Description

Freight Tongs {Tongs for heavy weight traction}

The present invention relates to a cargo belt clamp for easily loading a cargo protection belt, which is one of the devices that prevents damage to cargo when the ropes of a cargo loading box are tied, to a loading box on the ground.

In general, when transporting cargo, the cargo is tightly bound using a rope after loading the cargo in the cargo box of the cargo truck.This is because if the binding of the loaded cargo is neglected, the cargo may fall from the cargo box while driving. This is because there is a risk of causing an accident of a follow-up vehicle by the cargo that has fallen into the vehicle, and damage due to damage or loss of the cargo may occur.

However, if the cargo is tightly tied to prevent the cargo from falling, there is a concern that the loaded cargo may be damaged or damaged by the rope. In the past, buffers such as newspapers, boxes, clothes, etc. were placed on the top of the loaded cargo. I even tied a rope over it to the corner,

A so-called cargo protection belt has been developed and used to prevent damage to cargo when the rope is bound.

This cargo protection belt consists of a configuration in which a pair of flat-shaped sub-body is connected by mutual members, and one of the pair of sub-body is placed on a horizontal plane among the upper corners of the cargo and the other is installed in close contact with the vertical plane. It acts to safely protect the cargo from the ropes passing over it.

These cargo clamps are similar to the structure of the heavy clamping device.

A general heavy object clamping device is used to grasp both sides of a heavy object such as a curb or block and transport it to a designated location.

However, the conventional heavy object clamping device has a structural problem in that the heavy object cannot be easily separated because the clamp continues to maintain the gripping state when placing the heavy object on the floor after transporting it due to compression in the process of grasping and lifting the heavy object. .

In particular, since the operator must open or push the clamp to both sides to release the gripping state, the working time increases and safety accidents occur.

In addition, since the clamp must be kept open to the outside in order to grip heavy objects, there is a problem of lowering work efficiency.

In order to stably install the conventional cargo protection belt on the upper edge of the loaded cargo, the operator had to install the cargo protection belt on the upper edge of the cargo while the worker was directly rising above the loaded cargo. Not only is this cumbersome and inconvenient point, but above all, there is a very high risk of an accident in which an operator who climbed over the loaded cargo falls to the ground during the installation process, and in fact, there is a problem that often occurs.

Although there may be differences depending on the vehicle type of the truck or the type of cargo, in general, the height of the loaded cargo can reach 4 to 5m from the ground. At this height, if an operator falls to the ground during the installation work of the cargo protection belt, There is a risk of serious injuries and in severe cases that may lead to obstacles or loss of life, prolonged working hours, such as separating heavy objects by spreading them outward, or causing safety accidents, and the resulting work efficiency. The problem that the operator cannot easily use due to the complexity of the reduction and structure is a problem to be solved by the present invention.

In order to solve the above problems, the present invention is an outer rod 4 provided with an operation part connected by a handle spring 22 between the fixed handle 1 and the moving handle 2, and the outer rod 4 One side is inserted into and the other side is an inner rod (5) inclined to the inside of 120 degrees, a rack gear fixing portion (18) in which the end of the inner rod (5) is inserted and fixed to the outer rod (4), and the A wire 17 connected to one end of the movable handle (2) and a rack-lock wire penetrating part (not shown) of the rack gear fixing part 18, and a steel wire fixing part 19 and a rack installed in front of the operation part. A steel wire 16 connected and installed through the steel wire insertion hole 18-2 of the gear fixing part 18, the rack gear fixing part 18, the rack gear fixing part 18, and the steel wire in the direction of the handle (16) It is installed outside the connection portion of the spring 21 installed between the inner rod 5 and the inner rod 5 inserted into the outer rod 4, and a ring shape to securely fix the inner and outer rods 5 and 4 It is composed of female and male screws of the two connection fixing parts (3-1, 3-2) that are screwed together, the rack gear fixing part (18) inserted into the inner rod (5), and the rack gear high. The solution of the present invention is to provide a clamp consisting of a rack gear 15 inserted into the top 18 and a clamp part connected to the end of the rack gear 15 and installed outside the end of the inner rod 5 It is a means.

The present invention shortens the working time, such as separating the heavy object after the operator grabs or picks up, moves and separates it by operating the tongs with a simple hand motion when a heavy object is placed on the floor, reduces safety accidents, and improves work efficiency. It is a critical period and has a simple structure, which makes it easy for workers to use.
