Abstract

The utility model relates to a mechanical hammer hanging device. At present, most heavy ramming methods for building foundations are manual hook hanging methods, have large labor intensity and low work efficiency, are not safe, can create tilting phenomena sometimes and can not reach requirements of design easily. The mechanical hammer hanging device is composed of a hanging cylinder, a hanging hook and a hammer. The mechanical hammer hanging device is characterized in that the hanging cylinder, a locking fork and a mushroom head and a mushroom post are combined into a whole. A steel ball moves in a curved surface to automatically hang the hammer and disconnect the hammer. The steel ball mechanical operation replaces manual hook hanging methods. Thus, the mechanical hammer hanging device is safe, can increase work efficiency and can keep stabilization when the hammer is dropped.

Description

Power rammer automatic hammer-hanging device

A kind of machinery is hung the hammer device.

Current compacting to building lot soil, adopted dynamic compaction be about to hammer ram by artificial hook after,, break off relations suddenly again to certain altitude with crane lifting, utilize the hammer ram freely falling body to carry out soil compaction.This artificial hook Yet-have exists labour intensity big, and efficient is low, and it is complete to feel unwell, and because of friction also causes tilt drop, is difficult to reach designing requirement sometimes.

Top of the present utility model cover hook is enclosed within above the hook of former crane always, moves in hanging tube by steel ball with grinding fixedly hammer ram of aunt's post in the bottom, to realize that hanging hammer hammers action into shape with Off.The advantage of way is because steel ball does not have the fixed friction face like this, drops hammer steadily, and is durable in use, even do not tilt all can not keep the steady state of extension hammer out between two parties or slightly when hammer, Hai Neng Minus light work intensity is increased work efficiency, again safely and can overcome the inclination of dropping hammer.

Structure of the present utility model (seeing Fig. 1 Fig. 2) by suspension hook (23), hang tube (1) and hammer ram (15) and forms, is characterized in that hanging tube (1), a lock (2), locking and pitches (11), grinds aunt's post (4) and steel ball (3) combines:

One, hang tube (1): to hang a top be drop handle (12), be enclosed within that former suspension hook (23) is gone up, lock (2) is equipped with in the outside and locking fork (11), hang the tube middle part be embedded with steel ball (3) and steel ball guard ring (20), hang a bottom be connected with again horn mouth (7) and following horn mouth (6), in order to cover and hammer ram (15) be linked to be integral body mill aunt head (5), make it in place.

Two, lock (2): inner housing is that many gardens sphere shape and many steel balls (3) are tangent, and shell is provided with locking spring (22).

Three, locking fork (11): form by Brace in the wrong (8), drift angle (9), elastic spring (10), slide fastener (14) and stay cord (19), the end is established steel chain (14) and is joined with lock (2), the middle part is on pivot pin (16), drift angle (9) is housed, wheel trolley (18) is housed again on this drift angle to link to each other with Brace in the wrong (8), Brace (8) in the wrong links to each other and cooperates with elastic spring (10) again and plays a supportive role, and afterbody has its length of stay cord (19) to control the height that drops hammer.

Four, mill aunt's post (4) is welded into integral body with hammer ram (15), its upper end diameter enlarges part and is called Mo Gutou (5), bend and put down lock (2) when a mill aunt promotion drift angle in place (9) makes Brace (8) in the wrong, lock is then released steel ball (3) simultaneously, reaches to hang hammer.
