Description

Technical Field

[0001] The present application relates to the field of underground building construction technology, and in particular to a miniaturized multifunctional pile driver. Background Art

[0002] As cities continue to expand, land for urban construction is becoming increasingly scarce. To alleviate this land shortage and fully utilize space, underground structures are developing in a trend toward height, size, and depth. Pile drivers are a common piece of equipment used in underground construction projects. They are primarily used to form pile holes, allowing concrete to be poured into the holes later in the construction process, ultimately forming concrete piles.

[0003] When the pile driver is operating, it is necessary to first clamp a single section of casing, drive the single section of casing into the ground, and then send the soil in the casing out through the rotating spiral rod. The power head of the pile driver then docks with the new casing, and then clamps the new casing and transports it to the piling position. The pile driver operates to drive the new casing into the ground, pressing it onto the previous casing, and then loosens the soil again through the spiral rod; repeat the above steps to press multiple casings end to end to meet the designed elevation of the pile hole, thereby completing the pile hole forming operation.

[0004] In actual operations, in order to improve construction efficiency and shorten the construction process, the length of a single section of casing is often set longer in the project, thereby shortening the time for the pile driver's power head to connect with the casing and transport it. However, this method requires the pile driver's pile frame to be set very high, so that the power head can clamp and fix the entire casing. In order to support the high pile frame, the support base at the bottom of the pile driver also needs to be more adaptable to ensure the stability of the pile frame when it is located on the support base. However, when carrying out construction in old urban areas, due to the very limited distance between buildings, under this restriction, it is difficult for the above-mentioned pile driver to enter the construction site, which has certain limitations. Utility Model Content

[0005] In order to improve the problems existing in the above-mentioned technology, the present application provides a miniaturized multifunctional pile driver.

[0006] The present application provides a miniaturized multifunctional pile driver adopting the following technical solutions:

[0007] A miniaturized multifunctional pile driver includes a support base, a slewing mechanism for driving the support base to rotate is provided at the bottom of the support base, two columns are vertically provided on the support base, a first power head is slidably provided on the columns, and a first driving part is provided on the support base for driving the first power head to slide vertically on the corresponding columns respectively, and a clamp is provided on the first power head for clamping and fixing the casing.

[0008] By adopting the above technical solution, when the pile-forming operation is carried out, the two first power heads respectively clamp and fix two casings through the clampers, one of which is docked with the pile-forming position, and the first power head where the casing docked with the pile-forming position is located is driven by the first driving part to slide down on the column, and the first power head drives the clamper to slide until the bottom of the casing abuts against the ground and is pressed into the ground. After that, the clamper then releases the clamping of the casing, so that the casing is buried in the ground, and the support seat is driven to rotate by the rotary mechanism. At this time, the casing clamped by the first power head on the other column will follow the support seat to rotate to dock with the pile-forming position, and the first driving part drives this first power head to slide down so that the casing is pressed into the top of the casing already buried in the ground; repeat the above steps to press multiple casings end to end in the ground, thereby meeting the designed elevation of the pile hole.

[0009] In the above process, through the joint cooperation of the two columns, after the current casing is buried in the ground, the subsequent casing follows the rotation of the columns and can quickly dock with the previous casing, and the first power head corresponding to the previous casing can clamp and fix the new casing while the other first power head presses the casing into the ground, thereby shortening the time for docking and transportation of the pile driver as a whole with the casing, improving construction efficiency and shortening the construction process; and by integrating the two columns into one pile driver, the required height of the columns can be reduced, the overall structure of the pile driver is more compact, the pile driver occupies less space during pile operation, placement and transportation, and under the premise of limited distance between buildings, the pile driver can still enter the construction site to operate, thereby making the use of the pile driver more flexible and convenient, and able to adapt to different construction needs.

[0010] Optionally, a second power head is slidably provided on the column, and the second power head is located above the corresponding first power head. A spiral rod is rotatably provided on the second power head. The support seat is provided with a second driving part for driving the second power head to slide vertically on the corresponding column. The first power head is provided with an avoidance groove for the corresponding spiral rod to pass through and be inserted into the casing.

[0011] By adopting the above technical solution, after the first power head operates to press the casing into the ground, the second drive unit drives the corresponding second power head to slide down, and the second power head simultaneously drives the screw rod to rotate. The screw rod moves downward while rotating, and the screw rod is inserted into the casing through the avoidance groove. The rotation of the screw rod then sends the soil in the casing out, thereby completing the pile hole forming operation; the avoidance groove and the casing cooperate so that the screw rod can pass through the avoidance groove and be partially located in the casing when it is not drilled into the ground. The entire screw rod does not need to be completely exposed to the outside, thereby partially overlapping the space for placing the screw rod and the casing, thereby further reducing the required height of the column. In addition, when the casing is pressed into the ground, the screw rod can also be directly drilled into the casing on the ground, without the need to dock with the casing in the ground, thereby further improving construction efficiency.

