Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and specifically discloses a device for removing slag from bridge pile foundation drilling. Background Art

[0002] With the rapid development of railways and highways in China, the lengths of railways and highways are gradually increasing, and at the same time, the number of bridges is also increasing. When constructing high-slope bridges, workers need to walk on mountains with relatively large slopes and there is no protection around, which poses a certain threat to the lives of workers. During the construction process, it is first necessary to build the pile foundation of the bridge. First, drilling is required. When drilling, the mud suction method is usually used to clean the soil. During this period, under the action of its own weight, some of the particulate matter suspended in the mud will precipitate at the bottom of the hole. Therefore, before pouring the pile foundation concrete, it is necessary to clean the sediment at the bottom of the hole.

[0003] For example, the invention patent with the patent application number 2017113181174 discloses a drilling cylinder device and a drilling rig, including a drilling cylinder body, a drill pipe, and a sealing member. The drilling cylinder body has a receiving cavity. An opening communicating with the receiving cavity is provided at the bottom of the drilling cylinder body. A positioning member is provided at the bottom of the drilling cylinder body. One end of the drill pipe is connected to the drilling cylinder body, and a drill bit is provided at the other end of the drill pipe. The drill bit extends out of the receiving cavity. The sealing member is rotatably connected to the drill pipe, and a drilling blade is provided on the sealing member. When the existing drilling device drills, although it can timely clean the sediment at the bottom of the hole, the drill bit needs to repeatedly enter the pit foundation. The deeper the pit foundation is, the longer the time consumed by the drill bit moving in the pit foundation. This method requires a lot of time for the drill bit to move, resulting in low efficiency during drilling. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a device for removing slag from bridge pile foundation drilling to solve the technical problem that although the existing drilling device can timely clean the sediment at the bottom of the hole during drilling, the drill bit needs to repeatedly enter the pit foundation, which requires a lot of time for the drill bit to move, resulting in low efficiency during drilling.

[0005] To achieve the above object, the present invention provides the following technical solution: A bridge pile foundation drilling and slag removal device, including a high slope soil body, a pile foundation and a construction platform are arranged on the high slope soil body, the construction platform is located below the pile foundation, a foundation pit is opened on the construction platform, and a reverse circulation drilling machine mechanism is arranged on the construction platform.

The first crushing wheel and the second crushing wheel on the drilling mechanism cooperate with each other to roll the high slope soil body, and with the cooperation of clear water, it is mixed into muddy water, and then the muddy water is moved to a designated position for filtration, so as to achieve the purpose of drilling. When there is a stone in front of the first crushing wheel or the second crushing wheel, it is crushed. If the stone is relatively hard, the first crushing wheel or the second crushing wheel rotates self, preventing the first crushing wheel or the second crushing wheel from being damaged, and the adjacent first crushing wheel or second crushing wheel continues to roll the stone until the stone becomes crushed stone, completing the drilling work.

[0008] Furthermore, the hole cleaning mechanism includes a second fixing block, on which a number of groups of second mating blocks are provided. The number of groups of second mating blocks are clamped in a number of groups of mating grooves, and a number of fastening bolts are inserted through the second fixing block and the mating drill sleeve. Two cleaning components and two collection components are provided on the second fixing block, and the two collection components cooperate with the two cleaning components respectively. By the cooperation of the cleaning component and the collection component, the muddy water in the foundation pit is cleaned, and the drill bit does not need to move repeatedly in the pit, thus improving the efficiency of hole cleaning and drilling.

[0009] Furthermore, the cleaning component includes a flipping box, which is slidably clamped on the second fixing block. A second feeding groove and a second inclined groove are formed on the second fixing block, and the second feeding groove is communicated with the second inclined groove. A gravity sensor is arranged inside the second fixing block and contacts with the flipping box. A fixing shaft is arranged on the flipping box, and the fixing shaft is rotatably connected to the inside of the second fixing block, and a rotating device is arranged at one end of the fixing shaft. The cleaning component can collect the muddy water entering the mating drill sleeve into the flipping box. When the muddy water in the flipping box reaches a certain mass, the flipping box moves the muddy water into the collection component to collect the muddy water.

