Description

Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a connecting piece for a steel rope and an iron chain. Background Art

[0002] With the emergence of large-scale equipment, the overall weight of equipment has increased, and hoisting has developed. Some large and medium-sized cities in my country and coastal ports and docks have adopted corresponding large cranes for hoisting and transportation. When hoisting and transporting heavy equipment, it is usually necessary to use connectors to connect the iron ropes and chains.

[0003] However, traditional steel rope and iron chain connectors have certain limitations, such as simple structure, easy deformation, and easy loosening of pins. These problems not only affect the service life of the connectors, but may also threaten the safety of equipment and structures and even the lives of operators. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provides a connecting piece for a steel rope and an iron chain.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A connector for a steel rope and an iron chain comprises a connector body, wherein the connector body comprises an upper connecting frame and connecting plates symmetrically arranged at the lower side of the upper connecting frame, wherein a trapezoidal wedge for passing the steel rope is fixedly arranged in the upper connecting frame, a pin is installed between the two connecting plates, and a center of gravity adjustment component for limiting the swing amplitude of the iron chain is also arranged between the two connecting plates.

[0007] Preferably, the center of gravity adjustment assembly includes sliding grooves respectively opened on the outer sides of the two connecting plates, an adjustment slider sliding on the outer side of the connecting member body is provided between the two sliding grooves, and a locking screw that is threadedly connected to the adjustment slider and is movably opposed to the connecting member body.

[0008] Preferably, the adjusting slider comprises sliding blocks respectively slidably connected in two sliding grooves and a sliding plate for connecting the two sliding blocks, and the locking screw is threadedly arranged on the sliding plate.

[0009] Preferably, one side of the connecting plate is arranged as an arc structure, the sliding groove is arranged as an arc groove matching with the arc structure, and scale lines are arranged on the outer side of the connecting plate along the arc direction of the sliding groove.

[0010] Preferably, arc-shaped grooves for installing steel ropes are formed on both sides and the lower end of the trapezoidal wedge block.

[0011] Preferably, the upper connecting frame and the two connecting plates are welded into one piece.

[0012] Compared with the prior art, the utility model provides a connecting piece for a steel rope and an iron chain, which has the following beneficial effects:

[0013] 1. The connecting piece of the steel rope and the iron chain is adapted to the sliding groove on the connecting piece body through an adjusting slider, and the protruding part of one end of the adjusting slider is inserted into the sliding groove, so that the adjusting slider can slide along a circular arc section of the connecting piece body. By adjusting the different positions of the adjusting slider, the center of gravity of the entire connecting piece can always be relatively fixed at the same position when lifting goods of different weights, thereby solving the problem of lifting shaking caused by the change of the center of gravity brought about by the use or maintenance and disassembly of the equipment.

[0014] 2. The connecting piece of the steel rope and the iron chain can prevent the swing amplitude of the iron chain by setting an adjusting slider, so that the swing of the iron chain is controlled within a smaller range, thereby greatly reducing the probability of the pin being loose, so that the pin can be relatively stably fixed in the corresponding position, reducing the probability of safety accidents.

[0015] 3. The connecting piece of the steel rope and the iron chain adopts an isosceles trapezoidal wedge block, and arc-shaped grooves are opened on both sides and the lower end of the wedge block, so that the steel rope can be installed better and the contact area between the wedge block and the steel rope can be increased under the same pressure, which greatly reduces the pressure of the wedge block on the steel rope and prolongs the service life of the steel rope.
