Technical Field
[0001] This application relates to the technical field of chimney construction, and particularly to an aerial work and transportation device for chimneys. Background Art
[0002] With the rapid development of the national power industry, the construction safety and efficiency of tall structures such as chimneys have become important considerations. In traditional construction methods for internal steel structures of chimneys, such as using aerial gondolas, the gondolas shake significantly during lifting and lowering, presenting problems such as high safety risks, high resource consumption, and high operation difficulty. Such methods not only affect the construction progress and quality but also increase construction costs and labor consumption. Therefore, it is necessary to develop a new type of aerial work and transportation device for chimneys to solve the problems existing in the prior art. Content of the Utility Model
[0003] In view of the above problems, this application provides an aerial work and transportation device for chimneys.
[0004] The technical solution adopted by the aerial work and transportation device for chimneys provided by this application is as follows:
[0005] An aerial work and transportation device for chimneys includes a chimney outer cylinder, a hoisting assembly, a hoisting platform, and a limiting assembly. A bearing beam is provided at the top of the chimney outer cylinder. The hoisting assembly is fixedly arranged on the bearing beam. The hoisting platform is arranged on the inner wall of the chimney outer cylinder. Two main hoisting seats are arranged on the hoisting platform, and the two main hoisting seats are symmetrically arranged with respect to the top wall of the hoisting platform. The main hoisting seats are fixedly connected to the hoisting assembly. The limiting assembly is used to limit the hoisting platform.
[0006] By adopting the above technical solution, for the provided aerial work and transportation device for chimneys, when constructing the internal steel structure of the chimney, building materials are placed on the hoisting platform. The bearing beam supports the hoisting assembly. The hoisting assembly hoists the main hoisting seats, and the main hoisting seats drive the entire hoisting platform to lift and lower. When the hoisting platform is lifted and lowered, the limiting assembly limits the hoisting platform, preventing the hoisting platform from shifting and shaking and causing damage to the chimney outer cylinder, reducing construction risks. At the same time, construction workers can also perform aerial work on the inner wall of the chimney outer cylinder through the hoisting platform, eliminating the need to erect scaffolding and improving the construction efficiency of the chimney.
[0007] In a specific feasible implementation, the hoisting platform includes a top plate, cross beams, reinforcing beams, load-bearing columns, and a plurality of reinforcing ribs; the cross beams are horizontally arranged between the two load-bearing columns, one end of the reinforcing beam is fixedly connected to the load-bearing column, and the other end extends in the radial direction of the load-bearing column, and a plurality of the reinforcing beams are distributed around the circumferential side wall of the load-bearing column; a plurality of the reinforcing ribs are arranged between two adjacent reinforcing beams; the top plate is fixedly connected to the top wall of the reinforcing beam, the load-bearing column passes through the top plate, and the two load-bearing columns are symmetrically arranged with respect to the upper wall surface of the top plate; two main hoisting seats are respectively fixedly arranged at the ends of the two load-bearing columns passing through the top plate.
[0008] By adopting the above technical solution, for the provided hoisting platform, the cross beams fixedly connect the two load-bearing columns, the reinforcing beams arranged on the circumferential side walls of the two load-bearing columns support the top plate, and the reinforcing ribs between adjacent reinforcing beams improve the overall stability of the reinforcing beams. When lifting the hoisting platform, building materials are placed on the top plate, the hoisting assembly drives the hoisting seats to move, the hoisting seats drive the load-bearing columns to move, and then the reinforcing beams move together with the load-bearing columns. The reinforcing beams support the top plate and the building materials for lifting, which is convenient for transporting the building materials.
[0009] In a specific feasible implementation, the reinforcing beams arranged on the side walls of the two load-bearing columns are symmetric with respect to the cross beam.
[0010] By adopting the above technical solution, the arranged reinforcing beams are symmetric with respect to the cross beam, which is convenient for ensuring that the center of gravity of the hoisting platform is located between the two load-bearing columns. When lifting the hoisting platform, it can avoid the hoisting platform from shifting by itself, thus ensuring the hoisting quality.
[0011] In a specific feasible implementation, the hoisting platform further includes two auxiliary hoisting seats, the auxiliary hoisting seats are symmetrically arranged on the upper wall surface of the top plate, and the line connecting the two auxiliary hoisting seats is perpendicular to the line connecting the two main hoisting seats; the auxiliary hoisting seats are fixedly connected to the hoisting assembly.
[0012] By adopting the above technical solution, for the provided auxiliary hoisting seats, while hoisting the main hoisting seats, the auxiliary hoisting seats are simultaneously stressed, which is convenient for reducing the load on the main hoisting seats and the load-bearing columns; at the same time, the line connecting the main hoisting seats is perpendicular to the line connecting the auxiliary hoisting seats, which is convenient for ensuring that the hoisting platform is symmetrically stressed at multiple points, thereby improving the stability of hoisting.
[0013] In a specific feasible implementation, the hoisting assembly includes two main hoisting pulleys and two auxiliary hoisting pulleys. The main hoisting pulleys and the auxiliary hoisting pulleys are both fixedly arranged on the load-bearing beam, and the two main hoisting pulleys are respectively located above the two main hoisting seats, and the two auxiliary hoisting pulleys are respectively located above the two auxiliary hoisting seats. Steel cables are wound around both the main hoisting pulleys and the auxiliary hoisting pulleys. A hook is fixedly arranged at one end of the steel cable away from the main hoisting pulley and the auxiliary hoisting pulley, and the hooks are respectively hooked on the main hoisting seat and the auxiliary hoisting seat.
[0014] By adopting the above technical solution, the provided hoisting assembly adjusts the main hoisting pulley and the auxiliary hoisting pulley simultaneously. The steel cables on the main hoisting pulley and the auxiliary hoisting pulley move accordingly. The steel cables drive the hooks to hang the main hoisting seat and the auxiliary hoisting seat, and the main hoisting seat and the auxiliary hoisting seat drive the entire hoisting platform to lift and lower, facilitating the transportation of materials on the hoisting platform.
[0015] In a specific feasible implementation, two groups of the limiting assemblies are symmetrically arranged on opposite sides of the hoisting platform. The limiting assembly includes a limiting steel wire rope, a limiting fixing seat, and a limiting sleeve. The limiting fixing seat is anchored to the ground below the hoisting platform. One end of the limiting steel wire rope is fixedly connected to the limiting fixing seat, and the other end is fixedly connected to the load-bearing beam. The limiting sleeve is fixedly connected to the end of the strengthening beam away from the load-bearing column. The limiting sleeve is vertically arranged, and the limiting steel wire rope passes through the limiting sleeve.
[0016] By adopting the above technical solution, the provided limiting assembly, during the lifting and lowering process of the hoisting platform, the limiting sleeve slides on the limiting steel wire rope, and the limiting steel wire rope limits the movement direction of the limiting sleeve, avoiding the hoisting platform from shaking and tilting, thus facilitating the improvement of the hoisting stability.
[0017] In a specific feasible implementation, the hoisting platform further includes a guardrail. The guardrail is fixedly arranged on the top plate, and the guardrail is arranged circumferentially along the upper wall surface of the top plate.
[0018] By adopting the above technical solution, the provided guardrail, during the lifting and lowering process of the hoisting platform, the guardrail protects the building materials or construction personnel on the top plate, preventing the building materials or construction personnel from falling off the hoisting platform, thus facilitating the improvement of the safety of the hoisting platform.
[0019] In summary, the present application includes at least one of the following beneficial technical effects:
