Referring now to fig. 1-12, embodiments of the present invention will be described. It is to be understood that the following description is only exemplary of the present invention and is not intended to limit the present invention in any way. In the drawings, fig. 1-9 illustrate the structure of a first counterweight group in a counterweight assembly for a work machine; FIG. 10 illustrates the configuration of a second counterweight group in a counterweight assembly for a work machine; fig. 11 and 12 show schematic radii of gyration for a first set of formulations and a second set of formulations, respectively.

As shown in fig. 1-10, a first aspect of the present disclosure provides a work machine counterweight assembly 100. The work machine counterweight assembly 100 may generally include a first counterweight group 102 and a second counterweight group 104.

Specifically, during actual use, the first mating group 102 and the second mating group 104 may be removably coupled to the primary platform of the work machine in an alternative manner. In other words, one of the matching sets can be selected according to actual use needs or scene needs, and the selected matching set is assembled on the main platform of the working machine for working. In an embodiment of the present invention, the thickness of the first matching unit 102 may be smaller than the thickness of the second matching unit 104.

Specifically, since the thickness of the first matching unit 102 may be smaller than that of the second matching unit 104, after assembly, the radius of gyration of the first matching unit 102 may be smaller than that of the second matching unit 104, so that the method can be applied to a scene with limited space on a construction site. In other words, when the space of the construction site is limited, the first counterweight group 102 having a relatively small radius of gyration may be used directly.

Further, the first counterweight group 102 may include a first counterweight and a second counterweight. Specifically, the second counterweight is detachably mountable on the outside of the first counterweight. In actual use, when the first counterweight group 102 is applied, the second counterweight may be removed from the first counterweight if further reduction in radius of gyration is desired.

Therefore, the embodiment of the present invention provides a counterweight assembly 100 for a working machine, which can adjust multiple turning radii, and can be selectively used under different application scenarios.

Further in an embodiment of the present invention, the packing density of the first set of formulations 102 may be greater than the packing density of the second set of formulations 104. Specifically, in the field of work machines, if the masses of the first matching unit 102 and the second matching unit 104 are the same or similar and it is required that the thickness of one of the matching units (i.e., the first matching unit 102) is smaller, one of the ways is to set the internal filling density of the first matching unit 102 to be greater than that of the second matching unit 104. For example, the iron content in the first recombinant vector 102 may be set to be greater than the iron content in the second recombinant vector 104. In this way, the effect of having two sets of weights of the same or similar mass to provide the same or similar load carrying capacity, and one set of weights of a smaller thickness, can be achieved.

In this embodiment, the second formulation group 104 is relatively low cost during practical use due to its relatively low packing density. In other words, an appropriate weight set can be further selected for multi-scenario applications as needed. For example, in an economically developed area, especially in a super-large city, because the space of a construction site is limited, the construction site has strong requirements on a working machine with a smaller turning radius, and the first matching unit 102 can be selected for use; in less economically developed areas, where the primary customer demand is low cost and there is no requirement for the radius of gyration, the second partner group 104 may be selected for use.

Embodiments of the first recombinant vector 102 and the second recombinant vector 104 of the present invention are described below with reference to the drawings.

In an alternative embodiment, the first counterweight may include at least one counterweight disposed along the height of work machine counterweight assembly 100, and the second counterweight may include at least one counterweight removably mounted outside of the first counterweight. In other words, the number of the first balance weights and the second balance weights is not limited to any specific number, and may be set as needed. The present invention will be described below with the first weight comprising a first weight block 106 and a second weight block 108, and the second weight comprising a third weight block 110 as an example. It should be understood, however, that the following are only exemplary embodiments.

As shown in fig. 1 to 9, in an embodiment of the present invention, the first weight of the first matching set 102 may include at least a first weight block 106 and a second weight block 108, and the second weight of the first matching set 102 may include at least a third weight block 110.

Specifically, the first weight 106 can be detachably connected to the main platform, and when the first weight assembly 102 needs to be used, the first weight 106 is installed on the main platform. In addition, the second weight block 108 is detachably assembled on the top of the first weight block 106, the third weight block 110 may be located outside the first weight block 106 and the second weight block 108, and the third weight block 110 may be hung on the second weight block 108 and detachably connected to the first weight block 106, thereby forming an integral structure of the first assembly set 102 as shown in fig. 1. The assembly process of the first assembly set 102 is illustrated in fig. 2 to 9, and will be described in detail below with reference to the accompanying drawings.

As shown in fig. 2 and 3, in an embodiment of the present invention, a first hanging boss 112 may be disposed on the top of the first weight block 106, and a first pin 114 may be disposed on the first hanging boss 112 in a penetrating manner. In actual assembly, the first pin 114 can be hooked to a main platform ear plate 202 located on the main platform 200.

Further, as shown in fig. 4 and 5, a fixing rod 116 may be disposed on the second weight member 108. After the first weight block 106 is assembled, the second weight block 108 is installed on the first weight block 106, and then the fixing rod 116 penetrates from the top of the second weight block 108 and extends downward to be inserted on the first weight block 106, so as to assemble the first weight block 106 and the second weight block 108 together.

