[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A directional pulling device for a pile driver used in construction, comprising an adjustable pulling assembly for pulling the end of a pile pipe:

[0009] The adjustable pulling assembly is fixedly installed on one side of the top of the static pile driver;

[0010] The adjustable pulling assembly includes an adjustable support frame, a pulling assembly and a self-opening clamping assembly. The adjustable support frame and the pulling assembly are installed on one side of the top of the static pile driver. The adjustable support frame whose top height can be adjusted according to the usage scenario and the pulling assembly used to pull the self-opening clamping assembly to move are both installed on one side of the top of the static pile driver, and the adjustable support frame and the pulling assembly are connected. The movable end of the pulling assembly is connected with the self-opening clamping assembly, and the self-opening clamping assembly is sleeved with the pile pipe. When the self-opening clamping assembly is subjected to force, the self-opening clamping assembly is clamped and connected with the pile pipe. When the self-opening clamping assembly is not subjected to force, the pile pipe can slide along the self-opening clamping assembly.

[0011] The bottom side wall of the static pile driver is connected with a rotating support assembly for rotating support and vertical guidance of the pile pipe. The rotating support assembly and the adjustable pulling assembly are respectively connected to the front and rear sides of the static pile driver. When the rotating support assembly is at the lowest point, the rotating support assembly is in a horizontal state.

[0014] Furthermore, the pulling assembly includes a steel rope, an anti-slip fixed pulley and a winch. The anti-slip fixed pulley is fixedly connected to the middle end of the top of the cross plate. The winch is fixedly installed on the rear side of the top of the top plate of the static pressure pile driver, and the winch is located between the sleeves. The driving end of the winch is connected to the steel rope, and the end of the steel rope away from the winch is fixedly connected to the self-opening clamping assembly along the anti-slip fixed pulley.

[0015] Furthermore, the driving end of the winch can rotate after the winch is powered off.

[0016] Furthermore, the self-opening clamping assembly includes a cloth belt, a connecting block, a spring and a slip ring. The end of the steel rope away from the winch is fixedly connected to the connecting block, the end of the connecting block away from the steel rope is fixedly connected to the cloth belt and the spring, the end of the spring away from the connecting block is fixedly connected to the slip ring, the slip ring is slidably connected to the cloth belt through the opened sliding hole, and the end of the cloth belt away from the connecting block is fixedly connected to the slip ring.

The upper end of the second rotating connecting seat is rotatably connected to the L-shaped plate, and the end of the L-shaped plate away from the second rotating connecting seat is fixedly connected to the annular plate. When the L-shaped plate is in contact with the horizontal support block, the opening of the annular plate is in a horizontal state.

[0018] Furthermore, when the annular plate opening is in a vertical state, the bottom of the annular plate is flush with the bottom of the top plate of the static pile driver, and the L-shaped plate is located outside the movable track of the lifting platform of the static pile driver.

[0019] Furthermore, the vertical limit assembly includes a first rotating connection seat, a rotating plate and a slot. The left end of the top inner wall of the static pile driver is fixedly connected to the first rotating connection seat, the first rotating connection seat is rotatably connected to the rotating plate, and a slot for use with the rotating plate is opened on the L-shaped plate.

The winch tightens the cloth belt through the anti-slip fixed pulley, and the connecting block is stretched. Under the action of the anti-slip fixed pulley, the cloth belt drives the pile pipe to rotate along the top of the installed pile pipe. After the cloth belt drives the bottom of the pile pipe connected by the cloth belt to contact the top of the installed pile pipe, it is convenient to load the pile pipe to a vertical state; then the winch is powered off, and the restoring force of the connecting block drives the slip ring to move along the cloth belt toward the spring.

When the adjustable support frame is in any active state, the pile pipe can move along the self-opening clamping component, which is convenient for loading the pile pipe to a vertical state, is conducive to alignment between pile pipes, and can avoid deflection of the pile pipe when it rotates. It is especially suitable for environments where cranes cannot be used. At the same time, the pile pipe is vertically limited, which is conducive to the vertical piling of the pile pipe.

When the self-opening clamping component 23 is subjected to force, the self-opening clamping component 23 is clamped and connected with the pile pipe. When the self-opening clamping component 23 is not subjected to force, the pile pipe can slide along the self-opening clamping component 23.

[0044] The bottom side wall of the static pile driver 1 is connected with a rotating support assembly 4 for rotating support and vertical guidance of the pile pipe. The rotating support assembly 4 and the adjustable pulling assembly 2 are respectively connected to the front and rear sides of the static pile driver 1. When the rotating support assembly 4 is at the lowest point, the rotating support assembly 4 is in a horizontal state.

