Description

Multifunctional lifting device for extra-large span vertical turning steel truss Technical Field The utility model relates to the technical field of steel truss lifting devices, in particular to a multifunctional lifting device for an oversized vertical turning steel truss. Background It is well known that in the construction process of an oversized vertical turning steel truss, lifting operation is a key link. When the extra-large span vertical turning steel truss is lifted, the angle of the clamping device needs to be accurately adjusted according to specific working environments and truss structures. The traditional method relies on manual adjustment, and the method is low in efficiency and difficult to ensure that the optimal clamping angle can be achieved every time. Errors in the manual adjustment process may result in a loose or misaligned grip, increasing construction risks. In order to maintain stability of the clamping mechanism in the desired position, a reliable locking mechanism is required. The traditional locking mode is usually realized by a simple locking function of a driving motor. However, this method does not perform well in the face of large operating pressures, and is prone to damage to mechanical components. The long-term use of the simple locking function may also affect the service life of the drive motor itself, since it is not designed to withstand high pressures for a long period of time. For the reasons mentioned above, operators face a certain safety risk in performing these tasks. For example, if the clamping angle is manually adjusted, unexpected movement or unstable fixation may cause equipment to be out of control, resulting in personnel injury or property loss, and the manual adjustment and easy locking mechanism limit the overall working efficiency. Each adjustment takes a lot of time and frequent manual interventions reduce the progress of the whole project, so that a solution to this technical problem is necessary.
