Description

A spray hanger

technical field

The utility model relates to the technical field of spraying production equipment, in particular to a spraying hanger.

Background technique

With the rapid development of my country's wind power industry, especially large-capacity megawatt-level large-scale wind turbines, the use of high-strength fasteners and wind power bolts for wind power equipment is also increasing. Due to long-term field service, harsh environment, and poor maintenance conditions, wind power bolts usually need to guarantee a service life of more than 10 years. Wind turbine bolts often require a coating on their outer surface to protect them. When spraying, usually the wind power bolts to be sprayed are clamped on the fixture, and then put into the spray booth for spraying. The current fixture usually adopts the method of screw fixing and clamping. Firstly, the wind power bolt workpiece is placed on the fixture, and then the screw is tightened to tighten the workpiece. Due to the stress interaction relationship when the workpiece is clamped, all parts cannot be hung on the same straight line to form a row, and only two rows of parallel suspension can be adopted. Therefore, the hanging quantity of the parts on the same hanger is limited, and the utilization efficiency of the coating is low during spraying, generally below 30%, which causes a great waste of coating and low production efficiency.

detailed description

Referring to FIG. 1 , the spraying hanger includes two parallel vertical rods 1 arranged left and right, and the vertical rods 1 are arranged in the vertical direction and are in the shape of elongated rods. The vertical bar 1 is provided with a horizontally arranged high cross bar 2 and a low cross bar 3 , and the high cross bar 2 is above the low cross bar 3 . A row of push rods 21 arranged in a straight line are fixedly arranged on the high cross bar 2 , and the push rods 21 are evenly arranged on the high cross bar 2 , and the distance between two adjacent push rods 21 is equal.

The low horizontal bar 3 is fixedly installed on the vertical bar 1, and the low horizontal bar 3 is provided with a row of spring locking mechanisms arranged in a straight line, and each spring locking mechanism is directly below a push rod 21. Referring to Fig. 2, the spring locking mechanism includes a spring 5 and a movable rod pressed on the spring 5, and the movable rod is mounted on the low cross bar 3 so as to move up and down. The movable rod includes a bolt 41 and a nut 42 matched with the bolt 41 . The spring locking mechanism also includes a large through hole 31 and a small through hole 32 arranged on the low cross bar 3 in the vertical direction, the large through hole 31 and the small through hole 32 are coaxial, and the axis of the two is a vertical direction, and the large through hole 31 is in the vertical direction. Above the small through hole 32 , the diameter of the large through hole 31 is larger than that of the small through hole 32 . The spring 5 is helical, and its outer diameter is larger than the aperture of the small through hole 32 and smaller than the aperture of the large through hole 31. The spring 5 is placed in the large through hole 31 and will not fall out of the small through hole 32. The diameter of the bolt 41 is smaller than the inner diameter of the spring 5 and can pass through the spring 5 . The bolt 41 passes through the small through hole 32 and the large through hole 31 sequentially from bottom to top, and passes through the spring 5 . The nut 42 is screwed on the bolt 41 and pressed on the spring 5 . The outer diameter of the nut 42 is smaller than the diameter of the large through hole 31 and can enter the large through hole 31 . When the workpiece is placed on the spraying rack, it is only necessary to clamp the two ends of the workpiece 10 between the push rod 21 and the bolt 41 in the same vertical direction, and the spring 5 can adjust the position of the bolt 41 according to the length of the workpiece. Workpieces of different lengths can be clamped. Adjusting the position of the nut 42 on the bolt 41 can adjust the distance between the push rod 21 and the bolt 41 on the one hand to adapt to the needs of workpieces of different lengths, and also can adjust the pressing force of the spring 5 on the other hand. If select the spring that length is longer than big through hole 31 when being selected for use, the diameter of nut 42 also can be greater than the aperture of big through hole 31. The spring locking mechanism adopted in this embodiment has the advantages of strong adaptability to workpieces of different lengths, strong pressing force, simple structure, easy assembly and convenient use.

Referring to FIG. 1 , a plurality of adjustment locking holes 11 are arranged on the vertical bar 1 , the plurality of adjustment locking holes 11 are arranged in a row along the vertical direction, and the adjustment locking holes 11 extend in the horizontal direction.
