Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a self-propelled traction-driven pile driver. Background Art

[0002] In construction, in order to prevent the building foundation from settling, it is often necessary to drive the pile pipe into the underground soil layer using a pile driver. A pile driver is a main machine that drives the pile pipe into the soil by impacting the pile pipe with a hammer. Among them, the hammers mainly include drop hammers, steam hammers, diesel hammers, and hydraulic hammers.

[0003] The drop hammer has a simple structure and is easy to use, but its production efficiency is low and the pile pipe is easily damaged; the diesel hammer has a simple structure and is easy to use. It does not require external energy supply and is the most widely used, but it will cause public hazards such as noise and air pollution, and is strictly restricted in urban construction; the steam hammer uses steam power to hammer, has a large impact force, is suitable for various piles, and has high work efficiency, but requires a set of boiler equipment; the hydraulic hammer does not emit any exhaust gas, has no noise, and has a high impact frequency.

[0041] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein in practice, so the present invention can make many similar improvements without being limited by the specific embodiments disclosed below. Without violating the connotation of the present invention, these improvements still belong to the protection scope required by the present invention.

[0042] Example 1: Please refer to Figure 1 A traction-driven pile driver provided in one embodiment of the present invention comprises a main pile frame 1, a traction mechanism, a hammer-removing device and a hammer 207. The main pile frame 1 is provided with a first pile chamber and a second pile chamber which are separated longitudinally. The traction mechanism comprises a traction wheel 201, a pulley block 202, a traction rope 206 and a traction counterweight 204. The traction counterweight 204 is arranged in the second pile chamber and is slidably connected to the side of the second pile chamber. The traction wheel 201 is installed on the top of the main pile frame 1, the traction rope 206 is wound around the traction wheel 201 and the pulley block 202, and one end of the traction rope 206 is connected to the traction counterweight 204. The hammer 207 and the hammer-removing device are arranged in the first pile chamber and are slidably connected to the side of the first pile chamber. The other end of the traction rope 206 is connected to the hammer-removing device, and the hammer 207 is arranged below the hammer-removing device. The hammer 207 can be connected to or disconnected from the hammer-removing device.

[0043] Optionally, for the convenience of maintenance, the traction wheel 201 can also be installed at the bottom of the main pile frame 1 (not shown in the figure).

[0044] The above-mentioned traction-driven pile driver includes three processes of lifting the hammer, removing the hammer and hitting the pile in coordination with each other. In the process of lifting the hammer, the hammer body 207 and the hammer removing device move upward along the side of the first pile chamber under the traction of the traction rope 206 until they move to a suitable height, so that the hammer body 207 and the pile pipe 106 maintain a preset height difference; at the same time, the traction counterweight 204 moves in the opposite direction along the side of the second pile chamber and descends to a suitable position. In the process of removing the hammer and hitting the pile, after the hammer body 207 moves to a preset height, under the action of the hammer removing device, the hammer body 207 is separated from the hammer removing device and falls rapidly under the action of its own gravity to hit the pile pipe 106, causing the pile pipe 106 to sink; in the process of the hammer body 207 falling off and hitting the pile, the hammer removing device also falls rapidly. After the hammer body 207 completes the pile driving action, the hammer body 207 is connected to the hammer release device, and the hammer body 207 and the hammer release device are lifted to a suitable height under the drive of the traction machine; at the same time, the traction counterweight 204 moves in the opposite direction and descends to a preset position. After the hammer lifting action is completed, the above-mentioned hammer release and pile driving actions are repeated until the pile pipe 106 is driven into the ground. In this way, the use of the traction counterweight 204 to balance the weight of the hammer body 207 can reduce the energy consumption of the hammer lifting, increase the weight of the hammer body 207, and thus increase the pile driving energy of the hammer body 207. During the pile driving process, the hammer body 207 is separated from the constraint of the traction counterweight 204 by the hammer release device, which can increase the potential energy of the hammer body 207, thereby increasing the pile driving energy. In addition, the traction-driven pile driver saves energy, has low noise, and has the effects of energy saving and environmental protection, so that it can replace the existing steam hammer, diesel hammer, hydraulic hammer and other pile driving equipment, and is widely used in urban and rural construction. In addition, the traction mechanism has a simple structure and there are ready-made spare parts in the market. It is installed in conjunction with the steel structure main pile frame 1, so that the overall weight is light and the production cost is low.

