Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a rotary table mounting structure for a dynamic compaction machine and the dynamic compaction machine itself. Background Technology

[0002] Tracked dynamic compaction machines are mechanical devices with tracked chassis that use hammers to fall freely or nearly freely from a certain height to compact soil layers, rapidly densifying the foundation. As a highly efficient dynamic compaction equipment, tracked dynamic compaction machines have a very strong market demand, and models specifically designed for methods such as standalone SDDC (Single-Drilling Dynamic Compaction), deep-hole dynamic compaction, single-extraction, and detached dynamic compaction are becoming increasingly mature. However, as the compaction energy of these products increases, a single model suitable for only one method is no longer sufficient to meet project requirements; combinations of models and methods can bring greater economic benefits to customers.

[0003] Traditional dynamic compaction machines typically have a single lifting mechanism, suitable for a specific fixed construction method. However, a typical dynamic compaction project, from start to finish, requires the combined use of different methods such as SDDC (Single-Drilled Concrete Mixing), deep-hole dynamic compaction, single-extraction, and unhooked dynamic compaction. Therefore, traditional dynamic compaction projects necessitate the purchase of multiple machines, resulting in high costs. Consequently, the development of a multi-method dynamic compaction machine adaptable to two or more construction methods is urgently needed.

[0004] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of this invention, and should not be construed as an admission or implication in any way that such information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0037] The dynamic compaction machine uses a turntable as a platform structure for installing components such as the hoisting mechanism, luffing mechanism, and A-frame. The hoisting mechanism, including the winch, motor, and wire rope, enables the free lifting and lowering of the hammer. The luffing mechanism, including the winch, motor, and wire rope, enables the luffing movement of the boom system. The A-frame is a box-type or truss structure, primarily serving the functions of load-bearing and force transmission.

[0038] The working conditions of dynamic compaction machines are very complex, and they are subjected to alternating loads for a long time, which puts great pressure on the load-bearing capacity of the structural components. Dynamic compaction machines applicable to multiple construction methods need to be equipped with two lifting mechanisms (including front and rear lifting winches), which puts great stress on the turntable structure.

[0039] To this end, the present application has made structural improvements to the turntable installation structure of the dynamic compactor to enhance the bearing capacity of the turntable installation structure, enabling the dynamic compactor to adapt to various construction methods.

[0040] As shown Figures 1 to 3 In some embodiments of the turntable installation structure of the dynamic compactor provided in the present application, the turntable installation structure includes a mounting plate 1, a first support plate 2, a cover plate 3, and a first mounting seat 4. The mounting plate 1 is used to mount the turntable. Two first support plates 2 are mounted on the mounting plate 1, and a preset angle is provided between the first support plate 2 and the mounting plate 1. The cover plate 3 is connected to the first side surfaces of the two first support plates 2 that are away from the mounting plate 1. The first mounting seat 4 is mounted on the cover plate 3 and is used to mount the first winch.

[0041] Among them, the connection point of the first mounting seat 4 connected to the first winch is within the range of the projection of the first support plate 2 on the cover plate 3.

[0042] In the embodiments of the present invention, by setting the connection point of the first mounting seat 4 connected to the first winch within the range of the projection of the first support plate 2 on the cover plate 3, there can be a direct support of the first support plate 2 directly below the connection point of the first mounting seat 4 connected to the first winch, improving the support capacity of the turntable installation structure for the first winch, and further enhancing the overall bearing capacity of the turntable installation structure, enabling the dynamic compactor to adapt to various construction methods.

[0043] By setting the connection point of the first mounting seat 4 connected to the first winch within the range of the projection of the first support plate 2 on the cover plate 3, when the first winch is subjected to a tensile force, the tensile force will be directly transmitted to the first support plate 2 through the connection point of the first mounting seat 4 connected to the first winch. The more direct the force transmission path, the more friendly it is to the bearing capacity test of the force-bearing components. Therefore, the requirement for the load-bearing capacity of the turntable installation structure can be reduced.

[0044] In the embodiments of the present invention, the mounting plate 1, the two first support plates 2, and the cover plate 3 are connected to form a box-shaped structure, which can greatly improve the load-bearing capacity of the turntable installation structure.

[0045] In some embodiments, the turntable installation structure of the dynamic compactor further includes a first connecting member. The first winch is provided with a first mounting hole, and the first mounting seat 4 is provided with a second mounting hole 401. The first connecting member passes through the first mounting hole and the second mounting hole 401 to connect the first winch and the first mounting seat 4. The axis of the first mounting hole and the axis of the second mounting hole 401 are collinear and pass through the first side surface of the first support plate 2.

[0046] By making the axis of the first mounting hole and the axis of the second mounting hole 401 collinear and passing through the first side of the first support plate 2, the tension from the first winch on the first connecting member can be directly transmitted to the first support plate 2. That is, the first support plate 2 can directly support the external force transmitted from the first winch, effectively improving the load-bearing capacity of the turntable installation structure.

