Technical Field
[0001] The present invention belongs to the technical field of drilling rig equipment, and specifically relates to a rotary drilling rig. Background Art
[0002] A rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for construction in soil layers such as sandy soil, cohesive soil, and silty soil, and is widely used in various foundation construction operations such as cast-in-place piles, diaphragm walls, and foundation reinforcement. Generally, it adopts a hydraulic crawler telescopic chassis, a self-lifting and foldable drill mast, a telescopic drill pipe, with vertical automatic detection and adjustment, digital display of hole depth, etc. The whole machine is generally controlled by hydraulic pilot control and load sensing, and has the characteristics of light and comfortable operation.
[0003] However, in the prior art, due to different usage requirements, the existing rotary drilling rig needs to replace different drill bits in different usage occasions and stages. During the actual construction process, for the safe and stable storage of the drill bit, it is mostly placed horizontally at a designated position. As a result, during the process of replacing the drill bit of the existing rotary drilling rig, the drill pipe is required to push and adjust the drill bit to a vertical state. During this process, the drill pipe is prone to damage during misoperation, and the actual operation difficulty is relatively large. At the same time, the bottom structure of the drill bit is prone to extrusion and collision damage during the pushing and adjusting process, affecting the normal use of the drill bit, resulting in poor efficiency of actually replacing the drill bit of the existing rotary drilling rig. Summary of the Invention
[0004] The purpose of the present invention is to provide a rotary drilling rig that can conveniently replace the drill bit body, avoid damage to the drill pipe body and the drill bit body during the replacement process, and improve the actual replacement efficiency of the drill bit body.
[0005] The technical solution adopted by the present invention is as follows: A rotary drilling rig includes: a rig body, a drill bit body, and a connection mechanism. The connection mechanism is arranged on the rig body. The connection mechanism includes two sliding frames, a hanging plate, two sliding bars, a guiding component, and a winding component. On the outer surface of one side of each sliding frame, two hanging blocks are fixedly connected. The hanging plate is slidably sleeved between the outer surfaces of the four hanging blocks. The two sliding bars are both threadedly connected to the outer surface of one side of the hanging plate. The guiding component is arranged on the two sliding frames. The winding component is arranged on the hanging plate;
[0006] The drill bit body is arranged on the winding component.
[0007] Among them, the four hanging blocks are divided into two groups. Between the interiors of each group of hanging blocks, two connecting rods are slidably penetrated. One end of each connecting rod is threadedly connected with a connecting nut.
[0008] Among them, two sets of the guiding components are provided. Each set of the guiding components includes two pulleys, two supporting wheels, two adjusting bolts and two guiding pieces. The two pulleys are both rotatably connected to the inside of the corresponding sliding frame. The two supporting wheels are both rotatably connected to the outer surface of one side of the corresponding hanging block. The two adjusting bolts are fixedly connected to the outer surface of the other side of the corresponding sliding frame. The two guiding pieces are both slidably sleeved on the outer surface of the corresponding adjusting bolt.
[0009] Among them, a supporting piece is fixedly connected to the outer surface of the other side of each sliding frame on one side of the corresponding adjusting bolt. Two adjusting nuts are threadedly connected to the outer surface of each adjusting bolt.
[0010] Among them, the outer surface of one side of each guiding piece is in contact with the corresponding adjusting thread nut, and the outer surface of one side of each supporting piece is in contact with the outer surface of the corresponding guiding piece.
[0011] Among them, a first threaded hole is formed in the outer surface of one side of each hanging block, and four second threaded holes are formed in the outer surface of the other side of the hanging plate. A connecting bolt is threadedly connected to the inside of each second threaded hole and the inside of the corresponding first threaded hole.
[0012] Among them, the winding component includes a winch body, a fixed guiding wheel, two limiting frames, a moving guiding wheel and a limiting component. The fixed guiding wheel is rotatably connected between the opposite outer surfaces of the hanging plate. Each limiting frame is slidably sleeved on the outer surface of the corresponding sliding strip. The moving guiding wheel is rotatably connected between the opposite outer surfaces of the two limiting frames. The winch body is fixedly connected to the outer surface of the other side of the moving hanging plate. A traction rope body is wound around the output end of the winch body. The limiting component is arranged on the traction rope body.
[0013] Among them, the limiting component includes a hanging frame, a lifting frame, a lifting rod, a pushing block and two pressing blocks. The hanging frame is fixedly connected to one end of the traction rope body. The lifting frame is rotatably connected to the bottom of the hanging frame. The lifting rod is slidably inserted into the top of the lifting frame. The pushing block is fixedly connected to the bottom end of the lifting rod. The two pressing blocks are both slidably sleeved on the outer surface of the pushing block. The outer surface of one side of each pressing block is in contact with the inner wall of the drill bit body. A clamping block is fixedly connected to the outer surface of one side of each pressing block.
