Description

一种塔式起重机起重臂臂节间的穿销油缸支架结构A support structure of pin-through cylinders between the boom sections of a tower crane

技术领域technical field

本发明涉及一种起重臂臂节间的连接方式,具体是一种塔式起重机起重臂臂节间的穿销油缸支架结构,属于塔式起重机起重臂臂节连接技术领域。The invention relates to a connection mode between jib sections of a boom, in particular to a pin-through oil cylinder support structure between jib sections of a tower crane, and belongs to the technical field of jib section connection of tower cranes.

背景技术Background technique

塔式起重机起重臂作为承受吊载的桁架结构,由主弦和腹杆组成,其起重臂相邻臂节之间大都采用拼接的方式安装,并利用销轴连接。如图1所示,起重臂臂节之间连接时,可将一个臂节的内耳板4插入另一臂节的外耳板3内,调整两个臂节的位置,待内外耳板上的销轴孔对准时,将销轴1打入销轴孔内,并插入防止销轴径向移动的锁销2。该结构在安装时,销轴的打进打出需要人力用锤来完成,操作不便,安装困难,而且安装过程中的安全性较低,人工用力易损坏销轴及结构件,影响发货使用。如果在发货前将销轴安装好,则会增加生产加工成本和运输成本,影响发货效率。As a truss structure to bear the load, the jib of the tower crane is composed of the main chord and the web. Most of the adjacent jib sections of the jib are installed by splicing and connected by pins. As shown in Figure 1, when the jib sections are connected, the inner ear plate 4 of one jib section can be inserted into the outer ear plate 3 of the other jib section, and the positions of the two jib sections can be adjusted. When the pin shaft holes are aligned, drive the pin shaft 1 into the pin shaft hole, and insert the lock pin 2 to prevent the pin shaft from moving radially. When the structure is installed, the driving in and out of the pin shaft needs manpower to complete with a hammer, which is inconvenient to operate, difficult to install, and the safety in the installation process is low, and the pin shaft and structural parts are easily damaged by manual force, which affects delivery and use. If the pin shaft is installed before shipment, it will increase production and processing costs and transportation costs, affecting delivery efficiency.

目前,业内对改善上述现象所采取的方案是:如图1所示,在臂节外耳板销轴孔的周围焊接一个导向弯板6,安装时将销轴顺着导向弯板插入相邻臂节内外耳板的销轴孔内,用大锤等工具再把销轴砸穿出外耳板,插上导向弯板上的锁销,防止销轴径向移动;拆卸时,用大锤等工具将销轴砸出销轴孔,对留在导向弯板中的销轴插上锁销,固定销轴在导向弯板内,随机发货即可。这种方案虽然无需在发货前将臂节连接好,但仍需采用大锤完成销轴的打进打出,安装拆卸困难,易损坏销轴及结构件,影响发货使用。At present, the solution adopted by the industry to improve the above phenomenon is: as shown in Figure 1, a guide bending plate 6 is welded around the pin shaft hole of the outer ear plate of the arm section, and the pin shaft is inserted into the adjacent arm along the guide bending plate during installation. In the pin shaft hole of the inner and outer ear plates of the joint, use tools such as a sledgehammer to smash the pin shaft out of the outer ear plate, and insert the lock pin on the guide bending plate to prevent the pin shaft from moving radially; when disassembling, use tools such as a sledgehammer Smash the pin shaft out of the pin shaft hole, insert the lock pin on the pin shaft left in the guide bending plate, fix the pin shaft in the guide bending plate, and ship it randomly. Although this solution does not need to connect the boom sections before delivery, it still needs to use a sledgehammer to complete the driving in and out of the pin shaft. It is difficult to install and disassemble, and it is easy to damage the pin shaft and structural parts, which will affect the delivery and use.
