Description

A self-mounted four-claw quenching spreader

technical field

The utility model relates to a self-mounted four-claw quenching hanger, in particular to a quenching hoisting tool.

Background technique

Existing quenching slings mostly use iron chains and hooks, and most of them are three claws. When using iron chains to hoist quenched workpieces, due to the narrow hook surface and iron chains, the outer surface of the workpiece is often strangled, which affects the surface quality of the workpiece; in addition, the traditional iron chain hoist requires at least 3 people to cooperate with the placement of the hoist. hook, both time-consuming and laborious.

Utility model content

The purpose of the utility model is to provide a self-mounted four-claw quenching sling with simple structure, easy operation during use, self-mounting, and a certain adjustment range; the self-mounting four-claw quenching sling, It includes a cross beam, four strong rings and four hanging arms, a strong ring is vertically arranged above each beam of the cross beam, and a hanging arm is vertically arranged under each beam of the cross beam.

The hanging arm includes a hanging arm main body, a hook plate, a rotating shaft and a nut, and the vertical bottom end of the hanging arm main body is connected to the hook plate through the rotating shaft II and the nut II.

Several limit holes are drilled on the cross beam for the bolts of the shackle to pass through.

The strong ring is connected with the cross beam through a shackle and a limit hole.

The hanging arm is connected to the cross beam through the rotating shaft I, the nut I, and the limit hole, and the distance between the hanging arms is adjusted through the limit hole to realize the adjustment of the hanging range and the hoisting of the square plate and the ring piece.

The distance between the limit hole fixed by the hanging arm and the center of the cross beam is greater than the distance between the shackle used to connect the strong ring and the center of the cross beam.

The hook plate in the hanging arm can be pushed into the main body of the hanging arm by the workpiece when it is in contact with the workpiece during hoisting. When it reaches the bottom of the workpiece, it can be released by the principle of gravity to realize self-hanging, saving time and effort. In addition, the contact area between the hook plate and the workpiece is large when the hook plate is working, and the main body of the hanging arm and the workpiece are perpendicular to each other, which can ensure the surface quality of the workpiece; the four-claw spreader, the four booms are all limited, compared with the chain-type three-claw spreader During the quenching process, the lifting workpiece is more stable, as long as it is within the rated load range, the workpiece will not fall off, and the safety is higher.

Advantages of the utility model:

The utility model is simple in structure, low in cost, safe and reliable, stable in performance, convenient to use, and has outstanding features such as large adjustable range, many types of workpieces that can be hoisted, self-mounting, surface quality of workpieces can be guaranteed, and safety factor is large;

detailed description

Example

As shown in FIG. 1 , the self-mounting four-claw quenching spreader includes a cross beam 1 , four hanging arms 2 , four strong rings 3 , and a shackle 4 . A strong ring 3 is vertically arranged above each beam of the cross beam 1 , and a hanging arm 2 is vertically arranged below each beam of the cross beam 1 . The strong ring 3 is connected to the shackle 4, and is finally connected to the crown block with an iron chain; the shackle 4 is connected to the cross beam 1, which is convenient for installation and adjustment, and is also safe and reliable; a certain number of limit holes are drilled on the cross beam 1 , the hanging arm 2 is connected with the rotating shaft I5 and the nut I6 through the limit hole 12 and the cross beam 1. According to the size of the workpiece to be hoisted, the hanging arm 2 can be adjusted through the limit hole to realize the adjustment of the hoisting range. In addition, the limit The positioning hole 12 defines the position of the hanging arm 2, so that it cannot swing left and right, and ensures that the hanging arm 2 is perpendicular to the workpiece. The distance between the shackle 4 of the 3 and the center of the cross beam 1.

As shown in FIG. 2 , the hanging arm 2 is composed of a hanging arm main body 7 , a hook plate 8 , a rotating shaft II 9 and a nut II 10 . Hook plate 8 is just positioned at the position as shown in Figure 2 when unloaded due to gravity. Figure 3 is a schematic diagram of the self-hanging of the hook plate. When the hanging arm 2 moves downward, the workpiece 11 contacts the hook plate 8 and pushes the hook plate 8 until it is received in the main body 7 of the hanging arm; when the workpiece 11 and the hook plate 8 When no longer in contact, the hook plate 8 is released voluntarily due to the effect of gravity, and finally realizes automatic mounting.

The self-mounting four-claw quenching spreader can realize the automatic mounting operation of the workpiece, saving a lot of labor costs, fast and stable mounting, strong bearing capacity, safe and reliable, convenient to use, and has obvious advantages.
