Abstract
The utility model discloses a tension detecting device for mining for detecting the tension on the rubber belt of a belt conveyor and detecting the traction on a steel wire rope. The tension detecting device for mining mainly comprises a strain beam, a strain foil, a transmission circuit board and conducting wires, wherein the strain foil, the transmission circuit board and the conducting wires are arranged in the strain beam. Two guide wheels are respectively arranged at the two ends of the upper part of the strain beam. A gripping mechanism is arranged at the central part of the strain beam. The utility model has the advantages that the installation and the maintenance are convenient, the safety is reliable, the performance is superior to the similar detecting devices and the device is suitable for use under the coal well; when the detecting device works with the belt conveyor protection device, the belt tension can be detected dynamically, the device can control the rubber belt tension adjusting device of the belt conveyor to automatically adjust the tension on the rubber belt and the device enables the conveying equipment to run under ideal conditions for a long period.
Description
Technical field:
The utility model relates to a kind of mining tension detecting apparatus that detects the conveyor belt running tensile force and use rope traction power that is mainly used in.
Background technology:
Raising along with the coal mining automaticity; the belt conveyor protection requires to increase; performance is constantly perfect; the mining tension detecting apparatus that this just need be provided for detecting the conveyor belt running tensile force and use rope traction power; tension detecting apparatus in the past adopts the tensile force type structure more; when mounted; need at first open the joint of wire rope; one end of tension detecting apparatus is fixed; then, the other end is fixed on the tensioning winch wire rope, and trouble not only is installed; and fixing insecure, cause unstable properties.
The utility model content:
The purpose of this utility model is to provide a kind of mining tension detecting apparatus of side-compression structure, and during detection, not only installation and maintenance are very convenient, and dependable performance.
For achieving the above object, the utility model is taked following design proposal: a kind of mining tension detecting apparatus, be made up of strain beam and inner foil gauge, transmission circuit plate and lead thereof, it is characterized in that being provided with guide wheel in the strain beam both upper ends thereof, the strain beam middle part is provided with gripping mechanism.
The further technical scheme of the utility model is, described gripping mechanism is made up of dop, screw rod, fixed head and nut, and dop is supported by two screw rods, and fixed head is enclosed within on the screw rod, nut is positioned at the lower end of screw rod, and this gripping mechanism is fixed by fixed head and nut.
This pick-up unit adopts the side-compression structure, feel the tested material resources that cause the main body stress deformation by the foil gauge that is fixed on strain beam inside, the reacting condition of tested material resources to transmission circuit, is sent out and the proportional electric signal of the variation of power then the current signal of output DC4-20mA.
The utility model compared with prior art has following beneficial effect: when mounted, need not to open the joint of wire rope, the other end does not need to be fixed on the tensioning winch yet, as long as guide wheel is close to wire rope, with gripping mechanism wire rope is fixed getting final product then.Installation and maintenance are very convenient and safe and reliable, and performance is better than similar pick-up unit, are convenient to use under the coal mine; This pick-up unit and the supporting use of belt conveying protector can be carried out dynamic test to belt tension, and may command sealing-tape machine tension adjusting device realizes that the conveyor belt tension of sealing-tape machine regulates automatically, make conveying equipment long-time running under optimal state.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of gripping mechanism among Fig. 1.
Embodiment:
As shown in Figure 1, mining tension detecting apparatus provided by the utility model mainly is made up of strain beam 1 and inner foil gauge 11, transmission circuit plate 12 and lead 13 thereof, be provided with the guide wheel 2 of bearing detected wire rope 4 in strain beam 1 both upper ends thereof, strain beam 1 middle part is provided with gripping mechanism 3.Referring to shown in Figure 2, gripping mechanism 3 is made up of dop 31, screw rod 32, fixed head 33 and nut 34, and dop 31 is supported by two screw rods 32, and fixed head 33 is enclosed within on the screw rod 32, nut 34 is positioned at the lower end of screw rod 32, and this gripping mechanism is fixing by fixed head 33 and nut 34.
During detection, wire rope is close on the guide wheel, by gripping mechanism wire rope is fixed then, feel the tested material resources that cause strain beam main body stress deformation by the foil gauge that is fixed on strain beam inside, with the reacting condition of tested material resources to transmission circuit, send out and the proportional electric signal of the variation of power the current signal of output DC4-20mA then.
