Description

Technical Field

[0001] The invention relates to the field of smooth surface blasting construction, in particular to a water bag fixing and releasing device for concentrated energy water pressure smooth surface blasting. Background Art

[0002] Focused water pressure smooth blasting is an advanced technology that combines the advantages of traditional linear focused blasting and water pressure blasting. Water bags, rod-shaped focused tubes and cylindrical gun mud are filled into the blasthole on the smooth blasting in a certain order; the focused tube explosives in the blasthole, from the explosion at the detonation point to the completion of the explosion of the explosives, propagate in the explosives What is the detonation wave, the detonation wave transmitted to the space of the blasthole along the direction of the blasthole is called the shock wave, and the shock wave transmitted to the surrounding rock of the blasthole is called the stress wave. The tunnel blasting method of filling the blasthole with water bags reduces the energy loss of the shock wave to the greatest extent possible and prevents the explosion gas from rushing out of the blasthole mouth. Compared with the tunnel blasting excavation without backfilling and blocking currently widely used in the country, the tunnel blasting method of filling the blasthole with water bags significantly improves the utilization rate of explosives, that is, the utilization rate of stress waves and explosion high-pressure gases generated by the explosion of explosives is improved, which is very beneficial to the crushing of surrounding rocks, and can improve construction efficiency and economic benefits while protecting the environment.

[0003] One of the steps in the construction process of energy-focused water pressure smooth blasting is to fill the water bag, which is a plastic bag filled with tap water. The size of the water bag is selected according to the diameter of the blasthole. Generally, the water bag is filled with 90% of water, and then the mouth of the water bag is tied tightly for use.

[0004] A large number of blasting holes will be drilled on the smooth blasting surface, and each blasting hole will be filled with blasting materials such as water bags, detonators, explosives and gun mud. There will be residues in the drilled holes, such as some sharp stones and other objects, and the depth of the blasting holes is generally 2-5 meters deep. These water bags, energy-focusing tubes, gun mud and other blasting materials are pushed into the blasting holes through the existing pushing rods. Sharp objects will puncture the water bags, or some non-rigid gun mud will be scraped against sharp objects during the pushing process, and the gun mud will lose its blocking effect. A lot of manpower and material resources will be required to remove it and resume work, which will seriously affect the construction efficiency.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Reference Figure 1 - Figure 7 A water bag fixing and releasing device for energy-gathering water pressure smooth blasting, comprising a plate body 1, the cross section of the plate body 1 is in an arc shape, notches 2 are provided at the lower edge positions of both ends of the plate body 1, a driving wheel 3 is rotatably connected to the notch 2 at one end of the plate body 1, a driven wheel 4 is rotatably connected in the notch 2 at the other end of the plate body 1, a conveyor belt 5 is sleeved between the driving wheel 3 and the driven wheel 4, the upper belt body of the conveyor belt 5 is located in the plate body 1, and the lower belt body of the conveyor belt 5 is located on the lower surface of the plate body 1; a crank 6 is fixedly connected to the end of the rotating shaft of the driving wheel 3;

[0034] The water bag fixing and releasing device designed in this embodiment is made of a plate body 1 made of an aluminum alloy material with high strength and light weight, which is convenient for blasting personnel to construct. In addition, the plate body 1 made of the aluminum alloy material can reduce labor intensity as much as possible for higher blast holes on smooth surface blasting. As for the overall length of the water bag fixing and releasing device, it can be tailored according to the depth of the blast hole;

[0035] The width of the plate body 1 is set to be slightly smaller than the diameter of the blasthole, ensuring that the plate body 1 and the conveyor belt 5 can be smoothly inserted into the blasthole;

[0036] The specific operation steps of the water bag fixing and releasing device are as follows:

[0037] The first step is to discharge the material, and place the water bag 101 on the conveyor belt 5. At this time, the plate body 1 with an arc-shaped cross section can half-wrap the water bag 101. In order to ensure the stability of the water bag 101, that is, when the plate body 1 is in a tilted state, the water bag 101 can still be placed on the conveyor belt 5. Double-sided tape can be used to adhere the water bag 101 to the conveyor belt 5, and it will not affect the subsequent separation of the water bag 101 from the conveyor belt 5;

[0038] The second step is feeding, inserting the other end of the plate body 1 into the blasthole, and then pushing the plate body 1 to the bottom of the blasthole. During the pushing process, the plate body 1 covers the inside of the blasthole to prevent the water bag 101 from contacting with sharp objects;

[0039] The third step is to unload the material, turn the crank 6, the crank 6 drives the driving wheel 3 to rotate, the driving wheel 3 drives the driven wheel 4 through the conveyor belt 5, and the conveyor belt 5 conveys the water bag 101 to the bottom of the blasthole, and then pull the plate body 1 out of the blasthole. While pulling the plate body 1, the stroke of pulling the plate body 1 out of the blasthole is the length of one water bag 101, while turning the crank 6, the conveyor belt 5 pushes the water bag 101 to the bottom of the blasthole, and the installation of the water bag 101 is completed at this time;

