[0038] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0039] The following will describe a counterweight and a construction machinery according to the present utility model with reference to the accompanying drawings.

[0040] As Figure 1 and Figure 2 shown, in this embodiment, a counterweight is proposed. The counterweight includes a counterweight box 1 and a partition main body 2. An object placement space is formed inside the counterweight box 1. The bottom end of the counterweight box 1 has a hanging component for hanging an external boom 10, and the outer periphery of the counterweight box 1 has a positioning component for stacking and connecting an external counterweight block 30. The partition main body 2 is arranged in the object placement space and includes a plurality of horizontal plates 21 and vertical plates 22. The plurality of horizontal plates 21 and the vertical plates 22 are arranged crosswise and divide the object placement space into a plurality of counterweight areas for storing fillers. The plurality of counterweight areas are independent of each other. Among them, the fillers are not limited to concrete plus iron ore, etc., and other substances with the same density can also be used.

[0041] In this embodiment, the partition main body 2 is arranged in the object placement space formed inside the counterweight box 1. The partition main body 2 is composed of a plurality of horizontal plates 21 and a plurality of vertical plates 22. The plurality of horizontal plates 21 and the plurality of vertical plates 22 are arranged crosswise and divide the object placement space into a plurality of counterweight areas for storing fillers, and fillers with different weights can be filled into the counterweight areas as needed. This solves the technical problem in the prior art that the production cost of the counterweight is high due to the use of solid iron casting. Moreover, a hanging component for hanging an external boom 10 is provided at the bottom end of the counterweight box 1, which is suitable for the working condition of hanging a boom at the bottom of the counterweight box 1. A positioning component for stacking and connecting an external counterweight block 30 is also provided on the outer periphery of the counterweight box 1, which is suitable for the working condition of cooperating with the counterweight box 1 to hang an external counterweight block 30. In addition, it can also be suitable for the working condition of a single counterweight hanging. Thus, the counterweight in this embodiment has good versatility and can be suitable for a variety of working conditions.

[0042] As Figure 1 and Figure 2As shown, in this embodiment, the hanging component includes a hanging ear plate 111 and a hanging pin 112. The number of hanging ear plates 111 is two and they are symmetrically arranged at the bottom end of the counterweight box 1. The hanging ear plate 111 is formed with a plug hole. The hanging pin 112 passes through the plug hole and connects the hanging ear plate 111 and the external boom 10. Wherein, there is a hanging gap between the hanging pin 112 and the bottom of the counterweight box 1. When the counterweight box 1 is used to connect the boom, the counterweight can be first connected to the luffing pulley block. A sling is also connected to the external boom 10. The sling passes through the hanging gap and surrounds the two hanging pins 112, and can stably hang the external boom 10 below the counterweight box 1, meeting the connection requirements of the external boom 10, without the need to additionally use an auxiliary crane to lift the boom, and at the same time ensuring the stability of the connection between the counterweight box 1 and the external boom 10. Through the cooperation of the hanging pin 112 and the sling, the connection of external booms 10 with different widths can be realized. Among them, the hanging pin 112 can be replaced with a shackle in the prior art.

[0043] In this embodiment, the extending direction of the hanging pin 112 is the same as the direction of the connecting shaft on the external boom 10, which is beneficial to extending the structural size of the hanging ear plate 111 in the width direction of the counterweight box 1, increasing the structural strength of the hanging ear plate 111, and avoiding the cracking of the hanging ear plate 111 caused by the excessive horizontal component force of the sling when the external boom 10 is hung on the hanging pin 112 due to the large width of the external boom 10. Preferably, the hanging ear plate 111 is integrally formed and connected to the counterweight box 1, improving the structural strength of the hanging ear plate 111 and making the hanging of the external boom 10 by the hanging ear plate 111 more stable.

[0044] As Figure 1 、 Figure 2 and Figure 4 shown, in this embodiment, a locking hole is further formed in the end of the hanging pin 112 along the radial direction. A limit locking pin 113 is inserted into the locking hole, and the limit locking pin 113 is used to limit and lock the hanging ear plate 111 and the external boom 10. Through the cooperation of the limit locking pin 113 and the locking hole, the locking of the hanging ear plate 111 and the external boom 10 is realized, so that the hanging pin 112 can be detachably replaced from the plug hole, facilitating the maintenance and replacement of the hanging pin 112.

