Suspended beam type hanger component and crane using same

Abstract

The invention discloses a suspended beam type hanger component and a crane using the same. The suspended beam type hanger component comprises a load-bearing cross beam extending leftwards and rightwards, a carrier arranged on the load-bearing cross beam and used for carrying lifted objects, and a guide limiting device for preventing the carrier from swaying, wherein the guide limiting device comprises two vertical guide rods which are upwards suspended on the load-bearing cross beam at an interval from left to right, guide beams which are used for being fixedly arranged on a main beam of the crane and are parallel to the guide rods are arranged on the front side and the back side of each guide rod, guide wheels spaced vertically are arranged between each guide beam and each guide rod, are rotatablely assembled on the guide beams and in rolling match with the guide rods, or are rotatablely assembled on the guide rods and in rolling match with the guide beams. According to the suspended beam type hanger component and the crane disclosed by the invention, the matched sections between the guide rods and the guide beams are prolonged by adjusting the separation distance between upper and lower guide wheels, so that the swaying of the guide rods can be effectively restricted, the moving of the guide rods is more stable, and then a hanger is prevented from swaying during lifting and the positioning accuracy is improved.

Description

technical field [0001] The invention relates to a beam-type suspension assembly and a crane using the suspension assembly, belonging to the technical field of hoisting machinery. Background technique [0002] With the rapid development of modern industry, the hoisting accuracy and work efficiency of the crane are required to be higher and higher, which requires the spreader to have a smaller swing range during the hoisting process. The notification number is CN202953728U, and the Chinese utility model patent titled "crane mechanical anti-sway device" discloses a kind of anti-sway device, which includes two guide rods symmetrically arranged on the spreader and extending in the up and down direction, and the crane trolley frame There are guide holes corresponding to the two guide rods respectively, and the two guide rods are respectively guided and moved to be assembled in the corresponding guide holes. When the device is used for hoisting, since the guide hole guides the gui...

Problems solved by technology

However, there is sliding friction between the guide rod and the guide hole, and the guide rod and the guide hole are easy to wear, which affects the anti-swing effect; in addition, because the guide hole in this structure limits the length of the sliding fit section between the guide rod and the guide hole , the short sliding fit section makes the guide rod easily deformed and stuck when moving up and down, thus affecting the normal lifting of the spreader
