Description

Technical Field

[0001] The utility model relates to the technical field of blasting and drilling, in particular to a blasting and drilling device for building demolition. Background Technique

[0002] As a scientific and technological method, blasting is widely used. However, its application in engineering is undoubtedly the most important and common. In mining and mountain opening, drill and blast methods are used to excavate tunnels for railway and highway construction. It is also used in some water conservancy projects and now in urban areas for building demolition. In the comparative case with the publication number CN109099805A, the present invention discloses a blasting and drilling device for building demolition, which includes a handle, an external auger, a drilling outer cylinder, and a drilling end. The handle is provided with two groups in a concave shape. In the device, drilling is carried out through the drilling outer cylinder. The drilling outer cylinder is a cylindrical structure, and an external auger is sleeved outside the drilling outer cylinder. The drilling outer cylinder drills holes through the external auger, and the drilling outer cylinder ensures that the hole diameters are basically the same and the drilling is relatively flat. When drilling, the soil and debris at the outer circle of the hole are lifted and removed through the auger structure, and the soil at the inner circle of the hole enters the inside of the drilling outer cylinder through the corresponding external through holes and internal through holes, achieving the purpose of loading the soil and debris into the drilling outer cylinder. When disassembling the screw, the upper connecting sleeve and the lower connecting sleeve can be separated, which is convenient for pouring out the soil and debris in the drilling outer cylinder. The cleaning inside the hole is convenient and simple, which is convenient for placing explosives and is suitable for popularization.

[0003] However, in the implementation of the related technology, it is found that the above-mentioned blasting and drilling device for building demolition has the following problems. The comparative case realizes the functions of disassembly, installation, and cleaning through the cooperation of structures such as the handle, the external auger, the drilling outer cylinder, and the drilling end. The structure is single and the operation is cumbersome. For the existing blasting and drilling equipment, it is rather cumbersome to replace the drill bit when dealing with different-structured building bodies, which reduces the convenience of using the blasting and drilling equipment.

[0004] Therefore, it is necessary to design and transform the blasting and drilling to effectively prevent the problem that it is rather cumbersome to replace the drill bit of the blasting and drilling equipment when dealing with different-structured building bodies. Content of the Utility Model

[0005] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide a blasting and drilling device for building demolition, which has the advantage of convenient disassembly and installation, and solves the problem that it is rather cumbersome to replace the drill bit of the blasting and drilling equipment when dealing with different-structured building bodies.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A blasting and drilling device for building demolition, including;

[0023] As Figures 1 to 4 shown, a building demolition and blasting hole drilling device provided by the present utility model includes;

[0024] Gun body 1;

[0025] The output end of the gun body 1 is fixedly connected with a drill bit 2, and the surface of the drill bit 2 is movably sleeved with a fixed ring 3. The front end and the back end of the bottom of the inner wall of the fixed ring 3 are both slidably connected with a fixing mechanism 4;

[0026] The fixing mechanism 4 includes a sliding column 41, an arc ring 42, a horn ring 43, a positioning pin 44 and a hollow drill bit 45. The front end and the back end of the bottom of the inner wall of the fixed ring 3 are both slidably connected with a sliding column 41. The top of the sliding column 41 is fixedly connected with an arc ring 42. The bottom of the drill bit 2 and inside the arc ring 42 are fixedly connected with a horn ring 43. The surface of the horn ring 43 is in contact with the inner side of the arc ring 42. The left side of the arc ring 42 is fixedly connected with a positioning pin 44. The left side of the positioning pin 44 penetrates through the fixed ring 3 and is inserted with a hollow drill bit 45.

[0027] Refer to Figure 3 , a return spring 5 is sleeved on the surface of the positioning pin 44. The left side and the right side of the return spring 5 are respectively fixedly connected with the left side of the inner wall of the fixed ring 3 and the left side of the arc ring 42.

[0028] As a technical optimization scheme of the present utility model, through the setting of the return spring 5, it can assist the positioning pin 44 to work, and at the same time play a role of reset buffering, avoiding the positioning pin 44 being unable to reset after moving and causing the machine to stop working continuously.

[0029] Refer to Figure 4, at the front end and the back end of the bottom inner wall of the fixed ring 3 and at the position of the sliding column 41, a sliding groove 6 is provided, and the sliding groove 6 is used in cooperation with the sliding column 41.

[0030] As a technical optimization scheme of the present utility model, through the setting of the sliding groove 6, it can assist the sliding column 41 to work and play a role in limiting at the same time, avoiding the phenomenon that the sliding column 41 is offset during the moving process.

[0031] Reference Figure 3 , a rubber pad 7 is fixedly connected to the inner side of the arc ring 42, and the rubber pad 7 is used in cooperation with the arc ring 42.

[0032] As a technical optimization scheme of the present utility model, through the setting of the rubber pad 7, it can assist the horn ring 43 to work and avoid the phenomenon that the arc ring 42 directly contacts the horn ring 43 and causes wear.

[0033] Reference Figure 4 , a threaded through hole 8 is provided on the surface of the fixed ring 3 and corresponding to the position of the drill bit 2, and the threaded through hole 8 is used in cooperation with the drill bit 2.

[0034] As a technical optimization scheme of the present utility model, through the setting of the threaded through hole 8, it can assist the drill bit 2 to work and avoid the phenomenon that the fixed ring 3 is separated from the surface of the drill bit 2.

[0035] Reference Figure 3 , the positioning pin 44 is made of aluminum alloy, and the positioning pin 44 is used in cooperation with the arc ring 42.

[0036] As a technical optimization scheme of the present utility model, through the setting of the positioning pin 44, the strength can be increased and the phenomenon that the positioning pin 44 is deformed and damaged during use can be avoided.

[0037] The working principle and usage process of the present utility model: When in use, rotate the hollow drill bit 45 counterclockwise. The rotation of the hollow drill bit 45 drives the positioning pin 44 and the fixed ring 3 to rotate synchronously. The rotation of the fixed ring 3 screws out upward along the surface of the drill bit 2. When the fixed ring 3 screws out, the arc ring 42 does not contact the widest part of the horn ring 43. Then the return spring 5 works to push the positioning pin 44 to contract into the interior of the fixed ring 3. The movement of the positioning pin 44 drives the arc ring 42 and the sliding column 41 to move accordingly. The sliding column 41 moves stably in cooperation with the sliding groove 6. Finally, the contraction of the positioning pin 44 releases the fixation of the hollow drill bit 45, and it can be disassembled and replaced. Similarly, conversely, sleeve the hollow drill bit 45 on the surface of the fixed ring 3 and rotate the fixed ring 3 clockwise until the positioning pin 44 fixes the hollow drill bit 45 to complete the installation.

[0038] In summary, for the building demolition and blasting drilling device, through the combined use of the gun body 1, the drill bit 2, the fixing ring 3, the fixing mechanism 4, the sliding column 41, the arc ring 42, the horn ring 43, the positioning pin 44 and the hollow drill bit 45, the problem that it is relatively cumbersome to replace the drill bit in the existing blasting drilling equipment when dealing with building bodies of different structures is solved.
