Description
技术领域technical field
本发明是针对于重载结构的一种新型安装方式，具有较强的抗扭能力和稳定性，适用于重载机构的通用化安装接口。The invention is a novel installation method for heavy-duty structures, has strong torsion resistance and stability, and is suitable for generalized installation interfaces of heavy-duty structures.
背景技术Background technique
重载机构在工程机械领域中广泛存在。特别是在行走机械中，工作机构一般需要克服很大的负载力，本身结构比较庞大，各个连接模块的质量比较大，是典型的重载机构。重载机构中关键模块，一般具有容易出现故障的特点，需要定期或者出现故障的情况下及时更换，常通过固定连接的形式以其他模块结构连接。由于需要克服很大的工作阻力，这些重载机构各模块之间的固定连接安装结构不仅需要提供很大的径向和轴向的拉压力，而且还需要承受很大的扭矩，这直接关系到连接部分的稳定性和整个机构在工作过程的质量和效率。为了增强结构的通用性来提高工作效率，在不同工况下，同一连接部位需要尽可能适应多种重载机构的安装与连接，即需要一种高效、通用化的连接形式。怎样可以承受最大的扭矩，怎样提高连接的稳定性和可靠性，怎样尽可能适用最多机构的安装与更换，是重载机构的连接形式追求的目标。Heavy-duty mechanisms widely exist in the field of construction machinery. Especially in mobile machinery, the working mechanism generally needs to overcome a large load force, the structure itself is relatively large, and the mass of each connecting module is relatively large, which is a typical heavy-duty mechanism. The key modules in the heavy-duty mechanism are generally prone to failure. They need to be replaced regularly or in time when a failure occurs. They are often connected with other module structures in the form of fixed connections. Due to the need to overcome a large working resistance, the fixed connection and installation structure between the modules of these heavy-duty mechanisms not only needs to provide a large radial and axial tension, but also needs to bear a large torque, which is directly related to The stability of the connected parts and the quality and efficiency of the entire mechanism in the working process. In order to enhance the versatility of the structure and improve work efficiency, under different working conditions, the same connection part needs to adapt to the installation and connection of various heavy-duty mechanisms as much as possible, that is, an efficient and universal connection form is required. How to withstand the maximum torque, how to improve the stability and reliability of the connection, and how to apply the installation and replacement of as many mechanisms as possible are the goals pursued by the connection form of the heavy-duty mechanism.
传统的连接方式，一般是前端面或者侧面法兰连接，这种形式结构比较简单，但是其承受的扭矩会转化到螺栓上的拉力或者剪切力，这种结构抗扭能力较弱，而且连接接口不易扩展；采用方形盘接口来抵抗扭矩的连接形式，能够将扭矩传递到方形结构上，而不是螺栓上，这样就会大大增加了其抗扭的特性，并且这种结构结合侧面法兰结构，有效抵抗侧向拉力，具有很好的稳定性。目前，方形连接在多边形传动轴有应用，主要来提供比较大的扭矩，但是方形盘结合侧面法兰的连接形式并没有作为大型重载机构连接形式出现。并且传统的端面连接方式只是针对特定的连接结构，而方形盘连接形式具有很强的通用性，可以在多种机构中相互通用，可以大大降低机械的故障损失。设计一种抗扭矩性和稳定性都很强的通用化的连接形式，是提高机构工作效率和质量的一种有效手段，而且是很有必要的。The traditional connection method is generally the front face or the side flange connection. The structure of this form is relatively simple, but the torque it bears will be converted into the tension or shear force on the bolt. This structure has weak torsion resistance, and the connection The interface is not easy to expand; the connection form of the square plate interface to resist the torque can transmit the torque to the square structure instead of the bolt, which will greatly increase its torsion resistance characteristics, and this structure combined with the side flange structure , effective resistance to lateral pull, with good stability. At present, the square connection is applied to the polygonal transmission shaft, mainly to provide a relatively large torque, but the connection form of the square disc combined with the side flange has not appeared as a connection form of a large-scale heavy-duty mechanism. Moreover, the traditional end-face connection method is only for a specific connection structure, while the square disc connection form has strong versatility and can be used in various mechanisms, which can greatly reduce mechanical failure losses. Designing a universal connection form with strong torque resistance and stability is an effective means to improve the working efficiency and quality of the mechanism, and it is very necessary.

