The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The horizontal annular welding construction platform for the bin cylinder 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 tops 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 assembly 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. And the hanging basket can be moved more conveniently and more laborsavingly by matching the controller.

The lower part of the hanging basket is provided with a supporting rod 7, the outer end of the supporting rod 7 is provided with a horizontal directional wheel 8, and the periphery of the horizontal directional wheel 8 is in contact with the outer wall of the bin barrel. Furthermore, the horizontal orientation wheel 8 is a pulley, a pulley frame of the horizontal orientation wheel 8 is connected with a lead screw 11, and the lead screw 11 is arranged in the support rod 7. The position of the horizontal orientation wheel 8 is adjusted by the rotatable lead screw, and the upright posture of the construction hanging basket can be still kept when the outer side of the welded component inclines. The walking track of the horizontally oriented wheel in the other direction can be used as a reference for judging whether the hanging basket moves horizontally or not.

Two layers of operating platforms 9 can be arranged in the hanging basket and are respectively arranged at the bottom and the middle of the hanging basket. Under the condition of ensuring the stability of the fixing structure of the operating platform, the operating platform 9 can be designed to be detachable and fixed at the bottom of the hanging basket or any height according to construction requirements.

During operation, the construction platform is hoisted by a crane, the walking wheels are aligned with the upper edge of the bin, and the hanging basket is hung on the upper edge of the bin steel plate 10. The mobile construction platform provided by the invention is not limited to welding a circular bin, and is also suitable for linear welding of other vertical steel plates.

The hanging basket of the left chain 63 is pulled to move rightwards, and the hanging basket of the right chain is pulled to move leftwards. And pulling the chain to move the hanging basket to the welding point to perform welding. The welding propulsion is matched with the movement of the hanging basket to complete the annular welding of the barrel.

The operating personnel can enter the construction hanging basket from the crawling ladder, and after the operation is finished, the personnel can withdraw on the original way, and the device can be hung on the ground by using a crane.

The invention has the advantages of relatively simple manufacture, smaller area of the platform per se than that of a conventional construction platform, less steel material consumption of the structural frame, capability of saving the use of a wooden gangplank and a supporting scaffold to a greater extent and lower manufacturing cost. The platform moves along with the propulsion of the welding of the cylinder body, has strong operability, safety and reliability, and is very suitable for the installation and welding operation of a multi-section annular cylinder body structure on site.
