Abstract
The utility model discloses a drilling tool with a rear-mounted member. The drilling tool comprises an electric hammer, wherein the electric hammer is fixed on the top of a vertical supporting rod, the bottom of the supporting rod is provided with a pressure rod and a connecting rod, which are hinged to the supporting rod, the pressure rod and the connecting rod are respectively connected with a supporting leg through a hinge, the supporting leg, the pressure rod, the connecting rod and the supporting rod form a parallelogram structure, and the pressure rod is provided with a pressing part stretching out of the outer side of the supporting leg. By adopting the drilling tool, a movable scaffold is avoided, the time is saved, and the working efficiency is improved. Meanwhile, the high-altitude construction can be avoided, and the safety risk can be reduced; simplicity in operation is realized, and the drilling tool is applicable to any floor height; the nearby contact with dust can be effectively avoided, the body health is favored, and the professional disease risk is reduced; by adopting the lever principle, the labor intensity of the operation worker can be greatly alleviated, and the professional health of the worker can be favored.
Description
Technical field
The utility model relates to a kind of instrument for holing, particularly a kind of boring bar tool that rearmounted part is installed.
Background technology
In recent years, along with the prosperity of real-estate market, the public buildings such as some restaurants, hotel, large supermarket, hospital, school, office building are more and more.These building communal space interior decoration forms are also the trend of development in pluralism, choose high space ceiling decoration, generally all will carry out ceiling construction, and relate to a large amount of rearmounted part installations.Built-in fitting is set when the structure construction, and secondary decoration all needs to carry out the fixing points such as keel and suspension rod and is connected with the effective of structure, and usual way is structural beams twist drill hole, rearmounted expand tube, then be connected by materials such as connector and keel, suspension rods.Because public building floor is relatively high, rearmounted part is installed comparatively loaded down with trivial details, needs the techniques such as snap the line, boring, installation, generally will set up jenny scaffold, and with story height difference, jenny scaffold scaffolding height may exceed 5 meters.Like this, have on the one hand larger potential safety hazard, workman can avoid because of upper and lower scaffold and movable Scaffold when operation on the other hand, and the loss of efficiency causing.In addition, stand in drilling construction above scaffold, can closely produce a large amount of dusts, to healthy, impact.
Utility model content
The utility model provides a kind of boring bar tool that rearmounted part is installed for solving the technical problem existing in known technology, and this tool construction is simple, easy to operate, can make workman carry out rapidly drilling construction, and safety is on healthy nothing impact.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of boring bar tool that rearmounted part is installed, comprise electric hammer, described electric hammer is fixed on the top of the pressure pin of vertical setting, in the bottom of described pressure pin, be provided with the depression bar hinged with it and connecting rod, described depression bar is connected with supporting leg by a hinge respectively with described connecting rod, between described supporting leg, described depression bar, described connecting rod and described pressure pin, form parallelogram sturcutre, described depression bar is provided with the press section of stretching out a described leg outer side.
Described depression bar is positioned at the below of described connecting rod.
The drill bit of described electric hammer is provided with drilling depth line.
Described hinge is formed by bolt, and described bolt is movably connected on described supporting leg.
Advantage and the good effect that the utlity model has are:
One) can avoid setting up jenny scaffold, save time, improve work efficiency.Meanwhile, can avoid eminence construction, reduce security risk.
Two) simple to operate, no matter floor height height is all applicable.
Three) can effectively avoid close contact dust, be conducive to healthyly, reduce occupational disease risk.
Four) by adopting lever principle, greatly reduce operator's labour intensity, be conducive to workman's occupational health.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, electric hammer; 2, pressure pin; 3, supporting leg; 4, connecting rod; 5, depression bar.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of boring bar tool that rearmounted part is installed, comprise electric hammer 1, described electric hammer 1 is fixed on the top of the pressure pin 2 of vertical setting, in the bottom of described pressure pin 2, be provided with the depression bar hinged with it 5 and connecting rod 4, described depression bar 5 is connected with supporting leg 3 by a hinge respectively with described connecting rod 4, between described supporting leg 3, described depression bar 5, described connecting rod 4 and described pressure pin 2, forms parallelogram sturcutre, and described depression bar 5 is provided with the press section of stretching out described supporting leg 3 outsides.
In the present embodiment, for handled easily, make described depression bar 5 be positioned at the below of described connecting rod 4.For the ease of the degree of depth of observation boring, on the drill bit of described electric hammer, be provided with drilling depth line.For convenient, make, described hinge adopts bolt to form, and described bolt is movably connected on described supporting leg 3.
Adopt the utility model to coordinate and can carry out drilling construction by the first and second two workmans.Boring concrete operation step is as follows:
The first,, according to design drawing requirement, at the bottom of plate, carry out unwrapping wire.Unwrapping wire adopts the PPR the being of convenient length pipe of a diameter 20mm, and upper end is cloth beyond the Great Wall, dips in the red paint after upper dilution with cloth, and at the bottom of plate, mark bores a some position.According to different situations, unit in charge of construction also can adopt other mark modes easily.
The second,, after unwrapping wire completes, start drilling construction.Arrange the first and second two workmans to carry out the operation of this instrument, first is responsible for the control of instrument, and second is responsible for the control of power supply.
Three, first first workman guarantees that supporting leg is perpendicular to ground, and lower moulded rod, makes to move on pressure pin by the parallelogram sturcutre forming between supporting leg, depression bar, connecting rod and pressure pin, drives the drill bit on electric hammer to aim at point to be bored.
Four, second workman switches on power, and owing to electric hammer switch being arranged on to normally open in advance, after energising, electric hammer starts boring.First workman continues downward moulded rod, keeps electric hammer to hole upward.
Five, after drilling depth is suitable, unclamp depression bar, make pressure pin drive electric hammer to fall after rise, second workman's deenergization.
Six, repeat above the 3rd to the 5th step, until complete all drilled hole task.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
