Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to a drilling trolley. Background Art

[0002] A rock drilling rig (also called a drilling rig) is a rock drilling equipment used in tunnel and underground engineering projects using the drill and blast method. It can move and support multiple rock drills to perform drilling operations simultaneously. The working mechanism is mainly composed of a thruster, a drill arm, a rotary mechanism, and a translation mechanism.

[0003] The drill arm of the drilling trolley is usually equipped with a drill rod and a drill bit, and a coolant nozzle is usually provided at the end of the drill bit. A coolant pipe that penetrates the drill rod is provided near one end of the drill rod.

[0004] There are drilling trolleys in the prior art. For example, a Chinese invention patent application with publication number CN115263197A discloses a drilling trolley positioning marking structure, including a main arm, a guide groove is arranged on the main arm, the guide groove is slidably connected to a propulsion mechanism, the propulsion mechanism is connected to a hydraulic cylinder, a motor is arranged on the propulsion mechanism, the motor is connected to a drill rod mechanism, and the drill rod mechanism is screwed to a propulsion beam locator with an anti-friction function. Since the drill rod body is close to the guide column, the rotation of the drill rod body causes the guide column to drive the guide sleeve body to rotate along the inner ring of the bearing. The rotation of the guide sleeve body offsets the friction force generated by the rotation of the drill rod body and the guide column, thereby avoiding friction causing wear between the drill rod body and the guide column. At the same time, the movement of the drill rod body drives the guide column to roll. The rolling of the guide column not only guides the movement of the drill rod body, but is also beneficial to the movement of the drill rod body. Secondly, since the drill rod body is slidably connected to the guide column, the wear of the drill rod body and the guide column caused by friction is further avoided.

[0005] However, the above patent still has certain shortcomings. When the drill bit finishes drilling, the drill bit is pulled and retracted into the drill arm through a propulsion device (for example, a hydraulic rod). Since the drill bit is very likely to generate a large amount of rock chips and coolant during long-term operation, a large amount of rock chip nodules will adhere to the outside of the drill rod. If the drill bit and the drill rod are not cleaned in time, in the subsequent drilling process, the rock chips and other residues on the drill bit and the drill rod may accumulate on the hole wall or between the drill tools, which is very likely to cause the drill to get stuck, thereby affecting the construction progress and increasing the difficulty of handling.

[0043] The two magnetic flip members 39 are symmetrically arranged about the transverse center axis of the casing 32 .

[0044] The nozzle assembly includes multiple groups of first nozzles 421 fixed on the sleeve 32, each group of first nozzles 421 includes multiple first nozzles 421, and each group of first nozzles 421 extends into the interior of the sleeve 32, and each first nozzle 421 is commonly fixed with a first connecting tube 42 at one end away from the drill bit body 131, and each magnetic flip member 39 is fixed with multiple groups of second nozzles 431, and each group of second nozzles 431 is commonly fixed with a second connecting tube 43 at one end away from the drill bit body 131, and the multiple first connecting tubes 42, the multiple second connecting tubes 43 and the multiple third nozzles 45 are all connected to the interior of the water cavity 411.

[0046] When the drilling of the drill bit body 131 is finished, the water pump body 44 and the motor body 12 are started, and the hydraulic rod is started at the same time to drive the receiving seat 11 to slide inside the drill arm body 1, and drive the drill rod body 13 and the drill bit body 131 above it to move toward the side of the hydraulic rod. When the hydraulic rod drives the drill bit body 131 from the outside of the two magnetic flip parts 39 to between the two magnetic flip parts 39, the drill bit body 131 close to the second inner ring 35 can push the second inner ring 35 to slide, and drive the two connecting rods 34 fixedly connected to the second inner ring 35 to move, and then drive the first inner ring 33 fixed with the two connecting rods 34 and the ring 36 sleeved on the outside of the first inner ring 33 to slide, and then drive the outer fixed rod 37 fixedly connected to the ring 36 to move, thereby pulling the transmission rotating rod 38 rotatably connected to the outer fixed rod 37 to rotate around the contact position with the side fixed plate 391, and then pull the two rotating rods around the casing The magnetic flip member 39 connected to the connecting rod 32 is flipped, and the torsion spring between the magnetic flip member 39 and the casing 32 is compressed. When the side of the first inner ring 33 away from the connecting rod 34 contacts the inner wall of the casing 32 away from the magnetic flip member 39, the two magnetic flip members 39 can be flipped to a mutually contacting position, and at the same time, under the action of a pair of magnetic blocks, the two can be tightly attached to each other. At the same time, starting the water pump body 44 can allow the detergent to enter the interior of the pouring seat 41, and the pressurization of the water pump body 44 can allow the detergent to enter the interior of the multiple first connecting pipes 42 and the multiple second connecting pipes 43 at the same time, and then splash out through the multiple groups of first nozzles 421, the multiple groups of second nozzles 431 and the third nozzle 45 respectively. At the same time, the starting of the motor body 12 can drive the drill rod body 13 and the drill bit body 131 to rotate synchronously, which can fully rinse and clean the drill rod body 13 and the drill bit body 131.

[0047] When the drill bit body 131 needs to perform drilling operations, the hydraulic rod can be started to make the receiving seat 11 slide toward the drill cleaning seat 31, thereby driving the motor body 12, the drill rod body 13 and the drill bit body 131 installed on the top of the receiving seat 11 to move. In this process, the drill bit body 131 close to the magnetic flip member 39 can contact the inner side of the two magnetic flip members 39, and push the two magnetic flip members 39 to rotate around the connection position with the port of the casing 32, and at the same time, the two magnetic flip members 39 can be made to rotate. The two magnetic flip members 39 are separated from each other. When the two magnetic flip members 39 are completely separated, the magnetic flip members 39 can rotate around the connection position with the port of the casing 32 under the action of the torsion spring force, and the outer surface of the magnetic flip member 39 is tightly attached to the outer wall of the casing 32. At this time, the magnetic flip member 39 is completely separated from the drill bit body 131 and the drill rod body 13, thereby avoiding the situation where the drill bit body 131 is difficult to operate normally due to the contact between the magnetic flip member 39 and the drill bit body 131.

