Description

Drill rod detection equipment

Technical Field

The utility model relates to a building field especially relates to an equipment is visited to borer.

Background

The drill rod detection, also called light dynamic penetration test, is to detect the soil layer below the bottom surface of the foundation according to the regulations after the foundation excavation reaches the design elevation, judge the hardness of the soil, and detect whether a pit, an ancient tomb, an ancient well, an air-defense shelter, an underground buried object and the like exist. When the drill rod is detected, a heavy hammer with the mass of 10Kg is used for driving the steel drill rod into the soil, the drop hammer is 500mm high, the hammering number of each driving is recorded at 300mm, and the hardness of the soil can be judged according to the hammering number. The utility model of Chinese patent application No. 201420750571.2 discloses a drill rod pulling device for drill rod detection, which comprises a conduit, a bracket, a rotating shaft, a stress application rod and a mandril, wherein the bracket is fixedly arranged on the conduit; the rotating shaft penetrates through the stressing rod and is hinged with the bracket; the ejector rod is fixedly arranged at the front end of the stressing rod; the surface layer of the ejector rod is fixedly provided with a rubber layer. The lever principle is utilized to convert the left-right symmetrical upward applied external force part into two opposite forces to clamp the steel rod and pull up the steel rod. Although the auxiliary workpiece is more convenient to directly pull out the drill rod by hands, the auxiliary workpiece still needs labor.

Disclosure of Invention

An object of the utility model is to provide an equipment is visited to borer.

Realize the utility model discloses the technical scheme of purpose is: the utility model provides an equipment is visited to borer, its includes the drill rod body and pulls out borer mechanism, it includes a locating plate and crow bar to pull out borer mechanism, a through-hole has been seted up at the locating plate middle part, the diameter of through-hole slightly is greater than the diameter of the pole body of drill rod body, has seted up a bar locating hole in any side of through-hole on the locating plate, the arbitrary one end fixed mounting of crow bar has a locating shaft, and the one end movable sleeve that the locating shaft deviates from the crow bar is equipped with a buckle, the length of buckle is not more than the length of bar locating hole and is greater than the width of bar locating hole, the interval between locating.

The one end welding that the location axle deviates from the crow bar has a pivot, outside the pivot was located to the buckle cover, the axle head that the pivot stretches out the buckle was equipped with one soon and is used for the spacing nut to the buckle, nut and buckle clearance fit realize the swing joint of buckle and location axle from this.

The utility model discloses equipment is visited to borer for the locating plate of pulling out the borer constitutes detachable lever structure with the crow bar, its simple structure easily makes and installs, and the foot is stepped on the crow bar during use and can easily the drill rod body prize, has improved greatly and has pulled out borer efficiency.

fig. 3 is a schematic view of the installation structure of the positioning shaft and the buckle according to the embodiment of the present invention.

Detailed Description

The following description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, a drill detecting device comprises a drill body 1 and a drill pulling mechanism 2, wherein the drill pulling mechanism 2 comprises a positioning plate 21 and a pry bar 22, a through hole 211 is formed in the middle of the positioning plate 21, the diameter of the through hole 211 is slightly larger than that of a rod body 11 of the drill body, and a strip-shaped positioning hole 212 is formed in the positioning plate 21 on either side of the through hole 211; arbitrary one end fixed mounting of crow bar 22 has a locating shaft 23, the one end 231 welding that locating shaft 23 deviates from the crow bar has a pivot 24, and outside pivot 24 was located to a buckle 25 cover, pivot 24 stretched out the axle head of buckle 25 and was equipped with one soon and be used for 25 spacing nuts 26 to the buckle,

nut

26 and 25 upper surface clearance fit of buckle, the length A of buckle 25 is not more than the length B of bar locating hole 212 and is greater than the width C of bar locating hole 212, interval D between locating shaft 23 and the buckle 25 bottom slightly is greater than locating plate thickness H.

When in drill rod detection, the bottom of the rod body of the drill rod body firstly passes through the positioning plate through the through hole of the positioning plate, then the rod body of the drill rod body is manually knocked to knock the rod body into the soil for drill rod detection operation, and the positioning plate cannot interfere with knocking operation because the diameter of the through hole is slightly larger than that of the rod body of the drill rod body; when pulling out the borer, put the locating plate in good order earlier, then pass the bar locating hole on the locating plate with the location axle on the crow bar, the epaxial buckle of rotational positioning makes the buckle perpendicular with the long limit of bar locating hole afterwards, accomplish the equipment of crow bar and locating plate from this, then with the visible stone everywhere on the building site, billet etc. fills up under the crow bar as cushion 100, pedal crow bar deviates from the tip of location axle, utilize lever principle to make locating plate one end perk, because the diameter of the through-hole of locating plate slightly is greater than the diameter of the pole body of drill rod body, then the pole body can be blocked after the locating plate perk, and the crow bar is trampled many times afterwards easily to pry.

The positioning plate of the utility model is usually made of iron plate or other conventional materials with certain hardness; the movable sleeving and fixing mode of the buckle and the positioning shaft is not limited to the embodiment, and the movable sleeving and fixing mode can also be a conventional sleeving and fixing structure in other mechanical fields as long as the buckle can be rotated and moved without departing from the positioning shaft; the positioning shaft and the crowbar as well as the positioning shaft and the rotating shaft can be welded and fixed.

The above only be the embodiment of the utility model discloses a not consequently restriction the patent scope of the utility model, all utilize the equivalent flow transform that the content of the specification was made, or direct or indirect application is in other relevant technical field, all including on the same reason the utility model discloses a patent protection within range.
