As shown in fig. 1 to 8, a pile hole soil cleaning device includes:
A working rod 1, the lower end of which is a cleaning end provided with a helical blade 101, and the upper end of which serves as a driving end;
a driving module 2 connected to the working rod 1 for driving the working rod 1 to lift or rotate, and
An auxiliary module connected to the drive module 2 and for suspending the drive module 2 above the stake hole.
The soil cleaning operation of the pile hole can be divided into two parts, wherein the pile hole is taken as a boundary, the soil in the pile hole is dug through a tool during the soil taking operation, and the soil attached to the tool is cleaned after the soil taking operation, so that the soil cleaning operation of the pile hole is realized through the cyclic reciprocation of the soil taking operation and the soil dumping operation.
In the pile hole soil-cleaning operation device, soil-taking operation is completed mainly through the cooperation of the operation rod 1 and the driving module 2, specifically, when the pile hole soil-cleaning operation device is erected above a pile hole, the driving module 2 drives the operation rod 1 to descend until the spiral blade 101 abuts against soil in the pile hole, the driving module 2 drives the operation rod 1 to rotate again, and the auxiliary module drives the operation rod 1 and the driving module 2 to integrally descend, so that the spiral blade 101 moves downwards and cuts into the soil. In other words, the soil is divided into a portion located above the spiral blade 101 and a portion located below the spiral blade 101. The driving module 2 drives the working rod 1 to ascend again until the spiral blade 101 and soil thereon move out of the pile hole. Thus, the soil sampling operation is completed.
It is worth noting that for the distance of the auxiliary module driving downward movement, the distance should be confirmed according to the actual working condition, so that the soil taken out by the pile hole soil cleaning device each time is ensured not to be overweight, and the service life of the pile hole soil cleaning device is prolonged.
The soil pouring operation is completed through the auxiliary module, namely, after the spiral blade 101 and soil on the spiral blade move out of the pile hole, the soil is moved out of the projection range of the pile hole through the auxiliary module, and the soil on the spiral blade 101 is removed through manpower and/or tools. Finally, the helical blade 101 is moved back to the position above the pile hole so as to facilitate the next soil taking operation.
The following describes the operation of the pile hole soil cleaning operation device in combination with the structure of each functional module:
In one possible implementation, the drive module 2 comprises a housing 201, a first drive unit 202 and a second drive unit 203;
The box 201 is provided with a working hole which is adapted to the working rod 1 and a partition board which is positioned in the box 201, and correspondingly, the working rod 1 is arranged in the working hole in a penetrating way, and the first driving unit 202 and the second driving unit 203 are respectively arranged on the upper side and the lower side of the partition board;
The first driving unit 202 is used for driving the working rod 1 to reciprocate, the second driving unit 203 is used for driving the working rod 1 to rotate, and the first driving unit 202 and the second driving unit 203 alternately work.
Based on the above design, the case 201 is used for providing an installation space so as to integrate the first driving unit 202 and the second driving unit 203, so that the driving module 2 can output two motions of lifting and rotating to the working rod 1, and the first driving unit 202 and the second driving unit 203 alternately work to avoid that the two driving units simultaneously drive the working rod 1to move, thereby protecting the driving module 2.
Meanwhile, the first driving unit 202 and the second driving unit 203 are separated by a partition plate to avoid interference therebetween, and in addition, the case 201 may be constructed in any suitable structure, to which the present invention is not limited.
As for the first driving unit 202, optionally, as shown in fig. 3, the first driving unit 202 includes a first driver 204, a turntable 205, and a driving structure;
The first driver 204 is arranged in the box 201, and the output end of the first driver 204 is connected with the turntable 205 and is used for driving the turntable 205 to rotate;
The circumference of the rotary table 205 is opposite to the working rod 1 and is provided with a driving structure, the driving structure is provided with a plurality of lifting grooves 102 which are equally spaced on the circumference of the rotary table 205, and correspondingly, the working rod 1 is provided with a lifting groove 102 which is adapted to the driving structure;
the driving structure comprises an inner groove positioned on the turntable 205, a rotating shaft 206 arranged in the inner groove and a driving rod 207 arranged on the rotating shaft 206 through torsion spring rotation, wherein the inner groove is constructed as a unidirectional through groove which is axially through along the turntable 205 and is provided with an inner wall along the circumference of the turntable 205, and the upper end and the lower end of the driving rod 207 are respectively abutted against the inner wall of the inner groove;
when the working rod 1 rotates, the driving rod 207 rotates out of the inner groove under the driving of the working rod 1, and accordingly, the lifting groove 102 has an inclined surface arranged along the circumferential direction of the working rod 1.
