Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a compound blast hole blocking device with a pipe body provided with a sealing ring and a filling material, which can solve the problems in the prior art.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The invention provides a compound blast hole plugging device with a pipe body provided with sealing rings and filled with filler, as shown in figures 1 and 2, the device comprises a pipe body 1 and a plurality of sealing rings 2, wherein the sealing rings 2 are fixedly sleeved on the pipe wall of the pipe body 1, one end of the pipe body 1 is closed to form a closed end 3, the other end of the pipe body 1 is provided with an opening to form an open end 4, the pipe body 1 is internally provided with the filler, the filler uses a material which is easily obtained in a blasting field as the filler instead of conventional stemming, therefore, the filler can be obtained from the field and manufactured on the field, the sealing rings 2 can form interference fit with blast holes, the friction force between the compound blast hole plugging device with the pipe body provided with the sealing rings and filled with the filler and the blast holes is increased, the sealing performance is enhanced, the pipe body 1 and the sealing rings 2 are both made of flexible flame-retardant materials, the pipe body provided by the application is provided with the sealing rings and the compound blast hole plugging device with the filled with the filler, therefore, when the double-entry blasthole plugging device with the sealing ring and the filler therein is inserted into a blasthole, the body 1 and the sealing ring 2 are in full contact with the blasthole wall, the contact area of the body and the sealing ring is increased to the maximum extent, friction is increased, and the body 1 and the sealing ring 2 are foldable, which is low in transportation cost, so that the double-entry blasthole plugging device with the sealing ring and the filler therein can be manufactured without a blasting site, but the manufacture of the filler and the filling of the filler into the body with the sealing ring and the filler therein need to be performed in the site so as to maintain the humidity of the filler, and further, the body 1 and the sealing ring 2 are both flexible flame retardant materials, so that the body 1 and the sealing ring 2 are not ignited when a powder lead of the gunpowder is ignited, and therefore, the double-entry blasthole plugging device with the body and the filler therein can be mass-produced, Convenient storage, difficult fracture, convenient operation when using it to block the big gun hole and its jam effect is better.
Further, the outer wall of sealing ring 2 is the round platform form, sealing ring 2 is along the cross sectional area crescent of the direction of keeping away from blind end 3, sealing ring 2 is flexible material, sealing ring 2 and big gun hole interference fit, therefore, behind the barrel 1 stopper into the big gun hole that will have round platform form sealing ring 2, because big gun hole wall surface is rougher, when sealing ring 2 has the trend of big gun hole outer movement, the border of the main aspects of round platform form sealing ring 2 can produce great static friction with big gun hole wall and prevent sealing ring 2 from taking place the motion, consequently, this barrel is equipped with the sealing ring and the compound big gun hole of the filler blocks up the device sealed effect better in.
Further, the sealing ring 2 is a circular truncated cone sleeve-shaped sealing ring 2, which can also be called as an umbrella shape, the small end of the sealing ring 2 is fixedly sleeved on the tube body 1, the cross-sectional area of the sealing ring 2 along the direction far away from the closed end 3 is gradually increased, the tube body 1 with the circular truncated cone sleeve-shaped sealing ring 2 can be easily plugged into a blast hole, and when the circular truncated cone sleeve-shaped sealing ring 2 receives thrust generated by gunpowder explosion in the blast hole, the circular truncated cone sleeve-shaped sealing ring is not easy to be pushed out from the blast hole, the sealing effect is improved, and further the blasting footage is increased.
Further, a sealing ring 2 is sleeved on the tube body 1 close to the closed end 3, and the edge of the small end of the sealing ring 2 close to the closed end 3 is 10 mm-12 mm, preferably 10mm, away from the closed end 3;
the pipe body 1 close to the opening end 4 is sleeved with a sealing ring 2, and the edge of the large end of the sealing ring 2 close to the opening end 4 is 20 mm-30 mm, preferably 20mm away from the opening end 4.
Further, the length of the sealing ring 2 along the axial direction of the pipe body 1 is 30-35 mm, preferably 33mm, the length of the pipe body 1 is 200-250 mm, preferably 220mm, but the length is not limited to the above dimensions, and the length of the pipe body 1 and the sealing ring 2 depends on the physical factors such as the diameter of the blast hole.
Further, be provided with the recess of a plurality of along 1 axis direction of pipe shaft on the pipe shaft 1, be provided with the recess of a plurality of along round platform generating line direction on the sealing ring 2, the circumference of pipe shaft 1 and sealing ring 2 all evenly is provided with the recess, make pipe shaft 1 and sealing ring 2 have the elasticity performance, when filling the filler, pipe shaft 1 that has the elasticity performance can hold more filler, it is more important, pipe shaft 1 and sealing ring 2 can the sudden expansion after receiving the impact of the high temperature high-pressure gas that the explosive explosion of big gun hole depths produced, frictional force between pipe shaft 1 and big gun hole wall and sealing ring 2 and the big gun hole wall sharply increases, strengthen sealed effect, maximum improvement blasting advances the chi.
Further, the pipe body 1 and the sealing ring 2 are made of flame-retardant polyvinyl chloride materials.
Furthermore, the filler is slurry or mortar, and common soil and sand particles are common on the blasting site, so that the materials are convenient to obtain.
Further, the inclination of the circular truncated cone shell is 31/2/3~31/2The included angle between the circular truncated cone shell and the pipe body is 30-60 degrees, the larger the inclination of the circular truncated cone shell-shaped sealing ring 2 is, and the pipe body is provided withThe sealing ring and the compound blast hole plugging device filled with the filler are better in sealing performance to the blast hole after being plugged into the blast hole, but when the inclination of the sealing ring is too large, the compound blast hole plugging device with the pipe body provided with the sealing ring and filled with the filler is not easy to plug into the blast hole, and therefore the inclination, the size and the like of the circular truncated cone shell-shaped sealing ring 2 are determined according to actual conditions.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
