Abstract

The utility model relates to a tamping device for stiffening foundation soil, comprising a machine frame. A supporting rod is arranged on the machine frame, and a fixed pulley is arranged on the supporting rod. Steel ropes are arranged along the fixed pulley, and a hanging frame is hung below the steel ropes. Each steel rope is hung below the hanging frame, and each steel rope is connected with a clamp-on claw hook through a fixed pulley block at the side corresponding to an automatic hook falling unit fixed on the supporting rod. The lower part of the claw hook can hold a hanging hook at the top part of a heavy hammer. In the process of lifting the heavy hammer, the device can realize the automatic exfoliation of the heavy hammer, thus improving the constructing efficiency.

Description

The present invention relates to the equipment that a kind of ground stabilization is used, this equipment can be used to structure foundation is tamped, and forms ground compaction, compaction pile.

The existing ground tamping apparatus of weight that utilizes comprises frame at present, frame is provided with vertical rod and weight promotes driver, and vertical rod is provided with fixed pulley, establishes steel cable along fixed pulley, this steel cable one end links to each other with the weight top, and the weight on an end and the frame promotes driver and links to each other.The shortcoming of the said equipment is can not discharge automatically after weight promotes, and consequently the impact compaction effort to ground stabilization is big inadequately, thereby the ground stabilization effect is bad and efficiency of construction is low.

The object of the present invention is to provide a kind of ground stabilization tamping apparatus, can improve foundation strength and efficiency of construction after lifting thereby this equipment can make weight discharge automatically.

Above-mentioned purpose of the present invention can realize by the ground stabilization tamping apparatus of following structures, this equipment comprises frame, frame is provided with vertical rod, vertical rod is provided with fixed pulley, also be provided with weight on the frame and promote driver, driver links to each other with steel cable one end, the steel cable other end links to each other with the compacting weight by above-mentioned fixed pulley, it is characterized in that being fixed with in the vertical rod automatic decoupling device, this detacher comprises support plate, each fixes one group of fixed pulley in the both sides of this support plate, hang with suspension bracket under the other end of above-mentioned steel cable, the both sides of this suspension bracket respectively are connected with a steel cable, wherein every steel cable extends downwards and passes laterally between two of this group fixed pulley from the fixed pulley group of a corresponding side is inboard, link to each other with the lifting hole(eyelet) of a corresponding side in the claw hook afterwards, above-mentioned claw hook comprises two jig arm, these two jig arm are intersected mutually and are hinged in the crosspoint, above-mentioned lifting hole(eyelet) is located at the top of jig arm, the bottom inside of jig arm is the hook-shaped suspension hook that is used for catching the weight top, and the outside spacing of the fixed pulley that is positioned at the below in the both sides fixed pulley group in the above-mentioned detacher is greater than the spacing of claw hook two lifting hole(eyelet)s on it when clamping weight.

Above-mentioned automatic decoupling device can slidably be fixed in the vertical rod.

The part that is positioned in the jig arm in the above-mentioned claw hook below the pin joint is semi-cylindrical.

The suspension ring at above-mentioned weight top are mushroom.

Be fixed with casing in the above-mentioned vertical rod, above-mentioned two steel cables that link to each other with claw hook pass this casing.This casing can be fixed in the vertical rod in the mode of sliding.

Advantage of the present utility model is the efficiency of construction height, and the energy height that tamps the foundations solid is dashed in compacting, and consolidation effect is good.

Equipment of the present invention can be used for the compacted pore-forming of the compacted or stake of the compacting of cinder pile, sand pile, lime soil pile, broken stone pile.

Below in conjunction with accompanying drawing the present invention is further described.

Fig. 1 is the overall schematic of present device;

Fig. 2 is the schematical top view of claw hook;

Fig. 3 is the sectional drawing along 1-1 line among Fig. 2;

Fig. 4 is the elevation of automatic decoupling device;

The attach most importance to schematic diagram of peen portion suspension hook of Fig. 5;

Fig. 6 is the plan view of suspension hook shown in Figure 5.

As shown in Figure 1, present device comprises frame 1, this frame 1 front portion is provided with vertical rod 2, also be provided with weight on the frame 1 and promote driver 3, vertical rod 2 tops are provided with fixed pulley 5, and steel cable 6 one ends are connected on the driver 3, its other end is walked around fixed pulley 5 and is linked to each other with suspension bracket 7 tops, be connected with two steel cables 8 and 8 ' below the suspension bracket 7, this steel cable 8 links to each other with claw hook 11 with casing 10 by detacher 9 with 8 ', and this claw hook 11 links to each other with the top suspension hook 22 of weight 2.Between vertical rod 2 and frame 1, be provided with oil cylinder 4, can be used to make vertical rod to rotate.

Shown in Fig. 2 and 3, claw hook 11 is by jig arm 13 and jig arm 14, and its top is provided with suspension ring 20 jig arm 13 and jig arm 14 is hinged by hinge 3, and jig arm 13 and 14 a section 21 below pin joint is semi-cylindrical, and lateral section is a spoonful shape in it, as shown in Figure 3.

As shown in Figure 4, automatic decoupling device 9 comprises support plate 19, support plate 9 is fixed in the vertical rod 2, be fixed with two groups of fixed pulleys on it, these two groups of fixed pulleys are arranged in the left and right sides, one group of the left side comprises fixed pulley 15 and fixed pulley 16, one group of the right side comprises fixed pulley 17 and fixed pulley 18, the spacing of fixed pulley 15 and fixed pulley 17 is less than the spacing of fixed pulley 16 and fixed pulley 18, and the outer rim spacing of fixed pulley 16 and 18 is greater than the spacing of claw hook two suspension ring 20, like this when the lifting weight arrives to a certain degree, because two steel cables 8 freely fall thereby the increasing of 8 ' spacing forces claw hook to open release weight 12.

Multiple shape can be adopted in the weight top, and than mushroom-shaped as illustrated in Figures 5 and 6, just this top is the mushroom-shaped suspension hook, thereby its middle part indent matches with the jig arm bottom of claw hook.Certain above-mentioned top suspension hook can also be sphere, polygon, taper.

Casing 10 shown in Fig. 1 can be made of steel pipe, and it mainly is to guarantee top, mating holes position, weight bottom and automatic decoupling device, thereby guarantees accurately to crash in the hole after weight breaks off relations.
