Three-fork connecting rod self-adjusting coil spreader

Abstract

The invention discloses a three-fork connecting rod self-adjusting type coil hoist. Hanging lugs are arranged on the hanging pan, and the hanging lugs are connected to the lifting chain through a D-shaped buckle. The center of the hanging pan is fixed with a guide sleeve; the ring wire The screw body of the rod passes through the guide sleeve and is sequentially set with a movable limit sleeve, an adjusting nut, a three-fork joint arm sleeve and a safety nut. The outer circumference of the three-fork joint arm sleeve is fixed with a connecting lug, and the connecting lug is connected to the movable joint through the bolt. Arm connection; the support arm is fixed under the hanging pan, the support arm is fixed with the first fixed arm, the first fixed arm is connected to one end of the boom through bolts, the other end of the boom is provided with a side hook, and the middle section of the boom The position is fixed with a second fixed arm, and the second fixed arm is connected with the movable arm through bolts. The invention has a simple structure, is easy to manufacture and is easy to operate. Lifting operators can operate remotely and quickly complete the lifting operation, effectively improving work efficiency and safety factor, improving the working environment and reducing labor intensity.

Description

technical field

[0001] The invention relates to a sling for hoisting a coiled product with internal voids, in particular to a self-adjusting coiled sling with a three-fork link. Background technique

[0002] With the development of modern economy and technology, large single heavy coils are gradually replacing straight round steel and widely used in transportation, equipment manufacturing, electronics industry, hardware and home appliances, light steel structure, construction and other industries. In order to reduce the development requirements of energy consumption, high-strength steel is gradually replacing medium-strength steel. Most high-strength steels require heat treatment (eg: spheroidizing annealing, stress relief annealing, etc.) before cold working (eg: drawing, upsetting, turning, etc.). At present, domestic coil heat treatment generally adopts well furnace , due to the special structure of the pit furnace, the weight of the coil (generally ≥ 2 tons / reel), and t...

Examples

Embodiment

[0014] Example: A preferred embodiment of the present invention is as follows, the self-adjusting coil spreader of the tripod link, such as figure 1 , figure 2 and image 3 , the hanging lugs 3 are symmetrically welded on the top of the hanging plate 7, the lifting chain 2 is connected to the hanging lugs 3 through two sets of D-shaped shackles 4, and the first fixed connection arm 8 on the hanging plate 7 and the support arm 5 is formed. On the balance structure, the three suspension arms 11 are connected by bolts 13, and the circular screw rod 1 passes through the guide tube 6 on the hanging plate 7 at the center position of the balance structure. like Figure 4 , the screw body of the ring screw 1 is equipped with a movable limit sleeve 9 and a trident connecting arm sleeve 15. The trident connecting arm sleeve 15 is composed of three connecting lugs 15a uniformly welded on the outside of the sleeve 15b. The movable limit sleeve 9 Two adjusting nuts 10 are installed w...
