[0034] Reference below Figures 1 to 7 A static pile driver according to an embodiment of the utility model is described.

[0035] like Figures 1 to 7 As shown, the static pile driver according to the embodiment of the utility model includes a frame 100 , a first walking mechanism 200 and a hydraulic system 300 .

[0036] The frame 100 is provided with a first lifting cylinder 101, and the bottom end of the first lifting cylinder 101 is connected to a pile driving mechanism 102. The pile driving mechanism 102 is a common device on a static pile driver. It can be a device for clamping prefabricated pipe piles. When the first lifting cylinder 101 drives the pile driving mechanism 102 to move downward, the prefabricated pipe piles are pressed into the ground. Alternatively, it can be a device for directly abutting the top of the prefabricated pipe piles. When the first lifting cylinder 101 drives the pile driving mechanism 102 to move downward, the prefabricated pipe piles are pressed into the ground.

[0037] The first walking mechanism 200 includes a first guide rail 201, a first sliding portion 202 and a first driving cylinder 203. The first guide rail 201 can be provided with two and located on both sides of the frame 100. The first guide rail 201 extends along the front and rear directions of the frame 100. The first sliding portion 202 is connected to the frame 100 and is slidably installed on the first guide rail 201. The first driving cylinder 203 is provided between the first guide rail 201 and the first sliding portion 202. The first driving cylinder 203 can extend along the length direction of the first guide rail 201. The first driving cylinder 203 controls the sliding of the first sliding portion 202.

[0038] The hydraulic system 300 is arranged on the frame 100, and the hydraulic system 300 includes an oil tank 301, an oil pump 302 and a diverter 303. The oil tank 301 is provided with an oil outlet pipe 304 and an oil return pipe 305. The oil pump 302 is arranged on the oil outlet pipe 304. The diverter 303 is arranged between the oil outlet pipe 304 and the oil return pipe 305. The diverter 303 is provided with a plurality of control valves 306, wherein the first lifting cylinder 101 and the first driving cylinder 203 are respectively connected to one of the control valves 306 separately, and the control valve 306 corresponding to the first lifting cylinder 101 is used to control the movement of the first lifting cylinder 101, and the control valve 306 corresponding to the first driving cylinder 203 is used to control the movement of the first driving cylinder 203.

[0039] In the utility model, when it is necessary to press the prefabricated pipe pile into the ground, the first guide rail 201 is supported on the ground, the control valve 306 connected to the first driving cylinder 203 is turned on, and the oil pump 302 pumps the oil in the oil tank 301 into the first driving cylinder 203. The first driving cylinder 203 is actuated to control the first sliding part 202 to slide along the first guide rail 201, and the first sliding part 202 thereby drives the frame 100 to move in the front and rear directions. When the frame 100 moves to the point where the pile pressing mechanism 102 is located directly above the pile hole, the control valve 306 connected to the first lifting cylinder 101 is turned on, and the oil pump 302 pumps the oil in the oil tank 301 into the first lifting cylinder 101. The first lifting cylinder 101 can be actuated to control the pile pressing mechanism 102 to descend, and the pile pressing mechanism 102 can press the prefabricated pipe pile into the ground.

[0040] The utility model controls the first sliding part 202 to slide along the first guide rail 201 through the first driving cylinder 203, thereby driving the frame 100 to move in the front-rear direction, thereby driving the pile pressing mechanism 102 on the frame 100 to move to the top of the pile hole. Compared with driving the frame 100 to move by the rotation of the walking wheel, the utility model can make the pile pressing mechanism 102 move to the top of the pile hole more quickly and accurately, and the operation is more convenient, more time-saving and labor-saving. Moreover, the first lifting cylinder 101 and the first driving cylinder 203 are both controlled by the same hydraulic system 300 composed of the oil tank 301, the oil pump 302, the diverter 303 and the control valve 306, without the need to set up multiple hydraulic systems 300, thereby making the static pile driver smaller in size and lower in cost.

