起重机的支脚盘安装在活动支腿的垂直油缸的底部, 形成起重机作业 时支腿与地面的接触部件。 由于起重机自身的重量和起吊的重物的重量都 通过支脚盘传递到地面, 因此支脚盘承受很大的支反力。 特别是在大吨位、 超大吨位的起重机中, 为了使支脚盘能够承受更大的荷载, 通常将支脚盘 设置为较大的尺寸。  The foot plate of the crane is mounted on the bottom of the vertical cylinder of the movable leg to form a contact part of the leg with the ground during crane operation. Since the weight of the crane itself and the weight of the lifting weight are transmitted to the ground through the foot plate, the foot plate is subjected to a large reaction force. Especially in large tonnage, oversized tonnage cranes, in order to allow the foot plate to withstand larger loads, the foot plate is usually set to a larger size.
附图 1 中所示的是现有技术中的典型的支脚盘的纵截面图。 支脚盘的 顶部为球座 1, 球座 1的顶面具有与垂直油缸的球头相匹配的球形槽。球座 1的底部支撑有底盘 2。 底盘 2具有明显大于球座 1的支撑面积, 以保证支 脚盘的支撑稳定性。 支脚盘的定位基本采用人工和辅助起升装置相配合的 移位对正方式, 并且为了能够一次性起吊通常将支脚盘设置成一体结构。 但是, 如上所述在大吨位、 超大吨位的起重机中, 随着支脚盘的尺寸的增 大, 其重量也随之增大。 这样, 现有技术中的支脚盘结构就存在难以快速 搬运和就位的缺陷, 从而影响了起重机的工作效率。 发明内容  Shown in Figure 1 is a longitudinal cross-sectional view of a typical leg disk of the prior art. The top of the foot plate is a ball seat. The top surface of the ball seat 1 has a spherical groove that matches the ball end of the vertical cylinder. The bottom of the tee 1 is supported by a chassis 2. The chassis 2 has a support area that is significantly larger than the seat 1 to ensure the support stability of the support plate. The positioning of the foot plates is basically a displacement alignment method in which the manual and auxiliary lifting devices are matched, and the foot plates are usually arranged in a unitary structure in order to be able to be lifted at one time. However, as described above, in a large tonnage, super large tonnage crane, as the size of the foot plate increases, the weight thereof also increases. Thus, the prior art foot tray structure has the drawback that it is difficult to carry and position quickly, thereby affecting the working efficiency of the crane. Summary of the invention

That is, each of the splice members 20 is provided with a groove 201 and a bump 203, and the groove 201 on one splice member 20 can be mated with the bump 203 on the other splice member 20. Specifically, the groove 201 and the bump 203 are spaced apart along the edge of the splicing member 20. Wherein, in the cross section of the groove 201, the width S of the groove of the groove 201 is larger than the width T of the opening of the groove 11. That is, the shape of the cross section of the groove 201 is a shape in which the opening is contracted. Thereby, the groove 201 forms a chute having a limit function. The bump 203 includes a neck portion 2031 and a head portion 2033. The positional relationship between the neck portion 2031 and the head portion 2033 is set such that, with respect to the edge of the splicing member 20, the neck portion 2031 is adjacent to the rim, and the head portion 2033 is away from the rim. In other words, the neck 2031 is coupled between the rim of the splicing member 20 and the head 2033. Moreover, the size and shape of the neck 2031 of the bump 203 match the width of the opening of the groove 201, and the size and shape of the head 2033 of the bump 203 and the groove The width of the trough of 201 matches.
根据上述,将两个拼接件 20进行组装时,第一个拼接件 20的凸块 203 的头部 2033适合于容纳在第二个拼接件 20的凹槽 201的槽体中, 第一个 拼接件 20的凸块 203的颈部 2031适合于从第二个拼接件 20的凹槽 201的 开口伸出至槽体外部。 并且, 第一个拼接件 20的凸块 203可以沿着第二个 拼接件 20的凹槽 201的延伸方向滑动。 同时, 由于第一个拼接件 20的凸 块 203的头部 2033无法从第二个拼接件 20的凹槽 201的开口穿过, 因此, 当第一个拼接件 20的凸块 203与第二个拼接件 20的凹槽 201连接完毕后, 第一个拼接件 20的凸块 203只能沿着第二个拼接件 20的凹槽 201滑动, 而不会沿着第二个拼接件 20的凹槽 201的槽深的方向从凹槽 201中脱离。 第一个拼接件 20的凹槽 201与第二个拼接件 20的凸块 203的插接匹配方 式完全相同。  According to the above, when the two assembling pieces 20 are assembled, the head 2033 of the protrusion 203 of the first assembling piece 20 is adapted to be accommodated in the groove of the groove 201 of the second assembling piece 20, the first stitching The neck 2031 of the projection 203 of the member 20 is adapted to protrude from the opening of the recess 201 of the second splicing member 20 to the outside of the groove. Also, the bump 203 of the first splicing member 20 can slide along the extending direction of the groove 201 of the second splicing member 20. Meanwhile, since the head 2033 of the bump 203 of the first splicing member 20 cannot pass through the opening of the groove 201 of the second splicing member 20, the bump 203 and the second portion of the first splicing member 20 are After the grooves 201 of the splicing member 20 are connected, the protrusions 203 of the first splicing member 20 can only slide along the grooves 201 of the second splicing member 20 without being along the second splicing member 20. The direction of the groove depth of the groove 201 is detached from the groove 201. The groove 201 of the first splicing member 20 is exactly the same as the 203 of the second splicing member 20.
