Description

Technical Field

[0001] The present application relates to the technical field of chain tensioners, and in particular to a tension detection device for chain tensioners. Background Art

[0002] The wire tensioner, also known as the ratchet tensioner, is used to tighten the wire during the construction of overhead line installation. When using it, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm, clamp the wire with the wire clamp, and then turn the special wrench. Due to the anti-reversal effect of the ratchet, gradually wind the wire rope or galvanized iron wire around the ratchet drum to tighten the wire. Fix the tightened wire on the insulator. Then loosen the ratchet first to loosen the wire rope or galvanized iron wire, then loosen the wire clamp, and finally wind the wire rope or galvanized iron wire around the ratchet drum.

[0003] At present, the tension detection of the chain tensioner is carried out by directly dividing the tensioner into two parts, and the two divided parts are respectively connected to the two ends of the tension detection device, so that the overall force limit of the tensioner depends on the tensile strength of the tension detection device, which will reduce the strength of the overall structure of the tensioner. Utility Model Content

[0004] Based on this, it is necessary to provide a tension detection device for a chain tensioner to address the problem of low overall structural strength of a traditional chain tensioner.

[0005] The present application provides a tension detection device for a chain tensioner, comprising:

[0006] A connecting assembly is arranged between the first lifting ring and the tensioner body, the first lifting ring is rotatably connected to the top of the connecting assembly, and the bottom of the connecting assembly is bolted to the tensioner body;

[0007] A tension sensor is arranged at the bottom of the first lifting ring, and the tension sensor is fixedly connected to the connecting assembly, and the tension sensor is also fixedly connected to the tensioner; when the first lifting ring is pulled, the working surface at the top of the tension sensor feels the tension through the connecting assembly, and when the second lifting ring is pulled, the working surface at the bottom of the tension sensor feels the tension through the tensioner body.

[0008] The present application relates to a tension detection device for a chain tensioner, which ensures the load-bearing stability of the tension detection device for the chain tensioner of the present application by arranging a connecting assembly for connecting a first lifting ring and a tensioner body, and connects the top of a tension sensor to the connecting assembly through bolts, and connects the bottom of the tension sensor to the tensioner body through bolts, so that when the tension sensor detects the tension of a heavy object carried on a second lifting ring at the bottom, the device as a whole can be prevented from being disconnected when the tension sensor is damaged, based on the fact that the connecting assembly can be relatively movable relative to the tensioner body.

When the first lifting ring 13 is pulled, the working surface at the top of the tension sensor 16 senses the tension through the connecting assembly 15, and when the second lifting ring 14 is pulled, the working surface at the bottom of the tension sensor 16 senses the tension through the tensioner body 11.

[0025] Specifically, the first lifting ring 13 is rotatably connected to the top of the connecting component 15, and the first lifting ring 13 is connected to the tensioner body 11 through the connecting component 15, and the connecting component 15 and the tensioner body 11 are connected by bolts, and the connecting component 15 and the tensioner body 11 can move a certain distance relative to each other, and the second lifting ring 14 is arranged at the bottom of the tensioner body 11, and the second lifting ring 14 is connected to the tensioner body 11 through the ring chain 12, the top of the tension sensor 16 is connected to the connecting component 15 by bolts, and the bottom of the tension sensor 16 is connected to the tensioner body 11 by bolts.

[0026] In this embodiment, a connecting component 15 is provided to connect the first lifting ring 13 and the tensioner body 11, so as to ensure the load-bearing stability of the tension detection device for the chain tensioner of the present application, and on the basis that the connecting component 15 can be relatively movable relative to the tensioner body 11, the top of the tension sensor 16 is connected to the connecting component 15 by bolts, and the bottom of the tension sensor 16 is connected to the tensioner body 11 by bolts, so that when the tension sensor 16 detects the tension of the heavy object carried on the second lifting ring 14 at the bottom, it can also prevent the entire device from being disconnected when the tension sensor 16 is damaged.

The first connecting plate 151 and the second connecting plate 152 are fixedly connected to the third connecting plate 153 by bolts. The first lifting ring 13 is rotatably connected to the third connecting plate 153.

[0031] Specifically, the first connecting plate 151 and the second connecting plate 152 are connected by the third connecting plate 153 therebetween, thereby forming the main body of the connecting assembly 15, the first lifting ring 13 is rotatably connected to the third connecting plate 153, and the first connecting plate 151 and the second connecting plate 152 are movably connected to the tensioner body 11 through bolts.

[0032] In this embodiment, the first connecting plate 151 and the second connecting plate 152 are movably connected to the tensioner body 11 through bolts so that the entire connecting assembly 15 can be moved relative to the tensioner body 11 by a certain distance.

[0033] like Figure 3 As shown, in one embodiment of the present application, the tension detection device for the chain tensioner further includes a first protective plate 17 and a second protective plate 18 .

[0034] The first protective plate 17 is disposed between the first connecting plate 151 and the second connecting plate 152. The top of the first protective plate 17 is disposed close to the bottom of the third connecting plate 153. The bottom of the first protective plate 17 extends into the tensioner body 11. The first protective plate 17 is disposed between the first connecting plate 151 and the tension sensor 16.

[0040] In this embodiment, the tension sensor 16 is protected by providing a first protective plate 17 and a second protective plate 18 so that even if the tension sensor 16 breaks due to overload or damage, the protective plate can still protect the tension sensor 16 and prevent the heavy object from falling.

[0041] like Figures 1 to 3 As shown, in one embodiment of the present application, the tension detection device for the chain tensioner further includes a first positioning pin 19 and a second positioning pin 20 .

[0042] The first positioning pin 19 passes through the first connecting plate 151 , the first protective plate 17 , the tension sensor 16 , the second protective plate 18 , and the second connecting plate 152 in sequence to fasten the first connecting plate 151 , the first protective plate 17 , the tension sensor 16 , the second protective plate 18 , and the second connecting plate 152 .

[0043] The second positioning pin 20 is fixedly disposed on the tensioner body 11. The first positioning pin 19 passes through the first protection plate 17, the tension sensor 16 and the second protection plate 18 in sequence to fasten the first protection plate 17, the tension sensor 16 and the second protection plate 18.
