Description

Technical Field

[0001] The utility model relates to the technical field of rigging, in particular to a controller for automatically adjusting the tension of rigging. Background Art

[0002] There are two main types of rigging: metal rigging and synthetic fiber rigging. Rigging refers to the equipment used with ropes and cables, such as hooks, relaxers, rope clamps, thimbles, shackles, etc., collectively known as rigging. Some people also classify ropes as rigging. There are two main types of rigging: metal rigging and synthetic fiber rigging. It is a general term for masts, crossbars, sail feet, gaff and all ropes, chains and the tools used to operate them.

[0003] An automatic rigging tension controller is required during the use of rigging. After searching, it is found that the tension of the rigging in the prior art is generally fixed and difficult to adjust. When the lifting environment and space change, rigging of different specifications needs to be reused, and rigging of different specifications needs to be frequently replaced, which is very time-consuming and labor-intensive, thereby reducing the practicality of the rigging and failing to meet the use requirements. When lifting heavy objects, the lifting rigging will swing due to the inertia of the heavy objects themselves. It is necessary to adjust the tension of the lifting rigging to disperse the energy to both sides of the rigging as much as possible to achieve the purpose of adjusting the tension and protection. Therefore, an automatic rigging tension controller is proposed to solve the above-mentioned problems. Utility Model Content

The tension adjustment mechanism 6 includes a hydraulic cylinder 61 fixedly installed inside the installation box 2, and a mounting frame 62 is fixedly connected to the output end of the hydraulic cylinder 61. The interior of the mounting frame 62 is rotatably connected to a pulley 63, and the traction rope 4 is transmission-connected to the outside of the pulley 63.

[0024] The controller starts the extension and retraction of the two hydraulic cylinders 61, which drives the two mounting frames 62 to move left and right. The two mounting frames 62 drive the pulley 63 to move left and right. The left and right movement of the pulley 63 facilitates the adjustment of the tension of the traction rope 4, thereby adapting to the lifting of heavy objects with different gravities, and avoiding possible damage to the equipment during the lifting process, thereby achieving the advantages of easy tension adjustment and strong practicality.

[0025] The two hydraulic cylinders 61 are symmetrically distributed inside the installation box 2 , and a mounting seat adapted to the hydraulic cylinders 61 is fixedly installed inside the installation box 2 .

[0026] In addition, the opening of the hook 5 is rotatably connected to an elastic buckle. The hook 5 belongs to conventional technology known to the public in the prior art, so its specific structure and working principle will not be described in detail in this article.

[0027] In this embodiment, the buffer assembly 7 includes a sleeve 71 fixedly connected to the top of the installation box 2, a mounting block 72 fixedly connected to the inner bottom wall of the sleeve 71, an elastic telescopic rod 73 fixedly connected to the top of the mounting block 72, a connecting block 74 fixedly connected to the top of the elastic telescopic rod 73, a telescopic block 76 extending to the outside of the sleeve 71 fixedly connected to the top of the connecting block 74, a connecting rod 77 fixedly connected to the top of the telescopic block 76, a spring 75 fixedly connected between the mounting block 72 and the connecting block 74, and the fixed pulley 3 is arranged on the top of the connecting rod 77. By providing the elastic telescopic rod 73 and the spring 75, the fixed pulley 3 effectively plays a shock-absorbing and buffering role when transmitting the traction rope 4, thereby preventing large vibrations from occurring during the lifting and placement of the equipment.

[0028] The mounting block 72 and the connecting block 74 are both solid rectangular parallelepipeds, and the spring 75 is connected to the outside of the elastic telescopic rod 73 .

The interior of the sleeve 71 is provided with a sliding groove that is compatible with the sliders 78. The sliders 78 and the sliding groove are slidably connected. The provision of the sliders 78 and the sliding groove improves the stability of the fixed pulley 3 during buffering.

[0031] In this embodiment, a limiting mechanism 8 for limiting the position of the traction rope 4 is provided on the outside of the installation box 2. The limiting mechanism 8 includes a fixing plate 81 fixedly connected to the bottom of the installation box 2. An electric push rod 82 is fixedly connected to the outside of the fixing plate 81. A limiting seat 83 is fixedly connected to the output end of the electric push rod 82. The traction rope 4 is slidably connected to the inside of the limiting seat 83. The electric push rod 82 is activated by the controller to extend and retract, and the electric push rod 82 extends and retracts to drive the limiting seat 83 to move left and right, thereby facilitating the limiting processing of the traction rope 4 after the tension is adjusted, and preventing the traction rope 4 from shaking significantly when driving the hook 5 and the heavy object to move, thereby achieving the advantage of strong practicality.

[0032] In this embodiment, four fixing columns 9 are fixedly connected between the positioning base 1 and the installation box 2 . The four fixing columns 9 are distributed between the positioning base 1 and the installation box 2 in a rectangular shape.

[0033] The working principle of the above embodiment is:

[0034] When in use, the two hydraulic cylinders 61 are activated by the controller to extend and retract, and the extension and retraction of the two hydraulic cylinders 61 drive the two mounting frames 62 to move left and right, and the two mounting frames 62 drive the pulley 63 to move left and right. The left and right movement of the pulley 63 adjusts the tension of the traction rope 4, thereby adapting to the lifting of heavy objects with different gravities, and also avoiding possible damage to the equipment during the lifting process. By setting the elastic telescopic rod 73 and the spring 75, the fixed pulley 3 effectively plays a shock-absorbing and buffering role when transmitting the traction rope 4, avoiding large vibrations of the equipment during the lifting and placement process, and by setting the slider 78 and the slide groove, the fixed pulley 3 can be stably buffered; when limiting the traction rope 4, the electric push rod 82 is activated by the controller to extend and retract, and the electric push rod 82 extends and retracts to drive the limit seat 83 to move left and right, thereby limiting the traction rope 4 after the tension is adjusted.
