[0051] Example 1

[0052] like Figures 1 to 5The present embodiment shows a rock drill slide, which mainly includes a rock drill installation mechanism and two spaced connection plates 1, the two connection plates 1 are mainly used to assemble with the main equipment on the propulsion beam, and realize the sliding guide of the rock drill slide on the propulsion beam. The rock drill installation mechanism is connected to the top of the two connection plates 1, and is mainly used to fix the rock drill 6 on the rock drill slide. The bottom of the rock drill installation mechanism is provided with a first connection member 2 and a second connection member 3, and the first connection member 2 and the second connection member 3 are located between the two connection plates 1, and are mainly used to connect the ends of the steel wire rope 7. By arranging the rock drill installation mechanism on the two spaced connection plates 1, the free space between the two connection plates 1 can be used as the insertion space of the steel wire rope 7, and the first connection member 2 and the second connection member 3 at the bottom of the rock drill installation mechanism can realize the replacement of the steel wire rope 7 on the rock drill slide without disassembling the rock drill 6, thereby effectively improving the construction efficiency.

[0053] In this embodiment, the rock drill installation mechanism includes a rock drill installation member 4 and a rock drill positioning member 5. The rock drill installation member 4 is welded or bolted to one end of the top of the two connecting plates 1, the rock drill positioning member 5 is welded or bolted to the other end of the top of the two connecting plates 1, the first connecting member 2 is arranged at the bottom of the rock drill installation member 4, and the second connecting member 3 is arranged at the bottom of the rock drill positioning member 5.

[0054] In the specific implementation process, the rock drill mounting member 4 can be a rock drill mounting flange, and the rock drill positioning member 5 can be a rock drill positioning plate, that is, Figure 6 , Figure 7 As for the specific implementation structure of the rock drill mounting flange and the rock drill positioning plate, they are conventional designs in the art and will not be described in detail in this embodiment.

[0055] As a preferred embodiment, the first connecting member 2 and / or the second connecting member 3 is a pin rod with a flange structure. When connected, the end of the wire rope 7 is inserted into the pin rod and is blocked by the flange at the end of the pin rod so that it is not easy to slide out, thereby achieving self-locking and ensuring the stability of the connection of the wire rope 7. At the same time, when replacing the wire rope 7, it is only necessary to loosen the wire rope 7 so that it is no longer tensioned, and then the wire rope 7 can be removed from the first connecting member 2 and the second connecting member 3. After removing the old wire rope and installing the new wire rope, it can be tensioned to complete the replacement of the wire rope, which greatly facilitates the replacement of the wire rope 7.

[0056] It is worth noting that in the specific application process, the first connecting member 2 and / or the second connecting member 3 are not limited to the pin rod with a flange structure, and a screw rod can also be directly used as the first connecting member 2 and / or the second connecting member 3, that is, when connecting, the screw rod is rotated to tighten the end of the wire rope 7 to achieve a fixed connection between the wire rope 7 and the rock drill slide.

[0057] Example 2

[0058] like Figure 8 , Fig. 9 The figure shows a wire rope propulsion mechanism disclosed in the present embodiment, including a propulsion beam, a first pulley 8, a second pulley 9, a third pulley 10, a fourth pulley 11, a double-wheel movable pulley 12, a first wire rope 13, a second wire rope 14, a first rock drill slide 15 and a second rock drill slide 16. Among them, the first rock drill slide 15 and the second rock drill slide 16 are both the rock drill slides of Embodiment 1.

