Description

Technical Field

[0001] The utility model relates to the technical field of vertical shaft repair, in particular to a construction platform erecting structure during vertical shaft repair. Background Art

[0002] With the increase of usage time and the implementation of new process equipment, various problems inevitably arise in the original shaft wall, such as frequent water gushing from the shaft wall of the vertical shaft. Once water comes out of the shaft, many safety hazards will arise, and even some safety accidents will occur. Therefore, the shaft wall needs to be repaired to ensure the safe use of the shaft. When repairing the shaft wall of a vertical shaft, there are often multiple water gushing points with different elevations, so it is necessary to set up and dismantle construction platforms at multiple places with different elevations. The labor intensity of the operators is high, and the construction cost and efficiency are low. Summary of the invention

[0003] In order to solve the problem that construction platforms need to be respectively erected and dismantled at multiple water gushing points when repairing the wall of a vertical shaft, thereby resulting in high labor intensity for operators, low construction costs and efficiency, the utility model provides a new construction platform erecting structure for repairing the shaft.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A construction platform erection structure for repairing a vertical shaft, comprising a cage, two construction platforms, and two hydraulic cylinders, one side end portions of the two construction platforms being respectively hinged to the left and right side portions of the top of the cage (it is well known to those skilled in the art that the cross-section of the cage is rectangular, and the front and rear sides of the cage are very close to the wall of the shaft, so the water gushing points on the front and rear sides of the shaft can be repaired at the top of the cage without setting up a construction platform, while the left and right sides of the cage are far from the wall of the shaft to facilitate construction personnel to get on and off the cage, so a construction platform is required), and the axial directions of the hinged shafts are arranged along the front-to-back direction, the fixed ends of the two hydraulic cylinders are fixed to the top of the cage, and the telescopic ends thereof are respectively abutted against the bottoms of the two construction platforms, and when the telescopic ends of the two hydraulic cylinders are contracted to the limit, the two construction platforms are in a horizontal arrangement, and the other side ends of the two construction platforms are supported on the original steel beams of the shaft wall.

[0006] During repair, the cage stops at the water gushing point on the wall of the vertical shaft. The operator starts the hydraulic cylinder, retracts the telescopic end of the hydraulic cylinder corresponding to the side where the water gushing point needs to be repaired to the limit, so that the corresponding construction platform is horizontally arranged and the other end of the construction platform supports on the original corresponding steel beam on the wall of the vertical shaft. The operator repairs the wall of the vertical shaft through the constructed construction platform. After the repair is completed, the hydraulic cylinder is operated again, the telescopic end of the hydraulic cylinder extends, the construction platform is lifted, and the construction platform smoothly rises or falls with the cage to another water gushing point, repeating the above steps.

[0007] Furthermore, both construction platforms are fixedly erected and crossed in a warp and weft pattern by a plurality of longitudinal steel pipes with their axial directions arranged in the front-back direction and a plurality of transverse steel pipes with their axial directions arranged in the left-right direction. The structure is specific and standardized, and the construction platforms have high strength and good stability.

[0008] Furthermore, one end of each of the two construction platforms is hinged to the top of the cage through a plurality of fixing bases evenly distributed in the front-back direction. Each fixing base is U-shaped, and the two ends of the pin shaft are respectively rotatably connected to the front and rear vertical arms of the fixing base. The transverse steel pipe of each construction platform is fixed to the middle of the pin shaft. The structure is specific and standardized.

[0009] The beneficial effects produced by the present utility model are as follows: The present utility model utilizes the cage and the original steel beam to erect the construction platform, controls the rise and fall of the construction platform by using the hinge structure and the hydraulic cylinder, and can be reused, avoiding the frequent demolition and erection of the construction platform, reducing the labor intensity of the operators, lowering the construction cost, and effectively improving the construction efficiency.

One end portions of the two construction platforms are respectively hinged to the left and right side portions at the top of the cage 2 (it is well known to those skilled in the art that the cross section of the cage 2 is rectangular, and the front and rear sides of the cage 2 are very close to the wall of the vertical shaft 1, so the water inrush points on the front and rear sides of the vertical shaft 1 can be repaired at the top of the cage 2 without erecting a construction platform, while the left and right sides of the cage 2 are far from the wall of the vertical shaft 1 because it is convenient for construction workers to get on and off the cage 2, so a construction platform needs to be erected), and the axial directions of the hinge shafts are all arranged along the front and rear directions. The fixed ends of the two hydraulic cylinders 6 are both fixed to the top of the cage 2, and their telescopic ends respectively abut against the bottoms of the two construction platforms. When the telescopic ends of the two hydraulic cylinders 6 contract to the limit, the two construction platforms are both horizontally arranged, and the other end portions of the two construction platforms are both supported on the original steel beam 3 on the wall of the vertical shaft 1.

The operator repairs the wall of the vertical shaft 1 through the erected construction platform. After the repair is completed, the hydraulic cylinder 6 is operated again, and the telescopic end of the hydraulic cylinder 6 extends, and the construction platform is lifted. The construction platform smoothly rises or falls with the cage 2 to another repair point, and the above steps are repeated.

[0021] During specific implementation, both construction platforms are fixedly erected in a crisscross manner by a plurality of longitudinal steel pipes 5 whose axial directions are all arranged in the front-back direction and a plurality of transverse steel pipes 4 whose axial directions are all arranged in the left-right direction, with the structure being specific and standardized, and the construction platforms having high strength and good stability.

[0022] During specific implementation, one end of each of the two construction platforms is hinged to the top of the cage 2 through a plurality of fixing bases 7 evenly distributed in the front-back direction. Each fixing base 7 is U-shaped. The two end portions of the pin shaft 8 are respectively rotatably connected to the front and rear vertical arms of the fixing base 7, and the transverse steel pipe 4 of each construction platform is fixed to the middle of the pin shaft 8, with the structure being specific and standardized.
