[0002] A tower crane is a lifting device commonly used in the building and construction industries. It can lift heavy objects vertically and move them horizontally within a certain range. A tower crane is usually composed of a base tower, a tower arm, and a lifting device. The lifting device includes a winch, a cable, a hook, etc. The heavy objects are lifted by the hook to complete the movement of heavy materials.

[0003] Since materials are usually loose parts and cannot be directly hooked up by a hook, they are generally loaded into storage equipment such as a hanging basket, and the basket is used to lift the materials to move them, so as to prevent the materials from spilling during transportation and causing safety accidents. However, it is not easy to hook the hook directly on the hanging basket, and it is not easy to maintain balance, and it is also easy to cause damage to the hanging basket. Therefore, a lifting rope is usually installed between the two ends of the hanging basket, and the hook is hooked on the lifting rope to lift the hanging basket. Since materials are usually loose parts, they are not balanced in the hanging basket, which causes the hanging basket to tilt after being lifted under the action of gravity. The hanging basket with a low center of gravity in the air is easily affected by high-altitude winds, which can easily cause safety accidents. Summary of the invention

[0026] By arranging two fixing devices 3 on the connecting rope 2 symmetrically with respect to the center of the connecting rope 2 and fixing the two fixing devices 3 together, a small section of the connecting rope 2 at the center position is reserved in the center of the connecting rope 2, and the length of the connecting rope 2 between the two fixing devices 3 and the two sides of the hanging basket 1 will not change due to the existence of the fixing devices 3. In this way, even if the center of gravity of the cargo carried on the hanging basket 1 tilts, the tilting of the hanging basket 1 can be reduced as much as possible to avoid the danger of lifting the cargo due to the tilt.

[0027] When the two shells 31 are closed, the fixing block 34 is inserted into the fixing groove 35. The cooperation between the fixing block 34 and the fixing groove 35 can avoid relative slippage between the two shells 31, and when the two shells 31 are fixed together, the fixing seats 32 on both sides are fitted on the connecting rope 2, and the push piece 33 can push the two fixing seats 32 closer to each other, thereby fixing the fixing seat 32 and the connecting rope 2 together. The cooperation between the limiting rod 36 and the limiting groove 37 can limit the fixing seat 32 to prevent the fixing seat 32 from detaching from the shell 31, and limit the sliding direction of the fixing seat 32 to avoid deviation and the inability to fix. By rotating the knob 8, the arc plate 4 will be inserted into the arc groove 5 on the surface of the shell 31 on the other side, so that the shells 31 on both sides can be fixed together by the arc plate 4, which is convenient for use.

[0028] The push member 33 includes a push rod 331 arranged in the casing 31, and one end of the push rod 331 located in the casing 31 is provided with a push plate 332 in contact with the fixed seat 32; by pushing the push rod 331 to move inward, the push plate 332 moves the fixed seat 32 toward the direction of the connecting rope 2, so that the fixed seat 32 can be fixed on the connecting rope 2.

A plastic buckle 337 for fixing the rotating handle 336 is provided on the surface of the casing 31. When the rotating handle 336 and the rotating shaft 334 are rotated, the pear-shaped block 335 will also rotate together, and the pear-shaped block 335 will push the push rod 331 to move inward, thereby achieving the effect of fixing the connecting rope 2, and the plastic buckle 337 can prevent the rotating handle 336 from rotating when not in use.

[0030] The inner surface of the fixing seat 32 is provided with a clamping groove 38 matching with the connecting rope 2 , and a clamping pad 39 in contact with the connecting rope 2 is provided in the clamping groove 38 ; the clamping groove 38 and the rubber clamping pad 39 can better fix the connecting rope 2 .

[0031] A connector 9 is provided between the ends of the casing 31 ; the two casings 31 are connected together by the connector 9 , which is convenient for use and symmetrical arrangement.