Next, as shown in fig. 6 and 7, after the second weight block 108 is assembled, a third weight block 110 may be assembled. Specifically, the top of the third weight member 110 may be provided with a second hanging boss 118, and the second hanging boss 118 may be provided with a second pin 120. Correspondingly, the top of the second weight member 108 may be provided with a hanging ear plate 122. In assembly, the second pin 120 may be hung on the hitch ear plate 122, and the third weight 110 and the first weight 106 may be connected together by a fastener 124 (e.g., a bolt), as shown in fig. 8 and 9.

It should be noted here that the above description of the first weight comprising the first weight block 106 and the second weight block 108 and the second weight comprising the third weight block 110 is only an illustrative embodiment of the present invention, and in other alternative embodiments, the first weight and the second weight may comprise different numbers of weight blocks.

As shown in fig. 10, in an embodiment of the present disclosure, the second counterweight group 104 may include a plurality of fourth counterweight blocks 126 stacked in sequence along the height direction of the work machine counterweight assembly 100. Specifically, the fourth weight block 126 at the bottom layer can be detachably connected to the main platform 200 when the second weight block 104 is needed. Meanwhile, the fourth weights 126 of two adjacent layers can be detachably inserted into each other through a guide post and a guide groove structure (not shown). Further, for the topmost fourth weight block 126, it may include a first weight monolith 128 and a second weight monolith 130 disposed adjacent to each other. Unlike the first counterweight group 102, the number of fourth counterweight blocks 126 can be directly increased or decreased for the second counterweight group 104 when it is necessary to adjust the load capacity, without a change in the radius of gyration.

In the actual operation process, the user can select the first matching set 102 and the second matching set 104 according to actual requirements. For the first matching group 102, the balancing weights are assembled in a front-back connection mode, the filling density is high, the turning radius is small, and the cost is relatively high; for the second matching group 104, the matching weight blocks are assembled in a vertical connection mode, so that the packing density is low, the turning radius is large, and the cost is low.

In addition, for the first counterweight group 102, the first counterweight 106 can be transported with the main platform, thereby reducing transportation cost. In addition, after the first balancing weight 106 is transported along with the main platform, only two balancing weights need to be installed, so that the time for assembling the balancing weights is shortened, and the efficiency is improved. In addition, the first counterweight group 102 and the second counterweight group 104 have higher universality, namely, the two counterweight groups are completely universal, and no additional main platform is required to be designed.

When the first mating set 102 is used, the assembly of the first weight 106, the second weight 108, and the third weight 110 may be performed as desired. For example, taking a working machine as an example of a crawler crane, when the crawler crane assembles three counterweights, the hoisting capacity of the crawler crane is the nominal rated load, namely when the crawler crane assembles three counterweights, the hoisting capacity of the crawler crane is 60 t; when the crawler crane assembles two counterweights (the first counterweight block 106 and the second counterweight block 108), the hoisting capacity is 30-60% of the nominal load, and the gyration radius is reduced by 5%; when a crawler crane assembles a counterweight (first counterweight 106), its lifting capacity is 10-30% of the nominal load. When the second matching unit 104 is used, the weight block is reduced in principle in accordance with the first matching unit 102, so that the hoisting capacity can be reduced without reducing the working radius.

Referring to fig. 11 and 12, the turning radii of two counterweight groups are compared, taking a 60t crawler crane as an example of the working machine:

the thickness of the first mating body 102 has two options, namely thickness A1 and thickness B1, corresponding to radius of gyration A2 and radius of gyration B2. Wherein, the thickness a1 corresponds to the situation that the first counterweight block 106, the second counterweight block 108 and the third counterweight block 110 are all assembled; the thickness B1 corresponds to the case of assembling the first weight 106 or assembling the first weight 106 and the second weight 108. For the second matching unit 104, the thickness, i.e., the thickness C1, corresponds to the radius of gyration C2. Wherein the radius of gyration C2 is greater than the radius of gyration a2 and the radius of gyration B2.

Further, for weight thickness comparison, thickness A1 is approximately 35% narrower than thickness C1, and thickness B1 is approximately 55% narrower than thickness C1. For the radius of gyration comparison, the radius of gyration a2 was about 10% less than the radius of gyration C2, and the radius of gyration B2 was about 15% less than the radius of gyration C2. For cost comparison, the first matching set 102 accounts for about 4.5% of the total cost, and the second matching set 104 accounts for about 0.7% of the total cost.

On the other hand, the embodiment of the utility model provides a still provides an operation machinery. The work machine may include a main platform and a work machine counterweight assembly 100 as described above. During assembly, the main platform may be provided with a main platform ear plate 202, and the first matching unit 102 and the second matching unit 104 may alternatively be detachably attached to the main platform ear plate 202.

It should be understood herein that while the work machine has been described above as a crawler crane, any other suitable work machine type may be included in the present disclosure. In other words, the type of work machine does not set any limit to the present invention. Further, the present invention provides a working machine having the above-described counterweight unit 100, and therefore having all the advantages described above.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
