Abstract

The utility model belongs to the field of geotechnical engineering geology, relates to a drilled core sampling device used for manufacturing a test piece for a mechanical test of a rock material, and particularly relates to an irregular rock mass drilled core sampling device for irregular rock mass. The device comprises a drilling machine, a drill bit, a bracket, a base, a connection plate, an end cover, a compaction plate, a sliding member and a pressing turntable, wherein the base of the device is a rectangular base formed by welding I-shaped steel cross beams; a sliding guide slot matched with the sliding member is formed in the base; the drilling machine, the drill bit and the pressing turntable are combined together and assembled on the bracket; the bracket is connected with the connection plate through a bolt; a jackscrew is connected with the sliding member through a threaded hole in the sliding member; and another jackscrew is connected with the compaction member through a threaded hole in the end cover. According to the device provided by the utility model, the drilled core sampling operation is carried out on irregular rock mass; and a fixture firmly clamps the rock mass, the vibration of the rock mass in the sampling process is eliminated, and the problems of drill jam and rock core breakage are solved.

Description

Irregular rock core boring sampling device

Technical field

The utility model belongs to Geotechnical Engineering field, relates to a kind of core boring sampling device that rock material mechanical test test specimen is made that is applied to, particularly for the irregular rock core boring sampling device of irregular rock.

Background technology

According to existing testing regulations, the mechanical property test of rock need to be made cylinder specimen mostly, sillar need be transported to laboratory and carry out core boring sampling.But the most profile irregular of the sillar of collection in worksite, the sillar that on market, existing brill core machine can only fixed profile rule, cannot fix or clamp shakiness for irregular rock, easily causes problems such as boring core machine bit freezing or core fracture.Therefore, need to use large-scale Rock cutting equipment that sillar is cut into rule body, then carry out core boring sampling operation.But so not only lost time but also increased experimentation cost, for not having the laboratory of large-scale Rock cutting equipment cannot complete sampling work.

Summary of the invention

Technical problem to be solved in the utility model is: for the fixing deficiency of irregular rock of current core boring sampling machine, provide the fixedly device of rig and irregular rock, realized the core boring sampling operation to irregular rock.

It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme: irregular rock core boring sampling device, comprise rig, drill bit, support, pedestal, web joint, end cap, pressure strip, saddle, pressurization rotating disk, the base framework both sides of described device are arranging respectively two joist steel crossbeams and are forming an orthogonal pedestal with the Plate Welding at longitudinal two ends, between two joist steel crossbeams of pedestal homonymy, be reserved with space, its spacing matches with saddle size, forms the sliding guide groove of saddle; End cap is bolted on the side of pedestal one end, the top of the pedestal other end is arranging web joint, rig, drill bit and pressurization rotating disk are combined and are assembled on support, and support is connected with web joint by bolt, makes rig, drill bit and pedestal become integral body; Jackscrew is connected with saddle by the threaded hole on saddle, and rear end is connected with crank; Another piece of jackscrew passes end cap by the threaded hole on end cap, and front end matches with the spacing hole on pressure strip, and rear end is connected with another crank.

Irregular rock is put into after pedestal, by adjust the jackscrew of pressure strip and the left and right sides and be aided with the lumps of wood, block rubber can make sillar firmly be fixed in pedestal.The utility model can be long to 600mm() * 450mm(is wide) * 300mm(is high) with interior irregular rock, carry out core boring sampling, be equally applicable to the concrete test block in above range of size; Can drill through different-diameter, the test specimen of length≤300mm.

The beneficial effects of the utility model: the utility model has been realized the core boring sampling operation to irregular rock; Fixture to sillar clamping firmly, has been eliminated the vibrations of sillar in sampling process, has solved bit freezing and core breakage problem; The design of employing combined type, is convenient to assembling, dismounting, transportation, and part replacement is convenient.

Embodiment

Embodiment 1, irregular rock core boring sampling device, as shown in Figure 1, Figure 2, Figure 3 shows, comprise rig 1, drill bit 2, support 3, pedestal 5, web joint 6, end cap 7, pressure strip 8, saddle 9 and pressurization rotating disk 4, the base framework both sides of described device are arranging respectively two joist steel crossbeams and are forming an orthogonal pedestal 5 with the Plate Welding at longitudinal two ends, between two joist steel crossbeams of pedestal 5 homonymy, be reserved with space, its spacing matches with saddle 9 sizes, forms the sliding guide groove of saddle 9; End cap 7 is fixed on the side of pedestal 5 one end by bolt 12, the top of pedestal 5 other ends is arranging web joint 6, rig 1, drill bit 2 and pressurization rotating disk 4 are combined and are assembled on support 3, support 3 is connected with web joint 6 by bolt 12, makes rig 1, drill bit 2 become integral body with pedestal 5; Jackscrew 10 is connected with saddle 9 by the threaded hole on saddle 9, and rear end is connected with crank 11; Another piece of jackscrew 10 passes end cap 7 by the threaded hole on end cap 7, and front end matches with the spacing hole 13 on pressure strip 8, and rear end is connected with another crank 11.

In practical operation, sillar is put into pedestal 5, between pressure strip 8 and sillar, put into the lumps of wood and block rubber, rotate jackscrew 10 and promote pressure strip 8, sillar is pushed against in the interior front and back of pedestal 5, adjust the position of saddle 9, rotate jackscrew 10 and place the lumps of wood at front end, make sillar left and right fixing.Connect rig power supply and cooling water pipe, manual operation pressurization rotating disk 4 moves downward drill bit, increase dynamics keep uniform force application after contact sillar after drill bit creeps into about 10mm, can connect stiff rod and hang weight semi-automatic the completing of rig crept on the handle of pressurization rotating disk 4.
