Describe the lifting appliance for dynamic compaction machinery according to the embodiment of the present invention in detail below with reference to accompanying drawing.
As depicted in figs. 1 and 2, the lifting appliance for dynamic compaction machinery 100 according to the embodiment of the present invention comprises: driving mechanism 101, the first brakes 102, reductor 103, reel 104, second brake 105, unhook oil cylinder 106, detacher 107 and controller 108.
Specifically, the first brake 102 is connected with driving mechanism 101.
Reductor 103 is connected with driving mechanism 101 and reductor 103 can be opened and closed to be connected with reel 104.
Second brake 105 is connected with reel 104.
Detacher 107 is connected with unhook oil cylinder 106.
Controller 108 is connected with driving mechanism 101, the first brake 102 and second brake 105 and unhook oil cylinder 106.
Wherein, when driving mechanism 101 drives reel 104 to turn to the first precalculated position, the first 102 pairs, brake driving mechanism 101 is braked and 105 pairs of reels 104 of second brake are braked, and reductor 103 is thrown off with reel 104, and unhook oil cylinder 106 drives detacher 107 to break off relations.
The lifting appliance for dynamic compaction machinery 100 according to the embodiment of the present invention, when driving mechanism 101 drives reel 104 to turn to the first precalculated position, the first 102 pairs, brake driving mechanism 101 is braked and 105 pairs of reels 104 of second brake are braked, reductor 103 is thrown off with reel 104, unhook oil cylinder 106 drives detacher 107 to break off relations, thus, the impact that the hammer ram Condition of Sudden Unloading brings is now born by reel 104 and second brake 105, impact and can not be delivered to the transmission system formed by reductor 103 and driving mechanism 101 etc., avoided the impact to transmission system, improved the reliability of complete machine, extended the application life of complete machine.
According to one embodiment of present invention, for the lifting appliance 100 of dynamic compaction machinery, also comprise clutch 109, clutch 109 is connected with reel 104 with reductor 103 respectively.Thus, can make the on-off action of reductor 103 and reel 104 more reliable.
According to some embodiments of the present invention, for the lifting appliance 100 of dynamic compaction machinery, also comprise primary importance sensor (not shown).Described primary importance sensor is connected to detect described first precalculated position of reel 104 with controller 108.Thus, can make according to the control of the lifting appliance for dynamic compaction machinery 100 of the embodiment of the present invention more accurate.
According to a concrete example of the present invention, for the lifting appliance 100 of dynamic compaction machinery, also comprise second place sensor (not shown).Described second place sensor is connected to detect the second precalculated position of described reel with controller 108.When reel 104 turns to described the second precalculated position, controller 108 is controlled driving mechanism 101 and is run slowly.Thus, at 102 pairs of driving mechanisms 101 of the first brake, braked and before 105 pairs of reels 104 of second brake are braked, the process of a buffering arranged, further having been improved the reliability according to the lifting appliance for dynamic compaction machinery 100 of the embodiment of the present invention.
At this, it should be noted that, the hoisting depth that can make the first and second position sensors detect respectively hammer ram realizes detecting the first and second precalculated positions of reel 104.For example, set the first and second hoisting depths of hammer ram with corresponding the first and second position sensors, the first hoisting depth is higher than the second hoisting depth.When second place sensor detects the second hoisting depth of hammer ram, controller 108 is controlled driving mechanism 101 decelerates.When the primary importance sensor detects the first hoisting depth of hammer ram, 102 pairs of driving mechanisms 101 of controller 108 control the first brakes are braked and 105 pairs of reels 104 of second brake are braked, reductor 103 is thrown off with reel 104, and unhook oil cylinder 106 drives detacher 107 to break off relations.This is understandable for the person of ordinary skill of the art.
According to one embodiment of present invention, driving mechanism 101 can be hydraulic motor.
A kind of dynamic compaction machinery according to the embodiment of the present invention comprises: car body (not shown) and the lifting appliance for dynamic compaction machinery according to the above embodiment of the present invention 100.Lifting appliance 100 for dynamic compaction machinery is arranged on described car body.
The technique effect that the lifting appliance for dynamic compaction machinery 100 based on according to the embodiment of the present invention has, also have corresponding technique effect according to a kind of dynamic compaction machinery of the embodiment of the present invention.
Briefly explain the course of work according to the lifting appliance for dynamic compaction machinery 100 of the embodiment of the present invention below with reference to Fig. 2.
After detacher 107 hangs up hammer ram, it is hydraulic motor that controller 108 is controlled driving mechanism 101() rotate, hydraulic motor drives reel 104 to rotate by reductor 103, starts to promote hammer ram.
When second place inductor detects hammer ram and is promoted to the second precalculated position, controller 108 controls by reducing hydraulic fluid flow rate the rotating speed that reduces hydraulic motor, and then makes the hammer ram hoisting velocity slack-off.
When the primary importance inductor detects hammer ram and is promoted to the first precalculated position, controller 108 is controlled and is stopped to hydraulic motor input hydraulic pressure oil.Now, the first 102 pairs, brake hydraulic motor is braked, and 105 pairs of reels 104 of second brake are braked.
After reaching braking effect, controller 108 solenoidoperated cluthes 109 break away from, so that reductor 103 and reel 104 disconnect.Then, 106 actions of unhook oil cylinder, drag the rope that breaks off relations detacher 107 broken off relations, and hammer ram falls.
The lifting appliance for dynamic compaction machinery 100 according to the embodiment of the present invention, owing to adopting clutch, be that reductor 103 is connected with reel 104 is to be opened/closed, the impact that the hammer ram Condition of Sudden Unloading brings can be born by second brake 105 and reel 104, and impact force can not be delivered to the transmission system be comprised of reductor 103, driving mechanism 101 and the first brake 102 etc.Reduce the impact of Condition of Sudden Unloading to jib and complete machine, improved the reliability of complete machine, extended the application life of complete machine.Avoid the impact of Condition of Sudden Unloading to transmission system, improved significantly the operational reliability of transmission system, promoted the application life of reductor, each element of hydraulic pressure.Promoted user's operation comfort.Due to the lifting of reliability, operating efficiency improves, and economic benefit improves.
