Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blasting, in particular to a bamboo strip connecting mechanism for detonator propulsion. BACKGROUND

[0002] In blasting engineering, the detonator is the main initiation material, and the role of the detonator is to detonate explosives. After the target object is drilled, the detonator needs to be safely delivered to the center of the target object and then detonated, so as to achieve the optimal blasting effect.

[0003] In actual blasting engineering, when drilling holes in the target object using a drill or other drilling tools, the hardness of the target object is not uniform, which can easily cause the drilled hole path to bend.

[0004] The existing detonator propulsion device can only propel the detonator along a straight line, and when the length of the target object center cannot be detected, the appropriate length of the detonator propulsion device cannot be selected. SUMMARY

[0005] The purpose of the present application is to provide a bamboo strip connecting mechanism for detonator propulsion, which aims to solve the problems of the existing detonator that cannot propel the curved path hole and cannot select the length of the propulsion device.

[0006] To achieve the above purpose, the present application provides a bamboo strip connecting mechanism for detonator propulsion, which comprises a pipe body, two side plates, two convex blocks, two guide rails, two elastic sheets and two wedge blocks, the two side plates are respectively fixedly connected with the two pipe bodies and are respectively located on one side of the pipe body, the two convex blocks are respectively fixedly connected with the two side plates and are respectively located on one side of the two side plates, the two guide rails are respectively fixedly connected with the side plates and are respectively located on one side of the side plates, the two elastic sheets are respectively fixedly connected with the pipe body and are respectively located on one side of the pipe body, and the two wedge blocks are respectively fixedly connected with the two elastic sheets and are respectively located on one side of the two elastic sheets.

[0007] Among them, the pipe body has a plurality of first sliding holes, a plurality of second sliding holes and a plurality of third sliding holes, and the plurality of first sliding holes, the plurality of second sliding holes and the plurality of third sliding holes are respectively located on one side of the pipe body.

[0008] Among them, the bamboo strip connecting mechanism for detonator propulsion further comprises two convex blocks, and the two convex blocks are respectively fixedly connected with the pipe body and are respectively located on one side of the pipe body.

[0009] Among them, the pipe body has two sliding grooves, and the two sliding grooves are respectively located on one side of the pipe body away from the convex block.

[0010] Two fixing assemblies are arranged on one side of the side plates.

[0011] The fixing assembly comprises a mounting frame, a rotating member, a bidirectional screw rod, two transmission cylinders, vertical rods and two clamping plates. The mounting frame is fixedly connected with the side plates and located on one side of the side plates. The rotating member is arranged on one side of the mounting frame. The bidirectional screw rod is rotatably connected with the mounting frame and connected with the rotating member. The two transmission cylinders are threadedly connected with the bidirectional screw rod and located on one side of the bidirectional screw rod. The two vertical rods are fixedly connected with the two transmission cylinders and located on one side of the transmission cylinder. The two clamping plates are fixedly connected with the two vertical rods and slidably connected with the mounting frame.

[0012] The fixing assembly further comprises two sliding blocks which are fixedly connected with the two transmission cylinders and slidably connected with the mounting frame.

