Description

Technical Field

[0001] The present application relates to the technical field of rock blasting, and in particular to a safety device for static explosion. Background Art

[0002] At present, the so-called static blasting technology mainly refers to the use of static blasting agents to blast and excavate rocks or concrete. Due to the advantages of no noise, no dust, no flying stones, no toxic and harmful gases, no vibration, and no legal control during the construction process of using static crushing agents, it has been widely used in many projects around the world.

[0003] In the existing rock blasting, blasting agent is usually used. Explosive agent is a new type of crushing material. It is mixed with water to form a slurry and poured into the drilled hole of rock or concrete structure. It relies on the expansion pressure generated by its own hydration to safely crush the rock or concrete.

[0004] The above-mentioned prior art solutions have the following defects: in the process of mixing water and blasting agent into slurry and then pouring it into the borehole, there is a problem that the slurry undergoes chemical reaction and blasting, which may injure workers. Utility Model Content

[0005] In order to improve the safety of the process of mixing water and blasting agent into slurry and then pouring it into a borehole, the present application provides a safety device for static explosion.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A safety device for static explosion comprises a safety cover and a stirring device. The safety cover is arranged on a working surface, and is used to isolate a rock drilling area from a personnel operation area. The stirring device is located in the safety cover. The stirring device comprises a stirring barrel, a material guide pipe and a frame. The frame is fixedly connected to the working surface, and the stirring barrel is fixedly connected to the frame. A first feeding port and a second feeding port are arranged on the top wall of the stirring barrel. Water is injected into the stirring barrel through the first feeding port, and a blasting agent is injected into the stirring barrel through the second feeding port. The bottom wall of the stirring barrel is connected to the material guide pipe, and one end of the material guide pipe away from the stirring barrel is plugged into the borehole. The stirring device is used to stir the blasting agent and water into a slurry and then inject it into the borehole through the material guide pipe; a sealing device is arranged between the stirring barrel and the material guide pipe. When the stirring barrel is in a stirring state, the sealing device is used to block the stirring barrel and the material guide pipe; when the slurry in the stirring barrel is stirred, the sealing device is removed, and the stirring barrel and the material guide pipe are in a connected state.

[0008] By adopting the above scheme, a safety cover is first set up, and the safety cover isolates the area where water and blasting agent are mixed from personnel. Because a sealing device is set up, when water is injected into the mixing barrel through the first feed port and the blasting agent is injected into the mixing barrel through the second feed port, the sealing device is used to seal the mixing barrel and the guide pipe until a certain proportion of water and blasting agent are injected into the mixing barrel, and the water and the blasting agent are stirred to form a slurry, and then the sealing device is opened to make the mixing barrel and the guide pipe communicate with each other. Under the action of gravity, the slurry enters the borehole through the guide pipe. The stirring of the blasting agent and water is completed through the above steps, and then the stirred slurry is injected into the borehole. During this process, the safety cover isolates the personnel from the stirring device, thereby achieving the effect of improving the safety of the process of mixing water and blasting agent into slurry and then pouring it into the borehole.

[0009] Furthermore, one end of the material guide tube away from the mixing barrel is fixedly connected to a guide plate, and one side of the guide plate away from the material guide tube abuts against the inner wall of the drilled hole.

[0010] By adopting the above solution, the guide plate is tilted, and the guide plate is tilted from the guide tube toward the inner wall of the borehole, so that the guide plate facilitates the slurry in the guide tube to be introduced into the borehole.

[0011] Furthermore, a first container and a second container are placed in the safety cover, the first container is arranged on a side close to the first feed port, and the second container is arranged on a side close to the second feed port, both of the first container and the second container are in contact with the working surface, the first container is used to hold water, and the second container is used to hold blasting agent; a first feed pipe is arranged between the first container and the first feed port, and a second feed pipe is arranged between the second container and the second feed port, both ends of the first feed pipe are fixedly connected to the first container and the first feed port, respectively, and both ends of the second feed pipe are fixedly connected to the second container and the second feed pipe, respectively.

[0012] By adopting the above scheme, blasting agents are used to blast rocks. The blasting agents need to be mixed with water to form a slurry, and then the slurry is injected into the borehole. The slurry has a certain ratio requirement between the blasting agent and water. The blasting agent is placed in the second container, and a certain proportion of water is placed in the first container according to the dosage of the blasting agent. The water is then injected into the mixing barrel through the first feed pipe, and the blasting agent is injected into the mixing barrel through the second feed pipe. The water and the blasting agent are then stirred to form a slurry that meets the requirements.

[0013] Furthermore, a first observation slot is provided on the first container, and a second observation slot is provided on the second container. Transparent plates are fixedly connected to the first observation slot and the second observation slot, and the state of the materials in the first container and the second container can be observed through the first observation slot and the second observation slot.

