Abstract

The utility model relates to a front positioned pile-pressing machine. A main beam is connected with a front ship, a rear ship, a left ship and a right ship to form the pile-pressing machine. The pile-pressing machine can walk forward, backward, leftward, rightward and in the gyration mode. The utility model is characterized in that a hanging machine is arranged on the center of the pile-pressing machine; both ends of the front ship extends and enlarges toward the outer side of the pile-pressing machine on the horizontal direction; a pile-pressing mechanism is fixed on the main beam and is positioned on the outer side of the front ship. The utility model solves the problems that the distance of the utility model and the obstacle must be larger than 2.5 m and does not press a side pile and a corner pile in the narrow space. The utility model has the small distance of the side pile for 0.8 m and the small distance of the corner pile for 0.8*2.9 m.

Description

Front-located mode pile press

The utility model belongs to a kind of equipment of placing stake, specially refers to method of press-fitting skirt piles are pressed into underground equipment.

Existing static pile press, the sort of pile press described in Chinese patent 87105168, body is big, its piling mechanism is in fuselage central authorities, so want at least more than 2.5 meters from the distance of obstruction in the stake, the ability piling, and in the stake from the distance of obstruction during less than 2.5 meters, as usual transform in the city, the place is narrow and small, (descend) pipeline flanging stake for a long time, angle stake on the ground, must be equipped with other kind just can finish, or adopt increase skirt piles machine to finish piling work, thereby cause claim for eot, expense increases.

The purpose of this utility model is, designs a kind ofly can carry out various pressing pile constructions in narrow and small place in the place, comprises the front-located mode pile press of flanging stake and angle stake.

The utility model structure is such, ship before connecting by girder, back ship, left ship, right ship and form a kind of machine, this machine can carry out front and back walkings, about walking and revolution, loop wheel machine is arranged on the central authorities of described stake machine, expansion is stretched out in the horizontal direction in the two ends of preceding ship outside described stake machine, piling mechanism is fixed on the girder and places the outside of preceding ship.

The outside of ship before the utility model is contained in piling mechanism, loop wheel machine is arranged on central authorities, making the distance of the nearest obstruction of distance in the stake is 0.8 meter (distances of the skirt piles of promptly constructing), the nearest perpendicular type obstruction of distance is 0.8 * 2.9 meter (distance of the angle stake of promptly constructing) in the stake, above-mentioned two distances are dwindled greatly than pile press in the past, again because piling mechanism is arranged on the outside of whole stake machine, so can not impact and destroy during construction to obstructions such as place External building thing and underground (on the ground) pipelines.

Present embodiment is such, form a kind of machine by ship 11, back ship 9, left ship 13, right ship 10 before girder 16 connections, this machine can carry out front and back walkings, about walking and revolution, loop wheel machine 6 is arranged on the central authorities of above-mentioned stake machine, expansion is stretched out at the two ends of preceding ship 11 in the horizontal direction outside machine, piling mechanism 3 is fixed on the girder 16 and places the outside of preceding ship 11.

As shown in Figure 1: girder 16 is connected with preceding ship 11, back ship 9, right ship 10, and loop wheel machine 6 is arranged on central authorities, and piling mechanism 3 is fixed on the girder 16 and places the outside of preceding ship 11.For whole stake machine center of gravity is reduced, preceding ship 11 and back ship 9 are provided with counterweight 12 and counterweight 8 respectively; Girder 16 is provided with counterweight 7 and counterweight 6 and places the top of back ship 9 and preceding ship 11 respectively, and piling mechanism 3 also can be provided with counterweight 4; Piling mechanism 3 comprises clamping platform 1 and piling frame 2, and clamping platform 1 is contained in the piling frame 2 and can moves up and down in piling frame 2.

As shown in Figure 2: form a kind of machine by ship 11, back ship 9, left ship 13, right ship 10 before girder 16 connections, this machine can carry out front and back walkings, about walking and revolution, loop wheel machine 6 is arranged on the central authorities of described stake machine: when piling mechanism 3 works in preceding ship 11 outsides, in order to reduce the possibility that causes the machine of falling into because of the ground bearing pressure deficiency, so that expansion is stretched out at the two ends of preceding ship 11 in the horizontal direction outside machine, preferably Shape, only a side enlarges outside machine.

As shown in Figure 3: clamping platform 1 is contained in the piling frame 2, and clamping platform 1 moves up and down in piling frame 2 by several guide rails 14.Clamping platform 1 is provided with a hole 15.

During piling, ship 11, back ship 9, left ship 13 and right ship 10 before moving earlier make a hole 15 aim at a following position, with loop wheel machine 6 hole 16 is put in stake, by clamping platform 1 pile holder is held fixingly, the reaction force by the pressure of oil cylinder 17 and whole stake machine is pressed into stake in the preposition; Piling mechanism 3 move left and right just can the flanging stake, during the two ends of ship 11, just can press apart from the nearest angle stake of obstruction before piling mechanism 3 moves to.
