Abstract
Disclosed is a novel active drag head which comprises high pressure flushing holes, wear resistant blocks, rake teeth and wedge shaped tooth holders, wherein a plurality of pairs of high pressure flushing water hole are arranged, the wear resistant blocks are arranged outside each pair of high pressure flushing water holes, a wedge shaped interval is formed between the two adjacent wear resistant blocks, the rake teeth are directly welded on the wedge shaped tooth holders, and the wedge shaped tooth holders are installed in the wedge shaped intervals. The novel active rake head greatly shortens downtime due to repairing for damaged rake teeth and effectively improves construction efficiency.
Description
Technical field
The utility model relates to boats and ships construction equipment technical field, especially relates to a kind of novel active drag head.
Background technology
Active drag head is widely used in ship dredging construction, stronger to construction drawing sensitiveness, usually in order to adapt to excavation to clay, add weldering cutter type rake teeth at the active drag head front end, in the practice of construction process, buried dark or soil property really up to the mark, cutter type rake teeth fractures easily, even draw the wear-resistant block of bad weld, and the cutter type rake teeth that is welded once more need take many constructions and dredges the time, thereby reduces efficiency of construction and output, and influence is bigger if the welder technology level is low.
The utility model content
Goal of the invention of the present utility model is to invent a kind of novel active drag head, so that address the above problem.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of novel active drag head, comprise high-pressure flush hole, wear-resistant block, rake teeth and wedge shape toothholder, it is how right that described high-pressure flush hole has, every pair of described wear-resistant block of described high-pressure flush hole outer setting, the described wear-resistant block that faces mutually forms fixing wedge shape at interval in twos, described rake teeth directly is welded on the described wedge shape toothholder, and described wedge shape toothholder is installed in the described wedge shape interval.
Described wedge shape toothholder and described wedge shape between at interval fastening direction and described rake teeth be subjected to force direction identical.
Described rake teeth is a cutter type rake teeth.
The beneficial effects of the utility model are as follows:
1. the utility model has greatly shortened because of repairing the downtime of the rake teeth that damages, and has improved efficiency of construction effectively.
2. the utility model is simple in structure, and is cheap for manufacturing cost.
Description of drawings
Fig. 1 is the structural representation that the utility model master looks;
Fig. 2 is the structural representation that the utility model left side is looked.
The specific embodiment
Below in conjunction with accompanying drawing, describe the utility model optimized technical scheme in detail.
A kind of as depicted in figs. 1 and 2 novel active drag head, comprise high-pressure flush hole 2, wear-resistant block 3, rake teeth 4 and wedge shape toothholder, it is how right that described high-pressure flush hole 2 has, every pair of described wear-resistant block 3 of described high-pressure flush hole 2 outer setting, the described wear-resistant block 3 that faces mutually forms fixing wedge shape at interval in twos, described rake teeth 4 directly is welded on the described wedge shape toothholder, and described wedge shape toothholder is installed in the described wedge shape interval.Described wedge shape conforms to the outer contour shape of described wedge shape toothholder at interval.Interference fit between described wedge shape toothholder and the described wedge shape interval.Described rake teeth 4 is a cutter type rake teeth.
The wedge shape space of the utility model by the wedge shape toothholder being driven between the wear-resistant block 3, wedge shape little extreme direction at interval is subjected to force direction identical with rake teeth 4, stressed big more, described wedge shape toothholder and described wedge shape cooperating between at interval is fastening more, under rake teeth 4 buries stressed situation, compress toothholder automatically, only need during dismounting the wedge shape toothholder pounded out to big extreme direction and get final product.By to the improvement of active drag head and be equipped with the wedge shape toothholder of some, during construction, the wedge shape toothholder of the rake teeth 3 that only need damage when needing to renew after rake teeth fractures is changed and can be recovered construction, greatly shortened because of repairing the downtime of the rake teeth 3 that damages, improved efficiency of construction effectively.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of being done, be equal to replacement etc., all should be included within the protection domain of the present utility model.
Claims (3)
1. novel active drag head, it is characterized in that: comprise high-pressure flush hole, wear-resistant block, rake teeth and wedge shape toothholder, it is how right that described high-pressure flush hole has, every pair of described wear-resistant block of described high-pressure flush hole outer setting, the described wear-resistant block that faces mutually forms fixing wedge shape at interval in twos, described rake teeth directly is welded on the described wedge shape toothholder, and described wedge shape toothholder is installed in the described wedge shape interval.
2. novel active drag head according to claim 1 is characterized in that: described wedge shape toothholder and described wedge shape between at interval fastening direction and described rake teeth be subjected to force direction identical.
