Description

Technical Field

[0001] The utility model relates to a storage and transfer tooling for a rotary reducer for an ultra-large hydraulic excavator, belonging to the technical field of ultra-large hydraulic excavators. Background Art

[0002] The slewing reducer for super-large hydraulic excavators is large in mass and volume. It is usually transported and stored with disposable tooling made of solid wood or synthetic wood. The assembly of the slewing reducer is divided into two stages: sub-assembly and hoisting. The wooden tooling needs to be disassembled before sub-assembly. Only after disassembly can the accessories of the slewing reducer be assembled on the main body of the reducer. During the hoisting stage, the slewing reducer needs to be lifted with the help of lifting rings and lifting equipment, and then hoisted into the turntable reducer mounting seat for assembly. Generally, multiple models of super-large hydraulic excavators are assembled at the same time at the assembly site, and the matching multi-model slewing reducers are also transported, stored, sub-assembled and hoisted at the assembly site at the same time. The appearance, weight and degree of sub-assembly of different models of slewing reducers vary greatly.

[0003] During the above-mentioned slewing reducer assembly process, the slewing reducer sub-assembly needs to be carried out after the upper part of the wooden tooling is disassembled. Disassembly causes the tooling to lose its protective ability and no longer meets the transportation and storage requirements. The wooden tooling cannot be restored and used on the assembled slewing reducer, and there is no plug-in structure at the bottom and no lifting structure at the top. It cannot be directly transported by forklifts and cranes. After disassembly, it can only support the slewing reducer in place and wait for sub-assembly and lifting. The vertical support of the wooden tooling is poor, and the slewing reducer fixed in the wooden tooling can only be stored in a single layer and cannot be stacked. The structure of the wooden tooling can only accommodate slewing reducers of corresponding models, and different models are incompatible with each other.

[0004] The wooden tooling that comes with the slewing reducer is a one-time transfer tooling designed and manufactured by the reducer manufacturer to meet the product shipping needs. Its structural design is only for the corresponding model of slewing reducer and is incompatible with each other; the wooden structure is difficult to support a 1 to 2 ton slewing reducer in the vertical direction, so it cannot be stored in multiple layers. During the assembly of the reducer, the wooden tooling needs to be disassembled to make it lose its protective ability. There is no plug-in structure at the bottom of the wooden tooling and no hoisting structure at the top, which makes it not flexible enough for transportation and storage at the assembly site. Summary of the invention

[0005] In view of the deficiencies of the prior art, the utility model provides a storage and transportation tooling for a slewing reducer for an ultra-large hydraulic excavator, which solves the transportation and storage problems of ultra-large slewing reducers of different models at the assembly site, and provides more standardized tooling protection, better tooling versatility, and more convenient on-site transportation and storage processes during the assembly of the slewing reducer. The tooling can be compatible with ultra-large slewing reducers of different models on site, meeting the on-site assembly requirements of multi-layer storage and on-demand retrieval.

[0006] The utility model is realized according to the following technical solutions:

[0007] A storage and transfer tooling for a swing speed reducer of an extra-large hydraulic excavator, comprising:

[0008] A main frame, which is a rigid frame and has at least one storage space for storing the swing speed reducer;

[0009] Limit brackets of multiple models, which are used to match swing speed reducers of different models. The limit brackets for pre-storing the swing speed reducer are placed in the storage space of the main frame. The swing speed reducer is gradually hoisted into the storage space of the main frame with its gear facing vertically downward until the flange protruding from the swing speed reducer is placed on the limit bracket.

[0010] In some embodiments, the main frame includes a bottom frame, an annular side frame vertically extending upward around the periphery of the bottom frame, and at least one support seat located inside the annular side frame and above the bottom frame; one support seat corresponds to one storage space, and the limit bracket is placed on the support seat.

[0011] In some embodiments, the main frame further includes at least one inner frame, which is used to divide the accommodation space formed by the bottom frame and the annular side frame into multiple storage spaces, so that the main frame can store at least two swing speed reducers.

[0012] In some embodiments, at least one hanging component capable of simultaneously hanging multiple limit brackets stacked one on top of the other in the front and back directions is provided on the annular side frame.

[0013] In some embodiments, the hanging component is composed of a hook above and a limit plate below; the multiple limit brackets are stacked and hung on the hook in the front and back directions, and the lower parts of the multiple limit brackets are located in the L-shaped limit plate. When the storage and transfer tooling is hoisted or transferred, the limit plate is used to prevent the limit brackets from shaking or detaching from the hook.

[0014] In some embodiments, limit pins are fixed at the tops of the columns at the four corners of the annular side frame, and limit holes are provided at the bottoms of the columns at the four corners of the annular side frame. When multiple storage and transfer toolings are stacked one on top of the other, adjacent two storage and transfer toolings are positioned and connected by inserting the limit pins into the limit holes.

[0015] In some embodiments, lifting lugs are fixed on the columns at the four corners of the annular side frame for hoisting the storage and transfer tooling; a forklift limit frame is fixed on the bottom frame for forklifting the storage and transfer tooling.

[0016] In some embodiments, both the limit bracket and the support base are square frames, and the limit bracket and the support base are overlapped with each other in a manner that their sides are parallel, so as to maximize the contact between the limit bracket and the support base.

[0017] In some embodiments, when the size of the limit bracket Ⅰ for pre-storing the slewing speed reducer is smaller than that of the support base, resulting in the inability of the limit bracket Ⅰ to be overlapped on the support base, N limit brackets Ⅱ, each of which is larger than the limit bracket Ⅰ and has a gradually increasing size from top to bottom, are stacked between the limit bracket Ⅰ and the support base, where N is an integer not less than 1.

[0018] In some embodiments, a lifting lug is fixed at each of the four corners of the limit bracket for lifting the limit bracket; a shock pad is fixed on the upper surface of each of the four sides of the limit bracket by a plurality of countersunk head screws.

[0033] It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present utility model in any way, but to illustrate the concept of the present utility model to those skilled in the art by referring to specific embodiments. Specific embodiments

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0035] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0036] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] As Figure 1 , Figure 2 , Figure 3 shown, a storage and transfer tooling for a swing speed reducer of an extra-large hydraulic excavator includes a main frame 1 and various types of limiting brackets 2, 3, 4, 5; the main frame 1 is a rigid frame and has at least one storage space for storing the swing speed reducer 9; the various types of limiting brackets 2, 3, 4, 5 are used to match different models of swing speed reducers 9. The limiting bracket that has been matched with the swing speed reducer 9 to be pre-stored is placed in the storage space of the main frame 1. The swing speed reducer 9 is gradually hoisted into the storage space of the main frame 1 with its gear facing vertically downward until the flange of the swing speed reducer 9 protruding outwards is placed on the limiting bracket. The technical solution of the present utility model mainly solves the requirements for the transfer and storage of different models of extra-large swing speed reducers at the assembly site, provides more standardized tooling protection, better tooling versatility, and a more convenient on-site transfer and storage process during the assembly of the swing speed reducer. By using replaceable limiting brackets, the problem that different models of swing speed reducers cannot be transferred and stored in the same tooling is solved by replacing the limiting brackets.

[0038] The following further describes the above-mentioned main frame.

[0039] As Figure 4 , Figure 5 , Figure 6 shown, the main frame 1 includes a bottom frame 101, an annular side frame 102 vertically extending upwards around the periphery of the bottom frame 101, and at least one support seat 103 located inside the annular side frame 102 and above the bottom frame 101; one support seat 103 corresponds to one storage space, and the limiting brackets 2, 3, 4, 5 are placed on the support seat 103.

[0040] A further solution is that, as Figure 4 , Figure 5 , Figure 6 shown, the main frame 1 further includes at least one inner frame 104, which is used to divide the accommodation space formed by the bottom frame 101 and the annular side frame 102 into multiple storage spaces, so that the main frame 1 can store at least two swing speed reducers 9.

[0041] A further solution is that, as Figure 4 ,Figure 5 , Figure 6 As shown in Figure 6 , at least one hanging component capable of simultaneously hanging a plurality of limiting brackets 2, 3, 4, 5 stacked one on top of the other in the front-rear direction is provided on the annular side frame 102.

[0042] Preferably, as Figure 4 , Figure 5 , Figure 6 shown, the hanging component is composed of a hook 105 above and a limiting plate 106 below; a plurality of limiting brackets 2, 3, 4, 5 are stacked one on top of the other in the front-rear direction and hung on the hook 105, and the lower parts of the plurality of limiting brackets 2, 3, 4, 5 are located in the L-shaped limiting plate 106. When the storage and transfer tooling is hoisted or transferred, the limiting plate 106 is used to prevent the limiting brackets 2, 3, 4, 5 from shaking or detaching from the hook 105.

[0043] Furthermore, as Figure 4 , Figure 5 , Figure 6 shown, limit pins 107 are fixed to the tops of the columns at the four corners in the annular side frame 102, and limit holes 110 are provided at the bottoms of the columns at the four corners in the annular side frame 102. When a plurality of storage and transfer toolings are stacked one on top of the other, adjacent two storage and transfer toolings are positioned and connected by inserting the limit pins 107 into the limit holes 110.

[0044] Furthermore, as Figure 4 , Figure 5 , Figure 6 shown, lifting lugs 108 are fixed to the columns at the four corners in the annular side frame 102 for hoisting the storage and transfer tooling; a forklift limiting frame 109 is fixed to the bottom frame 101 for forklifting the storage and transfer tooling.