[0041] It should be noted that the frame 100 can be equipped with a lifting mechanism, which is used to lift prefabricated pipe piles. The lifting mechanism can also be connected to one of the control valves 306 separately, and the control valve 306 corresponding to the lifting mechanism controls the operation of the lifting mechanism. In the prior art, the frame 100 is controlled to move by the running wheels, and the rotation of the running wheels is converted into the movement of the frame 100. It is easy for the running wheels to rotate too much or too little. In addition, it is easy for the frame 100 to deviate from the moving direction, which makes it difficult for the frame 100 to accurately move the pile-pressing mechanism 102 to the top of the pile hole. The present application controls the movement of the frame 100 by the first driving cylinder 203, and is provided with a first guide rail 201 and a first sliding part 202, so that the frame 100 can drive the pile-pressing mechanism 102 to move quickly and accurately to the top of the pile hole.

[0042] In some embodiments of the present invention, Figure 6 and Figure 7As shown, the diverter 303 is provided with two channels 307, and the two channels 307 are respectively connected to the oil outlet pipe 304 and the oil return pipe 305, and the control valve 306 is set as a three-position four-way reversing valve. The control valve 306 is provided with two oil ports and two working ports 308, and the two oil ports are respectively connected to the two channels 307, and the rod chamber and the rodless chamber of the first lifting cylinder 101 are respectively connected to the two working ports 308 of the corresponding control valve 306, and the rod chamber and the rodless chamber of the first driving cylinder 203 are respectively connected to the two working ports 308 of the corresponding control valve 306.

[0043] In this embodiment, the control valve 306 is configured as a three-position four-way reversing valve, and the control valve 306 has two oil ports, one of which is an oil inlet and the other is an oil outlet. The oil inlet can be connected to the channel 307 connected to the oil outlet pipe 304, and the oil outlet can be connected to the channel 307 connected to the oil return pipe 305. The control valve 306 has three working states. Taking the control valve 306 connected to the first lifting cylinder 101 as an example, in the first state, the oil inlet is connected to the working port 308 of the rodless chamber connected to the first lifting cylinder 101, and the oil outlet is connected to the working port 308 of the rod chamber connected to the first lifting cylinder 101. In the second state, the oil inlet is connected to the working port 308 of the rod chamber connected to the first lifting cylinder 101, and the oil outlet is connected to the working port 308 of the rodless chamber connected to the first lifting cylinder 101. In the third state, both the oil inlet and the oil outlet are blocked. In this way, by operating the control valve 306, the lifting and lowering of the first lifting cylinder 101 can be controlled and the first lifting cylinder 101 can be stopped. The operation is convenient and saves time and effort.

[0044] In some embodiments of the present invention, Figures 2 to 4As shown, the static pile driver also includes a second walking mechanism 400, which includes a second guide rail 401, a second sliding portion 402 and a second driving cylinder. The second guide rail 401 extends along the left and right directions of the frame 100, the second sliding portion 402 is connected to the frame 100 and is slidably installed on the second guide rail 401, and the second driving cylinder is arranged between the second guide rail 401 and the second sliding portion 402 to control the sliding of the second sliding portion 402. The second driving cylinder is separately connected to one of the control valves 306, and the control valve 306 corresponding to the second driving cylinder is used to control the action of the second driving cylinder. In this embodiment, in addition to controlling the frame 100 to move in the front-rear direction through the first walking mechanism 200, the second guide rail 401 can also be supported on the ground, the control valve 306 connected to the second driving oil cylinder is turned on, and the oil pump 302 pumps the oil in the oil tank 301 into the second driving oil cylinder, and the second driving oil cylinder is actuated to control the second sliding part 402 to slide along the second guide rail 401, and the second sliding part 402 drives the frame 100 to move in the left-right direction, so that the pile driving mechanism 102 can be moved more quickly and accurately to the top of the pile hole, which is more practical. In addition, the second driving oil cylinder can also control the operation through the same hydraulic system 300, so that the static pile driver is smaller in size and lower in cost.