The adjustable support frame 21 is in any active state, and the pile pipe can move along the self-opening clamping component 23, which is convenient for loading the pile pipe to a vertical state, which is beneficial to the alignment between the pile pipes and can avoid deflection of the pile pipe when it rotates. It is particularly suitable for environments where cranes cannot be used. At the same time, the pile pipe is vertically limited, which is beneficial to the vertical piling of the pile pipe.

[0047] Example 2: Please refer to Figure 1-Figure 10The adjustable support frame 21 includes a horizontal plate 211, a sliding rod 212, a locking pin 213, a sleeve 214, a socket 215 and a positioning hole 216. The sleeve 214 is symmetrically fixedly installed on the left and right ends of the rear side of the top plate of the static pile driver 1. The sleeve 214 is provided with positioning holes 216 at equal intervals. The sliding rod 212 is fitted and slidably connected in the sleeve 214. The lower end of the sliding rod 212 is provided with a socket 215. The positioning hole 216 aligned with the locking pin 213 and the socket 215 is plugged into the socket 215. The horizontal plate 211 is fixedly connected between the top of the sliding rod 212, and the pulling component 22 is connected to the horizontal plate 211.

[0048] The pulling assembly 22 includes a steel rope 221, an anti-slip fixed pulley 222 and a winch 223. The anti-slip fixed pulley 222 is fixedly connected to the middle end of the top of the cross plate 211. The winch 223 is fixedly installed on the rear side of the top of the top plate of the static pile driver 1, and the winch 223 is located between the sleeves 214. The driving end of the winch 223 is connected to the steel rope 221, and the end of the steel rope 221 away from the winch 223 is fixedly connected to the self-opening clamping assembly 23 along the anti-slip fixed pulley 222.

[0049] After the hoist 223 is powered off, the driving end of the hoist 223 can rotate;

[0050] The self-opening clamping assembly 23 includes a cloth belt 231, a connecting block 232, a spring 233 and a slip ring 234. The end of the steel rope 221 away from the winch 223 is fixedly connected to the connecting block 232, the end of the connecting block 232 away from the steel rope 221 is fixedly connected to the cloth belt 231 and the spring 233, the end of the spring 233 away from the connecting block 232 is fixedly connected to the slip ring 234, the slip ring 234 is slidably connected to the cloth belt 231 through the opened sliding hole, and the end of the cloth belt 231 away from the connecting block 232 is fixedly connected to the slip ring 234.

[0051] According to the height of the pile pipe, the locking pin 213 of the adjustable support frame 21 of the adjustable pulling assembly 2 is taken out from the socket 215, and the slide rod 212 is slid. The slide rod 212 drives the cross plate 211 to move. When the top height of the cross plate 211 is suitable for the height of the pile pipe, the locking pin 213 is inserted into the positioning hole 216 aligned with the socket 215 and the socket 215, and the slide rod 212 is locked in the sleeve 214, so that the adjustable pulling assembly 2 can be used for pile pipes of different heights.

[0052] The pile pipe is inserted into the vertical limiting assembly 3, and then the cloth belt 231 is sleeved on the pile pipe, and the winch 223 tightens the cloth belt 231 through the anti-slip fixed pulley 222, and the connecting block 232 is stretched. Under the action of the anti-slip fixed pulley 222, the cloth belt 231 drives the pile pipe to rotate along the top of the installed pile pipe. After the cloth belt 231 drives the bottom of the pile pipe connected with the cloth belt 231 to contact the top of the pile pipe after installation, it is convenient to feed the pile pipe to a vertical state, which is conducive to the alignment between the pile pipes; then the winch 223 is powered off, and the restoring force of the connecting block 232 drives the slip ring 234 to move along the cloth belt 231 toward the spring 233, and the cloth belt 231 is in an active contact state with the pile pipe, and there is no need to manually operate the cloth belt 231 from the pile pipe.

[0053] Example 3: Please refer to Figure 1 , Figure 4 , Figure 5 and Fig.10 The rotating support assembly 4 includes an L-shaped plate 41, an annular plate 42, a horizontal support block 43 and a second rotating connection seat 44. The second rotating connection seat 44 is fixedly connected to the front side of the bottom of the static pile driver 1. The horizontal support block 43 is fixedly connected to the side wall of the second rotating connection seat 44 away from the static pile driver 1. The upper end of the second rotating connection seat 44 is rotatably connected to the L-shaped plate 41. The end of the L-shaped plate 41 away from the second rotating connection seat 44 is fixedly connected to the annular plate 42. When the L-shaped plate 41 is in contact with the horizontal support block 43, the opening of the annular plate 42 is in a horizontal state.

[0054] When the opening of the annular plate 42 is in a vertical state, the bottom of the annular plate 42 is flush with the bottom of the top plate of the static pile driver 1, and the L-shaped plate 41 is located outside the movable track of the lifting platform of the static pile driver 1;

[0055] The L-shaped plate 41 of the rotating support assembly 4 rotates downward along the second rotating connecting seat 44, and the L-shaped plate 41 rotates until it is in contact with the horizontal supporting block 43, and the L-shaped plate 41 drives the annular plate 42 to be in a horizontal state, and the external driving device inserts the pile pipe into the annular plate 42, and the pile pipe contacts the exposed part of the pile pipe after installation, and then the self-opening clamping assembly 23 of the adjustable pulling assembly 2 is sleeved on the outer end of the pile pipe, and the adjustable supporting frame 21 pulls the self-opening clamping assembly 23 along the pulling assembly 22, and the self-opening clamping assembly 23 drives the pile pipe to rotate along the exposed part of the pile pipe after installation, and the annular plate 42 rotates with the rotating pile pipe, and the self-opening clamping assembly 23 drives the bottom of the pile pipe connected to the self-opening clamping assembly 23 to contact the top of the pile pipe after installation, and the annular plate 42 rotates along the second rotating connecting seat 44 to straighten the rotating pile pipe, so as to avoid shaking when the pile pipe rotates, thereby ensuring safety.

[0056] Example 4: Please refer to Figure 1 , Figure 4 , Figure 5 and Fig.10The vertical limit assembly 3 includes a first rotating connection seat 31, a rotating plate 32 and a slot 33. The left end of the top inner wall of the static pile driver 1 is fixedly connected with the first rotating connection seat 31, the first rotating connection seat 31 is rotatably connected with the rotating plate 32, and the L-shaped plate 41 is provided with a slot 33 used in conjunction with the rotating plate 32.

[0057] Before the L-shaped plate 41 rotates downward, it pushes the rotating plate 32 to rotate along the first rotating connection seat 31 , and the rotating plate 32 is separated from the slot 33 . Meanwhile, the rotating plate 32 is in contact with the top plate of the static pile driver 1 .

[0058] The L-shaped plate 41 rotates upward to a vertical state, and when the pile pipe contacts the exposed part of the installed pile pipe, the rotating plate 32 is inserted into the slot 33. The rotating plate 32 and the slot 33 cooperate to vertically limit the L-shaped plate 41, which can prevent the L-shaped plate 41 from rotating along the second rotating connecting seat 44, thereby ensuring that the pile pipe is always in a vertical state after loading.

[0059] For example 2, please refer to Figure 1-Figure 10 A method for using a directional traction device for a pile driver for construction comprises the following steps:

[0060] Step 1: Push the rotating plate 32 to rotate along the first rotating connection seat 31, the rotating plate 32 is separated from the slot 33, and at the same time, the rotating plate 32 is in contact with the top plate of the static pile driver 1, and the L-shaped plate 41 of the rotating support assembly 4 rotates downward along the second rotating connection seat 44, and the L-shaped plate 41 rotates to be in contact with the horizontal support block 43, and the L-shaped plate 41 drives the annular plate 42 to be in a horizontal state;

[0061] Step 2: According to the pile pipe height, the lock pin 213 of the adjustable support frame 21 of the adjustable pulling assembly 2 is taken out from the socket 215, and the slide bar 212 is slid. The slide bar 212 drives the cross plate 211 to move. When the top height of the cross plate 211 is suitable for the pile pipe height, the lock pin 213 is inserted into the positioning hole 216 aligned with the socket 215 and the socket 215, and the slide bar 212 is locked in the sleeve 214;

[0062] Step 3: The external driving device inserts the pile pipe into the annular plate 42, and the pile pipe contacts the exposed part of the installed pile pipe, and then the cloth belt 231 is sleeved on the pile pipe, and the winch 223 tightens the cloth belt 231 through the anti-slip fixed pulley 222, and the connecting block 232 is stretched. Under the action of the anti-slip fixed pulley 222, the cloth belt 231 drives the pile pipe to rotate along the top of the installed pile pipe, and the cloth belt 231 drives the bottom of the pile pipe connected by the cloth belt 231 to contact the top of the installed pile pipe, so that the pile pipe can be loaded to a vertical state; then the winch 223 is powered off, and the restoring force of the connecting block 232 drives the slip ring 234 to move along the cloth belt 231 toward the spring 233, and the cloth belt 231 is in an active contact state with the pile pipe, and there is no need to manually operate the cloth belt 231 from the pile pipe;

[0063] Step 4: Rotate the rotating plate 32 and insert it into the slot 33 . The rotating plate 32 and the slot 33 cooperate to vertically limit the L-shaped plate 41 , thereby preventing the L-shaped plate 41 from rotating along the second rotating connection seat 44 .
