Description

Technical Field

[0001] This utility model relates to the field of engineering machinery and equipment technology, and in particular to a pile frame and pile driver. Background Technology

[0002] The pile frame is an important component of the pile driver. Various pile foundation construction devices, such as pile driving and drilling equipment, need to be mounted on the pile frame for construction operations.

[0003] When using a rammer for pile driving, the wire rope suspending the rammer typically has the following types of suspension points:

[0004] The first type involves the steel wire rope for jacking the ramming hammer passing through the gooseneck pulley at the top of the column. This structure requires a longer steel wire rope, and the transition pulleys are all located at the top of the column, resulting in a high center of gravity and poor stability. It is suitable for applications with a large lifting range.

[0005] The second method involves adding a pulley block in the middle of the column. Although this can shorten the length of the wire rope for lifting the object, the pulley blocks currently used are numerous and have a complex structure.

[0006] The third method involves adding a secondary support column, with a small goose head added to the top of the secondary support column. Although this can also shorten the length of the hoisting wire rope, the structure is relatively complex and increases the weight of the secondary support column.

[0007] Therefore, how to improve the stability of the pile frame and reduce the length of the wire rope for the tamping hammer to save costs is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 3 .

[0030] The present invention provides a pile frame comprising: a column 1, a pulley assembly 2, and a lifting rope 3. The pulley assembly 2 is located in the middle section of the column 1, wherein the middle section is a range of the column 1. The pulley assembly 2 can be located in the middle, lower, or upper part of the column 1 in the axial direction. The pulley assembly 2 includes a first pulley 21 and a second pulley 22 located on both sides of the column 1. The column 1 is provided with a rope hole 11, wherein the rope hole 11 can be along the radial direction of the column 1. For example, when the column 1 is a hollow structure, the rope hole 11 penetrates the side wall of the column 1, meaning that the side wall of the column 1 has two coaxial rope holes 11. The suspension rope 3 passes through the rope hole 11 and is wound around the first pulley 21 and the second pulley 22. For example, one end of the suspension rope 3 is connected to the winch 5, and the other end is wound around the second pulley 22, passes through the rope hole 11, and then is wound around the first pulley 21. When the tamping hammer 4 is needed, the tamping hammer 4 can be connected to the end of the suspension rope 3 that is wound around the first pulley 21. By setting the rope hole 11 on the column 1, it is easy for the suspension rope 3 to be wound around the first pulley 21 and the second pulley 22, and the length of the suspension rope 3 can be reduced, which can effectively save costs. In addition, setting the pulley assembly 2 in the middle section of the column 1 can improve the stability and safety of the whole machine.

[0031] In some embodiments, the pulley assembly 2 further includes a first pulley support frame 211 and a second pulley support frame 221. The first pulley 21 is hinged to the first pulley support frame 211 via a first pin 212. The first pulley support frame 211 is movably connected to the column 1 along the radial direction of the column 1. Specifically, the radial position of the first pulley support frame 211 relative to the column 1 can be adjusted according to construction needs. During transportation, the first pulley support frame 211 can be moved toward the column 1 to avoid the first pulley support frame 211 extending too far and affecting transportation safety. The second pulley 22 is hinged to the second pulley support frame 221 via a second pin 222. The second pulley support frame 221 is connected to the column 1 and can be welded to the column 1.

[0032] In some embodiments, a guide support portion 12 extending outward is provided on one side of the column 1, that is, the guide support portion 12 is a structure protruding from the outside of the column 1. The first pulley support frame 211 can move relative to the guide support portion 12. After moving to the desired position, the first pulley support frame 211 is connected to the guide support portion 12 by a fastener 14. Specifically, the guide support portion 12 has a guide hole, and its side wall has a connecting hole. The side wall of the first pulley support frame 211 has multiple adjusting holes 2113 distributed along its movable direction. The fastener 14 is selectively inserted into one of the adjusting holes 2113 and the connecting hole to adjust the distance between the first pulley 21 and the second pulley 22. For example, when the first pulley support frame 211 moves towards the column 1, the distance between the first pulley 21 and the column 1 can be reduced; when the first pulley support frame 211 is pulled outward, the distance between the first pulley 21 and the column 1 can be increased. Figure 3 As shown, the first pulley support frame 211 is provided with three adjustment holes 2113, and the guide support part 12 is provided with a connection hole. During installation, one of the adjustment holes 2113 can be selected to correspond with the connection hole, and then the fastener 14 can be inserted into the corresponding adjustment hole 2113 and the connection hole to fix the first pulley support frame 211 and the guide support part 12.

