Description

Technical Field

[0002] During the construction of bridge foundation, it is necessary to use a rotary drilling rig to pre-position and drill holes before driving the pile foundation. Due to the complex structure of the soil layer, relatively hard parts such as stones are often encountered during the drilling process. The drill bit of the existing rotary drilling rig will continue to move forward after encountering hard stones, and the torque borne by the drill bit will increase, which is easy to cause damage to the drill bit. At the same time, when the drill bit rotates the soil into the cavity of the rotary drilling rig, the soil is easy to adhere to the inner wall of the accommodating cavity of the drill tool, making it difficult to fully unload the soil, thereby reducing the space inside the drill tool, indirectly leading to an increase in the frequency of unloading soil and a decrease in work efficiency.

[0036] like Figures 1 to 12 As shown, an embodiment of the present invention provides a municipal road bridge drilling and punching equipment, including a receiving tube 100 and a drill bit mechanism, the receiving tube 100 is vertically arranged, and the receiving tube 100 can rotate around its own axis relative to the ground, and the interior of the receiving tube 100 is provided with a first cavity 101 that can accommodate materials; the drill bit mechanism includes a mounting tube 102, an excavation assembly and an auxiliary drive assembly, a column 103 is provided at the bottom of the mounting tube 102, and the column 103 is coaxial with the receiving tube 100; a support plate 104 is provided at the bottom of the receiving tube 100, and the support plate 104 is located directly below the wall of the receiving tube 100, the mounting tube 102 is arranged at the bottom of the receiving tube 100, and the two ends of the mounting tube 102 are respectively connected to the support plate 104 and the column 103, and the mounting tube 102 extends along the radial direction of the receiving tube 100.

[0037] The excavating assembly is sleeved on the mounting cylinder 102, and the excavating assembly has a first state and a second state. In the first state, the excavating assembly is stationary relative to the mounting cylinder 102, and a feed port 125 is provided at the bottom of the containing cylinder 100. When the containing cylinder 100 rotates, the excavating assembly can transport the soil under the mounting cylinder 102 and in contact with the excavating assembly into the first cavity 101; in the second state, the excavating assembly rotates around the mounting cylinder 102, and no longer transports the soil in contact with the excavating assembly into the first cavity 101.

[0038] During use, the excavating assembly is in a first state. After the resistance of the obstacle encountered by the excavating assembly to the excavating assembly reaches a preset value, the excavating assembly can be transformed from the first state to the second state.

[0039] The auxiliary driving assembly provides a continuous rotation force for the excavating assembly when the excavating assembly is in the second state, and causes the excavating assembly to change from the second state to the first state.

[0040] When the excavating component is drilling in the first state, the excavated soil is guided into the accommodating tube 100, and the municipal road and bridge drilling and perforating equipment can continue to perform the drilling work. Through the matching arrangement of the excavating component and the mounting tube 102, when the excavating component encounters a hard obstacle such as a stone, as the accommodating tube 100 rotates, the resistance between the excavating component and the stone increases to a preset value, and then the excavating component in contact with the stone stops drilling and rotates relative to the mounting tube 102, and changes from the first state to the second state. After the excavating component rotates, the mounting tube 102 corresponding to the excavating component will pass over the stone, and the excavating component will slide over the stone, thereby avoiding the excavating component and the stone. In order to prevent the damage of the excavation assembly caused by the increasing resistance, an auxiliary driving assembly is provided. After the excavation assembly changes from the first state to the second state, the excavation assembly is driven to continuously rotate around the mounting tube 102, so that the excavation assembly rotates around the mounting tube 102 and can go around the rear of the stone, and changes from the second state to the first state, and continues to excavate the subsequent soil layers. At the same time, when the excavation assembly rotates to the rear of the stone, it impacts the stone, which helps to loosen the stone quickly. At the same time, due to the continuous drilling of the municipal road and bridge drilling and punching equipment, the excavation assembly can loosen part of the soil around the stone each time, accelerate the loosening of the stone, and the stone will be guided into the first cavity 101 by the excavation assembly after it is no longer wrapped by the soil.

