Abstract
The utility model particularly discloses a speed-detecting device for a belt conveyor. The problem that the detected signal of the current speed-detecting device for the belt conveyor is not accurate when a belt deviates is solved. The speed-detecting device for the belt conveyor comprises a channel steel bracket of which the two ends are fixedly arranged on longitudinal beams on the two sides of the belt conveyor, wherein two lifting hooks are arranged on the middle part of the channel steel bracket and hang a speed sensor through a soft chain; the speed sensor is arranged on the surface of a rubber belt; and the length of the soft chain is more than the distance between the channel steel bracket and the rubber belt. The speed-detecting device is simple and reasonable in structure, and is firm and effective. The reliable and stable running of a combined mining road belt conveyor is ensured, so that the high yield and the high efficiency of coal mine production are ensured to certain degree.
Description
Technical field
The utility model relates to the speed detector that uses under the coal mine, is specially a kind of travelling apron speed measuring device.
Background technology
Employed speed detector is to utilize speed sensor to pass through detection to adhesive tape conveyor speed in the colliery, with the signal converting transmission to monitored control system, by the excessively coal quantitative analysis to transport systems, judge whether the adhesive tape of travelling apron the low speed sipping fault occurs.Speed sensor is to utilize iron wire to hang on the carriage of travelling apron, and friction drives the roller rotation of speed sensor during the belt walking, thereby produces speed signal.When sideslip appears in travelling apron; must adjust by adjusting bracket the sideslip of travelling apron; the drop point that so just causes speed sensor is not in the center of belt feeder; cause speed signal inaccurate; misoperation appears in the fender guard of equipment; had a strong impact on sensitieness and accuracy that system detects, and impact is produced.
Summary of the invention
The utility model provides a kind of travelling apron speed measuring device in order to solve the inaccurate problem of existing travelling apron speed measuring device detection signal when belt deviation skids.
The utility model is to adopt following technical scheme to realize: the travelling apron speed measuring device, comprise that two ends are fixed in the channel-section steel support on the longeron of travelling apron both sides, the channel-section steel mid-stent is provided with two suspension hooks, two suspension hooks are hung with a speed sensor that places on the tape surface by soft chain, and the length of soft chain is greater than the distance of channel-section steel support and adhesive tape.
During use, the mode of hanging can guarantee that speed sensor freely drops in the grooved angle of travelling apron, though adhesive tape slipping or sideslip, because the speed sensor location has flexibly accurately guaranteed the normal operation of speed sensor.
The beneficial effects of the utility model are as follows: utilize soft chain that speed sensor is hung on fixing channel-section steel support, guaranteed to install and use process medium velocity sensor and remained on the belt feeder center.The utility model is simple and reasonable, firmly effectively, effectively guarantees to combine to adopt the reliable and stable operation of gateway belt machine, thereby has ensured to a certain extent the high-yield and high-efficiency of coal production.
Description of drawings
Fig. 1 is structural representation of the present utility model.