具体实施方式detailed description
参照附图1-5：Referring to attached drawings 1-5:
一种重载机构的高抗扭连接结构，设置在被相互连接的第一机构与第二机构之间，其特征在于：固第一机构的侧面通过方盘连接结构连接第二机构；所述的方盘连接结构包括固结在所述的第一机构的侧面的方形安装盘和设置在所述的方形安装盘周围的侧面法兰，所述的第二机构设置有方形槽，所述的方形安装盘的顶部有便于将所述的方形安装盘纳入所述的方形槽的锲型倒角；所述的侧面法兰通过螺钉连接所述的第二机构；A high torsion-resistant connection structure of a heavy-duty mechanism, which is arranged between a first mechanism and a second mechanism that are connected to each other, is characterized in that: the side of the first mechanism is connected to the second mechanism through a square plate connection structure; The square plate connection structure includes a square mounting plate fixed on the side of the first mechanism and a side flange arranged around the square mounting plate, the second mechanism is provided with a square groove, and the The top of the square mounting plate has a wedge-shaped chamfer that facilitates putting the square mounting plate into the square groove; the side flange is connected to the second mechanism by screws;
所述的第一机构的后端配置可以安装驱动模块的端面法兰；所述的第一机构有供传动轴或管路通过的内腔和通孔。The rear end of the first mechanism can be equipped with the end face flange of the drive module; the first mechanism has an inner cavity and a through hole for the transmission shaft or pipeline to pass through.
下面以这种新型安装结构在滚筒式露天采煤机的工作机构上的应用为例，结合附图对本发明作进一步描述。Taking the application of this new installation structure on the working mechanism of the drum type surface coal mining machine as an example below, the present invention will be further described in conjunction with the accompanying drawings.
这种新型安装结构通过方形安装盘3安装在采煤机小臂上的方形安装槽10上面，然后在通过侧面法兰2用螺栓对整个结构进行紧密固定，达到高抗扭和高稳定性两项目的。这种安装结构是中空结构，前后留有通孔，后侧设计成通用的端面法兰1，可以安装液压安装块7，也可以安装电机安装块9，液压管路6和电机传动轴8都可以通过新型结构的前后通孔5将动力传到采煤机的滚筒进行截煤工作。This new installation structure is installed on the square installation groove 10 on the small arm of the shearer through the square installation plate 3, and then the whole structure is tightly fixed with bolts through the side flange 2 to achieve both high torsion resistance and high stability. The project. This installation structure is a hollow structure, with through holes left and right, and the rear side is designed as a universal end face flange 1, which can be installed with a hydraulic installation block 7 or a motor installation block 9. The hydraulic pipeline 6 and the motor drive shaft 8 are both Power can be transmitted to the drum of the shearer through the front and rear through holes 5 of the novel structure for coal cutting work.
方形安装盘3与安装槽10的安装是方形方式安装，这样所承受的扭矩全部会转化到方形安装盘上，这样使得抗扭能力比单纯的螺栓抗扭要大很多。方形安装要想实现比较好的切向稳定性，就必须要求方形结构具有相对高的加工精度，而加工精度高就会增加安装装配的难度。为此，在方形安装结构的端面做锲角，安装时通过锲型结构4的导向作用，方便地将方形安装盘3装入方形安装槽10。由于采用的是侧面安装形式，这种结构也存在轴向的稳定性问题，为此，我们在方形安装盘旁边设计了侧面法兰2与小臂连接，这样就会使得整个结构具有很强的稳定性。后置端面法兰1比较通用，适应不同驱动形式的安装模块(主要是液压驱动和电机驱动两大形式)，安装和拆卸都比较方便。方形安装盘3和后置的端面法兰1，都比较通用化，可以作为一种通用的重载机构安装结构，同时具有高抗扭性和高稳定性。The installation of the square mounting plate 3 and the mounting groove 10 is installed in a square manner, so that all the borne torque will be converted to the square mounting plate, so that the torsional resistance is much larger than that of simple bolts. In order to achieve better tangential stability for square installation, the square structure must have relatively high machining accuracy, and high machining accuracy will increase the difficulty of installation and assembly. For this reason, a corner is made on the end face of the square mounting structure, and the square mounting plate 3 is conveniently loaded into the square mounting groove 10 through the guiding effect of the wedge-shaped structure 4 during installation. Due to the side installation, this structure also has axial stability problems. For this reason, we designed a side flange 2 next to the square mounting plate to connect with the arm, which will make the whole structure have a strong stability. The rear end face flange 1 is more general, suitable for installation modules of different drive forms (mainly two forms of hydraulic drive and motor drive), and it is relatively convenient to install and disassemble. Both the square mounting plate 3 and the rear end flange 1 are more generalized, and can be used as a general mounting structure for heavy-duty mechanisms, while having high torsion resistance and high stability.
