Description

Lifting appliance for bottom of outer circle

Technical Field

The utility model relates to a hoist field especially relates to an excircle bottom hoist.

Background

A lifting appliance refers to a device for lifting a heavy object in a lifting machine. The most common lifting devices for lifting finished articles are lifting hooks, lifting straps, lifting rings, lifting suction cups, clamps, forks and the like. Is widely applied to the hoisting industry. Traditional hoist adopts the clamp formula of getting or inserts the formula of getting to connect more, but when using traditional hoist to hoist for circular or nearly circular shape product in cross-section, both had the inconvenient problem of connection, owing to with product outward appearance direct contact, cause wearing and tearing easily to the product surface again, influence product quality.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a convenient to use and can not cause the excircle bottom hoist of wearing and tearing to the product surface.

The utility model discloses a realize through following technical scheme:

the utility model provides an excircle bottom hoist which characterized in that includes: a suspender, a plurality of claws hinged with the upper end of the suspender and a sliding sleeve sleeved on the suspender and sliding along the suspender,

the jack catch is the L type, and the jack catch lower extreme rigid coupling has inward brace table, be equipped with the connecting rod between sliding sleeve and the jack catch, the both ends of connecting rod are articulated with sliding sleeve and jack catch middle part respectively, and threaded connection has the locking screw who passes the sliding sleeve lateral wall on the sliding sleeve.

Preferably, the lower end of the suspender is fixedly connected with a limiting block.

Preferably, the upper end of the hanging rod is fixedly connected with a hanging ring.

The utility model has the advantages that:

when the sliding sleeve slides on the hanging rod, the clamping jaws are driven to open or contract through the connecting rods, the distance between every two adjacent clamping jaws is changed, the clamping jaws cover the outside of a product during use, the supporting table is inserted into the bottom of the product, the hanging rod is pulled upwards, the product is clamped by the clamping jaws, the sliding sleeve is locked by screwing the locking screw, and the product can be hoisted.

Drawings

Fig. 1 is a schematic view of the structure of the present invention.

Fig. 2 is a schematic perspective view of the present invention.

Fig. 3 is a schematic top view of the present invention.

In the figure: 1. the lifting rod comprises a lifting rod body, 2 clamping jaws, 3 sliding sleeves, 4 supporting tables, 5 connecting rods, 6 locking screws, 7 limiting blocks and 8 lifting rings.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a: a suspender 11, a plurality of claws 2 which surround the suspender and are hinged with the upper end of the suspender, and a sliding sleeve 3 which is sleeved on the suspender and slides along the suspender,

the clamping jaw is L-shaped, a supporting platform 4 extending inwards is fixedly connected at the lower end of the clamping jaw, a connecting rod 5 is arranged between the sliding sleeve and the clamping jaw, two ends of the connecting rod are respectively hinged with the sliding sleeve and the middle part of the clamping jaw, when the sliding sleeve moves upwards, the distance between the sheath and the upper end of the clamping jaw is shortened, because the length of the connecting rod is fixed, the included angle between the clamping jaw and the suspender is reduced, the clamping jaw contracts inwards, when the clamping jaw moves downwards, the direction is opposite, a locking screw rod 6 penetrating through the side wall of the sliding sleeve is connected on the sliding sleeve in a threaded manner, the sliding sleeve and the suspender can be locked and fixed by the locking screw rod, the sliding sleeve is prevented from moving upwards and downwards, when the lifting appliance in the embodiment is used, the clamping jaw is firstly opened, the sliding sleeve is positioned at the lower end of the suspender, the sliding sleeve is, promote the sliding sleeve through the connecting rod along jib upward movement, contained angle diminishes between jack catch and the jib, the brace table inserts the product bottom, when the brace table of all jack catch lower extremes all inserted the product bottom, continue upwards to stimulate the jib, can hoist the product, because the effect of product gravity can make the jack catch press from both sides tightly with the product throughout, form the auto-lock, convenient to use is swift, for the stability after improving the hoist, can also screw up locking screw, avoids the product to drop from the brace table.

Preferably, the lower end of the suspender is fixedly connected with a limiting block 7, and the limiting block can adjust the sliding range of the sliding sleeve on the suspender, namely, the maximum opening amount of the clamping jaw is adjusted.

Preferably, the upper end of the suspender is fixedly connected with a suspension ring 8, and the lifting appliance in the embodiment can be connected with a driving device such as a crane and a crown block.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Claims (3)
