Description

Technical Field

[0001] This application relates to the field of pile driving machines, and in particular to a static pile driving device for precast pipe piles penetrating gravel layers. Background Technology

[0002] During construction, a foundation needs to be established, and concrete piles are driven into the ground to compact the soil, thereby reinforcing the foundation. These piles are typically prefabricated reinforced concrete piles manufactured in factories or on-site, usually with solid square or conical cross-sections. Centrifugal methods can be used to create hollow circular cross-sections (pipe piles). Methods for driving concrete piles into the ground include hammer driving, vibration driving, pressing, and static pile driving.

[0003] Existing as Figure 1 The demonstration shows a static pile driving device for precast pipe piles penetrating gravel layers, including a vehicle body 2, an operating seat 3, and a hoisting device 4. The hoisting device 4 is installed on the vehicle body 2 and transports the concrete pile 1 to the operating seat 3. A clamping device 6 is also installed inside the operating seat 3. A stabilizing device 5 is also installed inside the vehicle body 2. The stabilizing device 5 fixes the vehicle body 2 to the ground. The clamping device 6 can clamp the concrete pile 1 and drive the concrete pile 1 to be inserted into the ground, thereby completing the erection of the concrete pile 1.

[0004] Because the concrete pile 1 is inserted into the ground by the clamping device 6, the ground will cause a relatively large obstacle to the concrete pile 1 during the initial insertion process, which may damage the concrete pile 1. In addition, the concrete pile 1 will be difficult to insert into the ground during the insertion process. Summary of the Invention

[0005] To facilitate the insertion of concrete piles into the ground, this application provides a static pile driving device for precast pipe piles to penetrate gravel layers.

[0006] This application provides a static pile driving device for precast pipe piles penetrating gravel layers, employing the following technical solution:

[0007] A static pile driving device for precast pipe piles penetrating gravel layers includes a vehicle body, a clamping mechanism, and an insertion mechanism. The clamping mechanism includes several clamping rings disposed on the outer periphery of the concrete pile, a control component for controlling the sliding of the clamping rings toward or away from the concrete pile, and a lifting component for controlling the lifting and lowering of the clamping mechanism. The insertion mechanism includes several insertion rods movable on the lifting seat. The insertion mechanism has a first use state and a second use state. The vehicle body is provided with a mounting seat, and the mounting seat is provided with an adjustment component for controlling the insertion mechanism to change from the first use state to the second use state when the insertion mechanism rises for the first time.

[0008] The mounting base is provided with a drilling assembly that controls the vertical sliding and rotation of the plug rod when the plugging mechanism is in the first use state and the clamping ring slides vertically. The mounting base is also provided with a filling assembly that causes the plug rod to fill the soil toward the concrete pile when the plugging mechanism is in the second use state and the clamping ring slides vertically.

[0009] By adopting the above technical solution, the insertion mechanism is placed in the first use state. Then, a concrete pile is installed on the mounting base, and several insertion rods are located on the outer periphery of the concrete pile. The clamping ring is then controlled by the control component to clamp the concrete pile, and the clamping ring is lowered by the lifting component. Under the action of the drilling component, the insertion rods begin to rotate, loosening the ground around the concrete pile. At this time, the concrete pile can be smoothly inserted into the ground. Then, the lifting component drives the clamping ring to rise. At this time, under the action of the adjusting component, the insertion mechanism changes to the second use state. The lifting base lowers the concrete pile again. At this time, under the action of the filling component, the insertion rods fill the soil towards the concrete pile, filling back the excess pit dug by the insertion rods, thus facilitating the insertion of the concrete pile into the ground.

[0010] Optionally, the clamping mechanism further includes a lifting seat, and the control component is a control hydraulic cylinder. The control hydraulic cylinder includes a control cylinder body and a control piston rod. The control cylinder body is mounted on the lifting seat, and the side of the control piston rod away from the control cylinder body is located on the side of the clamping ring away from the concrete pile.

[0011] By adopting the above technical solution, the hydraulic cylinder is activated, and under the action of the piston rod, the clamping ring slides towards or away from the concrete pile.

