配重提升装置、 配重提升结构和提升配重的方法  Counterweight lifting device, counterweight lifting structure and method for lifting weight
技术领域  Technical field
本发明涉及起重机， 具体地， 涉及一种配重提升装置、 配重提升结构 和提升配重的方法。 背景技术  The present invention relates to a crane, and in particular to a weight lifting device, a weight lifting structure, and a method of lifting a weight. Background technique
配重是起重机的主要结构件， 配重的重量对起重机的稳定性和起重性 能有很大的影响。 现有技术中， 不使用配重 10时， 通常将配重 10放置在 基础面 （例如起重机的车架平面） 上； 需要装配配重时， 如图 1 所示， 通 常使用安装在起重机的转台 30尾部的配重提升液压缸 20来提升配重 10， 配重提升液压缸 20包括缸筒 21和活塞杆 22。具体地， 配重 10的顶部具有 腰孔， 提升配重 10时， 将转台 30转动到腰孔上方使得配重提升液压缸 20 的活塞杆 22的端部能够伸入腰孔的位置（例如稍稍偏离腰孔的中心线的位 置）， 然后伸出活塞杆 22， 使活塞杆 22的端部伸入腰孔； 然后将转台 30转 动预定角度 （例如转动到使得转台 30平行于腰孔中心线的位置）， 使得活 塞杆 22的端部无法穿过腰孔， 然后收缩活塞杆 22以使活塞杆 22的端部卡 在腰孔下方， 从而完成配重提升液压缸 20和配重 10的固定； 最后收缩活 塞杆 22以提升配重 10。  The counterweight is the main structural part of the crane. The weight of the counterweight has a great influence on the stability and lifting performance of the crane. In the prior art, when the counterweight 10 is not used, the counterweight 10 is usually placed on the base surface (for example, the frame plane of the crane); when the counterweight needs to be assembled, as shown in Fig. 1, the turntable mounted on the crane is usually used. The counterweight lifting hydraulic cylinder 20 of the 30 rear end lifts the counterweight 10, and the counterweight lifting hydraulic cylinder 20 includes a cylinder 21 and a piston rod 22. Specifically, the top of the counterweight 10 has a waist hole, and when the weight 10 is lifted, the turntable 30 is rotated above the waist hole so that the end of the piston rod 22 of the counterweight lifting hydraulic cylinder 20 can reach the position of the waist hole (for example, slightly Deviating from the centerline of the waist hole), then extending the piston rod 22 to extend the end of the piston rod 22 into the waist hole; then rotating the turntable 30 by a predetermined angle (for example, rotating so that the turntable 30 is parallel to the centerline of the waist hole) Position) that the end of the piston rod 22 cannot pass through the waist hole, and then the piston rod 22 is contracted to cause the end of the piston rod 22 to be caught under the waist hole, thereby completing the fixing of the weight lifting hydraulic cylinder 20 and the weight 10; The piston rod 22 is finally contracted to raise the weight 10.
对于吨位较小的起重机来说， 可以采用上述方式， 例如可以在转台 30 尾部两侧安装两个配重提升液压缸 20， 来实现配重 10的装卸。但随着起重 机吨位的增大， 配重 10的尺寸增大。 为提升配重 10， 配重提升液压缸 20 的活塞杆 22的延伸方向应尽可能靠近配重 10的重力线或与该重力线重合。 由于配重 10的尺寸增大， 导致其重力线到转台 30的尾部的距离以及该重 力线到配重 10的回转中心的距离 （即回转半径） 增大， 增大的距离无法通 过加长转台 30的长度来弥补， 因为这将导致整车的行驶重量增加。 另外， 转台 30尾部下端面与车架距离较近， 限制了配重 10重量 （即配重块的数 量、 高度） 的增加。 For a crane with a small tonnage, the above method can be adopted. For example, two weight lifting hydraulic cylinders 20 can be installed on both sides of the tail of the turntable 30 to realize the loading and unloading of the weight 10. However, as the tonnage of the crane increases, the size of the counterweight 10 increases. To lift the counterweight 10, the direction of extension of the piston rod 22 of the counterweight lifting hydraulic cylinder 20 should be as close as possible to or coincident with the line of gravity of the counterweight 10. As the size of the counterweight 10 increases, the distance from the gravity line to the tail of the turntable 30 and the distance from the gravity line to the center of rotation of the counterweight 10 (ie, the radius of gyration) increase, and the increased distance cannot pass through the extended turntable 30. The length is compensated for, as this will result in an increase in the driving weight of the entire vehicle. In addition, The lower end of the tail end of the turntable 30 is closer to the frame, which limits the weight of the counterweight 10 (i.e., the number and height of the weights).