[0040] In the fourth step, the remaining materials are installed. The energy-gathering tube 102 can be placed on the conveyor belt 5. The sequential movement of the conveyor belt 5 will lay the energy-gathering tube 102 in the blasthole, and the plate body 1 will also be pulled outward, and the end of the detonating cord 103 of the energy-gathering tube 102 will be reserved outside the blasthole. Then, the water bag 101 is placed on the conveyor belt 5, and steps 1, 2 and 3 are performed in sequence. Finally, gun mud 104 for plugging the blasthole is placed on the conveyor belt 5, and the operation of the gun mud 104 is the same as the installation of the water bag 101, and steps 1, 2 and 3 are performed in sequence. Finally, the explosive material filled in the blasthole is as follows: Figure 5 As shown, the explosive material is filled with one of them and is filled according to the actual situation;

[0041] The water bag fixing and releasing device designed in the present embodiment can, firstly, ensure that the water bag 101 is safely pushed into the blast hole in terms of the filling and installation of the water bag 101. At the same time, the operating plate 1 can be easily realized according to the filling and installation position of the water bag 101, and it is relatively easy to push and fill other blasting materials. It can also be smoothly realized, and the rod-shaped blasting material of the energy-gathering tube 102 can be smoothly pushed into the blast hole, as well as the non-rigid gun mud 104. During the pushing process, its integrity can also be guaranteed to ensure the sealing of the blast hole.

[0042] Reference Figure 1 - Figure 7 The plate body 1 is provided with an arc-shaped cover plate 7 near the other end thereof, the cover plate 7 and the plate body 1 form a cylindrical body 8, and a plurality of inspection windows 9 are provided on the cover plate 7;

[0043] The cover plate 7 and the plate body 1 are arranged to form a cylindrical body 8 with a protective function. Before the water bag 101 or the easily broken cannon mud 104 is filled into the blasthole, the water bag 101 or the cannon mud 104 and other easily damaged blasting materials can be placed in the cylindrical body 8. The total length of the cylindrical body 8 is set, and multiple water bags 101 or a combination of water bags 101 and cannon mud 104 can be placed in the cylindrical body 8 at one time, which can further improve the construction efficiency;

[0044] Taking the water bag 101 as an example, the water bag 101 is placed on the conveyor belt 5, first transported into the cylinder 8, and close to the other end of the plate body 1, and then the installation steps one and two are performed to push the water bag 101 to the bottom of the blast hole. When the water bag 101 connects to the plate body 1 and extends into the blast hole, the cylinder 8 covers the water bag 101 to prevent some sharp objects at the top of the blast hole from puncturing the water bag 101, thereby further protecting the water bag 101.

[0045] Reference Figure 1 - Fig. 9 , the surfaces of the driving wheel 3 and the driven wheel 4 are radially provided with an annular groove 10, and the cross-sectional shape of the belt body of the conveyor belt 5 is adapted to the shape of the annular groove 10; the surface of the conveyor belt 5 is provided with a plurality of push plates 11;

[0046] The driving wheel 3 and the driven wheel 4 are both provided with an annular groove 10, and the conveyor belt 5 moves in the annular groove 10, and the belt cross section of the conveyor belt 5 is as follows: Fig. 9 As shown, the two edges of the upper belt body of the conveyor belt 5 are higher than the middle position, and when conveying the water bag 101 or the taphole mud 104, there will be no side deviation, so that the water bag 101 or the taphole mud 104 can be stably conveyed to the inside of the blasthole;

[0047] A plurality of push plates 11 are arranged on the conveyor belt 5. As described above, in order to increase the temperature of the water bag 101 on the conveyor belt 5 and prevent the water bag 101 from sliding relative to the belt body of the conveyor belt 5, the water bag 101 can be bonded to the bag body by double-sided adhesive. This method also has certain defects. The surface of the belt body of the conveyor belt 5 needs to be clean and tidy to ensure the firmness of the bonding of the water bag 101. Moreover, there is a lot of dirt and dust in the blasthole, and it is difficult to ensure the cleanliness of the belt body of the conveyor belt 5. For this reason, the push plate 11 is arranged, and the push plate 11 plays the role of limiting the blasting material.

