Description

Heavy prefabricated section anchor clamps

Technical Field

The utility model relates to a construction tool field specifically is a heavy prefabricated section anchor clamps.

Background

With the development of society, in the building field, people increasingly like to use larger bricks or prefabricated blocks to build buildings, because the bricks are larger and heavier, one worker cannot clamp the bricks to carry away by using a common brick clamp, if two people directly carry or lift the bricks, the long-time waist bending and rising operation are easy to fatigue, the efficiency is low, and the serious influence is also caused on the human health; meanwhile, the construction site has complex environment and inconvenient traffic, and accidents are very easy to happen, so that constructors are sprained or bricks are crushed.

In order to avoid the above problems, a new manual clamp has been developed, which can minimize the above problems and bring greater convenience to the work of people, and is a technical problem to be solved.

Therefore, how to design a heavy precast block clamp becomes a problem to be solved currently.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a heavy prefabricated section anchor clamps, precast concrete piece that transports that can convenient and fast.

In order to solve the problems, the utility model adopts the following technical proposal,

a heavy precast block clamp comprises two clamping rod assemblies and a rotating shaft, wherein the middle parts of the two clamping rod assemblies are hinged together; the clamping rod assembly comprises a clamp head, a short upright post fixedly connected with the upper part of the clamp head, a hinged rod with one end fixedly connected with the short upright post, and a handle fixedly connected with the other end of the hinged rod; the middle lower part of the hinge rod is rotationally connected with the rotating shaft; the clamp head is provided with a force application surface a, and the force application surface a is vertical to the length direction of the handle; and when viewed from the direction parallel to the force application surface a, the distance between the force application surface a of the clamp head and the rotating shaft is b, the distance between the rotating shaft and the end part of the handle is c, and the distance c is greater than the distance b.

Furthermore, a rubber plate is arranged on one surface clamped by the clamp head.

Further, the rubber plate is provided with a groove.

Further, the handle is provided with a handle sleeve.

The utility model has the advantages that:

1. the handle sleeve designed on the handle can prevent hands from sweating and slipping, so that the safety is higher;

2. the rubber plate arranged on the clamp head can prevent the precast block from being in hard contact with the clamp head, so that the precast block is easy to damage and waste products are caused;

3. the contact area between the precast block and the clamp head can be increased through the grooves formed in the rubber plate, so that the clamping is more stable;

4. through the hinging of the two clamping rod assemblies, the large precast block can be easily lifted by two people by utilizing the lever principle, so that the condition that the work injury is caused by the half-way falling force due to the fact that one person carries the precast block too heavy is avoided, and the work injury caused by the fact that the individual precast block is broken when the quality is poor due to the use of a clamp is also avoided;

5. the device has the advantages of simple structure, strong practicability, easy popularization and suitability for the current complex and changeable construction site.
