In an embodiment, the power means 3 may comprise an electric hoist. The electric hoist is a special lifting equipment, is installed on overhead traveling cranes and gantry cranes, has the characteristics of small volume, light dead weight, simple operation, convenient use and the like, and is used in places such as industrial and mining enterprises, warehouses, docks and the like. By arranging the electric hoist on the support beam 2, the electric hoist can be used for providing power to lift the rigid frame beam.
It should be understood that other hoisting equipment may be selected according to the requirements of the actual application scenario in the embodiment of the present application, as long as the selected hoisting equipment can provide the power required by the lifting of the rigid frame beam, and the specific structure of the power device 3 is not limited in the embodiment of the present application.
Specifically, the power device 3 may include a group-hoisting frame electric hoist, and the rated hoisting capacity of the group-hoisting frame electric hoist is greater than or equal to 7.5 tons. The hoisting cost is high due to the fact that the rated hoisting weight of the electric hoist is too large, and the hoisting weight is not enough or the efficiency is too low due to the fact that the rated hoisting weight of the electric hoist is too small. In consideration of cost and demand, the electric hoist of the group hanging climbing frame of two types is provided, namely the electric hoist of the group hanging climbing frame of DHP5 type and DHP7.5 type, and experiments show that the lifting times of the electric hoist of the two types with the same load in the same time are compared according to the lifting demand of a conventional rigid frame beam, and the electric hoist of the group hanging climbing frame of DHP7.5 type is obviously more than that of the electric hoist of the group hanging climbing frame of DHP5 type. Therefore, the DHP7.5 type electric hoist for the group hanging and climbing frame can be selected from the viewpoint of improving the construction efficiency.
In one embodiment, a single anchor point may be provided on the frame beam, with the power unit 3 being connected to the frame beam via the anchor point. The cost of a single anchoring suspension ring is about 20 yuan, and the more the number of anchoring points arranged on the rigid frame beam is, the more the number of corresponding anchoring suspension rings is, and the higher the corresponding cost is. However, the hoisting strength may be insufficient due to the too small number of the anchoring hoisting rings, so that a single anchoring hoisting ring and two anchoring hoisting rings are respectively selected for experiments on the basis of considering both the strength and the cost; wherein, the equilibrium when single anchor rings lug weld in the gravity center point of rigid frame roof beam in order to guarantee to promote the rigid frame roof beam, two anchor rings then weld respectively at the both ends of rigid frame roof beam in order to improve the stability of promoting the rigid frame roof beam. Compared through the experiment, single anchor rings and two anchor rings can all satisfy the intensity demand of hoist and mount, consequently, on the basis of considering cost and efficiency, single anchor rings (correspond single anchor point promptly) can be selected in this application and hoist to can save the cost as far as possible, and also minimize the welding time of anchor rings, thereby improve the efficiency of construction.
In one embodiment, the electric hoist and the rigid frame beam can be connected in a positive hanging mode. The electric hoist head of the forward hanging climbing frame is connected with the upper part of the frame body, the lower lifting hook is connected with the lower part of the frame body, the lifting chain wheel rotates anticlockwise, the frame body is lifted, and each lifting layer needs to be hung on the frame body again or lifted by means of a steel wire rope. Because the upside-down hanging electric hoist does not have systematic waterproof and mud-proof measures, the motor is easy to damage when the electric hoist works in a severe environment, and the operation is stopped. Therefore, the electric hoist of the climbing frame is preferably hung in the application. It should be understood that, in the embodiment of the present application, a connection manner of the electric hoist and the rigid frame beam, for example, an inverted connection manner, may be selected according to a requirement of an actual application scenario, as long as the selected connection manner of the electric hoist and the rigid frame beam can meet a requirement for lifting the rigid frame beam, and a specific connection manner of the electric hoist and the rigid frame beam is not limited in the embodiment of the present application.
In one embodiment, the electric hoist uses a two-link chain as the hoisting rope. Since the number of the hoisting ropes is increased, the strength thereof is increased, but when the number of the hoisting ropes is increased, the cost is increased, and since the plurality of chains are piled up, the collision of the chains with the motor is caused, thereby causing a safety hazard. Consequently, the preferred two-link chain of this application can satisfy the demand that promotes intensity as the lifting rope, two chains promptly, also can avoid the incident, can also save the cost simultaneously.

For the consideration of cost and stability, since it is difficult for the single support rod 1 and the two support rods 1 to satisfy the requirement of stability, the present application considers only the four support rod 1 structure and the three support rod 1 structure. However, for the three support rod 1 structure, since the number of the preferred anchoring rings in this application is one, that is, the number of the anchoring points is one, then the rigid frame beam is in the lifting process, the stress point at the top of the support rod 1 is just one, in the long-term use process, the loss of the stress point is serious, thereby causing the damage of the whole lifting device, and the stability and flexibility of the three support rod 1 structure are slightly poor relative to the four support rod 1 structures, therefore, the four support rod 1 structure is preferred in this application. It should be understood that the number of the support rods 1 in the embodiment of the present application may be selected according to the requirements of practical application scenarios, for example, five, six, and the like, as long as the number of the selected support rods 1 can meet the requirement of the lifting of the rigid frame beam, and the specific number of the support rods 1 in the embodiment of the present application is not limited.
