Description

A kind of scaffolding steel pipe automatic delivery straightening device

technical field

The utility model relates to steel pipes for construction, in particular to an automatic delivery and straightening device for scaffold steel pipes.

Background technique

Scaffolding is widely used in today's construction sites. When the construction personnel work on the scaffolding, the scaffolding is used as a force-bearing component, which is easy to cause deformation of some steel pipes. It is also easy to cause deformation of the steel pipes during the process of removing the scaffolding. According to the traditional method, manual hammering is used. Straightening is laborious and time-consuming, and at the same time, the construction quality cannot be guaranteed, and it is easy to cause secondary damage to the steel pipe; the large-scale steel pipe straightening machines currently on the market are expensive, occupy a large area, and require high technical level of workers. There are great limitations in practical engineering use.

The existing small scaffolding steel pipe straightening device has the following shortcomings: (1) When the steel pipe is straightened, the steel pipe cannot move horizontally or rotate easily in the device, and the steel pipe must be pulled out from the device and then reinserted in the device when it is straightened. The other part of the device is straightened, and the work efficiency is low; (2) the straightening part of the device is made of steel pipe fasteners, which has low rigidity and strength, and the frame body of the straightening part is easily deformed during use, and the device needs to be maintained or adjusted in time. (3) During the straightening process, because the two ends of the steel pipe are not fixed, it is easy to rotate the steel pipe during the straightening process, resulting in poor straightening effect.

Secondly, due to the large net weight and long length of the scaffolding steel pipe itself, the straightening process is troublesome, and the labor intensity of the operator is greatly increased during batch straightening. In the existing steel pipe delivery device, the bundles of steel pipes are placed on the feeding rack, decomposed and laid flat, and slowly fall through the gradient of the feeding rack and the weight of the steel pipe itself, which often causes multiple steel pipes to be loaded at one time, resulting in multiple steel pipes. Crowded together, inefficient. After straightening the steel pipe, it needs to be removed manually, which is time-consuming and labor-intensive.

At present, there is a lack of a device in the domestic market that is suitable for general engineering and can easily and conveniently perform automatic delivery and straightening of scaffolding steel pipes, especially for the situation where the degree of bending of the steel pipes is not large and the technical level of the construction team is not too high, there is a lack of a convenient and efficient device. The scaffolding steel pipe automatic delivery straightening device.
