Description
Technical Field
[0001] The utility model relates to the technical field of rope coring, in particular to a broken rock mass rope coring device. Background Art
[0002] Rope coring refers to drilling into the rock mass through a drill rod. After the core in the rock and mineral fills the core tube, there is no need to lift the drill. Instead, the core tube after collecting the core from the drill rod is lifted out of the ground with the help of a rope retracting device and a salvage tool. This can reduce the drilling time and drilling costs. At the same time, the high degree of automation can reduce the labor intensity of the staff.
[0003] However, in the prior art, when the salvage tool works in the drill pipe, it will generate friction with the inner wall of the drill pipe, which brings inconvenience to the rope lifting of the salvage tool under the friction force, and it is easy to cause the salvage tool to shake in the drill pipe, thereby driving the core tube to shake, and there is a risk of the core tube detaching from the salvage tool. Secondly, the shaking process is easy to cause the loss of the core in the core tube, reducing the coring efficiency. For this reason, a broken rock rope coring device is proposed to reduce the friction of the salvage tool between the drill pipe and prevent the salvage tool from shaking in the drill pipe. At the same time, a shock-absorbing component is provided to reduce the impact of the shaking on the core tube, thereby preventing the core tube from detaching from the salvage tool and causing the loss of the core in the core tube due to the shaking, thereby improving the coring efficiency.

The upper end of the telescopic rod is installed on the top of the mounting tube, and the lower end is fixedly connected to the mounting tube. A clamping cylinder is connected, the shock-absorbing spring sleeve is arranged on the telescopic rod and is located between the top of the mounting cylinder and the clamping cylinder, the clamping mechanism is arranged in the clamping cylinder, the clamping mechanism is composed of two clamping arms, two magnets and two electromagnets, a horizontal rotating shaft is arranged in the clamping cylinder, the two clamping arms are cross-shaped hinges and are rotatably connected to the rotating shaft, the two magnets are respectively fixedly installed on the top of a clamping arm, the bottom ends of the two clamping arms are provided with claws for hooking the spear head, a mounting plate is provided at the middle of the upper ends of the two clamping arms at the top of the clamping cylinder, the two electromagnets are respectively installed on the two side surfaces of the mounting plate, and the electromagnets are respectively attracted to the magnets at the top ends of the clamping arms on the adjacent sides.

[0020] like Figure 1-3In the present embodiment, a broken rock rope coring device comprises a drill rod 1, a core tube 2, and a salvage tool 3. The core tube 2 is arranged at the bottom of the drill rod 1, and a spearhead 21 is fixedly arranged at the top of the core tube 2. The salvage tool 3 is slidably connected to the drill rod 1. The salvage tool 3 is composed of a mounting tube 4, a shock absorbing mechanism 5, and a clamping mechanism 6. A plurality of first balls 41 are movably arranged on the outer surface of the mounting tube 4, and the first balls 41 are movably mounted on the mounting cavity 43 opened in the mounting tube 4 through a first spring 42. The first balls 41 on the outer surface of the mounting tube 4 are slidably connected to the inner wall of the drill rod 1. The shock absorbing mechanism 5 is arranged at the top of the mounting tube 4. The shock absorbing mechanism 5 is composed of a telescopic rod 51 and a shock absorbing spring 52. The upper end of the telescopic rod 51 is mounted on the top of the mounting tube 4, and the lower end is fixedly connected with a clamping tube 7. The shock-absorbing spring 52 is sleeved on the telescopic rod 51 and is located between the top of the mounting tube 4 and the clamping tube 7. The clamping mechanism 6 is arranged in the clamping tube 7. The clamping mechanism 6 is composed of two clamping arms 61, two magnets 62, and two electromagnets 63. A horizontal rotating shaft 71 is provided in the clamping tube 7. The two clamping arms 61 are cross-shaped hinges and are rotatably connected to the rotating shaft 71. The two magnets 62 are respectively fixedly mounted on the top of a clamping arm 61, and the bottom ends of the two clamping arms 61 are provided with hook claws 611 for hooking the spear head 21. A mounting plate 72 is provided at the middle of the upper ends of the two clamping arms 61 at the top of the clamping tube 7. The two electromagnets 63 are respectively mounted on the two side surfaces of the mounting plate 72, and the electromagnets 63 are respectively attracted to the magnets 62 at the top of the clamping arms 61 on the adjacent sides.
