Abstract
The utility model discloses a drive sprocket operating condition detection device, and pertains to a sprocket operating detection device provided with a fixed sprocket apparatus. The drive sprocket operating condition detection device comprises a sprocket (3) and a rotary encoder (4) which is installed on the spindle nose of the sprocket (3). A detection head (1) is installed at the sprocket hole of the sprocket (3). The detection head (1) is connected with a controller (2). The controller (2) is connected with the rotary encoder (4). The drive sprocket operating condition detection device of the utility mode is used to perform detection on the sprocket, so the condition that a lock sleeve for fixing the sprocket looses or the condition that a pin between the sprocket and the spindle is broken can be found out timely, and a signal is given out to stop the operation of a machine and notify workers to check the state of the lock sleeve and the pin and perform maintenance, so that the occurrence of production accidents can be avoided.
Description
Technical field
The utility model belongs to the sprocket wheel of fixed chain wheels equipment operation pick-up unit, especially a kind of pick-up unit of drive sprocket operating condition.
Background technology
Adopt at present rotary encoder to be installed on the motion state that sprocket wheel spindle nose detects sprocket wheel, loosening when the lock sleeve of fixed chain wheels, or the fracture of the pin between sprocket wheel and axle, will produce spindle nose and sprocket wheel and can not synchronize rotation phenomenon.When this phenomenon produces, the rectangular pulse signal frequency spectrum that rotary encoder provides, electrical control equipment cannot be judged the motion state of sprocket wheel, thereby causes industrial accident.
Summary of the invention
The purpose of this utility model is to design a kind of pick-up unit of drive sprocket operating condition, can be loosening at the lock sleeve of fixed chain wheels, or the pin between sprocket wheel and axle when fracture, detects spindle nose and sprocket wheel and can not synchronize rotation phenomenon, thereby avoid the generation of industrial accident.
The utility model is achieved like this: a kind of pick-up unit of drive sprocket operating condition, comprise sprocket wheel (3) and be arranged on the rotary encoder (4) of sprocket wheel (3) spindle nose, perforation place installation and measuring head (1) at sprocket wheel (3), detection head (1) is connected with controller (2), and the square wave that while rotating by detecting sprocket wheel (3), perforation produces detection head (1) sends controller (2) to; Controller (2) is connected with rotary encoder (4), calculates the rotating speed of sprocket wheel (3) by square wave, and compares with the chain wheel speed that rotary encoder (4) is measured, and when two rotating speeds are consistent, belongs to fixed chain wheels working properly; When two rotating speeds are inconsistent, may occur that the lock sleeve of fixed chain wheels is loosening, or the situation of the fracture of the pin between sprocket wheel and axle, controller (2) sends signal and stops machine run, notify staff to check the state of lock sleeve and pin, safeguard, avoid the generation of industrial accident.
Described detection head (1) and controller (2) can be made the task that a detecting unit completes pick-up unit.
With the pick-up unit of drive sprocket operating condition described in the utility model, sprocket wheel is detected, the lock sleeve that can find in time fixed chain wheels is loosening, or the situation of the fracture of the pin between sprocket wheel and axle, and send signal and stop machine run, notify staff to check the state of lock sleeve and pin, safeguard, avoid the generation of industrial accident.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and scheme of installation.
In figure: 1-detection head, 2-controller, 3-sprocket wheel, 4-rotary encoder.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing 1, the utility model is described in further detail.
Detection head (1) is arranged on the perforation place of sprocket wheel (3), when sprocket wheel (3) rotates, detection head (1) has by detection that tooth is anodontia to be produced square wave and send controller (2) to, controller (2) calculates the rotating speed of sprocket wheel by square wave, and compare with sprocket wheel (3) rotating speed that rotary encoder (4) is measured, when two rotating speeds are consistent, belong to fixed chain wheels working properly; When two rotating speeds are inconsistent, may occur that the lock sleeve of fixed chain wheels is loosening, or the situation of the fracture of the pin between sprocket wheel and axle, controller (2) sends signal and stops machine run, notify staff to check the state of lock sleeve and pin, safeguard, avoid the generation of industrial accident.Detection head (1) and controller (2) can be made to the task that a detecting unit completes pick-up unit.
Claims (2)
1. the pick-up unit of a drive sprocket operating condition, comprise sprocket wheel (3) and be arranged on the rotary encoder (4) of sprocket wheel (3) spindle nose, it is characterized in that, perforation place installation and measuring head (1) at sprocket wheel (3), described detection head (1) is connected with controller (2), and controller (2) is connected with rotary encoder (4).
2. the pick-up unit of drive sprocket operating condition as claimed in claim 1, is characterized in that, described detection head (1) and controller (2) are made a detecting unit.
