Description
技术领域technical field
本发明涉及振动筛，尤其涉及一种可实现变刚度功能和弹簧更换简单等特点的振动筛橡胶弹簧安装结构以及橡胶弹簧更换方法。The invention relates to a vibrating screen, in particular to a rubber spring installation structure of a vibrating screen and a rubber spring replacement method capable of realizing variable stiffness functions and simple spring replacement.
背景技术Background technique
振动筛是在采矿业、石油开采业、农业、建筑业等多种行业领域广泛应用的一种机械设备，可实现筛分、脱水、脱介等功能。振动筛的筛箱和安装底座之间通过减振弹簧连接，常用的减振弹簧有金属弹簧、橡胶弹簧、复合弹簧等。由于橡胶弹簧成本低廉，具有良好的减振效果、以及良好的耐寒性、气密性、防水性、电绝缘性等优点，橡胶弹簧成为振动筛设备中减振弹簧的首要选择。然而，在振动筛的运行过程中，由于橡胶弹簧和安装导杆之间不断地摩擦，会产生大量的热。同时，由于在制造及安装过程中存在误差，造成橡胶弹簧在承受上下方向的摩擦力同时还会承受安装导杆对其产生的侧向剪切力，这些都是造成橡胶弹簧易破坏的因素。目前大量使用的振动筛橡胶弹簧安装结构，橡胶弹簧一般安装在筛箱正下方，通过安装导杆与下支撑板交接，在更换橡胶弹簧时将需要动用千斤顶等设备，给设备维修带来了非常大的麻烦。为克服弹簧更换的困难，有技术人员对振动筛橡胶弹簧的安装结构做了改进，将橡胶弹簧安装在筛箱侧面，下支撑板与筛箱采用螺栓连接，但在这种改进的技术中存在着严重的问题，如在振动筛的运行过程中，存在较严重的撞击，产生大量噪声，且橡胶弹簧只能实现压缩而不能实现拉伸，新弹簧在更换的过程中由于不能自动产生变形而不能顺利的放入筛箱之间，因此这种发明的实用性存在问题。基于以上问题，设计了振动筛橡胶弹簧安装结构。Vibrating screen is a kind of mechanical equipment widely used in various industries such as mining, oil extraction, agriculture, construction, etc. It can realize functions such as screening, dehydration, and de-intermediation. The screen box of the vibrating screen and the installation base are connected by a damping spring. Commonly used damping springs include metal springs, rubber springs, and composite springs. Due to the low cost of rubber springs, good vibration damping effect, and good cold resistance, air tightness, waterproof, electrical insulation and other advantages, rubber springs have become the first choice for vibration damping springs in vibrating screen equipment. However, during the operation of the vibrating screen, a lot of heat will be generated due to the constant friction between the rubber spring and the installation guide rod. At the same time, due to errors in the manufacturing and installation process, the rubber spring bears the friction force in the up and down direction and also bears the lateral shear force generated by the installation guide rod. These are the factors that cause the rubber spring to be easily damaged. At present, the rubber spring installation structure of the vibrating screen is widely used. The rubber spring is generally installed directly under the screen box. Through the installation of the guide rod and the connection with the lower support plate, it will be necessary to use jacks and other equipment when replacing the rubber spring, which brings great inconvenience to equipment maintenance. Big trouble. In order to overcome the difficulty of spring replacement, some technicians have improved the installation structure of the rubber spring of the vibrating screen. The rubber spring is installed on the side of the screen box, and the lower support plate and the screen box are connected by bolts. However, in this improved technology, there are There are serious problems, such as during the operation of the vibrating screen, there are serious impacts, which generate a lot of noise, and the rubber spring can only be compressed but not stretched. The new spring cannot automatically deform during the replacement process. It does not fit smoothly between the screen boxes, so the practicality of this invention is questionable. Based on the above problems, the rubber spring installation structure of the vibrating screen is designed.
