Detailed description of the invention
To describe various embodiment of the present utility model below in detail, embodiment wherein in conjunction with the accompanying drawings and describe hereinafter.Although the utility model will be described in conjunction with illustrative embodiments, be to be understood that the utility model is not limited to these illustrative embodiments.On the contrary, the utility model not only comprises these embodiments, but also comprises various distortion, improvement.
As shown in Figure 1 to Figure 3, dynamic compaction machinery of the present utility model is hung tripping gear and is mainly included housing 2, three claw hooks 3, deck 6, limit element 10 and unhook power set etc., the top of housing 2 is provided with the connecting rod 11 connecting dynamic compaction machinery trailer system, cylindrically, bottom 22 is in flare openings on the top 21 of housing 2.
Three claw hooks 3 are arranged on housing 2 by bearing pin rotationally, have the first turned position (see figure 2) departed from the hammer ram hanger 12 of hammer ram 1 upper end and the second turned position (see figure 1) mounted with hammer ram hanger 12 separately.The top of hammer ram hanger 12 is formed as the band chamfering flange coordinated with the gib head 31 of claw hook 3 lower end, roughly in mushroom-head shape.
Deck 6 is positioned at the inner side on the cylindric top 21 of housing 2, and it is set to be elevated relative to claw hook 3, thus is back and forth elevated between the restriction turned position (see figure 1) and the permission turned position (see figure 2) allowing claw hook 3 to rotate of the rotation of restriction claw hook 3.The bottom of deck 6 is provided with the guide roller 4 coordinated with the inwall of housing 2, and when deck 6 is in restriction turned position, guide roller 4 contacts with claw 3.By arranging guide roller 4, deck 6 being elevated steadily, and being contacted with claw 3 by this guide roller 4, can reduce friction, improve flexibility ratio.
Limit element 10 is positioned at the inner side on the cylindric top 21 of housing 2 equally, it is set to coordinate with deck 6, be provided with the such reposition element of such as spring 13 between limit element 10 and housing 2, the radial direction along housing 2 between the restriction down position (see figure 2) making limit element 10 can decline at restriction deck 6 and the permission down position allowing deck 6 to decline moves back and forth.
Described unhook power set comprise the disengaging lever 8 being articulated with housing 2 and the driving element driving this disengaging lever 8 to rotate around its fulcrum 81, in the present embodiment, driving element includes and is positioned at cylinder 9 outside housing 2 and wire rope 7, wherein cylinder 9 rotates around its fulcrum 81 in the counterclockwise direction for promoting to depart from lever 8, wire rope 7 departs from lever 8 rotate in the counterclockwise direction around its fulcrum 81 for pulling, and then departs from lever 8 and promote deck 6 and rise.Owing to realizing pneumatic disengaging by cylinder 9, can be realized, with the disengaging of hammer ram 1, avoiding occurring accident at any height and position by driver's operation.This cylinder 9 has stronger protecting against shock, anti-vibration ability.Break down once cylinder 9, can also realize departing from setting height by operation wire rope 7.The position of described disengaging lever 8 between its fulcrum 81 and cylinder 9 application point is provided with the roller 5 of exerting pressure acting on deck 6 top, departs from lever 8 and is contacted with deck 6 by this roller 5 of exerting pressure, can reduce friction, improve flexibility ratio.
When the dynamic compaction machinery extension tripping gear of above-described embodiment is in the duty shown in Fig. 2, limit element 10 is in the restriction down position extended radially, deck 6 is in higher permission turned position under the effect of unhook power set and limit element 10, claw hook 3 is in the first turned position under Gravitative Loads, and now claw hook 3 and hammer ram hanger 12 depart from; When above-mentioned extension tripping gear is in the duty shown in Fig. 1, limit element 10 overcomes the elastic force of reposition element 13 and is in the permission down position of radially retracting under the effect of hammer ram hanger 12, claw hook 3 goes to the second turned position under the effect of hammer ram hanger 12, now claw hook 3 and hammer ram hanger 12 mount, meanwhile, deck 6 is in lower restriction turned position.
The operating principle that the dynamic compaction machinery of above-described embodiment hangs tripping gear is as follows: during initial state, and deck 6, in a high position, limits it by limit element 10 and declines, claw hook 3 be in shown in Fig. 2 by clockwise rotated position of conducting oneself with dignity.The pawl process of hanging contacts with the hammer ram hanger 12 of mushroom head when whole device falls to, by the deadweight of whole device, first limit element 10 backs down to position shown in Fig. 1 by hammer ram hanger 12, then claw hook 3 is pushed up position as shown in Fig. 1, at this moment deck 6 falls to low level as shown in Figure 1, restriction claw hook 3 rotates, and can start to lift by crane hammer ram 1; Detach procedure is when cylinder 9 or wire rope 7 will depart from lever 8 jack-up or pull-up, the roller 5 of exerting pressure departed from lever 8 contacts with deck 6, simultaneously by deck 6 jack-up, the guide roller 4 be arranged on deck 6 separates with claw hook 3, claw hook 3 rotates freely, realize the disengaging of hammer ram hanger 12 and this device, at this moment this device is in initial state again, starts next working cycles.As can be seen here, when the supporting dynamic compaction machinery of extension tripping gear of the present utility model uses, can increase work efficiency; Can realize grabbing hanging hammer ram by driver's operation, not need to be equipped with hook person, greatly cost-saving.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the present utility model design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