[0012] Optionally, the lifting assembly includes a lifting motor and a lifting screw, wherein the output shaft of the lifting motor is disposed together with the lifting screw, and the lifting screw is threadedly connected to the lifting base.

[0013] By adopting the above technical solution, the lifting motor is started, and the lifting screw is rotated by the lifting motor. Since the lifting screw is threadedly connected to the lifting seat, the lifting assembly drives the lifting seat to slide vertically.

[0014] Optionally, the adjusting assembly includes a push rod and an abutment block. The push rod is mounted on the mounting base. The abutment block has a guide slope for the push rod to abut against and control the sliding of the abutment block away from the concrete pile. The abutment block is provided with a guide block. The lifting base has a first guide groove and a second guide groove for the guide block to slide. When the insertion mechanism is in the first use state, the guide block slides in the first guide groove. When the insertion mechanism is in the second use state, the guide block slides in the second guide groove. A third guide groove connects the first guide groove and the second guide groove. During the sliding of the abutment block away from the concrete pile, the guide block slides in the third guide groove.

[0015] By adopting the above technical solution, when the plug-in mechanism is in the first use state, the guide block slides in the first guide groove. When the push rod is under the action of the guide inclined surface, the push rod pushes the abutment block to gradually change the plug-in mechanism from the first use state to the second use state. The guide block enters the third guide groove. When the plug-in mechanism changes to the second use state, the guide block enters the second guide groove. The guide block can adjust the movement path of the plug-in rod and reduce the possibility of unnecessary shaking of the plug-in rod.

[0016] Optionally, the drilling assembly includes a rotating ring and several locking blocks disposed on the outer periphery of the rotating ring. The insertion rod has a locking groove on the side near the concrete pile for the locking blocks to be inserted into. The lifting seat is provided with a first rotating component for controlling the rotation of the rotating ring.

[0017] By adopting the above technical solution, when the plug-in mechanism is in the first use state, the snap-fit ​​block is snapped into the snap-fit ​​groove, and the control ring is driven to rotate by the first rotating component. At this time, with the cooperation of the snap-fit ​​block and the snap-fit ​​groove, the plug-in rod can rotate. Since the plug-in rod is installed on the lifting seat, the plug-in rod can also move vertically with the lifting seat.

[0018] Optionally, the crater filling assembly includes a rotating shaft mounted on the plug rod and a control shaft rotatably connected to the lifting seat. The lifting seat is provided with a second rotating component that controls the rotation of the control shaft. The mounting base is also provided with a connecting assembly that controls the connection between the rotating shaft and the control shaft when the plug-in mechanism changes from a first use state to a second use state.

[0019] By adopting the above technical solution, when the plug-in mechanism changes from the first use state to the second use state, under the action of the connecting component, the rotating shaft and the control shaft are connected together, and the second rotating component is activated. The rotating shaft can drive the plug-in rod to rotate, thereby achieving the effect that when the plug-in mechanism changes to the second use state, the plug-in rod can rotate, and the soil brought out of the ground by the plug-in rod will be refilled.

[0020] Optionally, the control shaft has a rotating groove for the rotating shaft to be inserted, and the groove wall of the rotating groove has a connecting groove for the rotating shaft to slide. The connecting assembly includes a connecting block and a connecting spring. The groove wall of the connecting groove has a sliding groove for the connecting block to slide. The sliding direction of the connecting block is perpendicular to the sliding direction of the rotating shaft. One end of the connecting spring abuts against the connecting block, and the other end of the connecting spring abuts against the bottom of the sliding groove. The side of the connecting block away from the rotating groove has a guide surface for the rotating shaft to abut against and control the connecting block to slide towards the bottom of the sliding groove.

[0021] By adopting the above technical solution, when the plug-in mechanism changes from the first use state to the second use state, the rotating shaft slides towards the direction of the rotating groove. Under the action of the guide surface, the connecting block is retracted into the sliding groove. After the rotating shaft enters the rotating groove, under the action of the connecting spring, the connecting block enters the connecting groove. The connecting block restricts the rotating shaft in the rotating groove, realizing the connection component controlling the connection between the rotating shaft and the control shaft. At this time, the rotation of the control shaft can drive the rotating shaft to rotate.