[0047] The first connecting component can be a bolt or screw, etc.

[0048] In some embodiments, the axis of the first mounting hole intersects the centerline of the first side surface of the first support plate 2 along its length.

[0049] By aligning the axis of the first mounting hole with the centerline of the first side of the first support plate 2 along its length, the external force received by the first winch can be directly transmitted to the centerline of the first support plate 2 through the first connector, making the first support plate 2 receive the external force more evenly and improving the support stability of the first support plate 2.

[0050] The length direction of the first side is Figure 1 The direction shown is from left to right, that is, from the front end to the rear end of the mounting plate 1, or the direction from the mounting portion 102 to the extension portion 103 of the mounting plate 1, which will be mentioned later.

[0051] In some embodiments, the first support plate 2 is perpendicular to the mounting plate 1. That is, the included angle between the first support plate 2 and the mounting plate 1 is 90°.

[0052] By setting the first support plate 2 perpendicular to the mounting plate 1, the extension direction of the first support plate 2 can be kept parallel to the force direction of the first winch, thus optimizing the force distribution of the first support plate 2 and improving its load-bearing capacity.

[0053] like Figure 4 As shown, in some embodiments, the rotating platform mounting structure of the dynamic compaction machine further includes a second support plate 5 and a third support plate 6 mounted on the mounting plate 1. The mounting plate 1 is provided with a plurality of third mounting holes 101 for mounting the rotating platform. The plurality of third mounting holes 101 are arranged in a circle along the circumference. The second support plate 5 is located on the inner side of the circle, and the third support plate 6 is located on the outer side of the circle.

[0054] By setting a second support plate 5 and a third support plate 6 on the inner and outer sides of the circle respectively, the rigidity of the mounting plate 1 can be improved, and the outer edge of the mounting plate 1 can be prevented from being in a state of alternating upward and downward deflection due to external forces, thus effectively improving the load-bearing capacity of the mounting plate 1.

[0055] In some embodiments, the second support plate 5 is arc-shaped so that the distance between the second support plate 5 and the circle is constant in the circumferential direction; and / or, the third support plate 6 is arc-shaped so that the distance between the third support plate 6 and the circle is constant in the circumferential direction.

[0056] By setting the second support plate 5 and / or the third support plate 6 to an arc shape, and making the distance between the second support plate 5 and / or the third support plate 6 and the circle constant in the circumferential direction, the strength of the inner and outer sides of the circle can be uniformly enhanced, the force balance of the inner and outer sides can be maintained, and the overall stability of the mounting plate 1 can be improved.

[0057] In some embodiments, the dynamic compaction machine turntable mounting structure further includes a fourth support plate 7 mounted on the mounting plate 1, the fourth support plate 7 being connected between the second support plate 5 and the third support plate 6.

[0058] By setting a fourth support plate 7 between the second support plate 5 and the third support plate 6, the structural strength of the second support plate 5 and the third support plate 6 can be improved.

[0059] In some embodiments, the dynamic compaction machine turntable mounting structure further includes two fifth support plates 8 mounted on the mounting plate 1. The two fifth support plates 8 are respectively arranged adjacent to the corresponding first support plates 2 and are both located between the two first support plates 2. The fifth support plates 8 are located inside the circle and are connected to the second support plate 5.

[0060] By setting two fifth support plates 8, the structural strength of the two first support plates 2 can be enhanced.

[0061] In some embodiments, the fifth support plate 8 is disposed close to the first support plate 2 so as to increase the thickness of the first support plate 2 and improve the structural strength of the first support plate 2.

[0062] In some embodiments, the rotating platform mounting structure of the dynamic compaction machine further includes a first stiffening plate 9, which is connected between the second support plate 5 and the fifth support plate 8.

[0063] By setting a first stiffening rib 9 between the second support plate 5 and the fifth support plate 8, the structural strength of the second support plate 5 and the fifth support plate 8 can be effectively improved, and the overall load-bearing capacity of the turntable installation structure can be enhanced.

[0064] In some embodiments, the dynamic compaction machine turntable mounting structure further includes a second mounting seat 10 mounted on the cover plate 3 for mounting a second winch. The mounting plate 1 includes a mounting portion 102 for mounting the turntable and an extension portion 103 extending from the end of the mounting portion 102. A first mounting seat 4 is disposed above the mounting portion 102, and a second mounting seat 10 is disposed above the extension portion 103.

[0065] This invention enhances the load-bearing capacity of the turntable mounting structure, enabling it to support two winches. The first mounting base 4 and the second mounting base 10 are arranged at intervals along the front-rear direction of the mounting plate 1, respectively supporting the first and second winches.