[0059] The first pulley 8 and the second pulley 9 are respectively connected to the first end of the propulsion beam through the wheel frame for symmetrical rotation, and the third pulley 10 and the fourth pulley 11 are respectively connected to the second end of the propulsion beam through the wheel frame for symmetrical rotation, that is, the first pulley 8, the second pulley 9, the third pulley 10, and the fourth pulley 11 are all fixed pulleys. The first rock drill slide 15 and the second rock drill slide 16 are respectively connected to the propulsion beam for sliding, and the double-wheel movable pulley 12 is connected to the propulsion beam through the wheel frame, and the wheel frame of the double-wheel movable pulley 12 can slide along the length direction of the propulsion beam, and the double-wheel movable pulley 12 is located between the first rock drill slide 15 and the second rock drill slide 16. The double-wheel movable pulley 12 has a coaxial first wheel structure and a second wheel structure, the first end of the first steel wire rope 13 is connected to the first connecting piece on the first rock drill slide 15, and the second end is connected to the first connecting piece on the second rock drill slide 16 after passing through the first pulley 8, the first wheel structure, and the second pulley 9 in sequence. The first end of the second steel wire rope 14 is connected to the second connecting piece on the first rock drill slide 15, and the other end is connected to the second connecting piece on the second rock drill slide 16 after passing through the third pulley 10, the second wheel structure, and the fourth pulley 11 in sequence. Therefore, under the action of the first steel wire rope 13 and the second steel wire rope 14, as the double-wheel movable pulley 12 slides along the length direction of the propulsion beam, the first rock drill slide 15 and the second rock drill slide 16 can be driven to slide synchronously along the length direction of the propulsion beam, thereby realizing the synchronous operation of the two groups of rock drills.

[0060] In the specific implementation process, the side of the first rock drill slide 15 is provided with a first boss 17, the side of the second rock drill slide 16 is provided with a second boss 18, and a limit plate 19 is slidably connected to the propulsion beam, the limit plate 19 is located between the first rock drill slide 15 and the second rock drill slide 16, and the two ends of the limit plate 19 are respectively provided with a first slot and a second slot. The propulsion beam is provided with a switching drive 20, such as a cylinder, a screw nut pair, etc., which can drive the limit plate 19 to slide on the propulsion beam. Under the action of the switching drive 20, when the first boss 17 is embedded in the first slot, the second boss 18 is separated from the second slot. At this time, the first rock drill slide 15 is relatively fixed to the propulsion beam, so that the second rock drill slide 16 can slide independently on the propulsion beam. Similarly, under the action of the switching drive 20, the second boss 18 can be inserted into the second slot while the first boss 17 is separated from the first slot. At this time, the second rock drill slide 16 is relatively fixed to the propulsion beam, so that the first rock drill slide 15 can slide independently on the propulsion beam. Of course, the first boss 17 can also be separated from the first slot and the second boss 18 can be separated from the second slot under the action of the switching drive 20. That is, under the action of the limit plate 19 and the switching drive 20, the two rock drills on the propulsion beam can work synchronously or selectively.

[0061] As a preferred embodiment, a tensioning assembly 21 is further provided on the propulsion beam, and the tensioning assembly 21 is transmission-connected with the first pulley 8 and the second pulley 9 to drive the first pulley 8 and the second pulley 9 to move along the length direction of the propulsion beam; and / or the tensioning assembly 21 is transmission-connected with the third pulley 10 and the fourth pulley 11 to drive the third pulley 10 and the fourth pulley 11 to move along the length direction of the propulsion beam. With the displacement of the first pulley 8, the second pulley 9 and / or the third pulley 10 and the fourth pulley 11, the first steel wire rope 13 and the second steel wire rope 14 can be tensioned or loosened. Combined with the structural design of the rock drill slide in Example 1, the replacement speed of the steel wire rope can be further improved, thereby improving the construction efficiency.

[0062] Specifically, the tensioning assembly 21 can be an oil cylinder, an air cylinder or a screw nut pair arranged on the propulsion beam. A first slide 22 is slidably connected to the propulsion beam, and the wheel frames of the first pulley 8 and the second pulley 9 are both arranged on the first slide 22, and the tensioning assembly 21 is connected to the first slide 22 by transmission to drive the first slide 22 to slide along the propulsion beam. And / or a second slide is slidably connected to the propulsion beam, and the wheel frames of the third pulley 10 and the fourth pulley 11 are both arranged on the second slide, and the tensioning assembly 21 is connected to the second slide by transmission to drive the second slide to slide along the propulsion beam. It is worth noting that although only the first slide 22 is provided in the present embodiment, in the specific application process, only the second slide may be provided, or the first slide 22 and the second slide may be provided at the same time.

[0063] In this embodiment, a driving assembly 23 is also provided on the propulsion beam, and is transmission-connected to the wheel frame of the double-wheel movable pulley 12 to drive the double-wheel movable pulley 12 to move along the length direction of the propulsion beam. The driving assembly 23 can also be an oil cylinder, an air cylinder, or a screw nut pair.
