[0003] But the steel wire rope of the present use, after being received and released, since the steel wire rope has hardness, the steel wire rope cannot be restored to the tension state of the original steel wire rope after being received and released, and problems such as loose steel wire rope, tightness or not, etc. may occur, resulting in unstable steel wire rope protection system and increased maintenance cost. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a kind of agricultural steel wire rope system tension self -balancing device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: a kind of agricultural steel wire rope system tension self -balancing device, including steel wire rope, column and gravity support, the gravity support is fixed on the two sides of column by clamp, the upper end of gravity support is fixed with at least 1 group of fixed pulley block, the steel wire rope passes through fixed pulley block, and a movable pulley is further provided between fixed pulley block, a hanging ring is provided at the lower end of movable pulley, and a counterweight is hung below the hanging ring by rope.

[0006] Further, the gravity support is two respectively fixed on the two sides of column.

[0007] Further, the fixed pulley block includes two groups, respectively fixed on gravity support.

[0008] Further, each fixed pulley block includes two fixed pulleys.

[0009] Further, the column is a square column.

[0010] Further, the counterweight is two, arranged on the two sides of square column.

[0011] Further, the rope between the counterweight and the hanging ring is fixedly connected by the clamp at both ends.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model reduces the tension of the wire rope by passing the wire rope through one movable pulley and two fixed pulleys fixed on the column, and enhances the ability of the wire rope to return to its original tension after being wound up and unwound by configuring a load-bearing block of appropriate weight under the movable pulley. After being wound up and unwound, the wire rope basically returns to its original tension, solving the problems of the wire rope not being able to be wound up or pulled out after being wound up and unwound.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-2 As shown, an agricultural wire rope system tension self-balancing device includes a wire rope 8, a column 7, and a gravity support 3. The gravity support 3 is fixed to both sides of the column 7 by clamps 4. At least one set of fixed pulleys 2 is fixed to the upper end of the gravity support 3. The wire rope 8 passes through the fixed pulleys 2, and a movable pulley 1 is also passed between the fixed pulleys 2. A hanging ring 9 is provided at the lower end of the movable pulley 1, and a counterweight 6 is hung below the hanging ring 9 by a rope.

[0018] During installation: the column 7 is a square column, the gravity support 3 consists of two fixed on both sides of the column 7, the fixed pulley 2 consists of two sets, each set of fixed pulleys consists of two fixed pulleys fixed on two gravity supports 3, the counterweight 6 consists of two, arranged on both sides of the square column, and the two ends of the rope between the counterweight 6 and the hanging ring 9 are fixedly connected by the clamp 5 (model M8 clamp).

[0019] In practical use, the wire rope is passed sequentially through one fixed pulley, one movable pulley, and one fixed pulley (each fixed pulley group includes two fixed pulleys fixed to two gravity supports respectively). The wire rope passes through one movable pulley and two fixed pulleys fixed on the column to reduce the tension of the wire rope. By placing a load-bearing block of appropriate weight under the movable pulley, the ability of the wire rope to return to its original tension after being wound up and unwound is enhanced. After being wound up and unwound, the wire rope basically returns to its original tension, solving the problems of the wire rope not being able to be wound up or pulled out after being wound up and unwound.
