Describe in detail according to the lifting appliance for dynamic compaction machinery of the present utility model below with reference to accompanying drawing.
As depicted in figs. 1 and 2, according to the lifting appliance 100 for dynamic compaction machinery of the present utility model, comprising: 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 links to each other with driving mechanism 101.
Detacher 107 links to each other with unhook oil cylinder 106.
Wherein, when driving mechanism 101 driving reels 104 turn to the first precalculated position, 102 pairs of driving mechanisms 101 of the first brake are 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 and breaks off relations.
According to the lifting appliance 100 for dynamic compaction machinery of the present utility model, when driving mechanism 101 driving reels 104 turn to the first precalculated position, 102 pairs of driving mechanisms 101 of the first brake are 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 and breaks off relations, thus, the impact that the hammer ram Condition of Sudden Unloading brings is born by reel 104 and second brake 105 this moment, impact and can not be delivered to the transmission system that is formed by reductor 103 and driving mechanism 101 etc., avoided the impact to transmission system, improve the reliability of complete machine, prolonged the application life of complete machine.
According to an embodiment of the present utility model, the lifting appliance 100 that is used for dynamic compaction machinery also comprises clutch 109, and clutch 109 links to each other with reel 104 with reductor 103 respectively.Thus, can make the on-off action of reductor 103 and reel 104 more reliable.
According to embodiment more of the present utility model, the lifting appliance 100 that is used for dynamic compaction machinery also comprises primary importance sensor (not shown).Described primary importance sensor links to each other to detect described first precalculated position of reel 104 with controller 108.Thus, can make according to the control of the lifting appliance 100 that is used for dynamic compaction machinery of the utility model embodiment more accurate.
According to a concrete example of the present utility model, the lifting appliance 100 that is used for dynamic compaction machinery also comprises second place sensor (not shown).Described second place sensor links to each other to detect the second precalculated position of described reel with controller 108.When reel 104 turned to described the second precalculated position, controller 108 control driving mechanisms 101 ran slowly.Thus, brake and before 105 pairs of reels 104 of second brake brake at 102 pairs of driving mechanisms 101 of the first brake, the process that a buffering is arranged has further improved the reliability according to the lifting appliance 100 that is used for dynamic compaction machinery of the utility model embodiment.
Need to prove that at this 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 control driving mechanisms 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 brake 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 and breaks off relations.This is understandable for the person of ordinary skill of the art.
According to an embodiment of the present utility model, driving mechanism 101 can be hydraulic motor.
According to a kind of dynamic compaction machinery of the present utility model, comprising: car body (not shown) and according to the lifting appliance 100 that is used for dynamic compaction machinery of the utility model above-described embodiment.The lifting appliance 100 that is used for dynamic compaction machinery is installed in described car body.
Based on according to the technique effect that has for the lifting appliance 100 of dynamic compaction machinery of the present utility model, also has corresponding technique effect according to a kind of dynamic compaction machinery of the present utility model.
Briefly explain the course of work according to the lifting appliance 100 for dynamic compaction machinery of the present utility model below with reference to Fig. 2.
After detacher 107 hung up hammer ram, controller 108 control driving mechanism 101(were hydraulic motor) rotate, hydraulic motor drives reel 104 by reductor 103 and rotates, and begins to promote hammer ram.
When second place inductor detected hammer ram and is promoted to the second precalculated position, controller 108 was controlled the rotating speed that reduces hydraulic motor by reducing hydraulic fluid flow rate, and then so that the hammer ram hoisting velocity is slack-off.
When the primary importance inductor detected hammer ram and is promoted to the first precalculated position, controller 108 controls stopped to hydraulic motor input hydraulic pressure oil.At this moment, 102 pairs of hydraulic motors of the first brake are 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 are broken off relations, and hammer ram falls.
According to the lifting appliance 100 for dynamic compaction machinery of the present utility model, because adopting clutch is reductor 103 and 104 to be opened/closed linking to each other of reel, 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 that is 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, prolonged 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.Because the lifting of reliability, operating efficiency improves, and economic benefit improves.
In the description of this manual, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although the above has illustrated and has described embodiment of the present utility model, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art in scope of the present utility model, can change above-described embodiment in the situation that does not break away from principle of the present utility model and aim, modification, replacement and modification.
