Description

Technical Field

[0001] This utility model relates to the technical field of spacers for mine blasting, and specifically to a spacer for mine blasting. Background Technology

[0002] Blasting spacers generally refer to devices used to separate explosive charges during blasting operations. These can be gas spacers or other types of spacers. Among them, gas spacers are widely used in blasting operations due to their unique advantages.

[0003] The current announcement number CN218349327U discloses a spacer for mine blasting, including a top cover, an air pipe at the top of the top cover, an air bag below the top cover, the air pipe penetrating the top cover and inserted into the air bag, the air pipe being fixedly connected to the top cover, branch pipes being symmetrically fixedly installed on both sides of the air pipe, the air bag being fixedly connected to the air pipe, a first protective shell being provided on the outside of the air bag, and a second protective shell being provided at the bottom of the air bag. This utility model introduces gas through the air pipe and branch pipes, and uses rubber convex balls to provide a first-level buffering effect. The first protective shell, the second protective shell, and the top cover can all deform with the deformation of the air bag, and elastic ropes are provided between the first protective shell, the second protective shell, and the top cover, which enhances the deformation effect and facilitates installation.

[0004] To address the protection issue, existing technology uses elastic ropes, which enhance deformation and are easy to install. However, problems still arise where the elasticity fails to support the guard plate during descent, and the position of the elastic ropes cannot be controlled. This leads to the elastic ropes scraping during descent and failing to reach the designated area. Utility Model Content

[0005] The purpose of this utility model is to provide a spacer for mine blasting to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A spacer for mine blasting includes a pull rope, a deformation unit at one end of the pull rope, a protective unit inside the deformation unit, an airbag unit on the bottom side of the deformation unit, and a buffer unit on the bottom side of the deformation unit.

[0008] The deformation unit includes a fixed block, which is fixedly connected to one end of the pull rope. A limit box is fixedly connected to one side of the fixed block. A limit groove is opened inside the limit box. A buffer telescopic rod is provided inside the fixed block. A spring is sleeved on the outside of the buffer telescopic rod.

[0009] A further improvement of the present invention is that the protective unit includes a support rod, which is fixedly connected to one end of a buffer telescopic rod, one side of the support rod is fixedly connected to one end of a spring, and a rubber block is fixedly connected to one side of the support rod.

[0010] By adopting the above technical solution, the setting of support rods and rubber blocks helps to prevent the inner wall of the rupture hole from scratching the internal airbag during the descent.

[0011] A further improvement of this utility model is that a buffer block is fixedly connected to one side of the rubber block.

[0012] By adopting the above technical solution and setting up a buffer block, air leakage during the inflation process of the airbag is prevented, thereby protecting the airbag.

[0013] A further improvement of the present invention is that the airbag unit includes an airbag, the airbag is fixedly connected to one side of the fixing block, the airbag has an air outlet, and a sealing plug is fitted inside the air outlet.

[0014] By adopting the above technical solution, the airbag, air vent, and sealing plug are designed to facilitate the expulsion of air from inside the airbag before use, which is convenient for subsequent descent and placement.

[0015] A further improvement of this utility model is that: an air tank is fixedly connected inside the airbag, a traction rope is provided on one side of the air tank, and the inner side of the traction rope is slidably connected inside the fixed block.

[0016] By adopting the above technical solution, the installation of the gas tank and traction rope facilitates the supply of gas for the inflation of the airbag.

[0017] A further improvement of the present invention is that the buffer unit includes a limiting tube, the limiting tube is fixedly connected to the bottom surface of the fixing block, a second buffer telescopic rod is fixedly connected inside the limiting tube, a second spring is sleeved on the outside of the second buffer telescopic rod, and one end of the second spring is fixedly connected to one side inside the limiting tube.

[0018] By adopting the above technical solution, the setting of the limiting tube, the second buffer telescopic rod and the second spring can effectively buffer the impact force generated by the explosion. At the same time, the counterweight and the storage tray can be recycled and reused, saving costs.

[0019] A further improvement of the present invention is that: one end of the second spring is fixedly connected to a counterweight, the inside of the counterweight is slidably connected to the inside of the limiting tube, and one end of the limiting tube is slidably connected to a storage tray.

[0020] By adopting the above technical solution, the use of counterweights and a storage tray facilitates the effect of providing counterweight for the device's descent.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a spacer for mine blasting. Through the arrangement of a fixed block, a limiting box, a limiting groove, a buffer telescopic rod, and a spring, it facilitates the support of the protective plate and protects the airbag, while avoiding the problem of airbag rupture during expansion and descent. The setting of the support rod and rubber block helps to prevent the inner wall of the blast hole from scratching the internal airbag during descent. The arrangement of the airbag, air outlet, and sealing plug facilitates the discharge of air from the airbag before use, which is convenient for subsequent descent and placement.

