As shown in fig. 1 and 2, the spraying device for the special-shaped inner wall of the large-sized cylinder in the embodiment adapts to spraying operation of the inner wall of the cylinder with various complicated and special-shaped internal structures through the adjustable support bracket with adjustable support size and the leg assembly with adjustable length.
Specifically, the spray coating device includes a short nozzle 100 and an adjustment bracket 200 provided on the short nozzle; the nozzle 400 for spraying is provided at one end of the short nozzle 100, the long nozzle 500 is connected to the other end of the short nozzle 100, the long nozzle 500 may be a hose, and the spray gun 600 is connected to the other end of the long nozzle 500. The short spray pipe and the nozzle are stably supported by the adjusting bracket, so that the short spray pipe and the nozzle can stably extend into the barrel.
As shown in fig. 2, the adjusting bracket 200 includes a fixed portion 202 fixedly disposed on the short nozzle 100, a sliding portion 203 slidably engaged with the short nozzle, and two sets of leg assemblies 201 disposed between the fixed portion and the sliding portion, where the number of leg assemblies may be set according to the actual structure inside the cylinder, and three or more sets of leg assemblies are disposed to provide more stable support for the nozzle; or three or more groups of leg assemblies are arranged on the adjusting bracket, and the number of leg assemblies which are actually put into use can be set by adjusting the length of legs in the leg assemblies when the leg assembly is used, so that the number of leg assemblies is not limited here.
In this embodiment, the structure of the spraying device will be described by taking two sets of leg assemblies as an example. The two sets of leg assemblies 201 are symmetrically disposed about the short nozzle. The leg assembly 201 comprises two legs 211, wherein one end of one leg 211 is hinged to the fixing portion 202, one end of the other leg 211 is hinged to the sliding portion 203, and the two legs 211 are hinged to each other in a scissor-fork structure. Through adjusting the position of sliding part on short spray tube, adjustable landing leg subassembly action to the supporting effect scope of adjusting the landing leg subassembly, with the barrel size that adapts to different sizes, bore, make landing leg subassembly's landing leg free end can support on the bearing structure of barrel inside, realize the stable supporting effect to the nozzle.
A positioning member 300 is provided on the short nozzle 100, wherein the positioning member is used to limit the movement of the sliding part on the short nozzle after the sliding part is adjusted to a proper position, thereby limiting the movement of the leg assembly and realizing stable support of the leg assembly. The positioning member 300 in this embodiment is disposed outside the sliding portion 203, and the positioning member 300 is connected to the short nozzle 100 by a screw. The end face of the outer side of the sliding part abuts against the positioning part, the sliding part is driven to move by adjusting the position of the positioning part on the short spray pipe, the position of the sliding part is adjusted, and the adjustment of the adjusting support is realized. Produce the interact power between the free end of landing leg and the inside bearing structure of barrel in the adjustment process, restriction landing leg subassembly's motion has restricted the inboard motion of sliding part, and on the other hand then restricts the motion of sliding part outside through the setting element, realizes spacing to the sliding part, realizes spacing to adjusting the support, makes adjusting the support and can remain stable support all the time. By adopting the limiting adjusting mode, the adjusting is convenient, the structure is simple, and the structure function is stable.
Further, a sliding groove may be provided on the short nozzle 100, and a sliding block engaged with the sliding groove may be provided on the sliding portion 203 to limit the movement of the sliding portion on the short nozzle, so as to guide the sliding portion.
