the pull rod 110 forms a lever structure by hooking the pull rod hook 130 to a protruding portion of the bottom wall of the diesel engine body 10 and rotating the shaft 140 as a fulcrum. At the same time, the spring exerts an elastic pre-load force on the drawbar hook 130.
The first abutting part 120 abuts against the pipe wall of the end part of the diesel engine water inlet branch pipe 22 of the gap opening.
The pull rod 110 is rotated in a first direction away from the pull rod hook 130, so that the first abutting portion 120 is displaced in a second direction opposite to the first direction, and the diesel engine water inlet branch pipe 22 is pushed into the second direction until the mounting hole at the end of the diesel engine water inlet branch pipe 22 at the gap is aligned with the flange hole on the water collecting pipe 20.
According to the method, a lever structure is formed by the pull rod hook 130, the rotating shaft 140 and the pull rod 110, in the process of prying the pull rod 110, one end of the diesel engine water inlet branch pipe 22 is jacked into the diesel engine connector through the first supporting part 120 connected to the second end 112 of the pull rod 110, and then the other end of the diesel engine water inlet branch pipe 22 is fixed in the flange plate 21 on the water collecting pipe 20 through a bolt, so that sealing connection is realized.
Referring to fig. 4, one end of the diesel inlet manifold 22 is inserted into the diesel connector in alignment with the other end of the diesel inlet manifold 22 being positioned substantially at the flange 21 of the manifold 20. When the quick assembling and disassembling jig 100 for the water inlet branch pipe of the diesel engine is used for installation, firstly, the elastic member 132 is compressed, the pull rod hook 130 is extended into the protruding part of the bottom wall of the diesel engine body 10, and the pull rod hook 130 is hooked on the protruding part of the bottom wall of the diesel engine body 10. And the first abutting portion 120 is adjusted to make the abutting portion 1212 be clamped on the pipe wall of the diesel engine water inlet branch pipe 22. At this time, the pull rod hook 130 is hooked on the protruding portion of the bottom wall of the diesel engine body 10 above the water collecting pipe 20, the spring generates pressing force to the pull rod hook 130, and the pull rod hook 130 forms a fulcrum. Then, the top leg 152 of the second abutting portion 150 abuts against the diesel engine body 10. Through adjusting handle 160, can be through the fine setting to the position of joint portion 1212, can push into diesel engine water inlet branch pipe 22 through prying handle 160 for diesel engine water inlet branch pipe 22's one end enters into in the diesel engine interface. And the other end of the diesel inlet manifold 22 is aligned with the flange 21 on the manifold 20. The diesel engine water inlet branch pipe 22 is then connected to the flange 21 of the water collecting pipe 20 by bolts. Or the length of the second abutting portion 150 is extended by adjusting the nut 153 and the screw rod 151, so that the first abutting portion 120 pushes one end of the diesel engine water inlet branch pipe 22 into the diesel engine port, and the other end of the diesel engine water inlet branch pipe 22 is aligned with the flange 21 on the water collecting pipe 20. After the installation is accomplished, through reverse adjusting nut 153, not hard up second supports the butt of portion 150 and diesel engine body 10 to can loosen this diesel engine intake branch pipe quick assembly disassembly anchor clamps 100 with diesel engine body 10 and be connected, through pressing down the spring, can take out pull rod hook 130 from diesel engine body 10 below.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