Based on the above design, the power of the first driver 204 is transferred to the driving structure via the turntable 205, and the driving structure is connected to the working rod 1 and drives the working rod 1 to lift. In the driving structure, at least one driving rod 207 is inserted into the lifting groove 102 on the working rod 1, and the driving rod 207 rotates along with the turntable 205 and drives the working rod 1 to lift.
Correspondingly, the lifting grooves 102 are arranged in a plurality of ways and are equally spaced along the axial direction of the working rod 1, so that the first driving unit 202 drives the whole working rod 1 to lift, and the height of each lifting groove 102 is larger than that of the driving rod 207, so that the driving rod 207 can be more conveniently inserted into the lifting groove 102. Then, when the working bar 1 is lifted, one of the driving bars 207 is inserted into one of the lifting grooves 102, the driving bar 207 abuts against the upper wall surface of the lifting groove 102 and drives the working bar 1 to lift, and when the working bar 1 is lifted, one of the driving bars 207 is inserted into one of the lifting grooves 102, the driving bar 207 abuts against the upper wall surface of the lifting groove 102 and controls the lifting speed of the working bar 1.
Meanwhile, as the working rod 1 rotates under the action of the second driving unit 203, in the driving structure, the driving rod 207 is rotatably arranged on the rotating shaft 206 through the torsion spring, so that the driving rod 207 can rotate, the inner groove is axially penetrated along the turntable 205, the lifting groove 102 is provided with an inclined plane arranged along the circumferential direction of the working rod 1, the former is used for providing a rotating space for the driving rod 207 (i.e. the driving rod 207 can rotate to the outside of the turntable 205), and the latter uses the rotation of the working rod 1 as power to drive the driving rod 207 to rotate. Based on this, when the work bar 1 rotates, the driving lever 207 can be rotated along the inclined surface of the elevation groove 102 to avoid blocking the rotation of the work bar 1. When the working rod 1 stops rotating and the lifting groove 102 is opposite to the turntable 205, the driving rod 207 is reset under the action of the torsion spring and is inserted into the lifting groove 102.
In addition, the upper and lower ends of the driving rod 207 are respectively abutted against the inner wall of the inner groove, so that accidental disturbance of the driving rod 207 in the transmission process is reduced, and the transmission efficiency is improved.
As for the second driving unit 203, optionally, as shown in fig. 3 to 6, the second driving unit 203 includes a second driver, a worm 208, a worm wheel 209, and a control member 210;
The second driver is arranged in the box 201, the output end of the second driver is connected with the worm 208, the worm 208 is connected with the worm wheel 209, the worm wheel 209 is sleeved on the working rod 1, and the control piece 210 is arranged on the partition plate and used for controlling the connection between the worm wheel 209 and the working rod 1;
accordingly, when the worm wheel 209 is coupled to the work bar 1, the second driving unit 203 drives the work bar 1 to rotate, and the control member 210 serves as a transmission key.
Based on the design scheme, the worm and gear structure is used for transmitting power, and the acting force direction is changed so as to drive the operation rod 1 to rotate. Meanwhile, the control member 210 is used for controlling the connection relation, namely, when the control member 210 is connected with the worm gear 209 and the working rod 1, the power of the second driver can be transmitted to the working rod 1 to enable the working rod 1 to rotate, at the moment, the driving rod 207 in the first driving unit 202 rotates outside the rotary table 205, otherwise, when the control member 210 is disconnected with the worm gear 209 and the working rod 1, the power of the second driver cannot be transmitted to the working rod 1, namely, the working rod 1 is driven by the first driving unit 202 to lift, at the moment, the working rod 1 should be rotated in advance until the lifting groove 102 of the working rod is opposite to the rotary table 205, and the connection relation of the control member 210 is released.
Alternatively, as shown in fig. 3-6, the control member 210 includes a control ring 211 and a telescoping rod 212;
The control ring 211 is parallel to the worm gear 209 and has an annular surface parallel to the worm gear 209, and the annular surface is provided with a guide rod 213 penetrating through the partition plate; the control ring 211 is provided with an inner peripheral surface sleeved on the working rod 1, the inner peripheral surface of the control ring 211 is provided with a concave annular groove and a movable ring 214 rotatably arranged on the annular groove, and the inner peripheral surface of the movable ring 214 is provided with a transmission rod 215 extending along the axial direction of the working rod 1;
The telescopic rod 212 is arranged on the partition plate, and the working end of the telescopic rod 212 is connected with the annular surface of the control ring 211;
Correspondingly, a first concave rotating groove 216 is formed in the worm gear 209, a second concave rotating groove 103 is formed in the working rod 1, and the transmission rod 215 is arranged on the second rotating groove 103 in a sliding mode;
correspondingly, the telescopic rod 212 is used for driving the control ring 211 to lift relative to the worm gear 209, so that the transmission rod 215 is inserted into or separated from the first rotary groove 216.
