Abstract
The utility model relates to a sectional explosive charging tamping bar for deep-hole blasting. The utility model is used for charging explosive for deep-hole rock blasting engineering. A dumb-bell type tamping bar is made of light wood or plastic. The both ends of the dumb-bell type tamping bar are thick, and the middle of the dumb-bell type tamping bar is thin. When in construction operation, the disconnected tamping bars are put into the blast hole joint by joint, and the disconnected tamping bars are pulled out of the blast hole by a head tamping bar with a rope joint by joint. The utility model effectively solves the problem that the full-length type tamping bar and the connected tamping bar has easy breaking, inconvenient operation and easy abandoned hole generation.
Description
The utility model is used for the blast hole charging medicine of the deep hole rock blasting of all kinds of engineering constructions, mine, metallurgy.
In the drillhole blasting engineering, the filling explosive requires with wooden or bamboo tamping rod powder stick to be escorted into big gun hole and compacting.When big gun hole hole depth is dark, use elongated tamper, the tamper of thin diameter is too soft, fractures easily; The tamper weight of thick diameter is big, and operating difficulties adopts the interconnection system tamper, promptly is processed into coupling head with metal (or engineering plastics) between the two joint tampers, couple together, but use is very inconvenient, in case joint takes off, the tamper that enters the big gun hole can't pump out, and is retained in the hole, promptly causes useless hole.
In the whole blasting engineering, boring is the heaviest operation, and powder charge is last critical process.Useless hole and inaccurate powder charge all can influence demolition effect or cause a serious accident.
No matter how dark the big gun hole is for segment type powder charge tamper, and jacking is extracted out smoothly, can address the above problem effectively.
The segment type tamper is made up of " rod ", " standard rod " two parts, and being saved land by unconnected tamper one joint top one each other enters the big gun hole and push the powder charge volume, so be referred to as " segment type tamper ".
Become the tamper of the thick middle thin likeness in form in two ends " dumbbell " with light wood or plastic processing, the centre carefully is in order to alleviate the tamper deadweight and to reduce the frictional resistance between tamper and the big gun hole wall and help draining, make 4 rhones at end particle size place, be " standard rod ".
On the particle size place, termination of " standard rod " centre position rhone, bore the hole of a diameter 5～6mm, wear the tether rope, be " rod ", rope resembles two " plaits " and must be exposed at outside the big gun hole all the time, outwards extract tamper when being used to load explosive out, a main function of " rod " be will enter the big gun hole in its back tamper again a joint one save land and pull out outside the big gun hole.
General, the tamper that every " rod " pulls out is controlled at 10m, when " the standard rod " that head into the big gun hole whenever surpasses 10m, then must establish one " rod " in addition, has two ropes to expose outside the big gun hole again, and too much to prevent the tamper that need pull out, rope is broken.It is the flexible steel cable of band rubber and plastic sheath of 2.5～3mm or the nylon rope of 3-4mm that rope is selected diameter for use, must prevent during construction that rope from being rubbed.
Tamper length: L=1～1.5m
Two ends diameter: D=(0.7～0.8) Φ; (Φ is a blasthole diameter)
Mid diameter: d=(0.4～0.5) Φ; (Φ is a blasthole diameter)
Wire rope handling aperture: φ=5～6mm
The utility model sees accompanying drawing for details.
1 is tamper two ends particle sizes among the figure, and 2 is middle thin footpath
3 is a rod lacing hole, and 4 is drain groove.
Claims (2)
1. deep hole blasting segment type powder charge tamper, be made up of a rod, standard rod, it is characterized in that: tamper is made up of mutual disjunct more piece, and each joint tamper is thick middle thin " dumbbell " shapes in two ends, particle size place, two ends has drain groove, and there is drag rope in the end system of a rod;
2. according to the deep hole blasting segment type powder charge tamper of claim 1, it is characterized in that: drag rope ties up in the lacing hole of rod termination.
