Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

a simple measuring pull rod for the inner diameter of a cylinder of a boiler pressure vessel comprises a handle 1, a connecting rod 2 is sleeved in the handle 1, a baffle 3 is arranged at the upper end of the connecting rod 2, the lower end of the connecting rod 2 is connected with a plurality of Y-shaped supporting rods A4, the upper end of a Y-shaped supporting rod A4 is connected with a supporting rod B5, a sliding groove 6 is formed in the supporting rod B5, a telescopic ruler 7 is arranged in the sliding groove 6, a limiting groove 8 is formed in the left side of the supporting rod B5, a shifting rod 9 is arranged in the limiting groove 8, an adjusting hand wheel 10 is connected to the right side of the supporting rod B5, a scale A11 is arranged at the upper part of the connecting rod 2, and a scale B12 is arranged on the telescopic ruler 7; through setting up two Y shape bracing piece A4 and bracing piece B5 that length equals, make the user pass through pulling baffle 3, make Y shape bracing piece A4 and bracing piece B5 link and barrel inner wall contact, the lower extreme point of Y shape bracing piece A4 of reunion, distance and Y shape bracing piece A4 and bracing piece B5 length between the bracing piece B5 upper end point, can calculate the perpendicular distance of Y shape bracing piece A4 and bracing piece B5 link and connecting rod 2 axis.

Specifically, handle 1 and connecting rod 2 sliding connection, connecting rod 2 is connected fixedly with baffle 3 for this device can carry out the reading outside the barrel.

Further, the connecting rod 2 is rotatably connected with the Y-shaped supporting rod a4, the Y-shaped supporting rod a4 is rotatably connected with the supporting rod B5, and the supporting rod B5 is rotatably connected with the grip 1, so that the connecting rod 2 can push the Y-shaped supporting rod a4 upwards when moving upwards.

Furthermore, the length of the Y-shaped support bar a4 is equal to that of the support bar B5, and the distance from the lower end rotation pivot of the Y-shaped support bar a4 to the central axis of the connecting rod 2 is equal to the distance from the upper end rotation pivot of the support bar B5 to the central axis of the connecting rod 2, so that a user can calculate the distance from the connecting end of the Y-shaped support bar a4 and the support bar B5 to the central axis of the connecting rod 2.
