Description
Technical Field
The utility model relates to a tool, in particular to a tool for replacing an air safety valve of a hydroelectric generating set.
Background
When the air safety valve of the hydroelectric generating set is replaced, the safety valve needs to be detached from the pressure gas tank, and the safety valve is detached on a herringbone ladder or a platform ladder at present. The method has the following defects in overhauling: 1) The space is limited by the pressure vessel fence and the position is high, so that the personnel work position is inconvenient. 2) When the safety valve is replaced, the gravity center of the personnel is unstable, and the side fall accident is easy to happen.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a tool for replacing an air safety valve of a hydroelectric generating set, which is convenient to disassemble and assemble the safety valve, safe and efficient.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a hydroelectric set air relief valve changes frock, includes the platform, and the platform top sets up the guardrail, and platform one side articulates there is the straight ladder, and in the pressure vessel rail was arranged in to the straight ladder, the platform opposite side articulates there is the inclined ladder, and the inclined ladder is arranged in outside the pressure vessel rail.
The lower end of the platform is reinforced by a reinforcing beam.
The platform outside is fixed with a plurality of mount pads, vertically is equipped with the sleeve on the mount pad, guardrail and sleeve grafting assembly.
And universal wheels are arranged on the inclined ladder or the straight ladder.
The inclined ladder or the straight ladder is formed by splicing multiple sections.
The utility model relates to a tool for replacing an air safety valve of a hydroelectric generating set, which has the following technical effects:
1) The safety valve can be replaced on the platform by installing the foldable ladder below the platform, so that the problems of small space below and difficult construction are overcome, and the overhaul operation efficiency is improved.
2) The straight ladder and the inclined ladder can be formed by splicing multiple sections along the length direction and connecting the straight ladder and the inclined ladder through bolts, so that the heights of the straight ladder and the inclined ladder can be adjusted according to safety valves with different installation heights, and the flexibility is improved.

In the figure: platform 1, guardrail 2, pinhole 3, vertical ladder 4, inclined ladder 5, universal wheel 6, hinge 7, pressure vessel rail 8, pressure vessel 9, relief valve 10, reinforcing beam 11, mount pad 12, sleeve 13.
Detailed Description
As shown in figures 1-5, the tool for replacing the air safety valve of the hydroelectric generating set is made of aluminum alloy, has high strength and rigidity, good rust resistance and light weight. The device includes platform 1, and platform 1 is T type structure, and the front end is wide, and the rear end is narrow, makes things convenient for the manual work to dismantle the relief valve and places spare part. The left side and the right side of the platform 1 are fixedly provided with a plurality of groups of mounting seats 12, each group of mounting seats 12 is vertically welded with a sleeve 13, and two vertical rods of one group of guardrails 2 are inserted into each two groups of sleeves 13, so that the guardrails 2 can be detachably mounted and play a role in left and right protection. The front end of the platform 1 is hinged with the straight ladder 4 through the hinge 7, the straight ladder 4 can rotate 90 degrees, the straight ladder 4 can be supported when vertical, and other structures on the pressure gas tank can be replaced up and down through the straight ladder 4. The inclined ladder 5 is hinged to the rear end of the platform 1 through the hinge 7, the inclined ladder 5 is narrow in upper part and wide in lower part, the whole gravity center of the ladder can not easily fall out of a supporting point of the ladder on the ground, when a person moves on the ladder, the gravity center of the ladder is in the vertical space range of the installation platform, and the side falling accident of the platform is prevented. The inclined ladder 5 is arranged outside the pressure vessel fence 8, and the inclined ladder 5 can support the platform 1 after being unfolded, and is convenient for people to go from the inclined ladder 5 to the platform 1.
The lower end of the platform 1 is reinforced by a reinforcing beam 11. The supporting strength of the platform 1 is improved, and the reliability and stability of the platform structure are ensured.
The inclined ladder 5 or the straight ladder 4 is provided with a universal wheel 6. Thereby facilitating transfer.
As shown in fig. 6-7, the inclined ladder 5 and the straight ladder 4 are all formed by multi-section splicing. Taking a straight ladder 4 as an example for illustration, the straight ladder 4 comprises left and right supporting beams 4.1 and middle steps 4.2, the two supporting beams 4.1 and the steps 4.2 are connected into a whole to form ladder units, two ends of each ladder unit are respectively provided with a socket 4.3 and a plug 4.4, the sockets 4.3 and the plugs 4.4 are transversely provided with perforations 4.5, and adjacent ladder units are spliced through the sockets 4.3 and the plugs 4.4 and can be fixed through bolts. The lengths of the inclined ladder 5 and the straight ladder 4 can be adjusted according to the safety valves with different heights.
Working principle and process: as shown in fig. 1, when in use, the vertical ladder 4 is unfolded and fixed in the pressure container fence 8, then the inclined ladder 5 is unfolded and fixed outside the pressure container fence 8, the safety belt is hung on the guardrail 2, and an operator can stand on the platform 1 to replace the safety valve 10. When the safety valve 10 is installed, the straight ladder 4 and the inclined ladder 5 can be folded and then removed through the universal wheel 6.
