Description

Technical Field

[0001] The invention belongs to the technical field of pile barrel hoisting, in particular to a bored cast-in-place pile construction device and a construction method. Background Art

[0002] In the field of modern bridge construction, the construction of water bridges is an important and complex project. With the continuous advancement of transportation infrastructure construction, more and more water bridge projects are being carried out in major rivers, lakes and coastal areas. The pile foundation is the key supporting structure of the water bridge, and its construction quality directly affects the stability and safety of the bridge. In the hoisting operation of the pile barrel of the water bridge, the traction cable plays an indispensable role.

[0003] The traction cable is responsible for accurately lifting the pile barrel to the designated location. Its performance is directly related to the accuracy and efficiency of the pile barrel lifting. However, the construction environment of the water bridge is uniquely complex, among which high humidity is a significant feature: the construction area is affected by water evaporation, rainfall and humid air for a long time, and the humidity is often maintained at a high level all year round; in such an environment, the traction cable is very susceptible to corrosion. The cable is usually made of metal. The moisture in the high humidity environment will react chemically with oxygen, carbon dioxide and other components in the air to form a layer of electrolyte solution on the surface of the cable, thereby causing electrochemical corrosion. Corrosion will not only reduce the strength and toughness of the cable, but also reduce its service life, seriously threatening the safety of the pile barrel lifting operation.

[0004] In order to deal with this problem, the current conventional practice is to use a coating maintenance method to protect the traction cable. However, this traditional method has many inconveniences. In actual operation, the application of curing agent requires construction workers to work at high altitude or on a narrow working platform. The coating process requires a lot of manpower and time. In the construction of water bridges with tight schedules, this will undoubtedly increase the construction cost and time cost. In addition, in the subsequent use of the cable, due to frequent stretching, bending and other actions, the applied curing agent is easy to fall off and needs to be repeatedly applied, which further increases the difficulty and workload of maintenance.

[0057] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0058] like Figures 1 to 13 As shown, a bored pile construction device described in the present invention includes a lifting part, a driving mechanism, a diversion mechanism, a coating mechanism and a cleaning mechanism.

[0059] The lifting part includes a mounting frame 1, a connecting hook 4 and a traction cable 3. The mounting frame 1 is used to be connected to the tower crane. The mounting frame 1 is connected to the movable end of the tower crane through bolts.

[0060] The connecting hook 4 is arranged below the mounting frame 1 , and the lifting and lowering of the connecting hook 4 is controlled by the traction steel cable 3 . The connecting hook 4 is used to be connected to the internal support type pile turning device.

[0061] The driving mechanism is used for winding and unwinding the traction steel cable 3. After the internal support pile turner is connected to the pile barrel, the connecting hook 4 is controlled to rise by winding the traction steel cable 3, thereby driving the pile barrel to rise. Then, the pile barrel is controlled to move to the target position by moving the swing arm of the tower crane. Then, the traction steel cable 3 is unwound to control the pile barrel to descend to the required position. Finally, the internal support pile turner is controlled to separate from the pile barrel, thereby completing the hoisting and laying of the pile barrel of the cast-in-place pile construction.

[0062] The smearing mechanism comprises a mounting frame 12 and a smearing strip 13. The mounting frame 12 is fixedly mounted on the inner wall of the mounting frame 1, and the mounting frame 12 is a "U"-shaped structure.

[0063] The smear strip 13 is fixedly mounted on the inner wall of the mounting frame 12 , and the smear strip 13 is made of a common sponge material so as to absorb the maintenance liquid of the steel cable.

[0064] The traction steel cable 3 passes through the installation frame 12, and the outer wall of the traction steel cable 3 fits with the outer wall of the coating strip 13. During the process of winding and unwinding the traction steel cable 3, the traction steel cable 3 rubs against the coating strip 13, so that the curing liquid absorbed by the coating strip 13 is evenly smeared on the outer wall of the traction steel cable 3. At the same time, the dust on the outside of the traction steel cable 3 is preliminarily wiped off, thereby realizing the maintenance of the traction steel cable 3, maintaining the strength of the traction steel cable 3, and improving the service life.

