Abstract
The utility model relates to a speed detector for a coal belt conveyer, comprising a speed detection rack, a speed detection roller, a speed detection wheel, a positioning rack and a sensor. The speed detection roller is mounted on the speed detection rack and closely clings to an upper side surface of a lower layer belt to rotate along with the belt. The speed detection wheel is coaxial with the speed detection roller in rigid connection and the sensor is mounted on the radial direction of the speed detection wheel and a pulse signal output end of the sensor is connected with a single-chip microcomputer signal input end in a monitoring main machine of the belt conveyer. The device can reliably operate for a long time under harsh environment below the coal mine, therefore the production efficiency is increased.
Description
Technical field
The utility model belongs to colliery electromechanical equipment technical field, is specifically related to a kind of speed measuring device that is used for coal conveyor belt.
Background technology
The measurement of coal conveyor belt belt linear velocity is the requisite link of Safety of Coal Mine Production, because environmental baseline is abominable under the coal mine, existing many speed measuring devices can not move reliably and with long-term, thereby have influenced production.
The utility model content
The purpose of this utility model provides a kind of speed measuring device that is used for coal conveyor belt, can be at the medium-term and long-term reliability service of rugged environment; This device and belt conveyer supervisory system are used, and have effectively ensured the safe operation of belt conveyer, thereby have improved production efficiency.
Technical solution of the present utility model is as follows:
A kind of speed measuring device that is used for coal conveyor belt comprises the frame that tests the speed, the cylinder that tests the speed, fifth wheel, locating rack, sensor;
The frame that tests the speed is fixed on the position of close changed course cylinder above the descending belt of belt conveyer, the cylinder that tests the speed is installed on the frame that tests the speed, the cylinder that tests the speed is close to the upper side of lower floor's belt, rotate with belt, the fifth wheel and the cylinder that tests the speed are total to central shaft and are rigidly connected, fifth wheel is a dentalation, sensor is installed in the radial direction of fifth wheel, and be fixed on the locating rack, sensor magnetic induction end face and fifth wheel external cylindrical surface are approaching, and a signal input part of the single-chip microcomputer in the pulse signal output end of sensor and the belt conveyer monitoring host computer is connected.
Sensor adopts magnetic inductive near switch sensor.
Good effect of the present utility model is: this device has been owing to adopted magnetic induction sensor, thereby can be at the medium-term and long-term reliably working of rugged surroundings, thereby reduced the fault of band conveyor operation, improved as economic benefit.
Description of drawings
Fig. 1 is the utility model scheme of installation.
Fig. 2 is the utility model sensor construction synoptic diagram.
Embodiment
As Fig. 1, shown in Figure 2: a kind of speed measuring device that is used for coal conveyor belt comprises the frame that tests the speed, the cylinder that tests the speed, fifth wheel 1, locating rack 2, sensor 4; The frame that tests the speed is fixed on the position of close changed course cylinder above the descending belt of belt conveyer, the cylinder that tests the speed is installed on the frame that tests the speed, the cylinder that tests the speed is close to the upper side of lower floor's belt, rotate with belt, the fifth wheel 1 and the cylinder that tests the speed are total to central shaft and are rigidly connected, fifth wheel 1 is a dentalation, sensor 4 is installed on the locating rack 2 by hold-down nut 3, and be positioned at the radial direction of fifth wheel 1, and be fixed on the locating rack 2, sensor 4 magnetic induction end faces and fifth wheel 1 external cylindrical surface are approaching, and a signal input part of the single-chip microcomputer in the pulse signal output end of sensor 4 and the belt conveyer monitoring host computer is connected.
The frame cylinder that tests the speed of sensor is close to the upper side of lower floor's belt feeder, follows belt and rotates.Speed detection sensor detects magnetic induction pulses information and passes to main frame and count processing, through calculation process, calculate current linear velocity value and demonstration, inner single-chip microcomputer compares actual measured value with setting linear velocity value Ve simultaneously, if measuring speed is less than setting value, and continuous time, scope was greater than setting-up time, and main frame is the outputting parking signal immediately.
Claims (2)
1. speed measuring device that is used for coal conveyor belt is characterized in that: comprise the frame that tests the speed, the cylinder that tests the speed, fifth wheel, locating rack, sensor;
The said frame that tests the speed is fixed on the position of close changed course cylinder above the descending belt of belt conveyer, the cylinder that tests the speed is installed on the frame that tests the speed, the cylinder that tests the speed is close to the upper side of lower floor's belt, rotate with belt, the fifth wheel and the cylinder that tests the speed are total to central shaft and are rigidly connected, fifth wheel is a dentalation, sensor is installed in the radial direction of fifth wheel, and be fixed on the locating rack, sensor magnetic induction end face and fifth wheel external cylindrical surface are approaching, and a signal input part of the single-chip microcomputer in the pulse signal output end of sensor and the belt conveyer monitoring host computer is connected.
2. a kind of speed measuring device that is used for coal conveyor belt according to claim 1 is characterized in that: described sensor adopts magnetic inductive near switch sensor.
