[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Nowadays, wind turbines are developing towards large-scale, which puts forward higher requirements for the installation of wind power foundations. There is an urgent need for large-scale pile driving equipment with high energy transfer rate, convenient and accurate regulation, low noise, and small pollution. Therefore, hydraulic pile hammers have emerged as the times require.

[0027] As an offshore pile driving device, the hydraulic pile hammer has a complex structure and is inconvenient to install. It is difficult to transport it to the sea and then equip it. Therefore, the hydraulic pile hammer should be installed at the dock and then lifted onto the transport ship by a crane, fixed with guy ropes, and then transported to the wind farm.

[0028] However, this transportation method fixed with guy ropes has the following problems: 1. The sea waves are relatively large, and there are greater potential safety hazards during the transportation process. 2. The hydraulic pile hammer is directly placed on the transport ship, and its maintenance and rectification are not very convenient. 3. The hydraulic pile hammer is directly placed on the transport ship, and the anvil will press on the pile driving body for a long time, and there is a risk of deformation of the pile driving body.

[0029] The present utility model provides a storage and transportation base for a hydraulic pile hammer as shown in Figures 1 to 6 including a base 4, a pile driving body 6 is arranged at the top of the base 4, a support cylinder 1 is arranged inside the pile driving body 6, a support cylinder 1 is arranged at the top of the base 4, a guide seat 2 is arranged at the top of the base 4, and the guide seat 2 is located on the outer cylindrical surface of the pile driving body 6 and is used for limiting the position of the pile driving body 6.

[0030]

[0031] ​During use, the base 4 supports the support cylinder 1, and the pile-driving body 6 outside the support cylinder 1 limits the position of the anvil 7. The guide seat 2 of the base 4 is adjusted so that the guide seat 2 contacts the pile-driving body 6 to limit the position of the pile-driving body 6 and prevent the pile-driving body 6 from moving during transportation.

[0032] The guide seat 2 includes a bottom plate 201, and a support plate 202 is provided at the top end of the bottom plate 201. One end of the support plate 202 is used for limiting the position of the pile-driving body 6, and kidney-shaped holes 203 are symmetrically formed at the top end of the bottom plate 201.

[0033] During use, the bottom plate 201 of the guide seat 2 is fixed to the top end of the base 4, and the support plate 202 at the top end of the bottom plate 201 is clamped with the pile-driving body 6. The support plate 202 limits the position of the pile-driving body 6 through the movement of the bottom plate 201.

[0034] The base 4 is provided with threaded holes, and the threaded holes are arranged corresponding to the kidney-shaped holes 203.

[0035] During use, threaded holes are formed at the top end of the base 4, and the positions of the threaded holes are on the movement track of the guide seat 2. The threaded holes cooperate with the kidney-shaped holes 203, and the guide seat 2 is fixed to the top end of the base 4 through bolts. When large-scale adjustment is required, the bolts are taken out, and the guide seat 2 moves towards the pile-driving body 6 direction. Then, the base 4 and the guide seat 2 are connected through bolts. After large-scale movement, fine adjustment is carried out. The bolts are loosened, and the guide seat 2 is adjusted through the kidney-shaped holes 203 of the bottom plate 201 so that the guide seat 2 contacts the pile-driving body 6 and limits its position, making it safer and more stable during transportation.

[0036] The support cylinder 1 includes a cylinder body 101, reinforcing ribs 102 are arranged inside the cylinder body 101, reinforcing plates 103 are arranged on the outer circular surface of the cylinder body 101, and second lifting lugs 104 are arranged on the inner side wall of the cylinder body 101. The second lifting lugs 104 are located above the reinforcing ribs 102.

[0037] During use, the cylinder body 101 is made of rolled steel plates, the cylinder body 101 is cylindrical, and reinforcing ribs 102 are arranged on both the upper and lower sides inside the cylinder body 101. The reinforcing ribs 102 are cross-shaped, and the four ends of the reinforcing ribs 102 support and fix the side wall of the cylinder body 101. There are a total of eight ends for the two reinforcing ribs 102, which are distributed on the inner side wall of the cylinder body 101 to enhance its structural stability. The reinforcing plates 103 outside the cylinder body 101 are mainly used to support the hammer body and the anvil. The cylinder body 101 is supported by the reinforcing plates 103 and the reinforcing ribs 102 to ensure that the side wall of the cylinder body 101 will not bend or deform during the support of the anvil 7, affecting the support effect.