[0041] In this embodiment, the excavation assembly includes a transmission ring 105, a rotating ring 106 and an excavation plate 107. The transmission ring 105 is sleeved on the mounting tube 102, and the transmission ring 105 can rotate relative to the mounting tube 102. A first slide groove 108 is provided on the circumferential surface of the transmission ring 105. The projection of the first slide groove 108 in the axial direction of the transmission ring 105 is an ellipse, and the center of the ellipse is located on the axis of the transmission ring 105. The rotating ring 106 is sleeved on the transmission ring 105, and the rotating ring 106 can rotate relative to the mounting tube 102. Able to rotate relative to the transmission ring 105; a spacing is provided between the mounting cylinder 102 and the bottom wall of the accommodating cylinder 100, two digging plates 107 are provided, the two digging plates 107 penetrate the rotating ring 106 along the radial direction of the rotating ring 106, the digging plates 107 are slidingly connected with the rotating ring 106 along the radial direction of the rotating ring 106, the sliding directions of the two digging plates 107 on the rotating ring 106 are parallel, and one end of each digging plate 107 penetrates the rotating ring 106 and is slidably arranged in the first slide groove 108.

[0042] When the excavation assembly is in the first state, the angle between the major axis of the ellipse and the horizontal plane is the angle at which the excavation plate 107 drills into the soil layer. At this time, the length extension direction of the two excavation plates 107 is consistent with the extension direction of the major axis of the ellipse, and one of the excavation plates 107 is located below the mounting cylinder 102 and is responsible for drilling the soil, and the other excavation plate 107 is located above the mounting cylinder 102. The end of the excavation plate 107 located above the mounting cylinder 102 away from the mounting cylinder 102 is close to the feed port 125, and the soil drilled by the excavation plate 107 located below the mounting cylinder 102 can be passed through the feed port 125. Guided into the first cavity 101; when the excavating plate 107 abuts against the stone in the soil layer, the accommodating tube 100 continues to rotate, and the resistance of the stone to the excavating plate 107 continues to increase. After the resistance reaches a preset value, the rotating ring 106 drives the excavating plate 107 to rotate relative to the transmission ring 105, and the position where the excavating plate 107 abuts against the stone remains unchanged. The end of the excavating plate 107 away from the stone slides in the first slide groove 108 and approaches the short axis position of the ellipse from the long axis position of the ellipse. The excavating plate 107 shrinks into the rotating ring 106, thereby no longer increasing the pressure on the excavating plate 107.

[0043] In this embodiment, a plurality of mounting cylinders 102 are provided, and the plurality of mounting cylinders 102 are evenly distributed around the circumference of the column 103, and a plurality of excavation components are provided on each mounting cylinder 102, and the plurality of excavation components are arranged along the axial direction of the mounting cylinder 102. The provision of the plurality of excavation components is beneficial to improving the working efficiency of the municipal road and bridge drilling and punching equipment.

[0044] In this embodiment, the auxiliary drive assembly includes an energy storage unit and a drive unit. The energy storage unit includes a positioning plate 109, a torsion spring 110 and a trigger. A plurality of positioning plates 109 are provided. The plurality of positioning plates 109 are fixedly mounted on the mounting tube 102, and the plurality of positioning plates 109 are evenly arranged on the mounting tube 102 along the length direction of the mounting tube 102. A transmission ring 105 is provided between two adjacent mounting tubes 102, and the positioning plate 109 is slidably connected to the transmission ring 105. A plurality of torsion springs 110 are provided, and each torsion spring 110 A corresponding portion is provided between a transmission ring 105 and a rotating ring 106 in an excavation assembly. A receiving groove 111 is provided on a surface of the rotating ring 106 that contacts the transmission ring 105. A torsion spring 110 is sleeved on the transmission ring 105. The torsion spring 110 is located in the receiving groove 111. Both ends of the torsion spring 110 are respectively connected to the corresponding transmission ring 105 and the rotating ring 106. When the transmission ring 105 rotates relative to the rotating ring 106, the torsion spring 110 can store force. A trigger member is provided on the positioning plate 109 and the transmission ring 105. The trigger is used to control whether relative rotation occurs between the transmission ring 105 and the mounting tube 102 according to the amount of force stored in the torsion spring 110; the driving unit is used to drive the rotating transmission ring 105 to continue to rotate. After the excavation plate 107 encounters a stone, the resistance of the excavation plate 107 increases, and the excavation plate 107 drives the rotating ring 106 to rotate relative to the transmission ring 105. Under the action of the trigger, relative rotation does not occur between the transmission ring 105 and the mounting tube 102. At this time, the torsion spring 110 starts to store force. When the torsion spring 110 starts to store force, the torsion spring 110 starts to store force. After a certain force is accumulated, the trigger member controls the transmission ring 105 to rotate relative to the mounting tube 102. The transmission ring 105 rotates relative to the mounting tube 102 under the action of the torsion spring 110. When the accumulated force of the torsion spring 110 is released, the transmission ring 105 continues to rotate under the action of the driving part, and drives the digging plate 107 to rotate around the mounting tube 102, so that the digging plate 107 in contact with the stone is out of contact with the stone, and the other digging plate 107 is in contact with the soil layer on the other side of the stone, and the drilling work continues.