[0066] In some embodiments, the connection point of the second mounting base 10 to the second winch is located within the range of the projection of the first support plate 2 onto the cover plate 3.

[0067] Furthermore, the rotating platform mounting structure of the dynamic compaction machine also includes a second connector. The second mounting base 10 is provided with a fourth mounting hole 1001, and the second winch is provided with a fifth mounting hole. The second connector passes through the fourth mounting hole 1001 and the fifth mounting hole to connect the second winch and the second mounting base 10. The axis of the fourth mounting hole 1001 and the axis of the fifth mounting hole are collinear and pass through the first side of the first support plate 2.

[0068] In some embodiments, the axis of the fourth mounting hole 1001 intersects the centerline of the first side surface of the first support plate 2 along its length.

[0069] In some embodiments, the dynamic compaction machine turntable mounting structure further includes a first connecting structure 11 and a second connecting structure 12 for mounting an A-frame. The first connecting structure 11 is disposed between the first mounting base 4 and the second mounting base 10, and the second connecting structure 12 is disposed on the side of the second mounting base 10 away from the first mounting base 4.

[0070] In some embodiments, the first support plate 2 extends from below the mounting portion 102 to below the second connecting structure 12.

[0071] The first support plate 2 extends from below the mounting part 102 to below the second connecting structure 12, that is, the first support plate 2 runs through the front and back, which can achieve the continuity of support in the front and back direction, and serves as the main load-bearing component in the vertical direction.

[0072] like Figure 5 As shown, in some embodiments, the dynamic compaction machine turntable mounting structure also includes two sixth support plates 13. The two sixth support plates 13 are respectively arranged adjacent to the corresponding first support plates 2 and are both located between the two first support plates 2. The sixth support plates 13 extend from the rear of the third support plate 6 to the bottom of the second connecting structure 12.

[0073] By providing a sixth support plate 13 extending below the second connecting structure 12 behind the third support plate 6, the structural strength of the first support plate 2 located behind the third support plate 6 can be enhanced.

[0074] In some embodiments, the dynamic compaction machine turntable mounting structure further includes a second stiffening plate 14 disposed between two sixth support plates 13.

[0075] By setting the second stiffener 14, the structural strength of the sixth support plate 13 and the first support plate 2 can be further enhanced.

[0076] The following is in conjunction with the appendix Figures 1 to 5 The structure of one embodiment of the dynamic compaction machine turntable mounting structure of the present invention will be described as follows:

[0077] like Figures 1 to 5 As shown, the rotating platform mounting structure of the dynamic compaction machine includes a mounting plate 1, a first support plate 2, a cover plate 3, a first mounting seat 4, a second support plate 5, a third support plate 6, a fourth support plate 7, a fifth support plate 8, a first stiffening plate 9, and a second mounting seat 10.

[0078] Mounting plate 1 includes mounting portion 102 and extension portion 103. Mounting portion 102 is circular and has a plurality of third mounting holes 101 arranged at equal intervals along the circumference. The slewing bearing is mounted on mounting portion 102 through the third mounting holes 101. Extension portion 103 is generally elongated and is connected to mounting portion 102.

[0079] Two parallel first support plates 2 are mounted on the mounting plate 1, and the first support plates 2 are perpendicular to the mounting plate 1. The tops of the two first support plates 2 are connected by a cover plate 3. The cover plate 3 is parallel to the mounting plate 1. The mounting plate 1, the two first support plates 2, and the cover plate 3 are connected to form a box-shaped structure.

[0080] The cover plate 3 includes a front cover plate 301 and a rear cover plate 302. A seventh support plate 24 is provided between the front cover plate 301 and the rear cover plate 302. A first mounting seat 4 is mounted on the front cover plate 301, and a second mounting seat 10 is mounted on the rear cover plate 302.

[0081] The first mounting base 4 is provided with a second mounting hole 401 for mounting the first winch, and the second mounting base 10 is provided with a fourth mounting hole 1001 for mounting the second winch.

[0082] During the lifting and lowering of the hammer in the dynamic compaction machine, the turntable installation structure is subjected to alternating loads, which places great demands on the structural strength and rigidity. In order to achieve a small amount of plate material and a high load-bearing capacity while meeting the assembly space requirements, it is necessary to conform to the requirements of the direct force transmission route as much as possible.

[0083] For dynamic compaction machines, the hoisting winch's wire rope is constantly being lifted and lowered, while the winch mounting base is constantly under tension and compression. Therefore, the force transmission path is crucial. A third connecting structure 19 for connecting the main boom is mounted on the first support plate 2. The first support plate 2 extends from the front end to the rear end of the mounting plate 1, and is approximately equal in length to the mounting plate 1. The first support plate 2 is the main vertical load-bearing structure. The mounting holes on the first mounting base 4 and the second mounting base 10 are collinear with the first support plate 2. That is, the axis of the second mounting hole 401 and the axis of the fourth mounting hole 1001 both pass through the centerline of the first support plate 2 along its length, so that the tension experienced by the first and second winches is directly transmitted to the centerline of the first support plate 2, maximizing direct force transmission.

