Abstract

The utility model relates to an assembled punch, which comprises a hoist 1, a machine frame 2, a rotator 3, a weight body 4 and a hammer head 5. The utility model is characterized in that a cavity is arranged in the weight body; a chamber is loaded with a weight block 6; the hammer head 5 connected with the weight body 4 is hollow; the upper end of the hammer head 5 is provided with a vent hole. The utility model has the advantages of high stake-hole quality, low hole-collapse rate and simple operation. The utility model is particularly suitable for pile-foundation drilling construction in the construction of buildings.

Description

The combined type punching device

The utility model relates to a kind of auger, especially a kind of perforating device that is applicable to pile foundation boring in the building operations.

For the deep foundation of building, generally all adopt the form of pile foundation at present; Existing pile foundation boring technology is divided into two types, a kind of is dry drilling, as the rotating boring of Luo, vibrating type pore-forming etc., it has, and speed is fast, the measured characteristics of stake concrete matter, but it all can not be constructed for large aperture, the geology that contains the boulder stone riprap, the bad ground etc. that embeds basement rock.Another kind of is that ability of swimming is holed, as percussive drilling, the boring of diving drill machine formula, rotary drilling rig boring etc., though this rig can solve the deficiency of dry drilling machine, but speed is slow, and efficient is low, often occurs the hole accident of collapsing in the work progress, the stake concrete is of poor quality, especially Zuan Kong aperture super large causes concrete amount many, waste material.

The purpose of this utility model is that design is a kind of high-quality and efficient, easy and simple to handle, is applicable to the combined type punching device of various earth formations.

The purpose of this utility model is to realize by such technical scheme, the utility model includes hoist engine, frame, rot, weight body and tup, it is characterized in that: in the weight body cavity is arranged, be filled with pouring weight in the chamber, the tup hollow that is connected with the weight body, there is steam vent the tup upper end.During use, can change the weight of weight at the weight body with interior increase and decrease pouring weight, according to different earth formations, select corresponding tup, punch, the gas in the tup cavity can be discharged by steam vent, until the degree of depth that reaches a hole.

Owing to adopt technique scheme, the utlity model has following advantage:

1. the aperture standard of getting, hole wall is firm, and verticality is good, stake concrete quality height.

2. except that beating rock with the low amounts of water, the hole of getting is a dry hole substantially, and the hole accident rate of collapsing is low.

3. the saving material is economical and practical.

4. simple to operate, be convenient to maintenance.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

The attach most importance to structural representation of hammer body of Fig. 2;

Fig. 3 is the structural representation of tup of fetching earth;

Fig. 4 is the structural representation of reaming tup;

Fig. 5 is the structural representation of rock punching head;

Fig. 6 is the structural representation of core crushing head.

Among the figure: 1. hoist engine; 2. frame; 3. rot; 4. weight body; 5. tup; 6. pouring weight; 7. steam vent; 8. metal coupling; 9. projection; 10. wedge type block; 11. the cone-shaped metal piece, 12. mouths that fetch earth.

Below in conjunction with drawings and Examples the utility model is further specified:

As shown in Figure 1, the utility model includes hoist engine 1, frame 2, rot 3, weight body 4 and tup 5, it is characterized in that: in the weight body 4 cavity is arranged, be filled with pouring weight 6 in the chamber, as shown in Figure 2, tup 5 hollows that are connected with weight body 4, tup 5 not-go-end have steam vent 7.During use, can change the weight of weight at the weight body with interior increase and decrease pouring weight, according to different earth formations, select corresponding tup, punch, the gas in the tup cavity can be discharged by steam vent.For the ease of changing tup, the employing latch is connected between weight body 4 and the tup 5.

As shown in Figure 3, for general earth formation, can select this tup that fetches earth for use, get diameter and be 300 millimeters stake hole, during punching, soil block enters in the cavity of tup, and intracavity gas can be discharged by steam vent, after soil block is filled, hang out tup, drive and to go in the tup cavity to continue punching, until the degree of depth that reaches a hole behind the soil block.Tup 5 middle parts have fetch earth mouthful (12), so that take out soil block from tup 5; In order to reduce weight body 4 and tup 5 and a friction of hole inwall, improve work efficiency, tup 5 lower end external surfaces intrinsic one all metal couplings 8.

When the more wide-aperture stake of needs hole, select the corresponding reaming tup in aperture for use, as shown in Figure 4, the stake hole of getting with the tup that fetches earth is basic hole, during reaming, the soil of reaming is fallen in the basic hole, after treating that soil in the basic hole fills up, change tup into the tup that fetches earth, take out the soil in the basic hole, continue reaming with the reaming tup again, thereby reach the purpose of reaming.For the soil that makes reaming is fallen in the basic hole, the intrinsic projection 9 of tup 5 lower end inner surfaces.

Earth formation or working design for boulder, stone riprap require stake to embed the basement rock of certain depth, select rock punching head for use, as shown in Figure 5, during punching, inject an amount of water, adopt the impact mode of high-frequency low clearance, impact while rotating, make a hole form the middle looping pit that Shi Xin is arranged, when the stone core height in the looping pit is close with tup cavity inner height, change tup 5 into the catalase head, as shown in Figure 6, the stone core is smashed, take out ground with screenings handle for bucket rubble slurry, carry out so repeatedly, till the stake hole depth that reaches the working design requirement.In order to make rock punching head pound crushed rocks, tup 5 lower end pipes are along the wedge type block 10 of idiozona cutting edge.For the catalase head hammer dynamics of pounding is concentrated, pound the rubble core easily, the intrinsic cone-shaped metal piece 11 in tup 5 lower ends, the wedge type block 10 of downward idiozona cutting edge on cone-shaped metal piece 11.
