Abstract

The invention discloses an underwater hydraulic grab bucket which is suitable to rapid flow waters, which comprises a bucket rod, a bucket body and a hydraulic cylinder, and further comprises a cross suspension device and an anti-floating device. The bucket body can slant a certain angle along the horizontal and longitudinal directions when the cross suspension device of the invention is acted with the effect of water flow impact or in the gyroscopic motion of loading and unloading mud, which avoids the bucket rod from bearing enormous bending moment, and reduces the fault rate on the joint portion of the bucket rod and the hydraulic grab bucket. And the anti-floating device can limit the slanting angle of the bucket body over large under the water flow impact, avoids the phenomenon of over-large bucket floating or horizontal bucket, and increases the working efficiency of digging.

Description

Be applicable to the underwater hydraulic grab bucket in torrent waters
Technical field
The present invention relates to a kind of hydraulic grab of using under water, particularly a kind of underwater hydraulic grab bucket that is applicable to the torrent waters.
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.If adopt the structure that grab bucket can be rotated on water (flow) direction, the upstream face of grab bucket is subjected to water impact, because the weight capacity ratio of hydraulic grab is lower, the grab bucket certain angle that drifts about downstream, flow velocity is big more, and it is big more to float the bucket angle, when flow velocity surpasses 3m/s even the bucket phenomenon that occurs crouching, causing grabbing bucket, two lamellar bodies can't equity carries out closure by normal parabolic path and excavate, thereby fills little, the empty bucket rate of the coefficient height that struggles against, and work efficiency is low.
Therefore, need improve to hydraulic grab and with the connected mode of dipper, in that bucket body can be at the both direction certain angle that tilts 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; Simultaneously, it is excessive to limit the angle of inclination again, avoids bucket bucket phenomenon excessive or for sleeping in occurring floating, improves and excavates work efficiency.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of underwater hydraulic grab bucket that is applicable to the torrent waters, in that bucket body can be at the both direction certain angle that tilts 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 is connected part with hydraulic grab fault rate, simultaneously, it is excessive to limit the angle of inclination again, avoid bucket bucket phenomenon excessive or for sleeping in occurring floating, improve and excavate work efficiency.
The underwater hydraulic grab bucket that is applicable to the torrent waters of the present invention comprises dipper, bucket body and hydraulic cylinder, also comprises cross suspension arrangement and anti-waving apparatus; The cross suspension arrangement comprises connecting rod, the connecting rod upper end is provided with the dipper connecting hole, 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, connecting rod with can freely swing with respect to the dipper Parallel to the flow direction after dipper is connected, bucket body with can freely swing perpendicular to water (flow) direction with respect to connecting rod after connecting rod is connected; Anti-waving apparatus comprises being fixedly installed on grabs bucket the bar upper limit position block and is fixedly installed on the connecting rod lower position block, described upper limit position block and lower position block are separately positioned on dipper and connecting rod water (flow) direction one side dorsad, the lower surface of upper limit position block is relative with the lower position block upper surface, the lower surface of upper limit position block and lower position block upper surface near the time, the angle that the grab bucket Parallel to the flow direction rotates is 15 °-20 °.
Further, described connecting rod is Word shape, the grab bucket connecting hole runs through Word shape bottom bipod, the dipper connecting hole is arranged at The word shape upper end;
Further, the circle two ends are provided with anti-wearing liner in the described dipper connecting hole;
Further, described upper limit position block and the lower position block mode that fixedly installs on dipper and connecting rod is welding;
Further, the lower surface of described upper limit position block and lower position block upper surface near the time, the angle that the bucket body Parallel to the flow direction rotates is 18 °.
The invention has the beneficial effects as follows: the underwater hydraulic grab bucket that is applicable to the torrent waters of the present invention, adopt the cross setting between dipper connecting hole on the connecting rod and the grab bucket connecting hole, and be provided with anti-waving apparatus, during use, dipper connecting hole and dipper, the grab bucket connecting hole with the grab bucket between the employing hinge be connected, can be at bucket body under the impact force of water flow effect or in the gyration process of loading and unloading mud at the certain angle that tilts of both direction in length and breadth, avoid dipper to bear huge moment of flexure, reduce dipper and be connected fault rate partly with hydraulic grab, it is excessive in the water impact angle that has a down dip that anti-waving apparatus can limit bucket body again, avoid bucket bucket phenomenon excessive or for sleeping in occurring floating, improve and excavate work efficiency; Connecting rod is Word shape makes linkage simple and compact for structure, saves manufactured materials; In the dipper connecting hole anti-wearing liner is set, effectively protects connecting rod and application life of improving connecting rod, the wearing and tearing back only needs to change anti-wearing liner, reduces use cost; Means for preventing driftage adopts the connected mode of welding, makes total simple, and the intensity height is durable in use.
