Specifically, reinforcing plates 4 fixedly connected with the channel steel 2 are further arranged between the channel steel 2, and the reinforcing plates 4 are positioned among the plurality of vertical plates 3 to play a role in reinforcing the strength of the supporting beam 1. The bearing beam 7 is arranged below the supporting beam 1 and is assembled and connected with the supporting beam 1, and specifically, the bearing beam 7 is a box-type beam. Specifically, the bearing beam 7 is slidably connected with the supporting beam 1, and the bearing beam 7 can move telescopically relative to the supporting beam 1. As shown in fig. 2, a first driving end support 8, a second driving end support 12 and a plurality of free end supports 9 are arranged at the top of the bearing beam 7, specifically, in a state that the bearing beam 7 is fully extended relative to the supporting beam 1, the first driving end support 8 and the second driving end support 12 are welded at the top of one end of the bearing beam 7, which is close to the supporting beam 1, and the first driving end support 8 and the second driving end support 12 are respectively fixedly connected with two ends of a driving chain, so that the telescopic movement of the bearing beam 7 relative to the supporting beam 1 is realized under the driving of the driving chain. The guide wheels 10 are arranged on the first driving end support 8, the second driving end support 12 and the free end support 9, the diameter of each guide wheel 10 is matched with the height of the inner groove of the channel steel 2, and each guide wheel 10 is arranged on the connecting shafts of the first driving end support 8, the second driving end support 12 and the free end support 9 and can roll in the channel steel 2 of the supporting beam 1. When the bearing beam 7 does not extend out of the supporting beam 1, the guide wheel 10 of the free end support 9 is in contact with the channel steel 2, so that a supporting effect is achieved; when the carrier beam 7 extends out of the support beam 1, the free end support 9 is suspended, and the carrier beam 7 is connected with the support beam 1 by means of the first driving end support 8, the second driving end support 12 and the guide wheels.
