Description

Technical Field

[0001] The invention relates to the technical field of chain detection, and in particular to a metal chain tension force detection device. Background Art

[0002] A chain is a strip or ring-shaped part supported by metal, which is mostly used for mechanical transmission and traction. According to different functions, chains can be roughly divided into four categories: transmission chain, conveyor chain, traction chain and special chain. No matter what kind of chain, it needs to bear a certain tension when working, which requires the chain to have a certain strength to maintain normal operation. Therefore, the tension of the chain needs to be tested before the chain is produced and shipped out of the factory; when testing the tension of the chain, it is necessary to first preliminarily tension the chain so that the chain is in a straight state, and then apply different external forces to the chain to observe the surface and internal stress of the chain under the action of external forces, so as to detect the tension of the chain. The chain tension detection device in the prior art usually only selects one part of the chain for detection, and the detection comprehensiveness is poor, the detection effect is general, and it is impossible to perform a comprehensive detection of the chain inside and outside.

[0006] Furthermore, two cameras are fixedly mounted on the bottom plate, respectively located above and below the chain.

[0007] When in use, the chain is put on the outside of the two sprockets, and then the handle is manually turned to drive the screw column to rotate, thereby driving the internal thread block to descend, thereby pulling the two slides to slide outward through the side rotating rod, the side spring is compressed, and the chain is tensioned through the sprocket.

[0008] The X-ray machine emits rays that penetrate the chain and form an image on the receiving plate, thereby detecting whether there are cracks inside the chain. The camera is used to detect the upper and lower surfaces of the chain to detect whether there are cracks on the surface of the chain.

[0011] The rotation of the toggle motor drives the motor gear and the output bevel gear to rotate, thereby driving the side bevel gear and the transmission shaft to rotate. The motor gear drives the lower gear, the gear column and the upper gear to rotate, thereby driving the toggle gear and the toggle sprocket to rotate.

[0015] The rotation of the transmission shaft drives the convex ball to rotate, thereby driving the inner bidirectional threaded sleeve and the pulley to reciprocate, thereby driving the vertical frame and the pressure slide to reciprocate, and the chain is squeezed and pressure is applied through the pressure wheel. When the pressure wheel contacts the chain, the pulley continues to move inward, the strong spring is compressed, and as the pressure slide slides along the vertical frame, the pointer gear and the pointer are driven to rotate under the action of the fixed rack, and the applied pressure is obtained through the pressure scale line on the pointer and the end frame.

[0031] When in use, the chain 4 is put on the outside of the two sprockets 110, and then the rotating handle 105 is manually turned to drive the screw column 104 to rotate, thereby driving the internal thread block 106 to descend, thereby pulling the two slides 108 to slide outward through the side rotating rod 107, and the side spring 111 is compressed to tighten the chain 4 through the sprocket 110.

[0041] The working principle of the metal chain tension force detection device disclosed in the present invention is as follows: when in use, the chain 4 is sleeved on the outside of the two sprockets 110, and then the rotating handle 105 is manually rotated to drive the screw column 104 to rotate, thereby driving the internal thread block 106 to descend, thereby pulling the two slides 108 to slide outward through the side rotating rod 107, and the side spring 111 is compressed, and the chain 4 is tensioned through the sprocket 110.

When the chain 4 is tensioned, the toggle sprocket 212 is inserted into the chain 4, and the toggle sprocket 212 rotates to drive the chain 4 to move. The rotation of the transmission shaft 206 drives the convex ball 312 to rotate, thereby driving the inner two-way threaded sleeve 303 and the pulley 301 to reciprocate, thereby driving the stand 304 and the pressure slide 305 to reciprocate, and the chain 4 is squeezed and pressure is applied through the pressure wheel 309. When the pressure wheel 309 contacts the chain 4, the pulley 301 continues to move inward, and the strong spring 307 is compressed. As the pressure slide 305 slides along the stand 304, the pointer gear 311 and the pointer 310 are driven to rotate under the action of the fixed rack 306, and the applied pressure is obtained through the pressure scale line on the pointer 310 and the end frame 313. By replacing different strong springs 307, the chain 4 can be tested with different pressures, and the chain 4 can be tested repeatedly in conjunction with the movement of the chain 4.