[0021] Through the above technical solution, when the core tube 2 is salvaged, the salvage tool 3 is placed in the drill pipe 1, and the salvage tool 3 is connected to the external winding mechanism through the rope 8. After the salvage tool 3 is placed in the drill pipe 1, the rope 8 is lowered so that the salvage tool 3 moves downward along the inner wall of the drill pipe 1. The installation tube 4 is slidably connected to the inner wall of the drill pipe 1 through the first ball 41, so that the clamping mechanism 6 can be located directly above the spearhead 21 at the top of the core tube 2, which is convenient for clamping. The design of the first ball 41 on the surface of the installation tube 4 reduces The friction between the mounting tube 4 and the inner wall of the drill rod 1 is reduced, so that the external winding mechanism can more conveniently lift the salvage tool 3 through the rope 8. At the same time, the first ball 41 is installed in the mounting cavity 43 in the mounting tube 4 through the first spring 42, so that the first ball 41 has elasticity. When the drill rod 1 shakes, the shaking force will be transmitted to the first ball 41. Since the first ball 41 has elasticity, it can reduce the impact of the shaking of the drill rod 1 on the mounting tube 4. When the salvage tool 3 moves to the core tube 2 When the top is reached, the spearhead 21 at the top of the core tube 2 contacts the lower ends of the two hinged clamping arms 61 in the clamping mechanism 6. Under the action of the gravity of the salvaging tool 3, the spearhead 21 pushes open the lower ends of the two hinged clamping arms 61, so that the claw hook 611 hooks the spearhead 21. At this time, under the action of the mutual attraction between the electromagnet 63 and the magnet 62 on the adjacent side in the mounting plate 72, the upper ends of the two clamping arms 61 are clamped, and then the lower claw hook 21 clamps the spearhead 21 at the top of the core tube 2, making it difficult for it to be self- When the clamping mechanism 6 falls off, after the salvage tool 3 clamps the core tube 2, the rope 8 is reeled back to drive the salvaging tool 3 to be lifted up. Since the clamping mechanism 6 is installed in the clamping tube 7, and a shock absorbing mechanism 5 is installed between the clamping tube 7 and the installation tube 4, when shaking occurs during the pulling process, the setting of the telescopic rod 51 and the shock absorbing spring 52 can reduce the impact on the clamping tube 7, thereby reducing the impact on the clamping mechanism 6, and thus it is not easy for the core tube 2 to fall off and the internal core to be lost, thereby improving the extraction efficiency.
[0022] Preferably, a connection seat 44 for connecting the rope 8 is fixedly provided at the top axis of the installation tube 4 .
[0023] Through the above technology, the connecting seat 44 is convenient for connecting the rope 8, and at the same time ensures that the force of the rope 8 is always located at the axis when the installation tube 4 is driven to rise and fall, thereby ensuring the stability of the installation tube 4 rising and falling.
[0024] Preferably, a plurality of second balls 73 are movably provided on the outer surface of the clamping tube 7 , and the second balls 73 are slidably connected to the inner wall of the mounting tube 4 , and the installation method of the second balls 73 in the clamping tube 7 is the same as the installation method of the first balls 41 in the mounting tube 4 .
[0025] Through the above technical solution, the second ball 73 enables the clamping tube 7 and the mounting tube 4 to be in a sliding connection, thereby preventing collision between the mounting tube 4 and the clamping tube 7. At the same time, through the elasticity of the second ball 73, the clamping tube 7 is not easily affected when the mounting tube 4 shakes, thereby ensuring the stability of the clamping mechanism 6.
[0026] Preferably, the bottom ends of the two clamping arms 61 are located outside the bottom end of the clamping cylinder 7 .
[0027] Through the above technical solution, the arrangement of the clamping cylinder 7 does not hinder the clamping operation at the bottom ends of the two clamping arms 61 in the clamping mechanism 6 .
[0028] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; the technology not described in detail in the present invention is implemented with the existing technology.