[0013] The pipe body provides mounting conditions for the two side plates and the two elastic sheets. The two side plates provide mounting conditions for the two guide rails and the two convex blocks. The two convex blocks cooperate with the two guide rails to realize the connection of multiple connecting pieces. The rebound force of the two elastic sheets cooperates with the two wedge-shaped blocks to limit the bamboo strips inserted into the pipe body, preventing the bamboo strips from moving out of the pipe body. When connecting two bamboo strips by using the connecting pieces, the thickness of the bamboo strips needs to be less than the height difference between the upper and lower sides of the pipe body. When the bamboo strip is inserted from the tail of the pipe body, the triangular block of the wedge-shaped block is wedge-shaped, and the bamboo strip can be slowly inserted into the through hole. The wedge-shaped block is expanded to the outside of the pipe body under the extrusion of the bamboo strip, and the elastic sheet clamps the bamboo strip by the elastic effect. The present application uses bamboo strips which are not easy to generate static electricity, and the connecting pieces are relatively safe for connecting bamboo strips to push the detonator. The connecting pieces can be connected in an upper-lower overlapping manner and a left-right end manner. The rigidity of the bamboo strips is increased during pushing, and the bamboo strips are not easy to break. According to the needs of blasting engineering, multiple connecting pieces can be used to connect the bamboo strips to the required length. The bamboo strips can also be connected in a circular ring or an upper-lower overlapping mortise and tenon structure to increase the rigidity of the bamboo strips, thereby solving the problems that the existing detonator cannot be pushed along a curved path blast hole and the length of the pushing device cannot be selected.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] Please see Figs. 1-2 This invention provides a bamboo strip connecting mechanism for detonator propulsion, comprising a tube body 1, two side plates 2, two convex blocks 3, two guide rails 4, two elastic plates 5, and two wedge blocks 6. The two side plates 2 are respectively fixedly connected to the two tube bodies 1 and are respectively located on one side of the tube body 1. The two convex blocks 3 are respectively fixedly connected to the two side plates 2 and are respectively located on one side of the two side plates 2. The two guide rails 4 are respectively fixedly connected to the side plates 2 and are respectively located on one side of the side plates 2. The two elastic plates 5 are respectively fixedly connected to the tube body 1 and are respectively located on one side of the tube body 1. The two wedge blocks 6 are respectively fixedly connected to the two elastic plates 5 and are respectively located on one side of the two elastic plates 5.

[0021] In this embodiment, the tube 1 provides installation conditions for the two side plates 2 and the two elastic pieces 5. The two side plates 2 provide installation conditions for the two guide rails 4 and the two convex blocks 3. The two convex blocks 3, in conjunction with the two guide rails 4, can achieve the connection of multiple connectors. The rebound force of the two elastic pieces 5, in conjunction with the two wedge blocks 6, can limit the bamboo strips inserted into the tube 1, preventing the bamboo strips from moving out of the tube 1. When connecting two bamboo strips with connectors, the thickness of the bamboo strips needs to be less than the height difference between the upper and lower sides of the tube 1. When the bamboo strip is inserted from the tail of the tube 1, the triangular block of the wedge block 6 has a wedge-shaped hypotenuse, allowing the bamboo strip to be slowly inserted into the through hole. The wedge block 6 is squeezed by the bamboo strip and expands outward from the tube 1. The elasticity of the elastic piece 5 will clamp the bamboo strip. This invention uses bamboo strips that are less prone to static electricity, making the connection of the bamboo strips to the detonator safer. The connectors can be stacked vertically or connected at both ends, increasing the rigidity of the bamboo strips during advancement and making them less prone to breakage. Multiple connectors can be used to connect bamboo strips to the required length according to the needs of blasting projects. Alternatively, the bamboo strips can be connected in a circular or overlapping mortise and tenon structure to increase their rigidity. This solves the problems of existing detonators being unable to advance into curved blast holes and being unable to select the length of the advancement device.

[0022] Furthermore, the tube body 1 has a plurality of first sliding holes 7, a plurality of second sliding holes 8 and a plurality of third sliding holes 9, the plurality of first sliding holes 7, the plurality of second sliding holes 8 and the plurality of third sliding holes 9 being located on one side of the tube body 1 respectively.

[0023] In this embodiment, there are sliding holes No. 1, No. 2, and No. 3 on the two side walls of the tube body 1. Sliding holes No. 2 and No. 3 are symmetrically distributed at intervals from the front end to the rear end of the tube body 1. The center lines of sliding holes No. 2 and No. 3 coincide with the center line of the elastic sheet 5. Sliding holes No. 1, No. 2, and No. 3, the protrusion at the upper end of the tube body 1, and the groove at the bottom end are all symmetrical about the left and right ends. In addition, sliding holes No. 1, No. 2, and No. 3 are symmetrical about the radial ends of the tube body 1. After determining the position of the first bamboo strip, a slider 19 is installed at the No. 2 sliding hole to fix it on both sides of the bamboo tail, so that the bamboo strip is fixed better. When the second bamboo strip is inserted into the same connector, the part extending outward from the through hole connects with the tail of the first bamboo strip, and a slider 19 is installed at the No. 3 sliding hole to better fix the head of the second bamboo strip, and so on.

[0024] Furthermore, the bamboo strip connecting mechanism for detonator propulsion also includes two protrusions 10, which are fixedly connected to the tube body 1 and located on one side of the tube body 1 respectively.

[0025] In this embodiment, multiple connectors can be longitudinally connected by the two protrusions 10 and the two grooves 11.

[0026] Furthermore, the tube body 1 has two grooves 11, which are located on the side of the tube body 1 away from the protrusion 10.

[0027] In this embodiment, multiple connectors can be longitudinally connected by the two grooves 11 and the two protrusions 10.

[0028] Furthermore, the bamboo strip connecting mechanism for detonator propulsion also includes two fixing components 12, which are respectively disposed on one side of the two side plates 2.

[0029] In this embodiment, the bamboo strips inserted into the tube 1 can be fixed by the two fixing components 12, thereby improving the stability of the bamboo strips.

[0030] Furthermore, the fixing assembly 12 includes a mounting frame 13, a rotating component 14, a bidirectional screw 15, two transmission cylinders 16, vertical rods 17, and two clamping plates 18. The mounting frame 13 is fixedly connected to the side plate 2 and is located on one side of the side plate 2. The rotating component 14 is disposed on one side of the mounting frame 13. The bidirectional screw 15 is rotatably connected to the mounting frame 13 and connected to the rotating component 14. The two transmission cylinders 16 are threadedly connected to the bidirectional screw 15 and are located on one side of the two bidirectional screws 15 respectively. The two vertical rods 17 are fixedly connected to the two transmission cylinders 16 and are located on one side of the two transmission cylinders 16 respectively. The two clamping plates 18 are fixedly connected to the two vertical rods 17 respectively and are slidably connected to the mounting frame 13 respectively.

[0031] In this embodiment, the mounting frame 13 provides installation conditions for the rotating component 14 and the bidirectional screw 15. Rotating the rotating component 14 causes the bidirectional screw 15 to rotate, which in turn causes the two transmission cylinders 16 to move closer together. The two transmission cylinders 16 then cause the two vertical rods 17 to move closer together, and the two vertical rods 17 cause the two clamping plates 18 to move closer together until the two clamping plates 18 contact the bamboo strip and the tube body 1, clamping the bamboo strip and thus fixing it, thereby improving the stability of the bamboo strip.

[0032] Furthermore, the fixing component 12 also includes two sliders 19, which are fixedly connected to the two transmission cylinders 16 and slidably connected to the mounting frame 13 respectively.

[0033] In this embodiment, when the two transmission cylinders 16 move, they drive the two sliders 19 to slide within the mounting frame 13. The two sliders 19 guide the two transmission cylinders 16, thereby improving the stability of the two transmission cylinders 16 during movement.

[0034] Furthermore, the rotating component 14 includes a turntable 20, a locking block 21, a pull rod 22, and a spring 23. The turntable 20 is fixedly connected to the bidirectional screw 15 and rotatably connected to the mounting frame 13. The pull rod 22 is fixedly connected to the locking block 21 and is located on one side of the locking block 21. The locking block 21 is slidably connected to the mounting frame 13 and is located inside the mounting frame 13. The spring 23 is fixedly connected to the locking block 21 and is also fixedly connected to the mounting frame 13, both located between the locking block 21 and the mounting frame 13.

[0035] In this embodiment, the turntable 20 has multiple mating holes. Rotating the turntable 20 can drive the bidirectional screw 15 to rotate. When it is necessary to rotate the turntable 20, the pull rod 22 is pulled away from the turntable 20. The pull rod 22 drives the mating block 21 to move away from the turntable 20. When the mating block 21 is completely away from the mating hole, the turntable 20 can be rotated. When it is not necessary to rotate the turntable 20, the spring force of the spring 23 can spring the mating block 21 into the corresponding mating hole. The mating block 21 limits the turntable 20 and prevents the turntable 20 from rotating due to external forces.

[0036] Furthermore, the rotating component 14 also includes an anti-slip sleeve 24, which is fixedly connected to the pull rod 22 and located around the pull rod 22.

[0037] In this embodiment, the anti-slip sleeve 24 can increase the friction of the pull rod 22 and prevent slippage when the pull rod 22 is pulled.

[0038] The above-disclosed embodiments are merely preferred embodiments of the bamboo strip connection mechanism for detonator propulsion according to the present invention. Of course, they should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