[0048] When the blasthole is tilted downward, the blasting material can also be limited, and the specific limiting principle of the push plate 11 is as follows: the water bag 101 or the cannon mud 104 is placed between two adjacent push plates 11, and the conveyor belt 5 drives the water bag 101 or the cannon mud 104 to move through the push plate 11, and pushes the water bag 101 or the cannon mud 104 into the blasthole, and the steps 2 and 3 can be followed;

[0049] The push plate 11 can not only push the blasting material in a limited position, but also scrape and remove the debris inside the blasthole. Before step one, first insert the plate body 1 into the blasthole. During the insertion process, the crank handle 6 is driven to rotate while the plate body 1 is pushed into the blasthole. The conveyor belt 5 drives the push plate 11 to move. The push plate 11 gradually scrapes and pushes out the debris inside the blasthole, which helps to fully fill the subsequent blasting material. After scraping it clean, take out the plate body 1 and proceed according to steps one, two and three.

[0050] Reference Figure 1 - Fig.11 Each of the push plates 11 includes a top plate 12 and a base 13, the base 13 is fixedly connected to the surface of the conveyor belt 5, a notch 14 is provided on the base 13, a swivel 15 is provided in the notch 14, an end of the swivel 15 is rotatably connected to the inner wall of the notch 14 through a torsion spring 16, and the top plate 12 is fixedly connected to the swivel 15;

[0051] When encountering some fixed foreign objects in the blasthole, the push plate 11 will directly press against the foreign objects, making it difficult to drive the conveyor belt 5. For this purpose, a push plate 11 is provided that can avoid the fixed foreign objects by itself. When the top plate 12 contacts the fixed foreign objects, the top plate 12 drives the swivel 15 to rotate, and the swivel 15 deflects in the recess 14. The top plate 12 avoids the fixed foreign objects and detaches from them. After that, the subsequent top plates 12 squeeze the fixed foreign objects in turn, loosen the fixed foreign objects, and push them out of the blasthole, providing a good filling environment for the blasting materials.

[0052] Reference Figure 1 - Fig.11 Each of the top plates 12 includes a steel plate 17 and a rubber plate 18; one edge of the steel plate 17 is fixed to the swivel 15, and the other edge of the steel plate 17 is sleeved with the rubber plate 18;

[0053] The top plate 12 is composed of a steel plate 17 and a flexible rubber plate 18. The steel plate 17 plays a supporting role and can support the blasting material. At the same time, it provides support force for the flexible rubber plate 18, so that the rubber plate 18 can effectively push foreign objects in the blasthole. The flexible rubber plate 18 is used to protect blasting materials that are easily damaged, such as the water bag 101 and the gun mud 104, to avoid squeezing and damaging the blasting materials when the blasting materials are pushed into the blasthole by the conveyor belt 5.

[0054] Reference Figure 8 - Fig. 9 The surfaces of the driving wheel 3 and the driven wheel 4 are provided with anti-skid protrusions 19, and the anti-skid protrusions 19 are arranged on the surface of the annular groove 10; the inner surface of the belt body of the conveyor belt 5 is provided with a plurality of grooves 20 adapted to the anti-skid protrusions 19, and the conveyor belt 5 moves around the driving wheel 3 and the driven wheel 4, and the anti-skid protrusions 19 are embedded in the grooves 20;

[0055] It has been explained above that the depth of the blasthole can reach five meters. The plate body 1 extends into the blasthole. The longer the length of the conveyor belt 5 is, the looser the conveyor belt 5 is. The conveyor belt 5 in the relaxed state will slip with the driving wheel 3 and the driven wheel 4. Especially when scraping and pushing out foreign objects in the blasthole, the moving resistance of the conveyor belt 5 is greater and the slipping phenomenon is more serious. For this reason, anti-slip protrusions 19 are provided on the driving wheel 3 and the driven wheel 4, and grooves 20 adapted to the anti-slip protrusions 19 are provided on the inner surface of the belt body of the conveyor belt 5. When the driving wheel 3 and the driven wheel 4 are in contact with the conveyor belt 5, the anti-slip protrusions 19 are embedded in the grooves 20, thereby improving the transmission stability and reducing the occurrence of slipping.

[0056] Reference Figure 1 - Figure 7 , scales 21 are provided on both sides of the plate body 1, and the scales 21 are used to measure the depth of the blasting hole;

[0057] Before executing step one, the plate body 1 is extended into the blasthole to scrape and remove foreign matter in the blasthole. At this time, the plate body 1 extends to the bottom of the blasthole, and the depth of the blasthole can be measured by the scale 21, which can provide specific data for the on-site operator again, which is equivalent to re-measuring the depth of the blasthole. When executing step two later, the operator can quickly push the plate body 1 into the blasthole until the scale line 21 is flush with the blasthole mouth, thereby improving the efficiency of executing step two and avoiding forcing the plate body 1 to the bottom of the blasthole, thereby squeezing and damaging the plate body 1 and the water bag 101 or the cannon mud 104 at its end.