[0048] In this embodiment, the drill rod cleaning assembly 2 includes a drill rod limiter 21 fixed to the top of the fixed plate 16, and a mounting ring 22 is fixedly provided on the outer wall of the drill rod limiter 21 away from the motor body 12, and the mounting ring 22 is sleeved on the outside of the drill rod body 13, and a plurality of cleaning scrapers 23 are fixedly provided on the side of the mounting ring 22 away from the outer wall of the drill rod limiter 21, and the plurality of cleaning scrapers 23 are distributed in a circular array, and the plurality of cleaning scrapers 23 are close to the outer wall of the drill rod body 13 on the side close to the drill rod body 13, and each cleaning scraper 23 is provided with an inclined surface on one side, and each cleaning scraper 23 is provided with a vertical surface on the other side.

[0049] The motor body 12 is connected to the drill rod body 13 via a coupling, the drill rod stopper 21 is connected to the drill rod body 13 via a bearing, and a guide groove matching the receiving seat 11 is provided inside the drill arm body 1 .

[0050] When the drill bit body 131 finishes drilling, the hydraulic rod is started to drive the receiving seat 11 to slide inside the drill arm body 1, and at the same time drives the motor body 12, the drill rod body 13 and the drill bit body 131 above it to move toward the side of the hydraulic rod. At the same time, the motor body 12 is started to drive the drill rod body 13 at its output end to rotate synchronously with the drill bit body 131. Since the inner wall of the cleaning scraper 23 is in close contact with the outer wall of the drill rod body 13, the outer wall of the drill rod body 13 first contacts with the inclined surface of the cleaning scraper 23, and then contacts with the outer wall of the cleaning scraper 23. In vertical surface contact, multiple cleaning scrapers 23 can scrape off the rock cuttings nodules on the outer wall of the drill rod body 13. At the same time, the water pump body 44 is started to draw the cleaning agent into the pouring seat 41. Under the pressurized action of the water pump body 44, the cleaning agent in the water cavity 411 can be pushed and sprayed out by the third nozzle 45, thereby softening the rock cuttings nodules adhered to the outer wall of the drill rod body 13 and scraping them off, preventing the rock cuttings adhered to the outer wall of the drill rod body 13 from entering the bearing between the drill rod body 13 and the drill rod limiter 21.

[0051] The working principle of the device is as follows: the hydraulic rod is started to drive the receiving seat 11 to slide inside the drill arm body 1, and at the same time, the motor body 12, the drill rod body 13 and the drill head body 131 above it are driven to move toward the side of the hydraulic rod, and at the same time, the motor body 12 is started to drive the drill rod body 13 at its output end and the drill head body 131 to rotate synchronously. Since the inner wall of the cleaning scraper 23 is in close contact with the outer wall of the drill rod body 13, the outer wall of the drill rod body 13 first contacts with the inclined surface of the cleaning scraper 23, and then contacts with the vertical surface of the cleaning scraper 23. Surface contact, multiple cleaning scrapers 23 can scrape off the rock cuttings nodules on the outer wall of the drill rod body 13. At the same time, the water pump body 44 is started to draw the cleaning agent into the pouring seat 41. Under the pressurized action of the water pump body 44, the cleaning agent in the water cavity 411 can be pushed and sprayed out by the third nozzle 45, thereby softening the rock cuttings nodules adhered to the outer wall of the drill rod body 13 and scraping them off, preventing the rock cuttings adhered to the outer wall of the drill rod body 13 from entering the bearing between the drill rod body 13 and the drill rod limiter 21.

[0052] When the hydraulic rod drives the drill body 131 from the outside of the two magnetic flipping members 39 to between the two magnetic flipping members 39, the drill body 131 close to the second inner ring 35 can push the second inner ring 35 to slide, and drive the two connecting rods 34 fixedly connected to the second inner ring 35 to move, and then drive the first inner ring 33 fixed with the two connecting rods 34 and the sleeve ring 36 sleeved on the outside of the first inner ring 33 to slide, and then drive the outer fixing rod 37 fixedly connected to the sleeve ring 36 to move, thereby pulling the transmission rotating rod 38 rotatably connected to the outer fixing rod 37 to rotate around the contact position with the side fixing plate 391, and then pull the two magnetic flipping members 39 rotatably connected to the casing 32 to flip, at this time, the torsion spring between the magnetic flipping member 39 and the casing 32 is compressed, when the first When the side of the inner ring 33 away from the connecting rod 34 contacts the inner wall of the side of the casing 32 away from the magnetic flip member 39, the two magnetic flip members 39 can be flipped to a position where they contact each other, and at the same time, under the action of a pair of magnetic blocks, the two can be tightly attached to each other. At the same time, starting the water pump body 44 can allow the detergent to enter the interior of the pouring seat 41, and the pressurization of the water pump body 44 can allow the detergent to enter the multiple first connecting pipes 42 and the multiple second connecting pipes 43 at the same time, and then splash out through the multiple groups of first nozzles 421, the multiple groups of second nozzles 431 and the third nozzle 45 respectively. At the same time, the starting of the motor body 12 can drive the drill rod body 13 and the drill bit body 131 to rotate synchronously, which can fully rinse and clean the drill rod body 13 and the drill bit body 131.
