Abstract
The eccentric chock locator of deadweight type, it relates to technical field of geological exploration, single action guard shield is set in the outer wall of inner core, basket is arranged on the outer wall of single action guard shield, be provided with packing ring between upper fulcrum guard shield and inner core, eccentric block is arranged on the side of inner core, and lower fulcrum guard shield is arranged on the outer wall of inner core, the end of inner core is provided with lower contact, and horseshoe tube is socketed in the outer wall of lower contact.The utility model accurate positioning, easy to operate, time saving and energy saving, economic benefit is obvious, especially more large more obvious for hole deviation.
Description
Technical field:
The utility model relates to technical field of geological exploration, is specifically related to the eccentric chock locator of a kind of deadweight type.
Background technology:
" geological prospecting " is namely reconnoitred geology by various means, method, detected, and determines suitable bearing stratum, according to the bearing capacity of foundation soil of bearing stratum, determines type of foundation, calculates the enquiry-based activity of underlying parameter.It is the mineral deposit finding that there is industrial significance in search for mineral deposit, for finding out the quality and quantity of mineral products, and the technical condition that exploitation utilizes, ore reserve required for mine construction designing and geologic information are provided, enquiry based work is carried out to geological conditions such as the rock in a given area, stratum, structure, mineral products, the hydrology, landforms.
Due to the precision of the inclination angle of the rock stratum of underground, lithology, rock, the change of interbedding of soft and hard rocks, artificial operation factors, equipment, technical factor etc. reason, often hole deviation is caused during construction, thus depart from former design axis, and then impact construction final purpose and construction effect are even holed and scrapped, hole deviation often causes to be scrapped and can not meet the requirement of construction object, and a usual cost hundreds of thousands of boring is to millions of, boring is once be given up, and cost is very expensive.
Utility model content:
The purpose of this utility model is to provide the eccentric chock locator of a kind of deadweight type, its accurate positioning, easy to operate, time saving and energy saving, and economic benefit is obvious, especially more large more obvious for hole deviation.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises basket, single action guard shield, inner core, upper fulcrum guard shield, eccentric block, lower fulcrum guard shield, lower contact, horseshoe tube, packing ring; Single action guard shield is set in the outer wall of inner core, and basket is arranged on the outer wall of single action guard shield, is provided with packing ring between upper fulcrum guard shield and inner core, eccentric block is arranged on the side of inner core, lower fulcrum guard shield is arranged on the outer wall of inner core, and the end of inner core is provided with lower contact, and horseshoe tube is socketed in the outer wall of lower contact.
In the utility model, upper fulcrum protective cover is connected with drilling rod; lower fulcrum protective cover is connected with horseshoe tube; horseshoe tube and eccentric block are riveted; deadweight type eccentric block is laid in the middle of two fulcrums; can rotate freely under Gravitative Loads; not by the control that drilling tool connects; and eccentric block is below connected to horseshoe tube and eccentric chock rotates together; eccentric block always direction vertically downward can be determined; according to the angle requirement that the bore angle of surveying in hole and actual needs are rectified a deviation; determine the connection angle of horseshoe tube and eccentric block, so determine eccentric chock lay angle.
The utility model accurate positioning, easy to operate, time saving and energy saving, economic benefit is obvious, especially more large more obvious for hole deviation.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention by the following technical solutions: it comprises basket 1, single action guard shield 2, inner core 3, upper fulcrum guard shield 4, eccentric block 5, lower fulcrum guard shield 6, lower contact 7, horseshoe tube 8, packing ring 9; Single action guard shield 2 is set in the outer wall of inner core 3, basket 1 is arranged on the outer wall of single action guard shield 2, packing ring 9 is provided with between upper fulcrum guard shield 4 and inner core 3, eccentric block 5 is arranged on the side of inner core 3, lower fulcrum guard shield 6 is arranged on the outer wall of inner core 3, the end of inner core 3 is provided with lower contact 7, and horseshoe tube 8 is socketed in the outer wall of lower contact 7.
In this detailed description of the invention, upper fulcrum protective cover is connected with drilling rod; lower fulcrum protective cover is connected with horseshoe tube; horseshoe tube and eccentric block are riveted; deadweight type eccentric block is laid in the middle of two fulcrums; can rotate freely under Gravitative Loads; not by the control that drilling tool connects; and eccentric block is below connected to horseshoe tube and eccentric chock rotates together; eccentric block always direction vertically downward can be determined; according to the angle requirement that the bore angle of surveying in hole and actual needs are rectified a deviation; determine the connection angle of horseshoe tube and eccentric block, so determine eccentric chock lay angle.
The accurate positioning of this detailed description of the invention, easy to operate, time saving and energy saving, economic benefit is obvious, especially more large more obvious for hole deviation.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