[0058] 8. A water bag fixing and releasing device for smooth surface blasting with concentrated water pressure according to claim 2, characterized in that: the cover plate 7 is provided with an anti-scratch eave 22, the anti-scratch eave 22 is arranged at a position close to the other end of the plate body 1, and the end of the anti-scratch eave 22 is arranged tilted downward;

[0059] The anti-scratch eaves 22 are set, when the push plate 11 pushes the blasting material into the blasthole by the conveyor belt 5, the blasting material moves along the anti-scratch eaves 22 to prevent the blasting material from hitting the sharp foreign object surface at the bottom of the blasthole. At the same time, when the plate body 1 is pushed to the bottom of the blasthole, the plate body 1 is pressed against the bottom of the blasthole by the anti-scratch eaves 22, which also provides anti-collision protection for the plate body 1, and further avoids direct collision with the water bag 101 or the gun mud 104 placed at the other end of the plate body 1.

[0060] Reference Figure 1 - Figure 7 , a plurality of support rods 23 are rotatably connected to both sides of the plate body 1, and a connecting rod 24 is rotatably connected to the support rods 23 on the same side;

[0061] The support rod 23 is provided for setting up the plate body 1 in the blasthole. When the push plate 11 cleans the foreign matter inside the blasthole, when executing step three, the connecting rod 24 is pushed, and the connecting rod 24 drives the support rod 23 to rotate from a horizontal state to a vertical state. The support rod 23 supports the plate body 1 to be set up inside the blasthole. At this time, the edge of the push plate 11, that is, the edge of the rubber plate 18, no longer contacts the lower surface of the blasthole. At this time, the conveyor belt 5 transmits the blasting material without resistance, and the crank handle 6 can be easily driven to push the blasting material into the blasthole.

[0062] Reference Figure 1 - Figure 7 , a handle 25 is provided at one end of the plate body 1, and the handle 25 is arranged vertically downward;

[0063] Smooth blasting will drill many blast holes, each of which has a different height. In order to facilitate the filling of blasting materials into the high blast holes, a handle 25 is provided at one end of the plate body 1. The handle 25 facilitates the pushing of the plate body 1 into the blast hole, and the lower end of the handle 25 can cooperate with the V-shaped support leg 26. Figure 1 - Figure 3 As shown, the intersection of the support legs 26 is sleeved on the handle 25, and the board body 1 is supported and erected, making it convenient for operators to control the board body 1.

[0064] Working principle:

[0065] First, insert the plate body 1 into the blasthole. During the insertion process, the crank handle 6 is driven to rotate while the plate body 1 is pushed into the blasthole. The conveyor belt 5 drives the push plate 11 to move. The push plate 11 gradually scrapes and pushes out the debris inside the blasthole, which helps to fully fill the subsequent blasting materials. After scraping clean, take out the plate body 1, and then place the water bag 101. The specific steps are as follows:

[0066] The first step is to discharge the material, and place the water bag 101 on the conveyor belt 5. At this time, the plate body 1 with an arc-shaped cross section can half-wrap the water bag 101. In order to ensure the stability of the water bag 101, that is, when the plate body 1 is in a tilted state, the water bag 101 can still be placed on the conveyor belt 5. Double-sided tape can be used to adhere the water bag 101 to the conveyor belt 5, and it will not affect the subsequent separation of the water bag 101 from the conveyor belt 5;

[0067] The second step is feeding, inserting the other end of the plate body 1 into the blasthole, and then pushing the plate body 1 to the bottom of the blasthole. During the pushing process, the plate body 1 covers the inside of the blasthole to prevent the water bag 101 from contacting with sharp objects;

[0068] The third step is to unload the material, turn the crank 6, the crank 6 drives the driving wheel 3 to rotate, the driving wheel 3 drives the driven wheel 4 through the conveyor belt 5, and the conveyor belt 5 conveys the water bag 101 to the bottom of the blasthole, and then pull the plate body 1 out of the blasthole. While pulling the plate body 1, the stroke of pulling the plate body 1 out of the blasthole is the length of one water bag 101, while turning the crank 6, the conveyor belt 5 pushes the water bag 101 to the bottom of the blasthole, and the installation of the water bag 101 is completed at this time;

[0069] In the fourth step, the remaining materials are installed. The energy-gathering tube 102 can be placed on the conveyor belt 5. The sequential movement of the conveyor belt 5 will lay the energy-gathering tube 102 in the blasthole, and the plate body 1 will also be pulled outward, and the end of the detonating cord 103 of the energy-gathering tube 102 will be reserved outside the blasthole. Then, the water bag 101 is placed on the conveyor belt 5, and steps 1, 2 and 3 are performed in sequence. Finally, gun mud 104 for plugging the blasthole is placed on the conveyor belt 5, and the operation of the gun mud 104 is the same as the installation of the water bag 101, and steps 1, 2 and 3 are performed in sequence. Finally, the explosive material filled in the blasthole is as follows: Figure 5 As shown, the explosive material is filled with one of them and is filled according to actual conditions.