[0033] In some embodiments, such as Figure 3 As shown, a reinforcing rib 13 is provided between the bottom of the guide support 12 and the side of the column 1. The reinforcing rib 13 can improve the support strength of the guide support 12, thereby ensuring the working stability of the pulley assembly 2. The upper surface of the reinforcing rib 13 is fixed to the bottom of the guide support 12, and one side is fixed to the side of the column 1. For example, it can be fixed by welding. The reinforcing rib 13 is preferably a triangular rib structure.

[0034] In some embodiments, the guide support 12 is a square tube 2112, and the first pulley support frame 211 includes a pulley seat 2111 and a square column. The pulley seat 2111 is located at one end of the square column, and the first pulley 21 is rotatably connected to the pulley seat 2111 via a first pin 212. The pulley seat 2111 and the square column are fixedly connected, wherein the square column is movably connected inside the square tube 2112. Specifically, as shown... Figure 3 As shown, the square column is provided with multiple adjustment holes 2113, and each adjustment hole 2113 is evenly distributed along the moving direction of the square column. The axial direction of each adjustment hole 2113 is preferably horizontal. Correspondingly, the connecting hole on the square tube 2112 is also horizontal. The cross-section of the square tube 2112 and the square column has a longer length in the vertical direction than in the horizontal direction. That is, the square tube 2112 and the square column are preferably rectangular structures.

[0035] In some embodiments, the end of the square tube 2112 facing the first pulley 21 is provided with a flange, for example... Figure 3 As shown, the flange on the square tube 2112 is a rectangular frame structure, which can improve the structural strength of the square tube 2112.

[0036] In some embodiments, the axes of the adjusting hole 2113 and the connecting hole are parallel to the rotation axis of the first pulley 21. For example Figure 3 As shown, the axes of the first pin 212, the adjusting hole 2113, the connecting hole, and the second pin 222 all extend horizontally. Furthermore, to improve the connection stability between the first pulley support frame 211 and the guide support 12, mounting holes distributed vertically can be provided on the first pulley support frame 211 and the guide support, wherein the mounting holes should be staggered from the adjusting hole 2113 and the connecting hole.

[0037] In some embodiments, a sleeve is provided in the rope hole 11, and the suspension rope 3 is passed through the sleeve. The suspension rope 3 is preferably a steel wire rope. The sleeve can be made of a wear-resistant material. The sleeve can prevent the suspension rope 3 from directly rubbing against the column 1. When the sleeve is worn, it can be replaced, which can reduce maintenance costs compared to the wear of the column 1.

[0038] In some embodiments, the column 1 includes multiple axially distributed sub-columns, with adjacent sub-columns connected by flanges. The pulley assembly 2 is disposed on the sub-column located in the middle. It should be noted that the middle sub-column refers to any sub-column except for the bottom and top ends. The number of sub-columns can be selected according to actual needs, and this embodiment does not specifically limit this.

[0039] This utility model embodiment also provides a pile driver, including the pile frame provided in any of the above embodiments, and further including a machine frame and a diagonal bracing drive device. The lower end of the pile frame is hinged to the machine frame, and both ends of the diagonal bracing drive device are hinged to the machine frame and the pile frame. The diagonal bracing drive device is used to drive the pile frame to erect or lower the mast. During transportation, the diagonal bracing drive device can drive the pile frame to lower the mast to keep the pile frame in a horizontal state, thus facilitating transportation; during construction, the diagonal bracing drive device can drive the pile frame to erect the mast to keep the pile frame in a vertical state. The beneficial effects of the pile driver can be referred to the pile frame provided in the above embodiments, and will not be repeated here.

[0040] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0041] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