[0045] In this embodiment, the trigger member includes a threaded rod 112, a push plate 113, a block 114 and a first spring 115. The threaded rod 112 is rotatably arranged on the transmission ring 105, and the axis of the threaded rod 112 is parallel to the axis of the transmission ring 105. The threaded rod 112 is slidably connected to the rotating ring 106. The end surface of the transmission ring 105 is provided with a step, and the step includes a first end surface 116 and a second end surface 117. The first end surface 116 contacts the corresponding positioning plate 109, and the second end surface 117 contacts the rotating ring 106. The rotating ring 106 contacts the second end surface 117. A first groove 118 is provided on the contact side, and the first groove 118 is an annular groove, and the first groove 118 is coaxial with the rotating ring 106. The end of the threaded rod 112 away from the transmission ring 105 is arranged in the first groove 118. The threaded rod 112 is rotatably connected with the rotating ring 106, and there is a large friction force between the threaded rod 112 and the rotating ring 106. When the rotating ring 106 rotates relative to the transmission ring 105, the rotating ring 106 can drive the threaded rod 112 to rotate around its own axis, and the push plate 113 is slidably arranged on the transmission ring 105 along the axial direction of the transmission ring 105. 05, and the push plate 113 is threadedly connected with the threaded rod 112, a second groove 119 is provided on the side of the transmission ring 105 close to the positioning plate 109, the push plate 113 is slidably arranged in the second groove 119, the clamping block 114 is slidably arranged on the transmission ring 105 along the axial direction of the transmission ring 105, the clamping block 114 is slidably arranged in the second groove 119, a clamping groove 120 is provided on the positioning plate 109, the clamping block 114 is located on the side of the push plate 113 close to the clamping groove 120, and the clamping block 114 slides along the axial direction of the rotating ring 106 and can pass through the clamping groove 120 The first spring 115 is connected with the positioning plate 109, and the first spring 115 is arranged between the push plate 113 and the block 114, and the two ends of the first spring 115 are respectively connected with the push plate 113 and the block 114. The rotation of the threaded rod 112 will drive the push plate 113 to move along the axial direction of the threaded rod 112. The push plate 113 generates a gradually increasing pulling force on the block 114 by stretching the first spring 115, so that the block 114 can quickly move away from the slot 120, avoiding the contact area between the block 114 and the positioning plate 109 gradually decreasing and the block 114 itself being damaged by excessive local pressure.

[0046] In this embodiment, the driving unit includes a first motor 121, a transmission shaft 122 and a plurality of magnet groups. The first motor 121 is arranged in the column 103.

When the first magnet 123 and the second magnet 124 are close to each other, they attract each other, and the multiple magnet groups are evenly distributed along the axial direction of the transmission shaft 122. Suction is generated between the first magnet 123 and the second magnet 124. After the first motor 121 drives the transmission shaft 122 to rotate, the first magnet 123 on the transmission shaft 122 drives the transmission ring 105 to rotate through magnetic force. When the transmission ring 105 can rotate relative to the mounting tube 102, the first spring 115 provides the transmission ring 105 with rotation power. The rotated transmission ring 105 can continue to rotate under the action of the first magnet 123 and the second magnet 124, so that the other excavation plate 107 is in contact with the soil layer.

The output shaft of the second motor 205 is coaxial with the accommodating cylinder 100.

