SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a elevating gear based on electric hoist to solve above-mentioned problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a lifting device based on an electric hoist comprises a portal frame, the electric hoist and a drag chain mechanism; the electric hoist is arranged on the portal frame and is connected with a power supply through a power line, and the power line is arranged in the drag chain mechanism;
the drag chain mechanism comprises a first drag chain and a second drag chain; one end of the first support chain is connected with the electric hoist, and the other end of the first support chain is connected with the portal frame; one end of the second drag chain is connected with a power supply, and the other end of the second drag chain is connected with the portal frame; the power cord is connected to the electric hoist through the first tow chain and the second tow chain in turn from the power source.
Furthermore, the portal frame comprises telescopic support legs and a cross beam, the two telescopic support legs are vertically arranged, and the tops of the two telescopic support legs cross the fixedly arranged cross beam; the electric hoist is arranged on the cross beam and can slide along the cross beam.
Furthermore, one end of the first drag chain is connected with the electric hoist, and the other end of the first drag chain is connected with the end part of the beam; the second drag chain is arranged along one telescopic supporting leg, and the first drag chain and the second drag chain are mutually vertical in space.
Furthermore, a power box is fixedly arranged on the telescopic supporting leg, and a power line is connected to the power box.
Compared with the prior art, the utility model discloses there is following technological effect:
the utility model discloses a set up tow chain mechanism, two sections tow chains carry out comprehensive protection and arrangement to the power cord of going out from the power supply box, and the tow chain itself has good support, has fine protection to its inside power cord, in the electric hoist working process, prevents effectively that the power cord from wearing and tearing and knoing, stops the potential safety hazard.
The portal frame is of a telescopic structure, and in the telescopic process, the towline on the side can be well protected by the towline on the side.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
referring to fig. 1, a lifting device based on an electric hoist comprises a portal frame 1, an electric hoist 6 and a drag chain mechanism; the electric hoist 6 is arranged on the portal frame 1, the electric hoist is connected with a power supply through a power line, and the power line is arranged in the drag chain mechanism;
the drag chain mechanism comprises a first drag chain 3 and a second drag chain 4; one end of the first support chain is connected with the electric hoist, and the other end of the first support chain is connected with the portal frame 1; one end of the second drag chain 4 is connected with a power supply, and the other end is connected with the portal frame 1; the power cord is connected to the electric hoist 6 from the power source through the first tow chain 3 and the second tow chain 4 in sequence.