[0012] Optionally, the column is hinged to the support base, and two pull rods are hinged on the support base. The two pull rods are respectively connected to the two columns. A third driving part is provided on the support base, and the third driving part is used to drive the pull rods from a horizontal state to a vertical state.

[0013] By adopting the above technical solution, the pull rod is used to pull the column, and the third drive unit drives the pull rod to rotate, thereby enabling the pull rod to be converted from a horizontal state to a vertical state. When the pile driver is used, the third drive unit can drive the pull rod from a vertical state to a horizontal state, and the column can thereby be converted to a horizontal state, thereby facilitating the placement of the pile driver and reducing the space required for placement of the pile driver.

[0014] Optionally, an auxiliary support frame is provided on the support seat, and two steel ropes are provided on the auxiliary support frame, and the two steel ropes are respectively connected to two pull rods.

[0015] By adopting the above technical solution, the two steel wire ropes on the auxiliary support frame are used to pull the two pull rods respectively, thereby improving the stability of the pull rods when they are located on the support seat.

[0016] Optionally, a pulley is rotatably provided on the top of the column, and the first driving unit includes a first winch provided on the support seat, and a hoisting rope of the first winch passes through the pulley and is connected to the first power head.

[0017] By adopting the above technical solution, when the first power head needs to be driven to slide down on the column, the first winch is operated to release the winch rope, and the winch rope passes through the pulley and is connected to the first power head. During the sliding of the first power head, the pulley rotates, thereby making the winch rope smoother when released and pulled; the first winch and the pulley work together to complete the mobile drive of the first power head. The first winch and the pulley occupy less space on the support seat, making the overall structure of the pile driver more compact.

[0018] Optionally, an auxiliary wheel opposite to the pulley is rotatably provided on the top of the column, and the hoisting rope of the first hoist passes through the auxiliary wheel.

[0019] By adopting the above technical solution, the hoisting rope of the first winch passes through the pulley and the auxiliary wheel at the same time. During the entire process of the hoisting rope being released and pulled, the auxiliary wheel and the slide bar are in contact with the hoisting rope and rotate. The two rotating wheels work together to improve the stability of the hoisting rope during the release process.

[0020] Optionally, a vertical slide rail is provided on the column, and a slider is provided on the first power head. The slider is located on the vertical slide rail and is slidably connected to the vertical slide rail.

[0021] By adopting the above technical solution, the hoisting rope of the first winch is released to allow the first power head to slide down. During the entire sliding process of the first power head, the slider is located on the vertical slide rail and slides. The vertical slide rail and the slider work together to limit the sliding direction of the first power head, thereby avoiding dislocation of the first power head during the sliding process and improving the stability of the first power head during the sliding process.

[0022] Optionally, an auxiliary winch is provided on the support seat.

[0023] By adopting the above technical solution, the auxiliary winch is set on the support seat for backup. When the first winch is worn or damaged after a long period of operation, the auxiliary winch can be used to drive the movement of the first power head, thereby avoiding the pile driver having to stop for maintenance due to damage to parts during operation, which consumes a lot of time.

[0024] Optionally, the two columns are symmetrically distributed on the support base.

[0025] By adopting the above technical solution, the two columns are symmetrically distributed on the support base, so that the weight on the support base is evenly distributed, thereby improving the stability of the support base during operation and avoiding shaking of the support base during operation due to uneven weight distribution.

[0026] Optionally, a walking mechanism for driving the support base to move is provided at the bottom of the support base, and the slewing mechanism is provided between the walking mechanism and the support base.

