Description
技术领域 technical field
本实用新型涉及一种升降设备，具体属于一种垂直升降机构用链条传动机构。 The utility model relates to a lifting device, in particular to a chain transmission mechanism for a vertical lifting mechanism.
背景技术 Background technique
升降机在社会中的应用非常普片，例如：消防升降平台、路灯维修车、酒店、工矿等等。这些升降机采用的都是气压、液压折叠或曲臂升降系统以及链条导轨升降系统。这些升降机都是在大型场所使用如停车场、酒店、工矿等。无法适用到流水生产线上。流水生产线使用的输送设备都采用单一的丝杆驱动剪叉式升降方式。这种结构为了保证升降的灵活性大都采用了大间隙的设计，在升降过程中非常不稳定，导致输送平台在上升或下降的过程中前后或左右摇摆。并且为了自动化的需求在多种高度的调节上采用大量的传感器来实现不同高度的自动反馈。在结构上和控制上都增加了复杂程度。 The application of elevators in society is very common, such as: fire-fighting lifting platforms, street lamp maintenance vehicles, hotels, industrial and mining, etc. These lifts are all pneumatic, hydraulic folding or crank arm lifting systems and chain guide rail lifting systems. These lifts are used in large places such as parking lots, hotels, industrial and mining, etc. It cannot be applied to the assembly line. The conveying equipment used in the assembly line adopts a single screw driven scissor lifting method. In order to ensure the flexibility of lifting, this structure mostly adopts the design of large gap, which is very unstable during the lifting process, causing the conveying platform to swing back and forth or left and right during the process of rising or falling. And in order to meet the needs of automation, a large number of sensors are used in the adjustment of various heights to achieve automatic feedback of different heights. Increased complexity both structurally and in control.
为了解决上述问题我公司在开发自动灌装线中升降输送机时，研发了单驱动四点垂直升降机构。 In order to solve the above problems, our company developed a single-drive four-point vertical lifting mechanism when developing the lifting conveyor in the automatic filling line.
实用新型内容 Utility model content
本实用新型的目的是提供一种垂直升降机构用链条传动机构，属于自动生产线升降输送的设备，自动化程度高，运行平稳。 The purpose of the utility model is to provide a chain transmission mechanism for a vertical lifting mechanism, which belongs to the equipment for lifting and conveying in an automatic production line, with high degree of automation and stable operation.
本实用新型的技术方案如下： The technical scheme of the utility model is as follows:
一种垂直升降机构用链条传动机构，包括有安装座，安装座四个拐角处安装有从动滚子链轮，四个从动滚子链轮啮合有闭合的从动滚子链条，从动滚子链条外侧配合有两个惰轮、两个张紧链轮，其中一个从动滚子链轮通过主动滚子链条传动连接有主动滚子链轮，主动滚子链轮外连接有伺服电机。 A chain transmission mechanism for a vertical lifting mechanism, including a mounting seat, driven roller sprockets are installed at the four corners of the mounting seat, and the four driven roller sprockets are engaged with a closed driven roller chain. There are two idlers and two tensioning sprockets on the outer side of the roller chain, one of which is connected to the driving roller sprocket through the driving roller chain transmission, and the driving roller sprocket is connected to the servo motor .
所述的从动滚子链条外侧配合有链条导轨。 The outer side of the driven roller chain is equipped with a chain guide rail.
本实用新型控制部分包括上位机及可编程逻辑控制器PLC（或人机对话触摸屏进行脉冲控制）等电控部分和气动部分。机械部分就是给传动结构提供支撑的其它部分。本实用新型属于自动生产线升降输送的设备，自动化程度高，运行平稳。 The control part of the utility model includes an electric control part such as a host computer and a programmable logic controller PLC (or a man-machine dialogue touch screen for pulse control) and a pneumatic part. The mechanical part is the other part that provides support for the transmission structure. The utility model belongs to equipment for lifting and conveying in an automatic production line, which has a high degree of automation and stable operation.
本实用新型的工作原理： Working principle of the utility model:
当伺服电机转动时带动主动链轮转动，主动链轮中链轮带动主动滚子链条，主动滚子链条带动从动滚子链轮，从动滚子链轮带动从动滚子链条一起转动，从动滚子链条带动其他三个从动滚子链轮转动。一个主动链轮和三个从动滚子链轮分别与四个滚珠丝杠丝杆连接，并带动滚珠丝杠转动，滚珠丝杠组件中的滚珠丝杠螺母被固定在底座的立柱上，而滚珠丝杠组件中的滚珠丝杠丝杆通过从动滚子链轮与安装座连接，因此滚珠丝杠组件转动时，将安装座上下升降。 When the servo motor rotates, it drives the driving sprocket to rotate, the sprocket in the driving sprocket drives the driving roller chain, the driving roller chain drives the driven roller sprocket, and the driven roller sprocket drives the driven roller chain to rotate together. The driven roller chain drives the other three driven roller sprockets to rotate. One driving sprocket and three driven roller sprockets are respectively connected with four ball screw screws, and drive the ball screw to rotate. The ball screw nut in the ball screw assembly is fixed on the column of the base, and The ball screw screw in the ball screw assembly is connected to the mounting base through the driven roller sprocket, so when the ball screw assembly rotates, the mounting base is raised and lowered.
为了保护滚珠丝杠组件，增加了防尘罩，防尘罩的两端利用不锈钢扎带分别与固定在安装座上的端盖和滚珠丝杠组件中的滚珠丝杠螺母连接。 In order to protect the ball screw assembly, a dust cover is added, and the two ends of the dust cover are respectively connected with the end cover fixed on the mounting base and the ball screw nut in the ball screw assembly by stainless steel cable ties.
为了保证过长的从动滚子链条传动灵活和张紧力，分别在安装座的合适位置分别设置了链条导轨、以及两个张紧链轮组件和两个惰轮。 In order to ensure the flexible transmission and tension of the overlong driven roller chain, chain guide rails, two tensioning sprocket assemblies and two idler wheels are respectively arranged at appropriate positions of the mounting base.
防止滚珠丝杠组件中的滚珠丝杠丝杆在上升过程中旋出丝杠螺母在底座上设置了限位传感器。 To prevent the ball screw screw in the ball screw assembly from unscrewing the screw nut during the ascent process, a limit sensor is set on the base.
