Described pull bar via hole is divided into two groups, respectively in the clamping plate inner side being fixed on chuck.
Reversal hanger is two covers, and every cover reversal hanger comprises two attaching partss and three steel ropes.The lower end of described each attaching parts is connected with the upper end of steel cable respectively, and the upper end of described each attaching parts is connected with the two ends with steel cable.The lower end of the steel rope that described and lower end each attaching parts is connected is all connected with transition piece.
Described transition piece is U-shaped part, and at the bottom of this transition piece U-lag, there is the contiguous block of protrusion one end, has the connecting bore of perforation on this contiguous block.The line of centers of described connecting bore is perpendicular to the side surface of contiguous block.
Described attaching parts comprises two connecting cleats and pipe link.The plank of described each connecting cleat is two-layer.All there is screw at two ends at each connecting cleat, at the middle part of each connecting cleat, have pin-and-hole.All there is pin-and-hole at the two ends of described pipe link.The two ends of described pipe link pack in connecting cleat, and by pin, one end of this pipe link and connecting cleat middle part are linked.
When each attaching parts is connected with each steel rope, the two ends of steel cable are tied respectively and encircled and pack between the two-layer plank of described connecting cleat upper end, bolt is packed into the screw of this end connecting cleat and tightens up; The upper end knot ring of two steel ropes is packed between the two-layer plank of connecting cleat lower end, bolt is packed into the screw of this end connecting cleat and tightens up.
Need to be equipped with special tooling and the step that has potential safety hazard, the present invention proposes a kind of for large-scale non-metal combustion chamber lifting upset frock.
In order to solve the problems of the technologies described above, the present embodiment utilizes 2 chucks, scuffing of cylinder bore that non-metal combustion chamber is stuck between two chucks, by the major and minor hook of crane, hung respectively two width suspenders and the suspender other end be connected on the hanger of chuck, the lifting of controlling crane major-minor hook realizes the starting point upset of non-metal combustion chamber.So just do not need the band contacting with housing, the position that chuck inner side contacts with non-metal shell is used Rubber washer to protect, and in lifting process, other frock does not contact with housing, can eliminate the hidden danger of quality that housing rubs wound; Because combustion chamber is installed by chuck, pull bar, in lifting process, two ends are all connected with suspender, can avoid toppling over of in lifting combustion chamber, can eliminate safe hidden trouble.

The specific embodiment
The present embodiment is a kind of for large-scale non-metal combustion chamber lifting upset frock, comprises chuck, chuck hanger 3, pull bar and reversal hanger 5.
Chuck 6 has two, is annular arrangement, for the combustion chamber that is installed.One side circular surfaces of this chuck 6 has the snap ring of protrusion, and the internal diameter of this snap ring is identical with the external diameter of the engine chamber being lifted.At described chuck 6, there is the circular surfaces of snap ring to be pasted with rubber pad, and make described rubber pad in snap ring; Internal circular surfaces at described snap ring is also pasted with rubber pad.
Circumferential surface at chuck is fixed with hanger 3, and hanger is for lifting and upset engine chamber.Described hanger comprises clamping plate and suspension rod.End face center, suspension rod one end have a screw, the suspension rod other end and clamping plate are connected.In the two side wall panels of described U-shaped clamping plate, there is concentric tapped bore.
