Description

Technical Field

[0001] This utility model relates to the field of blast hole plugging technology, specifically a blast hole plugging component that prevents detachment. Background Technology

[0002] Blasting is a technique that utilizes the compression, loosening, destruction, throwing, and killing effects produced by the explosion of explosives in air, water, soil, rock, or other objects to achieve a desired objective. There are various blasting methods, among which the drilling method is commonly used for blasting mountains. This involves drilling a hole, inserting a blasting tube and explosives, securing the blasting tube, and then igniting it to detonate. However, the blasting tube often loosens due to the massive shockwave generated by the explosion, sometimes even producing a "skyrocket" effect. This causes a significant loss of the explosive's energy, resulting in poor blasting effectiveness and the possibility of it flying out and causing accidents. This is highly detrimental to the acceptance of blasting results, thus necessitating the use of a blasting hole plugging device.

[0003] In existing technologies, such as the blasting hole sealing device for earthwork engineering disclosed in CN221882363U, a mounting sleeve is provided. An end block is located below the mounting sleeve, and a telescopic rubber sleeve connects the end block to the mounting sleeve. An adjusting component is located in the middle of the end block to move it along the axis of the mounting sleeve. Four through slots are evenly distributed on the mounting sleeve, penetrating its interior. The device uses a supporting component to simultaneously expand the four supporting arms outwards and abut against the hole wall, thus fixing the mounting sleeve in the hole. Subsequently, the adjusting component moves the end block towards the mounting sleeve, gradually increasing the diameter of the telescopic rubber sleeve until the blasting hole is completely sealed. This device can seal holes of different diameters.

[0004] The existing sealing device uses a support assembly to drive four support arms to expand outward simultaneously and abut against the borehole wall, thereby fixing the mounting sleeve in the borehole. Then, an adjustment assembly moves the end block towards the mounting sleeve, gradually increasing the diameter of the telescopic rubber sleeve until the blast hole is completely sealed. It can seal holes of different diameters, but it lacks an anti-fall-off structure, resulting in a large amount of explosive energy leaking from the borehole opening, insufficient blasting power, incomplete rock fragmentation, and failure to achieve the designed blasting effect. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] Given that the existing technologies mentioned above lack an anti-fall-off structure, resulting in a large amount of explosive energy leaking from the orifice, insufficient blasting power, incomplete rock fragmentation, and failure to achieve the designed blasting effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A plugging assembly for preventing detachment during blasting includes: a plugging plate, a fixed bearing, a lead screw, and a handle; the fixed bearing is embedded in the upper surface of the plugging plate, the lead screw is connected to the inner wall of the fixed bearing, and the handle is welded and fixed to the upper surface of the lead screw; the assembly also includes: The device includes a fixing component, a reinforcing component, and a buffer component; the fixing component is disposed outside the lead screw, the reinforcing component is disposed outside the sealing plate, and the buffer component is disposed at the lower end of the sealing plate.

[0008] As a further embodiment of this utility model: the fixing component includes: a fixing member, a guide rod, a slider, a hinge member, a hinge rod, a connecting member, and a fixing plate. The fixing member is placed outside the lead screw, and the guide rod, which is welded to the sealing plate, is fixed inside the fixing member.

[0009] As a further improvement of this utility model: both ends of the guide rod are slidably connected to sliders, and a hinge is welded and fixed to one side of the slider.

[0010] As a further embodiment of this utility model: a hinge rod is hinged inside the hinge member, a connector is hinged at the end of the hinge rod, and a fixing plate is welded and fixed on one side of the connector.

[0011] As a further embodiment of this utility model: the reinforcing component includes: a reinforcing sleeve, a connecting sleeve, a fixing screw, and a connecting hole. The reinforcing sleeve is installed on the outside of the sealing plate, and the connecting sleeve is fitted on the outer surface of the reinforcing sleeve.