[0038] [[ID = 21]]The second lifting lug 104 is used for hoisting and transportation during installation.

[0039] A retaining wall 401 is provided at the top of the base 4, and a cylinder 101 is provided inside the retaining wall 401.

[0040] During use, the retaining wall 401 at the top of the base 4 performs a preliminary position limitation on the support cylinder 1. The support cylinder 1 is installed inside the retaining wall 401, and the retaining wall 401 cooperates with the bottom end of the support cylinder 1 to fix the support cylinder 1, preventing the support cylinder 1 from shifting during the process of supporting the anvil 7.

[0041] A climbing mechanism 5 is provided on the side wall of the base 4, and first lifting lugs 3 are provided at the four corners of the top of the base 4.

[0042] During use, the base 4 is used to support the overall structure. The support cylinder 1 is arranged on its upper surface. The first lifting lugs 3 on its upper surface are used for the hoisting arrangement of the base 4. Circular holes and a climbing mechanism 5 are provided on its side surface, facilitating workers to enter the inside of the pile driver body for maintenance and modification of the pile driver body structure; the upper and lower surfaces of the base 4 are provided with perforated plates, which can reduce the weight and facilitate personnel entry on the one hand, and on the other hand, since the pressure per square meter on a sea vessel is limited, the pressure per square meter can be reduced to ensure the safety of transportation.

[0043] The base 4 is provided with a manhole. When it is necessary to weld or remove the reduced-diameter device, the transformers can directly enter the inside of the pile driver body through the manhole for operation, without the need to disassemble the hammer body and the anvil, which can greatly shorten the transformation period.

[0044] An anvil 7 is provided at the top of the support cylinder 1, and the anvil 7 is located inside the pile driver body 6.

[0045] During use, the support cylinder 1 supports the anvil 7, preventing the anvil 7 from directly contacting the pile driver body 6, and effectively preventing the anvil 7 and the hammer core from being directly placed on the pile driver body 6 for a long time, thereby preventing the pile driver body 6 from deforming.

[0046] Working principle

[0047] When it is necessary to transport the support cylinder 1, the support cylinder 1 is hoisted through the second lifting lug 104, and the support cylinder 1 is hoisted into the retaining wall 401 of the base 4. The retaining wall 401 performs a preliminary position fixation on the support cylinder 1. After that, when a large-scale adjustment is required, the bolts are removed, the guide seat 2 moves towards the pile driver body 6, and then the base 4 is connected to the guide seat 2 through bolts. After a large-scale movement, for fine adjustment, the bolts are loosened, and the guide seat 2 is adjusted through the waist-shaped holes 203 of the bottom plate 201 so that the guide seat 2 contacts the pile driver body 6 and its position is limited, making the transportation safer and more stable.

[0048] During the support process, the cylinder body 101 is formed by rolling steel plates. The cylinder body 101 is circular. Reinforcing ribs 102 are arranged on both the upper and lower sides inside the cylinder body 101. The reinforcing ribs 102 are in a cross shape. The four ends of the reinforcing ribs 102 support and fix the side wall of the cylinder body 101. There are a total of eight ends for the two reinforcing ribs 102, which are distributed on the inner side wall of the cylinder body 101 to enhance its structural stability. The reinforcing rib plates 103 outside the cylinder body 101 are mainly used to support the hammer body and the anvil. Through the reinforcing rib plates 103 and the reinforcing ribs 102, the cylinder body 101 is supported to ensure that during the support of the anvil 7, the side wall of the cylinder body 101 will not bend or deform, affecting the support effect.

[0049] The base 4 is used to support the overall structure. The support cylinder 1 is arranged on its upper surface. The first lifting lug 3 on its upper surface is used for the hoisting arrangement of the base 4. Round holes and a climbing mechanism 5 are provided on its side surface, which is convenient for workers to enter the inside of the pipe pile driver to repair and modify the structure of the pipe pile driver; the upper and lower surfaces of the base 4 are provided with hollowed-out plates. On the one hand, it can reduce the weight and facilitate the entry and exit of personnel. On the other hand, since the pressure per square meter on a sea vessel is limited, it can reduce the pressure per square meter on it to ensure the safety of transportation.

[0050] The base 4 is provided with a manhole. When it is necessary to weld or remove the reducing device, the transformers can directly enter the inside of the pipe pile driver through the manhole for operation, without the need to disassemble the hammer body and the anvil, which can greatly shorten the transformation period.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
