Description
TECHNICAL FIELD
[0001] The utility model belongs to mine equipment technical field relates to a mine electronic detonator rack for underground blasting. BACKGROUND
[0002] In the existing mine underground daily blasting operation, electronic detonators often fall into the mud and are lost or damaged, or electronic detonators of different segments are mixed together, which has certain safety hazards and increases mining costs. UTILITY MODEL CONTENTS
[0003] The utility model discloses a mine electronic detonator rack for underground blasting, which solves the problem of loss of electronic detonators due to lack of special storage tools, mixing of electronic detonators of different segments, and certain safety hazards and increased mining costs.
[0004] Therefore, the utility model adopts the following technical scheme:
[0005] A mine electronic detonator rack for underground blasting includes a vertically arranged rack shaft, a handle at the top of the rack shaft, and a plurality of symmetrically arranged rack legs at the bottom of the rack shaft.
[0006] The rack legs are Z-shaped, including two first and second rod bodies arranged in parallel, and the two are connected by a third rod body.
[0007] The first rod body is fixedly connected to the outer wall near the bottom of the rack shaft, and the second rod body is perpendicularly connected to the ground.
[0008] The outer wall near the top of the rack shaft is provided with a plurality of symmetrically arranged rest rings, which are circular in shape.
[0009] The bottom of the rest ring is provided with a detonator barrel, and the detonator barrel is arranged in the rest ring.
[0010] Further, the included angle between the first, second and third rod bodies is 120-150 degrees.
[0011] Further, the vertical section of the handle is an isosceles triangle.
[0012] This invention allows electronic detonators used in underground operations to be stored in sections, making them convenient for operators to access and preventing accidents such as loss, damage, or confusion of sections. In addition, this invention is simple to manufacture, easy to move, and occupies little space, making it particularly suitable for the temporary storage of electronic detonators during underground mining. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the structure of this utility model.
[0014] In the diagram, 1-frame shaft, 2-support ring, 3-frame leg, 3a-first rod, 3b-second rod, 3c-third rod, 4-handle, 5-detonator barrel. Detailed Implementation
[0015] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.
[0016] like Figure 1 As shown, a placement frame for electronic detonators used in underground blasting in mines includes a vertically arranged frame shaft 1, which is made of DN20 steel pipe. The frame shaft 1 has a handle 4 at the top and several symmetrically arranged frame legs 3 at the bottom. The vertical cross-section of the handle 4 is an isosceles triangle. The frame legs 3 are Z-shaped and include two parallel first rods 3a and second rods 3b, which are connected by a third rod 3c. The angle between the first rod 3a, the second rod 3b and the third rod 3c is 120 degrees to 150 degrees. The first rod 3a is fixedly connected to the outer wall of the frame shaft 1 near the bottom, and the second rod 3b is in contact with the ground and is perpendicular to the ground.
[0017] The outer wall near the top of the frame shaft 1 is provided with three symmetrically arranged support rings 2. The support rings 2 are circular, and the bottom of them is provided with a detonator barrel 5. The detonator barrel 5 is engaged with the support rings 2.
[0018] The usage process of this utility model is as follows:
[0019] Firstly, the size of the detonator barrel 5 is processed, the outer diameter of the detonator barrel 5 is about 5 cm away from the barrel mouth, which is the same size as the inner diameter of the resting ring 2, and the outer diameter of the remaining section is slightly larger than the resting ring 2, so that the detonator barrel 5 is stably placed in the resting ring 2 without falling; then use DN20 steel pipe to make frame shaft 1, length 40 cm; use Φ16 mm round steel to make three same frame legs 3, length 40 cm, both ends are bent 10 cm, with the middle section at 120° angle, and the three sections after bending are in the same plane, select one end of the three frame legs 3 parallel to the frame shaft 1 and weld it on the outer surface of the lower pipe of the frame shaft 1, the angle between the three frame legs 3 is 120° and the frame leg 3 is in the same plane; then use Φ10 mm steel bar to make three same resting rings 2, bend the steel bar into a ring with a diameter of 15 cm, reserve a welding head with a length of 3 cm at the joint, and evenly distribute the reserved welding parts of the three resting rings 2 at the top of the frame shaft 1 10 cm long and weld them; finally, weld the handle 4 at the top of the frame shaft 1, select three steel pipes with a length of 10 cm, weld them into an isosceles triangle, weld the top angle of the isosceles triangle at the top of the frame shaft 1, and the bottom edge is perpendicular to the frame shaft 1. After the above steps are completed, the detonator barrel 5 is placed in the resting ring 2 with the mouth upward, and the detonator barrel 5 is just clamped in the resting ring 2 5 cm away from the barrel mouth; before use, polish each welding part and cut edge part, and brush anti-rust paint; when using, place the device on a flat ground, make the whole placing frame perpendicular to the ground.
