Description

Main control room coil platform mosaic takes out instrument

Technical Field

The utility model belongs to the technical field of the nuclear power overhauls, concretely relates to master control room coil platform mosaic instrument of taking out.

Background

The master control room of the nuclear power plant generally adopts a mosaic plate platform, the plate platform is designed to resist shock, the bottom of the plate platform is a grid type frame, and mosaics are compactly arranged on the frame. Taking a certain third-generation nuclear power generating unit as an example, more than 90 about 12000 mosaics of different types are arranged on a main control room panel platform, and the mosaic comprises an alarm indicator lamp, a recorder, a measuring instrument, a manual-automatic change-over switch, a start-stop button and the like. The mosaic is mostly made of plastic materials, mainly has two specifications of 24mm × 48mm and 48mm × 48mm, and the mass is generally not more than 50 g. According to the design, the mosaics need to be arranged closely, the distance between different mosaics is generally 0.5-1.0 mm under the influence of installation and manufacturing precision, and because the distance between adjacent mosaics is very small, the mosaics are difficult to take out by a common tool and are easily damaged.

Before the taking-out tool is used, no good taking-out tool exists in China, tweezers are generally adopted to clamp out or a screwdriver is used to pry out, the working efficiency is low, and mosaics are easy to damage and deform. Because of the existence of electronic components on the mosaic plate table, pure metal components such as tweezers are easy to get an electric shock, and the risk of short circuit of the electric components exists.

the lower part processing of body has the barb, when stretching into the body between the adjacent mosaic, can locate the mosaic outer edge on by the card, and then takes out the instrument through the vertical upwards promotion, takes out the mosaic.

The left side edge of the body is provided with a ruler A, and 0 scale is arranged on the lower edge of the body and used for reading the depth of the inserted mosaic, so that the situation that the mosaic stretches into an element part which is too deep and contacts the lower part to cause short circuit is avoided.

And a ruler B is arranged on the right edge of the body, and 0 scale is arranged on the lower edge of the barb and used for reading the distance of the barb extending into the mosaic to judge whether the mosaic reaches a clamping position.

N barbs are provided, wherein N is more than or equal to 1; when the clamping device is used for taking out a large mosaic, more barbs can be arranged side by side so as to enable the clamping device to be more stable.

Processing a screw hole in the center of the upper part of the body, and fixing the bodies with different thicknesses together through a connecting bolt and a nut to form a set; when the mosaic is taken out, the body with proper thickness is selected and connected with the heat-shrinkable sleeve to start operation.

The upper part of the body is processed into a semicircular edge or a chamfer, so that the insertion and the taking are convenient and the damage to the heat-shrinkable sleeve is avoided; two feet of the body are processed into 1/4 circular arcs.

The beneficial effects of the utility model reside in that:

(1) the utility model discloses can convenient and fast ground take out the mosaic, both save follow-up maintenance time, can improve equipment reliability again, can also guarantee user's safety.

(2) The utility model discloses the device adopts one-way barb, and the barb is closed when inserting, can pass through the mosaic clearance smoothly, treats to insert enough degree of depth after, the barb because metal stress expandes automatically, takes out the mosaic smoothly.

(3) The utility model discloses the device is applicable to the narrow and small operational environment in space clearance, portable, operation.

(4) The utility model discloses the device is complete sets, can select different instruments according to different clearances.

(5) The utility model discloses device heat shrinkage bush is for dismantling, is applicable to the complete set equipment.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A master control room coil platform mosaic taking tool shown in figure 1 is used for taking out a mosaic 5 on a nuclear power plant master control room mosaic coil platform shown in figure 4, and comprises a heat-shrinkable sleeve 1, a body 2 and barbs 3.

The body 2 is of a rectangular sheet structure, and the heat-shrinkable sleeve 1 is sleeved on the upper portion of the body 2 and used as a hand-held portion to be convenient to grab and insulate. The upper portion processing of body 2 is semicircle limit or chamfer, conveniently inserts and gets and avoid scratching bad heat-shrinkable sleeve 1, and two footing processing of body 2 are 1/4 circular-arcly.

The lower part of the body 2 is provided with a barb 3 which can be clamped on the outer edge 6 of the mosaic when the body 2 is inserted between adjacent mosaics 5. The number of the barbs 3 is N, wherein N is larger than or equal to 1, and when the large mosaic 5 is taken out, more barbs 3 can be arranged side by side so that the clamping is more stable, as shown in fig. 2.

A ruler A is arranged on the left edge of the body 2, and 0 scale is arranged on the lower edge of the body 2 and used for reading the depth of the mosaic 5 to avoid the situation that the mosaic 5 extends too deep to contact with a component below to cause short circuit; and a ruler B is arranged on the right edge of the body 2, and 0 scale is arranged on the lower edge of the barb 3 and used for reading the distance of the barb 3 extending into the mosaic 5 so as to judge whether the mosaic reaches a clamping position.

As shown in fig. 3, a screw hole is formed in the center of the upper portion of the main body 2, and the main bodies 2 having different thicknesses are fixed together by a connecting bolt 4 and a nut to form a set.

When the mosaics are taken out, the distance between the outer edges 6 of the adjacent mosaics is measured by a vernier caliper, then the connecting bolt 4 and the nut on the taking-out tool sleeve are unscrewed, and the body 2 with proper thickness is selected to be connected with the heat-shrinkable sleeve 1; the side, provided with the barb 3, of the body 2 is opposite to the mosaic 5 to be taken out, the body 2 extends into the gap of the mosaic 5 to exceed a certain depth, and the barb 3 is clamped on the outer edge 6 of the mosaic; and finally, vertically lifting the taking-out tool upwards to take out the mosaic 5.
