Description

The de-hammer of dynamic compaction machinery device
Technical field
The present invention relates to the de-hammer of a kind of dynamic compaction machinery device.
Background technology
Dynamic compaction machinery is the plant equipment for compacting foundation operation in engineering construction, it is mainly by repeatedly bringing up to hammer ram after certain altitude release, the powerful impact force of utilizing hammer ram free-falling to produce, reaches the object that improves foundation strength, reduction ground compressibilty, improves shock resistance and elimination ground settlement by soaking.When strong rammer operation, dynamic compaction machinery, by the auto-lock function of de-hammer device body, is lifted to certain altitude by hammer ram, and makes hammer ram free-falling after removing the self-locking that takes off hammer device under external force, completes and once rams operation.
At present, there are four defects in the de-hammer device that dynamic compaction machinery is conventional: 1, de-hammer wire rope is easily touched hammer ram, reduces de-hammer stability; 2, taking off hammer wire rope by flexibility carries tradition of suspension hook and detacher and combines and form the de-device of hammering into shape, de-hammer device free height after combination is high, not only reduce hammer ram hoisting depth and the specified usefulness of ramming, and increase the rolling momentum and the jitter time that after de-hammer, install, affect the operating efficiency of dynamic compaction machinery operation; 3, de-hammer device volume is large, while carrying out hammer ram lifting operation, must remove independently detacher, then hoisting rig is connected and could be realized with suspension hook, and workman hangs hammer difficulty, complicated operation; 4, the de-hammer of tradition device is manufactured complexity, cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide the de-device of hammering into shape of a kind of dynamic compaction machinery simple in structure, easy to operate, that operating efficiency is high.
For solving the problems of the technologies described above, the invention provides the de-hammer of a kind of dynamic compaction machinery device, comprise hoisting frame and suspension hook, lifting tackle group is equipped with in hoisting frame inside, described suspension hook comprises that the neck of hook section on top and suspension hook bottom have the hook section of holding that breach forms, hoisting frame lower end is hinged with link, and the lower end of link and suspension hook middle part are hinged, and link middle part is hinged with de-hammer assembly;
Described de-hammer assembly comprises de-hammer wire rope and stretches out the crossbearer in link outside, one end of crossbearer is hinged on the middle part of link, the other end of crossbearer is fixed with de-hammer wire rope top, de-hammer wire rope end is walked around the upper end of hoisting frame, and the position of the corresponding neck of hook section in middle part of crossbearer is provided with block axis.
Technology contents for a more clear understanding of the present invention, below installs de-this dynamic compaction machinery hammer device referred to as this.
Adopt after such structure, the hammer ram of dynamic compaction machinery is suspended on the suspension hook of this device, under hammer ram and the effect of suspension hook self gravitation, suspension hook rotates along link and suspension hook hinged place, the neck of hook section of suspension hook extends to the middle part of link, the neck of hook section on suspension hook top is resisted against in the block axis of crossbearer, now suspension hook is relative fixing with the position of hammer ram, and hammer ram hangs over the hook section of holding of suspension hook, can not make hammer ram depart from suspension hook, then hoisting frame drives this de-hammer device to be moved upward to after predetermined altitude, pull de-hammer wire rope end, crossbearer rotates to close hoisting frame upper direction along the hinged place of link and crossbearer, in this process, the neck of hook section of the block axis of crossbearer and suspension hook relatively moves, block axis moves until while not coming in contact with neck of hook section, suspension hook rotates under Action of Gravity Field, hammer ram is from the indentation, there landing of suspension hook, reach the object of de-hammer.
The crossbearer of this de-hammer device is hinged on link by bearing pin, and compared with the de-hammer of traditional dynamic compaction machinery device, it is simple in structure, opening is large, it is convenient to hang hammer, has improved workman's operating efficiency; And originally de-hammer device is connected hoisting frame by link with suspension hook, effectively reduces the free height of this device, has improved the stability of de-hammer.
The link of this de-hammer device comprises the junction plate of two parallel placements, and the upper end of two junction plates is hinged on the lower end of hoisting frame by bearing pin, and suspension hook is fixed between two junction plates by bearing pin;
Described crossbearer comprises the transverse slat of two parallel placements, and one end of two transverse slats is hinged with two junction plate middle parts of link respectively, and the other end of two transverse slats connects by fixed bar, and fixed bar is fixed with de-hammer wire rope top.
Adopt after such structure, the more reasonable structure of link and crossbearer, is also convenient between crossbearer and link and all parts hinged fixing more.
On the each junction plate of this de-hammer device, be fixed with two limited blocks, two limited block both sides up and down in corresponding transverse slat respectively.
Adopt after such structure, limited block has limited the slewing area of transverse slat, facilitates the location of transverse slat, and in avoiding using, the excessive machinery that causes of transverse slat pendulum angle misplaces.
In this de-hammer device block axis, roller is installed; Adopt after such structure, facilitate block axis and neck of hook section to relatively move.
In the hook section of holding of this de-hammer device, have the installing hole coordinating with shackle; Adopt after such structure, shackle is directly installed in installing hole, and hoisting rig can be realized weight lifting by being connected with shackle.
The hoisting frame top of this de-hammer device is provided with several directive wheels coordinating with de-hammer wire rope; Adopt after such structure, de-hammer wire rope is connected on crossbearer by several directive wheels, the top of de-hammer wire rope is away from dynamic compaction machinery operating desk position, realize this de-hammer in de-hammer device outside, de-hammer wire rope operates driver to the position of crossbearer active force away from dynamic compaction machinery, guarantee driver's safety, improve the vibratory impulse after the de-hammer of this de-hammer device.
