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
