[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention:

[0021] like Figure 1-7As shown, a safety rope fixing device for edge charging of an open-pit blasting platform comprises a blocking rod A1, a blocking rod B2 and a main rod 3, wherein the main rod 3 is cylindrical; the interior of the main rod 3 is hollow, and an internal thread is provided on the inner side of the lower end opening to facilitate connection to the connecting portion of the lower end; a blocking rod A1 is welded laterally on the upper end of the outer side of the main rod 3 to facilitate assembly by operators, and convenient for operators to take and prevent the fixing rope from falling off from the fixing groove 4; a blocking rod B2 is welded below the outer side of the main rod 3 parallel to the blocking rod A1 to fix the device as a whole at the port of the blast hole; a fixing groove 4 is provided in the middle position of the main rod 3 to facilitate connection of the fixing rope and prevent sliding; the fixing groove 4 is located between the blocking rod A1 and the blocking rod B2; the lower end of the main rod 3 is connected to a connecting portion through an internal thread, and is inserted into the blast hole to better bear the weight of the operator, and secondly, it is convenient for reuse, and the blast hole can be replaced at any time according to the need of filling explosives.

[0022] Specifically, the connecting part is composed of a connecting rod a5, a connecting rod b6 and a connecting rod c7; the connecting rod a5, the connecting rod b6 and the connecting rod c7 are all hollow; the upper ends of the connecting rod a5, the connecting rod b6 and the connecting rod c7 are each provided with two symmetrical through holes 8; the outer sides of the upper and lower ends of the connecting rod a5 are respectively provided with external threads; the inner side of the upper end of the connecting rod b6 is provided with an internal thread, and the lower end is provided with an external thread; the inner side of the upper end of the connecting rod c7 is provided with an internal thread; the upper end of the connecting rod a5 is threadedly connected to the main rod 3; the lower end of the connecting rod a5 is threadedly connected to the upper end of the connecting rod b6; the lower end of the connecting rod b6 is threadedly connected to the upper end of the connecting rod c7.

[0023] Specifically, the two through holes 8 on the connecting rod a5, the connecting rod b6 and the connecting rod c7 can be used in conjunction with the lifting rod 9 respectively, which can facilitate the operator to first fix each connecting rod in the blast hole, then thread the other connecting rod and pull it out, and then lower the connected connecting rod into the blast hole, mainly to facilitate the operator to assemble the connecting part.

[0024] Specifically, the connecting rod a5, the connecting rod b6 and the connecting rod c7 are all made of hollow steel pipes.

[0025] Specifically, the length of the connecting rod a5, the connecting rod b6 and the connecting rod c7 after being connected is not less than 1000 mm; the diameter of the blocking rod A1 and the blocking rod B2 is not less than 30 mm, and the length is not less than 300 mm.

[0026] When in use, first insert the lifting rod 9 into the through hole 8 of the connecting rod c7, and the operator lifts it into a blast hole 14 on the blasting platform 12 and places it. Then, after the connecting rod b6 is threadedly connected from the upper end of the connecting rod c7, the operator first holds it steady, and then pulls out the lifting rod 9 and inserts it into the through hole 8 of the connecting rod b6 to place the connected connecting rod b6 and connecting rod c7 downward, and then connects the rod a5 and the main rod 3 in turn in the same way. After the connection, the blocking rod B2 of the main rod 3 fixes the entire device in a blast hole 14, and then fixes one end of the safety rope 11 in the fixing groove 4, and the other end is fixed to the operator 10. The operator 10 enters from another blast hole 14 close to the slope 13 to carry out the explosive loading work. When moving, the operator only needs to pull out the entire device and insert it into the corresponding blast hole. It can be used repeatedly, which is flexible and convenient.

[0027] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be covered by the protection scope of the utility model.