因此， 现有技术中存在难以提升重量较大的配重的问题。 发明内容  Therefore, there is a problem in the prior art that it is difficult to increase the weight of the weight. Summary of the invention

通过接合第一安装结构和第二安装结构， 配重架 40能够连接到配重液 压缸 20。 换言之， 当第一安装结构和第二安装结构接合时， 配重液压缸 20 的两端分别连接配重 10和配重架 40，当配重液压缸 20的活塞杆 22伸缩时， 将根据配重液压缸 20的两端的固定情况而带动配重 10或配重架 40移动。 也就是说， 当配重液压缸 20的连接配重 10的一端固定时， 活塞杆 22的伸 缩将带动配重架 40升降， 也就是通过配重液压缸 20对配重架 40提供起吊 功能， 便于配重架 40安装到转台 30的操作； 当配重液压缸 20的连接配重 架 40的一端固定时， 活塞杆 22的伸缩将带动配重 10升降， 从而能够提升 配重 10。 The counterweight frame 40 can be coupled to the counterweight hydraulic cylinder 20 by engaging the first mounting structure and the second mounting structure. In other words, when the first mounting structure and the second mounting structure are engaged, the two ends of the counterweight hydraulic cylinder 20 are respectively connected with the counterweight 10 and the counterweight frame 40, and when the piston rod 22 of the counterweight hydraulic cylinder 20 is expanded and contracted, The weight of both ends of the heavy hydraulic cylinder 20 drives the weight 10 or the weight frame 40 to move. That is, when one end of the connection weight 10 of the counterweight hydraulic cylinder 20 is fixed, the extension of the piston rod 22 The contraction will drive the counterweight frame 40 up and down, that is, the weighting cylinder 40 provides a lifting function to the weighting frame 40, facilitating the operation of the weighting frame 40 to the turntable 30; when the counterweight hydraulic cylinder 20 is connected to the weighting frame 40 When one end is fixed, the expansion and contraction of the piston rod 22 will drive the counterweight 10 up and down, thereby lifting the weight 10.
其中， 配重 10可以采用适当的结构， 以便连接到配重液压缸 20的一 端。 优选地， 如图 2所示， 所述配重 10可以包括依次固定的底配重块 11、 基础配重块 12和上配重块 13，所述底配重块 11与所述配重液压缸 20的一 端固定连接， 所述配重液压缸 20的另一端穿过所述基础配重块 12， 所述上 配重块 13为多个分为两列对称布置在所述基础配重块 12上， 两列上配重 块 13之间的距离 d允许所述配重液压缸 20的另一端伸入其中， 所述第二 安装结构设置在所述配重液压缸 20的另一端上。  Here, the counterweight 10 may be of a suitable structure for connection to one end of the counterweight hydraulic cylinder 20.

通过将配重液压缸 20的另一端伸入到两列上配重块 13之间， 配重液 压缸 20的另一端能够在两列上配重块 13之间伸缩。 当活塞杆 22的长度足 够长时， 可以使配重液压缸 20的另一端伸出到上配重块 13的上方， 从而 在连接配重架 40后使配重架 40在上配重块 13上方调节高度。 在本发明的 优选实施方式中， 两列上配重块 13之间的距离 d可以允许所述配重架 40 放入其中。 通过这种布置， 配重架 40能够放入两列上配重块 13之间的位 置， 活塞杆 22可以具有较短的长度， 有利于配重架 40连接到配重液压缸 20的另一端的第二安装结构， 并且能够提高整体稳定性。  By extending the other end of the counterweight hydraulic cylinder 20 between the weights 13 on the two rows, the other end of the counterweight hydraulic cylinder 20 can be expanded and contracted between the weights 13 on the two rows. When the length of the piston rod 22 is sufficiently long, the other end of the counterweight hydraulic cylinder 20 can be extended above the upper weight 13 so that the weight frame 40 is placed on the upper weight 13 after the weight frame 40 is attached. Adjust the height above. In a preferred embodiment of the invention, the distance d between the weights 13 on the two rows allows the weight frame 40 to be placed therein. With this arrangement, the counterweight frame 40 can be placed in a position between the weights 13 on the two rows, and the piston rod 22 can have a shorter length, which facilitates the connection of the counterweight frame 40 to the other end of the counterweight hydraulic cylinder 20.
