Description

A kind of Novel hole male extension element

Technical field

The utility model relates to a kind of Novel hole male extension element, belongs to blasting material field.

Background technology

In-hole short delay explosion to be realized in large-scale Multi hole blasting, medium-length hole blasting process; Demolition blasting, for reducing slungshot, reduces air-shock wave intensity, reduces earthquake sheet, also adopts short-delay blasting more.In short-delay blasting many employings hole, outside hole, use other delay detonator of different section to realize, but do not delay to be subject to detonator section in hole not and the restriction of short time interval control technology, well can not control short-delay time.Therefore, in the special blasting such as medium-length hole blasting, demolition blasting, normal adopt hole male extension and delay in hole to match, present stage hole male extension adopt other delay detonator of different section connection blasting network, make blasting network each portion delayed ignition.But use delay detonator to connect blasting network to realize short-delay blasting outside hole, blasting network design is complicated, connect loaded down with trivial details, use cost is high, and delay detonator explosion time produces metal film flying, easily damages the blasting network of surrounding, once damage the network of non-propagation of explosion, then can cause subnetwork cannot propagation of explosion, cannot detonate according to desired design in part big gun hole, cause explosion failure.

Utility model content

For the problems referred to above solving extension in existing short-delay blasting construction, hole male extension means exist, the utility model provides a kind of Novel hole male extension element, the requirement of hole male extension is completed by delay powder, strengthen the accuracy of hole male extension, substitute the use of present stage delay detonator, realize the short-delay blasting reducing explosive quantity in a sound.The utility model has use safety, and blasting network is convenient and fast connection, and use cost is low, the advantage that environmental pollution is little.

The purpose of this utility model is achieved by the following technical programs: a kind of Novel hole male extension element is made up of incoming end, shell two parts, comprising: screw thread, the blast chamber that disappears, delay element, delay powder, moistureproof sheet, four-way, priming.It is characterized in that: described incoming end is " convex " type structure, and its main part is cylinder, and projection is a small cylinder, and projection outer wall establishes screw thread; Body cylindrical is coaxial with protrusion cylinder, axis slotting, and slotting has formed blast hole in the part of body cylindrical, and its internal diameter is consistent with detonator external diameter, and slotting forms in the part protruded the blast chamber that disappears.Shell is divided into two parts, front portion is set up separately " recessed " type delay element, and its external diameter equals shell internal diameter, and screw thread established by " recessed " mouth wall, and delay element axis place establishes delay powder, and delay powder " recessed " mouth place sets up defences damp sheet; Rear portion is divided into four-way, and described four-way is four crossing column type slottings, and four moistureproof sheets are established in four slottings and priming contact position, and the diameter of four slottings is equal to detonator external diameter; To set up defences successively between delay element bottom and four-way damp sheet, priming.Described incoming end, shell are threaded connection.

During use, incoming end, shell are threaded connection into an entirety, and incoming end inserts a detonator, and four-way inserts four detonators.Ignite incoming end detonator, the flame of detonator end ejection punctures moistureproof sheet and lights delay powder, delay powder burning is to end, burn moistureproof sheet and light priming, after this priming ignites, burning transfers detonation to rapidly, punctures moistureproof sheet, thus ignite four, four-way place detonator, complete the function that outside whole hole, Millisecond Blasting is delayed.

A kind of Novel hole male extension of the utility model element, is made up of incoming end, shell two parts, comprises: screw thread, the blast chamber that disappears, delay element, delay powder, moistureproof sheet, four-way, priming.The slotting of described incoming end axis, this slotting has formed blast hole in the part of body cylindrical, and its internal diameter is consistent with detonator external diameter, is convenient to the insertion of detonator, fixes, slotting forms in the part protruded the blast chamber that disappears, and can reduce igniter pressure, be conducive to improving igniting reliability.Described shell is divided into two parts, front portion is set up separately " recessed " type delay element, its external diameter equals shell internal diameter, being convenient to delay element is fixed in shell, screw thread established by " recessed " mouth wall, match with the screw thread on incoming end, make incoming end and shell connect into an entirety, form a kind of Novel hole male extension element.Delay element axis place establishes delay powder, defer time is controlled by the formula, the length that change delay powder, complete the extension function of a kind of Novel hole male extension of this utility model element, rear portion is divided into four-way, described four-way is four crossing column type slottings, the diameter of four slottings is equal to detonator external diameter, is convenient to insert.Fix four detonators, connect Millisecond Blasting; Four slottings and priming contact position, delay powder " recessed " type place, damp sheet of all setting up defences between delay element bottom and four-way, prevent delay powder, the priming moisture absorption, affect the stability of a kind of Novel hole male extension of this utility model element; Priming is established in delay element bottom, ignites four-way place detonator.The setting of screw thread, can make incoming end, shell two parts firmly link together.

Advantage and the good effect of a kind of Novel hole male extension of the utility model element are: by delay powder to complete the requirement of hole male extension, strengthen the accuracy of hole male extension, substitute the use of present stage delay detonator, realize the short-delay blasting reducing explosive quantity in a sound.The utility model has use safety, and blasting network is convenient and fast connection, and use cost is low, the advantage that environmental pollution is little.

The technical scheme of a kind of Novel hole male extension element that the utility model provides is described in detail below in conjunction with example.
