Abstract

The invention relates to a handling truck making the operations of servicing and of setting pneumatic actuators equipping industrial pipe fittings, and particularly those of the nuclear industry, easier. The moving truck (1) is fitted with a support (2) to which the actuator to be inspected is fastened; this support can pivot through 360 DEG and can be locked in any position whatsoever chosen by the operator. Two adjustable and retractable stops (3) allow the actuator to rest in a stable fashion while the handling slings are being removed, and allow it to be fastened to the pivoting support. A rack and pinion system makes it possible to perfect the positioning for installation on the support.

Description

CHARIOT PIVOTANT POUR MAINTENANCE DES ACTIONNEURS PN ERATIZU ES
On sait que la maintenance des actionneurs pneumatiques équipant un grand nombre d'appareils de robinetterie,se déroule en régle générale dans condition de travail lu adaptées, bien souvent a meme le sol, et dans des zones pouvant présenter des risques, tel que la contamination nucléaire, chimique ou autres.
PIVOTING CART FOR MAINTAINING PN ERATIZU ES ACTUATORS
We know that the maintenance of pneumatic actuators equipping a large number of valves, takes place as a rule in working condition read adapted, often even on the ground, and in areas that may present risks, such as contamination nuclear, chemical or other.

Le chariot de manutention objet de l'invention et tout particuliérement destiné à la maintenance des actionneurs de poids variant de 50 à 200 kgs équipant la robinnetterie des centrales nucléaires EDF, il en rend le travail plus aisé-et avec plus de formalisme, car aprés desac; couplement de l'actionneur de partie robinnetterie proprement dite, il permet d'éffectuer,soit. sur place, soit par déplacement dans des zônes a moindre risques, toutes les opérations de maintenance et de réglage des actionneurs, dans toptes les positions de ceux-ci sur 360 , dans des conditions normales de travail.The handling trolley object of the invention and especially intended for the maintenance of actuators of weight varying from 50 to 200 kgs equipping the taps of EDF nuclear power plants, it makes their work easier - and with more formalism, because after of bag; coupling of the valve part actuator proper, it makes it possible to perform, either. on site, either by moving in areas with less risk, all maintenance and adjustment operations of the actuators, in all the positions of these on 360, under normal working conditions.

Le chariot objet de 1' invention voir FI. 1 eut 2 est essentiellement constitue d'un chassis mobile, et d'un support pivotant dans l'axe principal du chassis, et sur lequel est fixé l'actionneur a visiter.The trolley object of the invention see FI. 1 eut 2 is essentially constituted by a mobile chassis, and a support pivoting in the main axis of the chassis, and on which is fixed the actuator to be visited.

Le chassis se compose d'un cadre 1 et d' une traverse centrale 2 en fer U de 80, ce chassis est équipé de quatre roulettes sur bandage caoutchouc de 150mm environ, dont deux sont fixes 3 et deux pivotantes 4 avec dispositif de blocage aux pieds.The chassis consists of a frame 1 and a central crosspiece 2 made of iron U of 80, this chassis is fitted with four castors on rubber tires of approximately 150mm, two of which are fixed 3 and two swivel 4 with blocking device. feet.

Sur 1' un des cotés du cadre 1 et sur la traverse centrale 2,Sont soudés,deux bras verticaux 5 également en fer U de 80mm,a la partie supérieure de chaque bras est soudé un coussinet en acier 6, dont. 1 'intérieur est bague en bronze, servant d'articulation au support pivotant.On one of the sides of the frame 1 and on the central crossmember 2, are welded, two vertical arms 5 also made of iron U of 80mm, at the upper part of each arm is welded a steel pad 6, of which. 1 interior is bronze ring, serving as articulation to the pivoting support.