[0045] As Figure 1 and Figure 2As shown, in this embodiment, the counterweight box 1 includes a first sealing plate 12 and a second sealing plate 13 arranged in parallel and spaced apart, and the positioning assembly includes a positioning protrusion 141 extending from the outer wall of the second sealing plate 13 toward the counterweight area, and the positioning protrusion 141 is used to position and cooperate with the external counterweight block 30. In this embodiment, two positioning protrusions 141 are symmetrically arranged in the middle of the second sealing plate 13, and a positioning space is formed in the positioning protrusion 141, which can be plugged and matched with the positioning column on the external counterweight block 30. When the counterweight box 1 is used as a counterweight for a super crane, the counterweight box 1 is placed at the top of the external counterweight block 30. At this time, the first sealing plate 12 is located above the second sealing plate 13. The positioning protrusion 141 assists the counterweight box 1 to be placed in the correct position, so that the positioning column extends into the positioning space, and the counterweight box 1 is fixed to the external counterweight block 30. Then, multiple external counterweight blocks 30 are connected and lifted with the counterweight box 1 by a sling, which plays the role of counterweight pressure, thereby reducing the use of an external counterweight block 30 of the same weight. When the ballast box 1 is used as a vehicle body counterweight, the ballast box 1 only needs to be placed on the top of the external ballast block 30 , and the positioning protrusion 141 is used to assist in ensuring that the ballast box 1 is placed in the correct position.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the positioning assembly further includes a plurality of positioning lugs 142 for being hooked by the external pulley block, and the plurality of positioning lugs 142 are symmetrically arranged along a side of the first sealing plate 12 away from the second sealing plate 13. Figure 5 As shown, when the counterweight box 1 is used as a counterweight block of a super crane, the counterweight box 1 can be lifted by passing a sling through the positioning lug plate 142. A plurality of positioning lug plates 142 are provided and a sling is passed through, which can ensure good lifting stability of the counterweight box 1. The positioning lug plates 142 can be replaced by lifting rings or lifting piles, which can play the role of matching the sling.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, no matter the counterweight box 1 is used as a super crane counterweight piece or a super crane counterweight block, a plurality of buffer pads 131 are arranged at intervals on the side of the second closing plate 13 facing away from the first closing plate 12, which can reduce the impact received by the counterweight box 1 during the docking process with the external counterweight block 30, and avoid damage and bump caused by hard contact between the counterweight box 1 and the external counterweight block 30.

[0048] like Figure 1 and Figure 2As shown, in this embodiment, welding protrusions 211 are provided at the side ends of the cross plate 21 facing the first sealing plate 12 and the second sealing plate 13. Positioning grooves are provided at the positions of the first sealing plate 12 and the second sealing plate 13 corresponding to the welding protrusions 211. The welding protrusions 211 are in limiting and locking cooperation with the positioning grooves, playing a role in assisting positioning, and can quickly realize the combined splicing of the cross plate 21 with the first sealing plate 12 and the second sealing plate 13, facilitating the subsequent welding of the cross plate 21 with the first sealing plate 12 and the second sealing plate 13.

[0049] As Figure 3 As shown, in this embodiment, the counterweight box 1 further includes side plates 15 arranged in parallel at intervals. Hanging lugs 151 are provided at the top ends of the side plates 15. Hanging holes for connecting an external luffing pull plate 20 are provided on the hanging lugs 151. A reinforcing ring 152 is sleeved on the outer periphery of the top wall of the hanging holes. The reinforcing ring 152 and the hanging holes are in sealing cooperation. Under the working condition where the counterweight is used as a counterweight, the hanging holes at the top ends of the side plates 15 usually need to be cooperatively hung with the external luffing pull plate 20 arranged above the counterweight box 1, and the hanging holes are prone to wear. Therefore, a reinforcing ring 152 is sleeved on the outer periphery of the top wall of the hanging holes to play a role in protecting the hanging holes and extending the service life of the counterweight box 1. The counterweight box 1 is provided with a top plate and a bottom plate in the up-down direction. The top plate, the bottom plate, the two side plates 15, the first sealing plate 12, and the second sealing plate 13 jointly enclose and weld to form the counterweight box 1. In the actual manufacture of the counterweight box 1, a storage space is first formed by welding the top plate, the bottom plate, the two side plates 15, and the second sealing plate 13, and then the storage space is partitioned into multiple independent counterweight areas by the cross plate 21 and the vertical plate 22. Fillers are filled into the counterweight areas, and then the counterweight box 1 is welded and closed by the first sealing plate 12. Of course, the welding process of the counterweight box 1 can be adjusted according to actual needs. Preferably, a reinforcing ring 152 is also provided in sealing cooperation with the plugging holes.

[0050] In this embodiment, a construction machinery is proposed, including the counterweight as described above. Since the construction machinery adopts all the embodiments of the counterweight, it also has all the beneficial effects brought by the counterweight, which will not be elaborated in detail here. In one embodiment, the construction machinery is a crane. In other embodiments, the counterweight can also be used in other construction machinery that needs to be equipped with a counterweight.
