[0021] Embodiment 1:

[0022] The present embodiment provides a rod storage mechanism for a mining trolley, which is used for storing drill rods 1. Figure 1 , Figure 2 As shown, it includes a spiral track 2, a manipulator assembly 3 and a drive assembly 4, the manipulator assembly 3 is located at the opening of the spiral track 2; the spiral track 2 is used to store the drill rod 1 and guide the movement of the drill rod 1; the manipulator assembly 3 is used to grab the drill rod 1 and can move closer to or away from the opening of the spiral track 2; the drive assembly 4 is used to drive the drill rod 1 to move along the spiral track 2.

[0023] The design of the spiral track 2 allows the drill rod 1 to move along the spiral track 2 and can only be moved out from the exit of the spiral track 2. The exit is fixed, and the manipulator assembly 3 does not need to change the grasping position, which improves work efficiency; the manipulator assembly 3 is located at the exit of the spiral track 2, and the drill rod 1 can be grasped by the manipulator assembly 3 when it moves to the exit of the spiral track 2. After grasping the drill rod 1, the manipulator assembly 3 can be away from the spiral track 2, which is convenient for unloading the rod. The overall spiral structure reduces the volume while ensuring the storage capacity of the rod.

[0024] In order to ensure the reliability of the spiral track 2, a guide seat 5 is also included, and the spiral track 2 is located on the guide seat 5; the guide seat 5 is divided into an upper base 6 and a lower base 7, the upper base 6 is located at one end of the drill rod 1, and the lower base 7 is located at the other end of the drill rod 1. In this embodiment, the spiral track 2 is a spiral groove. The spiral track 2 is arranged on the guide seat 5, which can make the structural strength of the spiral track 2 higher, prevent the spiral track 2 from deforming, and improve the reliability of the guidance; the spiral track 2 is distributed at both ends of the drill rod 1, and when the drill rod 1 moves, both ends can be guided by the spiral track 2, so that the movement of the drill rod 1 is stable.

[0025] In order to drive the component 4 reliably, Figure 3 As shown, the driving assembly 4 includes a mounting plate 8, an intermittently moving groove wheel 9 and a first driving member 10 for driving the groove wheel 9 to rotate. The mounting plate 8 is provided with a receiving groove 11 for receiving the drill rod 1. The mounting plate 8 is connected to the groove wheel 9 and rotates synchronously. The mounting plate 8 is arranged concentrically with the spiral track 2. In this embodiment, the first driving member 10 is a rotary motor, which is connected and fixed to the upper base 6; twelve receiving grooves 11 are provided. The design of the mounting plate 8 is convenient for placing the drill rod 1. Multiple drill rods 1 can be placed in a single receiving groove 11, but the two ends of the drill rod 1 will be separated by the spiral track 2, which can prevent the adjacent drill rods 1 in the same receiving groove 11 from colliding. At the same time, the mounting plate 8 can drive the drill rod 1 to move outward along the spiral track 2 when rotating; the design of the groove wheel 9 controls the movement of the drill rod 1 in the spiral track 2 through intermittent motion, which can reduce the required gap between the drill rods 1 and increase the storage amount.

[0026] In order to ensure reliable movement of the sheave 9, the sheave 9 is connected to the first driving member 10 through a transmission connection via a rotating member 12; the rotating member 12 is connected to the output end of the first driving member 10, a shifting block 13 is provided on the rotating member 12, and a notch 14 cooperating with the shifting block 13 is provided on the sheave 9; at least two notches 14 are provided, and the notches 14 are evenly distributed around the rotation center of the sheave 9. In this embodiment, twelve notches 14 are provided. The first driving member 10 drives the rotating member 12 to rotate one circle, and the shifting block 13 will enter from one notch 14 to another notch 14, so that the sheave 9 rotates once, and a drill rod 1 is moved to the exit of the spiral track 2. The intermittent movement also makes it convenient to grab the drill rod 1. The overall driving method is reliable, and there is almost no wear during operation, which not only ensures the stability of the position of the drill rod 1, but also reduces the subsequent maintenance work.

The two mounting plates 8 rotate synchronously, so that the two ends of the drill rod 1 can move synchronously, ensuring that the two ends move reliably in the spiral tracks 2 on both sides to prevent jamming.

[0029] In order to reliably grasp the drill rod 1 , the manipulator assembly 3 includes a gripper 16 and a swing arm 17 . The gripper 16 is used to grasp the drill rod 1 , and the swing arm 17 is used to drive the gripper 16 to move toward or away from the opening of the spiral track 2 .

[0031] In this embodiment, the second driving member 19 is a swing cylinder; an upper robotic arm 24 is provided on the upper base 6, and a lower robotic arm 25 is provided on the lower base 7. One end of the upper robotic arm 24 is connected to the upper base 6, and the other end of the upper robotic arm 24 is rotatably connected to the swing rod 18. One end of the lower robotic arm 25 is connected to the lower base 7, and the other end of the lower robotic arm 25 is rotatably connected to the swing rod 18.

[0032] In order to ensure the reliability of the gripper 16, the gripper 16 includes an upper jaw 21, a lower jaw 22 and a third driving member 23.
