Abstract
The utility model discloses a cross suspension device which is used in the hydraulic grab bucket, and comprises a connecting body, an upper connecting device and a lower connecting device; a bucket rod connecting hole is arranged at the upper end of a connecting rod; a grab bucket connecting hole is arranged at the lower end of the connecting rod; the axial line of the bucket rod connecting hole is vertical to the axial line of the grab bucket connecting hole. The hydraulic grab bucket adopts the cross suspension device; under the impact of the water flow or in the revolving movement of the mud loading and unloading process, the bucket body slants for a certain angle in the vertical direction and in the horizontal direction to reduce the arm of force; and the utility model prevents the bucket rod from bearing the huge bending torque, reduces the failure rate of the connecting part of the bucket rod and the hydraulic grab bucket, and improves the work efficiency.
Description
Technical field
The utility model relates to a kind of hydraulic grab link, particularly a kind of hydraulic grab cross suspension arrangement.
Background technology
Grab boat is the main tool of carrying out underwater cleaning work.The grab bucket of underwater hydraulic that dredge boat is used can be used for principal dimensions and drinking water are had the dredge boat of strict restriction, the operating mode that is applicable to that The turbulent river crashes its way through, and productivity ratio is higher.
The employing hinge is connected between the underwater hydraulic of prior art grab bucket grab bucket and the grab bucket bar, when water velocity is higher, at the certain angle that can only tilt in one direction under the impact force of water flow effect or in the gyration process of loading and unloading mud to reduce the arm of force, and bear huge moment of flexure at the inevitable dipper of other directions, it is frequent to make dipper be connected fault partly with hydraulic grab, has reduced work efficiency.
Therefore, need connector be set at dipper and bucket body, can tilt certain angle to reduce the arm of force at both direction at bucket body under the impact force of water flow effect or in the gyration process of loading and unloading mud, avoid dipper to bear huge moment of flexure, reduce dipper and be connected fault rate partly with hydraulic grab, improve work efficiency.
The utility model content
In view of this, the purpose of this utility model provides a kind of hydraulic grab cross suspension arrangement, can tilt certain angle to reduce the arm of force at mutually perpendicular both direction at bucket body under the impact force of water flow effect or in the gyration process of loading and unloading mud, avoid dipper to bear huge moment of flexure, reduce dipper and be connected fault rate partly with hydraulic grab, improve work efficiency.
Hydraulic grab of the present utility model cross suspension arrangement comprises connecting rod, and the connecting rod upper end is provided with the dipper connecting hole, and the connecting rod lower end is provided with the grab bucket connecting hole, the axis normal of the axis of described dipper connecting hole and grab bucket connecting hole.
Further, the circle two ends are provided with anti-wearing liner in the described dipper connecting hole.
The beneficial effects of the utility model are: hydraulic grab of the present utility model cross suspension arrangement, adopt cross distribution between dipper connecting hole on the connecting rod and the grab bucket connecting hole, during use, dipper connecting hole and dipper, the grab bucket connecting hole with the grab bucket between the employing hinge be connected, can tilt certain angle to reduce the arm of force at both direction in length and breadth at bucket body under the impact force of water flow effect or in the gyration process of loading and unloading mud, avoid dipper to bear huge moment of flexure, reduce dipper and be connected fault rate partly with hydraulic grab, improve work efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model structural front view;
Fig. 2 be the lateral view of Fig. 1 and along A-A to sectional view.
The specific embodiment
Fig. 1 is the utility model structural front view, Fig. 2 be the lateral view of Fig. 1 and along A-A to sectional view, as shown in the figure: the hydraulic grab of present embodiment cross suspension arrangement, comprise "
" word shape connecting rod 1, the connecting rod upper end is provided with dipper connecting hole 2, and the connecting rod lower end is provided with grab bucket connecting hole 3, and the axis of described dipper connecting hole 2 is right-angled intersection with the axis normal of grab bucket connecting hole 3; The grab bucket connecting hole 3 run through "
" word shape bottom bipod, guarantee connection stability; The circle two ends are provided with anti-wearing liner 4 in the dipper connecting hole 2, avoid circle wearing and tearing in the dipper connecting hole 2.
Dipper connecting hole on the connecting rod and grab bucket are adopted cross distribution between the connecting hole, and during use, dipper connecting hole and dipper adopt hinge to be connected between grab bucket connecting hole and the grab bucket, and circle is a friction pair in the dipper connecting hole, so anti-wearing liner is set on interior circle; Can tilt certain angle to reduce the arm of force at both direction in length and breadth at bucket body under the impact force of water flow effect or in the gyration process of loading and unloading mud, avoid dipper to bear huge moment of flexure.
Certainly, the shape of connecting rod 1 be not limited to "
" word shape, can be other shapes according to actual needs, or the like technical characterictic can change within the scope of the claims, do not influence the realization of the utility model purpose.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