[0010] Furthermore, the collection component includes a first collection box, which is clamped on the second fixing block.

The limiting frame is inserted through the limiting block, and the upper end of the limiting frame is arc-shaped and the lower end is linear. A second collection box is arranged on the second fixing block. The collection component moves the muddy water in the flipping box into the first collection box, and then controls the movement of the first collection box to move the muddy water into the second collection box.

[0011] Furthermore, the support mechanism includes a fixed seat, on which a number of ground plugs are provided. The number of ground plugs are inserted into the high slope soil body. A first mating frame is hinged on the fixed seat, and a fixing block is clamped between the fixed seat and the first mating frame.

[0012] Furthermore, a passageway mechanism is provided on the support mechanism. One end of the passageway mechanism is connected to the support mechanism, and the other end is connected to the pile foundation. The passageway mechanism includes a number of cooperating components arranged in a linear array; each cooperating component includes a bottom plate, with hinge seats provided on both sides of the bottom plate. The two hinge seats are staggered vertically, and guardrails are hinged on both hinge seats; the second cooperating frame is hinged to one of the bottom plates. Workers can walk on the passageway mechanism, thus ensuring the safety of the workers' lives. Workers do not need to move on the high-slope soil mass.

[0013] Furthermore, a first fixing groove is provided at the center of one of the bottom plates, and a baffle is clamped in the first fixing groove; a clamping block is fixedly connected in the first fixing groove, and the clamping block is clamped in the first fixing groove. A ladder is fixedly connected to the bottom plate. Workers can move from the passageway mechanism to the construction platform through the ladder.

When building the support mechanism and the passageway mechanism, by telescoping the hydraulic cylinder, the length of the support mechanism is controlled, and at the same time, the angle of the support mechanism is adjusted, so as to ensure that the passageway mechanism is always horizontal during assembly, facilitating the installation of the support mechanism and the passageway mechanism by workers. When the support mechanism and the passageway mechanism are installed, the workers remove the baffle and fix the ladder on the corresponding bottom plate. The workers clamp the two fixing blocks between the first cooperating frame and the fixed seat to ensure that the first cooperating frame does not rotate around the fixed seat. At this time, when the workers pass through the passageway mechanism and the support mechanism, they do not need to climb on the high-slope soil mass, thus ensuring the safety of the workers when walking.

[0015] During drilling, workers first install the drilling mechanism on the reverse circulation drilling rig mechanism, and drill the high-slope soil mass through the reverse circulation drilling rig mechanism to drill out the foundation pit. When it is necessary to clean the hole, the drilling mechanism is disassembled, and the hole cleaning mechanism is installed on the reverse circulation drilling rig mechanism to clean the foundation pit. During hole cleaning, the cleaning mechanism only needs to enter the foundation pit once to complete the hole cleaning work of the foundation pit, reducing the hole cleaning time, thereby improving the hole cleaning efficiency.

When the gravity sensor 516 reaches the threshold, the central control element controls the rotating device 508 to start. After a period of time, the rotating device 508 returns to its initial state. At this time, the central control element simultaneously controls the second lifting device to start.

