Lifting appliance for cylinder

Abstract

The invention discloses a lifting appliance for a cylinder. The lifting appliance comprises a lifting ring, a cross rod and a grabbing device. The lifting ring is arranged above the grabbing device through the cross rod, and a lifting point position is provided for lifting of the grabbing device. The lifting appliance is characterized in that the lifting appliance further comprises a clamping device; the grabbing device comprises a left pawl and a right pawl, and the left pawl and the right pawl are symmetrically arranged at the two ends of the clamping device; each pawl comprises a front pawl arm and a rear pawl arm, wherein the front pawl arm and the rear pawl arm are hinged to each other and are in a crossing shape, and the lower end of the front pawl arm and the lower end of the rear pawl arm are bent oppositely to form a clamping part; and the clamping device is used for adjusting the distance between the clamping parts in the front pawl arms and the rear pawl arms. The lifting appliance has the beneficial effects that the lifting appliance is simple, easy to operate and stable in lifting process, the quality problem caused by premature wear of a spindle cover is avoided through lifting under fixing of the pawls, and the lifting appliance can be suitable for multiple machine types.

Description

technical field [0001] The invention relates to the technical field of hangers, in particular to a cylinder hanger. Background technique [0002] Cylinder block sling is an auxiliary tool for hoisting the cylinder block when assembling the engine. For example, the hoisting of the engine body on the line and off the line requires the use of the sling. The traditional cylinder hoist is generally a simple hook, which needs to be manually righted to ensure the stability of the cylinder during hoisting. The hoisting process has the disadvantages of being unstable and easy to fall, which is likely to cause safety accidents, and the joint surface between the hook and the main shaft cover during the hoisting process The contact causes early wear of the lower main shaft cover, which affects the performance of the diesel engine. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a simple and easy-to-operate hoisting device...