[0045] In one embodiment, see Figure 2The main pile frame 1 includes four columns A11, two middle columns A12, two or more long beams A13, two or more side beams A14, two or more middle beams A15 and two or more short beams A16. The four columns A11 are symmetrically erected at the four corners of the main pile frame 1. On the left side or right side of the main pile frame 1, two columns A11 are longitudinally connected by two or more side beams A14. At the front and rear sides of the main pile frame 1, the upper and lower parts of the two columns A11 are horizontally connected by a long beam A13, and the two ends of the two middle columns A12 are erected in the middle of the long beam A13. The two middle columns A12 are horizontally connected to the left and right adjacent columns A11 by two or more short beams A16, and the middle columns A12 are longitudinally connected by two or more middle beams A15; or, at the front and rear sides of the main pile frame 1, two middle columns A12 are symmetrically arranged between the two columns A11, and the two middle columns A12 are horizontally connected to the left and right adjacent columns A11 by two or more short beams A16, and the middle columns A12 are longitudinally connected by two or more middle beams A15. The middle beam A15 divides the main pile frame 1 and encloses and forms the first pile chamber and the second pile chamber. In this way, the main pile frame 1 with the first pile chamber and the second pile chamber is obtained, and the main pile frame 1 has a strong ability to resist side winds.

[0046] Optionally, the above-mentioned columns A11, center columns A12, long beams A13, side beams A14, center beams A15 and short beams A16 are steel pipes, and the steel pipes are connected in the above-mentioned manner to obtain the main pile frame 1 having the first pile chamber and the second pile chamber. Of course, in other embodiments, the main pile frame 1 can also be a pipe body having the first pile chamber and the second pile chamber, for example, the main pile frame 1 is obtained by welding steel plates.

[0047] Further, see Figure 1 and Figure 2 The traction driven pile driver also includes at least two guide rails A101 and at least two guide rails B102. The guide rails A101 are fixedly mounted relatively and vertically on the side beams A14 and the middle beam A15 of the first pile chamber; or, the guide rails A101 are fixedly mounted relatively and vertically on the side beams A14 and the middle beam A15 of the first pile chamber via guide rail brackets 103. The guide rails B102 are fixedly mounted relatively and vertically on the side beams A14 and the middle beam A15 of the second pile chamber; or, the guide rails B102 are fixedly mounted relatively and vertically on the side beams A14 and the middle beam A15 of the second pile chamber via guide rail brackets 103. The hammer body 207 and the hammer release device are slidably connected to the guide rail A101, respectively, and the traction counterweight 204 is slidably connected to the guide rail B102 via the counterweight carriage 205. In this way, the guide rail A101 and the guide rail B102 can play a guiding role to ensure that the hammer 207 and the traction counterweight 204 are lifted and lowered smoothly in the vertical direction.

[0048] It should be noted that, see Figure 2 The number of guide rails A101 and guide rails B102 can be set according to actual needs, and the number of guide rails A101 and guide rails B102 is not limited here.

[0049] In one embodiment, see Figure 1 , Figure 4 and Figure 5 , the hammer-off device is an electromagnetic hammer-off device. Specifically, the electromagnetic hammer-off device includes a hanger 212 and an electromagnet 216 connected to a power source, the electromagnet 216 is insulated and connected to the hanger 212, the hanger 212 is slidably connected to the side of the first pile chamber, and one end of the traction rope 206 is connected to the hanger 212. The traction-driven pile driver also includes a hammer slide 208, a hammer 207 is arranged on the hammer slide 208 and is slidably connected to the side of the first pile chamber through the hammer slide 208, and the hammer 207 is electromagnetically matched with the electromagnet 216. Specifically, the hanger 212 and the hammer slide 208 are respectively slidably connected to the guide rail A101, the electromagnet 216 is slidably connected to the guide rail A101 through the hanger 212, and the hammer 207 is slidably connected to the guide rail A101 through the hammer slide 208.

