Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of underground equipment and relates to a retractable blasting cable drum rack used for underground blasting operations. Background Art
[0002] Blasting operations in metal mines are one of the most critical processes in the mining and production of metal and non-metallic ores. They primarily involve hole layout, drilling, charging, plugging, wiring, safety inspections, detonation, and slag removal. Detonating cords are primarily used to control the blasting process and ensure safe and effective blasting. Currently, detonating cords are disposable and are used in large quantities during blasting operations. Therefore, how to quickly store detonating cords, including reels of varying diameters, is a challenge for existing technicians. Utility Model Content
[0003] The purpose of the utility model is to address the problems existing in the prior art and provide a retractable blasting cable drum rack for underground blasting operations, which solves the problem of how to quickly store blasting wires and how to quickly store blasting cable drums with different diameters.
[0004] To this end, the present invention adopts the following technical solutions:
[0005] The top of the lifting link is connected with the lifting link of the lifting link, and the bottom of the lifting link is connected with the lifting link of the lifting link.
[0006] Furthermore, a rotating handle is provided at the edge of the turntable.
[0007] Furthermore, the inner wall of the first insertion hole is provided with a thread, and the outer wall of the rotating shaft is provided with a thread, and the two are connected by the thread.
[0008] The beneficial effects of the present invention are:
[0009] The utility model can facilitate the laying of detonating cables and the positioning of detonating cable reels, and is suitable for storing detonating cable reels with different reel diameters. When the detonating wire needs to be laid, the positioning pin is stored in the limit cover to realize fast wire release. When the detonating wire needs to be reeled up, the positioning pin is inserted in a suitable position according to the reel diameter of different detonating wires. After the cable reel is relatively fixed, the handle is quickly rotated to achieve the effect of immediate storage. At the same time, the utility model is easy to manufacture, convenient for construction workers to construct, economical and applicable, and suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a schematic diagram of the main structure of the utility model;
[0011] Figure 2 It is a rear view structural schematic diagram of the present utility model.
[0012] In the figure, 1-base, 2-support rod, 3-turntable, 3a-rotating shaft, 4-pull rod, 5-limiting cover, 6-first socket, 7-connecting rod, 8-second socket, 9-locating pin, 10-rope body, 11-rotating handle. DETAILED DESCRIPTION
[0013] The technical solution of the present invention is described below in conjunction with the accompanying drawings and implementation methods.
[0014] like Figure 1 and 2 As shown, a retractable blasting cable drum rack for underground blasting operations includes a base 1, which is a square frame with a vertically arranged support rod 2 on the top. Two symmetrically arranged turntables 3 are provided on the sides of the support rod 2, and the two are rotatably connected by a rotating shaft 3a; a pull rod 4 is provided between the base 1 and the support rod 2, one end of the pull rod 4 is connected to the base 1, and the other end is connected to the support rod 2.
[0015] One end of the rotating shaft 3a is movably connected to the support rod 2, and the other end is provided with a limit cover 5. The limit cover 5 is circular and has a first socket 6 in the middle. Specifically, the inner wall of the first socket 6 is provided with a thread, and the outer wall of the rotating shaft 3a is provided with a thread, and the two are connected by threads.
[0016] The turntable 3 on the side close to the limit cover 5 is provided with four connecting rods 7 arranged in a cross shape, and the connecting rod 7 is provided with a number of second sockets 8 arranged in a regular pattern. The limit cover 5 is provided with a number of positioning pins 9 around the circumference of the first socket 6, and the limit cover 5 is provided with a third socket (not shown in the figure) at the position corresponding to the positioning pin 9. The third socket is used to receive the positioning pin 9, and the positioning pin 9 is inserted into any one of the second sockets 8 to play a limiting role. The end of the positioning pin 9 is provided with a rope body 10, and the other end of the rope body 10 is fixedly connected to the limit cover 5; specifically, the length of the positioning pin 9 is slightly longer than the thickness of the connecting rod 7, that is, when the positioning pin 9 is inserted into the second socket 8, it is fixedly connected to the connecting rod 7 by bolts, and both ends of the positioning pin 9 are exposed from the second socket 8 by 1cm~2cm, which will not affect the rotation of the turntable 3 and the storage of the detonating line.
[0017] In addition, a rotating handle 11 is provided at the edge of the turntable 3 .
[0018] The utility model is used in the following process:
[0019] When it is necessary to lay the detonating wire, the limit cover 5 and one of the turntables 3 are removed from the rotating shaft 3a and then the detonating cable drum is installed. Since there is no need to fix the cable drum when laying the cable, the positioning pin 9 is in the initial state, that is, it is inserted into the third socket on the limit cover 5. At this time, there is no limit on the detonating cable drum, and the wire pulling and laying work can be carried out smoothly.
[0020] When the blasting operation is completed and the detonating wire needs to be reeled in, first, the empty cable drum is placed between the two turntables 3, and the positioning pins 9 are inserted into the second insertion holes 8 at appropriate positions according to the diameters of the different detonating wires. The four positioning pins 9 will relatively fix the side of the empty cable drum close to the positioning pins 9. At this time, the detonating cable drum and the rotating shaft 3a no longer produce relative movement. The friction between the two is increased by the rope body 10 to produce a limiting effect. The two will rotate at the same time, and the staff starts to quickly turn the handle 11 to drive the turntable 3 to rotate and reel in the cable until the detonating wire is stored.