[0014] Among them, a connecting threaded hole is formed at one end of each sliding strip, and a plurality of positioning holes are equidistantly formed in the top of each sliding strip.
[0015] Among them, a positioning frame is fixedly connected to the top of each limiting frame. A positioning bolt slidably penetrates through the top surface inside each positioning frame. The bottom end of each positioning bolt slidably penetrates through the top of the corresponding limiting frame. The bottom end of each positioning bolt extends into the corresponding positioning hole. A resisting ring is sleeved on the outer surface of each positioning bolt. A limiting spring is slidably sleeved on the outer surface of each positioning bolt.
[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:
[0017] (1) In the present invention, during use, the bottom end of the drill mast body is moved above the drill bit body through the vehicle body, and then the winch body is controlled to start releasing the traction rope body, so that the limiting component is inserted into the connecting end of the drill bit body, enabling the two pressing blocks to be clamped inside the drill bit body through the clamping blocks. At this time, the winch body runs in the reverse direction to wind up the traction rope body. Under the support and guidance of the moving guide wheel and the fixed guide wheel, the traction rope body can gradually pull the hanger to a vertical state. During this process, the hanger cooperates with the lifting frame to pull the lifting rod outside the connecting end of the drill bit body, so that the lifting rod can drive the push block to move outside the connecting end of the drill bit body. Subsequently, the push block can squeeze the two side pressing blocks to closely fit the inner wall of the drill bit body during the movement. When the push block cannot move further under the extrusion of the pressing blocks, the continuous traction of the traction rope body enables the hanger to cooperate with the lifting frame, the lifting rod, the push block, the clamping block, and the pressing block to gradually pull the connecting end of the drill bit body to a vertical state until the drill bit body is completely separated from the ground. At this time, the existing cushion block is placed under the drill bit body, and at the same time, by rotating the horizontal angle of the drill bit, the connection direction between the bottom end of the drill pipe body and the connecting end of the drill bit body is made consistent. Then, by controlling the winch body, the drill bit body can smoothly fall to the top of the existing cushion block in a vertical state, and then the limiting component is removed. Furthermore, by maintaining the moving direction of the vehicle body, the drill pipe body can be conveniently moved above the connecting end of the drill bit body, and then the drill pipe can be conveniently connected to the drill bit body, enabling the equipment to efficiently replace the drill bit body. At the same time, the integrity of the drill pipe body and the drill bit body can be ensured, avoiding damage to the drill pipe body and the drill bit body, and enabling the equipment to efficiently realize its due functions.
[0018] (2) In the present invention, according to the actual specifications of the drill bit body, the positioning bolt is lifted, so that the positioning bolt can be disengaged from the corresponding positioning hole. At this time, under the position limitation of the sliding strip, the use position of the moving adjustment limiting frame is moved and adjusted, so that the moving guide wheel can move accordingly. Then, when moving to a position where the drill bit body is not likely to collide with the drill pipe body during suspension, by releasing the positioning bolt, the positioning bolt can be inserted into the positioning hole at this time through the limiting spring and the abutting ring to fix and limit the position of the limiting frame. At the same time, when the drill bit body is stably placed on the top of the existing cushion block, by knocking on the top of the lifting rod, the lifting rod can be made to quickly push down the push block, and then the gap between the push block and the pressing block is increased. At this time, the connection end inner wall of the pressing block and the drill bit body can be conveniently separated, so that the limiting component can be quickly separated from the drill bit body, facilitating the connection between the drill pipe body and the drill bit body, improving the actual replacement efficiency of the drill bit body. At the same time, when the drill bit body is in a suspended state, by controlling and adjusting the use height of the power head body, during the movement of the power head body, the sliding frame can move along with the power head body through the adjusting bolt and the guiding piece under the support of the pulley and the supporting wheel. Then, the sliding frame can drive the hanging plate and the sliding strip to move synchronously through the hanging block, and then the distance between the suspended drill bit body and the ground can be adjusted. Thus, the vehicle can conveniently carry the drill bit to move, facilitating the synchronous movement and transfer of the replaced drill bit body, and at the same time facilitating the placement of the existing cushion block, improving the actual use effect of the equipment.