[0045] It should be noted that the main frame 1 is welded by rectangular tubes, with good protection performance, strong support, and good durability. The design of the main frame 1 facilitates the in-workpiece sub-assembly operation of the slewing reducer 9. Various types of limiting brackets 2, 3, 4, 5 can be used in combination or hung on the side hook 105, making it convenient for storage and retrieval.

[0046] The above-mentioned limiting brackets are further described below.

[0047] As Figure 7 shown, the limiting brackets 2, 3, 4, 5 and the support base 103 are all square frames, and the limiting brackets 2, 3, 4, 5 and the support base 103 are overlapped in a side-to-side parallel manner, so as to maximize the contact between the limiting brackets 2, 3, 4, 5 and the support base 103. Since each slewing reducer 9 weighs 1 ton - 2 tons, only when the limiting brackets 2, 3, 4, 5 contact the support base 103 as much as possible can the stability of the slewing reducer 9 assembled in the limiting brackets 2, 3, 4, 5 be ensured.

[0048] In a further solution, when the size of the limit bracket I pre-stored for matching the slewing speed reducer 9 is smaller than the size of the support seat 103, resulting in the inability of the limit bracket I to overlap on the support seat 103, N limit brackets II, which are all larger than the limit bracket I in size and gradually increase in size from top to bottom, are stacked between the limit bracket I and the support seat 103, where N is an integer not less than 1.

[0049] In a further solution, as Figure 7 shown, a lifting lug 8 is fixed at each of the four corners of the limit brackets 2, 3, 4, and 5 to realize the lifting of the limit brackets 2, 3, 4, and 5; a shock pad 7 is fixed on the upper surfaces of the four sides of the limit brackets 2, 3, 4, and 5 through a plurality of countersunk head screws 6.

[0050] In a preferred solution, the shock pad 7 is made of a polyurethane pad. Polyurethane is the abbreviation of polyisocyanate, and is also often called polyurethane elastomer. Its molecular chain contains a urethane structure and is an organic polymer material with properties between plastics and rubbers. Due to its excellent mechanical properties, good resistance to climate, chemical corrosion, fatigue, wear, and high impact resistance, polyurethane is one of the most commonly used polymer materials in life and industry. Its main products include polyurethane foam, polyurethane elastomer, polyurethane adhesive, polyurethane coating, etc.

[0051] It should be noted that Figure 7 only a preferred embodiment of the limit bracket is given, and the limit bracket is not limited to the structure in this embodiment. Corresponding local modifications can be made during actual use. However, no matter how it is modified, the limit bracket is a square frame, and a shock pad is installed on the square frame.

[0052] Working process: As Figure 8 shown, when using a certain model of slewing speed reducer 9, first place the corresponding limit bracket 2 of this model on the support seat 103 in the main body frame 1, and lift the slewing speed reducer 9 into the limit bracket 2 in the main body frame 1 for sub-assembly. The temporarily unused limit brackets 3, 4, and 5 can be hung on the hook 105 on one side of the main body frame 1.

[0053] When the slewing speed reducer 9 needs to be transported, a forklift can insert the fork arms into the forklift limit frame 109 at the bottom of the main body frame 1 for fork loading and transportation, or a lifting tool can be used to connect the lifting lugs 108 at the four corners of the upper part of the main body frame 1 for lifting. When it is necessary to stack two layers up and down, with the assistance of a forklift or a lifting tool, the top limit pin 107 and the bottom limit hole 110 of the upper and lower main body frames 1 can be inserted up and down to make the stacked storage more secure.

[0054] The utility model realizes the compatible storage and transfer of various types of slewing reducers supporting large-sized hydraulic excavators of multiple models on site by using a set of tooling structures.

[0055] The tooling is welded by rectangular pipes, with good protection performance, strong support and good durability.

[0056] The main frame design of the tooling facilitates the sub-assembly operation of the slewing reducer in the tooling. Various types of limit brackets can be used in combination or hung on the side hooks for convenient access.

[0057] Limit pins are welded to the tops of the four corner columns of the main frame of the tooling, and limit holes are provided at the bottoms. When two toolings are stacked on top of each other, the limit pins are inserted into the limit holes to achieve firm stacking.

[0058] The forklift limit at the bottom of the tooling and the lifting lugs on the four corner columns of the tooling can realize the lifting and forklifting of the tooling, facilitating the transfer and temporary storage of the slewing reducer during the assembly process.

[0059] In summary, the utility model realizes the flexible transfer, multi-model compatible sub-assembly, multi-model compatible storage and multi-layer stacking of the slewing reducer for large-sized hydraulic excavators, improves the flexibility of assembly, standardizes the assembly process, enhances the protection ability, increases the safety of the assembly of large-sized slewing reducers, and reduces the occupation of the assembly site.

However, it can be understood that the embodiments of the utility model can be practiced without these specific details. In some instances, well-known methods, structures and technologies are not shown in detail so as not to obscure the understanding of this specification.

For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by this application.
