Abstract
The utility model relates to a variable diameter connector, in particular to a novel bidirectional variable diameter connector, which comprises a connector body. The connector is characterized in that the connector body is in a reducing cylindrical structure shape with a large tip and a small tip, a through hole is arranged in the middle of the connector body, the inner diameter of one end of the large tip of the connector body is designed into a positioning connection hole combining a hexagonal shape with a reducing cone, the positioning connection hole combining the hexagonal shape with the reducing cone matches with a drill rod, a connection hole of the reducing cone section is communicated with a connection hole of the inner diameter at one end of the small tip, and the outer diameter of one end of the small tip is designed into external threads matching with internal threads of a drill bit. The novel bidirectional variable diameter connector has simple structure, is simple and rapid in assembly without changing an original device structure, can increase rock drilling operation efficiency, and can be widely applied to underground mining industry.
Description
Technical field
The utility model relates to the reducer pipe connector, relates in particular to a kind of novel two-way reducing connector.
Background technology
The drilling tool that is used at present on the mining heading equipment of 7655 hammer drill and YG90 hammer drill does not have interchangeability.Be to solve the interchangeability problem, when using YG90 series bore bit and B22 drill steel series drilling tool to beat the centre bore (the groove heart) of driving with 7655 hammer drill, need make a call to 5 groove heart holes in the mining practical application of down-hole, this has increased the consumption of gunpowder and drilling tool undoubtedly.In addition, in the driving charge explosion, 5 groove heart hole arrangements and explosive payload and the time difference of detonating are wayward, and digging footage is produced considerable influence.If beat centre bore (the groove heart) difficulty of driving with YG90 hammer drill use YG90 bore bit very big, mainly is because YG90 hammer drill single-set operation does not have the unit support; Now downhole production is used has only YG90 stand or chassis, and these two kinds of rock drilling equipments move quite inconvenience, and the YG90 stand can only be beaten vertical fan face.Therefore need a kind of novel reducer union to solve this problem.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, designs a kind of increasing work efficiency and interchangeability and novel two-way reducing connector simple in structure.
The purpose of this utility model realizes by following technical proposals:
A kind of novel two-way reducing connector of the present utility model, comprise connector body, the profile that it is characterized in that described connector body is a big little undergauge cylindrical structure, the centre is provided with through hole, the internal diameter of the big first end of described connector body is designed to the location connection holes of hexagon and the combination of undergauge cone, the location connection holes and the drill steel of this hexagon and the combination of undergauge cone segments are complementary, the connecting hole of its undergauge cone segments communicates with the connecting hole of microcephaly's one end internal diameter, and the external diameter of its microcephaly's one end is designed to the external screw thread that is complementary with the bore bit internal thread.
Advantage of the present utility model and beneficial effect are: described novel two-way reducing connector is owing to adopted technique scheme, to organically be connected into one with matching used YG90 series bore bit of 7655 hammer drill and B22 drill steel, under the prerequisite of not changing rock drilling equipment and floor space, use 7655 hammer drill, can simple and easyly change YG90 series bore bit quickly, improved the rock drilling operating efficiency effectively, and because the location connection holes of the hexagon of two-way reducer union and the combination of undergauge cone segments can prevent B22 drill steel reducing connector effectively becomes flexible or throw switch; The external screw thread of two-way reducing connector can form left-handed self-locking with the internal thread of bore bit and connect.During the rock drilling operation, only need the B22 drill steel slightly point load onto this two-way reducing connector and just can use the serial bore bit of YG90 to carry out the rock drilling operation.Solved the drilling tool interchangeability problem on the mining heading equipment that is used for 7655 hammer drill and YG90 hammer drill.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lateral view of the utility model Fig. 1.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As Fig. 1, shown in Figure 2, a kind of novel two-way reducing connector of the present utility model, comprise connector body 1, the profile that it is characterized in that described connector body 1 is a big little undergauge cylindrical structure, the centre is provided with through hole, the internal diameter of the big first end of described connector body is designed to the location connection holes of hexagon 5 and 2 combinations of undergauge cone segments, this hexagon 5 and the location connection holes of undergauge cone segments 2 combinations and being complementary of drill steel, the connecting hole of its undergauge cone segments communicates with the connecting hole 4 of microcephaly's one end internal diameter, and the external diameter of its microcephaly's one end is designed to the external screw thread 3 that is complementary with the bore bit internal thread.
The location connection holes of the hexagon of two-way reducer union of the present utility model and the combination of undergauge cone segments can prevent effectively that B22 drill steel reducing connector is loosening or throw switch.The external screw thread of bore bit reducing connector can form left-handed self-locking with the internal thread of bore bit and connect.Easily assembled quick.The utility model is simple in structure, need not the original equipment structure is changed.Use the utility model can improve the rock drilling operating efficiency, the industry extensive use of can digging up mine in the down-hole.
