Description

Technical Field

[0001] The present invention relates to the technical field of pile drivers, in particular to an intelligent pile driver for civil engineering construction. Background Art

[0002] Pile drivers are usually required in civil engineering construction to hammer the pile into the ground. Common pile drivers include diesel hammer pile drivers, which achieve the effect of piling by repeatedly hitting the upper end of the pile column. In order to prevent the pile from deflecting when it is just driven into the ground, a guide structure is set to guide it.

[0003] According to the publication number: CN113073647A, a pile driver that is easy to operate for construction engineering relates to the technical field of construction engineering equipment. Aiming at the problem that the existing pile driver is inconvenient to operate when encountering pile columns of different sizes, the following scheme is proposed, which includes a pile driver body and a pile column, the pile column is located on one side of the pile driver body and below the pile hammer of the pile driver body, the pile frame of the pile driver body is fixedly installed with a hydraulic telescopic rod close to the side wall of the pile column, the bottom end of the hydraulic telescopic rod is fixedly installed with a support plate, and the support plate is fixedly installed with a guide ring away from the side wall of the pile driver body.

A plurality of movable grooves 47 are provided on opposite sides of the two arc-shaped clamping blocks 42, and a movable movable protrusion 48 is provided inside the movable groove 47. The surface of the movable protrusion 48 is in sliding contact with the inner wall of the movable groove 47, and a steel ball 49 is rotatably connected in the groove of the movable protrusion 48. The limiting guide mechanism 4 also includes a support plate 410, which is installed on the top of the connecting shell 41, and a baffle 411 is provided at the bottom of the support plate 410.

[0048] By means of the cooperation among the mounting plate 21, the driven gear 22, the connecting plate 23, the servo motor 24, the driving gear 25, the annular plate 26, the fixing groove 27, the rotating motor 28, the adjusting rod 29, the adjusting block 210, the movable block 211, the clamping block 212, the clamping groove 213, the positioning groove 214, the positioning block 215 and the stabilizing block 216, it is convenient to adjust the position of the arc clamping block 42 when in use. When the pile body needs to be completely driven into the ground, the arc clamping block 42 can be automatically withdrawn so that the arc clamping block 42 can be separated from the pile body to avoid affecting the pile body from being completely driven into the ground. Moreover, by means of the cooperation among the clamping block 212 and the clamping groove 213, the stability of the two gears after the rotation stops is further improved, thereby improving the stability of the arc clamping block 42 when in use.

[0049] Furthermore, a plurality of connecting rods 416 are fixedly connected to the side of the movable protrusion 48 away from the steel ball 49, and a connecting groove 417 is provided on the inner wall of the movable groove 47 and at the position corresponding to the connecting rod 416. One end of the connecting rod 416 close to the connecting groove 417 passes through the movable groove 47 and the connecting groove 417 in sequence and extends to the inside of the connecting groove 417. An extrusion spring 418 is sleeved on the surface of the connecting rod 416. Slide grooves 419 are provided on the left and right sides of the inner wall of the movable groove 47. The left and right sides of the movable protrusion 48 are fixedly connected. A slider 420 is connected to the slide groove 419 for sliding contact.

The connecting rod 416, the connecting groove 417 and the extrusion spring 418 are provided to enable the movable protrusion 48 and the steel ball 49 to move back and forth. When the surface of the pile body is not smooth, the steel ball 49 can drive the movable protrusion 48 to move, so that the steel ball 49 can fit closely to the pile body with an uneven surface, thereby improving the positioning and guiding effect of the pile body.

[0050] The movable groove 47, the movable protrusion 48 and the steel ball 49 cooperate with each other to reduce the friction between the arc clamping block 42 and the pile body, thereby preventing the pile body from being driven into the ground due to the large friction between the arc clamping block 42 and the pile body.

[0051] Through the mutual cooperation of the fixed shell 31, the movable plate 32, the electric push rod 33, the sliding block 34, the reinforcement plate 35, the support plate 410, the baffle 411, the fixed rod 412, the base 413, the second pressure sensor 414, the buffer spring 415, the connecting shell 41, the arc clamping block 42, the driving motor 43, the forward threaded rod 44, the reverse threaded rod 45 and the threaded block 46, when the lower connecting piece 73 of the cylinder moves downward for piling and comes into contact with the second pressure sensor 414, the electric push rod 33 can quickly drive the second pressure sensor 414 to move downward through the arc clamping block 42, and separate the arc clamping block 42 from the pile body, so as to automate the operation of clamping and separating the pile body by the arc clamping block 42, thereby improving the intelligent effect of the pile driver.

