[0044] Example 1

[0045] like Figure 1 The figure shows a rock drill propulsion device disclosed in the present embodiment, comprising a propulsion beam 1 and a propulsion mechanism, wherein the propulsion mechanism comprises a slide 2, a first sprocket 3, a second sprocket 4, a transmission chain 5, a tensioner 6 and a driving member 7. The first sprocket 3 is rotatably connected to the first end of the propulsion beam 1 through a wheel frame, the second sprocket 4 is rotatably connected to the second end of the propulsion beam 1 through a wheel frame, and the slide 2 is slidably connected to the propulsion beam 1. The first end of the transmission chain 5 is connected to the slide 2 after bypassing the first sprocket 3, and the second end of the transmission chain 5 is connected to the slide 2 after bypassing the second sprocket 4, and the transmission chain 5 is meshed with both the first sprocket 3 and the second sprocket 4. The driving member 7 can be a hydraulic motor or an electric motor, and the driving member 7 is connected to the first sprocket 3 and / or the second sprocket 4 to drive the first sprocket 3 and / or the second sprocket 4 to rotate, thereby driving the slide 2 to move forward or backward on the propulsion beam 1. The tensioning member 6 is connected to the first sprocket 3 and / or the second sprocket 4 for driving the first sprocket 3 and / or the second sprocket 4 to move along the length direction of the propulsion beam 1, so that the spacing between the first sprocket 3 and the second sprocket 4 is adjustable, which can keep the transmission chain 5 in a tensioned state during the propulsion process and can also be quickly loosened when the transmission chain 5 is replaced, thereby improving the replacement efficiency of the transmission chain 5.

[0046] refer to Figure 2 , Figure 3The slide 2 includes a rock drill mounting member 201, a rock drill positioning member 202, and two spaced apart slides 203. The two slides 203 are mainly used to assemble with the host equipment on the propulsion beam 1 to realize the sliding guidance of the slide 2 on the propulsion beam 1. The rock drill mounting member 201 is welded or bolted to one end of the top of the two slides 203, and the rock drill positioning member 202 is welded or bolted to the other end of the top of the two slides 203, which is mainly used to fix the rock drill 10 on the slide 2. A first connecting member 204 is provided at the bottom of the rock drill mounting member 201, and a second connecting member 205 is provided at the bottom of the rock drill positioning member 202. The first connecting member 204 and the second connecting member 205 are located between the two slides 203, and are mainly used to connect the ends of the transmission chain 5. By arranging the rock drill mounting member 201 and the rock drill positioning member 202 on two spaced apart slides 203, the free space between the two slides 203 can be used as an insertion space for the transmission chain 5. By cooperating with the first connecting member 204 and the second connecting member 205 at the bottom of the rock drill mounting member 201 and the rock drill positioning member 202, the transmission chain 5 on the slide seat 2 can be replaced without disassembling the rock drill 10, thereby effectively improving the construction efficiency.

[0047] In the specific implementation process, the rock drill mounting member 201 can be a rock drill mounting flange, and the rock drill positioning member 202 can be a rock drill positioning plate. Figure 4 , Figure 5 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.

[0048] As a preferred embodiment, the first connecting member 204 and / or the second connecting member 205 is a pin rod with a flange structure, and in coordination therewith, the first end of the transmission chain 5 is fixedly connected with a first wire rope loop 501, and the second end of the transmission chain 5 is fixedly connected with a second wire rope loop 502. When connected, the first wire rope loop 501 is sleeved on the first connecting member 204, and the second wire rope loop 502 is sleeved on the second connecting member 205, so that the first wire rope loop 501 and the second wire rope loop 502 can be blocked by the flange at the end of the pin rod so that they are not easy to slide out, and self-locking is achieved to ensure the stability of the connection of the transmission chain 5. At the same time, when replacing the transmission chain 5, it is only necessary to loosen the transmission chain 5 so that it is no longer tensioned, and the transmission chain 5 can be removed from the first connecting member 204 and the second connecting member 205. After removing the old transmission chain 5 and installing the new transmission chain 5, the tension can be completed to complete the replacement of the transmission chain 5, which brings great convenience to the replacement of the transmission chain 5.

[0049] It is worth noting that in the specific application process, the first connecting member 204 and / or the second connecting member 205 are not limited to using a pin rod with a flange structure, and a screw rod can also be directly used as the first connecting member 204 and / or the second connecting member 205. That is, when connecting, the first wire rope loop 501 and the second wire rope loop 502 are inserted into the screw rod and then tightened with a nut to achieve a fixed connection between the transmission chain 5 and the slide seat 2.

[0050] In this embodiment, the tensioning member 6 can be an oil cylinder, an air cylinder, or a screw nut pair. The first transmission seat 8 and the second transmission seat 9 are slidably connected on the propulsion beam 1. The wheel frame of the first sprocket 3 is set on the first transmission seat 8, and the wheel frame of the second sprocket 4 is set on the second transmission seat 9. The number of tensioning members 6 is two, one of which is connected to the first transmission seat 8 to drive the first transmission seat 8 to slide along the propulsion beam 1; the other tensioning member 6 is connected to the second transmission seat 9 to drive the second transmission seat 9 to slide along the propulsion beam 1. It is worth noting that in the specific application process, only the first transmission seat 8 or only the second transmission seat 9 can be set, and the same tensioning effect can be achieved.

[0051] refer to Figure 6 More than two propulsion mechanisms can be arranged in the rock drill propulsion device, that is, the actions of multiple rock drills 10 can be controlled, and the structure is simple and the operation is convenient. Among them, the first sprocket 3 in each propulsion mechanism is arranged on the same first connecting seat, and / or the second sprocket 4 in each propulsion mechanism is arranged on the same second connecting seat, so that each propulsion mechanism can share a set of tensioning members 6.

[0052] Example 2

[0053] Based on the rock drill propulsion device in Example 1, this embodiment further discloses a rock drilling trolley on which the rock drill propulsion device in Example 1 is installed.
