Abstract

The utility model relates to a sag measurer for conveyer belting, which comprises a contact wheel, a sliding frame, small springs, a recording pen, a large spring, recording paper, a guide bar, a magnet block, a supporting frame, etc. The utility model is characterized in that the contact wheel is installed on the upper end of the sliding frame and can move up and down along the sliding frame, the sliding frame is supported on the supporting frame by the large spring which is hollowly sleeved on the guide bar, and the lower end is positioned on the supporting frame; sag which is produced by deadweight and matter weight is directly recorded by the recording pen installed on the sliding frame, to detect the sag value of the conveyer belting in various work conditions. The utility model has the advantages of simple structure and high safety; besides the sag value is intuitionistic and accurate.

Description

Conveying belt sag detecting device

The utility model relates to a kind of conveying belt sag detecting device, is applicable to the measurement of belt of belt conveyor sag.

Belt conveyor is the major equipment that utilization has a large capacity and a wide range in the present Transport Machinery of China, be widely used in metallurgy, the mine, coal, the harbour, the power station, chemical industry, industries such as grain are to the conveying of bulk material, along with long distance, the development of the belt conveyor of large conveying quantity, problems of measurement as the conveying belt sag value of one of main performance index that guarantees the conveyor operate as normal is more and more paid attention to by people, but up to this point, also there is not conveying belt sag pick-up unit both at home and abroad, particularly the detection of dynamic transport band sag also be nobody shows any interest in, and what had only is to obtain the conveying belt pretension by Theoretical Calculation to set weight or other tensioning system with control conveying belt sag, because the working condition that conveyor uses is changeable, condition with the Theoretical Calculation hypothesis, often be difficult to coincide, make the pretension that applies in advance unreasonable, excessive as the conveying belt sag, the easy sideslip of conveying belt, scatter material and increase conveyor secondary power etc., if sag is too small, must make each parts of conveyor bear higher internal stress, cause each parts premature damage and malfunctioning, serious meeting causes stopping production.

The purpose of this utility model provides a kind of conveying belt sag detecting device, detects the sag value of conveying belt intuitively with device simply and easily, makes operating personnel can in time align the tension force of conveying belt in view of the above, to guarantee the conveyor operate as normal.

Accompanying drawing 1, conveyor sag detector arrangement sketch

The purpose of this utility model is achieved in that as shown in Figure 1, this inspection Surveying device is by wheel trolley 3, balladeur train 4, little spring 5, recording pen 6, big spring 7, note The compositions such as record paper 8, guide rod 9, magnet piece 10, support 11, the pen cap 13, this device Be installed in (or inferior division two holders of conveyer middle frame 12 and top set's two carrying idlers 2 Roller) place in the middle of.

Among the figure, 1 is conveying belt, and 2 is carrying roller, A ₀Be the distance between two carrying rollers, H ₀Be the height of recording pointer center line to the wheel trolley top, H _aFor the recording pointer center line to support bottom surface height, H is carrying roller top to a support bottom surface height, H _bThe bracket bottom plate thickness.

A kind of conveying belt sag detecting device, comprise wheel trolley 3, balladeur train 4, little spring 5, recording pointer 6, big spring 7, recording chart 8, guide rod 9, magnet piece 10, support 11, the pen cap 13, bearing 14, it is characterized in that: wheel trolley 3 is installed on the balladeur train 4 on the end bearing 14, balladeur train 4 is installed on the support 11 by big spring 7 supportings, big spring 7 skies are enclosed within on the guide rod 9, recording pointer 6 is installed on the pen cap 13, the pen cap 13 is welded on balladeur train 4 upper sides, magnet piece 10 is contained on support 11 side plates, recording chart 8 is pressed solidly on support 11 side plates by magnet piece 10, and little spring 5 is housed in the pen cap 13, and little spring 5 one ends are located in the pen cap 13, one end and recording pointer 6 link, supporting recording pointer 6.The tension force of big spring should keep wheel trolley often to contact with conveying belt, and the tension force of little spring should guarantee that writing point contacts with recording chart all the time.

The embodiment of this utility model is: when conveyor moves, conveying belt 1 is under its certainly vertical (zero load) or weight of material effect, and a sagging distance (sag) keeps often contacting with conveying belt 1 owing to wheel trolley 3, also give 3 one acting forces of wheel trolley simultaneously, the wheel trolley 3 stressed drive balladeur train 4 compression big springs 7 that move down move down same distance, recording pointer 6 also moves same distance with balladeur train 4, like this in the sag value of just directly having write down on the recording chart 8 under this condition, when weight of material changes, the power that acts on the wheel trolley 3 changes, conveying belt 1 sag also changes thereupon, recording pointer will be noted the sag value under the various operating modes at any time on removable recording chart 8, operating personnel check and in time adjust the operate as normal of the tension force of conveying belt 1 with the assurance conveyor according to predetermined sag value scope.

The utility model is simple in structure, processing ease, safe and reliable, the sag value of surveying directly perceived accurately, applicability is strong, be easy to promote.
