[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-4The present embodiment provides a hydraulic pile pulling device that is easy to position, including a base 1 and a wooden pile 18. The upper end of the base 1 is fixedly connected to a hydraulic lifting cylinder 2, the upper end of the hydraulic lifting cylinder 2 is fixedly connected to a mounting frame 3, the front two sides of the mounting frame 3 are fixedly connected to fixing blocks 4, the fixing blocks 4 are fixedly connected to a positioning frame 5 on one side close to each other, a plurality of limiting plates 6 are equidistantly installed in the positioning frame 5, and the limiting plates 6 can rotate in the positioning frame 5. By using the rotatable limiting plate 6 structure, when the wooden pile 18 needs to be positioned to enter the clamping frame 14, the wooden pile 18 is limited so that the wooden pile 18 can only enter vertically from the upper end, thereby achieving the purpose of positioning.

[0019] Specifically, there are six limit plates 6, and the six limit plates 6 can be assembled into a funnel. In order to facilitate recovery after use, a spring 7 is fixedly connected to the outside of the limit plate 6, and then the spring 7 is fixedly connected to the inner wall of the positioning frame 5 on the side away from the limit plate 6, and then a telescopic rod 8 is fixedly connected to the outside of the limit plate 6, and the telescopic rod 8 is fixedly connected to the inner wall of the positioning frame 5 on the side away from the limit plate 6. The set telescopic rod 8 structure plays the role of the limit spring 7 to prevent the spring 7 from excessive tilting.

[0020] When the fixing ring 10 descends and contacts the positioning frame 5, the connecting rope 9 no longer stretches the limiting plate 6, so that the spring 7 on one side of the limiting plate 6 pushes the limiting plate 6 to recover, so that the limiting plate 6 clamps the wooden pile 18, playing an auxiliary clamping role.

[0021] A connecting rope 9 is also fixedly connected to the outside of the limiting plate 6, the upper end of the connecting rope 9 is fixedly connected to a fixing ring 10, and both sides of the fixing ring 10 are fixedly connected to fixing plates 11, and both sides of the fixing plate 11 are slidingly connected to the baffle installed on the fixing block 4, one side of the fixing plate 11 is threadedly connected to an adjusting rod 12, and the lower end of the adjusting rod 12 is fixedly connected to a motor 13, and the motor 13 is fixed in the fixing block 4.

[0022] The motor 13 drives the adjusting rod 12 to rotate, thereby driving the fixing ring 10 on one side to rise and fall, and driving the connecting rope 9 to move, so that the connecting rope 9 can drive the limiting plate 6 at the lower end to rotate for use.

[0023] Then, a clamping frame 14 is fixedly connected to the upper end of the fixing ring 10 , and threaded rods 15 are threadedly connected to the clamping frame 14 on both sides. One side of the threaded rod 15 is rotatably connected to the clamping plate 16 , and the clamping plate 16 can be moved by rotating the threaded rod 15 , so that the clamping plate 16 approaches and clamps the wood pile 18 .

[0024] In order to ensure the stability of the lifting and lowering of the fixing ring 10, a limit rod 17 is also slidably connected to the middle of the fixing plate 11 on the side away from the adjusting rod 12, and the lower end of the limit rod 17 is fixedly connected to the fixing block 4 on the same side. The set limit rod 17 can ensure the stability of the lifting and lowering of the fixing plate 11 and the fixing ring 10 driven by the adjusting rod 12, and avoid the problem that the wooden pile 18 cannot pass through the fixing ring 10 due to the tilt of the fixing ring 10.

[0025] When the utility model is used, the base 1 is moved to make the positioning frame 5 at the upper end close to the wood pile 18, and then the motor 13 is started first, so that the motor 13 drives the adjusting rod 12 to rotate, so that the adjusting rod 12 drives the fixing plate 11 thereon to move, so that the fixing plate 11 drives the fixing ring 10 on one side to rise, and the fixing ring 10 drives the connecting rope 9 to rise and pulls the limiting plate 6 located at the lower end in the positioning frame 5 to rotate, so that the six limiting plates 6 are opened to form an inverted funnel shape, and then the hydraulic lifting cylinder 2 is started again, so that the mounting frame 3 drives the fixing block 4 to descend, so that the positioning frame 5 and the fixing ring 10 and the clamping frame 14 descend together, so that the positioning frame 5 descends and covers the wood pile 18, and the wood pile 18 is limited by the limiting plate 6. It will enter the middle part of the positioning frame 5 and vertically enter the fixing ring 10, so that it is limited by the fixing ring 10 and enters the clamping frame 14, so that the wood pile 18 is quickly connected to the clamping frame 14, and then the motor 13 is started to make the adjusting rod 12 drive the fixing plate 11 to descend, and make one side of the fixing ring 10 descend, so that the lower end of the fixing ring 10 contacts the positioning frame 5, and then the threaded rod 15 is rotated to make the threaded rod 15 drive the clamping plate 16 to approach the wood pile 18 and clamp the wood pile 18, and then the hydraulic lifting cylinder 2 can be started to make the hydraulic lifting cylinder 2 drive the fixing block 4 to move, and the fixing block 4 drives the fixing ring 10, the positioning frame 5 and the clamping frame 14 to rise, thereby driving the clamped wood pile 18 to rise and pull up the wood pile 18.
