Description
技术领域technical field
本实用新型涉及一种对运输皮带速度进行精确检测的电子装置，尤其能适合运输皮带表面含水量大、主动轴偏心严重的皮带速度测量。The utility model relates to an electronic device for accurately detecting the speed of a conveying belt, which is especially suitable for measuring the speed of the conveying belt with high water content on the surface and severe eccentricity of the driving shaft.
背景技术Background technique
目前，工业过程对于运输皮带速度的检测主要采用阻尼轮式测速装置和连轴式测速装置。阻尼轮式测速装置的阻尼轮靠重力紧贴在下部皮带的表面，皮带运动时产生转动，由此测量皮带的速度，其测量的最大问题是：当皮带表面含水量大或由于阻尼轮接触皮带部分变得光滑而使阻尼轮打滑时，将无法测量皮带的速度。连轴式测速装置克服了阻尼轮式测速装置存在的不足，将测速装置连接安装在运输皮带主动轮的轴承的外端轴，并且与转轴同心，测速装置随轴的转动而转动，但由于对安装要求高，在一些存在较大轴偏心的场合，容易将测速装置挣脱而无法进行测量，另外当运输皮带主动轮进行检修时，需要将装置拆下，再安装需要精确校准，很不方便。At present, the industrial process mainly adopts the damping wheel type speed measuring device and the coupling speed measuring device for the detection of the speed of the conveying belt. The damping wheel of the damping wheel type speed measuring device is close to the surface of the lower belt by gravity, and the belt rotates when it moves, thereby measuring the speed of the belt. The speed of the belt will not be measured when the damper wheel slips due to slippery sections. The shaft-connected speed measuring device overcomes the shortcomings of the damping wheel speed measuring device. The speed measuring device is connected to the outer end shaft of the bearing of the driving wheel of the conveyor belt, and is concentric with the rotating shaft. The speed measuring device rotates with the rotation of the shaft, but due to the The installation requirements are high. In some occasions where there is a large shaft eccentricity, the speed measuring device is easy to break free and cannot be measured. In addition, when the driving pulley of the transport belt is overhauled, the device needs to be removed, and the installation needs precise calibration, which is very inconvenient.
发明内容Contents of the invention
为了克服现有运输皮带速度测量装置存在的不足，提供一种新型的皮带速度测量装置，该测速装置能克服以上两种测速装置存在的不足，能精确地对皮带速度进行测量，安装、调试十分方便。In order to overcome the shortcomings of the existing conveyor belt speed measuring device, a new type of belt speed measuring device is provided. This speed measuring device can overcome the shortcomings of the above two speed measuring devices, and can accurately measure the belt speed. It is very easy to install and debug. convenient.
本实用新型的技术方案为：速度测量装置由测速齿轮和接近开关组成，测速齿轮分为上、下两部分，夹装在皮带机主动轮的轴承与辊筒之间的轴上，并通过两颗螺栓紧固；即在运输皮带的轴承与辊筒之间的轴上夹装一个测速齿轮，齿轮有八颗齿，均匀分布在同一圆周上，在测速齿轮的正上方安装一霍尔式接近开关，接近开关的探测端与测速齿轮的齿面距离为3～10mm。The technical scheme of the utility model is: the speed measuring device is composed of a speed measuring gear and a proximity switch. Fasten the bolts; that is, a speed measuring gear is clamped on the shaft between the bearing of the conveyor belt and the roller. The gear has eight teeth, which are evenly distributed on the same circumference. A Hall-type approach is installed directly above the speed measuring gear. Switch, the distance between the detection end of the proximity switch and the tooth surface of the speed measuring gear is 3-10mm.
采用接近开关作为信号产生元件，接近开关安装在齿轮的上方或侧面适当位置，当测速齿轮转动时，由于齿面经过接近开关而产生电脉冲。The proximity switch is used as the signal generating element, and the proximity switch is installed at an appropriate position above or on the side of the gear. When the speed measuring gear rotates, an electric pulse is generated due to the tooth surface passing the proximity switch.
当皮带主动轮转动时，测速齿轮也随之转动，当一个齿面经过接近开关时，相应产生一个脉冲，可将脉冲信号传送给PLC、计算机、控制器等设备。通过测量单位时间内的脉冲数，并结合辊筒的直径，即可计算出运输皮带的速度。由于测速齿轮是通过螺丝夹装在轴承上的，拆卸和安装都非常方便，另外，接近开关的安装位置允许在一定范围变化，因此不受转轴偏心或安装位置精确度的影响。When the belt driving wheel rotates, the speed measuring gear also rotates accordingly. When a tooth surface passes the proximity switch, a corresponding pulse is generated, which can transmit the pulse signal to PLC, computer, controller and other equipment. By measuring the number of pulses per unit time, combined with the diameter of the roller, the speed of the conveyor belt can be calculated. Since the speed measuring gear is clamped on the bearing by screws, it is very convenient to disassemble and install. In addition, the installation position of the proximity switch is allowed to change within a certain range, so it is not affected by the eccentricity of the rotating shaft or the accuracy of the installation position.
