Abstract
The utility model relates to a removing device of drag head grid blockages, and belongs to the technical field of dredging engineering. The removing device of the drag head grid blockages is characterized by being of a steel frame structure, and protrusions for removing the blockages are installed on the steel frame fixed to a drag head and correspond to grid holes in a movable cover of the drag head. The removing device of the drag head grid blockages has the advantages of being simple in structure, convenient to assemble and disassemble, easy and convenient to operate, high in practicability, low in cost and the like, solves the problem that grids of a drag suction dredger are blocked by clay and sundries, can be widely applied to removing clays and sundries blocking a drag for dredge construction, and largely improves construction efficiency.
Description
Technical field
The utility model belongs to Dredging Technology field, particularly relates to a kind of scavenge unit of drag head grid obstruction.
Background technology
At present, drag suction dredger can run into various soil property operating modes in work progress, for preventing that foreign material from entering dredging tube road and stopping up dredge pump, drag head generally can be installed grid, traditional grid form is generally hard grid, the rigid structures being welded by steel plate or round steel, the probability that grid stops up is large, can greatly reduce the production efficiency of rake suction ship, once and stop up, there is not easy-clear, take time and effort, the continuity that can not keep construction, has reduced time availability, brings the practice of construction problems such as certain economic loss.
Summary of the invention
The utility model provides a kind of scavenge unit of drag head grid obstruction for solving the technical problem existing in known technology.
The purpose of this utility model is to provide a kind of scavenge unit of the drag head grid obstruction with the feature such as simple in structure, installation and removal are convenient, easy and simple to handle, practical, cost is lower.
The utility model is removed the design of clay, the stifled grid of foreign material: drag head grid is installed on movable guard, can constantly rotate with the change of movable guard angle, this drag head new structure member is installed on drag head body, when movable guard angle upwarps certain angle, this steel component contacts with clay or foreign material that grid place is stopped up, under the pulling force of movable guard hydraulic cylinder, this steel component can keep off the clay on grid or foreign material.
The utility model member is formed by round steel and reinforcement welded steel plate, adopt mode and the drag head body of bolt or welding to be rigidly connected, the reinforcement steel plate shapes of the structure of member, size, bottom etc. are determined by installation site, the angle of body in the form of structure of drag head grid and rake chamber, have sufficient intensity, grid is arranged on drag head movable guard.
The technical scheme that the scavenge unit of the utility model drag head grid obstruction is taked is:
A scavenge unit for drag head grid obstruction, is characterized in: scavenge unit is steel frame construction, be fixed on the steelframe of drag head obstruction removing projection be housed, obstruction remove with projection be installed on drag head movable guard on the hole of grid corresponding.
The scavenge unit of the utility model drag head grid obstruction can also adopt following technical scheme:
The scavenge unit of described drag head grid obstruction, is characterized in: steelframe is welded by round steel, steelframe bottom welding has reinforcement steel plate.
The scavenge unit of described drag head grid obstruction, is characterized in: obstruction removing is round steel head by projection, and round steel head is welded on steelframe.
The scavenge unit of described drag head grid obstruction, is characterized in: round steel head is corresponding to a hole of grid on drag head movable guard.
The scavenge unit of described drag head grid obstruction, is characterized in: steelframe adopts bolt or the welding manner drag head body that is rigidly connected.
Advantage and the good effect that the utlity model has are:
The scavenge unit of drag head grid obstruction is owing to having adopted the technical scheme that the utility model is brand-new, compared with prior art, the utility model is simple in structure, installation and removal are convenient, the method of the stifled grid of more traditional solution, there is the advantages such as easy and simple to handle, practical, cost is lower, solved rake and inhaled the technical problem that can not construct continuously that ship causes because of clay, the stifled grid of foreign material.For the operating mode of frequent stifled grid, stifled rake, the utility model has good promotion prospect, can greatly improve efficiency of construction.

Detailed description of the invention
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
The scavenge unit of drag head grid obstruction is a steel frame construction, is fixed on obstruction is housed on the steelframe 2 of drag head 5 removes with 3, the round steel of projection, and 3, round steel is welded on steelframe 2, round steel 3 head protrusions be installed on drag head movable guard on the hole of grid 1 corresponding.Round steel head is corresponding to a hole of grid on drag head movable guard.
The concrete structure of the present embodiment and the course of work:
The utility model is removed the drag head member of clay, the stifled grid of foreign material, is formed by round steel and reinforcement welded steel plate, adopts mode and the drag head body of bolt or welding to be rigidly connected, and has sufficient intensity.In the installation of drag head grid and movable guard.The present embodiment member adopts round steel to be welded, and is together welded in rake chamber with front and back reinforcement steel plate, and when drag head movable guard angle is lifted to maximum, as Fig. 9,10,11, the front end of new type of component top and the bottom can eject respectively grid 20cm, 10cm.
Practical application: certain engineering soil property is clay, and be mixed with a large amount of stones, for preventing that stone from entering dredging tube road and dredge pump, on drag head movable guard, grid is installed, because stone and clay frequent jams grid cause stifled rake, and general cleaning drag head measure produces little effect, the drag head labor cleaning above deck that need to hoist, waste plenty of time and manpower.At drag head body, this new type of component is installed, only drag head movable guard need to be raised to certain angle and just can complete the cleaning work of grid, therefore can accomplish the efficiently cleaning at any time in seabed of drag head grid, greatly reduce the manpower and the time that consume because clearing up drag head on deck, improved effective rate of utilization and the productivity effect of time.That the present embodiment has is simple in structure, installation and removal are convenient, easy and simple to handle, practical, cost is lower, can effectively remove the good effect such as clay, foreign material that stops up grid.
