The intelligence spiral tensioning device
Technical field
The utility model relates to a kind of tightening device, relates in particular to a kind of intelligent spiral tensioning device.
Background technology
For guaranteeing that belt conveyer moves safely and reliably, each bar conveyer all is furnished with tightening device.Its pattern has the weight tensioning, hydraulic tensioning, spiral tensioning etc.
Spiral tensioning device of the prior art when the tensioning load-transfer device, can not show the size of tensile force, if tensile force is too small, load-transfer device will skid; If tensile force is excessive, can make the stressed increasing of cylinder again, reduce its service life, even the phenomenon of off-axis occurs.
The utility model content
The purpose of this utility model provides a kind of intelligent spiral tensioning device that can show the size of tensile force.
The purpose of this utility model is achieved through the following technical solutions:
Intelligent spiral tensioning device of the present utility model, comprise support, described support is provided with leading screw, slide rail, described slide rail is provided with balladeur train, described balladeur train is provided with belt tensioning drum, be engaged with nut on the described leading screw, described nut is fixed on the base, is fixed with the pressure sensor of band read-out on the described base;
The contact of described pressure sensor contacts with the face of described balladeur train towards tension direction.
The technical scheme that is provided by above-mentioned the utility model as can be seen, intelligent spiral tensioning device described in the utility model, owing between base and balladeur train, pressure sensor has been installed, by pressure sensor the size of tension value is passed to read-out, can show the size of tensile force.
Description of drawings
Fig. 1 is the structural representation of the utility model intelligence spiral tensioning device specific embodiment.
The specific embodiment
Intelligent spiral tensioning device of the present utility model, its preferable specific embodiment as shown in Figure 1, comprise support, support is provided with leading screw 1, slide rail, slide rail is provided with balladeur train 2, and balladeur train 2 is provided with belt tensioning drum, is engaged with nut 3 on the leading screw 1, nut 3 is fixed on the base 4, is fixed with the pressure sensor 5 of band read-out on the base 4;
The contact of pressure sensor 5 contacts with the face of balladeur train 2 towards tension direction.Balladeur train 2 can be provided with steel plate towards the face of tension direction, and the contact of pressure sensor 5 contacts with steel plate.
Pressure sensor can also be connected with autoalarm.
The intelligent spiral tensioning device that embodiment among Fig. 1 represents is the take-up device of belt conveyer, and balladeur train 2 is provided with the belt tensioning drum of load-transfer device 6.
Concrete intelligent spiral tensioning device of the present utility model also can be used for bucket elevator, apron conveyor, chain-linked conveyer etc.Also can be used for the various slack-free mechanical equipments of spiral that adopt.
The utility model intelligence spiral tensioning device has been installed pressure sensor on base, by sensor the size of tension value is passed to read-out, can also be transferred to centralized control room to signal, directly the operational situation of conveyer is monitored.In use, the upper and lower bound of predeterminable tension value breaks bounds as tension value, and this device can auto alarm.
Its principle of work is as follows: during tensioning load-transfer device 6, rotational lead screw 1 drives base 4 by the nut on the leading screw 13 and moves, thereby compaction pressure sensor 5 makes balladeur train 2 drive roller shifting.Sensor delivery pressure number signal is to read-out.Make the contact of the sensor 5 of balladeur train 2 steel plates and pressure produce pressure by pretension leading screw 1, possess accurate demonstration force value and accident alarming function.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
