Description

A color steel plate portable spreader

technical field

The utility model relates to a portable hanger for color steel plates.

Background technique

When the steel plate is lifted and unloaded, a spreader is needed. At present, the cranes are all single-hook hoisted, and the second steel plate is long. When lifting, it is easy to generate internal pressure along the length of the steel plate and cause an unstable state, unable to maintain balance. In order to maintain the balance, the ordinary spreader often hangs in the middle position when it is used, which is easy to cause stress concentration and damage the plate.

Contents of the invention

The technical problem to be solved by the utility model is to provide a convenient hanging of color steel plate which realizes the even distribution of force and avoids stress concentration.

The technical solution adopted by the utility model to solve the technical problem is: to construct a portable spreader of color steel plate, including main girder, steel wire rope, two crossbars and at least two scissor lever mechanisms, the main girder and connected by wire ropes, the top of the scissor lever mechanism is connected to the main beam, and the two fulcrums at the bottom of the scissor lever mechanism are respectively fixedly connected to two crossbars, and the two crossbars are arranged oppositely. It is used to place the color steel plate to be hoisted.

In the above solution, the scissor lever mechanism includes a first short rod, a second short rod, a first long rod and a second long rod, the first short rod and the second short rod are hinged, and the first short rod The rod is hinged with the first long rod, the second short rod is hinged with the second long rod, the middle part of the first long rod is hinged with the second long rod, and the hinge point of the first short rod and the second short rod Connected with the main beam, the ends of the first long rod and the second long rod are connected with the cross bar.

In the above solution, the main beam is provided with a suspension ring connected with the scissor lever mechanism.

In the above solution, the cross bar includes an angle steel and an end plate, and the end plate is welded to both ends of the angle steel.

The portable spreader of color steel plate implementing the utility model has the following beneficial effects:

1. It can realize the average distribution of force, avoid stress concentration, and damage the steel plate surface. The scissors lever principle and angle steel are used to clamp the steel plate to increase safety and stability. The components of the spreader are simple, easy to install and disassemble, and can be reused.

2. There is no need to weld the lug plate of the lifting point before hoisting the steel plate, and it is not necessary to cut or polish the lug plate of the lifting point after the hoisting is in place, and there is no need for touch-up paint treatment, which reduces the source of danger of working at heights.

3. The scissors lever principle is used to adjust the width, which increases the flexibility and stability of the spreader hoisting and avoids the complexity of setting the width by manual operation.

4. Using the two lifting points on the flat steel main girder, the internal stress of the steel wire rope on the spreader itself in the length direction is resolved to avoid damage to the steel plate; the force component is made of angle steel, which fits perfectly with the edge of the steel plate, making Uniform force, eliminate stress concentration, reduce damage to the steel plate, increase stability and safety

5. Using this hoisting method saves labor and time, reduces costs, is safe and reliable, speeds up construction progress, creates good economic and social benefits, and has certain promotional value.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

As shown in Figures 1-3, the utility model color steel plate portable spreader includes a main girder 1, a steel wire rope 2, two crossbars 4 and at least two scissor lever mechanisms 3.

The main girder 1 is designed as 8mm flat steel, and there are two ring openings symmetrically designed to connect the upper rings 5, and then the two upper rings 5 are connected with the steel wire rope 2 respectively. The top of the scissor lever mechanism 3 is connected to the main beam 1, and the two fulcrums at the bottom of the scissor lever mechanism 3 are fixedly connected to the two crossbars 4 respectively, and the two crossbars 4 are arranged oppositely for placing the Hoisted color steel plate.

The scissor lever mechanism 3 comprises a first short rod 301, a second short rod 302, a first long rod 303 and a second long rod 304, the first short rod 301 and the second short rod 302 are hinged, and the first short rod 301 and the second short rod 302 are hinged. The first long rod 303 is hinged, the second short rod 302 and the second long rod 304 are hinged, and the middle part of the first long rod 303 and the second long rod 304 is hinged. In this example, movable bolts 305 are used for hinged connection. The hinge points of the first short rod 301 and the second short rod 302 are connected with the main beam 1 , and the ends of the first long rod 303 and the second long rod 304 are connected with the transom rod 4 .

The length of the force arm of the scissor-type lever mechanism 3 is determined according to the width of the color steel plate, and the opening of the lifting ring is set on the top to connect the lower lifting ring 6. The lower lifting ring 6 is connected to the main beam 1 by welding, and the joint between the angle steel and the angle steel is connected by a movable bolt 305. The angle can be adjusted freely. The ends of the first long rod 303 and the second long rod 304 are provided with a connecting plate 306 for connecting the cross bar 4 at the bottom of the spreader, and are connected by welding.

The cross bar 4 includes an angle steel 401 and an end plate 402, and the end plate 402 is welded to both ends of the angle steel 401 to prevent the colored steel plate from slipping off in case of accident.

The hoisting process of the present utility model is as follows:

1. After connecting the three parts of the sling, lift the wire rope 2 at the top of the sling with the hook of the crane.

2. Place the color steel plate to be hoisted on a flat surface, and use the scissor lever mechanism 3 to adjust the opening angle of the spreader, so that the bottom cross bar 4 of the spreader catches the two long sides of the color steel plate.

3. Lift the steel wire rope 2 by a crane. When lifting, the steel wire rope 2 can be automatically adjusted due to gravity, so that the hook tension acts on the middle position. Also because of the principle of the scissor lever, the bottom cross bar 4 firmly clamps the steel plate, and uses its own Structural system adds stability.

4. Just adjust the angle of the scissor lever mechanism 3 when hanging, and the suspended steel plate can be taken out.

Embodiments of the present utility model have been described above in conjunction with the accompanying drawings, but the present utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative, rather than restrictive. Under the enlightenment of the utility model, personnel can also make many forms without departing from the scope of protection of the purpose of the utility model and claims, and these all belong to the protection of the utility model.
