Embodiment 1

[0022] like figure 1 As shown, an imported full pavement car hanging oil cylinder cylinder set crack oil leakage oil repair method, including the following steps: 1), telescopic cylinder cylinder set cracking treatment; 2), preheating before retractable cylinder tank welding; 3), Argon arc welding; 4), telescopic cylinder cylinder sleeve after heat treatment; 5), telescopic cylinder cylinder set inside and outside the outer side grinding; 6), telescopic cylinder cylinder block mounting card.

[0023] The crack excavation treatment refers to the removal of the telescopic cylinder from the imported full pavement car hanging main arm, and the portion of the cylinder cylinder sleeve is grinded with a grinding machine until the root of the crack is removed.

[0024] Preheating preheating is preheated with a tank-type ceramic electric heating plate, and a thermocouple detection temperature is used, and the preheating temperature is 200 ° C.

[0025] Arc welding welding is referred to th...

Embodiment 2

[0033]Based on the first embodiment, step 7) also includes a rail, sensor, and tubing on the card 8. After three days of operation, the strength of the wear-resistant repair replenishment reaches the design value, the guide rail, sensor bracket is welded on the hold card, and finally mount the rail, sensor, tubing, and finally return the assembled telescopic cylinder to the telescopic arm.

[0034] Wear-resistant corrosion-resistant replenishment adhesive resistant tonic is used in JL2205 titanium alloy. Performance: Titanium silicon metal synthesis, high hardness, resistance to wear resistance, corrosion resistance, can be used to friction, wear conditions, precision mechanical equipment and components. When coating, the mixed repair will be mixed, and the average amount is applied to the surface, compacted, so that the work layer is sufficient, and the remaining amount is left for processing, and the binder can be used with acetone, alcohol cleaning. Curing in a temperature of 2...

Abstract

The invention relates to a method for repairing cracked oil leakage of a telescopic oil cylinder liner of an imported all-terrain truck crane, which belongs to the field of lifting equipment. Compared with the overall replacement of telescopic cylinders in foreign countries, the comprehensive repair process of crack digging, argon arc welding, post-weld heat treatment, and production of clamps solves the problem of oil leakage from cracks in telescopic cylinders, prolongs the service life of telescopic cylinders, and ensures that all roads The truck crane is safe, high-quality and efficient to use, and at the same time, the cost is relatively low and the construction period is short. In terms of economic benefits, compared with the maintenance method of replacing the telescopic hydraulic cylinder as a whole, the repair cycle is shorter, the labor cost is low, and the material cost is low, which has a high industry promotion value.

Description

Technical field [0001] The present invention relates to an imported full pavement of automotive spray oil cylinder cylinder crack oil leakage oil retaining method, belonging to the field of lifting equipment. Background technique [0002] In recent years, it has penetrated hydraulic technology in various industries and production sectors, which gives a huge role in improving product quality, expanding production capacity and improving production efficiency. However, the cylinder is used as a common power transfer assembly in the hydraulic system, and its operational reliability is stable and whether the stability and safety of the entire hydraulic system are directly affected by the stability and security of the hydraulic system. This is in some special equipment layout, shape size, installation. Method, the vibration caused by external factors is more prominent. [0003] The large arm expansion cylinder on the imported full pavement car is equipped with the above specialty. The ...