[0052] The top of the mounting plate 21 is fixedly connected with a stabilizing plate 5 , and the top of the stabilizing plate 5 is fixedly connected with the left side of the frame 1 through a cross plate 6 . The left side of the frame 1 is provided with a diesel hammer piling assembly 100 , and the diesel hammer piling assembly 100 is provided with a distance sensor 77 .

[0053] Through the cooperation of the first pressure sensor 220 and the distance sensor 77, the rotating motor 28 is started at the right time according to the hardness of the soil, and the driving gear 25 and the driven gear 22 are locked, thereby ensuring stability during use.

[0054] Furthermore, the diesel hammer pile driving assembly 100 includes a first guide rod 71, which is installed on the frame 1. The surfaces of the first guide rod 71 are slidably connected with a driving block 72 and a cylinder lower connecting piece 73, respectively. The bottom of the driving block 72 is fixedly connected to the top of the cylinder lower connecting piece 73 through two second guide rods 74. A cylinder upper knocking piece 75 matching with the cylinder lower connecting piece 73 is arranged above the cylinder lower connecting piece 73. The cylinder upper knocking piece 75 is slidably connected to the surfaces of the two second guide rods 74. The bottom of the cylinder lower connecting piece 73 is fixedly connected with a pile body slot 76, and a distance sensor 77 is installed on the back of the cylinder lower connecting piece 73.

[0055] Specifically, the servo motor 24 is started, and the servo motor 24 drives the driving gear 25 to rotate clockwise through the output shaft, and the driving gear 25 drives the driven gear 22 to rotate counterclockwise, so that the driven gear 22 drives the fixed shell 31 and the arc-shaped clamping block 42 to rotate rightward, so that the two arc-shaped clamping blocks 42 move to the lower side of the corresponding pile body slot 76, thereby achieving the following Figure 1In the state shown, the driven gear 22 just drives the connecting block 217 and the rubber block 218 to move close to the first pressure sensor 220. When the first pressure sensor 220 senses the pressure value and transmits the signal to the central processing unit, the central processing unit starts the rotating motor 28. The rotating motor 28 drives the adjusting rod 29 to rotate. The adjusting rod 29 drives the movable block 211 and the card block 212 to move upward through the adjusting block 210, so that the card block 212 is inserted into the card slot 213, and the positioning block 215 is inserted into the positioning slot 214, so that the driving gear 25 and the driven gear 22 can be limited and locked.

[0056] Specifically, the pile is hoisted beside the frame 1, and then the pile body is inserted into the pile body slot 76, and the pile body passes through the two arc-shaped clamping blocks 42, and then the driving motor 43 is started. The driving motor 43 drives the forward threaded rod 44 and the reverse threaded rod 45 to rotate through the output shaft, so that the two threaded blocks 46 move closer to each other, and the arc-shaped clamping block 42 moves closer to the pile body. The arc-shaped clamping block 42 clamps the pile body and positions it. Then, the external hook is used to lift the knocking piece 75 on the cylinder, and the hook is disengaged to allow the knocking piece 75 on the cylinder to fall and be sleeved on the plunger of the lower connecting piece 73 of the cylinder, so as to seal the upper part of the cylinder. The air in the knocking piece 75 is compressed, and when the knocking piece 75 on the cylinder continues to fall, the fuel pump in the lower connecting piece 73 of the cylinder sprays oil mist into the cylinder (not shown in the figure). The oil mist encounters the high-temperature gas above the ignition point and explodes. The explosive force impacts downward to make the pile sink, and at the same time pushes upward to make the knocking piece 75 on the cylinder rise. When the knocking piece 75 on the cylinder falls along the second guide rod 74 again, the second impact cycle starts again. This process will be repeated until the pile is driven to the required depth. At the same time, since the working principle of the diesel hammer pile driver is an existing public technology, it will not be elaborated on here.

[0057] Furthermore, when the hardness of the soil into which the pile body needs to be driven is detected in advance, it can be selected whether to use the rotating motor 28 and at the same time turn off the distance sensor 77. When it is detected in advance that the soil into which the pile body needs to be driven is relatively soft, the first pressure sensor 220 is turned off in advance by the central processor, so that the first pressure sensor 220 cannot sense the squeezing force exerted on it by the rubber block 218, and the rotating motor 28 cannot be started by the central processor. When it is detected in advance that the soil into which the pile body needs to be driven is relatively hard, the first pressure sensor 220 is turned on in advance so that the rubber block When 218 comes into contact with the first pressure sensor 220, the first pressure sensor 220 can sense the pressure value, thereby starting the rotating motor 28. When the soil is hard, it means that the piling time is long, and it is even more important to ensure that the pile body will not be offset during piling. At this time, the driven gear 22 will position the pile body due to the arc-shaped clamping block 42, thereby generating a certain torque on the driving gear 25. Starting the rotating motor 28 allows the block 212 to be inserted into the slot 213, thereby ensuring the self-locking of the two gears, improving the safety of the gears when in use, and avoiding damage.

