Embodiment 1

[0032] Such as figure 2 As shown, the embodiment of the present invention provides a welding method of a double rope groove pulley, the method comprising:

[0033] Step 201: Place at least one double-groove pulley to be welded on the roller frame and keep the axis of the double-groove pulley horizontal.

[0034] Specifically, side guide wheels can be arranged on both sides of the tire frame. When the double rope groove pulley is placed on the tire frame, the side guide wheels are close to the end face of the double rope groove pulley, preferably in contact with the double rope groove pulley. But it does not hinder its circular rotation, so as to prevent the double rope groove pulley from toppling over.

[0035] Preferably, before the step 201, the method further includes: axially fixing at least two double rope pulleys together. In this way, several double rope pulleys can be placed at one time, saving working time.

[0036] Specifically, in this embodiment, at least two d...

Embodiment 2

[0045] An embodiment of the present invention provides a welding device for a double rope groove pulley, which is suitable for realizing the welding method described in Embodiment 1. Such as image 3 As shown, the welding equipment includes: a tire frame 8 for placing and rotating double rope groove pulleys to be welded, side guide wheels 9 arranged on both sides of the tire frame 8, and welding equipment 10, the side guide wheels 9 are close to The end faces of the double rope groove pulley 12 are set.

[0046] Preferably, the welding device also comprises locking means 7 for axially securing together at least two double rope pulleys. In this embodiment, 4 double-groove pulleys.

[0047] In this example, if Figure 4 As shown, the locking device 7 includes a cylinder 71, a cover plate 72 and a bolt 73, the outer diameter of the cylinder 71 matches the inner hole of the hub of the double rope pulley 12, and one end of the cylinder 71 is provided with an outer flange 74 , t...

Abstract

The embodiment of the invention discloses a welding method and welding equipment of a double-rope groove pulley, and belongs to the technical field of machine manufacture. The method comprises the following steps of: placing at least one double-rope groove pulley to be welded on a rolling tire frame and keeping an axis of the double-rope groove pulley to be horizontal; preheating a part of the double-rope groove pulley to be welded till reaching 100 DEG C-150 DEG C; and carrying out submerged-arc welding on the part of the double-rope groove pulley after preheating. The equipment comprises the rolling tire frame, a side guide wheel and the welding equipment. According to the embodiment of the invention, the pulley tire frame is adopted for ensuring the double-rope groove pulley to be vertically placed, the pulley tire frame is used for rotating the double-rope groove pulley to be welded, and the welding position can keep immutability; and a submerged-arc welding horizontal welding mode is adopted, the depth of fusion penetration is large, the welding quality is good and stable, primary acceptability is high, the production cycle is greatly shortened, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a welding method and welding equipment for a double rope groove pulley. Background technique [0002] In ship lifts, double rope groove pulleys with large diameters (such as 3.5m-5.5m in diameter) are usually used. Such large diameter double rope pulleys are usually welded from several parts, which usually include large steel rings, small steel rings, webs, hubs, ribs and rims. A rim is welded at both ends of the large steel ring, while the small steel ring is welded between the rim and the hub through the web. Among them, the thickness of the large steel ring is generally 35mm-45mm, and the length of the weld between it and the rim is 10m-20m, requiring 200kg-400kg of deposited metal, and the amount of deposited metal is large. [0003] When adopting existing welding method to weld big steel ring and wheel rim, be to put big steel ring and wheel horizontally u...
