Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The following description is combined with the attached drawings 1-5, the horizontal annular welding construction platform for the bin cylinder provided by the utility model comprises a hanging basket and an operation platform 9 arranged in the hanging basket, wherein a rear surrounding frame 1 of the hanging basket is a ladder stand, lifting lugs 3 are arranged at the top parts of a left surrounding frame 2 and a right surrounding frame 2 of the hanging basket, a left cantilever beam and a right cantilever beam (hereinafter collectively referred to as cantilever beams) extending forwards are arranged at the upper part of the hanging basket, and a walking wheel component 5 is arranged at the outer end of each cantilever beam 4; the walking wheel assembly 5 comprises a connecting frame 51 fixedly connected with the cantilever beam 4, two walking wheels 52 are arranged in the connecting frame 51, and the walking wheels 52 are arranged on the upper edge of the bin steel plate 10; at least one walking wheel assembly 5 is provided with a power assembly 6, the power assembly 6 comprises a driven gear 61 and a driving gear 62, wherein the driven gear 61 is fixedly connected to one side of the walking wheel, and the driving gear 62 is arranged between the two driven gears 61 and is meshed with the driven gears 61; the other end of the shaft lever of the driving gear 62 is fixedly connected with a chain wheel 64, and a chain 63 is arranged on the chain wheel 64.
Based on the principle that the larger the moment, the smaller the force, the diameter of the sprocket 64 is equal to or larger than the sum of the diameters of the driven gear 61 and the driving gear 62. The chain wheel 64 is rotated by pulling the chain 63, so as to drive the driven gear 61 and the travelling wheel 52 to rotate, and the operation platform moves on the bin. The chain 63 may be pulled manually or by any known means. For example, the lower end of the chain 63 is mounted on a power sprocket, and the power sprocket is connected with a motor and a speed reducer.
