Description

Clamp connection shell segmentation tool

Technical Field

The utility model relates to a clamp hookup casing segmentation technical field specifically is a clamp hookup casing segmentation frock.

Background

The clamp connection structure is widely applied to the connection of large-scale shells due to the advantages of simple structure, convenient operation and the like. The clamp connection structure generally includes two housings fitted through a spigot, two sealing rings are coaxially disposed on the fitting circular surface, and a clamping groove for accommodating the clamp is disposed on the outer circular surface of each housing, as shown in fig. 3. In each link of shell assembly, performance debugging, delivery, maintenance and the like, the closing and segmenting operations of the two shells are required to be frequently carried out. The operation of closing the sections can be carried out by a vacuumizing method, but in the process of segmenting, the friction resistance of a sealing ring needs to be overcome simultaneously, and due to the influences of factors such as the self weight and the rigidity of the shell and the end socket, the central overlapping degree of each shell in the assembling and disassembling processes and the like, the operation of disassembling the sections is difficult, and even the sealing surface of the shell is extruded and pulled to be scrapped.

What current general segmentation frock adopted is the formula clamp of embracing, encircles through hinge structure and treats tearing open the casing excircle, increases clamp and casing excircle frictional force through fastening bolt, realizes the mutual removal of two shell parts through screw thread or lead screw structure again between two clamps. However, the tool has the following disadvantages: 1) the body is heavy and needs to be matched with lifting equipment; 2) the operation is complicated, the clamp is fastened, the threads or the screw rods need to be rotated for both opening and closing, the matching length of the shell is 60mm, the thread has a long idle running distance from the leading-in to the action of the threads, the time is wasted, and the occupation of personnel and tools is also great; 3) when the shell with higher rigidity is applied, enough holding force is needed to overcome the friction force between the matching surfaces of the O-shaped ring and the shell, so that time and labor are wasted; 4) the cylinder section of this product spherical head is less, and the splitting operation between head and casing can't be carried out to this frock of normal use.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving the technical problem of current clamp connection casing segmentation difficulty.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model discloses a clamp hookup casing segmentation frock, including first ring and the second ring, first ring and second ring all are formed by two semicircle ring concatenations, the connection can be dismantled to the one end hinge of two semicircle rings and the other end, the inner wall of first ring and the second ring's inner wall all are equipped with the bulge loop with casing draw-in groove adaptation, the outer wall of first ring and the second ring's outer wall all have two at least bosss along its circumference equipartition, and the boss of first ring and the second ring's boss correspond and arrange, be equipped with the screw on the boss of first ring, correspond on the second ring's the boss the screw is equipped with the blind hole, and the blind hole diameter is greater than the screw diameter, and threaded connection has the ejector pin in the screw.

Furthermore, the other ends of the two semicircular rings are provided with connecting parts, and the two connecting parts are provided with the same screw rod in a penetrating mode and are provided with butterfly nuts for locking.

Furthermore, the convex ring is in clearance fit with the clamping groove of the shell, and the inner wall of the first ring and the inner wall of the second ring are in clearance fit with the outer wall of the shell.

The utility model has the advantages that:

1) the tool has simple structure, is light and saves labor;

2) the transmission of the sectional axial force is converted into the thrust between the convex ring and the clamping groove from the friction force between the hoop and the shell, the transmission of the force is more stable, and the deformation of the shell caused by extrusion is greatly reduced;

3) the first ring, the second ring and the shell are in clearance fit, and the adjustment operation is quick and convenient when the deflection phenomenon occurs in the shell disassembling process.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1 to 2, the utility model provides a clamp connection shell segmentation tool, which comprises a first ring 1 and a second ring 2, wherein the first ring 1 and the second ring 2 are formed by splicing two semicircular rings, one end of each semicircular ring is hinged and the other end is detachably connected, the detachable connection is a fixed connection and can be realized by adopting common structures such as bolts, buckles or magnets; the inner wall of the first ring 1 and the inner wall of the second ring 2 are provided with a convex ring 3 matched with the clamping groove of the shell, the outer wall of the first ring 1 and the outer wall of the second ring 2 are provided with at least two bosses 4 along the circumferential uniform distribution, the bosses 4 of the first ring 1 and the bosses 4 of the second ring 2 are arranged correspondingly, the bosses 4 of the first ring 1 are provided with screw holes, the bosses 4 of the second ring 2 are correspondingly provided with blind holes, the diameters of the blind holes are larger than the diameters of the screw holes, and the screw holes are internally screwed with ejector rods 6.

When needing the segmentation, will treat the casing of split and place on interfacing apparatus, dismantle the clamp, install first ring 1 and second ring 2 respectively in the draw-in groove of waiting to tear the casing open, link firmly the other end of two semicircle rings. Rotating the ejector rod 6 by a wrench, inserting the ejector rod 6 into the blind hole of the second ring 2 after penetrating through the screw hole, converting the rotary motion of the ejector rod 6 into linear motion, continuously rotating the ejector rod 6, and realizing the separation of the two shells by the matching of the convex ring 3 and the clamping groove.

As an optimal structure that the other end of two semicircle rings links firmly, the other end of two semicircle rings all is equipped with connecting portion 5, and two connecting portion 5 wear to be equipped with same screw rod jointly and dispose butterfly nut locking.
