Description

Anti-slip and side-turning stiffening ring lifting device

Technical Field

The utility model belongs to the technical field of construction slings, and particularly relates to a stiffening ring sling device capable of preventing slipping and rollover.

Background

In the manufacturing process of the water delivery steel pipe, the assembly welding work of the stiffening ring is a key process in the process, and the stiffening ring is installed in the past in a manual carrying or steel wire rope sleeve hoisting mode, so that the installation mode is high in labor intensity, the steel wire rope is easy to damage, the cost is not saved, and potential safety hazards exist in the process. Therefore, a lifting device capable of preventing rollover and slippage in the lifting process of the stiffening ring and guaranteeing construction safety and engineering progress is needed.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art, and aims to provide a lifting device capable of preventing rollover and slippage in the lifting process of a stiffening ring and ensuring construction safety and engineering progress.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the utility model provides a slip prevention and stiffening ring hoist device of turning on one's side, includes rings and fixture block, rings are fixed to be set up at the fixture block top, be provided with horizontal open-ended U type draw-in groove on the fixture block, the equal downward sloping setting of last side slope and the lower slope of U type draw-in groove, the slope of going up the side slope is greater than the slope of lower side slope.

Further, the gradient of the upper side slope is 1:6, the gradient of the lower side slope is 1:10.

further, the aperture of the hanging ring is 10cm.

Compared with the prior art, the utility model has the following beneficial effects:

the utility model has simple processing and can be manufactured by utilizing the leftover materials for manufacturing the stiffening ring. When in hoisting, a plurality of slings are adopted to hoist the left and right side parts and the middle part of the stiffening ring, the stiffening ring is transversely inserted into the clamping groove through the U-shaped clamping groove of the clamping block, and the inner ring of the stiffening ring is clamped by the downward inclined upper side slope and lower side slope to limit, so that the stiffening ring is prevented from rollover and sliding in the lifting process.

Reference numerals:

1-hanging rings, 2-clamping blocks, 3-upper slopes, 4-lower slopes and 5-stiffening rings.

Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments.

As shown in fig. 1 and fig. 2, a stiffening ring lifting device for preventing sliding and rollover comprises a lifting ring 1 and a clamping block 2, wherein the lifting ring 1 is fixedly arranged at the top of the clamping block 2, a U-shaped clamping groove with a transverse opening is arranged on the clamping block 2, an upper slope 3 and a lower slope 4 of the U-shaped clamping groove are obliquely arranged downwards, and the gradient of the upper slope 3 is greater than that of the lower slope 4.

Wherein, the slope of the upper slope 3 is 1:6, the gradient of the lower side slope 4 is 1:10, the gradient of the upper slope 3 is larger, and the inner side of the stiffening ring 5 can be better prevented from turning on one side outwards in the hoisting process. The aperture of the hanging ring 1 is 10cm, and the hanging ring is used for connecting a steel wire rope during hanging.

In the construction process, the lifting device is respectively fixed at the left side part, the right side part and the middle part of the stiffening ring 5, and the U-shaped clamping groove of the clamping block 2 is used for allowing the stiffening ring 5 to be inserted. The upper side slope 3 and the lower side slope 4 have slopes, the self weight of the stiffening ring 5 is recycled, the outer arc section of the stiffening ring 5 can be tightly clamped, the stiffening ring 5 is prevented from sliding down due to gravity center deviation during hoisting, meanwhile, the inner side of the stiffening ring 5 is prevented from turning on one side outwards, and the safety risk in the hoisting process is ensured. Then the craftsman controls the gantry crane through the remote controller, lifts the stiffening ring 5 to the mounting position of the outer wall of the pressure steel pipe, slightly adjusts the position of the stiffening ring, loosens the steel wire rope after the lower part is supported, slowly separates the stiffening ring 5 along the upper side slope of the clamping groove, and then controls the gantry crane to return the lifting appliance to the initial position for recycling. The lifting device has the advantages of being flexible and convenient in structure, low in manufacturing cost, capable of tightly locking the stiffening ring in the lifting process, preventing safety accidents such as sideslip and sliding, improving working efficiency, saving cost and greatly accelerating construction progress.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