[0065] The guide mechanism is used to introduce the curing liquid into the smear strip 13, so as to keep the smear strip 13 moist. When the smear strip 13 is moist, it generates friction with the traction cable 3, which can extend the service life of the smear strip 13 as much as possible.

[0066] The cleaning mechanism includes a cleaning roller 10 and a support plate 22. The support plate 22 is arranged in the mounting frame 1 and is used to support the cleaning roller 10. The cleaning roller 10 is made of elastic material and is supported by the support plate 22. During the process of winding the traction steel cable 3, the cleaning roller 10 is kept in contact with the traction steel cable 3, thereby wiping impurities on the outer wall of the traction steel cable 3 and absorbing excess maintenance liquid on the outer wall of the traction steel cable 3.

[0067] The driving mechanism includes a driving motor 6 , a mounting box 5 , a control worm gear 30 , a control worm 31 and a winding roller 15 .

[0068] The installation box 5 is fixedly installed on the outer wall of the installation frame 1, and the winding roller 15 is rotatably arranged on the inner wall of the installation frame 1, wherein one end of the traction steel cable 3 is connected to the winding roller 15, and when the winding roller 15 is rotated, the winding and unwinding of the traction steel cable 3 is realized.

[0069] The control worm gear 30 is rotatably mounted on the inner wall of the mounting box 5, and the axial end of the control worm gear 30 is fixedly connected to the center position of the axial end of the winding roller 15. The mounting box 5 provides an installation space for the control worm gear 30. Rotating the control worm gear 30 drives the winding roller 15 to rotate.

[0070] The control worm 31 is rotatably mounted on the inner wall of the mounting box 5 and meshes with the control worm wheel 30 . The rotation of the control worm 31 drives the control worm wheel 30 to rotate, so as to realize the control of the rotation of the winding roller 15 .

[0071] The drive motor 6 is fixedly mounted on the outer wall of the mounting frame 1, and the output shaft of the drive motor 6 is fixedly connected to the axial end of the control worm 31. The drive motor 6 is used to drive the rotation of the control worm 31, thereby providing power for the rotation of the winding roller 15. In this embodiment, the transmission is coordinated by the control worm 31 and the control worm wheel 30, and the unidirectional transmission characteristic is utilized to improve the stability and safety during the lifting of the pile barrel.

[0072] As a preferred embodiment of the present invention, the diversion mechanism includes a storage box 11, a diversion groove 14 and a guide tube 32, wherein the interior of the storage box 11 is used to store the curing liquid, and a liquid injection port is provided on the upper part, and the liquid injection hole is closed by a detachable cap.

[0073] The guide groove 14 is provided at the upper end of the mounting frame 12 and is communicated with the inner cavity of the mounting frame 12 . The curing liquid is slowly injected into the guide groove 14 , and the curing liquid naturally seeps and the capillary action realizes the wetting of the smear strip 13 .

[0074] The storage box 11 is fixedly mounted on the inner wall of the mounting frame 1, one end of the guide tube 32 is connected to the bottom of the storage box 11, and an electronic valve is provided at any position in the guide tube 32 for controlling the other end of the guide tube 32 to be located directly above the guide groove 14. The curing liquid in the storage box 11 is controlled by the electronic valve to gradually drip into the guide groove 14, so that the smear strip 13 can absorb the curing liquid.

[0075] A mounting block 18 is slidably mounted on the side wall of the mounting frame 1, and the outer wall of the mounting block 18 is slidably fitted with the inner wall of the mounting frame 1. The side wall of the mounting block 18 is connected to the inner wall of the mounting frame 1 through an elastic member, and the elastic member is a spring. One end of the spring is connected to the mounting block 18, and the other end of the mounting block 18 is connected to the mounting frame 1. The elastic force of the spring pushes the mounting block 18 so that the mounting block 18 has a real-time tendency to move toward the direction of the winding roller 15.

