Abstract
The utility model relates to a stone-resistant ring of a suction dredge reamer mud-sucking mouth, which belong to the technical field of dredging engineering. The utility model is characterized in that the stone-resistant ring whose diameter is suitable to the center line of a reamer shaft and the mud-sucking mouth is a steel ring structure; the stone-resistant ring is disposed at a position of the average diameter of the mud-sucking mouth; the stone-resistant ring is welded to a reamer wheel hub and a reamer arm and is integrated with the reamer into one piece. The utility model is advantageous in that the structure is simple; the producing and adjusting are convenient; the cost is low and the influence on work efficiency is small; time of cleaning big stones can be saved for a suction dredge; the rate of a dredge pump being damaged by a large stone can be reduced; the time utilization rate of a ship can be improved.
Description
Technical field
The utility model belongs to the dredging works technical field, particularly relates to a kind of cutter suction dredger reamer and inhales the anti-stone ring of mud mouth.
Background technology
At present, along with international carriage cause and harbor approach are built fast development, dredging industry and construction equipment thereof, construction operating mode face the challenge, dig many influence factors such as dark, haul distance, oil consumption cost and show especially gradually, wherein more and more harder, complicated soil property situation is the most direct, a conspicuous sensible factor in the construction.
When in excavating decomposed rock or dredging weak soil matter, containing piece stone as the existing reamer of the cutter suction dredger of dredging main force's ship type, piece stone enters dredge pump during excavation, the impact force that produces is destroyed the pump courage easily, and the part stone also can be stuck in and make the machine can not balance work in the impeller, damages power transmission shaft.Reduced the time availability of boats and ships the maintenance time that this can increase ship dredging construction, increased construction cost.
Existing solution strand is inhaled the method for this problem of ship and had following subject matter: 1. inhaling the mud mouth increases barrier; Increase the parallel reinforcing bar of some between 2. adjacent tool arm.This method is tackled the above stone of dredge pump latus rectum, and the barrier and the rebar spacing that need to be provided with will be close with latus rectum, causes workload relatively big and to the production efficiency obvious effect, it is also cumbersome to want to adjust spacing according to operating mode.
Summary of the invention
The utility model provides a kind of cutter suction dredger reamer to inhale the anti-stone ring of mud mouth for solving the problem that prior art exists.
The utility model purpose provide a kind of have simple in structure, making and easy to adjust, cost is low, simple in structure, and it is less to the productivity ratio influence, can save the time of cleaning ratchel for the cutter suction dredger construction, reduce the probability that dredge pump damages because of ratchel, improve the cutter suction dredger reamer of the characteristics such as time availability of boats and ships and inhale the anti-stone ring of mud mouth.
The utility model cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth and is adopted following technical scheme:
A kind of cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth, be characterized in: anti-stone ring is the steel loop structure, the center line of diameter and reamer macro-axis and suction mud mouth adapts, and anti-stone ring is positioned at inhales mud mouth average diameter position, and anti-stone ring is welded on reamer wheel hub and the reamer arm and connects to an integral body with reamer.
The utility model cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth can also adopt following technical measures:
Described cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth, and be characterized in: anti-stone ring is the steel loop that plate is made, and steel plate thickness is 25-35mm, and width is 10-40cm.
Described cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth, is characterized in: anti-stone ring is 2-20cm apart from the distance of inhaling mud mouth marginal point.
Described cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth, is characterized in: anti-stone ring axis is identical with the reamer axis.
Advantage that the utlity model has and good effect:
The cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth, owing to adopted the utility model brand-new technology scheme, compared with prior art, the utility model is more simple in structure than conventional method, making and easy to adjust, and it is low to have cost, simple in structure, advantage such as make and easy to adjust, and less to the productivity ratio influence, can be the time that the cleaning ratchel is saved in the cutter suction dredger construction, reduce the probability that dredge pump damages because of ratchel, improve the time availability of boats and ships.
Description of drawings
Fig. 1 is the anti-stone ring three-dimensional structure schematic diagram of the utility model;
Fig. 2 inhales the mud mouth to bow to structural representation.
Among the figure, 1-reamer wheel hub, 2-cutter piece, 3-reamer tooth, 4-reamer ring, the anti-stone ring of 5-, 6-securing bracket, 7-mangler shaft, 8-inhale the mud mouth, 9-inhales mud mouth center line.
The specific embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and be described with reference to the accompanying drawings as follows:
With reference to accompanying drawing 1 and Fig. 2.
A kind of cutter suction dredger reamer is inhaled the anti-stone ring of mud mouth, be the steel loop structure, the center line of diameter and reamer macro-axis and suction mud mouth 4 adapts, and anti-stone ring is positioned at inhales mud mouth 4 average diameter positions, and anti-stone ring 5 is welded on reamer wheel hub 1 and the reamer arm and connects to an integral body with reamer.Reamer tooth 3 is arranged on the cutter piece 2.Securing bracket 6 is equipped with at anti-stone ring 5 places.
The steel loop that anti-stone ring is made for the air hardening steel plate, steel plate thickness are 25-35mm, and width is 10-40cm.Anti-stone ring is 2-20cm apart from the distance of inhaling mud mouth marginal point.Anti-stone ring axis is identical with the reamer axis.
The concrete structure of present embodiment and installing and using:
The anti-stone ring of reamer will pull out near the boulder of suction inlet along with reamer rotates, and prevents that stone from entering dredge pump, destroys the pump courage; Prevent that ratchel is stuck in impeller and produces stifled pump phenomenon, avoid the machine can not balance work, the situation of destroying power transmission shaft takes place.
The technical conceive of present embodiment is: adopt certain thickness steel loop to be made, diameter will and be inhaled mud mouth center line 9 with mangler shaft 7 and adapt, and the steel loop placement location is near suction mud mouth 8 average diameters.
Manufacturing process: at first measure the size of dredging pump impeller runner, to determine anti-stone ring steel plate thickness and diameter, form the circulus that links the reamer wheel hub, the making of anti-stone ring finishes.
The present embodiment strand is inhaled the anti-stone ring characteristics of ship:, making and easy to adjust more simple in structure than conventional method.
