Description

Technical Field

[0001] The invention relates to an explosive binding device for water conservancy and hydropower blasting and a use method thereof. Background Art

[0002] At the water conservancy and hydropower construction site, there are many places that need to be blasted. The specific blasting method is to first drill a hole at the blasting location. According to the drilling depth, multiple cylindrical explosives (emulsion explosives) are first connected in series with detonating cords, and then multiple explosives are tied to a long pole. The distance between the explosives is kept uniform, and then the long pole is extended into the hole to carry out the blasting. The function of the long pole is to keep the spacing between multiple explosives in the hole fixed. The commonly used raw material of the long pole is bamboo strips.

[0003] At present, a manual method is adopted, in which a steel wire is taken to wrap around the explosives and the long pole, and the two ends of the steel wire are crossed and twisted together, so that the explosives are tied to the long pole by the steel bar. The binding strength depends on the workers, which requires the workers to have rich experience. When the binding strength is too small, the explosives are easy to fall off. When the binding strength is too large, the steel wire is easy to squeeze the plastic film on the surface of the explosives at the twisted position. This will not have much impact when used for blasting in dry holes, but water conservancy and hydropower construction sites often have wet geology, and even groundwater exists at the drilling location, which causes water to enter the explosives and reduces or loses the blasting effect, so the binding effect may be poor.

[0004] Blasting is a very dangerous process, and the corresponding preparation work is also relatively complicated, including reporting to the public security organs and clearing the site equipment and personnel. Each blasting requires a lot of preliminary preparation work. Therefore, centralized blasting is generally adopted, that is, all blasting work is concentrated together as much as possible to reduce the number of preliminary preparations. This results in a large number of explosives required for one blasting, and the efficiency of manual binding is low, which is difficult to meet the needs of the project. Summary of the invention

[0005] The purpose of the present invention is to provide an explosive binding device and a method for use for water conservancy and hydropower blasting. The present invention has the advantages of ensuring good binding effect and high binding efficiency.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0028] Embodiment. Explosive binding device for water conservancy and hydropower blasting, such as Figure 1As shown, it includes a front conveyor 1 and a rear conveyor 2, both of which are belt conveyors. The distance between the front conveyor 1 and the rear conveyor 2 is about twice the length of the explosive 26. A binding mechanism 3 is provided between the front conveyor 1 and the rear conveyor 2. The feeding end of the front conveyor 1 forms a loading area 4 for a long rod 27. A loading mechanism 5 is provided on the rear side of the loading area 4. The discharging end of the loading mechanism 5 is located above the rear conveyor 2. The loading mechanism 5 is used to transport the explosives 26 one by one to the front conveyor 1.

[0029] The tying mechanism 3 includes a bracket 6, which is fixed to the ground or to the frames of the front conveyor 1 and the rear conveyor 2. A circular ring seat 8 is provided on one side of the bracket 6, and a plurality of evenly distributed teeth are provided on the inner side of the circular ring seat 8, so that the circular ring seat 9 forms a gear ring. A first motor 21 is provided on the bracket 6, and a gear 22 matching the teeth is provided at the output end of the first motor 21. The first motor 21 drives the circular ring seat 8 to rotate through the gear 22.

[0030] Three rollers 7 are evenly distributed on the outside of the ring seat 8. An annular groove matching the rollers 7 is provided on the outer circumference of the ring seat 8. The roller shaft of the roller 7 is fixed to the bracket 6, and the rotating part of the roller 7 rotates around the roller shaft. The three rollers 7 ensure that the ring seat 8 will not be displaced in the axial and radial directions and can only perform rotational motion.

[0031] The circular seat 8 is provided with a mounting mechanism for the adhesive tape roll. The mounting mechanism comprises a sleeve 9 rotatably connected to the circular seat 8, the inner side end of the sleeve 9 radially extends outward to form a protrusion, and the outer side end of the sleeve 9 is provided with a baffle 10, which is threadedly connected to the sleeve 9. A first shaft 11 is provided on the axis of the sleeve 9, the first shaft 11 is rotatably connected to the sleeve 9, a second shaft 12 is provided between the first shaft 11 and the circular seat 8, the second shaft 12 is fixed to the circular seat 8, the second shaft 12 is hinged to the first shaft 11, and a plane is established with the axis of the circular seat 8 and the axis of the second shaft 12, and the hinge axis of the second shaft 12 and the first shaft 11 is perpendicular to the plane, so that the sleeve 9 can rotate inward, and a spring 13 is provided between the first shaft 11 and the circular seat 8, and when the sleeve 9 is not subjected to force, the spring 13 keeps the first shaft 11 and the second shaft 12 coaxial. After removing the baffle 10, put the tape roll (large roll of electrical tape) onto the sleeve 9, and then put the baffle 10 back to complete the installation of the tape roll. The width of the tape on the tape roll should not be too large, otherwise the disengagement force will be too large and will give the long rod 27 a greater resistance to movement. If the width is too small, it is easy to be pulled and deformed. A width of 2 cm is more appropriate.

[0032] Both sides of the conveying surface of the front conveyor 1 and the conveying surface of the rear conveyor 2 are provided with blocking plates 14, which are fixed to the frame of the front conveyor 1 or the rear conveyor 2, and a channel is formed between the blocking plates 14 on both sides, the channel is located on the axis of the circular ring seat 8, and the width of the channel matches the diameter of the explosive 26. The blocking plates 14 are used to prevent the long rod 27 and the explosive 26 from moving laterally and falling out.

