Abstract
The utility model relates to a speed sensing device, in particular to a speed sensor of a belt conveyor, which aims at solving the problem of setting excessive magnetic bodies for the existing speed sensor of the belt conveyor, and comprises the magnetic bodies and a signal receiver matched with the magnetic bodies, wherein two magnetic bodies which take the center of a turunabout drum as a symmetric point are mounted on a side plate of the turunabout drum, and a probe of the signal receiver is mounted on a support on the outer side of the side plate of the turunabout drum. The magnetic bodies continuously send pulses to the probe of the signal receiver along with the rotation of the turunabout drum, and the probe of the signal receiver transmit received signals to a controller of the belt conveyor for processing and calculating the rotational speed. The speed sensor of the belt conveyor has the advantages of simple structure, low manufacturing cost and convenient maintenance.
Description
Technical field
The utility model relates to a kind of speed sensing device, is specially the speed pickup that a kind of belt conveyor is used.
Background technology
The band conveyor operation time need be monitored its belt speed, judges whether belt exists the speed of owing, skids and the situation and the warning in time of broken belt.The band conveyor speed pickup that uses has contact speed pickup and contactless speed pickup at present, the contact speed pickup is to be contacted with belt by roller, be contained in the rotational pulse sensor on the roller, send out a series of pulse, certain distance value is being represented in each pulse, thereby can measure linear velocity.The contactless speed pickup that uses is that magnetic is installed on the belt at present, the pulse signal sensing head is installed on the fixed sensing support, when belt moves, signal source is through the pulse signal sensing head, and maintain a certain distance with sensing head, after the magnetic that moves with belt is respectively through two sensing probes, can draw the linear velocity of belt operation through time of two sensing probes by the distance between two sensing probes and magnetic.The roller of contact speed pickup and belt friction can cause the wearing and tearing of roller, and meeting and belt generation slippage unavoidably, when using contactless speed pickup, if the speed of belt feeder is monitored in real time, just abundant magnetic must be set on belt, not only increased manufacturing cost, and maintenance capacity can strengthen also.
Summary of the invention
For solving existing belt conveyor speed pickup knot magnetic too much problem is set, the utility model provides a kind of belt conveyor speed pickup, and this device has characteristic of simple structure.
The technical solution adopted in the utility model is: a kind of belt conveyor speed pickup, comprise magnetic and the signal receiver that is mated, two is that the magnetic of symmetric points is contained on the changed course cylinder former with changed course centre of the drum, and the signal receiver probe is contained on the support in the changed course cylinder former outside.
This device is measured the linear velocity of belt by the rotating speed of measuring cylinder, after the belt feeder running, magnetic sends pulse along with the changed course cylinder rotates continuously to the signal receiver probe, the signal that signal receiver probe will receive is transferred to the controller of belt conveyor and handles, and can draw the rotating speed of changed course cylinder by the used time of popping one's head in according to the distance between two magnetics and two magnetics.
Compared with prior art, the magnet steel of the belt conveyor speed pickup that the utility model provides is installed on the changed course cylinder, and a changed course cylinder only need be installed two magnet steel, and it is simple in structure, low cost of manufacture and easy to maintenance.
Description of drawings
Fig. 1 is the utility model belt magnetic and signal receiver scheme of installation.
Fig. 2 is the scheme of installation of the utility model magnetic on the changed course cylinder.
Among the figure, the 1-magnetic; The 2-signal receiver; The 3-cylinder that alters course.
Embodiment
A kind of belt conveyor speed pickup that the utility model provides, as shown in Figure 1, 2, comprise magnetic 1 and the signal receiver 2 that is mated, two is that the magnetic 1 of symmetric points is contained on changed course cylinder 3 formers with changed course cylinder 3 centers, and signal receiver 2 probes are contained on the support in the changed course cylinder 3 formers outside.Magnetic 1 commonly used is a magnet steel, and signal receiver 2 also is connected with amplifier, voltage comparator circuit etc.
During installation, be that symmetric points are provided with magnetic 1 with the centre of the drum on the breadth of changed course cylinder 3 earlier, magnetic 1 is a circumference with the track of cylinder operation, and signal receiver 2 probes should be aimed at this circumference.
For the ease of installing and intuitive display, between magnetic 1 is popped one's head in signal receiver 2 apart from 30mm～40mm.
Claims (2)
1. belt conveyor speed pickup, the signal receiver (2) that comprises magnetic (1) and be mated, it is characterized in that: two is that the magnetic (1) of symmetric points is contained on changed course cylinder (3) former with changed course cylinder (3) center, and signal receiver (2) probe is contained on the support in changed course cylinder (3) the former outside.
2. belt conveyor speed pickup according to claim 1 is characterized in that: between magnetic (1) and the signal receiver probe (2) apart from 30mm～40mm.