[0027] By adopting the above technical solution, the walking mechanism is arranged at the bottom of the support seat to drive the support seat to move, thereby making the use of the pile driver more flexible.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Through the cooperation of the two columns, after the current casing is buried in the ground, the subsequent casing can rotate with the columns and quickly dock with the previous casing, and the first power head corresponding to the previous casing can clamp and fix the new casing while the other first power head presses the casing into the ground, thereby shortening the time for docking and transporting the pile driver with the casing, improving construction efficiency and shortening the construction process; and by integrating the two columns into one pile driver, the required height of the columns can be reduced, the overall structure of the pile driver is more compact, and the space occupied by the pile driver during pile operation, placement and transportation is smaller. Under the premise of limited distance between buildings, the pile driver can still enter the construction site for operation, thereby making the use of the pile driver more flexible and convenient, and able to adapt to different construction needs;

[0030] 2. The coordination of the avoidance groove and the casing allows the screw rod to pass through the avoidance groove and partially lie in the casing when not drilled into the ground. The entire screw rod does not need to be completely exposed, thereby partially overlapping the space for placing the screw rod and the casing, thereby further reducing the required height of the column. In addition, when the casing is pressed into the ground, the screw rod can also be drilled directly into the casing on the ground, eliminating the need for docking with the casing in the ground, thereby further improving construction efficiency;

[0031] 3. The pull rod is used to pull the column, and the third drive unit drives the pull rod to rotate, thereby enabling the pull rod to be converted from a horizontal state to a vertical state, thereby enabling the column to be converted from a horizontal state to a vertical state for operation. When the pile driver is finished using, the third drive unit can drive the pull rod from a vertical state to a horizontal state, thereby enabling the column to be converted to a horizontal state, thereby facilitating the placement of the pile driver and reducing the space required for placement of the pile driver.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 This application is described in further detail.

[0035] The embodiment of the present application discloses a miniaturized multifunctional pile driver. Figure 1The miniaturized multifunctional pile driver includes a support base 1. A slewing mechanism 2 is provided at the bottom of the support base 1 for driving the support base 1 to rotate. Two columns 3 are vertically arranged on the support base 1. The two columns 3 are symmetrically distributed on the support base 1. A first power head 4 is slidably provided on the column 3. A first driving part is provided on the support base 1 for driving the first power head 4 to slide vertically on the corresponding column 3. A clamp 6 for clamping a fixed casing 5 is provided on the first power head 4.

[0036] A walking mechanism is provided at the bottom of the support base 1 for driving the support base 1 to move. The walking mechanism is selected as a crawler machine 19. The slewing mechanism 2 is arranged between the crawler machine 19 and the support base 1. The slewing mechanism 2 can be selected as a driving motor. The support base 1 is driven to rotate by the rotation of the output shaft of the driving motor, and the operation of the crawler machine 19 can drive the slewing mechanism 2 and the support base 1 to move, making the use of the pile driver more flexible.

[0037] The first driving part includes two first winches 7 arranged on the support base 1, and the two first winches 7 are symmetrically distributed on the support base 1. A pulley 15 and an auxiliary wheel 16 are rotatably arranged on the top of the two columns 3, and the pulley 15 and the auxiliary wheel 16 are arranged opposite to each other; a lifting lug is fixed on the first power head 4, and the hoisting rope of the first winch 7 passes through the corresponding pulley 15 and the auxiliary wheel 16, and is fixedly connected to the lifting lug on the corresponding first power head 4.

[0038] When it is necessary to drive the first power head 4 to slide down on the column 3, the first winch 7 is operated to release the winch rope, and the winch rope passes through the pulley 15 and is connected to the first power head 4. During the sliding of the first power head 4, the pulley 15 rotates, thereby making the winch rope smoother when released and pulled; the first winch 7 and the pulley 15 work together to complete the mobile drive of the first power head 4. The first winch 7 and the pulley 15 occupy less space on the support base 1, making the overall structure of the pile driver more compact.

[0039] A second power head 10 is slidably mounted on the column 3. The second power head 10 is located above the corresponding first power head 4. A screw rod 11 is rotatably mounted on the second power head 10. The support base 1 is provided with a second driving portion for driving the second power head 10 to slide vertically on the corresponding column 3. The first power head 4 is provided with an escape groove for the corresponding screw rod 11 to pass through and be inserted into the casing 5. The second driving portion includes two second winches 8 mounted on the support base 1. The two second winches 8 are symmetrically distributed on the support base 1. A lifting lug is fixed to the second power head 10. The hoisting rope of the second winch 8 passes through the corresponding pulley 15 and auxiliary wheel 16, and is fixedly connected to the lifting lug on the corresponding second power head 10.

[0040] When the first power head 4 operates to press the casing 5 into the ground, the second winch 8 drives the corresponding second power head 10 to slide down, and the second power head 10 simultaneously drives the screw rod 11 to rotate. The screw rod 11 moves downward while rotating, and the screw rod 11 is inserted into the casing 5 through the avoidance groove. The rotation of the screw rod 11 then sends the soil in the casing 5 out, thereby completing the pile hole forming operation; the avoidance groove and the casing 5 cooperate so that the screw rod 11 can pass through the avoidance groove and be partially located in the casing 5 when it is not drilled into the ground. The entire screw rod 11 does not need to be completely exposed to the outside, thereby partially overlapping the space for placing the screw rod 11 and the space for placing the casing 5, thereby further reducing the required height of the column 3. In addition, when the casing 5 is pressed into the ground, the screw rod 11 can also be directly drilled into the casing 5 on the ground, without the need to dock with the casing 5 in the ground.

