The torque test device comprises a fixed frame, a screw rod, a friction force measurer, a clamping sleeve, a transmission rod and a force-applying bolt, wherein the screw rod is fixed on the fixed frame; the friction force measurer is connected with the clamping sleeve; the clamping sleeve is connected with the screw rod via the transmission rod; the to-be-tested tensioning sleeve is sleeved in the clamping sleeve; and the force-applying bolt is connected with the screw rod. Compared with the prior art, the torque test device disclosed by the utility model has the advantages of being high in measurement accuracy, convenient to operate, low in realization cost, high in reliability, and the like.
Description
Technical field
The utility model relates to a kind of staircase driving shaft dependence test device, especially relates to a kind of staircase driving shaft tensioner cover force moment testing device.
Background technology
Existing driving device of escalator comprises motor, reducer casing, main drive shaft, drive sprocket, first driven sprocket and second driven sprocket, and drive sprocket, first driven sprocket and second driven sprocket all are connected on the main drive shaft.Motor and reducer casing are given drive sprocket by chain with transmission of power, and drive sprocket drives main drive shaft and rotates, and drive two driven sprockets thus and rotate, and driven sprocket then drives component movement such as step by chain.Main drive shaft gas in driving device of escalator has arrived vital role, wherein the stiction size of the tensioner of main drive shaft cover has directly influenced the performance of main drive shaft, and therefore how the stiction of tensioner cover being tested becomes urgent problem instantly.
The utility model content
The purpose of this utility model is exactly to provide a kind of measuring accuracy height, easy to operate, the realization staircase driving shaft tensioner that cost is low, reliability is high cover force moment testing device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of staircase driving shaft tensioner cover force moment testing device, it is characterized in that, comprise fixed mount, screw rod, friction measurement instrument, gripping sleeve, drive link and application of force bolt, described screw rod is fixed on the fixed mount, described friction measurement instrument is connected with gripping sleeve, described gripping sleeve is connected with screw rod by drive link, and described tensioner to be measured is set in the gripping sleeve, and described application of force bolt is connected with screw rod;
Drive screw motion by tightening application of force bolt, screw motion drives to step up to overlap steps up, and the tensioner cover of motion is stopped, and the friction measurement instrument shows the maximum static friction force that this tensioner cover rotates.
Also comprise the base plate that is used to place fixed mount and gripping sleeve.
Compared with prior art, the utlity model has following advantage:
1, measuring accuracy height is measured by the friction measurement instrument, and with respect to testing by naked eyes in the prior art, its precision has improved a lot;
2, easy to operate, only need can finish test by tightening application of force bolt;
3, realize that cost is low, existing equipment was advanced to transform to realize this function;
4, reliability height, the parts of employing are ripe parts.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of staircase driving shaft tensioner cover force moment testing device, comprise fixed mount 1, screw rod 2, friction measurement instrument 3, gripping sleeve 5, drive link 4 and application of force bolt 6, described screw rod 2 is fixed on the fixed mount 1, described friction measurement instrument 3 is connected with gripping sleeve 5, described gripping sleeve 5 is connected with screw rod 2 by drive link 4, and described tensioner cover 8 to be measured is located in the gripping sleeve 5, and described application of force bolt 6 is connected with screw rod 2; Drive screw rod 2 motions by tightening application of force bolt 6, screw rod 2 motion drives step up to overlap 5 and step up, and the tensioner cover 8 of motion is stopped, and friction measurement instrument 3 shows the maximum static friction force that this tensioner cover rotates.
The utility model also comprises the base plate 7 that is used to place fixed mount and gripping sleeve.
