Technical Field

[0001] The utility model relates to the technical field of blasting drilling auxiliary supports, in particular to an open-pit mine slope pre-splitting blasting drilling auxiliary support. Background Art

[0002] A blasting drilling auxiliary support is a tool used to assist drilling equipment in performing precise drilling during blasting operations. The blasting drilling auxiliary support is composed of a base, a column, a beam, a clamp, and a fixing device. The base is made of thick steel or other solid materials to ensure that the entire support can stably support the drilling equipment during the drilling process. The shape and size of the base will be designed according to different usage scenarios and the size of the drilling equipment. It is generally rectangular or square with a large contact area to disperse pressure. The column is the main structure supporting the drilling equipment. It is generally made of high-strength steel pipe or aluminum alloy material. It needs to have sufficient strength and rigidity to withstand various forces during the drilling process, including the weight of the drilling equipment, the thrust and reaction force of the drill rod, etc.

[0003] In the current existing technology, when the blasting drilling auxiliary support is erected on the slope of an open-pit mine, the base of the auxiliary support needs to be placed stably on the mine slope. Since the mine slope has a certain inclination angle, a heavy object needs to be placed on one side of the base to prevent the auxiliary support from sliding, which makes the erection of the auxiliary support on the mine slope more troublesome and causes greater labor intensity for the workers. Therefore, an open-pit mine slope pre-splitting blasting drilling auxiliary support is proposed to solve the above problems. Utility Model Content

It solves the problem that when the auxiliary bracket for blasting drilling is erected on the slope of an open-pit mine, the base of the auxiliary bracket needs to be placed stably on the slope of the mine. Since the slope of the mine has a certain inclination angle, a heavy object needs to be placed on one side of the base to prevent the auxiliary bracket from sliding, which makes the erection of the auxiliary bracket on the slope of the mine more troublesome and leads to higher labor intensity for the staff.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Please refer to Figures 1 to 3 In the embodiment, the open-pit mine slope pre-splitting blasting drilling auxiliary support comprises a support base 1, a metal stand 2 is arranged on the top of the support base 1, a support beam 3 is arranged on the metal stand 2, a support structure and an auxiliary structure are arranged in the support base 1, the metal stand 2 is fixedly installed on the top of the support base 1, the support beam 3 is fixedly installed on the metal stand 2, a clamp is fixedly installed on the support beam 3, and the number of the support structure and the auxiliary structure is four.

[0021] In the embodiment of this example, the support structure includes a support frame 41 fixedly installed at the bottom of the bracket base 1, and a support nail column 42 with one end penetrating and extending to the inside of the bracket base 1 is slidably installed inside the support frame 41. A limiting component 43 is provided inside the support frame 41 for limiting the up and down sliding trajectory of the support nail column 42. The limiting component 43 includes a limiting column and a through groove. The through groove is opened on the front side of the support nail column 42. The limiting column is fixedly installed on the front side wall of the inner cavity of the support frame 41. The outer surface of the limiting column is slidably connected to the inner wall of the through groove, so that the supporting nail column 42 can only be limited to the limit column. The outer surface moves up and down, and a mounting frame 44 is installed on the bracket base 1, which is sleeved on the outside of the supporting nail column 42. A threaded sleeve 45 with one end passing through and extending to the outside is rotatably installed inside the mounting frame 44. The threaded sleeve 45 is threadedly connected to the outer surface of the supporting nail column 42. An annular handwheel 46 is fixedly installed on the outer surface of the threaded sleeve 45. The annular handwheel 46 includes a connecting ring and a connecting rod. One end of the connecting rod is fixedly connected to the connecting ring, and the other end of the connecting rod is fixedly connected to the outer surface of the threaded sleeve 45, which is convenient for the staff to rotate the connecting ring and drive the threaded sleeve 45 to rotate.

[0022] The mounting frame 44 includes a cylindrical frame and a bearing. The bearing is fixedly mounted on the inner circumferential wall of the cylindrical frame. The inner circumferential wall of the bearing is fixedly connected to the outer surface of the threaded sleeve 45 to facilitate the use of the bearing to support the rotation of the threaded sleeve 45.

[0023] By adopting the above technical solution, the annular handwheel 46 is rotated to drive the threaded sleeve 45 inside the mounting frame 44 to rotate, so that the support nail column 42 threadedly connected inside the threaded sleeve 45 moves downward on the outer surface of the limiting column, and then the moving support nail column 42 is inserted into the mine slope, and then the other support nail column 42 on the same side is inserted into the mine slope in the same way, so that the two support nail columns 42 on the same side support one side of the bracket base 1.

[0024] In this embodiment, the auxiliary structure includes a mounting component 47 connecting the mounting frame 44 and the bracket base 1. The mounting component 47 includes four connecting plates and four fixing screws. The four connecting plates are respectively fixedly connected to the outer surface of the mounting frame 44. One end of the four fixing screws passes through the connecting plates and extends to the interior of the bracket base 1. The fixing screws are threadedly connected to the bracket base 1 to facilitate fixing the mounting frame 44 on the bracket base 1. An annular sealing plate 48 located inside the support frame 41 is fixedly installed on the top of the bracket base 1, and an annular limiting plate 49 located at the top of the support frame 41 is fixedly installed on the outer surface of the threaded sleeve 45.

[0025] The annular limiting plate 49 and the annular sealing plate 48 provide support and limitation, thereby preventing the threaded sleeve 45 and the bearing from slipping and stabilizing the rotation of the threaded sleeve 45 .

[0026] By adopting the above technical solution, the annular sealing plate 48 and the cylindrical frame are used to support the bearing, and the annular limit plate 49 is used to limit the rotation position of the threaded sleeve 45 to prevent the threaded sleeve 45 from being disconnected due to excessive force.

[0027] The working principle of the above embodiment is:

[0028] When using the open-pit mine slope pre-splitting blasting drilling auxiliary bracket, according to the position of the bracket base 1, the annular handwheel 46 is rotated to drive the threaded sleeve 45 inside the mounting frame 44 to rotate, so that the support nail column 42 threadedly connected inside the threaded sleeve 45 moves downward on the outer surface of the limit column, thereby allowing the moving support nail column 42 to be inserted into the mine slope, and then continue to insert the other support nail column 42 on the same side into the mine slope in the same way, so that the two support nail columns 42 on the same side support one side of the bracket base 1, thereby preventing the bracket base 1 from sliding on the mine slope.