[0076] Two mounting blocks 18 are provided, and one axial end of the support plate 22 is rotatably connected to one of the mounting blocks 18 via a connecting shaft. Through the elastic force exerted on the mounting block 18, the support plate 22 and the cleaning roller 10 have a tendency to approach the winding roller 15 in real time, so as to facilitate the cleaning roller 10 to wipe the traction cable 3 and maintain the wiping effect.

[0077] As a preferred embodiment of the present invention, a support tube 2 is fixedly installed in the middle of another mounting block 18 , and a mounting disk 25 is rotatably installed on the radial outer wall of the support tube 2 . The support tube 2 is a hollow structure and provides support for the mounting disk 25 .

[0078] One end of the support tube 2 extends to the inner cavity of the cleaning roller 10, and a top pressure strip 27 is fixedly installed on the radial outer wall of the support tube 2. The top pressure strip 27 slides and fits with the inner wall of the cleaning roller 10 at one end away from the support tube 2. During the rotation of the support plate 22, the top pressure strip 27 is kept toward the winding roller 15, and the top pressure strip 27 is kept toward the wiping position when the cleaning roller 10 wipes the traction cable 3.

[0079] The inner wall of the top pressure strip 27 is provided with a through hole interconnected with the inner cavity of the support tube 2, connecting the support tube 2 with an external negative pressure chamber, thereby generating negative pressure inside the support tube 2, so that the cleaning roller 10 absorbs excess curing liquid on the outer wall of the traction steel cable 3 when wiping the traction steel cable 3, so as to facilitate the recovery of the curing liquid and prevent the curing liquid on the outer wall of the traction steel cable 3 from dripping and wasting due to excessive amount of curing liquid.

[0080] A transmission wheel 16 is fixedly mounted on one axial end of the winding roller 15 , and the transmission wheel 16 is driven to rotate synchronously during the rotation of the winding roller 15 .

[0081] A driven wheel 24 is fixedly mounted on the axial end of the support disc 22 . The driving wheel 16 is connected to the driven wheel 24 via a belt. When the belt is tensioned, the driving wheel 16 drives the driven wheel 24 to rotate, thereby driving the support disc 22 and the cleaning roller 10 to rotate.

[0082] A tensioning wheel 23 is elastically connected to the inner wall of the mounting frame 1, and the radial outer wall of the tensioning wheel 23 is in real-time contact with the outer wall of the belt. A swing arm is installed on the outer wall of the mounting frame 1 through a torsion spring, and the other end of the swing arm is connected to the tensioning wheel 23. The elastic force of the torsion spring allows the tensioning wheel 23 to keep the belt in a tensioned state to accommodate the movement of the cleaning roller 10.

[0083] An elastic frame is disposed on the outer wall of the mounting block 18 connected to the support plate 22, and a collecting bucket 9 is fixedly connected to the other end of the elastic frame. The elastic frame is provided with an elastic copper plate.

[0084] The outer wall of the collecting hopper 9 is in close contact with the radial outer wall of the cleaning roller 10 . When the cleaning roller 10 rotates, the outer wall of the collecting hopper 9 scrapes the outer wall of the cleaning roller 10 , thereby collecting impurities stuck to the outer wall of the cleaning roller 10 .

[0085] The inner wall of the collecting bucket 9 is obliquely provided with a guide plate 21 . When the collecting bucket 9 presses against the cleaning roller 10 , an oblique indentation is formed on the cleaning roller 10 , thereby maintaining the cleaning efficiency of the scraping cleaning roller 10 .

[0086] As a preferred embodiment of the present invention, a connecting pipe 26 is fixedly mounted on the side wall of the mounting plate 25 , and an exhaust port is formed on the outer wall of the connecting pipe 26 .

[0087] The connecting tube 26 extends to the inner wall of the cleaning roller 10. When the connecting tube 26 rotates to above the collecting bucket 9, air is inflated into the mounting plate 25. At this time, the gas is exhausted through the exhaust port outside the connecting tube 26, thereby assisting the impurities sticking to the outer wall of the collecting bucket 9 to fall off, keeping the outer wall of the cleaning roller 10 clean, and being used to improve the efficiency of cleaning the traction cable 3. At the same time, when the air is exhausted from the inside of the cleaning roller 10 to the outside, it helps the cleaning roller 10 to recover its elasticity, further maintaining the cleaning efficiency of the cleaning roller 10.

