Abstract
The utility model belongs to the technical field of mine power shovel equipment, more particularly to a kind of power shovel air bag buffer.It includes the control system being located in power shovel operation driver's cabin and one group of bumper housings body being located on power shovel cantilever, one group of buffer air bag is correspondingly provided with one group of described bumper housings body, the air inlet of this group of buffer air bag is in parallel with an airduct, this airduct after pressure switch, check valve, pressure regulator valve, cleaner series connection with wind storage bag successively with being connected, described wind storage bag is connected with air pump or pressure wind source capsule, and described pressure switch, pressure regulator valve are connected with described control system.The utility model modification scheme is simple in construction, it is easy to implement, and improvement cost is low, it is ensured that power shovel does not have any injury to cantilever and connector after being impacted, it is ensured that the even running of equipment, reduces maintenance workload and reduces spare parts cost consumption.
Description
Technical field
The utility model belongs to the technical field of mine power shovel equipment, more particularly to a kind of power shovel air bag buffer.
Background technology
4 cubic meter electric shovels are, by helping handle to be hinged installation shovel bar, to shovel bar on mine industry mining large equipment, its cantilever
End is connected by connector with scraper bowl, in order to avoid being pushed against between connector and cantilever, and arrangement is provided with multiple on cantilever
Buffer, original buffer largely adds iron-clad or blob of viscose plus iron-clad two types for wood, though this two kinds of buffers can be preferably
Play cushioning effect, but it is larger to produce impulsive force when being due to the buffer work of two kinds of materials, so playing the same of buffering
When, buffer is in itself and cantilever and connector also due to hit and premature breakdown repeatedly, and the damage at three positions is often resulted in
Repair welding or replacing repeatedly, maintenance workload increase, the spare parts cost increase of operation area, rate can be started by having a strong impact on equipment.
The content of the invention
The purpose of this utility model there is provided a kind of air bag buffer, be pushed away by using pneumatic cushion to slow down
The impact of splenium position, it is to avoid the damage of buffer and cantilever and connector, reduces maintenance workload, and reduction spare part is damaged and cost
Consumption.
The purpose of this utility model is realized by following technical proposals：
Power shovel air bag buffer of the present utility model, including be located at power shovel operation driver's cabin in control system and be located at
One group of buffer air bag is correspondingly provided with one group of bumper housings body on power shovel cantilever, one group of described bumper housings body, this group
The air inlet of buffer air bag is in parallel with an airduct, this airduct successively with pressure switch, check valve, pressure regulator valve, filtering
Be connected after device series connection with wind storage bag, described wind storage bag is connected with air pump or pressure wind source capsule, described pressure after
Electrical equipment, pressure regulator valve are connected with described control system.
The utility model has the advantages that：
The utility model modification scheme is simple in construction, it is easy to implement, and improvement cost is low, it is ensured that power shovel impacted after to outstanding
Arm and connector do not have any injury, it is ensured that the even running of equipment, reduce maintenance workload and reduce spare parts cost and disappear
Consumption.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, power shovel air bag buffer of the present utility model, including the control being located in power shovel operation driver's cabin
One group of buffering is correspondingly provided with system and one group of bumper housings body 8 being located on power shovel cantilever 9, one group of described bumper housings body
Air bag 7, the air inlet of this group of buffer air bag is in parallel with an airduct 6, this airduct successively with pressure switch 5, unidirectional
Valve 4, pressure regulator valve 3, cleaner 2 are connected after connecting with wind storage bag 1, described wind storage bag 1 and air pump or pressure wind source capsule
It is connected, described pressure switch, pressure regulator valve are connected with described control system, the excitation contactor in control system
It is connected with pressure switch.
When buffer air bag 7 is hit by the connector at scraper bowl rear portion to be extruded, one is due to there is air bag to protect making contact
Position will not be damaged；Secondly because check valve 4 prevents wind backflow in pipe, wind overpressure increases, and pressure switch 5 is just acted as
With the control system in power shovel operation driver's cabin being connected with pressure switch 5 is connected to signal, and excitation contactor disconnects, department
Machine can not carry out bulldozing operation again, so as to avoid continuation impact damage buffer, cantilever and connector.
