The bridge and portal crane are used as special equipment, and have special technical standards and strict safety requirements for use and maintenance of the special equipment. The replacement of the steel wire rope for the bridge and the portal crane is an important content in daily maintenance work of hoisting equipment, wherein the connection and the installation of the wedge-shaped joint on the steel wire rope and the balance arm and the fixation of the steel wire rope clamp are extremely important, and the connection and the installation of the wedge-shaped joint on the balance arm are related to the stable and safe hoisting work of the crane. If the connection between the steel wire rope and the wedge-shaped joint is not firm, the safety technical requirement is not met, and serious safety accidents are easy to occur in the production process. The wedge-shaped connector on the balance arm of the bridge and portal crane mainly comprises a wedge sleeve, a wedge block and a fixed steel wire rope clip, when the steel wire rope is connected with the wedge-shaped connector for installation, firstly, a new steel wire rope to be replaced passes through the wedge sleeve, then the wedge block is clamped into the wedge sleeve to be straightened and fastened together with the penetrated steel wire rope, so that the wedge block is tightly clamped in the wedge sleeve, and finally, the steel wire rope clip is arranged at the position of the steel wire rope from the wedge sleeve for fixing, thereby realizing firm connection between the steel wire rope and the wedge-shaped connector, and ensuring that the steel wire rope does not loose and slide in the lifting operation process of the crane. For a large-tonnage bridge crane, because the weight of the lifted goods is large, a steel wire rope with a thicker diameter is needed to meet the use requirement. The diameter of the steel wire rope directly determines the replacement difficulty, and the larger the diameter is, the larger the hardness is, and the harder the steel wire rope is bent to be fastened to a degree reasonably meeting the requirement. After the large-diameter steel wire rope passes through the wedge sleeve, the steel wire rope is bent to a certain extent, and the steel wire rope and the wedge block are difficult to continuously clamp and fasten due to the bending resistance of the steel wire rope and the friction between the steel wire rope and the inner wall of the wedge sleeve, so that a large gap exists between the steel wire rope and the wedge block, and the safety use requirement cannot be met. A special method or special tool is needed to tighten the steel wire rope, ensure that the steel wire rope is tightly matched with the wedge block and is firmly clamped in the wedge sleeve, and the steel wire rope does not slide in the use process, so that the crane can stably and safely run. The existing method for connecting the steel wire rope and the wedge-shaped joint in bridge and portal crane maintenance departments is a forklift and man-matched installation method. Although the connection method can achieve the aim of connecting the steel wire rope and the wedge-shaped connector together, the connection method is limited by a working site, more importantly, the requirement of maintenance safety cannot be met, because the forklift and the person cooperate in the installation operation of the steel wire rope and the wedge-shaped connector, the operator is in close contact with the motorized forklift, and the safety risk is very high, and accidents cannot be avoided, so that the connection method of the steel wire rope and the wedge-shaped connector, which is currently used, has the defect that a more proper connection method of the steel wire rope and the wedge-shaped connector needs to be found.
The patent number is CN201610501869.3, and the patent name is 'an installation tool for installing a steel wire rope into a wedge-shaped joint', and the installation tool for installing the steel wire rope into the wedge-shaped joint comprises a retainer, a pull rod, a steel wire rope clamp and a pin shaft. The clamping device has the advantages that the structure is simple, the operation is easy, the clamping force is strong, the steel wire rope clamping device is designed to automatically clamp, the steel wire rope clamping device is not easy to slip, the rubber plate is arranged on the clamping surface of the clamping device, the clamping injury of the steel wire rope is effectively prevented, the clamping surface of the clamping device is designed to be open, clamping and stretching can be performed as long as the two clamping surfaces can accommodate the steel wire rope, and the tensioning and the installation of the steel wire ropes with different diameters can be met.