[0032] The connecting member 9 includes an inner connecting rod 901 and an outer connecting rod 902 arranged at the end of the casing 31, and a top ring 904 arranged on the connecting rope 2 is arranged between the end of the inner connecting rod 901 and the end of the outer connecting rod 902, and an insertion rod 908 is arranged on the side of the top ring 904, a connecting ring 909 is arranged at the top end of the inner connecting rod 901, and a connecting head is arranged at the top end of the outer connecting rod 902, the insertion rod 908 passes through the connecting ring 909 and is hinged with the connecting head, and a bottom ring 903 matching with the top ring 904 is arranged on the top ring 904.

[0033] The inner connecting rod 901 and the outer connecting rod 902 at the top of the shells 31 on the left and right sides are symmetrically located, that is, the shells 31 on the left and right sides are the same. After the shells 31 are put on the connecting rope 2, the top ring 904 is pulled up, so that the shells 31 will move along the connecting rope 2, and under the action of the gravity of the hanging basket 1, the two ends of the connecting rope 2 are balanced, and the connecting rope 2 will always be pressed on the end of the shell 31. In this way, under the movement of the shell 31, the pressure of the connecting rope 2 on the two shells 31 will be equal. In this way, the position of the top ring 904 between the two shells 31 is the center of the connecting rope 2. In this way, the center position of the connecting rope 2 can be determined, so as to achieve the effect of symmetrically setting the shells 31 with the center of the connecting rope 2. The top ring 904 and the bottom ring 903 are put on the connecting rope 2 to achieve a fixing effect and avoid subsequent sliding.

[0034] The top ring 904 is provided with a buckle 905, and the bottom ring 903 is provided with a slot 906 that matches the buckle 905. The bottom ring 903 and the top ring 904 are hinged; the buckle 905 and the slot 906 are used to fix the top ring 904 and the bottom ring 903 together.

[0035] The inner connecting rod 901 and the outer connecting rod 902 are hinged on the casing 31, and the bottom ring 903 is hinged on the end of the inner connecting rod 901. The bottom of the bottom ring 903 is provided with a recessed block 907 that matches the hook of the tower crane to avoid direct contact between the hook and the bottom ring 903, causing structural damage and affecting the life of the equipment.

[0036] In summary, when in use, first put the casing 31 on the connecting rope 2, and by rotating the knob 8, the arc plate 4 will be stuck into the arc groove 5 on the surface of the casing 31 on the other side, so that the casings 31 on both sides can be fixed together by the arc plate 4, and then by pulling up the top ring 904, the casing 31 will move along the connecting rope 2, and under the action of the gravity of the hanging basket 1, the two ends of the connecting rope 2 will be balanced, and the connecting rope 2 will always be pressed on the end of the casing 31, so that under the movement of the casing 31, the two casings 31 will be finally affected by the connecting rope. 2 will be equal, so that the position of the top ring 904 between the two casings 31 is the center of the connecting rope 2, so that the center position of the connecting rope 2 can be determined, and the casing 31 is symmetrically arranged with the center of the connecting rope 2. The top ring 904 and the bottom ring 903 are sleeved on the connecting rope 2 to achieve a fixing effect to avoid subsequent sliding. Finally, the handle 336 is rotated to push the push rod 331 inward through the pear-shaped block 335, thereby fixing the fixing seat 32 and the connecting rope 2 together, thereby reducing the skew of the hanging basket 1.

[0037] The technical effect of the present invention is: by arranging two fixing devices 3 on the connecting rope 2 symmetrically with respect to the center of the connecting rope 2, and fixing the two fixing devices 3 together, a small section of the connecting rope 2 at the center position is reserved at the center of the connecting rope 2, and the length of the connecting rope 2 between the two fixing devices 3 and the two sides of the hanging basket 1 will not change due to the existence of the fixing devices 3. In this way, even if the center of gravity of the cargo carried on the hanging basket 1 tilts, the tilting of the hanging basket 1 can be reduced as much as possible to avoid the danger of lifting the cargo due to the tilt.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