[0025] During specific implementation: During use, the staff first inserts the fixing block 215 into the ground and fixes the fixing seat 201 on the high slope soil body 101. At this time, the hydraulic cylinder 204 is parallel to the inclined surface of the high slope soil body 101. Then, the staff adjusts the hydraulic cylinder 204, and the hydraulic cylinder 204 drives the second fitting frame 205 to move. The second fitting frame 205 slides in the fixing groove 203 until the other end of the second fitting frame 205 moves to the pile foundation 102. Then, the staff connects the fitting components. Then, the staff moves the fitting components so that one end of the fitting components is separated from the pile foundation 102, and the other end is located on one side of the pile foundation 102. At this time, the fitting components drive the second fitting frame 205, the hydraulic cylinder 204, and the first fitting frame 202 to move, causing the first fitting frame 202 to rotate around the fixing seat 201. At the same time, the second fitting frame 205 rotates around the corresponding fitting components. Then, the staff fixes another set of fitting components to the corresponding fitting components, and so on, to build the aisle mechanism, and at the same time drives the first fitting frame 202 and the second fitting frame 205 to rotate until the first fitting frame 202 and the second fitting frame 205 are vertical. Then, the fixing block 215 is clamped between the first fitting frame 202 and the fixing seat 201. At this time, the first fitting frame 202 is fixedly connected to the fixing seat 201, and the aisle mechanism is built. When the first fitting frame 202 and the second fitting frame 205 rotate around the fixing seat 201, the staff contracts the hydraulic cylinder 204 to ensure that the fitting components always remain horizontal, thus facilitating the staff to install the fitting components; the support mechanism and the aisle mechanism can facilitate the staff to move to the construction platform 103, and at the same time ensure the safety of the staff, and can effectively prevent the situation where the staff is injured while moving on the high slope soil body 101.

[0026] After the staff have completed the installation of the support mechanism and the aisle mechanism, the staff then take out the baffle 209 from the corresponding bottom plate 206. At this time, the first fixing groove 210 is exposed. Then the staff fix the aerial ladder 213 on the corresponding bottom plate 206. The staff move onto the high slope soil mass 101 through the aerial ladder 213. Then the staff pour a construction platform 103 at the designated position. At this time, a foundation pit 104 is formed on the construction platform 103. Then the staff install the reverse circulation drilling rig mechanism on the construction platform 103. The staff first install the drilling mechanism on the reverse circulation drilling rig mechanism to drill the high slope soil mass 101. Then the drilling mechanism is disassembled. Then the hole cleaning mechanism is installed on the reverse circulation drilling rig mechanism. The staff clean the foundation pit 104 through the hole cleaning mechanism. During hole cleaning, the staff do not need to enter the construction platform 103 to complete the hole cleaning, which can ensure the safety of the staff.

[0027] When building the aisle mechanism, the initial state of the matching components is that one set of guardrails 208 is located above the bottom plate 206, and the other set of guardrails 208 is located below the bottom plate 206. The bottom plate 206 is in contact with the two sets of guardrails 208. The two sets of guardrails 208 and the bottom plate 206 can form a rectangle, thus reducing the space of the matching components and facilitating the staff to move the matching components. When installing the matching components, the staff rotate the two sets of guardrails 208 around the hinge seat 207 so that the two sets of guardrails 208 and the bottom plate 206 form a U shape. Then the staff fix the guardrails 208 on the bottom plate 206. Then the staff fix two adjacent matching components with bolts, so that the bottom plate 206 is fixed to the adjacent bottom plate 206, and the guardrails 208 are fixed to the corresponding guardrails 208.

