DETAILED DESCRIPTION

[0016] Reference is made to Figures 1-4As shown, the technical solution adopted in this specific embodiment is as follows: It includes a bottom support platform 6, two climbing support rods 4 are welded to the middle of the upper end of the bottom support platform 6, an inspection platform 2 is welded to the other end of the two climbing support rods 4, and a diagonal support rod 3 is welded between the inspection platform 2 and the bottom support platform 6. A climbing crossbar 5 is welded between the two climbing support rods 4, and a side guardrail 1 is welded between the climbing support rods 4 and the side of the upper end of the inspection platform 2. The climbing crossbar 5 includes a crossbar body 51, and an anti-slip surface layer 52 is laid on the crossbar body 51.

[0017] More specifically, several crane hooks 7 are welded onto the bottom support platform 6 to facilitate crane transportation.

[0018] More specifically, the top of the crossbar body 51 has several surface layer slots 54, and the bottom of the anti-slip surface layer 52 has several surface layer inserts 53, which are inserted into the surface layer slots 54. The anti-slip surface layer 52 is inserted into the surface layer slots 54 through the surface layer inserts 53, so that the anti-slip surface layer 52 can be better installed and laid on the crossbar body 51, preventing the anti-slip surface layer 52 from sliding, and making it convenient for workers to replace the anti-slip surface layer 52.

[0019] More specifically, the anti-slip surface layer 52 includes a fiber base layer 52-1, a rubber surface layer 52-2 bonded on top of the fiber base layer 52-1, and anti-slip protrusions 52-3 protruding outward from the top of the rubber surface layer 52-2. A surface layer insert 53 is installed at the bottom of the fiber base layer 52-1. The fiber base layer 52-1 increases the toughness of the anti-slip surface layer 52, while the rubber surface layer 52-2 and the anti-slip protrusions 52-3 enhance the anti-slip effect of the anti-slip surface layer 52.

[0020] The working principle of this utility model is as follows: When the movable fume hood is leaking and needs repair, the staff should first level the furnace. Then, the repair workers will use a crane to lift the repair device to the repair position. When moving it, the crane can be connected to the crane by hook ring 7. The repair personnel can then climb to the repair platform 2 via the climbing support rod 4 and the climbing crossbar 5, which makes it easier for the staff to weld and repair the leaks under the movable fume hood. This can effectively shorten the repair time and greatly improve the safety performance. The anti-slip surface layer 52 set on the crossbar body 51 can increase the anti-slip performance of the climbing crossbar 5. After a period of use, the staff should replace the anti-slip surface layer 52 to ensure its anti-slip performance.

[0021] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
