The device is characterized in that the front end of a breaking hammer is provided with cooling nozzles, and the cooling nozzles comprise a jet nozzle and / or an atomization nozzle; before the breaking hammer is used for rock breaking, and the device for cooling and dust suppression is connected with a high-pressure water resource; when the breaking hammer strikes the broken rock, the jet nozzle and the atomization nozzle operate independently or synchronously; the jet nozzle forms a jet flow, and the jet flow converges on the head of the drill rod, thereby realizing rapidly cooling the head of the drill rod when the breaking hammer breaks hard rock; and the atomization nozzle forms mist which surrounds the drill rod, and the dust is separated by the mist, thereby restraining the rock dust. The device and method provided by the invention have the advantages of solving the problem of dust generated during a construction process, realizing the real-time cooling of the drill rod during a rock breaking process based on the breaking hammer, thereby maintaining the good strength and hardness of the drill rod, prolonging the service life of the drill rod, and further realizing the control and elimination of the dust during the rock breaking process, thereby reducing the harm caused by the dust to the working environment and operation staff from the roots.
Description
Technical field
The present invention relates to the dedusting field of crushing hammar drill rod, be specially a kind of cooling dust-arrest device and method of crushing hammar drill rod.
Background technology
Pneumatic or hydraulic breaking hammer back and forth clashes into drilling tool by driving block stamp (piston), makes impact force that drilling tool produces act on bore bit (drill steel head) with the form of stress wave, finally makes bore bit fractured rock, concrete etc. efficiently.At present, hydraulic breaking hammer just develops towards directions such as form of structure variation, product seriation, intellectuality and super large ballistic works.The maximum impact merit of hydraulic breaking hammer reaches more than the 15000J at present.
Just because of the HI high impact merit and the HI high impact frequency of hydraulic breaking hammer, working environment such as they have been widely used in and have built the road, building demolition, underwater operation, quarrying, mining and construction of tunnel.In above-mentioned work progress, drill steel is done the time spent with rock can produce a large amount of heats and dust.If can not in time cool off the drill steel head, drill steel head thermal accumlation will produce the effect of tempering, reduces the hardness and the intensity of drill steel head, and then reduces the application life of drill steel.If can not effectively eliminate the dust that work progress produces, dust will worsen construction environment, influences operating personnel's sight line, and damages for operating personnel's health.
Summary of the invention
In order to overcome quartering hammer use above shortcomings, improve the application life of drill steel, improve operating personnel's working environment, the invention provides a kind of cooling dust-arrest device and method of crushing hammar drill rod, solve the problems such as dust that work progress produces.Adopt the present invention, can realize the real-time cooling of the broken rock process drill steel of quartering hammer, thereby keep the good strength and the hardness of drill steel, increase the application life of drill steel, more can realize brokenly the inhibition and the elimination of rock process dust, reduce the injury of dust operating environment and operating personnel's body and mind from root.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cooling dust-arrest device of crushing hammar drill rod, this device is for being provided with cooling jet at the front end of quartering hammer, and cooling jet is divided into jet nozzle and pulverizing nozzle, uses wherein one or both as required.
The cooling dust-arrest device of described crushing hammar drill rod, cooling jet is installed in the front end of quartering hammer clamping plate or shell.
The cooling dust-arrest device of described crushing hammar drill rod, the setting angle of jet nozzle, assurance converges in the drill steel head of quartering hammer front end from the jet of jet nozzle ejection.
A kind of cooling dust-suppression method of crushing hammar drill rod is by being provided with jet nozzle and/or pulverizing nozzle is realized on quartering hammer; Before the broken rock of quartering hammer, will cool off dust-arrest device and link to each other with high-pressure water; During quartering hammer impact cutting rock, the independent or synchronous working of jet nozzle and pulverizing nozzle; Jet nozzle forms jet, and jet converges in the drill steel head, and the drill steel head cools off fast when realizing quartering hammer fragmentation hard rock; The water smoke that pulverizing nozzle forms is centered around around the drill steel, isolates dust by water smoke, suppresses rock dirt.
The invention has the beneficial effects as follows:
1, the present invention is provided with cooling jet at the front end of quartering hammer clamping plate or shell.Nozzle has two kinds, and a kind of is pulverizing nozzle, is used for isolating and suppress the dust that the broken rock process of quartering hammer produces at the peripheral water smoke layer that forms of drill steel; Another kind is a jet nozzle, and the jet of nozzle ejection converges in the drill steel head, is used for taking away brokenly rapidly the heat that produces between rock process drill steel head and rock, keeps the intensity of broken rock process drill steel and the stability of hardness.
2, the present invention can increase the application life of drill steel significantly, improves operating personnel's working environment greatly, reduces to minimum to the injury of operating personnel's body and mind dust.
Description of drawings
Fig. 1 is a crushing hammar drill rod cooling dust-arrest device schematic diagram of the present invention;
Among the figure, 1 quartering hammer; 2 jet nozzles; 3 pulverizing nozzles; 4 drill steels; 5 jets; 6 water smokes.
The specific embodiment
As shown in Figure 1, the front end of quartering hammer 1 is installed drill steel 4, and crushing hammar drill rod cooling dust-arrest device of the present invention is provided with cooling jet for the front end at quartering hammer 1.
Among the present invention, the type of cooling jet is divided into jet nozzle 2 and pulverizing nozzle 3, can use wherein one or both as required; Nozzle quantity can be provided with flexibly according to quartering hammer model and actual the requirement.
Among the present invention, cooling jet is installed in the front end of quartering hammer clamping plate or shell, in the middle of pulverizing nozzle 3 is positioned at, around jet nozzle 2 is positioned at.
The cooling dust-suppression method of crushing hammar drill rod of the present invention, it is by being provided with jet nozzle 2 and/or pulverizing nozzle 3 is realized on quartering hammer clamping plate or shell.The high-pressure spray of jet nozzle 2 ejection converges to the drill steel head, and drill steel 4 heads cool off fast in the time of can realizing the broken hard rock of quartering hammer 1, to keep the intensity and the hardness of drill steel.The water smoke of pulverizing nozzle 3 ejections is isolated dust round drill steel 4 by water smoke, realizes suppressing the purpose of rock dirt.
Among the present invention, the setting angle of jet nozzle 2 should guarantee that the high-pressure spray that sprays converges near the drill steel head.
Before the quartering hammer 1 broken rock, the cooling dust-arrest device be linked to each other with high-pressure water, and regulate pressure and flow.During quartering hammer 1 impact cutting rock, jet nozzle 2 and pulverizing nozzle 3 independent or synchronous workings.The jet 5 that jet nozzle 2 forms as shown in Figure 1, jet 5 converges in drill steel 4 ends, and the water smoke 6 that pulverizing nozzle 3 forms is as shown in Figure 1, is centered around around the drill steel.
When quartering hammer stopped to impact, pulverizing nozzle and jet nozzle also quit work (or delaying time a little several seconds), flow to behind the construction area ground influence that equipment moving and personnel's action are caused to reduce the jet atomization current.