[0012] As a further improvement of this utility model: a fixing screw is installed on the outer wall of the connecting sleeve, and the end of the fixing screw is threadedly connected to a connecting hole opened on the reinforcing sleeve.

[0013] As a further embodiment of this utility model: the buffer assembly includes: a mounting cavity, a limiting plate, a buffer spring, a connecting rod, and a buffer plate. The mounting cavity is located at the lower end of the sealing plate, and the limiting plate is slidably connected inside the mounting cavity.

[0014] As a further embodiment of this utility model: a buffer spring is abutted on the upper surface of the limiting plate, a connecting rod is welded and fixed on the lower surface of the limiting plate, and a buffer plate is fixed on the lower surface of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses the guide rod on the fixing component to synchronously drive the two sliders to move relative to each other, thereby driving the hinge component to move. With the cooperation of the hinge rod, the hinge rod can push and pull the connecting component to move horizontally when it moves, thereby driving the fixing plate, so that the outer surface of the fixing plate is tightly attached to the inner wall of the blast hole, which can limit and fix the component, thereby effectively reducing the possibility of the component falling off.

[0016] 2. The present invention utilizes the mounting cavity at the bottom of the sealing plate. When the blasting hole is blasted, the impact force generated will push the buffer plate to move. The buffer plate will drive the connecting rod to move, causing the limiting plate to push the buffer spring in the mounting cavity to compress. This can play a certain buffering role, reduce the damage of the impact force to the component, and reduce the displacement of the device caused by the impact force. Attached Figure Description

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1: Please see Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an anti-fall-off blast hole sealing assembly, including: a sealing plate 1, a fixed bearing 2, a lead screw 3, and a handle 4; the fixed bearing 2 is embedded in the upper surface of the sealing plate 1, the lead screw 3 is connected to the inner wall of the fixed bearing 2, and the handle 4 is welded and fixed to the upper surface of the lead screw 3, and also includes: The assembly includes a fixing component, a reinforcing component, and a buffer component. The fixing component is located outside the lead screw 3, the reinforcing component is located outside the sealing plate 1, and the buffer component is located at the lower end of the sealing plate 1.

[0023] Specifically, the fixing components include: a fixing member 5, a guide rod 51, a slider 52, a hinge 53, a hinge rod 54, a connector 55, and a fixing plate 56. The fixing member 5 is placed outside the lead screw 3. Inside the fixing member 5, a guide rod 51 that is welded to the sealing plate 1 is fixed. Both ends of the guide rod 51 are slidably connected to sliders 52. A hinge 53 is welded to one side of the slider 52.

[0024] Furthermore, turning the handle 4 on the lead screw 3, with the cooperation of the fixed bearing 2, can ensure the stability of the rotation of the lead screw 3. The lead screw 3 is welded together from two screws with different screw directions, and both screws have a slider 52 threadedly connected to their outer surfaces. This allows the lead screw 3 to rotate synchronously with the two sliders 52 under the action of the guide rod 51 on the fixed part 5.

[0025] Specifically, a hinge rod 54 is hinged inside the hinge member 53, and a connector 55 is hinged at the end of the hinge rod 54. A fixing plate 56 is welded and fixed to one side of the connector 55.

[0026] Furthermore, with the cooperation of the hinge rod 54, the hinge rod 54 can push and pull the connector 55 to move horizontally when it moves, thereby driving the fixing plate 56, so that the outer surface of the fixing plate 56 is tightly attached to the inner wall of the blast hole, which can limit and fix the component.

[0027] In use, the sealing plate 1 is placed in a suitable position, and the handle 4 on the screw 3 is turned. With the cooperation of the fixed bearing 2, the stability of the screw 3 rotation can be ensured. The screw 3 is welded from two screws with different screw directions, and the outer surfaces of the two screws are threaded with sliders 52. When the screw 3 rotates, under the action of the guide rod 51 on the fixing part 5, the two sliders 52 can be driven to move relative to each other in sync, thereby driving the hinge 53 to move. With the cooperation of the hinge rod 54, the hinge rod 54 can push and pull the connecting part 55 to move horizontally when it moves, thereby driving the fixing plate 56, so that the outer surface of the fixing plate 56 is tightly attached to the inner wall of the blast hole. This can limit and fix the component, thereby effectively reducing the possibility of the component falling off.