[0048] In this embodiment, each connecting plate 202 is provided with an adjustment assembly, each adjustment assembly includes a rotating disk 207, a gear 208, a rack plate 209 and a second spring 210, the rotating disk 207 is sleeved in the rotating drum 201, and the rotating disk 207 is rotatably connected to the rotating drum 201, and the output shaft of the second motor 205 is fixedly connected to the rotating disk 207, and the second motor 205 can drive the rotating disk 207 to rotate in the rotating drum 201. Figure 7As shown, a plurality of third grooves 211 are provided on the circumference of the rotating disk 207, a second slide groove 212 is provided inside the connecting plate 202, the number of gears 208 is consistent with the number of the dial plates 203, and the plurality of gears 208 are rotatably arranged in the second slide groove 212, each gear 208 is correspondingly connected to the rotating shaft of a dial plate 203, a rack plate 209 is slidably arranged in the second slide groove 212 along the length extension direction of the connecting plate 202, and the rack plate 209 is meshed with the plurality of gears 208, an end of the rack plate 209 close to the rotating drum 201 passes through the connecting plate 202 and the rotating drum 201 and is slidably arranged in the third groove 211, the rack plate 209 is slidably connected to the rotating drum 201, and the second elastic The spring 210 is arranged in the second slide groove 212, and the second spring 210 is extended and retracted along the sliding direction of the rack plate 209 in the second slide groove 212, and the two ends of the second spring 210 are respectively abutted against the connecting plate 202 and the end of the rack plate 209 away from the third groove 211, and the second spring 210 is always in a compressed state, the end of the rack plate 209 is always abutted against one side of the third groove 211, and the side where the third groove 211 abuts against the end of the rack plate 209 is an inclined surface, and the side where the gear 208 is meshed with the rack plate 209 is the first side, and the side of the gear 208 away from the first side is the second side, and the inclined surface gradually moves away from the connecting plate 202 in the direction from the first side to the second side.

In this way, as the soil in the first cavity 101 increases, the soil and stones move upward as a whole, and the stones in the soil contact the inner wall of the accommodating tube 100, reducing the contact area between the soil and the inner wall of the accommodating tube 100, thereby facilitating the discharge of the soil in the first cavity 101.

[0050] In another embodiment, each adjustment component includes a control panel and multiple micro motors, and an installation cavity is provided inside each connecting plate 202.

[0051] In this embodiment, one end of the column 103 located below the accommodating tube 100 is tapered, so that the municipal road and bridge drilling and perforating equipment can push the soil that is not easily accessible by the excavation plate 107 to the vicinity of the excavation plate 107 when drilling in the soil layer.

[0052] In this embodiment, a side door plate 213 is rotatably provided on the circumference of the accommodating cylinder 100, and the rotation axis of the side door plate 213 is parallel to the axis of the accommodating cylinder 100. A third motor 214 is fixedly installed on the accommodating cylinder 100, and the output shaft of the third motor 214 is fixedly connected to the side door plate 213, and the axis of the output shaft of the third motor 214 coincides with the rotation axis of the side door plate 213. The side door plate 213 is located on the side of the bottom plate away from the drill bit mechanism, and the distance between the side door plate 213 and the bottom plate is as short as possible. After a certain amount of soil is contained in the accommodating cylinder 100, the third motor 214 is started, and the third motor 214 can drive the side door plate 213 to rotate, so that the soil in the accommodating cylinder 100 can be discharged from the accommodating cylinder 100.

[0053] The working principle and working method of a municipal road bridge drilling and punching device provided in this embodiment are as follows:

[0054] First, the accommodating cylinder 100 is driven to rotate by an external driving device, and the accommodating cylinder 100 drives the drill mechanism and the conveying mechanism to rotate. As the accommodating cylinder 100 continues to move downward, the excavating plate 107 finally contacts the soil layer. The excavating plate 107 in contact with the soil layer shovels up the soil and approaches the feed port 125 under the guidance of the excavating plate 107. After the excavating plate 107 continuously conveys the shoveled soil, the soil will enter the first cavity 101.