[0028] When the staff installs the drilling mechanism, first align Ruoganu with the first fitting block 402 and several groups of fitting grooves 306, then snap the first fitting block 402 into the corresponding fitting groove 306, and then fix the fitting drill sleeve 305 and the first fixing block 401 with the fastening bolt 307; when the drilling mechanism drills, the staff starts the first lifting device 301 and the slewing device 303. The slewing device 303 drives the drill rod 304 and the fitting drill sleeve 305 to rotate. The fitting drill sleeve 305 drives the drilling mechanism to rotate. The first lifting device 301 drives the first moving block 302 to move downward. The first moving block 302 drives the slewing device 303, the drill rod 304, the fitting drill sleeve 305 and the drilling mechanism to move downward. Drill the high-slope soil body 101 through the drilling mechanism. When the drilling mechanism rotates, the fitting drill sleeve 305 drives the first fixing block 401 to rotate. The first fixing block 401 drives the first crushing wheel 409 and the second crushing wheel 410 to rotate. When the first crushing wheel 409 and the first fixing block 401 rotate, they roll over the high-slope soil body 101. At the same time, the first fixing block 401 descends, squeezing the soil with the first crushing wheel 409 and the second crushing wheel 410 to separate it from the high-slope soil body 101. While drilling, the staff injects clear water into the foundation pit 104 at the same time. The clear water mixes with the soil to form muddy water. The muddy water moves through the first feed trough 407 into the fitting drill sleeve 305, then enters the drill rod 304, and finally flows to the filter tank. When a stone appears in front of the drilling mechanism, the first crushing wheel 409 or the second crushing wheel 410 crushes the stone into gravel, which enters the fitting drill sleeve 305 through the first inclined trough 404 and finally flows out of the drill rod 304 together with the muddy water. When the first fixing block 401 moves downward, the tapered block 408 pushes the soil around. Several groups of second crushing wheels 410 cooperate with each other to move the soil and gravel toward the center of the first fixing block 401, and finally move from the first feed trough 407 into the fitting drill sleeve 305. Several groups of stirring rods 405 stir the muddy water in the fitting drill sleeve 305 to make the muddy water in the fitting drill sleeve 305 mix evenly, preventing the soil content below the fitting drill sleeve 305 from being higher than that above the fitting drill sleeve 305, resulting in more residual soil in the subsequent foundation pit 104 and being inconvenient for subsequent cleaning.

[0029] When the staff performs the cleaning, the staff first removes the fastening bolt 307, then separates the first fixing block 401 from the mating drill sleeve 305, separates the drilling mechanism from the mating drill sleeve 305, and then the staff aligns the second mating block 502 with the mating groove 306 so that the second mating block 502 is clamped in the mating groove 306. Then the staff fixes the mating drill sleeve 305 and the second fixing block 501 through the fastening bolt 307. At this time, the hole cleaning mechanism is installed on the mating drill sleeve 305. Then the staff first cooperates with the first lifting device 301 and the first moving block 302 to move the hole cleaning mechanism to the bottom of the foundation pit 104, and then starts the rotating device 303. The rotating device 303 drives the drill rod 304, the mating drill sleeve 305 and the hole cleaning mechanism to rotate. When the second fixing block 501 rotates, the muddy water at the bottom of the foundation pit 104 moves to the turnover box 506 through the second feeding groove 503 and the second inclined groove 504. When the muddy water contained in the turnover box 506 reaches the threshold value of the gravity sensor 516, the gravity sensor 516 will be triggered. At this time, the gravity sensor 516 transmits the signal to the central control element, and the central control element controls the rotating device 508 to start. The output end of the rotating device 508 drives the fixed shaft 507 to rotate, and the fixed shaft 507 drives the turnover box 506 to rotate, so that the turnover box 506 rotates 90 degrees. At this time, the turnover box 506 is perpendicular to the first collection box 509, and the muddy water flows from the turnover box 506 into the fixed shaft 507. After a period of time, the rotating device 508 starts again to drive the turnover box 506 to return to the initial state. At the same time, the second lifting device 510 starts, and the second lifting device 510 drives the second moving block 511 to rise. The second moving block 511 drives the first collection box 509 to rise, and the first collection box 509 drives the limiting block 513 to slide on the limiting frame 514. When the limiting block 513 slides to the junction of the straight section and the arc section of the limiting frame 514, the second moving block 511 stops moving. The rotating device 508 starts, and the output end of the rotating device 508 drives the first collection box 509 to rotate. The first collection box 509 drives the limiting block 513 to move on the arc section of the limiting frame 514. At this time, the first collection box 509 turns over, and the muddy water in the first collection box 509 is poured into the second collection box 515 to collect the muddy water; the hole cleaning mechanism can remove the muddy water at the bottom of the foundation pit 104, and at the same time can ensure the cleaning effect. And the hole cleaning mechanism only needs to enter the foundation pit 104 once to complete the hole cleaning work of the foundation pit 104, saving a lot of time, thereby improving the hole cleaning efficiency.

[0030] The above are only the embodiments of the present invention. Common knowledge such as the specific structures and characteristics in the solutions is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the present invention.