[0050] When using the electromagnetic hammer-off device, during the process of lifting the hammer, the electromagnet 216 is powered on and attracts the hammer body 207. The hammer body 207 and the electromagnet 216 move upward under the traction of the traction rope 206 until they reach a preset height. After the hammer body 207 reaches the preset height, the power supply of the electromagnet 216 is cut off, so that the hammer body 207 is freed from the constraint of the electromagnet 216, so that the hammer body 207 falls rapidly under the action of its own gravity and hits the pile pipe 106, causing the pile pipe 106 to sink. During the process of the hammer body 207 falling off and hitting the pile, the hammer-off device also falls rapidly. When the hammer body 207 completes the pile hitting action, the above-mentioned hammer-off, hammer-off and pile hitting actions are repeated again until the pile pipe 106 is driven into the ground. During the process of lifting the hammer, hammer-off and pile hitting, the traction counterweight 204 moves in the second pile chamber in the opposite direction.

[0051] Of course, in other embodiments, the hammer-off device may also be a mechanical hammer-off device. Fig.11 and Fig.12The mechanical hammer-off device further comprises a hook 211, a hanger 212, a hanger cross tube 213, an elastic member 214 and a stop frame 220. The hanger 212 is slidably connected to the side of the first pile chamber, the hanger cross tube 213 is fixedly arranged on the hanger 212, and the hanger cross tube 213 and the hanger 212 are suspended in the first pile chamber through the traction rope 206. The hook 211 is movably arranged on the hanger cross tube 213, and the hook 211 is used to hook the hammer 207. One end of the elastic member 214 is connected to the hook 211, and the other end is connected to the hanger 212. The stop frame 220 is arranged above the hook 211. When the hook 211 contacts the stop frame 220, the hook 211 rotates to separate the hook 211 from the hammer 207. Furthermore, the mechanical hammer-releasing device further comprises a reinforcing plate 215 , and the reinforcing plate 215 is arranged on the hook 211 , thereby effectively preventing the hook 211 from being deformed.

[0052] When the mechanical hammer-off device is used, during the process of lifting the hammer, the hook 211 hooks the hammer 207, and under the drive of the traction machine and the traction of the traction rope 206, the hammer 207 is lifted to a suitable height, so that the hammer 207 and the pile pipe 106 maintain a preset height difference. After the hammer 207 is lifted to a certain height, the hook 211 abuts against the stop frame 220. Since the hook 211 is movably arranged on the hanger cross pipe 213, under the action of the stop frame 220, the hook 211 rotates and disengages from the hammer 207, thereby realizing the hammer-off action. After the hammer is off, under the action of the elastic member 214, the hook 211 rotates in the opposite direction and returns to its original state, so that after the hammer 207 completes the pile-driving action, the hook 211 can hook the hammer 207 again, and drive the hammer 207 to move to a suitable height, thereby completing the hammer-off action again.

[0053] Optionally, the elastic member 214 is a spring; or, the elastic member 214 is an elastic steel plate. Of course, in other embodiments, the elastic member 214 may also be other components with the same function.

[0054] It should be noted that the balancing force on the traction counterweight 204 is very different before and after the hammer is removed. After the hammer is removed, the weight of the hanger 212 and the electromagnet 216 is relatively small. When the hammer is lowered, it is necessary to increase the wrap angle between the traction rope 206 and the traction wheel 201 to prevent the traction force from being insufficient and causing the traction rope 206 and the traction wheel 201 to slip. There are two ways to increase the wrap angle: one is to Figure 1 As shown, the two pulleys 209 and the traction wheel 201 are arranged in a straight line or an inverted triangle, and the existing traction wheel is improved to a drum-type traction wheel.

[0055] In one embodiment, Fig.10As shown, the traction mechanism further includes a traction motor 221, a spline 222, a protrusion 223 and a traction frame 224. The traction sheave 201 is connected to the traction motor 221 through the spline 222. The traction sheave 201 is provided with a spiral rope groove adapted to the traction rope 206, and the protrusion 223 is fixed to the traction frame 224 and cooperates with the spiral rope groove on the traction sheave 201. It can be understood that the traction sheave 201 is connected to the traction motor 221 through the spline 222, so that the traction sheave 201 can rotate with the traction motor 221 and can also slide on the spline 222. In this way, the traction rope 206 is wound around the rope groove of the traction wheel 201. When the traction motor 221 rotates, the traction motor 221 drives the traction wheel 201 to rotate together. The traction wheel 201 slides to the left or right under the action of the protrusion 223. This ensures that both ends of the traction rope 206 are always in a hanging state with the traction counterweight 204 and the hanger 212, thereby reducing the wear of the traction rope 206 and extending its service life.

[0056] In one embodiment, see Figure 1 and Figure 3 The traction driven pile driver also includes a controller, a counterweight sensor 218 and a magnetic stripe 219. The magnetic stripe 219 is arranged on the side of the second pile chamber. The counterweight sensor 218 is arranged on the side of the traction counterweight 204 and cooperates with the magnetic stripe 219. The counterweight sensor 218 is electrically connected to the controller, and the traction mechanism is controlled by the signal of the controller. Specifically, the magnetic stripe 219 is directly arranged on the side beam A14 of the second pile chamber; or, the magnetic stripe 219 is arranged on the side beam A14 of the second pile chamber through the guide rail bracket 103. In this way, the power on and off time of the electromagnet 216 and the lifting, releasing and pile driving strokes of the hammer 207 can be preset in the controller; in the actual working process, the controller realizes automatic control of the working process of the hammer 207 according to the position information provided by the traction counterweight 204 and the encoder. Therefore, the traction driven pile driver can adapt to different working conditions and working environments to replace pile drivers of different specifications and models, thereby realizing one machine for multiple uses.

[0057] In one embodiment, see Figure 1 and Figure 6 The traction driven pile driver further comprises a pile pipe frame 109, a fixed hoop 111 and a movable hoop 112 arranged in the first pile chamber, the pile pipe frame 109 is slidably connected to the side of the first pile chamber, the fixed hoop 111 is fixed to the pile pipe frame 109 and cooperates with the movable hoop 112 to fix the pile pipe 106. In this way, the pile pipe 106 is conveniently fixed through the cooperation of the fixed hoop 111 and the movable hoop 112, and then the pile pipe 106 is slidably connected to the first pile chamber through the pile pipe frame 109, so as to ensure that the pile pipe 106 can be smoothly sunk under the striking action of the hammer 207.

[0058] Specifically, both sides of the pile pipe frame 109 are slidably connected to the guide rail A101, that is, the pile pipe 106 is slidably connected to the guide rail A101 through the pile pipe frame 109. Since the pile pipe 106, the hammer body 207 and the hammer removal device are all installed on the same guide rail A101, the pile pipe 106 is constrained by the guide rail A101 under strong hammering energy, and vertical pile driving can be achieved, and the pile pipe 106 can be effectively prevented from being distorted and damaged.

[0059] Further, see Figure 1 and Figure 6 The traction driven pile driver further comprises an anvil 107, which is arranged on the top of the pile pipe 106. In this way, the pile pipe 106 can be protected from being damaged during the high-intensity pile driving process. Furthermore, a hammer pad is provided at the bottom of the hammer body 207, which can protect the hammer body 207 and the pile pipe 106 from being damaged during the high-intensity pile driving process.

[0060] Further, see Figure 6 The traction driven pile driver further comprises a buffer ring 113, which is used to be arranged between the pile pipe 106 and the fixed hoop 111 and the movable hoop 112. In this way, during the pile driving process, the buffer ring 113 can play a buffering role and effectively prevent the pile pipe 106 from being damaged.

[0061] In one embodiment, a hook is provided at the rear side of the main pile frame 1, and the main pile frame 1 can be hung on a crawler pile driver for separate use through the hook, so it can be called a single-hanging traction-driven pile driver. The operation of the single-hanging traction-driven pile driver can be controlled by a control element provided on the crawler pile driver, and the pile pipe guide assembly mentioned above can be omitted, and the pile pipe guide can be directly guided by the hammer slide 208 on the crawler pile driver.

[0062] Embodiment 2: This embodiment is a self-propelled traction-driven pile driver, which is improved by adding new technical solutions on the basis of embodiment 1.

[0063] See also Figure 7 and Fig. 9As shown, another embodiment of the present invention provides a self-propelled traction-driven pile driver, including a traction-driven pile driver and a bottom pile frame 2 of any embodiment in the first embodiment, wherein the bottom pile frame 2 is provided with a third pile chamber corresponding to the first pile chamber, and a fourth pile chamber corresponding to the second pile chamber, and the bottom of the main pile frame 1 is detachably connected to the top of the bottom pile frame 2. In this way, by installing the main pile frame 1 on the top of the bottom pile frame 2, the height of the main pile frame 1 can be increased to accommodate pile pipes 106 of different lengths. In addition, since the main pile frame 1 and the bottom pile frame 2 are detachably connected, processing, disassembly, transfer and transportation are convenient; and, the main pile frame 1 and the bottom pile frame 2 can be flexibly used according to different pile pipes 106, for example, the main pile frame 1 can be used alone or the main pile frame 1 and the bottom pile frame 2 can be used in combination, which is more flexible to use.

[0064] Specifically, a connecting plate 17 is provided at the bottom of the main pile frame 1, and a connecting plate 17 is correspondingly provided at the top of the bottom pile frame 2, and the connecting plates 17 of the main pile frame 1 and the bottom pile frame 2 are provided with mounting holes. By inserting mounting parts such as high-strength bolts into the mounting holes, the main pile frame 1 and the bottom pile frame 2 can be detachably connected.

[0065] It should be noted that the pile frame 2 of the large traction-driven pile driver is as high as 15 meters or more. In order to facilitate processing and transportation, the pile frame 2 may include two or more sections of the frame structure and be processed in sections. At the work site, the sections of the frame structure can be connected by bolts and other mounting parts according to the use requirements. Of course, in other embodiments, the pile frame 2 may also be an integrated frame structure.

[0066] In one embodiment, see Figure 7The bottom pile frame 2 includes a bottom cross beam 27, a bottom longitudinal beam 28, and a front cross beam 29 arranged in front of the bottom cross beam 27. The two ends of the bottom cross beam 27 and the front cross beam 29 are respectively fixedly connected to the bottom longitudinal beam 28 arranged oppositely. The bottom pile frame 2 also includes four columns B21 and two middle columns B22, as well as two or more long cross beams B23, two or more side beams B24, two middle beams B25, and two or more short cross beams B26; the four columns B21 are vertically arranged at the four corners of the bottom cross beam 27. At the left and right sides of the bottom pile frame 2, the two columns B21 are longitudinally connected by two or more side beams B24. At the rear side of the bottom pile frame 2, the tops of the two columns B21 are horizontally connected by a long cross beam B23, and the upper end of the middle column B22 is vertically connected to the middle of the long cross beam B23; or, the upper and lower parts of the two columns B21 are each horizontally connected by a long cross beam B23, and the two ends of the middle column B22 are each connected to the middle of the long cross beam B23; the middle column B22 and the left and right adjacent columns B21 are horizontally connected by two or more short cross beams B26. An opening 20 is provided at the front side of the third pile chamber, and the columns B21 at the upper part of one side of the opening 20 are connected by a long cross beam B23, and the upper end of the middle column B22 is vertically connected to the middle part of the long cross beam B23; or, the columns B21 at the upper and lower parts of the opening 20 are horizontally connected by a long cross beam B23, and the middle column B22 is arranged opposite to the middle column B22 at the rear side of the bottom pile frame 2, and its two ends are connected to the middle part of the long cross beam B23; at the front side of the fourth pile chamber, the middle column B22 is connected to the column B21 by two or more short cross beams B26; at the middle longitudinal part of the bottom pile frame 2, the middle columns B22 are longitudinally connected by two or more middle beams B25; the middle beam B25 divides the bottom pile frame 2 and is surrounded to form the third pile chamber and the fourth pile chamber. In this way, the bottom pile frame 2 has a strong ability to resist side winds.

[0067] It should be noted that, see Figure 7 Since the front side of the bottom pile frame 2 is provided with an opening 20, in order to prevent the opening 20 from being deformed during transportation, a detachable crossbeam connection or welding of a long crossbeam B23 can be used to cut off the construction site, and each section of the bottom pile frame 2 is detachably connected. In this way, processing, disassembly, transfer and transportation can be greatly facilitated.

[0068] Optionally, the bottom cross beam 27, the bottom longitudinal beam 28, the front cross beam 29, the column B21, the middle column B22, the long cross beam B23, the side beam B24, the middle beam B25 and the short cross beam B26 are steel pipes, and the steel pipes are connected in the above manner to obtain the bottom pile frame 2 with the third pile chamber and the fourth pile chamber. Of course, in other embodiments, the bottom pile frame 2 can also be a pipe body with the third pile chamber and the fourth pile chamber, for example, the bottom pile frame 2 is obtained by welding steel plates.

[0069] Further, see Figure 7 and Fig. 9The bottom pile frame 2 further includes at least two guide rails C104 and at least two guide rails D105. The guide rails C104 are fixedly arranged on the side beams B24 and the middle beams B25 of the third pile chamber relative to and vertically, and are each smoothly connected to the guide rails A101 in the first pile chamber, or the guide rails A101 extend downward from the first pile chamber to the third pile chamber to form the guide rails C104; the guide rails D105 are fixedly arranged on the side beams B24 and the middle beams B25 of the fourth pile chamber relative to and vertically, and are each smoothly connected to the guide rails B102 in the second pile chamber, or the guide rails B102 extend downward from the second pile chamber to the fourth pile chamber to form the guide rails D105. In this way, the guide rails C104 and the guide rails D105 can play a guiding role to ensure that the hammer 207 and the traction counterweight 204 are lifted and lowered smoothly in the vertical direction.

[0070] It should be noted that the number of guide rails C104 and guide rails D105 can be set according to actual needs, and the number of guide rails C104 and guide rails D105 is not limited here. Optionally, the bottom pile frame 2 also includes a guide rail bracket 103, and the guide rail C104 is relatively and respectively fixedly arranged on the side beams B24 and the middle beams B25 of the third pile chamber through the guide rail bracket 103, and each is smoothly connected with the guide rail A101 in the first pile chamber, or the guide rail A101 extends downward from the first pile chamber to the third pile chamber to form the guide rail C104; the guide rail D105 is relatively and respectively fixedly arranged on the side beams B24 and the middle beams B25 of the fourth pile chamber through the guide rail bracket 103, and each is smoothly connected with the guide rail B102 in the second pile chamber, or the guide rail B102 extends downward from the second pile chamber to the fourth pile chamber to form the guide rail D105.

[0071] In one embodiment, see Figure 3 and Fig. 9 The traction driven pile driver also includes a laser plumb measuring device 119 and a laser receiving device. The laser plumb measuring device 119 is arranged on the top of the main pile frame 1 or the bottom pile frame 2, and the laser receiving device is arranged on the bottom pile frame 2, and the laser receiving device cooperates with the projection of the laser plumb measuring device 119. In this way, by setting the laser plumb measuring device 119, it can be ensured that the main pile frame 1 and the bottom pile frame 2 are both kept vertical to the ground, so that the hammer body 207 and the traction counterweight 204 can be ensured to move vertically, so as to minimize the friction resistance and the wear of the connecting parts.

[0072] In one embodiment, see Figure 7 , Figure 8 and Fig. 9 In order to facilitate the transfer within the same construction site, the traction-driven pile driver also includes a walking mechanism. The walking mechanism includes an adjustable leg 115, a steering wheel 116 and a driving wheel 117. The adjustable leg 115, the steering wheel 116 and the driving wheel 117 are arranged on the bottom longitudinal beam 28 or the bottom cross beam 27.

[0073] Since the operation site may be uneven, the bottom pile frame 2 is provided with an adjustable leg 115, which can expand the bearing surface of the bottom pile frame 2, improve its stability, and ensure that the main pile frame 1 and the bottom pile frame 2 are vertical to the ground. High-strength bolts are provided on the adjustable leg 115. During operation, a small jack can be used to lift the bottom cross beam 27 or the bottom longitudinal beam 28 to make it out of contact with the ground, and then the high-strength nuts on each adjustable leg 115 are adjusted one by one to a suitable height until the laser plumb measuring device 119 coincides with the projection of the laser receiver, and then the high-strength nuts are locked and the jack is withdrawn.

[0074] Furthermore, a cab is provided at the bottom of the rear side of the third pile chamber, and the cab is provided with a steering wheel, an accelerator pedal and a brake pedal. A steering link is provided between the two steering wheels 116, and the steering link is connected to and controlled by the steering wheel; a motor is provided on the driving wheel 117, and the motor and the driving wheel 117 are driven by a worm gear, and the operation of the motor is controlled by the accelerator pedal and the brake pedal.

[0075] In one embodiment, see Figure 7 , Figure 8 and Fig. 9 The walking mechanism further includes a sliding platform 118 and a pile pipe pre-setting cylinder 120 disposed on the sliding platform 118. The sliding platform 118 is movably disposed at the bottom of the bottom pile frame 2. The pile pipe pre-setting cylinder 120 is used to carry the pile pipe 106. The sliding platform 118 can slide into or out of the third pile chamber from the opening 20. In this way, it is convenient to enter and replace piles.

[0076] Specifically, after the traction-driven pile driver enters the work site, it is driven to the predetermined piling location, and the midpoint of the third pile chamber is aligned with the entry point of the pile pipe 106. The sliding platform 118 is pushed out of the third pile chamber, and the pile pipe 106 is hoisted into the pre-set cylinder. After the above steps are completed, the sliding platform 118 is pushed into the third chamber together with the pile pipe 106. In this process, the pile pipe 106 enters the third pile chamber from the opening 20 at the front side of the bottom pile frame 2. The hammer body 207 and the pile pipe 106 are connected with a steel wire rope, the pile pipe 106 is hoisted, the sliding platform 118 withdraws from the third pile chamber, and the pile pipe 106 is vertically hoisted into the piling point. The pile pipe 106 is fixed by the cooperation of the fixed hoop 111 and the movable hoop 112. In this way, the pile entry can be achieved. It should be noted that the pile changing operation is the same as the pile entry operation.

[0077] To increase the traction force, as in the first embodiment, this embodiment also adopts a drum-type traction sheave 201. In this embodiment, the traction motor 221 and the traction sheave 201 can also be installed on the bottom cross beam 27 or the bottom longitudinal beam 28 in front of the fourth pile chamber (not shown in the figure), which will greatly increase the length of the traction rope 206, but facilitate the installation and maintenance of the traction machine.

[0078] The main pile frame and bottom pile frame of the self-propelled traction-driven pile driver are detachably connected and equipped with a walking mechanism, so it does not need to be used with a crawler pile driver. Therefore, it has a simple structure, is convenient for processing and transportation, has good maneuverability, and can independently perform tasks such as transfer, relocation, pile erection, and pile replacement, which can greatly reduce the cost of use and save a large amount of investment in construction projects. Crawler pile drivers are expensive, costing up to millions of yuan.

[0079] The preparation work before piling is as follows:

[0080] 1. After the pile driver enters the site, first drive it to the predetermined piling location and align the midpoint of the third pile chamber with the pile pipe entry point;

[0081] 2. Adjust each adjustable leg 115 so that the light spot of the laser plumb measuring device 119 coincides with the center point of the laser receiver; Lock each adjustable leg 115;

[0082] 3. Hang the pile pipe 106 into the pile pipe pre-setting tube 120;

[0083] 4. Push the sliding platform 118 together with the pile pipe 106 into the third pile chamber, so that the center of the pile pipe presetting cylinder 120 is aligned with the pile pipe entry point;

[0084] 5. Use a steel wire rope to connect the hammer 207 and the pile pipe 106, hang the pile pipe 106 out of the pile pipe presetting tube 120, withdraw the sliding platform 118 from the third pile chamber, and put the pile pipe 106 vertically downward into the pile point;

[0085] 6. Insert the pile pipe frame 109 together with the fixing hoop 111 and the buffer ring 113 into the pile pipe 106, and connect it to the guide rail C104 of the third pile chamber in a sliding manner, and fasten the movable hoop 112 to the fixing hoop 111 to fix the pile pipe 106;

[0086] After the above preparations are completed, piling can begin.
