Description
Technical field
The utility model relates to a kind of Counterboring apparatus, particularly relates to a kind of boring and coring Counterboring apparatus.
Background technology
In the quality examination of stone riprap sea wall, normal employing boring and coring method.In recent years along with sea wall constantly stretches out, the thickness of stone riprap constantly increases (maximum exceed 50m), has higher requirement to boring and coring equipment.One highest wisdom gets the core degree of depth comparatively greatly, then need to adopt large-scale geological sampling equipment, if construct on the island lacking net electricity, needing to be equipped with large-scale generating equipment provides power, and also need large lifting equipment to assist in construction, construction cost is higher.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of boring and coring Counterboring apparatus, realizes heavy thickness stone riprap get core in simple, fast mode.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of boring and coring Counterboring apparatus, impact bar one end is connected with coring drill rod threaded one end, the coring drill rod other end is connected with gravity drop hammer one end, gravity drop hammer one end is connected with hoist engine through fixed pulley by wire rope, and hoist engine is connected with small generator.
Described impact bar main body is manganese steel cylinder, is provided with silk thread mouth with impact bar link, and the other end conically.
Described gravity drop hammer has the endoporus of fixing coring drill rod termination.
The shaft of described coring drill rod and gravity drop hammer link has breach, and this breach matches with the projection on gravity drop hammer inner hole wall.
Described fixed pulley is fixed on tripod top.
A kind of boring and coring Counterboring apparatus that the utility model provides, by coordinating with small-sized rock-core borer, reducing and getting core thickness to the requirement of getting core equipment and power source, for heavy thickness core, only need to coordinate with small-sized rock-core borer, heavy thickness stone riprap can be realized and get core.The utility model structure is simple, and easy to install, input cost is low, and operating efficiency is high, can effectively take out qualified core.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is described further:
Fig. 1 is the utility model structural representation.
In Fig. 1: impact bar 1, coring drill rod 2, gravity drop hammer 3, wire rope 4, fixed pulley 5, hoist engine 6, tripod 7, small generator 8, stone riprap sea wall 9.
Detailed description of the invention
As shown in fig. 1, a kind of boring and coring Counterboring apparatus, impact bar 1 one end is connected with coring drill rod 2 threaded one end, and coring drill rod 2 other end is connected with gravity drop hammer 3 one end, gravity drop hammer 3 one end is connected with hoist engine 6 through fixed pulley 5 by wire rope 4, and hoist engine 6 is connected with small generator 8.
Structure thus, small generator 8 provides power for hoist engine 6, and hoist engine 6 realizes gravity drop hammer 3 by wire rope 4 through fixed pulley 5 and moves; Coordinated with small-sized rock-core borer by this device, the core work of heavy thickness stone riprap can be realized.
Described impact bar 1 main body is manganese steel cylinder, and be provided with silk thread mouth with impact bar 1 link, the other end conically.Impact bar 1 adopts the field fabrication of manganese round steel, and its length and diameter are considered to determine according to combined factors such as the diameter of boring and coring and the degree of depth.
Described gravity drop hammer 3 has the endoporus of fixing coring drill rod 2 termination.Gravity drop hammer 3 need at central aperture, and its aperture equals coring drill rod 2 external diameter, is fixed in gravity drop hammer 3 hole coring drill rod 2 upper end after perforate.
Described coring drill rod 2 has breach with the shaft of gravity drop hammer 3 link, and this breach matches with the projection on gravity drop hammer 3 inner hole wall.Breach on coring drill rod 2 matches with the projection on gravity drop hammer 3 inner hole wall can realize both being connected and fixed.
Described fixed pulley 5 is fixed on tripod 7 top.
Before site operation, first to carry out installation to the utility model device and connect.First set up tripod 7, hoist engine 6 and minitype diesel oil engine 8 are placed on around, install fixed pulley 5 on tripod 7 top, and wire rope 4 is through fixed pulley 4, and one end is connected with hoist engine 6, and one end is connected with gravity drop hammer 3 upper end in addition.Gravity drop hammer 3 lower end is connected with coring drill rod 2, and coring drill rod 2 lower end is connected with impact bar 1 top.
During site operation, first start to creep into small-sized rock-core borer installation large aperture (as 200mm diameter) core drilling tool and get core, first time creeps into and gets the core degree of depth and be about 2m, retaining wall conduit (diameter 186mm) is installed, then use small-bore (if diameter is 78mm) rock core drilling tool instead and carry out boring and coring, the degree of depth is about 3-5m, after taking out this part core, connect the utility model device, impact reaming is carried out to diameter 186mm to small-bore (diameter is 78mm) part, overlap core drilling tool (diameter 186mm) again and core is got to bottom, circulation like this, simultaneously according to power situation, drilling depth, reaming resistance, rockfill intermediate gap (according to the drill water situation) section of adjustment drilling depth and counter bore diameter, until the core degree of depth is got in design.
