Description
Technical field
The utility model relates to a kind of detection forming pressure device, particularly relates to a kind of pressure device that is applicable to ature of coal or rock moulding detection usefulness.
Background technology
It is an important indicator of geologic prospecting industry sample detecting that ature of coal and rock composition are identified, the sample of just having adopted carries out the observation of pressure forming, microscopically after operation such as need pulverizing again.And in the coal petrography forming process, the forming pressure device is particularly important.Existing coal petrography forming pressure device belongs to the level type assistor more, and its afterburning mode adopts lever principle, goes up (descending) and presses lever, makes the coal petrography moulding.When adopting this pressure device that coal dust is carried out reinforcing, because press rods is the motion reinforcing of the above-below direction fixed, and the plane is not complete level on the coal dust in the moulding door frame, so cause the coal dust discontinuity in the moulding door frame easily, eminence is stressed greatly, lower is stressed little, and molded like this coal sample density unevenness is even, can't obtain good observations at microscopically, make that the product that extrudes is a waste product, caused the waste of resource.In addition, level type pressure device is the reinforcing of pressure column lower surface to the coal dust partial points, and most of moulded coal hardness that extrudes is inhomogeneous, causes other test result distortions of coal petrography.
Summary of the invention
The purpose of this utility model is to provide a kind of detection forming pressure device, this pressure device adopts rotation mode to carry out reinforcing, by rotational pressure post at a slow speed, can polish non-level coal dust in the moulding door frame, it is stressed to make that coal dust evenly distributes, and is specially adapted to ature of coal or rock moulding, and the sample rate of extrusion and hardness are very even, examine under a microscope effectively, the gained test result is accurately true.
The purpose of this utility model is achieved through the following technical solutions:
A kind of detection coal petrography forming pressure device, this pressure device comprises upper bracket, draw-in groove, movable bearing support, base, moulding door frame, pad, pressure column, afterburning screw thread, grip bar and pillar; Wherein, the along continuous straight runs setting from top to bottom of upper bracket, draw-in groove, movable bearing support, base, pillar vertically is provided with; Upper bracket, draw-in groove, base and pillar are affixed, and an end of movable bearing support is with column articulated, and draw-in groove and moulding door frame join, and moulding door frame lower end and pad join, and pad places on the movable bearing support; Upper bracket is threaded with afterburning screw thread, and afterburning screw thread is connected by screw with pressure column, and grip bar and afterburning screw thread are affixed.
Aforesaid a kind of detection coal petrography forming pressure device, its movable bearing support is provided with groove, and groove and pillar join.
Aforesaid a kind of detection coal petrography forming pressure device, its pressure column lower end is horizontal.
Aforesaid a kind of detection is adopted buttress thread with coal petrography forming pressure device, its afterburning screw thread, and top, its underpart is a sphere.
Advantage of the present utility model and effect are:
1. the utility model assistor adopts rotation mode to carry out reinforcing, belongs to aspectant afterburning mode, and it passes through rotational pressure post at a slow speed, can polish non-level coal dust in the moulding door frame, and it is stressed to make that coal dust evenly distributes;
2, the utility model assistor adopts buttress thread, can slow down the pressure column decline rate and make coal dust stressed more even;
3. the utility model pressure column adopts sphere to contact with afterburning screw thread, like this in the process of pressing down behind the pulverized coal forming upper and lower surface more smooth;
4. the groove of the utility model movable bearing support has polarization and supportive preferably, makes that simultaneously the coal column after the moulding is convenient to take out;
5, the sample rate and the hardness that extrude of the utility model is very even, examines under a microscope effectively, and the gained test result is accurately true.