Le support pivotant sur lequel se positionne,et se fixe l'actionneur a visiter,se compose, de deux bras 7 en tôle d'acier d,'épaisseur 12mm possedant,soude,a 1 une de leur extremite un tourillon 8 qui emmanché dans les coussinets 6 des bras verticaux du chassis servent d'axe de rotation a l'ensemble pivotant. La forme de ces bras est telle ,qu'elle assure le passage du centre de gravité de 1' actionneur G par l'axe des tourillons permettant ainsi l'équilibrage de l'ensemble eh rotation
A l'autre extrémité de chacun des deux bras sont fixes par vis les supports 9 proprement dit,supports qui peuvent êtres differents en forme et en dimensionnement suivant le type de l'actionneur a visiter (dans le cas present sont descripts des supports pour des actionneurs possedant des oreilles de manutention solidaire du flasque superieur) ils sont constitués par un fer U fixe par vis 10 sur l'éxtrémite des bras articulés 7 et porte a l'autre extrémité un axe fileté 11 avec collerette, pour centrage et fixation avec rondelle et écrou, de 1 actionneur, par ses oreilles de manutention. une demicouronne 12 en tol e d'acier d'epaisseur 8mm, soudée sur chaque éxtrémité des supports en U, rendent l'ensemble monobloc,ensemble qui pourra donc etre déposé des deux bras pivotant ee comme mentionne precedemment remplacé dans une certaine mesure, par d'autres supports adaptés aux différents types d'actionneurs.
The pivoting support on which is positioned, and is fixed the actuator to be visited, is made up of two arms 7 made of sheet steel, 12mm thick having, welded, at 1 of their ends a pin 8 which fitted into the bearings 6 of the vertical arms of the chassis serve as an axis of rotation for the pivoting assembly. The shape of these arms is such that it ensures the passage of the center of gravity of the actuator G by the axis of the trunnions thus allowing the balance of the assembly to be rotated
At the other end of each of the two arms are fixed by screws the supports 9 proper, supports which can be different in shape and dimensioning according to the type of actuator to be visited (in the present case are descriptions of the supports for actuators having handling ears integral with the upper flange) they are constituted by an iron U fixed by screws 10 on the end of the articulated arms 7 and carries at the other end a threaded pin 11 with flange, for centering and fixing with washer and nut, of 1 actuator, by its handling ears. a half-crown 12 in steel tol 8mm thick, welded to each end of the U-shaped supports, make the unit monobloc, an assembly which can therefore be removed from the two pivoting arms as mentioned previously replaced to some extent by other supports adapted to different types of actuators.

Afin de controler la rotation de l'ensemble pivotant,les coussinets 6 soudés a l'extrémite des bras verticaux du chassis ; sont fendus longitudinalement, permettant pour 1' un,par un systéme 13 goujon, écrou et contre-ecrou, de régler par pincement la liberté en rotation du support. et pour 1 ' autre, par un goujon et une manette indexable 14 dans assurer le blocage dans la position choisie par 1 'opérateur
Pour faciliter la mise en place et la fixation de l'actionneur sur le support pivotant, deux taquets éscamotables 15 coulissent et se positionnent sur les bras verticaux du chassis,en fonction du dimenssionnement des actionneurs.
In order to control the rotation of the swivel assembly, the bearings 6 welded to the end of the vertical arms of the chassis; are split longitudinally, allowing for one, by a system 13 stud, nut and locknut, to pinch the freedom of rotation of the support. and for the other, by a stud and an indexable lever 14 in blocking in the position chosen by the operator
To facilitate the positioning and fixing of the actuator on the pivoting support, two retractable tabs 15 slide and are positioned on the vertical arms of the chassis, depending on the dimensioning of the actuators.

Ils se composent voir FIG.3.et 4 d'une équerre 16 en tôle soudée, une corniére 17 fixée à l'éxtrémite de son aile horizontale sert de repos a l'actionneur et en assure la stabilité pendant le temps de dépose des élingues de manutention,et de sa fixation sur le support pivotant.Le maintien en position de ces taquets est assure par 1 'arc-boutement de liaxe 18, solidaire de l'équerre par deux circlips 19, et un pignon 20 (15 dents,module 2,5) placé en opposition et se déplacant sur une cremaillére 21 fixée par vis 30 sur le bras vertical, la rotation du pignon 20 étant assurée par