[0041] A vertical slide rail 17 is fixed on the column 3, and a slider 18 is fixed on each of the first power head 4 and the second power head 10. The slider 18 is located on the corresponding vertical slide rail 17 and is slidably connected to the vertical slide rail 17. The hoisting rope of the first hoist 7 is released to allow the first power head 4 to slide down, and the hoisting rope of the second hoist 8 is released to allow the second power head 10 to slide down. During the entire sliding process of the first power head 4 and the second power head 10, the slider 18 is located on the vertical slide rail 17 and slides. The vertical slide rail 17 and the slider 18 cooperate with each other to limit the sliding direction of the first power head 4 and the second power head 10, thereby preventing the first power head 4 and the second power head 10 from being misaligned during the sliding process and improving the stability of the first power head 4 and the second power head 10 during the sliding process.

[0042] Both columns 3 are hinged to the support base 1. Two pull rods 12 are hinged to the support base 1. The ends of the two pull rods 12 away from the support base 1 are fixed to the middle of the corresponding columns 3. The support base 1 is provided with a third drive unit, which is used to drive the pull rods 12 from a horizontal state to a vertical state. The third drive unit is selected as a third winch 9. The hoisting rope of the third winch 9 is fixed to the pull rods 12. The operation of the third winch 9 controls the retraction and extension of the hoisting rope, thereby allowing the pull rods 12 to switch between a horizontal state and a vertical state. The pull rods 12 are used to pull the columns 3, thereby enabling the columns 3 to switch from a horizontal state to a vertical state for operation. When the pile driver is finished using, the third winch 9 operates to drive the pull rods 12 from a vertical state to a horizontal state. The columns 3 can thus be converted to a horizontal state, thereby facilitating the placement of the pile driver and reducing the space required for placement of the pile driver.

[0043] An auxiliary support frame is provided on the support seat 1, and two steel wire ropes 14 are provided on the auxiliary support frame. The two steel wire ropes 14 are respectively connected to the two pull rods 12; the two steel wire ropes 14 on the auxiliary support frame are used to pull the two pull rods 12 respectively, thereby improving the stability of the pull rods 12 when they are located on the support seat 1.

[0044] The two first power heads 4 are also equipped with a vibration damper. When the first power heads 4 slide down to make the bottom of the casing 5 contact the ground, the vibration damper then operates, allowing the casing 5 to be pressed into the ground more smoothly. The support base 1 is also equipped with an auxiliary winch. The auxiliary winch is set on the support base 1 for backup. When the first winch 7, the second winch 8 or the third winch 9 are worn or damaged after long-term operation, the auxiliary winch can be used to replace them. This avoids the pile driver having to stop for maintenance due to damage to parts during operation, which consumes a lot of time.

[0045] After the pile is formed, the first power head 4 is driven by the first winch 7 to slide down on the column 3, and the first power head 4 drives the clamp 6 to slide until the bottom of the casing 5 contacts the ground and is pressed into the ground. After that, the clamp 6 releases the clamp of the casing 5, so that the casing 5 is buried in the ground. The support seat 1 is driven to rotate by the rotary mechanism 2. At this time, the casing 5 clamped by the first power head 4 on the other column 3 will follow the support seat 1 to rotate to the pile forming position. The first winch 7 then drives the first power head 4 to slide down so that the casing 5 is pressed into the top of the casing 5 already buried in the ground. The above steps are repeated to press the multiple casings 5 ​​end to end in the ground, thereby meeting the designed elevation of the pile hole.

[0046] When the pile driver is in the working state, the pile loader 3 is in the working state, and the pile driver 3 is in the working state, so that the pile driver 3 can move forward and backward, and the pile driver 3 can move backward and forward to the working state, thereby shortening the time for the pile driver to move forward and backward, and improving the construction efficiency and shortening the construction process. Moreover, by integrating the two columns 3 into one pile driver, the required height of the columns 3 can be reduced, the overall structure of the pile driver can be more compact, and the space occupied by the pile driver during pile forming, placement and transportation is smaller. Under the premise of limited distance between buildings, the pile driver can still enter the construction site to operate, thereby making the use of the pile driver more flexible and convenient, and able to adapt to different construction needs.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
