Technical Field

[0001] The utility model relates to the technical field of mine blasting, in particular to a rapid charging device for mine engineering blasting. Background Art

[0002] At present, mine blasting: when explosive bags or charges explode in soil and rock media or structures, the soil and rock media or structures are compressed, deformed, destroyed, loosened and thrown, which is suitable for the mining process of mines.

[0003] Among them, open-pit mine blasting: the main form is step blasting, which can be divided into deep hole step blasting and shallow hole step blasting according to the hole diameter and hole depth. After the hole is opened in the mountain, it is necessary to fill the hole groove with explosives.

[0004] The charging device is a commonly used equipment in mine blasting. There are two types: mechanical and manual. The manual method is to manually measure and fill a certain amount of explosives, but such operation is very dangerous. The mechanical method is for the operator to remotely control the charging robot to fill the explosives. However, it is difficult to connect the pipes filled with explosives with the holes in the mountain. Therefore, a new technical solution needs to be designed to solve this problem. The hole-finding mechanism can be used to quickly connect the pipes filled with explosives on the charging robot with the holes in the mountain. Utility Model Content

[0005] The purpose of the utility model is to provide a rapid charging device for mining engineering blasting, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a rapid charging device for mining engineering blasting, comprising a charging robot, a mechanical arm fixedly mounted on one side of the top of the charging robot, a mounting base fixedly mounted on the other end of the mechanical arm, and a hole-finding mechanism mounted on the mounting base;

[0007] The hole-finding mechanism includes support wheels installed at the four corners on the other side of the mounting seat, a piston cylinder fixedly installed in the middle of the mounting seat, a stuffing cylinder movably installed inside the piston cylinder, a spring sleeved on one end of the stuffing cylinder, and a feeding pipe connected to the other end of the stuffing cylinder.

[0008] As an optional solution of the technical solution of the present application, the two sides of the spring are fixedly installed on the side walls of the piston cylinder and the filling cylinder respectively, and the port of the filling cylinder corresponds to the mine charging port.

[0009] As an optional solution of the technical solution of the present application, a camera is fixedly installed on the top of the robotic arm through a mounting bracket. The camera and the mounting seat correspond to each other and can observe the mining environment.

[0010] As an optional solution to the technical solution of the present application, a material box is fixedly installed on one side of the top of the charging robot, and gunpowder powder is filled inside the material box. A powder elevator is installed on the bottom side of the material box, and the discharge end of the powder elevator is connected to the other end of the feeding pipe, so that the gunpowder can be transported to the charging port of the mine.

[0011] As an optional solution of the technical solution of the present application, a bracket is fixedly installed on the side wall of the robotic arm, and a slip ring is fixedly installed on the side wall of the bracket. The slip ring is movably connected to the stuffing cylinder to support the slip ring.

[0012] As an optional solution of the technical solution of the present application, a fixing ring is fixedly installed at one end of the side wall of the stuffing cylinder, and a pressure sensor is fixedly installed on one side of the fixing ring. The pressure sensor corresponds to the slip ring and can detect whether the fixing ring is docked with the slip ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The technical solution of the present application drives the charging robot to drive the robotic arm and the material box to move in the mine, and before the filling tube is docked with the mine charging port, the robotic arm will first push the mounting seat to fit the side wall of the mine, and wait for the four sets of support wheels on the mounting seat to contact the side wall of the mine. The filling tube inside the hole-finding mechanism will be squeezed by the side wall of the mine. When the robotic arm pushes the mounting seat at a small angle, the compressed filling tube will be supported by the spring and quickly squeezed into the inside of the mine charging port to add gunpowder to the inside of the mine charging port. Compared with the operator controlling the robotic arm to accurately insert the filling tube into the mine charging port, the operation is simpler and more convenient.

[0015] 2. The technical solution of the present application is to fix a pressure sensor on one side of the fixed ring, and the pressure sensor and the slip ring correspond to each other. When the operator controls the robotic arm to align the filling tube with the mine charging port, the filling tube in the mounting seat will be squeezed by the side wall of the mine. After the filling tube is aligned with the mine charging port, the filling tube will be squeezed into the mine charging port by the support force of the compression spring. The pressure sensor installed on the fixed ring will be squeezed with the slip ring. The pressure sensor under pressure will transmit a signal to the control processor, which not only allows the operator to confirm that the filling tube is plugged into the mine charging port, but also can control the powder elevator to transport the gunpowder powder.

[0020] See also Figure 1-2 The utility model provides a technical solution: a rapid charging device for mining engineering blasting, comprising a charging robot 1, a mechanical arm 11 is fixedly mounted on one side of the top of the charging robot 1, a mounting base 2 is fixedly mounted on the other end of the mechanical arm 11, and a hole-finding mechanism is mounted on the mounting base 2;

[0021] The hole-finding mechanism includes support wheels 21 installed at the four corners on the other side of the mounting base 2, a piston cylinder 22 fixedly installed in the middle of the mounting base 2, a filling cylinder 23 movably installed inside the piston cylinder 22, a spring 24 sleeved on one end of the filling cylinder 23, and a feeding pipe 25 connected to the other end of the filling cylinder 23. The two sides of the spring 24 are fixedly installed on the side walls of the piston cylinder 22 and the filling cylinder 23 respectively, and the port of the filling cylinder 23 corresponds to the charging port of the mine.