[0088] The inner wall of the mounting disk 25 is elastically mounted with a closing plug 33 for sealing the connecting tube 26, wherein a plurality of connecting tubes 26 are evenly arranged along the axis of the mounting disk 25, and the closing plug 33 is connected to the mounting disk 25 via a spring. As the mounting disk 25 rotates, the plurality of connecting tubes 26 gradually approach the contact position between the collecting bucket 9 and the cleaning roller 10 in turn. When the connecting tube 26 is located above the collecting bucket 9, the corresponding closing plug 33 is slid to allow the connecting tube 26 to conduct exhaust, so as to facilitate collection by the collecting bucket 9 and achieve the cleaning of the cleaning roller 10 itself.

[0089] A mounting plate 29 is fixedly mounted on the inner wall of the mounting frame 1, and an attraction block 20 for attracting the closing plug 33 is fixedly mounted on the outer wall of the mounting plate 29, wherein an iron block is embedded inside the closing plug 33, and the attraction block 20 is a common magnet. When the closing plug 33 moves to a position corresponding to the attraction block 20, the closing plug 33 is separated from the connecting pipe 26 by magnetic attraction, thereby achieving conduction of the corresponding connecting pipe 26.

[0090] A control pump 8 is fixedly mounted on the outer wall of the mounting frame 1 , and the output end of the control pump 8 is connected to the inner cavity of the storage box 11 . A hose is provided at the output end of the control pump 8 , and the other end of the hose is connected to the storage box 11 .

[0091] An air release nozzle 7 is fixedly mounted on the upper end surface of the storage box 11 , and the air release nozzle 7 is used to maintain the air pressure balance in the inner cavity of the storage box 11 .

[0092] The input end of the control pump 8 is connected to the axial end of the support tube 2. The control pump 8 provides negative pressure to the inner wall of the support tube 2, thereby absorbing the curing liquid inside the support tube 2 and returning it to the inner cavity of the storage box 11, thereby realizing the recycling of the curing liquid.

[0093] In this embodiment, since the top pressure strip 27 is in an extrusion position with the traction steel cable 3, this part of the cleaning roller 10 is squeezed and deformed, thereby making the holes of the cleaning roller 10 itself smaller, thereby improving the filtering effect of the curing liquid when the curing liquid enters the interior of the support tube 2, thereby improving the quality of the recovered curing liquid.

[0094] The upper end surface of the mounting frame 1 is fixedly mounted with a transfer tube 17 , the inner cavity of the transfer tube 17 is elastically mounted with a floating plug 28 , the upper end of the floating plug 28 is provided with a spring, and the other end of the spring is connected to the inner wall of the transfer tube 17 .

[0095] An adapter ring 19 is rotatably mounted on the radial outer wall of the mounting plate 25. The outer wall of the adapter ring 19 is connected to the inner cavity of the adapter tube 17 through a conduit. The other side of the adapter tube 17 is connected to the air vent nozzle 7. When the control pump 8 injects air and curing liquid into the storage box 11, the air pressure in the inner cavity of the storage box 11 increases. At this time, the air vent nozzle 7 discharges the gas from the inner cavity of the adapter tube 17. When the connecting tube 26 is turned on, the gas is discharged from the connecting tube 26 to realize the recoil cleaning of the cleaning roller 10.

[0096] The setting of the adapter tube 17 and the floating plug 28 is to provide a buffer space for the gas when the non-connecting tube 26 is connected, so as to maintain the stability of the overall structure.

[0097] like Fig.14 As shown, a construction method of bored piles, the method adopts the above-mentioned bored pile construction device, and comprises the following steps:

[0101] A4. When the reel 15 controls the reeling and releasing of the traction cable 3 , the cleaning roller 10 is driven to rotate synchronously, and the collecting bucket 9 scrapes the outer wall of the cleaning roller 10 .