[0028] In summary, when this anti-detachment blast hole sealing assembly is in use, the guide rod 51 on the fixing member 5 can synchronously drive the two sliders 52 to move relative to each other, thereby driving the hinge member 53 to move. With the cooperation of the hinge rod 54, the hinge rod 54 can push and pull the connecting member 55 to move horizontally, thereby driving the fixing plate 56, so that the outer surface of the fixing plate 56 is tightly attached to the inner wall of the blast hole, which can limit and fix the assembly, thereby effectively reducing the possibility of the assembly falling off.

[0029] Example 2: Please see Figures 1-5 This is the second embodiment of the present utility model.

[0030] Specifically, the reinforcing components include: a reinforcing sleeve 6, a connecting sleeve 61, a fixing screw 62, and a connecting hole 63. The reinforcing sleeve 6 is installed on the outside of the sealing plate 1. The connecting sleeve 61 is fitted on the outer surface of the reinforcing sleeve 6. The fixing screw 62 is installed on the outer wall of the connecting sleeve 61. The end of the fixing screw 62 is threaded to the connecting hole 63 opened on the reinforcing sleeve 6.

[0031] Furthermore, tighten the fixing screw 62 so that the fixing screw 62 is threaded into the connecting hole 63 on the reinforcing sleeve 6, thereby fixing the connecting sleeve 61. This can increase the overall diameter of the sealing plate 1.

[0032] Specifically, the buffer assembly includes: a mounting cavity 7, a limiting plate 71, a buffer spring 72, a connecting rod 73, and a buffer plate 74. The mounting cavity 7 is located at the lower end of the sealing plate 1. The limiting plate 71 is slidably connected inside the mounting cavity 7. The upper surface of the limiting plate 71 abuts against the buffer spring 72. The connecting rod 73 is welded and fixed to the lower surface of the limiting plate 71. The buffer plate 74 is fixed to the lower surface of the connecting rod 73.

[0033] Furthermore, the impact force generated when the blast hole is blasted will push the buffer plate 74 to move. The buffer plate 74 drives the connecting rod 73 to move, which causes the limiting plate 71 to push the buffer spring 72 in the mounting cavity 7 to compress, which can play a certain buffering role.

[0034] In use, the connecting sleeve 61 can be fitted onto the outer wall of the reinforcing sleeve 6 provided on the sealing plate 1 through the reinforcing sleeve 6. Then, the fixing screw 62 is tightened so that the fixing screw 62 is threadedly connected to the connecting hole 63 on the reinforcing sleeve 6, thereby fixing the connecting sleeve 61. This can lengthen the overall diameter of the sealing plate 1, making it convenient to seal blast holes of different diameters. The sealing plate 1 is placed in the blast hole, so that the outer surface of the connecting sleeve 61 is tightly fitted to the inner wall of the blast hole. Through the mounting cavity 7 provided at the bottom of the sealing plate 1, the impact force generated when the blast hole is blasted will push the buffer plate 74 to move. The buffer plate 74 drives the connecting rod 73 to move, so that the limiting plate 71 pushes the buffer spring 72 in the mounting cavity 7 to compress, which can play a certain buffering role, reduce the damage of the impact force to the component, and reduce the displacement of the device caused by the impact force.

[0035] In summary, the impact force generated when the blast hole is blasted through the mounting cavity 7 at the bottom of the sealing plate 1 will push the buffer plate 74 to move. The buffer plate 74 will drive the connecting rod 73 to move, so that the limiting plate 71 will push the buffer spring 72 in the mounting cavity 7 to compress, which can play a certain buffering role, reduce the damage of the impact force to the component, and reduce the displacement of the device caused by the impact force.