[0058] Furthermore, when the hardness of the soil into which the pile body needs to be driven is not detected, the distance sensor 77 needs to be turned on and the first pressure sensor 220 needs to be turned off. When the pile body is driven into relatively soft soil, the lower connecting piece 73 of the cylinder, the pile body slot 76 and the pile body are at the same position each time they descend, and there will not be too much deviation. When the distance sensor 77 is driven downward by the lower connecting piece 73 of the cylinder, the distance between it and the ground will be reduced within approximately the same range each time (range error 5-10cm). The induced signal is transmitted to the central processor through the distance sensor 77, and the central processor can determine that the soil into which the pile body is driven is relatively soft, so there is no need to start the rotating motor 28. When the pile body is driven into soil with hard soil, the lower connecting piece 73 of the cylinder, the pile body slot 76 and the pile body are at the same position each time they descend, and there will not be too much deviation. The descending position is different each time. At the beginning, the descending position of the pile body when inserted into the ground will not change much. As it comes into contact with the hard part of the soil, the descending position of the pile body will be shortened each time. At the same time, the descending position of the distance sensor 77 will also be shortened each time. The distance sensor 77 transmits the induced signal to the central processing unit, and the central processing unit can determine that the soil into which the pile body is driven is relatively hard, and directly starts the rotating motor 28 through the central processing unit, so that the block 212 can be inserted into the card slot 213, thereby ensuring the self-locking of the two gears. When the first pressure sensor 220 is turned on, the turning on of the rotating motor 28 is judged by the first pressure sensor 220, and when the first pressure sensor 220 is turned off, the turning on of the rotating motor 28 is directly judged by the central processing unit.

[0059] Furthermore, the distance sensor 77 , the servo motor 24 , the rotary motor 28 , the first pressure sensor 220 , the electric push rod 33 , the drive motor 43 and the second pressure sensor 414 are electrically connected to the central processing unit, respectively.

[0060] When in use, the knocking piece 75 on the cylinder repeatedly moves up and down to hammer the lower connecting piece 73 of the cylinder, so that the lower connecting piece 73 of the cylinder drives the pile body to move downward continuously, so that the lower connecting piece 73 of the cylinder and the driving block 72 move downward continuously on the first guide rod 71, and the pile body moves downward and produces rolling contact with the steel ball 49. When the surface of the pile body is uneven, the pile body will move close to the extrusion spring 418 through the steel ball 49 and the movable protrusion 48, thereby squeezing the extrusion spring 418.

[0061] Specifically, when the cylinder lower connecting piece 73, the pile body slot 76 and the pile body gradually move downward, the cylinder lower connecting piece 73 will come into contact with the second pressure sensor 414, which means that the pile body is about to be completely inserted into the ground, and the second pressure sensor 414 squeezes the buffer spring 415 downward through the base 413 to move, and at the same time, the second pressure sensor 414 transmits the signal of the sensed pressure value to the central processing unit, and the central processing unit immediately starts the electric push rod 33 and the drive motor 43, the electric push rod 33 drives the sliding block 34 and the movable plate 32 to move downward, the movable plate 32 drives the arc clamping block 42 to move, and at the same time drives the second pressure sensor 414 to move downward and separate from the cylinder lower connecting piece 73, the drive motor 43 drives the forward threaded rod 44 and the reverse threaded rod 45 to rotate through the output shaft, so that the two threaded blocks 46 move away from each other, and the two arc clamping blocks 42 move away from each other and the pile body. The body is separated, and the central processing unit immediately starts the rotating motor 28. The rotating motor 28 drives the adjusting rod 29 to rotate through the output shaft. The adjusting rod 29 drives the movable block 211 to move downward through the adjusting block 210, and the movable block 211 drives the clamping block 212 to move downward, so that the clamping block 212 and the clamping slot 213 are separated, and the positioning slot 214 and the positioning block 215 are separated. Then the central processing unit immediately starts the servo motor 24, and the servo motor 24 drives the driving gear 25 to rotate counterclockwise through the output shaft. The driving gear 25 drives the driven gear 22 to rotate clockwise, and the driven gear 22 drives the fixed shell 31 and the arc clamping block 42 to rotate left, so that the arc clamping block 42 rotates 60 degrees or 90 degrees to the left, so that the arc clamping block 42 cannot affect the lower connecting piece 73 of the cylinder, the pile body slot 76 and the pile body continue to move downward, so that the pile body can be completely driven into the ground.