[0014] By adopting the above scheme, since the water in the first container and the blasting agent in the second container are of certain dosages, a first observation groove is opened on the first container, a second observation groove is opened on the second container, and a transparent plate is fixedly connected to the first observation groove and the second observation groove, and then the state of the material in the first container and the second container can be observed through the transparent plate. When the material in the first container and the second container has been injected into the mixing barrel, it proves that the dosage ratio of the water and the blasting agent in the mixing barrel is correct, and then stirring can be performed.

[0015] Furthermore, the sealing device includes a sealing plate and a pulling member, a through groove is opened on the frame, the sealing plate is arranged in the through groove, the sealing plate is slidably connected to the through groove, and the pulling member is fixedly connected to the side wall of the sealing plate.

[0016] By adopting the above scheme, a through groove is opened on the frame, and then a sealing plate is slidably connected in the through groove, so that the opening and closing state between the mixing barrel and the material guide tube can be controlled. Because a pulling member is fixedly connected to the side wall of the sealing plate, the sliding state of the sealing plate in the through groove can be controlled by pulling the pulling member, thereby controlling the opening and closing state of the sealing plate between the mixing barrel and the material guide tube.

[0017] Furthermore, a pulling opening is provided on the side wall of the safety cover, and one end of the pulling member away from the sealing plate passes through the pulling opening. A person pulls the pulling member outside the safety cover to control the opening and closing of the sealing device between the mixing barrel and the material guide pipe.

[0018] By adopting the above scheme, a pulling opening is opened on the side wall of the safety cover, and then one end of the pulling piece is passed through the pulling opening, so that personnel can pull the pulling piece outside the safety cover, thereby controlling the sliding state of the sealing plate in the through groove, and then controlling the opening and closing state of the seal between the mixing barrel and the material guide pipe, thereby achieving the purpose of protecting personnel.

[0019] Furthermore, one end of the pulling member away from the sealing plate is fixedly connected with a pulling ring.

[0020] By adopting the above solution, a pulling ring is fixedly connected to the end of the pulling member away from the sealing plate, so that people can pull the pulling rod easily.

[0021] Furthermore, a stabilizing structure is arranged between the frame and the working surface, and the stabilizing structure includes a first stabilizing member and a second stabilizing member, the first stabilizing member and the second stabilizing member are respectively located on both sides of the mixing barrel, the first stabilizing member and the second stabilizing member both pass through the frame and abut against the working surface, and the first stabilizing member and the second stabilizing member are both threadedly connected to the frame.

[0022] By adopting the above scheme, a stabilizing structure is set between the frame and the working surface, so that the connection between the frame and the working surface is more stable. When the relative position relationship between the frame and the working surface is determined, the first stabilizing member and the second stabilizing member are rotated in sequence, and the first stabilizing member and the second stabilizing member are both moved in the direction close to the working surface until the first stabilizing member and the second stabilizing member are in contact with the working surface.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up the safety device, a safety cover is first set up, and the safety cover isolates the area where water and blasting agent are mixed from personnel. Because a sealing device is set up, when water is injected into the mixing barrel through the first feed port and blasting agent is injected into the mixing barrel through the second feed port, the sealing device is used to seal the mixing barrel and the guide pipe until a certain proportion of water and blasting agent are injected into the mixing barrel, and the water and the blasting agent are stirred to form slurry, and then the sealing device is opened to make the mixing barrel and the guide pipe communicate with each other. Under the action of gravity, the slurry enters the borehole through the guide pipe. The stirring of the blasting agent and water is completed through the above steps, and then the stirred slurry is injected into the borehole. During this process, the safety cover isolates the personnel from the stirring device, thereby achieving the effect of improving the safety of the process of mixing water and blasting agent into slurry and then pouring it into the borehole;

[0025] 2. By setting up a first container and a second container, a blasting agent is used to blast the rock. The blasting agent needs to be mixed with water to form a slurry, and then the slurry is injected into the borehole. The slurry has a certain ratio requirement between the blasting agent and water. The blasting agent is placed in the second container, and a certain proportion of water is placed in the first container according to the dosage of the blasting agent. Then, the water is injected into the mixing barrel through the first feeding pipe, and the blasting agent is injected into the mixing barrel through the second feeding pipe. Then, the water and the blasting agent are stirred to form a slurry that meets the requirements;

[0026] 3. By setting up a sealing device, by opening a through groove on the frame, and then slidingly connecting a sealing plate in the through groove, the opening and closing state between the mixing barrel and the material guide tube can be controlled. Because a pulling member is fixedly connected to the side wall of the sealing plate, by pulling the pulling member, the sliding state of the sealing plate in the through groove can be controlled, thereby controlling the opening and closing state of the sealing plate between the mixing barrel and the material guide tube.