The winding component includes a winch body 110, a fixed guiding wheel 111, two limiting frames 113, a moving guiding wheel 114 and a limiting component. The fixed guiding wheel 111 is rotatably connected between the opposite outer surfaces of the hanging plate 109. Each limiting frame 113 is respectively slidably sleeved on the outer surface of the corresponding sliding bar 112. The moving guiding wheel 114 is rotatably connected between the opposite outer surfaces of the two limiting frames 113. The winch body 110 is fixedly connected to the outer surface of the other side of the hanging plate 109. A traction rope body is wound around the output end of the winch body 110. The limiting component is arranged on the traction rope body. The limiting component includes a hanging frame 122, a lifting frame 121, a lifting rod 120, a pushing block 119 and two pressing blocks 117. The hanging frame 122 is fixedly connected to one end of the traction rope body. The lifting frame 121 is rotatably connected to the bottom of the hanging frame 122. The lifting rod 120 is slidably inserted into the top of the lifting frame 121. The pushing block 119 is fixedly connected to the bottom end of the lifting rod 120. The two pressing blocks 117 are both slidably sleeved on the outer surface of the pushing block 119. The outer surface of one side of each pressing block 117 is in contact with the inner wall of the drill bit body 3. A clamping block 118 is fixedly connected to the outer surface of one side of each pressing block 117. A connecting threaded hole is opened at one end of each sliding bar 112. A plurality of positioning holes are equidistantly opened at the top of each sliding bar 112. A positioning frame is fixedly connected to the top of each limiting frame 113.A positioning bolt 115 is slidably penetrated on the top surface of each positioning frame, and the bottom end of each positioning bolt 115 slides through the top of the corresponding limit frame 113, and the bottom end of each positioning bolt 115 extends to the inside of the corresponding positioning hole. A collar 116 is sleeved on the outer surface of each positioning bolt 115, and a limit spring is slidably sleeved on the outer surface of each positioning bolt 115. The bottom end of the drill mast body 202 is moved to the top of the drill bit body 3 through the vehicle body 201, and then the winch body 110 is controlled to start to release the traction rope body, and then the limit assembly is inserted into the connecting end of the drill bit body 3, so that the two pressure blocks 117 can be clamped into the inside of the drill bit body 3 through the clamping block 118. At this time, the winch body 110 is reversed to reel in the traction rope body, and the guide wheel 114 and the fixed wheel 118 are moved to the bottom of the drill mast body 202. Under the support and guidance of the fixed guide wheel 111, the traction rope body can gradually pull the hanger 122 to a vertical state. During this process, the hanger 122 cooperates with the lifting frame 121 to pull the lifting rod 120 toward the outside of the connecting end of the drill bit body 3, so that the lifting rod 120 can drive the push block 119 to move toward the outside of the connecting end of the drill bit body 3, and then the push block 119 can squeeze the pressure blocks 117 on both sides to fit tightly against the inner wall of the drill bit body 3 during the movement. When the push block 119 cannot continue to move under the squeezing of the pressure block 117, the continuous traction of the traction rope body enables the hanger 122 to cooperate with the lifting frame 121, the lifting rod 120, the push block 119, the clamping block 118 and the pressure block 117 to gradually pull the connecting end of the drill bit body 3 to a vertical state until the drill bit body is in a straight line. 3 is completely separated from the ground. At this time, the existing cushion block is placed under the drill bit body 3. At the same time, the horizontal angle of the drill bit is rotated to make the bottom end of the drill rod body 204 consistent with the connection end of the drill bit body 3. Then, by controlling the winch body 110, the drill bit body 3 can be steadily dropped to the top of the existing cushion block in a vertical state. Then, the limit assembly is taken out to maintain the moving direction of the vehicle body 201. The drill rod body 204 can be easily moved to the top of the connection end of the drill bit body 3, and then the drill rod can be easily connected to the drill bit body 3, so that the equipment can efficiently replace the drill bit body 3, and at the same time, the integrity of the drill rod body 204 and the drill bit body 3 can be ensured to avoid damage to the drill rod body 204 and the drill bit body 3, so that the equipment can The functions should be realized efficiently. At the same time, according to the actual specifications of the drill body 3, the positioning bolt 115 is lifted up so that the positioning bolt 115 can be separated from the corresponding positioning hole. At this time, the use position of the limit frame 113 is moved and adjusted under the position limit of the slide bar 112, so that the movable guide wheel 114 can follow the movement, and then move to ensure that the drill body 3 is not easy to collide with the drill rod body 204 when suspended. By releasing the positioning bolt 115, the positioning bolt 115 can be inserted into the positioning hole through the limit spring and the abutment ring 116 at this time, and then the position of the limit frame 113 is fixed and limited. At the same time, when the drill body 3 is stably placed on the top of the existing pad, the top of the lifting rod 120 is knocked, so that the lifting rod 120 can squeeze the push block 119 and move down quickly.Subsequently, the gap between the pushing block 119 and the pressing block 117 is increased. At this time, it is possible to conveniently separate the connection end inner wall of the pressing block 117 from the drill bit body 3, so as to quickly separate the limiting component from the drill bit body 3, facilitate the connection between the drill pipe body 204 and the drill bit body 3, and improve the replacement efficiency of the actual drill bit body 3.
[0035] During use, the bottom end of the drill mast body 202 is moved to above the drill bit body 3 through the vehicle body 201, and then the winch body 110 is controlled to start releasing the traction rope body, so that the limiting component is inserted into the connection end of the drill bit body 3, enabling the two pressing blocks 117 to be clamped inside the drill bit body 3 through the clamping blocks 118. At this time, the winch body 110 runs in reverse to wind up the traction rope body. Under the support and guidance of the moving guide wheel 114 and the fixed guide wheel 111, the traction rope body can gradually pull the hanging bracket 122 to the vertical state. During this process, the hanging bracket 122 cooperates with the lifting bracket 121 to pull the lifting rod 120 to the outside of the connection end of the drill bit body 3, so that the lifting rod 120 can drive the pushing block 119 to move to the outside of the connection end of the drill bit body 3. Then, the pushing block 119 can squeeze the two pressing blocks 117 during the movement to closely fit the inner wall of the drill bit body 3. When the pushing block 119 cannot move further under the extrusion of the pressing block 117, the continuous traction of the traction rope body enables the hanging bracket 122 to cooperate with the lifting bracket 121, the lifting rod 120, the pushing block 119, the clamping block 118, and the pressing block 117 to gradually pull the connection end of the drill bit body 3 to the vertical state until the drill bit body 3 is completely separated from the ground. At this time, an existing cushion block is placed under the drill bit body 3, and at the same time, by rotating the horizontal angle of the drill bit, the connection direction of the bottom end of the drill pipe body 204 and the connection end of the drill bit body 3 is made consistent. Then, by controlling the winch body 110, the drill bit body 3 can smoothly fall to the top of the existing cushion block in a vertical state. Then, the limiting component is taken out. Furthermore, by maintaining the moving direction of the vehicle body 201, the drill pipe body 204 can be conveniently moved above the connection end of the drill bit body 3, and then the drill pipe can be conveniently connected to the drill bit body 3, enabling the equipment to efficiently replace the drill bit body 3. At the same time, the integrity of the drill pipe body 204 and the drill bit body 3 can be ensured, and damage to the drill pipe body 204 and the drill bit body 3 can be avoided, enabling the equipment to efficiently realize its due functions. At the same time, according to the actual specifications of the drill bit body 3, the positioning bolt 115 is lifted, so that the positioning bolt 115 can be disengaged from the corresponding positioning hole. At this time, under the position limitation of the sliding strip 112, the use position of the limiting frame 113 is moved and adjusted, so that the moving guide wheel 114 can follow the movement. Then, when it is ensured that the drill bit body 3 is not likely to collide with the drill pipe body 204 during suspension, the positioning bolt 115 is released, so that the positioning bolt 115 can be inserted into the current positioning hole through the limiting spring and the retaining ring 116 to fix and limit the position of the limiting frame 113. At the same time, when the drill bit body 3 is stably placed on the top of the existing cushion block, by knocking the top of the lifting rod 120, the lifting rod 120 can be made to squeeze the pushing block 119 to move down quickly, and then the gap between the pushing block 119 and the pressing block 117 is increased. At this time, the pressing block 117 can be conveniently separated from the inner wall of the connection end of the drill bit body 3, so that the limiting component can be quickly separated from the drill bit body 3, facilitating the connection between the drill pipe body 204 and the drill bit body 3 and improving the actual replacement efficiency of the drill bit body 3. At the same time, when the drill bit body 3 is in a suspended state,By controlling and adjusting the use height of the power head body 203, during the movement of the power head body 203, the sliding frame 101 can move in position following the power head body 203 under the support of the pulley 104 and the support wheel 105 through the adjusting bolt 106 and the guiding piece 107. Furthermore, the sliding frame 101 can drive the hanging plate 109 and the sliding bar 112 to move synchronously through the hanging block 102, and then the distance between the suspended drill bit body 3 and the ground can be adjusted. Moreover, the drill bit can be conveniently carried by the vehicle body 201 for position movement, facilitating the synchronous movement and transfer of the replaced drill bit body 3, and at the same time facilitating the placement of the existing cushion blocks, improving the actual use effect of the equipment.
