Abstract

PURPOSE:To aim at speeding up the operation of tube bundle insertion, by inserting a bundle tip into a body and, after a support base plate of a truck at the body side is made to go down, lifting up the truck with a rocking arm via an auxiliary wheel orthogonal with a guide rail, then pulling it out to the sideward. CONSTITUTION:A tip end of a tube bundle is pulled in a body by a crane and simultaneously supported inside the body, then a support base plate 21 of a truck nearest to the body is made to go down by a jack 22, while a supporting device at the side opposite to a drawing direction of the truck is removed. Next, with a hydraulic cylindsr 26, two rocking arms 25 are rocked downward, while auxiliary wheels at both sides are made to go down on a guide base plate set up in a direction orthogonal with a guide rail 33, then the turck as a whole is lifted up, and the truck 12 is drawn out of the guide rail 33 via the auxiliary wheels 24 to the outside. Next, the tube bundle 11 is further pulled in the body 32 again by the crane, and with the same process, the second truck 12 is drawn outward. Thus, the insertion operation of the tube bundle is easily and speedily performable.

る。Structure of the conventional example and its problems During the manufacturing of the heat exchanger, there is a step of inserting the tube bundle into the body. Conventionally, when inserting a tube bundle into a fuselage, as shown in FIG. 1, the tube bundle (1) is suspended by a crane (not shown) via a wire (2), and the tube bundle (1) is
After placing the cart (3) at the rear end, pull the cart (3) forward with the wire (4) to release the tube bundle (
1) was inserted into the fuselage (5). However, according to the above method, the heavy tube bundle (1) is connected to the wire (
When hoisting in step 2), a protector (6) is interposed in the lift, but there is a risk that the protector (6) will be squeezed and deformed. As a method to overcome this drawback, a method has already been used in which the tube bundle is placed on multiple trolleys and inserted into the fuselage, but in this case, the trolleys must be removed one by one from the rail, and the Removal work was extremely difficult and time consuming. Further, as a method of solving this drawback, it is possible to install a rotary switch at the location where the truck is removed, but this is uneconomical because the cost required for installation of the switch is high.

バンドルを胴体内に挿入する方法である。Structure of the Invention In order to achieve the above object, the method for inserting a tube bundle into a heat exchanger according to the present invention provides a method for inserting a tube bundle into a heat exchanger body by inserting a dolly body having guide wheels on a guide rail disposed corresponding to the body opening of the heat exchanger. A dolly comprising: a support base plate supported on the dolly body so as to be movable up and down; and auxiliary wheels provided at the tips of swinging arms attached to both sides of the dolly body so as to be swingable in a vertical plane. At the same time, a plurality of tube bundles are placed on each support base plate of these carts, and then the tube bundle is moved to the fuselage side via the cable, and the tip of the tube bundle is inserted and supported into the fuselage. Then, after lowering the support base plate of the bogie near the body, the swinging arm is swung downward so that it is arranged in a direction perpendicular to the guide rail and its upper surface is in contact with the upper surface of the guide rail and the road surface. In this method, the entire truck is lifted up on the auxiliary wheels on the guide base plate, and then the truck is pulled out laterally from the guide rails using the auxiliary axle, and the tube bundles are sequentially inserted into the body.