[0022] Optionally, the plug-in rod includes a fixed part and a sliding part located at the lower end of the fixed part. The sliding part slides on the fixed part along the length direction of the fixed part. The fixed part is provided with an elastic element that controls the sliding part to slide away from the fixed part. A stabilizing rod slides on the fixed part. The sliding part is provided with a stabilizing groove for the stabilizing rod to be inserted. The sliding direction of the stabilizing rod is perpendicular to the sliding direction of the sliding part. The mounting base is provided with an unlocking element that controls the stabilizing rod to disengage from the stabilizing groove when the plug-in mechanism rises for the first time.

[0023] By adopting the above technical solution, when the insertion mechanism is in the first use state, the sliding part is fixedly connected to the fixed part by the stabilizing rod. At this time, when the insertion rod rotates, the sliding part can loosen the soil around the concrete pile. When the insertion mechanism rises for the first time, under the action of the unlocking part, the control rod disengages from the stabilizing groove. At this time, under the action of the elastic element, the sliding part always tends to slide away from the fixed part. During the process of the insertion rod filling the soil towards the concrete pile, the sliding part always abuts against the ground, improving the filling efficiency.

[0024] Optionally, the elastic element is an abutment spring, and the fixing part is provided with a sliding groove for the sliding part to slide. One end of the abutment spring abuts against the sliding part, and the other end of the abutment spring abuts against the bottom of the sliding groove.

[0025] By adopting the above technical solution, under the action of the spring force, the sliding part always tends to slide away from the fixed part until the sliding part touches the ground.

[0026] Optionally, the unlocking component is an unlocking rod mounted on the mounting base, and the stabilizing rod is provided with a guide surface for the unlocking rod to abut against and control the stabilizing rod to slide away from the stabilizing groove.

[0027] By adopting the above technical solution, when the plug rod rises, the unlocking rod can abut against the guide surface of the stabilizing rod. At this time, under the action of the guide surface, the stabilizing rod disengages from the fixing groove, thus releasing the fixed connection between the fixing part and the sliding part.

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

[0029] When the clamping mechanism first lowers the concrete pile, the insertion rod can rotate while descending, loosening the soil around the concrete pile. Then, the clamping mechanism rises, and under the action of the adjusting component, the insertion mechanism enters its second operating state. When the lifting component lowers the insertion mechanism, the insertion rod can rotate towards or away from the concrete pile, filling the soil towards the concrete pile and filling back the excess pit dug by the insertion rod, thus facilitating the insertion of the concrete pile into the ground.

The control shaft 172 can drive the rotating shaft 171 to rotate.

[0060] Reference Figure 3An inclined guide surface 1018 is provided on the side of the sliding part 1013 away from the concrete pile 1. When the inclined guide surface 1018 abuts against the soil, the sliding part 1013 can move towards the fixed part 1012, over the soil, and then under the action of the elastic force of the abutment spring 151, the sliding part 1013 abuts against the ground. When the abutment rod rotates towards the concrete pile 1, the sliding part 1013 pushes the soil into the pit.

[0061] The implementation principle of a static pile driving device for precast pipe piles penetrating gravel layers according to an embodiment of this application is as follows:

[0062] When the abutment mechanism is placed in the first operating state, under the action of the control hydraulic cylinder 731, the clamping ring 72 can press the concrete pile 1 firmly. Then, the lifting motor 741 drives the lifting seat 71 to descend, and at the same time, the first rotating motor 131 is started. The abutment rod rotates and descends at the same time. The abutment rod loosens the soil on the outer periphery of the concrete pile 1, so as to facilitate the insertion of the concrete pile 1 into the ground.

[0063] Then, the lifting motor 741 drives the lifting seat 71 to rise. At this time, the push rod 161 pushes the abutment block 162, so that the abutment mechanism is in the second use state. At the same time, the unlocking rod 141 controls the stabilizing rod 12 to disengage from the fixed groove. The rotating shaft 171 is fixedly connected to the control shaft 172. Then, the lifting motor 741 drives the lifting seat 71 to fall. At the same time, the second rotating motor 181 drives the rotating shaft 171 to rotate. The abutment rod fills the soil towards the concrete pile 1, filling back the excess pit dug by the insertion rod 101.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