[0084] Furthermore, the outer edge of the third mounting hole 101 of the slewing bearing between the first and second winches is constantly in a state of alternating upward and downward deflection. The magnitude of its stiffness and the degree of stiffness transition directly affect the stress and strain of the turntable mounting structure. Therefore, a second support plate 5 and a third support plate 6 are respectively provided on the inner and outer sides of the circle containing the third mounting hole 101. To ensure the stiffness of the second support plate 5 and the third support plate 6, a fourth support plate 7 is provided between the second support plate 5 and the third support plate 6.

[0085] Both the second support plate 5 and the third support plate 6 are arc-shaped plates, and the distance between the second support plate 5 and the third support plate 6 and the circle containing the third mounting hole 101 is constant along the circumference, so that the second support plate 5 and the third support plate 6 are arranged at equal intervals on both sides of the circle.

[0086] The fifth support plate 8 is disposed on the inner side of the first support plate 2 to enhance the structural strength of the first support plate 2.

[0087] A first stiffener 9 is provided between the second support plate 5 and the fifth support plate 8. A stiffener can also be provided between the third support plate 6 and the first support plate 2 or between the third support plate 6 and the sixth support plate 13.

[0088] The second support plate 5, the third support plate 6, the fourth support plate 7, the fifth support plate 8, and the sixth support plate 13 are all vertically mounted on the mounting plate 1. Multiple second stiffening plates 14 are provided between the two sixth support plates 13. The multiple second stiffening plates 14 are arranged at intervals along the front-to-back direction. The second stiffening plates 14 are inclined on the mounting plate 1. The two ends of the second stiffening plates 14 located at the rear extend outwards to the outer side of the first support plate 2.

[0089] In order to meet the rigidity requirements of the sixth mounting base 18 at the tail for mounting the counterweight, a sixth support plate 13 is provided on the rear side of the third support plate 6, and the sixth support plate 13 extends directly to the bottom of the sixth mounting base 18 at the tail.

[0090] Stiffening plates are provided below both the first connecting structure 11 and the second connecting structure 12 used for installing the A-frame. For example, as Figure 3 As shown, two roughly triangular side plates are connected to both sides of the seventh support plate 24. These side plates are perpendicular to the seventh support plate 24. The first connecting structure 11 is mounted on the side plates. The seventh support plate 24 is vertically positioned between the front cover plate 301 and the rear cover plate 302. Ribs are provided between the seventh support plate 24 and the side plates, and between the seventh support plate 24 and the front cover plate 301.

[0091] like Figure 2 As shown, the side of the first connecting structure 11 is provided with a third stiffening plate 22.

[0092] The front end of mounting plate 1 is also provided with a third mounting seat 15 for mounting a slewing reducer. Cover plate 3 is provided with a fourth mounting seat 16 for mounting a luffing winch, a fifth mounting seat 17 for mounting a V-frame lifting cylinder, and a sixth mounting seat 18 for mounting a counterweight. The sixth mounting seat 18 is located at the rear end of the rear cover plate 302. The fourth mounting seat 16 is located behind the second mounting seat 10, and the fifth mounting seat 17 is located on both sides of the fourth mounting seat 16. The second connecting structure 12 is located between the fourth mounting seat 16 and the sixth mounting seat 18.

[0093] The pipeline channels on the turntable mounting structure are all designed with circular or oblong openings to avoid stress concentration. For example... Figure 2 The first through hole 20 shown is a round hole, and the second through hole 21 is an oblong hole.

[0094] The front end of the mounting plate 1 is provided with an oil passage 23 that connects to the oil drain pipe of the rotary reducer.

[0095] The turntable mounting structure provided in this embodiment has a strong load-bearing capacity and can withstand the force brought by at least two lifting winches, enabling the dynamic compaction machine to adapt to two or more construction methods. One machine can realize multiple construction methods, reducing the types and quantities of dynamic compaction machines that customers need to purchase and improving the economic efficiency of the purchased dynamic compaction machines.

[0096] Based on the above-described rotary table mounting structure for a dynamic compaction machine, the present invention also proposes a dynamic compaction machine that includes the aforementioned rotary table mounting structure.

[0097] The positive technical effects of the turntable mounting structure of the dynamic compaction machine in the above embodiments are also applicable to the dynamic compaction machine, and will not be repeated here.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can still be made to some technical features without departing from the principle of the present invention, and such modifications and equivalent substitutions should all be covered within the scope of the technical solutions claimed in the present invention.
