Abstract
The utility model relates to a high-pressure cutting drill bit comprising a drill bit body, a through hole of a stepped structure is formed in the middle of the drill bit body, two supports are arranged at the head of the through hole, an angle is formed between the two supports, a nozzle is installed on each support, and the end of each nozzle is pressed tightly through a gland and is fastened through bolts. The high-pressure cutting drill bit is reasonable in structure and convenient to manufacture and install, and the nozzles are easy to replace and reliable in installation.
Description
Technical field
The utility model relates to the engineering construction drilling tool, especially a kind of high pressure cutting bit.
Background technology
Drill bit is used for the cutting of super-pressure waterpower, and the water cutting is the diamond abrasive that is mixed with the certain granules granularity in water, and the water pressure that will be mixed with abrasive material with high-pressure hydraulic pump is loaded into 50Mp then, and water under high pressure comes out from current divider, ejects from drill bit through drilling rod.The water under high pressure that be mixed with abrasive material this moment has great speed, and diamond particles can carry out continuous grinding to being cut object under the drive of water under high pressure.Material to be cut cuts the most at last.
Because adamantine ablation, the nozzle in drill bit wearing and tearing itself are more serious, belong to consumable accessory, need often to change.The installation of bit nozzle of the prior art bothers with operation, and the active force of the water under high pressure that nozzle is suffered is bigger, and the installation reliability of nozzle is poor.
The utility model content
The applicant changes the shortcoming that bothers at bit nozzle in the above-mentioned existing production technology, a kind of high pressure cutting bit is provided, thereby has improved the connection reliability of bit nozzle, and it is convenient to change, and has improved stability, stressed more reasonable.
The technical scheme that the utility model adopts is as follows:
A kind of high pressure cutting bit comprises bit body, and described bit body middle part has the reach through hole of ladder-type structure, described reach through hole head is provided with two bearings of angulation, be separately installed with nozzle on the described bearing, the end of described nozzle compresses by gland, and passes through bolton respectively.
Its further technical scheme is:
Described nozzle adopts titanium alloy material;
Described gland is provided with the through hole corresponding with nozzle.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, makes with easy for installation, is easy to change nozzle, and it is reliably good that nozzle is installed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Wherein: 1, bolt; 2, gland; 3, through hole; 4, nozzle; 5, bearing; 6, bit body; 7, reach through hole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the high pressure cutting bit of present embodiment, comprise bit body 6, bit body 6 middle parts have the reach through hole 7 of ladder-type structure, reach through hole 7 heads are provided with two bearings 5 of angulation, are separately installed with nozzle 4 on (setting angle of nozzle 4 is decided according to the different application scenario of reality) bearing 5, and the end of nozzle 4 compresses by gland 2, gland 2 is provided with the through hole 3 corresponding with nozzle 4, and fastening by bolt 1 respectively.
Nozzle 4 adopts titanium alloy material, and it is high strength, and is corrosion-resistant, high-abrasive material.
The utility model forms gland 2 through the line cutting mode with bit body 6 one ends by a bar, when gland 2 was pressed on the nozzle 4, its axial direction was to move, and lateral can slide, namely adopt bolt 1 fastening, thus reliable fixed nozzle 4.Its overall structure good stability, axially lateral force is reasonable, has also avoided nozzle 4 axial floats that power is delivered on the bolt 1 simultaneously, influences the application life of bolt 1.
In the actual use, when nozzle 4 is worn when need changing, only need to shut down, pine is by bolt 1, and gland 2 slip pine on lateral leans on, and takes out nozzle 4, reloads new nozzle 4, gland 2 is being installed, and the bolt 1 of screwing on gets final product.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion within protection domain of the present utility model, can be done any type of modification referring to claim.
