Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment one, by Figure 1 The present application relates to a kind of tension detection device for rigging, including base 1, the upper side of base 1 is equipped with hook 4, the outer side of hook 4 is equipped with clamping mechanism 2 and limiting mechanism 3.

[0024] Specifically, by Figures 2-3The clamping mechanism 2 includes a vertical round rod 201 located above the base 1. Both ends of the vertical round rod 201 are fixedly connected to upright plates 202, which are both fixed to the top of the base 1. A hook 4 is located between the two upright plates 202. A guide post 204 is fixedly connected between the two upright plates 202, and the hook 4 hooks onto the guide post 204. Two guide plates 203 are symmetrically and movably sleeved on the outer side of the guide post 204. Clamping plates 2015 are fixedly connected to the sides of the two guide plates 203 that are close to each other. The hook 4 is located between the two clamping plates 2015. A lifting plate 208 located above the hook 4 is movably sleeved on the outer side of the vertical round rod 201. A top sleeve block 207 is fixedly sleeved on the middle of the outer side of the vertical round rod 201. The bottom of the top sleeve block 207 is flush with the lifting plate 208. A lifting cylinder 206 is fixedly installed between the top and bottom. A tension gauge 205 is installed at the bottom of the lifting plate 208. A hook 4 is hung on the tension gauge 205. A double-acting screw 209 is provided below the hook 4. The double-acting screw 209 is rotatably connected between the two vertical plates 202. Two screw nuts 2014 are symmetrically threaded on the outer side of the double-acting screw 209. Two guide plates 203 are fixed to the top of the two screw nuts 2014 respectively. A drive motor 2011 is fixedly installed on the top of the base 1. A drive shaft 2012 is fixedly connected to the drive motor 2011. A drive bevel gear 2010 is fixedly connected to the top of the drive shaft 2012. A driven bevel gear 2013 is fixedly installed on the outer side of the double-acting screw 209. The driven bevel gear 2013 meshes with the drive bevel gear 2010.

[0025] In operation, the hook 4 is first hooked onto the guide post 204, and the guide post 204 is hung on the tension gauge 205. Then, the drive motor 2011 is started, which drives the drive shaft 2012 to rotate and drives the drive bevel gear 2010 to rotate. Since the drive bevel gear 2010 is meshed with the driven bevel gear 2013, it drives the double-acting screw 209 to rotate. Then, through the two nuts 2014, the two guide plates 203 are driven to slide along the guide post 204. At the same time, the two clamping plates 2015 move closer to each other until they clamp the hook 4 to prevent the hook 4 from rotating and to ensure the stability of the hook 4. Finally, the lifting cylinder 206 is started, which drives the lifting plate 208 to slide upward along the vertical rod 201. The tension gauge 205 pulls the hook 4 to realize the tension detection of the hook 4.

[0026] Specifically, by Figure 4 The limiting mechanism 3 includes a horizontal round rod 301 fixed between two upright plates 202. A sliding plate 304 is movably sleeved on the outer side of the horizontal round rod 301. A limiting frame 306 is fixedly installed on the side of the sliding plate 304 near the hook 4. A limiting roller 305 that abuts against the hook 4 is rotatably connected to the inner side of the limiting frame 306. A side sleeve block 302 is fixedly sleeved on the middle of the outer side of the horizontal round rod 301. A limiting cylinder 303 is fixedly installed between the side sleeve block 302 and the sliding plate 304.

[0027] In use, first, the limiting cylinder 303 is started to drive the sliding plate 304 to slide along the horizontal round rod 301, and drive the limiting frame 306 to move horizontally, and the limiting roller 305 moves until abutting with the hook 4, so as to limit the hook 4 to avoid loosening, and finally further improve the stability of the hook 4.