[0022] In this technical solution, the charging robot 1 is driven to drive the robotic arm 11 and the material box 13 to move in the mine, and before the filling tube 23 is docked with the mine charging port, the robotic arm 11 will preferentially push the mounting seat 2 to fit the mine side wall, and wait for the four sets of support wheels 21 on the mounting seat 2 to contact the mine side wall. Then, the filling tube 23 inside the hole-finding mechanism will be squeezed by the mine side wall. When the robotic arm 11 pushes the mounting seat 2 at a small angle, the compressed filling tube 23 will be supported by the spring 24 and the filling tube 23 will be quickly squeezed into the mine charging port to add gunpowder to the inside of the mine charging port. Compared with the operator controlling the robotic arm 11 to accurately insert the filling tube 23 into the mine charging port, the operation is simpler and more convenient.

[0023] In some technical solutions, a bracket 3 is fixedly installed on the side wall of the robotic arm 11, and a slip ring 31 is fixedly installed on the side wall of the bracket 3. The slip ring 31 is movably connected to the stuffing tube 23 and can support the slip ring 31. A fixed ring 32 is fixedly installed on one end of the side wall of the stuffing tube 23, and a pressure sensor 33 is fixedly installed on one side of the fixed ring 32. The pressure sensor 33 corresponds to the slip ring 31 and can detect whether the fixed ring 32 is docked with the slip ring 31.

[0024] In this technical solution, before the operator controls the robotic arm 11 to align the filling tube 23 with the mine charging port, the filling tube 23 in the mounting seat 2 will be squeezed by the side wall of the mine. After the filling tube 23 is aligned with the mine charging port, the filling tube 23 will be supported by the compression spring 24 and squeezed into the interior of the mine charging port. The pressure sensor 33 installed on the fixed ring 32 will be squeezed with the slip ring 31. The pressure sensor 33 under pressure will transmit a signal to the control processor, which not only allows the operator to confirm that the filling tube 23 is inserted into the mine charging port, but also can control the powder elevator to transport the gunpowder powder.

[0025] In some technical solutions, a material box 13 is fixedly installed on one side of the top of the charging robot 1, and gunpowder powder is filled inside the material box 13. A powder elevator is installed on the bottom side of the material box 13, and the discharge end of the powder elevator is connected to the other end of the feeding pipe 25, so that the gunpowder can be transported to the mine charging port.

[0026] In this technical solution, when the powder elevator inside the material box 13 is driven, the gunpowder powder inside the material box 13 can be transported to the filling tube 23 through the feeding pipe 25 and continuously introduced into the mine charging port.

[0027] In some technical solutions, a camera 12 is fixedly installed on the top of the robotic arm 11 through a mounting frame. The camera 12 corresponds to the mounting seat 2 and can observe the mining environment.

[0028] In this technical solution, when the camera 12 installed on the charging robot 1 observes the mine charging port, the operator can remotely control the mechanical arm 11 on the charging robot 1 to dock the filling tube 23 on the mechanical arm 11 with the mine charging port, and introduce a certain amount of explosive powder into the mine charging port.

[0029] When a rapid charging device for mining engineering blasting is used, it should be noted that the utility model is a rapid charging device for mining engineering blasting, and each component is a universal standard part or a component known to those skilled in the art, and its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0030] During use, the charging robot 1 is first driven to drive the mechanical arm 11 and the material box 13 to move in the mine. When the camera 12 installed on the charging robot 1 observes the charging port of the mine, the operator can remotely control the mechanical arm 11 on the charging robot 1 to make the filling tube 23 on the mechanical arm 11 dock with the charging port of the mine, and introduce a certain amount of explosive powder into the charging port of the mine, which not only improves the charging efficiency, but also avoids manual charging and greatly improves the safety of mine blasting. At the same time, before the filling tube 23 docks with the charging port of the mine, the mechanical arm 11 will first push the mounting seat 2 to fit with the side wall of the mine, and wait for the four sets of support wheels 21 on the mounting seat 2 to contact the side wall of the mine. The filling tube 23 inside the hole-finding mechanism will be squeezed by the side wall of the mine. When the mechanical arm 11 pushes the mounting seat 2 at a small angle, the compressed filling tube 23 will be supported by the spring 24, and the filling tube 23 will be quickly squeezed into the charging port of the mine. The part is used to add gunpowder to the inside of the mine charging port. Compared with the operator manipulating the mechanical arm 11 to accurately insert the filling tube 23 into the mine charging port, the operation is simpler and more convenient. At the same time, a pressure sensor 33 is fixedly installed on one side of the fixing ring 32, and the pressure sensor 33 corresponds to the slip ring 31. When the operator manipulates the mechanical arm 11 to align the filling tube 23 with the mine charging port, the filling tube 23 in the mounting seat 2 will be squeezed by the side wall of the mine. After the filling tube 23 is aligned with the mine charging port, the filling tube 23 will be supported by the compression spring 24 and squeezed into the inside of the mine charging port. The pressure sensor 33 installed on the fixing ring 32 will be squeezed with the slip ring 31. The pressure sensor 33 under pressure will transmit a signal to the control processor, which not only allows the operator to confirm that the filling tube 23 is inserted into the inside of the mine charging port, but also can control the powder elevator to transport the gunpowder powder.