[0055] When the accommodating cylinder 100 rotates, the first motor 121 and the second motor 205 are started. The first motor 121 drives the multiple transmission shafts 122 to rotate in the corresponding mounting cylinder 102. At this time, the transmission shaft 122 cannot drive the transmission ring 105 to rotate around the mounting cylinder 102 through the cooperation of the first magnet 123 and the second magnet 124; the second motor 205 reciprocates and drives the turntable 207 to reciprocate. When the turntable 207 rotates, the rack plate 209 slides in the third groove 211. When the rack plate 209 abuts against the turntable 207, the turntable 207 drives the connecting plate 202 and the rotating cylinder 201 to rotate through the rack plate 209. When the plate 209 slides in the third groove 211, the rack plate 209 slides in the second slide groove 212 along the length direction of the second slide groove 212 through the action of the inclined surface of the third groove 211 and the second spring 210, and the rack plate 209 drives the dial plate 203 to rotate through the gear 208. In the direction of rotation of the rotating cylinder 201, the end of the dial plate 203 close to the turntable 207 is located in front of the end of the dial plate 203 close to the inner wall of the accommodating cylinder 100. The vertical rod 204 on the dial plate 203 guides the stones in the soil entering the first cavity 101 to approach the inner wall of the accommodating cylinder 100, and the soil passes through between the two adjacent vertical rods 204 on the dial plate 203.

[0056] When the digging plate 107 shovels a larger stone, the accommodating cylinder 100 continues to rotate. After the resistance encountered by the digging plate 107 is greater than the resistance provided by the torsion spring 110 to the rotating ring 106, the digging plate 107 begins to drive the rotating ring 106 to rotate around the transmission ring 105. When the digging plate 107 rotates, through the cooperation with the first slide groove 108 on the transmission ring 105, the digging plate 107 contracts inward relative to the rotating ring 106 along the radial direction of the rotating ring 106; while the rotating ring 106 rotates relative to the transmission ring 105, the torsion spring 110 begins to accumulate force, and the rotating ring 106 drives the threaded rod 112 to rotate around its own axis through friction force. The rotation of the threaded rod 112 drives the push plate 113 to move in the direction away from the block 114, and the push plate 113 and the block 114 are moved. 4 is stretched, and the block 114 is subjected to a pulling force approaching the push plate 113; as the rotating ring 106 rotates relative to the transmission ring 105, the pulling force of the first spring 115 on the block 114 becomes greater and greater, and finally the block 114 is pulled out of the slot 120, and the transmission ring 105 and the positioning plate 109 can rotate relative to each other, and then the torsion spring 110 starts to release energy, and the transmission ring 105 rotates relative to the rotating ring 106 under the action of the torsion spring 110, and the threaded rod 112 starts to reverse, and the push plate 113 pushes the block 114 to slide in the second groove 119 through the first spring 115. When the torsion spring 110 has released all its energy, the block 114 abuts against the positioning plate 109, and the first spring 115 is compressed by the push plate 113 and the block 114.

[0057] During the energy release process of the torsion spring 110, the transmission ring 105 rotates relative to the installation cylinder 102, and the second magnet 124 rotates around the installation cylinder 102. At this time, the transmission shaft 122 is always in the rotation process. The transmission shaft 122 drives the transmission ring 105 to rotate continuously through the suction force of the first magnet 123 and the second magnet 124. The transmission ring 105 drives the rotating ring 106 to rotate through the torsion spring 110, and the rotating ring 106 drives the two excavation plates 107 to rotate. The excavation plates 107 that were originally in contact with the stone move closer to the feed port 125. The excavating plate 107 of the material port 125 approaches the soil layer. When the excavating plate 107 approaches the soil layer, it will pass over the stone and contact the soil layer. As the accommodating tube 100 rotates, the excavating plate 107 that has just contacted the soil layer is inserted into a part of the soil layer. At the same time, the transmission ring 105 continues to rotate, and the block 114 moves to a position that cooperates with the slot 120. Under the action of the first spring 115, the block 114 slides into the slot 120, and the transmission ring 105 no longer rotates relative to the mounting tube 102. The excavating plate 107 can continue to shovel the soil to complete the drilling work.

[0058] As the above actions are repeated, the soil around the stones in the soil layer is shoveled away, the stones become loose, and are finally guided into the first cavity 101.

[0059] When the soil in the first cavity 101 is loaded, the accommodating tube 100 is pulled out of the drill hole, and then the accommodating tube 100 is moved to the unloading position, and the third motor 214 is started. The third motor 214 drives the side door panel 213 to rotate, and the soil in the first cavity 101 is discharged. Since the stones in the soil are basically on the inner wall of the accommodating tube 100, the amount of soil in the first cavity 101 sticking to the inner wall of the accommodating tube 100 is greatly reduced.

[0060] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
