Abstract

The utility model discloses a combined high-strain test hammer which comprises a bottom hammer, middle hammers, a top hammer, screws and nuts fixing the screws, wherein the bottom hammer, the middle hammers and the top hammer are sequentially connected through the screws and the nuts, concave-convex connecting tenons which are fastened are arranged between the top hammer and the bottom hammer, and the middle of the top hammer is provided with a hanging ring. The combined high-strain test hammer solves the problem of matching of high-strain hammering equipment for different levels of high-strain tests in detection of foundation piles in the prior art, reduces resource waste and is applicable to different tons of large hammers for high-strain test. Besides, by the aid of the embedded screws, the combination of several hammers and the hanging ring, the large hammer is safer to assemble and has no special requirements for transport vehicles and hoisting.

Description

The high strain-gauge test hammer of a kind of combined type

Technical field

The utility model relates to the high strain-gauge test hammer of a kind of combined type, is mainly used in the high strain hammering equipment of high strain-gauge test different stage test in foundation pile detection.

Background technology

In the high strain detecting that foundation pile detects, the one hammer that the high strain hammer of existing employing is casting, test weight is in high strain loading test one very visual plant, according to code requirement, the weight of test weight can not be less than the 1%(that estimates ultimate bearing capacity as: estimate 500 tons of ultimate bearing capacities, require 5 tons of above hammers), in actual detection, the bearing capacity rank difference of engineering pile is very large, differ greatly above from 100 tons～2000 tons, according to code requirement as adopt monoblock cast, must be equipped with the sledgehammer of different stage, so not only waste, and the cost of transport and lifting is too large, in practical application, also there is combination hammer, adopt screw rod in the middle of every hammer body, to pass (being commonly called as punching combination hammer), when operating personnel are with hand steered positive screw rod assembling when this combination hammer assembling, easily there is danger, just in case breaking down, crane gear above cause hammer body to fall, operating personnel's hand is difficult to break away from the danger being injured by a crashing object.

Can find out in sum, there is following problem in existing high strain hammer: 1, a kind of overall hammer cannot complete different project detections; 2. the sledgehammer of tens of high tonnage tons, gets on or off the bus and wants large-tonnage crane, and will do special protection; 3. in existing punching combination hammer assembling process, easily cause danger, jeopardize operator safety.

Utility model content

The utility model object is to overcome the above-mentioned shortcoming that prior art exists, and provides a kind of combined type safe, convenient, applied widely high strain-gauge test hammer.

For achieving the above object, the technological means that the utility model adopts is: the high strain-gauge test hammer of a kind of combined type, comprise end hammer, middle hammer, top hammer, and the nut of the screw rod that three is connected successively and standing screw, between upper lower hammer, be provided with the concavo-convex joint tongue of snapping, described top hammer arranges one, is also provided with suspension hook at the middle part of top hammer; Hammer of the described end arranges one.

Further, hammer of the described end, middle hammer and top hammer are all symmetrical arranged a pair of hanger along diametric(al).

Further, the nut of described screw rod and standing screw arranges three groups altogether, the connected mode of itself and end hammer, middle hammer, top hammer is that outside is embedded, side in end hammer, middle hammer and top hammer all has the embedded groove corresponding with screw rod, is provided with screw head embedded groove on end hammer and the opposite of middle hammer joint face.

Further, the number of described middle hammer setting is 0 or 1 or multi-disc.

The beneficial effects of the utility model are: this structure has solved the matching problem of the high strain hammering equipment of high strain-gauge test different stage test in current foundation pile detection, reduce the wasting of resources, be suitable for the sledgehammer configuration of the high strain-gauge test of different tonnages, and adopt embedded screw rod and many hammers to combine and arrange hanger, make to assemble sledgehammer safer, upper lower hammer docks concavo-convex connection guarantees that sledgehammer globality is better, and haulage vehicle and lifting are not had to special requirement.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is front view of the present utility model;

Fig. 2 is upward view of the present utility model;

Fig. 3 is that upper lower hammer docks concavo-convex connection diagram.

In figure: 1, end hammer, 2, middle hammer, 3, top hammer, 4, screw rod, 5, nut, 6, suspension hook, 7, hanger, 8, embedded groove, 9, screw head embedded groove, 10, concavo-convex joint tongue.

Detailed description of the invention

The high strain-gauge test hammer of a kind of combined type as shown in Figure 1, 2, 3, comprise end hammer 1, middle hammer 2, top hammer 3, and the nut 5 of the screw rod 4 that three is connected successively and standing screw, between upper lower hammer, be provided with the concavo-convex joint tongue 10 of snapping, described top hammer 3 arranges one, is also provided with suspension hook 6 at the middle part of top hammer; Hammer of the described end 1 arranges one.

Further, hammer of the described end 1, middle hammer 2 and top hammer 3 are all symmetrical arranged a pair of hanger 7 along diametric(al).

Further, the nut 5 of described screw rod 4 and standing screw arranges three groups altogether, the connected mode of itself and end hammer 1, middle hammer 2, top hammer 3 is that outside is embedded, side in end hammer 1, middle hammer 2 and top hammer 3 all has the embedded groove corresponding with screw rod 8, be provided with screw head embedded groove 9 at end hammer 1, end hammer 1, middle hammer 2, top hammer 3 first snap together by the concavo-convex joint tongue 10 of hammering up and down joint face setting into shape, then lock by screw rod 4.

Further, the number that described middle hammer 2 arranges is 0 or 1 or multi-disc.

This flexible structure, can select hammer heavy according to test requirements document, and select suitable hammer combination (end hammer a slice according to hammer weight, top hammer a slice, middle hammer configures as requested), because monolithic hammer body is not heavy, can get on the bus by fork truck or small crane, after getting on the bus also without special protection device, arrive Assembling as Fig. 1, the crane gear that high strain field trial adopts is generally crane (or digging machine) and has participated in test, first catch on the hanger 7 of sheet hammer with wire rope, end hammer 1 is hung to ground, experimental area, then hanging lower hammer 2(operating personnel holds up hanger 7 to align), while hammer into shape in multi-disc, repeat middle hammer assembling, last top hammer 3, after top hammer 3 has been assembled, to embed assembling screw rod 4, tightening nuts 5, after assembling, can lift by crane suspension hook 6 tests.

The present embodiment is only with the explanation of this apparatus function of opposing, and or not as the restriction to this device, the simple replacement that those skilled in the art carry out according to this apparatus structure, is not included within the scope of the rights protection of this patent.
