Description
Technical field
The utility model belongs to the deep hole blasting technology field, is specifically related to make the tamper of a kind of deep hole blasting powder charge of coal seam or rock stratum presplitting.
Background technology
At present, in the coal mine down-hole tunnel driving blasting process, blast hole depth is more shallow, usually uses wooden or Drawing expansion bar (see Chinese patent " specific purpose tool that uses when processing borehole in a kind of mining, the down-hole driving production process ", the patent No. is 00237316).And for the deep hole blasting of hole depth above 50m, as carrying out anti-reflection to the coal seam or the back production roof being carried out the explosion reduction, adopt the coal mine gas extraction blasting grain of moulding (to see Chinese patent " coal mine gas extraction blasting grain ", the patent No. is 200920173412.X) in the big gun hole of packing into, because the big gun hole is dark (greater than 50m), adopts bamboo or wooden tamper, except length is restricted, the intensity of itself is also lower, is difficult to the explosion powder column is sent to bottom, big gun hole.Adopt sectional charging tamping bar for deep-hole blasting (seeing that Chinese patent " sectional charging tamping bar for deep-hole blasting " patent No. is CN97249519.3), become the tamper of the thick middle thin likeness in form in two ends " dumbbell " with light wood or plastic processing.During construction operation, being saved land by discrete tamper one joint top one enters in the big gun hole, pushes away one by " rod " joint with rope again and saves land and pull out outside the big gun hole, but do not connect between the tamper, and intensity is low, and is easy to use less than 30m big gun hole for hole depth; Chinese patent discloses a kind of tamper (patent No. 201020181956.3), it comprises: head tamper and by the tamper unit combination of some end to end tamper cell formations, the tamper unit that this head tamper is adjacent with this tamper unit combination is the first tamper unit, grafting one sleeve between described head tamper and described the first tamper unit, the sleeve of all pegging graft between the adjacent tamper unit of described tamper unit combination, this tamper easy accessibility, speed is fast, efficient is high, guaranteed powder charge speed, but this tamper adopts metal tube and metal joint thereof, not only the tamper dead weight is heavier, artificial drug delivery effort, in the process of even more serious iron tamper not drug delivery in the big gun hole, inevitably the bump explosive is absolutely unsafe.
The utility model content
In order to overcome tamper material and the structural deficiency of existing deep hole blasting powder charge, the utility model provides a kind of lightweight, the safe and reliable tamper that is used for the deep hole blasting powder charge.
Concrete technical scheme of the present utility model is as follows:
The tamper that is used for the deep hole blasting powder charge comprises body, upper binding head and the lower union joint of flame retardant plastics; Described upper binding head is the plastic tubulature of both ends open, and the upper end outer wall of upper binding head is provided with external screw thread, the body interference fit of lower end inwall and flame retardant plastics, and use the PVC glue bond; Described lower union joint is the plastic tubulature of both ends open, the upper end inwall of lower union joint and the body interference fit of flame retardant plastics, and use the PVC glue bond, the lower end inwall is provided with internal thread.
The external screw thread of described upper binding head upper end and the internal thread of lower union joint lower end are complementary.
The internal diameter of described upper binding head upper external screw thread part is less than the external diameter of body; The intersection of the external screw thread of upper end outer wall and the outer wall of lower end is provided with the hexagon edges and corners.
Internal thread and the intersection between the inwall of upper end of described lower union joint lower end inwall are provided with interior.The intersection of the outer wall of lower end internal thread and the outer wall of upper end is provided with the hexagon edges and corners.Characteristics of the present utility model are that to select fire-retardant plastic tube be tamper, and two ends respectively are provided with upper binding head and the lower union joint that male and female connects, and connect reliably between the tamper, use safety.
Another characteristics of the present utility model are that tamper is lightweight, and connecting length is long, push away the medicine Heavy Weight, and the intensity of the connector between the tamper guarantees once to push away the explosion powder column fracture and coming off not more than the 30Kg in 100m big gun hole.
Another characteristics of the present utility model are of many uses, not only as tamper, and can be used as inspecting hole pipe and hole flushing pipe, namely before powder charge, finding when carrying out inspecting hole with this tamper has residue in the big gun hole, and direct water filling flushing big gun hole in the tamper then is smooth and easy when guaranteeing the powder charge of explosion powder column.
The utility model has the advantage of that use is safe, lightweight, intensity is large, connects reliably, and inspecting hole, hole flushing and drug delivery are convenient, are convenient to promote the use of.