[0033] The feeding mechanism 5 includes an inclined slide plate 15, a shelf connected to the ground is provided at the bottom of the slide plate 15, a feed hopper 23 with a square cross-section is provided at the upper end of the slide plate 15, and the lower end of the feed hopper 23 is a flat outlet, and the outlet width matches the diameter of the explosive 26. The lower end of the slide plate 15 is located above the front conveyor 1, and a feed roller 16 located on the upper side of the slide plate 15 is provided between the front conveyor 1 and the feed hopper 23. The feed roller 16 is provided with a plurality of arc notches 17. A second motor 18 with an output end connected to the feed roller 16 is provided on one side of the slide plate 15, and the second motor 18 is fixed to the shelf at the bottom of the slide plate 15.

[0034] The explosive binding device also includes a control system, which includes a controller 25. The front conveyor 1, the rear conveyor 2, the first motor 21 and the second motor 18 are all connected to the controller 25. The controller 25 is connected with a button 19 and a sensor 20. The sensor 20 is arranged between the front conveyor 1 and the rear conveyor 2 and can be fixed to the bracket 6. The sensor 20 can be a rotatable distance sensor, etc. As long as it can detect whether there is explosive 26 at the position of the long rod 27 pointed to by the sensor 20, skilled technicians can select the corresponding sensor model according to common sense.

[0035] A glue dispensing machine 24 connected to a controller 25 is provided between the feeding area 4 and the feeding mechanism 5. The glue dispensing machine 24 is a glue dispensing machine dedicated to quick-drying glue and is an existing device. The glue dispensing head on the glue dispensing machine can be raised and lowered.

[0036] Usage: 1) Pile the explosive 26 into the feed hopper 23, and note that the length direction of the explosive 26 is perpendicular to the length direction of the slide plate 15.

[0037] 2) Place the long rods 27 in the loading area 4 in sequence, and the long rods 27 cannot overlap and the distance between them should be kept below 1 cm. The long rods 27 are formed by split bamboo pieces, with a circular arc cross section and a width 1-2 mm less than the width between the two side baffles 14. A detonating cord needs to be placed on each long rod 27.

[0038] After each long rod 27 and detonating cord are placed, button 19 is pressed once and controller 25 receives a signal. Each time controller 25 receives a signal, front conveyor 1 and rear conveyor 2 are started simultaneously for a period of time with the same conveying speeds. During this period of time, the moving stroke of long rod 27 is required to be substantially equal to the length of long rod 27 itself.

[0039] Each time the controller 25 receives a signal, it periodically starts the second motor 18 for multiple times. Each time the second motor 18 is started, the feed roller 16 rotates a certain angle, which allows only one explosive 26 to pass through the feed roller 16 and slide to the front conveyor 1, while the remaining explosives 26 are blocked by the feed roller 16 and cannot continue to slide down. Of course, the second motor 18 can also rotate continuously for a period of time, and the speed of continuous rotation should be relatively slow, so that the delivered explosives 26 form a certain interval on the long rod 27.

[0040] Each time the controller 25 receives a signal, the glue dispenser 24 periodically performs glue dispensing, and the frequency of the glue dispensing matches the starting frequency of the second motor 18, which is an integer multiple, so that the sliding explosive 26 is glued to the long rod 27. The best option is that the front and rear ends and the middle of the explosive 26 are glued to the long rod 27 by three-point glue, which is only a preliminary fixation. When the long rod 27 passes through the slide plate 15, multiple explosives 26 are evenly fixed on the long rod 27 to form a whole.

[0041] Every time the controller 25 receives a signal, it starts the first motor 21 for a period of time. The starting time of the first motor 21 is the same as the starting time of the front and rear conveyors, so that the binding mechanism 3 only works during the movement of the long rod 27. Once the long rod 27 stops moving, the binding mechanism 3 also stops working, avoiding waste of tape and reducing the binding cost.

[0042] The long rod 27 moves at a constant speed from the front conveyor 1 to the rear conveyor 2. When passing through the binding mechanism 3, it is tied with tape. The tape is wound with a large pitch on the position of the long rod 27 where there is no explosive 26 to reduce the amount of tape used. It is wound with a small pitch on the position where there is explosive 26 to better protect the explosive 26 and ensure that the explosive 26 and the long rod 27 are reliably fixed.

[0043] The tape between the front and rear long rods 27 is cut off after the next long rod 27 is also moved to the rear conveyor 2. This also means that when tying explosives 26 to multiple long rods 27, the tape on the tying mechanism 3 only needs to be manually fixed once at the front end of the first long rod 27, and there is no need to manually operate the tape later.

[0044] The working principle of the binding mechanism 3 is as follows: the first motor 21 drives the gear 22 to rotate, the gear 22 drives the annular seat 8 to rotate, the annular seat 8 drives the tape roll to rotate around the long rod 27 through the sleeve 9, so that the tape is spirally wound on the long rod 27. When the explosive 26 is not detected by the sensor 20, the controller 25 makes the first motor 21 rotate at a low speed, and the tape is wound on the long rod 27 with a large pitch. When the explosive 26 is detected by the sensor 20, the controller 25 makes the first motor 21 rotate at a high speed, and the tape is wound on the long rod 27 with a small pitch.

[0045] When the tape is wound on the long rod 27 with a large pitch, the long rod 27 gives a large axial traction to the tape roll, and there is a small angle between the drawn tape and the long rod 27. At this time, since the first axis 11 and the second axis 12 are hinged, the sleeve 9 will rotate, so that the tape roll and the drawn tape are basically maintained in the same plane, avoiding the drawn tape from twisting and self-adhesion, thereby improving the binding effect.
