Description

Stable buffering device of hammer lifting mechanism

Technical Field

The utility model relates to a pile foundation construction technical field, especially a carry stable buffer of hammer mechanism.

Background

In recent years, with the successful construction of a series of cross-sea bridges such as an east-sea bridge, a Hangzhou bay bridge, a gold pond bridge, a HongZhu-Australia bridge and the like, China gradually enters the world advanced level in the aspect of bridge construction technology. No matter bridge engineering or hydraulic wharf construction, pile foundation engineering is an extremely important ring. The pile driving boat is important ship equipment for pile foundation construction, and with the development of pile foundation construction technology, a high-energy hydraulic hammer is widely applied to the engineering, and is gradually becoming the standard matching of the pile driving boat.

In the process of pile driving construction by adopting the hydraulic hammer, the hammer lifting device is used as an intermediate link for driving the pile driving hammer to slide along the pile frame keel, plays an important role in bearing up and down, and is an indispensable important part. During the piling construction, the hammer lifting device is positioned between the hammer hanging pulley blocks of the piling hammer, and the safety and the reliability of the hammer lifting device are very important.

The original hammer lifting device of the 'iron pile 01' piling ship is a set of rectangular box type structure with pulley blocks at two ends, and the middle of the rectangular box type structure is connected with a lifting lug at the top of a piling hammer through a hinge pin shaft.

in the actual piling process, the following disadvantages exist:

(1) The guiding clamp structure cannot be manufactured to be thin due to too heavy weight and poor in strength. The pile sinking process is influenced by the installation clearance and often interferes with a guide plate at the top of the hydraulic hammer, so that the steel wire rope jumps, the abrasion is caused, the pile frame opening is deformed and the like.

(2) In the pile sinking process, if surge occurs, the jaw can irregularly shift up and down, left and right, and is extremely easy to clamp the pile frame opening, so that the abrasion of the opening is accelerated, even deformation and damage are caused, and the pile sinking efficiency is greatly reduced.

(3) In the pile sinking process, a specially-assigned person is required to observe the working condition of the hammer lifting mechanism all the time, if the jaw has the phenomenon of uneven stress, the machine must be stopped immediately, and the tension of the winch and the position of the ship are adjusted. Pile sinking efficiency is severely affected.

(4) the jaw is worn to a certain extent after being used for a long time, so that the gap between the jaws is too large, the jaws can deform during working, and the safety of personnel and equipment is damaged.

(5) The structural design is complicated, the installation and maintenance difficulty is high, and the cost is high.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor are within the scope of the present invention.

Referring to fig. 1 to 3 together, a preferred embodiment of the present invention is a stable damping device for a hammer lifting mechanism, which is disposed between a hammer lifting mechanism 2 and a pile hammer 3, and is composed of a damping unit 1, wherein the damping unit 1 includes a damping member 13 and a sleeve member, and the damping member 13 plays a role of damping. The buffering member 13 is fixedly provided with a tappet 14, the sleeve member is of a sleeve structure with an opening at the bottom, and the sleeve member is sleeved on the tappet 14 and can move up and down along the tappet 14. Because the sleeve is of a sleeve structure and is sleeved on the tappet 14, when the sleeve or the buffer 13 generates violent impact motion, air in the sleeve plays a role in buffering and damping. In this embodiment, carry hammer mechanism 2 and be one set of both ends and be equipped with the rectangle boxlike structure of assembly pulley, the centre is connected with 3 top lugs of pile hammer through a hinge point round pin axle, carries 2 sides of hammer mechanism simultaneously and is equipped with pile frame 4, is equipped with the guide rail on the pile frame 4, installs direction pincers 5 on the guide rail, pile hammer 3 side through welding or the mode of screw connection with direction pincers 5 fixed connection, pile hammer 3 realizes reciprocating through direction pincers 5 and guide rail. When the pile hammer 3 moves up and down due to surge or wind power and the like, the buffer assembly 1 plays a role in shock absorption and buffering, and the influence gap between the pile hammer 3 and the hammer lifting mechanism 2 is compensated.

further, the external member includes upper connecting piece 11 and lower connecting piece 12, and lower connecting piece 12 passes through bolt fixed connection with upper connecting piece 11 and is in the same place, and through the mode that 12 concatenations about adopting, the dismouting of the external member of being convenient for avoids influencing the installation and the dismantlement of other subassemblies because of the external member overlength. The upper connecting piece 11 is of a pipeline structure, and the top of the upper connecting piece is welded with the top of the hammer lifting mechanism 2 through a flange plate; the lower connecting piece 12 is of a pipeline structure with the same inner diameter as the upper connecting piece 11, and is fixedly connected with the upper connecting piece 11 through a flange edge and a bolt to form a kit.

Further, bolster 13 is rubber cushion pad, and is in the same place with 14 bottom pouring of tappet, adopts rubber as the material, has great bearing capacity, still has good resilience simultaneously, simultaneously through good shock attenuation buffer function, satisfies the shock attenuation buffering effect between lifting hammer mechanism 2 and the pile hammer 3.

Further, tappet 14 is open-topped tubular structure, and tappet 14 and the inside compression appearance chamber that forms of loop bar, when making because pile or because reasons such as surge appear impact vibration between pile hammer 3 and the hammer raising mechanism 2, the air in the compression appearance chamber can play the cushioning effect.

further, buffering subassembly 1 is equipped with four, centers on the lug and becomes four corners disconnect-type and arrange the junction between carrying hammer mechanism 2 and pile hammer 3, and at pile sinking in-process, it is even to carry hammer mechanism 2 atress, and the vibration is little, and the effectual hammer mechanism 2 of having avoided beats by a wide margin in the work progress, has guaranteed steel wire rope's safety.

During specific implementation, in the pile driving process of the pile driving hammer 3, the impact generated by pile driving is relieved, the service life loss of the impact between the pile driving hammer 3 and the hammer lifting mechanism 2 is reduced, meanwhile, the influence gap between the pile driving hammer 3 and the hammer lifting mechanism 2 is compensated, and the problem that the guide pliers 5 rub the guide rail of the pile frame 4 due to the fact that the hammer lifting mechanism 2 rubs in the pile sinking process is solved.
