Description
Technical Field
[0001] This utility model relates to the field of hydropower engineering installation equipment design technology, specifically a telescopic and detachable shed for stator and rotor assembly. Background Technology
[0002] The stators and rotors of hydropower stations are assembled from silicon steel sheets and other auxiliary components in a fixed shed. Once assembled, the entire assembly is hoisted into the turbine pit. During assembly, strict requirements are placed on the temperature, humidity, and cleanliness of the assembly environment. Furthermore, components must be hoisted into the assembly station through the top of the shed, and most power stations have multiple stators and rotors operating simultaneously. Therefore, a well-sealed shed with a frequently openable top, facilitating disassembly during hoisting, is necessary to ensure assembly quality while simultaneously saving resources, reducing procedures, and mitigating risks.
[0003] Currently, assembly sheds in the industry lack reliable sealing measures at the bottom where they contact the ground and between the walls. The roof uses a steel structure with a single, operable hoisting hole in the center. This type of shed has poor sealing performance and typically fails to meet assembly environment requirements. When hoisting components, the hoisting hole must be manually opened. Furthermore, since the roof is a monolithic steel structure, it needs to be dismantled when the stator and rotor are assembled and hoisted as a whole. This dismantling work is extensive, involves significant risks of working at height, and fails to meet current construction requirements for reliable quality, high efficiency, and safe operation. Summary of the Invention
[0004] This utility model discloses a telescopic and detachable shed for stator and rotor assembly. The purpose of this utility model is to provide a stator and rotor assembly shed that is reliable in operation, efficient in construction, and safe in operation.

[0007] The canopy of this utility model includes sliding supports, a driving device, and a canopy, and is a foldable, fully openable structure. Two parallel sliding rails are fixed to the top of the horizontal beams on the left and right facades, respectively, and each rail is an inverted grooved suspension rail. Multiple sets of sliding supports are arranged in parallel, each set including two sets of double-headed rollers and a transverse support rod. The double-headed rollers slide in the grooves of the sliding rails, and the two sets of double-headed rollers are connected to the transverse support rods by a roller axle. The canopy is loaded on the parallel transverse support rods. The driving device includes a drive motor and a drive chain. The drive motor drives the sliding supports to move along the rails in both forward and reverse directions through the drive chain to open and close the canopy.
[0008] Furthermore, sheet metal is used to seal the junctions of each facade, and flexible rubber is used to seal the bottom edge with the ground.
[0009] Furthermore, the main frame of the front facade includes: three main columns and two auxiliary columns arranged in parallel vertically, one horizontal beam, multiple horizontally arranged reinforcing bars, a sandwich structure with an outer panel filled with fireproof and heat-insulating material in the sandwich layer; each main column is provided with a seat plate at its lower end, which is fixed to the ground base plate with screws; two lifting lugs are arranged above the top horizontal beam; the horizontal reinforcing bars are welded to the main columns to form a whole; the lower end of the outer panel is sealed with flexible rubber to the ground, and the flexible rubber is fixed to the outer panel by a pressure plate.

[0011] Furthermore, the main frame of the left facade includes: five parallel vertically arranged main columns, one horizontal beam and several horizontal reinforcing rods, a sandwich structure with an outer panel filled with fireproof and heat-insulating material in the sandwich layer; each main column is provided with a seat plate at its lower end, which is fixed to the ground base plate with screws; two lifting lugs are arranged above the horizontal beam; the horizontal reinforcing rods are welded to the main columns to form a whole; the lower end of the outer panel is sealed with flexible rubber to the ground, and the flexible rubber is fixed to the outer panel by a pressure plate.
[0012] Furthermore, the main frame of the rear facade includes: five parallel vertically arranged main columns, one horizontal beam and several horizontal reinforcing bars, a sandwich structure with an outer panel filled with fireproof and heat-insulating material in the sandwich layer; each main column is provided with a seat plate at its lower end, which is fixed to the ground foundation plate with screws; two lifting lugs are arranged above the horizontal beam; the horizontal reinforcing bars are welded to the main columns to form a whole; the lower end of the outer panel is sealed with flexible rubber to the ground, and the flexible rubber is fixed to the outer panel with a pressure plate.

When the stator and rotor are assembled and need to be hoisted, simply remove the locking screws between the main column base plate and the foundation plate, and then use the lifting lugs above the crossbeams to dismantle the front facade for easy overall hoisting. The roof is an automatic telescopic structure. When hoisting assembly parts, the remote-controlled drive motor rotates forward to open the roof; after hoisting, the remote-controlled drive motor rotates backward to close the roof. When the stator and rotor are assembled and need to be hoisted, the remote-controlled drive motor rotates forward to fully retract the roof, allowing the stator and rotor to be hoisted without removing the roof. The sheet metal edging and flexible rubber sealing provide excellent sealing for the workshop shed.
[0017] This utility model relates to a telescopic, detachable stator and rotor assembly shed. The roof can be remotely controlled, making component hoisting convenient and efficient. The combination of sheet metal edging and flexible rubber sealing enhances the shed's sealing effect, making it easier to control the internal environment and ensure assembly quality. After the stator and rotor are assembled, hoisting can be completed without removing the roof, reducing dismantling procedures, avoiding high-altitude dismantling work, and lowering operational risks.