Based on the above design, the telescopic rod 212 drives the control ring 211 to lift, when the control ring 211 approaches the worm gear 209, the transmission rod 215 slides along the second rotation groove 103 and is inserted into the first rotation groove 216, so as to realize connection between the worm gear 209 and the working rod 1, and at this time, the control member 210 is used as a transmission key. Conversely, when the control ring 211 is far away from the worm wheel 209, the transmission rod 215 slides along the second rotation groove 103 and is separated from the first rotation groove 216, and the worm wheel 209 is disconnected from the work rod 1.
Meanwhile, the guide rods 213 are arranged on the partition board in a penetrating way, and the lifting direction of the control ring 211 is guided by the mutual matching of the guide rods 213 and the partition board, so that the whole control ring 211 is ensured to synchronously lift.
Notably, when the worm gear 209 is coupled to the work bar 1 via the control member 210, i.e., the work bar 1 is rotatable, the control ring 211 will remain relatively stationary, while the moving ring 214 and the drive rod 215 rotate synchronously while transmitting force to avoid other portions of the control member 210 from preventing rotation of the work bar 1.
Preferably, as shown in fig. 3 and 4, the worm gear 209 is disposed above the partition (i.e., the second driving unit 203 is disposed above the partition, the first driving unit 202 is disposed below the partition), a bracket 219 for supporting the worm gear 209 is disposed on the partition, the worm gear 209 is suspended above the partition to reduce the contact surface between the worm gear 209 and the partition, and a contact surface with a small friction coefficient is disposed between the bracket 219 and the worm gear 209 to reduce the wear of the worm gear 209 during rotation.
Suitably, the control element 210 may be disposed above the partition and staggered from the support 219, or the control element 210 is disposed below the partition, where the former helps to shorten the distance between the control element 210 and the worm gear 209, but the local structure is too complex, and the latter has a more compact structure, but the distance between the control element 210 and the worm gear 209 increases, so that the size of the control element 210, such as the length of the transmission rod 215, the lifting height of the telescopic rod 212, etc., may all be increased to some extent.
Optionally, as shown in fig. 6, the control ring 211 is further provided with a third driver 217 and a transmission gear 218, an output end of the third driver 217 penetrates into the control ring 211 and is connected to the transmission gear 218, and the transmission gear 218 is rotatably arranged in the control ring 211 and is meshed with the outer periphery of the movable ring 214;
correspondingly, the outer periphery of the movable ring 214 is provided with tooth surfaces adapted to the transmission gear 218;
accordingly, the third driver 217 is used to drive the rotating ring 214 to rotate so as to align the first rotating groove 216 with the second rotating groove 103.
Based on the above design, when the pile hole soil cleaning device is accidentally disturbed, the working rod 1 rotates and causes the first rotating groove 216 and the second rotating groove 103 to be staggered, and the transmission rod 215 cannot be inserted into the first rotating groove 216. In this regard, the control ring 211 is provided with a third driver 217 and a transmission gear 218, the transmission gear 218 is driven to rotate by the third driver 217, the transmission gear 218 drives the movable ring 214 to rotate, and the movable ring 214 is always inserted into the second rotary groove 103, so that the working rod 1 rotates until the first rotary groove 216 is aligned with the second rotary groove 103.
It will be readily appreciated that a sensor for detecting whether the first rotating groove 216 is aligned with the second rotating groove 103 is provided in the case 201, and the sensor is electrically connected to the third driver 217, and before the work bar 1 rotates, whether the first rotating groove 216 is aligned with the second rotating groove 103 is detected by the sensor, thereby determining whether the third driver 217 is activated.
It is easy to understand that the transmission rod 215 on the control member 210 is provided with at least one, and generally, preferably a plurality. Correspondingly, a plurality of first rotating grooves 216 are formed in the worm gear 209, a plurality of second rotating grooves 103 are formed in the working rod 1, and the transmission rods 215, the first rotating grooves 216 and the second rotating grooves 103 are arranged in a one-to-one correspondence.
As shown in fig. 7, the work bar 1 is provided with a plurality of elevating grooves 102 which are provided at equal intervals in the axial direction, and is also provided with at least one second rotating groove 103 which extends in the axial direction and penetrates, and accordingly, the elevating grooves 102 and the second rotating groove 103 are offset from each other.
Further, it is preferable that an additional rod for increasing the depth of the working rod 1 into the pile hole is detachably attached to the upper end of the working rod 1. Based on this, the additional bars, i.e. the working bars 1 without the helical blades 101, are connected by any suitable existing detachable connection. It will be readily appreciated that if the pile hole depth is too deep, a plurality of additional bars may be provided, and adjacent additional bars may be detachably connected to ensure that the soil cleaning operation is completed.
In one possible implementation manner, the auxiliary module is selected from the auxiliary frame 3 or the auxiliary vehicle 4, and the auxiliary frame 3 and the auxiliary vehicle 4 are respectively provided with an additional module for lifting the driving module 2, and accordingly, when the operation rod 1 is driven to rotate by the driving module 2, the additional module drives the operation rod 1 and the driving module 2 to synchronously lift so as to enable the spiral blade 101 to be screwed into soil.
Based on the above design scheme, the auxiliary frame 3 can be selected to have any suitable frame structure, has a simple structure and lower cost, but workers need to perform auxiliary operation so that the pile hole soil cleaning operation device can complete soil cleaning operation. The auxiliary vehicle 4 has more comprehensive functions, is beneficial to realizing automatic operation, and has higher cost. Thus, the staff can choose according to the actual working condition.
In addition, for the auxiliary module driving operation rod 1 and driving module 2 to move down in the soil taking operation, it is completed by the additional module, and for the auxiliary frame 3 and the auxiliary vehicle 4, the structures of the additional module are different, specifically:
in one possible implementation, the auxiliary frame 3 comprises two oppositely disposed frames 301 and several connecting rods 302 for connecting the two frames 301;
A sliding groove with two open ends is formed between the two frames 301, and a connecting rod 302 is connected with the frames 301 and seals one end of the sliding groove;
The additional module is arranged on the frame 301 and can be suspended above the pile hole, the additional module comprises a base plate 303, a fourth driver 304, a rotating wheel 305 and a sliding block 306, the base plate 303 is fixed on the frame 301, the fourth driver 304 is arranged on the base plate 303, the output end of the fourth driver 304 is connected with the rotating wheel 305, the rotating wheel 305 is rotatably arranged on the base plate 303 and is connected with the sliding block 306 through a connecting rod 307, and the sliding block 306 is slidably arranged on the base plate 303 and is detachably connected with the driving module 2.
Based on the above design, the additional module is configured as a slider reciprocating mechanism, that is, the fourth driver 304 drives the rotating wheel 305 to rotate, the rotating wheel 305 is connected through the connecting rod 307 and drives the slider 306 to slide reciprocally, and when the slider 306 slides downwards, the working rod 1 and the driving module 2 move downwards as a whole, so that the spiral blade 101 moves downwards and cuts into the soil. Conversely, when the slider 306 moves upward, the working rod 1 and the driving module 2 move upward and return as a whole, and the two parts of soil are separated.
When the soil pouring operation is carried out, a worker pulls the driving module 2 to move towards the open end of the chute so as to stagger the spiral blade 101 from the pile hole, and the worker can clean soil on the spiral blade 101.
For the connection of the slider 306 and the driving module 2, if a first concave connecting groove is formed in the slider 306, a convex clamping strip is arranged on the box 201 of the driving module 2, one end of the first connecting groove is open, and when the clamping strip is inserted into the connecting groove from the open end of the connecting groove, the connection of the slider 306 and the driving module 2 is realized. Conversely, the sliding block 306 is separated from the driving module 2, so that the driving module 2 can move along the sliding groove and away from the pile hole, thereby facilitating soil dumping operation.
Correspondingly, the frame 301 is provided with a second connecting groove, and when the sliding block 306 moves upwards to reset, the first connecting groove is communicated with the second connecting groove so that the driving module 2 can slide along the frame 301.
In a possible implementation, the auxiliary vehicle 4 is provided with an auxiliary unit 401 and a robot arm 402, the auxiliary unit 401 being used for controlling the movement of the robot arm 402, the robot arm 402 being connected to the drive module 2, and the robot arm 402 accordingly being used as an add-on module.
Based on the above design, the auxiliary unit 401 is used for implementing functions such as control and power supply, and the auxiliary unit 401 may be formed by selecting any suitable existing device. The mechanical arm 402 has a multi-degree-of-freedom moving function so as to realize various movements, thereby realizing soil taking operation, soil dumping operation and the like and realizing automatic operation, and it is easy to understand that any suitable existing model can be selected for the mechanical arm 402.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the scope of the invention, but to limit the invention to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
