Abstract
The invention provides a drill rod positioning device for drilling an underwater rockplug blasting presplitting hole. The device is characterized in that a semicircular positioning steel pipe, a front connecting reinforcing steel bar, a medium connecting reinforcing steel bar, a rear connecting reinforcing steel bar and a lower supporting steel plate are welded to form an integral bevel framework, wherein the front connecting reinforcing steel bar, the medium connecting reinforcing steel bar and the rear connecting reinforcing steel bar are of different height from low to high and are respectively welded to the left end, the medium end and the right end of the lower supporting steel plate; the semicircular positing steel pipe is welded to the upper ends of the three connecting reinforcing steel bars. The device is high in generality, can be preprocessed in a factory and then is conveniently mounted at the site; when in use, the device is positioned on the rock at the back of a presplitting hole to be drilled, the axis of the semicircular positioning steel pipe and the center line of the presplitting hole are kept in a straight line and fixed, and a drill rod of a drilling machine is positioned on the semicircular positioning steel pipe for drilling. The device is simple and convenient to mount and dismount, fast to construct, capable of being recycled at a plurality of times, uneasy to be damaged, cost saving, and high in drilling precision, and the drilling quality is greatly improved.
Description
Technical field
Device used when the present invention relates to a kind of presplitting hole drilling of chock blasting under water, when particularly relating to a kind of presplitting hole drilling for underwater rock plug burst, for meeting the precision of presplitting hole drilling, needs the drilling rod of rig to carry out pinpoint device.
Background technology
Hydroelectric project is when carrying out underwater rock plug burst construction, and in order to ensure that the Forming Quality of rock plug mouth reaches designing requirement, when explosion designs, be usually furnished with some pre-ceasmas in all design sidelines, edge of rock plug, the borehole accuracy of this pre-ceasma often requires higher.General Normal practice is after being put by rig and putting in place, adopts measuring apparatus observation, progressively adjusts, then is fixed on by rig on the scaffold set up in advance.In the whole adjustment fixation procedure of rig, measuring apparatus needs to observe all the time, and the time is long, and construction comparatively bothers, and inconvenient operation, and positioning precision is not high.
Summary of the invention
In order to solve the problem, the invention provides a kind of simple to operate, easy to use, can reuse, when effectively solving underwater rock plug burst construction, the drill pipe positioner of the presplitting hole drilling of borehole accuracy can be guaranteed.
The taked technical measures that solve the problem are:
A kind of drill pipe positioner for underwater rock plug burst presplitting hole drilling, it is characterized in that: by semicircle positioning steel tube 1, the anterior connecting reinforcement 2 highly do not waited from low to high, middle part connecting reinforcement 3 and rear portion connecting reinforcement 4 and lower support steel plate 5 are welded into the overall skeleton in inclined-plane, wherein: anterior connecting reinforcement 2 is welded on the left end of lower support steel plate 5, middle part connecting reinforcement 3 is welded on the middle-end of lower support steel plate 5, rear portion connecting reinforcement 4 is welded on the right-hand member of lower support steel plate 5, semicircle positioning steel tube 1 is welded on anterior connecting reinforcement 2, the upper end of middle part connecting reinforcement 3 and rear portion connecting reinforcement 4.
beneficial effect of the present invention: compatibility of the present invention is good, in advance after processing factory processes, can carry out in-site installation easily.During construction, this device is placed on the pre-ceasma rear portion scar of needs boring, through surveying setting-out, make the center line of the axis of the semicircle positioning steel tube 1 of this device and pre-ceasma point-blank, fix with expansion bolt or anchor pole, then the drilling rod of rig is shelved on above semicircle positioning steel tube 1, boring can be started.This device not only installation and removal is simple, convenient, and speed of application is fast, and repeatedly can have enough to meet the need use, not fragile, cost-saving, the precision utilizing this device to carry out holing is high, thus improves the quality of boring.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is specifically described.
A kind of drill pipe positioner for underwater rock plug burst presplitting hole drilling, utilize shaped steel to weld to combine, as shown in Figures 1 to 4, by semicircle positioning steel tube 1, the anterior connecting reinforcement 2 highly do not waited from low to high, middle part connecting reinforcement 3 and rear portion connecting reinforcement 4 and lower support steel plate 5 are welded into the overall skeleton in inclined-plane, wherein: anterior connecting reinforcement 2 is welded on the left end of lower support steel plate 5, middle part connecting reinforcement 3 is welded on the middle-end of lower support steel plate 5, rear portion connecting reinforcement 4 is welded on the right-hand member of lower support steel plate 5, semicircle positioning steel tube 1 is welded on anterior connecting reinforcement 2, the upper end of middle part connecting reinforcement 3 and rear portion connecting reinforcement 4.
In the present invention, semicircle positioning steel tube 1 adopts that length is 500mm, diameter is 50mm, thickness is the steel pipe of 3mm, and longitudinally cut open into identical two halves from any diameter of steel pipe along steel pipe, every semi-steel pipe is a semicircle positioning steel tube 1; Anterior connecting reinforcement 2, middle part connecting reinforcement 3 and rear portion connecting reinforcement 4 all adopt diameter to be that II grade of indented bars of 22mm processes.Lower support steel plate 5 adopts that thickness is 10mm, width is 30mm, length is the steel plate of 300mm.After being welded into overall skeleton shown in Fig. 1, namely organize cost apparatus.Pinpoint object is reached for making this device, this apparatus design is become inclined plane shape, that is: by anterior connecting reinforcement 2, middle part connecting reinforcement 3 and rear portion connecting reinforcement 4 are designed to height not etc. from low to high, this is because pre-ceasma is angled with the scar of tunnel below, this device is placed on the pre-ceasma rear portion scar of needs boring, the axis needs of semicircle positioning steel tube 1 and the center line of the pre-ceasma that will hole are point-blank, like this, the drilling rod of rig is shelved on semicircle positioning steel tube 1 above after, the direction of boring could be consistent with the direction of intending boring pre-ceasma, play pinpoint effect.
During use, this device is placed on the pre-ceasma rear portion scar of needs boring, the particular location of this device is adjusted by surveying setting-out, the axis making the semicircle positioning steel tube 1 of this device and the center line of pre-ceasma that will hole are point-blank, then with expansion bolt or anchor pole by this device fixation, namely complete the installation of this device.During boring, the drilling rod of rig is shelved on above semicircle positioning steel tube 1, the boring of pre-ceasma can be started.
