AI Technical Summary
Detonating cord is difficult to retract and extend during pre-splitting blasting construction, and is prone to forming bends, resulting in low construction efficiency and safety hazards during the pulling process.
A detonating cord auxiliary turntable tool was designed, including a tripod, a disc and a round tube. The disc was connected by a bearing. The surface of the round tube and the disc was pasted with anti-static rubber. The material was 304 stainless steel, which was used to support and facilitate the retraction and release of the detonating cord.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of pre-splitting blasting, in particular to a detonating cord auxiliary turntable tool. Background Art
[0002] The open-pit blasting at the Baiyin Suolkuduke Copper Mine in Fuyun County, Altay Prefecture, Xinjiang involves slope control blasting, using pre-splitting blasting to form a boundary slope or permanent slope, with a maximum step height of up to 24m.
[0003] During pre-splitting blasting, the pre-split holes must be charged and blasted. Uncoupled, spaced charges are used, requiring emulsion explosives to be spaced throughout the hole and detonated with a detonating cord. However, detonating cords are packaged in rolls, and without any assistance during use, pulling on just one end can easily cause a bend. They must be properly organized before further use, and regulations prohibit violent pulling of detonating cords. Therefore, dedicated personnel are required to retract and release the cords during construction, wasting labor and reducing overall construction efficiency.
[0004] In this regard, in response to this technical problem, the present application proposes a detonating cord auxiliary turntable tool. Utility Model Content
[0005] The purpose of the present utility model is to solve the shortcomings of the prior art and to propose a detonating cord auxiliary turntable tool, which aims to make the retraction and extension of the detonating cord more convenient, thereby improving the overall construction efficiency, and making it difficult for the detonating cord to form bends when being pulled, and to improve the safety of the device when being pulled by sticking anti-static rubber on the part that contacts the detonating cord.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A detonating cord auxiliary turntable tool includes a tripod for supporting a device body, the tripod consisting of three legs, the top side of the tripod being rotatably connected to a disc for placing a detonating cord via a bearing, the top middle end of the disc being fixedly connected to a circular tube for sleeved with the detonating cord, and the surfaces of the circular tube and the disc being both adhered with anti-static rubber.
[0008] Furthermore, the circular tube, the circular disc and the tripod are all made of 304 stainless steel.
[0009] Furthermore, the length of the circular tube is 340 mm.
[0010] Furthermore, the diameter of the disc is 250 mm.
[0011] Furthermore, the length of the support leg is 277 mm.
[0012] The utility model has the following beneficial effects:
[0013] In the utility model, the detonating cord is mounted on the device through a circular tube, and the disc is rotated by a bearing when the detonating cord is pulled, thereby making the resistance encountered by the detonating cord very small during pulling, and making it difficult for the detonating cord to bend during pulling. In addition, by sticking anti-static rubber on the circular tube and the disc, the safety and convenience of pulling the detonating cord are improved, thereby improving the overall construction efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Reference Figure 1-Figure 3The utility model provides an embodiment of a detonating cord auxiliary turntable tool, comprising a tripod 1 for supporting the main body of the device, the tripod 1 is composed of three legs, and the tripod 1 composed of three legs provides temperature support for the device, and the angle between the three legs is 120 degrees. The top side of the tripod 1 is rotatably connected to a disc 2 for placing the detonating cord through a bearing 4, and the rotatable disc 2 allows the detonating cord to be pulled when it is pulled, and a round tube 3 for sheathing the detonating cord is fixedly connected to the middle end of the top side of the disc 2, and the round tube 3 is used to place the detonating cord. The ring-shaped detonating cord is sheathed on the circular tube 3. The surfaces of the circular tube 3 and the disc 2 are both pasted with anti-static rubber. By pasting the anti-static rubber on the circular tube 3 and the disc 2, the safety of the part where the device contacts the detonating cord is improved. The circular tube 3, the disc 2 and the tripod 1 are all made of 304 stainless steel. The circular tube 3, the disc 2 and the tripod 1 made of 304 stainless steel improve the sturdiness of the device and increase the service life of the device. The length of the circular tube 3 is 340 mm, the diameter of the disc 2 is 250 mm, and the length of the legs is 277 mm.
[0021] Working principle: First, put the ring-shaped detonating cord into the outer wall of the circular tube 3, and then directly pull one end of the detonating cord. The disc 2 will rotate as the detonating cord is pulled. The pulling resistance is small and no bends will be formed during the pulling. Since the disc 2 and the circular tube 3 are pasted with anti-static rubber, the safety is better when pulling the detonating cord, and it is very convenient to retract and release the detonating cord.
[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
