Description

Technical Field

[0001] The utility model relates to the technical field of mounting bases, in particular to a maintenance platform base. Background Art

[0002] At present, due to the need to inspect the flood discharge channel of a hydropower station, an inspection platform needs to be used to perform construction work in the flood discharge channel. Therefore, it is necessary to develop an inspection platform base for the dam inspection platform of a hydropower station. The common dam inspection platform base is usually made of steel or alloy materials. Although it has strong bearing capacity and stability and can meet the bearing requirements during operation. However, this structure also has disadvantages: since the dam inspection platform is usually large, the volume of its base is also large, which is not convenient for transportation and installation; and the existing base is a flat plate structure as a whole, which has a large wind resistance; in addition, the base has a large deadweight and does not meet the lightweight requirements. Utility Model Content

[0003] The utility model provides a maintenance platform base, the purpose of which is to reduce the transportation volume and facilitate hoisting operations.

[0004] The utility model is achieved through the following technical scheme: a maintenance platform base, including a base body, the base body including a bottom plate and a frame, the bottom plate is connected to the top surface of the frame, the bottom plate includes a main bottom plate and a secondary bottom plate, the frame includes a main frame and a secondary frame, the main bottom plate and the secondary bottom plate are respectively connected to the top surfaces of the main frame and the secondary frame, and the main frame and the secondary frame are detachably connected.

[0008] Beneficial effect: The guide wheel mechanism in this scheme can make the base of the maintenance platform move along a predetermined route and guide the movement of the maintenance platform. It is used to move along the direction of the flow channel when walking, so that the guide wheel can act on the side wall of the flow channel, so that the maintenance platform will not deviate during movement.

[0012] Beneficial effect: In this solution, the locking mechanism is used to fix the base. When the base of the maintenance platform is in place, the telescopic drive unit drives the locking block to move away from the frame and firmly attach to the wall, so that the base of the maintenance platform will not move or slip, ensuring the overall stability of the maintenance platform and the safety of operation.

[0013] Furthermore, the telescopic driving unit is a hydraulic cylinder, a cylinder body of the hydraulic cylinder is connected to the frame, and a telescopic rod of the hydraulic cylinder is connected to the locking block.

[0014] Beneficial effects: In this solution, the telescopic drive unit adopts a hydraulic cylinder, and the locking block can be driven away from or close to the frame through the telescopic movement of the telescopic rod of the hydraulic cylinder, thereby achieving the function of locking the base or unlocking the base, which is flexible and convenient to use.

[0015] Furthermore, guide rods are provided on both sides of the hydraulic cylinder, one end of the guide rod is connected to the locking block, and the other end of the guide rod passes through the frame and vertically slides with the side wall of the frame.

[0021] Furthermore, the main bottom plate and the auxiliary bottom plate are both connected with lifting rings.

[0022] Beneficial effect: The setting of the lifting ring facilitates the lifting operation during assembly, and facilitates the lifting operation of the whole in the flow channel after the base is connected and fixed with the rest of the maintenance platform.

[0023] Furthermore, there are four lifting rings on each of the main bottom plate and the auxiliary bottom plate, and the four lifting rings are distributed in the shape of a rectangular array.

[0024] Beneficial effect: With this arrangement, the lifting points are more evenly distributed, and the lifting of the main base plate and the auxiliary base plate is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