[0023] 2. This utility model provides a spacer for mine blasting. By setting up a limiting tube, a second buffer telescopic rod and a second spring, it is easy to buffer the impact force generated by the explosion. At the same time, the counterweight and the storage tray can be recycled and reused, saving costs.

[0030] The present invention will be further described in detail below with reference to embodiments:

[0031] Example 1

[0032] like Figure 1-5 As shown, this utility model provides a spacer for mine blasting, including a pull rope 1, a deformation unit 2 at one end of the pull rope 1, a protective unit 3 inside the deformation unit 2, an airbag unit 4 at the bottom of the deformation unit 2, and a buffer unit 5 at the bottom of the deformation unit 2. The deformation unit 2 includes a fixing block 21, which is fixedly connected to one end of the pull rope 1. A limit box 22 is fixedly connected to one side of the fixing block 21. A limit groove 23 is formed inside the limit box 22. A buffer telescopic rod 24 is provided inside the fixing block 21. The side sleeve is equipped with a spring 25. The protective unit 3 includes a support rod 31, which is fixedly connected to one end of the buffer telescopic rod 24. One side of the support rod 31 is fixedly connected to one end of the spring 25. A rubber block 32 is fixedly connected to one side of the support rod 31, and a buffer block 33 is fixedly connected to one side of the rubber block 32. The airbag 41 drives the support rod 31 to move under the limitation of the limiting groove 23. At the same time, the rubber block 32 contacts the inner wall of the explosion hole. Meanwhile, the support rod 31 drives the buffer telescopic rod 24 and the spring 25 to extend, thereby completing the spacing of the explosion hole.

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the airbag unit 4 includes an airbag 41, which is fixedly connected to one side of the fixing block 21. An air outlet 42 is provided inside the airbag 41, and a sealing plug 43 is sleeved inside the air outlet 42. An air tank 44 is fixedly connected inside the airbag 41, and a traction rope 45 is provided on one side of the air tank 44. The inner side of the traction rope 45 is slidably connected to the inside of the fixing block 21. By removing the sealing plug 43 from the air outlet 42, the gas inside the airbag 41 is discharged. Then, the device is placed inside the explosion hole by pulling the rope 1. Then, the device is released downward by pulling the rope 1. At the same time, the traction rope 45 and the pull rope 1 move simultaneously to the designated position. By pulling the traction rope 45, the air tank 44 is opened, and the air tank 44 delivers gas to the inside of the airbag 41, causing the airbag 41 to inflate.

[0035] Example 3

[0036] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the buffer unit 5 includes a limiting tube 51, which is fixedly connected to the bottom surface of the fixing block 21. A second buffer telescopic rod 52 is fixedly connected inside the limiting tube 51, and a second spring 53 is sleeved on the outside of the second buffer telescopic rod 52. One end of the second spring 53 is fixedly connected to one side of the inside of the limiting tube 51, and a counterweight 54 is fixedly connected to one end of the second spring 53. The counterweight 54 is slidably connected inside the limiting tube 51, and a storage tray 55 is slidably connected to one end of the limiting tube 51. During an explosion, the impact force generated by the explosion acts on one side of the storage tray 55. At the same time, the storage tray 55 pushes the counterweight 54 to move inside the limiting tube 51. Simultaneously, the counterweight 54 pushes the second spring 53 and the outer buffer telescopic rod 52 to buffer the impact force generated by the explosion, thereby protecting the counterweight 54 and the storage tray 55, and facilitating the subsequent recycling and reuse of the counterweight 54 and the storage tray 55.

[0037] The working principle of the spacer used for blasting in this mine will be explained in detail below.

[0038] like Figure 1-5 As shown, by removing the sealing plug 43 from the inside of the vent 42, the gas inside the airbag 41 is discharged. The sealing plug 43 is then installed inside 42. The device is then inserted into the vent via the pull rope 1, and subsequently released downwards via the pull rope 1. Simultaneously, the traction rope 45 moves along with the pull rope 1 to the designated position. Pulling the traction rope 45 opens the gas cylinder 44, which then delivers gas into the airbag 41, causing it to inflate. Simultaneously, the airbag 41 moves the support rod 31 within the limiting groove 23, while the rubber... Block 32 contacts the inner wall of the explosion hole, while the support rod 31 drives the buffer telescopic rod 24 and spring 25 to extend, thereby completing the separation of the explosion hole. At the same time, during the explosion, the impact force generated by the explosion acts on one side of the storage tray 55, and the storage tray 55 pushes the counterweight block 54 to move inside the limiting tube 51. Meanwhile, the counterweight block 54 pushes the spring 53 and the outer buffer telescopic rod 52 to buffer the impact force generated by the explosion, thereby protecting the counterweight block 54 and the storage tray 55, which is convenient for subsequent recycling and reuse of the counterweight block 54 and the storage tray 55.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