[0045] In some embodiments of the present invention, Figures 1 to 4 As shown, the frame 100 is provided with a second lifting cylinder 103, the first sliding part 202 is connected to the bottom end of the second lifting cylinder 103, and the second lifting cylinder 103 is connected to one of the control valves 306 separately, and the control valve 306 corresponding to the second lifting cylinder 103 is used to control the action of the second lifting cylinder 103. The control valve 306 connected to the second lifting cylinder 103 is turned on, and the oil pump 302 pumps the oil in the oil tank 301 into the second lifting cylinder 103, and the second lifting cylinder 103 can be extended and retracted, so that the first guide rail 201 and the second guide rail 401 can be staggered and supported on the ground. For example, when the frame 100 needs to be moved in the front-back direction, the second lifting cylinder 103 can be extended, and then the first guide rail 201 can be supported on the ground, and the second guide rail 401 can be separated from the ground, so that the frame 100 can be conveniently moved in the front-back direction. When the frame 100 needs to be moved left and right, the second lifting cylinder 103 can be shortened, so that the first guide rail 201 can be separated from the ground, and the second guide rail 401 can be supported on the ground, thereby facilitating the frame 100 to move left and right, making the operation more convenient and the design ingenious.

[0046] It should be noted that in some other embodiments of the present invention, the frame 100 may also be provided with a third lifting cylinder, the second sliding portion 402 is connected to the bottom end of the third lifting cylinder, the third lifting cylinder is individually connected to one of the control valves 306, and the control valve 306 corresponding to the third lifting cylinder is used to control the action of the third lifting cylinder.

[0047] In some embodiments of the present invention, Figures 2 to 4 As shown, the first guide rail 201 is provided with a first mounting groove 204 extending along the length direction of the first guide rail 201, and both sides of the first mounting groove 204 are provided with a first slide groove 205 extending along the length direction of the first guide rail 201, and the first sliding part 202 is provided with a first pulley 206 slidably installed in the first slide groove 205. The first sliding part 202 slides through the cooperation of the first pulley 206 and the first slide groove 205. Such a setting not only makes the friction force of the first sliding part 202 smaller when sliding, and the sliding is smoother, which can reduce the occurrence of stuck phenomenon, but also makes the movement of the rack 100 more accurate, which can reduce the occurrence of offset. In addition, the first sliding part 202 can also drive the first guide rail 201 to separate from the ground, which is practical.

[0048] In some embodiments of the present invention, Figures 2 to 4 As shown, both sides of the first installation groove 204 are provided with first support rails 207 extending along the length direction of the first guide rail 201, the first pulley 206 is slidably installed on the first support rails 207, and the tops of the two side walls of the first installation groove 204 are provided with first limit plates 208, and a first slide groove 205 is formed between the first limit plate 208 and the first support rail 207. Such a configuration not only makes the installation of the first pulley 206 more convenient, but also makes the sliding smoother, and the first support rail 207 can support a heavier rack 100. In addition, the first limit plate 208 is provided, so that the first sliding part 202 can drive the first guide rail 201 to separate from the ground, which is practical.

The second sliding part 402 slides through the cooperation of the second pulley 405 and the second slide groove 404. Such a setting not only makes the friction force of the second sliding part 402 smaller when sliding, and the sliding is smoother, which can reduce the occurrence of stuck phenomenon, but also makes the movement of the rack 100 more accurate, which can reduce the occurrence of offset. In addition, the second sliding part 402 can also drive the second guide rail 401 to separate from the ground, which is practical.

[0050] In some embodiments of the present invention, Figure 4As shown, both sides of the second mounting groove 403 are provided with second support rails 406 extending along the length direction of the second guide rail 401, the second pulley 405 is slidably installed on the second support rails 406, and the tops of the two side walls of the second mounting groove 403 are provided with second limit plates 407, and a second slide groove 404 is formed between the second limit plates 407 and the second support rail 406. Such a configuration not only makes the installation of the second pulley 405 more convenient, but also makes the sliding smoother, and the second support rail 406 can support a heavier rack 100. In addition, the second limit plate 407 is provided, so that the second sliding part 402 can drive the second guide rail 401 to separate from the ground, which is practical.

[0051] In some embodiments of the present invention, the control valve 306 is configured as a solenoid valve. With this configuration, the opening and operation of the control valve 306 can be controlled remotely by a remote controller, without the need for manual operation of the control valve 306, which makes the operation more convenient and faster, saves time and effort, and is safer.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
