Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a rod unloading device. Background Technology

[0002] A raise boring machine is a type of shaft drilling equipment that uses rotary drilling to break rocks and create holes, and can also reverse the hole to enlarge it. It is mainly used in underground mines and other engineering projects to construct ventilation shafts, filling shafts, or pipeline shafts by drilling pilot holes in the forward direction and then enlarging them in the reverse direction. The raise boring machine transmits the torque of the main power head to the drilling tool system via hydraulic power. The cutterhead is connected to the power head through a certain number of drill rods, and adjacent drill rods are fixed together by threaded connections. The length and number of drill rods determine the drilling depth.

[0042] The rod unloading device of this utility model embodiment includes a first engaging component 100, a second engaging component 200, and a telescopic component 300. The first engaging component 100 is mounted on the stabilizing rod 400, and the second engaging component 200 is mounted on the roller cone drill bit 500. The telescopic component 300 is used to drive the first engaging component 100 and the second engaging component 200 to move relative to each other, so that the roller cone drill bit 500 and the stabilizing rod 400 are disengaged. Compared with using conventional tools to disengage the roller cone drill bit 500 and the stabilizing rod 400, the rod unloading device of this embodiment can greatly improve the efficiency of disengaging the roller cone drill bit 500 and the stabilizing rod 400, thereby improving construction efficiency and reducing construction costs. The following is in conjunction with the appendix... Figures 1 to 3 The rod unloading device of this embodiment will be described in detail.

[0044] Reference Figure 1 , Figure 2 As shown, the outer peripheral wall of the stabilizer bar 400 is provided with multiple grooves 410. The shape of the first limiting part 113 matches the shape of the groove 410, and the first locking plate assembly 110 is correspondingly provided with multiple first limiting parts 113. When the first fitting assembly 100 is installed on the stabilizer bar 400, the multiple first limiting parts 113 correspond one-to-one with the multiple grooves 410 on the outer peripheral wall of the stabilizer bar 400, thereby increasing the contact area between the first locking plate assembly 110 and the stabilizer bar 400, making it easier for the first fitting assembly 100 to apply torque to the stabilizer bar 400 and drive the stabilizer bar 400 to rotate around its own axis. Similarly, referring to... Figure 1 , Figure 3 As shown, the outer peripheral wall of the roller cone drill bit 500 is provided with multiple semi-through grooves 510. The shape of the second limiting part 213 matches the semi-through groove 510, and multiple second limiting parts 213 are provided corresponding to the semi-through grooves 510. When the second fitting assembly 200 is installed on the roller cone drill bit 500, the multiple second limiting parts 213 correspond one-to-one with the multiple semi-through grooves 510 of the roller cone drill bit 500, thereby increasing the contact area between the second chuck assembly 210 and the roller cone drill bit 500, making it easier for the second fitting assembly 200 to apply torque to the roller cone drill bit 500. (Refer to...) Figure 1 As shown, the movable end 320 of the telescopic component 300 in this embodiment extends out and can transmit torque to the stabilizer bar 400 through the first fitting component 100 and to the roller cone drill bit 500 through the second fitting component 200, thereby causing the stabilizer bar 400 and the roller cone drill bit 500 to rotate towards each other and disengage. The structure is simple and easy to use, which can greatly improve the efficiency of disengaging the roller cone drill bit 500 from the stabilizer bar 400, thereby improving construction efficiency and reducing construction costs.
